2016-02-23make alpm_unlock and trans_interrupt async safeAndrew Gregory3-4/+10
RET_ERR calls _alpm_log which includes calls that are not safe for use in asynchronous signal handlers (see signal(7)). Replace it in functions called from our signal handlers with a new macro RET_ERR_ASYNC_SAFE which is identical except that it lacks the call to _alpm_log.

2016-02-23alpm_run_chroot: always connect parent2child pipeAndrew Gregory1-7/+6
Commit e374e6829cea3512f0b4a4069c5a6168f0f8d8a0 closed stdin before running scripts/hooks. This left the exec'd process with no file descriptor 0. If the process subsequently opened a file it would be assigned fd 0, and could potentially be confused for stdin. Connecting and immediately closing the parent2child pipe ensures that the child has an fd 0 and that it is empty.

2016-02-23ensure gpgdir has a trailing slashAndrew Gregory1-9/+3
init_gpgme checks for various paths under gpgdir by concatenating them directly, giving warning messages incorrectly if gpgdir does not end with '/'. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2016-02-23do not rely on localdb for hook matchingAndrew Gregory5-13/+17
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. Fixes FS#47996 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2016-02-21only remove pacnew file if it is newAndrew Gregory1-3/+7
Check if we overwrote an exiting pacnew file before unlinking it. Otherwise, updating to a version with an unchanged file would delete existing pacnew files. FS#47993 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2016-01-15add alpm_list_appendAndrew Gregory2-10/+25
alpm_list_add always returns the provided list making it impossible for callers to check whether or not the operation actually succeeded without manually comparing the list length before and after. alpm_list_append instead returns a pointer to the newly created list item so that success can be checked.

2016-01-04Make alpm_graph state signedness explicitRikard Falkeborn1-1/+1
The signedness of char is implementation defined. Since the alpm_graph state is clearly meant to be signed, make the signedness explicit. This fixes bugs on systems where char is unsigned, in comparissons of the following type: if(v.state == -1) which, if state is unsigned, will never be true due to integer promotion rules. Fixes failing test/pacman/tests/sync012.py when compiling with -funsigned-char. Fixes two warnings [-Wtype-limits] for comparissons with -1 when compiling with -funsigned-char.

2016-01-04Do not warn about missing files in NoExtractAllan McRae1-2/+4
The CheckSpace option checks the size of all files in a package being replaced and gives a warning when it can not read the file. However, files in NoExtract are expected to be missing and should not be warned about. Fixes FS#47470. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-15alpm: Abort ASAP on failure in pre-transaction hooksOlivier Brunel1-0/+8
There is no need to run any/remaining pre-transaction hooks as soon as a failure has occured, which will lead to aborting the transaction. So if an error occured during the first phase (reading directories/parsing files), or as soon as a hook flagged abort_on_fail does fail, we stop processing them and return. (For post-transaction hooks, all hooks are run regardless since there's no aborting.) Signed-off-by: Olivier Brunel <jjk@jjacky.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-15alpm-hooks: add Description fieldAllan McRae2-0/+7
The "Description" field allows a hook to provide a some text for frontends to use in describing what the hook is doing. For example: Description = updating info page directory Signed-off-by: Allan McRae <allan@archlinux.org>

2015-12-15Add ALPM_EVENT_TRANSACTION_{START,DONE} eventsAllan McRae2-0/+9
This provides a way to detect when the processing of package changes starts, allowing pacman to delineate hook output and package installation/removal output. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-15Add events ALPM_EVENT_HOOK_{START,DONE}Olivier Brunel3-9/+33

2015-12-15Collect all triggered hooks before running themAllan McRae1-1/+10
Having a first pass that checks which hooks are triggered followed by a second pass of the triggered hooks allows us to only provide output when a hook is actually triggered. Signed-off-by: Allan McRae <allan@archlinux.org>

2015-12-05alpm_initialize: Fix double slash in sys hook dir pathDavid Macek1-2/+5
The path of the default system hook directory was created by concatenating `myhandle->root` (usually "/"), and SYSHOOKDIR (usually "/usr/share/libalpm/hooks/"), resulting in "//usr/share/libalpm/hooks/". Fix this by skipping the initial slash from SYSHOOKDIR. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-05db_update: always clear db flags after updateAndrew Gregory1-22/+23
Signature downloading and DB validation was being based on the most recent download status for the DB. If a DB successfully downloaded but a signature did not, db_update would move to the next server. If the next server tried does not have a more recent copy of the DB, db_update would not download the DB again and would forget that the DB had previously been updated. In this case it would skip validation entirely, leaving an updated DB with the original validation status.

2015-12-05add and expose alpm_unlockAndrew Gregory2-2/+18
alpm_unlock is a limited version of alpm_release that does nothing but the actual unlinking of the lock file and is therefore safe to call from signal handlers. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-12-05skip conflicts resolved by file replacementAndrew Gregory1-0/+15
When replacing a file with a directory, any files inside the new directory cannot possibly exist on the filesystem and can be skipped. This allows cross-package symlink-to-directory transitions when there are files with the same name under both the symlinked directory and the new directory.

2015-12-05always unlink files before extractionAndrew Gregory1-8/+3
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.

2015-12-04Add large file support CFLAGS to pkgconfig fileAllan McRae1-1/+1
Large file support is enabled by our configure script as required. If anything linking to libalpm does not also define large file support, there will be differences in the size of off_t which are not caught until runtime. Add the required CFLAGS to the pkg-config file so that users of libalpm know what flags are required. Signed-off-by: Allan McRae <allan@archlinux.org>

2015-08-08libalpm: Force update when database is marked as corrupted.Sebastian Lackner1-0/+5
When a database and its signature is updated non-atomically on a server, there is a window where a user may update the database but grab the old signature. The database is marked as invalid by libalpm, which can be fixed by forcing a refresh (assuming the server has caught up and the user realizes what has happened) or with a future update of the repo. Work around this by forcing a repository refresh whenever a database is invalid. Signed-off-by: Sebastian Lackner <sebastian@fds-team.de> Signed-off-by: Allan McRae <allan@archlinux.org>
