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.

23a32ffe80 stash: fix incorrect quoting in cleanup of temporary files
The * was inside the quotes, so that the pattern was never expanded and the
temporary files were never removed. As a consequence, 'stash -p' left a
.git-stash-*-patch file in $GIT_DIR. Other code paths did not leave files
behind because they removed the temporary file themselves, at least in
non-error paths.

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.

Currently git-stash uses `git rev-parse --no-revs -- "$@"` to set its
FLAGS variable.  This is the same as `FLAGS="-- $@"`.  It should use
`git rev-parse --no-revs --flags "$@"`, but that eats any "-q" or

a9bf09e19d detached-stash: simplify git stash show
This commit refactors git stash show to make use of the assert_stash_like function.

git show now dies if the presented argument is non-stash-like.

Previous behaviour was to tolerate commits that were not even stash-like.

Previously, git stash show would accept stash-like arguments, but
only if there was a stash on the stack.

Now, git stash accepts stash-like arguments always and only fails
if no stash-like argument is specified and there is no stash stack.

In particular, a stash is only required if an argument isn't specified
and the stash is only dropped if a stash entry reference was
specified or implied.

The implementation has been simplified by taking advantage of

parse_flags_and_rev().

f276872d89 detached-stash: refactor git stash pop implementation
git stash pop is abstracted into its own implementation function - pop_stash.

The behaviour is changed so that git stash pop fails early if the
the specified stash reference does not exist or does not refer to
an extant entry in the reflog of the reference stash.

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).

ef763129d1 detached-stash: introduce parse_flags_and_revs function
Introduce parse_flags_and_revs. This function requires that
there is at most one stash-like revision parameter and
zero or more flags.

It knows how to parse -q,--quiet and --index flags, but leaves
other flags parsed.

Specified revisions are checked to see that they are at
least stash-like (meaning: they look like something created
by git stash save or git stash create).

If this is so, then IS_STASH_LIKE is initialized to a non-empty value.

If the specified revision also looks like a stash log entry reference,
then IS_STASH_REF is initialized to a non-empty value.

References of the form ref@{spec} are required to precisely identify
an individual commit.

If no reference is specified, stash@{0} is assumed.

Once the specified reference is validated to be at least stash_like
an ensemble of derived variables, (w_commit, w_tree, b_commit, etc)
is initialized with a single call to git rev-parse.

Repeated calls to parse_flags_and_rev() avoid repeated calls
to git rev-parse if the specified arguments have already been
parsed.

Subsequent patches in the series modify the existing
git stash subcommands to make use of these functions
as appropriate.

An ensemble of supporting functions that make use of the state
established by parse_flags_and_rev(). These are described below:

The ancillary functions are:

is_stash_like(): which can be used to test
whether a specified commit looks like a commit created with
git stash save or git stash create.

assert_stash_like(): which can be used by
commands that misbehave unless their arguments stash-like.

is_stash_ref(): which checks whether an argument
is valid stash reference(e.g. is of the form
['refs/']stash['@{'something'}])

assert_stash_ref(): which can be used by commands
that misbehave unless their arguments are both stash-like and
refer to valid stash entries.

7aa5d43cc6 stash: Don't overwrite files that have gone from the index
The use of git add -u in create_stash isn't always complete. In
particular, if a file has been removed from the index but changed in the
work tree it will not be added to the stash's saved work tree tree
object. When stash then resets the work tree to match HEAD, any changes
will be lost.

To be complete, any work tree file which differs from HEAD needs to be
saved, regardless of whether it still appears in the index or not.

This is achieved with a combination of a diff against HEAD and a call to
update-index with an explicit list of paths that have changed.

Instead of adding --no-decorate to the log command line,
let's just use the rev-list plumbing interface instead,
which does the right thing.

git-submodule has a similar call. Since it just counts the
commit lines, nothing is broken, but let's switch it, too,

460ccd0e19 stash pop: remove 'apply' options during 'drop' invocation
The 'git stash pop' option parsing used to remove the first argument
in --index mode.  At the time this was implemented, this first
argument was always --index.  However, since the invention of the -q
option in fcdd0e9 (stash: teach quiet option, 2009-06-17) you can
cause an internal invocation of

  git stash drop --index

by running

  git stash pop -q --index

which then of course fails because drop doesn't know --index.

To handle this, instead let 'git stash apply' decide what the future
argument to 'drop' should be.

Warning: this means that 'git stash apply' must parse all options that
'drop' can take, and deal with them in the same way.  This is
currently true for its only option -q.

3c2eb80fe3 stash: simplify defaulting to "save" and reject unknown options
With the earlier DWIM patches, certain combination of options defaulted
to the "save" command correctly while certain equally valid combination
did not.  For example, "git stash -k" were Ok but "git stash -q -k" did
not work.

This makes the logic of defaulting to "save" much simpler. If there are no
non-flag arguments, it is clear that there is no command word, and we
default to "save" subcommand.  This rule prevents "git stash -q apply"
from quietly creating a stash with "apply" as the message.

This also teaches "git stash save" to reject an unknown option.  This is
to keep a mistyped "git stash save --quite" from creating a stash with a
message "--quite", and this safety is more important with the new logic
to default to "save" with any option-looking argument without an explicit
comand word.

[jc: this is based on Matthieu's 3-patch series, and a follow-up
discussion, and he and Peff take all the credit; if I have introduced bugs
while reworking, they are mine.]

This adds a hunk-based mode to git-stash.  You can select hunks from
the difference between HEAD and worktree, and git-stash will build a
stash that reflects these changes.  The index state of the stash is
the same as your current index, and we also let --patch imply
--keep-index.

Note that because the selected hunks are rolled back from the worktree
but not the index, the resulting state may appear somewhat confusing
if you had also staged these changes.  This is not entirely
satisfactory, but due to the way stashes are applied, other solutions
would require a change to the stash format.

f39d6ee2aa Documentation: mention 'git stash pop --index' option explicitly
'git stash pop' supports the '--index' option since its initial
implementation (bd56ff54, git-stash: add new 'pop' subcommand,
2008-02-22), but its documentation does not mention it explicitly.
Moreover, both the usage shown by 'git stash -h' and the synopsis
section in the man page imply that 'git stash pop' does not have an
'--index' option.

First, this patch corrects the usage and the synopsis section.

Second, the patch moves the description of the '--index' option to the
'git stash pop' section in the documentation, and refers to it from
the 'git stash apply' section.  This way it follows the intentions of
commit d1836637 (Documentation: teach stash/pop workflow instead of

875471c510 git-stash.sh: fix flawed fix of invalid ref handling (commit da65e7c1)
The referenced commit tried to fix a flaw in stash's handling of a user
supplied invalid ref. i.e. 'git stash apply fake_ref@{0}' should fail
instead of applying stash@{0}. But, it did so in a naive way by avoiding the
use of the --default option of rev-parse, and instead manually supplied the
default revision if the user supplied an empty command line. This prevented
a common usage scenario of supplying flags on the stash command line (i.e.
non-empty command line) which would be parsed by lower level git commands,
without supplying a specific revision. This should fall back to the default
revision, but now it causes an error. e.g. 'git stash show -p'

The correct fix is to use the --verify option of rev-parse, which fails
properly if an invalid ref is supplied, and still allows falling back to a
default ref when one is not supplied.

Convert stash-drop to use --verify while we're at it, since specifying
multiple revisions for any of these commands is also an error and --verify
makes it so.

da65e7c133 git-stash.sh: don't default to refs/stash if invalid ref supplied
apply_stash() and show_stash() each call rev-parse with
'--default refs/stash' as an argument. This option causes rev-parse to
operate on refs/stash if it is not able to successfully operate on any
element of the command line. This includes failure to supply a "valid"
revision. This has the effect of causing 'stash apply' and 'stash show'
to operate as if stash@{0} had been supplied when an invalid revision is
supplied.

e.g. 'git stash apply stash@{1}' would fall back to
     'git stash apply stash@{0}'

This patch modifies these two functions so that they avoid using the
--default option of rev-parse.

a5ab00c5d2 git-stash: improve synopsis in help and manual page
"git stash -h" showed some incomplete and ugly usage information.
For example, the useful "--keep-index" option for "save" or the "--index"
option for  "apply" were not shown. Also in the documentation synopsis they
were not shown, so that there is no incentive to scroll down and even see
that such options exist.

This patch improves the git-stash synopsis in the documentation by
mentioning that further options to the stash commands and then copies
this synopsis to the usage information string of git-stash.sh.

For the latter, the dashless git command string has to be inserted on the
second and the following usage lines. The code of this is taken from
git-sh-setup so that all lines will show the command string.

Note that the "create" command is not advertised at all now, because
it was not mentioned in git-stash.txt.

'git stash save' saves local modifications to a new stash, and runs 'git
reset --hard' to revert them to a clean index and work tree.  When the
'--keep-index' option is specified, after that 'git reset --hard' the
previous contents of the index is restored and the work tree is updated
to match the index.  This option is useful if the user wants to commit
only parts of his local modifications, but wants to test those parts
before committing.

cbeaccc316 Fix git-stash apply --index
Two bugs that made the command practically unusable were fixed
with this.

 - A stash created with a clean index does not have any
   difference between the base tree and the index tree.
   Trying to apply the diff between them to the index would
   error out with "No changes".  Even when the user asked to
   unstash with --index, do not bother with --index action if
   the base tree and the index tree match.

 - After successfully performing the working tree merge, the
   index was reloaded from an earlier state of unstashed index
   with "read-tree"; this left all the paths cache dirty.  By
   moving the call to git-status after this read-tree, match the
   cached stat information in the index.
