The hope is that existing + users will not mind this change, and eventually the warning can be + turned into a hard error, upgrading the deprecation into removal of + this (mis)feature. That is not scheduled to happen in the upcoming + release (yet). + + * The historical argument order "git merge <msg> HEAD <commit>..." + has been deprecated for quite some time, and will be removed in a + future release. + + +Updates since v2.12 +------------------- + +UI, Workflows & Features + + * "git describe" and "git name-rev" have been taught to take more + than one refname patterns to restrict the set of refs to base their + naming output on, and also learned to take negative patterns to + name refs not to be used for naming via their "--exclude" option. + + * Deletion of a branch "foo/bar" could remove .git/refs/heads/foo + once there no longer is any other branch whose name begins with + "foo/", but we didn't do so so far. Now we do. + + * When "git merge" detects a path that is renamed in one history + while the other history deleted (or modified) it, it now reports + both paths to help the user understand what is going on in the two + histories being merged. + + * The <url> part in "http.<url>.<variable>" configuration variable + can now be spelled with '*' that serves as wildcard. + E.g. "http.https://*.example.com.proxy" can be used to specify the + proxy used for https://a.example.com, https://b.example.com, etc., + i.e. any host in the example.com domain. + + * "git tag" did not leave useful message when adding a new entry to + reflog; this was left unnoticed for a long time because refs/tags/* + doesn't keep reflog by default. + + * The "negative" pathspec feature was somewhat more cumbersome to use + than necessary in that its short-hand used "!" which needed to be + escaped from shells, and it required "exclude from what?" specified. + + * The command line options for ssh invocation needs to be tweaked for + some implementations of SSH (e.g. PuTTY plink wants "-P <port>" + while OpenSSH wants "-p <port>" to specify port to connect to), and + the variant was guessed when GIT_SSH environment variable is used + to specify it. The logic to guess now applies to the command + specified by the newer GIT_SSH_COMMAND and also core.sshcommand + configuration variable, and comes with an escape hatch for users to + deal with misdetected cases. + + * The "--git-path", "--git-common-dir", and "--shared-index-path" + options of "git rev-parse" did not produce usable output. They are + now updated to show the path to the correct file, relative to where + the caller is. + + * "git diff -W" has been taught to handle the case where a new + function is added at the end of the file better. + + * "git update-ref -d" and other operations to delete references did + not leave any entry in HEAD's reflog when the reference being + deleted was the current branch. This is not a problem in practice + because you do not want to delete the branch you are currently on, + but caused renaming of the current branch to something else not to + be logged in a useful way. + + +Performance, Internal Implementation, Development Support etc. + + * The code to list branches in "git branch" has been consolidated + with the more generic ref-filter API. + + * Resource usage while enumerating refs from alternate object store + has been optimized to help receiving end of "push" that hosts a + repository with many "forks". + + * The gitattributes machinery is being taught to work better in a + multi-threaded environment. + + * "git rebase -i" starts using the recently updated "sequencer" code. + + * Code and design clean-up for the refs API. + + * The preload-index code has been taught not to bother with the index + entries that are paths that are not checked out by "sparse checkout". + + * Some warning() messages from "git clean" were updated to show the + errno from failed system calls. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.12 +----------------- + +Unless otherwise noted, all the fixes since v2.9 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * "git repack --depth=<n>" for a long time busted the specified depth + when reusing delta from existing packs. This has been corrected. + (merge 42b766d765 jk/delta-chain-limit later to maint). + + * The code to parse the command line "git grep <patterns>... <rev> + [[--] <pathspec>...]" has been cleaned up, and a handful of bugs + have been fixed (e.g. we used to check "--" if it is a rev). + (merge 131f3c96d2 jk/grep-no-index-fix later to maint). + + * "git ls-remote" and "git archive --remote" are designed to work + without being in a directory under Git's control. However, recent + updates revealed that we randomly look into a directory called + .git/ without actually doing necessary set-up when working in a + repository. Stop doing so. + (merge 4b0c3c7735 jn/remote-helpers-with-git-dir later to maint). + + * "git show-branch" expected there were only very short branch names + in the repository and used a fixed-length buffer to hold them + without checking for overflow. + (merge d3cc5f4c44 jk/show-branch-lift-name-len-limit later to maint). + + * A caller of tempfile API that uses stdio interface to write to + files may ignore errors while writing, which is detected when + tempfile is closed (with a call to ferror()). By that time, the + original errno that may have told us what went wrong is likely to + be long gone and was overwritten by an irrelevant value. + close_tempfile() now resets errno to EIO to make errno at least + predictable. + (merge 7e8c9355b7 jk/tempfile-ferror-fclose-confusion later to maint). + + * "git remote rm X", when a branch has remote X configured as the + value of its branch.*.remote, tried to remove branch.*.remote and + branch.*.merge and failed if either is unset. + (merge 20690b2139 rl/remote-allow-missing-branch-name-merge later to maint). + + * A "gc.log" file left by a backgrounded "gc --auto" disables further + automatic gc; it has been taught to run at least once a day (by + default) by ignoring a stale "gc.log" file that is too old. + (merge a831c06a2b dt/gc-ignore-old-gc-logs later to maint). + + * Other minor doc, test and build updates and code cleanups. + (merge 2cfa83574c mm/two-more-xstrfmt later to maint). |
