2011-06-30Make local_db_read() private to the local backendDan McGee
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>
2011-06-29Rename internal functions with grp in their nameAllan McRae
The following function renames take place for the same reasoning as the previous commit: _alpm_grp_new -> _alpm_group_new _alpm_grp_free -> _alpm_group_free _alpm_db_free_grpcache -> _alpm_db_free_groupcache _alpm_db_get_grpfromcache -> _alpm_db_get_groupfromcache Signed-off-by: Allan McRae <allan@archlinux.org>
2011-06-29Rename public functions with grp in their nameAllan McRae
Using grp instead of group is a small saving at the cost of clarity. Rename the following functions: alpm_option_get_ignoregrps -> alpm_option_get_ignoregroups alpm_option_add_ignoregrp -> alpm_option_add_ignoregroup alpm_option_set_ignoregrps -> alpm_option_set_ignoregroups alpm_option_remove_ignoregrp -> alpm_option_remove_ignoregroup alpm_db_readgrp -> alpm_db_readgroup alpm_db_get_grpcache -> alpm_db_get_groupcache alpm_find_grp_pkgs -> alpm_find_group_pkgs Signed-off-by: Allan McRae <allan@archlinux.org>

2011-06-24Add a 'valid' flag to the database objectDan McGee
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>
2011-06-24Move database 'version' check to registration timeDan McGee
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>
2011-06-24Do database signature checking at load timeDan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-13Add a helper method for retrieving the DB signature pathDan McGee
Note that is a bit different than the normal _alpm_db_path() method; the caller is expected to free the result. 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>

2011-06-03Add handle attribute to pmdb_t structDan McGee
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>
2011-04-24signing: let GPGME handle loading signatures from filesDan McGee

2011-03-23Add functions for verifying database signatureAllan McRae
Add a pmpgpsig_t struct to the database entry struct and functions for the lazy loading of database signatures. Add a function for checking database signatures, reusing (and generalizing) the code currently used for checking package signatures. TODO: The code for reading in signature files from the filesystem is duplicated for local packages and database and needs refactoring. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-03-23Added gpg verification options per repo to the config file.Xavier Chantry
Once we do this, add support for VerifySig to pactest. We just check if the repo name contains Always, Never or Optional to determine the value of VerifySig. The default is Never. pacman uses Always by default but this is not suitable for pactest.

2011-02-28Check local DB version before continuing transactionDan McGee
Ensure we have a local DB version that is up to par with what we expect before we go down any road that might modify it. This should prevent stupid mistakes with the 3.5.X upgrade and people not running pacman-db-upgrade after the transaction as they will need to. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-02-25alpm: remove public visibility of pmpkghash_tDave Reisner

2011-02-04Read pkgcache into hashAllan McRae
Read the package information for sync/local databases into a pmpkghash_t structure. Provide a alpm_db_get_pkgcache_list() method that returns the list from the hash object. Most usages of alpm_db_get_pkgcache are converted to this at this stage for ease of implementation. Review whether these are better accessing the hash table directly at a later stage.

2010-12-29Detect undefined PATH_MAXAllan McRae
POSIX does not require PATH_MAX be defined when there is not actual limit to its value. This affects HURD based systems. Work around this by defining PATH_MAX to 4096 (as on Linux) when this is not defined. Also, clean up inclusions of limits.h and remove autoconf check for this header as we do not use macro shields for its inclusion anyway.

2010-12-12Merge desc and depends files in local dbAllan McRae
Whenever depends is needed from the local db, so is desc. The only disadvantage to merging them is the additional time taken to read the depends entries when they are not needed. As depends is in general relatively small, the additional time taken to read it in will be negligable. Also, merging these files will speed up local database access due to less file seeks.

2010-10-14Move and rename splitnameAllan McRae
The splitname function is a general utility function and so is better suited to util.h. Rename it to _alpm_splitname to indicate it is an internal libalpm function as was the case prior to splitting local and sync db handling. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-14Restrict visibility of checkdbdir and get_pkgpathAllan McRae

2010-10-14Separate be_files into be_sync and be_localAllan McRae
The file be_files.c is "split" to be_local.c and be_sync.c in order to achieve separate handling of sync and local databases. Some basic clean-up of functions that are only of use for local or sync databases has been performed and some rough function renaming in duplicated code has been performed to prevent compilation errors. However, most of the clean-up and final separation of sync and local db handling occurs in following patches. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-13Move database handling utility functionsAllan McRae
Move splitname, checkdbdir, get_pkgpath into db.{h,c} as these will be needed to parse both the local and sync databases during the initial splitting. They will be moved out of db.{h,c} at to more appropriate locations at a later stage. Signed-off-by: Allan McRae <allan@archlinux.org>

2009-10-11int typing: s/unsigned short/int/ in libalpmDan McGee
After our recent screwup with size_t and ssize_t in the download code, I found the `-Wsign-conversion` flag to GCC to see if we were doing anything else boneheaded. I didn't find anything quite as bad, but we did have some goofups- most of our public unsigned methods would return -1 on error, which is a bit odd in an unsigned context.

2009-09-20Fully implement database lazy loadingDan McGee
Commit 34e1413d75 attempted to implement lazy loading of package databases. Although it took care of my main complaint (creating the database directory if it didn't exist), it didn't allow sync repos to be registered before alpm_option_set_dbpath() had been called. With this patch, we no longer compute the individual repository DB paths until necessary, allowing full lazy loading to work as intended, and allowing us to drop the extra setlibpath() calls from the frontend. This allows the changes introduced in a2cd48960 (but later reverted) to be added back in again. Signed-off-by: Dan McGee <dan@archlinux.org>

2009-01-20Remove some db abstraction crap.Xavier Chantry
These db_open and db_close looked quite useless. And they caused the db directory to be opened on a simple registering of a database. This is totally unneeded, this opening can be delayed to when we actually need it. Signed-off-by: Xavier Chantry <shiningxc@gmail.com>
2009-01-12db->pkgcache_loaded and db->grpcache_loadedNagy Gabor
Clearly the old code was more elegant (NULL cache indicated "not loaded"), but it had some drawbacks, so from now on we indicate the state of caches explicitly. Old drawbacks: When we had an empty database (unstable), libalpm called db_populate after every pkgcache access, because NULL pkgcache indicated "not loaded" state. This is not a common case, but the same situation can happen with grpcache, which is more problematic: If the user had a custom repo with no groups, grpcache was always NULL. (grpcache is also loaded per database.) Thus every get_grpcache call induced a load_grpcache operation, so the benefits of grpcache was completely lost.

2009-01-02Separate local db directory creation and db writeAllan McRae
Changelogs and install files were getting extracted into the local db folder before it was manually created. This created issues for uses with 0077 umasks and was highlighted with the new sudo handling of umasks (FS#12263). This moves the local db creation to its own function which is called before the start of package archive extraction. Also, added a check that the folder is actually created.

2008-05-13Fix rewinddir regression by cleaning up db_scanXavier Chantry
Commit 046003844739416ff6d168dd2dec76490adb0727 caused a regression when rereading the pkgcache after updating the on-disk databases. A rewinddir call was errantly removed. Instead of replacing the call to rewindir, clean up this whole mess. db_scan is used only once and with target == NULL so there was actually half the code of db_scan which was unused. This is gone now and replaced by a single new db_populate function. Dan: add_sorted ended up being 3x slower than one msort at the end, so I changed back to that. I also made one pointer variable const and merged this whole patch with my original fix for the rewinddir issue.

2008-05-13Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier
* remove obsolete and unused *_cmp helper functions like deppkg_cmp and _alpm_grp_cmp * new alpm_list_remove_str function, used 6 times in handle.c * remove _alpm_prov_cmp / _alpm_db_whatprovides and replace them by a more general alpm_find_pkg_satisfiers with a cleaner implementation. before: alpm_db_whatprovides(db, targ) after: alpm_find_pkg_satisfiers(alpm_db_getpkgcache(db), targ) * remove satisfycmp and replace alpm_list_find + satisfycmp usage by _alpm_find_dep_satisfiers. before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp) after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep) * remove _alpm_pkgname_pkg_cmp, which was used with alpm_list_remove, and use _alpm_pkg_find + alpm_list_remove with _alpm_pkg_cmp instead. This commit actually get rids of all complicated and asymmetric _cmp functions. I first thought these functions were worth it, be caused it allowed us to reuse list_find and list_remove. But this was at the detriment of the clarity and also the ease of use of these functions, dangerous because of their asymmetricity.
