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.
+ (merge 9d3343961b jh/send-email-one-cc later to maint).
+
+ * 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.
+ (merge d1b3b81aab sb/submodule-init-url-selection later to maint).
+
+ * "git stash save" takes a pathspec so that the local changes can be
+ stashed away only partially.
+ (merge 9e140909f6 tg/stash-push later to maint).
+
+ * 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.
+
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.
+ (merge ad8c7cdadd jk/parse-config-key-cleanup later to maint).
+
+ * A test that creates a confusing branch whose name is HEAD has been
+ corrected not to do so.
+ (merge f0252ca23c jk/t6300-cleanup later to maint).
+
+ * The code that parses header fields in the commit object has been
+ updated for (micro)performance and code hygiene.
+ (merge b072504ce1 rs/commit-parsing-optim later to maint).
+
+ * An helper function to make it easier to append the result from
+ real_path() to a strbuf has been added.
+ (merge 33ad9ddd0b rs/strbuf-add-real-path later to maint).
+
+ * 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.
+ (merge 28e1fb5466 jt/perf-updates later to maint).
+
+ * 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.
+ (merge bd4d9d993c jk/interop-test later to maint).
+
+ * "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.
+
Also contains various documentation updates and code clean-ups.
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.
+ (merge 1274a155af jc/config-case-cmdline-take-2 later to maint).
+
+ * user.email that consists of only cruft chars should consistently
+ error out, but didn't.
+ (merge 94425552f3 jk/ident-empty later to maint).
+
+ * "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.
+ (merge bdb31eada7 jt/upload-pack-error-report later to maint).
+
+ * A leak in a codepath to read from a packed object in (rare) cases
+ has been plugged.
+ (merge 886ddf4777 rs/sha1-file-plug-fallback-base-leak later to maint).
+
+ * 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.
+ (merge b8686c661d ss/remote-bzr-hg-placeholder-wo-python later to maint).
+
+ * 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).
+ (merge 12426e114b jc/diff-populate-filespec-size-only-fix later to maint).
+
+ * A few tests were run conditionally under (rare) conditions where
+ they cannot be run (like running cvs tests under 'root' account).
+ (merge c6507484a2 ab/cond-skip-tests later to maint).
+
+ * "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.
+ (merge fd4692ff70 jk/interpret-branch-name later to maint).
+
+ * "git fetch" that requests a commit by object name, when the other
+ side does not allow such an request, failed without much
+ explanation.
+ (merge d56583ded6 mm/fetch-show-error-message-on-unadvertised-object later to maint).
+
+ * "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.
+ (merge 32da7467eb dp/filter-branch-prune-empty later to maint).
+
+ * 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.
+ (merge 5cae73d5d2 ew/http-alternates-as-redirects-warning later to maint).
+
+ * "git push" had a handful of codepaths that could lead to a deadlock
+ when unexpected error happened, which has been fixed.
+ (merge d1a13d3fcb jk/push-deadlock-regression-fix later to maint).
+
+ * "Dumb http" transport used to misparse a nonsense http-alternates
+ response, which has been fixed.
+ (merge d61434ae81 jk/http-walker-buffer-underflow-fix later to maint).
+
+ * "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.
+ (merge b9e2bc560a mg/status-porcelain-no-i18n later to maint).
+
* Other minor doc, test and build updates and code cleanups.
