Running test scripts under -x option of the shell is often not a
useful way to debug them, because the error messages from the
commands tests try to capture and inspect are contaminated by the
tracing output by the shell. An earlier work done to make it more
pleasant to run tests under -x with recent versions of bash is
extended to cover posix shells that do not support BASH_XTRACEFD.

travis-ci: run tests with '-x' tracing

Explain in 't/README' why it is a bad idea to redirect and verify the
stderr of compound commands, in the hope that future contributions
will follow this advice and the test suite will keep working with '-x'
tracing and /bin/sh.
While at it, since we can now run the test suite with '-x' without
needing a Bash version supporting BASH_XTRACEFD, remove the now
outdated caution note about non-Bash shells from the description of
the '-x' option.

The previous patch resolved most of the test failures caused by
running our test suite with '-x' tracing and /bin/sh, and the
following patches in this series will resolve almost all of the
remaining failures. Unfortunately, not yet all.
Add means to disable '-x' tracing for individual test scripts by
setting the $test_untraceable variable to a non-empty value in the
test script before sourcing 'test-lib.sh'. However, since '-x'
tracing is not an issue with recent Bash versions supporting
BASH_XTRACEFD, i.e. v4.1 and later, don't disable tracing when the
test script is run with such a Bash version even when
$test_untraceable is set.

Add LIBPCRE1 and LIBPCRE2 prerequisites which are true when git is
compiled with USE_LIBPCRE1=YesPlease or USE_LIBPCRE2=YesPlease,
respectively.
The syntax of PCRE1 and PCRE2 isn't the same in all cases (see
pcresyntax(3) and pcre2syntax(3)). If test are added that test for
those they'll need to be guarded by these new prerequisites.
The subsequent patch will make use of LIBPCRE2, so LIBPCRE1 isn't
strictly needed for now, but let's add it for consistency and so that
checking for it doesn't have to be done with the less obvious "PCRE,
!LIBPCRE2", which while semantically the same is more confusing, and
would lead to bugs if PCRE v3 is ever released as the tests would mean
v1, not any non-v2 version.

Rename the LIBPCRE prerequisite to PCRE. This is for preparation for
libpcre2 support, where having just "LIBPCRE" would be confusing as it
implies v1 of the library.
None of these tests are incompatible between versions 1 & 2 of
libpcre, it's less confusing to give them a more general name to make
it clear that they work on both library versions.

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
|
|
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

Bad plan. You planned 4 tests but ran 5.
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.

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. When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.

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).

It's easy to miss an "&&"-chain in a test script, like:
test_expect_success 'check something important' '
cmd1 &&
cmd2
cmd3
'
The test harness will notice if cmd3 fails, but a failure of
cmd1 or cmd2 will go unnoticed, as their exit status is lost
after cmd3 runs.
The toy example above is easy to spot because the "cmds" are
all the same length, but real code is much more complicated.
It's also difficult to detect these situations by statically
analyzing the shell code with regexps (like the
check-non-portable-shell script does); there's too much
context required to know whether a &&-chain is appropriate
on a given line or not.
This patch instead lets the shell check each test by
sticking a command with a specific and unusual return code
at the top of each test, like:
(exit 117) &&
cmd1 &&
cmd2
cmd3
In a well-formed test, the non-zero exit from the first
command prevents any of the rest from being run, and the
test's exit code is 117. In a bad test (like the one above),
the 117 is lost, and cmd3 is run.
When we encounter a failure of this check, we abort the test
script entirely. For one thing, we have no clue which subset
of the commands in the test snippet were actually run.
Running further tests would be pointless, because we're now
in an unknown state. And two, this is not a "test failure"
in the traditional sense. The test script is buggy, not the
code it is testing. We should be able to fix these problems
in the script once, and not have them come back later as a
regression in git's code.
After checking a test snippet for --chain-lint, we do still
run the test itself. We could actually have a pure-lint
mode which just checks each test, but there are a few
reasons not to. One, because the tests are executing
arbitrary code, which could impact the later environment
(e.g., that could impact which set of tests we run at all).
And two, because a pure-lint mode would still be expensive
to run, because a significant amount of code runs outside of
the test_expect_* blocks. Instead, this option is designed
to be used as part of a normal test suite run, where it adds
very little overhead.
Turning on this option detects quite a few problems in
existing tests, which will be fixed in subsequent patches.
However, there are a number of places it cannot reach:
- it cannot find a failure to break out of loops on error,
like:
cmd1 &&
for i in a b c; do
cmd2 $i
done &&
cmd3
which will not notice failures of "cmd2 a" or "cmd b"
- it cannot find a missing &&-chain inside a block or
subfunction, like:
foo () {
cmd1
cmd2
}
foo &&
bar
which will not notice a failure of cmd1.
- it only checks tests that you run; every platform will
have some tests skipped due to missing prequisites,
so it's impossible to say from one run that the test
suite is free of broken &&-chains. However, all tests get
run by _somebody_, so eventually we will notice problems.
- it does not operate on test_when_finished or prerequisite
blocks. It could, but these tends to be much shorter and
less of a problem, so I punted on them in this patch.

Usually running a test under "-v" makes it clear which
command is failing. However, sometimes it can be useful to
also see a complete trace of the shell commands being run in
the test. You can do so without any support from the test
suite by running "sh -x tXXXX-foo.sh". However, this
produces quite a large bit of output, as we see a trace of
the entire test suite.
This patch instead introduces a "-x" option to the test
scripts (i.e., "./tXXXX-foo.sh -x"). When enabled, this
turns on "set -x" only for the tests themselves. This can
still be a bit verbose, but should keep things to a more
manageable level. You can even use "--verbose-only" to see
the trace only for a specific test.
The implementation is a little invasive. We turn on the "set
-x" inside the "eval" of the test code. This lets the eval
itself avoid being reported in the trace (which would be
long, and redundant with the verbose listing we already
showed). And then after the eval runs, we do some trickery
with stderr to avoid showing the "set +x" to the user.
We also show traces for test_cleanup functions (since they
can impact the test outcome, too). However, we do avoid
running the noop ":" cleanup (the default if the test does
not use test_cleanup at all), as it creates unnecessary
noise in the "set -x" output.

* jk/wrap-perl-used-in-tests:
t: use perl instead of "$PERL_PATH" where applicable
t: provide a perl() function which uses $PERL_PATH
|
|
Once upon a time, we assumed that calling a bare "perl" in
the test scripts was OK, because we would find the perl from
the user's PATH, and we were only asking that perl to do
basic operations that work even on old versions of perl.
Later, we found that some systems really prefer to use
$PERL_PATH even for these basic cases, because the system
perl misbehaves in some way (e.g., by handling line endings
differently). We then switched "perl" invocations to
"$PERL_PATH" to respect the user's choice.
Having to use "$PERL_PATH" is ugly and cumbersome, though.
Instead, let's provide a perl() shell function that tests
can use, which will transparently do the right thing.
Unfortunately, test writers still have to use $PERL_PATH in
certain situations, so we still need to keep the advice in
the README.
Note that this may fix test failures in t5004, t5503, t6002,
t6003, t6300, t8001, and t8002, depending on your system's
perl setup. All of these can be detected by running:

The git build system supports a NO_PERL switch to avoid installing
perl bindings or other features (like "git add --patch") that rely on
perl on runtime, but even with NO_PERL it has not been possible for a
long time to run tests without perl. Helpers such as
nul_to_q () {
"$PERL_PATH" -pe 'y/\000/Q/'
}
use perl as a better tr or sed and are regularly used in tests without
worrying to add a PERL prerequisite.
Perl is portable enough that it seems fine to keep relying on it for
this kind of thing in tests (and more readable than the alternative of
trying to find POSIXy equivalents). Update the test documentation to
clarify this.

With the new --verbose-only=<pattern> option, one can enable --verbose
at a per-test granularity. The pattern is matched against the test
number, e.g.
./t0000-basic.sh --verbose-only='2[0-2]'
to see only the full output of test 20-22, while showing the rest in the
one-liner format.
As suggested by Jeff King, this takes care to wrap the entire
test_expect_* block, but nothing else, in the verbose toggling. We
can use the test_start/end functions from the previous commit for the
purpose.

With --valgrind=memcheck-fast, the tests run under memcheck but
without the autodetected --track-origins. If you just run valgrind to
see *if* there is any memory issue with your program, the extra
information is not needed, and it comes at a roughly 30% hit in
runtime.
While it is possible to achieve the same through GIT_VALGRIND_OPTIONS,
this should be more discoverable and hopefully encourage more users to
run their tests with valgrind.

Running tests under helgrind and DRD recently proved useful in
tracking down thread interaction issues. This can unfortunately not
be done through GIT_VALGRIND_OPTIONS because any tool other than
memcheck would complain about unknown options.
Let --valgrind take an optional parameter that describes the valgrind
tool to invoke. The default mode is to run memcheck as before.

UTF8 behaviour of the filesystem (conversion from nfd to nfc) plays a
role in several tests and is tested in several tests. Therefore, move
the test from t0050 into the test lib and use the prerequisite in t0050.

Add a few more advices that we often have to give to new test
writers.
Also update an example where a double quote pair is used to enclose
a test body to use a single quote pair, which is more readable and
more importantly gives saner semantics for variable substitution.
