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 is now removed. + + * The default location "~/.git-credential-cache/socket" for the + socket used to communicate with the credential-cache daemon has + been moved to "~/.cache/git/credential/socket". + + * Git now avoids blindly falling back to ".git" when the setup + sequence said we are _not_ in Git repository. A corner case that + happens to work right now may be broken by a call to die("BUG"). + We've tried hard to locate such cases and fixed them, but there + might still be cases that need to be addressed--bug reports are + greatly appreciated. + + +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. + + * "Cc:" on the trailer part does not have to conform to RFC strictly, + unlike in the e-mail header. "git send-email" has been updated to + ignore anything after '>' when picking addresses, to allow non-address + cruft like " # stable 4.4" after the address. + + * When "git submodule init" decides that the submodule in the working + tree is its upstream, it now gives a warning as it is not a very + common setup. + + * "git stash push" takes a pathspec so that the local changes can be + stashed away only partially. + + * Documentation for "git ls-files" did not refer to core.quotePath. + + * The experimental "split index" feature has gained a few + configuration variables to make it easier to use. + + * From a working tree of a repository, a new option of "rev-parse" + lets you ask if the repository is used as a submodule of another + project, and where the root level of the working tree of that + project (i.e. your superproject) is. + + * The pathspec mechanism learned to further limit the paths that + match the pattern to those that have specified attributes attached + via the gitattributes mechanism. + + * Our source code has used the SHA1_HEADER cpp macro after "#include" + in the C code to switch among the SHA-1 implementations. Instead, + list the exact header file names and switch among implementations + using "#ifdef BLK_SHA1/#include "block-sha1/sha1.h"/.../#endif"; + this helps some IDE tools. + + * The start-up sequence of "git" needs to figure out some configured + settings before it finds and set itself up in the location of the + repository and was quite messy due to its "chicken-and-egg" nature. + The code has been restructured. + + * The command line prompt (in contrib/) learned a new 'tag' style + that can be specified with GIT_PS1_DESCRIBE_STYLE, to describe a + detached HEAD with "git describe --tags". + + * The configuration file learned a new "includeIf.<condition>.path" + that includes the contents of the given path only when the + condition holds. This allows you to say "include this work-related + bit only in the repositories under my ~/work/ directory". + + * Recent update to "rebase -i" started showing a message that is not + a warning with "warning:" prefix by mistake. This has been fixed. + + * Recently we started passing the "--push-options" through the + external remote helper interface; now the "smart HTTP" remote + helper understands what to do with the passed information. + + * "git describe --dirty" dies when it cannot be determined if the + state in the working tree matches that of HEAD (e.g. broken + repository or broken submodule). The command learned a new option + "git describe --broken" to give "$name-broken" (where $name is the + description of HEAD) in such a case. + + * "git checkout" is taught the "--recurse-submodules" option. + + * Recent enhancement to "git stash push" command to support pathspec + to allow only a subset of working tree changes to be stashed away + was found to be too chatty and exposed the internal implementation + detail (e.g. when it uses reset to match the index to HEAD before + doing other things, output from reset seeped out). These, and + other chattyness has been fixed. + + * "git merge <message> HEAD <commit>" syntax that has been deprecated + since October 2007 has been removed. + + * The refs completion for large number of refs has been sped up, + partly by giving up disambiguating ambiguous refs and partly by + eliminating most of the shell processing between 'git for-each-ref' + and 'ls-remote' and Bash's completion facility. + + * On many keyboards, typing "@{" involves holding down SHIFT key and + one can easily end up with "@{Up..." when typing "@{upstream}". As + the upstream/push keywords do not appear anywhere else in the syntax, + we can safely accept them case insensitively without introducing + ambiguity or confusion to solve this. + + * "git tag/branch/for-each-ref" family of commands long allowed to + filter the refs by "--contains X" (show only the refs that are + descendants of X), "--merged X" (show only the refs that are + ancestors of X), "--no-merged X" (show only the refs that are not + ancestors of X). One curious omission, "--no-contains X" (show + only the refs that are not descendants of X) has been added to + them. + + * The default behaviour of "git log" in an interactive session has + been changed to enable "--decorate". + + +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. + + * The "parse_config_key()" API function has been cleaned up. + + * A test that creates a confusing branch whose name is HEAD has been + corrected not to do so. + + * The code that parses header fields in the commit object has been + updated for (micro)performance and code hygiene. + + * An helper function to make it easier to append the result from + real_path() to a strbuf has been added. + + * Reduce authentication round-trip over HTTP when the server supports + just a single authentication method. This also improves the + behaviour when Git is misconfigured to enable http.emptyAuth + against a server that does not authenticate without a username + (i.e. not using Kerberos etc., which makes http.emptyAuth + pointless). + + * Windows port wants to use OpenSSL's implementation of SHA-1 + routines, so let them. + + * The t/perf performance test suite was not prepared to test not so + old versions of Git, but now it covers versions of Git that are not + so ancient. + + * Add 32-bit Linux variant to the set of platforms to be tested with + Travis CI. + + * "git branch --list" takes the "--abbrev" and "--no-abbrev" options + to control the output of the object name in its "-v"(erbose) + output, but a recent update started ignoring them; fix it before + the breakage reaches to any released version. + + * Picking two versions of Git and running tests to make sure the + older one and the newer one interoperate happily has now become + possible. + + * "uchar [40]" to "struct object_id" conversion continues. + + * "git tag --contains" used to (ab)use the object bits to keep track + of the state of object reachability without clearing them after + use; this has been cleaned up and made to use the newer commit-slab + facility. + + * The "debug" helper used in the test framework learned to run + a command under "gdb" interactively. + + * The "detect attempt to create collisions" variant of SHA-1 + implementation by Marc Stevens (CWI) and Dan Shumow (Microsoft) + has been integrated and made the default. + + * The test framework learned to detect unterminated here documents. + + * The name-hash used for detecting paths that are different only in + cases (which matter on case insensitive filesystems) has been + optimized to take advantage of multi-threading when it makes sense. + + * An earlier version of sha1dc/sha1.c that was merged to 'master' + compiled incorrectly on Windows, which has been fixed. + + * "what URL do we want to update this submodule?" and "are we + interested in this submodule?" are split into two distinct + concepts, and then the way used to express the latter got extended, + paving a way to make it easier to manage a project with many + submodules and make it possible to later extend use of multiple + worktrees for a project with submodules. + + * Some debugging output from "git describe" were marked for l10n, + but some weren't. Mark missing ones for l10n. + + * Define a new task in .travis.yml that triggers a test session on + Windows run elsewhere. + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.12 +----------------- + +Unless otherwise noted, all the fixes since v2.12 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. + + * 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). + + * "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. + + * "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. + + * 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. + + * "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. + + * 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. + + * The code to parse "git -c VAR=VAL cmd" and set configuration + variable for the duration of cmd had two small bugs, which have + been fixed. + + * user.email that consists of only cruft chars should consistently + error out, but didn't. + + * "git upload-pack", which is a counter-part of "git fetch", did not + report a request for a ref that was not advertised as invalid. + This is generally not a problem (because "git fetch" will stop + before making such a request), but is the right thing to do. + + * A leak in a codepath to read from a packed object in (rare) cases + has been plugged. + + * When a redirected http transport gets an error during the + redirected request, we ignored the error we got from the server, + and ended up giving a not-so-useful error message. + + * The patch subcommand of "git add -i" was meant to have paths + selection prompt just like other subcommand, unlike "git add -p" + directly jumps to hunk selection. Recently, this was broken and + "add -i" lost the paths selection dialog, but it now has been + fixed. + + * Git v2.12 was shipped with an embarrassing breakage where various + operations that verify paths given from the user stopped dying when + seeing an issue, and instead later triggering segfault. + + * There is no need for Python only to give a few messages to the + standard error stream, but we somehow did. + + * The code to parse "git log -L..." command line was buggy when there + are many ranges specified with -L; overrun of the allocated buffer + has been fixed. + + * The command-line parsing of "git log -L" copied internal data + structures using incorrect size on ILP32 systems. + + * "git diff --quiet" relies on the size field in diff_filespec to be + correctly populated, but diff_populate_filespec() helper function + made an incorrect short-cut when asked only to populate the size + field for paths that need to go through convert_to_git() (e.g. CRLF + conversion). + + * A few tests were run conditionally under (rare) conditions where + they cannot be run (like running cvs tests under 'root' account). + + * "git branch @" created refs/heads/@ as a branch, and in general the + code that handled @{-1} and @{upstream} was a bit too loose in + disambiguating. + + * "git fetch" that requests a commit by object name, when the other + side does not allow such an request, failed without much + explanation. + + * "git filter-branch --prune-empty" drops a single-parent commit that + becomes a no-op, but did not drop a root commit whose tree is empty. + + * Recent versions of Git treats http alternates (used in dumb http + transport) just like HTTP redirects and requires the client to + enable following it, due to security concerns. But we forgot to + give a warning when we decide not to honor the alternates. + + * "git push" had a handful of codepaths that could lead to a deadlock + when unexpected error happened, which has been fixed. + + * "Dumb http" transport used to misparse a nonsense http-alternates + response, which has been fixed. + + * "git add -p <pathspec>" unnecessarily expanded the pathspec to a + list of individual files that matches the pathspec by running "git + ls-files <pathspec>", before feeding it to "git diff-index" to see + which paths have changes, because historically the pathspec + language supported by "diff-index" was weaker. These days they are + equivalent and there is no reason to internally expand it.
