2011-02-04Read pkgcache into hashAllan McRae1-1/+1
Read the package information for sync/local databases into a pmpkghash_t structure. Provide a alpm_db_get_pkgcache_list() method that returns the list from the hash object. Most usages of alpm_db_get_pkgcache are converted to this at this stage for ease of implementation. Review whether these are better accessing the hash table directly at a later stage.

2011-01-21Remove epoch as an independent fieldDan McGee1-20/+0
Instead, go the same route we have always taken with version-release in libalpm and treat it all as one piece of information. Makepkg is the only script that knows about epoch as a distinct value; from there on out we will parse out the components as necessary. This makes the code a lot simpler as far as epoch handling goes. The downside here is that we are tossing some compatibility to the wind; packages using force will have to be rebuilt with an incremented epoch to keep their special status.

2010-12-30Declare all local functions staticAllan McRae1-26/+26
All functions that are limited to the local translation unit are declared static. This exposed that the _pkg_get_deltas declaration in be_local.c was being satified by the function in packages.c which when declared static caused linker failures.

2010-12-29Detect undefined PATH_MAXAllan McRae1-1/+0
POSIX does not require PATH_MAX be defined when there is not actual limit to its value. This affects HURD based systems. Work around this by defining PATH_MAX to 4096 (as on Linux) when this is not defined. Also, clean up inclusions of limits.h and remove autoconf check for this header as we do not use macro shields for its inclusion anyway.

2010-12-14Used hashed package name in _alpm_pkg_findDan McGee1-2/+13
This results in huge gains to a lot of our codepaths since this is the most frequent method of random access to packages in a list. The gains are seen in both profiling and real life. $ pacman -Sii zvbi real: 0.41 sec -> 0.32 sec strcmp: 16,669,760 calls -> 473,942 calls _alpm_pkg_find: 52.73% -> 26.31% of time $ pacman -Su (no upgrades found) real: 0.40 sec -> 0.50 sec strcmp: 19,497,226 calls -> 524,097 calls _alpm_pkg_find: 52.36% -> 26.15% of time There is some minor risk with this patch, but most of it should be avoided by falling back to strcmp() if we encounter a package with a '0' hash value (which we should not via any existing code path). We also do a strcmp once hash values match to ensure against hash collisions. The risk left is that a package name is modified once it was originally set, but the hash value is left alone. That would probably result in a lot of other problems anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-10-13Complete rework of package accessor logicDan McGee1-81/+93
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 McGee1-26/+27
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>
2010-10-13Unify caching concerns in package accessorsDan McGee1-181/+30
Move almost all of the caching related stuff into a single #define (which should maybe even just be a static function) so we don't duplicate logic all over the place. This also makes the code a heck of a lot shorter and means further changes to this stuff don't have to touch each and every getter function. Signed-off-by: Dan McGee <dan@archlinux.org>

2009-10-24Reduce unnecessary get_name() function callsDan McGee1-3/+3
alpm_pkg_get_name() gives us little benefit in backend code besides a NULL check on the package passed in; we could do that ourself if necessary. By changing to direct references in the cases where we are sure we have a valid package, we save a function call each time we need a package name. This function can't be inlined because it is externally accessible. This cuts the calls to get_name() from 1.3 million times in a pacman -Qu operation to around 2400.

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.

2009-09-08Remove transaction typeXavier Chantry1-7/+0
This basically started with this change : /* Transaction */ struct __pmtrans_t { - pmtranstype_t type; pmtransflag_t flags; pmtransstate_t state; - alpm_list_t *packages; /* list of (pmpkg_t *) */ + alpm_list_t *add; /* list of (pmpkg_t *) */ + alpm_list_t *remove; /* list of (pmpkg_t *) */ And then I have to modify all the code accordingly.
2009-09-08Use sync.c for upgrade transaction prepare and commitNagy Gabor1-1/+10
This patch utilizes the power of sync.c to fix FS#3492 and FS#5798. Now an upgrade transaction is just a sync transaction internally (in alpm), so all sync features are available with -U as well: * conflict resolving * sync dependencies from sync repos * remove unresolvable targets See http://www.archlinux.org/pipermail/pacman-dev/2009-June/008725.html for the concept. We use "mixed" target list, where PKG_FROM_FILE origin indicates local package file, PKG_FROM_CACHE indicates sync package. The front-end can add only one type of packages (depending on transaction type) atm, but if alpm resolves dependencies for -U, we may get a real mixed trans->packages list. _alpm_pkg_free_trans() was modified so that it can handle both target types _alpm_add_prepare() was removed, we use _alpm_sync_prepare() instead _alpm_add_commit() was renamed to _alpm_upgrade_targets() sync.c (and deps.c) was modified slightly to handle mixed target lists, the modifications are straightforward. There is one notable change here: We don't create new upgrade trans in sync.c, we replace the pkgcache entries with the loaded package files in the target list (this is a bit hackish) and call _alpm_upgrade_targets(). This implies a TODO (pkg->origin_data.db is not accessible anymore), but it doesn't hurt anything with pacman front-end, so it will be fixed later (otherwise this patch would be huge). I updated the documentation of -U and I added a new pactest, upgrade090.py, to test the syncdeps feature of -U.

2009-06-07Introduce _alpm_pkg_free_trans()Nagy Gabor1-0/+13

2009-04-11Remove pmsyncpkg_tNagy Gabor1-0/+8
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.

* Change the return values to be more informative. It was previously boolean, only indicating if a sync package was newer than a local package. Now it is a simple wrapper to vercmp, handling the force flag. * Remove the verbose output from _alpm_pkg_compare_versions. The "force" message is not so useful. The "package : local (v1) is newer than repo (v2)" message can be moved to -Su operation. For the -S operation, it is better to have something like : "downgrading package from v1 to v2" * Don't display the "up to date -- skipping" and "up to date -- reinstalling" messages, when the local version is newer than the sync one. * Fix the behavior of --needed option to not skip a target when the local version is newer, and clarify its description. * Add a new alpm_pkg_has_force function This allows us to access the pkg->force field like any other package fields.

2008-06-04Use correct C type for file sizesDan McGee1-2/+2
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.

2008-05-30Fix versioncmp regression after updateDan McGee1-9/+27
Commit 84283672853350a84d2a71b72dc06e180cad1587 introduced the regression, and a previous commit introduced the vercmptest.sh test script to track down these issues. This commit solves the problem by removing the previous attempt at locating the pkgrel portions and replacing it with something that performs the correct logic. While tracking down everything I needed to, I also found a mistake in one of the pactests which is fixed here as well as increased the functionality and verbosity of the vercmptest script to both print out each test it is running as well as automatically run the mirror of each test case.

2008-04-26get_filename : use the FILENAME db field only.Chantry Xavier1-13/+0
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.
