2011-08-09Conflict comparison performance enhancementsDan McGee1-0/+2
* Add *_hash fields to conflict struct and populate them * Remove unnecessary backwards string comparisons Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-09Attempt to fix up some of the brokenness around failed package loadsDan McGee1-0/+1
This is a bit of a mess, due to the fact that we have a progress meter running. It is also ironic that we are in the midst of a method named "commit" when we haven't done a damn thing yet, and can still fail hard if either a checksum or signature is invalid or unrecognized. Adapt the former test_md5sum method to be invoked for any of the various failure types, which at least gives the user some indication of what packages are failing. A second patch will be needed to actually show worthwhile error codes, but this is going to involve modifying the actual data passed with the callback. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-29Revamp signing checksDan McGee1-5/+17
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 McGee1-2/+9
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.

2011-07-14Make alpm_db_set_pkgreason() arguments more saneDan McGee1-3/+4
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>
2011-07-05Allow frontend access to signature verification informationDan McGee1-0/+2
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>
2011-07-05signing: move to new signing verification and return schemeDan McGee1-20/+47
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.

2011-07-03Move alpm filelists to a struct objectDan McGee1-0/+7
This allows us to capture size and mode data when building filelists from package files. Future patches will take advantage of this newly available information, and frontends can use it as well. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-27Remove setter for DB signature levelDan McGee1-1/+0

2011-06-24Add a 'valid' flag to the database objectDan McGee1-0/+1
Start by converting all of our flags to a 'status' bitmask (pkgcache status, grpcache status). Add a new 'valid' flag as well. This will let us keep track if the database itself has been marked valid in whatever fashion. For local databases at the moment we ensure there are no depends files; for sync databases we ensure the PGP signature is valid if required/requested. The loading of the pkgcache is prohibited if the database is invalid. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-24Do database signature checking at load timeDan McGee1-1/+4
This is the ideal place to do it as all clients should be checking the return value and ensuring there are no errors. This is similar to pkg_load(). We also add an additional step of validation after we download a new database; a subsequent '-y' operation can potentially invalidate the original check at registration time. Note that this implementation is still a bit naive; if a signature is invalid it is currently impossible to refresh and re-download the file without manually deleting it first. Similarly, if one downloads a database and the check fails, the database object is still there and can be used. These shortcomings will be addressed in a future commit.

2011-06-22Convert backup list to new pmbackup_t typeDan McGee1-0/+6

2011-06-16Make pmfileconflict_t type publicDan McGee1-17/+19
This removes the need to write accessor methods for every type we have, and simplifies the API. Any type that doesn't need magic* can be converted in this fashion to make it easier for frontend applications to use, as well as make it less of a pain to introduce new such structs in the future. * "magic" meaning something like pmpkg_t where values can be lazy loaded.
