The sequencer infrastructure is shared across "git cherry-pick", "git rebase -i", etc., and has always spawned "git commit" when it needs to create a commit.

2018-01-30wildmatch test: mark test as EXPENSIVE_ON_WINDOWSLibravatar Ævar Arnfjörð Bjarmason1-8/+8
Mark the newly added test which creates test files on-disk as EXPENSIVE_ON_WINDOWS. According to [1] it takes almost ten minutes to run this test file on Windows after this recent change, but just a few seconds on Linux as noted in my [2]. This could be done faster by exiting earlier, however by using this pattern we'll emit "skip" lines for each skipped test, making it clear we're not running a lot of them in the TAP output, at the cost of some overhead. 1. nycvar.QRO.7.76.6.1801061337020.1337@wbunaarf-fpuvaqryva.tvgsbejvaqbjf.bet (https://public-inbox.org/git/nycvar.QRO.7.76.6.1801061337020.1337@wbunaarf-fpuvaqryva.tvgsbejvaqbjf.bet/) 2. 87mv1raz9p.fsf@evledraar.gmail.com (https://public-inbox.org/git/87mv1raz9p.fsf@evledraar.gmail.com/) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-01-30wildmatch test: create & test files on disk in addition to in-memoryLibravatar Ævar Arnfjörð Bjarmason1-11/+190
There has never been any full roundtrip testing of what git-ls-files and other commands that use wildmatch() actually do, rather we've been satisfied with just testing the underlying C function. Due to git-ls-files and friends having their own codepaths before they call wildmatch() there's sometimes differences in the behavior between the two. Even when we test for those (as with [1]), there was no one place where you can review how these two modes differ. Now there is. We now attempt to create a file called $haystack and match $needle against it for each pair of $needle and $haystack that we were passing to test-wildmatch. If we can't create the file we skip the test. This ensures that we can run this on all platforms and not maintain some infinitely growing whitelist of e.g. platforms that don't support certain characters in filenames. A notable exception to this is Windows, where due to the reasons explained in [2] the shellscript emulation layer might fake the creation of a file such as "*", and "test -e" for it will succeed since it just got created with some character that maps to "*", but git ls-files won't be fooled by this. Thus we need to skip creating certain filenames entirely on Windows, the list here might be overly aggressive. I don't have access to a Windows system to test this. As a result of doing these tests we can now see the cases where these two ways of testing wildmatch differ: * Creating a file called 'a[]b' and running ls-files 'a[]b' will show that file, but wildmatch("a[]b", "a[]b") will not match * wildmatch() won't match a file called \ against \, but ls-files will. * `git --glob-pathspecs ls-files 'foo**'` will match a file 'foo/bba/arr', but wildmatch won't, however pathmatch will. This seems like a bug to me, the two are otherwise equivalent as these tests show. This also reveals the case discussed in [1], since 2.16.0 '' is now an error as far as ls-files is concerned, but wildmatch() itself happily accepts it. 1. 9e4e8a64c2 ("pathspec: die on empty strings as pathspec", 2017-06-06) 2. nycvar.QRO.7.76.6.1801052133380.1337@wbunaarf-fpuvaqryva.tvgsbejvaqbjf.bet (https://public-inbox.org/git/?q=nycvar.QRO.7.76.6.1801052133380.1337%40wbunaarf-fpuvaqryva.tvgsbejvaqbjf.bet) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-01-30wildmatch test: perform all tests under all wildmatch() modesLibravatar Ævar Arnfjörð Bjarmason2-252/+228
Rewrite the wildmatch() test suite so that each test now tests all combinations of the wildmatch() WM_CASEFOLD and WM_PATHNAME flags. Before this change some test inputs were not tested on e.g. WM_PATHNAME. Now the function is stress tested on all possible inputs, and for each input we declare what the result should be if the mode is case-insensitive, or pathname matching, or case-sensitive or not matching pathnames. Also before this change, nothing was testing case-insensitive non-pathname matching, so I've added that to test-wildmatch.c and made use of it. This yields a rather scary patch, but there are no functional changes here, just more test coverage. Some now-redundant tests were deleted as a result of this change, since they were now duplicating an earlier test.

This is something I added in commit 77f6f4406f ("grep: add a test helper function for less verbose -f \0 tests", 2017-05-20) to grep tests, which were modeled on these wildmatch tests, and I'm now porting back to the original wildmatch tests. I am not using the "say '...'; exit 1" pattern from t0000-basic.sh because if I fail I want to run the rest of the tests (unless under -i), and doing this makes sure we do that and don't exit right away without fully reporting our errors.

2018-01-25daemon: fix length computation in newline strippingLibravatar Jeff King1-0/+15
When git-daemon gets a pktline request, we strip off any trailing newline, replacing it with a NUL. Clients prior to 5ad312bede (in git v1.4.0) would send: git-upload-pack repo.git\n and we need to strip it off to understand their request. After 5ad312bede, we send the host attribute but no newline, like: git-upload-pack repo.git\0host=example.com\0 Both of these are parsed correctly by git-daemon. But if some client were to combine the two: git-upload-pack repo.git\n\0host=example.com\0 we don't parse it correctly. The problem is that we use the "len" variable to record the position of the NUL separator, but then decrement it when we strip the newline. So we start with: git-upload-pack repo.git\n\0host=example.com\0 ^-- len and end up with: git-upload-pack repo.git\0\0host=example.com\0 ^-- len This is arguably correct, since "len" tells us the length of the initial string, but we don't actually use it for that. What we do use it for is finding the offset of the extended attributes; they used to be at len+1, but are now at len+2. We can solve that by just leaving "len" where it is. We don't have to care about the length of the shortened string, since we just treat it like a C string. No version of Git ever produced such a string, but it seems like the daemon code meant to handle this case (and it seems like a reasonable thing for somebody to do in a 3rd-party implementation).

2018-01-25t/lib-git-daemon: add network-protocol helpersLibravatar Jeff King2-1/+58
All of our git-protocol tests rely on invoking the client and having it make a request of a server. That gives a nice real-world test of how the two behave together, but it doesn't leave any room for testing how a server might react to _other_ clients. Let's add a few test helper functions which can be used to manually conduct a git-protocol conversation with a remote git-daemon: 1. To connect to a remote git-daemon, we need something like "netcat". But not everybody will have netcat. And even if they do, the behavior with respect to half-duplex shutdowns is not portable (openbsd netcat has "-N", with others you must rely on "-q 1", which is racy). Here we provide a "fake_nc" that is capable of doing a client-side netcat, with sane half-duplex semantics. It relies on perl's IO::Socket::INET. That's been in the base distribution since 5.6.0, so it's probably available everywhere. But just to be on the safe side, we'll add a prereq. 2. To help tests speak and read pktline, this patch adds packetize() and depacketize() functions. I've put fake_nc() into lib-git-daemon.sh, since that's really the only server where we'd need to use a network socket. Whereas the pktline helpers may be of more general use, so I've added them to test-lib-functions.sh. Programs like upload-pack speak pktline, but can talk directly over stdio without a network socket. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-01-25daemon: handle NULs in extended attribute stringLibravatar Jeff King1-3/+5
If we receive a request with extended attributes after the NUL, we try to write those attributes to the log. We do so with a "%s" format specifier, which will only show characters up to the first NUL. That's enough for printing a "host=" specifier. But since dfe422d04d (daemon: recognize hidden request arguments, 2017-10-16) we may have another NUL, followed by protocol parameters, and those are not logged at all. Let's cut out the attempt to show the whole string, and instead log when we parse individual attributes. We could leave the "extended attributes (%d bytes) exist" part of the log, which in theory could alert us to attributes that fail to parse. But anything we don't parse as a "host=" parameter gets blindly added to the "protocol" attribute, so we'd see it in that part of the log.

2018-01-25daemon: fix off-by-one in logging extended attributesLibravatar Jeff King1-0/+11
If receive a request like: git-upload-pack /foo.git\0host=localhost we mark the offset of the NUL byte as "len", and then log the bytes after the NUL with a "%.*s" placeholder, using "pktlen - len" as the length, and "line + len + 1" as the start of the string. This is off-by-one, since the start of the string skips past the separating NUL byte, but the adjusted length includes it. Fortunately this doesn't actually read past the end of the buffer, since "%.*s" will stop when it hits a NUL. And regardless of what is in the buffer, packet_read() will always add an extra NUL terminator for safety. As an aside, the git.git client sends an extra NUL after a "host" field, too, so we'd generally hit that one first, not the one added by packet_read(). You can see this in the test output which reports 15 bytes, even though the string has only 14 bytes of visible data. But the point is that even a client sending unusual data could not get us to read past the end of the buffer, so this is purely a cosmetic fix.

2018-01-25t/lib-git-daemon: record daemon logLibravatar Jeff King1-4/+12
When we start git-daemon for our tests, we send its stderr log stream to a named pipe. We synchronously read the first line to make sure that the daemon started, and then dump the rest to descriptor 4. This is handy for debugging test output with "--verbose", but the tests themselves can't access the log data. Let's dump the log into a file, as well, so that future tests can check the log. There are a few subtleties worth calling out here: - we'll continue to send output to descriptor 4 for viewing/debugging, which would imply swapping out "cat" for "tee". But we want to ensure that there's no buffering, and "tee" doesn't have a standard way to ask for that. So we'll use a shell loop around "read" and "printf" instead. That ensures that after a request has been served, the matching log entries will have made it to the file. - the existing first-line shell loop used read/echo. We'll switch to consistently using "read -r" and "printf" to relay data as faithfully as possible. - we open the logfile for append, rather than just output. That makes it OK for tests to truncate the logfile without restarting the daemon (the OS will atomically seek to the end of the file when outputting each line). That allows tests to look at the log without worrying about pollution from earlier tests.

2018-01-24t7505: add tests for cherry-pick and rebase -i/-pLibravatar Phillip Wood3-4/+157
Check that cherry-pick and rebase call the 'prepare-commit-msg' hook correctly. The expected values for the hook arguments are taken to match the current master branch. I think there is scope for improving the arguments passed so they make a bit more sense - for instance cherry-pick currently passes different arguments depending on whether the commit message is being edited. Also the arguments for rebase could be improved. Commit 7c4188360ac ("rebase -i: proper prepare-commit-msg hook argument when squashing", 2008-10-3) apparently changed things so that when squashing rebase would pass 'squash' as the argument to the hook but that has been lost. I think that it would make more sense to pass 'message' for revert and cherry-pick -x/-s (i.e. cases where there is a new message or the current message in modified by the command), 'squash' when squashing with a new message and 'commit HEAD/CHERRY_PICK_HEAD' otherwise (picking and squashing without a new message).

2018-01-24read-cache: don't write index twice if we can't write shared indexLibravatar Nguyễn Thái Ngọc Duy1-0/+19
In a0a967568e ("update-index --split-index: do not split if $GIT_DIR is read only", 2014-06-13), we tried to make sure we can still write an index, even if the shared index can not be written. We did so by just calling 'do_write_locked_index()' just before 'write_shared_index()'. 'do_write_locked_index()' always at least closes the tempfile nowadays, and used to close or commit the lockfile if COMMIT_LOCK or CLOSE_LOCK were given at the time this feature was introduced. COMMIT_LOCK or CLOSE_LOCK is passed in by most callers of 'write_locked_index()'. After calling 'write_shared_index()', we call 'write_split_index()', which calls 'do_write_locked_index()' again, which then tries to use the closed lockfile again, but in fact fails to do so as it's already closed. This eventually leads to a segfault. Make sure to write the main index only once.

2018-01-23Merge branch 'nd/add-i-ignore-submodules'Libravatar Junio C Hamano1-0/+48
"git add -p" was taught to ignore local changes to submodules as they do not interfere with the partial addition of regular changes anyway. * nd/add-i-ignore-submodules: add--interactive: ignore submodule changes except HEAD
2018-01-23Merge branch 'mm/send-email-fallback-to-local-mail-address'Libravatar Junio C Hamano3-94/+19
Instead of maintaining home-grown email address parsing code, ship a copy of reasonably recent Mail::Address to be used as a fallback in 'git send-email' when the platform lacks it. * mm/send-email-fallback-to-local-mail-address: send-email: add test for Linux's get_maintainer.pl perl/Git: remove now useless email-address parsing code send-email: add and use a local copy of Mail::Address
2018-01-23Merge branch 'tg/stash-with-pathspec-fix'Libravatar Junio C Hamano1-0/+32
"git stash -- <pathspec>" incorrectly blew away untracked files in the directory that matched the pathspec, which has been corrected. * tg/stash-with-pathspec-fix: stash: don't delete untracked files that match pathspec
2018-01-23Merge branch 'sb/submodule-update-reset-fix'Libravatar Junio C Hamano1-2/+17
When resetting the working tree files recursively, the working tree of submodules are now also reset to match. * sb/submodule-update-reset-fix: submodule: submodule_move_head omits old argument in forced case unpack-trees: oneway_merge to update submodules t/lib-submodule-update.sh: fix test ignoring ignored files in submodules t/lib-submodule-update.sh: clarify test
2018-01-23Merge branch 'ab/commit-m-with-fixup'Libravatar Junio C Hamano1-1/+8
"git commit --fixup" did not allow "-m<message>" option to be used at the same time; allow it to annotate resulting commit with more text. * ab/commit-m-with-fixup: commit: add support for --fixup <commit> -m"<extra message>" commit doc: document that -c, -C, -F and --fixup with -m error

2018-01-23Merge branch 'sb/diff-blobfind-pickaxe'Libravatar Junio C Hamano1-0/+68
"diff" family of commands learned "--find-object=<object-id>" option to limit the findings to changes that involve the named object. * sb/diff-blobfind-pickaxe: diff: use HAS_MULTI_BITS instead of counting bits manually diff: properly error out when combining multiple pickaxe options diffcore: add a pickaxe option to find a specific blob diff: introduce DIFF_PICKAXE_KINDS_MASK diff: migrate diff_flags.pickaxe_ignore_case to a pickaxe_opts bit diff.h: make pickaxe_opts an unsigned bit field
2018-01-23Merge branch 'jk/abort-clone-with-existing-dest'Libravatar Junio C Hamano1-26/+74
"git clone $there $here" is allowed even when here directory exists as long as it is an empty directory, but the command incorrectly removed it upon a failure of the operation. * jk/abort-clone-with-existing-dest: clone: do not clean up directories we didn't create clone: factor out dir_exists() helper t5600: modernize style t5600: fix outdated comment about unborn HEAD

2018-01-23Merge branch 'nd/ita-wt-renames-in-status'Libravatar Junio C Hamano1-0/+72
"git status" after moving a path in the working tree (hence making it appear "removed") and then adding with the -N option (hence making that appear "added") detected it as a rename, but did not report the old and new pathnames correctly. * nd/ita-wt-renames-in-status: wt-status.c: handle worktree renames wt-status.c: rename rename-related fields in wt_status_change_data wt-status.c: catch unhandled diff status codes wt-status.c: coding style fix Use DIFF_DETECT_RENAME for detect_rename assignments t2203: test status output with porcelain v2 format
