Migrate those run-command API users that assign directly to the "argv"
member to use a strvec_pushv() of "args" instead.
In these cases it did not make sense to further refactor these
callers, e.g. daemon.c could be made to construct the arguments closer
to handle(), but that would require moving the construction from its
cmd_main() and pass "argv" through two intermediate functions.
It would be possible for a change like this to introduce a regression
if we were doing:
cp.argv = argv;
argv[1] = "foo";
And changed the code, as is being done here, to:
strvec_pushv(&cp.args, argv);
argv[1] = "foo";
But as viewing this change with the "-W" flag reveals none of these
functions modify variable that's being pushed afterwards in a way that
would introduce such a logic error.

"git add -i" failed to honor custom colors configured to show
patches, which has been corrected.
* js/add-i-color-fix:
add -i: verify in the tests that colors can be overridden
add -p: prefer color.diff.context over color.diff.plain
add -i (Perl version): color header to match the C version
add -i (built-in): use the same indentation as the Perl version
add -p (built-in): do not color the progress indicator separately
add -i (built-in): use correct names to load color.diff.* config
add -i (built-in): prevent the `reset` "color" from being configured
add -i: use `reset_color` consistently
add -p (built-in): imitate `xdl_format_hunk_hdr()` generating hunk headers
add -i (built-in): send error messages to stderr
add -i (built-in): do show an error message for incorrect inputs
|
|
The Perl version of this command colors the progress indicator and the
prompt message in one go.
Let's do the same in the built-in version so that the same upcoming test
(which will compare the output of `git add -p` against a known-good
version) will pass both for the Perl version as well as for the built-in
version.

A popular way of partially staging a new file is to run `git add -N
<path>` and then use the hunk editing of `git add -p` to select the
part of the file that the user wishes to stage. Since
85953a3187 ("diff-files --raw: show correct post-image of
intent-to-add files", 2020-07-01) this has stopped working as
intent-to-add paths are now show as new files rather than changes to
an empty blob and `git apply` refused to apply a creation patch for a
path that was marked as intent-to-add. 7cfde3fa0f ("apply: allow "new
file" patches on i-t-a entries", 2020-08-06) fixed the problem with
apply but it still wasn't possible to edit the added hunk properly.
2c8bd8471a ("checkout -p: handle new files correctly", 2020-05-27)
had previously changed `add -p` to handle new files but it did not
implement patch editing correctly. The perl version simply forbade
editing and the C version opened the editor with the full diff rather
that just the hunk which meant that the user had to edit the hunk
header manually to get it to work.
The root cause of the problem is that added files store the diff header
with the hunk data rather than separating the two as we do for other
changes. Changing added files to store the diff header separately
fixes the editing problem at the expense of having to special case
empty additions as they no longer have any hunks associated with them,
only the diff header.
The changes move some existing code into a conditional changing the
indentation, they are best viewed with
--color-moved-ws=allow-indentation-change (or --ignore-space-change
works well to get an overview of the changes)

After applying hunks to a file with "add -p", the C patch_update_file()
function tries to refresh the index (just like the perl version does).
We can only refresh the index if we're able to read it in, so we first
check the return value of repo_read_index(). But unlike many functions,
where "0" is success, that function is documented to return the number
of entries in the index. Hence we should be checking for success with a
non-negative return value.
Neither the tests nor any users seem to have noticed this, probably due
to a combination of:
- this affects only the C version, which is not yet the default
- following it up with any porcelain command like "git diff" or "git
commit" would refresh the index automatically.
But you can see the problem by running the plumbing "git diff-files"
immediately after "add -p" stages all hunks. Running the new test with
GIT_TEST_ADD_I_USE_BUILTIN=1 fails without the matching code change.

"git add -p" update.
* pw/add-p-allowed-options-fix:
add -p: fix checking of user input
add -p: use ALLOC_GROW_BY instead of ALLOW_GROW
|
|
When a file has been deleted the C version of add -p allows the user
to edit a hunk even though 'e' is not in the list of allowed
responses. (I think 'e' is disallowed because if the file is edited it
is no longer a deletion and we're not set up to rewrite the diff
header).
The invalid response was allowed because the test that determines
whether to display 'e' was not duplicated correctly in the code that
processes the user's choice. Fix this by using flags that are set when
constructing the prompt and checked when processing the user's choice
rather than repeating the check itself.

The argv_array API is useful for not just managing argv but any
"vector" (NULL-terminated array) of strings, and has seen adoption
to a certain degree. It has been renamed to "strvec" to reduce the
barrier to adoption.
* jk/strvec:
strvec: rename struct fields
strvec: drop argv_array compatibility layer
strvec: update documention to avoid argv_array
strvec: fix indentation in renamed calls
strvec: convert remaining callers away from argv_array name
strvec: convert more callers away from argv_array name
strvec: convert builtin/ callers away from argv_array name
quote: rename sq_dequote_to_argv_array to mention strvec
strvec: rename files from argv-array to strvec
argv-array: rename to strvec
argv-array: use size_t for count and alloc
|
|
The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").
Note that we have to update all of the callers immediately. Playing
tricks with the preprocessor is hard here, because we wouldn't want to
rewrite unrelated tokens.

Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts remaining files from the first half of the alphabet,
to keep the diff to a manageable size.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
and then selectively staging files with "git add '[abcdefghjkl]*'".
We'll deal with any indentation/style fallouts separately.

"git checkout -p" did not handle a newly added path at all.
* js/checkout-p-new-file:
checkout -p: handle new files correctly
|
|
The original patch selection code was written for `git add -p`, and the
fundamental unit on which it works is a hunk.
We hacked around that to handle deletions back in 24ab81ae4d
(add-interactive: handle deletion of empty files, 2009-10-27). But `git
add -p` would never see a new file, since we only consider the set of
tracked files in the index.
However, since the same machinery was used for `git checkout -p` &
friends, we can see new files.
Handle this case specifically, adding a new prompt for it that is
modeled after the `deleted file` case.
This also fixes the problem where added _empty_ files could not be
staged via `git checkout -p`.

There are quite a few code locations (e.g. `git clean --interactive`)
where Git asks the user for an answer. In preparation for fixing a bug
shared by all of them, and also to DRY up the code, let's refactor it.
Please note that most of these callers trimmed white-space both at the
beginning and at the end of the answer, instead of trimming only the
end (as the caller in `add-patch.c` does).
Therefore, technically speaking, we change behavior in this patch. At
the same time, it can be argued that this is actually a bug fix.

The Perl version of `git add -p` supports this config setting to allow
users to input commands via single characters (as opposed to having to
press the <Enter> key afterwards).
This is an opt-in feature because it requires Perl packages
(Term::ReadKey and Term::Cap, where it tries to handle an absence of the
latter package gracefully) to work. Note that at least on Ubuntu, that
Perl package is not installed by default (it needs to be installed via
`sudo apt-get install libterm-readkey-perl`), so this feature is
probably not used a whole lot.
In C, we obviously do not have these packages available, but we just
introduced `read_single_keystroke()` that is similar to what
Term::ReadKey provides, and we use that here.

needs to know in order to act as the work horse for `git checkout -p`.
Apart from the minor changes (slightly reworded messages, different
`diff` and `apply --check` invocations), it requires a new function to
actually apply the changes, as `git checkout -p` is a bit special in

The Perl script backing `git add -p` is used not only for that command,
but also for `git stash -p`, `git reset -p` and `git checkout -p`.
In preparation for teaching the C version of `git add -p` to support
also the latter commands, let's abstract away what is "stage" specific
into a dedicated data structure describing the differences between the
patch modes.
Finally, please note that the Perl version tries to make sure that the
diffs are only generated for the modified files. This is not actually
necessary, as the calls to Git's diff machinery already perform that
work, and perform it well. This makes it unnecessary to port the
`FILTER` field of the `%patch_modes` struct, as well as the

Just like `git add --edit` allows the user to edit the diff before it is
being applied to the index, this feature allows the user to edit the
diff *hunk*.
Naturally, it gets a bit more complicated here because the result has
to play well with the remaining hunks of the overall diff. Therefore,
we have to do a loop in which we let the user edit the hunk, then test
whether the result would work, and if not, drop the edits and let the
user decide whether to try editing the hunk again.
Note: in contrast to the Perl version, we use the same diff
"coalescing" (i.e. merging overlapping hunks into a single one) also for
the check after editing, and we introduce a new flag for that purpose
that asks the `reassemble_patch()` function to pretend that all hunks
were selected for use.
This allows us to continue to run `git apply` *without* the
`--allow-overlap` option (unlike the Perl version), and it also fixes
two known breakages in `t3701-add-interactive.sh` (which we cannot mark
as resolved so far because the Perl script version is still the default
and continues to have those breakages).

Note: we cannot simply modify the hunks while merging them; Once we
implement hunk editing, we will call `reassemble_patch()` whenever a
hunk is edited, therefore we must not modify the hunks (because the user
might e.g. hit `K` and change their mind whether to stage the previous
hunk).

If this developer's workflow is any indication, then this is *the* most
useful feature of Git's interactive `add `command.
Note: once again, this is not a verbatim conversion from the Perl code
to C: the `hunk_splittable()` function, for example, essentially did all
the work of splitting the hunk, just to find out whether more than one
hunk would have been the result (and then tossed that result into the
trash). In C we instead count the number of resulting hunks (without
actually doing the work of splitting, but just counting the transitions
from non-context lines to context lines), and store that information
with the hunk, and we do that *while* parsing the diff in the first
place.
Another deviation: the built-in `git add -p` was designed with a single
strbuf holding the diff (and another one holding the colored diff, if
that one was asked for) in mind, and hunks essentially store just the
start and end offsets pointing into that strbuf. As a consequence, when
we split hunks, we now use a special mode where the hunk header is
generated dynamically, and only the rest of the hunk is stored using
such start/end offsets. This way, we also avoid the frequent
formatting/re-parsing of the hunk header of the Perl version.

This imitates the way the Perl version treats mode changes: it offers

In contrast to the Perl version, we make use of the fact that the mode
line is the first hunk, and explicitly strip out that line from the diff
header if that "hunk" was not selected to be applied, and skipping that
hunk while coalescing the diff. The Perl version plays some kind of diff
line lego instead.

When skipping a hunk that adds a different number of lines than it
removes, we need to adjust the subsequent hunk headers of non-skipped
hunks: in pathological cases, the context is not enough to determine
precisely where the patch should be applied.
This problem was identified in 23fea4c240 (t3701: add failing test for
pathological context lines, 2018-03-01) and fixed in the Perl version in
fecc6f3a68 (add -p: adjust offsets of subsequent hunks when one is
skipped, 2018-03-01).
And this patch fixes it in the C version of `git add -p`.
In contrast to the Perl version, we try to keep the extra text on the
hunk header (which typically contains the signature of the function
whose code is changed in the hunk) intact.
Note: while the C version does not support staging mode changes at this
stage, we already prepare for this by simply skipping the hunk header if
both old and new offset is 0 (this cannot happen for regular hunks, and
we will use this as an indicator that we are looking at a special hunk).
Likewise, we already prepare for hunk splitting by handling the absence
of extra text in the hunk header gracefully: only the first split hunk
will have that text, the others will not (indicated by an empty extra
text start/end range). Preparing for hunk splitting already at this
stage avoids an indentation change of the entire hunk header-printing
block later, and is almost as easy to review as without that handling.

Just like the Perl version, we now generate two diffs if `color.diff` is
set: one with and one without color. Then we parse them in parallel and
record which hunks start at which offsets in both.
Note that this is a (slight) deviation from the way the Perl version did
it: we are no longer reading the output of `diff-files` line by line
(which is more natural for Perl than for C), but in one go, and parse
everything later, so we might just as well do it in synchrony.

In the previous steps, we re-implemented the main loop of `git add -i`
in C, and most of the commands.
Notably, we left out the actual functionality of `patch`, as the
relevant code makes up more than half of `git-add--interactive.perl`,
and is actually pretty independent of the rest of the commands.
With this commit, we start to tackle that `patch` part. For better
separation of concerns, we keep the code in a separate file,
`add-patch.c`. The new code is still guarded behind the
`add.interactive.useBuiltin` config setting, and for the moment,
it can only be called via `git add -p`.
The actual functionality follows the original implementation of
5cde71d64aff (git-add --interactive, 2006-12-10), but not too closely
(for example, we use string offsets rather than copying strings around,
and after seeing whether the `k` and `j` commands are applicable, in the
C version we remember which previous/next hunk was undecided, and use it
rather than looking again when the user asked to jump).
As a further deviation from that commit, We also use a comma instead of
a slash to separate the available commands in the prompt, as the current
version of the Perl script does this, and we also add a line about the
question mark ("print help") to the help text.
While it is tempting to use this conversion of `git add -p` as an excuse
to work on `apply_all_patches()` so that it does _not_ want to read a
file from `stdin` or from a file, but accepts, say, an `strbuf` instead,
we will refrain from this particular rabbit hole at this stage.
