2009-07-22Add a fetch callback to allow front-end download supportSebastian Nowicki
This allows a frontend to define its own download algorithm so that the libfetch dependency can be omitted without using an external process. The callback will be used when if it is defined, otherwise the old behavior applies.

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>
2009-01-12Rename alpm_get_md5sum to alpm_compute_md5sum and alpm_dep_get_string to ↵Nagy Gabor
alpm_dep_compute_string This patch introduces the following function name convention: _compute_ in function name: the return value must be freed. _get_ in function name: the return value must not be freed.

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.

2008-10-31-Qu reworkNagy Gabor

2008-08-23Move -Sp implementation to the front-endNagy Gabor
This patch kills one of our hackish pseudo transactions: PRINTURIS. (The other one is -Sw) From now on, front-end must not call trans_commit in case of -Sp, it should print the uris of target packages "by hand" instead. PRINTURIS flag was removed, NOCONFLICTS flag can be passed to skip conflict checks. Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>

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. Signed-off-by: Dan McGee <dan@archlinux.org>
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.

2008-04-29Add documentation for transaction eventsSebastian Nowicki
It is hard to decipher what the transaction events actually notify you of, and what parameters are passed to the callback function, without looking at the code.

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. This will allow us much greater flexibility in the usage of deltas (maybe even sync DBs some day) as well as allowing code outside of delta.h/delta.c to be much cleaner with less of a need for snprintf() calls.

2008-04-06Allow disabling of internal (libdownload) codeDan McGee
Add a new --disable-internal-download flag to configure allowing the internal download code to be skipped. This will be helpful on platforms that currently don't support either libdownload or libfetch (such as Cygwin) and for just compiling a lighter weight pacman binary. This was made really easy by our recent refactoring of the download code into separate internal and external functions, as well as some error code cleanup.

2008-03-10Remove trans->targetsNagy Gabor
Its implementation was quite broken: * add_loadtarget() might have silently filtered out some targets when replacing an older version. * This was used in sync.c to determine whether a target is implicit or not, which is incorrect behavior. Before this patch we silently removed user confirmed replacements; now we always warn on a replacement. * remove001.py behavior was quite odd in adding same target 5 times to the target list, we can change this behavior to be a failure.

2008-02-27libalpm: clean up of md5sum functions.Chantry Xavier
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>
2008-02-27Start removing some junk from the function templateDan McGee
I screwed up originally when I accepted the TotalDownload patch, 8ec27835f40e3df1ce409bc3d913587c474a30c3. I didn't realize how deeply it modified libalpm and I probably shouldn't have let it do what it did. This commit reverts much of what that patch added in order to clean up our internal function calls. We can find another way to do it right down the road here but for now it has to go. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-02-24Remove pmserver_t abstractionDan McGee
Remove what was a pretty weird abstraction in the libalpm backend. Instead of parsing server URLs as we get them (of which we don't usually use more than a handful anyway), wait until they are actually used, which allows us to store them as a simple string list instead. This allows us to remove a lot of code, and will greatly simplify the continuing refactoring of the download code. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-02-16Move pmgraph_t struct and functions to their own header fileDan McGee

2008-02-06New remove option : -u / --unneeded (FS#6505).Nagy Gabor
With --unneeded option 'pacman -R' doesn't stop in case of dependency error; it removes the needed-dependency targets from the target-list instead. See also: http://archlinux.org/pipermail/pacman-dev/2007-October/009653.html . The patch also adds a new causingpkg field to pmdepmissing_t which indicates the to-be-removed package which would cause a dependency break. This is needed, because miss->depend.name may be a provision. miss->causingpkg will be useful in -R dependency error messages too. [Xavier: renamed inducer to causingpkg, removed the _alpm_pkgname_pkg_cmp helper function as requested by Aaron. This might be added by a further commit.

Instead of using type = UPGRADE or DEPEND, we now rather use a "pmpkgreason_t newreason" field directly (= explicit or depend) which allows a better handling of the install reason.

This function has a limited purpose, but might be interesting to do a sanity check from a frontend (eg testdb). Also removed the private _alpm_checkconflicts function to avoid confusion. This function was used only once in libalpm, in sync.c, and was just a single line anyway.

2008-01-21Move the deptest code from frontend to backend.Chantry Xavier
The deptest code (pacman -T) used by makepkg was mostly in the frontend. There were 2 drawbacks: 1) the public splitdep function returns a pmdepend_t struct, but the _alpm_dep_free function for freeing it is private. So there was a memleak. 2) there is a helper in the backend (satisfycmp in deps.c) which makes this function much easier. So this adds a new public alpm_deptest in libalpm/deps.c, which cleans pacman_deptest in pacman/deptest.c a lot. Besides, alpm_splitdep was made private, because the frontend no longer requires it, and _alpm_dep_free is also private. Finally the deptest001 pactest was extended.
