2021-02-10tests: remove most uses of test_i18ncmpLibravatar Ævar Arnfjörð Bjarmason1-1/+1
As a follow-up to d162b25f956 (tests: remove support for GIT_TEST_GETTEXT_POISON, 2021-01-20) remove most uses of test_i18ncmp via a simple s/test_i18ncmp/test_cmp/g search-replacement. I'm leaving t6300-for-each-ref.sh out due to a conflict with in-flight changes between "master" and "seen", as well as the prerequisite itself due to other changes between "master" and "next/seen" which add new test_i18ncmp uses.

"git diff" showed a submodule working tree with untracked cruft as "Submodule commit <objectname>-dirty", but a natural expectation is that the "-dirty" indicator would align with "git describe --dirty", which does not consider having untracked files in the working tree as source of dirtiness. The inconsistency has been fixed. * sj/untracked-files-in-submodule-directory-is-not-dirty: diff: do not show submodule with untracked files as "-dirty"
2020-12-08diff: do not show submodule with untracked files as "-dirty"Libravatar Sangeeta Jain1-0/+6
Git diff reports a submodule directory as -dirty even when there are only untracked files in the submodule directory. This is inconsistent with what `git describe --dirty` says when run in the submodule directory in that state. Make `--ignore-submodules=untracked` the default for `git diff` when there is no configuration variable or command line option, so that the command would not give '-dirty' suffix to a submodule whose working tree has untracked files, to make it consistent with `git describe --dirty` that is run in the submodule working tree. And also make `--ignore-submodules=none` the default for `git status` so that the user doesn't end up deleting a submodule that has uncommitted (untracked) files.

2020-11-19tests: mark tests relying on the current default for `init.defaultBranch`Libravatar Johannes Schindelin1-0/+3
In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch.

2020-11-16add -i: verify in the tests that colors can be overriddenLibravatar Johannes Schindelin1-0/+84
Now that the Perl version produces the same output as the built-in version (mostly fixing bugs in the latter), let's add a regression test to verify that it stays this way. Note that we only `grep` for the colored error message instead of verifying that the entire `stderr` consists of just this one line: when running the test script using the `-x` option to trace the commands, the sub-shell in `force_color` causes those commands to be traced into `err.raw` (unless running in Bash where we set the `BASH_XTRACEFD` variable to avoid that). Also note that the color reset in the `<BLUE>+<RESET><BLUE>new<RESET>` line might look funny and unnecessary, as the corresponding `old` line does not reset the color after the diff marker only to turn the color back on right away. However, this is a (necessary) side effect of the white-space check: in `emit_line_ws_markup()`, we first emit the diff marker via `emit_line_0()` and then the rest of the line via `ws_check_emit()`. To leave them somewhat decoupled, the color has to be reset after the diff marker to allow for the rest of the line to start with another color (or inverted, in case of white-space issues). Finally, we have to simulate hunk editing: the `git add -p` command cannot rely on the internal diff machinery for coloring after letting the user edit a hunk; It has to "re-color" the edited hunk. This is the primary reason why that command is interested in the exact values of the `color.diff.*` settings in the first place. To test this re-coloring, we therefore have to pretend to edit a hunk and then show that hunk in the regression test.

2020-09-09add -p: fix editing of intent-to-add pathsLibravatar Phillip Wood1-0/+38
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) Signed-off-by: Phillip Wood <phillip.wood@dunelm.org.uk> Reported-by: Thomas Sullivan <tom@msbit.com.au> Reported-by: Yuchen Ying <ych@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-09-08add--interactive.perl: specify --no-color explicitlyLibravatar Jeff King1-0/+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.

2020-09-08add-patch: fix inverted return code of repo_read_index()Libravatar Jeff King1-0/+7
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.

2020-05-27checkout -p: handle new files correctlyLibravatar Johannes Schindelin1-0/+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`.

2020-01-31diff: move diff.wsErrorHighlight to "basic" configLibravatar Jeff King1-0/+13
We parse diff.wsErrorHighlight in git_diff_ui_config(), meaning that it doesn't take effect for plumbing commands, only for porcelains like git-diff itself. This is mildly annoying as it means scripts like add--interactive, which produce a user-visible diff with color, don't respect the option. We could teach that script to parse the config and pass it along as --ws-error-highlight to the diff plumbing. But there's a simpler solution. It should be reasonably safe for plumbing to respect this option, as it only kicks in when color is otherwise enabled. And anybody parsing colorized output must already deal with the fact that color.diff.* may change the exact output they see; those options have been part of git_diff_basic_config() since its inception in 9a1805a872 (add a "basic" diff config callback, 2008-01-04). So we can just move it to the "basic" config, which fixes add--interactive, along with any other script in the same boat, with a very low risk of hurting any plumbing users.

2020-01-15t3701: adjust difffilter testLibravatar Johannes Schindelin1-1/+1
In 42f7d45428e (add--interactive: detect bogus diffFilter output, 2018-03-03), we added a test case that verifies that the diffFilter feature complains appropriately when the output is too short. In preparation for the upcoming change where the built-in `add -p` is taught to respect that setting, let's adjust that test a little. The problem is that `echo too-short` is configured as diffFilter, and it does not read the `stdin`. When calling it through `pipe_command()`, it is therefore possible that we try to feed the `diff` to it while it is no longer listening, and we receive a `SIGPIPE`. The Perl code apparently handles this in a way similar to an end-of-file, but taking a step back, we realize that a diffFilter that does not even _look_ at its standard input is very unrealistic. The entire point of this feature is to transform the diff, not to ignore it altogether. So let's modify the test case to reflect that insight: instead of printing some bogus text, let's use a diffFilter that deletes the first line of the diff instead. This still tests for the same thing, but it does not confuse the built-in `add -p` with that `SIGPIPE`.

2019-12-13built-in add -p: implement the hunk splitting featureLibravatar Johannes Schindelin1-0/+12
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.

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.

For the mode change prompt, we use a trick that lets this test case pass even on systems without executable bit, i.e. where `core.filemode = false` (such as Windows): we first add the file to the index with `git add --chmod=+x`, and then call `git add -p` with `core.filemode` forced to `true`. The file on disk has no executable bit set, therefore we will see a mode change. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-12-06t3701: avoid depending on the TTY prerequisiteLibravatar Johannes Schindelin1-7/+21
The TTY prerequisite is a rather heavy one: it not only requires Perl to work, but also the IO/Pty.pm module (with native support, and it requires pseudo terminals, too). In particular, test cases marked with the TTY prerequisite would be skipped in Git for Windows' SDK. In the case of `git add -p`, we do not actually need that big a hammer, as we do not want to test any functionality that requires a pseudo terminal; all we want is for the interactive add command to use color, even when being called from within the test suite. And we found exactly such a trick earlier already: when we added a test case to verify that the main loop of `git add -i` is colored appropriately. Let's use that trick instead of the TTY prerequisite. While at it, we avoid the pipes, as we do not want a SIGPIPE to break the regression test cases (which will be much more likely when we do not run everything through Perl because that is inherently slower).

2019-12-06t3701: add a test for advanced split-hunk editingLibravatar Johannes Schindelin1-0/+22
In this developer's workflows, it often happens that a hunk needs to be edited in a way that adds lines, and sometimes even reduces the number of context lines. Let's add a regression test for this. Note that just like the preceding test case, the new test case is *not* handled gracefully by the current `git add -p`. It will be handled correctly by the upcoming built-in `git add -p`, though.

2019-06-13add -p: fix checkout -p with pathological contextLibravatar Phillip Wood1-0/+8
Commit fecc6f3a68 ("add -p: adjust offsets of subsequent hunks when one is skipped", 2018-03-01) fixed adding hunks in the correct place when a previous hunk has been skipped. 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).

2018-09-11t3701-add-interactive: tighten the check of trace outputLibravatar SZEDER Gábor1-1/+1
The test 'add -p does not expand argument lists' in 't3701-add-interactive.sh', added in 7288e12cce (add--interactive: do not expand pathspecs with ls-files, 2017-03-14), checks the GIT_TRACE of 'git add -p' to ensure that the name of a tracked file wasn't passed around as argument to any of the commands executed as a result of undesired pathspec expansion. This check is done with 'grep' using the filename on its own as the pattern, which is too loose a pattern, and would match any occurrences of the filename in the trace output, not just those as command arguments. E.g. if a developer were to litter the index handling code with trace_printf()s printing, among other things, the name of the just processed cache entry, then that pattern would mistakenly match these as well, and would fail the test. Tighten this 'grep' pattern to only match trace lines that show the executed commands. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When user edits the patch in "git add -p" and the user's editor is set to strip trailing whitespaces indiscriminately, an empty line that is unchanged in the patch would become completely empty (instead of a line with a sole SP on it). The code introduced in Git 2.17 timeframe failed to parse such a patch, but now it learned to notice the situation and cope with it. * pw/add-p-recount: add -p: fix counting empty context lines in edited patches
2018-06-11add -p: fix counting empty context lines in edited patchesLibravatar Phillip Wood1-0/+43
recount_edited_hunk() introduced in commit 2b8ea7f3c7 ("add -p: calculate offset delta for edited patches", 2018-03-05) required all context lines to start with a space, empty lines are not counted. 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.

It's important that the diff-filter only filter the individual lines, and that there remain a one-to-one mapping between the input and output lines. Otherwise, things like hunk-splitting will behave quite unexpectedly (e.g., you think you are splitting at one point, but it has a different effect in the text patch we apply). We can't detect all problematic cases, but we can at least catch the obvious case where we don't even have the correct number of lines.

2018-03-05add -p: calculate offset delta for edited patchesLibravatar Phillip Wood1-1/+1
Recount the number of preimage and postimage lines in a hunk after it has been edited so any change in the number of insertions or deletions can be used to adjust the offsets of subsequent hunks. If an edited hunk is subsequently split then the offset correction will be lost. It would be possible to fix this if it is a problem, however the code here is still an improvement on the status quo for the common case where an edited hunk is applied without being split. This is also a necessary step to removing '--recount' and '--allow-overlap' from the invocation of 'git apply'. 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.

2018-03-01add -p: adjust offsets of subsequent hunks when one is skippedLibravatar Phillip Wood1-1/+1
Since commit 8cbd431082 ("git-add--interactive: replace hunk recounting with apply --recount", 2008-7-2) if a hunk is skipped then we rely on the context lines to apply subsequent hunks in the right place. While this works most of the time it is possible for hunks to end up being applied in the wrong place. To fix this adjust the offset of subsequent hunks to correct for any change in the number of insertions or deletions due to the skipped hunk. The change in offset due to edited hunks that have the number of insertions or deletions changed is ignored here, it will be fixed in the next commit.

When a hunk is skipped by add -i the offsets of subsequent hunks are not adjusted to account for any missing insertions due to the skipped hunk. Most of the time this does not matter as apply uses the context lines to apply the subsequent hunks in the correct place, however in pathological cases the context lines will match at the now incorrect offset and the hunk will be applied in the wrong place. The offsets of hunks following an edited hunk that has had the number of insertions or deletions changed also need to be updated in the same way. Add failing tests to demonstrate this.

Use a filter when comparing diffs to fix the value of non-zero hashes in diff index lines so we're not hard coding sha1 hash values in the expected output. This makes it easier to change the expected output if a test is edited as we don't need to worry about the exact hash value and means the tests will work when the hash algorithm is transitioned away from sha1.
