2011-08-08Attempt to fix up some of the brokenness around failed package loadsDan McGee1-16/+16
This is a bit of a mess, due to the fact that we have a progress meter running. It is also ironic that we are in the midst of a method named "commit" when we haven't done a damn thing yet, and can still fail hard if either a checksum or signature is invalid or unrecognized. Adapt the former test_md5sum method to be invoked for any of the various failure types, which at least gives the user some indication of what packages are failing. A second patch will be needed to actually show worthwhile error codes, but this is going to involve modifying the actual data passed with the callback. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-05lib/dload: prevent large file attacksDave Reisner1-14/+23
This means creating a new struct which can pass more descriptive data from the back end sync functions to the downloader. In particular, we're interested in the download size read from the sync DB. When the remote server reports a size larger than this (via a content-length header), abort the transfer. In cases where the size is unknown, we set a hard upper limit of: * 25MiB for a sync DB * 16KiB for a signature For reference, 25MiB is more than twice the size of all of the current binary repos (with files) combined, and 16KiB is a truly gargantuan signature.

2011-07-05dload: handle irregular URLsDave Reisner1-1/+1
URLs might end with a slash and follow redirects, or could be a generated by a script such as /getpkg.php?id=12345. In both cases, we may have a better filename that we can write to, taken from either content-disposition header, or the effective URL. Specific to the first case, we write to a temporary file of the format 'alpmtmp.XXXXXX', where XXXXXX is randomized by mkstemp(3). Since this is a randomly generated file, we cannot support resuming and the file is unlinked in the event of an interrupt. We also run into the possibility of changing out the filename from under alpm on a -U operation, so callers of _alpm_download can optionally pass a pointer to a *char to be filled in by curl_download_internal with the actual filename we wrote to. Any sync operation will pass a NULL pointer here, as we rely on specific names for packages from a mirror. Fixes FS#22645. Signed-off-by: Dave Reisner <d@falconindy.com>
2011-07-05Allow invalid sync DBs to be returned by the libraryDan McGee1-0/+8
They are placeholders, but important for things like trying to re-sync a database missing a signature. By using the alpm_db_validity() method at the right time, a client can take the appropriate action with these invalid databases as necessary. In pacman's case, we disallow just about anything that involves looking at a sync database outside of an '-Sy' operation (although we do check the validity immediately after). A few operations are still permitted- '-Q' ops that don't touch sync databases as well as '-R'. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05signing: move to new signing verification and return schemeDan McGee1-3/+3
This gives us more granularity than the former Never/Optional/Always trifecta. The frontend still uses these values temporarily but that will be changed in a future patch. * Use 'siglevel' consistenly in method names, 'level' as variable name * The level becomes an enum bitmask value for flexibility * Signature check methods now return a array of status codes rather than a simple integer success/failure value. This allows callers to determine whether things such as an unknown signature are valid. * Specific signature error codes mostly disappear in favor of the above returned status code; pm_errno is now set only to PKG_INVALID_SIG or DB_INVALID_SIG as appropriate.

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-3/+4
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field.

2011-06-03Remove global handle dependencies from sync/upgrade pathsDan McGee1-20/+18
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>

2011-06-03Remove ALPM_LOG_FUNC macroDan McGee1-6/+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>
2011-05-05dload: 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>
2011-04-24Perform package verification at package load timeDan McGee1-29/+11
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 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 McGee1-2/+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>
2011-04-22libalpm/dload: major refactor of signature downloadingDan McGee1-3/+22
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.

2011-04-21sync.c: remove unnecessary check for PM_PGP_VERIFY_UNKNOWNRémy Oudompheng1-7/+0
