fix a race in gotd notification processing Dequeue notifications from the list only once the notify process has confirmed that the notification has been sent. This should be more robust for the following reason: In some spots were are checking the list head against NULL to see if any notifications are still pending. By removing notifications from this list too early, this check did not cover notifications which were still in flight. We could thus end up deciding to shut down the session process too early, and the last notification of several would fail. Issue observed when sending a new commit on a branch and a new tag which tags this commit to gotd in a single 'got send' operation. Only the tag notification would make it, while the other notification never arrived after an 'unexpected EOF' error in the notify process while trying to send a confirmation to the session process. ok op@

fix bogus "unexpected privsep message" from gotsh during "got send" Ensure that gotsh receives its end of the pack file data pipe before repo_write starts sending pack file status messages. Messages of type GOTD_IMSG_PACKFILE_StATUS would end up being received in gotsh's serve_write() function too early. This race is similar to the one fixed for repo_read back in commit c2274a511a7415078e2628f969b8459f69432411 Reported by martijn@, who pin-pointed the problematic case in the code, thanks!

fix default access for root and _gotd when gotsysd runs without config file

gotwebd: do not forget to initialize *ngroups argument for getgrouplist() spotted by Denis Bodor, thanks!

whitespace fix; spotted by op@

improve redundant pack detection during cleanup Instead of storing all referenced object IDs in a set, use the pack index of the large pack file we have created to check whether an object exists. Apply the modification time check only to packs which contain unreferenced objects. Otherwise we can leave many duplicate pack files behind. I observed this when all refs were packed and the packed-refs file was days old. ok op@

use got_path_cmp() instead of strcmp() in pack_info_cmp() ok op@

when packing, do not forget to mark commits reached via tags as traversed ok op@

ignore arbitrary amounts of leading slashes in ignore patterns, not just one

tweak 'got status' and 'got add' ignores handling for better git compatibility Skip past leading slashes in ignore patterns. In gitignore(7), these trigger the behavior got has by default. Add regress test. Lift documentation of ignore patterns to a subsection, referenced by the `add` and `status` docs. Refine documentation of ignore patterns to discuss the extensions to glob(7) as a whole, and then list caveats relative to git(1) and cvs(1). Add a file to the test worktree in the main gitignore regress test in order to register a known delta to gitignore(7) that was ambiguously documented previously: for the pattern a/**/foo, git will ignore a/foo, but got will not.

gotwebd: delete trailing whitespaces

gotwebd: simplify handling of action not found

bump version number

CHANGES for 0.112

stop opening the repository when opening a work tree Opening a bunch of files in /tmp for pack temp files and opening the repository just to validate the work tree's base-commit ID is overkill. Simply parse the ID directly. If the commit object no longer exists we will run into another error sooner or later. The commit is already protected by the work tree reference. If it is missing then something has badly gone wrong. Doing less work when opening work trees speeds up 'got status' a bit. As pointed out by Kyle this also avoids running got-read-gitconfig twice when opening both a repository and a work tree. ok by op@ and Kyle Ackerman

add comments explaining that .got/base-commit needs hash algo information Hopefully, if we ever bump the work tree format in the future we will see these comments and sneak in a change to the .got/base-commit file in order to record the hash algorithm of the base commit ID.

Plug memory leaks in some libexecs This occurred when these particular libexecs get an imsg of type GOT_IMSG_STOP. They attempt to exit the main loop and leak the last imsg they received. ok stsp@ op@

Plug a memory leak in gitconfig.c conf_parse_line frees *section before allocating a new one, which leaks *section on the last iteration of conf_parse. ok stsp@

remove a gotsysd todo item that is done

implement support for protected references in gotsys.conf and gotsysd

gotsysd: call gotsys_conf_clear() in sysconf_shutdown() before exiting

fix unrelated errors being reported if a histedit operation is aborted This avoids errors such as "object not found" or "reference not found" when exiting the histedit script editor without making any changes to the script. got_worktree_histedit_abort() was filling up error.c error buffers with unrelated errors that were simply being ignored. I now see the expected "no changes made to histedit script" error. Issue reported by ninjin on IRC

add a test for behaviour around .gitignore files within sub-directories

gotwebd: inherit all user groups Required if repos_path is not owned by the _gotwebd group. ok stsp@
