These tests just want a bit-for-bit identical copy; they do not need
even -H (there is no symbolic link involved) nor -p (there is no
funny permission or ownership issues involved).
Just use "cp -R" instead.

This test script uses "svn cp" to create a branch with an @-sign in
its name:
svn cp "pr ject/trunk" "pr ject/branches/not-a@{0}reflog"
That sets up for later tests that fetch the branch and check that git
svn mangles the refname appropriately.
Unfortunately, modern svn versions interpret path arguments with an
@-sign as an example of path@revision syntax (which pegs a path to a
particular revision) and truncate the path or error out with message
"svn: E205000: Syntax error parsing peg revision '{0}reflog'".
When using subversion 1.6.x, escaping the @ sign as %40 avoids trouble
(see 08fd28bb, 2010-07-08). Newer versions are stricter:
$ svn cp "$repo/pr ject/trunk" "$repo/pr ject/branches/not-a%40{reflog}"
svn: E205000: Syntax error parsing peg revision '%7B0%7Dreflog'
The recommended method for escaping a literal @ sign in a path passed
to subversion is to add an empty peg revision at the end of the path
("branches/not-a@{0}reflog@"). Do that.
Pre-1.6.12 versions of Subversion probably treat the trailing @ as
another literal @-sign (svn issue 3651). Luckily ever since
v1.8.0-rc0~155^2~7 (t9118: workaround inconsistency between SVN
versions, 2012-07-28) the test can survive that.
Tested with Debian Subversion 1.6.12dfsg-6 and 1.7.5-1 and r1395837
of Subversion trunk (1.8.x).

The fsck test assumed too much on what kind of error it will
detect. The only important thing is the inconsistency is detected
as an error.

When a tag T points at an object X that is of a type that is
different from what the tag records as, fsck should report it as an
error.
However, depending on the order X and T are checked individually,
the actual error message can be different. If X is checked first,
fsck remembers X's type and then when it checks T, it notices that T
records X as a wrong type (i.e. the complaint is about a broken tag
T). If T is checked first, on the other hand, fsck remembers that we
need to verify X is of the type tag records, and when it later
checks X, it notices that X is of a wrong type (i.e. the complaint
is about a broken object X).
The important thing is that fsck notices such an error and diagnoses
the issue on object X, but the test was expecting that we happen to
check objects in the order to make us detect issues with tag T, not
with object X. Remove this unwarranted assumption.

When using the {word,[...]} style of configuration for tags and branches,
it appears the intent is to only match whole path parts, since the words
in the {} pattern are meta-character quoted.
When the pattern word appears in the beginning or middle of the url,
it's matched completely, since the left side, pattern, and (non-empty)
right side are joined together with path separators.
However, when the pattern word appears at the end of the URL, the
right side is an empty pattern, and the resulting regex matches
more than just the specified pattern.
For example, if you specify something along the lines of
branches = branches/project/{release_1,release_2}
and your repository also contains "branches/project/release_1_2", you
will also get the release_1_2 branch. By restricting the match regex
with anchors, this is avoided.

This fixes a bug where git finds the incorrect merge parent. Consider a
repository with trunk, branch1 of trunk, and branch2 of branch1.
Without this change, git interprets a merge of branch2 into trunk as a
merge of branch1 into trunk.

Consider the case where you have trunk, branch1 of trunk, and branch2 of
branch1. trunk is merged back into branch2, and then branch2 is
reintegrated into trunk. The merge of branch2 into trunk will have
svn:mergeinfo property references to both branch1 and branch2. When
git-svn fetches the commit that merges branch2 (check_cherry_pick),
it is necessary to eliminate the merged contents of branch1 as well as
branch2, or else the merge will be incorrectly ignored as a cherry-pick.

Similar to --author/--committer which filters commits by author and
committer header fields. --grep-reflog adds a fake "reflog" header to
commit and a grep filter to search on that line.
All rules to --author/--committer apply except no timestamp stripping.

grep supports only author and committer headers, which have the same
special treatment that later headers may or may not have. Check for
field type and only strip_timestamp() when the field is either author
or committer.
GREP_HEADER_FIELD_MAX is put in the grep_header_field enum to be
calculated automatically, correctly, as long as it's at the end of the
enum.

Even during a conflicted merge, "git blame $path" always meant to
blame uncommitted changes to the "working tree" version; make it
more useful by showing cleanly merged parts as coming from the other
branch that is being merged.
This incidentally fixes an unrelated problem on a case insensitive
filesystem, where "git blame MAKEFILE" run in a history that has
"Makefile" but not "MAKEFILE" did not say "No such file MAKEFILE in
HEAD" but pretended as if "MAKEFILE" was a newly added file.

Allow users to override the default commands provided by the
mergetools/* scriptlets.
Users occasionally run into problems where they expect to be
able to override the built-in tool names. The documentation
does not explicitly mention that built-ins cannot be overridden,
so it's easy to assume that it should work.
Lift this restriction so that built-in tools are handled the
same way as user-configured tools. Add tests to guarantee this
behavior.
A nice benefit of this change is that it protects users from
having future versions of git trump their custom configuration
with a new built-in tool.

To dest
! [remote rejected] HEAD -> master (n/a (unpacker error))
That n/a is meant to be "the per-ref status is not

ugly. Let's turn the final line into just:
! [remote rejected] HEAD -> master (unpacker error)

After running "git clone --single", the resulting repository has the
usual default "+refs/heads/*:refs/remotes/origin/*" wildcard fetch
refspec installed, which means that a subsequent "git fetch" will
end up grabbing all the other branches.
Update the fetch refspec to cover only the singly cloned ref instead
to correct this.
That means:
If "--single" is used without "--branch" or "--mirror", the
fetch refspec covers the branch on which remote's HEAD points to.
If "--single" is used with "--branch", it'll cover only the branch
specified in the "--branch" option.
If "--single" is combined with "--mirror", then it'll cover all
refs of the cloned repository.
If "--single" is used with "--branch" that specifies a tag, then
it'll cover only the ref for this tag.

"git submodule" command DWIMs the command line and assumes a
unspecified action word for 'status' action. This is a UI mistake
that leads to a confusing behaviour. A mistyped command name is
instead treated as a request for 'status' of the submodule with that
name, e.g.
$ git submodule show
error: pathspec 'show' did not match any file(s) known to git.
Did you forget to 'git add'?
Stop DWIMming an unknown or mistyped subcommand name as pathspec
given to unspelled "status" subcommand. "git submodule" without any
argument is still interpreted as "git submodule status", but its
value is questionable.
Adjust t7400 to match, and stop advertising the default subcommand
being 'status' which does not help much in practice, other than
promoting laziness and confusion.

Usually there is no need for users to specify whether an
http remote is smart or dumb; the protocol is designed so
that a single initial request is made, and the client can
determine the server's capability from the response.
However, some misconfigured dumb-only servers may not like
the initial request by a smart client, as it contains a
query string. Until recently, commit 703e6e7 worked around
this by making a second request. However, that commit was
recently reverted due to its side effect of masking the
initial request's error code.
Since git has had that workaround for several years, we
don't know exactly how many such misconfigured servers are
out there. The reversion of 703e6e7 assumes they are rare
enough not to worry about. Still, that reversion leaves
somebody who does run into such a server with no escape
hatch at all. Let's give them an environment variable they
can tweak to perform the "dumb" request.
This is intentionally not a documented interface. It's
overly simple and is really there for debugging in case
somebody does complain about git not working with their
server. A real user-facing interface would entail a
per-remote or per-URL config variable.

Some HTTP servers try to use gzip compression on the /info/refs
request to save transfer bandwidth. Repositories with many tags
may find the /info/refs request can be gzipped to be 50% of the
original size due to the few but often repeated bytes used (hex
SHA-1 and commonly digits in tag names).
For most HTTP requests enable "Accept-Encoding: gzip" ensuring
the /info/refs payload can use this encoding format.
Only request gzip encoding from servers. Although deflate is
supported by libcurl, most servers have standardized on gzip
encoding for compression as that is what most browsers support.
Asking for deflate increases request sizes by a few bytes, but is
unlikely to ever be used by a server.
Disable the Accept-Encoding header on probe RPCs as response bodies
are supposed to be exactly 4 bytes long, "0000". The HTTP headers
requesting and indicating compression use more space than the data
transferred in the body.

When the todo sheet of interactive rebase instructs to run a non-existing
command, the operation stops with the following error:
Execution failed: no-such
You can fix the problem, and then run
git rebase --continue
fatal: 'rebase' appears to be a git command, but we were not
able to execute it. Maybe git-rebase is broken?
The reason is that the shell that attempted to run the command exits with
code 127. rebase--interactive just forwards this code to the caller (the
git wrapper). But our smart run-command infrastructure detects this
special exit code and turns it into ENOENT, which in turn is interpreted
by the git wrapper as if the external command that it just executed did
not exist. This is finally translated to the misleading last two lines in
error message cited above.
Fix it by translating the error code before it is forwarded.

The codepath for handling "--tee" ends up relaunching the test
script under a shell, and that one has to be a Bourne. But we
incorrectly used $SHELL, which could be a non-Bourne (e.g. zsh or
csh); we have the Makefile variable $SHELL_PATH for exactly that,
so use it instead.

uses a fixed MALLOC_PERTURB_ in order to avoid hurting repeatability
of the tests.

detecting heap corruption
Recent versions of Linux libc (later than 5.4.23) and glibc (2.x)
include a malloc() implementation which is tunable via environment
variables. When MALLOC_CHECK_ is set, a special (less efficient)
implementation is used which is designed to be tolerant against
simple errors, such as double calls of free() with the same argument,
or overruns of a single byte (off-by-one bugs). When MALLOC_CHECK_
is set to 3, a diagnostic message is printed on stderr
and the program is aborted.
Setting the MALLOC_PERTURB_ environment variable causes the malloc
functions in libc to return memory which has been wiped and clear
memory when it is returned.
Of course this does not affect calloc which always does clear the memory.
The reason for this exercise is, of course, to find code which uses
memory returned by malloc without initializing it and code which uses
code after it is freed. valgrind can do this but it's costly to run.
The MALLOC_PERTURB_ exchanges the ability to detect problems in 100%
of the cases with speed.
The byte value used to initialize values returned by malloc is the byte
value of the environment value. The value used to clear memory is the
bitwise inverse. Setting MALLOC_PERTURB_ to zero disables the feature.
This technique can find hard to detect bugs.
It is therefore suggested to always use this flag (at least temporarily)
when testing out code or a new distribution.
But the test suite can use also valgrind(memcheck) via 'make valgrind'
or 'make GIT_TEST_OPTS="--valgrind"'.
Memcheck wraps client calls to malloc(), and puts a "red zone" on
each end of each block in order to detect access overruns.
Memcheck already detects double free() (up to the limit of the buffer
which remembers pending free()). Thus memcheck subsumes all the
documented coverage of MALLOC_CHECK_.
If MALLOC_CHECK_ is set non-zero when running memcheck, then the
overruns that might be detected by MALLOC_CHECK_ would be overruns
on the wrapped blocks which include the red zones. Thus MALLOC_CHECK_
would be checking memcheck, and not the client. This is not useful,
and actually is wasteful. The only possible [documented] advantage
of using MALLOC_CHECK_ and memcheck together, would be if MALLOC_CHECK_
detected duplicate free() in more cases than memcheck because memcheck's
buffer is too small.
Therefore we don't use MALLOC_CHECK_ and valgrind(memcheck) at the
same time.
