2011-08-19Be more robust when copying package dataDan McGee1-1/+5
This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-18Fix replacement of provider issueDan McGee1-1/+2
When we switched to using alpm_depcmp() in resolving replacments, we had some interesting behavior with regard to providers and packages not found in repositories. Teach the replacement resolving code to not look at provisions at all to be slightly more sane. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-18Remove use of no-op accessor functions in libraryDan McGee1-7/+6
The functions alpm_db_get_name(), alpm_pkg_get_name(), and alpm_pkg_get_version() are not necessary at all, so remove the calling and indirection when used in the backend, which makes things slightly more efficient and reduces code size. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Enhance and utilize database status flagsDan McGee1-1/+4
* Move is_local standalone field to status enum * Create VALID/INVALID flag pair * Create EXISTS/MISSING flag pair With these additional fields, we can be more intelligent with database loading and messages to the user. We now only warn once if a sync database does not exist and do not continue to try to load it once we have marked it as missing. The reason for the flags existing in pairs is so the unknown case can be represented. There should never be a time when both flags in the same group are true, but if they are both false, it represents the unknown case. Care is taken to always manipulate both flags at the same time.

2011-08-17dload: zero out pm_errno in curl_download_internalDave Reisner1-10/+3
This reverts some hacky behavior from 5fc3ec and resets the handle's pm_errno where it should be reset -- prior to each download. This prevents a transaction with a download from being aborted when a package is successfully grabbed from a secondary server.

2011-08-15lib/sync: ignore download errors for as long as possibleDave Reisner1-11/+13
Previously, the behavior was such that if a sync operation required packages from multiple repos, a download error in the first repo would cause a hard repo, ignoring the remainder of the repositories. Change this behavior so that we do a better job of fetching as many packages as possible before aborting the transaction. There's a little bit of refactoring mixed in here to get rid of some useless variables. Since we now depend heavily on the value of handle->pm_errno being accurate the determine the function's return value, we clear it when the transaction state is set. Fixes FS#25532.

2011-08-15Further fixes to replacement iterationDan McGee1-10/+4
A partial fix for this was in commit 7de92cb22, but this should fix the remaining cases. There are still several issues dealing with "provision as replacement" selection however. Addresses FS#25538 and FS#25527. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Parse conflicts/provides/replaces at database load timeDan McGee1-5/+2
We did this with depends way back in commit c244cfecf654d3 in 2007. We can do it with these fields as well. Of note is the inclusion of provides even though only '=' is supported- we'll parse other things, but no guarantees are given as to behavior, which is more or less similar to before since we only looked for the equals sign. Also of note is the non-inclusion of optdepends; this will likely be resolved down the road. The biggest benefactors of this change will be the resolving code that formerly had to parse and reparse several of these fields; it only happens once now at load time. This does lead to the disadvantage that we will now always be parsing this information up front even if we never need it in the split form, but as these are uncommon fields and our parser is quite efficient it shouldn't be a big concern.

2011-08-09Parse replaces strings as dep strings with version specsDan McGee1-10/+17

2011-08-09Attempt 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>

2011-07-06lib/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. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2011-07-06dload: 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.
