There are several SEGv fixes in there

Add generic/itkDecls.h to list of itk4.0.0 headers that are installed

Alan W. Irwin — Sat, 09 Nov 2013 19:55:23 -0000

Without this patch compilation of C code that #includes itk.h fails since that header #includes itkDecls.h.

#52 Support both Itk and itk package names for itk-4.0.0

Alan W. Irwin — Fri, 08 Nov 2013 00:50:36 -0000

The comparisons in the title of this patch and in the text should be "Itk" versus "itk" and "Itcl" versus "itcl". (For some strange reason sourceforge lower-cased the leading "I" characters in my initial submit of the title and explanatory text for this patch.)

Support both Itk and itk package names for itk-4.0.0

Alan W. Irwin — Fri, 08 Nov 2013 00:42:23 -0000

Both

package require itcl

and

package require Itcl

work for itcl-4.0.0. This small patch gives the same "itk" and Itk capability to itk-4.0.0, i.e., adds the "Itk" package name to the existing "itk" package name. Some packages that use "package require Itk" inside will not work without the current patch.

constify Itcl stub table

Jan Nijtmans — Sat, 23 Jul 2011 20:25:35 -0000

Since Tcl/Tk 8.6, all stub tables are const, which means that the
compiler/linker protects them from being modified, It also means
that startup is faster, because during initialization no copy needs
to be made for each running Itcl instance: there is only one copy
of the stub tables which is shared by all instances.

The attached patch brings Itcl 4.0 up to date with Tcl 8.6 in
this respect, in the following way:
- copied ttkGenStubs.tcl from Tk8.6 to Itcl's tools/genStubs.tcl.
- Adds "const" in some places, to make the compiler happy.

ttkGenStubs.tcl comes originally from the same source
as tools/genStubs.tcl from Itcl 4, but has the following
improvements:
- constify the stub tables
- remove some unneeded #ifdef'ery
- better formatting of itcl*Decls.h
Apart from that, it is fully compatible and has all
features of tools/genStubs.tcl, so it is almost a
perfect replacement.

Regards,
Jan Nijtmans

Bump to 4.0b5

Don Porter — Thu, 12 Aug 2010 17:09:49 -0000

Attached is patch upgrading to TEA 3.8 and
then bumping the release number to Itcl 4.0b5.

Aim is to get an updated release ready to bundle
with Tcl 8.6b2.

Itcl 4.0 MODULE_SCOPE/static/const stubs pointers

Jan Nijtmans — Thu, 29 Apr 2010 14:55:03 -0000

In Tcl 8.6, visibility of stub pointers is
adapted to assure that extensions cannot
modify anything in the stubs table. This
patch provides the same feature for Itcl.

genStubs.tcl is modified to make itclStubs
"MODULE_SCOPE const"; itclIntStubs and
tclStubHooks "static const". The itclStubAPI
is no longer necessary.

Further on, the Itcl_InitStubs macro was
previously defined as:
#define Itcl_InitStubs(interp, version, exact) Itcl_InitStubs( \ interp, ITCL_PATCH_LEVEL, 1)
or, in other words, Itcl_InitStubs is a macro which maps
to a function with the same name. It makes "version"
and "exact" just dummy parameters, but I don't find
that anywhere in the documentation. Therefore, I
suspect that was not intended.

Here is the patch, fixing all that.

Fix Itcl 4.0 warnings and errors on various platforms

Jan Nijtmans — Thu, 29 Apr 2010 10:58:08 -0000

Tried to compile Itcl 4.0b4 (as in Tcl 8.6 HEAD) on
win32 and linux (MSVC, MINGW, CYGWIN), and
collected everything needed to make it compile
without warnings on those platforms. I beleave
this addresses some warnings already seen bij
Larry Virden on sparc solaris 8 as well.

Explanation:
- various unnecessary includes, e.g. itclInt.h already
includes "tcl.h" and "itcl.h" and itclInt includes
<string.h> and <ctype.h> so itcl.h does not need
to do that.
- <unistd.h> does not exist and is not needed on win32.
- Use TEOV_callback * and Tcl_NRPostProc * as
function parameters in stead of void *, so we don't
need type casts. I believe this fixes some of the
warnings reported by Larry Virden
- Always define BUILD_itcl, so CYGWIN/unix can
make use of it as well.
- dllEntryPoint.c does not end in a newline, some
versions of gcc complain about that.
- use the UCHAR macro in all isupper()-like function
calls.
- Fixed some "statement not reached" warnings

Remark: Compilation on CYGWIN requires an update
to the latest tcl.m4 and re-generate the configure script.
That change is not included in this patch.

calling Itcl_library for embedded MacOS Tcl

Zbigniew Diaczyszyn — Mon, 19 Apr 2010 09:00:35 -0000

I have taken the package Itcl 3.4 in the folder /System/Library/Tcl/8.5/itcl3.4 from AS 8.5.8.1 for MacOSX and put it in the lib folder of my standalone application with an embedded Wish. After modifying the variable auto_path to my application's lib folder the command <package require Itcl> will result in an error complaining that there is no itcl.tcl in the known lib pathes.

I suggest to put the following line into the pkgIndex.tcl like in Linux teacup version of Itcl 3.4:

set ::env(ITCL_LIBRARY) $dir

free Tcl from Itcl hacks (1)

miguel sofer — Wed, 06 Aug 2008 14:31:59 -0000

Tcl has some hacky code in ::unknown to handle Itcl's nonstandard handling of scoped scripts. This should be migrated to itcl.tcl instead, so that Tcl can be freed from this wart. This patch does this "the cheap way", by editing ::unknown on loading Itcl. The good way would of course be to avoid the requisite for nonstandard handling.
