85.0
9 - NEW ARCHITECTURE: use 4.912 for the stable version.
10 - bump API version to 7 - all dependents must be recompiled.
11 - directly patch the entersub opcode calling ssl functions (cede,
12 transfer and so on). this does speed up context switching by
13 up to 10%. More importanly, it frees us from the hardcoded
14 behaviour of entersub, so we might actually be able to return
15 something from those functions.
16 - take advanatge of __builtin_frame_address on gcc.
17 - expose THX in coroapi (not sure whether this was a wise decision).
18
194.912 Thu Nov 13 18:31:23 CET 2008
20 - minor cleanups.
21 - use much larger stacks on linux and perl < 5.8.8.
22 - Coro::Debug::new_unix_server did not unlink the socket
23 when destroyed.
24
254.911 Tue Nov 11 04:26:17 CET 2008
26 - "port" to threaded perls.
27
284.91 Mon Nov 10 05:36:38 CET 2008
29 - the ->throw exception object no longer leaks.
30 - creating a new cctx leaked a scopestack entry (memleak).
31 - new coroutines didn't get created with a zero flags field
32 (unknown impact).
33 - calling ->throw on a not-yet-started coroutine should now work
34 instead of being ignored.
35 - ->throw is now supported on Coro::State objects.
36 - clean up cctx creation code a bit.
37 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
38
394.9 Sat Nov 8 17:45:27 CET 2008
40 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
41 - (libcoro) no longer leak threads in the experimental pthread backend,
42 also speed it up considerably.
43 - (libcoro) do not rely on makecontext passing void *'s unscathed.
44 - fix compiletime dependencies on libcoro in the Makefile.
45 - cctx_count wasn't always updated properly.
46 - Coro::State::cctx_stacksize wasn't applied correctly.
47 - new function Coro::State::cctx_max_idle.
48 - the default max number of idle C contexts is now 4.
49 - (libcoro) try harder to get _setjmp/_longjmp.
50 - (libcoro) cleanup and extend the libcoro API to officially
51 allow the creation of empty source contexts.
52 - very experimental workaround for the totally broken netbsd platform.
53 - tried to hack around openbsd bugs.
54
554.804 Wed Nov 5 16:36:00 CET 2008
56 - Coro::Debug::new_unix_server would not create a non-blocking listening
57 socket, sometimes causing freezes.
58 - (libcoro) fix misaligned stack points for setjmp and assembly
59 methods, which can cause crashes on x86/x86_64 with a sufficiently
60 aggressive compiler.
61 - new function: Coro::Debug::new_tcp_server.
62 - move ->throw into the Coro class because it only works on coro objects.
63
644.803 Mon Nov 3 17:16:12 CET 2008
65 - (libcoro) use a global asm statement to become independent of gcc
66 otpimisations for CORO_ASM (thanks to pippijn for the idea).
67 - try to workaround yet another broken bsd, this time dragonfly.
68
694.802 Thu Oct 30 10:56:12 CET 2008
70 - support -fno-omit-frame-pointer on x86 with the assembly method.
71 - tune 01_unblock.t tests a bit.
72
734.801 Wed Oct 22 18:33:37 CEST 2008
74 - improve readline speed for very long "lines".
75 - backport to 5.8.8.
76
774.8 Thu Oct 2 13:34:40 CEST 2008
78 - new function Coro::AIO::aio_wait.
79 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
80 - greatly speed up and reduce memory usage of Coro::AIO requests.
81 - implement some other ยต-optimisations.
82
834.749 Mon Sep 29 14:40:12 CEST 2008
84 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
85
864.748 Sat Sep 27 14:03:19 CEST 2008
87 - implement, but do not document, PerlIO::cede(granularity).
88 - Coro::Storable forgot to wrap Storable::pstore.
89 - work around the multitude of leaks and memory corruption
90 bugs in PerlIO::via by using our own C-level perliol. As a side
91 effect, Coro::Storable is now much, much, much faster.
92
934.747 Tue Sep 23 01:59:41 CEST 2008
94 - fix a per-cv memleak (one empty array was leaked per
95 code reference).
96 - avoid a crash in coro->call|rss when the coroutine was already
97 destroyed (most noticably when using Coro::Debug::ps :)
98 - also protect *Storable::FILE.
99 - push up default storable granularity to 20ms.
100
1014.746 Sun Sep 21 03:22:20 CEST 2008
102 - be more insistent on locking Storable against reentrancy
103 in Coro::Storable.
104 - move swap_def?v and throw to Coro::State, as documented.
105
1064.745 Thu Jul 24 00:14:38 CEST 2008
107 - remove debugging code related to MgPV_nolen_const, also try to
108 make it compile with perl 5.8.6 (yes, apple apparently loves
109 outdated software). Reported by John S.
110
1114.744 Tue Jul 8 22:06:35 CEST 2008
112 - correctly provide default DIE/WARN handlers as documented.
113 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
114 implementations inside perl work fine for us.
115
1164.743 Mon Jun 16 00:21:57 CEST 2008
117 - when using Coro::EV without running EV::loop it could
118 result in busy-waiting for events, this has been fixed.
119 - reduce codesize and improve performance by using EV_DEFAULT_UC.
120
1214.742 Sat May 31 14:10:21 CEST 2008
122 - implement a workaround for (some) perl <5.8.8 versions.
123 - require EV 3.3+.
