Currently, the --pretty=format prefix is looked up in a
tight loop in strbuf_expand(), if prefix is found it is then
used as argument for format_commit_item() that does another
search by a switch statement to select the proper operation.
Because the switch statement is already able to discard
unknown matches we don't need the prefix lookup before
to call format_commit_item().

curl versions 7.16.3 to 7.18.0 included had a regression in which https
requests following curl_global_cleanup/init sequence would fail with ASN1
parser errors with curl-gnutls. Such sequences happen in some cases such
as git fetch.
We work around this by removing the http_init and http_cleanup calls from
get_refs_via_curl, replacing them with a transport->data initialization
with the http_walker (which does http_init).
While the http_walker is not currently used in get_refs_via_curl, http

qsort in Windows 2000 (and various other C libraries) is a Quicksort
with the usual O(n^2) worst case. Unfortunately, sorting Git trees
seems to get very close to that worst case quite often:
$ /git/gitbad runstatus
# On branch master
qsort, nmemb = 30842
done, 237838087 comparisons.
This patch adds a simplified version of the merge sort that is glibc's
qsort(3). As a merge sort, this needs a temporary array equal in size
to the array that is to be sorted, but has a worst-case performance of
O(n log n).
The complexity that was removed is:
* Doing direct stores for word-size and -aligned data.
* Falling back to quicksort if the allocation required to perform the
merge sort would likely push the machine into swap.
Even with these simplifications, this seems to outperform the Windows
qsort(3) implementation, even in Windows XP (where it is "fixed" and
doesn't trigger O(n^2) complexity on trees).

Previously, we set the GIT_CONFIG environment variable in
our tests so that only that file was read. However, setting
it to a static value is not correct, since we are not
necessarily always in the same directory; instead, we want
the usual git config file lookup to happen.
To do this, we stop setting GIT_CONFIG, which means that we
must now suppress the reading of the system-wide and user
configs.
This exposes an incorrect test in t1500, which is also

CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout. A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git. For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes. Right
after committing you still have the original file in your work
tree and this file is not yet corrupted. You can explicitly tell
git that this file is binary and git will handle the file
appropriately.
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished. In both cases CRLFs are removed
in an irreversible way. For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
This patch adds a mechanism that can either warn the user about
an irreversible conversion or can even refuse to convert. The
mechanism is controlled by the variable core.safecrlf, with the
following values:
- false: disable safecrlf mechanism
- warn: warn about irreversible conversions
- true: refuse irreversible conversions
The default is to warn. Users are only affected by this default
if core.autocrlf is set. But the current default of git is to
leave core.autocrlf unset, so users will not see warnings unless
they deliberately chose to activate the autocrlf mechanism.
The safecrlf mechanism's details depend on the git command. The
general principles when safecrlf is active (not false) are:
- we warn/error out if files in the work tree can modified in an
irreversible way without giving the user a chance to backup the
original file.
- for read-only operations that do not modify files in the work tree
we do not not print annoying warnings.
There are exceptions. Even though...
- "git add" itself does not touch the files in the work tree, the
next checkout would, so the safety triggers;
- "git apply" to update a text file with a patch does touch the files
in the work tree, but the operation is about text files and CRLF
conversion is about fixing the line ending inconsistencies, so the
safety does not trigger;
- "git diff" itself does not touch the files in the work tree, it is
often run to inspect the changes you intend to next "git add". To
catch potential problems early, safety triggers.
The concept of a safety check was originally proposed in a similar
way by Linus Torvalds. Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

The prepare-commit-msg hook is run whenever a "fresh" commit message
is prepared, just before it is shown in the editor (if it is).
Its purpose is to modify the commit message in-place.
It takes one to three parameters. The first is the name of the file that
the commit log message. The second is the source of the commit message,
and can be: "message" (if a -m or -F option was given); "template" (if a
-t option was given or the configuration option commit.template is set);
"merge" (if the commit is a merge or a .git/MERGE_MSG file exists);
"squash" (if a .git/SQUASH_MSG file exists); or "commit", followed by
a commit SHA1 as the third parameter (if a -c, -C or --amend option
was given).
If its exit status is non-zero, git-commit will abort. The hook is
not suppressed by the --no-verify option, so it should not be used
as a replacement for the pre-commit hook.
The sample prepare-commit-msg comments out the `Conflicts:` part of
a merge's commit message; other examples are commented out, including
adding a Signed-off-by line at the bottom of the commit messsage,
that the user can then edit or discard altogether.

"git-help--browse" helper is to launch a browser of the user's choice
to view the HTML version of git documentation for a given command. It
used to take the name of a command, convert it to the path of the
documentation by prefixing the directory name and appending the
".html" suffix, and start the browser on the path.
This updates the division of labor between the caller in help.c and
git-help--browser helper. The helper is now responsible for launching
a browser of the user's choice on given URLs, and it is the caller's
responsibility to tell it the paths to documentation files.
This is in preparation to reuse the logic to choose user's preferred
browser in instaweb.
The helper had a provision for running it without any command name, in
which case it showed the toplevel "git(7)" documentation, but the
caller in help.c never makes such a call. The helper now exits with a
usage message when no path is given.

When we process "foo/" entries in gitignore files on a system
that does not have d_type member in "struct dirent", the earlier
implementation ran lstat(2) separately when matching with
entries that came from the command line, in-tree .gitignore
files, and $GIT_DIR/info/excludes file.
This optimizes it by delaying the lstat(2) call until it becomes
absolutely necessary.
The initial idea for this change was by Jeff King, but I
optimized it further to pass pointers to around.

A pattern "foo/" in the exclude list did not match directory
"foo", but a pattern "foo" did. This attempts to extend the
exclude mechanism so that it would while not matching a regular
file or a symbolic link "foo". In order to differentiate a
directory and non directory, this passes down the type of path
being checked to excluded() function.
A downside is that the recursive directory walk may need to run
lstat(2) more often on systems whose "struct dirent" do not give
the type of the entry; earlier it did not have to do so for an
excluded path, but we now need to figure out if a path is a
directory before deciding to exclude it. This is especially bad
because an idea similar to the earlier CE_UPTODATE optimization
to reduce number of lstat(2) calls would by definition not apply
to the codepaths involved, as (1) directories will not be
registered in the index, and (2) excluded paths will not be in
the index anyway.

An incorrect command "git mv subdir /outer/space" threw the
subdirectory to outside of the repository and then noticed that
/outer/space/subdir/ would be outside of the repository. The
error checking is backwards.
This fixes the issue by being careful about use of the return

We would need to notice and fail if command line had a nonsense pathspec.
Earlier get_pathspec() returned all the inputs including bad ones, but

The prefix_path() function called from get_pathspec() is
responsible for translating list of user-supplied pathspecs to
list of pathspecs that is relative to the root of the work
tree. When working inside a subdirectory, the user-supplied
pathspecs are taken to be relative to the current subdirectory.
Among special path components in pathspecs, we used to accept
and interpret only "." ("the directory", meaning a no-op) and
".." ("up one level") at the beginning. Everything else was
passed through as-is.
For example, if you are in Documentation/ directory of the
project, you can name Documentation/howto/maintain-git.txt as:
howto/maintain-git.txt
../Documentation/howto/maitain-git.txt
../././Documentation/howto/maitain-git.txt
but not as:
howto/./maintain-git.txt
$(pwd)/howto/maintain-git.txt
This patch updates prefix_path() in several ways:
- If the pathspec is not absolute, prefix (i.e. the current
subdirectory relative to the root of the work tree, with
terminating slash, if not empty) and the pathspec is
concatenated first and used in the next step. Otherwise,
that absolute pathspec is used in the next step.
- Then special path components "." (no-op) and ".." (up one
level) are interpreted to simplify the path. It is an error
to have too many ".." to cause the intermediate result to
step outside of the input to this step.
- If the original pathspec was not absolute, the result from
the previous step is the resulting "sanitized" pathspec.
Otherwise, the result from the previous step is still
absolute, and it is an error if it does not begin with the
directory that corresponds to the root of the work tree. The
directory is stripped away from the result and is returned.
- In any case, the resulting pathspec in the array
get_pathspec() returns omit the ones that caused errors.
With this patch, the last two examples also behave as expected.
