2017-04-17add --sysroot optionAndrew Gregory1-6/+18
--root is not sufficient to properly operate on a mounted guest system. Using --root still uses the host system's configuration and there is no way to correctly use the guest configuration without manually modifying any Include directives. --sysroot provides an easier way to operate on a guest system by chrooting immediately after option parsing before configuration parsing or performing any operations. It is currently limited to the root user, but that's enough for restoring a guest system to a working state, which is the primary intended use case.

2017-04-12deprecate --force in favor of --overwriteAndrew Gregory1-1/+2
--force is widely misunderstood and the same effect can now be achieved with --overwrite, which is better named and can be used more safely. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2017-04-12add --overwrite option to ignore file conflictsAndrew Gregory1-0/+6
Allows for safer, more fine-grained control for overwriting files than --force's all-or-nothing approach. Implements FS#31549. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2017-04-04parse stdin as newline-separatedAndrew Gregory1-32/+23
Newline-separated input is more reliable because most of the arguments we accept over stdin can validly contain spaces but not newlines. Resolves FS#52992 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2017-01-13Introduce a 'disable-download-timeout' optionChristian Hesse1-0/+6
Add command line option ('--disable-download-timeout') and config file option ('DisableDownloadTimeout') to disable defaults for low speed limit and timeout on downloads. Use this if you have issues downloading files with proxy and/or security gateway. Signed-off-by: Christian Hesse <mail@eworm.de> Signed-off-by: Allan McRae <allan@archlinux.org>

2016-12-05Give a "success!" message on database checkPatrick Eigensatz1-0/+5
'pacman -Dk' prints a "success!" message if there were no errors. It is possible to suppress the output using the '-q / --quiet' flag.

2015-12-05remove soft interrupt handler before cleanupAndrew Gregory1-0/+1
The soft interrupt handler dereferences config, causing a segfault if it is called during cleanup. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-12-05move signal handlers to sighandler.[ch]Andrew Gregory1-58/+2
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 Gregory1-9/+7
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 Gregory1-6/+2
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 Gregory1-3/+2
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 Gregory1-2/+2
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>

2015-01-02Integrate testdb into pacmanAllan McRae1-3/+20
The functionality of testdb is now available in pacman. pacman -Dk will check the local database for consistency, and pacman -Dkk will check the sync databases. Note that unlike testdb, you can not specify individual sync databases to check as sync databases act as a whole and not individually. A single database can be checked using an alternative pacman.conf file. Signed-off-by: Allan McRae <allan@archlinux.org>
2014-12-18shut up GCC on -Wmaybe-initialized warningsDave Reisner1-2/+1

2014-12-18Fix pointer declarations to be globally consistentMicah Saint Germain1-5/+5
Refactored inconsistent pointer declarations to better improve consistency throughout the pacman codebase which will, in turn, increase readability to the user.

2014-10-13pacman: add --confirm optionAndrew Gregory1-0/+5
--confirm cancels the effect of a previous --noconfirm. This makes it easier for scripts to default to --noconfirm but allow users to override it. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2014-09-23pacman: set SA_RESTART for signal handlerAndrew Gregory1-1/+1

2014-06-29cache terminal size, add SIGWINCH handler to resetDave Reisner1-1/+4
Refactoring getcols, yet again. We do the following: 1) Introduce a static global in src/pacman/util.c 2) getcols always prefers this cached value, but will derive it from the COLUMNS environment var, the characteristics of stdout, or a sane default (in that order). 3) Introduce a SIGWINCH signal handler to reset the cached value, meaning we only call ioctl when we don't know the value. On my machine, pacman -Syy goes from ~4300 ioctl calls to 3.
2014-06-29Revert refactoring in fa0c1e14Allan McRae1-1/+1
This will cause the code to break as soon as we handle another signal such as SIGWINCH... Signed-off-by: Allan McRae <allan@archlinux.org>
2014-06-24pacman: Correct signal handler comment and refactorSilvan Jegen1-3/+3
One of the comments for this function is out of sync with the code. Since the code exhibits the more sane behavior of treating SIGINT and SIGHUB the same way (by not exiting pacman when there is a commit in flight) we adjust the comment. Given this code flow, the if/else statements can be simplified somewhat as well. Signed-off-by: Silvan Jegen <s.jegen@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2014-01-28Remove ts and sw from vim modeline when noet is setFlorian Pritz1-1/+1
Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand.

2014-01-28pacman.c: remove unnecessary optarg checksAndrew Gregory1-11/+0
getopt takes care of making sure that options that require a value have one. These checks were only added to silence clang, which no longer complains about optarg being unchecked, and newer options already use optarg unchecked.

2013-10-31check for -1 return value from getopt_longAndrew Gregory1-8/+4
