2017-09-13libmakepkg: check for invalid tags in gitEli Schwartz1-1/+10
As per https://lists.archlinux.org/pipermail/arch-general/2017-July/043876.html git doesn't check that the tag name matches what an annotated tag object *thinks* it should be called. This is a bit of a theoretical attack and some would argue that we should always use commits since upstream can legitimately change a tag, but nevertheless this can result in a downgrade attack if the git download transport was manipulated or the upstream repository hacked. So, check the tag blob to make sure the tag actually matches the name we used for `git checkout`. This really should be fixed in git itself, rather than forcing all downstream users of git verify-tag to implement their own checks, but the git developers disagree, see the discussion surrounding https://public-inbox.org/git/xmqqk2hzldx8.fsf@gitster.mtv.corp.google.com/ Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2017-07-06libmakepkg: fix unsanitized source filenamesEli Schwartz1-2/+2
There were a couple places where filenames beginning with "-" were not properly guarded against by passing them after "--". Some PKGBUILD authors are crazy, but we still take those into account. Signed-off-by: Eli Schwartz <eschwartz93@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2017-01-04makepkg: Verify git signaturesEli Schwartz1-8/+3
A git repository is marked as signed if it contains the query "signed" as defined by https://tools.ietf.org/html/rfc3986 Adds two utility functions in util/source.sh.in to extract fragments and queries, and modifies source/git.sh.in to use them.

2015-12-15makepkg: Output full URL in case of download failureFlorian Pritz1-1/+1
Most entries in $sources contain variables so finding out why a URL fails to download is hard because one has to manually replace the variables when looking at the PKGBUILD. Simply output the full URL here so that it can be easily seen what is wrong. Old: ==> ERROR: Failure while downloading example-1.2.4.tar.gz New: ==> ERROR: Failure while downloading http://example.org/releases/1.1/example-1.2.4.tar.gz With the new format it is much more obvious that the directory name is the culprint (1.1 vs 1.2) while the old one would not display that information.
