7TODO: tutorial 86.09 Sat Oct 6 23:25:02 CEST 2012
8TODO: in_eval, PL_tained 9 - Coro::EV I/O watchers were not interruptible by exceptions
10 (Coro::State::throw) (testcase by sten).
11 - ->throw now puts threads into the ready queue, as this seems to
12 be expected by existing code, and code that doesn't cope with spurious
13 wakeups needs fixing anyway.
14 - use fd -1 in mmap.
15 - cast I32 to int in error message printf.
16 - warn about broken so-called "hardened" kernels.
17
186.08 Fri Apr 13 12:05:47 CEST 2012
19 - be more aggressive about exiting like perl does - formerly,
20 exiting from the non-main thread would not execute END blocks.
21
226.07 Fri Nov 11 21:21:48 CET 2011
23 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
24 - update ecb.h.
25
266.06 Mon Aug 8 23:59:48 CEST 2011
27 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
28 backend, which is an order of magnitude slower. unfortunately, cygwins
29 pthread implementation isn't very complete either, so allocate the stack
30 twice just to be sure.
31 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
32 in its ithreaded perl - best recompile cygwin and use the 'w'indows
33 backend for much better performance. also disable ithreads for
34 even better performance...).
35
366.05 Thu Aug 4 21:36:36 CEST 2011
37 - blush, condvar values would not be propagated from send to recv anymore
38 (reported by Chip Salzenberg).
39 - use exponential increase for the readline buffer length in
40 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
41
426.04 Wed Aug 3 17:15:45 CEST 2011
43 - use even more efficient and more compatible condvars for
44 compatibility to AnyEvent 6.x :)
45 - more inconsequential ecb.h updates.
46
476.03 Wed Aug 3 11:41:30 CEST 2011
48 - change how Coro patches AnyEvent condvars for compatibility to
49 AnyEvent 6.x.
50 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
51 hasn't been included.
52
536.02 Wed Jul 13 04:35:19 CEST 2011
54 - "improve portability to Gentoo" - gentoo manages to put perl variables
55 in memory areas that are farther than 2gb apart, which the jit couldn't
56 handle and barfed. now it's just a bit slower on gentoo and similar
57 systems.
58
596.01 Sun Jul 3 12:31:14 CEST 2011
60 - workarounds are good, but the test for whether pthreads are used
61 was not good. thisone should be better.
62 - check differently whether gcc generates cfi instructions itself.

9 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 65 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
10 destroyed and cleaned up automatically (e.g. async { schedule }). 66 destroyed and cleaned up automatically (e.g. async { schedule }).
67 - implement a JIT compiler for part of the thread switch code,
68 which gives a 50% speed improvement on threaded perls, and
69 about 4% on non-thraeded perls (so threaded perls now finally
70 reach about half the speed of non-threaded perls).
71 - slightly modernise Coro::Intro, add section about rouse functions.
72 - avoid DEFSV and ERRSV, giving another 10% improvement
73 in thread switching.
11 - Coro::State->is_destroyed is now called is_zombie. 74 - Coro::State->is_destroyed is now called is_zombie.
12 - implement a Coro->safe_cancel method that might fail, but 75 - implement a Coro->safe_cancel method that might fail, but
13 cancels in a "safer" way if it succeeds. 76 cancels in a "safer" way if it succeeds.
77 - add preliminary support for DEBUGGING perls.
14 - get rid of two hash-accesses when initialising a new Coro - this 78 - get rid of two hash-accesses when initialising a new Coro - this
15 speeds up coro creation by almost a factor of two. 79 speeds up coro creation by almost a factor of two.
16 - croak when a coro that is being cancelled tries to block 80 - croak when a coro that is being cancelled tries to block
17 (e.g. while executing a guard block), instead of crashing or 81 (e.g. while executing a guard block), instead of crashing or
18 deadlocking. 82 deadlocking.

33 - get rid if coro refcounting - simply crash in other interpreter 97 - get rid if coro refcounting - simply crash in other interpreter
34 threads by nulling the pointers on clone. 98 threads by nulling the pointers on clone.

36 logic seems to be no longer neccessary. 100 logic seems to be no longer neccessary.
37 - use libecb instead of our own home-grown gcc hacks. 101 - use libecb instead of our own home-grown gcc hacks.
102 - document alternatives to Coro::LWP. Please use them :)
103 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
104 sigaltstack. Really. wine suffers from it, erlang suffers from it,
105 and it's known since at least 2006.

40 - apparently mingw doesn't provide a working gettimeofday, try to 108 - apparently mingw doesn't provide a working gettimeofday, try to
41 work around that by relying on Time::HiRes (indirectly brought to 109 work around that by relying on Time::HiRes (indirectly brought to
42 my attention by Max Maischein). 110 my attention by Max Maischein).
