2011-07-18Handle removal of empty directories properlyDan McGee3-6/+82
This addresses FS#25141. We shouldn't remove every empty directory we come across during the removal process unless it is truly not known to any other package. This will prevent removal of essential directories such as '/var/lock/'. This is accomplished by first checking the empty/non-empty status of a directory, which was previously done implicitly by calling rmdir() and ignoring errors. We do this to avoid the next (new) check in most cases, which is to look at all local packages to see if the to-be-removed directory is present in another packages' filelist. If we do not find it anywhere, then we remove it, else we keep the file around. The pactest has been updated to test more cases, as well as finding a flaw in the original expected to fail case- we need separate DIR and FILE based EXIST rules.

2011-07-14Make alpm_db_set_pkgreason() arguments more saneDan McGee2-18/+23
This can only ever operate on the local database, and a local package at that. Change the function signature to take a handle and package object, add the relevant asserts, and ensure the frontend can detect the package not found condition when finding packages to pass to this method.

2011-07-14Allow fileconflict if unowned file moving into backup arrayDan McGee5-8/+23
The bulk of this commit is adding new tests to ensure the new behavior works without disrupting old behavior. This is a relatively sane maneuver when a package adds a conf file (e.g. '/etc/mercurial/hgrc') that was not previously in the package, but it is placed in the backup array. In essence, we can treat the existing file as having always been a part of the package and do our normal compare/install as pacnew logic checks. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-06Unify package removal codeDan McGee3-109/+100
This code duplication has always been a rather clumsy casuality of fixing some past upgrade issues. Unify the removal code across upgrade and remove operations into a new _alpm_remove_single_package() method wihch makes it very clear how we handle upgrade and remove differently, via several conditionals on newpkg. This commit highlights interesting behavior such as the fact that the implicit removal in every package upgrade never gets transaction events or progress callbacks.

2011-07-06include util.h in rawstr.cDan McGee1-0/+2
Fixes "error: no previous prototype for '_alpm_raw_cmp' [-Werror=missing-prototypes]" warnings, and also prevents someone from getting the prototypes and functions out of sync. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-06lib/dload: prevent large file attacksDave Reisner4-40/+87
This means creating a new struct which can pass more descriptive data from the back end sync functions to the downloader. In particular, we're interested in the download size read from the sync DB. When the remote server reports a size larger than this (via a content-length header), abort the transfer. In cases where the size is unknown, we set a hard upper limit of: * 25MiB for a sync DB * 16KiB for a signature For reference, 25MiB is more than twice the size of all of the current binary repos (with files) combined, and 16KiB is a truly gargantuan signature. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2011-07-06dload: handle irregular URLsDave Reisner4-24/+116
URLs might end with a slash and follow redirects, or could be a generated by a script such as /getpkg.php?id=12345. In both cases, we may have a better filename that we can write to, taken from either content-disposition header, or the effective URL. Specific to the first case, we write to a temporary file of the format 'alpmtmp.XXXXXX', where XXXXXX is randomized by mkstemp(3). Since this is a randomly generated file, we cannot support resuming and the file is unlinked in the event of an interrupt. We also run into the possibility of changing out the filename from under alpm on a -U operation, so callers of _alpm_download can optionally pass a pointer to a *char to be filled in by curl_download_internal with the actual filename we wrote to. Any sync operation will pass a NULL pointer here, as we rely on specific names for packages from a mirror. Fixes FS#22645. Signed-off-by: Dave Reisner <d@falconindy.com>
2011-07-06Remove most usages of strncmp()Dan McGee1-1/+1
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>

2011-07-05Simplify alpm_list_previousAllan McRae3-7/+6
We can readily detect the first node in a list by checking if node->prev->next is NULL. So there is no need to pass the head of the list to this function and its prototype now looks like all the other item accessors.

2011-07-05Remove alpm_list_firstAllan McRae2-17/+0
The only thing this accessor did was remove the const qualifier given our entire list implementation requires passing around the head anyway. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Allow invalid sync DBs to be returned by the libraryDan McGee3-13/+9
They are placeholders, but important for things like trying to re-sync a database missing a signature. By using the alpm_db_validity() method at the right time, a client can take the appropriate action with these invalid databases as necessary. In pacman's case, we disallow just about anything that involves looking at a sync database outside of an '-Sy' operation (although we do check the validity immediately after). A few operations are still permitted- '-Q' ops that don't touch sync databases as well as '-R'. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Allow frontend access to signature verification informationDan McGee2-2/+22
Show output in -Qip for each package signature, which includes the UID string from the key ("Joe User <joe@example.com>") and the validity of said key. Example output: Signatures : Valid signature from "Dan McGee <dpmcgee@gmail.com>" Unknown signature from "<Key Unknown>" Invalid signature from "Dan McGee <dpmcgee@gmail.com>" Also add a backend alpm_sigresult_cleanup() function since memory allocation took place on this object, and we need some way of freeing it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Correctly check the GPG error codesDan McGee1-2/+2
The error code is in fact a bitmask value of an error code and an error source, so use the proper function to get only the relevant bits. For the no error case, this shouldn't ever matter, but it bit me when I was trying to compare the error code to other values and wondered why it wasn't working, so set a good example. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05signing: move to new signing verification and return schemeDan McGee13-115/+237
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.

2011-06-30Make local_db_read() private to the local backendDan McGee5-32/+27
There is little need to expose the guts of this function even within the library. Make it static in be_local.c, and clean up a few other things since we know exactly where it is being called from: * Remove unnecessary origin checks in _cache_get_*() methods- if you are calling a cache method your package type will be correct. * Remove sanity checks within local_db_read() itself- packages will always have a name and version if they get this far, and the package object will never be NULL either. The one case calling this from outside the backend was in add.c, where we forced a full load of a package before we duplicated it. Move this concern elsewhere and have pkg_dup() always force a full package load via a new force_load() function on the operations callback struct. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-30Fix a few warnings pointed out via clang scan-buildDan McGee4-15/+14
