2018-05-14Remove all modelines from the projectEli Schwartz
Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2016-10-22Represent bitfields as ints, not enumsIvy Foster
Many bitfield variables are declared to be enums, because they are generated using bitwise operations on enums such. However, their actual values aren't necessary members of their parent enum, so declaring them 'int' is more accurate.

2016-10-22Add ALPM_ERR_OK to _alpm_errno_tIvy Foster
This allows functions which return an _alpm_errno_t to always return a genuine _alpm_errno_t for consistency, even in cases where there are no errors. Since ALPM_ERR_OK = 0, their callers can still simply check 'err = some_fn(); if (!err) { ... }'. Signed-off-by: Ivy Foster <ivy.foster@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2015-01-02initialize pointers passed to _alpm_pkg_dupAndrew Gregory
_alpm_pkg_dup leaves the destination pointer unaltered in case of fatal errors, so when commits 2f0ca00e and be4198b3 freed the pointer, they fixed a memory leak on non-fatal errors by replacing it with a segmentation fault on fatal errors.

Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand.

2013-09-04libalpm: introduce a usage level for reposDave Reisner
This defines a level of interest a user has in a repository. These are described by the bitmask flags in the alpm_db_usage_t enum: ALPM_DB_USAGE_SEARCH: repo is valid for searching ALPM_DB_USAGE_INSTALL: repo is valid for installs (e.g. -S pkg) ALPM_DB_USAGE_UPGRADE: repo is valid for sysupgrades ALPM_DB_USAGE_ALL: all of the above are valid Explicitly listing the contents of a repo will always be valid, and the repo will always be refreshed appropriately on sync operations.

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.

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.
