Updates since v2.14
-------------------
* The "rerere-train" script (in contrib/) learned the "--overwrite"
option to allow overwriting existing recorded resolutions.
- (merge ad53bf79aa rg/rerere-train-overwrite later to maint).
* "git contacts" (in contrib/) now lists the address on the
"Reported-by:" trailer to its output, in addition to those on
S-o-b: and other trailers, to make it easier to notify (and thank)
the original bug reporter.
- (merge 09ac673788 eb/contacts-reported-by later to maint).
* "git rebase", especially when it is run by mistake and ends up
trying to replay many changes, spent long time in silence. The
long time preparing these many changes to replay (which would give
the user a chance to abort with ^C).
+ * "git merge" learned a "--signoff" option to add the Signed-off-by:
+ trailer with the committer's name.
+
+ * "git diff" learned to optionally paint new lines that are the same
+ as deleted lines elsewhere differently from genuinely new lines.
+
+ * "git interpret-trailers" learned to take the trailer specifications
+ from the command line that overrides the configured values.
+
+ * "git interpret-trailers" has been taught a "--parse" and a few
+ other options to make it easier for scripts to grab existing
+ trailer lines from a commit log message.
+
+ * "gitweb" shows a link to visit the 'raw' contents of blbos in the
+ history overview page.
+
+ * "[gc] rerereResolved = 5.days" used to be invalid, as the variable
+ is defined to take an integer counting the number of days. It now
+ is allowed.
+
+ * The code to acquire a lock on a reference (e.g. while accepting a
+ push from a client) used to immediately fail when the reference is
+ already locked---now it waits for a very short while and retries,
+ which can make it succeed if the lock holder was holding it during
+ a read-only operation.
+
+ * "branch --set-upstream" that has been deprecated in Git 1.8 has
+ finally been retired.
+
+ * The codepath to call external process filter for smudge/clean
+ operation learned to show the progress meter.
+
Performance, Internal Implementation, Development Support etc.
* Because recent Git for Windows do come with a real msgfmt, the
build procedure for git-gui has been updated to use it instead of a
hand-rolled substitute.
- (merge 90dbf226ba js/git-gui-msgfmt-on-windows later to maint).
* "git grep --recurse-submodules" has been reworked to give a more
consistent output across submodule boundary (and do its thing
has been optimized out when we know we do not run the pre-commit hook.
(merge 680ee550d7 kw/commit-keep-index-when-pre-commit-is-not-run later to maint).
+ * Updates to the HTTP layer we made recently unconditionally used
+ features of libCurl without checking the existence of them, causing
+ compilation errors, which has been fixed. Also migrate the code to
+ check feature macros, not version numbers, to cope better with
+ libCurl that vendor ships with backported features.
+
+ * The API to start showing progress meter after a short delay has
+ been simplified.
+ (merge 8aade107dd jc/simplify-progress later to maint).
+
+ * Code clean-up to avoid mixing values read from the .gitmodules file
+ and values read from the .git/config file.
+
+ * We used to spend more than necessary cycles allocating and freeing
+ piece of memory while writing each index entry out. This has been
+ optimized.

DESCRIPTION

+Help parsing or adding 'trailers' lines, that look similar to RFC 822 e-mail
headers, at the end of the otherwise free-form part of a commit
message.
This command reads some patches or commit messages from either the
-<file> arguments or the standard input if no <file> is specified. Then
-this command applies the arguments passed using the `--trailer`
-option, if any, to the commit message part of each input file. The
-result is emitted on the standard output.
+<file> arguments or the standard input if no <file> is specified. If
+`--parse` is specified, the output consists of the parsed trailers.
+
+Otherwise, this command applies the arguments passed using the
+`--trailer` option, if any, to the commit message part of each input
+file. The result is emitted on the standard output.
Some configuration variables control the way the `--trailer` arguments
are applied to each commit message and the way any existing trailer in
trailer to the input messages. See the description of this
command.
+--where <placement>::
+--no-where::
+ Specify where all new trailers will be added. A setting
+ provided with '--where' overrides all configuration variables
+ and applies to all '--trailer' options until the next occurrence of
+ '--where' or '--no-where'.
+
+--if-exists <action>::
+--no-if-exists::
+ Specify what action will be performed when there is already at
+ least one trailer with the same <token> in the message. A setting
+ provided with '--if-exists' overrides all configuration variables
+ and applies to all '--trailer' options until the next occurrence of
+ '--if-exists' or '--no-if-exists'.
+
+--if-missing <action>::
+--no-if-missing::
+ Specify what action will be performed when there is no other
+ trailer with the same <token> in the message. A setting
+ provided with '--if-missing' overrides all configuration variables
+ and applies to all '--trailer' options until the next occurrence of
+ '--if-missing' or '--no-if-missing'.
+
+--only-trailers::
+ Output only the trailers, not any other parts of the input.
+
+--only-input::
+ Output only trailers that exist in the input; do not add any
+ from the command-line or by following configured `trailer.*`
+ rules.
+
+--unfold::
+ Remove any whitespace-continuation in trailers, so that each
+ trailer appears on a line by itself with its full content.

+ A convenience alias for `--only-trailers --only-input
+ --unfold`.

- * * Allocates a `struct tempfile` either as a static variable or on
- * the heap, initialized to zeros. Once you use the structure to
- * call `create_tempfile()`, it belongs to the tempfile subsystem
- * and its storage must remain valid throughout the life of the
- * program (i.e. you cannot use an on-stack variable to hold this
- * structure).
- *
* * Attempts to create a temporary file by calling
- * `create_tempfile()`.
+ * `create_tempfile()`. The resources used for the temporary file are
+ * managed by the tempfile API.
*
* * Writes new content to the file by either:
*
- * * writing to the file descriptor returned by `create_tempfile()`
- * (also available via `tempfile->fd`).
+ * * writing to the `tempfile->fd` file descriptor
*
* * calling `fdopen_tempfile()` to get a `FILE` pointer for the
* open file and writing to the file using stdio.
*
- * Note that the file descriptor returned by create_tempfile()
+ * Note that the file descriptor created by create_tempfile()
* is marked O_CLOEXEC, so the new contents must be written by
* the current process, not any spawned one.
*
* control of the file.
*
* * Close the file descriptor without removing or renaming the
- * temporary file by calling `close_tempfile()`, and later call
+ * temporary file by calling `close_tempfile_gently()`, and later call
* `delete_tempfile()` or `rename_tempfile()`.
*
- * Even after the temporary file is renamed or deleted, the `tempfile`
- * object must not be freed or altered by the caller. However, it may
- * be reused; just pass it to another call of `create_tempfile()`.
+ * After the temporary file is renamed or deleted, the `tempfile`
+ * object is no longer valid and should not be reused.
*
* If the program exits before `rename_tempfile()` or
* `delete_tempfile()` is called, an `atexit(3)` handler will close
* and remove the temporary file.
*
* If you need to close the file descriptor yourself, do so by calling
- * `close_tempfile()`. You should never call `close(2)` or `fclose(3)`
+ * `close_tempfile_gently()`. You should never call `close(2)` or `fclose(3)`
* yourself, otherwise the `struct tempfile` structure would still
* think that the file descriptor needs to be closed, and a later
* cleanup would result in duplicate calls to `close(2)`. Worse yet,
* Error handling
* --------------
*
- * `create_tempfile()` returns a file descriptor on success or -1 on
- * failure. On errors, `errno` describes the reason for failure.
+ * `create_tempfile()` returns an allocated tempfile on success or NULL
+ * on failure. On errors, `errno` describes the reason for failure.
*
- * `delete_tempfile()`, `rename_tempfile()`, and `close_tempfile()`
- * return 0 on success. On failure they set `errno` appropriately, do
- * their best to delete the temporary file, and return -1.
+ * `delete_tempfile()`, `rename_tempfile()`, and `close_tempfile_gently()`
+ * return 0 on success. On failure they set `errno` appropriately and return
+ * -1. `delete` and `rename` (but not `close`) do their best to delete the
