* libalpm: introduce a usage level for reposDave Reisner2013-09-04
| | | | | | | | | | | | | | | | 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.

* deps.c: check for indirect deps when orderingAndrew Gregory2013-06-26
| | | | | | | | | | | | | | | | | | | | 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.

* Various tweaks to support building with excessive GCC warning flagsDan McGee2012-04-08

* Allow alpm_depend_t to have a descriptionDan McGee2012-03-08
| | | | | | | | | | | | | | | 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.

| * Revert "Add -S --recursive operation"Dan McGee2012-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | include config.h via MakefilesDave Reisner2011-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Allow sync_prepare to work in certain cases without sync databasesDan McGee2011-11-15
| | | | | | | | | | | | | 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.

* Move all callbacks up to the handle levelDan McGee2011-09-02
| | | | | | | | | 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>
* Streamline alpm_splitdep() comparisonsDan McGee2011-08-29
| | | | | | | | | | | | | | 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>
* _alpm_splitdep(): don't pass bogus length value to strndupDan McGee2011-08-28
| | | | | | | | | 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>
* Be more robust when copying package dataDan McGee2011-08-19
| | | | | | | | | | | | | | | | 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>
* Convert resolvedep() to use _alpm_depcmp_literal()Dan McGee2011-08-18
| | | | | | | | | 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>
* Add an _alpm_depcmp_literal() functionDan McGee2011-08-18
| | | | | | | 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>
* Remove usages of alpm_list_next() in backendDan McGee2011-08-18
| | | | | | | Another function call that can be replaced by a single pointer dereference. Signed-off-by: Dan McGee <dan@archlinux.org>
* Parse conflicts/provides/replaces at database load timeDan McGee2011-08-15
| | | | | | | | | | | | | | | | | | | | | | 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.

* Add -S --recursive operationDan McGee2011-08-11
| | | | | | | | | | | | | | | | | | This closely matches what we had before for -R --recursive. Basically, when specifying a target (e.g., pacman), we can now recursively pull all dependencies, regardless of version specifiers and whether they are already satisfied in the local database. This could be used to update pacman on a system with an old glibc, for example, as both pacman and glibc would get pulled into the transaction. This is most useful with --needed to prevent needless reinstalls as described in the man page changes. The end goal of this change is to wire it into SyncFirst and have it be the default mode of operation there, but that belongs in a separate changeset. Signed-off-by: Dan McGee <dan@archlinux.org>

* Ensure handle is valid and pm_errno is reset when calling into APIDan McGee2011-06-14
| | | | | | | | | | | | | | | | | 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.
