newbee cvs question
by Peter Lundqvist (disjunkt) ＠ Pike (-) developers forum 25 Oct '03

25 Oct '03

Ok, so I'm about to do my first commit to cvs. It's been a while since I've used cvs other than localy, so I thought it'd be a good idea to ask a few questions first. I've never used cvs over ssh before - but I guess this ought to be the suitable thing for my bash-environment? export CVSROOT=:ext:username@pike.ida.liu.se:/cvs exprot CVS_RSH=ssh Do I need to check out a fresh tree using my username or can I continue with the anonymous tree that I've kept? Sorry for beeing lame.

mmx.h
by Mirar ＠ Pike developers forum 25 Oct '03

25 Oct '03

http://www.mirar.org/mmx.h.txt in case it's lost. :) Anyone that can figure out the license? /* mmx.h MultiMedia eXtensions GCC interface library for IA32. To use this library, simply include this header file and compile with GCC. You MUST have inlining enabled in order for mmx_ok() to work; this can be done by simply using -O on the GCC command line. Compiling with -DMMX_TRACE will cause detailed trace output to be sent to stderr for each mmx operation. This adds lots of code, and obviously slows execution to a crawl, but can be very useful for debugging.

mmx.h
by Johan Sundstr�m, Lysator ＠ Pike developers forum 25 Oct '03

25 Oct '03

I just received word from a (more) Gentoo person (than me) that it is worth looking for mmx.h as <asm/mmx.h>, in the pike configure scripts. Just posting a note here to make it less probable that it instantly gets forgotten about. :-)

CVS question
by Bill Welliver 24 Oct '03

24 Oct '03

I'm doing some with the SMTP code that David Gourdelier submitted to CVS, and I've got a logistics question. There are now a number of relatively different classes inside of that module, and I thought it would benefit from being split into multiple code files. The problem is that I need to delete the file SMTP.pmod and replace it with a directory of the same name. Is that going to create problems for people that already have the tree checked out (don't remember if I've ever done this myself). I won't do this until someone gives the OK on that, lest I create real problems. Bill

autoconf macros for pike
by Bill Welliver 24 Oct '03

24 Oct '03

I made some changes to the autoconf macro that is used to find a pike. It seems to work a little bit better, though it has one shortcoming I'd like to fix: if you specify a pike that's actually a symlink to another, it won't follow the symlink to determine what the actual filename is. This creates a problem when you install a new version of pike (which is a relatively common occurrence), and things stop working because the version has changed: /usr/local/bin/pike is actually /usr/local/pike/ver/bin/pike. Any thoughts about this? -- Specifically, I made some portability changes and added the ability to check for minimum and maximum pike versions. This macro makes it easier to get pike modules set up, as it sets a number of autoconf substitutions. Example in a configure.in/ac when this file is stored as aclocal.m4 in your project directory: AP_CHECK_PIKE(7.4.1, 7.4.999) to check for a version of pike that's between 7.4.1 and 7.4.999, and make sure it has a C include directory (where the headers and compile tools live). It sets the following variables/substitutions: PIKE - path to pike PIKE_VERSION - version of pike found (ie 7.4.10) PIKE_INCLUDE_DIRS - string to includes (ie -I /usr/local/pike/7.4.10/include/pike) PIKE_MODULE_DIR - path to pike modules directory (ie /usr/local/pike/7.4.10/lib/modules)0 I'd like to get some feedback on this, along with other suggestions for easing the creation of pike modules and applications. Thanks again! Bill -- H. William Welliver / Fairchild Semiconductor Mountain Top Systems email: bill.welliver(a)fairchildsemi.com / phone: 570.474.6761 x4445 cell: 570.262.7151

Defines and dumped modules
by Johan Sundstr�m, Lysator ＠ Pike developers forum 23 Oct '03

23 Oct '03

Are #ifdefs and similar define-dependent code intentionally stripped for dumped modules? I just recompiled a fresh 7.5 and noticed that I could not use -DHTTP_QUERY_DEBUG until I removed all .o files. :-7

Pike-Doc WiKi
by fomyers＠netwalk.com 21 Oct '03

21 Oct '03

I've been trying to learn Pike. Since I already program in C++, XBasic, and other OOP languages, I have noticed that the same roadblock pops up over and over again when I am working in Pike. I keep having to review the pmod "implementation" files to find clarification for parameters, usage of methods, and class inheritance relationships. I think that this is because the reference manual seems to be a bit thin in a few places. As a way to encourage more input to the documentation, Could we use the existing Wiki as a Documentation repository? That way, as Pike Programmers "discovered" information about modules, classes, and methods, we could save the information, or examples of use in the WiKi... Thanks for your time, I hope this helps. Sincerely, Frank Myers

That should read "garbage collection", not "protection".
