read_gitconfig: fix GOT_IGNORE_GITCONFIG case
set gitconfig_remotes to NULL to avoid a double-free, and reset the global author name/email fields too. ok stsp@
got_repo_pack_fds_close: don't close(0)
got_repo_pack_fds_close will try to close all of the GOT_PACK_NUM_TEMPFILES fds, even the ones that didn't manage to get a value from got_opentempfd(), which would result in a close(0) if we do not initialize to -1 here.
Make sure got_repo_pack_fds_close() frees a malloc'ed pointer.
Found by llvm's scan-build (bad free). OK stsp
Don't chug along if repo format version is unsupported.
Found by llvm's scan-build (dead store). OK stsp
move got_opentempfd out of got_repo_open. ok stsp@
thanks for all the help massaging this diff
properly swap cached struct pack array elements in got_repo_cache_pack()
Avoids clobbering open files for delta base/accumulation, leaking file descriptors, and triggering errors from close(2) during got_repo_close() as we try to close the same file descriptor more than once.
open temporary files needed for delta application in got_repo_open()
This prepares for callers of got_repo_open() that cannot afford to open files in /tmp, such as gotwebd. In a follow-up change, we could ask such callers to pass in the required amount of open temporary files. One consequence is that got_repo_open() now requires the "cpath" pledge promise. Add the "cpath" promise to affected callers and remove it once the repository has been opened. ok tracey
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@
don't `goto done' if calloc fails
otherwise we call got_repo_close with repo being NULL and segfault there. ok stsp
cache a list of known pack index files when the repository is opened
Avoids overhead due to readdir calls while searching a pack index. ok op@
make got_repo_match_object_id_prefix() reject overlong input strings
suggested by + ok naddy
handle reference arguments which look like short object IDs
Match command line arguments against references before matching object IDs. This makes it possible to use reference names that happen to match a short object ID. For example, a branch called "11ac" could not be diffed in OpenBSD src.git which happens to contain commit IDs that begin with hex digits 0x11ac. A bogus error would be reported in this situation: $ got diff master 11ac got: ambiguous object ID ok naddy
factorize imsg_clear calls after imsg_flush failures
imsg_clear frees and closes resources allocated as part of enqueueing imsgs so it's a no-op after reads. discussed with and ok stsp@
reuse existing deltas when creating pack files
