Tcl Extension Architecture (TEA) Sample Extension

2012-02-27  Jan Nijtmans <[email protected]>

	* configure:	Regenerated to use latest TEA tcl.m4.
	* <all>:        Purge RCS keywords.

2010-12-15  Stuart Cassoff  <[email protected]>

	* configure.in:	Upgrade to newer install-sh and use it.
	* Makefile.in:
	* configure:	Regenerated to use latest TEA tcl.m4.

2010-12-14  Stuart Cassoff  <[email protected]>

	* configure:	Regenerated to use latest TEA tcl.m4.
			Better building on OpenBSD.

2010-12-14  Stuart Cassoff  <[email protected]>

	* Makefile.in: Make .SUFFIXES work for more (BSD) make programs.

2010-12-14  Jan Nijtmans <nijtmans@users.sf.net>

	* configure: Regenerated to use latest TEA tcl.m4.
	This adds cross-compile support to UNIX and Win, and
	support for building 64-bit executables with mingw-w64
	build tools.

2010-09-14  Jeff Hobbs  <[email protected]>

	* Makefile.in (valgrind): add valgrind sample targets

2010-08-16  Jeff Hobbs  <[email protected]>

	* Makefile.in (PKG_CFLAGS): remove -DBUILD_sample as that is
	auto-defined in TEA 3.9
	* configure, configure.in: update TEA 3.9

2010-08-12  Jeff Hobbs  <[email protected]>

	* configure: update TEA 3.8
	* Makefile.in (VPATH): add macosx.

2010-08-11  Jeff Hobbs  <[email protected]>

	* configure, configure.in: TEA 3.8 update, just include tcl.m4,
	modify TEA_INIT version and run autoconf 2.59

2010-04-30  Donal K. Fellows  <[email protected]>

	* doc/sha1.n: [Bug 2994714]: Updated documentation formatting to more
	closely follow Tcl's best practice guidelines in many aspects.

2010-04-29  Jan Nijtmans <[email protected]>

	* doc/sha1.n [Enh 2788534]: add package require to doc

2010-04-23  Jan Nijtmans <[email protected]>

	* configure: Regenerated to use latest TEA tcl.m4.
	* [Bug 2782806]: sample package's test cases fail
	Always define BUILD_sample, even on UNIX.

2010-02-19  Stuart Cassoff  <[email protected]>

	* tcl.m4: Correct compiler/linker flags for threaded builds on OpenBSD.
	* configure: Regenerated to use latest TEA tcl.m4.

2010-01-19  Jan Nijtmans <[email protected]>

	* configure: Regenerated to use latest TEA tcl.m4.

2009-04-27  Jeff Hobbs  <[email protected]>

	* tcl.m4 (TEA_CONFIG_CFLAGS): harden the check to add _r to CC on AIX
	with threads.

2009-03-26  Jan Nijtmans <[email protected]>

	* configure: Regenerated to use latest TEA tcl.m4.

2009-03-20  Andreas Kupries <[email protected]>

	* configure: Regenerated to get my latest updates to tcl.m4 (See
	tclconfig/ChangeLog).

	NOTE: This pulled in an unexpected set of changes regarding
	SHLIB_VERSION and SHARED_LIB_SUFFIX, indicating that configure was not
	regenerated since some older change to tcl.m4.

2009-03-18  Stuart Cassoff  <[email protected]>

	* Makefile.in: [Bug 2429444]: Removed offending 'rm -f' line.

2009-03-11  Joe English  <[email protected]>

	* pkgIndex.tcl.in: [Bug 1960628]: use @PACKAGE_NAME@ instead of
	"Tclsha1".

2008-12-20  Daniel Steffen  <[email protected]>

	* Makefile.in: use INSTALL_LIBRARY instead of INSTALL_PROGRAM to
	install libraries, avoids breakage from tcl's install-strip when built
	as a bundled package.

2008-06-18  Pat Thoyts  <[email protected]eforge.net>

	* win/makefile.vc: Updated win build files. Added new option to
	* win/rules.vc:    nmakehlp to qualify a path name for use in setting
	* win/nmakehlp.c:  up paths for test.

2007-10-23  Jeff Hobbs  <[email protected]>

	*** Tagged tea-3-branch to start TEA 4 development on HEAD ***

	* Makefile.in: separate PKG_ENV parts from TCLSH/WISH_ENV parts to
	better allow 8.4 and 8.5 core variant testing.

.SH DESCRIPTION
.PP
SHA1 is NIST's Secure Hashing Algorithm (also known as Secure Hashing
Standard) with the minor modification that they proposed on 7/11/94.
.PP
Switches can be in any order.
.PP
Returns a sha1 digest in base 2 ** log2base ascii representation.
log2base defaults to 4, i.e., hex representation.
.PP
.nf
       \fBlog2base   length    chars\fR
         1          160      01            \fI(binary)\fR
         2           80      0..3
         3           54      0...7         \fI(octal)\fR
         4           40      0..9a..f      \fI(hex)\fR
         5           32      0..9a..v      
         6           27      0..9a..zA..Z_, 
.fi
.PP
(The characters in the digest string have been chosen to be usable in
filenames so that the sha1 command can be used, for example, to digest URLs
into shorter strings for filenames in a cache.)
.PP
In the \fB\-string\fR version, returns sha1 digest alone of \fIstring\fR.
.PP
In the \fB\-chan\fR version, returns list of 2 items: length of data in
\fIchanID\fR followed by sha1 digest of all data in \fIchanID\fR.
\fIChanID\fR is identifier returned from "\fBopen\fR" for example.  If
\fB\-copychan\fR is supplied, will also copy all data from \fIchanID\fR to
\fIcopychanID\fR.
.PP
In the third form, \fB\-init\fR returns a descriptor, \fB\-update\fR can be
called any number of times with that descriptor and returns the number of
bytes read, and \fB\-final\fR returns the result in the same form as the
standalone \fB\-chan\fR.

As this extension is built via the TEA facilities, a pkgIndex.tcl
file is provided for automatically. Instead of simply sourcing a
Tcl script, it will load the shared object or DLL that was built from
the C sources, roughly like:
[example {
   package ifneeded sample 1.0 [list load [file join $dir libsample.so]]
}]
or:
[example {
   package ifneeded sample 1.0 [list load [file join $dir sample.dll]]
}]
The TEA will create the pkgIndex.tcl file automatically via the
pkg_mkIndex command.


[section {Details on version numbers}]

   # __CHANGE__
   # Set your package name and version numbers here.  The NODOT_VERSION is
   # required for constructing the library name on systems that don't like
   # dots in library names (Windows).  The VERSION variable is used on the
   # other systems.
   #--------------------------------------------------------------------

   PACKAGE=sample

   MAJOR_VERSION=0
   MINOR_VERSION=5
   PATCHLEVEL=

   VERSION=${MAJOR_VERSION}.${MINOR_VERSION}${PATCHLEVEL}
   NODOT_VERSION=${MAJOR_VERSION}${MINOR_VERSION}
}]

So, the above would result in a macro VERSION with the value 0.5
[para]
The version number is also used to construct a distinguishing name for
the library, like: libsample0.5.so or sample05.dll.
This way there is much less chance of a conflict between versions.


[section {Subtleties with package names}]

There are a few things you must be aware of when choosing a name for
the extension:

initialisation routine. The precise rules are explained in the manual
page for the load command, but here are a few examples:
[example {
   Filename        Package name    Initial procedure
   foo.dll         foo             Foo_Init
   FOO.DLL         fOO             Foo_Init
   libFOO.so       fOO             Foo_Init
   libfoo1.2.so    fOo             Foo_Init
}]
So, in the index file you might see:
[example {
   package ifneeded fOo 1.2 [list load [file join $dir libfoo1.2.so]]
}]
A second issue is that for the extension to useful in a [emph safe]
interpreter, you need to define an initialisation routine with a name
like "Foo_SafeInit" (and possibly define the commands in another, safer,
way).

[para]
The third issue that we would like to bring under your attention is the
fact that under Windows you must explicitly indicate that a function in
a DLL is to made visible (exported) to the outside world. Without this
instruction the initialisation routine can not be loaded and therefore
loading the extension fails.

[para]
The sample extension contains this fragment of code (sample.h) to take
care of this (in general, the initialisation routine is the only one
that needs to be exported - all others should be defined as [emph static] to
reduce the chance of naming conflicts):
[example {
   /*
    * Windows needs to know which symbols to export.

    */

   #ifdef BUILD_sample
   #undef TCL_STORAGE_CLASS
   #define TCL_STORAGE_CLASS DLLEXPORT
   #endif /* BUILD_sample */

   ...

   /*
    * Only the _Init function is exported.
    */

   EXTERN int      Sample_Init _ANSI_ARGS_((Tcl_Interp * interp));
