2011-02-11Avoid a memmove by advancing value pointerDan McGee1-0/+1
In packages, our description file contains: key = value is here type entries, and we passed "key " and " value is here" to our strtrim function, causing us to always memmove the value portion to remove the space. Since this is a throwaway buffer, do the advancing on our own before trimming to save the need to shift memory around; "value is here" will now be passed and strtrim will be responsible for trailing whitespace.

2011-02-08Skip diskspace checking for symlinks and directories in all casesDan McGee2-42/+44
We did this in some but not all cases, assuming the 0 value coming out of libarchive would not be a problem. However, this does not work for "fake" filesystems such as rpc_pipefs, which reports a free block and total block count of zero. Fix this by not ever counting symlinks or directories, and adding a note explaining that if we someday do count directories, their size needs to be attributed to the proper place. This patch also includes a few cleanups/performance tweaks- avoid calling strlen() on the mountpoint directory string as much by storing this size in our mountpoint struct, and push the snprintf() call up to the calculate functions since we were already doing it here in the remove case.

2011-02-07Refactor out common code in pkghash add functionsPang Yan Han1-30/+15
The overlapping code in _alpm_pkghash_add() and _alpm_pkghash_add_sorted() are now in a new static function pkghash_add_pkg(). This function has a third flag parameter which determines whether the package should be added in sorted order.

2011-02-07Handle null pkgcache for local/sync db_populate()Pang Yan Han2-1/+11
In sync_db_populate() and local_db_populate(), a NULL db->pkgcache is not caught, allowing the functions to continue instead of exiting. A later alpm_list_msort() call which uses alpm_list_nth() will thus traverse invalid pointers in a non-existent db->pkgcache->list. pm_errno is set to PM_ERR_MEMORY as _alpm_pkghash_create() will only return NULL when we run out of memory / exceed max hash table size. The local/sync db_populate() functions are also exited. Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-02-06Remove redundant _alpm_strtrim() in be_local.cPang Yan Han1-9/+9
When reading the "desc" file in _alpm_local_db_read(), some strings are trimmed and checked for length > 0 before their use/duplication subsequently. They are then trimmed again when there is no need to. The following code snippet should illustrate it clearly: while(fgets(line, sizeof(line), fp) && strlen(_alpm_strtrim(line))) { char *linedup; STRDUP(linedup, _alpm_strtrim(line), goto error); info->groups = alpm_list_add(info->groups, linedup); } This patch removes the redundant _alpm_strtrim() calls in _alpm_local_db_read() such as the one inside the STRDUP shown above.

2011-02-04Ensure found files are actually filesDan McGee2-3/+4
We located files in a few places but didn't check if they were files or directories. Ensure they are actually files using stat() and S_ISREG(); this showed itself when trying to download to the directory name itself in FS#22645. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Improve pkghash_remove algorithmDan McGee1-19/+43
Rather than potentially move every item to the next NULL, attempt to move at most one item at a time by iterating backwards from the NULL location in the hash array. If we move an item, we repeat the process on the now shorter "chain" until no more items need moving. Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2011-02-04Add new alpm_list_remove_item() functionDan McGee2-33/+54
This takes in the list and a list item, and does the pointer dance necessary to remove it from the list regardless of whether it is first, last, or somewhere in the middle. It is useful for callers that already know what item needs to be removed and have a pointer to it rather than doing a search by data that the plain alpm_list_remove() does. Refactor alpm_list_remove() to use this function as well. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Actually remove packages from pkghash on removalAllan McRae3-10/+31

2011-02-04Slightly more efficient rehash size selectionAllan McRae1-2/+4
While probably still not optimal in terms of everyday usage in pacman, this reduces the absolute size increase to "more reasonable" levels. For databases greater than 5000 in size, the minimum size increase is used which is still on the order of a 10% increase. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-02-04Error handling for maximum database sizeAllan McRae1-0/+12
Check that the requested size of a pkghash is not beyond the maximum prime. Also check for successful creation of a new hash before rehashing. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-02-04Change default sync hash table sizing to 66% fullDan McGee1-2/+2
Since the sync database never changes size once we initialize it, we allow it to be filled a bit more. This reduces the overall memory footprint needed by the hash table. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Implement a quick and dirty rehash functionDan McGee1-11/+16
This allows us to get through the rehash required by smoke001 and pass all pactests. It is by no means the best or most efficient implementation but it does do the job. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Read pkgcache into hashAllan McRae10-38/+80
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. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-02-04Get estimated package count when populating databasesDan McGee2-2/+70
This works for both local and sync databases in slightly different ways. For the local database, we can use the directory hard link count on the local/ folder. For sync databases, we use the archive size coupled with some computed average per-package sizes to determine an estimate. This is currently a dead assignment once calculated, but could be used to set the initial size of a hash table.

Noted in FS#22697. When I factored out _alpm_parsedate() into a common function, I didn't move the <locale.h> include properly, causing a build failure when NLS is disabled and this header isn't automatically included everywhere. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-31alpm/depcmp: new NODEPVERSION flagXavier Chantry3-9/+37
This flag allows to disable version checking in dependency resolving code. depcmp_tolerant respects the NODEPVERSION flag but we still keep the original strict depcmp. The idea is to reduce the impact of the NODEPVERSION flag by using it in fewer places. I replaced almost all depcmp calls by depcmp_tolerant in deps.c (except in the public find_satisfier used by deptest / pacman -T), but I kept depcmp in sync.c and conflict.c Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-01-29alpm: drop old target interfacesXavier Chantry4-282/+0
It's likely that these interfaces will break sooner or later, now that pacman no longer uses them. So better force the two people who use them to migrate their code to the new add_pkg/remove_pkg interface, which is very easy anyway. Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com>
2011-01-29alpm: deprecate old interfaceXavier Chantry1-5/+5

2011-01-29alpm: new alpm_add_pkg interfaceXavier Chantry2-0/+66
This new function is meant to deprecate all existing sync/add target functions : int alpm_sync_target(char *target); int alpm_sync_dbtarget(char *db, char *target); int alpm_add_target(char *target); Rather than dropping these 3 interfaces, it might be better to rewrite them using alpm_add_pkg for now.

2011-01-29alpm/dep: add alpm_find_dbs_satisfierXavier Chantry2-0/+23
This is a public interface for resolvedep. It looks nicer to expose it this way rather than through sync_target.

2011-01-29Add interactive provider selectionXavier Chantry2-3/+36
If there are multiple providers in one db, pacman used to just stop at the first one (both during dependency resolution or for pacman -S 'provision' which uses the same code). This adds a new conversation callback so that the user can choose which provider to install. By default (user press enter or --noconfirm), the first provider is still chosen, so for example the behavior of sync402 and 403 is preserved. But at least the user now has the possibility to make the right choice in a manual run. If one of the provider is already installed, it is picked for reinstall/upgrade, so that provision 002/003 pactest now pass. $ pacman -S community/smtp-server :: There are 3 providers available for smtp-server: 1) courier-mta 2) esmtp 3) exim Which one do you want to install?

2011-01-21Remove epoch as an independent fieldDan McGee6-55/+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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-21Allow version comparison to contain epoch specifierDan McGee1-40/+117
Adapting from RPM, follow the [epoch:]version[-release] syntax. We can also borrow some of their parsing code for our purposes (thanks!).

2011-01-21Add a likely_pkg hint argument to sync_db_readDan McGee1-10/+16
In most (all?) cases, we will process all files for a given sync database entry sequentially. The code currently does an _alpm_pkg_find() for every file in the database, but we had the "current" package readily available. Shift some local variables around a bit to expose this to sync_db_read() and use it if the package is the correct one. On my system, this cuts calls to _alpm_pkg_find() from 20,769 to 10,349 calls during a -Qu operation, and results in a ~30% speedup of the same operation (0.35 sec -> 0.27 sec). This benefit should be apparent anywhere we read in the full contents of the sync databases. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-21Improve splitname memory allocationDan McGee1-14/+13
We don't need to create a temporary copy of the string if we are smart with our pointer manipulation and string copying. This saves a bunch of string duplication during database parsing, both local and sync. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-21Improve depends string parsingDan McGee1-33/+20
Remove the need for an unconditional string duplication by using pointer arithmetic instead, and strndup() instead of an unspecified-length strdup(). This should reduce memory churn a fair amount as this is called pretty frequently during database loads. Signed-off-by: Dan McGee <dan@archlinux.org>
