2010-10-13Complete rework of package accessor logicDan McGee
Hopefully we've finally arrived at package handling nirvana, or at least this commit will get us a heck of a lot closer. The former method of getting the depends list for a package was the following: 1. call alpm_pkg_get_depends() 2. this method would check if the package came from the cache 3. if so, ensure our cache level is correct, otherwise call db_load 4. finally return the depends list Why did this suck? Because getting the depends list from the package shouldn't care about whether the package was loaded from a file, from the 'package cache', or some other system which we can't even use because the damn thing is so complicated. It should just return the depends list. So what does this commit change? It adds a pointer to a struct of function pointers to every package for all of these 'package operations' as I've decided to call them (I know, sounds completely straightforward, right?). So now when we call an alpm_pkg_get-* function, we don't do any of the cache logic or anything else there- we let the actual backend handle it by delegating all work to the method at pkg->ops->get_depends. Now that be_package has achieved equal status with be_files, we can treat packages from these completely different load points differently. We know a package loaded from a zip file will have all of its fields populated, so we can set up all its accessor functions to be direct accessors. On the other hand, the packages loaded from the local and sync DBs are not always fully-loaded, so their accessor functions are routed through the same logic as before. Net result? More code. However, this code now make it roughly 52 times easier to open the door to something like a read-only tar.gz database backend. Are you still reading? I'm impressed. Looking at the patch will probably be clearer than this long-winded explanation.

2010-10-13Allow local and sync db to be treated separatelyDan McGee
Implement this seemingly simple change in package.h: typedef enum _pmpkgfrom_t { - PKG_FROM_CACHE = 1, - PKG_FROM_FILE + PKG_FROM_FILE = 1, + PKG_FROM_LOCALDB, + PKG_FROM_SYNCDB } pmpkgfrom_t; which requires flushing out several assumptions from around the codebase with regards to usage of the PKG_FROM_CACHE value. Make some changes where required to allow the switch, and now the correct value should be set (via a crude hack) depending on whether a package was loaded as an entry in a local db or a sync db. This patch underwent some big rebasing from Allan and Dan. Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2009-10-11int typing: s/unsigned short/int/ in libalpmDan McGee
After our recent screwup with size_t and ssize_t in the download code, I found the `-Wsign-conversion` flag to GCC to see if we were doing anything else boneheaded. I didn't find anything quite as bad, but we did have some goofups- most of our public unsigned methods would return -1 on error, which is a bit odd in an unsigned context.

2009-06-07Introduce _alpm_pkg_free_trans()Nagy Gabor
The main purpose of this function to make our code more readable. It frees transaction specific fields of pmpkg_t. (It is used when a package is removed from the target list.) Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
2009-04-11Remove pmsyncpkg_tNagy Gabor
pmsyncpkg_t data sructure was removed: 1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target packages come from sync repos, so we can use this field without any problems. Upgrade transaction also uses this field to store this info.) 2. pmsyncpkg_t.removes was moved to pmpkg_t.removes. This step requires careful programming, because we don't duplicate packages when we add them to trans->packages. So we modify sync pkgcache when we add this transaction-only info to our package. Hence it is important to free this list when we remove any package from the target list (remove_unresolvable, remove_conflicts, trans_free), otherwise this could confuse the new sync transactions (with non-pacman GUI). Overall, our code became ~100 line shorter, and we can call our helper functions directly on trans->packages in sync.c, we don't need to maintain parallel package lists.

2008-06-04Use correct C type for file sizesDan McGee
We have been using unsigned long as a file size type for a while, which works but isn't quite correct and could easily break. Worse was probably our use of int in the download callback functions, which could be restrictive for packages > 2GB in size. Switch all file size variables to use off_t, which is the preferred type for file sizes. Note that at least on Linux, all applications compiled against libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS is defined to be 64 or there will be some weird issues that crop up.

2008-05-14Remove wrapper call around versioncmpDan McGee
Actually, just rename _alpm_versioncmp to alpm_pkg_vercmp and get rid of the need for a wrapper since it did nothing anyway. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-05-13Simplify _alpm_pkg_new()Dan McGee
Any real call of this function doesn't specify a name or version ahead of time, so just kill that functionality off. Now to remove those dummy packages... Signed-off-by: Dan McGee <dan@archlinux.org>
2008-05-13Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier
* 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.

2008-05-11Refactor pkg_load/parse_descfile into a new backend fileDan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-04-26Completely rework delta algorithmChantry Xavier
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.

2008-02-06libalpm/package.c : add _alpm_pkgname_pkg_cmp function.Nagy Gabor
_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. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

2008-01-11Fix library interfaceDan McGee

2008-01-11Use dynamic string allocation in package structuresDan McGee
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.

2007-09-28Support for localized times in metadataAaron Griffin
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. Old existing packages with the text format are still supported, but this is deprecated. In the case of removal of text time support, this code will fail gracefully, returning the start of the epoch for broken packages. Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
2007-09-28Add 'full' parameter to alpm_pkg_loadDan McGee
In most cases, we want to fully scan a package when we load it, which serves as a integrity verification check. However, there are times when it is only desired to read the metadata and nothing else, so allow the caller of pkg_load to choose the behavior they need. This pays big dividends in speeding up pacman cache cleaning functionality. Old (729 packages): real 1m43.717s user 1m20.785s sys 0m2.993s New (729 packages): real 0m25.607s user 0m19.389s sys 0m0.543s Signed-off-by: Dan McGee <dan@archlinux.org>
2007-09-28Remove package name dependency from libalpmDan McGee
Previously, package names must match a specified scheme or they will cause pacman add operations to fail. This is not a very intelligent or necessary way to act, so remove the dependency on the name of the package to be installed and read all relevant information from the metadata instead. This does have one causality to be addressed later- pacman cache cleaning functionality, which has never been phenomenal, just lost most capability. Signed-off-by: Dan McGee <dan@archlinux.org>

2007-08-14package.h: implement origin_data union in pmpkg_t structDan McGee
We were using a void *data element in pmpkg_t before, which is unsafe by its nature of being untyped. Reimplement data as origin_data being a union that can hold either a path to a package file or a pointer to a cache database, and make the other necesary updates in the code to reflect this. See package.h for details. Signed-off-by: Dan McGee <dan@archlinux.org>

2007-03-03Big commit this time:Aaron Griffin
* Moved entirely to alpm_pkg_get_* accessors, to read data on demand * Mostly removed the INFRQ_ parameters from outside the be_files backend (making the backend more extensible in the long run) * packages created from _alpm_db_scan now have the db and origin set (making accessors actually work for these packages) * removed _alpm_db_ensure_pkgcache * totally revamped the _alpm_checkconflicts function, making it cleaner and easier to read (and thus fix in the long run) - maintainable code ftw NOTE: feel free to rename the functions... I couldn't think of anything better * removed an extra loop in sync.c:find_replacements - no sense in looping over an entire DB while strcmp'ing the name, when we have get_pkgfromcache Other: * package struct "license" -> "licenses" * Created _alpm_sync_find (duplicate code in some places, find_pkginsync * Minor const correctness changes along the way * fixed a couple extra '/' pathing issues (non-issues really) * removed a duplicate pkg_cmp function

2007-02-17* A whole mess of backup changesAaron Griffin
- the code should be clearer, more organized, commented, and have worthwhile variable names now - proactive backup=()s now work. That is, adding a file to a backup array does what it should on the upgrade to that package, no longer forcing you to wait a full upgrade cycle for it to take effect * ldconfig was being run twice on an upgrade operation - fixed * fixed another pm_fprintf/printf output corruption with the progress bars * refactored some duplicate code for adjusting 'requiredby' lists * Added config.rpath to .cvsignore
2007-02-13Removed desc_localized for the time being. We don't have localizedAaron Griffin
descriptions, nor do we actually build them with the newest makepkg. The actual implementation in here seems like it could be done better, and it soaks a large amount of CPU time according to profilers.
