[pacman-dev] Status of _alpm_find_first_satisfier?
by Nagy Gabor 02 Jul '08

02 Jul '08

Hi! I would like to ask you about this patch: http://shining.toofishes.net/gitweb/gitweb.cgi?p=pacman.git;a=commit;h=aae0… * I'd like to refactor resolvedeps, and this function would be useful there. (I think *list param can be input/output list of resolvedeps like in recursedeps (and kill syncpkg param), and "find_literal" "find_othersatisfier" parts can be moved to its own function and used by front-end too...) * Xavier says that this patch "Address two concerns". One of them is the memleak caused by current _alpm_find_dep_satisfiers usage (which returns with a list, but we don't free it), which needs to be fixed even if this patch will be rejected. I think that _alpm_find_first_satisfier implementation is a bit complicated... I would prefer just ~reimplement _alpm_find_dep_satisfiers instead of calling it (and introducing a new "wrapper"). Bye

[pacman-dev] repo-add error in BSD
by Antonio Huete Jimenez 01 Jul '08

01 Jul '08

repo-add uses readlink -f in linux to find out file's real path. readlink is part of coreutils. I've found that readlink in BSD don't support -f option so we need to use realpath instead. Attached you can find a mini-patch. Cheers, Antonio Huete

[pacman-dev] Alternative to autotools: waf?
by Sebastian Nowicki 30 Jun '08

30 Jun '08

Hi, I have been looking for a nice build system, for personal, for quite some time now. I saw waf at one point and thought it might be a good system, but I never paid much attention to it. Recently I again started looking into it and I decided to use pacman to test out how good it is. In comparison to autotools, the language (python) is a lot simpler and easier to understand, although it still took a while to understand waf. The size of the configuration script is significantly smaller (see statistics below). The waf website also claims that it is faster than autotools, I believe it is, but I did not actually benchmark anything. So far I've managed to get libalpm to compile (shared library only), and pacman shouldn't be too hard since most of the stuff is already there. The script is far from being finished, I simply wanted to see how difficult it was to get something compiled, while linking against external libraries. I just wanted to see if anyone was interested in actually using waf as the build system for pacman. If not, I'm not sure that I'll be bothering with compiling pacman, since I only really need libalpm. Not sure if all these files are created by people, but even configure.ac alone is larger; > $ wc -l configure.ac Makefile.am config.* acinclude.m4 > 404 configure.ac > 29 Makefile.am > 1526 config.guess > 614 config.rpath > 1658 config.sub > 4952 acinclude.m4 > 9183 total > > $ wc -l wscript > 143 wscript Note: The build script has only been tested on Mac OS X, and thus I don't know if it links properly against libdownload.

[pacman-dev] pac-file utility script
by pete morris 29 Jun '08

29 Jun '08

Hi all, First a quick introduction, since this is my first message to the list. I am a CS grad student at James Madison University in Harrisonburg, VA, and I also do IT work for JMU's art department. I've been using arch for around 2.5 years now. Anyway, I've written a script that takes advantage of the [repo].files.tar.gz filelists that are now available to discover which package provides a particular file, when that package is not installed on the user's machine. It is similar to debian's apt-file, if you are familiar with that. I would appreciate any comments on the script, with an eye toward possible inclusion in Allan's pacman-contrib community package. The script uses the mirrors defined in the user's /etc/pacman.d/mirrorlist and downloads the filelists for the repos enabled in /etc/pacman.conf. It is available from http://threadstates.com/downloads/pac-file. The only major issue I can see is in the handling of non-standard repos, including local ones. The repo names are obtained from pacman.conf's "[repo]" lines, and the name of the repo is substituted for $repo in the mirror url from the mirrorlist. If a local repo (for example) is defined in pacman.conf as "[local]", on a 'sync' operation, pac-file will attempt to download local.files.tar.gz from every mirror enabled in the mirrorlist. This will not cause the script to fail (it will report that the file is unavailable from any mirror and continue on), but it will waste time. I am hesitant to limit the possible repos to the official ones because there might be third party repos that provides filelists. Suggestions? Thanks, Pete
