2011-07-05lib/dload: prevent large file attacksDave Reisner
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 Reisner
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>

2011-07-05parse_options: accept multiple argumentsAllan McRae
Allow command-line options to accept multiple arguments without additional quoting by taking the list of arguments until one starting with a "-" is reached. The only current use of this is the --pkg option in makepkg. This allows (e.g.) makepkg --pkg foo bar and packages "foo" and "bar" will be built.

2011-07-05parse_options: implement optional argumentsAllan McRae
This allows options specified with a trailing "::" to optionally take arguments. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-05Simplify alpm_list_previousAllan McRae
We can readily detect the first node in a list by checking if node->prev->next is NULL. So there is no need to pass the head of the list to this function and its prototype now looks like all the other item accessors.

2011-07-05Remove alpm_list_firstAllan McRae
The only thing this accessor did was remove the const qualifier given our entire list implementation requires passing around the head anyway. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Allow invalid sync DBs to be returned by the libraryDan McGee
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>
2011-07-05Allow frontend access to signature verification informationDan McGee
Show output in -Qip for each package signature, which includes the UID string from the key ("Joe User <joe@example.com>") and the validity of said key. Example output: Signatures : Valid signature from "Dan McGee <dpmcgee@gmail.com>" Unknown signature from "<Key Unknown>" Invalid signature from "Dan McGee <dpmcgee@gmail.com>" Also add a backend alpm_sigresult_cleanup() function since memory allocation took place on this object, and we need some way of freeing it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Correctly check the GPG error codesDan McGee
The error code is in fact a bitmask value of an error code and an error source, so use the proper function to get only the relevant bits. For the no error case, this shouldn't ever matter, but it bit me when I was trying to compare the error code to other values and wondered why it wasn't working, so set a good example. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05signing: move to new signing verification and return schemeDan McGee
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.

2011-07-03diskspace: remove all libarchive usageDan McGee
Now that the filelists capture mode and size information, we can read the data from there and prevent having to loop through and uncompress every archive to check required diskspace usage. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-03Move alpm filelists to a struct objectDan McGee
This allows us to capture size and mode data when building filelists from package files. Future patches will take advantage of this newly available information, and frontends can use it as well. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-07-03be_sync: make READ_NEXT() a no-arg macroDan McGee
We passed in 'line', but not 'buf.line'. In addition, the macros building off of READ_NEXT() assume variable names anyway. Since we only use these macros in one function, might as well simplify them. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-30pactest: remove no longer necessary newline hacksDan McGee

2011-06-30pactest: create packages in memoryDan McGee
This is similar to what was just done for the sync databases. Move a few pieces around so we never need to actually write out the filesystem to create a package, and simply stream the tarfile out from the data we've collected. Once again, a few newline addition hacks and other things have to be left in place in order not to break everything; this time however most of the assumptions are in pactest and not libalpm. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-30Make local_db_read() private to the local backendDan McGee
There is little need to expose the guts of this function even within the library. Make it static in be_local.c, and clean up a few other things since we know exactly where it is being called from: * Remove unnecessary origin checks in _cache_get_*() methods- if you are calling a cache method your package type will be correct. * Remove sanity checks within local_db_read() itself- packages will always have a name and version if they get this far, and the package object will never be NULL either. The one case calling this from outside the backend was in add.c, where we forced a full load of a package before we duplicated it. Move this concern elsewhere and have pkg_dup() always force a full package load via a new force_load() function on the operations callback struct. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-30Fix a few warnings pointed out via clang scan-buildDan McGee
Some of these are legit (the backup hash NULL checks), while others are either extemely unlikely or just impossible for the static code analysis to prove, but are worth adding anyway because they have little overhead. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-30fix vim syntax highlighting of .sh filesFlorian Pritz
vim recognises what type of shell script it's dealing with by looking at the shebang. If detection fails it falls back to sh which doesn't support some bash features. Adding a normal, possibly broken, shebang which gets fixed by the Makefile allows vim to detect bash syntax.
