A NOTE ON THE CHANGELOG:
Starting in early 2011, Tcl source code has been under the management of
fossil, hosted at http://core.tcl.tk/tcl/ .  Fossil presents a "Timeline"
fossil, hosted at https://core.tcl-lang.org/tcl/ .  Fossil presents a "Timeline"
view of changes made that is superior in every way to a hand edited log file.
Because of this, many Tcl developers are now out of the habit of maintaining
this log file.  You may still find useful things in it, but the Timeline is
a better first place to look now.

1. Introduction
## <a id="intro">1.</a> Introduction
---------------
Tcl provides a powerful platform for creating integration applications that
tie together diverse applications, protocols, devices, and frameworks.
When paired with the Tk toolkit, Tcl provides the fastest and most powerful
way to create GUI applications that run on PCs, Unix, and Mac OS X.
Tcl can also be used for a variety of web-related tasks and for creating
powerful command languages for applications.

Tcl is maintained, enhanced, and distributed freely by the Tcl community.
Source code development and tracking of bug reports and feature requests
takes place at:

entered into [our issue tracker](https://core.tcl-lang.org/tcl/reportlist).
	http://core.tcl.tk/tcl/reportlist

We will log and follow-up on each bug, although we cannot promise a
specific turn-around time.  Enhancements may take longer and may not happen
at all unless there is widespread support for them (we're trying to
slow the rate at which Tcl/Tk turns into a kitchen sink).  It's very
difficult to make incompatible changes to Tcl/Tk at this point, due to
the size of the installed base.

The Tcl community is too large for us to provide much individual support
for users.  If you need help we suggest that you post questions to
comp.lang.tcl.  We read the newsgroup and will attempt to answer esoteric
questions for which no one else is likely to know the answer.  In addition,

\fBTcl_AttemptAlloc\fR and \fBTcl_AttemptRealloc\fR will not cause the Tcl
interpreter to \fBpanic\fR if the memory allocation fails.  If the
allocation fails, these functions will return NULL.  Note that on some
platforms, but not all, attempting to allocate a zero-sized block of
memory will also cause these functions to return NULL.

The procedures \fBckalloc\fR, \fBckfree\fR, \fBckrealloc\fR,
\fBattemptckalloc\fR, and \fBattemptckrealloc\fR are implemented
as macros.  Normally, they are synonyms for the corresponding
procedures documented on this page.  When Tcl and all modules
calling Tcl are compiled with \fBTCL_MEM_DEBUG\fR defined, however,
these macros are redefined to be special debugging versions
When a module or Tcl itself is compiled with \fBTCL_MEM_DEBUG\fR defined,
the procedures \fBTcl_Alloc\fR, \fBTcl_Free\fR, \fBTcl_Realloc\fR,
\fBTcl_AttemptAlloc\fR, and \fBTcl_AttempRealloc\fR are implemented
as macros, redefined to be special debugging versions of these procedures.
of these procedures.  To support Tcl's memory debugging within a
module, use the macros rather than direct calls to \fBTcl_Alloc\fR, etc.

\fBTcl_RegisterCommandTypeName\fR is used to associate a name (the
\fItypeName\fR argument) with a particular implementation function so that it
can then be looked up with \fBTcl_GetCommandTypeName\fR, which in turn is
called with a command token that information is wanted for and which returns
the name of the type that was registered for the implementation function used
for that command. (The lookup functionality is surfaced virtually directly in Tcl via
\fBinfo cmdtype\fR.) If there is no function registered for a particular
function, the result will be the string literal
.QW \fBnative\fR .
The registration of a name can be undone by registering a mapping to NULL
instead. The result from \fBTcl_GetCommandTypeName\fR will be exactly that
string which was registered, and not a copy; use of a compile-time constant
string is \fIstrongly recommended\fR.

Note that if other code invokes \fBexit\fR system procedure directly, or
otherwise causes the application to terminate without calling
\fBTcl_Exit\fR, the exit handlers will not be run.
\fBTcl_Exit\fR internally invokes the \fBexit\fR system call, thus it never
returns control to its caller.
If an application exit handler has been installed (see
\fBTcl_SetExitProc\fR), that handler is invoked with an argument
consisting of the exit status (cast to ClientData); the application
consisting of the exit status (cast to void *); the application
exit handler should not return control to Tcl.
.PP
\fBTcl_Finalize\fR is similar to \fBTcl_Exit\fR except that it does not
exit from the current process.
It is useful for cleaning up when a process is finished using \fBTcl\fR but
wishes to continue executing, and when \fBTcl\fR is used in a dynamically
loaded extension that is about to be unloaded.

\fBTcl_FindHashEntry\fR is similar to \fBTcl_CreateHashEntry\fR
except that it does not create a new entry if the key doesn't exist;
instead, it returns NULL as result.

\fBTcl_GetHashValue\fR and \fBTcl_SetHashValue\fR are used to
read and write an entry's value, respectively.
Values are stored and retrieved as type
.QW ClientData ,
which is
large enough to hold a pointer value.  On almost all machines this is
large enough to hold an integer value too.

\fBTcl_GetHashKey\fR returns the key for a given hash table entry,
either as a pointer to a string, a one-word
.PQ "char *"
key, or
as a pointer to the first word of an array of integers, depending

\fBTcl_HashStats\fR returns a dynamically-allocated string with
overall information about a hash table, such as the number of

The header file \fBtcl.h\fR defines the actual data structures
used to implement hash tables.
This is necessary so that clients can allocate Tcl_HashTable
structures and so that macros can be used to read and write
the values of entries.
However, users of the hashing routines should never refer directly

To add a handler callback to be invoked when a limit is exceeded, call
\fBTcl_LimitAddHandler\fR.  The \fIhandlerProc\fR argument describes
the function that will actually be called; it should have the
following prototype:
.PP
.CS
typedef void \fBTcl_LimitHandlerProc\fR(
        ClientData \fIclientData\fR,
        void *\fIclientData\fR,
        Tcl_Interp *\fIinterp\fR);
.CE
.PP
The \fIclientData\fR argument to the handler will be whatever is
passed to the \fIclientData\fR argument to \fBTcl_LimitAddHandler\fR,
and the \fIinterp\fR is the interpreter that had its limit exceeded.
.PP
The \fIdeleteProc\fR argument to \fBTcl_LimitAddHandler\fR is a
function to call to delete the \fIclientData\fR value.  It may be
\fBTCL_STATIC\fR or NULL if no deletion action is necessary, or
\fBTCL_DYNAMIC\fR if all that is necessary is to free the structure with
\fBTcl_Free\fR.  Otherwise, it should refer to a function with the
following prototype:
.PP
.CS
typedef void \fBTcl_LimitHandlerDeleteProc\fR(
        ClientData \fIclientData\fR);
        void *\fIclientData\fR);
.CE
.PP
A limit handler may be deleted using \fBTcl_LimitRemoveHandler\fR; the
handler removed will be the first one found (out of the handlers added
with \fBTcl_LimitAddHandler\fR) with exactly matching \fItype\fR,
\fIhandlerProc\fR and \fIclientData\fR arguments.  This function
always invokes the \fIdeleteProc\fR on the \fIclientData\fR (unless
the \fIdeleteProc\fR was NULL or \fBTCL_STATIC\fR).

.SH DESCRIPTION
.PP
\fBTcl_LinkVar\fR uses variable traces to keep the Tcl variable
named by \fIvarName\fR in sync with the C variable at the address
given by \fIaddr\fR.
Whenever the Tcl variable is read the value of the C variable will
be returned, and whenever the Tcl variable is written the C
variable will be updated to have the same value.
\fBTcl_LinkVar\fR normally returns \fBTCL_OK\fR;  if an error occurs
while setting up the link (e.g. because \fIvarName\fR is the
name of array) then \fBTCL_ERROR\fR is returned and the interpreter's result
contains an error message.
.PP
.VS "TIP 312"
\fBTcl_LinkArray\fR is similar, but for arrays of fixed size (given by
the \fIsize\fR argument). When asked to allocate the backing C array
storage (via the \fIaddr\fR argument being NULL), it writes the
address that it allocated to the Tcl interpreter result.
.VE "TIP 312"
.PP
The \fItype\fR argument specifies the type of the C variable,
or the type of the elements of the C array,
and must have one of the following values, optionally OR'ed with
\fBTCL_LINK_READ_ONLY\fR:
.TP
\fBTCL_LINK_INT\fR
.
The C variable is of type \fBint\fR.
The C variable, or each element of the C array, is of type \fBint\fR.
Any value written into the Tcl variable must have a proper integer
form acceptable to \fBTcl_GetIntFromObj\fR;  attempts to write
non-integer values into \fIvarName\fR will be rejected with
Tcl errors. Incomplete integer representations (like the empty
string, '+', '-' or the hex/octal/binary prefix) are accepted
as if they are valid too.
.TP
\fBTCL_LINK_UINT\fR
.
The C variable is of type \fBunsigned int\fR.
The C variable, or each element of the C array, is of type \fBunsigned int\fR.
Any value written into the Tcl variable must have a proper unsigned
integer form acceptable to \fBTcl_GetWideIntFromObj\fR and in the
platform's defined range for the \fBunsigned int\fR type; attempts to
write non-integer values (or values outside the range) into
\fIvarName\fR will be rejected with Tcl errors. Incomplete integer
representations (like the empty string, '+', '-' or the hex/octal/binary
prefix) are accepted as if they are valid too.
.TP

.
The C variable is of type \fBchar\fR.
The C variable, or each element of the C array, is of type \fBchar\fR.
Any value written into the Tcl variable must have a proper integer
form acceptable to \fBTcl_GetIntFromObj\fR and be in the range of the
\fBchar\fR datatype; attempts to write non-integer or out-of-range
values into \fIvarName\fR will be rejected with Tcl errors. Incomplete
integer representations (like the empty string, '+', '-' or the
hex/octal/binary prefix) are accepted as if they are valid too.

new value.
If the C variable contains a NULL pointer then the Tcl variable
will read as
.QW NULL .
This is only supported by \fBTcl_LinkVar\fR.
.PP
If the \fBTCL_LINK_READ_ONLY\fR flag is present in \fItype\fR then the
variable will be read-only from Tcl, so that its value can only be

that class.
.PP
Given a method, the entity that declared it can be found using
\fBTcl_MethodDeclarerClass\fR which returns the class that the method is
attached to (or NULL if the method is not attached to any class) and
\fBTcl_MethodDeclarerObject\fR which returns the object that the method is
attached to (or NULL if the method is not attached to an object). The name of
the method can be retrieved with \fBTcl_MethodName\fR and whether the method
is exported is retrieved with \fBTcl_MethodIsPublic\fR. The type of the method
the method can be retrieved with \fBTcl_MethodName\fR, whether the method
is exported is retrieved with \fBTcl_MethodIsPublic\fR,
.VS TIP500
and whether the method is private is retrieved with \fBTcl_MethodIsPrivate\fR.
.VE TIP500
The type of the method
can also be introspected upon to a limited degree; the function
\fBTcl_MethodIsType\fR returns whether a method is of a particular type,
assigning the per-method \fIclientData\fR to the variable pointed to by
\fIclientDataPtr\fR if (that is non-NULL) if the type is matched.
.SS "METHOD CREATION"
.PP
Methods are created by \fBTcl_NewMethod\fR and \fBTcl_NewInstanceMethod\fR,
which
create a method attached to a class or an object respectively. In both cases,
the \fInameObj\fR argument gives the name of the method to create, the
\fIisPublic\fR argument states whether the method should be exported
initially, the \fImethodTypePtr\fR argument describes the implementation of
\fIflags\fR argument states whether the method should be exported
initially
.VS TIP500
or be marked as a private method,
.VE TIP500
the \fImethodTypePtr\fR argument describes the implementation of
the method (see the \fBMETHOD TYPES\fR section below) and the \fIclientData\fR
argument gives some implementation-specific data that is passed on to the
implementation of the method when it is called.
.PP
When the \fInameObj\fR argument to \fBTcl_NewMethod\fR is NULL, an
unnamed method is created, which is used for constructors and destructors.
Constructors should be installed into their class using the

.PP
The \fIclientData\fR argument to a Tcl_MethodCallProc is the value that was
given when the method was created, the \fIinterp\fR is a place in which to
execute scripts and access variables as well as being where to put the result
of the method, and the \fIobjc\fR and \fIobjv\fR fields give the parameter
objects to the method. The calling context of the method can be discovered
through the \fIobjectContext\fR argument, and the return value from a
Tcl_MethodCallProc is any Tcl return code (e.g. TCL_OK, TCL_ERROR).
.SS "TCL_METHODDELETEPROC FUNCTION SIGNATURE"
.PP
Functions matching this signature are used when a method is deleted, whether
through a new method being created or because the object or class is deleted.

The \fIclientData\fR argument to a Tcl_MethodDeleteProc will be the same as
the value passed to the \fIclientData\fR argument to \fBTcl_NewMethod\fR or
\fBTcl_NewInstanceMethod\fR when the method was created.
.SS "TCL_CLONEPROC FUNCTION SIGNATURE"
.PP
Functions matching this signature are used to copy a method when the object or

The \fIinterp\fR argument gives a place to write an error message when the
attempt to clone the object is to fail, in which case the clone procedure must
also return TCL_ERROR; it should return TCL_OK otherwise.

The procedure \fBTcl_CreateEventSource\fR creates a new event source.
Its arguments specify the setup procedure and check procedure for
the event source.
\fISetupProc\fR should match the following prototype:
.PP
.CS
typedef void \fBTcl_EventSetupProc\fR(
        ClientData \fIclientData\fR,
        void *\fIclientData\fR,
        int \fIflags\fR);
.CE
.PP
The \fIclientData\fR argument will be the same as the \fIclientData\fR
argument to \fBTcl_CreateEventSource\fR;  it is typically used to
point to private information managed by the event source.
The \fIflags\fR argument will be the same as the \fIflags\fR

The second procedure provided by each event source is its check
procedure, indicated by the \fIcheckProc\fR argument to
\fBTcl_CreateEventSource\fR.  \fICheckProc\fR must match the
following prototype:
.PP

typedef void \fBTcl_EventCheckProc\fR(
        ClientData \fIclientData\fR,
        void *\fIclientData\fR,
        int \fIflags\fR);
.CE
.PP
The arguments to this procedure are the same as those for \fIsetupProc\fR.
\fBCheckProc\fR is invoked by \fBTcl_DoOneEvent\fR after it has waited
for events.  Presumably at least one event source is now prepared to
queue an event.  \fBTcl_DoOneEvent\fR calls each of the event sources

Another example of deferring events happens in Tk if
\fBTk_RestrictEvents\fR has been invoked to defer certain kinds
of window events.
.PP
When \fIproc\fR returns 1, \fBTcl_ServiceEvent\fR will remove the
event from the event queue and free its storage.
Note that the storage for an event must be allocated by
the event source (using \fBTcl_Alloc\fR or the Tcl macro \fBckalloc\fR)
the event source (using \fBTcl_Alloc\fR)
before calling \fBTcl_QueueEvent\fR, but it
will be freed by \fBTcl_ServiceEvent\fR, not by the event source.
.PP
Threaded applications work in a
similar manner, except that there is a separate event queue for
each thread containing a Tcl interpreter.

        Tcl_Event *\fIevPtr\fR,
        ClientData \fIclientData\fR);

point to the next event in the queue.

We require the string representation's byte array
to have a null after the last byte, at offset \fIlength\fR,
and to have no null bytes before that; this allows string representations
to be treated as conventional null character-terminated C strings.
These restrictions are easily met by using Tcl's internal UTF encoding
for the string representation, same as one would do for other
Tcl routines accepting string values as arguments.
Storage for the byte array must be allocated in the heap by \fBTcl_Alloc\fR
or \fBckalloc\fR.  Note that \fIupdateStringProc\fRs must allocate
Storage for the byte array must be allocated in the heap by \fBTcl_Alloc\fR.
Note that \fIupdateStringProc\fRs must allocate
enough storage for the string's bytes and the terminating null byte.
.PP
The \fIupdateStringProc\fR for Tcl's built-in double type, for example,
calls Tcl_PrintDouble to write to a buffer of size TCL_DOUBLE_SPACE,
then allocates and copies the string representation to just enough
space to hold it.  A pointer to the allocated space is stored in
the \fIbytes\fR member.

In a freshly loaded Tcl library, \fBTcl_Panic\fR prints the formatted
error message to the standard error file of the process, and then
calls \fBabort\fR to terminate the process.  \fBTcl_Panic\fR does not
return. On Windows, when a debugger is running, the formatted error
message is sent to the debugger in stead. If the windows executable
does not have a stderr channel (e.g. \fBwish.exe\fR), then a
system dialog box is used to display the panic message.
.PP
If your application doesn't use \fBTcl_Main\fR or \fBTk_Main\fR
and you want to implicitly use the stderr channel of your
application's C runtime (in stead of the stderr channel of the
C runtime used by Tcl), you can call \fBTcl_SetPanicProc\fR
with \fBTcl_ConsolePanic\fR as its argument. On platforms which
only have one C runtime (almost all platforms except Windows)
\fBTcl_ConsolePanic\fR is equivalent to NULL.
.PP
\fBTcl_SetPanicProc\fR may be used to modify the behavior of
\fBTcl_Panic\fR.  The \fIpanicProc\fR argument should match the

The type of \fIblockPtr\fR (\fBchar *\fR) is different than the type of the
\fIclientData\fR argument to \fBTcl_EventuallyFree\fR for historical
reasons, but the value is the same.
.PP
When the \fIclientData\fR argument to \fBTcl_EventuallyFree\fR
refers to storage allocated and returned by a prior call to
\fBTcl_Alloc\fR, \fBckalloc\fR, or another function of the Tcl library,
\fBTcl_Alloc\fR or another function of the Tcl library,
then the \fIfreeProc\fR argument should be given the special value of
\fBTCL_DYNAMIC\fR.
.PP
This mechanism can be used to solve the problem described above
by placing \fBTcl_Preserve\fR and \fBTcl_Release\fR calls around
actions that may cause undesired storage re-allocation.  The
mechanism is intended only for short-term use (i.e. while procedures

\fBTcl_RegExpGetInfo\fR retrieves information about the last match
performed with a given regular expression \fIregexp\fR.  The
\fIinfoPtr\fR argument contains a pointer to a structure that is
defined as follows:
.PP
.CS
typedef struct Tcl_RegExpInfo {
    int \fInsubs\fR;
    size_t \fInsubs\fR;
    Tcl_RegExpIndices *\fImatches\fR;
    long \fIextendStart\fR;
    size_t \fIextendStart\fR;
} \fBTcl_RegExpInfo\fR;
.CE
.PP
The \fInsubs\fR field contains a count of the number of parenthesized
subexpressions within the regular expression.  If the \fBTCL_REG_NOSUB\fR
was used, then this value will be zero.  The \fImatches\fR field
points to an array of \fInsubs\fR+1 values that indicate the bounds of each
subexpression matched.  The first element in the array refers to the
range matched by the entire regular expression, and subsequent elements
refer to the parenthesized subexpressions in the order that they
appear in the pattern.  Each element is a structure that is defined as
follows:
.PP
.CS
typedef struct Tcl_RegExpIndices {
    long \fIstart\fR;
    long \fIend\fR;
    size_t \fIstart\fR;
    size_t \fIend\fR;
} \fBTcl_RegExpIndices\fR;
.CE
.PP
The \fIstart\fR and \fIend\fR values are Unicode character indices
relative to the offset location within \fIobjPtr\fR where matching began.
The \fIstart\fR index identifies the first character of the matched
subexpression.  The \fIend\fR index identifies the first character

These routines save the state of an interpreter before a call to a routine such

The first triplet stores the snapshot of interpreter state in
an opaque token returned by \fBTcl_SaveInterpState\fR.  That token

or \fBTcl_DiscardInterpState\fR, depending on whether the interp

It returns a token for the saved state.  The interpreter result is not reset
and no interpreter state is changed.

.PP
The second triplet stores the snapshot of only the interpreter

These routines are passed a pointer to \fBTcl_SavedResult\fR

information in the interpreter (e.g. the \fB\-errorcode\fR or
\fB\-errorinfo\fR return options, when an error is in progress).

Because the routines \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
If a saved state is not restored, \fBTcl_DiscardInterpState\fR must be called

.PP
\fBTcl_SaveInterpState\fR takes a snapshot of those portions of
\fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR, and \fBTcl_DiscardResult\fR are
interpreter state that make up the full result of script evaluation.
This include the interpreter result, the return code (passed in

\fB\-errorinfo\fR and \fB\-errorcode\fR when an error is in progress.
This snapshot is returned as an opaque token of type \fBTcl_InterpState\fR.
The call to \fBTcl_SaveInterpState\fR does not itself change the
state of the interpreter.  Unlike \fBTcl_SaveResult\fR, it does

.PP
\fBTcl_RestoreInterpState\fR accepts a \fBTcl_InterpState\fR token
previously returned by \fBTcl_SaveInterpState\fR and restores the
state of the interp to the state held in that snapshot.  The return
value of \fBTcl_RestoreInterpState\fR is the status value originally
passed to \fBTcl_SaveInterpState\fR when the snapshot token was
created.
.PP
\fBTcl_DiscardInterpState\fR is called to release a \fBTcl_InterpState\fR
token previously returned by \fBTcl_SaveInterpState\fR when that
snapshot is not to be restored to an interp.
.PP
The \fBTcl_InterpState\fR token returned by \fBTcl_SaveInterpState\fR
must eventually be passed to either \fBTcl_RestoreInterpState\fR
or \fBTcl_DiscardInterpState\fR to avoid a memory leak.  Once
the \fBTcl_InterpState\fR token is passed to one of them, the
token is no longer valid and should not be used anymore.

.PP
Once memory debugging support has been compiled into Tcl, the C
functions \fBTcl_ValidateAllMemory\fR, and \fBTcl_DumpActiveMemory\fR,
and the Tcl \fBmemory\fR command can be used to validate and examine
memory usage.
.SH "GUARD ZONES"
.PP
When memory debugging is enabled, whenever a call to \fBckalloc\fR is
When memory debugging is enabled, whenever a call to \fBTcl_Alloc\fR is
made, slightly more memory than requested is allocated so the memory
debugging code can keep track of the allocated memory, and eight-byte
.QW "guard zones"
are placed in front of and behind the space that will be
returned to the caller.  (The sizes of the guard zones are defined by the
C #define \fBLOW_GUARD_SIZE\fR and #define \fBHIGH_GUARD_SIZE\fR
in the file \fIgeneric/tclCkalloc.c\fR \(em it can
be extended if you suspect large overwrite problems, at some cost in
performance.)  A known pattern is written into the guard zones and, on
a call to \fBckfree\fR, the guard zones of the space being freed are
a call to \fBTcl_Free\fR, the guard zones of the space being freed are
checked to see if either zone has been modified in any way.  If one
has been, the guard bytes and their new contents are identified, and a
.QW "low guard failed"

.QW "high guard failed"
message is issued.  The
.QW "guard failed"
message includes the address of the memory packet and
the file name and line number of the code that called \fBckfree\fR.
the file name and line number of the code that called \fBTcl_Free\fR.
This allows you to detect the common sorts of one-off problems, where
not enough space was allocated to contain the data written, for
example.
.SH "DEBUGGING DIFFICULT MEMORY CORRUPTION PROBLEMS"
.PP
Normally, Tcl compiled with memory debugging enabled will make it easy
to isolate a corruption problem.  Turning on memory validation with
the memory command can help isolate difficult problems.  If you
suspect (or know) that corruption is occurring before the Tcl
interpreter comes up far enough for you to issue commands, you can set
\fBMEM_VALIDATE\fR define, recompile tclCkalloc.c and rebuild Tcl.
This will enable memory validation from the first call to
\fBckalloc\fR, again, at a large performance impact.
\fBTcl_Alloc\fR, again, at a large performance impact.
.PP
If you are desperate and validating memory on every call to
\fBckalloc\fR and \fBckfree\fR is not enough, you can explicitly call
\fBTcl_Alloc\fR and \fBTcl_Free\fR is not enough, you can explicitly call
\fBTcl_ValidateAllMemory\fR directly at any point.  It takes a \fIchar
*\fR and an \fIint\fR which are normally the filename and line number
of the caller, but they can actually be anything you want.  Remember
to remove the calls after you find the problem.

.IP "[2] \fBEvaluation.\fR"
A command is evaluated in two steps.
First, the Tcl interpreter breaks the command into \fIwords\fR
and performs substitutions as described below.
These substitutions are performed in the same way for all
commands.
Secondly, the first word is used to locate a command procedure to
carry out the command, then all of the words of the command are
passed to the command procedure.
The command procedure is free to interpret each of its words
Secondly, the first word is used to locate a routine to
carry out the command, and the remaining words of the command are
passed to that routine.
The routine is free to interpret each of its words
in any way it likes, such as an integer, variable name, list,
or Tcl script.
Different commands interpret their words differently.
.IP "[3] \fBWords.\fR"
Words of a command are separated by white space (except for
newlines, which are command separators).

.AP "unsigned int" initValue in
The initial value for the checksum algorithm.
.AP "unsigned char" *bytes in
An array of bytes to run the checksum algorithm over, or NULL to get the
recommended initial value for the checksum algorithm.
.AP int length in
.AP size_t length in
The number of bytes in the array.
.AP int mode in
What mode to operate the stream in. Should be either
\fBTCL_ZLIB_STREAM_DEFLATE\fR for a compressing stream or
\fBTCL_ZLIB_STREAM_INFLATE\fR for a decompressing stream.
.AP Tcl_ZlibStream *zshandlePtr out
A pointer to a variable in which to write the abstract token for the stream
upon successful creation.
.AP Tcl_ZlibStream zshandle in
The abstract token for the stream to operate on.
.AP int flush in
Whether and how to flush the stream after writing the data to it. Must be one
of: \fBTCL_ZLIB_NO_FLUSH\fR if no flushing is to be done, \fBTCL_ZLIB_FLUSH\fR
if the currently compressed data must be made available for access using
\fBTcl_ZlibStreamGet\fR, \fBTCL_ZLIB_FULLFLUSH\fR if the stream must be put
into a state where the decompressor can recover from on corruption, or
\fBTCL_ZLIB_FINALIZE\fR to ensure that the stream is finished and that any
trailer demanded by the format is written.
.AP int count in
The maximum number of bytes to get from the stream, or -1 to get all remaining
bytes from the stream's buffers.
.AP size_t count in
The maximum number of bytes to get from the stream, or TCL_AUTO_LENGTH to get
all remaining bytes from the stream's buffers.
.AP Tcl_Obj *compDict in
A byte array value that is the compression dictionary to use with the stream.
Note that this is \fInot a Tcl dictionary\fR, and it is recommended that this
only ever be used with streams that were created with their \fIformat\fR set
to \fBTCL_ZLIB_FORMAT_ZLIB\fR because the other formats have no mechanism to
indicate whether a compression dictionary was present other than to fail on
decompression.

A mutex is a lock that is used to serialize all threads through a piece
of code by calling \fBTcl_MutexLock\fR and \fBTcl_MutexUnlock\fR.
If one thread holds a mutex, any other thread calling \fBTcl_MutexLock\fR will
block until \fBTcl_MutexUnlock\fR is called.
A mutex can be destroyed after its use by calling \fBTcl_MutexFinalize\fR.
.VS TIP509
The result of locking a mutex twice from the same thread is undefined.
Mutexes are reentrant: they can be locked several times from the same
On some platforms it will result in a deadlock.
thread. However there must be exactly one call to
\fBTcl_MutexUnlock\fR for each call to \fBTcl_MutexLock\fR in order
for a thread to release a mutex completely.
.VE TIP509
The \fBTcl_MutexLock\fR, \fBTcl_MutexUnlock\fR and \fBTcl_MutexFinalize\fR
procedures are defined as empty macros if not compiling with threads enabled.
For declaration of mutexes the \fBTCL_DECLARE_MUTEX\fR macro should be used.
This macro assures correct mutex handling even when the core is compiled
without threads enabled.

successful completion.
If \fIproc\fR returns a non-NULL value it signifies that an
error occurred.
The return value must be a pointer to a static character string
containing an error message,
unless (\fIexactly\fR one of) the \fBTCL_TRACE_RESULT_DYNAMIC\fR and
\fBTCL_TRACE_RESULT_OBJECT\fR flags is set, which specify that the result is
either a dynamic string (to be released with \fBckfree\fR) or a
either a dynamic string (to be released with \fBTcl_Free\fR) or a
Tcl_Obj* (cast to char* and to be released with
\fBTcl_DecrRefCount\fR) containing the error message.
If a trace procedure returns an error, no further traces are
invoked for the access and the traced access aborts with the
given message.
Trace procedures can use this facility to make variables
read-only, for example (but note that the value of the variable
will already have been modified before the trace procedure is
called, so the trace procedure will have to restore the correct
value).
.PP
The return value from \fIproc\fR is only used during read and
write tracing.
During unset traces, the return value is ignored and all relevant
trace procedures will always be invoked.
.SH "RESTRICTIONS"
.PP
A trace procedure can be called at any time, even when there
is a partially formed result in the interpreter's result area.  If
are partially formed results stored in the interpreter.  If
the trace procedure does anything that could damage this result (such
as calling \fBTcl_Eval\fR) then it must save the original values of
the interpreter's \fBresult\fR and \fBfreeProc\fR fields and restore
them before it returns.
as calling \fBTcl_Eval\fR) then it must use the \fBTcl_SaveInterpState\fR
and related routines to save and restore the original state of
the interpreter before it returns.
.SH "UNDEFINED VARIABLES"
.PP
It is legal to set a trace on an undefined variable.
The variable will still appear to be undefined until the
first time its value is set.
If an undefined variable is traced and then unset, the unset will fail
with an error

.SH DESCRIPTION
.PP
These routines convert between UTF-8 strings and Tcl_UniChars.  A
Tcl_UniChar is a Unicode character represented as an unsigned, fixed-size
These routines convert between UTF-8 strings and Unicode characters.  An
Unicode character represented as an unsigned, fixed-size
quantity.  A UTF-8 character is a Unicode character represented as
a varying-length sequence of up to \fBTCL_UTF_MAX\fR bytes.  A multibyte UTF-8
sequence consists of a lead byte followed by some number of trail bytes.
.PP
\fBTCL_UTF_MAX\fR is the maximum number of bytes that it takes to
represent one Unicode character in the UTF-8 representation.
.PP
\fBTcl_UniCharToUtf\fR stores the Tcl_UniChar \fIch\fR as a UTF-8 string
\fBTcl_UniCharToUtf\fR stores the character \fIch\fR as a UTF-8 string
in starting at \fIbuf\fR.  The return value is the number of bytes stored
in \fIbuf\fR.
in \fIbuf\fR. If ch is a high surrogate (range U+D800 - U+DBFF), then
the return value will be 1 and a single byte in the range 0xF0 - 0xF4
will be stored. If you still want to produce UTF-8 output for it (even
though knowing it's an illegal code-point on its own), just call
\fBTcl_UniCharToUtf\fR again specifying ch = -1.
.PP
\fBTcl_UtfToUniChar\fR reads one UTF-8 character starting at \fIsrc\fR
and stores it as a Tcl_UniChar in \fI*chPtr\fR.  The return value is the
number of bytes read from \fIsrc\fR.  The caller must ensure that the
source buffer is long enough such that this routine does not run off the
end and dereference non-existent or random memory; if the source buffer
is known to be null-terminated, this will not happen.  If the input is
a byte in the range 0x80 - 0x9F, \fBTcl_UtfToUniChar\fR assumes the
cp1252 encoding, stores the corresponding Tcl_UniChar in \fI*chPtr\fR
and returns 1. If the input is otherwise
not in proper UTF-8 format, \fBTcl_UtfToUniChar\fR will store the first
byte of \fIsrc\fR in \fI*chPtr\fR as a Tcl_UniChar between 0x0000 and
0x00ff and return 1.
.PP
\fBTcl_UniCharToUtfDString\fR converts the given Unicode string
to UTF-8, storing the result in a previously initialized \fBTcl_DString\fR.
You must specify \fIuniLength\fR, the length of the given Unicode string.

\fBTcl_UniCharLen\fR corresponds to \fBstrlen\fR for Unicode
characters.  It accepts a null-terminated Unicode string and returns
the number of Unicode characters (not bytes) in that string.
.PP
\fBTcl_UniCharNcmp\fR and \fBTcl_UniCharNcasecmp\fR correspond to
\fBstrncmp\fR and \fBstrncasecmp\fR, respectively, for Unicode characters.
They accept two null-terminated Unicode strings and the number of characters
to compare.  Both strings are assumed to be at least \fInumChars\fR characters
to compare.  Both strings are assumed to be at least \fIuniLength\fR characters
long. \fBTcl_UniCharNcmp\fR  compares the two strings character-by-character
according to the Unicode character ordering.  It returns an integer greater
than, equal to, or less than 0 if the first string is greater than, equal
to, or less than the second string respectively.  \fBTcl_UniCharNcasecmp\fR
is the Unicode case insensitive version.
.PP
\fBTcl_UniCharCaseMatch\fR is the Unicode equivalent to
\fBTcl_StringCaseMatch\fR.  It accepts a null-terminated Unicode string,
a Unicode pattern, and a boolean value specifying whether the match should
be case sensitive and returns whether the string matches the pattern.
.PP
\fBTcl_UtfNcmp\fR corresponds to \fBstrncmp\fR for UTF-8 strings. It
accepts two null-terminated UTF-8 strings and the number of characters
to compare.  (Both strings are assumed to be at least \fInumChars\fR
to compare.  (Both strings are assumed to be at least \fIlength\fR
characters long.)  \fBTcl_UtfNcmp\fR compares the two strings
character-by-character according to the Unicode character ordering.
It returns an integer greater than, equal to, or less than 0 if the
first string is greater than, equal to, or less than the second string
respectively.
.PP
\fBTcl_UtfNcasecmp\fR corresponds to \fBstrncasecmp\fR for UTF-8
strings.  It is similar to \fBTcl_UtfNcmp\fR except comparisons ignore
differences in case when comparing upper, lower or title case
characters.
.PP
\fBTcl_UtfCharComplete\fR returns 1 if the source UTF-8 string \fIsrc\fR
of \fIlength\fR bytes is long enough to be decoded by
\fBTcl_UtfToUniChar\fR, or 0 otherwise.  This function does not guarantee
that the UTF-8 string is properly formed.  This routine is used by
procedures that are operating on a byte at a time and need to know if a
full Tcl_UniChar has been seen.
full Unicode character has been seen.
.PP
\fBTcl_NumUtfChars\fR corresponds to \fBstrlen\fR for UTF-8 strings.  It
returns the number of Tcl_UniChars that are represented by the UTF-8 string
\fIsrc\fR.  The length of the source string is \fIlength\fR bytes.  If the
length is negative, all bytes up to the first null byte are used.
.PP
\fBTcl_UtfFindFirst\fR corresponds to \fBstrchr\fR for UTF-8 strings.  It
returns a pointer to the first occurrence of the Tcl_UniChar \fIch\fR
returns a pointer to the first occurrence of the Unicode character \fIch\fR
in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
considered part of the UTF-8 string.
.PP
\fBTcl_UtfFindLast\fR corresponds to \fBstrrchr\fR for UTF-8 strings.  It
returns a pointer to the last occurrence of the Tcl_UniChar \fIch\fR
returns a pointer to the last occurrence of the Unicode character \fIch\fR
in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
considered part of the UTF-8 string.
.PP
Given \fIsrc\fR, a pointer to some location in a UTF-8 string,
\fBTcl_UtfNext\fR returns a pointer to the next UTF-8 character in the
string.  The caller must not ask for the next character after the last
character in the string if the string is not terminated by a null

return value will be \fIstart\fR.
.PP
\fBTcl_UniCharAtIndex\fR corresponds to a C string array dereference or the
Pascal Ord() function.  It returns the Tcl_UniChar represented at the
specified character (not byte) \fIindex\fR in the UTF-8 string
\fIsrc\fR.  The source string must contain at least \fIindex\fR
characters.  Behavior is undefined if a negative \fIindex\fR is given.
characters.
.PP
\fBTcl_UtfAtIndex\fR returns a pointer to the specified character (not
byte) \fIindex\fR in the UTF-8 string \fIsrc\fR.  The source string must
contain at least \fIindex\fR characters.  This is equivalent to calling
\fBTcl_UtfNext\fR \fIindex\fR times.  If a negative \fIindex\fR is given,
\fBTcl_UtfNext\fR \fIindex\fR times.  If \fIindex\fR is TCL_INDEX_NONE,
the return pointer points to the first character in the source string.
.PP
\fBTcl_UtfBackslash\fR is a utility procedure used by several of the Tcl
commands.  It parses a backslash sequence and stores the properly formed
UTF-8 character represented by the backslash sequence in the output
buffer \fIdst\fR.  At most \fBTCL_UTF_MAX\fR bytes are stored in the buffer.
\fBTcl_UtfBackslash\fR modifies \fI*readPtr\fR to contain the number

.fi
.BE
.SH DESCRIPTION
Abstract classes are classes that can contain definitions, but which cannot be
directly manufactured; they are intended to only ever be inherited from and
instantiated indirectly. The characteristic methods of \fBoo::class\fR
(\fBcreate\fR and \fBnew\fR) are not exported by an instance of
\fBoo::abstract\fR.
.PP
Note that \fBoo::abstract\fR is not itself an instance of \fBoo::abstract\fR.
.SS CONSTRUCTOR
The \fBoo::abstract\fR class does not define an explicit constructor; this
means that it is effectively the same as the constructor of the
\fBoo::class\fR class.
.SS DESTRUCTOR
The \fBoo::abstract\fR class does not define an explicit destructor;
destroying an instance of it is just like destroying an ordinary class (and
will destroy all its subclasses).
.SS "EXPORTED METHODS"
The \fBoo::abstract\fR class defines no new exported methods.
.SS "NON-EXPORTED METHODS"
The \fBoo::abstract\fR class explicitly states that \fBcreate\fR,
\fBcreateWithNamespace\fR, and \fBnew\fR are unexported.
.SH EXAMPLES
.PP
This example defines a simple class hierarchy and creates a new instance of
it. It then invokes a method of the object before destroying the hierarchy and
showing that the destruction is transitive.

.PP
Append all of the \fIvalue\fR arguments to the current value
of variable \fIvarName\fR.  If \fIvarName\fR does not exist,
it is given a value equal to the concatenation of all the

.VS TIP508
If \fIvarName\fR indicate an element that does not exist of an array that has
a default value set, the concatenation of the default value and all the
\fIvalue\fR arguments will be stored in the array element.
.VE TIP508
The result of this command is the new value stored in variable
\fIvarName\fR.
This command provides an efficient way to build up long

\fISearchId\fR indicates which search on \fIarrayName\fR to
check, and must have been the return value from a previous
invocation of \fBarray startsearch\fR.
This option is particularly useful if an array has an element
with an empty name, since the return value from
\fBarray nextelement\fR will not indicate whether the search
has been completed.
.TP
\fBarray default \fIsubcommand arrayName args...\fR
.VS TIP508
Manages the default value of the array. Arrays initially have no default
value, but this command allows you to set one; the default value will be
returned when reading from an element of the array \fIarrayName\fR if the read
would otherwise result in an error. Note that this may cause the \fBappend\fR,
\fBdict\fR, \fBincr\fR and \fBlappend\fR commands to change their behavior in
relation to non-existing array elements.
.RS
.PP
The \fIsubcommand\fR argument controls what exact operation will be performed
on the default value of \fIarrayName\fR. Supported \fIsubcommand\fRs are:
.VE TIP508
.TP
\fBarray default exists \fIarrayName\fR
.VS TIP508
This returns a boolean value indicating whether a default value has been set
for the array \fIarrayName\fR. Returns a false value if \fIarrayName\fR does
not exist. Raises an error if \fIarrayName\fR is an existing variable that is
not an array.
.VE TIP508
.TP
\fBarray default get \fIarrayName\fR
.VS TIP508
This returns the current default value for the array \fIarrayName\fR.  Raises
an error if \fIarrayName\fR is an existing variable that is not an array, or
if \fIarrayName\fR is an array without a default value.
.VE TIP508
.TP
\fBarray default set \fIarrayName value\fR
.VS TIP508
This sets the default value for the array \fIarrayName\fR to \fIvalue\fR.
Returns the empty string. Raises an error if \fIarrayName\fR is an existing
variable that is not an array, or if \fIarrayName\fR is an illegal name for an
array. If \fIarrayName\fR does not currently exist, it is created as an empty
array as well as having its default value set.
.VE TIP508
.TP
\fBarray default unset \fIarrayName\fR
.VS TIP508
This removes the default value for the array \fIarrayName\fR and returns the
empty string. Does nothing if \fIarrayName\fR does not have a default
value. Raises an error if \fIarrayName\fR is an existing variable that is not
an array.
.VE TIP508

.TP
\fBarray donesearch \fIarrayName searchId\fR
This command terminates an array search and destroys all the
state associated with that search.  \fISearchId\fR indicates
which search on \fIarrayName\fR to destroy, and must have
been the return value from a previous invocation of
\fBarray startsearch\fR.  Returns an empty string.
.TP
\fBarray exists \fIarrayName\fR
Returns 1 if \fIarrayName\fR is an array variable, 0 if there
is no variable by that name or if it is a scalar variable.
.TP
\fBarray for {\fIkeyVariable valueVariable\fB} \fIarrayName body\fP
The first argument is a two element list of variable names for the
key and value of each entry in the array.  The second argument is the
array name to iterate over.  The third argument is the body to execute
for each key and value returned.
The ordering of the returned keys is undefined.
If an array element is deleted or a new array element is inserted during
the \fIarray for\fP process, the command will terminate with an error.
.TP
\fBarray get \fIarrayName\fR ?\fIpattern\fR?
Returns a list containing pairs of elements.  The first
element in each pair is the name of an element in \fIarrayName\fR
and the second element of each pair is the value of the
array element.  The order of the pairs is undefined.
If \fIpattern\fR is not specified, then all of the elements of the
array are included in the result.

.SH NAME
callback, mymethod \- generate callbacks to methods
.SH SYNOPSIS
.nf
package require TclOO

\fBcallback\fR \fImethodName\fR ?\fIarg ...\fR?
\fBmymethod\fR \fImethodName\fR ?\fIarg ...\fR?
.fi
.BE
.SH DESCRIPTION
The \fBcallback\fR command,
'\" Based on notes in the tcllib docs, we know the provenance of mymethod
also called \fBmymethod\fR for compatibility with the ooutil and snit packages
of Tcllib,
and which should only be used from within the context of a call to a method
(i.e. inside a method, constructor or destructor body) is used to generate a
script fragment that will invoke the method, \fImethodName\fR, on the current
object (as reported by \fBself\fR) when executed. Any additional arguments
provided will be provided as leading arguments to the callback. The resulting
script fragment shall be a proper list.
.PP
Note that it is up to the caller to ensure that the current object is able to
handle the call of \fImethodName\fR; this command does not check that.
\fImethodName\fR may refer to any exported or unexported method, but may not
refer to a private method as those can only be invoked directly from within
methods. If there is no such method present at the point when the callback is
invoked, the standard \fBunknown\fR method handler will be called.
.SH EXAMPLE
This is a simple echo server class. The \fBcallback\fR command is used in two
places, to arrange for the incoming socket connections to be handled by the
\fIAccept\fR method, and to arrange for the incoming bytes on those
connections to be handled by the \fIReceive\fR method.
.PP

        foreach client [dict keys $clients] {

.SH SYNOPSIS
.nf
package require TclOO

\fBclassvariable\fR \fIvariableName\fR ?\fI...\fR?
.fi
.BE
.SH DESCRIPTION
The \fBclassvariable\fR command is available within methods. It takes a series
of one or more variable names and makes them available in the method's scope;
those variable names must not be qualified and must not refer to array
elements. The originating scope for the variables is the namespace of the
class that the method was defined by. In other words, the referenced variables
are shared between all instances of that class.
.PP
Note: This command is equivalent to the command \fBtypevariable\fR provided by
the snit package in tcllib for approximately the same purpose. If used in a
method defined directly on a class instance (e.g., through the
\fBoo::objdefine\fR \fBmethod\fR definition) this is very much like just
using:
.PP
.CS
namespace upvar [namespace current] $var $var
.CE
.PP
for each variable listed to \fBclassvariable\fR.
.SH EXAMPLE
This class counts how many instances of it have been made.

        puts "This is instance $number of $count"
    }
}

If a format string lacks a \fB%z\fR or \fB%Z\fR format group,
it is possible for the time to be ambiguous because it appears twice
in the same day, once without and once with Daylight Saving Time.
If this situation occurs, the first occurrence of the time is chosen.
(For this reason, it is wise to have the input string contain the
time zone when converting local times.  This caveat does not apply to
UTC times.)
.PP
If the interpretation of the groups yields an impossible time because
a field is out of range, enough of that field's unit will be added to
or subtracted from the time to bring it in range. Thus, if attempting to
scan or format day 0 of the month, one day will be subtracted from day
1 of the month, yielding the last day of the previous month.
.PP
If the interpretation of the groups yields an impossible time because
a Daylight Saving Time change skips over that time, or an ambiguous
time because a Daylight Saving Time change skips back so that the clock
observes the given time twice, and no time zone specifier (\fB%z\fR
or \fB%Z\fR) is present in the format, the time is interpreted as
if the clock had not changed.
.SH "FORMAT GROUPS"
.PP
The following format groups are recognized by the \fBclock scan\fR and
\fBclock format\fR commands.

time.  This is useful for determining the time on a specific day or
doing other date-relative conversions.
.PP
The \fIinputString\fR argument consists of zero or more specifications of the
following form:
.TP
\fItime\fR
.
A time of day, which is of the form: \fBhh?:mm?:ss?? ?meridian? ?zone?\fR
or \fBhhmm ?meridian? ?zone?\fR
If no meridian is specified, \fBhh\fR is interpreted on
A time of day, which is of the form:
.QW "\fIhh\fR?\fB:\fImm\fR?\fB:\fIss\fR?? ?\fImeridian\fR? ?\fIzone\fR?"
or
.QW "\fBhhmm \fR?\fBmeridian\fR? ?\fBzone\fR?" .
If no \fImeridian\fR is specified, \fIhh\fR is interpreted on
a 24-hour clock.
.TP
\fIdate\fR
.
A specific month and day with optional year.  The
acceptable formats are
.QW "\fBmm/dd\fR?\fB/yy\fR?" ,
.QW "\fBmonthname dd\fR?\fB, yy\fR?" ,
.QW "\fBday, dd monthname \fR?\fByy\fR?" ,
.QW "\fBdd monthname yy\fR" ,
.QW "?\fBCC\fR?\fByymmdd\fR" ,
.QW "\fImm\fB/\fIdd\fR?\fB/\fIyy\fR?" ,
.QW "\fImonthname dd\fR?\fB, \fIyy\fR?" ,
.QW "\fIday\fB, \fIdd monthname \fR?\fIyy\fR?" ,
.QW "\fIdd monthname yy\fR" ,
.QW "?\fICC\fR?\fIyymmdd\fR" ,
and
.QW "\fBdd-monthname-\fR?\fBCC\fR?\fByy\fR" .
.QW "\fIdd\fB-\fImonthname\fB-\fR?\fICC\fR?\fIyy\fR" .
The default year is the current year.  If the year is less
than 100, we treat the years 00-68 as 2000-2068 and the years 69-99
as 1969-1999.  Not all platforms can represent the years 38-70, so
an error may result if these years are used.
.TP
\fIISO 8601 point-in-time\fR
.
An ISO 8601 point-in-time specification, such as
.QW \fICCyymmdd\fBT\fIhhmmss\fR,
where \fBT\fR is the literal
.QW T ,
.QW "\fICCyymmdd hhmmss\fR" ,
or
.QW \fICCyymmdd\fBT\fIhh:mm:ss\fR .
.QW \fICCyymmdd\fBT\fIhh\fB:\fImm\fB:\fIss\fR .
Note that only these three formats are accepted.
The command does \fInot\fR accept the full range of point-in-time
specifications specified in ISO8601.  Other formats can be recognized by
giving an explicit \fB\-format\fR option to the \fBclock scan\fR command.
.TP
\fIrelative time\fR
.
A specification relative to the current time.  The format is \fBnumber
unit\fR. Acceptable units are \fByear\fR, \fBfortnight\fR,
\fBmonth\fR, \fBweek\fR, \fBday\fR,
\fBhour\fR, \fBminute\fR (or \fBmin\fR), and \fBsecond\fR (or \fBsec\fR).  The
unit can be specified as a singular or plural, as in \fB3 weeks\fR.
These modifiers may also be specified:
\fBtomorrow\fR, \fByesterday\fR, \fBtoday\fR, \fBnow\fR,

.fi
.SH DESCRIPTION
.PP
The cookiejar package provides an implementation of the http package's cookie
jar protocol using an SQLite database. It provides one main command,
\fB::http::cookiejar\fR, which is a TclOO class that should be instantiated to
create a cookie jar that manages a particular HTTP session.
.PP
The database management policy can be controlled at the package level by the
\fBconfigure\fR method on the \fB::http::cookiejar\fR class object:
.TP
\fB::http::cookiejar configure\fR ?\fIoptionName\fR? ?\fIoptionValue\fR?
.
If neither \fIoptionName\fR nor \fIoptionValue\fR are supplied, this returns a
copy of the configuration as a Tcl dictionary. If just \fIoptionName\fR is
supplied, just the value of the named option is returned. If both
\fIoptionName\fR and \fIoptionValue\fR are given, the named option is changed
to be the given value.
.RS
.PP
Supported options are:
.TP
\fB\-domainfile \fIfilename\fR
.
A file (defaulting to within the cookiejar package) with a description of the
list of top-level domains (e.g., \fB.com\fR or \fB.co.jp\fR). Such domains
\fImust not\fR accept cookies set upon them. Note that the list of such
domains is both security-sensitive and \fInot\fR constant and should be
periodically refetched. Cookie jars maintain their own cache of the domain
list.
.TP
\fB\-domainlist \fIurl\fR
.
A URL to fetch the list of top-level domains (e.g., \fB.com\fR or
\fB.co.jp\fR) from.  Such domains \fImust not\fR accept cookies set upon
them. Note that the list of such domains is both security-sensitive and
\fInot\fR constant and should be periodically refetched. Cookie jars maintain
their own cache of the domain list.
.TP
\fB\-domainrefresh \fIintervalMilliseconds\fR
.
The number of milliseconds between checks of the \fI\-domainlist\fR for new
domains.
.TP
\fB\-loglevel \fIlevel\fR
.
The logging level of this package. The logging level must be (in order of
decreasing verbosity) one of \fBdebug\fR, \fBinfo\fR, \fBwarn\fR, or
\fBerror\fR.
.TP
\fB\-offline \fIflag\fR
.
Allows the cookie managment engine to be placed into offline mode. In offline
mode, the list of domains is read immediately from the file configured in the
\fB\-domainfile\fR option, and the \fB\-domainlist\fR option is not used; it
also makes the \fB\-domainrefresh\fR option be effectively ignored.
.TP
\fB\-purgeold \fIintervalMilliseconds\fR
.
The number of milliseconds between checks of the database for expired
cookies; expired cookies are deleted.
.TP
\fB\-retain \fIcookieCount\fR
.
The maximum number of cookies to retain in the database.
.TP
\fB\-vacuumtrigger \fIdeletionCount\fR
.
A count of the number of persistent cookie deletions to go between vacuuming
the database.
.RE
.PP
Cookie jar instances may be made with any of the standard TclOO instance
creation methods (\fBcreate\fR or \fBnew\fR).
.TP
\fB::http::cookiejar new\fR ?\fIfilename\fR?
.
If a \fIfilename\fR argument is provided, it is the name of a file containing
an SQLite database that will contain the persistent cookies maintained by the
cookie jar; the database will be created if the file does not already
exist. If \fIfilename\fR is not supplied, the database will be held entirely within
memory, which effectively forces all cookies within it to be session cookies.
.SS "INSTANCE METHODS"
.PP
The following methods are supported on the instances:
.TP
\fIcookiejar\fR \fBdestroy\fR
.
This is the standard TclOO destruction method. It does \fInot\fR delete the
SQLite database if it is written to disk. Callers are responsible for ensuring
that the cookie jar is not in use by the http package at the time of
destruction.
.TP
\fIcookiejar\fR \fBforceLoadDomainData\fR
.
This method causes the cookie jar to immediately load (and cache) the domain
list data. The domain list will be loaded from the \fB\-domainlist\fR
configured a the package level if that is enabled, and otherwise will be
obtained from the \fB\-domainfile\fR configured at the package level.
.TP
\fIcookiejar\fR \fBgetCookies\fR \fIprotocol host path\fR
.
This method obtains the cookies for a particular HTTP request. \fIThis
implements the http cookie jar protocol.\fR
.TP
\fIcookiejar\fR \fBpolicyAllow\fR \fIoperation domain path\fR
.
This method is called by the \fBstoreCookie\fR method to get a decision on
whether to allow \fIoperation\fR to be performed for the \fIdomain\fR and
\fIpath\fR. This is checked immediately before the database is updated but
after the built-in security checks are done, and should return a boolean
value; if the value is false, the operation is rejected and the database is
not modified. The supported \fIoperation\fRs are:
.RS
.TP
\fBdelete\fR
.
The \fIdomain\fR is seeking to delete a cookie.
.TP
\fBsession\fR
.
The \fIdomain\fR is seeking to create or update a session cookie.
.TP
\fBset\fR
.
The \fIdomain\fR is seeking to create or update a persistent cookie (with a
defined lifetime).
.PP
The default implementation of this method just returns true, but subclasses of
this class may impose their own rules.
.RE
.TP
\fIcookiejar\fR \fBstoreCookie\fR \fIoptions\fR
.
This method stores a single cookie from a particular HTTP response. Cookies
that fail security checks are ignored. \fIThis implements the http cookie jar
protocol.\fR
.TP
\fIcookiejar\fR \fBlookup\fR ?\fIhost\fR? ?\fIkey\fR?
.
This method looks a cookie by exact host (or domain) matching. If neither
\fIhost\fR nor \fIkey\fR are supplied, the list of hosts for which a cookie is
stored is returned. If just \fIhost\fR (which may be a hostname or a domain
name) is supplied, the list of cookie keys stored for that host is returned.
If both \fIhost\fR and \fIkey\fR are supplied, the value for that key is
returned; it is an error if no such host or key match exactly.
.SH "EXAMPLES"
.PP
The simplest way of using a cookie jar is to just permanently configure it at
the start of the application.
.PP
.CS
package require http
\fBpackage require cookiejar\fR

set cookiedb ~/.tclcookies.db
http::configure -cookiejar [\fBhttp::cookiejar new\fR $cookiedb]

# No further explicit steps are required to use cookies
set tok [http::geturl http://core.tcl.tk/]
.CE
.PP
To only allow a particular domain to use cookies, perhaps because you only
want to enable a particular host to create and manipulate sessions, create a
subclass that imposes that policy.
.PP
.CS
package require http
\fBpackage require cookiejar\fR

oo::class create MyCookieJar {
    superclass \fBhttp::cookiejar\fR

    method \fBpolicyAllow\fR {operation domain path} {
        return [expr {$domain eq "my.example.com"}]
    }
}

set cookiedb ~/.tclcookies.db
http::configure -cookiejar [MyCookieJar new $cookiedb]

# No further explicit steps are required to use cookies

of the context can then be resumed by calling the context command, optionally
passing in the \fIsingle\fR value to use as the result of the \fByield\fR call
that caused
the context to be suspended. If the coroutine context never yields and instead
returns conventionally, the result of the \fBcoroutine\fR command will be the
result of the evaluation of the context.
.PP
.VS TIP396
The coroutine may also suspend its execution by use of the \fByieldto\fR
command, which instead of returning, cedes execution to some command called
\fIcommand\fR (resolved in the context of the coroutine) and to which \fIany
number\fR of arguments may be passed. Since every coroutine has a context
command, \fByieldto\fR can be used to transfer control directly from one
coroutine to another (this is only advisable if the two coroutines are
expecting this to happen) but \fIany\fR command may be the target. If a
coroutine is suspended by this mechanism, the coroutine processing can be
resumed by calling the context command optionally passing in an arbitrary
number of arguments. The return value of the \fByieldto\fR call will be the
list of arguments passed to the context command; it is up to the caller to
decide what to do with those values.
.PP
The recommended way of writing a version of \fByield\fR that allows resumption
with multiple arguments is by using \fByieldto\fR and the \fBreturn\fR
command, like this:
.PP
.CS
proc yieldm {value} {
    \fByieldto\fR return -level 0 $value
proc yieldMultiple {value} {
    tailcall \fByieldto\fR string cat $value
}
.CE
.VE TIP396
.PP
The coroutine can also be deleted by destroying the command \fIname\fR, and
the name of the current coroutine can be retrieved by using
\fBinfo coroutine\fR.
If there are deletion traces on variables in the coroutine's
implementation, they will fire at the point when the coroutine is explicitly
deleted (or, naturally, if the command returns conventionally).
.PP
At the point when \fIcommand\fR is called, the current namespace will be the
global namespace and there will be no stack frames above it (in the sense of
\fBupvar\fR and \fBuplevel\fR). However, which command to call will be
determined in the namespace that the \fBcoroutine\fR command was called from.
.PP
.VS "8.7, TIP383"
A suspended coroutine (i.e., one that has \fByield\fRed or \fByieldto\fR-d)
may have its state inspected (or modified) at that point by using
\fBcoroprobe\fR to run a command at the point where the coroutine is at. The
command takes the name of the coroutine to run the command in, \fIcoroName\fR,
and the name of a command (any any arguments it requires) to immediately run
at that point. The result of that command is the result of the \fBcoroprobe\fR
command, and the gross state of the coroutine remains the same afterwards
(i.e., the coroutine is still expecting the results of a \fByield\fR or
\fByieldto\fR as before) though variables may have been changed.
.PP
Similarly, the \fBcoroinject\fR command may be used to place a command to be
run inside a suspended coroutine (when it is resumed) to process arguments,
with quite a bit of similarity to \fBcoroprobe\fR. However, with
\fBcoroinject\fR there are several key differences:
.VE "8.7, TIP383"
.IP \(bu
.VS "8.7, TIP383"
The coroutine is not immediately resumed after the injection has been done.  A
consequence of this is that multiple injections may be done before the
coroutine is resumed. There injected commands are performed in \fIreverse
order of definition\fR (that is, they are internally stored on a stack).
.VE "8.7, TIP383"
.IP \(bu
.VS "8.7, TIP383"
An additional two arguments are appended to the list of arguments to be run
(that is, the \fIcommand\fR and its \fIargs\fR are extended by two elements).
The first is the name of the command that suspended the coroutine (\fByield\fR
or \fByieldto\fR), and the second is the argument (or list of arguments, in
the case of \fByieldto\fR) that is the current resumption value.
.VE "8.7, TIP383"
.IP \(bu
.VS "8.7, TIP383"
The result of the injected command is used as the result of the \fByield\fR or
\fByieldto\fR that caused the coroutine to become suspended. Where there are
multiple injected commands, the result of one becomes the resumption value
processed by the next.
.PP
The injection is a one-off. It is not retained once it has been executed. It
may \fByield\fR or \fByieldto\fR as part of its execution.
.PP
Note that running coroutines may be neither probed nor injected; the
operations may only be applied to
.VE "8.7, TIP383"

even values, and a loop that consumes the first ten of them.

configuration of all subclasses of the class and all objects that are
instances of that class or which mix it in (as modified by any per-instance
configuration). The way in which the configuration is done is controlled by
either the \fIdefScript\fR argument or by the \fIsubcommand\fR and following
\fIarg\fR arguments; when the second is present, it is exactly as if all the
arguments from \fIsubcommand\fR onwards are made into a list and that list is
used as the \fIdefScript\fR argument.
.PP
Note that the constructor for \fBoo::class\fR will call \fBoo::define\fR on
the script argument that it is provided. This is a convenient way to create
and define a class in one step.

.PP
The following commands are supported in the \fIdefScript\fR for
\fBoo::define\fR, each of which may also be used in the \fIsubcommand\fR form:
.TP
\fBclassmethod\fI name\fR ?\fIargList bodyScrip\fR?
.VS TIP478
This creates a class method, or (if \fIargList\fR and \fIbodyScript\fR are
omitted) promotes an existing method on the class object to be a class
method. The \fIname\fR, \fIargList\fR and \fIbodyScript\fR arguments are as in
the \fBmethod\fR definition, below.
.RS
.PP
Class methods can be called on either the class itself or on the instances of
that class. When they are called, the current object (see the \fBsel\fR and
\fBmy\fR commands) is the class on which they are called or the class of the
instance on which they are called, depending on whether they are called on the
class or an instance of the class, respectively. If called on a subclass or
instance of the subclass, the current object is the subclass.
.PP
In a private definition context, the methods as invoked on classes are
\fInot\fR private, but the methods as invoked on instances of classes are
private.
.RE
.VE TIP478
.TP
\fBconstructor\fI argList bodyScript\fR
.
This creates or updates the constructor for a class. The formal arguments to
the constructor (defined using the same format as for the Tcl \fBproc\fR
command) will be \fIargList\fR, and the body of the constructor will be
\fIbodyScript\fR. When the body of the constructor is evaluated, the current
namespace of the constructor will be a namespace that is unique to the object
being constructed. Within the constructor, the \fBnext\fR command should be
used to call the superclasses' constructors. If \fIbodyScript\fR is the empty
string, the constructor will be deleted.
.TP
.RS
\fBdeletemethod\fI name\fR ?\fIname ...\fR
.
.PP
This deletes each of the methods called \fIname\fR from a class. The methods
must have previously existed in that class. Does not affect the superclasses
Classes do not need to have a constructor defined. If none is specified, the
superclass's constructor will be used instead.

\fBdestructor\fI bodyScript\fR

This creates or updates the destructor for a class. Destructors take no
arguments, and the body of the destructor will be \fIbodyScript\fR. The
destructor is called when objects of the class are deleted, and when called
will have the object's unique namespace as the current namespace. Destructors

\fBexport\fI name \fR?\fIname ...\fR?
.
This arranges for each of the named methods, \fIname\fR, to be exported
(i.e. usable outside an instance through the instance object's command) by the
class being defined. Note that the methods themselves may be actually defined
by a superclass; subclass exports override superclass visibility, and may in
turn be overridden by instances.
.TP
\fBfilter\fR ?\fI\-slotOperation\fR? ?\fImethodName ...\fR?
.VS
This slot (see \fBSLOTTED DEFINITIONS\fR below)
.VE
sets or updates the list of method names that are used to guard whether
method call to instances of the class may be called and what the method's
results are. Each \fImethodName\fR names a single filtering method (which may
be exposed or not exposed); it is not an error for a non-existent method to be
named since they may be defined by subclasses.
.VS
By default, this slot works by appending.
.VE
.TP
\fBforward\fI name cmdName \fR?\fIarg ...\fR?
.
This creates or updates a forwarded method called \fIname\fR. The method is
defined be forwarded to the command called \fIcmdName\fR, with additional
arguments, \fIarg\fR etc., added before those arguments specified by the
caller of the method. The \fIcmdName\fR will always be resolved using the
rules of the invoking objects' namespaces, i.e., when \fIcmdName\fR is not
fully-qualified, the command will be searched for in each object's namespace,
using the instances' namespace's path, or by looking in the global namespace.
The method will be exported if \fIname\fR starts with a lower-case letter, and
non-exported otherwise.

itself. This is useful for setting up, e.g., class-scoped variables.
.VE TIP478
.TP
\fBmethod\fI name argList bodyScript\fR
\fBmethod\fI name \fR?\fIoption\fR? \fIargList bodyScript\fR
.
This creates or updates a method that is implemented as a procedure-like
script. The name of the method is \fIname\fR, the formal arguments to the
method (defined using the same format as for the Tcl \fBproc\fR command) will
be \fIargList\fR, and the body of the method will be \fIbodyScript\fR. When
the body of the method is evaluated, the current namespace of the method will
be a namespace that is unique to the current object. The method will be
exported if \fIname\fR starts with a lower-case letter, and non-exported
otherwise; this behavior can be overridden via \fBexport\fR and
\fBunexport\fR.

sets or updates the list of additional classes that are to be mixed into
all the instances of the class being defined. Each \fIclassName\fR argument
names a single class that is to be mixed in.

method must have previously existed in the class, and \fItoName\fR must not
previously refer to a method in that class. Does not affect the superclasses

(except when they have a call chain through the class being modified). Does
not change the export status of the method; if it was exported before, it will
be afterwards.
.RS
.PP
The following class definition commands are affected by \fBprivate\fR:
\fBforward\fR, \fBmethod\fR, \fBself\fR, and \fBvariable\fR. Nesting
\fBprivate\fR inside \fBprivate\fR has no cumulative effect; the innermost
definition context is just a private definition context. All other definition
commands have no difference in behavior when used in a private definition
context.

.VE
allows the alteration of the superclasses of the class being defined.
Each \fIclassName\fR argument names one class that is to be a superclass of
the defined class. Note that objects must not be changed from being classes to
being non-classes or vice-versa, that an empty parent class is equivalent to
\fBoo::object\fR, and that the parent classes of \fBoo::object\fR and
\fBoo::class\fR may not be modified.

By default, this slot works by replacement.

.TP
\fBunexport\fI name \fR?\fIname ...\fR?

This arranges for each of the named methods, \fIname\fR, to be not exported
(i.e. not usable outside the instance through the instance object's command,
but instead just through the \fBmy\fR command visible in each object's
context) by the class being defined. Note that the methods themselves may be
actually defined by a superclass; subclass unexports override superclass
visibility, and may be overridden by instance unexports.
.TP
\fBvariable\fR ?\fI\-slotOperation\fR? ?\fIname ...\fR?
.VS
.
This slot (see \fBSLOTTED DEFINITIONS\fR below) arranges for each of the named
variables to be automatically made
available in the methods, constructor and destructor declared by the class
being defined. Each variable name must not have any namespace
separators and must not look like an array access. All variables will be
actually present in the namespace of the instance object on which the method
actually present in the instance object on which the method is executed. Note
is executed. Note
that the variable lists declared by a superclass or subclass are completely
disjoint, as are variable lists declared by instances; the list of variable
names is just for methods (and constructors and destructors) declared by this
class. By default, this slot works by appending.
.RS
.PP
.VS TIP500
If in a private definition context (see the \fBprivate\fR definition command,
below), this slot manipulates the list of private variable bindings for this
class. In a private variable binding, the name of the variable within the
instance object is different to the name given in the definition; the name
used in the definition is the name that you use to access the variable within
the methods of this class, and the name of the variable in the instance
namespace has a unique prefix that makes accidental use from other classes
extremely unlikely.

The following definitions are also supported, but are not required in simple

\fBdefinitionnamespace\fR ?\fIkind\fR? \fInamespaceName\fR
.VS TIP524
This allows control over what namespace will be used by the \fBoo::define\fR
and \fBoo::objdefine\fR commands to look up the definition commands they
use. When any object has a definition operation applied to it, \fIthe class that
it is an instance of\fR (and its superclasses and mixins) is consulted for
what definition namespace to use. \fBoo::define\fR gets the class definition
namespace, and \fB::oo::objdefine\fR gets the instance definition namespace,
but both otherwise use the identical lookup operation.
.RS
.PP
This sets the definition namespace of kind \fIkind\fR provided by the current
class to \fInamespaceName\fR. The \fInamespaceName\fR must refer to a
currently existing namespace, or must be the empty string (to stop the current
class from having such a namespace connected). The \fIkind\fR, if supplied,
must be either \fB\-class\fR (the default) or \fB\-instance\fR to specify the
whether the namespace for use with \fBoo::define\fR or \fBoo::objdefine\fR
respectively is being set.
.PP
The class \fBoo::object\fR has its instance namespace locked to
\fB::oo::objdefine\fR, and the class \fBoo::class\fR has its class namespace
locked to \fB::oo::define\fR. A consequence of this is that effective use of
this feature for classes requires the definition of a metaclass.

This deletes each of the methods called \fIname\fR from a class. The methods

of the class, nor does it affect the subclasses or instances of the class
(except when they have a call chain through the class being modified) or the

This slot (see \fBSLOTTED DEFINITIONS\fR below)
sets or updates the list of method names that are used to guard whether
method call to instances of the class may be called and what the method's
results are. Each \fImethodName\fR names a single filtering method (which may
be exposed or not exposed); it is not an error for a non-existent method to be
named since they may be defined by subclasses.

names a single class that is to be mixed in.
By default, this slot works by replacement.

\fBrenamemethod\fI fromName toName\fR
.
This renames the method called \fIfromName\fR in a class to \fItoName\fR. The
method must have previously existed in the class, and \fItoName\fR must not
previously refer to a method in that class. Does not affect the superclasses
of the class, nor does it affect the subclasses or instances of the class

A consequence of this is that any use of a slot's default operation where the
first member argument begins with a hyphen will be an error. One of the above
operations should be used explicitly in those circumstances.

Internally, slot objects also define a method \fB\-\-default\-operation\fR

does nothing, whereas for slots of classes, this maps a class name to its
fully-qualified class name.  This method must always be called from a stack
frame created by a call to \fBoo::define\fR or \fBoo::objdefine\fR.  This

of classes enforce a uniqueness constraint that places each element in the
earliest location in the slot that it can.)
.RE
.PP
The implementation of these methods is slot-dependent (and responsible for
accessing the correct part of the class or object definition). Slots also have
an unknown method handler to tie all these pieces together, and they hide
their \fBdestroy\fR method so that it is not invoked inadvertently. It is
\fIrecommended\fR that any user changes to the slot mechanism be restricted to
defining new operations whose names start with a hyphen.
.PP
.VS TIP516
Most slot operations will initially \fBResolve\fR their argument list, combine
it with the results of the \fBGet\fR method, and then \fBSet\fR the result.
Some operations omit one or both of the first two steps; omitting the third
would result in an idempotent read-only operation (but the standard mechanism
for reading from slots is via \fBinfo class\fR and \fBinfo object\fR).

Note that the current escape resp. quoting of arguments for windows works only
with executables using CommandLineToArgv, CRT-library or similar, as well as
with the windows batch files (excepting the newline, see below).
Although it is the common escape algorithm, but, in fact, the way how the
executable parses the command-line (resp. splits it into single arguments)
is decisive.
.PP
Unfortunately, there is currently no way to supply newline character within
an argument to the batch files (\fB.cmd\fR or \fB.bat\fR) or to the command
processor (\fBcmd.exe /c\fR), because this causes truncation of command-line
(also the argument chain) on the first newline character.

The exponentiation operator promotes types in the same way that the multiply

\fBpow\fR.
Exponentiation groups right-to-left within a precedence level. Other binary

substitutions on, enclosing an expression in braces or otherwise quoting it
so that it's a static value allows the Tcl compiler to generate bytecode for
the expression, resulting in better speed and smaller storage requirements.
This also avoids issues that can arise if Tcl is allowed to perform
substitution on the value before \fBexpr\fR is called.
.PP
In the following example, the value of the expression is 11 because the Tcl parser first
substitutes \fB$b\fR and \fBexpr\fR then substitutes \fB$a\fR.  Enclosing the
expression in braces would result in a syntax error.
substitutes \fB$b\fR and \fBexpr\fR then substitutes \fB$a\fR as part
of evaluating the expression
.QW "$a + 2*4" .
Enclosing the
expression in braces would result in a syntax error as \fB$b\fR does
not evaluate to a numeric value.

.CS

.CE

When an expression is generated at runtime, like the one above is, the bytcode
When an expression is generated at runtime, like the one above is, the bytecode
compiler must ensure that new code is generated each time the expression
is evaluated.  This is the most costly kind of expression from a performance
perspective.  In such cases, consider directly using the commands described in
the \fBmathfunc\fR(n) or \fBmathop\fR(n) documentation instead of \fBexpr\fR.

.PP
Most expressions are not formed at runtime, but are literal strings or contain
substitutions that don't introduce other substitutions.  To allow the bytecode
compiler to work with an expression as a string literal at compilation time,
ensure that it contains no substitutions or that it is enclosed in braces or
otherwise quoted to prevent Tcl from performing substitutions, allowing
\fBexpr\fR to perform them instead.
.PP
If it is necessary to include a non-constant expression string within the
wider context of an otherwise-constant expression, the most efficient
technique is to put the varying part inside a recursive \fBexpr\fR, as this at
least allows for the compilation of the outer part, though it does mean that
the varying part must itself be evaluated as a separate expression. Thus, in
this example the result is 20 and the outer expression benefits from fully
cached bytecode compilation.
.PP
.CS
set a 3
set b {$a + 2}
\fBexpr\fR {[\fBexpr\fR $b] * 4}
.CE
.PP
In general, you should enclose your expression in braces wherever possible,
and where not possible, the argument to \fBexpr\fR should be an expression
defined elsewhere as simply as possible. It is usually more efficient and
safer to use other techniques (e.g., the commands in the \fBtcl::mathop\fR
namespace) than it is to do complex expression generation.

.PP
The \fBhttp\fR package provides the client side of the HTTP/1.1
protocol, as defined in RFC 2616.
protocol, as defined in RFC 7230 to RFC 7235, which supersede RFC 2616.
The package implements the GET, POST, and HEAD operations
of HTTP/1.1.  It allows configuration of a proxy host to get through
firewalls.  The package is compatible with the \fBSafesock\fR security
policy, so it can be used by untrusted applets to do URL fetching from
a restricted set of hosts. This package can be extended to support
additional HTTP transport protocols, such as HTTPS, by providing
a custom \fBsocket\fR command, via \fB::http::register\fR.

to determine if a proxy is required for a given host.  One argument, a
host name, is added to \fIcommand\fR when it is invoked.  If a proxy
is required, the callback should return a two-element list containing
the proxy server and proxy port.  Otherwise the filter should return
an empty list.  The default filter returns the values of the
\fB\-proxyhost\fR and \fB\-proxyport\fR settings if they are
non-empty.
.TP
\fB\-repost\fR \fIboolean\fR
.
Specifies what to do if a POST request over a persistent connection fails
because the server has half-closed the connection.  If boolean \fBtrue\fR, the
request
will be automatically retried; if boolean \fBfalse\fR it will not, and the
application
that uses \fBhttp::geturl\fR is expected to seek user confirmation before
retrying the POST.  The value \fBtrue\fR should be used only under certain
conditions. See the \fBPERSISTENT SOCKETS\fR section for details. The
default is 0.

\fB::http::formatQuery\fR and \fB::http::quoteString\fR.
\fB::http::formatQuery\fR.  The default is \fButf-8\fR, as specified by RFC
The default is \fButf-8\fR, as specified by RFC
2718.  Prior to http 2.5 this was unspecified, and that behavior can be
returned by specifying the empty string (\fB{}\fR), although
\fIiso8859-1\fR is recommended to restore similar behavior but without the

characters.
\fB::http::formatQuery\fR or \fB::http::quoteString\fR
throwing an error processing non-latin-1 characters.
.TP
\fB\-useragent\fR \fIstring\fR
.
The value of the User-Agent header in the HTTP request.  The default is
.QW "\fBTcl http client package 2.7\fR" .
The value of the User-Agent header in the HTTP request.  In an unsafe
interpreter, the default value depends upon the operating system, and
the version numbers of \fBhttp\fR and \fBTcl\fR, and is (for example)
.QW "\fBMozilla/5.0 (Windows; U; Windows NT 10.0) http/2.8.12 Tcl/8.6.8\fR" .
A safe interpreter cannot determine its operating system, and so the default
in a safe interpreter is to use a Windows 10 value with the current version
numbers of \fBhttp\fR and \fBTcl\fR.
.TP
\fB\-zip\fR \fIboolean\fR
.
If the value is boolean \fBtrue\fR, then by default requests will send a header
.QW "\fBAccept-Encoding: gzip,deflate,compress\fR" .
If the value is boolean \fBfalse\fR, then by default this header will not be sent.
In either case the default can be overridden for an individual request by
supplying a custom \fBAccept-Encoding\fR header in the \fB-headers\fR option
of \fBhttp::geturl\fR. The default is 1.
.RE
.TP
\fB::http::geturl\fR \fIurl\fR ?\fIoptions\fR?
.
The \fB::http::geturl\fR command is the main procedure in the package.
The \fB\-query\fR option causes a POST operation and
the \fB\-validate\fR option causes a HEAD operation;

.TP
\fBurl\fR

The requested URL.
.RE
.SH "PERSISTENT CONNECTIONS"
.PP
.SS "BASICS"
.PP
See RFC 7230 Sec 6, which supersedes RFC 2616 Sec 8.1.
.PP
A persistent connection allows multiple HTTP/1.1 transactions to be
carried over the same TCP connection.  Pipelining allows a
client to make multiple requests over a persistent connection without
waiting for each response.  The server sends responses in the same order
that the requests were received.
.PP
If a POST request fails to complete, typically user confirmation is
needed before sending the request again.  The user may wish to verify
whether the server was modified by the failed POST request, before
sending the same request again.
.PP
A HTTP request will use a persistent socket if the call to
\fBhttp::geturl\fR has the option \fB-keepalive true\fR. It will use
pipelining where permitted if the \fBhttp::config\fR option
\fB-pipeline\fR is boolean \fBtrue\fR (its default value).
.PP
The http package maintains no more than one persistent connection to each
server (i.e. each value of
.QW "domain:port" ).
If \fBhttp::geturl\fR is called to make a request over a persistent
connection while the connection is busy with another request, the new
request will be held in a queue until the connection is free.
.PP
The http package does not support HTTP/1.0 persistent connections
controlled by the \fBKeep-Alive\fR header.
.SS "SPECIAL CASES"
.PP
This subsection discusses issues related to closure of the
persistent connection by the server, automatic retry of failed requests,
the special treatment necessary for POST requests, and the options for
dealing with these cases.
.PP
In accordance with RFC 7230, \fBhttp::geturl\fR does not pipeline
requests that use the POST method.  If a POST uses a persistent
connection and is not the first request on that connection,
\fBhttp::geturl\fR waits until it has received the response for the previous
request; or (if \fBhttp::config\fR option \fB-postfresh\fR is boolean \fBtrue\fR) it
uses a new connection for each POST.
.PP
If the server is processing a number of pipelined requests, and sends a
response header
.QW "\fBConnection: close\fR"
with one of the responses (other than the last), then subsequent responses
are unfulfilled. \fBhttp::geturl\fR will send the unfulfilled requests again
over a new connection.
.PP
A difficulty arises when a HTTP client sends a request over a persistent
connection that has been idle for a while.  The HTTP server may
half-close an apparently idle connection while the client is sending a
request, but before the request arrives at the server: in this case (an
.QW "asynchronous close event" )
the request will fail.  The difficulty arises because the client cannot
be certain whether the POST modified the state of the server.  For HEAD or
GET requests, \fBhttp::geturl\fR opens another connection and retransmits
the failed request. However, if the request was a POST, RFC 7230 forbids
automatic retry by default, suggesting either user confirmation, or
confirmation by user-agent software that has semantic understanding of
the application.  The \fBhttp::config\fR option \fB-repost\fR allows for
either possibility.
.PP
Asynchronous close events can occur only in a short interval of time.  The
\fBhttp\fR package monitors each persistent connection for closure by the
server.  Upon detection, the connection is also closed at the client end,
and subsequent requests will use a fresh connection.
.PP
If the \fBhttp::geturl\fR command is called with option \fB-keepalive true\fR,
then it will both try to use an existing persistent connection
(if one is available), and it will send the server a
.QW "\fBConnection: keep-alive\fR"
request header asking to keep the connection open for future requests.
.PP
The \fBhttp::config\fR options \fB-pipeline\fR, \fB-postfresh\fR, and
\fB-repost\fR relate to persistent connections.
.PP
Option \fB-pipeline\fR, if boolean \fBtrue\fR, will pipeline GET and HEAD requests
made
over a persistent connection.  POST requests will not be pipelined - if the
POST is not the first transaction on the connection, its request will not
be sent until the previous response has finished.  GET and HEAD requests
made after a POST will not be sent until the POST response has been
delivered, and will not be sent if the POST fails.
.PP
Option \fB-postfresh\fR, if boolean \fBtrue\fR, will override the \fBhttp::geturl\fR option
\fB-keepalive\fR, and always open a fresh connection for a POST request.
.PP
Option \fB-repost\fR, if \fBtrue\fR, permits automatic retry of a POST request
that fails because it uses a persistent connection that the server has
half-closed (an
.QW "asynchronous close event" ).
Subsequent GET and HEAD requests in a failed pipeline will also be retried.
\fIThe -repost option should be used only if the application understands
that the retry is appropriate\fR - specifically, the application must know
that if the failed POST successfully modified the state of the server, a repeat POST
would have no adverse effect.
.VS TIP406
.SH "COOKIE JAR PROTOCOL"
.PP
Cookies are short key-value pairs used to implement sessions within the
otherwise-stateless HTTP protocol. (See RFC 6265 for details; Tcl does not
implement the Cookie2 protocol as that is rarely seen in the wild.)
.PP
Cookie storage managment commands \(em
.QW "cookie jars"
\(em must support these subcommands which form the HTTP cookie storage
management protocol. Note that \fIcookieJar\fR below does not have to be a
command name; it is properly a command prefix (a Tcl list of words that will
be expanded in place) and admits many possible implementations.
.PP
Though not formally part of the protocol, it is expected that particular
values of \fIcookieJar\fR will correspond to sessions; it is up to the caller
of \fB::http::config\fR to decide what session applies and to manage the
deletion of said sessions when they are no longer desired (which should be
when they not configured as the current cookie jar).
.TP
\fIcookieJar \fBgetCookies \fIprotocol host requestPath\fR
.
This command asks the cookie jar what cookies should be supplied for a
particular request. It should take the \fIprotocol\fR (typically \fBhttp\fR or
\fBhttps\fR), \fIhost\fR name and \fIrequestPath\fR (parsed from the \fIurl\fR
argument to \fB::http::geturl\fR) and return a list of cookie keys and values
that describe the cookies to supply to the remote host. The list must have an
even number of elements.
.RS
.PP
There should only ever be at most one cookie with a particular key for any
request (typically the one with the most specific \fIhost\fR/domain match and
most specific \fIrequestPath\fR/path match), but there may be many cookies
with different names in any request.
.RE
.TP
\fIcookieJar \fBstoreCookie \fIcookieDictionary\fR
.
This command asks the cookie jar to store a particular cookie that was
returned by a request; the result of this command is ignored. The cookie
(which will have been parsed by the http package) is described by a
dictionary, \fIcookieDictionary\fR, that may have the following keys:
.RS
.TP
\fBdomain\fR
.
This is always present. Its value describes the domain hostname \fIor
prefix\fR that the cookie should be returned for.  The checking of the domain
against the origin (below) should be careful since sites that issue cookies
should only do so for domains related to themselves. Cookies that do not obey
a relevant origin matching rule should be ignored.
.TP
\fBexpires\fR
.
This is optional. If present, the cookie is intended to be a persistent cookie
and the value of the option is the Tcl timestamp (in seconds from the same
base as \fBclock seconds\fR) of when the cookie expires (which may be in the
past, which should result in the cookie being deleted immediately). If absent,
the cookie is intended to be a session cookie that should be not persisted
beyond the lifetime of the cookie jar.
.TP
\fBhostonly\fR
.
This is always present. Its value is a boolean that describes whether the
cookie is a single host cookie (true) or a domain-level cookie (false).
.TP
\fBhttponly\fR
.
This is always present. Its value is a boolean that is true when the site
wishes the cookie to only ever be used with HTTP (or HTTPS) traffic.
.TP
\fBkey\fR
.
This is always present. Its value is the \fIkey\fR of the cookie, which is
part of the information that must be return when sending this cookie back in a
future request.
.TP
\fBorigin\fR
.
This is always present. Its value describes where the http package believes it
received the cookie from, which may be useful for checking whether the
cookie's domain is valid.
.TP
\fBpath\fR
.
This is always present. Its value describes the path prefix of requests to the
cookie domain where the cookie should be returned.
.TP
\fBsecure\fR
.
This is always present. Its value is a boolean that is true when the cookie
should only used on requests sent over secure channels (typically HTTPS).
.TP
\fBvalue\fR
.
This is always present. Its value is the value of the cookie, which is part of
the information that must be return when sending this cookie back in a future
request.
.PP
Other keys may always be ignored; they have no meaning in this protocol.

.SH DESCRIPTION
This package provides an implementation of the punycode scheme used in
Internationalised Domain Names, and some access commands. (See RFC 3492 for a
description of punycode.)
.TP
\fBtcl::idna decode\fR \fIhostname\fR
.
This command takes the name of a host that potentially contains
punycode-encoded character sequences, \fIhostname\fR, and returns the hostname
as might be displayed to the user. Note that there are often UNICODE
characters that have extremely similar glyphs, so care should be taken with
displaying hostnames to users.
.TP
\fBtcl::idna encode\fR \fIhostname\fR
.
This command takes the name of a host as might be displayed to the user,
\fIhostname\fR, and returns the version of the hostname with characters not
permitted in basic hostnames encoded with punycode.
.TP
\fBtcl::idna puny\fR \fIsubcommand ...\fR
.
This command provides direct access to the basic punycode encoder and
decoder. It supports two \fIsubcommand\fRs:
.RS
.TP
\fBtcl::idna puny decode\fR \fIstring\fR ?\fIcase\fR?
.
This command decodes the punycode-encoded string, \fIstring\fR, and returns
the result. If \fIcase\fR is provided, it is a boolean to make the case be
folded to upper case (if \fIcase\fR is true) or lower case (if \fIcase\fR is
false) during the decoding process; if omitted, no case transformation is
applied.
.TP
\fBtcl::idna puny encode\fR \fIstring\fR ?\fIcase\fR?
.
This command encodes the string, \fIstring\fR, and returns the
punycode-encoded version of the string. If \fIcase\fR is provided, it is a
boolean to make the case be folded to upper case (if \fIcase\fR is true) or
lower case (if \fIcase\fR is false) during the encoding process; if omitted,
no case transformation is applied.
.RE
.TP
\fBtcl::idna version\fR
.
This returns the version of the \fBtcl::idna\fR package.
.SH "EXAMPLE"
.PP
This is an example of how punycoding of a string works:
.PP
.CS
package require tcl::idna

puts [\fBtcl::idna puny encode\fR "abc\(->def"]
#    prints: \fIabcdef-kn2c\fR
puts [\fBtcl::idna puny decode\fR "abcdef-kn2c"]

usually the unsubstituted form, however for commands which are a
canonically-constructed list (e.g., as produced by the \fBlist\fR command)

string representation. Care is taken that the canonicality property of
the latter is not spoiled.

A thing of note is that for procedures statically defined in files the

When a command can be traced to its literal definition in some script, e.g.
\fBsource\fR and absolute line numbers, and not as type

defined procedures, and literal eval scripts in files or statically
defined procedures.

files or statically defined procedures, its type is \fBsource\fR and its
location is the absolute line number in the script.  Otherwise, its type is
\fBproc\fR and its location is its line number within the body of the
procedure.
.PP
In contrast, procedure definitions and \fBeval\fR within a dynamically
\fBeval\fRuated environment count line numbers relative to the start of
their script, even if they would be able to count relative to the
start of the outer dynamic script. That type of number usually makes
more sense.
.PP
A different way of describing this behaviour is that file based
A different way of describing this behaviour is that file-based
locations are tracked as deeply as possible, and where this is not
possible the lines are counted based on the smallest possible
\fBeval\fR or procedure body, as that scope is usually easier to find
than any dynamic outer scope.
.PP
The syntactic form \fB{*}\fR is handled like \fBeval\fR. I.e. if it
is given a literal list argument the system tracks the line number
within the list words as well, and otherwise all line numbers are
counted relative to the start of each word (smallest scope)

.SH DESCRIPTION
.PP
This command treats the variable given by \fIvarName\fR as a list
and appends each of the \fIvalue\fR arguments to that list as a separate
element, with spaces between elements.
If \fIvarName\fR does not exist, it is created as a list with elements
given by the \fIvalue\fR arguments.
.VS TIP508
If \fIvarName\fR indicate an element that does not exist of an array that has
a default value set, list that is comprised of the default value with all the
\fIvalue\fR arguments appended as elements will be stored in the array
element.
.VE TIP508
\fBLappend\fR is similar to \fBappend\fR except that the \fIvalue\fRs
are appended as list elements rather than raw text.
This command provides a relatively efficient way to build up
large lists.  For example,
.QW "\fBlappend a $b\fR"
is much more efficient than
.QW "\fBset a [concat $a [list $b]]\fR"

.TH link n 0.3 TclOO "TclOO Commands"
.so man.macros
.BS
'\" Note:  do not modify the .SH NAME line immediately below!
.SH NAME
link \- create link from command to method of object
.SH SYNOPSIS
.nf
package require TclOO

\fBlink\fR \fImethodName\fR ?\fI...\fR?
\fBlink\fR \fB{\fIcommandName methodName\fB}\fR ?\fI...\fR?
.fi
.BE
.SH DESCRIPTION
The \fBlink\fR command is available within methods. It takes a series of one
or more method names (\fImethodName ...\fR) and/or pairs of command- and
method-name (\fB{\fIcommandName methodName\fB}\fR) and makes the named methods
available as commands without requiring the explicit use of the name of the
object or the \fBmy\fR command. The method does not need to exist at the time
that the link is made; if the link command is invoked when the method does not
exist, the standard \fBunknown\fR method handling system is used.
.PP
The command name under which the method becomes available defaults to the
method name, except where explicitly specified through an alias/method pair.
Formally, every argument must be a list; if the list has two elements, the
first element is the name of the command to create and the second element is
the name of the method of the current object to which the command links;
otherwise, the name of the command and the name of the method are the same
string (the first element of the list).
.PP
If the name of the command is not a fully-qualified command name, it will be
resolved with respect to the current namespace (i.e., the object namespace).
.SH EXAMPLES
This demonstrates linking a single method in various ways. First it makes a
simple link, then a renamed link, then an external link. Note that the method
itself is unexported, but that it can still be called directly from outside
the class.
.PP
.CS
oo::class create ABC {
    method Foo {} {
        puts "This is Foo in [self]"
    }

    constructor {} {
        \fBlink\fR Foo
        # The method foo is now directly accessible as foo here
        \fBlink\fR {bar Foo}
        # The method foo is now directly accessible as bar
        \fBlink\fR {::ExternalCall Foo}
        # The method foo is now directly accessible in the global
        # namespace as ExternalCall
    }

    method grill {} {
        puts "Step 1:"
        Foo
        puts "Step 2:"
        bar
    }
}

ABC create abc
abc grill
        \fI\(-> Step 1:\fR
        \fI\(-> This is foo in ::abc\fR
        \fI\(-> Step 2:\fR
        \fI\(-> This is foo in ::abc\fR
# Direct access via the linked command
puts "Step 3:"; ExternalCall
        \fI\(-> Step 3:\fR
        \fI\(-> This is foo in ::abc\fR
.CE
.PP
This example shows that multiple linked commands can be made in a call to
\fBlink\fR, and that they can handle arguments.

.CS

    constructor {} {
        \fBlink\fR a b c

.SH NAME
lpop \- Get and remove an element in a list
.SH SYNOPSIS
\fBlpop \fIvarName ?index ...?\fR
.BE
.SH DESCRIPTION
.PP
The \fBlpop\fR command accepts a parameter, \fIvarName\fR, which
it interprets as the name of a variable containing a Tcl list.
It also accepts one or more \fIindices\fR into
the list. If no indices are presented, it defaults to "end".
.PP
When presented with a single index, the \fBlpop\fR command
addresses the \fIindex\fR'th element in it, removes if from the list
and returns the element.
.PP
If \fIindex\fR is negative or greater or equal than the number
of elements in \fI$varName\fR, then an error occurs.
.PP
The interpretation of each simple \fIindex\fR value is the same as
for the command \fBstring index\fR, supporting simple index
arithmetic and indices relative to the end of the list.
.PP
If additional \fIindex\fR arguments are supplied, then each argument is
used in turn to address an element within a sublist designated
by the previous indexing operation,
allowing the script to remove elements in sublists.
The command,
.PP
.CS
\fBlpop\fR a 1 2
.CE
.PP
gets and removes element 2 of sublist 1.
.PP
.SH EXAMPLES
.PP
In each of these examples, the initial value of \fIx\fR is:
.PP
.CS
set x [list [list a b c] [list d e f] [list g h i]]
      \fI\(-> {a b c} {d e f} {g h i}\fR
.CE
.PP
The indicated value becomes the new value of \fIx\fR
(except in the last case, which is an error which leaves the value of
\fIx\fR unchanged.)
.PP
.CS
\fBlpop\fR x 0
      \fI\(-> {d e f} {g h i}\fR
\fBlpop\fR x 2
      \fI\(-> {a b c} {d e f}\fR
\fBlpop\fR x end
      \fI\(-> {a b c} {d e f}\fR
\fBlpop\fR x end-1

In the following examples, the initial value of \fIx\fR is:

.SH NAME
lremove \- Remove elements from a list by index
.SH SYNOPSIS
\fBlremove \fIlist\fR ?\fIindex ...\fR?
.BE
.SH DESCRIPTION
.PP
\fBlremove\fR returns a new list formed by simultaneously removing zero or
more elements of \fIlist\fR at each of the indices given by an arbirary number
of \fIindex\fR arguments. The indices may be in any order and may be repeated;
the element at index will only be removed once.  The index values are
interpreted the same as index values for the command \fBstring index\fR,
supporting simple index arithmetic and indices relative to the end of the
list.  0 refers to the first element of the list, and \fBend\fR refers to the
last element of the list.
.SH EXAMPLES
.PP
Removing the third element of a list:
.PP
.CS
% \fBlremove\fR {a b c d e} 2
a b d e

.SH NAME
lreplace \- Replace elements in a list with new elements
.SH SYNOPSIS
\fBlreplace \fIlist first last \fR?\fIelement element ...\fR?
.BE
.SH DESCRIPTION
.PP
\fBlreplace\fR returns a new list formed by replacing one or more elements of
\fBlreplace\fR returns a new list formed by replacing zero or more elements of
\fIlist\fR with the \fIelement\fR arguments.
\fIfirst\fR and \fIlast\fR are index values specifying the first and
last elements of the range to replace.
The index values \fIfirst\fR and \fIlast\fR are interpreted
the same as index values for the command \fBstring index\fR,
supporting simple index arithmetic and indices relative to the
end of the list.
0 refers to the first element of the
list, and \fBend\fR refers to the last element of the list.
If \fIlist\fR is empty, then \fIfirst\fR and \fIlast\fR are ignored.
.PP
If \fIfirst\fR is less than zero, it is considered to refer to before the
first element of the list.  For non-empty lists, the element indicated
by \fIfirst\fR must exist or \fIfirst\fR must indicate before the
start of the list.
If either \fIfirst\fR or \fIlast\fR is less than zero, it is considered
to refer to before the first element of the list. This allows \fBlreplace\fR
to prepend elements to \fIlist\fR.
.VS TIP505
If either \fIfirst\fR or \fIlast\fR indicates a position greater than the
index of the last element of the list, it is treated as if it is an
index one greater than the last element. This allows \fBlreplace\fR to
append elements to \fIlist\fR.
.VE TIP505
.PP
If \fIlast\fR is less than \fIfirst\fR, then any specified elements
will be inserted into the list before the point specified by \fIfirst\fR
will be inserted into the list before the element specified by \fIfirst\fR
with no elements being deleted.
.PP
The \fIelement\fR arguments specify zero or more new arguments to
The \fIelement\fR arguments specify zero or more new elements to
be added to the list in place of those that were deleted.
Each \fIelement\fR argument will become a separate element of
the list.  If no \fIelement\fR arguments are specified, then the elements
between \fIfirst\fR and \fIlast\fR are simply deleted.  If \fIlist\fR
between \fIfirst\fR and \fIlast\fR are simply deleted.
is empty, any \fIelement\fR arguments are added to the end of the list.

to \fBTcl_Alloc\fR causes a line of trace information to be written to
\fIstderr\fR, consisting of the word \fITcl_Alloc\fR, followed by the
address returned, the amount of memory allocated, and the C filename
and line number of the code performing the allocation.  For example:
.RS
.PP

Tcl_Alloc 40e478 98 tclProc.c 1406

\fBmemory trace_on_at_malloc\fR \fIcount\fR
.
Enable memory tracing after \fIcount\fR \fBckalloc\fRs have been performed.
Enable memory tracing after \fIcount\fR \fBTcl_Alloc\fRs have been performed.
For example, if you enter \fBmemory trace_on_at_malloc 100\fR,
after the 100th call to \fBckalloc\fR, memory trace information will begin
after the 100th call to \fBTcl_Alloc\fR, memory trace information will begin
being displayed for all allocations and frees.  Since there can be a lot
of memory activity before a problem occurs, judicious use of this option
can reduce the slowdown caused by tracing (and the amount of trace information
produced), if you can identify a number of allocations that occur before
the problem sets in.  The current number of memory allocations that have
occurred since Tcl started is printed on a guard zone failure.
.TP
\fBmemory validate \fR[\fBon\fR|\fBoff\fR]
.
Turns memory validation on or off. When memory validation is enabled,
on every call to \fBckalloc\fR or \fBckfree\fR, the guard zones are
on every call to \fBTcl_Alloc\fR or \fBTcl_Free\fR, the guard zones are
checked for every piece of memory currently in existence that was
allocated by \fBckalloc\fR.  This has a large performance impact and
allocated by \fBTcl_Alloc\fR.  This has a large performance impact and
should only be used when overwrite problems are strongly suspected.
The advantage of enabling memory validation is that a guard zone
overwrite can be detected on the first call to \fBckalloc\fR or
\fBckfree\fR after the overwrite occurred, rather than when the
overwrite can be detected on the first call to \fBTcl_Alloc\fR or
\fBTcl_Free\fR after the overwrite occurred, rather than when the
specific memory with the overwritten guard zone(s) is freed, which may
occur long after the overwrite occurred.

The object upon which the method is invoked via \fBmy\fR is the one that owns
the namespace that the \fBmy\fR command is contained in initially (\fBNB:\fR the link
remains if the command is renamed), which is the currently invoked object by
default.
.VS TIP478
Similarly, the object on which the method is invoked via \fBmyclass\fR is the
object that is the current class of the object that owns the namespace that
the \fBmyclass\fR command is contained in initially. As with \fBmy\fR, the
link remains even if the command is renamed into another namespace, and
defaults to being the manufacturing class of the current object.

This example shows basic use of \fBmy\fR to use the \fBvariables\fR method of
the \fBoo::object\fR class, which is not publicly visible by default:
.PP
.CS
oo::class create c {
    method count {} {
        \fBmy\fR variable counter
        puts [incr counter]
    }
}

.CE
.PP
This example shows how you can use \fBmy\fR to make callbacks to private
methods from outside the object (from a \fBtrace\fR), using
\fBnamespace code\fR to enter the correct context. (See the \fBcallback\fR
command for the recommended way of doing this.)
.PP

.fi
.BE
.SH DESCRIPTION
.PP
This document describes commands looking up a prefix in a list of strings.
The following commands are supported:
.TP
\fB::tcl::prefix all\fR \fItable\fR \fIstring\fR
\fB::tcl::prefix all\fR \fItable string\fR
.
Returns a list of all elements in \fItable\fR that begin with the prefix
\fIstring\fR.
.TP
\fB::tcl::prefix longest\fR \fItable\fR \fIstring\fR
\fB::tcl::prefix longest\fR \fItable string\fR
.
Returns the longest common prefix of all elements in \fItable\fR that
begin with the prefix \fIstring\fR.
.TP
\fB::tcl::prefix match\fR ?\fIoptions\fR? \fItable\fR \fIstring\fR
\fB::tcl::prefix match\fR ?\fIoptions\fR? \fItable string\fR
.
If \fIstring\fR equals one element in \fItable\fR or is a prefix to exactly
one element, the matched element is returned. If not, the result depends
on the \fB\-error\fR option. (It is recommended that the \fItable\fR be sorted
before use with this subcommand, so that the list of matches presented in the
error message also becomes sorted, though this is not strictly necessary for
the operation of this subcommand itself.)

.SH NAME
tcl::process \- Subprocess management
.SH SYNOPSIS
\fB::tcl::process \fIoption \fR?\fIarg arg ...\fR?
.BE
.SH DESCRIPTION
.PP
This command provides a way to manage subprocesses created by the \fBopen\fR
and \fBexec\fR commands, as identified by the process identifiers (PIDs) of
those subprocesses. The legal \fIoptions\fR (which may be abbreviated) are:
.TP
\fB::tcl::process autopurge\fR ?\fIflag\fR?
.
Automatic purge facility. If \fIflag\fR is specified as a boolean value then
it activates or deactivate autopurge. In all cases it returns the current
status as a boolean value. When autopurge is active,
\fBTcl_ReapDetachedProcs\fR is called each time the \fBexec\fR command is
executed or a pipe channel created by \fBopen\fR is closed. When autopurge is
inactive, \fB::tcl::process\fR purge must be called explicitly. By default
autopurge is active.
.TP
\fB::tcl::process list\fR
.
Returns the list of subprocess PIDs. This includes all currently executing
subprocesses and all terminated subprocesses that have not yet had their
corresponding process table entries purged.
.TP
\fB::tcl::process purge\fR ?\fIpids\fR?
.
Cleans up all data associated with terminated subprocesses. If \fIpids\fR is
specified as a list of PIDs then the command only cleanup data for the matching
subprocesses if they exist, and raises an error otherwise. If a process listed is
still active, this command does nothing to that process.
.TP
\fB::tcl::process status\fR ?\fIswitches\fR? ?\fIpids\fR?
.
Returns a dictionary mapping subprocess PIDs to their respective status. If
\fIpids\fR is specified as a list of PIDs then the command only returns the
status of the matching subprocesses if they exist, and raises an error
otherwise. For active processes, the status is an empty value. For terminated
processes, the status is a list with the following format:
.QW "\fB{\fIcode\fR ?\fImsg errorCode\fR?\fB}\fR" ,
where:
.RS
.TP
\fIcode\fR\0
.
is a standard Tcl return code, i.e., \fB0\fR for TCL_OK and \fB1\fR
for TCL_ERROR,
.TP
\fImsg\fR\0
.
is the human-readable error message,
.TP
\fIerrorCode\fR\0
.
uses the same format as the \fBerrorCode\fR global variable
.PP
Note that \fBmsg\fR and \fBerrorCode\fR are only present for abnormally
terminated processes (i.e. those where the \fIcode\fR is nonzero). Under the
hood this command calls \fBTcl_WaitPid\fR with the \fBWNOHANG\fR flag set for
non-blocking behavior, unless the \fB\-wait\fR switch is set (see below).
.PP
Additionally, \fB::tcl::process status\fR accepts the following switches:
.TP
\fB\-wait\fR\0
.
By default the command returns immediately (the underlying \fBTcl_WaitPid\fR is
called with the \fBWNOHANG\fR flag set) unless this switch is set. If \fIpids\fR
is specified as a list of PIDs then the command waits until the status of the
matching subprocesses are available. If \fIpids\fR was not specified, this
command will wait for all known subprocesses.
.TP
\fB\-\|\-\fR
.
Marks the end of switches.  The argument following this one will
be treated as the first \fIarg\fR even if it starts with a \fB\-\fR.

.SH NAME
oo::singleton \- a class that does only allows one instance of itself
.SH SYNOPSIS
.nf
package require TclOO

\fBoo::singleton\fI method \fR?\fIarg ...\fR?
.fi
.SH "CLASS HIERARCHY"
.nf
\fBoo::object\fR
   \(-> \fBoo::class\fR
       \(-> \fBoo::singleton\fR
.fi
.BE
.SH DESCRIPTION
Singleton classes are classes that only permit at most one instance of
themselves to exist. They unexport the \fBcreate\fR and
\fBcreateWithNamespace\fR methods entirely, and override the \fBnew\fR method
so that it only makes a new instance if there is no existing instance.  It is
not recommended to inherit from a singleton class; singleton-ness is \fInot\fR
inherited. It is not recommended that a singleton class's constructor take any
arguments.
.PP
Instances have their\fB destroy\fR method overridden with a method that always
returns an error in order to discourage destruction of the object, but
destruction remains possible if strictly necessary (e.g., by destroying the
class or using \fBrename\fR to delete it). They also have a (non-exported)
\fB<cloned>\fR method defined on them that similarly always returns errors to
make attempts to use the singleton instance with \fBoo::copy\fR fail.
.SS CONSTRUCTOR
The \fBoo::singleton\fR class does not define an explicit constructor; this
means that it is effectively the same as the constructor of the
\fBoo::class\fR class.
.SS DESTRUCTOR
The \fBoo::singleton\fR class does not define an explicit destructor;
destroying an instance of it is just like destroying an ordinary class (and
will destroy the singleton object).

\fIcls \fBnew \fR?\fIarg ...\fR?
.
This returns the current instance of the singleton class, if one exists, and
creates a new instance only if there is no existing instance. The additional
arguments, \fIarg ...\fR, are only used if a new instance is actually
manufactured; that construction is via the \fBoo::class\fR class's \fBnew\fR
method.
.RS
.PP
This is an override of the behaviour of a superclass's method with an
identical call signature to the superclass's implementation.
.RE
.SS "NON-EXPORTED METHODS"
The \fBoo::singleton\fR class explicitly states that \fBcreate\fR and
\fBcreateWithNamespace\fR are unexported; callers should not assume that they
have control over either the name or the namespace name of the singleton instance.
.SH EXAMPLE
.PP
This example demonstrates that there is only one instance even though the
\fBnew\fR method is called three times.
.PP
.CS
\fBoo::singleton\fR create Highlander {
    method say {} {
        puts "there can be only one"

.SH SYNOPSIS
\fBstring \fIoption arg \fR?\fIarg ...?\fR
\fBstring \fIoption arg \fR?\fIarg ...\fR?
.BE
.SH DESCRIPTION
.PP
Performs one of several string operations, depending on \fIoption\fR.
The legal \fIoption\fRs (which may be abbreviated) are:
.TP
\fBstring cat\fR ?\fIstring1\fR? ?\fIstring2...\fR?
.VS 8.6.2
.
Concatenate the given \fIstring\fRs just like placing them directly
next to each other and return the resulting compound string.  If no
\fIstring\fRs are present, the result is an empty string.
.RS
.PP
This primitive is occasionally handier than juxtaposition of strings
when mixed quoting is wanted, or when the aim is to return the result
of a concatenation without resorting to \fBreturn\fR \fB\-level 0\fR,
and is more efficient than building a list of arguments and using
\fBjoin\fR with an empty join string.
.RE

.TP
\fBstring compare\fR ?\fB\-nocase\fR? ?\fB\-length\fI length\fR? \fIstring1 string2\fR
.
Perform a character-by-character comparison of strings \fIstring1\fR
and \fIstring2\fR.  Returns \-1, 0, or 1, depending on whether
\fIstring1\fR is lexicographically less than, equal to, or greater
than \fIstring2\fR.  If \fB\-length\fR is specified, then only the

\fBstring insert \fIstring index insertString\fR

Returns a copy of \fIstring\fR with \fIinsertString\fR inserted at the
\fIindex\fR'th character.  The \fIindex\fR may be specified as described in the
\fBSTRING INDICES\fR section.
.RS
.PP
If \fIindex\fR is start-relative, the first character inserted in the returned
string will be at the specified index.  If \fIindex\fR is end-relative, the last
character inserted in the returned string will be at the specified index.
.PP
If \fIindex\fR is at or before the start of \fIstring\fR (e.g., \fIindex\fR is
\fB0\fR), \fIinsertString\fR is prepended to \fIstring\fR.  If \fIindex\fR is at
or after the end of \fIstring\fR (e.g., \fIindex\fR is \fBend\fR),
\fIinsertString\fR is appended to \fIstring\fR.

Returns a range of consecutive characters from \fIstring\fR, starting
with the character whose index is \fIfirst\fR and ending with the
character whose index is \fIlast\fR. An index of 0 refers to the first
character whose index is \fIlast\fR (using the forms described in
\fBSTRING INDICES\fR). An index of \fB0\fR refers to the first
character of the string; an index of \fBend\fR refers to last
character of the string.  \fIfirst\fR and \fIlast\fR may be specified
as for the \fBindex\fR method.  If \fIfirst\fR is less than zero then
it is treated as if it were zero, and if \fIlast\fR is greater than or
equal to the length of the string then it is treated as if it were

When a zipfile is concatenated to the end of a \fBtclsh\fR, on
startup the contents of the zip archive will be mounted as the

present in the zip archive, it will become the directory loaded
as env(TCL_LIBRARY). If a file named \fBmain.tcl\fR is present
in the top level directory of the zip archive, it will be sourced
instead of the shell's normal command line handing.

.SH NAME
timerate \- Calibrated performance measurements of script execution time
.SH SYNOPSIS
\fBtimerate \fIscript\fR ?\fItime\fR? ?\fImax-count\fR?
.sp
\fBtimerate \fR?\fB\-direct\fR? ?\fB\-overhead\fI double\fR? \fIscript\fR ?\fItime\fR? ?\fImax-count\fR?
.sp
\fBtimerate \fR?\fB\-calibrate\fR? ?\fB\-direct\fR? \fIscript\fR ?\fItime\fR? ?\fImax-count\fR?
.BE
.SH DESCRIPTION
.PP
The \fBtimerate\fR command does calibrated performance measurement of a Tcl
command or script, \fIscript\fR. The \fIscript\fR should be written so that it
can be executed multiple times during the performance measurement process.
Time is measured in elapsed time using the finest timer resolution as possible,
not CPU time; if \fIscript\fR interacts with the OS, the cost of that
interaction is included.
This command may be used to provide information as to how well a script or
Tcl command is performing, and can help determine bottlenecks and fine-tune
application performance.
.PP
The first and second form will evaluate \fIscript\fR until the interval
\fItime\fR given in milliseconds elapses, or for 1000 milliseconds (1 second)
if \fItime\fR is not specified.
.sp
The parameter \fImax-count\fR could additionally impose a further restriction
by the maximal number of iterations to evaluate the script.
If \fImax-count\fR is specified, the evalution will stop either this count of
iterations is reached or the time is exceeded.
.sp
It will then return a canonical tcl-list of the form:
.PP
.CS
\fB0.095977 \(mcs/# 52095836 # 10419167 #/sec 5000.000 net-ms\fR
.CE
.PP
which indicates:
.IP \(bu 3
the average amount of time required per iteration, in microseconds ([\fBlindex\fR $result 0])
.IP \(bu 3
the count how many times it was executed ([\fBlindex\fR $result 2])
.IP \(bu 3
the estimated rate per second ([\fBlindex\fR $result 4])
.IP \(bu 3
the estimated real execution time without measurement overhead ([\fBlindex\fR $result 6])
.PP
The following options may be supplied to the \fBtimerate\fR command:
.TP
\fB\-calibrate\fR
.
To measure very fast scripts as exactly as possible, a calibration process
may be required.
The \fB\-calibrate\fR option is used to calibrate \fBtimerate\fR itself,
calculating the estimated overhead of the given script as the default overhead
for future invocations of the \fBtimerate\fR command. If the \fItime\fR
parameter is not specified, the calibrate procedure runs for up to 10 seconds.
.RS
.PP
Note that calibration is not thread safe in the current implementation.
.RE
.TP
\fB\-overhead \fIdouble\fR
.
The \fB\-overhead\fR parameter supplies an estimate (in microseconds) of the
measurement overhead of each iteration of the tested script. This quantity
will be subtracted from the measured time prior to reporting results. This can
be useful for removing the cost of interpreter state reset commands from the
script being measured.
.TP
\fB\-direct\fR
.
The \fB-direct\fR option causes direct execution of the supplied script,
without compilation, in a manner similar to the \fBtime\fR command. It can be
used to measure the cost of \fBTcl_EvalObjEx\fR, of the invocation of canonical
lists, and of the uncompiled versions of bytecoded commands.
.PP
As opposed to the \fBtime\fR commmand, which runs the tested script for a fixed
number of iterations, the timerate command runs it for a fixed time.
Additionally, the compiled variant of the script will be used during the entire
measurement, as if the script were part of a compiled procedure, if the \fB\-direct\fR
option is not specified. The fixed time period and possibility of compilation allow
for more precise results and prevent very long execution times by slow scripts, making
it practical for measuring scripts with highly uncertain execution times.
.SH EXAMPLES
Estimate how fast it takes for a simple Tcl \fBfor\fR loop (including
operations on variable \fIi\fR) to count to ten:
.PP
.CS
\fI# calibrate\fR
\fBtimerate\fR -calibrate {}

\fI# measure\fR
\fBtimerate\fR { for {set i 0} {$i<10} {incr i} {} } 5000
.CE
.PP
Estimate how fast it takes for a simple Tcl \fBfor\fR loop, ignoring the
overhead of the management of the variable that controls the loop:
.PP
.CS
\fI# calibrate for overhead of variable operations\fR
set i 0; \fBtimerate\fR -calibrate {expr {$i<10}; incr i} 1000

\fI# measure\fR
\fBtimerate\fR {
    for {set i 0} {$i<10} {incr i} {}
} 5000
.CE
.PP
Estimate the speed of calculating the hour of the day using \fBclock format\fR only,
ignoring overhead of the portion of the script that prepares the time for it to
calculate:
.PP
.CS
\fI# calibrate\fR
\fBtimerate\fR -calibrate {}

\fI# estimate overhead\fR
set tm 0
set ovh [lindex [\fBtimerate\fR {
    incr tm [expr {24*60*60}]
}] 0]

\fI# measure using estimated overhead\fR
set tm 0
\fBtimerate\fR -overhead $ovh {
    clock format $tm -format %H
    incr tm [expr {24*60*60}]; # overhead for this is ignored

been passed to \fBconcat\fR; the result is then evaluated in the
variable context indicated by \fIlevel\fR.  \fBUplevel\fR returns
the result of that evaluation.
.PP
If \fIlevel\fR is an integer then
it gives a distance (up the procedure calling stack) to move before
executing the command.  If \fIlevel\fR consists of \fB#\fR followed by
a number then the number gives an absolute level number.  If \fIlevel\fR
a integer then the level gives an absolute level.  If \fIlevel\fR
is omitted then it defaults to \fB1\fR.  \fILevel\fR cannot be
defaulted if the first \fIcommand\fR argument starts with a digit or \fB#\fR.
defaulted if the first \fIcommand\fR argument is an integer or starts with \fB#\fR.
.PP
For example, suppose that procedure \fBa\fR was invoked
from top-level, and that it called \fBb\fR, and that \fBb\fR called \fBc\fR.
Suppose that \fBc\fR invokes the \fBuplevel\fR command.  If \fIlevel\fR
is \fB1\fR or \fB#2\fR  or omitted, then the command will be executed
in the variable context of \fBb\fR.  If \fIlevel\fR is \fB2\fR or \fB#1\fR
then the command will be executed in the variable context of \fBa\fR.

modified to hold the result or error message from the script.
.AP "const char" *zipname in
Name of a ZIP file. Must not be NULL when either mounting or unmounting a ZIP.
.AP "const char" *mountpoint in
Name of a mount point, which must be a legal Tcl file or directory name. May
be NULL to query current mount points.
.AP "const char" *password in
An (optional) password. Use NULL if no password is wanted to read the file.
.AP "unsigned char" *data in
A data buffer to mount. The data buffer must hold the contents of a ZIP
archive, and must not be NULL.
.AP size_t dataLen in
The number of bytes in the supplied data buffer argument, \fIdata\fR.
.AP int copy in
If non-zero, the ZIP archive in the data buffer will be internally copied
before mounting, allowing the data buffer to be disposed once
\fBTclZipfs_MountBuffer\fR returns. If zero, the caller guarantees that the
buffer will be valid to read from for the duration of the mount.
.BE
.SH DESCRIPTION
\fBTclZipfs_AppHook\fR is a utility function to perform standard application
initialization procedures, taking into account available ZIP archives as
follows:
.IP [1]
If the current application has a mountable ZIP archive, that archive is
mounted under \fIZIPFS_VOLUME\fB/app\fR as a read-only Tcl virtual file
system. \fIZIPFS_VOLUME\fR is usually \fB//zipfs:\fR on all platforms, but
\fBzipfs:\fR may also be used on Windows (due to differences in the
platform's filename parsing).
.IP [2]
If a file named \fBmain.tcl\fR is located in the root directory of that file
system (i.e., at \fIZIPROOT\fB/app/main.tcl\fR after the ZIP archive is
mounted as described above) it is treated as the startup script for the
process.
.IP [3]
If the file \fIZIPROOT\fB/app/tcl_library/init.tcl\fR is present, the
\fBtcl_library\fR global variable in the initial Tcl interpreter is set to
\fIZIPROOT\fB/app/tcl_library\fR.
.IP [4]
If the directory \fBtcl_library\fR was not found in the main application
mount, the system will then search for it as either a VFS attached to the
application dynamic library, or as a zip archive named
\fBlibtcl_\fImajor\fB_\fIminor\fB_\fIpatchlevel\fB.zip\fR either in the
present working directory or in the standard Tcl install location. (For
example, the Tcl 8.7.2 release would be searched for in a file
\fBlibtcl_8_7_2.zip\fR.) That archive, if located, is also mounted read-only.
.PP
On Windows, \fBTclZipfs_AppHook\fR has a slightly different signature, since
it uses WCHAR in stead of char. As a result, it requires your application to
be compiled with the UNICODE preprocessor symbol defined (e.g., via the
\fB-DUNICODE\fR compiler flag).
.PP
The result of \fBTclZipfs_AppHook\fR is a Tcl result code (e.g., \fBTCL_OK\fR
when the function is successful). The function \fImay\fR modify the variables
pointed to by \fIargcPtr\fR and \fIargvPtr\fR to remove arguments; the
current implementation does not do so, but callers \fIshould not\fR assume
that this will be true in the future.
.PP
\fBTclzipfs_Mount\fR mounts the ZIP archive \fIzipname\fR on the mount point
given in \fImountpoint\fR using the optional ZIP password \fIpassword\fR.
Errors during that process are reported in the interpreter \fIinterp\fR.  If
\fImountpoint\fR is a NULL pointer, information on all currently mounted ZIP
file systems is written into \fIinterp\fR's result as a sequence of mount
points and ZIP file names.  The result of this call is a standard Tcl result
code.
.PP
\fBTclzipfs_MountBuffer\fR mounts the ZIP archive in the buffer pointed to by
\fIdata\fR on the mount point given in \fImountpoint\fR. The ZIP archive is
assumed to be not password protected.  Errors during that process are reported
in the interpreter \fIinterp\fR. The \fIcopy\fR argument determines whether
the buffer is internally copied before mounting or not. The result of this
call is a standard Tcl result code.
.PP
\fBTclzipfs_Unmount\fR undoes the effect of \fBTclzipfs_Mount\fR, i.e., it
unmounts the mounted ZIP file system that was mounted from \fIzipname\fR (at
\fImountpoint\fR). Errors are reported in the interpreter \fIinterp\fR.  The
result of this call is a standard Tcl result code.
.PP
\fBTclZipfs_AppHook\fR can not be used in stub-enabled extensions.

.BE
.SH DESCRIPTION
.PP
The \fBzipfs\fR command (the sole public command provided by the built-in
package with the same name) provides Tcl with the ability to mount the
contents of a ZIP archive file as a virtual file system. ZIP archives support
simple encryption, sufficient to prevent casual inspection of their contents
but not able to prevent access by even a moderately determined attacker.
.TP
\fBzipfs canonical\fR ?\fImountpoint\fR? \fIfilename\fR ?\fIinZipfs\fR?
.
This takes the name of a file, \fIfilename\fR, and produces where it would be
mapped into a zipfs mount as its result. If specified, \fImountpoint\fR says
within which mount the mapping will be done; if omitted, the main root of the
zipfs system is used. The \fIinZipfs\fR argument is a an optional boolean
which controls whether to fully canonicalise the name; it defaults to true.
.TP
\fBzipfs exists\fR \fIfilename\fR
.
Return 1 if the given filename exists in the mounted zipfs and 0 if it does not.
.TP
\fBzipfs find\fR \fIdirectoryName\fR
.
Recursively lists files including and below the directory \fIdirectoryName\fR.
The result list consists of relative path names starting from the given
directory. This command is also used by the \fBzipfs mkzip\fR and \fBzipfs
mkimg\fR commands.
.TP
\fBzipfs info\fR \fIfile\fR
.
Return information about the given \fIfile\fR in the mounted zipfs.  The
information consists of:
.RS
.IP (1)
the name of the ZIP archive file that contains the file,
.IP (2)
the size of the file after decompressions,
.IP (3)
the compressed size of the file, and
.IP (4)
the offset of the compressed data in the ZIP archive file.
.PP
Note: querying the mount point gives the start of the zip data as the offset
in (4), which can be used to truncate the zip information from an executable.
.RE
.TP
\fBzipfs list\fR ?(\fB\-glob\fR|\fB\-regexp\fR)? ?\fIpattern\fR?
.
Return a list of all files in the mounted zipfs, or just those matching
\fIpattern\fR (optionally controlled by the option parameters).  The order of
the names in the list is arbitrary.
.TP
\fBzipfs mount ?\fImountpoint\fR? ?\fIzipfile\fR? ?\fIpassword\fR?
.
The \fBzipfs mount\fR command mounts a ZIP archive file as a Tcl virtual
filesystem at \fImountpoint\fR.  After this command executes, files contained
in \fIzipfile\fR will appear to Tcl to be regular files at the mount point.
.RS
.PP
With no \fIzipfile\fR, returns the zipfile mounted at \fImountpoint\fR.  With
no \fImountpoint\fR, return all zipfile/mount pairs.  If \fImountpoint\fR is
specified as an empty string, mount on file path.
.PP
\fBNB:\fR because the current working directory is a concept maintained by the
operating system, using \fBcd\fR into a mounted archive will only work in the
current process, and then not entirely consistently (e.g., if a shared library
uses direct access to the OS rather than through Tcl's filesystem API, it will
not see the current directory as being inside the mount and will not be able
to access the files inside the mount).
.RE
.TP
\fBzipfs root\fR
.
Returns a constant string which indicates the mount point for zipfs volumes
for the current platform. On Windows, this value is
.QW \fBzipfs:/\fR .
On Unix, this value is
.QW \fB//zipfs:/\fR .
.TP
\fBzipfs unmount \fImountpoint\fR
.
Unmounts a previously mounted ZIP archive mounted to \fImountpoint\fR.
.SS "ZIP CREATION COMMANDS"
This package also provides several commands to aid the creation of ZIP
archives as Tcl applications.
.TP
\fBzipfs mkzip\fR \fIoutfile indir\fR ?\fIstrip\fR? ?\fIpassword\fR?
.
Creates a ZIP archive file named \fIoutfile\fR from the contents of the input
directory \fIindir\fR (contained regular files only) with optional ZIP
password \fIpassword\fR. While processing the files below \fIindir\fR the
optional file name prefix given in \fIstrip\fR is stripped off the beginning
of the respective file name.  When stripping, it is common to remove either
the whole source directory name or the name of its parent directory.
.RS
.PP
\fBCaution:\fR the choice of the \fIindir\fR parameter (less the optional
stripped prefix) determines the later root name of the archive's content.
.RE
.TP
\fBzipfs mkimg\fR \fIoutfile indir\fR ?\fIstrip\fR? ?\fIpassword\fR? ?\fIinfile\fR?
.
Creates an image (potentially a new executable file) similar to \fBzipfs
mkzip\fR; see that command for a description of most parameters to this
command, as they behave identically here.
.RS
.PP
If the \fIinfile\fR parameter is specified, this file is prepended in front of
the ZIP archive, otherwise the file returned by \fBinfo nameofexecutable\fR
(i.e., the executable file of the running process) is used. If the
\fIpassword\fR parameter is not empty, an obfuscated version of that password
(see \fBzipfs mkkey\fR) is placed between the image and ZIP chunks of the
output file and the contents of the ZIP chunk are protected with that
password.
.PP
If there is a file, \fBmain.tcl\fR, in the root directory of the resulting
archive and the image file that the archive is attached to is a \fBtclsh\fR
(or \fBwish\fR) instance (true by default, but depends on your configuration),
then the resulting image is an executable that will \fBsource\fR the script in
that \fBmain.tcl\fR after mounting the ZIP archive, and will \fBexit\fR once
that script has been executed.
.PP
\fBCaution:\fR highly experimental, not usable on Android, only partially
tested on Linux and Windows.
.RE
.TP
\fBzipfs mkkey\fR \fIpassword\fR
.
Given the clear text \fIpassword\fR argument, an obfuscated string version is
returned with the same format used in the \fBzipfs mkimg\fR command.
.TP
\fBzipfs lmkimg\fR \fIoutfile inlist\fR ?\fIpassword infile\fR?
.
This command is like \fBzipfs mkimg\fR, but instead of an input directory,
\fIinlist\fR must be a Tcl list where the odd elements are the names of files
to be copied into the archive in the image, and the even elements are their
respective names within that archive.
.TP
\fBzipfs lmkzip\fR \fIoutfile inlist\fR ?\fIpassword\fR?
.
This command is like \fBzipfs mkzip\fR, but instead of an input directory,
\fIinlist\fR must be a Tcl list where the odd elements are the names of files
to be copied into the archive, and the even elements are their respective
names within that archive.
.SH "EXAMPLES"
.PP
Mounting an ZIP archive as an application directory and running code out of it
before unmounting it again:
.PP
.CS
set zip myApp.zip
set base [file join [\fBzipfs root\fR] myApp]

\fBzipfs mount\fR $base $zip
# $base now has the contents of myApp.zip

source [file join $base app.tcl]
# use the contents, load libraries from it, etc...

\fBzipfs unmount\fR $zip
.CE
.PP
Creating a ZIP archive, given that a directory exists containing the content
to put in the archive. Note that the source directory is given twice, in order
to strip the exterior directory name from each filename in the archive.
.PP
.CS
set sourceDirectory [file normalize myApp]
set targetZip myApp.zip

\fBzipfs mkzip\fR $targetZip $sourceDirectory $sourceDirectory
.CE
.PP
Encryption can be applied to ZIP archives by providing a password when
building the ZIP and when mounting it.
.PP
.CS
set zip myApp.zip
set sourceDir [file normalize myApp]
set password "hunter2"
set base [file join [\fBzipfs root\fR] myApp]

# Create with password
\fBzipfs mkzip\fR $targetZip $sourceDir $sourceDir $password

# Mount with password
\fBzipfs mount\fR $base $zip $password
.CE
.PP
When creating an executable image with a password, the password is placed
within the executable in a shrouded form so that the application can read
files inside the embedded ZIP archive yet casual inspection cannot read it.
.PP
.CS
set appDir [file normalize myApp]
set img "myApp.bin"
set password "hunter2"

# Create some simple content to define a basic application
file mkdir $appDir
set f [open $appDir/main.tcl]
puts $f {
    puts "Hi. This is [info script]"
}
close $f

# Create the executable
\fBzipfs mkimg\fR $img $appDir $appDir $password

# Launch the executable, printing its output to stdout
exec $img >@stdout
#    prints: \fIHi. This is //zipfs:/app/main.tcl\fR

 * A bytearray is an ordered sequence of bytes. Each byte is an integer

 * encode each value in the value set as a Tcl string.  The simplest
 * encoding is to represent each byte value as the same codepoint value.
 * A bytearray of N bytes is encoded into a Tcl string of N characters
 * where the codepoint of each character is the value of corresponding byte.
 * This approach creates a one-to-one map between all bytearray values

       the only way this function was invoked is if the default action
       is an error action.  In that case, don't check for expected
       tokens because there are none.
     - The only way there can be no lookahead present (in yychar) is if
       this state is a consistent state with a default action.  Thus,
       detecting the absence of a lookahead is sufficient to determine
       that there is no unexpected or expected token to report.  In that
       case, just report a simple "syntax error".
     - Don't assume there isn't a lookahead just because this state is a
       consistent state with a default action.  There might have been a
       previous inconsistent state, consistent state with a non-default
       action, or user semantic action that manipulated yychar.
     - Of course, the expected token list depends on states to have
       correct lookahead information, and it depends on the parser not
       to perform extra reductions after fetching a lookahead from the
       scanner and before detecting a syntax error.  Thus, state merging
       (from LALR or IELR) and default reductions corrupt the expected
       token list.  However, the list is correct for canonical LR with
       one exception: it will still contain any token that will not be
       accepted due to an error action in a later state.

 *	and target interpreters of the alias are the same. That lets a number
 *	of safety precautions be avoided: the state is much more precisely
 *	known.

 * Results:
 *	A standard Tcl result.
 *
 * Side effects:
 *	Causes forwarding of the invocation; all possible side effects may
 *	occur as a result of invoking the command to which the invocation is

/*
 * The following table provides parsing information about each possible 8-bit
 * character. The table is designed to be referenced with either signed or
 * character. The table is designed to be referenced with unsigned characters.
 * unsigned characters, so it has 384 entries. The first 128 entries
 * correspond to negative character values, the next 256 correspond to
 * positive character values. The last 128 entries are identical to the first
 * 128. The table is always indexed with a 128-byte offset (the 128th entry
 * corresponds to a character value of 0).
 *
 * The macro CHAR_TYPE is used to index into the table and return information
 * about its character argument. The following return values are defined.
 *
 * TYPE_NORMAL -	All characters that don't have special significance to
 *			the Tcl parser.
 * TYPE_SPACE -		The character is a whitespace character other than
 *			newline.
 * TYPE_COMMAND_END -	Character is newline or semicolon.
 * TYPE_SUBS -		Character begins a substitution or has other special
 *			meaning in ParseTokens: backslash, dollar sign, or
 *			open bracket.
 * TYPE_QUOTE -		Character is a double quote.
 * TYPE_CLOSE_PAREN -	Character is a right parenthesis.
 * TYPE_CLOSE_BRACK -	Character is a right square bracket.
 * TYPE_BRACE -		Character is a curly brace (either left or right).

 * Tcl_FSNewNativePath --
 *
 *	This function performs the something like the reverse of the usual
 *	obj->path->nativerep conversions. If some code retrieves a path in
 *	native form (from, e.g. readlink or a native dialog), and that path is
 *	to be used at the Tcl level, then calling this function is an
 *	efficient way of creating the appropriate path object type.
 *
 *	Any memory which is allocated for 'clientData' should be retained
 *	until clientData is passed to the filesystem's freeInternalRepProc
 *	when it can be freed. The built in platform-specific filesystems use
 *	'ckalloc' to allocate clientData, and ckfree to free it.
 *	'Tcl_Alloc' to allocate clientData, and Tcl_Free to free it.
 *
 * Results:
 *	NULL or a valid path object pointer, with refCount zero.
 *
 * Side effects:
 *	New memory may be allocated.

	 * Second, how does this work? If we reach this point, then the global
	 * variable tclEmptyStringRep has the value NULL. Compare that with
	 * the definition of tclEmptyStringRep near the top of this file.
	 * It clearly should not have the value NULL; it
	 * should point to the char tclEmptyString. If we see it having the
	 * value NULL, then somehow we are seeing a Tcl library that isn't
	 * completely initialized, and that's an indicator for the error
	 * condition described above. (Further explanation is welcome.)

 * according to the 'flags' argument. Valid values for 'flags' include:
 *	TCL_DD_SHORTEST - This is the default for floating point conversion.
 *		It constructs the shortest string of
 *		digits that will reconvert to the given number when scanned.
 *		For floating point numbers that are exactly between two
 *		decimal numbers, it resolves using the 'round to even' rule.
 *		With this value, the 'ndigits' parameter is ignored.
 *	TCL_DD_STEELE - This value is not recommended and may be removed in
 *		the future. It follows the conversion algorithm outlined in
 *		"How to Print Floating-Point Numbers Accurately" by Guy
 *		L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90,
 *		pp. 112-126]. This rule has the effect of rendering 1e23 as
 *		9.9999999999999999e22 - which is a 'better' approximation in
 *		the sense that it will reconvert correctly even if a
 *		subsequent input conversion is 'round up' or 'round down'
 *		rather than 'round to nearest', but is surprising otherwise.
 *	TCL_DD_E_FORMAT - This value is used to prepare numbers for %e format
 *		conversion. It constructs a string of at most 'ndigits' digits,
 *		choosing the one that is closest to the given number (and
 *		resolving ties with 'round to even').  It is allowed to return
 *		fewer than 'ndigits' if the number converts exactly; if the
 *		TCL_DD_E_FORMAT|TCL_DD_SHORTEN_FLAG is supplied instead, it
 *		also returns fewer digits if the shorter string will still

 * Tcl_UtfToUniChar --
 *
 *	Extract the Tcl_UniChar represented by the UTF-8 string. Bad UTF-8
 *	sequences are converted to valid Tcl_UniChars and processing
 *	continues. Equivalent to Plan 9 chartorune().
 *
 *	The caller must ensure that the source buffer is long enough that this
 *	routine does not run off the end and dereference non-existent memory
 *	looking for trail bytes. If the source buffer is known to be '\0'
 *	terminated, this cannot happen. Otherwise, the caller should call
 *	Tcl_UtfCharComplete() before calling this routine to ensure that
 *	enough bytes remain in the string.
 *
 *	If TCL_UTF_MAX == 4, special handling of Surrogate pairs is done:
 *	Special handling of Surrogate pairs is handled as follows:
 *	For any UTF-8 string containing a character outside of the BMP, the
 *	first call to this function will fill *chPtr with the high surrogate
 *	and generate a return value of 0. Calling Tcl_UtfToUniChar again
 *	will produce the low surrogate and a return value of 4. Because *chPtr
 *	and generate a return value of 1. Calling Tcl_UtfToUniChar again
 *	will produce the low surrogate and a return value of 3. Because *chPtr
 *	is used to remember whether the high surrogate is already produced, it
 *	is recommended to initialize the variable it points to as 0 before
 *	the first call to Tcl_UtfToUniChar is done.
 *
 * Results:
 *	*chPtr is filled with the Tcl_UniChar, and the return value is the
 *	number of bytes from the UTF-8 string that were consumed.
 *
 * Side effects:
 *	None.

 *
 * TclIndexEncode --
 *
 *      Parse objPtr to determine if it is an index value. Two cases
 *	are possible.  The value objPtr might be parsed as an absolute
 *	index value in the C signed int range.  Note that this includes
 *	index values that are integers as presented and it includes index
 *      arithmetic expressions. The absolute index values that can be
 *	directly meaningful as an index into either a list or a string are
 *	those integer values >= TCL_INDEX_START (0)
 *	and < TCL_INDEX_AFTER (INT_MAX).
 *	and < INT_MAX.
 *      The largest string supported in Tcl 8 has bytelength INT_MAX.
 *      This means the largest supported character length is also INT_MAX,
 *      and the index of the last character in a string of length INT_MAX
 *      is INT_MAX-1.
 *
 *      Any absolute index value parsed outside that range is encoded
 *      using the before and after values passed in by the
 *      caller as the encoding to use for indices that are either
 *      less than or greater than the usable index range. TCL_INDEX_AFTER
 *      less than or greater than the usable index range. TCL_INDEX_NONE
 *      is available as a good choice for most callers to use for
 *      after. Likewise, the value TCL_INDEX_BEFORE is good for
 *      after. Likewise, the value TCL_INDEX_NONE is good for
 *      most callers to use for before.  Other values are possible
 *      when the caller knows it is helpful in producing its own behavior
 *      for indices before and after the indexed item.
 *
 *      A token can also be parsed as an end-relative index expression.
 *      All end-relative expressions that indicate an index larger
 *      than end (end+2, end--5) point beyond the end of the indexed

 * TclArraySet --
 * ArrayForObjCmd, ArrayForNRCmd, ArrayForLoopCallback, ArrayObjNext --
 *
 *	Set the elements of an array. If there are no elements to set, create
 *	an empty array. This routine is used by the Tcl_ArrayObjCmd and by the
 *	TclSetupEnv routine.
 *	These functions implement the "array for" Tcl command.
 *	    array for {k v} a {}
 *	The array for command iterates over the array, setting the the
 *	specified loop variables, and executing the body each iteration.
 *
 * Results:
 *	A standard Tcl result object.
 *	ArrayForObjCmd() is the standard wrapper around ArrayForNRCmd().
 *
 *	ArrayForNRCmd() sets up the ArraySearch structure, sets arrayNamePtr
 * Side effects:
 *	A variable will be created if one does not already exist.
 *	inside the structure and calls VarHashFirstEntry to start the hash
 *	iteration.
 *
 *	ArrayForNRCmd() does not execute the body or set the loop variables,
 *	Callers must Incr arrayNameObj if they pland to Decr it.
 *	it only initializes the iterator.
 *
 *	ArrayForLoopCallback() iterates over the entire array, executing the
 *	body each time.

# libtommath

This is the git repository for [LibTomMath](http://www.libtom.net/LibTomMath/), a free open source portable number theoretic multiple-precision integer (MPI) library written entirely in C.

## Build Status

API/ABI changes: [check here](https://abi-laboratory.pro/tracker/timeline/libtommath/)

## Summary

The `develop` branch contains the in-development version. Stable releases are tagged.

Documentation is built from the LaTeX file `bn.tex`. There is also limited documentation in `tommath.h`. There is also a document, `tommath.pdf`, which describes the goals of the project and many of the algorithms used.

      odd positive integer d and positive integer s for which
      N + 1 = 2^s*d (similar to the step for N - 1 in Miller's test).
      The strong Lucas-Selfridge test then returns N as a strong
      Lucas probable prime (slprp) if any of the following
      conditions is met: U_d=0, V_d=0, V_2d=0, V_4d=0, V_8d=0,
      V_16d=0, ..., etc., ending with V_{2^(s-1)*d}=V_{(N+1)/2}=0
      (all equalities mod N). Thus d is the highest index of U that
      must be computed (since V_2m is independent of U), compared
      to U_{N+1} for the standard Lucas-Selfridge test; and no
      index of V beyond (N+1)/2 is required, just as in the
      standard Lucas-Selfridge test. However, the quantity Q^d must
      be computed for use (if necessary) in the latter stages of
      the test. The result is that the strong Lucas-Selfridge test
      has a running time only slightly greater (order of 10 %) than
      that of the standard Lucas-Selfridge test, while producing
      only (roughly) 30 % as many pseudoprimes (and every strong
      Lucas pseudoprime is also a standard Lucas pseudoprime). Thus
      the evidence indicates that the strong Lucas-Selfridge test is
      more effective than the standard Lucas-Selfridge test, and a
      Baillie-PSW test based on the strong Lucas-Selfridge test
      should be more reliable. */

Tiger you need to add "-isysroot /Developer/SDKs/MacOSX10.4u.sdk").
Note that configure requires CFLAGS to contain a least one architecture that can
be run on the build machine (i.e. ppc on G3/G4, ppc or ppc64 on G5, ppc or i386
on Core and ppc, i386 or x86_64 on Core2/Xeon).
Universal builds of Tcl TEA extensions are also possible with CFLAGS set as
above, they will be [load]able by universal as well as thin binaries of Tcl.

- To enable weak-linking, set the MACOSX_DEPLOYMENT_TARGET environment variable
to the minimal OS version the binaries should be able to run on, e.g:
	export MACOSX_DEPLOYMENT_TARGET=10.4
This requires at least gcc 3.1; with gcc 4 or later, set/add to CFLAGS instead:
	export CFLAGS="-mmacosx-version-min=10.4"
Support for weak-linking was added with 8.4.14/8.5a5.

Detailed Instructions for building with macosx/GNUmakefile
----------------------------------------------------------

- Unpack the Tcl source release archive.

- The following instructions assume the Tcl source tree is named "tcl${ver}",
(where ${ver} is a shell variable containing the Tcl version number e.g. '9.0').

# ------------------------------------------------------------------------------
# (4) Define the base URLs used for testing.  Each must have a query string.
# ------------------------------------------------------------------------------
# - A HTTP/1.1 server is required.  It should be configured to provide
#   persistent connections when requested to do so, and to close these
#   connections if they are idle for one second.
# - The resource must be served with status 200 in response to a valid GET or
#   POST.
# - The value of "page" is always specified in the query-string. Different
#   resources for the three values of "page" allow testing of both chunked and
#   unchunked transfer encoding.
# - The variables "close" and "delay" may be specified in the query-string (for
#   a GET) or the request body (for a POST).
#   - "delay" is a numerical value in seconds, and causes the server to delay
#     the response, including headers.
#   - "close", if it has the value "y", instructs the server to close the
#     connection ater the current request.
# - Any other variables should be ignored.

# - duplicate    - the value of -pipeline does not matter if -keepalive 0
# - timeout1s    - tests that work correctly only if the server closes
#                  persistent connections after one second.
#
# Server timeout of persistent connections should be 1s.  Delays of 2s are
# intended to cause timeout.
# Servers are usually configured to use a longer timeout: this will cause the
# tests to fail.  The "2000" could be replaced with a larger number, but the

# ------------------------------------------------------------------------------
# (*) Notes on tests *.18*-testEof, *.19*-testEof - these test -repost 0
# ------------------------------------------------------------------------------
# These tests are a bit awkward because the main test kit analyses whether all
# requests are satisfied, with retries if necessary, and it has result analysis
# for processing retry logs.
# - *.18*-testEof tests that certain requests are NOT satisfied, so the analysis
#   is a one-off.
# - Tests *.18a-testEof depend on client/server timing - the test needs to call
#   http::geturl for all requests before the POST (request 2) is cancelled.
#   We test that requests 2, 3, 4 are all cancelled.
# - Other tests *.18*-testEof may not request 3 and 4 in time for the to be
#   added to the write queue before request 2 is completed. We simply check that
#   request 2 is cancelled.
# - The behaviour is different if all connections are allowed to time out
#   (label "j").  This case is not needed to test -repost 0, and is omitted.
# - Tests *.18*-normal and *.19* are conventional (-repost 0 should have no
#   effect).

# httpTest::TestOverlaps --
#
# The main test for correct behaviour of pipelined and sequential
# (non-pipelined) transactions.  Other tests should be run first to detect
# any inconsistencies in the data (e.g. absence of the elements that are
# examined here).
#
# Examine the sequence $someResults for each transaction from 1 to $n,
# ignoring any that are listed in $badTrans.
# Determine whether the elements "B" to $term for one transaction overlap
# elements "B" to $term for the previous and following transactions.
#
# Transactions in the list $badTrans are not included in "clean" or
# "dirty", but their possible overlap with other transactions is noted.
# Transactions in the list $notPiped are a subset of $badTrans, and
# their possible overlap with other transactions is NOT noted.
#
# Arguments:
# someResults - list of results, each of the form {letter numeral}
# n           - number of HTTP transactions
# term        - letter that indicated end of search range. "E" for testing
#               overlaps from start of request to end of response headers.
#               "F" to extend to the end of the response body.
# msg         - the cumulative message from sanity checks.  Append to it only
#               to report a test failure.
# badTrans    - list of transaction numbers not to be assessed as "clean" or
#               "dirty"
# notPiped    - subset of badTrans.  List of transaction numbers that cannot
#               taint another transaction by overlapping with it, because it
#               used a different socket.
#
# Return value: [list $msg $clean $dirty]
# msg   - warning messages: nothing will be appended to argument $msg if there
#         is an error with the test.
# clean - list of transactions that have no overlap with other transactions
# dirty - list of transactions that have YES overlap with other transactions

# ------------------------------------------------------------------------------
# "Package" httpTestScript for executing test scripts written in a convenient
# shorthand.
# ------------------------------------------------------------------------------

# ------------------------------------------------------------------------------
# Documentation for "package" httpTestScript.
# ------------------------------------------------------------------------------
# To use the package:
# (a) define URLs as the values of elements in the array ::httpTestScript
# (b) define a script in terms of the commands
#         START STOP DELAY KEEPALIVE WAIT PIPELINE GET HEAD POST
#     referring to URLs by the name of the corresponding array element.  The
#     script can include any other Tcl commands, and evaluates in the
#     httpTestScript namespace.
# (c) Use the command httpTestScript::runHttpTestScript to evaluate the script.
# (d) For tcltest tests, wrap the runHttpTestScript call in a suitable "test"
#     command.
# ------------------------------------------------------------------------------
# START
# Must be the first command of the script.
#
# STOP
# Must be present in the script to avoid waiting for client timeout.
# Usually the last command, but can be elsewhere to end a script prematurely.
# Subsequent httpTestScript commands will have no effect.
#
# DELAY ms
# If there are no WAIT commands, this sets the delay in ms between subsequent
# calls to http::geturl.  Default 500ms.
#
# KEEPALIVE
# Set the value passed to http::geturl for the -keepalive option.  The command
# applies to subsequent requests in the script. Default 1.
#
# WAIT ms
# Pause for a time in ms before sending subsequent requests.
#
# PIPELINE boolean
# Set the value of -pipeline using http::config.  The last PIPELINE command
# in the script applies to every request. Default 1.
#
# POSTFRESH boolean
# Set the value of -postfresh using http::config.  The last POSTFRESH command
# in the script applies to every request. Default 0.
#
# REPOST boolean
# Set the value of -repost using http::config.  The last REPOST command
# in the script applies to every request. Default 1 for httpTestScript.
# (Default value in http is 0).
#
# GET uriCode ?arg ...?
# Send a HTTP request using the GET method.
# Arguments:
# uriCode - the code for the base URI - the value must be stored in
#           ::httpTestScript::URL($uriCode).
# args    - strings that will be joined by "&" and appended to the query
#           string with a preceding "&".
#
# HEAD uriCode ?arg ...?
# Send a HTTP request using the HEAD method.
# Arguments: as for GET
#
# POST uriCode ?arg ...?
# Send a HTTP request using the POST method.
# Arguments:
# uriCode - the code for the base URI - the value must be stored in
#           ::httpTestScript::URL($uriCode).
# args    - strings that will be joined by "&" and used as the request body.

#
# This differs from the original string tests in that the tests call
# things in procs, which uses the compiled string code instead of
# the runtime parse string code.  The tests of import should match
# their equivalent number in string.test.

(c) Type "./configure". This runs a configuration script created by GNU
    autoconf, which configures Tcl for your system and creates a Makefile. The
    configure script allows you to customize the Tcl configuration for your
    site; for details on how you can do this, type "./configure --help" or
    refer to the autoconf documentation (not included here). Tcl's "configure"
    supports the following special switches in addition to the standard ones:

	--enable-threads	If this switch is set, Tcl will compile itself
				with multithreading support.
	--disable-load		If this switch is specified then Tcl will
				configure itself not to allow dynamic loading,
				even if your system appears to support it.
				Normally you can leave this switch out and Tcl
				will build itself for dynamic loading if your
				system supports it.
	--disable-dll-unloading	Disables support for the [unload] command even

 * TcpConnect --
 *
 *	This function opens a new socket in client mode.
 *
 *	This might be called in 3 circumstances:
 *	-   By a regular socket command
 *	-   By the event handler to continue an asynchroneous connect
 *	-   By the event handler to continue an asynchronously connect
 *	-   By a blocking socket function (gets/puts) to terminate the
 *	    connect synchroneously
 *	    connect synchronously
 *
 * Results:
 *      TCL_OK, if the socket was successfully connected or an asynchronous
 *      connection is in progress. If an error occurs, TCL_ERROR is returned
 *      and an error message is left in interp.
 *
 * Side effects:
 *	Opens a socket.
 *
 * Remarks:
 *	A single host name may resolve to more than one IP address, e.g. for
 *	an IPv4/IPv6 dual stack host. For handling asyncronously connecting
 *	an IPv4/IPv6 dual stack host. For handling asynchronously connecting
 *	sockets in the background for such hosts, this function can act as a
 *	coroutine. On the first call, it sets up the control variables for the
 *	two nested loops over the local and remote addresses. Once the first
 *	connection attempt is in progress, it sets up itself as a writable
 *	event handler for that socket, and returns. When the callback occurs,
 *	control is transferred to the "reenter" label, right after the initial
 *	return and the loops resume as if they had never been interrupted.
 *	For syncronously connecting sockets, the loops work the usual way.
