2014-03-03Remove log_cb, add ALPM_EVENT_LOG insteadOlivier Brunel
When ALPM emits a log message, it still goes through _alpm_log() but instead of calling a specific log callback, it goes as an event. Signed-off-by: Olivier Brunel <jjk@jjacky.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2014-01-28Remove ts and sw from vim modeline when noet is setFlorian Pritz
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>
2014-01-06Use O_CLOEXEC as much as possible when opening filesDan McGee
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.

2013-11-08alpm_handle: store lock file descriptorAndrew Gregory
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.

2013-02-07Add configuration option for Upgrade operation SigLevelAllan McRae
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>

2012-02-06ALPM API adjustments for sanity and consistencyDan McGee
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.

2012-01-18Allow UseDelta option to specify a delta ratioDan McGee
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>
2012-01-02Only compile delta regex onceDan McGee
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>
2011-12-21include config.h via MakefilesDave Reisner
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.

2011-09-22Move default siglevel value from backend to frontendDan McGee
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>
2011-09-19Use more efficient way of restoring working directoryDan McGee
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.

2011-09-02Former transaction callback rename refactorDan McGee
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>
2011-09-02Move all callbacks up to the handle levelDan McGee
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.

As noted by Allan, we failed pretty hard if gpgme was compiled out. With these changes, only sign001.py fails. This can/will be fixed later once we beef up the test suite with more signing tests anyway. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Remove most usages of strncmp()Dan McGee
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>
2011-07-05signing: move to new signing verification and return schemeDan McGee
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.

2011-06-24Move locking functions to handleDan McGee
These operate on the handle, and the state is stored on the handle, so move them where they belong. Up until now only the transaction stuff calls them, but this will soon change and alpm_db_update() will handle locking all on its own. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field.

2011-06-09Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee

2011-06-09Kill all remaining 'PATH_MAX + 1' usagesDan McGee
The few remaining instances were utilized for buffers in calls to snprintf() and realpath(). Both of these functions will always ensure the returned value is padded with '\0', so there is no need for the extra byte. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-07New signatures for alpm initialize and releaseDan McGee
These new method signatures return and take handle objects to operate on so we can move away from the idea of one global handle in the API. There is also another important change and that deals with the setting of root and dbpaths. These are now done at initialization time instead of using setter methods. This allows the library to operate more safely knowing that paths won't change underneath it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-07Add cachedirs one-by-one in set_cachedirs()Dan McGee

2011-06-03Remove ALPM_LOG_FUNC macroDan McGee
The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-05-19Bail early if we don't have a valid lockfile pathDan McGee
This addresses FS#24292. If one does the bad thing of not checking pm_errno after calling set_dbpath(), you may not realize the initialization process went wrong and calling trans_init() resulted in a segfault. If we don't have a lockfile path, bail out and have trans_init() fail. Also remove a ALPM_LOG_FUNC call that was causing pm_errno to return "no handle"; this was due to a log call in the handle setup (whereby the log attempts to use a callback attached to the handle). Signed-off-by: Dan McGee <dan@archlinux.org>
