2011-07-05signing: move to new signing verification and return schemeDan McGee1-8/+8
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 McRae1-9/+9
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 McRae1-5/+5
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 McGee1-17/+0
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 McGee1-23/+26
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 McGee1-13/+0
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 McGee1-2/+3
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.

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-4/+16
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 McGee1-14/+0
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>
2011-06-14Add a helper method for retrieving the DB signature pathDan McGee1-0/+14
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>
2011-06-14Switch all logging to use handle directlyDan McGee1-23/+19
This is the last user of our global handle object. Once again the diff is large but the functional changes are not. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-14Move pm_errno onto the handleDan McGee1-38/+37
This involves some serious changes and a very messy diff, unfortunately. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-09Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee1-1/+1
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>
2011-06-07New signatures for alpm initialize and releaseDan McGee1-1/+1
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 McGee1-60/+0
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>
2011-05-05Improve database server APIDan McGee1-16/+80
Currently we have one call that has all sorts of crazy behavior and doesn't make a whole lot of sense. Go from one method to the normal four methods we have for all of our other lists we use in the library to make it a lot easier for a frontend to manipulate server lists.

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.

2011-03-23Added gpg verification options per repo to the config file.Xavier Chantry1-0/+18
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.
