* Remove checksum access indirectionDan McGee2011-08-15
| | | | | | | | | These items are never present in anything but sync databases, nor do we even try to load them from the local database. Remvoe the indirection meant to allow the caching layer to work since it will never do anything anyway. Signed-off-by: Dan McGee <dan@archlinux.org>
* Load and allow access to sha256sumDan McGee2011-08-15
| | | | | | | | | This adds a field in the package struct for this checksum type as well as allowing access via the API to it. The frontend is now able to display any read value. Note that this does not implement any use or verification of the value internally. Signed-off-by: Dan McGee <dan@archlinux.org>
* Store a package info level flag if we fail to load dataDan McGee2011-08-08
| | | | | | | | | | | | | | | | | If we are missing a local database file, we get repeated messages over and over telling us the same thing, rather than being sane and erroring only once. This package adds an INFRQ_ERROR level that is added to the mask if we encounter any errors on a local_db_read() operation, and short circuits future calls if found in the value. This fixes FS#25313. Note that this does not make any behavior changes other than suppressing error messages and repeated code calls to failure cases; we still have more to do in the "local database is hosed" department. Also make a small update to the wrong but unused flags set in be_package; using INFRQ_ALL there was not totally correct. Signed-off-by: Dan McGee <dan@archlinux.org>
* Don't trim whitespace when reading database entriesDan McGee2011-08-02
| | | | | | | | | | | We don't write with extra or unknown whitespace, so there is little reason for us to trim it when reading either. This also fixes the hopefully never encountered "paths that start or end with spaces" issue, for which two pactests have been added. The tests also contain other evil characters that we have encountered before and handle just fine, but it doesn't hurt to ensure we don't break such support in the future.

* Convert package filelists to an array instead of linked listDan McGee2011-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Move alpm filelists to a struct objectDan McGee2011-07-03
| | | | | | | | | | | | | | | | 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>

* Make local_db_read() private to the local backendDan McGee2011-06-30
| | | | | | | | | | | | | | | | | | | 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>

* Make sync DB reading a bit more flexibleDan McGee2011-06-24
| | | | | | | | | | | We can reorganize things a bit to not require reading a directory-only entry first (or at all). This was noticed while working on some pactest improvements, but should be a good step forward anyway. Also make _alpm_splitname() a bit more generic in where it stores the data it parses. Signed-off-by: Dan McGee <dan@archlinux.org>
* Add a 'valid' flag to the database objectDan McGee2011-06-24
| | | | | | | | | | | | | | 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>
* Move database 'version' check to registration timeDan McGee2011-06-24
| | | | | | | | This is another step toward doing both local database validation (ensuring we don't have depends files) and sync database validation (via signatures if present) when the database is registered. Signed-off-by: Dan McGee <dan@archlinux.org>
* Convert backup list to new pmbackup_t typeDan McGee2011-06-22
| | | | | | | | This allows us to separate the name and hash elements in one place and not scatter different parsing code all over the place, including both the frontend and backend. Signed-off-by: Dan McGee <dan@archlinux.org>

* Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee2011-06-09
| | | | | | | | This requires a lot of line changes, but not many functional changes as more often than not our handle variable is already available in some fashion. Signed-off-by: Dan McGee <dan@archlinux.org>
* New signatures for alpm initialize and releaseDan McGee2011-06-07
| | | | | | | | | | | 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>

* Add handle attribute to pmdb_t structDan McGee2011-06-03
| | | | | | | | This is the first step in a long process to remove our dependence on the global handle variable we currently share in libalpm, with the goal to make things a bit more thread-safe and re-entrant. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove ALPM_LOG_FUNC macroDan McGee2011-06-03
| | | | | | | | | 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.

* | Remove indirection on get_name and get_version operationsDan McGee2011-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For a package to be loaded from any of our backends, these two fields are always required upfront. Due to this fact, we don't need them to be backend-specific operations and can just refer to the field directly. Additionally, our static (and thus private) cache package accessors had a NULL check on pkg before returning the relevant field. Eliminate this since they only way they are ever called is via the packages attached callback struct, which would have caused the NULL pointer dereference in the first place.

A huge checkin, but if we just do it and let people adjust the pain will end soon enough.

* Ensure d_type is not DT_UNKNOWN before relying on itDan McGee2011-03-01
| | | | | | | | | | Fixes FS#23090, a rather serious problem where the user was completely unable to read the local database. Even if entry->d_type is available, the given filesystem providing it may not fill the contents, in which case we should fall back to a stat() as we did before.

* Handle null pkgcache for local/sync db_populate()Pang Yan Han2011-02-07
| | | | | | | | | | | | | | | In sync_db_populate() and local_db_populate(), a NULL db->pkgcache is not caught, allowing the functions to continue instead of exiting. A later alpm_list_msort() call which uses alpm_list_nth() will thus traverse invalid pointers in a non-existent db->pkgcache->list. pm_errno is set to PM_ERR_MEMORY as _alpm_pkghash_create() will only return NULL when we run out of memory / exceed max hash table size. The local/sync db_populate() functions are also exited. Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
