+Git v2.15.2 Release Notes
+=========================
+
+Fixes since v2.15.1
+-------------------
+
+ * Recent update to the refs infrastructure implementation started
+ rewriting packed-refs file more often than before; this has been
+ optimized again for most trivial cases.
+
+ * The SubmittingPatches document has been converted to produce an
+ HTML version via AsciiDoc/Asciidoctor.
+
+ * Contrary to the documentation, "git pull -4/-6 other-args" did not
+ ask the underlying "git fetch" to go over IPv4/IPv6, which has been
+ corrected.
+
+ * When "git rebase" prepared an mailbox of changes and fed it to "git
+ am" to replay them, it was confused when a stray "From " happened
+ to be in the log message of one of the replayed changes. This has
+ been corrected.
+
+ * Command line completion (in contrib/) has been taught about the
+ "--copy" option of "git branch".
+
+ * "git apply --inaccurate-eof" when used with "--ignore-space-change"
+ triggered an internal sanity check, which has been fixed.
+
+ * The sequencer machinery (used by "git cherry-pick A..B", and "git
+ rebase -i", among other things) would have lost a commit if stopped
+ due to an unlockable index file, which has been fixed.
+
+ * The three-way merge performed by "git cherry-pick" was confused
+ when a new submodule was added in the meantime, which has been
+ fixed (or "papered over").
+
+ * "git notes" sent its error message to its standard output stream,
+ which was corrected.
+
+ * A few scripts (both in production and tests) incorrectly redirected
+ their error output. These have been corrected.
+
+ * Clarify and enhance documentation for "merge-base --fork-point", as
+ it was clear what it computed but not why/what for.
+
+
+Also contains various documentation updates and code clean-ups.
* The SubmittingPatches document has been converted to produce an
HTML version via AsciiDoc/Asciidoctor.
- (merge 049e64aa50 bc/submitting-patches-in-asciidoc later to maint).
* We learned to talk to watchman to speed up "git status" and other
operations that need to see which paths have been modified.
+ * The "diff" family of commands learned to ignore differences in
+ carriage return at the end of line.
+
+ * Places that know about "sendemail.to", like documentation and shell
+ completion (in contrib/) have been taught about "sendemail.tocmd",
+ too.
+
+ * "git add --renormalize ." is a new and safer way to record the fact
+ that you are correcting the end-of-line convention and other
+ "convert_to_git()" glitches in the in-repository data.
+
+ * "git branch" and "git checkout -b" are now forbidden from creating
+ a branch whose name is "HEAD".
+
+ * "git branch --list" learned to show its output through the pager by
+ default when the output is going to a terminal, which is controlled
+ by the pager.branch configuration variable. This is similar to a
+ recent change to "git tag --list".
+
+ * "git grep -W", "git diff -W" and their friends learned a heuristic
+ to extend a pre-context beyond the line that matches the "function
+ pattern" (aka "diff.*.xfuncname") to include a comment block, if
+ exists, that immediately precedes it.
+
+ * "git config --expiry-date gc.reflogexpire" can read "2.weeks" from
+ the configuration and report it as a timestamp, just like "--int"
+ would read "1k" and report 1024, to help consumption by scripts.
+
+ * The shell completion (in contrib/) learned that "git pull" can take
+ the "--autostash" option.
+
+ * The tagnames "git log --decorate" uses to annotate the commits can
+ now be limited to subset of available refs with the two additional
+ options, --decorate-refs[-exclude]=<pattern>.
+
+ * "git grep" compiled with libpcre2 sometimes triggered a segfault,
+ which is being fixed.
+
+ * "git send-email" tries to see if the sendmail program is available
+ in /usr/lib and /usr/sbin; extend the list of locations to be
+ checked to also include directories on $PATH.
+
Performance, Internal Implementation, Development Support etc.
* Drop (perhaps overly cautious) sanity check before using the index
read from the filesystem at runtime.
+ * The build procedure has been taught to avoid some unnecessary
+ instability in the build products.
+
+ * A new mechanism to upgrade the wire protocol in place is proposed
+ and demonstrated that it works with the older versions of Git
+ without harming them.
+
+ * An infrastructure to define what hash function is used in Git is
+ introduced, and an effort to plumb that throughout various
+ codepaths has been started.
+
+ * The code to iterate over loose object files got optimized.
+
+ * An internal function that was left for backward compatibility has
+ been removed, as there is no remaining callers.

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).
+ By default, Git determines the command line arguments to use
+ based on the basename of the configured SSH command (configured
+ using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
+ the config setting `core.sshCommand`). If the basename is
+ unrecognized, Git will attempt to detect support of OpenSSH
+ options by first invoking the configured SSH command with the
+ `-G` (print configuration) option and will subsequently use
+ OpenSSH options (if that is successful) or no options besides
+ the host and remote command (if it fails).
++
+The config variable `ssh.variant` can be set to override this detection.
+Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
+`tortoiseplink`, `simple` (no options except the host and remote command).
+The default auto-detection can be explicitly requested using the value
+`auto`. Any other value is treated as `ssh`. This setting can also be
+overridden via the environment variable `GIT_SSH_VARIANT`.
++
+The current command-line parameters used for each variant are as
+follows:
+
-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`.
+--
+
+* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
+
+* `simple` - [username@]host command
+
+* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
+
+* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command

++
+Except for the `simple` variant, command-line parameters are likely to
+change as git gains new features.

DESCRIPTION
After the clone is created, initialize and clone submodules

provided, all submodules are initialized and cloned.
- Submodules are initialized and cloned using their default

+ of multiple entries. The resulting clone has `submodule.active` set to
the provided pathspec, or "." (meaning all submodules) if no
- pathspec is provided. This is equivalent to running
- `git submodule update --init --recursive` immediately after
- the clone is finished. This option is ignored if the cloned
- repository does not have a worktree/checkout (i.e. if any of
- `--no-checkout`/`-n`, `--bare`, or `--mirror` is given)
+ pathspec is provided.
++
+Submodules are initialized and cloned using their default settings. This is
+equivalent to running
+`git submodule update --init --recursive <pathspec>` immediately after
+the clone is finished. This option is ignored if the cloned repository does
+not have a worktree/checkout (i.e. if any of `--no-checkout`/`-n`, `--bare`,
+or `--mirror` is given)

from the command line to let your shell do the expansion).
+--expiry-date::
+ `git config` will ensure that the output is converted from

+ has no effect when setting the value.

--null::
For all options that output values and/or keys, always
are shown as if 'short' were given, otherwise no ref names are
shown. The default option is 'short'.
+--decorate-refs=<pattern>::
+--decorate-refs-exclude=<pattern>::
+ If no `--decorate-refs` is given, pretend as if all refs were
+ included. For each candidate, do not use it for decoration if it
+ matches any patterns given to `--decorate-refs-exclude` or if it
+ doesn't match any of the patterns given to `--decorate-refs`.
+
--source::
Print out the ref name given on the command line by which each

`origin/master` may have been rewound and rebuilt, leading to a
history of this shape:
- o---B1
+ o---B2
/
- ---o---o---B2--o---o---o---B (origin/master)
+ ---o---o---B1--o---o---o---B (origin/master)
\

+ B0
\
- Derived (topic)
+ D0---D1---D (topic)
-where `origin/master` used to point at commits B3, B2, B1 and now it
+where `origin/master` used to point at commits B0, B1, B2 and now it
points at B, and your `topic` branch was started on top of it back
-when `origin/master` was at B3. This mode uses the reflog of
-`origin/master` to find B3 as the fork point, so that the `topic`
-can be rebased on top of the updated `origin/master` by:
+when `origin/master` was at B0, and you built three commits, D0, D1,
+and D, on top of it. Imagine that you now want to rebase the work
+you did on the topic on top of the updated origin/master.
+
+In such a case, `git merge-base origin/master topic` would return the
+parent of B0 in the above picture, but B0^..D is *not* the range of
+commits you would want to replay on top of B (it includes B0, which
+is not what you wrote; it is a commit the other side discarded when
+it moved its tip from B0 to B1).
+
+`git merge-base --fork-point origin/master topic` is designed to
+help in such a case. It takes not only B but also B0, B1, and B2
+(i.e. old tips of the remote-tracking branches your repository's
+reflog knows about) into account to see on which commit your topic
+branch was built and finds B0, allowing you to replay only the
+commits on your topic, excluding the commits the other side later
+discarded.
+
+Hence
$ fork_point=$(git merge-base --fork-point origin/master topic)
+
+will find B0, and
+
$ git rebase --onto origin/master $fork_point topic
+will replay D0, D1 and D on top of B to create a new history of this
+shape:
+
+ o---B2
+ /
+ ---o---o---B1--o---o---o---B (origin/master)
+ \ \
+ B0 D0'--D1'--D' (topic - updated)
+ \
+ D0---D1---D (topic - old)
+
+A caveat is that older reflog entries in your repository may be
+expired by `git gc`. If B0 no longer appears in the reflog of the
+remote-tracking branch `origin/master`, the `--fork-point` mode
+obviously cannot find it and fails, avoiding to give a random and
+useless result (such as the parent of B0, like the same command
+without the `--fork-point` option gives).
+
+Also, the remote-tracking branch you use the `--fork-point` mode
+with must be the one your topic forked from its tip. If you forked
+from an older commit than the tip, this mode would not find the fork
+point (imagine in the above sample history B0 did not exist,
+origin/master started at B1, moved to B2 and then B, and you forked
+your topic at origin/master^ when origin/master was B1; the shape of
+the history would be the same as above, without B0, and the parent
+of B1 is what `git merge-base origin/master topic` correctly finds,
+but the `--fork-point` mode will not, because it is not one of the
+commits that used to be at the tip of origin/master).

DISCUSSION
----------
line option or the 'git submodule summary' command, which shows a similar
output but does not honor these settings.
+BACKGROUND REFRESH
+------------------
+
+By default, `git status` will automatically refresh the index, updating
+the cached stat information from the working tree and writing out the
+result. Writing out the updated index is an optimization that isn't
+strictly necessary (`status` computes the values for itself, but writing
+them out is just to save subsequent programs from repeating our
+computation). When `status` is run in the background, the lock held
+during the write may conflict with other simultaneous processes, causing
+them to fail. Scripts running `status` in the background should consider
+using `git --no-optional-locks status` (see linkgit:git[1] for details).

If either of these environment variables is set then 'git fetch'
and 'git push' will use the specified command instead of 'ssh'
when they need to connect to a remote system.
- The command will be given exactly two or four arguments: the
- 'username@host' (or just 'host') from the URL and the shell
- command to execute on that remote system, optionally preceded by
- `-p` (literally) and the 'port' from the URL when it specifies
- something other than the default SSH port.
+ The command-line parameters passed to the configured command are
+ determined by the ssh variant. See `ssh.variant` option in
+ linkgit:git-config[1] for details.
+
+
`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted
by the shell, which allows additional arguments to be included.

`GIT_OPTIONAL_LOCKS`::
If set to `0`, Git will complete any requested operation without
performing any optional sub-operations that require taking a lock.

The file:// transport runs the 'upload-pack' or 'receive-pack'
process locally and communicates with it over a pipe.
+Extra Parameters
+----------------
+
+The protocol provides a mechanism in which clients can send additional
+information in its first message to the server. These are called "Extra
+Parameters", and are supported by the Git, SSH, and HTTP protocols.
+
+Each Extra Parameter takes the form of `<key>=<value>` or `<key>`.
+
+Servers that receive any such Extra Parameters MUST ignore all
+unrecognized keys. Currently, the only Extra Parameter recognized is
+"version=1".

Git Transport
-------------

hostname parameter, terminated by a NUL byte.
- 0032git-upload-pack /project.git\0host=myserver.com\0
+ 0033git-upload-pack /project.git\0host=myserver.com\0
+
+The transport may send Extra Parameters by adding an additional NUL
+byte, and then adding one or more NUL-terminated strings:
+
+ 003egit-upload-pack /project.git\0host=myserver.com\0\0version=1\0
--
- git-proto-request = request-command SP pathname NUL [ host-parameter NUL ]
+ git-proto-request = request-command SP pathname NUL
+ [ host-parameter NUL ] [ NUL extra-parameters ]
request-command = "git-upload-pack" / "git-receive-pack" /
"git-upload-archive" ; case sensitive
pathname = *( %x01-ff ) ; exclude NUL
host-parameter = "host=" hostname [ ":" port ]
+ extra-parameters = 1*extra-parameter
+ extra-parameter = 1*( %x01-ff ) NUL
--

+Depending on the value of the `protocol.version` configuration variable,
+Git may attempt to send Extra Parameters as a colon-separated string in
+the GIT_PROTOCOL environment variable. This is done only if
+the `ssh.variant` configuration variable indicates that the ssh command
+supports passing environment variables as an argument.
+
A few things to remember here:
- The "command name" is spelled with dash (e.g. git-upload-pack), but
-------------------
When the client initially connects the server will immediately respond
-with a listing of each reference it has (all branches and tags) along
+with a version number (if "version=1" is sent as an Extra Parameter),
+and a listing of each reference it has (all branches and tags) along
with the object name that each reference currently points to.

+It is common for fetch to consider objects that we might not have, and it is an

+re-scanning the pack directory for lookup failures).
+
+The resulting performance drop can be hard to notice in a real repository, but
