* Completely rework delta algorithmChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | 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.

* Add an archive_fgets() functionDan McGee2008-03-27
| | | | | | | | This crude function allows reading from an archive on a line-by-line basis similar to the familiar fgets() call on a FILE stream. This is the first step in being able to read DB entries straight from an archive. Signed-off-by: Dan McGee <dan@archlinux.org>
* libalpm: clean up of md5sum functions.Chantry Xavier2008-02-27
| | | | | | | | | test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum, and only used once, so not very useful. I removed them. Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated, so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

* Ensure correct dir permissions in the database.Chantry Xavier2008-01-13
| | | | | | | | | | | | Fix for FS#9176. A previous commit (6e8daa553bbd5) already forced all database files to 644. Now the directories are also forced to 755. Additionally, repo-add now sets the umask to 022, just like makepkg does, to fix the problem at its root.

* util.c : fix segfault when the cachedir isn't usable.Chantry Xavier2008-01-13
| | | | | | | | | | | | For example, if the cachedir is a broken symlink or a non writable directory, pacman fallbacks to /tmp/. Just before doing that, it freed the handle->cachedirs list twice ! once in _alpm_filecache_setup, and once in alpm_option_set_cachedirs. So the first one was removed. Fixes FS#9186. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
* Don't stat cachedir immediatelyDan McGee2008-01-05
| | | | | | | | | | | | By attempting to stat the cachedir when we load the pacman config, pacman bails out if it is a non-existant directory, even if it will never be needed. This is unfortunate as it is only used for sync transactions anyway. Instead, wait until we need it in _alpm_filecache_setup to actually do anything. Reported as FS#9096.

* Force mode of all database files to 644Aaron Griffin2007-11-25
| | | | | | | | | | In the case of a packaging error where install or changelog had bad permissions, pacman respected the original permissions without trying to fix it - this means that some operations (changelog) artificially required root permissions to run In addition, minor function housekeeping on _alpm_unpack Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>

* libalpm: simplify sync db lastupdateDan McGee2007-11-16
| | | | | | | | | | | Legacy code is hitting the trash here. Remove unnecessary _alpm_time2string time storage abstraction in favor of just writing the time_t value to the disk. The only drawback is that everyone's sync DBs will have to be updated at least once so that the lastupdate values are stored right. :) Signed-off-by: Dan McGee <dan@archlinux.org>
* libalpm: fix lstat wrapper to actually use newpathDan McGee2007-11-11
| | | | | | | | Commit b55abdce7aebb142ce79da3aa3645afe7693a3c4 introduced an lstat wrapper function that never dereferences paths with a trailing slash, but still called lstat on path instead of newpath. Oops! Signed-off-by: Dan McGee <dan@archlinux.org>

* libalpm: use an lstat wrapper so we never dereference dir symlinksDan McGee2007-11-04
| | | | | | | | Linux lstat follows POSIX standards and dereferences a symlink pointing to a directory if there is a trailing slash. For purposes of libalpm, we don't want this so make a lstat wrapper that suppresses this behavior. Signed-off-by: Dan McGee <dan@archlinux.org>

* alpm: removed unused strtoupper wrapper, remove installeddate on parse_descfileDan McGee2007-09-23

* libalpm: add newlines to all strings passed to log callbackDan McGee2007-08-23
| | | | | | | | | This allows us to remove the hack in the frontend where we added a newline to everything coming out of the pm_printf functions, and instead let the developer put newlines where they want them. This should be the last hangover of that auto-newline stuff. Signed-off-by: Dan McGee <dan@archlinux.org>
* Post trial install changes, round oneDan McGee2007-08-21
| | | | | | | | | | | | | | A bunch of changes related to my first "real" install of pacman-git into /usr/local and trying to use it. * Shift some uses of free -> FREE in libalpm. * Move stat and sanity checks of config paths into libalpm from the config and argument parsing in pacman.c. * Fix issue where dbpath still was not defined early enough due to its requirement for being used in alpm_db_register. This should be rewritten so it doesn't have this dependency, but this will work for now. Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix for FS 6404 and functionalize some cachedir handling stuffDan McGee2007-08-20
| | | | | | | | | In order to best resolve bug 6404, move some cachedir handling stuff out of sync.c and into util.c and create two new functions: filecache_find and filecache_setup. sync.c was rewritten to use these, and alpm_fetch_pkgurl now also uses these routines.

* package.h: implement origin_data union in pmpkg_t structDan McGee2007-08-14
| | | | | | | | | | 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.

* Remove lockfile configuration from frontend, make it job of libalpmDan McGee2007-06-27
| | | | | | | | | | | | I previously introduced some patches to make just about every path in pacman/libalpm configurable; doing this with the lockfile seemed a bit too far and we really should just place the lockfile where it belongs- with the DB that needs locking.

* Fix wrong permissions on pacnew extractionDan McGee2007-06-27
| | | | | | | | | | | First reported here: http://bbs.archlinux.org/viewtopic.php?pid=261861 Newly created files were done with the standard umask, so those that are extracted seperately and copied to a .pacnew extension will have the wrong permissions.

* Remove logmask stuff from backend; switch logging callback to new pm_printfDan McGee2007-06-09
| | | | | | | | | | Remove the logmask functionality from the backend as it has been moved to the frontend, and change the logging callback function to use pm_printf. In addition, make much better use of va_list- use the args list instead of a arbitrarily chosen string to print to in the logging functions. Signed-off-by: Dan McGee <dan@archlinux.org>
* Move DB and cache dirs away from there dependence on ROOTDIRDan McGee2007-05-31
| | | | | | | | | | | | | | | | | | | This change allows us to use all autoconf specified paths, most notably $(localstatedir). It is quite a change and touches a lot of files, as all references to the DB and cache were done with the ROOTDIR as a prefix. * add --lock command-line option to pacman to specify the location of the lockfile (this can now be specified at configure time by setting the $localstatedir path). * Rip quite a few settings out of configure.ac as they are now picked by setting the paths during configure or make. * Fix bug with /tmp fallback for sync downloads not working correctly (related to root location, now the system tmp dir is used). * Simplified the parameters to some libalpm functions, and added get/set for the new lockfile option. * Renamed several of the DEFS to names without the PM_ prefix. Signed-off-by: Dan McGee <dan@archlinux.org>
* Allow $repo expansion in 'Server' config linesAaron Griffin2007-05-18
| | | | | | | | | | | | | Small change (addition of a 'strreplace' function) which replaces any $repo tokens found in a server line with the name of the repo or section being processed. While this is more simplistic than suggestions on flyspray, it works and I think it is cleaner. Merits can be discussed further. Ref: FS#6389 Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
* Remove unnecessary casts on malloc and elsewhereDan McGee2007-05-14
| | | | | | | | | We had many unnecessary casts, most of them dealing with malloc and other memory allocations. The variable type should take care of it; no need to do it explicitly. In addition, I caught a const error while removing the casts. Signed-off-by: Dan McGee <dan@archlinux.org>

* Big commit this time:Aaron Griffin2007-03-03
| | | | | | | | | | | | | | | | | | | | | | | * 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

This has been reimplemented with a set-intersection scheme, due to the fact that file lists are always ordered. - NEEDS TESTING * Minor clean up, "globalized" the str_cmp helper to match the alpm comparison signature, so we can use it elsewhere.
* Debug logging changes:Aaron Griffin2007-01-31
| | | | | | | | | | | | | | | | * The --debug params were goofy. New setup allows --debug without params, --debug=<level> where level 1=debug output, 2=debug and download output, 3=debug, download, and function tracing output. This seems more sane to me. * Removed PM_LOG_FLOW1 and PM_LOG_FLOW2. They were just confusing. When adding new functions, it is near impossible to determin if your output should be "flow1" or "flow2" without tracking all the way up the call chain. Rarely would one ever say "ok, lets just show "flow2" output. These have both been replaced with PM_LOG_DEBUG * Removed the need for the root parameter on alpm_initialize. it is now defaulted to PM_ROOT just like dbpath and cachedir. This allows alpm to be initialized BEFORE option parsing in the front end, saving us some duplicate variables in the frontend. * Cleaned up front end variables due to early alpm_initialize call.
