2018-05-14Remove all modelines from the projectEli Schwartz
Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2018-05-12Fix gcc8 warnings.Eli Schwartz
Attempting to compile pacman with gcc8 results in several warnings like: remove.c: In function ‘unlink_file.isra.4’: remove.c:407:34: warning: ‘.pacsave.’ directive output may be truncated writing 9 bytes into a region of size between 1 and 4096 [-Wformat-truncation=] Fix by adding checks to error out if snprintf tries to reserve a truncated filename. Because the return values are checked, gcc delegates the truncation response to our code instead of throwing warnings.

2017-04-16unlink_file: strip trailing slashesAndrew Gregory
If the user replaces a directory with a symlink, libalpm would get confused because the trailing slash causes system calls to resolve the symlink. This leads to errors and a misleading message during upgrades. Even though libalpm does not support this, it should not be giving misleading errors. Also adds an overflow check.

2014-03-03Add events on pacnew/pacsave/pacorig file creationOlivier Brunel
ALPM still adds a warning to the log, but doesn't emit an event about said warning, instead using a specific event to let the frontend what happened/how to inform the user. Note that there are 2 cases for installing a .pacnew file, to not overwrite user changes and because file is in NoUpgrade. In the later case the warning was a bit different: it happened before and said "extracting" instead of "installed." Now both happen after and are phrased the same.

2014-03-03restrict transaction package originsAndrew Gregory
This moves the "wrong args" error up from trans_commit to add_pkg when used with a local pkg and adds the error for remove_pkg when used with a sync pkg, which currently just removes the db entry.

2014-03-03Update the event callbackOlivier Brunel
Instead of using two void* arguments for all events, we now send one pointer to an alpm_event_t struct. This contains the type of event that was triggered. With this information, the pointer can then be typecasted to the event-specific struct in order to get additional arguments.

2013-11-15log important events from the backendAndrew Gregory
This ensures that important events will be logged and consistent regardless of the frontend. The need for global context in the event callback is also removed. The event is logged before any post_* scripts run, so this also moves the post_* script output underneath the event in the log.

2013-10-31sortbydeps: include local pkgs in dep graphAndrew Gregory
Detecting indirect dependencies by traversing a package's entire dependency tree is prohibitively slow for larger transactions. Instead add local packages to the dependency graph. This additionally requires delaying dependency ordering for sync operations so that removed packages may be excluded from dependency detection. tests/sync012.py was also updated to ensure that the dependency cycle was actually detected.

2013-03-07Do not resolve every local package filelist on removeAllan McRae
Although technically correct, this results in my system taking ~30 seconds to resolve all filelists when removing a package that has a directory not owned by any package. The check for if any package own the empty directory is a rare enough occurance, and it will be even rarer when that directory has a directory symlink in its path, so just revert this at this stage. Signed-off-by: Allan McRae <allan@archlinux.org>
2013-02-24use resolved_path for filelist_containsAndrew Gregory
alpm_filelist_contains was being used to search for resolved paths, but searching in the unresolved paths, causing it to miss matches. We always search unresolved paths and search the resolved paths if available because _alpm_filelist_resolve is not public and requires a context handle, so it can't be called from alpm_filelist_contains.

2013-02-16libalpm: never attempt to remove a mountpointDave Reisner
Arch Linux typically runs into this with /sys when upgrading the filesystem package in build chroots, but LXC users might also run into this, since their /sys is shared from the host and must, for security reasons, be mounted RO. I've neglected to add any tests for this because they would require root in order to run. Current tests all pass with this patch and I've confirmed the desired behavior in a VM. Incidentally, the first hunk of this patch (skipping can_remove_file checks for directories) resolves the case of API mountpoints being removed since they eventually fall into unlink_file and fail with "contains files". However, this patch should still be the Right Thing To Do™, as we can't possibly remove a directory that is also a mountpoint. Signed-off-by: Dave Reisner <dreisner@archlinux.org> [Allan] Do not skip checking if directories can be removed. Instead test if directories are mountpoints in can_remove_file.

2013-01-04Save backup files with extension .pacsave.nPang Yan Han
Teach pacman to save backup files with extension .pacsave.n, where n is a positive integer. The current backup file shall be saved as <name>.pacsave, while existing .pacsave.n files will be renamed to <name>.pacsave.n+1 Example: 1. You have subversion installed in your local repo. /etc/conf.d/svnserve is a file to be backed up. It contains local modifications 2. You remove subversion from your repo. /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave 2. You install subversion again 3. You edit /etc/conf.d/svnserve 4. You remove subversion. The existing /etc/conf.d/svnserve.pacsave is renamed to /etc/conf.d/svnserve.pacsave.1 and /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Rebased from original email and adjusted for util-common usage.

2012-08-02Move filelist functions into separate source fileDan McGee
We have a few of these and might as well gather them together.

2011-12-23Rework package removal codeDan McGee
Extract the actual unlinking of files into a new method, which eliminates a goto used for flow control. Also fix up a few small issues in the code: * Unnecessary (unsigned long) cast, use '%zd' instead * Total up errors returned from unlink_file calls and return to caller * Be consistent with scriptlets- we run pre_remove on dbonly, so we should also run post_remove. Both can be disabled by way of the --noscriptlet argument. * Don't pass an invalid pointer to oldpkg to the event callbacks; instead call the callback before we free the object.

2011-12-21include config.h via MakefilesDave Reisner
Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.
