f91b2732b3 t1401: test reflog creation for git-symbolic-ref
The current code writes a reflog entry whenever we update a
symbolic ref, but we never test that this is so. Let's add a
test to make sure upcoming refactoring doesn't cause a
regression.

3e4068ed90 symbolic-ref: propagate error code from create_symref()
If create_symref() fails, git-symbolic-ref will still exit
with code 0, and our caller has no idea that the command did
nothing.

This appears to have been broken since the beginning of time
(e.g., it is not a regression where create_symref() stopped
calling die() or something similar).

4d2a3646d1 filter-branch: deal with object name vs. pathname ambiguity in tree-filter
'git filter-branch' fails complaining about an ambiguous argument, if
a tree-filter renames a path and the new pathname happens to match an
existing object name.

After the tree-filter has been applied, 'git filter-branch' looks for
changed paths by running:

  git diff-index -r --name-only --ignore-submodules $commit

which then, because of the lack of disambiguating double-dash, can't
decide whether to treat '$commit' as revision or path and errors out.

Add that disambiguating double-dash after 'git diff-index's revision
argument to make sure that '$commit' is interpreted as a revision.

c26f70ceb3 bash prompt: indicate dirty index even on orphan branches
__git_ps1() doesn't indicate dirty index while on an orphan branch.

To check the dirtiness of the index, __git_ps1() runs 'git diff-index
--cached ... HEAD', which doesn't work on an orphan branch,
because HEAD doesn't point to a valid commit.

Run 'git diff ... --cached' instead, as it does the right thing both
on valid and invalid HEAD, i.e. compares the index to the existing
HEAD in the former case and to the empty tree in the latter.  This
fixes the two failing tests added in the first commit of this series.

The dirtiness of the worktree is already checked with 'git diff' and
is displayed correctly even on an orphan branch.

a30d11ebdf bash prompt: test dirty index and worktree while on an orphan branch
There is only a single test exercising the dirty state indicator on an
orphan branch, and in that test neither the index nor the worktree are
dirty.

Add two failing tests to check the dirty state indicator while either
the index is dirty or while both the index and the worktree are dirty
on an orphan branch, and to show that the dirtiness of the index is
not displayed in these cases (the fourth combination, i.e. clean index
and dirty worktree are impossible on an orphan branch).  Update the
existing dirty state indicator on clean orphan branch test to match
the style of the two new tests, most importantly to use 'git checkout
--orphan' instead of cd-ing into a repository that just happens to be
empty and clean.

681390b3f6 t5813: avoid creating urls that break on cygwin
When passed an ssh:// url, git strips ssh://host from the url but does
not remove leading slashes from the path. So when this test used
ssh://remote//path/to/pwd, the path accessed by our fake SSH is
//path/to/pwd, which cygwin interprets as a UNC path, causing the test
to fail.

We may want to actually fix this in git itself, making it remove extra
slashes from urls before feeding them to transports or helpers, but
that's for another topic as it could cause regressions.

af65f68cdf allow hooks to ignore their standard input stream
Since ec7dbd145 (receive-pack: allow hooks to ignore its
standard input stream) the pre-receive and post-receive
hooks ignore SIGPIPE. Do the same for the remaining hooks
pre-push and post-rewrite, which read from standard input.
The same arguments for ignoring SIGPIPE apply.

Include test by Jeff King which checks that SIGPIPE does not
cause pre-push hook failure. With the use of git update-ref
--stdin it is fast enough to be enabled by default.

baf0a3e47d wt-status: avoid building bogus branch name with detached HEAD
If we're on a detached HEAD then wt_shortstatus_print_tracking() takes
the string "HEAD (no branch)", translates it, skips the first eleven
characters and passes the result to branch_get(), which returns a bogus
result and accesses memory out of bounds in order to produce it.
Somehow stat_tracking_info(), which is passed that result, does the
right thing anyway, i.e. it finds that there is no base.

Avoid the bogus results and memory accesses by checking for HEAD first
and exiting early in that case.  This fixes t7060 with --valgrind.

cfe2d4be91 difftool: ignore symbolic links in use_wt_file
The caller is preparing a narrowed-down copy of the working tree and
this function is asked if the path should be included in that copy.
If we say yes, the path from the working tree will be either symlinked
or copied into the narrowed-down copy.

For any path that is a symbolic link, the caller later fixes up the
narrowed-down copy by unlinking the path and replacing it with a
regular file it writes out that mimics the way how "git diff"
compares symbolic links.

Let's answer "no, you do not want to copy/symlink the working tree
file" for all symbolic links from this function, as we know the
result will not be used because it will be overwritten anyway.

Incidentally, this also stops the function from feeding a symbolic
link in the working tree to hash-object, which is a wrong thing to
do to begin with. The link may be pointing at a directory, or worse
may be dangling (both would be noticed as an error).  Even if the
link points at a regular file, hashing the contents of a file that
is pointed at by the link is not correct (Git hashes the contents of
the link itself, not the pointee).

e34f80278e merge-file: clamp exit code to maximum 127
Git-merge-file is documented to return one of three exit
codes:

  - zero means the merge was successful

  - a negative number means an error occurred

  - a positive number indicates the number of conflicts

Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).

This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).

Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

however does not strip the CRLF at the end, not adjusting for the
same convention on the platform.

This breaks the recently added sanity checks for the insn sheet fed
to "rebase -i"; instead of an empty line (hence nothing in $command),
the script was getting a lone CR in there.

Special case a lone CR and treat it the same way as an empty line to
work this around.

This patch (also) passes the test with Git for Windows, where the
issue was seen first.

72fac66bca merge: detect delete/modechange conflict
If one side deletes a file and the other changes its
content, we notice and report a conflict. However, if
instead of changing the content, we change only the mode,
the merge does not notice (and the mode change is silently
dropped).

The trivial index merge notices the problem and correctly
leaves the conflict in the index, but both merge-recursive
and merge-one-file will silently resolve this in favor of
the deletion.  In many cases that is a sane resolution, but
we should be punting to the user whenever there is any
question. So let's detect and treat this as a conflict (in
both strategies).

f78d1fe208 t6031: generalize for recursive and resolve strategies
This script tests the filemode handling of merge-recursive,
but we do not test the same thing for merge-resolve. Let's
generalize the script a little:

  1. Break out the setup steps for each test into a separate
     snippet.

  2. For each test, run it twice; once with "-s recursive"
     and once with "-s resolve". We can avoid repeating
     ourselves by adding a function.

  3. Since we have a nice abstracted function, we can make
     our tests more thorough by testing both directions
     (change on "ours" versus "theirs").

This improves our test coverage, and will make this the
place to add more tests related to merging mode changes.

6f50833e98 t6031: move triple-rename test to t3030
The t6031 test was introduced to check filemode handling of
merge-recursive. Much later, an unrelated test was tacked on
to look at renames and d/f conflicts. This test does not
depend on anything that happened before (it actually blows
away any existing content in the test repo). Let's move it
to t3030, where there are more related tests.

29abb33978 add: simplify -u/-A without pathspec
Since Git 2.0, "add -u" and "add -A" run from a subdirectory without
any pathspec mean "everything in the working tree" (before 2.0, they
were limited to the current directory).  The limiting to the current
directory was implemented by inserting "." to the command line when
the end user did not give us any pathspec.  At 2.0, we updated the
code to insert ":/" (instead of '.') to consider everything from the
top-level, by using a pathspec magic "top".

The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be".  The parse_pathspec() then would give
us a pathspec that matches everything and all is well.

Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs).  The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.
