* add -p: avoid use of undefined $key when ReadKey -> EOFCarlo Marcelo Arenas Belón2021-11-281-7/+9
| | | | | | | | | | | | | | | | | | | | b5cc003253 (add -i: ignore terminal escape sequences, 2011-05-17) add an additional check to the original code to better handle keys for escape sequences, but failed to account for the possibility the first ReadKey call returned undef (ex: stdin closes) and that was being handled fine by the original code in ca6ac7f135 (add -p: prompt for single characters, 2009-02-05) Add a test for undefined and encapsulate the loop and the original print that relied on it within it.

| * add -p: prefer color.diff.context over color.diff.plainJohannes Schindelin2020-11-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Git's diff machinery allows users to override the colors to use in diffs, even the plain-colored context lines. As of 8dbf3eb6850 (diff.h: rename DIFF_PLAIN color slot to DIFF_CONTEXT, 2015-05-27), the preferred name of the config setting is `color.diff.context`, although Git still allows `color.diff.plain`. In the context of `git add -p`, this logic is a bit hard to replicate: `git_diff_basic_config()` reads all config values sequentially and if it sees _any_ `color.diff.context` or `color.diff.plain`, it accepts the new color. The Perl version of `git add -p` needs to go through `git config --get-color`, though, which allows only one key to be specified. The same goes for the built-in version of `git add -p`, which has to go through `repo_config_get_value()`. The best we can do here is to look for `.context` and if none is found, fall back to looking for `.plain`, and if still not found, fall back to the hard-coded default (which in this case is simply the empty string, as context lines are typically rendered without colored). This still leads to inconsistencies when both config names are used: the initial diff will be colored by the diff machinery. Once edited by a user, a hunk has to be re-colored by `git add -p`, though, which would then use the other setting to color the context lines. In practice, this is not _all_ that bad. The `git config` manual says this in the `color.diff.<slot>`: `context` (context text - `plain` is a historical synonym) We should therefore assume that users use either one or the other, but not both names. Besides, it is relatively uncommon to look at a hunk after editing it because it is immediately staged by default.

| | | | | | | | | | | | | | | | | | | | | | Both versions of `add -i` indent non-flat lists by five spaces. However when using color the C version prints these spaces after the ANSI color codes whereas the Perl version prints them before the color codes.

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.

* | add--interactive.perl: specify --no-color explicitlyJeff King2020-09-081-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our color tests of "git add -p" do something a bit different from how a normal user would behave: we pretend there's a pager in use, so that Git thinks it's OK to write color to a non-tty stdout. This comes from 8539b46534 (t3701: avoid depending on the TTY prerequisite, 2019-12-06), which allows us to avoid a lot of complicated mock-tty code. However, those environment variables also make their way down to sub-processes of add--interactive, including the "diff-files" we run to generate the patches. As a result, it thinks it should output color, too. So in t3701.50, for example, the machine-readable version of the diff we get unexpectedly has color in it. We fail to parse it as a diff and think there are zero hunks. The test does still pass, though, because even with zero hunks we'll dump the diff header (and we consider those unparseable bits to be part of the header!), and so the output still has the expected color codes in it. We don't notice that the command was totally broken and failed to apply anything. And in fact we're not really testing what we think we are about the color, either. While add--interactive does correctly show the version we got from running "diff-files --color", we'd also pass the test if we had accidentally shown the machine-readable version, too, since it (erroneously) has color codes in it. One could argue that the test isn't very realistic; it's setting up this "pretend there's a pager" situation to get around the tty restrictions of the test environment. So one option would be to move back towards using a real tty. But the behavior of add--interactive really is user-visible here. If a user, for whatever reason, did run "git --paginate add --patch" (perhaps because their pager is really a filter or something), the command would totally fail to do anything useful. Since we know that we don't want color in this output, let's just make add--interactive more defensive, and say "--no-color" explicitly. It doesn't hurt anything in the common case, but it fixes this odd case and lets our test function properly again. Note that the C builtin run_add_p() already passes --no-color, so it doesn't need a similar fix. That will eventually replace this perl code anyway, but the test change here will be valuable for ensuring that.

* checkout -p: handle new files correctlyJohannes Schindelin2020-05-271-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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`.

* git add -p: use non-zero exit code when the diff generation failedJohannes Schindelin2019-12-061-3/+5
| | | | | | | | | | | | | | | | | | | | | The first thing `git add -p` does is to generate a diff. If this diff cannot be generated, `git add -p` should not continue as if nothing happened, but instead fail. What we *actually* do here is much broader: we now verify for *every* `run_cmd_pipe()` call that the spawned process actually succeeded. Note that we have to change two callers in this patch, as we need to store the spawned process' output in a local variable, which means that the callers can no longer decide whether to interpret the `return <$fh>` in array or in scalar context. This bug was noticed while writing a test case for the diff.algorithm feature, and we let that test case double as a regression test for this fixed bug, too.

However it did not address patches that are applied in reverse. In that case we need to adjust the pre-image offset so that when apply reverses the patch the post-image offset is adjusted correctly. We subtract rather than add the delta as the patch is reversed (the easiest way to think about it is to consider a hunk of deletions that is skipped - in that case we want to reduce offset so we need to subtract).

This was intended to avoid any recounting problems if the user had introduced empty lines at the end when editing the patch. However this introduced a regression into 'git add -p' as it seems it is common for editors to strip the trailing whitespace from empty context lines when patches are edited thereby introducing empty lines that should be counted. 'git apply' knows how to deal with such empty lines and POSIX states that whether or not there is an space on an empty context line is implementation defined [1]. Fix the regression by counting lines that consist solely of a newline as well as lines starting with a space as context lines and add a test to prevent future regressions.

Before '--recount' can be removed the splitting and coalescing counting needs to be fixed to handle a missing newline at the end of a file. In order to remove '--allow-overlap' there needs to be i) some way of verifying the offset data in the edited hunk (probably by correlating the preimage (or postimage if the patch is going to be applied in reverse) lines of the edited and unedited versions to see if they are offset or if any leading/trailing context lines have been removed) and ii) a way of dealing with edited hunks that change context lines that are shared with neighbouring hunks.

|/ | | | | | | | | | | | | | | | For 'add -i' and 'add -p', the only action we can take on a dirty submodule entry is update the index with a new value from its HEAD. The content changes inside (from its own index, untracked files...) do not matter, at least until 'git add -i' learns about launching a new interactive add session inside a submodule. Ignore all other submodules changes except HEAD. This reduces the number of entries the user has to check through in 'git add -i', and the number of 'no' they have to answer to 'git add -p' when dirty submodules are present.

We can fix that by telling perl not to respect metacharacters.

Without modifying the callers that effectively turns it into a "no" response. This is reasonable for both of the current callers, and it leaves room for any future caller to check for undef explicitly.

If your pathspec expands into a large number of paths, you may run into one of two problems: 1. The OS may complain about the size of the argument list, and refuse to run. For example: $ (ulimit -s 128 && git add -p drivers) Can't exec "git": Argument list too long at .../git-add--interactive line 177. Died at .../git-add--interactive line 177. That's on the linux.git repository, which has about 20K files in the "drivers" directory (none of them modified in this case). The "ulimit -s" trick is necessary to show the problem on Linux even for such a gigantic set of paths. Other operating systems have much smaller limits (e.g., a real-world case was seen with only 5K files on OS X). 2. Even when it does work, it's really slow. The pathspec code is not optimized for huge numbers of paths. Here's the same case without the ulimit: $ time git add -p drivers No changes. real 0m16.559s user 0m53.140s sys 0m0.220s We can improve this by skipping "ls-files" completely, and just feeding the original pathspecs to the diff commands. This solution was discussed in 2010: http://public-inbox.org/git/20100105041438.GB12574@coredump.intra.peff.net/ but at the time the diff code's pathspecs were more primitive than those used by ls-files (e.g., they did not support globs). Making the change would have caused a user-visible regression, so we didn't. Since then, the pathspec code has been unified, and the diff commands natively understand pathspecs like '*.c'. This patch implements that solution. That skips the argument-list limits, and the result runs much faster: $ time git add -p drivers No changes. real 0m0.149s user 0m0.116s sys 0m0.080s There are two new tests. The first just exercises the globbing behavior to confirm that we are not causing a regression there. The second checks the actual argument behavior using GIT_TRACE. We _could_ do it with the "ulimit -s" trick, as above. But that would mean the test could only run where "ulimit -s" works. And tests of that sort are expensive, because we have to come up with enough files to actually bust the limit (we can't just shrink the "128" down infinitely, since it is also the in-program stack size). Finally, two caveats and possibilities for future work: a. This fixes one argument-list expansion, but there may be others. In fact, it's very likely that if you run "git add -i" and select a large number of modified files that the script would try to feed them all to a single git command. In practice this is probably fine. The real issue here is that the argument list was growing with the _total_ number of files, not the number of modified or selected files. b. If the repository contains filenames with literal wildcard characters (e.g., "foo*"), the original code expanded them via "ls-files" and then fed those wildcard names to "diff-index", which would have treated them as wildcards. This was a bug, which is now fixed (though unless you really go through some contortions with ":(literal)", it's likely that your original pathspec would match whatever the accidentally-expanded wildcard would anyway). So this takes us one step closer to working correctly with files whose names contain wildcard characters, but it's likely that others remain (e.g., if "git add -i" feeds the selected paths to "git add").

This includes the "patch" option, which gets the list before starting the hunk-selection loop. As "git add -p", it behaves differently, and jumps straight to the hunk selection loop. Since 0539d5e6d (i18n: add--interactive: mark patch prompt for translation, 2016-12-14), the "add -i" case mistakenly jumps to straight to the hunk-selection loop. Prior to that commit the distinction between the two cases was managed by the $patch_mode variable. That commit used $patch_mode for something else, and moved the old meaning to the "$cmd" variable. But it forgot to update the $patch_mode check inside patch_update_cmd() which controls the file-list behavior. The simplest fix would be to change that line to check $cmd. But while we're here, let's use a less obscure name for this flag: $patch_mode_only, a boolean which tells whether we are in full-interactive mode or only in patch-mode.

We have been trying to improve the choice of this boundary, and Git 2.11 shipped with an experimental "compaction-heuristic". Since then another attempt to improve the logic further resulted in a new "indent-heuristic" logic. It is agreed that the latter gives better result overall, and the former outlived its usefulness. Retire "compaction", and keep "indent" as an experimental feature. The latter hopefully will be turned on by default in a future release, but that should be done as a separate step.
