9 | - INCOMPATIBLE CHANGE: unreferenced coro objects will now be |
|
|
10 | destroyed and cleaned up automatically (e.g. async { schedule }). |
|
|
11 | - implement a JIT compiler for part of the thread switch code, |
|
|
12 | which gives a 50% speed improvement on threaded perls, and |
|
|
13 | about 4% on non-thraeded perls (so threaded perls now finally |
|
|
14 | reach about half the speed of non-threaded perls). |
|
|
15 | - avoid DEFSV and ERRSV, giving another 10% improvement |
|
|
16 | in thread switching. |
|
|
17 | - Coro::State->is_destroyed is now called is_zombie. |
|
|
18 | - implement a Coro->safe_cancel method that might fail, but |
|
|
19 | cancels in a "safer" way if it succeeds. |
|
|
20 | - get rid of two hash-accesses when initialising a new Coro - this |
|
|
21 | speeds up coro creation by almost a factor of two. |
|
|
22 | - croak when a coro that is being cancelled tries to block |
|
|
23 | (e.g. while executing a guard block), instead of crashing or |
|
|
24 | deadlocking. |
|
|
25 | - use a more robust and also faster method to identify Coro::State |
|
|
26 | objects - speeds up everything a bit. |
|
|
27 | - implement Coro->cancel in XS for a 20% speed improvement, and to |
|
|
28 | be able to implement mutual cancellation. |
|
|
29 | - speed up context switches by a percent or two by more efficiently |
|
|
30 | allocating context stack entries. |
|
|
31 | - implement Coro->join and Coro->on_destroy in XS for a speedup and |
|
|
32 | a reduction in memory use. |
|
|
33 | - cancelling a coro while it itself is cancelling another coro is |
|
|
34 | now supported and working, instead of triggering an assertion. |
|
|
35 | - be a bit more crash-resistant when calling (buggy) on_destroy |
|
|
36 | callbacks (best effort). |
|
|
37 | - move on_destroy into the slf_frame, to allow extension slf |
|
|
38 | functions to have destructors. |
|
|
39 | - get rid if coro refcounting - simply crash in other interpreter |
|
|
40 | threads by nulling the pointers on clone. |
|
|
41 | - simplify warn/die hook handling when loading Coro - the convoluted |
|
|
42 | logic seems to be no longer neccessary. |
|
|
43 | - use libecb instead of our own home-grown gcc hacks. |
|
|

|
|
46 | - apparently mingw doesn't provide a working gettimeofday, try to |
|
|
47 | work around that by relying on Time::HiRes (indirectly brought to |
|
|
48 | my attention by Max Maischein). |
|
|
49 | - fix some portability issues when Time::HiRes was used. |
|
|
50 | |
|
|
51 | 5.371 Mon Feb 21 14:36:08 CET 2011 |
|
|
52 | - backport to windows process emulation code again. |
|
|
53 | |
|
|
54 | 5.37 Sat Feb 19 07:49:44 CET 2011 |
|
|
55 | - add a big "Coro thread life cycle" section to "man Coro". |
|
|
56 | - try a tentative workaround against the breakage that 5.13 has |
|
|
57 | introduced without depreciation period. sigh. |
|
|
58 | - no longer use Time::HiRes if gettimeofday is available, which |
|
|
59 | saves quite a lot of memory. |
|
|
60 | |
|
|
61 | 5.36 Sun Feb 13 05:33:41 CET 2011 |
|
|
62 | - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore, |
|
|
63 | Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new" |
|
|
64 | method call. |
|
|
65 | - undocument Coro::Timer::sleep and obsolete whole module. |
|
|
66 | - optimise Coro::Timer::timeout memory and cpu usage. |
|
|
67 | - slightly updated Coro::Intro for recent changes. |
|
|
68 | - do not initialise PL_dirty anymore. |
|
|
69 | |
|
|
70 | 5.25 Thu Nov 11 01:08:39 CET 2010 |
|
|
71 | - try a different approach on netbsd - netbsd 5 finally has marginally |
|
|
72 | working pthreads, but still broken ucontext/sigaltstack. |
|
|
73 | - openbsd 4.8 finally got their act together, Coro works out of the box |
|
|
74 | with asm, setjmp and pthreads (no change, just informational). |
