This is a nice patch! As I see (I couldn't test it), your test doesn't produce the same result as mine: change self.args to "-Se pkg1 pkg2" in my sync1002.py.

[pacman-dev] Maelstrom(Pacman in C#) project brief
by Bozhidar Batsov 23 Jul '07

23 Jul '07

My implementation of pacman's functionality codenamed "Maelstrom" has reach a usable state. I actually managed to graduate thanks to it, as it was my graduation task, so now I'm an engineer from the Technical University of Sofia, Bulgaria. Currently my project supports most of pacman's capabilities + a few more, but I was thinking what is the community's opinion on the subject - is there any point in developing another pacman... I'd like to hear from you, because I was thinking to do a complete overhaul of Maelstrom to make it more sturdy and elegant and to release it to the general public, but maybe that will be pointless if no one thinks there is the need of another implementation of the package management system. Here are some finer points of the maelstrom project: 1. This is not a client for libaplm - it is a complete framework written from scratch without even consulting the original source code. It consists of a couple of libraries and two clients - one console app and one written in GTK#. Everything is 100% percent coded in C# 2.0. 2. Instead of the current db format - files hierarchy located under /var/lib/pacman, maelstrom relies of a RDBMS for it's bookkeeping, though it creates the entries in pacman's DB as well for backwards compatibility. 3. I can initially import in it's DB the current state of pacman's DB. 4, It understands the format of pacman.conf and parses it natively. Here are a couple of screenshots: ftp://78.128.17.199/sync.png ftp://78.128.17.199/refresh.png ftp://78.128.17.199/whirl.png

[pacman-dev] Pacman doesn't handle properly the multiple satisfiers, localdb corruption
by ngaba＠petra.hos.u-szeged.hu 21 Jul '07

21 Jul '07

Hi! Well, you probably will ask me to send patch, but I'm waiting for your decision. First, here is the problem: ===requiredby005.py== self.description = "Remove lp1, requiredby should move from lp1 to lp2" lp1 = pmpkg("foo") lp1.requiredby = ["pkg3"] self.addpkg2db("local", lp1) lp2 = pmpkg("pkg2") lp2.provides = ["foo"] self.addpkg2db("local", lp2) lp3 = pmpkg("pkg3") lp3.depends = ["foo"] self.addpkg2db("local", lp3) self.args = "-R %s" % lp1.name self.addrule("PACMAN_RETCODE=0") self.addrule("!PKG_EXIST=foo") self.addrule("PKG_EXIST=pkg2") self.addrule("PKG_REQUIREDBY=pkg2|pkg3") ------------------------- This test fails and hence the database becomes corrupt: alpm_checkdeps is clever enough to let pacman remove foo, however update of pkg2's requiredby is missing after the remove. However, this is not a pactest to commit: as you see, pkg2's requiredby field is missing: this can happen, if pkg3 was the last installed package, because _alpm_trans_update_depends works in a "funny" way: it fills in the "literal" satisfier's requiredby only or _all_ "provider" satisfiers' requiredby. So, my question, how I fix this? How should we store multiple satisfiers in localdb? case 1: We find all satisfier package and fill in _all_ requiredby fields. case 2: We flag only one package as a satisfier with requiredby, and we handle properly these requiredby "moves". case 3: any other idea? We must choose one, because this is not defined in pacman now. I prefer case 1. Pros: -easy to implement (only _alpm_trans_update_depends needs patching) -by doing this, we clean up _alpm_trans_update_depends using alpm_depcmp -_alpm_pkg_update_requiredby prefers this way now -this won't break prepare/commit hierarchy (because alpm_checkdeps should somehow inform remove_commit in case 2) -when using -d switch, implement case 2 is difficult Contras: -slower!! (we need to check for providers always) -some users may have corrupted(?) localdb as shown in the pactest file (this is rare) -one satisfier is enough Bye, ngaba ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[pacman-dev] alpm_list_* functions : public or private ?
by Xavier 19 Jul '07

19 Jul '07

The functions in alpm_list.c all start with alpm_list_, but some of them don't have SYMEXPORT. By reading the rest of the code, I assumed that : _alpm_* == private alpm_* == public (so with SYMEXPORT) Is this a real rule ? If so, should all functions in alpm_list.c be symexported, or should the ones without SYMEXPORT be renamed to _alpm_* ?

[pacman-dev] feature request: create .tar.gz package from an installed one
by ngaba＠petra.hos.u-szeged.hu 18 Jul '07

18 Jul '07

Hi! In my opinion one of the best thinks in pacman that unlike many other package managers user can undo lots of thinks (see -R group after -S group, -Rs after -S ...). However, user cannot undo a package upgrade, because most sync servers doesn't store old packages. So I think that it would be very useful, if there would be a pacman or makepkg command to create a package from an installed one (or is this implemented?). We could(?) do this from the local db and the installed files. Of course this wouldn't be a "distro" package, because config files can change etc. but this is even better for backup/undo. You may say, that this is totally useless, because if a package is installed then there must exist a proper .tar.gz file somewhere. -but package can be installed from aur and user may deleted the "binary" file -if you move to a place with no network, you can easily create "backup" packages before -R (and reinstall) or you can give this package to your Archer friend -slightly reduces needless Arch-server using -it can be easily implemented (IMHO) Bye, ngaba ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

> Oh yes, please, clean that update_depends function, trying to read it almost > killed me. (so go with case 1 I guess). OK, but one more question: tranc.c:461: if(trans->packages && trans->type == PM_TRANS_TYPE_REMOVE) { if(_alpm_pkg_find(dep->name, handle->trans->packages)) { continue; } } Should I keep this or remove? I prefer remove, but I'm not sure. Pro (for keeping): this reduces the slow disk write in many cases (usually there is dependency between the removed packages) Contra: this breaks libalpm hierarchy, it assumes that the remove_commit will be successful; if not, or user break or... then the database can become corrupted (however, extra requiredby is not a big trouble, as you said), so this is a bit unsafe.

[pacman-dev] File/Path locations
by Andrew Fyfe 17 Jul '07

17 Jul '07

At the moment the file/path locations and where/how they are set is a bit of a mess, here's the idea I propose... Default locations set by configure: Root Dir : / DB Path : $localstatedir/lib/pacman Cache Dir : $localstatedir/cache/pacman/pkg Lock File : $localstatedir/run/pacman.lck Cfg File : $sysconfigdir/pacman.conf Pkg Ext : .pkg.tar.gz DB Ext : .db.tar.gz Source Ext: .src.tar.gz Where locations are set/overridden: Hard Code into pacman/scripts: - Cfg File Set in pacman.conf: - DB Path - Cache Dir - Lock File - {Pkg,DB,Source} Ext Override on cmd line: - Root Dir - DB Path - Cache Dir - Cfg File Default behaviour for 'pacman --root' pacman --root /foobar Root Dir : /foobar DB Path : /foobar/$localstatedir/lib/pacman Cache Dir : /foobar/$localstatedir/cache/pacman/pkg Lock File : /foobar/$localstatedir/run/pacman.lck Cfg File : /foobar/$sysconfigdir/pacman.conf Also to make the paths/locations available to scripts we could use iniread[1] written by James Rayner eg --- pacman.conf [options] dbpath = /var/lib/pacman --- makepkg.conf DBPATH=$(iniread /etc/pacman.conf options:dbpath) Thoughts, comments and ideas welcome.
