Tcl extension: check Tcl version?
Is there a recommended way to check if a (binary) Tcl extension is loaded to the same Tcl version that was used for linking the extension? Currently I'm encountering a problem with an extension that I have built (and linked) with libtk8.3.so and that can be loaded under wish8.5 as well (without re-bulding, using package require). A number of newly provided commands work well in spite of the version mixture, but others don't, and wish8.5 crashes when these commands are used. Is this behavior normal, i.e. should I check that compile-time version and run-time version are identical? Or does this indicate some subtle coding problem? Thanks for any suggestions Olaf

Or does this > indicate some subtle coding problem? Not subtle. Major problem. DO NOT DO THAT. If you want to be loadable across multiple versions do NOT link with libtk directly, use the stubs table to do it, it was made for that usecase. (read about it on the wiki http://wiki.tcl.tk/stubs and http://www.tcl.tk/doc/howto/stubs.html) Michael

The recommended way is to use Tcl's stubs interfaces to produce
an extension that can be [load]ed into more than one minor release
of Tcl.

Since you're extending Tk as well, use Tk's stubs interfaces too.

From one minor release to the next, stubs-compatibility and
source compatibility (possibly with help of some #define's) are
what the Tcl/Tk developers aim to achieve.
There's no aim to maintain binary compatibility between the
shared libraries of different minor releases. That's why those
shared libraries are labeled with their version numbers (libtcl8.4.so
vs libtcl8.5.so, etc.). Lack of binary compatibility is likely to
show up as crashes, so yes your troubles are to be expected.
I strongly recommend you convert to using the stubs interfaces.
If for some reason you truly can't make that conversion, use the
"exact" flag of your Tcl_PkgRequire() calls in your extension to
force a match to the minor version(s) you compiled against:
int
Extension_Init(Tcl_Interp *interp) {
...
if (Tcl_PkgRequire(interp, "Tcl", TCL_VERSION, 1) == NULL) {
return TCL_ERROR;
}
...
if (Tcl_PkgRequire(interp, "Tk", TK_VERSION, 1) == NULL) {
return TCL_ERROR;
}
...
}

It's been politely pointed out to me that in my effort to simplify the
example for posting, I converted it into something that won't work with
Tcl/Tk 8.5 and later. Please use this example instead:
int
Extension_Init(Tcl_Interp *interp) {
...
if (Tcl_InitStubs(interp, TCL_VERSION, 1) == NULL) {
return TCL_ERROR;
}
...
if (Tk_InitStubs(interp, TK_VERSION, 1) == NULL) {
return TCL_ERROR;
}
...
}
This revised example is source compatible with Tcl/Tk header files from
version 8.5. And for programs still choosing to lock themselves to a
single minor release of Tcl and Tk, source compatibility is the kind
you want. Sorry about any confusion or grief.
The other benefit is that written this way, you are only a
-DUSE_TCL_STUBS -DUSE_TK_STUBS away from starting to use stubs, and
then only a s/1/0/g away from using stubs to produce [load]ability
into multiple minor releases of Tcl/Tk.

As you (and Michael) pointed out, using the stubs mechanism
is certainly the right thing to do and I'm currently trying
to modify the Init function and the makefile appropriately.
However, I do have a problem with pkg_mkIndex now. As soon as
I compile with Tk_InitStubs() (either with the conventional or
with the libtclstub/libtkstub libraries), pkg_mkIndex complains:
~$ wish8.3
pkg_mkIndex -verbose . my_ext.so
warning: error while loading my_ext.so: can't find package Tk 8.3
while directly loading the extension:
load ./my_ext.so
works.
The same behavior is seen under wish8.4 or wish8.5 if the
exact_flag is set to 0 (if it is set to 1, then pkg_mkIndex
correctly complains about non-matching versions).
Any more suggestions?
Thanks,
Olaf

Basically: Don't use pkg_mkIndex..., its not worth the trouble, it was
fine when lazy loading was still en vogue, but that time has passed...
The nearly generic line for your pkgIndex.tcl is trivial, so use that,
just add in the right version number.

Donald G Porter wrote: > $ wish8.3 > % pkg_mkIndex -load Tk -verbose . my_ext.so Oh, yeah, since you're working with such an outdated version of Tcl, you will probably want to explicitly use either the -direct or -lazy options, depending what sort of indexing you want.

I'm slightly surprised by this advise since I had the impression (from the Tcl 8.5 manpages) that pkg_mkIndex is still the recommended way to create index files (and it worked fine before I tried to use the stubs mechanism). But it's no problem to avoid pkg_mkIndex and to construct pkgIndex.tcl without pkg_mkIndex. > But, just to see how close to working you are, try this: > > $ wish8.3 > % pkg_mkIndex -load Tk -verbose . my_ext.so Perfect! Works as expected! Wouldn't it be reasonable to either update the documentation and to mention these limitations of pkg_mkIndex in combination with tcl-stubs, or to improve pkg_mkIndex such that it isn't confused by Tk_InitStubs()?

This is an announcement for a relatively new Tcl project: tcl-mp Tcl-mp is a Tcl interface to POSIX Message Queues*. It provides a Tcl package that allows scripts to create/open/close/unlink multiple parallel message queues, and to send/receive messages synchronously and asynchronously to/from them. * A POSIX message queue is an Inter-Process Communication mechanism available on Linux and some other POSIX-compliant operating systems. It allows to or more processes (or threads) to communicate under the same OS. The messages are buffered by the kernel, which gives them kernel persistency. A message queue can be thought of as a linked list of messages. Threads with adequate permission can put messages onto the queue, and threads with adequuate permission can remove messages from the queue. Each message is assigned a priority by the sender, and the oldest message of highest priority is always retrieved first. Unlike PIPES and FIFOS, no requirement exists that someone be waiting for a message to arrive on a queue, before some process writes a message to that queue. It's not even a requirement for both processes to exist at the same time.

Opening a TCL program from within another TCL program in ANSYS Tcl-Tk
Hi everyone, I have been pulling my hair with this one for a couple of days and still have not found a fix. I'm working within ANSYS Tcl-Tk implementation. I created a Tcl-Tk script that generates a simple window with three buttons. Each button opens another window which is created in a separate Tcl file. The second window have a lot of text entries, variables, procedures, etc. I can open the second Tcl file by itself and everything works as supposed, but when I open it using the button in the first window, it opens but any procedure called by the widgets on the second window are not found... Here's the deal... Since I'm working within the ANSYS implementation of Tcl-Tk, I'm actually using an ANSYS command to open the second window. The command I use is: ### ans_sendcommand ~eui,'source O:/mad_projects_2/ANSYS/Macros/ IBR_CAS.tcl' ### It actually sends a command back to ANSYS telling it to execute a Tcl command...

How Tcl speaks for itself and how Tcl is not spoken for...
Hello It's Friday and... well... Two things about Tcl going through my mind this week, a nice anecdote and a eyebrow-rising thing on Wikipedia: Anecdote: Until three months ago I worked in a scientific institue where I wrote much software in Tcl, especially a big Build and Report System, some tools for automatic checking of coding style and other things. Tcl had a bad reputation there (not because of me... they dropped Tcl before I started there in favour of Joy, then JavaScript and now Python) and besides me, there was only one co-worker who appearantly writes some small Tcl-Scripts to support other researchers in their work. To get completely rid of Tcl, they even started to reimplement all things, I wrote in Tcl in Python just to have it in a language, that most of them know (which is a good decision on the one hand, but on the other hand, I think, it would be better to simply learn Tcl ;-), which made me a little bit sad. Now there is a new collegue who has to maintain some of the things I wrote. Comming from Perl he wasn't exactly enthusiastic when he heard, that he must maintain my old code in such an obscure language.. Two weeks ago, I got mail from him. He's just studying a complex system of scripts that are used for a sandboxed build system for source code which comes from external untrusted source and must be compiled and tested. Of course it's written in Tcl (and some bash-Scripting). He told me, that although he has never looked at Tcl before,...

tcl-inotify: File & directory level notifications for Tcl. (extension)
This is an announcement for a relatively new Tcl project: tcl-inotify. Tcl-inotify is a Tcl interface to the linux kernel's inotify* service. It provides a Tcl package that enables Tcl scripts to monitor the file system changes at a file and directory level. A large number of file/directory actions can be monitored. A proc is executed asynchronously to notify for changes. * inotify is a Linux kernel subsystem that provides file system event notifications. It was written by John McCutchan with help from Robert Love and later Amy Griffis to replace dnotify. It was included in the mainline kernel starting from release 2.6.13, and could be compiled into 2.6.12 and possibly earlier releases by use of a patch.

tcl-mq: POSIX Message Queues for Tcl. (Tcl package)
This is an announcement for a relatively new Tcl project: tcl-mp Tcl-mp is a Tcl interface to POSIX Message Queues*. It provides a Tcl package that allows scripts to create/open/close/unlink multiple parallel message queues, and to send/receive messages synchronously and asynchronously to/from them. * A POSIX message queue is an Inter-Process Communication mechanism available on Linux and some other POSIX-compliant operating systems. It allows to or more processes (or threads) to communicate under the same OS. The messages are buffered by the kernel, which gives them kernel persistency. A message queue can be thought of as a linked list of messages. Threads with adequate permission can put messages onto the queue, and threads with adequuate permission can remove messages from the queue. Each message is assigned a priority by the sender, and the oldest message of highest priority is always retrieved first. Unlike PIPES and FIFOS, no requirement exists that someone be waiting for a message to arrive on a queue, before some process writes a message to that queue. It's not even a requirement for both processes to exist at the same time.

Opening a TCL program from within another TCL program in ANSYS Tcl-Tk
Hi everyone, I have been pulling my hair with this one for a couple of days and still have not found a fix. I'm working within ANSYS Tcl-Tk implementation. I created a Tcl-Tk script that generates a simple window with three buttons. Each button opens another window which is created in a separate Tcl file. The second window have a lot of text entries, variables, procedures, etc. I can open the second Tcl file by itself and everything works as supposed, but when I open it using the button in the first window, it opens but any procedure called by the widgets on the second window are not found... Here's the deal... Since I'm working within the ANSYS implementation of Tcl-Tk, I'm actually using an ANSYS command to open the second window. The command I use is: ### ans_sendcommand ~eui,'source O:/mad_projects_2/ANSYS/Macros/ IBR_CAS.tcl' ### It actually sends a command back to ANSYS telling it to execute a Tcl command... I know this is not pretty but its the only way i was able to make it at least show the window. ############################## #Main Tcl (excerpt): ############################## namespace eval Tools { proc IBRCambpell {} { #source O:/mad_projects_2/ANSYS/Macros/IBR_CAS.tcl ans_sendcommand ~eui,'source O:/mad_projects_2/ANSYS/Macros/ IBR_CAS.tcl' } proc viewManager {} { ans_sendcommand ~eui,'source O:/mad_projects_2/ANSYS/Macros/ ViewManager.tcl' } proc powerAnnotation {} { ans_sendcommand ~eui,'source ...

How Tcl speaks for itself and how Tcl is not spoken for...
Hello It's Friday and... well... Two things about Tcl going through my mind this week, a nice anecdote and a eyebrow-rising thing on Wikipedia: Anecdote: Until three months ago I worked in a scientific institue where I wrote much software in Tcl, especially a big Build and Report System, some tools for automatic checking of coding style and other things. Tcl had a bad reputation there (not because of me... they dropped Tcl before I started there in favour of Joy, then JavaScript and now Python) and besides me, there was only one co-worker who appearantly writes some small Tcl-Scripts to support other researchers in their work. To get completely rid of Tcl, they even started to reimplement all things, I wrote in Tcl in Python just to have it in a language, that most of them know (which is a good decision on the one hand, but on the other hand, I think, it would be better to simply learn Tcl ;-), which made me a little bit sad. Now there is a new collegue who has to maintain some of the things I wrote. Comming from Perl he wasn't exactly enthusiastic when he heard, that he must maintain my old code in such an obscure language.. Two weeks ago, I got mail from him. He's just studying a complex system of scripts that are used for a sandboxed build system for source code which comes from external untrusted source and must be compiled and tested. Of course it's written in Tcl (and some bash-Scripting). He told me, that although he has never looked at Tcl before,...

Extending TCL in C with tcl.h - Disabliing [<tcl-cmd>] feature
Hi, TCL has a command execution syntax like this: [<tcl cmd>] Anything inside the 3rd bracket will be executed as a Tcl command by the Tcl interprater. Is there any way I can disable/delete this Tcl construct [ <tcl-cmd>]? In other words, my Tcl interprator should print "[32]" for tcl command puts "[32]" It should not try to treat [] as a special character. Is this any way possible while extending Tcl in C with tcl.h? Thank you, Arijit * arijit79@gmail.com | puts "[32]" | | It should not try to treat [] as a special character.

tcl-inotify: File & directory level notifications for Tcl. (extension)
This is an announcement for a relatively new Tcl project: tcl-inotify. Tcl-inotify is a Tcl interface to the linux kernel's inotify* service. It provides a Tcl package that enables Tcl scripts to monitor the file system changes at a file and directory level. A large number of file/directory actions can be monitored. A proc is executed asynchronously to notify for changes. * inotify is a Linux kernel subsystem that provides file system event notifications. It was written by John McCutchan with help from Robert Love and later Amy Griffis to replace dnotify. It was included in the mainline kernel starting from release 2.6.13, and could be compiled into 2.6.12 and possibly earlier releases by use of a patch. Its function is essentially an extension to filesystems to notice changes to the filesystem, and report those changes to applications.
