2012-02-06ALPM API adjustments for sanity and consistencyDan McGee
This makes several small adjustments to our exposed method names, and in one case, parameters. The justification here is to make methods less odd in their naming convention. If a method takes an alpm_db_t argument, the method should be named 'alpm_db_*', but perhaps more importantly, if it doesn't take a database as the first parameter, it should not. Summary of changes: alpm_db_register_sync -> alpm_register_syncdb alpm_db_unregister_all -> alpm_unregister_all_syncdbs alpm_option_get_localdb -> aplpm_get_localdb alpm_option_get_syncdbs -> aplpm_get_syncdbs alpm_db_readgroup -> alpm_db_get_group alpm_db_set_pkgreason -> alpm_pkg_set_reason All methods keep the same argument list except for alpm_pkg_set_reason; there we drop the 'handle' argument as it can be retrieved from the passed in package object.

2011-12-21include config.h via MakefilesDave Reisner
Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

2011-09-20Access db->pkgcache directly in db_free_pkgcache()Dan McGee
We shouldn't be going through the accessor that does a bunch of unnecessary legwork, including potentially loading the pkgcache right before we free it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-18Remove const specifier from changelog_read() void parameterDan McGee
This shouldn't really be declared with const, and causes a compile error when -Wcast-qual is used. Remove the const specifier from the function specification and all implementations. Also fix one other trivial -Wcast-qual warning in _alpm_db_cmp(). Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-19Remove alpm_option_get_* usage from backendDan McGee
These are all available directly on the handle without indirection. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-19Be more robust when copying package dataDan McGee
This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Remove use of no-op accessor functions in libraryDan McGee
The functions alpm_db_get_name(), alpm_pkg_get_name(), and alpm_pkg_get_version() are not necessary at all, so remove the calling and indirection when used in the backend, which makes things slightly more efficient and reduces code size. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Enhance and utilize database status flagsDan McGee
* Move is_local standalone field to status enum * Create VALID/INVALID flag pair * Create EXISTS/MISSING flag pair With these additional fields, we can be more intelligent with database loading and messages to the user. We now only warn once if a sync database does not exist and do not continue to try to load it once we have marked it as missing. The reason for the flags existing in pairs is so the unknown case can be represented. There should never be a time when both flags in the same group are true, but if they are both false, it represents the unknown case. Care is taken to always manipulate both flags at the same time. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Only check necessary signatures and checksumsDan McGee
The precedence goes as follows: signature > sha256sum > md5sum Add some logic and helper methods to check what we have available when loading a package, and then only check what is necessary to verify the package. This should speed up sync database verifies as we no longer will be doing both a checksum and a signature validation. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Parse conflicts/provides/replaces at database load timeDan McGee
We did this with depends way back in commit c244cfecf654d3 in 2007. We can do it with these fields as well. Of note is the inclusion of provides even though only '=' is supported- we'll parse other things, but no guarantees are given as to behavior, which is more or less similar to before since we only looked for the equals sign. Also of note is the non-inclusion of optdepends; this will likely be resolved down the road. The biggest benefactors of this change will be the resolving code that formerly had to parse and reparse several of these fields; it only happens once now at load time. This does lead to the disadvantage that we will now always be parsing this information up front even if we never need it in the split form, but as these are uncommon fields and our parser is quite efficient it shouldn't be a big concern.

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>
2011-07-14Make 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>
2011-07-05signing: 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.

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>

2011-06-27Remove setter for DB signature levelDan McGee
This should have been removed with commit db3b86e7f34f but was erroniously left behind. Signed-off-by: Dan McGee <dan@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>
2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-14Remove alpm_db_get_url()Dan McGee
This method is old, it doesn't adequately check for a NULL server list, and can easily be done using better API method we provide these days. All former users of this method can get similar results by calling alpm_db_get_servers() and using the data from the returned server list. 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>

2011-06-09Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee

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>

2011-06-03Remove ALPM_LOG_FUNC macroDan McGee
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. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>
