This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

[verse]

DESCRIPTION
|
|
-----------
|
|
Splits mail messages in a mailbox into commit log message,
|
|
authorship information and patches, and applies them to the
|
|
current branch.
|
|
|
|
OPTIONS
|
|
-------
|
|
<mbox>|<Maildir>...::
|
|
The list of mailbox files to read patches from. If you do not
|
|
supply this argument, reads from the standard input. If you supply
|
|
directories, they'll be treated as Maildirs.
|
|
|
|
-s, --signoff::
|
|
Add `Signed-off-by:` line to the commit message, using
|
|
the committer identity of yourself.
|
|
|
|
-d=<dir>, --dotest=<dir>::
|
|
Instead of `.dotest` directory, use <dir> as a working
|
|
area to store extracted patches.
|
|
|
|
-k, --keep::
|
|
Pass `-k` flag to `git-mailinfo` (see gitlink:git-mailinfo[1]).
|
|
|
|
-u, --utf8::
|
|
Pass `-u` flag to `git-mailinfo` (see gitlink:git-mailinfo[1]).
|
|
The proposed commit log message taken from the e-mail
|
|
is re-coded into UTF-8 encoding (configuration variable
|
|
`i18n.commitencoding` can be used to specify project's
|
|
preferred encoding if it is not UTF-8).
|
|
+
|
|
This was optional in prior versions of git, but now it is the
|
|
default. You could use `--no-utf8` to override this.
|
|
|
|
--no-utf8::
|
|
Pass `-n` flag to `git-mailinfo` (see
|
|
gitlink:git-mailinfo[1]).
|
|
|
|
-3, --3way::
|
|
When the patch does not apply cleanly, fall back on
|
|
3-way merge, if the patch records the identity of blobs
|
|
it is supposed to apply to, and we have those blobs
|
|
available locally.
|
|
|
|
-b, --binary::
|
|
Pass `--allow-binary-replacement` flag to `git-apply`
|
|
(see gitlink:git-apply[1]).
|
|
|
|
--whitespace=<option>::
|
|
This flag is passed to the `git-apply` (see gitlink:git-apply[1])
|
|
program that applies
|
|
the patch.
|
|
|
|
-C<n>, -p<n>::
|
|
These flags are passed to the `git-apply` (see gitlink:git-apply[1])
|
|
program that applies
|
|
the patch.
|
|
|
|
-i, --interactive::
|
|
Run interactively.
|
|
|
|
--skip::
|
|
Skip the current patch. This is only meaningful when
|
|
restarting an aborted patch.
|
|
|
|
-r, --resolved::
|
|
After a patch failure (e.g. attempting to apply
|
|
conflicting patch), the user has applied it by hand and
|
|
the index file stores the result of the application.
|
|
Make a commit using the authorship and commit log
|
|
extracted from the e-mail message and the current index
|
|
file, and continue.
|
|
|
|
--resolvemsg=<msg>::
|
|
When a patch failure occurs, <msg> will be printed
|
|
to the screen before exiting. This overrides the
|
|
standard message informing you to use `--resolved`
|
|
or `--skip` to handle the failure. This is solely
|
|
for internal use between `git-rebase` and `git-am`.
|
|
|
|
DISCUSSION
|
|
----------
|
|
|
|
The commit author name is taken from the "From: " line of the
|
|
message, and commit author time is taken from the "Date: " line
|
|
of the message. The "Subject: " line is used as the title of
|
|
the commit, after stripping common prefix "[PATCH <anything>]".
|
|
It is supposed to describe what the commit is about concisely as
|
|
a one line text.
|
|
|
|
The body of the message (iow, after a blank line that terminates
|
|
RFC2822 headers) can begin with "Subject: " and "From: " lines
|
|
that are different from those of the mail header, to override
|
|
the values of these fields.
|
|
|
|
The commit message is formed by the title taken from the
|
|
"Subject: ", a blank line and the body of the message up to
|
|
where the patch begins. Excess whitespaces at the end of the
|
|
lines are automatically stripped.
|
|
|
|
The patch is expected to be inline, directly following the
|
|
message. Any line that is of form:
|
|
|
|
* three-dashes and end-of-line, or
|
|
* a line that begins with "diff -", or
|
|
* a line that begins with "Index: "
|
|
|
|
is taken as the beginning of a patch, and the commit log message
|
|
is terminated before the first occurrence of such a line.
|
|
|
|
When initially invoking it, you give it names of the mailboxes
|
|
to crunch. Upon seeing the first patch that does not apply, it
|
|
aborts in the middle,. You can recover from this in one of two ways:
|
|
|
|
. skip the current patch by re-running the command with '--skip'
|
|
option.
|
|
|
|
. hand resolve the conflict in the working directory, and update
|
|
the index file to bring it in a state that the patch should
|
|
have produced. Then run the command with '--resolved' option.
|
|
|
|
The command refuses to process new mailboxes while `.dotest`
|
|
directory exists, so if you decide to start over from scratch,
|
|
run `rm -f .dotest` before running the command with mailbox
|
|
names.
