* Fix some database size estimation problemsDan McGee2011-02-15
| | | | | | | | | | * Use stat() and not lstat(); we don't care for the size of the symlink if it is one, we want the size of the reference file. * FS#22896, fix local database estimation on platforms that don't abide by the nlink assumption for number of children. * Fix a missing newline on an error message.

* Refactor out common code in pkghash add functionsPang Yan Han2011-02-07
| | | | | | | | | | 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.

* Improve pkghash_remove algorithmDan McGee2011-02-04
| | | | | | | | | | 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>
* Use alpm_list_remove_item in pkghash_removeDan McGee2011-02-04
| | | | | | | Removes the code that was duplicated and has now been refactored into a separate method. Signed-off-by: Dan McGee <dan@archlinux.org>
* Actually remove packages from pkghash on removalAllan McRae2011-02-04
| | | | | | | | Fully removes a package from the hash. Also unify prototype with removal from an alpm_list_t, fixing issues when removing a package from the pkgcache. Signed-off-by: Allan McRae <allan@archlinux.org>

* Rehash efficientlyAllan McRae2011-02-04
| | | | | | | Rehash without recreating the hash table list or reallocating the memory for holding the list nodes. Signed-off-by: Allan McRae <allan@archlinux.org>
* Slightly more efficient rehash size selectionAllan McRae2011-02-04
| | | | | | | | | 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>
* Error handling for maximum database sizeAllan McRae2011-02-04
| | | | | | | | 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>
* Implement a quick and dirty rehash functionDan McGee2011-02-04
| | | | | | | | 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>
