2011-06-03Add handle attribute to pmpkg_t structDan McGee1-1/+2
Similar to what we just did for the database; this will make it easy to always know what handle a given package originated from. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Add handle attribute to pmdb_t structDan McGee1-0/+1
This is the first step in a long process to remove our dependence on the global handle variable we currently share in libalpm, with the goal to make things a bit more thread-safe and re-entrant. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Remove ALPM_LOG_FUNC macroDan McGee1-7/+0
The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-05Remove sync DB reregister checkDan McGee1-10/+0
It's your own damn fault if you do this, and this code is remnants from an old time when we weren't very good at coding. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-05Merge branch 'maint'Dan McGee1-5/+6
2011-05-05Ensure populate error return codes are consistentDan McGee1-5/+6
It must be -1 to differentiate it from a number of packages loaded count. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-05Logging changes during DB loadDan McGee1-0/+2
The switch from FUNCTION to DEBUG was ill-advised inside the local database load. Instead, add a DEBUG level logger to both local and sync database loads that shows the number of packages processed. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-04Deal with unused function parameters correctlyAllan McRae1-1/+1
This started off removing the "(void)foo" hacks to work around unused function parameters and ended up fixing every warning generated by -Wunused-parameter. Dan: rename to UNUSED. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24Rein in the complexity of the signature typeDan McGee1-1/+1
Given that we offer no transparency into the pmpgpsig_t type, we don't really need to expose it outside of the library, and at this point, we don't need it at all. Don't decode anything except when checking signatures. For packages/files not from a sync database, we now just read the signature file directly anyway. Also push the decoding logic down further into the check method so we don't need this hanging out in a less than ideal place. This will make it easier to conditionally compile things down the road. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-23libalpm/dload: major refactor of signature downloadingDan McGee1-53/+35
There's a lot of related moving parts here: * Iteration through mirrors is moved back to the calling functions. This allows removal of _alpm_download_single_file and _alpm_download_files. * The download function gets a few more arguments to influence behavior. This allows several different scenarios to customize behavior: - database - database signature (req'd and optional) - package - package via direct URL - package signature via direct URL (req'd and optional) * For databases, we need signatures from the same mirror, so structure the code accordingly.

2011-04-21Header inclusion cleanupDan McGee1-2/+1
This does touch a lot of things, and hopefully doesn't break things on other platforms, but allows us to also clean up a bunch of crud that no longer needs to be there. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-04-02Fix compatibility with older versions of libarchive.Rémy Oudompheng1-0/+2
There is no reason to not support versions of libarchive that lack ARCHIVE_COMPRESSION_UU. Distributions should work properly without this. Signed-off-by: Rémy Oudompheng <remy@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-01Ensure dbpath is not null when populating sync databaseDan McGee1-3/+12
We didn't do this sanity check before trying to open an archive. If the alpm dbpath wasn't set, the sync database dbpath would be NULL, causing us to hang indefinitely in archive_read_open_filename() rather than erroring out. We already have a corresponding check in local_db_populate(). The following program will test this case, and hangs before this patch without the call to set_dbpath: int main(int argc, char *argv[]) { alpm_initialize(); // alpm_option_set_dbpath("/var/lib/pacman/"); pmdb_t *core = alpm_db_register_sync("core"); pmpkg_t *pkg = alpm_db_get_pkg(core, "pacman"); return 0; } Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-01Ignore upcoming new values in sync backendDan McGee1-0/+6
PGPSIG and SHA256SUM are new and we can safely ignore them for now if we come across them. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-24Do not reuse old signatureAllan McRae1-2/+9
After updating a database, remove the old signature to prevent it being used in validation if the new signature fails to download. Signed-off-by: Allan McRae <allan@archlinux.org>
2011-03-24Download and verify package database signaturesAllan McRae1-6/+38
If signature verification is needed, attempt to download a signature file for a repo when it is updated. Return an error if unable to download signature only when checking is mandatory, or if signature is invalid. TODO: At the moment the database signature is only checked on download. Should we do anything with a database if it fails to be verified to prevent its future usage? Signed-off-by: Allan McRae <allan@archlinux.org>

2011-03-23repo-add: add sha256sum values to repo databaseDan McGee1-0/+3
Implements FS#23103. Also modify libalpm so it ignores this value without any warning as we know it is likely to exist. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-21Style change: return(x) --> return xDan McGee1-10/+10
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>

2011-03-17Correctly parse %DELTAS% entries in sync DBtuxce1-1/+6
We erroniously dropped the call to _alpm_delta_parse() when macro-izing, causing segfaults for repos that provide deltas. Addresses FS#23314. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-07Do not print warning with files entry in sync dbAllan McRae1-2/+4
repo-add can add a "files" entry into the sync db. Currently we do nothing with this file, so explicitly skip it to prevent unknown database file warnings. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-03-01Fix some easy to find double translationsDan McGee1-1/+1
A lot of these were places that should have used the same message but didn't, or were very easy to convert to using the same message and letting some of the burden off of the translators. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-28Check local DB version before continuing transactionDan McGee1-0/+6
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>
2011-02-15Fix some database size estimation problemsDan McGee1-4/+5
* Use stat() and not lstat(); we don't care for the size of the symlink if it is one, we want the size of the reference file. * FS#22896, fix local database estimation on platforms that don't abide by the nlink assumption for number of children. * Fix a missing newline on an error message.

2011-02-08Handle null pkgcache for local/sync db_populate()Pang Yan Han1-1/+7
In sync_db_populate() and local_db_populate(), a NULL db->pkgcache is not caught, allowing the functions to continue instead of exiting. A later alpm_list_msort() call which uses alpm_list_nth() will thus traverse invalid pointers in a non-existent db->pkgcache->list. pm_errno is set to PM_ERR_MEMORY as _alpm_pkghash_create() will only return NULL when we run out of memory / exceed max hash table size. The local/sync db_populate() functions are also exited. Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Change default sync hash table sizing to 66% fullDan McGee1-2/+2
Since the sync database never changes size once we initialize it, we allow it to be filled a bit more. This reduces the overall memory footprint needed by the hash table. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-02-04Read pkgcache into hashAllan McRae1-4/+9
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>
2011-02-04Get estimated package count when populating databasesDan McGee1-1/+63
This works for both local and sync databases in slightly different ways. For the local database, we can use the directory hard link count on the local/ folder. For sync databases, we use the archive size coupled with some computed average per-package sizes to determine an estimate. This is currently a dead assignment once calculated, but could be used to set the initial size of a hash table.

2011-02-01Fix locale.h/setlocale inclusion with --disable-nlsDan McGee1-1/+0
Noted in FS#22697. When I factored out _alpm_parsedate() into a common function, I didn't move the <locale.h> include properly, causing a build failure when NLS is disabled and this header isn't automatically included everywhere. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-01-25Fix memory leak and error code in DB readingDan McGee1-2/+3
We were returning a package error code rather than a DB one, and we would leak the archive memory if the database file didn't exist. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-22Remove epoch as an independent fieldDan McGee1-9/+0
Instead, go the same route we have always taken with version-release in libalpm and treat it all as one piece of information. Makepkg is the only script that knows about epoch as a distinct value; from there on out we will parse out the components as necessary. This makes the code a lot simpler as far as epoch handling goes. The downside here is that we are tossing some compatibility to the wind; packages using force will have to be rebuilt with an incremented epoch to keep their special status. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-21Add a likely_pkg hint argument to sync_db_readDan McGee1-10/+16
In most (all?) cases, we will process all files for a given sync database entry sequentially. The code currently does an _alpm_pkg_find() for every file in the database, but we had the "current" package readily available. Shift some local variables around a bit to expose this to sync_db_read() and use it if the package is the correct one. On my system, this cuts calls to _alpm_pkg_find() from 20,769 to 10,349 calls during a -Qu operation, and results in a ~30% speedup of the same operation (0.35 sec -> 0.27 sec). This benefit should be apparent anywhere we read in the full contents of the sync databases. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-08Use size_t for alpm_list sizesAllan McRae1-1/+1
There is a lot of swtiching between size_t and int for alpm_list sizes in the codebase. Start converting these to all be size_t by adjusting the return type of alpm_list_count and fixing all additional warnings given by -Wconversion that are generated by this change. Dan: a few more small changes to ensure things compile, adjusting some printf format string characters to accommodate the larger size on x86_64.

2010-12-30Detect undefined PATH_MAXAllan McRae1-0/+1
POSIX does not require PATH_MAX be defined when there is not actual limit to its value. This affects HURD based systems. Work around this by defining PATH_MAX to 4096 (as on Linux) when this is not defined. Also, clean up inclusions of limits.h and remove autoconf check for this header as we do not use macro shields for its inclusion anyway.

2010-12-21Overhaul archive fgets functionDan McGee1-5/+10
The old function was written in a time before we relied on it for nearly every operation. Since then, we have switched to the archive backend and now fast parsing is a big deal. The former function made a per-character call to the libarchive archive_read_data() function, which resulted in some 21 million calls in a typical "load all sync dbs" operation. If we instead do some buffering of our own and read the blocks directly, and then find our newlines from there, we can cut out the multiple layers of overhead and go from archive to parsed data much quicker. Both users of the former function are switched over to the new signature, made easier by the macros now in place in the sync backend parsing code. Performance: for a `pacman -Su` (no upgrades available), _alpm_archive_fgets() goes from being 29% of the total time to 12% The time spent on the libarchive function being called dropped from 24% to 6%. This pushes _alpm_pkg_find back to the title of slowest low-level function. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-21Use macros in sync DB parsingDan McGee1-99/+52
This simplifies a lot of the repetative code and makes it obvious where the tricky or different ones are (e.g. depends, dates). It also makes it significantly easier to change the way this code works in the future. There should be no functional change with this patch. Signed-off-by: Dan McGee <dan@archlinux.org>

2010-12-13Make reading from any file possible in sync DBDan McGee1-12/+8
Whether it be "desc", "depends", or "deltas", it really doesn't matter- treat them all the same and have the ability to read any data from any file in that list. This continues the work in a44c7b8956. Signed-off-by: Dan McGee <dan@archlinux.org>
