* Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier2008-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * remove obsolete and unused *_cmp helper functions like deppkg_cmp and _alpm_grp_cmp * new alpm_list_remove_str function, used 6 times in handle.c * remove _alpm_prov_cmp / _alpm_db_whatprovides and replace them by a more general alpm_find_pkg_satisfiers with a cleaner implementation. before: alpm_db_whatprovides(db, targ) after: alpm_find_pkg_satisfiers(alpm_db_getpkgcache(db), targ) * remove satisfycmp and replace alpm_list_find + satisfycmp usage by _alpm_find_dep_satisfiers. before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp) after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep) * remove _alpm_pkgname_pkg_cmp, which was used with alpm_list_remove, and use _alpm_pkg_find + alpm_list_remove with _alpm_pkg_cmp instead. This commit actually get rids of all complicated and asymmetric _cmp functions. I first thought these functions were worth it, be caused it allowed us to reuse list_find and list_remove. But this was at the detriment of the clarity and also the ease of use of these functions, dangerous because of their asymmetricity.

* Refactor pkg_load/parse_descfile into a new backend fileDan McGee2008-05-11
| | | | | | | | | | alpm_pkg_load() and parse_descfile() are specific to getting information from package files, just as other code is specific to getting information into or out of a package database. Move this code out of package.c, which should eventually only contain operators on the pmpkg_t struct that do not depend at all on where the data came from.

* get_filename : use the FILENAME db field only.Chantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | Reference : FS#9547. The get_filename function first tries to get the filename field from the database, and if it doesn't find it, it tries to guess it based on the name, version and arch. This field was introduced in 3.0, but there are still many old entries in the official databases without it. So the databases need to be regenerated first before this patch can be applied. There is a second problem with the delta code, which needs the filename for locally installed packages too, but this field is not present in the local db. So the delta code needs to be fixed first.

* Completely rework delta algorithmChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | Using the graph structures that Nagy set up for dependency sorting, we now do a similar process for deltas. Load up all of the deltas into a graph object on which we can then apply Dijkstra's algorithm, using the new weight field of graph struct. We initialize the nodes weight using the base files that we can use in our filecache (both filename and md5sum must match). The algorithm then picks the best path among those that can be resolved. Note that this algorithm has a few advantages over the old one: 1. It is completely file agnostic. These delta chains do not have to consist of package files- this could be adopted to do delta-fied DBs. 2. It does not use the local_db anymore, or even care if a package or file is currently installed. Instead, it only looks in the filecache for files and packages that match delta chain entries.

| | | | | | | | | With the addition of the archive_fgets() function, we can now skip the temp file usage in pkg_load/parse_descfile that was not needed. This has a nice benefit of probably being both faster, reducing code, and getting rid of "expensive" file operations. Signed-off-by: Dan McGee <dan@archlinux.org>

* | libalpm: clean up of md5sum functions.Chantry Xavier2008-02-27
| | | | | | | | | | | | | | | | | | test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum, and only used once, so not very useful. I removed them. Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated, so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | This is the first step of fixing FS#9547. This should not break any existing code that may rely on this function behaving the way it did, and should be good for inclusion in a maint release.

* | libalpm/package.c : add _alpm_pkgname_pkg_cmp function.Nagy Gabor2008-02-06
| | | | | | | | | | | | | | | | | | | | | | _alpm_pkgname_pkg_cmp(pkgname, pkg) returns true iff pkg's name is pkgname. This is useful if you want to remove a package from pmpkg_t* list, and you want to search for package name. This allows cleaning the -Ru code a bit, by removing the need of a dummy pkg.

* | Move the deptest code from frontend to backend.Chantry Xavier2008-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The deptest code (pacman -T) used by makepkg was mostly in the frontend. There were 2 drawbacks: 1) the public splitdep function returns a pmdepend_t struct, but the _alpm_dep_free function for freeing it is private. So there was a memleak. 2) there is a helper in the backend (satisfycmp in deps.c) which makes this function much easier. So this adds a new public alpm_deptest in libalpm/deps.c, which cleans pacman_deptest in pacman/deptest.c a lot. Besides, alpm_splitdep was made private, because the frontend no longer requires it, and _alpm_dep_free is also private. Finally the deptest001 pactest was extended.

* | Add functions to manipulate pmdepend_t objectsDan McGee2008-01-11
| | | | | | | | | | | | | | | | | | | | | | We didn't have a free function before, causing some memory leaks. We also need a dup function now that strings are not in the structure but are dynamically allocated. Also adapt pmdepmissing_t to use a pointer to a depend struct instead of an inclusive one so we can use the functions we created here. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Use dynamic string allocation in package structuresDan McGee2008-01-11
|/ | | | | | | | | | | | | | This also affects all structures with static strings, such as depmiss, conflict, etc. This should help a lot with memory usage, and hopefully make things a bit more "idiot proof". Currently our pactest pass/fail rate is identical before and after this patch. This is not to say it is a perfect patch- I have yet to pull valgrind out. However, this should be quite safe to use in all situations from here on out, and we can start plugging the memleaks.

| | | | | | | | | | | | | | This is something pacman can do on its own straight from the archive, and we will reduce the chance of problems occurring becuase of inproper FILELIST generation as we have had in the past with special characters in filenames. Once we remove it from makepkg. we can remove any usage of it from all of our other tools, including pacman, pactest, and contrib/ utilities. Note that removing it from pacman uncovered a few other bugs anyway, so this was probably a good move. Signed-off-by: Dan McGee <dan@archlinux.org>
* Check for errors on descfile extractionDan McGee2007-12-16
| | | | | | | | | | | | | If /tmp was full during the early stages of package extraction, we were unable to extract the package description file with the call to archive_read_data_into_fd(archive, fd) becuase we never checked the return code.

* Improve changelog handling through addition of open/read/close functionsDan McGee2007-12-09
| | | | | | | | | | | | | | | | | | | | | | | Thanks to Allan for inspiring all this work on what was one little TODO item in the codebase. :) Change changelog handling so we can now dump a changelog from both installed packages and package files (fixes FS#7371). We do this by moving all of the machinery to the backend where it should have been in the first place. The changelog reading is now done through a open/read/close interface similar to the fopen/fread/fclose functions (can you guess how it is done?). It is buffered by the frontend, so programs using the library can read as much or as little as they want at a time. Unfortunately, I could not implement a changelog_feof function due to some shortcomings of libarchive. However, I left the stub code in there, commented out, in case it becomes possible later or anyone wants to take a stab at it.

| | | | | | | | | | So I spent a good 4 hours tracking a bug down tonight due to alpm_list_copy_data not actually doing what I expected to do. We can't find the size of an object we don't know the type of, so rewrite it so we pass in the size explicitly. This was making _alpm_pkg_dup fail and causing all sorts of other issues.

* Move alpm_splitdep usage to db_readDan McGee2007-11-14
| | | | | | | | | | | | | Holy inefficient batman! For a pacman -Qt operation (when we are using compute_requiredby and not database entries), splitdep was being called ~1.3 million times on my local database. By splitting when we read the DB, we drop this number to around 1700 and save a LOT of time in doing so (a 5x increase in pacman -Qt speed here). Note that the depends alpm_list_t in the package struct is no longer a string list, but a list of pmdepent_t objects. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove REQUIREDBY usage from libalpmDan McGee2007-11-14
| | | | | | | | | | | | Instead of using the often-busted REQUIREDBY entries in the pacman database, compute them each time they are required. This should help many things: 1. Simplify the codebase 2. Prevent future database corruption 3. Ensure when we do use requiredby, it is always correct 4.

* Fix some issues with localized dates/epoch usageDan McGee2007-11-08
| | | | | | | | | | | | | Commit 47622eef4dd8fd86a0aa0e3ebdb7b33f7c9d6804 introduced localized times in the metadata by way of storing the UNIX epoch value instead of a hard coded date string. However, it missed a few things: * If we weren't in the C/POSIX/en_US locale, the date parsing would fail as it tried to use the abbreviations of the locale being used. Fix this by switching the LC_TIME value before we parse a date. * We used ctime to print the date value, which is always the C locale string. Instead, use strftime to print a localized date string.

* libalpm: introduce MALLOC and CALLOC macrosDan McGee2007-10-29
| | | | | | | | | | | | | | | | | These macros take the place of the common 4 or 5 line blocks of code we had in most places that called malloc or calloc. This should reduce some code duplication and make memory allocation more standard in libalpm. Highlights: * Note that the MALLOC macro actually uses calloc, this is just for safety so that memory is initialized to 0. This can be easily changed in one place. * One malloc call was completely eliminated- it made more sense to do it on the stack. * The use of RET_ERR in public functions (mainly the alpm_*_new functions) was standardized, this makes sense so pm_errno is set.

* libalpm/package.c : fix requiredby with multiple providers.Chantry Xavier2007-10-18
| | | | | | | | | | | | | | | | | | The code didn't match the following comment : "A depends on B through n depends <=> A listed in B's requiredby n times" It stopped at n=1 with a break. I was surprised to see this case happens in real, that's how I noticed the bug: wine depends on both freeglut and glut, while freeglut provides glut. So when installing wine, the update_depends function listed wine twice in freeglut's requiredby. But the compute_requiredby function (used when installing freeglut, and used by testdb) listed wine only once in freeglut's requiredby. That made testdb unhappy.

| | | | | | | | | | | | Packages and DBs now support using the UNIX epoch (seconds since Jan 1, 1970) for use in builddate and installdate. This will only affect newly built packages.

| | | | | | | | | | | | | | | | | | | In most cases, we want to fully scan a package when we load it, which serves as a integrity verification check.

* Remove package name dependency from libalpmDan McGee2007-09-28
| | | | | | | | | | | | Previously, package names must match a specified scheme or they will cause pacman add operations to fail.
