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.

2014-08-04dep_graph_init: filter ignored packages by nameAndrew Gregory
Ignored packages are from the transaction remove list which consists of duplicated packages so a direct pointer comparison is not appropriate. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2014-06-24Update the question callbackOlivier Brunel
Much like with events, instead of using a bunch of void* arguments for all questions, we now send one pointer to an alpm_question_t union. This contains the type of question that was triggered. With this information, a question-specific struct can be accessed in order to get additional arguments. Signed-off-by: Olivier Brunel <jjk@jjacky.com> Signed-off-by: Allan McRae <allan@archlinux.org>

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.

2014-01-06deps.c: remove filtered_depend functionsAndrew Gregory
filtered_dep was duplicating an alpm_depend_t solely for the purpose of overriding its depmod and would effectively cause alpm_checkdeps to ignore ALPM_TRANS_FLAG_NODEPVERSION if the duplication failed. Manually overriding/restoring the depmod for the original depend removes the duplication as a point of failure and fixes a memory leak where the duplicated depend was not being properly freed.

2013-10-31sortbydeps: include local pkgs in dep graphAndrew Gregory
Detecting indirect dependencies by traversing a package's entire dependency tree is prohibitively slow for larger transactions. Instead add local packages to the dependency graph. This additionally requires delaying dependency ordering for sync operations so that removed packages may be excluded from dependency detection. tests/sync012.py was also updated to ensure that the dependency cycle was actually detected.

2013-10-31Expose alpm_pkg_should_ignoreAllan McRae
This function is useful for frontends to annotate package upgrades that will be ignored. Signed-off-by: Allan McRae <allan@archlinux.org>
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.

2013-06-26deps.c: check for indirect deps when orderingAndrew Gregory
On upgrades, indirect dependencies were not being detected if there was a dependency in between them that was not part of the transaction. For example, with the dependency chain: pkg1 -> pkg2 -> pkg3, if pkg1 and pkg3 are being upgraded but not pkg2 pacman would not order pkg1 and pkg3 properly. This was particularly problematic when replacements were involved because the replaced package(s) would be removed at the start of the transaction. If an install script required the replacer and lacked a direct dependency, it could fail. Fixes FS#32764. Partially fixes FS#23011.

2012-05-20fix -Wshadow warnings as reported by gcc 4.4.3Dave Reisner
Apparently gcc 4.7 has decided that -Wshadow warnings aren't worth reporting anymore even with the flag enabled. These were found on an Ubuntu 10.04 install. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-08Various tweaks to support building with excessive GCC warning flagsDan McGee
This fixes a bunch of small issues in order to enable a clean successful build with a crazy number of GCC warning flags. A lot of these changes are covered by -Wshadow, -Wformat-security, and -Wstrict-overflow=5. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-03-08Allow alpm_depend_t to have a descriptionDan McGee
This is the first step in parsing and handling optdepends. There is no behavior change introduced in this commit; however, depends that contain a ": " string will now be parsed as having a description and it will be stored in the depend structure. Later patches will utilize this new field as appropriate. This is heavily based on the work of Benedikt, who did something similar but introduced a new type for this rather than only a new field to the existing type.

2012-02-15Revert "Add -S --recursive operation"Dan McGee
This reverts commit f3fa77bcf1d792971c314f8c0de255866e89f3f3 along with making other necessary changes to fully back this (mis)feature out until we can do it correctly. The quick summary here is this was not implemented correctly; provides are not fully taken into account in this logic, and making that happen exposes a lot of other flaws in this code that are covered up later on in the dependency resolving process by several other pieces of convoluted and conditional logic. Tests have been adjusted accordingly. Some test EXISTS conditions have been removed as we already know the package is installed locally, and we also are checking the VERSION condition anyway. With these two related revert commits, we do have some changes in test pass/fail results: * upgrade078.py: does not pass, this is due to --recursive getting removed for -U/-S operations after this commit. * sync302.py: the version checks have been disabled, so this test continues to pass but has been scaled back in scope. * sync303.py: now passes, was failing before. * sync304.py: still failing, was failing before. * sync305.py: now passes, was failing before. * sync306.py: still passes, was passing before.

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.

2011-11-15Allow sync_prepare to work in certain cases without sync databasesDan McGee
When doing a bare -U operation on a local package that doesn't pull in any dependencies from the sync databases, we can get away with missing database files. This makes the check conditional on no sync targets found in the target list. This is not the prettiest code here so we have a bit of hackish behavior required to straighten both the behavior and the nonsensical error message out. Addresses FS#26899.

2011-09-27_alpm_splitdep: use malloc instead of callocDan McGee

2011-09-02Former transaction callback rename refactorDan McGee
Put all the callback stuff in alpm.h in one spot, and make the following renames for clarity with the new structure: ALPM_TRANS_EVT_* --> ALPM_EVENT_* ALPM_TRANS_CONV_* --> ALPM_QUESTION_* ALPM_TRANS_PROGRESS_* --> ALPM_PROGRESS_* alpm_option_get_convcb() --> alpm_option_get_questioncb() alpm_option_set_convcb() --> alpm_option_set_questioncb() Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-02Move all callbacks up to the handle levelDan McGee
This was just disgusting before, unnecessary to limit these to only usage in a transaction. Still a lot of more room for cleanup but we'll start by attaching them to the handle rather than the transaction we may or may not even want to use these callbacks. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-29Streamline alpm_splitdep() comparisonsDan McGee
This reduces from 5 to 3 the number of searches needed on the string looking for a comparison operator, since we can so a second quick comparison looking for '=' if we find '<' or '>'. It also makes every search doable with strchr() or memchr() rather than the slower strstr() method. In testing, only 10% of splitdep calls (~1600 / 16000) during an -Ss database load found a version comparison operator, so optimizing the not found path to be require less work makes sense. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-28_alpm_splitdep(): don't pass bogus length value to strndupDan McGee
If we fell through to the ALPM_DEP_MOD_ANY case, ptr would be NULL, and we would pass (0 - <str>), which is a rather large negative number or bogus positive number, depending on signed/unsigned. Just use strdup in the case where we don't have a ptr available. 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>
2011-08-18Convert resolvedep() to use _alpm_depcmp_literal()Dan McGee
The whole first loop is trying to check literals only, so teach it to do so. Also, reorder operations to make more sense by putting the strcmp() first in the literal loop, and using a very cheap name_hash check first in the second loop. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Add an _alpm_depcmp_literal() functionDan McGee
This omits the finding of matching provisions and only checks the package itself against the provided dep. Signed-off-by: Dan McGee <dan@archlinux.org>
