Karl Williamson [Sun, 12 Apr 2020 21:13:25 +0000 (15:13 -0600)]
t/harness: Add option for faster test suite execution

This commit adds an environment variable, PERL_TEST_HARNESS_ASAP, which
if set to non-zero increases the parallelism in the execution of the
test suite, speeding it up on systems with multiple cores.

Normally, there are two main test sections, one for core and the second
for non-core tests, and the testing of the non-core one doesn't begin
until the core tests are complete.  Within each section, there are a
number of test categories, like 're' for regular expressions, and
'JSON::PP' for the pure perl implementation of JSON.

Within each category, there are various single .t test files.  Some
categories can have those be tested in parallel; some require them to be
done in a particular order, say because an earlier .t does setup for
subsequent ones.  We already have this capability.

Completion of all the tests in a category is not needed before those of
another category can be started.  This is how it already works.

However, the core section categories are ordered so that they begin in a
logical order for someone trying to get perl to work.  First to start
are the basic sanity tests, then by roughly decreasing order of
widespread use in perl programs in the wild, with the final two
categories, porting and perf, being mainly of use to perl5 porters.
These two categories aren't started until all the tests in the earlier
categories are started.  We have some long running tests in those two
categories, and generally they delay the start of the entire second
section.

If those long running tests could be started sooner, shorter tests in
the first section could be run in parallel with them, increasing the
average CPU utilization, and the second section could begin (and hence
end) earlier, shortening the total elapsed execution time of the entire
suite.

The second section has some very long running tests.  JSON-PP is one of
them.  If it could run in parallel with tests from the first section,
that would also speed up the completion of the suite.

The environment variable added by this commit does both things.  The
basic sanity test categories in the first section continue to be started
before anything else.  But then all other tests are run in decreasing
order of elapsed time they take to run, removing the boundaries between
some categories, and between the two sections.

The gain from this increases as the number of jobs run in parallel does;
slower high core platforms have the highest increase.  On the old
dromedary with 24 cores, the gain is 20%, almost 2 minutes.  On my more
modern box with 12 cores, it is 8%.

TAP::Harness: Move timer initialization

This commit adds to blead the accepted PR
https://github.com/Perl-Toolchain-Gang/Test-Harness/pull/98
but the updated module has not been released.

This commit allows a many-core processor to run the Perl test suite more
efficiently.

Prior to this commit, the timers for counting elapsed time and CPU usage
were begun when a job's first output appears.  This yields inaccurate
results.  These results are saved in t/test_state for future runs so
that they can start the longest-running tests first, which leads to
using the available cores more efficiently.  (If you start a long running
test after everything else is nearly done, you have to wait for it to
finish before the suite as a whole is; if you start the long ones first,
and the shortest last, you don't have to wait very long for any
stragglers to complete.)  Inaccurate results here lead to this
situation, which we were often seeing in the podcheck.t test.

The worst case is if there is heavy computation at the beginning of the
test being run.  podcheck, for example, examines all the pods in the
directory structure to find which links to other pods do or do not have
corresponding anchors.  Output doesn't happen until the analysis is
complete.  On my system, this takes over 30 seconds, but prior to this
commit, what was noted was just the time required to do the output,
about 200 milliseconds.  The result was that podcheck was viewed as
being one of the shortest tests run, so was started late in the process,
and generally held up the completion of it.

This commit by itself doesn't improve the test completion very much,
because, test tests are run a whole directory at a time, and the
directory podcheck is in, for example, is run last.  The next commit
addresses that.

Graham Knop [Tue, 24 Nov 2020 20:27:43 +0000 (21:27 +0100)]
restore compatibility with old versions of ExtUtils::ParseXS

ExtUtils::ParseXS used to include a function called "errors", which was
documented. In was renamed to report_error_count in version 3.01 (perl
5.15.1) although the documentation wasn't fixed until 3.21 (perl 5.19.2).
As a documented function, this is a backwards compatibility issue.

It is possible for this to lead to errors when installing modules from
CPAN. If you are using the version of ExtUtils::ParseXS that comes with
core, between running the Makefile.PL and make, fulfilling prereqs can
result in upgrading ExtUtils::ParseXS. When Makefile.PL is run, the
generated Makefile gets the full path to xsubpp saved in it. Then when
upgraded from CPAN, ExtUtils::ParseXS and xsubpp will be in a new
location (site_perl or a local::lib). Running make will run the old
xsubpp, but it will then try to use the new ExtUtils::ParseXS which has
broken compatibility.

Restore the errors function as a compatibility shim to fix this.

Karl Williamson [Thu, 26 Nov 2020 01:20:28 +0000 (18:20 -0700)]
Avoid deadlock with PERL_MEM_LOG

This fixes GH #18341

The Perl wrapper for getenv() was changed in 5.32 to allocate memory to
squirrel safely away the result of the wrapped getenv() call.  It does
this while in a critical section so as to make sure another thread can't
interrupt it and destroy it.

Unfortunately, when Perl is compiled for debugging memory problems and
has PERL_MEM_LOG enabled, that allocation causes a recursive call to
getenv() for the purpose of checking an environment variable to see how
to log that allocation.  And hence it deadlocks trying to enter the
critical section.

There are various solutions.  One is to use or emulate a general semaphore
instead of a binary one.  This is effectively what
PL_lc_numeric_mutex_depth does for another mutex, and the code for that
could be used as a template.

But given that this is an extreme edge case which requires Perl to be
specially compiled to enable this feature which is used only for
debugging, a much simpler, if less safe if it were to ever be used in
production, solution should suffice.  Tony Cook suggested just avoiding
the wrapper for this particular purpose.

think it is worth the effort to use the native calls.

io/sem.t: eliminate warnings

This eliminates some warnings that semctl() (or other *ctl()) calls

- for IPC_STAT and GETALL, the current value of ARG is overwritten
  so making an undefined value warning for it nonsensical, so don't
  use SvPV_force().

- for other calls, ARG is either ignored, or in a behaviour
  introduced in perl 3 (along with the ops), treats the supplied
  value as an integer which is then converted to a pointer.  Rather
  than warning on an undef value which is most likely to be ignored
  we treat the undef as zero without the usual warning.

- always pass a number for SEMNUM in the test code

I didn't try to eliminate warning for non-numeric/undefined SEMNUM,
since while we know it isn't used by SETALL, GETALL, IPC_STAT and
IPC_SET, it may or may not be used by system defined *ctl() operators
such as SEM_INFO and SHM_LOCK on Linux.
