[pacman-dev] sync_prepare clean-up III, TODO
by Nagy Gabor 30 Jul '07

30 Jul '07

Hi! Well, the remaining part is very messy and disappointing: The whole conflict checking should be refactored: as I assume this wants to do something similar to checkdeps(...TRANS_TYPE_UPDATE), but that is buggy: this should be fixed as deps.c (conflict001.py shows this.) However, as Xavier said earlier a new data stucture is needed for conflicts; and all conflict resolve stuff should be moved to conflict.c. The second pactest file shows checkdeps cannot get enough information from sync.c to figure out if there is any broken dependency: it should know BOTH the remove and upgrade list to decide properly. Well, both of this bugs needs hard work: a proper conflict resolution is a difficult (probably recursive) problem, it would be easier to let user do this work manually. Bye, ngaba PS: I don't like inefficient pmsyncpkg_t neither.

[pacman-dev] pacman_deptest function
by Xavier 28 Jul '07

28 Jul '07

I've benn looking at that function again, and here is what I saw in Andrew's commit : +/* TODO: This should use _alpm_checkdeps() */ int pacman_deptest(alpm_list_t *targets) As I tried to explain there : http://www.archlinux.org/pipermail/pacman-dev/2007-June/008654.html checkdeps isn't really what we want. Here, we just want to check that a list of dependencies from the PKGBUILD is already installed locally. checkdeps however checks if we can install a package, by checking its dependencies. And checkdeps gets this information from the sync or local databases, it can't really get the deps list from an external PKGBUILD. But there is at least one way to do that, it's creating a dummy package, with the same list of dependencies as in the PKGBUILD, and work with that in libalpm. I looked at the history of deptest(), and it's actually what Aurelien did at some point : http://projects.archlinux.org/git/?p=pacman.git;a=commit;h=0756af675d6b99a1… http://projects.archlinux.org/git/?p=pacman.git;a=commit;h=cda9c6671ced31a7… But it was rather messy, so Aaron cleaned that : http://projects.archlinux.org/git/?p=pacman.git;a=commit;h=4dd6c9222879198e… So well, I still have the same opinion that in my earlier answer to Andrew, what pacman_deptest does is just the mythic "search for satisfier" function that Nagy has been talked about for ages, and that is used everywhere in the code :)

[pacman-dev] Pointless public/private functions
by Andrew Fyfe 27 Jul '07

27 Jul '07

Throughout the libalpm and pacman code there's a lot of public functions that simply wrap a private function (maybe with some asserts). What's the point? Why not have the asserts in the private function and make the private function public reducing the number of function being called? Andrew

[pacman-dev] Parsing config file question
by Andrew Fyfe 27 Jul '07

27 Jul '07

Why does pacman do this... if(strcmp(key, "ShowSize") == 0 || strcmp(upperkey, "SHOWSIZE") == 0) Is there any reason why we can't do... if(strcmp(upperkey, "SHOWSIZE") == 0) Andrew PS Just found the ILoveCandy option :D

[pacman-dev] [patch] sync_prepare clean-up I: 2in1 -Se bugfix (fwd)
by Nagy Gabor 24 Jul '07

24 Jul '07

Hi! The pactest shows 2 bugs: Pacman should add pkg3 to the transaction, because pkg2 depends on pkg3 (bug1), but at least checkdeps should show that a dependency is missing (bug2): here a wrong variable (list) is passed to checkdeps. The patch is designed for bugfix for bug1, but also fixes bug2. Bye, ngaba

>That pactest doesn't look right, does it? Oh, yes; copy/paste (fix sync / local):-P I'm on holiday now, there is no linux machine here, but you can probably fix the pactest file; after reading the code: the corrected pactest file probably fails. Bye, ngaba

You are right, but since this is a rarely used function, IMHO speed is not so important here (in my opinion: this function should be as simple as possible). Bye, ngaba
