2017-05-26grep: change the internal PCRE macro names to be PCRE1Libravatar Ævar Arnfjörð Bjarmason1-1/+1
Change the internal USE_LIBPCRE define, & build options flag to use a naming convention ending in PCRE1, without changing the long-standing USE_LIBPCRE Makefile flag which enables this code. This is for preparation for libpcre2 support where having things like USE_LIBPCRE and USE_LIBPCRE2 in any more places than we absolutely need to for backwards compatibility with old Makefile arguments would be confusing. In some ways it would be better to change everything that now uses USE_LIBPCRE to use USE_LIBPCRE1, and to make specifying USE_LIBPCRE (or --with-pcre) an error. This would impose a one-time burden on packagers of git to s/USE_LIBPCRE/USE_LIBPCRE1/ in their build scripts. However I'd like to leave the door open to making USE_LIBPCRE=YesPlease eventually mean USE_LIBPCRE2=YesPlease, i.e. once PCRE v2 is ubiquitous enough that it makes sense to make it the default. This code and the USE_LIBPCRE Makefile argument was added in commit 63e7e9d8b6 ("git-grep: Learn PCRE", 2011-05-09). At the time there was no indication that the PCRE project would release an entirely new & incompatible API around 3 years later.

2017-05-18test: allow skipping the remainderLibravatar Junio C Hamano1-8/+13
Because TAP output does not like to see the remainder of the test getting skipped after running one or more tests, bf4b7219 ("test-lib.sh: Add check for invalid use of 'skip_all' facility", 2012-09-01) made sure that test_done errors out when this happens. Instead, loosen the check so that we only pretend that the rest of the test script did not exist in such a case. We'd lose a bit of information (i.e. TAP does not notice that we are skipping some tests), but not very much (i.e. TAP wasn't told how many tests are skipped anyway). This will allow inclusion of lib-httpd.sh in the middle of a test, which will skip the remainder of the test scripts when tests that involve web server are declined with GIT_TEST_HTTPD=false, for example.

2017-04-24test-lib: retire $remove_trash variableLibravatar Junio C Hamano1-6/+4
The convention "$remove_trash is set to the trash directory that is used during the test, so that it will be removed at the end, but under --debug option we set the varilable to empty string to preserve the directory" made sense back when it was introduced, as there was no $TRASH_DIRECTORY variable. These days, since no tests looks at the variable, it is obscure and even risks that by mistake the variable gets used for something else (e.g. remove_trash=yes) and cause us misbehave. Worse yet, remove_trash was not initialized to an empty string at the beginning, so a stray environment variable the user has could have affected the logic when "--debug" is in use. Rewrite the clean-up sequence in test_done helper to explicitly check the $debug condition and remove the trash directory using the $TRASH_DIRECTORY variable. Note that "go to the directory one level above the trash and then remove it" is kept and this is deliverate; test_at_end_hook_ will keep running from the expected location, and also some platforms may not like a directory that is serving as the $cwd of a still-active process removed.

There was no problem under "--debug", where the variable is left empty, as the first "test -d $remove_trash" would have said "No, it doesn't".

2017-04-23test-lib: abort when can't remove trash directoryLibravatar SZEDER Gábor1-2/+5
We had two similar bugs in the tests sporadically triggering error messages during the removal of the trash directory, see commits bb05510e5 (t5510: run auto-gc in the foreground, 2016-05-01) and ef09036cf (t6500: wait for detached auto gc at the end of the test script, 2017-04-13). The test script succeeded nonetheless, because these errors are ignored during housekeeping in 'test_done'. However, such an error is a sign that something is fishy in the test script. Print an error message and abort the test script when the trash directory can't be removed successfully or is already removed, because that's unexpected and we would prefer somebody notice and figure out why.

2017-04-20t0006 & t5000: skip "far in the future" test when time_t is too limitedLibravatar Johannes Schindelin1-0/+1
Git's source code refers to timestamps as unsigned long, which is ill-defined, as there is no guarantee about the number of bits that data type has. In preparation of switching to another data type that is large enough to hold "far in the future" dates, we need to prepare the t0006-date.sh script for the case where we *still* cannot format those dates if the system library uses 32-bit time_t.

2017-04-20t0006 & t5000: prepare for 64-bit timestampsLibravatar Johannes Schindelin1-0/+2
Git's source code refers to timestamps as unsigned longs. On 32-bit platforms, as well as on Windows, unsigned long is not large enough to capture dates that are "absurdly far in the future". It is perfectly valid by the C standard, of course, for the `long` data type to refer to 32-bit integers. That is why the `time_t` data type exists: so that it can be 64-bit even if `long` is 32-bit. Git's source code simply uses an incorrect data type for timestamps, is all. The earlier quick fix 6b9c38e14cd (t0006: skip "far in the future" test when unsigned long is not long enough, 2016-07-11) papered over this issue simply by skipping the respective test cases on platforms where they would fail due to the data type in use. This quick fix, however, tests for *long* to be 64-bit or not. What we need, though, is a test that says whether *whatever data type we use for timestamps* is 64-bit or not. The same quick fix was used to handle the similar problem where Git's source code uses `unsigned long` to represent size, instead of `size_t`, conflating the two issues. So let's just add another prerequisite to test specifically whether timestamps are represented by a 64-bit data type or not. Later, after we switch to a larger data type, we can flip that prerequisite to test `time_t` instead of `long`.

2017-03-23tests: lint for run-away here-docLibravatar Junio C Hamano1-3/+3
We found a few run-away here documents that are started with an end-of-here-doc marker that is incorrectly spelled, e.g. git some command >actual && cat <<EOF >expect ... EOF && test_cmp expect actual which ends up slurping the entire remainder of the script as if it were the data. Often the command that gets misused like this exits without failure (e.g. "cat" in the above example), which makes the command appear to work, without ever executing the remainder of the test.

2017-03-18tests: create an interactive gdb session with the 'debug' helperLibravatar SZEDER Gábor1-0/+1
The 'debug' test helper is supposed to facilitate debugging by running a command of the test suite under gdb. Unfortunately, its usefulness is severely limited, because that gdb session is not interactive, since the test's, and thus gdb's standard input is redirected from /dev/null (for a good reason, see 781f76b15 (test-lib: redirect stdin of tests, 2011-12-15)). Redirect gdb's standard file descriptors from/to the test environment's stdin, stdout and stderr in the 'debug' helper, thus creating an interactive gdb session (even in non-verbose mode), which is much, much more useful.

2016-10-26Merge branch 'jk/tap-verbose-fix'Libravatar Junio C Hamano1-4/+30
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. This resulted in unnecessary failure. This has been corrected by introducing a new mode to run our tests in the test harness to send the verbose output separately to the log file. * jk/tap-verbose-fix: test-lib: bail out when "-v" used under "prove" travis: use --verbose-log test option test-lib: add --verbose-log option test-lib: handle TEST_OUTPUT_DIRECTORY with spaces
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 King1-3/+19
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 ..

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>

2016-08-30test-lib: drop PID from test-results/*.countLibravatar Jeff King1-2/+2
Each test run generates a "count" file in t/test-results that stores the number of successful, failed, etc tests. If you run "t1234-foo.sh", that file is named as "t/test-results/t1234-foo-$$.count" The addition of the PID there is serving no purpose, and makes analysis of the count files harder. The presence of the PID dates back to 2d84e9f (Modify test-lib.sh to output stats to t/test-results/*, 2008-06-08), but no reasoning is given there. Looking at the current code, we can see that other files we write to test-results (like *.exit and *.out) do _not_ have the PID included. So the presence of the PID does not meaningfully allow one to store the results from multiple runs anyway. Moreover, anybody wishing to read the *.count files to aggregate results has to deal with the presence of multiple files for a given test (and figure out which one is the most recent based on their timestamps!). The only consumer of these files is the aggregate.sh script, which arguably gets this wrong. If a test is run multiple times, its counts will appear multiple times in the total (I say arguably only because the desired semantics aren't documented anywhere, but I have trouble seeing how this behavior could be useful). So let's just drop the PID, which fixes aggregate.sh, and will make new features based around the count files easier to write. Note that since the count-file may already exist (when re-running a test), we also switch the "cat" from appending to truncating. The use of append here was pointless in the first place, as we expected to always write to a unique file. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Running tests with '-x' option to trace the individual command executions is a useful way to debug test scripts, but some tests that capture the standard error stream and check what the command said can be broken with the trace output mixed in.

2016-05-11test-lib: set BASH_XTRACEFD automaticallyLibravatar Jeff King1-0/+13
Passing "-x" to a test script enables the shell's "set -x" tracing, which can help with tracking down the command that is causing a failure. Unfortunately, it can also _cause_ failures in some tests that redirect the stderr of a shell function. Inside the function the shell continues to respect "set -x", and the trace output is collected along with whatever stderr is generated normally by the function. You can see an example of this by running: ./t0040-parse-options.sh -x -i which will fail immediately in the first test, as it expects: test_must_fail some-cmd 2>output.err to leave output.err empty (but with "-x" it has our trace output). Unfortunately there isn't a portable or scalable solution to this. We could teach test_must_fail to disable "set -x", but that doesn't help any of the other functions or subshells. However, we can work around it by pointing the "set -x" output to our descriptor 4, which always points to the original stderr of the test script. Unfortunately this only works for bash, but it's better than nothing (and other shells will just ignore the BASH_XTRACEFD variable). The patch itself is a simple one-liner, but note the caveats in the accompanying comments. Automatic tests for our "-x" option may be a bit too meta (and a pain, because they are bash-specific), but I did confirm that it works correctly both with regular "-x" and with "--verbose-only=1". This works because the latter flips "set -x" off and on for particular tests (if it didn't, we would get tracing for all tests, as going to descriptor 4 effectively circumvents the verbose flag).

2016-04-22test-lib: simplify '--option=value' parsingLibravatar SZEDER Gábor1-5/+5
To get the 'value' from '--option=value', test-lib.sh parses said option running 'expr' with a regexp. This involves a subshell, an external process, and a lot of non-alphanumeric characters in the regexp. Use a much simpler POSIX-defined shell parameter expansion instead to do the same.

2016-02-02test-lib: limit the output of the yes utilityLibravatar Johannes Schindelin1-2/+4
On Windows, there is no SIGPIPE. A consequence of this is that the upstream process of a pipe does not notice the death of the downstream process until the pipe buffer is full and writing more data returns an error. This behavior is the reason for an annoying delay during the execution of t7610-mergetool.sh: There are a number of test cases where 'yes' is invoked upstream. Since the utility is basically an endless loop it runs, on Windows, until the pipe buffer is full. This does take a few seconds. The test suite has its own implementation of 'yes'. Modify it to produce only a limited amount of output that is sufficient for the test suite. The amount chosen should be sufficiently high for any test case, assuming that future test cases will not exaggerate their demands of input from an upstream 'yes' invocation.

2016-01-27mingw: disable mkfifo-based testsLibravatar Johannes Schindelin1-1/+1
MSYS2 (the POSIX emulation layer used by Git for Windows' Bash) actually has a working mkfifo. The only problem is that it is only emulating named pipes through the MSYS2 runtime; The Win32 API has no idea about named pipes, hence the Git executable cannot access those pipes either. The symptom is that Git fails with a '<name>: No such file or directory' because MSYS2 emulates named pipes through special-crafted '.lnk' files. The solution is to tell the test suite explicitly that we cannot use named pipes when we want to test on Windows. This lets t4056-diff-order.sh, t9010-svn-fe.sh and t9300-fast-import.sh pass.
