2011-03-23Refactor signature loading code into common functionDan McGee
We can use this for both standalone package signatures as well as standalone database signatures. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-23Add functions for verifying database signatureAllan McRae
Add a pmpgpsig_t struct to the database entry struct and functions for the lazy loading of database signatures. Add a function for checking database signatures, reusing (and generalizing) the code currently used for checking package signatures. TODO: The code for reading in signature files from the filesystem is duplicated for local packages and database and needs refactoring. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-03-23Added gpg verification options per repo to the config file.Xavier Chantry
Once we do this, add support for VerifySig to pactest. We just check if the repo name contains Always, Never or Optional to determine the value of VerifySig. The default is Never. pacman uses Always by default but this is not suitable for pactest.

2011-03-23Remove unnecessary sanity check on db->setserverDan McGee
We pass in a db object, so no need to go looking for it in the list on the handle. This is a remnant of when we passed in a treename, more than likely. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-20Style change: return(x) --> return xDan McGee
This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-28Check local DB version before continuing transactionDan McGee
Ensure we have a local DB version that is up to par with what we expect before we go down any road that might modify it. This should prevent stupid mistakes with the 3.5.X upgrade and people not running pacman-db-upgrade after the transaction as they will need to. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-25alpm: alpm_db_get_pkgcache_list => alpm_db_get_pkgcacheDave Reisner
This avoids needless breakage of the public API. Signed-off-by: Dave Reisner <d@falconindy.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-25alpm: remove public visibility of pmpkghash_tDave Reisner
There's no API functions exposed which allow manipulation of this type, so remove it from public view. Also, rename the public and private alpm_db_get_pkgcache symbol to alpm_db_get_pkgcache_has. Signed-off-by: Dave Reisner <d@falconindy.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Actually remove packages from pkghash on removalAllan McRae
Fully removes a package from the hash. Also unify prototype with removal from an alpm_list_t, fixing issues when removing a package from the pkgcache. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-02-04Read pkgcache into hashAllan McRae
Read the package information for sync/local databases into a pmpkghash_t structure. Provide a alpm_db_get_pkgcache_list() method that returns the list from the hash object. Most usages of alpm_db_get_pkgcache are converted to this at this stage for ease of implementation. Review whether these are better accessing the hash table directly at a later stage. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-01-29Remove need to explicitly register the local DBDan McGee
Perform the cheap struct and string setup of the local DB at handle initialization time to match the teardown we do when releasing the handle. If the local DB is not needed, all real initialization is done lazily after DB paths and other things have been configured anyway. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-07Fix some more simple conversion "errors"Dan McGee
None of these warn at the normal "-Wall -Werror" level, but casts do occur that we are fine with. Make them explicit to silence some warnings when using "-Wconversion". Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-12dirent usage cleanupDan McGee
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.

2010-10-14Move and rename splitnameAllan McRae
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 McRae
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 McRae
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 McRae
Put the db_operations struct to use and completely split the handling of the sync and local databases. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-14Separate be_files into be_sync and be_localAllan McRae
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 db cache handling functionsAllan McRae
These will be needed for the handling of both local and sync database caches, so put them in a common location. Signed-off-by: Allan McRae <allan@archlinux.org>
2010-10-13Move database handling utility functionsAllan McRae
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>

2010-10-13Initial hack at a DB operations structDan McGee
It doesn't do a whole lot yet, but these type of operations will potentially be different for the DBs we load. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-10-13Move the cache stuff where it should beDan McGee
Cache bullshit only has relevance to be_files, so move it there. Signed-off-by: Dan McGee <dan@archlinux.org> [Allan: BIG rebase] Signed-off-by: Allan McRae <allan@archlinux.org>
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>

2009-10-11int 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. Signed-off-by: Dan McGee <dan@archlinux.org>
2009-09-20Fully implement database lazy loadingDan McGee
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>

2009-06-23Search package groups when searching a DBDan McGee
See FS#13099. This makes sense especially for the pacman frontend, as we show groups in the search output. Signed-off-by: Dan McGee <dan@archlinux.org>
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>
2009-01-20Delay the creation of local and sync db dir.Xavier Chantry
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 Chantry
These db_open and db_close looked quite useless. And they caused the db directory to be opened on a simple registering of a database. This is totally unneeded, this opening can be delayed to when we actually need it. Signed-off-by: Xavier Chantry <shiningxc@gmail.com>

2008-08-08Fix variable naming issues in _alpm_db_cmpDan McGee
When this function got a rewrite in commit f43805d875, argument and variable names got a bit mixed up when separating the casts from the strcmp operation. Fix the mixup which also fixes a possible segfault when this function is called. Signed-off-by: Dan McGee <dan@archlinux.org>
2008-08-05Avoid double slashes in URLs given to libdownload.Xavier Chantry
If a Server specified in pacman.conf had a trailing slash, libalpm ended up building URLs with double slashes, and this broke libdownload with errors like the following one : error: failed retrieving file 'redland-1.0.8-1-i686.pkg.tar.gz' from 192.168.0.90 : Command okay So the public function alpm_db_set_server will make sure to remove the trailing slash of servers. For the private function _alpm_download_single_file, I only added a comment. Signed-off-by: Xavier Chantry <shiningxc@gmail.com> 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. Signed-off-by: Dan McGee <dan@archlinux.org>
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.

2008-05-11Remove some useless abstraction and start db cleanupDan McGee
We have some useless abstractions like an alpm_db_rewind function. I've read somewhere that readdir() was the worst filesystem function call invented, and what do we do? Add a wrapper around it. Kill this abstraction and move some other things into be_files that should be there anyway because they are so tied to how a files backend works. Signed-off-by: Dan McGee <dan@archlinux.org>

2008-03-23Update database mtime after it has been extractedDan McGee
This will reduce the need for running an -Syy if the DB was only half-extracted, as the mtime won't get updated until the new database is completely in place. 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>
2008-02-24Add new stub download functions for use throughout the codeDan McGee
Add new stub functions that work by calling the existing (terrible) download forreal function, which needs a serious overhaul. Hide the existing functions and switch all former users to the new functions. Signed-off-by: Dan McGee <dan@archlinux.org>
