A NOTE ON THE CHANGELOG:
Starting in early 2011, Tcl source code has been under the management of
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.

README:  Tcl
    This is the Tcl 8.6.9 source distribution.
	http://sourceforge.net/projects/tcl/files/Tcl/
    You can get any source release of Tcl from the URL above.

Contents
--------
    1. Introduction
    2. Documentation

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:

	http://core.tcl-lang.org/

Tcl/Tk release and mailing list services are hosted by SourceForge:

	http://sourceforge.net/projects/tcl/

with the Tcl Developer Xchange hosted at:

	http://www.tcl-lang.org/

Tcl is a freely available open source package.  You can do virtually
anything you like with it, such as modifying it, redistributing it,
and selling it either in whole or in part.  See the file
"license.terms" for complete information.

2. Documentation
----------------

Extensive documentation is available at our website.
The home page for this release, including new features, is
	http://www.tcl-lang.org/software/tcltk/8.6.html

Detailed release notes can be found at the file distributions page
by clicking on the relevant version.
	http://sourceforge.net/projects/tcl/files/Tcl/

Information about Tcl itself can be found at
	http://www.tcl-lang.org/about/

There have been many Tcl books on the market.  Many are mentioned in the Wiki:
	http://wiki.tcl-lang.org/_/ref?N=25206

To view the complete set of reference manual entries for Tcl 8.6 online,
visit the URL:
	http://www.tcl-lang.org/man/tcl8.6/

2a. Unix Documentation
----------------------

The "doc" subdirectory in this release contains a complete set of
reference manual entries for Tcl.  Files with extension ".1" are for
programs (for example, tclsh.1); files with extension ".3" are for C

3. Compiling and installing Tcl
-------------------------------

There are brief notes in the unix/README, win/README, and macosx/README about
compiling on these different platforms.  There is additional information
about building Tcl from sources at

	http://www.tcl-lang.org/doc/howto/compile.html

4. Development tools
---------------------------

ActiveState produces a high quality set of commercial quality development
tools that is available to accelerate your Tcl application development.
Tcl Dev Kit builds on the earlier TclPro toolset and provides a debugger,

see the "Support and bug fixes" section below.

6. Tcl'ers Wiki
---------------

A Wiki-based open community site covering all aspects of Tcl/Tk is at:

	http://wiki.tcl-lang.org/

It is dedicated to the Tcl programming language and its extensions.  A
wealth of useful information can be found there.  It contains code
snippets, references to papers, books, and FAQs, as well as pointers to
development tools, extensions, and applications.  You can also recommend
additional URLs by editing the wiki yourself.

8. Support and Training
------------------------

We are very interested in receiving bug reports, patches, and suggestions
for improvements.  We prefer that you send this information to us as
tickets entered into our tracker at:

	http://core.tcl-lang.org/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,
see the following Web site for links to other organizations that offer
Tcl/Tk training:

	http://wiki.tcl-lang.org/training

9. Tracking Development
-----------------------

Tcl is developed in public.  To keep an eye on how Tcl is changing, see
	http://core.tcl-lang.org/

10. Thank You
-------------

We'd like to express our thanks to the Tcl community for all the
helpful suggestions, bug reports, and patches we have received.
Tcl/Tk has improved vastly and will continue to do so with your help.

\fBTcl_ExternalToUtf\fR.
.PP
\fBTcl_WinUtfToTChar\fR and \fBTcl_WinTCharToUtf\fR are
Windows-only convenience
functions for converting between UTF-8 and Windows strings
based on the TCHAR type which is by convention
a Unicode character on Windows NT.




.PP
\fBTcl_GetEncodingName\fR is roughly the inverse of \fBTcl_GetEncoding\fR.
Given an \fIencoding\fR, the return value is the \fIname\fR argument that

\fBTcl_GetEncodingName\fR is only guaranteed to persist until the

.SH DESCRIPTION
.PP
These functions provide an interface to the function stack that an interpreter
iterates through to evaluate commands.  The routine behind a command is
implemented by an initial function and any additional functions that the
routine pushes onto the stack as it progresses.  The interpreter itself pushes
functions onto the stack to react to the end of a routine and to exercise other
forms of control such as switching between in-progress stacks and the
evaluation of other scripts at additional levels without adding frames to the C
stack.  To execute a routine, the initial function for the routine is called
and then a small bit of code called a \fItrampoline\fR iteratively takes

functions off the stack and calls them, using the value of the last call as the
value of the routine.
.PP







\fBTcl_NRCallObjProc\fR calls \fInreProc\fR using a new trampoline.





.PP
\fBTcl_NRCreateCommand\fR, an alternative to \fBTcl_CreateObjCommand\fR,



resolves \fIcmdName\fR, which may contain namespace qualifiers, relative to the
current namespace, creates a command by that name, and returns a token for the
command which may be used in subsequent calls to \fBTcl_GetCommandName\fR.


Except for a few cases noted below any existing command by the same name is
















first deleted.  If \fIinterp\fR is in the process of being deleted
\fBTcl_NRCreateCommand\fR does not create any command, does not delete any
command, and returns NULL.
.PP
\fBTcl_NREvalObj\fR pushes a function that is like \fBTcl_EvalObjEx\fR but
consumes no space on the C stack.




.PP





\fBTcl_NREvalObjv\fR pushes a function that is like \fBTcl_EvalObjv\fR but
consumes no space on the C stack.
.PP
\fBTcl_NRCmdSwap\fR is like \fBTcl_NREvalObjv\fR, but uses \fIcmd\fR, a token


previously returned by \fBTcl_CreateObjCommand\fR or


\fBTcl_GetCommandFromObj\fR, instead of resolving the first word of \fIobjv\fR.
.  The name of this command must be the same as \fIobjv[0]\fR.


.PP
\fBTcl_NRExprObj\fR pushes a function that evaluates \fIobjPtr\fR as an


expression in the same manner as \fBTcl_ExprObj\fR but without consuming space
on the C stack.



.PP
All of the functions return \fBTCL_OK\fR if the evaluation of the script,
command, or expression has been scheduled successfully.  Otherwise (for example

if the command name cannot be resolved), they return \fBTCL_ERROR\fR and store
a message as the interpreter's result.
.PP
\fBTcl_NRAddCallback\fR pushes \fIpostProcPtr\fR.  The signature for



\fBTcl_NRPostProc\fR is:
.PP
.CS
typedef int
\fBTcl_NRPostProc\fR(
        \fBClientData\fR \fIdata\fR[],
        \fBTcl_Interp\fR *\fIinterp\fR,
        int \fIresult\fR);
.CE
.PP



\fIdata\fR is a pointer to an array containing \fIdata0\fR through \fIdata3\fR.



\fIresult\fR is the value returned by the previous function implementing part



the routine.



.SH EXAMPLE
.PP
The following command uses \fBTcl_EvalObjEx\fR, which consumes space on the C

stack, to evalute a script:
.PP
.CS
int
\fITheCmdOldObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,

    return result;
}
\fBTcl_CreateObjCommand\fR(interp, "theCommand",
        \fITheCmdOldObjProc\fR, clientData, TheCmdDeleteProc);
.CE
.PP
To avoid consuming space on the C stack, \fITheCmdOldObjProc\fR is renamed to
\fITheCmdNRObjProc\fR and the postprocessing step is split into a separate

function, \fITheCmdPostProc\fR, which is pushed onto the function stack.
\fITcl_EvalObjEx\fR is replaced with \fITcl_NREvalObj\fR, which uses a
trampoline instead of consuming space on the C stack.  A new version of

\fITheCmdOldObjProc\fR is just a a wrapper that uses \fBTcl_NRCallObjProc\fR to
call \fITheCmdNRObjProc\fR:







.PP



.CS

\fITheCmdOldObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,

The \fBincr\fR command first gets an integer from \fIx\fR's value
by calling \fBTcl_GetIntFromObj\fR.
This procedure checks whether the value is already an integer value.
Since it is not, it converts the value
by setting the value's internal representation
to the integer \fB123\fR

Both representations are now valid.

.SH NAME
Tcl_ParseArgsObjv \- parse arguments according to a tabular description
.SH SYNOPSIS
.nf

As noted above, the \fItype\fR field is used to describe the interpretation of
the argument's value. The following values are acceptable values for
\fItype\fR:
.TP
\fBTCL_ARGV_CONSTANT\fR
.
The argument does not take any following value argument. If this argument is
present, the \fIsrcPtr\fR field (casted to \fIint\fR) is copied to the variable
pointed to by the \fIdstPtr\fR field. The \fIclientData\fR field is ignored.
.TP
\fBTCL_ARGV_END\fR
.
This value marks the end of all option descriptors in the table. All other
fields are ignored.
.TP
\fBTCL_ARGV_FLOAT\fR

value may then be passed back to one of \fBTcl_RestoreInterpState\fR
or \fBTcl_DiscardInterpState\fR, depending on whether the interp
state is to be restored.  So long as one of the latter two routines
is called, Tcl will take care of memory management.
.PP
The second triplet stores the snapshot of only the interpreter
result (not its complete state) in memory allocated by the caller.
These routines are passed a pointer to \fBTcl_SavedResult\fR
that is used to store enough information to restore the interpreter result.
\fBTcl_SavedResult\fR can be allocated on the stack of the calling
procedure.  These routines do not save the state of any error
information in the interpreter (e.g. the \fB\-errorcode\fR or
\fB\-errorinfo\fR return options, when an error is in progress).
.PP
Because the routines \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR perform
a superset of the functions provided by the other routines,

.AS int ch
.AP int ch in

.BE

.SH DESCRIPTION
.PP
All of the routines described examine Unicode characters and return a
boolean value. A non-zero return value means that the character does
belong to the character class associated with the called routine. The
rest of this document just describes the character classes associated
with the various routines.




.SH "CHARACTER CLASSES"

.SH ARGUMENTS
.AS "const Tcl_UniChar" *uniPattern in/out
.AP char *buf out
Buffer in which the UTF-8 representation of the Tcl_UniChar is stored.  At most
\fBTCL_UTF_MAX\fR bytes are stored in the buffer.
.AP int ch in
The Unicode character to be converted or examined.
.AP Tcl_UniChar *chPtr out
Filled with the Tcl_UniChar represented by the head of the UTF-8 string.

.AP "const char" *cs in
Pointer to a UTF-8 string.
.AP "const char" *ct in

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.
.TP
\fB%a\fR
On output, receives an abbreviation (\fIe.g.,\fR \fBMon\fR) for the day

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
\fBdeletemethod\fI name\fR ?\fIname ...\fR?
.
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
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).
.TP
\fBdestructor\fI bodyScript\fR

.QW \fB@\0\fIfileId\fR
notation, does not work.  When reading from a socket, a 16-bit DOS
application will hang and a 32-bit application will return immediately with
end-of-file.  When either type of application writes to a socket, the
information is instead sent to the console, if one is present, or is
discarded.
.RS
.PP
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.
But it works properly with an executable (using CommandLineToArgv, etc).
.PP
The Tk console text widget does not provide real standard IO capabilities.
Under Tk, when redirecting from standard input, all applications will see an
immediate end-of-file; information redirected to standard output or standard
error will be discarded.

.SH DESCRIPTION
.PP
The \fBhttp\fR package provides the client side of the HTTP/1.1
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.

\fB\-accept\fR \fImimetypes\fR
.
The Accept header of the request.  The default is */*, which means that
all types of documents are accepted.  Otherwise you can supply a
comma-separated list of mime type patterns that you are
willing to receive.  For example,
.QW "image/gif, image/jpeg, text/*" .
.TP
\fB\-pipeline\fR \fIboolean\fR
.
Specifies whether HTTP/1.1 transactions on a persistent socket will be
pipelined.  See the \fBPERSISTENT SOCKETS\fR section for details. The default
is 1.
.TP
\fB\-postfresh\fR \fIboolean\fR
.
Specifies whether requests that use the \fBPOST\fR method will always use a
fresh socket, overriding the \fB-keepalive\fR option of
command \fBhttp::geturl\fR.  See the \fBPERSISTENT SOCKETS\fR section for details.
The default is 0.
.TP
\fB\-proxyhost\fR \fIhostname\fR
.
The name of the proxy host, if any.  If this value is the
empty string, the URL host is contacted directly.
.TP
\fB\-proxyport\fR \fInumber\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.
.TP
\fB\-urlencoding\fR \fIencoding\fR
.
The \fIencoding\fR used for creating the x-url-encoded URLs with
\fB::http::formatQuery\fR and \fB::http::quoteString\fR.
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
\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.  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;

.CS
Pragma: no-cache
.CE
.RE
.TP
\fB\-keepalive\fR \fIboolean\fR
.
If boolean \fBtrue\fR, attempt to keep the connection open for servicing
multiple requests.  Default is 0.
.TP
\fB\-method\fR \fItype\fR
.
Force the HTTP request method to \fItype\fR. \fB::http::geturl\fR will
auto-select GET, POST or HEAD based on other options, but this option
enables choices like PUT and DELETE for webdav support.

\fB::http::formatQuery\fR \fIkey value\fR ?\fIkey value\fR ...?
.
This procedure does x-url-encoding of query data.  It takes an even
number of arguments that are the keys and values of the query.  It
encodes the keys and values, and generates one string that has the
proper & and = separators.  The result is suitable for the
\fB\-query\fR value passed to \fB::http::geturl\fR.
.TP
\fB::http::quoteString\fR \fIvalue\fR
.
This procedure does x-url-encoding of string.  It takes a single argument and
encodes it.
.TP
\fB::http::reset\fR \fItoken\fR ?\fIwhy\fR?
.
This command resets the HTTP transaction identified by \fItoken\fR, if any.
This sets the \fBstate(status)\fR value to \fIwhy\fR, which defaults to
\fBreset\fR, and then calls the registered \fB\-command\fR callback.

\fB::http::registerError\fR \fIport\fR ?\fImessage\fR?
.
This procedure allows a registered protocol handler to deliver an error
message for use by \fBhttp\fR.  Calling this command does not raise an
error. The command is useful when a registered protocol detects an problem
(for example, an invalid TLS certificate) that will cause an error to
propagate to \fBhttp\fR.  The command allows \fBhttp\fR to provide a
precise error message rather than a general one.  The command returns the
value provided by the last call with argument \fImessage\fR, or the empty
string if no such call has been made.
.TP
\fB::http::unregister\fR \fIproto\fR
.
This procedure unregisters a protocol handler that was previously

the default port and handler command that was previously installed
(via \fB::http::register\fR) if there was such a handler, and an error if

.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.

.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 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.

.PP
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 element specified by \fIfirst\fR
with no elements being deleted.
.PP
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.

.SH EXAMPLES
.PP
Replacing an element of a list with another:
.PP
.CS
% \fBlreplace\fR {a b c d e} 1 1 foo
a foo c d e

.CS
proc lremove {listVariable value} {
    upvar 1 $listVariable var
    set idx [lsearch -exact $var $value]
    set var [\fBlreplace\fR $var $idx $idx]
}
.CE
.PP
.VS TIP505
Appending elements to the list; note that \fBend+2\fR will initially
be treated as if it is \fB6\fR here, but both that and \fB12345\fR are greater
than the index of the final item so they behave identically:
.PP
.CS
% set var {a b c d e}
a b c d e
% set var [\fBlreplace\fR $var 12345 end+2 f g h i]
a b c d e f g h i

.PP
.CS

a list of return codes that may be accepted from evaluation of the
\fB\-body\fR script.  If evaluation of the \fB\-body\fR script returns
a code not in the \fIexpectedCodeList\fR, the test fails.  All
return codes known to \fBreturn\fR, in both numeric and symbolic
form, including extended return codes, are acceptable elements in
the \fIexpectedCodeList\fR.  Default value is
.QW "\fBok return\fR" .
.TP
\fB\-errorCode \fIexpectedErrorCode\fR
.
The optional \fB\-errorCode\fR attribute supplies \fIexpectedErrorCode\fR,
a glob pattern that should match the error code reported from evaluation of the
\fB\-body\fR script.  If evaluation of the \fB\-body\fR script returns
a code not matching \fIexpectedErrorCode\fR, the test fails.  Default value is
.QW "\fB*\fR" .
If \fB\-returnCodes\fR does not include \fBerror\fR it is set to \fBerror\fR.
.PP
To pass, a test must successfully evaluate its \fB\-setup\fR, \fB\-body\fR,
and \fB\-cleanup\fR scripts.  The return code of the \fB\-body\fR script and
its result must match expected values, and if specified, output and error
data from the test must match expected \fB\-output\fR and \fB\-errorOutput\fR
values.  If any of these conditions are not met, then the test fails.
Note that all scripts are evaluated in the context of the caller

.IP \(bu
the average amount of time required per iteration, in microseconds ([\fBlindex\fR $result 0])
.IP \(bu
the count how many times it was executed ([\fBlindex\fR $result 2])

the estimated rate per second ([\fBlindex\fR $result 4])

the estimated real execution time without measurement overhead ([\fBlindex\fR $result 6])
.PP
Time is measured in elapsed time using the finest timer resolution as possible,
not CPU time.
This command may be used to provide information as to how well the script or a
tcl-command is performing and can help determine bottlenecks and fine-tune
application performance.
.TP
\fI-calibrate\fR
.
To measure very fast scripts as exact as posible the calibration process
may be required.

The \fI-calibrate\fR option is used to calibrate timerate, 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.
.TP
\fI-overhead double\fR
.
The \fI-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.
.TP
\fI-direct\fR
.
The \fI-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 \fI-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 EXAMPLE
