2010-12-12Add configuration option to control disk space checkingAllan McRae4-4/+24
Disk space checking is likely to be an unnecessary bottleneck to people with reasonable partition sizes so add a configuration option to allow it to be disabled/enabled as wanted. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Implement disk space checkingAllan McRae3-1/+45
Pull together the work of the previous commits to implement a check for enough free space before performing an install transaction. Abort if there is not enough free space with an appropriate pm_errno.. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Add functions to calculate approximate disk usage by packagesAllan McRae1-0/+100
Two helper function are added to calculate the disk usage from packages that are either currently installed on the system or from a package archive. Some minor approximations have been made: 1. Size for directories is not considered when removing a package from the filesystem to avoid multiple counting across packages. Also, these are reported to take zero size while installing. 2. Symlinks are reported to contribute zero size towards removal as libarchive reports them to have zero size for install. 3. Package data files (.PKGINFO, .INSTALL, .CHANGELOG) are counted towards usage on dbpath on install, but their size is not counted on package removal. 4. No handling of extra size needed for .pacsave/.pacnew files. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Add function to match file to mount pointAllan McRae1-0/+28
For a given file, determine which mount point it is on or will be installed to. Take into account that we might be using an alternative installation root. Add additional helper function added to sort mount point list for easier matching. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Add function for listing system mount pointsAllan McRae2-0/+139
Add a mount_point_list() function that attempts to portably obtain a list of system mount points and a struct to hold needed mount point information. Abort the transaction if we are unable to determine the mount points. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

Very basic prototyping for adding functionality to check free disk space before performing package installs. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12Remove AC_TYPE_SIGNAL usageDan McGee1-1/+1

2010-12-12dirent usage cleanupDan McGee4-4/+1
We were including the header in a lot of places it is no longer used. Additionally, use the correct autoconf macro for determining whether d_type is available as a member: HAVE_STRUCT_DIRENT_D_TYPE.

This will allow us to eventually combine the depends and desc entries within the sync database. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12alpm/remove.c : respect --dbonly during remove-upgradeXavier Chantry1-0/+5
When a -Sk or -Uk operation induced a removal of an existing local package, --dbonly was not in effect and the files were all removed. Fixing this behavior was already marked as TODO in database012 pactest ------------ TODO: I honestly think the above should NOT delete the original les, it hould upgrade the DB entry without touching anything on the file stem. E.g. this test should be the same as: pacman -R --dbonly dummy && pacman -U --dbonly dummy.pkg.tar.gz ------------ Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com> [Dan: small coding style touchup] Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12alpm: don't expose alpm_depcmpXavier Chantry5-9/+9
Either we expose all low levels function dealing with pmdepend_t (splitdep and depfree come to mind), or we don't. Since none of the tools use depcmp, I chose to remove it. In the future, we might want to expose higher level functions such as alpm_find_satisfier, or just lower level functions like splitdep and depfree together with depcmp.

2010-12-12alpm: kill alpm_deptestXavier Chantry2-26/+0
This has been replaced by the more flexible alpm_find_satisfier function, and alpm_deptest was completely unsused now. Signed-off-by: Xavier Chantry <chantry.xavier@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-12alpm: add new alpm_find_satisfier functionXavier Chantry2-0/+15
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.

2010-12-12be_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.

2010-12-10Fix possible null pointer deref in check_archDan McGee1-1/+1
If we have a corrupted database, a package can come through without an arch, causing the code to blow up when making strcmp() calls. It might even be possible with perfectly valid database entries lacking an 'arch =' line. This behavior was seen as at least one of the problems in FS#21668. Ensure pkgarch is not null before doing anything further. Signed-off-by: Dan McGee <dan@archlinux.org>

[Y/n] ( 1/15) removing kde-meta-kdewebdev [------------------------] 100% $ it stopped here.. On one side, libalpm did not initialize the progress bar at 0 percent. So with meta-packages that have 0 files, there was only one progress bar call with percent == 100. On the other side, pacman callback kept track of the last percent that it received. When there are only meta-packages, we always received only 100, so pacman believed the progress bar needed not update. Thus only the first package was actually displayed. A proper fix for the callback would be to keep track of last package name to make sure the recorded prev percent applies. But since we now specify that both Add and Remove should at least send percent=0 at beginning and percent=100 at the end, there is no need for that.

2010-10-14be_package: read force entry and convert to epochXavier Chantry1-0/+5

Local packages do not have deltas so remove lazy loading of delta information. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-14Move and rename splitnameAllan McRae6-50/+49
The splitname function is a general utility function and so is better suited to util.h. Rename it to _alpm_splitname to indicate it is an internal libalpm function as was the case prior to splitting local and sync db handling. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-14Restrict visibility of checkdbdir and get_pkgpathAllan McRae3-39/+34
These functions are only needed by be_local and were only promoted to db.{h,c} as part of the splitting of handling the local and sync dbs. Move them into be_local.c and make them static again. Signed-off-by: Allan McRae <allan@archlinux.org>

2010-10-14Populate sync db from archiveAllan McRae3-27/+42
Read in list of packages for sync db from tar archive. Breaks reading in _alpm_sync_db_read and a lot of pactests (which is expected as they do not handle sync db in archives...). Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-14Completely separate local and sync db handlingAllan McRae6-77/+81

2010-10-14Separate be_files into be_sync and be_localAllan McRae8-325/+943
The file be_files.c is "split" to be_local.c and be_sync.c in order to achieve separate handling of sync and local databases. Some basic clean-up of functions that are only of use for local or sync databases has been performed and some rough function renaming in duplicated code has been performed to prevent compilation errors. However, most of the clean-up and final separation of sync and local db handling occurs in following patches. Signed-off-by: Allan McRae <allan@archlinux.org>

2010-10-13Move database handling utility functionsAllan McRae3-74/+81
Move splitname, checkdbdir, get_pkgpath into db.{h,c} as these will be needed to parse both the local and sync databases during the initial splitting. They will be moved out of db.{h,c} at to more appropriate locations at a later stage. Signed-off-by: Allan McRae <allan@archlinux.org>

2010-10-13Complete rework of package accessor logicDan McGee5-92/+398
Hopefully we've finally arrived at package handling nirvana, or at least this commit will get us a heck of a lot closer. The former method of getting the depends list for a package was the following: 1. call alpm_pkg_get_depends() 2. this method would check if the package came from the cache 3. if so, ensure our cache level is correct, otherwise call db_load 4. finally return the depends list Why did this suck? Because getting the depends list from the package shouldn't care about whether the package was loaded from a file, from the 'package cache', or some other system which we can't even use because the damn thing is so complicated. It should just return the depends list. So what does this commit change? It adds a pointer to a struct of function pointers to every package for all of these 'package operations' as I've decided to call them (I know, sounds completely straightforward, right?). So now when we call an alpm_pkg_get-* function, we don't do any of the cache logic or anything else there- we let the actual backend handle it by delegating all work to the method at pkg->ops->get_depends. Now that be_package has achieved equal status with be_files, we can treat packages from these completely different load points differently. We know a package loaded from a zip file will have all of its fields populated, so we can set up all its accessor functions to be direct accessors. On the other hand, the packages loaded from the local and sync DBs are not always fully-loaded, so their accessor functions are routed through the same logic as before. Net result? More code. However, this code now make it roughly 52 times easier to open the door to something like a read-only tar.gz database backend. Are you still reading? I'm impressed. Looking at the patch will probably be clearer than this long-winded explanation.

2010-10-13Allow local and sync db to be treated separatelyDan McGee5-34/+37
Implement this seemingly simple change in package.h: typedef enum _pmpkgfrom_t { - PKG_FROM_CACHE = 1, - PKG_FROM_FILE + PKG_FROM_FILE = 1, + PKG_FROM_LOCALDB, + PKG_FROM_SYNCDB } pmpkgfrom_t; which requires flushing out several assumptions from around the codebase with regards to usage of the PKG_FROM_CACHE value. Make some changes where required to allow the switch, and now the correct value should be set (via a crude hack) depending on whether a package was loaded as an entry in a local db or a sync db. This patch underwent some big rebasing from Allan and Dan. Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-13Unify caching concerns in package accessorsDan McGee1-181/+30
Move almost all of the caching related stuff into a single #define (which should maybe even just be a static function) so we don't duplicate logic all over the place. This also makes the code a heck of a lot shorter and means further changes to this stuff don't have to touch each and every getter function. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-10-11Read 'force' entry from packagesDan McGee1-0/+2
We weren't reading this in from our packages, thus causing us not to write it out to our local database. Adding this now will help ease the upgrade path for epoch later and not require reinstallation of all force packages. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-10-11Avoid stat call to determine is_directory if possibleDan McGee1-10/+19
On Linux and OS X, we can determine if an entry obtained through a readdir() call is a directory without also having to stat it. This can save a significant number of syscalls. The performance increase isn't dramatic, but it could be on some platforms (e.g. Cygwin) so it shouldn't hurt to use this unconditionally where supported. Signed-off-by: Dan McGee <dan@archlinux.org>
