2011-06-07Add helper methods for setting directory optionsDan McGee5-63/+64
This keeps duplicate code to a minimum. This will come in more handy as we refactor some of these option setters away. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Use standard errno codes in return from _alpm_archive_fgetsDan McGee3-11/+28
This allows us to not require the context (e.g. handle) when calling this function. Also beef up the checks in the two callers of this function to bail if the last return code is not ARCHIVE_EOF, which is the expected value. This requires a change to one of the pactest return codes and the overall result of the test, but results in a much safer operating condition whereby invalid database entries will stop the operation. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Remove global handle dependencies from sync/upgrade pathsDan McGee7-66/+55
This kills a lot more global handle business off. sync.c still requires the handle declaration for one reference that can't be changed yet; it will be removed in a future patch which isolates all of the necesary API changes. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-03Push down extern handle variable to files that need itDan McGee18-3/+48
This will make the patching process less invasive as we start to remove this variable from all source files. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Add handle attribute to pmpkg_t structDan McGee5-4/+10
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 McGee5-2/+6
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 unnecessary handle != NULL assertsDan McGee2-15/+0
These are simple accessor functions for a struct; the handle never even comes into play when calling these functions. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Remove ALPM_LOG_FUNC macroDan McGee22-252/+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>
2011-06-01lib/dload.c: remove assumption in continuation logicDave Reisner1-5/+3
Callers to curl_download_internal now tell us if its okay to continue a transfer, so obey this instead of using a heuristic. Signed-off-by: Dave Reisner <d@falconindy.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-01dload: abort transfer on CURLOPT_LOW_SPEED_LIMITDave Reisner1-0/+2
If a connection drops below 1kb/s for 10s, curl will kill the transfer and we'll report failure. This is the average transfer speed over the delta defined by CURLOPT_LOW_SPEED_TIME, so setting a low value here shouldn't bother folks using 14.4k dial-up.

2011-05-20Bail early if we don't have a valid lockfile pathDan McGee2-3/+2
This addresses FS#24292. If one does the bad thing of not checking pm_errno after calling set_dbpath(), you may not realize the initialization process went wrong and calling trans_init() resulted in a segfault. If we don't have a lockfile path, bail out and have trans_init() fail. Also remove a ALPM_LOG_FUNC call that was causing pm_errno to return "no handle"; this was due to a log call in the handle setup (whereby the log attempts to use a callback attached to the handle). Signed-off-by: Dan McGee <dan@archlinux.org>

Conflicts: lib/libalpm/trans.c src/pacman/query.c
2011-05-16Fix segfault when uninstalling broken backed-up symlinkDan McGee1-1/+1
Issue FS#24230. If a symlink is broken and included in the removal process of a package, we blew up and segfaulted due to alpm_compute_md5sum() returning NULL and then performing a strcmp() operation. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-16trans.c: create transaction prior to checking DB versionDave Reisner1-9/+10
The addition of the DB version check introduces a lag time between the lockfile creation and the transaction initialization. In cases where the local DB is large enough and/or the user's disk is slow enough, this time is significant enough that its possible for a user to send a SIGINT and leave behind a db.lck file. Signed-off-by: Dave Reisner <d@falconindy.com> 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 McGee2-6/+8
2011-05-05Don't null-check handle lists before settingDan McGee1-6/+10
This needlessly prevents the easiest way available of clearing any of these values. We can also do the same for the 'arch' value. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-05Improve database server APIDan McGee2-23/+88
Currently we have one call that has all sorts of crazy behavior and doesn't make a whole lot of sense. Go from one method to the normal four methods we have for all of our other lists we use in the library to make it a lot easier for a frontend to manipulate server lists. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-05Ensure populate error return codes are consistentDan McGee2-6/+8
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 McGee2-1/+6
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>
2011-05-05dload: ensure we return success if we found files on any mirrorDan McGee1-1/+3
We were erroring out in the case where a first (possibly bogus) mirror would cause the download process to return a failure code, even though subsequent servers had the file. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-05-04Deal with unused function parameters correctlyAllan McRae7-18/+28
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>
2011-05-04Fix warnings reported by -Wwrite-stringsDan McGee1-5/+3
These are places where we stuck a string constant in a variable not marked as const. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-05-04Reduce duplicate signing debug code and fix logic conditionDan McGee1-35/+23
We had a lot of similar looking code that we can collapse down into a function. This also fixes errors seen when turning on some gcc warnings and implicitly casting away the const-ness of the string. Free the list when we are done with it as well. Also, fix a logic error where we should be checking with &&, not ||. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-27Allow conditional compilation with GPGMEDan McGee2-2/+16
This makes it possible to omit usage of -lgpgme, just as we can do for -lcurl and -lcrypto. Thanks to Rémy Oudompheng for an initial stab at this. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24signing: add more detail to unexpected signature count errorDan McGee1-1/+7
Do a quick loop and count of the returned data so we can show how many signatures were parsed and read. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24Enhance GPGME debug outputDan McGee1-11/+97
Add some lookup functions for nice names for the various types used by the library, and remove some fields that are of little use to us in the debug output. This should make looking at key loading and verification a bit easier, especially in determining what makes up our good and bad criteria. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24Perform package verification at package load timeDan McGee4-38/+47
Both md5sum verification and PGP verification can and should be done at package load time. This allows verification to happen as early as possible for packages provided by filename and loaded in the frontend, and moves more stuff out of sync_commit that doesn't really belong there. This should also set the stage for simplified parallel loading of packages later down the road. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24sync_commit: refactor out validate_deltasDan McGee1-50/+53
More stuff going on in the pre-committing stage that can be in a static method to make things a bit more clear. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24sync_commit: refactor out file downloadsDan McGee1-32/+37
This part is almost completely self-contained, except building the list of delta filenames that we use later to check their md5sums. Refactor it into a static method so we can bring most of the code in sync_commit closer to the method name. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-24Rein in the complexity of the signature typeDan McGee7-69/+58
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>
2011-04-24signing: let GPGME handle loading signatures from filesDan McGee5-92/+35
Rather than go through all the hassle of doing this ourselves, just let GPGME handle the work by passing it a file handle. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-23Make dump_pkg_full a little less insaneDan McGee1-2/+2
The various "level" values were a bit crazy to decipher, and we were doing some very interesting comparisons in certain places. Break it out into two parameters instead so we can seperate the type from the extra information display, and do things accordingly. Nothing changes with the display of any of the five types we currently show: -Si, -Sii, -Qi, -Qii, -Qip. Something to note- we should expose the PKG_FROM enum type somehow, this patch leaves the door open to do that quite easily. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-23libalpm/dload: major refactor of signature downloadingDan McGee4-127/+95
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.

2011-04-23libalpm/dload: add allow_resume and reorder error checksDan McGee1-19/+21
The allow_resume is the start of the fix to the "don't ever resume database downloads" problem, as well as being useful for '.sig' downloads as well. For now, we say "always allow resume", but this will eventually get pushed down as necessary. Error checks are reworked in order to correctly error out when a file is not found on the remote end and reports 0 bytes downloaded. In addition, the two error messages printed are now different as one reports a more specific error message provided via the cURL error buffer. Some example output from an -Sy run with [testing], [community], [community2], [eee], and [nonexistant] defined as repos. [community2] and [nonexistant] are both invalid, one using FTP and one using HTTP. :: Synchronizing package databases... testing is up to date community is up to date error: failed retrieving file 'community2.db' from ftp.archlinux.org : Given file does not exist error: failed to update community2 (FTP: couldn't retrieve (RETR failed) the specified file) eee is up to date error: failed retrieving file 'nonexistant.db' from code.toofishes.net : The requested URL returned error: 404 error: failed to update nonexistant (HTTP response code said error) Signed-off-by: Dan McGee <dan@archlinux.org>

2011-04-21sync.c: remove unnecessary check for PM_PGP_VERIFY_UNKNOWNRémy Oudompheng1-7/+0
The value PM_PGP_VERIFY_UNKNOWN is reserved to error cases, now that the signature verification level defaults to the globally set level. The only error case is when handle == NULL, which is false in the context of _alpm_sync_commit(). Signed-off-by: Rémy Oudompheng <remy@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
