- Drop patch-Colo_ecb.h
(It was "Use __builtin_unreachable on Clang instead of the broken C11 hack.",
and now upstream takes care.)
(upstream)
- Update 6.41 to 6.42
-------------------
6.42 Wed Feb 11 20:29:52 CET 2015
- Coro::SemaphoreSet->try did not actually work (analyzed by
SATO Kentaro).
- upgrade libecb to be C11 compliant.
6.41 Sat Sep 6 22:08:46 CEST 2014
- restore portability to perl 5.8.x.
- give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
up some memory, but fixes "use feature" and similar modules
when used inside a Coro.
- allow zero as argument to Coro::Channel to mean the same thing
as no argument. this works with older versions as well,
but wasn't legal until now.
- slightly better c header file detection.
- work around more incompatible changes in 5.20.
- check that perl slots actually have enough space to hold
interpreter variables.
- untested port to perl 5.19 (64 bit tmps indices) (reported
by Andreas König).
- croak when cancel is called without a thread context.
- *sigh*, removed leftover debugging code from debugging a
perl bug, of all things.
- semaphores would not clear the destroy hook when interrupted
by ->throw, causing segfaults or worse.
- ->throw on a thread waiting for a semaphore did not acquire
the semaphore, but also didn't wake up other waiters,
possibly causing a deadlock.
- "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
to report a full stacktrace, which should help find out
where the actual call is.
- "atomically" destroy data in slf_destroy, because it is
the right thing to do, just in case.
- disable ecb.h libm dependency, to compile on ancient systems
or under adverse conditions.
- do not crash when freeing padlists with holes (in 5.18).
- tentative SVt_BIND 5.19 port/fix.
- use a new algorithm to derive padlists for perl 5.18. The old
one could lead to 0-pointer accesses inside perl (reported
by Darin McBride).
Not a leaf, but this update should fix a handful of depending
packages, and at least one of those passes its tests against this
version.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
Revision history for Perl extension Coro.
6.31 Thu May 9 07:39:48 CEST 2013
- Coro::AIO requests would crash if the thread was ready'd
while the request was ongoing.
6.29 Wed May 8 02:55:18 CEST 2013
- when an on_destroy handler destructs the coro currently being
destructed a perl scalar could be accessed after being freed,
likely causing a crash.
6.28 Wed Mar 6 06:58:02 CET 2013
- clean remnants of existing __DIE__ and __WARN__ handlers so
they lose their magic and will not cause segfaults later
(testcase by Andrey Sagulin).
- improved Coro::State documentation a bit.
- Coro::Debug::command now flushes the output.
- add hack detection code for x32 abi, because the braindead slugs
who designed that made it look exactly like x86_64 without
providing proper compile time symbols to test for it. as a result,
this detection cannot work reliably.
- valgrind stack registering was broken.
- do not rely on Time::HiRes anymore in Coro::Debug.
6.23 Fri Dec 7 23:36:37 CET 2012
- use experimental fiber implementation on native windows
perls.
- use sizeof (void *) as multiplication factor for stack sizes,
to accomodate the totally braindamaged microsoft 64 bit "os".
- changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
activeperl 5.16 crashes when PerlIO_define_layer is called due
to some bug in the perl dll, strawberry perl at least passes
the testsuite.
- implement Coro::Handle->peeraddr/host/port, for slightly
improved compatibility with LWP.
- implement 5.17 compatibility by almost blindly applying a
good-looking patch by Father Chrysostomos.
- move stack management functions into libcoro 3.
- libcoro version 3 "released".
- support magic values as timed_io_once args.
- recommend AnyEvent 7+ or EV 4+, also require EV
version 4 or newer for Coro::EV.
6.10 Tue Oct 9 01:14:27 CEST 2012
- updated ecb.h, it had a typo that caused it to not compile on many
big endian systems (reported by many people).
- disable memory fences in ecb.h to improve portability.
6.09 Sat Oct 6 23:25:02 CEST 2012
- Coro::EV I/O watchers were not interruptible by exceptions
(Coro::State::throw) (testcase by sten).
- ->throw now puts threads into the ready queue, as this seems to
be expected by existing code, and code that doesn't cope with spurious
wakeups needs fixing anyway.
- use fd -1 in mmap.
- cast I32 to int in error message printf.
- warn about broken so-called "hardened" kernels.
6.08 Fri Apr 13 12:05:47 CEST 2012
- be more aggressive about exiting like perl does - formerly,
exiting from the non-main thread would not execute END blocks.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
Changes from previous:
----------------------
6.07 Fri Nov 11 21:21:48 CET 2011
- work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
- update ecb.h.
5.25 Thu Nov 11 01:08:39 CET 2010
- try a different approach on netbsd - netbsd 5 finally has marginally
working pthreads, but still broken ucontext/sigaltstack.
- openbsd 4.8 finally got their act together, Coro works out of the box
with asm, setjmp and pthreads (no change, just informational).
5.24 Sat Oct 23 11:27:12 CEST 2010
- port to the EV 4.0 API.
- work around bugs in mingw32, making strawberry perl work
out of the box.
- correctly modify Coro::AIO function prototypes
so that they reflect the "no optional parameters" rule.
- "ported" libcoro to C++.
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.
sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!
Upstream changes:
5.23 Mon May 17 18:50:42 CEST 2010
- be more resistant to ordering changes when initialising
Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
Waldorf).
- document that perl 5.12 deliberately removed support for cloning.
Collection.
The Perl 5 module collection Coro manages continuations in general,
most often in the form of cooperative threads.The specific flavor
of thread offered by this module also guarantees you that it will
not switch between threads unless necessary, at easily-identified
points in your program, so locking and parallel access are rarely
an issue, making thread programming much safer and easier than using
other thread models.
