Now that stash_push is used in the no verb form of stash, allow
specifying the command line for this form as well. Always use -- to
disambiguate pathspecs from other non-option arguments.
Also make git stash -p an alias for git stash push -p. This allows
users to use git stash -p <pathspec>.

Now that we have stash_push, which accepts pathspec arguments, use
it instead of stash_save in git stash without any additional verbs.
Previously we allowed git stash -- -message, which is no longer allowed
after this patch. Messages starting with a hyphen was allowed since
3c2eb80f, ("stash: simplify defaulting to "save" and reject unknown
options"). However it was never the intent to allow that, but rather it
was allowed accidentally.

While working on a repository, it's often helpful to stash the changes
of a single or multiple files, and leave others alone. Unfortunately
git currently offers no such option. git stash -p can be used to work
around this, but it's often impractical when there are a lot of changes
over multiple files.
Allow 'git stash push' to take pathspec to specify which paths to stash.

Introduce a new git stash push verb in addition to git stash save. The
push verb is used to transition from the current command line arguments
to a more conventional way, in which the message is given as an argument
to the -m option.
This allows us to have pathspecs at the end of the command line
arguments like other Git commands do, so that the user can say which
subset of paths to stash (and leave others behind).

When diff.renames configuration is on (and with Git 2.9 and later,
it is enabled by default, which made it worse), "git stash"
misbehaved if a file is removed and another file with a very
similar content is added.
* jk/stash-disable-renames-internally:
stash: prefer plumbing over git-diff
|
|
When creating a stash, we need to look at the diff between
the working tree and HEAD, and do so using the git-diff
porcelain. Because git-diff enables porcelain config like
renames by default, this causes at least one problem. The
--name-only format will not mention the source side of a
rename, meaning we will fail to stash a deletion that is
part of a rename.
We could fix that case by passing --no-renames, but this is
a symptom of a larger problem. We should be using the
diff-index plumbing here, which does not have renames
enabled by default, and also does not respect any
potentially confusing config options.

Instead of referencing "stash@{n}" explicitly, make it possible to
simply reference as "n". Most users only reference stashes by their
position in the stash stack (what I refer to as the "index" here).
The syntax for the typical stash (stash@{n}) is slightly annoying and
easy to forget, and sometimes difficult to escape properly in a
script. Because of this the capability to do things with the stash by
simply referencing the index is desirable.
This patch includes the superior implementation provided by Øsse Walle
(thanks for that), with a slight change to fix a broken test in the test
suite. I also merged the test scripts as suggested by Jeff King, and
un-wrapped the documentation as suggested by Junio Hamano.

Alternate refs backends might store reflogs somewhere other than
.git/logs. Change most test code that directly accesses .git/logs to
instead use git reflog commands.
There are still a few tests which need direct access to reflogs: to
check reflog permissions, to manually create reflogs from scratch, to
save/restore reflogs, to check the format of raw reflog data, and to
remove not just reflog contents, but the reflogs themselves. All cases
which don't need direct access have been modified.

This reverts commit ed178ef13a26136d86ff4e33bb7b1afb5033f908.
That commit was an attempt to improve the safety of applying
a stash, because the application process may create
conflicted index entries, after which it is hard to restore
the original index state.
Unfortunately, this hurts some common workflows around "git
stash -k", like:
git add -p ;# (1) stage set of proposed changes
git stash -k ;# (2) get rid of everything else
make test ;# (3) make sure proposal is reasonable
git stash apply ;# (4) restore original working tree
If you "git commit" between steps (3) and (4), then this
just works. However, if these steps are part of a pre-commit
hook, you don't have that opportunity (you have to restore
the original state regardless of whether the tests passed or
failed).
It's possible that we could provide better tools for this
sort of workflow. In particular, even before ed178ef, it
could fail with a conflict if there were conflicting hunks
in the working tree and index (since the "stash -k" puts the
index version into the working tree, and we then attempt to
apply the differences between HEAD and the old working tree
on top of that). But the fact remains that people have been
using it happily for a while, and the safety provided by
ed178ef is simply not that great. Let's revert it for now.
In the long run, people can work on improving stash for this
sort of workflow, but the safety tradeoff is not worth it in
the meantime.

The option parser for git-stash stuffs unknown flags into
the $FLAGS variable, where they can be accessed by the
individual commands. However, most commands do not even look
at these extra flags, leading to unexpected results like
this:
$ git stash drop --help
Dropped refs/stash@{0} (e6cf6d80faf92bb7828f7b60c47fc61c03bd30a1)
We should notice the extra flags and bail. Rather than
annotate each command to reject a non-empty $FLAGS variable,
we can notice that "stash show" is the only command that
actually _wants_ arbitrary flags. So we switch the default
mode to reject unknown flags, and let stash_show() opt into
the feature.

If you have staged contents in your index and run "stash
apply", we may hit a conflict and put new entries into the
index. Recovering to your original state is difficult at
that point, because tools like "git reset --keep" will blow
away anything staged. We can make this safer by refusing to
apply when there are staged changes.
It's possible we could provide better tooling here, as "git
stash apply" should be writing only conflicts to the index
(so we know that any stage-0 entries are potentially
precious). But it is the odd duck; most "mergy" commands
will update the index for cleanly merged entries, and it is
not worth updating our tooling to support this use case
which is unlikely to be of interest (besides which, we would
still need to block a dirty index for "stash apply --index",
since that case _would_ be ambiguous).

One of the tests in t3903 wants to make sure that applying a
stash that touches only "file" can still happen even if there
are working tree changes to "other-file". To do so, it adds
"other-file" to the index (since otherwise it is an
untracked file, voiding the purpose of the test).
But as we are about to refactor the dirty-index handling,
and as this test does not actually care about having a dirty
index (only a dirty working tree), let's bump the tracking
of "other-file" into the setup phase, so we can have _just_
a dirty working tree here.

When testing the diff output of "git stash list", we look
for the stash's subject of "WIP on master: $sha1", even
though it's not relevant to the diff output. This makes the
test brittle to refactoring, as any changes to earlier tests
may impact the commit sha1.
Since we don't care about the commit subject here, we can
simply ask stash not to print it.

When you list stashes, you can provide arbitrary git-log
options to change the display. However, adding just "-p"
does nothing, because each stash is actually a merge commit.
This implementation detail is easy to forget, leading to
confused users who think "-p" is not working. We can make
this easier by defaulting to "--first-parent -m", which will
show the diff against the working tree. This omits the
index portion of the stash entirely, but it's simple and it
matches what "git stash show" provides.
People who are more clueful about stash's true form can use
"--cc" to override the "-m", and the "--first-parent" will
then do nothing. For diffs, it only affects non-combined
diffs, so "--cc" overrides it. And for the traversal, we are
walking the linear reflog anyway, so we do not even care
about the parents.

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.

This reverts commit a73653130edd6a8977106d45a8092c09040f9132, 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.

"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.

Finishing touches for the "git rebase --autostash" feature
introduced earlier.
* rr/rebase-stash-store:
rebase: use 'git stash store' to simplify logic
stash: introduce 'git stash store'
stash: simplify option parser for create
stash doc: document short form -p in synopsis
stash doc: add a warning about using create
|
|
* fc/show-non-empty-errors-in-test:
test: test_must_be_empty helper
|
|
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.

- merely a replacement of 'ln -s a b && git add b' by test_ln_s_add

- a test for symbolic link on the file system can be split off (and

Number of columns required for change counts is now computed based on
the maximum number of changed lines instead of being fixed. This means
that usually a few more columns will be available for the filenames
and the graph.
The graph width logic is also modified to include enough space for
"Bin XXX -> YYY bytes".
If changes to binary files are mixed with changes to text files,
change counts are padded to take at least three columns. And the other
way around, if change counts require more than three columns, then
"Bin"s are padded to align with the change count. This way, the +-
part starts in the same column as "XXX -> YYY" part for binary files.
This makes the graph easier to parse visually thanks to the empty
column. This mimics the layout of diff --stat before this change.
Tests and the tutorial are updated to reflect the new --stat output.
This means either the removal of extra padding and/or the addition of
up to three extra characters to truncated filenames. One test is added
to check the graph alignment when a binary file change and text file
change of more than 999 lines are committed together.

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.

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.

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.
