2010-12-12be_files: write EPOCH instead of FORCEXavier Chantry1-3/+4
This patch is only meant for 3.4.x. It prepares the place for the future epoch-aware release. All force packages that get reinstalled or upgraded will get an EPOCH entry in the local database, and thus the new pacman with epoch won't reinstall them by mistake on the first -Su.

Basically I'm the idiot that thought I could make it better and completely forgot how freeing the contents of the original lists would screw up our nice little diff extraction lists.

2010-03-14Reduce duplicate code in DB extractionDan McGee1-37/+26

2010-03-14Only extract new DB entriesXavier Chantry1-12/+154
This implements FS#15198. The idea apparently came from Csaba Henk <csaba-ml <at> creo.hu> which submitted a patch to Frugalware, so thanks to him, even though I did not look at the code :) The idea is to only extract folders for new packages into the package database and clean up the old directories. This is essentially implementing Xyne's "rebase" script within pacman. If using -Syy, just remove and extract everything. If using -Sy : 1. Generate list of directories in DB 2. Generate list of directories in archive 3. Compare both 4. Clean up old directories 5. Extract new directories Original-work-by: Allan McRae <allan@archlinux.org> Signed-off-by: Xavier Chantry <shiningxc@gmail.com> [Dan: fix compile error, s/int/size_t/] Signed-off-by: Dan McGee <dan@archlinux.org>
2009-12-13Print error on duplicated database entriesNagy Gabor1-0/+7
Some users reported duplicated database entries in /var/lib/pacman/local/, for example, both foo-1.0-1 and foo-2.0-1 subdirectories existed. (Bogus 3rd-party scripts, backup?) In this case pacman reported no error and its behaviour was mysterious. From now on, pacman detects this situation and prints an error message.

2009-11-15download: major refactor to address lingering issuesDan McGee1-91/+5
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.

2009-09-20Fully implement database lazy loadingDan McGee1-15/+24
Commit 34e1413d75 attempted to implement lazy loading of package databases. Although it took care of my main complaint (creating the database directory if it didn't exist), it didn't allow sync repos to be registered before alpm_option_set_dbpath() had been called. With this patch, we no longer compute the individual repository DB paths until necessary, allowing full lazy loading to work as intended, and allowing us to drop the extra setlibpath() calls from the frontend. This allows the changes introduced in a2cd48960 (but later reverted) to be added back in again. Signed-off-by: Dan McGee <dan@archlinux.org>

2009-01-20Delay the creation of local and sync db dir.Xavier Chantry1-12/+31
We don't need to create the directories when local or sync dbs are registered. For example, if a sync db does not exist, we cannot even do "pacman -Q" as an user. Instead, we can create the local db if needed during the db_prepare operation, and sync dbs on db_update. Also remove some more useless abstractions in db_update and switch to a much more efficient way to remove a sync db : rm -rf. Signed-off-by: Xavier Chantry <shiningxc@gmail.com>
2009-01-20Remove some db abstraction crap.Xavier Chantry1-32/+8

Changelogs and install files were getting extracted into the local db folder before it was manually created.

2008-06-04Get rid of double / in database paths.Xavier Chantry1-29/+61
Errors like the following one happen regularly (for unknown reasons...) : error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No such file or directory Anyway, every time an user reported an error like that, it always seemed like he thought the error was caused by the double /, which is obviously wrong. Since db->path always include a trailing /, there is no need to add one when concatenating paths in be_files.c or add.c. Additionally, some static strings were switched to dynamic. And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored in db_read, db_write and db_remove with a get_pkgpath static function.

2008-06-04Use correct C type for file sizesDan McGee1-5/+5
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.

2008-05-29be_files : stores REPLACES and FORCE in desc.Xavier Chantry1-11/+10
repo-add and db_read both assume that REPLACES and FORCE fields are in the desc file, so do that for db_write as well (instead of depends file). Note that db_write is currently only used on the local database. And the only purpose of replaces and force in local database is for information purpose (available on -Qi operations). So this is not a big problem.

2008-05-13Fix rewinddir regression by cleaning up db_scanXavier Chantry1-75/+31
Commit 046003844739416ff6d168dd2dec76490adb0727 caused a regression when rereading the pkgcache after updating the on-disk databases. A rewinddir call was errantly removed. Instead of replacing the call to rewindir, clean up this whole mess. db_scan is used only once and with target == NULL so there was actually half the code of db_scan which was unused. This is gone now and replaced by a single new db_populate function. Dan: add_sorted ended up being 3x slower than one msort at the end, so I changed back to that. I also made one pointer variable const and merged this whole patch with my original fix for the rewinddir issue.

2008-01-21Move the deptest code from frontend to backend.Chantry Xavier1-1/+1
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.

This also affects all structures with static strings, such as depmiss, conflict, etc. This should help a lot with memory usage, and hopefully make things a bit more "idiot proof". Currently our pactest pass/fail rate is identical before and after this patch. This is not to say it is a perfect patch- I have yet to pull valgrind out. However, this should be quite safe to use in all situations from here on out, and we can start plugging the memleaks.

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.

2007-11-14Move alpm_splitdep usage to db_readDan McGee1-2/+6
Holy inefficient batman! For a pacman -Qt operation (when we are using compute_requiredby and not database entries), splitdep was being called ~1.3 million times on my local database. By splitting when we read the DB, we drop this number to around 1700 and save a LOT of time in doing so (a 5x increase in pacman -Qt speed here).

However, it missed a few things: * If we weren't in the C/POSIX/en_US locale, the date parsing would fail as it tried to use the abbreviations of the locale being used. Fix this by switching the LC_TIME value before we parse a date. * We used ctime to print the date value, which is always the C locale string. Instead, use strftime to print a localized date string.
