2010-12-12alpm: add new alpm_find_satisfier functionXavier Chantry
whatprovides and splitdep were removed, so depcmp alone is quite useless now without splitdep, and deptest is not flexible enough. Introduce a new alpm_find_satisfier which is hopefully more flexible, this should make implementation of deptest very easy, and also help alpm tools such as pactree.

2010-05-05Introduce -D, --databaseNagy Gabor
The request of FS#12950 is implemented. On the backend side, I introduced a new function, alpm_db_set_pkgreason(), to modify the install reason of a package in the local database. On the front-end side, I introduced a new main operation, -D/--database, which has two options, --asdeps and --asexplicit. I documented this in pacman manual. I've created two pactests to test -D: database001.py and database002.py. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

2009-11-15download: major refactor to address lingering issuesDan McGee
Sorry for this being such a huge patch, but I believe it is necessary for quite a few reasons which I will attempt to explain herein. I've been mulling this over for a while, but wasn't super happy with making the download interface more complex. Instead, if we carefully order things in the internal download code, we can actually make the interface simpler. 1. FS#15657 - This involves `name.db.tar.gz.part` files being left around the filesystem, and then causing all sorts of issues when someone attempts to rerun the operation they canceled. We need to ensure that if we resume a download, we are resuming it on exactly the same file; if we cannot be almost postive of that then we need to start over. 2. http://www.mail-archive.com/pacman-dev@archlinux.org/msg03536.html - Here we have a lighttpd bug to ruin the day. If we send both a Range: header and If-Modified-Since: header across the wire in a GET request, lighttpd doesn't do what we want in several cases. If the file hadn't been modified, it returns a '304 Not Modified' instead of a '206 Partial Content'. We need to do a stat (e.g. HEAD in HTTP terms) operation here, and the proceed accordingly based off the values we get back from it. 3. The mtime stuff was rather ugly, and relied on the called function to write back to a passed in reference, which isn't the greatest. Instead, use the power of the filesystem to contain this info. Every file downloaded internally is now carefully timestamped with the remote file time. This should allow the resume logic to work. In order to guarantee this, we need to implement a signal handler that catches interrupts, notifies the running code, and causes it to set the mtimes on the file. It then rethrows the signal so the pacman signal handler (or any frontend) works as expected. 4. We did a lot of funky stuff in trying to track the DB last modified time. It is a lot easier to just keep the downloaded DB file around and track the time on that rather than in a funky dot file. It also kills a lot of code. 5. For GPG verification of the databases down the road, we are going to need the DB file around for at least a short bit of time anyway, so this gets us closer to that.

2009-10-11int typing: s/unsigned short/int/ in libalpmDan McGee
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.
2009-09-08Add a new reason field to pmconflict_t structNagy Gabor
Sometimes "foo conflicts with bar" information is not enough, see this thread: http://bbs.archlinux.org/viewtopic.php?id=77647. That's why I added a new reason field to our pmconflict_t struct that stores the packager- defined conflict that induced the fact that package1 conflicts with package2. I modified the front-end (in callback.c, sync.c, upgrade.c) to print this new information as well. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu>

2009-07-22Add a fetch callback to allow front-end download supportSebastian Nowicki

2009-07-22Introduce -SuuNagy Gabor
If the user switches from unstable repo to a stable one, it is quite hard to sync its system with the new repo (the user will see many "Local is newer than stable" messages, nothing more). That's why I introduced -Suu, which treats a sync package like an upgrade, iff the package version doesn't match with the local one's. I added a new pactest (sync104.py) to test this, and I updated the documentation of -Su.

2009-06-08Give sensible feedback when a repo has no configured serversDan McGee
This fixes FS#14899. When running an -Sp operation without servers configured for a repository, we would segfault, so add an assert to the backend method returning the first server preventing a null pointer dereference. In addition, add a new error code to libalpm that indicates we have no servers configured for a repository. This makes -Sy and -S <package> operations fail gracefully and helpfully when a repo is set up with no servers, as the default mirrorlist in Arch is provided this way. Signed-off-by: Dan McGee <dan@archlinux.org>
2009-06-01Introduce PM_TRANS_FLAG_NOLOCKNagy Gabor
This flag indicates that the front-end will not call alpm_trans_commit(), so the database needn't be locked. This is the first step toward fixing FS#8905. If this flag is set, alpm_trans_commit() does nothing and returns with an error (that has new code: PM_ERR_TRANS_NOT_LOCKED).

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.

2009-04-11New error type: PM_ERR_PKG_IGNOREDNagy Gabor
This patch fixes FS#12059. Now sync_addtarget can return with PM_ERR_PKG_IGNORED, which indicates that although the requested package was found it is in ignorepkg, so alpm could not add it to the transaction. So the front-end can decide what to do. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
2009-02-28libalpm: remove from_md5 and to_md5 from pmdelta_tXavier Chantry
The from_md5 and to_md5 fields were a nice extra safety, which would avoid trying to apply deltas on corrupted package files. However, they are not strictly necessary, since xdelta should be able to detect that on its own. The main problem is that it is impossible to compute these informations from the delta only. So repo-add would not be able to compute the delta entry based on just the delta file. Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2009-02-23Enabled new interactive prompt and updated some testsBryan Ischo
Enabled a new prompt to ask the user if they'd like to remove unresolvable packages from the transaction rather than failing it. Many pactest tests that used to fail now return success codes, because pacman now issues a prompt allowing the user to cancel rather than failing many transactions, and the pactest scripts always choose to cancel with no error rather than failing. The only net effect is that the return status of pacman is now 0 in cases where it used to be nonzero. Signed-off-by: Bryan Ischo <bryan@ischo.com> Signed-off-by: Dan McGee <dan@archlinux.org>

2009-01-12HoldPkg reworkNagy Gabor
The HoldPkg feature is even more important when the packages to be held are pulled automatically by pacman, in a -Rc and -Rs operation. Before, it only applied when the packages were explicitly requested by the user to be removed. This patch extends holdpkg to -Rc and -Rs by doing the HoldPkg check just before trans_commit. Additionally, the whole HoldPkg stuff was moved to the front-end. I changed the default behavior to "don't remove", so I modified remove030.py pactest as well. See also: FS#9173.

2008-08-23Cleanup of _alpm_pkg_compare_versions.Xavier Chantry
* 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.

2008-07-13sync_addtarget reworkNagy Gabor
Now '-S provision' handling is done in the back-end. In case of multiple providers, the first one is selected (behavior change: deleted provision002.py). The old processing order was: literal, group, provision; the new one: literal, provision, group. This is more rational, but "pacman -S group" will be slower now. "pacman -S repo/provision" also works. Provision was generalized to dependencies, so you can resolve deps by hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be useful in makepkg dependency resolving. The changes were documented in pacman manual. alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were removed, since they are no longer needed. I added some verbosity to "select provider instead of literal" and "fallback to group". Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
2008-06-04Reimplement TotalDownload functionalityDan McGee
Add a new totaldlcb callback function to libalpm and make pacman utilize it when the TotalDownload option is enabled. This callback function is pretty simple- it is meant to be called once at the beginning of a "list download" action, and once at the end (with value 0 to indicate the list has been finished). The frontend is responsible for keeping track of adding individual file download amounts to the total xfered amount in order to display some sort of overall progress.

2008-06-04Use correct C type for file sizesDan McGee
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.

2008-05-13Cleanup usages of alpm_list_find and alpm_list_remove.Chantry Xavier
* remove obsolete and unused *_cmp helper functions like deppkg_cmp and _alpm_grp_cmp * new alpm_list_remove_str function, used 6 times in handle.c * remove _alpm_prov_cmp / _alpm_db_whatprovides and replace them by a more general alpm_find_pkg_satisfiers with a cleaner implementation. before: alpm_db_whatprovides(db, targ) after: alpm_find_pkg_satisfiers(alpm_db_getpkgcache(db), targ) * remove satisfycmp and replace alpm_list_find + satisfycmp usage by _alpm_find_dep_satisfiers. before : alpm_list_find(_alpm_db_get_pkgcache(db), dep, satisfycmp) after : _alpm_find_dep_satisfiers(_alpm_db_get_pkgcache(db), dep) * remove _alpm_pkgname_pkg_cmp, which was used with alpm_list_remove, and use _alpm_pkg_find + alpm_list_remove with _alpm_pkg_cmp instead. This commit actually get rids of all complicated and asymmetric _cmp functions. I first thought these functions were worth it, be caused it allowed us to reuse list_find and list_remove. But this was at the detriment of the clarity and also the ease of use of these functions, dangerous because of their asymmetricity.

2008-04-26Completely rework delta algorithmChantry Xavier
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.

2008-04-26Rework delta struct and modify code accordinglyDan McGee
Start to move the delta struct away from an assumed package name scheme and towards something that is package (or even filename) agnostic.
