Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

Regression fix for 2.34
* ds/add-rm-with-sparse-index:
dir: revert "dir: select directories correctly"
|
|
This reverts commit f6526728f950cacfd5b5e42bcc65f2c47f3da654.
The change in f652672 (dir: select directories correctly, 2021-09-24)
caused a regression in directory-based matches with non-cone-mode
patterns, especially for .gitignore patterns. A test is included to
prevent this regression in the future.
The commit ed495847 (dir: fix pattern matching on dirs, 2021-09-24) was
reverted in 5ceb663 (dir: fix directory-matching bug, 2021-11-02) for
similar reasons. Neither commit changed tests, and tests added later in
the series continue to pass when these commits are reverted.

Regression fix.
* ds/add-rm-with-sparse-index:
dir: fix directory-matching bug
|
|
This reverts the change from ed49584 (dir: fix pattern matching on dirs,
2021-09-24), which claimed to fix a directory-matching problem without a
test case. It turns out to _create_ a bug, but it is a bit subtle.
The bug would have been revealed by the first of two tests being added to
t0008-ignores.sh. The first uses a pattern "/git/" inside the a/.gitignores
file, which matches against 'a/git/foo' but not 'a/git-foo/bar'. This test
would fail before the revert.
The second test shows what happens if the test instead uses a pattern "git/"
and this test passes both before and after the revert.
The difference in these two cases are due to how
last_matching_pattern_from_list() checks patterns both if they have the
PATTERN_FLAG_MUSTBEDIR and PATTERN_FLAG_NODIR flags. In the case of "git/",
the PATTERN_FLAG_NODIR is also provided, making the change in behavior in
match_pathname() not affect the end result of
last_matching_pattern_from_list().

It does not make sense to make ".gitattributes", ".gitignore" and
".mailmap" symlinks, as they are supposed to be usable from the
object store (think: bare repositories where HEAD:.mailmap etc. are
used). When these files are symbolic links, we used to read the
contents of the files pointed by them by mistake, which has been
corrected.
* jk/open-dotgitx-with-nofollow:
mailmap: do not respect symlinks for in-tree .mailmap
exclude: do not respect symlinks for in-tree .gitignore
attr: do not respect symlinks for in-tree .gitattributes
exclude: add flags parameter to add_patterns()
attr: convert "macro_ok" into a flags field
add open_nofollow() helper
|
|
As with .gitattributes, we would like to make sure that .gitignore files
are handled consistently whether read from the index or from the
filesystem. Likewise, we would like to avoid reading out-of-tree files
pointed to by the symlinks, which could have security implications in
certain setups.
We can cover both by using open_nofollow() when opening the in-tree
files. We'll continue to follow links for core.excludesFile, as well as
$GIT_DIR/info/exclude.

check-ignore has two different modes, and neither of these modes has an
implementation that matches the documentation. These modes differ in
whether they just print paths or whether they also print the final
pattern matched by the path. The fix is different for both modes, so
I'll discuss both separately.
=== First (default) mode ===
The first mode is documented as:
For each pathname given via the command-line or from a file via
--stdin, check whether the file is excluded by .gitignore (or other
input files to the exclude mechanism) and output the path if it is
excluded.
However, it fails to do this because it did not account for negated
patterns. Commands other than check-ignore verify exclusion rules via
calling
... -> treat_one_path() -> is_excluded() -> last_matching_pattern()
while check-ignore has a call path of the form:
... -> check_ignore() -> last_matching_pattern()
The fact that the latter does not include the call to is_excluded()
means that it is susceptible to to messing up negated patterns (since
that is the only significant thing is_excluded() adds over
last_matching_pattern()). Unfortunately, we can't make it just call
is_excluded(), because the same codepath is used by the verbose mode
which needs to know the matched pattern in question. This brings us
to...
=== Second (verbose) mode ===
The second mode, known as verbose mode, references the first in the
documentation and says:
Also output details about the matching pattern (if any) for each
given pathname. For precedence rules within and between exclude
sources, see gitignore(5).
The "Also" means it will print patterns that match the exclude rules as
noted for the first mode, and also print which pattern matches. Unless
more information is printed than just pathname and pattern (which is not
done), this definition is somewhat ill-defined and perhaps even
self-contradictory for negated patterns: A path which matches a negated
exclude pattern is NOT excluded and thus shouldn't be printed by the
former logic, while it certainly does match one of the explicit patterns
and thus should be printed by the latter logic.
=== Resolution ==
Since the second mode exists to find out which pattern matches given
paths, and showing the user a pattern that begins with a '!' is
sufficient for them to figure out whether the pattern is excluded, the
existing behavior is desirable -- we just need to update the
documentation to match the implementation (i.e. it is about printing
which pattern is matched by paths, not about showing which paths are
excluded).
For the first or default mode, users just want to know whether a pattern
is excluded. As such, the existing documentation is desirable; change
the implementation to match the documented behavior.
Finally, also adjust a few tests in t0008 that were caught up by this
discrepancy in how negated paths were handled.

The test functions test_i18ncmp and test_i18ngrep pretend success if run
under GETTEXT_POISON. By using those functions to test output which is
correctly marked as translatable, enables one to detect if the strings
newly marked for translation are from plumbing output. If they are
indeed from plumbing, the test would fail, and the string should be
unmarked, since it is not seen by users.
Thus, it is productive to not have false positives when running the test
under GETTEXT_POISON. This commit replaces normal test functions by
their i18n aware variants in use-cases know to be correctly marked for
translation, suppressing false positives.

In t0008, we have
cat <<-EOF
...
a/b/.gitignore:8:!on* "a/b/one\"three"
...
EOF
and expect that the backslash-dq is passed through literally.
ksh88 eats the backslash and produces a wrong expect file to
compare the actual output with.
Using \\" works this around without breaking other POSIX shells
(which collapse backslash-backslash to a single backslash), and
ksh88 does so, too.
It makes it easier to read, too, because the reason why we are
writing backslash there is *not* because we think dq is special and
want to quote it (if that were the case we would have two more
backslashes on that line). It is simply because we want a single
literal backslash there. Since backslash is treated specially in
unquoted here-document, explicitly doubling it to quote it expresses
our intent better than relying on the character that immediately
comes after it (i.e. '"') not being a special character.

The colon is used by check-ignore to separate paths from other output
values. If we use an absolute path, however, on Windows it will be
converted into a Windows path that very much contains a colon.
It is actually not at all necessary to make the path of the global
excludes absolute, so let's just not even do that.

core.excludesfile (defaulting to $XDG_HOME/git/ignore) is supposed
to be overridden by repository-specific .git/info/exclude file, but
the order was swapped from the beginning. This belatedly fixes it.
* jc/gitignore-precedence:
ignore: info/exclude should trump core.excludesfile
|
|
$GIT_DIR/info/exclude and core.excludesfile (which falls back to
$XDG_HOME/git/ignore) are both ways to override the ignore pattern
lists given by the project in .gitignore files. The former, which
is per-repository personal preference, should take precedence over
the latter, which is a personal preference default across different
repositories that are accessed from that machine. The existing
documentation also agrees.
However, the precedence order was screwed up between these two from
the very beginning when 896bdfa2 (add: Support specifying an
excludes file with a configuration variable, 2007-02-27) introduced
core.excludesfile variable.

Discard the unnecessary 'nr_spaces' variable, remove 'strlen()' and
improve the 'if' structure. Switch to pointers instead of integers
to control the loop.
Slightly more rare occurrences of 'text \ ' with a backslash
in between spaces are handled correctly. Namely, the code in
7e2e4b37 (dir: ignore trailing spaces in exclude patterns, 2014-02-09)
does not reset 'last_space' when a backslash is encountered and the above
line stays intact as a result.

The Windows API does not preserve file names with trailing spaces (and
dots), but rather strips them. Our tools (MSYS bash, git) base the POSIX
emulation on the Windows API. As a consequence, it is impossible for bash
on Windows to allocate a file whose name has trailing spaces, and for git
to stat such a file. Both operate on a file whose name has the spaces
stripped. Skip the test that needs such a file name.
Note that we do not use (another incarnation of) prerequisite FUNNYNAMES.
The reason is that FUNNYNAMES is intended to represent a property of the
file system. But the inability to have trailing spaces in a file name is
a property of the Windows API. The file system (NTFS) does not have this
limitation.

Solaris' tr (both /usr/bin/ and /usr/xpg4/bin) uses the System V
semantics for tr whereby string1's length is truncated to the length
of string2 if string2 is shorter. The BSD semantics, as used by GNU tr
see string2 padded to the length of string1 using the final character
in string2. POSIX explicitly doesn't specify the correct behavior
here, making both equally valid.
This difference means that Solaris' native tr implementations produce
different results for tr ":\t\n" "\0" than GNU tr. This breaks a few
tests in t0008-ignores.sh.
Possible fixes for this are to make string2 be "\0\0\0" or "[\0*]".
Instead, use perl to perform these transliterations which means we
don't need to worry about the difference at all. Since we're replacing
tr with perl, we also use perl to replace the sed invocations used to
transform the files.
Replace four identical transforms with a function named
broken_c_unquote. Replace the other two identical transforms with a
fuction named broken_c_unquote_verbose.

"git check-ignore" follows the same rule as "git add" and "git
status" in that the ignore/exclude mechanism does not take effect
on paths that are already tracked. With "--no-index" option, it
can be used to diagnose which paths that should have been ignored
have been mistakenly added to the index.
* dw/check-ignore-sans-index:
check-ignore: Add option to ignore index contents
|
|
check-ignore currently shows how .gitignore rules would treat untracked
paths. Tracked paths do not generate useful output. This prevents
debugging of why a path became tracked unexpectedly unless that path is
first removed from the index with `git rm --cached <path>`.
The option --no-index tells the command to bypass the check for the
path being in the index and hence allows tracked paths to be checked
too.
Whilst this behaviour deviates from the characteristics of `git add` and
`git status` its use case is unlikely to cause any user confusion.
Test scripts are augmented to check this option against the standard
ignores to ensure correct behaviour.

check-ignore (at least the test suite) seems to rely on the pattern
order. PATHSPEC_KEEP_ORDER is introduced to explictly express this.
The lack of PATHSPEC_MAXDEPTH_VALID is sufficient because it's the

To test check-ignore's --stdin feature, we use two fifos to
send and receive data. We carefully keep a descriptor to its
input open so that it does not receive EOF between input
lines. However, we do not do the same for its output. That
means there is a potential race condition in which
check-ignore has opened the output pipe once (when we read
the first line), and then writes the second line before we
have re-opened the pipe.
In that case, check-ignore gets a SIGPIPE and dies. The
outer shell then tries to open the output fifo but blocks
indefinitely, because there is no writer. We can fix it by
keeping a descriptor open through the whole procedure.
This should also help if check-ignore dies for any other
reason (we would already have opened the fifo and would
therefore not block, but just get EOF on read).
However, we are technically still susceptible to
check-ignore dying early, before we have opened the fifo.
This is an unlikely race and shouldn't generally happen in
practice, though, so we can hopefully ignore it.

sleeps in the check-ignore test suite are not ideal since they can
fail when the system is under load, or when a tool like valgrind is
used which drastically alters the timing. Therefore we replace them
with a more robust solution using a named pipe (FIFO).

Some callers, such as the git-annex web assistant, find it useful to
invoke git check-ignore as a persistent background process, which can
then have queries fed to its STDIN at any point, and the corresponding
response consumed from its STDOUT. For this we need to invoke
check_ignore() once per line of standard input, and flush standard
output after each result.
The above use case suggests that empty STDIN is actually a reasonable
scenario (e.g. when the caller doesn't know in advance whether any
queries need to be fed to the background process until after it's
already started), so we make the minor behavioural change that "no
pathspec given." is no longer emitted in when STDIN is empty.
Even though check_ignore() could now be changed to operate on a single
pathspec, we keep it operating on an array of pathspecs since that is
a more convenient way of consuming the existing pathspec API.

If `-n` or `--non-matching` are specified, non-matching pathnames will
also be output, in which case all fields in each output record except
for <pathname> will be empty. This can be useful when running
check-ignore as a background process, so that files can be
incrementally streamed to STDIN, and for each of these files, STDOUT
will indicate whether that file matched a pattern or not. (Without
this option, it would be impossible to tell whether the absence of
output for a given file meant that it didn't match any pattern, or
that the result simply hadn't been flushed to STDOUT yet.)

Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"
Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.
