2011-08-28Refactor signature result return formatDan McGee3-56/+69
I was trying to take a shortcut and not introduce a wrapper struct for the signature results, so packed it all into alpm_sigresult_t in the first iteration. However, this is painful when one wants to add new fields or only return information regarding a single signature. Refactor the type into a few components which are exposed to the end user, and will allow a lot more future flexibility. This also exposes more information regarding the key to the frontend than was previously available. The "private" void *data pointer is used by the library to store the actual key object returned by gpgme; it is typed this way so the frontend has no expectations of what is there, and so we don't have any hard gpgme requirement in our public API.

2011-08-28lib/libalpm/util.c: Fix two memory leaksLukas Fleischer1-0/+2
Free "md5sum" if md5_file() fails in alpm_compute_md5sum(). Free "sha256sum" if sha2_file() fails in alpm_compute_sha256sum(). Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-28Check local database status flag in db_write sanity check blockDan McGee1-5/+1
Do all the checks at once; this also avoids the 'return' call after we have allocated memory for "pkgpath" as well as tweaked the umask. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-28be_sync.c: Fix memory leak in alpm_db_update()Lukas Fleischer1-0/+2
Free "syncpath" and restore umask if we fail to grab a lock. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-28Fix possible mismatched type with several curl argumentsDan McGee1-2/+4
After commit 2e7d0023150664, we use off_t rather than long variables. Use the _LARGE variants of the methods to indicate we are passing off_t sized variables, and cast using (curl_off_t) accordingly. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-25Always process validity value returned by gpgmeDan McGee1-21/+16
Don't force 'never'; you should be checking both the status and validity anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-25strtrim: don't move empty stringDan McGee1-1/+6
There were many cases where the string coming in was a blank line, e.g. "\n\0", length 1. The trim routine starts by trimming leading spaces, thus trimming everything. We would then proceed to do a memmove of the NULL byte, which is completely worthless as we can just assign it instead. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-25Remove argument from check_pgp_helperDan McGee4-10/+6
This one wasn't all that necessary as we only used it in one place in the function, which can be checked easily enough at the call site. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-25Remove trans is NULL check in QUESTION/EVENT/PROGRESS macrosDan McGee1-3/+3
trans cannot (and better not) be NULL at any point when these are being called. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-25Finish large file download attack preventionDan McGee1-3/+20
This handles the no Content-Length header problem as stated in the comments of FS#23413. We add a quick check to the callback that will force an abort if the downloaded data exceeds the payload size, and then check for this error in the post-download cleanup code. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-25Use off_t rather than double where possibleDan McGee2-11/+11
Beautiful of libcurl to use floating point types for what are never fractional values. We can do better, and we usually want these values in their integer form anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-24Improved alpm_list_mmerge() performance (fixed coding style)Diogo Sousa1-10/+15
Improved alpm_list_mmerge() performance by removing an extra pass to obtain the tail node. This was actually suggested by a TODO comment. Signed-off-by: Diogo Sousa <diogogsousa@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-23vercmp: ensure 2.0a and 2.0.a do not compare equalDan McGee1-2/+7
We had this interesting set of facts conundrum, according to vercmp return values: 2.0a < 2.0 2.0 < 2.0.a 2.0a == 2.0.a This introduces a code change that ensures '2.0a < 2.0.a' as would be expected by the first two comparisons. Unfortunately this stays us a bit further from upstream RPM code, but those are the breaks (in RPM, the versions involving 'a' do in fact compare the same, but they are both greater than the bare '2.0'). Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-23Style-match rpmvercmp code with upstreamDan McGee1-9/+9
Not sure how or why some of this differed, but it is easy enough to set it back to how it was so it is easier to diff. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-22dload: prevent need to copy struct in mask_signal()Dan McGee1-7/+6
Since we store this directly in the download function, just rework mask_signal() to take a pointer to a location to store the original. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-22dload: add open_mode to payload structDave Reisner2-4/+6
This is a precursor to a following patch which will move the setting of options to a separate function. With the open mode as part of the struct, we can avoid modifying stack allocated variables. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-22dload: rename cd_filename to content_disp_nameDave Reisner2-5/+5
This is more in line with the menagerie of file name members that we now have on the payload struct. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-22dload: move tempfile and destfile to payload structDave Reisner2-26/+31
These are private to the download operation already, so glob them onto the struct. This is an ugly rename patch, with the only logical change being that destfile and tempfile are now freed by the payload_free function.

2011-08-19dload: rename payload->filename to payload->remote_nameDave Reisner3-17/+17
This is a far more accurate description of what this is, since it's more than likely not really a filename at all, but the name after a final slash on a URL. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-19Rework finding a writable cache directoryDan McGee1-15/+29
This is a refactor and refresh of the code used to find where we should download packages. * Incorporate suggestions from FS#25435 to use TMPDIR from the environment if set, otherwise fall back to /tmp as before. * Make the writability tests a bit more in depth. We now do a three part check consisting of: - S_ISDIR(): is this even a directory - access(W_OK): is this directory writable by the current user. Unfortunately for root, this almost always returns that it is, but in the case of a RO mount or NFS share inaccessible to root, this check will exclude the directory. - mode & (any write bit): is there a writable bit set on this directory. This makes it possible to enforce a read-only cache directory by setting permissions to 0555, for example. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-19Be more robust when copying package dataDan McGee8-25/+74
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>
2011-08-19lib/dload: unlink on response code >=400Dave Reisner1-1/+7

2011-08-19dload: add 'unlink_on_fail' to payload structDave Reisner3-5/+5
Let callers of _alpm_download state whether we should delete on fail, rather than inferring it from context. We still override this decision and always unlink when a temp file is used. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-18Convert resolvedep() to use _alpm_depcmp_literal()Dan McGee1-5/+10
The whole first loop is trying to check literals only, so teach it to do so. Also, reorder operations to make more sense by putting the strcmp() first in the literal loop, and using a very cheap name_hash check first in the second loop. 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>
2011-08-18Add an _alpm_depcmp_literal() functionDan McGee2-10/+14
This omits the finding of matching provisions and only checks the package itself against the provided dep. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-18Remove use of no-op accessor functions in libraryDan McGee8-44/+36
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 McGee6-25/+76
* 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.

2011-08-17lib/dload: refactor deletion on failureDave Reisner1-6/+2
This moves all the delete-on-fail logic to under cleanup label. This also implies should_unlink when a payload is received that doesn't allow resuming.

2011-08-17Avoid stat() on NULL path in curl_download_internal()Lukas Fleischer1-1/+1
stat()'s behaviour is undefined if the first argument is NULL and might be prone to segfault. Add an additional check to skip the stat() invocation if no destfile is used. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de> Signed-off-by: Dan McGee <dan@archlinux.org>
