has been deprecated for quite some time, and will be removed in a
future release.
+ * 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".
+
Updates since v2.12
-------------------
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.
+
Performance, Internal Implementation, Development Support etc.
* 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.
+
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
+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.
- (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
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).
+
+ * 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. This
+ helps both performance and avoids command line argument limit on
+ some platforms.
+ (merge 7288e12cce jk/add-i-use-pathspecs later to maint).
+
+ * "git status --porcelain" is supposed to give a stable output, but a
+ few strings were left as translatable by mistake.
+
+ * "git revert -m 0 $merge_commit" complained that reverting a merge
+ needs to say relative to which parent the reversion needs to
+ happen, as if "-m 0" weren't given. The correct diagnosis is that
+ "-m 0" does not refer to the first parent ("-m 1" does). This has
+ been fixed.
+
+ * Code to read submodule.<name>.ignore config did not state the
+ variable name correctly when giving an error message diagnosing
+ misconfiguration.
+
+ * Fix for NO_PTHREADS build.
+
+ * Fix for potential segv introduced in v2.11.0 and later (also
+ v2.10.2) to "git log --pickaxe-regex -S".
+
+ * A few unterminated here documents in tests were fixed, which in
+ turn revealed incorrect expectations the tests make. These tests
+ have been updated.
+
+ * Fix for NO_PTHREADS option.
+ (merge 2225e1ea20 bw/grep-recurse-submodules later to maint).
* Other minor doc, test and build updates and code cleanups.
