* Update copyright years for 2016Allan McRae2016-01-04
| | | | | | make update-copyright OLD=2015 NEW=2016 Signed-off-by: Allan McRae <allan@archlinux.org>
* remove soft interrupt handler before cleanupAndrew Gregory2015-12-05
| | | | | | | | 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>
* extract soft interrupt handlersAndrew Gregory2015-12-05
| | | | | | | | Delays handler setup until after config is set to a valid value to avoid a segmentation fault. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* extract SIGSEGV handlerAndrew Gregory2015-12-05

* move signal handlers to sighandler.[ch]Andrew Gregory2015-12-05
| | | | | | | | | | 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>
* avoid unsafe functions in signal handlerAndrew Gregory2015-12-05
| | | | | | | | 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>
* remove SIG_IGN check when setting signal handlerAndrew Gregory2015-12-05
| | | | | | | | | | | 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>
* do not catch SIGTERMAndrew Gregory2015-12-05
| | | | | | | | | 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. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman: exit without memory cleanup on signalsAndrew Gregory2015-12-05
| | | | | | | | | | | 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>

* Use ARRAYSIZE macro for non-string array size computationPierre Neidhardt2015-10-27
| | | | | Signed-off-by: Pierre Neidhardt <ambrevar@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman: add user hook directoriesAndrew Gregory2015-10-18
| | | | Signed-off-by: Allan McRae <allan@archlinux.org>
* Add regex search option to sync database file searchingAllan McRae2015-07-15
| | | | | | e.g. pacman -Fsx kcm.*print.*\.so Signed-off-by: Allan McRae <allan@archlinux.org>
* Prototype pacman files database operationsAllan McRae2015-07-15
| | | | | | | Add the -F/--files operations, -s/--sync support and nd provide dummy functions for -s/--search, -l/-list and -o/--owns. Signed-off-by: Allan McRae <allan@archlinux.org>
* Fix formatting in parsearg_upgradeAllan McRae2015-07-14

* Update copyright notices for 2015Allan McRae2015-02-01
| | | | Signed-off-by: Allan McRae <allan@archlinux.org>
* Integrate testdb into pacmanAllan McRae2015-01-02
| | | | | | | | | | | | 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>
* shut up GCC on -Wmaybe-initialized warningsDave Reisner2014-12-18
| | | | | | Admittedly, these are totally bogus, but a clean build is a happy build. Signed-off-by: Allan McRae <allan@archlinux.org>
* Fix pointer declarations to be globally consistentMicah Saint Germain2014-12-18
| | | | | | | | | | | | Refactored inconsistent pointer declarations to better improve consistency throughout the pacman codebase which will, in turn, increase readability to the user. Expected format of a pointer declaration: `typename *varname` Signed-off-by: Micah Saint Germain <micah@lexme.org> Signed-off-by: Allan McRae <allan@archlinux.org>
* Add --assume-installed to pacman --helpFlorian Pritz2014-11-05
| | | | | Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman: add --confirm optionAndrew Gregory2014-10-13
| | | | | | | | | --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>
* Add --assume-installed optionFlorian Pritz2014-09-30
| | | | | | This allows to ignore specific dependencies. Signed-off-by: Florian Pritz <bluewind@xinu.at>
* pacman.c: Add -gg, -ii, and -yy to help summaryJohannes Löthberg2014-09-23
| | | | | | | | | | | | | The sync help summaries was missing the information about: * -gg: View all groups and members * -ii: View extended information * -yy: Force refresh even if DBs are up to date Fixes FS#41388. Original-work-by: Earnestly <zibeon@gmail.com> Signed-off-by: Johannes Löthberg <johannes@kyriasis.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman: set SA_RESTART for signal handlerAndrew Gregory2014-09-23
| | | | | | | Calling a signal handler interrupts some functions, most notably read() and therefore fgets(). Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com>
* pacman.c: simplify stdin parsingAndrew Gregory2014-08-04
| | | | | | | | Incorporate memory exhaustion and end-of-stream checks into the main loop. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* cache terminal size, add SIGWINCH handler to resetDave Reisner2014-06-29
| | | | | | | | | | | | | 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.
* Revert refactoring in fa0c1e14Allan McRae2014-06-29
| | | | | | | 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>
* pacman: Correct signal handler comment and refactorSilvan Jegen2014-06-24
| | | | | | | | | | | | | 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>
* Move break to a new line for consistencyHong Shick Pak2014-06-23
| | | | | | | | This was the only break that didn't have its own line in the function parsearg_query. Signed-off-by: Hong Shick Pak <hong@hspak.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* Clarify that -Ql prints a file listAllan McRae2014-05-25

* pacman: use exit status 0 for --help and --versionAndrew Gregory2014-01-30
| | | | | | | The user requesting usage or version information is not an error. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* Remove ts and sw from vim modeline when noet is setFlorian Pritz2014-01-28
| | | | | | | | | | | | 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. Command run: find . -type f -exec sed -i '/vim.* noet/s# ts=2 sw=2##' {} + Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman.c: free string commandline optionsAndrew Gregory2014-01-28
| | | | | | | Plugs a memory leak when values were passed twice. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman.c: remove unnecessary optarg checksAndrew Gregory2014-01-28
| | | | | | | | | | 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.

* Fix whitespace and other formatting issuesJason St. John2013-11-15
| | | | | | | | | This commit: -- replaces space-based indents with tabs per the coding standards -- removes extraneous whitespace (e.g. extra spaces between function args) -- adds missing braces for a one-line if statement Signed-off-by: Jason St. John <jstjohn@purdue.edu>
* check for -1 return value from getopt_longAndrew Gregory2013-10-31
| | | | | | | | | getopt_long returns -1 when it has finished parsing all args. A return value of 0 indicates that a flag was set directly by getopt_long and parsing should continue. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* Use getuid instead of geteuidVladimir A. Nazarenko2013-10-31
| | | | | | | | | | | If someone gives the pacman binary setuid permissions, the geteuid check allows it to start running but subsequently fail. As we do not support setting pacman setuid, use getuid to check permissions instead. FS#37174. Signed-off-by: Vladimir A. Nazarenko <naszar@ya.ru> Signed-off-by: Allan McRae <allan@archlinux.org>
* Fix detection of joint --native and --foreign usageAllan McRae2013-10-31
| | | | Signed-off-by: Allan McRae <allan@archlinux.org>
* include invalid options in error messagesAndrew Gregory2013-10-14
| | | | | | | | On invalid combinations of flags we were only printing the unhelpfully vague message "invalid option". Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* pacman: die on invalid option combinationsAndrew Gregory2013-10-14
| | | | | | | Fixes FS#20950 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* rename PKG_LOCALITY_LOCAL -> PKG_LOCALITY_NATIVEAndrew Gregory2013-10-14
| | | | | | | | | PKG_LOCALITY_LOCAL was confusing because the enum is used with -Q, so all packages are "local". Also reversed the config->op_q_locality assignment so that the locality matches the option used. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* do not run scriptlets with --dbonlyAndrew Gregory2013-10-14
| | | | | | | | Running an install script does not fall under "Adds/removes the database entry only." Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* imply --print from --print-formatAndrew Gregory2013-10-14
| | | | | | | | | --print-format is totally useless without --print. Implying --print will also save us the hassle of checking it when we add transaction option validation. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
* use non-ascii identifiers for optflagsAndrew Gregory2013-10-14
| | | | | | | | | | | | | | | | | Removes the overlap between optflags for different operations that allowed non-sensical combinations of flags such as: $ pacman -Si --changelog $package --changelog is -c, meaning --clean for -S $ pacman -Q --sysupgrade --sysupgrade is -u, meaning --upgrades for -Q Also add a few missing braces.
