Re: Playing music using pike and SDL.
by Martin Nilsson (lvl 60) ＠ Pike (-) developers forum 03 Dec '25

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

Process.run
by Peter Bortas (nu med mindre Opera) ＠ Pike (-) developers forum 15 Jul '08

15 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 06 Nov '06

06 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 04 Nov '06

04 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?

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?

Image.Image()->scale(x) int or float?
by Martin Bähr 28 Aug '06

28 Aug '06

hi, i noticed a minor difference between the documentation and the implementation of Image.Image()->scale(); according to the documentation, if scale() is given only one argument, it must be a float. in reality it accepts an int as well as a float. this is significant in the sense that one could assume that scale(5) is equivalent to scale(5, 0) because that is usually the case when the second argument is optional, whereas in this case it actually is equivalent to scale(5.0) i prefer to assume that the documentation is wrong, but i would like to know if that assumption is correct. greetings, martin.

Variable expansion in makefiles
by Marcus Agehall (PacketFront) ＠ Pike (-) developers forum 26 Aug '06

26 Aug '06

I'm trying to install new modules using monger but it's not working as I would expect. It seems to download and configure just fine, but the makefiles are broken. It seems the @propagated_variables@ keyword is never expanded and I can't figure out why. I've tried using both pike 7.6.26 and 7.7 from CVS. Currently I'm using autoconf 2.13 but I also tried with 2.50 with the same results. Anyone else experiencing the same thing or know what the problem is?

It is time for a new release of Pike 7.6. Is there anyone who can do the release notes? If not, we'll just wait a bit longer...

[Martin Pitt: Question about PostgreSQL SQL injection fix in 7.6.86]
by Martin Bähr 17 Aug '06

17 Aug '06

forwarding this to the developers forum in case some of you don't read the pike user list as closely... ----- Forwarded message from Martin Pitt <martin.pitt(a)ubuntu.com> ----- Date: Thu, 17 Aug 2006 09:40:53 +0200 (MEST) Hi Pike developers, The 7.6.86 announcement advertises a "Fix for potential SQL injection vulnerability in Postgres." Mitre assigned CVE-2006-4041 to this, but there is very little information about the vulnerability. I found this in CVS: ---------------------------- /cvs/Pike/7.6/lib/modules/Sql.pmod/Sql.pike revision 1.26 date: 2006/06/06 03:25:59; author: adam; state: Exp; lines: +4 -2 Make Sql.postgres objects use the safe quote() method if available. ---------------------------- /cvs/Pike/7.6/src/modules/Postgres/ revision 1.25 date: 2006/05/24 17:49:56; author: adam; state: Exp; lines: +5 -2 backport SQL injection fix from 7.7 revision 1.40 date: 2006/05/24 17:49:56; author: adam; state: Exp; lines: +39 -2 backport SQL injection fix from 7.7 ---------------------------- which seems to be the fix for the recent general PostgreSQL/MySQL \' -> '' quote escaping issue (CVE-2006-2314 for PostgreSQL). Does that announcement refer to this quoting fix (it would match the description)? Thank you, Martin -- Martin Pitt http://www.piware.de Ubuntu Developer http://www.ubuntu.com Debian Developer http://www.debian.org In a world without walls and fences, who needs Windows and Gates? ----- End forwarded message -----
