2011-07-28Revamp signing checksDan McGee
This ensures we are actually making correct use of the information gpgme is returning to us. Marginal being allowed was obvious before, but Unknown should deal with trust level, and not the presence or lack thereof of a public key to validate the signature with. Return status and validity information in two separate values so check methods and the frontend can use them independently. For now, we treat expired keys as valid, while expired signatures are invalid. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-21Convert package filelists to an array instead of linked listDan McGee
This accomplishes quite a few things with one rather invasive change. 1. Iteration is much more performant, due to a reduction in pointer chasing and linear item access. 2. Data structures are smaller- we no longer have the overhead of the linked list as the file struts are now laid out consecutively in memory. 3. Memory allocation has been massively reworked. Before, we would allocate three different pieces of memory per file item- the list struct, the file struct, and the copied filename. What this resulted in was massive fragmentation of memory when loading filelists since the memory allocator had to leave holes all over the place. The new situation here now removes the need for any list item allocation; allocates the file structs in contiguous memory (and reallocs as necessary), leaving only the strings as individually allocated. Tests using valgrind (massif) show some pretty significant memory reductions on the worst case `pacman -Ql > /dev/null` (366387 files on my machine): Before: Peak heap: 54,416,024 B Useful heap: 36,840,692 B Extra heap: 17,575,332 B After: Peak heap: 38,004,352 B Useful heap: 28,101,347 B Extra heap: 9,903,005 B Several small helper methods have been introduced, including a list to array conversion helper as well as a filelist merge sort that works directly on arrays.

2011-07-18Fix test suite when GPGME is disabledDan McGee
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>

2011-07-18signing.c: check if needed files are readableFlorian Pritz
If we can't read the keyring, gpgme will output confusing debug information and fail to verify the signature, so we should log some debug information. Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-18Handle removal of empty directories properlyDan McGee
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 McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-14Allow fileconflict if unowned file moving into backup arrayDan McGee
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 McGee
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.

2011-07-05lib/dload: prevent large file attacksDave Reisner
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>
2011-07-05dload: handle irregular URLsDave Reisner
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>
2011-07-05Remove 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>

2011-07-05Simplify alpm_list_previousAllan McRae
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.

2011-07-05Allow invalid sync DBs to be returned by the libraryDan McGee
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 McGee
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 McGee
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 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.
