Process.run
by Peter Bortas (nu med mindre Opera) ＠ Pike (-) developers forum 14 Jul '08

14 Jul '08

I just checked in a Process.run() in 7.7: http://pike.ida.liu.se/development/cvs/diff.xml?module=Pike&file=7.7/lib/mo… The rational for that is that I was once again reminded by a user this week that getting Process.create_process() or Process.Process right without some corner case blocking is hard. It's not obvious that if you bind pipes to booth stderr and stdout you have to take in to account that OS buffers are not limetless. Process.run() is a thin wrapper around Process.Process that collects stdout, stderr and exitcode and return them in a mapping. This could potentially result in huge strings, but will do what most users want and even already do when they call create_process() with both pipes bound. Something like this should be in 7.8, but I'm open to suggestions for other things that might be usefull to return in the mapping or for changing member names.

Subversion repository
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 05 Nov '06

05 Nov '06

I now have a rather complete conversion of the Pike repository to Subversion (some more copyfrom links could be added, but otherwise everything should be ok). It includes all checkins up to and including 2006-08-29, which when I'm writing this means "everything". The dump file is in pelix:/pike/home/marcus/pike_svn.dump.gz. My suggestion is that we create an accessible repository from this somewhere, to be able to work on tooling, and to check for glitches in the conversion. Once that is ready, I'll make a new conversion for the actual switch. Which means that everything checked into the temporary repository would be discarded. I have not converted projects/ or Pike/ulpc or Pike/extra_tests, as these are not branches of the main Pike development tree. Any opinions on whether to convert some or all of these, and in that case should they be in the same repository or a different one? Some statistics: Conversion: ----------- Number of revisions: 31738 Conversion script run rime: 15h 15mins (on pelix) Dump size (uncompressed): 1.7Gb Dump size (compressed): 384Mb Test import: ------------ Dump import time: 4h 24mins (on bhelliom) Reposiory size: 421Mb (with fsfs)

pre 7.2 lib/modules/SSL.pmod ,v files
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 03 Nov '06

03 Nov '06

In trying to convert the Pike CVS repositories to Subversion, I've come across something really odd. Looking at the ,v files in /pike/data/cvsroot/Pike/7.2/lib/modules/SSL.pmod, it seems that this module was created on 1997-03-13, and included in such tags as "pike_v0_5_release_47". Yet, there is no trace of this module under /pike/data/cvsroot/Pike/0.5 (or 0.6, or 7.0), under this name or any other as far as I can tell. Where are the missing ,v files? Did somebody miss some CVSROOT/modules magic when copying the repositories from RIS?

c modules and function names
by H. William Welliver III 13 Oct '06

13 Oct '06

what is the best way to determine the name of the function being run when in a c module? I'm using name = ID_FROM_INT(Pike_fp->current_object->prog, Pike_fp- >fun)->name; when calling non-constant functions, but that doesn't seem to work when the function being called was added using add_function_constant(). any suggestions?

File references
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 10 Oct '06

10 Oct '06

We have problem with the internal circular references within the Stdio.File objects. The problem is that not only are the objects as garbage until gc, but the associated file descriptors as well. This becomes a problem with massive amounts of connections. Our short term solution is to sprinkle the code with destruct(file->fd), but I would like to ask what can be done within Pike, both short term (if anything) and as long term solution.

dynamically generated programs
by Bill Welliver 26 Sep '06

26 Sep '06

I'm working on some code that generates c level programs dynamically, and was wondering if there's any way to include some data in the program definition. Right now, I'm adding a string constant that contains some text, and when an object is created from the class, I fill in the c level structures. That works, but it seems somewhat less efficient than if I were able to specify some data for the program. I looked at the definition for struct program, and didn't see anything obvious, but figured I'd ask the experts :) For those interested in the rationale, I'm working on adding inheritability to my objective c module. I've got a method that will generate a pike program for an objective c class, inspecting the class and creating stubs for each method in that class. Right now, I don't see any way to include a pointer to the class in the program definition, so I'm currently adding a constant that contains the class name. Then, when the object is instantiated, I look up the constant and then look up the class from the value of the constant. I'd like to cut down on the overhead of this operation, if possible. Thoughts?

A hefty cleanse
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 14 Sep '06

14 Sep '06

So Ssleay, Pipe, Perl and Mird are gone from 7.7. Was decided upon through a very enlightened consensus, I'm sure. Could we outsiders get a rundown on the rationale behind this too? Don't they work at all? Commit messages talk about removing from "standard Pike". Are they going to appear somewhere else?

Re: threading and externally created threads
by H. William Welliver III 13 Sep '06

13 Sep '06

I finally had some time to look at this, and native_dispatch() had exactly what I was looking for. However, I found a problem (at least for me) in THREADS_ALLOW(): when you call this macro, it checks if threads are enabled and the number of threads. If there are more than one thread, it unlocks the interpreter. The problem is, if you only have one thread when you call THREADS_ALLOW(), the lock doesn't get released and any code running in "temporary pike external" threads will just sit there. I imagine that this is only a problem for things like the java bridge and my code, but thought I'd mention it in case there's a simple solution. I have taken to starting a thread that simply enters a sleep () loop before creating my external threads, and this works just fine. Anyone have a better solution?

developers at conference?
by H. William Welliver III 11 Sep '06

11 Sep '06

Will any of you guys be at the conference? I've got some questions about some ideas I have for the objective c bridge i've been working on, and figured it would be easier to have a conversation about it than try to do it via email.
