do not crash when a meta-data file in the .got directory is empty Reported by Matthias Schmidt ok tb@

got_worktree_open: do not skip a locked worktree When trying to open a worktree from a list of metadata directories (.got, .cvg), error out when a worktree is found but is already locked. Skipping it and proceeding would result in a confusing "no git repository found" error from tog and gotadmin. ok stsp

use a separate .cvg meta data directory for cvg(1) work trees This prevents mixing the use of got and cvg clients in the same work tree. Avoids confusion going forward while cvg differentiates itself further. tog(1) and gotadmin(1) remain compatible with both work tree formats. These tools only read work trees to locate the corresponding repository.

portable: configure: split out dependencies Rather than assume all dependencies are required for all programs, split them out. This will make packaging easier, as well as splitting the code to use subprojects. Note that due to the use of config.h semantics, in most cases the got_compat.h header file is now at the top of the .c file it is included in, so that it can handle the system header inclusion properly.

portable: rework SHA detection Simply the SHA detection by not predicating on libcrypto, but instead checking individual header files.

portable: remove sha1.h; found portably Remove sha1.h as this is found portably across systems.

include sha2.h too where sha1.h is included In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>

add missing check for errors from got_gotconfig_read() in open_worktree()

portable: add back sys/queue.h Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.

using a local packfd variable in open_worktree() is sufficient

move got_opentempfd out of got_repo_open. ok stsp@ thanks for all the help massaging this diff

portable: fix-up sha1.h include -portable doesn't need this directly.

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@

portable: include sha1.h portably Don't directly include sha1.h as this isn't always in the same location across systems.

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@

portable: freebsd: portably include sha1 The SHA implementation is found portably across systems, so don't include sha1.h directly.

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@

portable: make UUID includes generic Move the detection of UUID header files to be included portably. This will have no functional effect until MacOS detection is put in place.

add O_CLOEXEC (close-on-exec) flag to open(2) calls suggested by millert ok thomas_adam

portable: remove queue.h queue.h is included portably, so it shouldn't be included directly.

let gotadmin find the repository automatically if invoked in a work tree Move a small amount of code from worktree.c to a new file worktree_open.c, which contains everything required to open and close a work tree and inspect some of its basic parameters. This can be used by gotadmin. ok tracey
