[pacman-dev] Install files and messages
by Dan McGee 10 Jan '07

10 Jan '07

I don't know what other peoples thoughts are, but I think the current install file system and scriptlets...seems like a drop in at some point that wasn't fully done right. Most packages currently use the file for one of two purposes that I can see: 1. display informational messages 2. perform operations that can't be done in the build phase. The install scriptlets were likely originally meant more for number 2, but has become more and more about providing number 1. Here are some relevant bugs and postings: metadata messages in PKGBUILD <http://bugs.archlinux.org/task/1571> display all post-install messages at once <http://bugs.archlinux.org/task/6143> global on-install system <http://bbs.archlinux.org/viewtopic.php?p=219152#219152> Here are my thoughts on the situation. As every package builder seems to have their own presentation format for displaying messages (e.g. echo ">>>...", echo " **...**"), it would be nice to have a way to unify it. Most (all?) messages are in one of two places- post_install or post_upgrade. I propose these messages should be moved out of these scriptlets, and moved into a variable, likely still located in the install file as this is packaged up with the package (unlike the PKGBUILD). These variables could be called install_msg and upgrade_msg, respectively. The scriptlets would still remain, but any output would be 'nonessential'. By changing where the messages stem from, it would make it easier for bug 6143 to be fixed, and would also make for cleaner output to pacman.log, now that all messages are being logged there. Finally, _alpm_runscriptlet seems pretty complicated...I'm wondering if it couldn't be cleaned up a bit by someone that is better with forks and popens. There is also some duplicate code. -Dan

This is my massacre of _alpm_load_pkg in package.c (just joking about the massacre). I moved the extremely large for loop into its own function (and made it a while loop). Feel free to change the name of _alpm_pkg_checker (first thing that came to mind). The patches for package.c and package.h are below. ~ Jamie / yankees26

[pacman-dev] My $0.02 on the Frugalware v.s. Arch bit...
by Scott Horowitz 02 Jan '07

02 Jan '07

I hate to wade into this, but let me just say... there's no doubt in my mind that this will never be resolved while the (inflammatory) sentiment in the pacman-g2 README exists. For starters, the whole point being made about the API not being stable, which seems to be points 1 and 2 in the README, are plain silly. No project should take a project's cvs development code and expect the API to remain stable; Frugalware knew what it was getting into when it grabbed this code to put into their repositories. There's a reason that pacman3 hasn't been released yet on Archlinux, and that there haven't been Archlinux frontends developed. Pacman3 development shouldn't be hindered because someone decided to release the code into the wild, and it's clearly going under some large refactoring. As for point 3, Aaron's supposed disinterest in contributor's patches - I think it has been quite clear from the mailing list that this isn't the case. The real justification behind this sentiment, which was brought up in the original email and I agree needs improvement, is that there could use more openness (such as in response to a WONTFIX patch) between all the parties. Then there's the stuff about how development has fallen behind schedule (what project hasn't?) and Aaron asked Frugalware to fork things (I'm pretty sure this was more tongue-in-cheeck about how Frugalware is doing things than anything). These seem pretty petty to me. In my opinion, two things need to happen, one from each side. On the Archlinux side, I think Aaron should make a better attempt to be more transparent in his responses, which would hopefully encourage debate. On the Frugalware side, I think the whining about API stability needs to be dropped and, rather than take the "fork" talk as a challenge, they should be asking what needs to be done to make the two paths more compatible. Happy Holidays, Scott

[pacman-dev] pacman-optimize updates
by James Rosten 31 Dec '06

31 Dec '06

I came up with a patch for FS #5009 (the error when /var/lib/pacman is a loopback device or other mounted partition. I have not been able to test it yet, as I am on my mac (so sending this with Mail, so let us hope it doesn't mess this up :P), but in a few hours I'll be on my Arch computer and I'll test it then and obviously report back. Also, fixed the step number in the comments ('cause I am that nit pickish), because there were two step 1's. ~ Jamie / yankees26

I've refactored _alpm_checkconflicts, but there appears to be something slightly off. With a normal cvs build of pacman3, trying to install sonata-svn with normal sonata produces this: loading package data... done.checking dependencies... :: sonata-svn conflicts with sonata. Remove sonata? [Y/n] y error: failed to prepare transaction (conflicting dependencies) :: sonata-svn: conflicts with sonata But with my patch: loading package data... done.checking dependencies... done. checking for file conflicts (1/1) [###############################################################] 100% error: failed to prepare transaction (conflicting files) sonata-svn: /usr/bin/sonata exists in filesystemsonata-svn: /usr/lib/python2.4/site-packages/mmkeys.so exists in filesystemsonata-svn: /usr/lib/python2.4/site-packages/mpdclient3.py exists in filesystemsonata-svn: /usr/lib/python2.4/site-packages/mpdclient3.pyc exists in filesystemsonata-svn: /usr/lib/python2.4/site-packages/sonata.py exists in filesystemsonata-svn: /usr/lib/python2.4/site-packages/sonata.pyc exists in filesystemsonata-svn: /usr/share/applications/sonata.desktop exists in filesystemsonata-svn: /usr/share/locale/de/LC_MESSAGES/sonata.mo exists in filesystemsonata-svn: /usr/share/locale/fr/LC_MESSAGES/sonata.mo exists in filesystemsonata-svn: /usr/share/locale/pl/LC_MESSAGES/sonata.mo exists in filesystemsonata-svn: /usr/share/locale/ru/LC_MESSAGES/sonata.mo exists in filesystemsonata-svn: /usr/share/pixmaps/sonata.png exists in filesystemsonata-svn: /usr/share/pixmaps/sonatacd.png exists in filesystemsonata-svn: /usr/share/pixmaps/sonatacd_large.png exists in filesystemsonata-svn: /usr/share/sonata/CHANGELOG exists in filesystemsonata-svn: /usr/share/sonata/README exists in filesystemsonata-svn: /usr/share/sonata/TODO exists in filesystemsonata-svn: /usr/share/sonata/TRANSLATORS exists in filesystem errors occurred, no packages were upgraded. As you can see it flipped out, but even with the normal pacman3 it still fails to install. Both were executed with: sudo ./pacman.static -A /var/abs/local/sonata-svn/sonata-svn-246-1.pkg.tar.gz Using -U instead of -A yields the same results. So below is the patch for you guys to look over and see what might be screwing this up (cause I have no idea). ~ Jamie / yankees26

After trying to build pacman3 so I could test something for stonecrest, I found some errors in my patch and Dan's (very small, you forgot to put the label error before return(-1);) while compiling. So below is the better patch than the other patch (which should be ignored). It patches package.c, package.h, and sync.c of libalpm. ~ Jamie / yankees26

Some more functions that are worth taking a look at on the libalpm side: add.c: _alpm_add_commit be_files.c: _alpm_db_read _alpm_db_write conflict.c: _alpm_checkconflicts _alpm_db_find_conflicts package.c: _alpm_pkg_load (getting a bit long) remove.c: _alpm_remove_commit server.c: _alpm_downloadfiles_forreal sync.c: _alpm_sync_sysupgrade (getting there) _alpm_sync_prepare _alpm_sync_commit And some minor things I found in the code- cleaned up an extern enum, changed 'md5' variable to 'hash' as it can be either md5 or sha1, resorted db.h for clarity, and fixed some English grammar issues.

[pacman-dev] New mirrors file
by Dan McGee 28 Dec '06

28 Dec '06

Saw this (http://bugs.archlinux.org/task/6083) bug today on the bugtracker and also knew this was a problem anyway, so here is my go at it. I tried to make a more up to date mirror list from both the Wiki and the download page. I ran the rankmirrors script on it a few times to hopefully weed out the old/bad mirrors. If someone that is skilled with automake/autoconf wants to finish the job, I'd appreciate it. Instead of having four more or less duplicate files in our repository, we could generate all of them from this one file. -Dan /etc/pacman.d/mirrorlist.in: # # @REPO@: Arch Linux @REPO@ repository # # United States Server = ftp://ftp.archlinux.org/@REPO@/os/@CARCH@ Server = ftp://ftp.nethat.com/pub/linux/archlinux/@REPO@/os/@CARCH@ Server = ftp://ftp-linux.cc.gatech.edu/pub/linux/distributions/archlinux/@REPO@/os/@… Server = ftp://mirror.cs.vt.edu/pub/ArchLinux/@REPO@/os/@CARCH@ Server = ftp://ftp.ibiblio.org/pub/linux/distributions/archlinux/@REPO@/os/@CARCH@ Server = http://www2.cddc.vt.edu/linux/distributions/archlinux/@REPO@/os/@CARCH@ # Europe # - Austria Server = ftp://gd.tuwien.ac.at/opsys/linux/archlinux/@REPO@/os/@CARCH@ # - Belgium Server = ftp://ftp.belnet.be/packages/archlinux/@REPO@/os/@CARCH@ # - Czech Republic Server = ftp://ftp.sh.cvut.cz/MIRRORS/arch/@REPO@/os/@CARCH@ # - Estonia Server = ftp://ftp.estpak.ee/pub/archlinux/@REPO@/os/@CARCH@ # - France Server = ftp://ftp.rez-gif.supelec.fr/pub/Linux/distrib/archlinux/@REPO@/os/@CARCH@ Server = ftp://mir1.archlinuxfr.org/archlinux/@REPO@/os/@CARCH@ Server = ftp://mir2.archlinuxfr.org/archlinux/@REPO@/os/@CARCH@ Server = ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/archlinux/@REPO@/os/@CARCH@ #Server = http://mirrors.jakimowicz.com/archlinux/@REPO@/os/@CARCH@ # - Germany #Server = ftp://ftp.archlinux.de/pub/archlinux/@REPO@/os/@CARCH@ Server = ftp://ftp.tu-chemnitz.de/pub/linux/sunsite.unc-mirror/distributions/archlinux/@REPO@/os/@CARCH@ Server = ftp://ftp.hosteurope.de/mirror/ftp.archlinux.org/@REPO@/os/@CARCH@ # - Great Britain Server = http://ftp.parrswood.manchester.sch.uk/Mirrors/ftp.archlinux.org/@REPO@/os/… # - Greece Server = ftp://ftp.ntua.gr/pub/linux/archlinux/@REPO@/os/@CARCH@ # - Ireland Server = ftp://ftp.heanet.ie/mirrors/ftp.archlinux.org/@REPO@/os/@CARCH@ # - Italy Server = ftp://mi.mirror.garr.it/mirrors/archlinux/@REPO@/os/@CARCH@ # - Lithuania Server = ftp://saule.mintis.lt/pub/linux/@REPO@/os/@CARCH@ # - Netherlands Server = ftp://ftp.nluug.nl/pub/metalab/distributions/archlinux/@REPO@/os/@CARCH@ Server = ftp://ftp.surfnet.nl/pub/os/Linux/distr/archlinux/@REPO@/os/@CARCH@ # - Norway Server = ftp://mirror.djzradio.net/archlinux/@REPO@/os/@CARCH@ # - Poland Server = ftp://sunsite.icm.edu.pl/site/linux-sunsite/distributions/archlinux/@REPO@/os/@CARCH@ Server = ftp://mirror.icis.pcz.pl/archlinux/@REPO@/os/@CARCH@ # - Portugal Server = ftp://gul.est.ips.pt/repos/archlinux/@REPO@/os/@CARCH@ Server = ftp://cesium.di.uminho.pt/pub/archlinux/@REPO@/os/@CARCH@ Server = ftp://darkstar.ist.utl.pt/pub/archlinux/@REPO@/os/@CARCH@ # - Romania Server = ftp://ftp.iasi.roedu.net/mirrors/archlinux.org/@REPO@/os/@CARCH@ # - Sweden Server = ftp://ftp.ds.hj.se/pub/os/linux/archlinux/@REPO@/os/@CARCH@ Server = ftp://ftp.gigabit.nu/@REPO@/os/@CARCH@ # - Switzerland Server = ftp://archlinux.puzzle.ch/@REPO@/os/@CARCH@ # Australia Server = ftp://mirror.pacific.net.au/linux/archlinux/@REPO@/os/@CARCH@ # Asia # - China Server = http://mirror.vxmatrix.net/ArchLinux/@REPO@/os/@CARCH@ Server = http://dxmirror.vxmatrix.net/ArchLinux/@REPO@/os/@CARCH@ Server = http://cncmirror.vxmatrix.net/ArchLinux/@REPO@/os/@CARCH@
