2019-09-20stash: make sure to write refreshed cacheLibravatar Thomas Gummerer1-4/+7
When converting stash into C, calls to 'git update-index --refresh' were replaced with the 'refresh_cache()' function. That is fine as long as the index is only needed in-core, and not re-read from disk. However in many cases we do actually need the refreshed index to be written to disk, for example 'merge_recursive_generic()' discards the in-core index before re-reading it from disk, and in the case of 'apply --quiet', the 'refresh_cache()' we currently have is pointless without writing the index to disk. Always write the index after refreshing it to ensure there are no regressions in this compared to the scripted stash. In the future we can consider avoiding the write where possible after making sure none of the subsequent calls actually need the refreshed cache, and it is not expected to be refreshed after stash exits or it is written somewhere else already.

2019-07-16stash: fix handling removed files with --keep-indexLibravatar Thomas Gummerer1-23/+9
git stash push --keep-index is supposed to keep all changes that have been added to the index, both in the index and on disk. Currently this doesn't behave correctly when a file is removed from the index. Instead of keeping it deleted on disk, --keep-index currently restores the file. Fix that behaviour by using 'git checkout' in no-overlay mode which can faithfully restore the index and working tree. This also simplifies the code. Note that this will overwrite untracked files if the untracked file has the same name as a file that has been deleted in the index.

2019-06-19stash: fix show referencing stash indexLibravatar Thomas Gummerer1-4/+5
In the conversion of 'stash show' to C in dc7bd382b1 ("stash: convert show to builtin", 2019-02-25), 'git stash show <n>', where n is the index of a stash got broken, if n is not a file or a valid revision by itself. 'stash show' accepts any flag 'git diff' accepts for changing the output format. Internally we use 'setup_revisions()' to parse these command line flags. Currently we pass the whole argv through to 'setup_revisions()', which includes the stash index. As the stash index is not a valid revision or a file in the working tree in most cases however, this 'setup_revisions()' call (and thus the whole command) ends up failing if we use this form of 'git stash show'. Instead of passing the whole argv to 'setup_revisions()', only pass the flags (and the command name) through, while excluding the stash reference. The stash reference is parsed (and validated) in 'get_stash_info()' already. This separate parsing also means that we currently do produce the correct output if the command succeeds.

2019-03-21stash: setup default diff output format if necessaryLibravatar Thomas Gummerer1-0/+4
In the scripted 'git stash show' when no arguments are passed, we just pass '--stat' to 'git diff'. When any argument is passed to 'stash show', we no longer pass '--stat' to 'git diff', and pass whatever flags are passed directly through to 'git diff'. By default 'git diff' shows the patch output. So when a user uses 'git stash show --patience', they would be shown the diff as expected, using the patience algorithm. '--patience' in this case only changes the diff algorithm, but does not cause 'git diff' to show the diff by itself. The diff is shown because that's the default behaviour of 'git diff'. In the C version of 'git stash show', we try to emulate that behaviour using the internal diff API. However we forgot to set up the default output format, in case it wasn't set by any of the flags that were passed through. So 'git stash show --patience' in the builtin version of stash would be completely silent, while it would show the diff in the scripted version. The same thing would happen for other flags that only affect the way a patch is displayed, rather than switching to a different output format than the default one. Fix this by setting up the default output format for 'git diff'.

2019-03-12stash: pass pathspec as pointerLibravatar Thomas Gummerer1-30/+38
Passing the pathspec by value is potentially confusing, as the copy is only a shallow copy, so save the overhead of the copy, and pass the pathspec struct as a pointer. In addition use copy_pathspec to copy the pathspec into rev.prune_data, so the copy is a proper deep copy, and owned by the revision API, as that's what the API expects.

Drop the unused prefix parameter in do_drop_stash. We also have an unused "prefix" parameter in the 'create_stash' function, however we leave that in place for symmetry with the other top-level functions.

2019-03-08built-in stash: handle :(glob) pathspecs againLibravatar Johannes Schindelin1-2/+3
When passing a list of pathspecs to, say, `git add`, we need to be careful to use the original form, not the parsed form of the pathspecs. This makes a difference e.g. when calling git stash -- ':(glob)**/*.txt' where the original form includes the `:(glob)` prefix while the parsed form does not. However, in the built-in `git stash`, we passed the parsed (i.e. incorrect) form, and `git add` would fail with the error message: fatal: pathspec '**/*.txt' did not match any files at the stage where `git stash` drops the changes from the worktree, even if `refs/stash` has been actually updated successfully.

2019-03-07tests: add a special setup where stash.useBuiltin is offLibravatar Johannes Schindelin1-1/+4
Add a GIT_TEST_STASH_USE_BUILTIN=false test mode which is equivalent to running with stash.useBuiltin=false. This is needed to spot that we're not introducing any regressions in the legacy stash version while we're carrying both it and the new built-in version. This imitates the equivalent treatment for the built-in rebase in 62c23938fae5 (tests: add a special setup where rebase.useBuiltin is off, 2018-11-14).

2019-03-07stash: optionally use the scripted version againLibravatar Johannes Schindelin1-0/+35
We recently converted the `git stash` command from Unix shell scripts to builtins. Let's end users a way out when they discover a bug in the builtin command: `stash.useBuiltin`. As the file name `git-stash` is already in use, let's rename the scripted backend to `git-legacy-stash`. To make the test suite pass with `stash.useBuiltin=false`, this commit also backports rudimentary support for `-q` (but only *just* enough to appease the test suite), and adds a super-ugly hack to force exit code 129 for `git stash -h`.

2019-03-07stash: convert `stash--helper.c` into `stash.c`Libravatar Paul-Sebastian Ungureanu1-0/+1595
The old shell script `git-stash.sh` was removed and replaced entirely by `builtin/stash.c`. In order to do that, `create` and `push` were adapted to work without `stash.sh`. For example, before this commit, `git stash create` called `git stash--helper create --message "$*"`. If it called `git stash--helper create "$@"`, then some of these changes wouldn't have been necessary. This commit also removes the word `helper` since now stash is called directly and not by a shell script.
