enable-threads with multi-threaded/multi-interp app but w/o tcl thread api?
Ive been searching for an answer to a basic question and have been unable to find it : If I have a multi-threaded C++ application with embedded tcl, using pthreads and each thread having its own tcl interpreter, do I need to build the tcl library with threads enabled? I am not using the TCL thread API, I am simply creating and using multiple tcl interpreters within separate pthreads(again, each thread having its own interp). From the Wiki ( http://wiki.tcl.tk/1339 ) Some consolidated rules for embedding Tcl in a threaded application: * You can NEVER use the same interpreter from more than one thread * If you only have one Tcl Interpreter: * You can use either Unthreaded or Threaded Tcl * No "Big Global Mutex" is required for Unthreaded Tcl Build (Never required for Threaded Tcl build) * If you have Multiple Tcl Interpreters: * If you are using an Unthreaded Tcl a "Big Global Mutex" is required for ALL calls to functions in libtcl * If you are using a Threaded Tcl, no mutex locks are required You are responsible for the "big global mutex" if you have multiple Tcl interpreters "owned" by multiple threads and unthreaded Tcl. Thanks, Roy Keene ...

I don't know the answer, but why do you want to avoid the threaded build? Do you fear its getting slower due to additional locks? An advantage of using Tcl instead of pthreads directly (i.e., Tcl_CreateThread() and friends), you gain the advantage of platform independence, which means mainly Windows. Tcls thread API in the C level mostly corresponds to pthreads. Of course, to use these functions, you must have a threaded build. IIRC there was only one reason to avoid the threaded build on Unix, namely fork() Christian Thank you for the response. This is for an existing application that uses pthreads extensively. It will only be imp...

tcl-gaul: Genetic Algorithms for Tcl. (Tcl package)
This is an announcement for a relatively new Tcl project: tcl-gaul Tcl-gaul is a Tcl extension for genetic/evolutionary algorithm processing.It relies on the GAUL library: http://gaul.sourceforge.net/ * A genetic algorithm (GA) is a search technique used in computing to find exact or approximate solutions to optimization and search problems.

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 to compile tcl or encrypt tcl
I use TclPro1.5 to compile my tcl script with tixwish in the Solaris before. But I cannot use the same method in Linux. Why? Is there any utility for me to compile or encrypt the code by using tixwish? The following is the simple code if I use the tixwish: #!/home/albertl/local/bin/tixwish puts "haha" And after using procomp by the TclPro1.5 Error in startup script: The TclPro ByteCode Loader is not available or does not support the correct version while executing "error "The TclPro ByteCode Loader is not available or does not support the correct version"" invoked from within "if {[catch {package require tbcload 1.3} err] == 1} { error "The TclPro ByteCode Loader is not available or does not support the correct version" ...."

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?

TCL is not thread safer in TCL 8.3 or 8.4... Any plans to fix this?
It is a shame that I can't upgrade one of my applications due to this problem, though the memory leaks also intorduced in 8.3 and 8.4 are problem as well. :( I have a process that spawn a configurable number of thread with a TCL intrepeter in each one. The interps are isolated and do not communicate or share anything withe each other. Each thread is a rule processor that is handed TCL scripts based on what events occurs within a multi process enviroment rnaing across the whole itnerprize... Works great with TCL 8.2, not a single problem... But with TCL 8.3 and TCL 8.4 we get quite a few run time errors and/or data corruption and core dumps that all leads back to TCL. :( Quite a shame! cwhooks@landacorp.com wrote: > It is a shame that I can't upgrade one of my applications due to this > problem, though the memory leaks also intorduced in 8.3 and 8.4 are > problem as well. :( What are the bug report ID numbers of the issues giving you trouble? -- | Don Porter Mathematical and Computational Sciences Division | | donald.porter@nist.gov Information Technology Laboratory | | http://math.nist.gov/~DPorter/ NIST | |______________________________________________________________________| Don Porter <dgp@email.nist.gov> wrote: > cwhooks@landacorp.com wrote: >> It is a shame that I can't upgrade one of my applications due to this >> problem, though the memory leaks also intorduced ...
