2011-04-24Rein in the complexity of the signature typeDan McGee
Given that we offer no transparency into the pmpgpsig_t type, we don't really need to expose it outside of the library, and at this point, we don't need it at all. Don't decode anything except when checking signatures. For packages/files not from a sync database, we now just read the signature file directly anyway. Also push the decoding logic down further into the check method so we don't need this hanging out in a less than ideal place. This will make it easier to conditionally compile things down the road.

2011-04-15Remove indirection on get_name and get_version operationsDan McGee
For a package to be loaded from any of our backends, these two fields are always required upfront. Due to this fact, we don't need them to be backend-specific operations and can just refer to the field directly. Additionally, our static (and thus private) cache package accessors had a NULL check on pkg before returning the relevant field. Eliminate this since they only way they are ever called is via the packages attached callback struct, which would have caused the NULL pointer dereference in the first place.

2011-03-23Allow PGP signature to be read from sync databaseDan McGee
Add a new field to the package struct to hold PGP information and instruct db_read to pick it up from the database. It is currently unused internally but this is the first step. Due to the fact that we store the PGP sig as binary data, we need to store both the data and the length so we have a small utility struct to assist us.

2011-03-20Style change: return(x) --> return xDan McGee
This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>

2011-02-04Read pkgcache into hashAllan McRae
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 McGee
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.

All functions that are limited to the local translation unit are declared static.

2010-12-29Detect undefined PATH_MAXAllan McRae
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 McGee
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 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.

2010-10-13Unify caching concerns in package accessorsDan McGee
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 McGee
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 Chantry
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 Gabor
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 Gabor

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.
