2015-12-05move signal handlers to sighandler.[ch]Andrew Gregory
Signals are special because they run asynchronously, making them non-trivial to handle correctly. Move the handlers a separate file to offset them from the normal code and make them easier to separate into individual functions without further cluttering pacman.c Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-05avoid unsafe functions in signal handlerAndrew Gregory
signal(7) lists a set of functions that can safely be called from within a signal handler. Even fileno and strlen are not guaranteed to be safe. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-05remove SIG_IGN check when setting signal handlerAndrew Gregory
Our signal handler provides a way to gracefully interrupt a transaction and should always be set. The check appears to have originally been copied directly from the glibc manual. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-05do not catch SIGTERMAndrew Gregory
On SIGTERM pacman was exiting immediately, even in the middle of a transaction. In this case we should leave the lock file in place as an indication that the database may not be in a consistent state.

2015-12-05pacman: exit without memory cleanup on signalsAndrew Gregory
Memory allocation/deallocation functions are not safe to call from signal handlers. Just remove the lock file if there is one and exit immediately. Fixes: FS#46375, FS#45995, FS#47011 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-05add and expose alpm_unlockAndrew Gregory
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>
2015-12-05handle_unlock: return 0 if lockfile == NULLAndrew Gregory
Returning -1 is useless since we don't provide any way to determine why it failed. 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 Gregory
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. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
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.

2015-12-05Detect potential conflict when symlink to directory is changing to directoryAllan McRae
When a symlink to a directory is changing to a directory, any package file inside the new directory can create an unexpected conflict with the filesystem. Reported by Neofytos and Luca from Chakra. Signed-off-by: Allan McRae <allan@archlinux.org>
2015-12-04Add large file support CFLAGS to pkgconfig fileAllan McRae
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>
2015-11-29run_chroot: always clear script output bufferAndrew Gregory
If the script output does not end in a newline there could still be data in the buffer after the poll loop. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-11-23lint_pkgbuild/variable: increase robustnessAllan McRae
Approach the detection of variables of the wrong type using an approach similar to that used for construction of .SRCINFO files. While doing silly things in bash could still result in false negatives, this approach should be very robust to generatinf false positives results. Signed-off-by: Allan McRae <allan@archlinux.org>

2015-11-05Refactor lint_source to work with earlier versions of BashAaron Campbell
Negative subscripts to indexed arrays are not supported before 4.2. However, since substring expansion works on arrays, we can specify an offset of -1 to be taken relative to one greater than the maximum index of the specified array (see Parameter Expansion section of the bash man page). This works with both Bash 4.1 and 4.2, and 4.1 is already the oldest supported by pacman. Signed-off-by: Aaron Campbell <aaron@monkey.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-10-28_alpm_hook_run: check path length before copyingAndrew Gregory
If a hook path equals or exceeds PATH_MAX characters the path will be left unterminated. Pre-calculating the path length also allows us to use the more efficient memcpy over strncpy. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2015-10-28makepkg: fix $pkgname element duplicationBenjamin Yates
run_split_packaging did not preserve the $pkgname array correctly, and would create duplicate entries in the list during restore. After restoring the backup (a b c) would become (a b c b c). This probably went unnoticed because during --install, pacman would reconcile the duplicates. Signed-off-by: Allan McRae <allan@archlinux.org>
