use mkstemps(3) instead of mkstemp(3) for opening named temporary files
Allows 'got commit' to use a ".diff" suffix for temporary diff files. ok op@
don't create signed tag objects with trailing NUL
Although Git itself did not care, the superfluous NUL at the end of the tag object was breaking GitHub's SSH signature detection. ok stsp@
fix snprintf error handling
follow the "proper secure idiom" described in the CAVEATS section of printf(3). reminded by tb@ and millert@
Prevent memory leak when asprintf fails.
Found by llvm's scan-build. OK stsp
fix pipe usage for linux
This uses the correct read and write ends of the fds returned by pipe(2) on linux. It also moves away from creating FILE* streams with fdopen and reading the stream with buf_load (which performs a fstat, and breaks due to a zero length file size on linux) by instead reading from the fd itself. Reported by abieber@, with assistance from stsp@ ok stsp@
fix tag signing when the key file does not exist
This should fail without creating any tag. Before, ssh-keygen(1) would print an error to stderr, but got would create an unsigned tag. ok op@
create and verify tags signed by SSH keys
This adds a new -s flag to 'got tag' that specifies the signer identity (for example, a key file) of the tagger. The tag object will include a signature that validates each of the tag object headers and the tag message. Verifying these signed tags requires maintaining an allowed signers file which maps signer identities (i.e. the email address of the tagger) to SSH public keys. See ssh-keygen(1) for more details of the allowed signers file. After creating this file and providing the path to it in got.conf(5) using the allowed_signers option, tags may be verified using with 'got tag -V tag_name'. The return code will be non-zero if a signature fails to verify. ok stsp@
build with -Wmissing-prototypes

inline struct got_object_id in struct got_object_qid
Saves us from doing a malloc/free call for every item on the list. ok op@
add O_CLOEXEC (close-on-exec) flag to open(2) calls
suggested by millert ok thomas_adam
for portability, handle errno variations upon open(2) failure with O_NOFOLLOW
Problem pointed out by naddy for FreeBSD -portable. Discussed with millert, thomas adam, and naddy.
add a 'got merge' command for creating merge commits
Additional testing by Thomas Adam. ok tracey
