d0ea45bfc7 git-stash.sh: use the $( ... ) construct for command substitution
The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.

The backquoted form is the traditional method for command
substitution, and is supported by POSIX.  However, all but the
simplest uses become complicated quickly.  In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.

The patch was generated by:

for _f in $(find . -name "*.sh")
do
   sed -i 's@`\(.*\)`@$(\1)@g' ${_f}
done

and then carefully proof-read.

2a07e4374c stash: handle specifying stashes with $IFS
When trying to pop/apply a stash specified with an argument
containing IFS whitespace, git-stash will throw an error:

    $ git stash pop 'stash@{two hours ago}'
    Too many revisions specified: stash@{two hours ago}

This happens because word splitting is used to count non-option
arguments. Make use of rev-parse's --sq option to quote the arguments
for us to ensure a correct count. Add quotes where necessary.

Also add a test that verifies correct behaviour.

c1ebd90c83 Revert "git stash: avoid data loss when "git stash save" kills a directory"
This reverts commit a73653130e, as it
has been reported that "ls-files --killed" is too time-consuming in
a deep directory with too many untracked crufts (e.g. $HOME/.git
tracking only a few files).

We'd need to revisit it later but "ls-files --killed" needs to be
optimized before it happens.

a73653130e git stash: avoid data loss when "git stash save" kills a directory
"stash save" is about saving the local change to the working tree,
but also about restoring the state of the last commit to the working
tree.  When a local change is to turn a non-directory to a directory,
in order to restore the non-directory, everything in the directory
needs to be removed.

Which is fine when running "git stash save --include-untracked",
but without that option, untracked, newly created files in the
directory will have to be discarded, if the state you are restoring
to has a non-directory at the same path as the directory.

Introduce a safety valve to fail the operation in such case, using
the "ls-files --killed" which was designed for this exact purpose.

The "stash save" is stopped when untracked files need to be
discarded because their leading path ceased to be a directory, and
the user is required to pass --force to really have the data
removed.

bd514cada4 stash: introduce 'git stash store'
save_stash() contains the logic for doing two potentially independent
operations; the first is preparing the stash merge commit, and the
second is updating the stash ref/ reflog accordingly.  While the first
operation is abstracted out into a create_stash() for callers to access
via 'git stash create', the second one is not.  Fix this by factoring
out the logic for storing the stash into a store_stash() that callers
can access via 'git stash store'.

Like create, store is not intended for end user interactive use, but for
callers in other scripts.  We can simplify the logic in the
rebase.autostash feature using this new subcommand.

743bf6d8b0 stash: invoke rerere in case of conflict
"stash apply" directly calls a backend merge function which does not

rerere state is left behind from previous merges.

Invoke rerere explicitly when we encounter a conflict during stash
apply.  This turns the test introduced by the previous commit to
succeed.

44df2e2970 stash: Don't fail if work dir contains file named 'HEAD'
When performing a plain "git stash" (without --patch), git-diff would fail
with "fatal: ambiguous argument 'HEAD': both revision and filename". The
output was piped into git-update-index, masking the failed exit status.
The output is now sent to a temporary file (which is cleaned up by
existing code), and the exit status is checked. The "HEAD" arg to the
git-diff invocation has been disambiguated too, of course.

In patch mode, "git stash -p" would fail harmlessly, leaving the working
dir untouched. Interactive adding is fine, but the resulting tree was
diffed with an ambiguous 'HEAD' argument.

Use >foo (no space) when redirecting output.

In t3904, checks and operations on each file are in the order they'll
appear when interactively staging.

In t3905, fix a bug in "stash save --include-untracked -q is quiet": The
redirected stdout file was considered untracked, and so was removed from
the working directory. Use test path helper functions where appropriate.

7474b8b452 git-stash: remove untracked/ignored directories when stashed
The two new stash options --include-untracked and --all do not remove the
untracked and/or ignored files that are stashed if those files reside in
a subdirectory. e.g. the following sequence fails:

   mkdir untracked &&
   echo hello >untracked/file.txt &&
   git stash --include-untracked &&
   test ! -f untracked/file.txt

Within the git-stash script, git-clean is used to remove the
untracked/ignored files, but since the -d option was not supplied, it does
not remove directories.

So, add -d to the git-clean arguments, and update the tests to test this
functionality.

787513027a stash: Add --include-untracked option to stash and remove all untracked files
The --include-untracked option acts like the normal "git stash save" but
also adds all untracked files in the working directory to the stash and then
calls "git clean --force --quiet" to restore the working directory to a
pristine state.

This is useful for projects that need to run release scripts. With this
option, the release scripts can be from the main working directory so one
does not have to maintain a "clean" directory in parallel just for
releasing. Basically the work-flow becomes:

   $ git tag release-1.0
   $ git stash --include-untracked
   $ make release
   $ git clean -f
   $ git stash pop

"git stash" alone is not enough in this case--it leaves untracked files
lying around that might mess up a release process that expects everything to
be very clean or might let a release succeed that should actually fail (due
to a new source file being created that hasn't been committed yet).

e0e2a9cbfa stash: drop dirty worktree check on apply
Before we apply a stash, we make sure there are no changes
in the worktree that are not in the index. This check dates
back to the original git-stash.sh, and is presumably
intended to prevent changes in the working tree from being
accidentally lost during the merge.

However, this check has two problems:

  1. It is overly restrictive. If my stash changes only file
     "foo", but "bar" is dirty in the working tree, it will
     prevent us from applying the stash.

  2. It is redundant. We don't touch the working tree at all
     until we actually call merge-recursive. But it has its
     own (much more accurate) checks to avoid losing working
     tree data, and will abort the merge with a nicer
     message telling us which paths were problems.

So we can simply drop the check entirely.

59d418fe10 stash: fix accidental apply of non-existent stashes
Once upon a time, "git rev-parse ref@{9999999}" did not
generate an error. Therefore when we got an invalid stash
reference in "stash apply", we could end up not noticing
until quite late.  Commit b0f0ecd (detached-stash: work
around git rev-parse failure to detect bad log refs,
2010-08-21) handled this by checking for the "Log for stash
has only %d entries" warning on stderr when we validated the
ref.

A few days later, e6eedc3 (rev-parse: exit with non-zero
status if ref@{n} is not valid., 2010-08-24) fixed the
original issue. That made the extra stderr test superfluous,
but also introduced a new bug. Now the early call to:

  git rev-parse --symbolic "$@"

fails, but we don't notice the exit code. Worse, its empty
output means we think the user didn't provide us a ref, and
we try to apply stash@{0}.

This patch checks the rev-parse exit code and fails early in
the revision parsing process. We can also get rid of the
stderr test; as a bonus, this means that "stash apply" can
now run under GIT_TRACE=1 properly.

3ba2e8653c stash: copy the index using --index-output instead of cp -p
'git stash create' must operate with a temporary index. For this purpose,
it used 'cp -p' to create a copy. -p is needed to preserve the timestamp
of the index file. Now Jakob Pfender reported a certain combination of
a Linux NFS client, OpenBSD NFS server, and cp implementation where this
operation failed.

Luckily, the first operation in git-stash after copying the index is to
call 'git read-tree'. Therefore, use --index-output instead of 'cp -p'
to write the copy of the index.

--index-output requires that the specified file is on the same volume as
the source index, so that the lock file can be rename()d. For this reason,
the name of the temporary index is constructed in a way different from the
other temporary files. The code path of 'stash -p' also needs a temporary
index, but we do not use the new name because it does not depend on the
same precondition as --index-output.

26b59b4812 git stash: show status relative to current directory
git status shows modified paths relative to current directory, so it's
possible to copy&paste them directly, even if you're in a subdirectory.

But "git stash apply" always shows status from root of git repository.
This is misleading because you can't use the paths without modifications.

This is caused by changing directory to root of repository at the
beginning of git stash.

This patch makes git stash show status relative to current directory.
Instead of removing the "cd to toplevel", which would affect whole
script and might have other side-effects, the fix is to change directory
temporarily back to original dir just before displaying status.

This fixes the case where the apply succeeds, but the drop fails.
Previously this caused caused git stash pop to exit with a non-zero exit code
and a dirty tree.

Now, git stash pop fails with a non-zero exit code, but the working
tree is not modified.

92e39e4454 detached-stash: simplify stash_drop
Previously, git stash drop would fail noisily while executing git reflog
delete if the specified revision was not a stash reference.

Now, git stash drop fails with an error message which more precisely
indicates the reason for failure.

Furthermore, git stash drop will now fail with a non-zero status code
if stash@{n} specifies a stash log entry that does not actually exist.

This change in behaviour is achieved by delegating argument parsing
to the common parse_flags_and_rev() function (via a call to
assert_stash_ref).

064ed100b2 detached-stash: simplify stash_apply
The implementation of stash_apply() is simplified to take
advantage of the common parsing function parse_flags_and_rev().

b0f0ecd979 detached-stash: work around git rev-parse failure to detect bad log refs
This commit is required because git rev-parse in 1.7.2 does not correctly
indicate invalid log references using a non-zero status code.

We use a proxy for the condition (non-empty error output) as
a substitute. This commit can be reverted when, and if, rev-parse
is fixed to indicate invalid log references with a status code.
