Torsten Bögershausen c24f3abace apply: file commited with CRLF should roundtrip diff and apply
When a file had been commited with CRLF but now .gitattributes say
"* text=auto" (or core.autocrlf is true), the following does not
roundtrip, `git apply` fails:

    printf "Added line\r\n" >>file &&
    git diff >patch &&
    git checkout -- . &&
    git apply patch

Before applying the patch, the file from working tree is converted
into the index format (clean filter, CRLF conversion, ...).  Here,
when commited with CRLF, the line endings should not be converted.

Note that `git apply --index` or `git apply --cache` doesn't call
convert_to_git() because the source material is already in index
format.

Analyze the patch if there is a) any context line with CRLF, or b)
if any line with CRLF is to be removed.  In this case the patch file
`patch` has mixed line endings, for a) it looks like this:

    diff --git a/one b/one
    index 533790e..c30dea8 100644
    --- a/one
    +++ b/one
    @@ -1 +1,2 @@
     a\r
    +b\r

And for b) it looks like this:

    diff --git a/one b/one
    index 533790e..485540d 100644
    --- a/one
    +++ b/one
    @@ -1 +1 @@
    -a\r
    +b\r

If `git apply` detects that the patch itself has CRLF, (look at the
line " a\r" or "-a\r" above), the new flag crlf_in_old is set in
"struct patch" and two things will happen:

    - read_old_data() will not convert CRLF into LF by calling
      convert_to_git(..., SAFE_CRLF_KEEP_CRLF);
    - The WS_CR_AT_EOL bit is set in the "white space rule",
      CRLF are no longer treated as white space.

While at there, make it clear that read_old_data() in apply.c knows
what it wants convert_to_git() to do with respect to CRLF.  In fact,
this codepath is about applying a patch to a file in the filesystem,
which may not exist in the index, or may exist but may not match
what is recorded in the index, or in the extreme case, we may not
even be in a Git repository.  If convert_to_git() peeked at the
index while doing its work, it *would* be a bug.

Pass NULL instead of &the_index to convert_to_git() to make sure we
catch future bugs to clarify this.

Update the test in t4124: split one test case into 3:

    - Detect the " a\r" line in the patch
    - Detect the "-a\r" line in the patch
    - Use LF in repo and CLRF in the worktree.

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

  • random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
  • stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
  • "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
  • "goddamn idiotic truckload of sh*t": when it breaks
