2017-05-08extract db files with dbonlyAndrew Gregory
Some database files (install, mtree, and changelog) are extracted directly from the package, but DBONLY was skipping extraction altogether, causing those files to be missing after the transaction. Fixes #52052 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org> (cherry picked from commit 2c4511bdbe3599713811e54edbbd60e51d66ce3e)
2017-05-08libalpm: Use archive_read_extract2Armin K
archive_read_extract() forces resolution of uid/gid to names when extracting the tarball. This can lead to wrong file ownership when using pacman with -r option and when uid/gid differ in the host and in the chroot. archive_read_extract2() uses uid's and gid's only.

2016-02-23do not rely on localdb for hook matchingAndrew Gregory
Relying on localdb to determine which trigger operations should match is completely broken for PostTransaction hooks because the localdb has already been updated. Store a copy of the old version of any packages being updated to use instead.

2015-12-05always unlink files before extractionAndrew Gregory
libarchive will not extract a directory over an existing directory symlink, making it impossible to replace a symlink with a directory across packages. Adding the ARCHIVE_EXTRACT_UNLINK and ARCHIVE_EXTRACT_SECURE_SYMLINKS causes libarchive to unlink the existing symlink and prevents it from extracting any paths that contain a symlink, which we should not be doing anyway.

2015-01-21extract_single_file: use .pacnew for check filesAndrew Gregory
Prevents the need to rename the file if we end up keeping it and ensures that pacnew files always reflect the most recent version by overwriting stale copies. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2015-01-21remove support for .pacorig filesAndrew Gregory
Leave user files in place and save new config files with a .pacnew extension. This reduces the complexity of file extraction and respects the principle that pacman shouldn't modify files it didn't create. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2015-01-21extract_single_file: use full path in messagesAndrew Gregory
If an error occurs the actual path being extracted is more useful than the original path from the package file list. The original path is still used for checks that use it directly. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
2015-01-21extract_single_file: factor out db file extractionAndrew Gregory

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.

2014-01-06Use O_CLOEXEC as much as possible when opening filesDan McGee
When calling open(), use O_CLOEXEC as much as possible to ensure the file descriptor is closed when and if a process using libalpm forks. For most of these cases, and especially in utility functions, the file descriptor is opened and closed in the same function, so we don't have too much to worry about. However, for things like the log file and database lock file, we should ensure descriptors aren't left hanging around for children to touch. This patch is inspired by the problem in FS#36161, where an open file descriptor to the current working directory prevents chroot() from working on FreeBSD. We don't need this file descriptor in the child process, so open it (and now several others) with O_CLOEXEC.

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.

2013-07-30Warn when directory ownership differs between filesystem and packageAllan McRae
We currently only warn if a directory's permissions differ, but using -Qkk on my system shows that directory permissions tend to change in packages reasonably frequently without notice. Provide a warning in such cases so that it can be altered. Example output: (1/1) reinstalling nginx warning: directory ownership differs on /var/lib/nginx/proxy/ filesystem: 33:0 package: 0:0 Signed-off-by: Allan McRae <allan@archlinux.org>
2013-07-05do not check error from close(2)Dave Reisner
On operating systems we support, the behavior is always such that the kernel will do the right thing as far as invalidating the file descriptor, regardless of the eventual return value. Therefore, potentially looping and calling close multiple times is wrong. At best, we call close again on an invalid FD and throw a spurious EBADF error. At worst, we might close an FD which doesn't belong to us when a multi-threaded application opens its own file descriptor between iterations of the loop.

2013-05-29add.c: refactor backup file modification checksAndrew Gregory
The previous implementation was overly complex with unnecessary checks and nested conditionals. By reordering the tests and changing them to all be checks for positive hash matches rather than non-matches, we can collapse several cases and make the process much more linear. This removes the need to set hash_orig = "" just to reach some of the checks and corrects a faulty assumption that files are equivalent when the hashing process fails.
