Save it to a file in $GIT_DIR and show it next time the "gc + --auto" is run. + + * The submodule code has been taught to work better with separate + work trees created via "git worktree add". + + * "git gc" is safe to run anytime only because it has the built-in + grace period to protect young objects. In order to run with no + grace period, the user must make sure that the repository is + quiescent. + + * A recent "filter-branch --msg-filter" broke skipping of the commit + object header, which is fixed. + + * The normalize_ceiling_entry() function does not muck with the end + of the path it accepts, and the real world callers do rely on that, + but a test insisted that the function drops a trailing slash. + + * A test for interaction between untracked cache and sparse checkout + added in Git 2.5 days were flaky. + + * A couple of commands still showed "[options]" in their usage string + to note where options should come on their command line, but we + spell that "[<options>]" in most places these days. + + * The synopsis text and the usage string of subcommands that read + list of things from the standard input are often shown as if they + only take input from a file on a filesystem, which was misleading. + + * "git am -3" had a small regression where it is aborted in its error + handling codepath when underlying merge-recursive failed in certain + ways, as it assumed that the internal call to merge-recursive will + never die, which is not the case (yet). + + * The linkage order of libraries was wrong in places around libcurl. + + * The name-hash subsystem that is used to cope with case insensitive + filesystems keeps track of directories and their on-filesystem + cases for all the paths in the index by holding a pointer to a + randomly chosen cache entry that is inside the directory (for its + ce->ce_name component). This pointer was not updated even when the + cache entry was removed from the index, leading to use after free. + This was fixed by recording the path for each directory instead of + borrowing cache entries and restructuring the API somewhat. + + * "git merge-file" tried to signal how many conflicts it found, which + obviously would not work well when there are too many of them. + + * The error message from "git blame --contents --reverse" incorrectly + talked about "--contents --children". + + * "git imap-send" did not compile well with older version of cURL library. + + * Merging a branch that removes a path and another that changes the + mode bits on the same path should have conflicted at the path, but + it didn't and silently favoured the removal. + + * "git --literal-pathspecs add -u/-A" without any command line + argument misbehaved ever since Git 2.0. + + * "git daemon" uses "run_command()" without "finish_command()", so it + needs to release resources itself, which it forgot to do. + + * "git status --branch --short" accessed beyond the constant string + "HEAD", which has been corrected. + + * We peek objects from submodule's object store by linking it to the + list of alternate object databases, but the code to do so forgot to + correctly initialize the list. + + * The code to prepare the working tree side of temporary directory + for the "dir-diff" feature forgot that symbolic links need not be + copied (or symlinked) to the temporary area, as the code already + special cases and overwrites them. Besides, it was wrong to try + computing the object name of the target of symbolic link, which may + not even exist or may be a directory. + + * A Range: request can be responded with a full response and when + asked properly libcurl knows how to strip the result down to the + requested range. However, we were hand-crafting a range request + and it did not kick in. + + * Having a leftover .idx file without corresponding .pack file in + the repository hurts performance; "git gc" learned to prune them. + + * Apple's common crypto implementation of SHA1_Update() does not take + more than 4GB at a time, and we now have a compile-time workaround + for it. + + * Produce correct "dirty" marker for shell prompts, even when we + are on an orphan or an unborn branch. + + * A build without NO_IPv6 used to use gethostbyname() when guessing + user's hostname, instead of getaddrinfo() that is used in other + codepaths in such a build. + + * The exit code of git-fsck did not reflect some types of errors + found in packed objects, which has been corrected. + + * The helper used to iterate over loose object directories to prune + stale objects did not closedir() immediately when it is done with a + directory--a callback such as the one used for "git prune" may want + to do rmdir(), but it would fail on open directory on platforms + such as WinXP. + + * "git p4" used to import Perforce CLs that touch only paths outside + the client spec as empty commits. It has been corrected to ignore + them instead, with a new configuration git-p4.keepEmptyCommits as a + backward compatibility knob. + + * The completion script (in contrib/) used to list "git column" + (which is not an end-user facing command) as one of the choices + (merge 160fcdb sg/completion-no-column later to maint). + + * The error reporting from "git send-email", when SMTP TLS fails, has + been improved. + (merge 9d60524 jk/send-email-ssl-errors later to maint). + + * When getpwuid() on the system returned NULL (e.g. the user is not + in the /etc/passwd file or other uid-to-name mappings), the + codepath to find who the user is to record it in the reflog barfed + and died. Loosen the check in this codepath, which already accepts + questionable ident string (e.g. host part of the e-mail address is + obviously bogus), and in general when we operate fmt_ident() function + in non-strict mode. + (merge 92bcbb9 jk/ident-loosen-getpwuid later to maint). + + * "git symbolic-ref" forgot to report a failure with its exit status. + (merge f91b273 jk/symbolic-ref-maint later to maint). + + * History traversal with "git log --source" that starts with an + annotated tag failed to report the tag as "source", due to an + old regression in the command line parser back in v2.2 days. + (merge 728350b jk/pending-keep-tag-name later to maint). + + * "git p4" when interacting with multiple depots at the same time + used to incorrectly drop changes. + + * Code clean-up, minor fixes etc. |
