* Represent bitfields as ints, not enumsIvy Foster2016-10-22
| | | | | | | | | | Many bitfield variables are declared to be enums, because they are generated using bitwise operations on enums such. However, their actual values aren't necessary members of their parent enum, so declaring them 'int' is more accurate.

* make alpm_unlock and trans_interrupt async safeAndrew Gregory2016-02-23
| | | | | | | | | | 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.

| | | | | | | | | alpm_depend_t is an exposed data type.

| | | | | | | | | | | Problems due to concurrent running instances of pacman can be difficult to diagnose. Log a warning to make it more obvious that that's what happened, that it's a bad idea, and hopefully encourage people who do things like removing the lock file to run pacman from an install script to at least be courteous enough to put it back when they're done.

* Use O_CLOEXEC as much as possible when opening filesDan McGee2014-01-06
| | | | | | | | | | | | | | | | | | | 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.

* alpm_handle: store lock file descriptorAndrew Gregory2013-11-08
| | | | | | | | | | | | | | There was a brief window between opening the file descriptor and creating a stream to it. If the process was interrupted during that window the lock file would not be removed correctly. The pid is no longer printed to the lock file as this was virtually meaningless for lock files on NFS.

* Add configuration option for Upgrade operation SigLevelAllan McRae2013-02-07
| | | | | | | | | | | | | Add LocalFileSigLevel and RemoteFileSigLevel to control the signature checking for "pacman -U <file>" and "pacman -U <url>" operations respectively. The starting value for both these options is SigLevel, if it is specified in the [options] section, or the built-in system default. The specified values override and/or supplement this initial value. Note there is no distinction between setting "Required" and "PackageRequired" as there are no database options for Upgrade operations. Signed-off-by: Allan McRae <allan@archlinux.org>

* ALPM API adjustments for sanity and consistencyDan McGee2012-02-06
| | | | | | | | | | | | | | | | | | | | | | | This makes several small adjustments to our exposed method names, and in one case, parameters. The justification here is to make methods less odd in their naming convention. If a method takes an alpm_db_t argument, the method should be named 'alpm_db_*', but perhaps more importantly, if it doesn't take a database as the first parameter, it should not. Summary of changes: alpm_db_register_sync -> alpm_register_syncdb alpm_db_unregister_all -> alpm_unregister_all_syncdbs alpm_option_get_localdb -> aplpm_get_localdb alpm_option_get_syncdbs -> aplpm_get_syncdbs alpm_db_readgroup -> alpm_db_get_group alpm_db_set_pkgreason -> alpm_pkg_set_reason All methods keep the same argument list except for alpm_pkg_set_reason; there we drop the 'handle' argument as it can be retrieved from the passed in package object.

* Allow UseDelta option to specify a delta ratioDan McGee2012-01-18
| | | | | | | | | | | | | | | | | Rework the frontend and backend to allow passing a ratio value in for UseDelta rather than having a hardcoded #define-d 0.7 value always used. This is useful for those with fast connections, who would likely benefit from tuning this ratio to lower values; it is also useful for general testing purposes. The libalpm API changes for this, but we do support the old config file format with a no-value 'UseDelta' option; in this case we simply use the old default of 0.7. We clamp the ratio values to a sane range between 0.0 and 2.0, allowing ratios above 1.0 for testing purposes. Signed-off-by: Dan McGee <dan@archlinux.org>
* Only compile delta regex onceDan McGee2012-01-02
| | | | | | | | | | | | | | | | | This reduces the number of regcomp() calls when parsing delta entries in the database from once per entry to once for the entire context handle by storing the compiled regex data on the handle itself. Just as we do with the cURL handle, we initialize it the first time it is needed and free it when releasing the handle. A few other small tweaks to the parsing function also take place, including using the stack to store the transient and short file size string while parsing it. When parsing a sync database with 1378 delta entries, this reduces the time of a `pacman -Sl deltas` operation by 50% from 0.22s to 0.12s. Signed-off-by: Dan McGee <dan@archlinux.org>
* include config.h via MakefilesDave Reisner2011-12-21
| | | | | | | | | | | | | | | Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

* Move default siglevel value from backend to frontendDan McGee2011-09-22
| | | | | | | | | | | | | | | This takes the libraries hidden default out of the equation: hidden in the sense that we can't even find out what it is until we create a handle. This is a chicken-and-egg problem where we have probably already parsed the config, so it is hard to get the bitmask value right. Move it to the frontend so the caller can do whatever the heck they want. This also exposes a shortcoming where the frontend doesn't know if the library even supports signatures, so we should probably add a alpm_capabilities() method which exposes things like HAS_DOWNLOADER, HAS_SIGNATURES, etc. Signed-off-by: Dan McGee <dan@archlinux.org>
* Use more efficient way of restoring working directoryDan McGee2011-09-19
| | | | | | | | | | | | Rather than using a string-based path, we can restore the working directory via a file descriptor and use of fchdir(). From the getcwd manpage: Opening the current directory (".") and calling fchdir(2) to return is usually a faster and more reliable alternative when sufficiently many file descriptors are available.

* Former transaction callback rename refactorDan McGee2011-09-02
| | | | | | | | | | | | | Put all the callback stuff in alpm.h in one spot, and make the following renames for clarity with the new structure: ALPM_TRANS_EVT_* --> ALPM_EVENT_* ALPM_TRANS_CONV_* --> ALPM_QUESTION_* ALPM_TRANS_PROGRESS_* --> ALPM_PROGRESS_* alpm_option_get_convcb() --> alpm_option_get_questioncb() alpm_option_set_convcb() --> alpm_option_set_questioncb() Signed-off-by: Dan McGee <dan@archlinux.org>
* Move all callbacks up to the handle levelDan McGee2011-09-02
| | | | | | | | | This was just disgusting before, unnecessary to limit these to only usage in a transaction. Still a lot of more room for cleanup but we'll start by attaching them to the handle rather than the transaction we may or may not even want to use these callbacks.

* Remove most usages of strncmp()Dan McGee2011-07-05
| | | | | | | | | | | | The supposed safety blanket of this function is better handled by explicit length checking and usages of strlen() on known NULL-terminated strings rather than hoping things fit in a buffer. We also have no need to fully fill a PATH_MAX length variable with NULLs every time as long as a single terminating byte is there. Remove usages of it by using strcpy() or memcpy() as appropriate, after doing length checks via strlen(). Signed-off-by: Dan McGee <dan@archlinux.org>
* signing: move to new signing verification and return schemeDan McGee2011-07-05
| | | | | | | | | | | | | | | | | This gives us more granularity than the former Never/Optional/Always trifecta. The frontend still uses these values temporarily but that will be changed in a future patch. * Use 'siglevel' consistenly in method names, 'level' as variable name * The level becomes an enum bitmask value for flexibility * Signature check methods now return a array of status codes rather than a simple integer success/failure value. This allows callers to determine whether things such as an unknown signature are valid. * Specific signature error codes mostly disappear in favor of the above returned status code; pm_errno is now set only to PKG_INVALID_SIG or DB_INVALID_SIG as appropriate.
