[pacman-dev] Doing more stuff with optdepends
by Allan McRae 25 Mar '09

25 Mar '09

Hi, I have been thinking about optdepends and if we can improve the handling of them. So, given I am better at making wiki pages than patches... http://wiki.archlinux.org/index.php/User:Allan/Pacman_OptDepends What do people think about this idea? Are there other sensible additions to that proposal? I know that optdepends were originally for getting rid of informational messages but I have some packages on my system that are installed "explicitly" when they are really (opt)deps for other packages.

[pacman-dev] patch submission help
by Jeff 18 Mar '09

18 Mar '09

In the last month I have created and tested [1] a patch for pacman-3.2.2 that allows for 3 different PKGBUILD functions: build() check() inst(). This allows for a new option in makepkg.conf called check which is expected to default to !check (and overridden for toolchain packages). build() and check() are never run in fakeroot, only inst() (with exception for !fakeroot or --asroot, of course) which conforms to the fakeroot recommendation. My attempt was to make the patch backwards compatible so that if any of the functions weren't present, it was not an error. However, I realized while writing this email that this means that a PKGBUILD with just build() would run completely in a non-fakeroot environment which needs re-thinking. Anyway, it's a rather small patch as seen below: $ grep ^- makepkg.patch | grep -v ^--- |wc -l 16 $ grep ^+ makepkg.patch | grep -v ^+++ |wc -l 33 The reason for this email, though, is that I subbed to this list to watch how things are done, learn protocol, etc. So I grabbed the git repo and started looking at how I was going to apply this patch since enough has changed to cause all but 1 hunk to fail. I am not familiar with git, preferring svn, but can read docs. Where I'm tripped up is realizing that head doesn't reflect what private branches might hold. One person (sorry, I forget who) mentioned having a branch with many makepkg changes in it which would cause me to have to hand apply these changes again. I have no interest in doing that, so I'm asking: does this feature seem like it would be worthwhile (read; would the patch be accepted)? If so, how do I access private branches so my branch doesn't conflict with them? [1] I am building a base system with the new PKGBUILD format and am about 3/4 of the way done with no known makepkg errors (running makepkg with sh -x for extra detail) -- Jeff My other computer is an abacus.

Obviously the toolchain would be in that category whereas some would argue things like sed's testsuite is minor and generally not worth the time or trouble to run. Personally this wouldn't affect me as I run every testsuite. -- Jeff My other computer is an abacus.

This can be dangerous, unless the pacman devs personally undertake the migration of all extant PKGBUILDs. Since I just realized the problem yesterday, I have not had time to think about the best fix, but I think the fix should be rather trivial at least in reference to my patch. I'd really like to see your branch and I could send you my patch (onlist/offlist your choice) as a matter of reference if you would like my input. > I like the idea of an additional check() function. However, I could > implement it slightly differently - instead of a makepkg.conf flag to > run the check() function or not, I think it may be better to add a > --check flag to makepkg so people specify when to run it. >From a technical standpoint, I prefer the --check arg better than putting an option override in a PKGBUILD, but then I also like the option override as a "hint" to the individual who is building packageX that the testsuite _should_ be run. I'll keep using my modified pacman-3.2.2 until I finish the current rebuild, but after that I'd be happy to test the changes. I have no interest in maintaining my own set of patches. :) As a side note, I've modified dozens of PKGBUILDs to implement this change, and I'm rather clueless as to why all the || return 1 statements exist since set -e is in use. Are they cruft left behind from an earlier version of makepkg that didn't bail on the first error? Also, my patch actually just runs run_build() with an argument (the arg being the name of the PKGBUILD function to run) so there was no code duplication. In run_build() I put in a simple: cd "${srcdir}/${pkgname}-${pkgver}" || cd "${srcdir}" as it seemed silly to have a cd command in every single PKGBUILD when a good number of tarballs follow the ${pkgname}-${pkgver} naming scheme. I don't know if you have added that feature or not. Especially with more than one function in PKGBUILD, cd would have to be duplicated (and still will for non-standard source tarballs). A function for determining that name might be useful, though, and would help in all cases except where the build dir != source dir (like glibc). Anyway, just food for thought! -- Jeff My other computer is an abacus.

This change was wrong, popen does require /bin/sh in a subchroot. 1) pacman -S lilo -r root Notice no error 2) rm root/bin/sh ; pacman -S lilo -r root Notice an error : error: scriptlet failed to execute correctly Actually, we already get an explicit error here, when popen is run, so there is no need to check for bin/sh explicitely. Besides this check was problematic in some cases. For example, bash itself has a scriptlet, but only post_install and post_upgrade, no pre_install and pre_upgrade. However, since bash has a scriptlet, runscriptlet will also be called before bash is installed. It won't do anything since the scriptlet has no pre_install function. But if we keep the check, we will still get "error : no /bin/sh".

Reading man fork, this part caught my attention: * The child inherits copies of the parent's set of open file descriptors. Each file descriptor in the child refers to the same open file description (see open(2)) as the corresponding file descriptor in the parent. This means that the two descriptors share open file status flags, current file offset, and signal-driven I/O attributes (see the description of F_SETOWN and F_SETSIG in fcntl(2)). Since the open file descriptors are inherited, it is probably a good idea to flush them before forking.

[pacman-dev] [PATCH 1/2] libalpm: sync changes to disk when appropriate
by Dan McGee 15 Mar '09

15 Mar '09

We don't make calls to fsync() or fdatasync() when we are attempting to do something transactionally, such as writing out one of our DB entries. Add a call to fdatasync() when we write DB entries, and also ensure we sync our log changes to disk whenever we close it. Another important thing to ensure is that we commit our database additions and removals as well by syncing the DB directory itself.
