41 hours agoRT #127855] Slowdown in m//g on COW strings
David Mitchell [Mon, 2 May 2016 13:46:49 +0000]
RT #127855] Slowdown in m//g on COW strings

Better fix for this issue. The previous couple of commits revert an
earlier fix for this, which basically modified SvGROW or a particular
one of its callers to add 1 to the requested length to ensure that there
was space for any future COW reference count (which is stored in  spare
byte off the end of the string if SvCUR + null byte < SvLEN).

It turns out that sv_grow() already does a +1 over-allocation (added by me
with v5.19.0-442-gcbcb2a1), *except* that I made it skip the +1 if the
request size seemed to be a large power of two: with the idea being that
if someone had requested an exact big power of two then they were probably
doing something with buffers, and wouldn't want an 0x10000001 byte buffer
when they requested 0x10000000 bytes.  This was me basically being
conservative. However, I was probably too conservative: the simple test I
added just checked that bottom 8 bits were zero and if so, assumed that it
was a big buffer request. So as a side effect of this over-simple test,
something like 0x13d57f00 wouldn't be incremented to 0x13d57f01.

This is what was discovered in the original report in the the RT ticket:
strings allocated with lengths whose lower 8 bits were zero wouldn't have
space for a COW refcount, so would become much slower on things like

    while $g =~ m/0/g.

This commit improves the test so it only skips the +1 on lengths that
are an exact power of 2 and are greater than  0xfff.

two reverts had been done - those revertd being two preceding commits.

rt #113856: the flag -Werror=declaration-after-statement is seemingly
not working for clang (in OS X, not yet tested elsewhere), but working
as intended for gcc.  Since the system cc for OS X is clang (via Apple),
this failure to fail has been masked.

To restate: without this patch the Time-HiRes does not build in OS X
with gcc under usethreads.

3 weeks agoPATCH: [perl #127708] segfault in "$!" in threads
Karl Williamson [Sat, 9 Apr 2016 17:55:58 +0000]
PATCH: [perl #127708] segfault in "$!" in threads

This was showing up on Darwin because its setlocale is particularly not
thread safe.  But the problem is more generic.  Using locales just
isn't a good idea in a threaded application, as locales are
process-wide, not thread-specific.  Calling setlocale() changes the
locale of all threads at the same time.  Further the return of
setlocale() is a pointer to internal storage.  If you call setlocale()
just to learn what it currently is without actually changing the locale,
there is no guarantee that another thread won't interrupt your thread,
switching the locale to something else before you've had a chance to
copy it somewhere else for safekeeping, and the internal storage may
have been freed during that interruption, leading to things like
segfaults.

This is a problem that has been around in the locale handling code for a
long time.  I don't know why it hasn't shown up before, or maybe it has
and is not reproducible because it's timing dependent, and so any
problems didn't have tickets written for them, or were rejected as not
reproducible.

But the problem has been made worse in recent releases.  Only fairly
recently has perl changed so this problem can occur in programs that
don't use locale explicitly: ones that don't 'use locale' nor call
setlocale().  This ticket is for such a program that gets a
locale-related segfault, without ever touching locales itself.

I have done an audit of the perl source, looking for all such
occurrences, and this patch fixes all of them that I found.  The only
other ones, besides "$!", is in converting to/from UTF-8 in cygwin.c.
In all such cases, perl briefly switches the locale, does an operation,
then switches back.  The solution here is to add mutexes to make these
areas of code uninterruptible critical sections, so that they can rely
on having the locale be what they expect it to be during the entirety of
the operation, and can't have a setlocale() from another thread free
internal storage.  But this is not a general solution.  A thread
executing these sections can interrupt some other thread doing a
setlocale() and zap that.  However, we have long cautioned against doing
setlocales() in a thread, and that caution was strengthened in a commit
made yesterday, fc82b82ef4784a38877f35f56ee16f14934460ce.

The current commit should make safe all threaded programs that don't use
locales explicitly.

It's too close to the 5.24 release to do the rearchitecting required for
a general solution.  That would involve adding more critical sections.

POSIX 2008 introduced new locale handling functions that are
thread-safe, and affect only a single thread, and don't require mutexes.
The ultimate solution would be to use those tools where available, and
to hide from the outer code which set is being used.  Thus, perl would
be thread-safe on such platforms, while remaining problematic on older
ones, though fixed so segfaults wouldn't occur.  Tony Cook believes we
could emulate the newer behavior on all platforms at a significant
performance penalty.  I think this would require a lot of code, and
suspect there would be glitches in it for XS code.  But he may have
some ideas about how to do it simply.  In any case, this has to wait
until post 5.24.

Three other notes:

It seems to me that the cygwin code could be replaced by equivalent code
that doesn't use locales at all.  The comments in the source seem to
even indicate that.  I'll look into doing this in 5.25.

Another possible reason that this hasn't shown up in earlier perls is
that the problems may have been entirely affecting I/O operations and
there are already mutexes involving I/O, and so those could be
inadvertently protecting from, or at least minimizing, the problems
found here.  I haven't investigated to verify this.

This commit doesn't add a test.  I am asking on p5p for assistance in
writing one

3 weeks agonew perf test in pat.t: avoid timing failure
David Mitchell [Sat, 9 Apr 2016 12:17:21 +0000]
new perf test in pat.t: avoid timing failure

A new performance test in re/pat.t added by v5.23.9-58-gd14d585 could
occasionally fails to a timing issue. It was checking that the the
test took less than 1 sec to run; but since the clock usually has a
granularity of 1 sec, it could fail if the test ran over a tick boundary.

Change the condition to <= 1 sec, and increase the time the test takes on
a bad perl - it was taking 4sec on my system; it now takes about 14sec,
so there's less chance of a bad perl passing.
