+Git v2.12.1 Release Notes
+=========================
+
+Fixes since v2.12
+-----------------
+
+ * 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.
+
+ * Add 32-bit Linux variant to the set of platforms to be tested with
+ Travis CI.
+
+ * 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.
+
+ * 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.
+
+Also contains various documentation updates and code clean-ups.

+Git 2.13 Release Notes
+======================
+
+Backward compatibility notes.
+
+ * Use of an empty string as a pathspec element that is used for
+ 'everything matches' is still warned and Git asks users to use a
+ more explicit '.' for that instead. 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.
+
+ * "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.
+
+
+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.
+ (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).
+ (merge 40a18fc77c jk/http-auth later to maint).
+
+ * Windows port wants to use OpenSSL's implementation of SHA-1
+ routines, so let them.
+ (merge 2cfc70f0de jh/mingw-openssl-sha1 later to maint).
+
+ * 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.
+ (merge 88dedd5e72 js/travis-32bit-linux later to maint).
+
+ * "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.
+
+
+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).
+
+ * 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.
+ (merge 8e27391a5f jt/http-base-url-update-upon-redirect later to maint).
+
+ * 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.
+ (merge c852bd54bd jk/add-i-patch-do-prompt later to maint).
+
+ * 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.
+ (merge ce83eadd9a js/realpath-pathdup-fix later to maint).
+
+ * 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.
+ (merge aaae0bf787 ax/line-log-range-merge-fix later to maint).
+
+ * The command-line parsing of "git log -L" copied internal data
+ structures using incorrect size on ILP32 systems.
+ (merge 07f546cda5 vn/line-log-memcpy-size-fix later to maint).
+
+ * "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).
+
+ * Other minor doc, test and build updates and code cleanups.
+ (merge 2cfa83574c mm/two-more-xstrfmt later to maint).

+ If true, the split-index feature of the index will be used.

core.untrackedCache::
Determines what to do about the untracked cache feature of the
index. It will be kept, if this variable is unset or set to
all fields, including the sub-second part of mtime and ctime.
core.quotePath::
- The commands that output paths (e.g. 'ls-files',
- 'diff'), when not given the `-z` option, will quote
- "unusual" characters in the pathname by enclosing the
- pathname in a double-quote pair and with backslashes the
- same way strings in C source code are quoted. If this
- variable is set to false, the bytes higher than 0x80 are
- not quoted but output as verbatim. Note that double
- quote, backslash and control characters are always
- quoted without `-z` regardless of the setting of this
- variable.
+ Commands that output paths (e.g. 'ls-files', 'diff'), will
+ quote "unusual" characters in the pathname by enclosing the
+ pathname in double-quotes and escaping those characters with
+ backslashes in the same way C escapes control characters (e.g.
+ `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
+ values larger than 0x80 (e.g. octal `\302\265` for "micro" in
+ UTF-8). If this variable is set to false, bytes higher than
+ 0x80 are not considered "unusual" any more. Double-quotes,
+ backslash and control characters are always escaped regardless
+ of the setting of this variable. A simple space character is
+ not considered "unusual". Many commands can output pathnames
+ completely verbatim using the `-z` option. The default value
+ is true.
core.eol::
Sets the line ending type to use in the working directory for
Make `git gc --auto` return immediately and run in background
if the system supports it. Default is true.
+gc.logExpiry::
+ If the file gc.log exists, then `git gc --auto` won't run

This field must match exactly between the config key and the URL.
matched against are those given directly to Git commands. This means any URLs
visited as a result of a redirection do not participate in matching.
+ssh.variant::
+ Depending on the value of the environment variables `GIT_SSH` or
+ `GIT_SSH_COMMAND`, or the config setting `core.sshCommand`, Git
+ auto-detects whether to adjust its command-line parameters for use
+ with plink or tortoiseplink, as opposed to the default (OpenSSH).
++
+The config variable `ssh.variant` can be set to override this auto-detection;
+valid values are `ssh`, `plink`, `putty` or `tortoiseplink`. Any other value
+will be treated as normal ssh. This setting can be overridden via the
+environment variable `GIT_SSH_VARIANT`.
+

Character encoding the commit messages are stored in; Git itself
does not care per se, but this information is necessary e.g. when
The default set of branches for linkgit:git-show-branch[1].
See linkgit:git-show-branch[1].
+splitIndex.maxPercentChange::
+ When the split index feature is used, this specifies the
+ percent of entries the split index can contain compared to the
+ total number of entries in both the split index and the shared
+ index before a new shared index is written.
+ The value should be between 0 and 100. If the value is 0 then
+ a new shared index is always written, if it is 100 a new
+ shared index is never written.
+ By default the value is 20, so a new shared index is written
+ if the number of entries in the split index would be greater
+ than 20 percent of the total number of entries.
+ See linkgit:git-update-index[1].
+
+splitIndex.sharedIndexExpire::
+ When the split index feature is used, shared index files that
+ were not modified since the time this variable specifies will
+ be removed when a new shared index file is created. The value
+ "now" expires all entries immediately, and "never" suppresses
+ expiration altogether.
+ The default value is "2.weeks.ago".
+ Note that a shared index file is considered modified (for the
+ purpose of expiration) each time a new split-index file is
+ either created based on it or read from it.
+ See linkgit:git-update-index[1].
+
status.relativePaths::
By default, linkgit:git-status[1] shows paths relative to the
current directory. Setting this variable to `false` shows paths

-or ../), the location relative to the superproject's origin
+or ../), the location relative to the superproject's default remote
repository (Please note that to specify a repository 'foo.git'
which is located right next to a superproject 'bar.git', you'll
have to use '../foo.git' instead of './foo.git' - as one might expect
when following the rules for relative URLs - because the evaluation
of relative URLs in Git is identical to that of relative directories).

Querying Specific Attributes
----------------------------
-* Prepare an array of `struct git_attr_check` to define the list of
- attributes you would want to check. To populate this array, you would
- need to define necessary attributes by calling `git_attr()` function.
+* Prepare `struct attr_check` using attr_check_initl()
+ function, enumerating the names of attributes whose values you are
+ interested in, terminated with a NULL pointer. Alternatively, an
+ empty `struct attr_check` can be prepared by calling
+ `attr_check_alloc()` function and then attributes you want to
+ ask about can be added to it with `attr_check_append()`
+ function.
* Call `git_check_attr()` to check the attributes for the path.
-* Inspect `git_attr_check` structure to see how each of the attribute in
- the array is defined for the path.
+* Inspect `attr_check` structure to see how each of the

Querying All Attributes
-----------------------
To get the values of all attributes associated with a file:
-* Call `git_all_attrs()`, which returns an array of `git_attr_check`
- structures.
+* Prepare an empty `attr_check` structure by calling
+ `attr_check_alloc()`.
+
+* Call `git_all_attrs()`, which populates the `attr_check`
+ with the attributes attached to the path.
-* Iterate over the `git_attr_check` array to examine the attribute
- names and values. The name of the attribute described by a
- `git_attr_check` object can be retrieved via
- `git_attr_name(check[i].attr)`. (Please note that no items will be
- returned for unset attributes, so `ATTR_UNSET()` will return false
- for all returned `git_array_check` objects.)
+* Iterate over the `attr_check.items[]` array to examine
+ the attribute names and values. The name of the attribute
+ described by a `attr_check.items[]` object can be retrieved via
+ `git_attr_name(check->items[i].attr)`. (Please note that no items
+ will be returned for unset attributes, so `ATTR_UNSET()` will return
+ false for all returned `attr_check.items[]` objects.)
-* Free the `git_array_check` array.

+Git version interoperability tests
+==================================
+
+This directory has interoperability tests for git. Each script is
+similar to the normal test scripts found in t/, but with the added twist
+that two special versions of git, "git.a" and "git.b", are available in
+the PATH. Individual tests can then check the interaction between the
+two versions.
+
+When you add a feature that handles backwards compatibility between git
+versions, it's encouraged to add a test here to make sure it behaves as
+you expect.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make". This runs all
+the tests against their default versions.
+
+You can run a single test like:
+
+ $ ./i0000-basic.sh
+ ok 1 - bare git is forbidden
+ ok 2 - git.a version (v1.6.6.3)
+ ok 3 - git.b version (v2.11.1)
+ # passed all 3 test(s)
+ 1..3
+
+Each test contains default versions to run against. You may override
+these by setting `GIT_TEST_VERSION_A` and `GIT_TEST_VERSION_B` in the
+environment. Note that not all combinations will give sensible outcomes
+for all tests (e.g., a test checking for a specific old/new interaction
+may want something "old" enough" and something "new" enough; see
+individual tests for details).
+
+Version names should be resolvable as revisions in the current
+repository. They will be exported and built as needed using the
+config.mak files found at the root of your working tree.
+
+The exception is the special version "." which uses the currently-built
+contents of your working tree.
+
+You can set the following variables (in the environment or in your config.mak):
+
+ GIT_INTEROP_MAKE_OPTS
+ Options to pass to `make` when building a git version (e.g.,
+ `-j8`).
+
+You can also pass any command-line options taken by ordinary git tests (e.g.,
+"-v").
+
+
+Naming Tests
+------------
+
+The interop test files are named like:
+
+ iNNNN-short-description.sh
+
+where N is a decimal digit. The same conventions for choosing NNNN as
+for normal tests apply.
+
+
+Writing Tests
+-------------
+
+An interop test script starts like a normal script, declaring a few
+variables and then including interop-lib.sh (which includes test-lib.sh).
+Besides test_description, you should also set the $VERSION_A and $VERSION_B
+variables to give the default versions to test against. See t0000-basic.sh for
+an example.
+
+You can then use test_expect_success as usual, with a few differences:
+
+ 1. The special commands "git.a" and "git.b" correspond to the
+ two versions.
+
+ 2. You cannot call a bare "git". This is to prevent accidents where
+ you meant "git.a" or "git.b".
+
+ 3. The trash directory is _not_ a git repository by default. You
+ should create one with the appropriate version of git.
+
+At the end of the script, call test_done as usual.

+
+# This mirrors a repeated push setup:
+#
+# 1. A client repeatedly modifies some files, makes a
+# commit, and pushes the result. It does this N times
+# before we get around to repacking.
+#
+# 2. Each push generates a thin pack with the new version of
+# various objects. Let's consider some file in the root tree
+# which is updated in each commit.
+#
+# When generating push number X, we feed commit X-1 (and
+# thus blob X-1) as a preferred base. The resulting pack has
+# blob X as a thin delta against blob X-1.
+#
+# On the receiving end, "index-pack --fix-thin" will
+# complete the pack with a base copy of blob X-1.
+#
+# 3. In older versions of git, if we used the delta from
+# pack X, then we'd always find blob X-1 as a base in the
+# same pack (and generate a fresh delta).
+#
+# But with the pack mru, we jump from delta to delta
+# following the traversal order:
+#
+# a. We grab blob X from pack X as a delta, putting it at
+# the tip of our mru list.
+#
+# b. Eventually we move onto commit X-1. We need other
+# objects which are only in pack X-1 (in the test code
+# below, it's the containing tree). That puts pack X-1
+# at the tip of our mru list.
+#
+# c. Eventually we look for blob X-1, and we find the
+# version in pack X-1 (because it's the mru tip).
+#
+# Now we have blob X as a delta against X-1, which is a delta
+# against X-2, and so forth.
+#
+# In the real world, these small pushes would get exploded by
+# unpack-objects rather than "index-pack --fix-thin", but the
+# same principle applies to larger pushes (they only need one
+# repeatedly-modified file to generate the delta chain).
