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".

39743cf554 rebase-i: work around Windows CRLF line endings
Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform.  We are seeing
reports that the "read" command in a port of bash to the environment
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.

9a6e4f032e add_submodule_odb: initialize alt_odb list earlier
The add_submodule_odb function tries to add a submodule's
object store as an "alternate". It needs the existing list
to be initialized (from the objects/info/alternates file)
for two reasons:

  1. We look for duplicates with the existing alternate
     stores, but obviously this doesn't work if we haven't
     loaded any yet.

  2. We link our new entry into the list by prepending it to
     alt_odb_list. But we do _not_ modify alt_odb_tail.
     This variable starts as NULL, and is a signal to the
     alt_odb code that the list has not yet been
     initialized.

     We then call read_info_alternates on the submodule (to
     recursively load its alternates), which will try to
     append to that tail, assuming it has been initialized.
     This causes us to segfault if it is NULL.

This rarely comes up in practice, because we will have
initialized the alt_odb any time we do an object lookup. So
you can trigger this only when:

  - you try to access a submodule (e.g., a diff with
    diff.submodule=log)

  - the access happens before any other object has been
    accessed (e.g., because the diff is between the working
    tree and the index)

  - the submodule contains an alternates file (so we try to
    add an entry to the NULL alt_odb_tail)

To fix this, we just need to call prepare_alt_odb at the
start of the function (and if we have already initialized,
it is a noop).

Note that we can remove the prepare_alt_odb call from the
end. It is guaranteed to be a noop, since we will have
called it earlier.

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.

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.

05e625e5bf mailinfo: keep the parsed log message in a strbuf
When mailinfo() is eventually libified, the calling "git am" still
will have to write out the log message in the "msg" file for hooks
and other users of the information, but it does not have to reopen
and reread what it wrote earlier if the function kept it in a strbuf.

This also removes the need for seeking and truncating the output
file when we see a scissors mark in the input, which in turn allows
us to lose two callsites of die_errno().

4933910ab7 mailinfo: handle_commit_msg() shouldn't be called after finding patchbreak
There is a strange "if (!mi->cmitmsg) return 0" at the very beginning
of handle_commit_msg(), but the condition should never trigger, because:

 * The only place cmitmsg is set to NULL is after this function sees
   a patch break, closes the FILE * to write the commit log message
   and returns 1.  This function returns non-zero only from that
   codepath.

 * The caller of this function, upon seeing a non-zero return,
   increments filter_stage, starts treating the input as patch text
   and will never call handle_commit_msg() again.

Replace it with an assert(!mi->filter_stage) to ensure the above
observation will stay to be true.
