2014-03-11t0008: skip trailing space test on WindowsLibravatar Johannes Sixt1-1/+1
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. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-10-30Avoid difference in tr semantics between System V and BSDLibravatar Ben Walton1-12/+18
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. Signed-off-by: Ben Walton <bdwalton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-09-20Merge branch 'dw/check-ignore-sans-index'Libravatar Junio C Hamano1-9/+63
"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
2013-09-12check-ignore: Add option to ignore index contentsLibravatar Dave Williams1-9/+63
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.

2013-07-15check-ignore: convert to use parse_pathspecLibravatar Nguyễn Thái Ngọc Duy1-4/+4
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 only flag that reorders pathspecs, but it's less obvious that way.

2013-07-12t0008: avoid SIGPIPE race condition on fifoLibravatar Jeff King1-2/+10
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. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-04-29t0008: use named pipe (FIFO) to test check-ignore streamingLibravatar Adam Spiers1-21/+17
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). Thanks to Jeff King for coming up with the redirection wizardry required to make this work. http://article.gmane.org/gmane.comp.version-control.git/220916 Signed-off-by: Adam Spiers <git@adamspiers.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-04-11check-ignore: allow incremental streaming of queries via --stdinLibravatar Adam Spiers1-5/+23
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.

2013-04-11check-ignore: add -n / --non-matching optionLibravatar Adam Spiers1-32/+90
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.)

2013-02-19name-hash: allow hashing an empty stringLibravatar Junio C Hamano1-0/+5
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.
