2016-11-11t6026: clarify the point of "kill $(cat sleep.pid)"Libravatar Johannes Sixt1-1/+9
We lengthened the time the leftover process sleeps in the previous commit to make sure it will be there while 'git merge' runs and finishes. It therefore needs to be killed before leaving the test. And it needs to be killed even when 'git merge' fails, so it has to be triggered via test_when_finished mechanism. Explain all that in a large comment, and move the use site of test_when_finished to immediately before 'git merge' invocation, where the process is spawned.

2016-11-10t6026: ensure that long-running script really isLibravatar Johannes Schindelin1-4/+4
When making sure that background tasks are cleaned up in 5babb5b (t6026-merge-attr: clean up background process at end of test case, 2016-09-07), we considered to let the background task sleep longer, just to be certain that it will still be running when we want to kill it after the test. Sadly, the assumption appears not to hold true that the test case passes quickly enough to kill the background task within a second. Simply increase it to an hour. No system can be possibly slow enough to make above-mentioned assumption incorrect. Reported by Andreas Schwab.

2016-11-10Revert "t6026-merge-attr: don't fail if sleep exits early"Libravatar Junio C Hamano1-1/+1
This reverts commit 734fde2d7167e4b20d2ff6062ade3846949b0741. The point of the test is that the stray process was still running when 'git merge' did its thing through its completion, so a failure to "kill" it means we didn't give a condition to the test to trigger a possible future breakage. Appending "|| :" to the "kill" is sweeping a test-bug under the rug.

The Travis CI configuration we ship ran the tests with --verbose option but this risks non-TAP output that happens to be "ok" to be misinterpreted as TAP signalling a test that passed.

2016-10-27valgrind: support test helpersLibravatar René Scharfe2-3/+18
Tests run with --valgrind call git commands through a wrapper script that invokes valgrind on them. This script (valgrind.sh) is in turn invoked through symlinks created for each command in t/valgrind/bin/. Since e6e7530d (test helpers: move test-* to t/helper/ subdirectory) these symlinks have been broken for test helpers -- they point to the old locations in the root of the build directory. Fix that by teaching the code for creating the links about the new location of the binaries, and do the same in the wrapper script to allow it to find its payload.

2016-10-24test-lib: bail out when "-v" used under "prove"Libravatar Jeff King1-0/+10
When there is a TAP harness consuming the output of our test scripts, the "--verbose" breaks the output by mingling test command output with TAP. Because the TAP::Harness module used by "prove" is fairly lenient, this _usually_ works, but it violates the spec, and things get very confusing if the commands happen to output a line that looks like TAP (e.g., the word "ok" on its own line). Let's detect this situation and complain. Just calling error() isn't great, though; prove will tell us that the script failed, but the message doesn't make it through to the user. Instead, we can use the special TAP signal "Bail out!". This not only shows the message to the user, but instructs the harness to stop running the tests entirely. This is exactly what we want here, as the problem is in the command-line options, and every test script would produce the same error. The result looks like this (the first "Bailout called" line is in red if prove uses color on your terminal): $ make GIT_TEST_OPTS='--verbose --tee' rm -f -r 'test-results' *** prove *** Bailout called. Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log FAILED--Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log Makefile:39: recipe for target 'prove' failed make: *** [prove] Error 255 Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-10-21test-lib: add --verbose-log optionLibravatar Jeff King2-3/+25
The "--verbose" option redirects output from arbitrary test commands to stdout. This is useful for examining the output manually, like: ./t5547-push-quarantine.sh -v | less But it also means that the output is intermingled with the TAP directives, which can confuse a TAP parser like "prove". This has always been a potential problem, but became an issue recently when one test happened to output the word "ok" on a line by itself, which prove interprets as a test success: $ prove t5547-push-quarantine.sh :: -v t5547-push-quarantine.sh .. 1/? To dest.git * [new branch] HEAD -> master To dest.git ! [remote rejected] reject -> reject (pre-receive hook declined) error: failed to push some refs to 'dest.git' fatal: git cat-file d08c8eba97f4e683ece08654c7c8d2ba0c03b129: bad file t5547-push-quarantine.sh ..

Files=1, Tests=5, 0 wallclock secs ( 0.01 usr + 0.01 sys = 0.02 CPU) Result: FAIL One answer is "if it hurts, don't do it", but that's not quite the whole story. The Travis tests use "--verbose --tee" so that they can get the benefit of prove's parallel options, along with a verbose log in case there is a failure. We just need the verbose output to go to the log, but keep stdout clean. Getting this right turns out to be surprisingly difficult. Here's the progression of alternatives I considered: 1. Add an option to write verbose output to stderr. This is hard to capture, though, because we want each test to have its own log (because they're all run in parallel and the jumbled output would be useless). 2. Add an option to write verbose output to a file in test-results. This works, but the log is missing all of the non-verbose output, which gives context. 3. Like (2), but teach say_color() to additionally output to the log. This mostly works, but misses any output that happens outside of the say() functions (which isn't a lot, but is a potential maintenance headache). 4. Like (2), but make the log file the same as the "--tee" file. That almost works, but now we have two processes opening the same file. That gives us two separate descriptors, each with their own idea of the current position. They'll each start writing at offset 0, and overwrite each other's data. 5. Like (4), but in each case open the file for appending. That atomically positions each write at the end of the file. It's possible we may still get sheared writes between the two processes, but this is already the case when writing to stdout. It's not a problem in practice because the test harness generally waits for snippets to finish before writing the TAP output. We can ignore buffering issues with tee, because POSIX mandates that it does not buffer. Likewise, POSIX specifies "tee -a", so it should be available everywhere. This patch implements option (5), which seems to work well in practice. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-10-20t3700: fix broken test under !SANITYLibravatar Junio C Hamano1-0/+1
An "add --chmod=+x" test recently added by 610d55af0f ("add: modify already added files when --chmod is given", 2016-09-14) used "xfoo3" as a test file. The paths xfoo[1-3] were used by earlier tests for symbolic links but they were expected to have been removed by the time the execution reached this new test. The removal with "git reset --hard" however happened in a pair of earlier tests, both of which are protected by POSIXPERM,SANITY prerequisites. Platforms and test environments that lacked these would have seen xfoo3 as a leftover symbolic link that points at somewhere else at this point of the sequence, and the chmod test would have given a wrong result.

2016-10-14fetch: use "quick" has_sha1_file for tag followingLibravatar Jeff King1-0/+99
When we auto-follow tags in a fetch, we look at all of the tags advertised by the remote and fetch ones where we don't already have the tag, but we do have the object it peels to. This involves a lot of calls to has_sha1_file(), some of which we can reasonably expect to fail. Since 45e8a74 (has_sha1_file: re-check pack directory before giving up, 2013-08-30), this may cause many calls to reprepare_packed_git(), which is potentially expensive. This has gone unnoticed for several years because it requires a fairly unique setup to matter: 1. You need to have a lot of packs on the client side to make reprepare_packed_git() expensive (the most expensive part is finding duplicates in an unsorted list, which is currently quadratic). 2. You need a large number of tag refs on the server side that are candidates for auto-following (i.e., that the client doesn't have). Each one triggers a re-read of the pack directory. 3. Under normal circumstances, the client would auto-follow those tags and after one large fetch, (2) would no longer be true. But if those tags point to history which is disconnected from what the client otherwise fetches, then it will never auto-follow, and those candidates will impact it on every fetch. So when all three are true, each fetch pays an extra O(nr_tags * nr_packs^2) cost, mostly in string comparisons on the pack names. This was exacerbated by 47bf4b0 (prepare_packed_git_one: refactor duplicate-pack check, 2014-06-30) which uses a slightly more expensive string check, under the assumption that the duplicate check doesn't happen very often (and it shouldn't; the real problem here is how often we are calling reprepare_packed_git()). This patch teaches fetch to use HAS_SHA1_QUICK to sacrifice accuracy for speed, in cases where we might be racy with a simultaneous repack. This is similar to the fix in 0eeb077 (index-pack: avoid excessive re-reading of pack directory, 2015-06-09). As with that case, it's OK for has_sha1_file() occasionally say "no I don't have it" when we do, because the worst case is not a corruption, but simply that we may fail to auto-follow a tag that points to it. Here are results from the included perf script, which sets up a situation similar to the one described above: Test HEAD^ HEAD ---------------------------------------------------------- 5550.4: fetch 11.21(10.42+0.78) 0.08(0.04+0.02) -99.3% Reported-by: Vegard Nossum <vegard.nossum@oracle.com> Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-10-14parse_mailboxes: accept extra text after <...> addressLibravatar Matthieu Moy1-0/+29
The test introduced in this commit succeeds without the patch to Git.pm if Mail::Address is installed, but fails otherwise because our in-house parser does not accept any text after the email address. They succeed both with and without Mail::Address after this commit. Mail::Address accepts extra text and considers it as part of the name, iff the address is surrounded with <...>. The implementation mimics this behavior as closely as possible. This mostly restores the behavior we had before b1c8a11 (send-email: allow multiple emails using --cc, --to and --bcc, 2015-06-30), but we keep the possibility to handle comma-separated lists.

However, if the reflog for the base branch is totally empty (as it commonly is right after cloning, which does not write a reflog entry), then our for_each_reflog call will not find any entries, and we will come up with no merge base, even though there may be one with the current tip of the base.

2016-10-10files_read_raw_ref: avoid infinite loop on broken symlinksLibravatar Jeff King1-0/+5
Our ref resolution first runs lstat() on any path we try to look up, because we want to treat symlinks specially (by resolving them manually and considering them symrefs). But if the results of `readlink` do _not_ look like a ref, we fall through to treating it like a normal file, and just read the contents of the linked path. Since fcb7c76 (resolve_ref_unsafe(): close race condition reading loose refs, 2013-06-19), that "normal file" code path will stat() the file and if we see ENOENT, will jump back to the lstat(), thinking we've seen inconsistent results between the two calls. But for a symbolic ref, this isn't a race: the lstat() found the symlink, and the stat() is looking at the path it points to. We end up in an infinite loop calling lstat() and stat(). We can fix this by avoiding the retry-on-inconsistent jump when we know that we found a symlink. While we're at it, let's add a comment explaining why the symlink case gets to this code in the first place; without that, it is not obvious that the correct solution isn't to avoid the stat() code path entirely.

2016-09-21regex: use regexec_buf()Libravatar Johannes Schindelin1-1/+1
The new regexec_buf() function operates on buffers with an explicitly specified length, rather than NUL-terminated strings. We need to use this function whenever the buffer we want to pass to regexec(3) may have been mmap(2)ed (and is hence not NUL-terminated). Note: the original motivation for this patch was to fix a bug where `git diff -G <regex>` would crash. This patch converts more callers, though, some of which allocated to construct NUL-terminated strings, or worse, modified buffers to temporarily insert NULs while calling regexec(3). By converting them to use regexec_buf(), the code has become much cleaner. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-09-21regex: -G<pattern> feeds a non NUL-terminated string to regexec() and failsLibravatar Johannes Schindelin1-0/+22
When our pickaxe code feeds file contents to regexec(), it implicitly assumes that the file contents are read into implicitly NUL-terminated buffers (i.e. that we overallocate by 1, appending a single '\0'). This is not so. In particular when the file contents are simply mmap()ed, we can be virtually certain that the buffer is preceding uninitialized bytes, or invalid pages. Note that the test we add here is known to be flakey: we simply cannot know whether the byte following the mmap()ed ones is a NUL or not. Typically, on Linux the test passes. On Windows, it fails virtually every time due to an access violation (that's a segmentation fault for you Unix-y people out there). And Windows would be correct: the regexec() call wants to operate on a regular, NUL-terminated string, there is no NUL in the mmap()ed memory range, and it is undefined whether the next byte is even legal to access. When run with --valgrind it demonstrates quite clearly the breakage, of course. Being marked with `test_expect_failure`, this test will sometimes be declare "TODO fixed", even if it only passes by mistake. This test case represents a Minimal, Complete and Verifiable Example of a breakage reported by Chris Sidi.

2016-09-21t3700-add: create subdirectory gentlyLibravatar Johannes Sixt1-1/+1
The subdirectory 'sub' is created early in the test file. Later, a test case removes it during its clean-up actions. However, this test case is protected by POSIXPERM. Consequently, 'sub' remains when the POSIXPERM prerequisite is not satisfied. Later, a recently introduced test case creates 'sub' again. Use -p with mkdir so that it does not fail if 'sub' already exists. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-09-21checkout: fix ambiguity check in subdirLibravatar Nguyễn Thái Ngọc Duy2-0/+21
The two functions in parse_branchname_arg(), verify_non_filename and check_filename, need correct prefix in order to reconstruct the paths and check for their existence. With NULL prefix, they just check paths at top dir instead. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
