11 | 5.0 |
13 | 5.132 Fri May 29 09:00:39 CEST 2009 |
12 | - NEW ARCHITECTURE: use 4.912 for the stable version. |
14 | - do not keep a reference to the argument itself in |
|
|
15 | Coro::Semaphore::guard, as it could change later. |
|
|
16 | - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options, |
|
|
17 | should support a prepare callback. |
|
|
18 | |
|
|
19 | 5.131 Mon Mar 16 23:20:37 CET 2009 |
|
|
20 | - implement and document Coro->suspend, Coro->resume. |
|
|
21 | - fix Coro::Select implementation to not (often) close |
|
|
22 | the passed file descriptors (testcase provided by pippijn). |
|
|
23 | |
|
|
24 | 5.13 Mon Dec 15 21:51:42 CET 2008 |
|
|
25 | - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave). |
|
|
26 | - don't set diehook to C<undef> but instead to NULL, to avoid |
|
|
27 | spurious warnings. |
|
|
28 | - fix a lot of bugs in Coro::SemaphoreSet. |
|
|
29 | - Coro::SemaphoreSet will less often create a semaphore needlessly. |
|
|
30 | - add Coro::SemaphoreSet::count and wait methods. |
|
|
31 | - take advantage of the new Guard module. |
|
|
32 | - deprecate Coro::guard. |
|
|
33 | - try to fix the dreaded 01_unblock tests once more. I hate it when |
|
|
34 | testsuites need more fixing than the code they are supposed to test. |
|
|
35 | - croak in more cases when a required callback isn't resolvable. |
|
|
36 | - fix some minor issues in Coro::State->call/eval. |
|
|
37 | - use current coroutine context instead of a temporary one |
|
|
38 | when temporarily switching to another coroutine. |
|
|
39 | - do not call C-level on_destroy handlers during global destruction, |
|
|
40 | to avoid needless segfaults. |
|
|
41 | |
|
|
42 | 5.12 Sun Dec 7 13:30:38 CET 2008 |
|
|
43 | - add default config for MirOS, which seems to be a bug-to-bug |
|
|
44 | compatible fork of openbsd ("world domination by releasing |
|
|
45 | openbsd cvs before the openbsd folks do it" or so :). |
|
|
46 | - free_padlist did destroy the names pad, not good, but didn't |
|
|
47 | seem to bother perl - this could fix issues such as eval "" |
|
|
48 | inside a function called from multiple coroutines. |
|
|
49 | - use a different method to detect destruction time. |
|
|
50 | - be more careful when freeing padlists just before global |
|
|
51 | destruction. |
|
|
52 | - fixed and expanded the call/cc example. |
|
|
53 | - renamed _terminate to _coro_run. |
|
|
54 | - new method Coro::Channel->shutdown. |
|
|
55 | - try pthreads on openbsd <4.4 (broken sigaltstack, will |
|
|
56 | pthreads fare better?). |
|
|
57 | - be less picky about destroying "a" running coroutine. |
|
|
58 | |
|
|
59 | 5.11 Tue Nov 25 21:49:05 CET 2008 |
|
|
60 | - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly |
|
|
61 | working code with failed assertions, introducing more bugs than |
|
|
62 | it fixes, requiring elaborate workarounds :( |
|
|
63 | |
|
|
64 | 5.1 Mon Nov 24 08:54:59 CET 2008 |
|
|
65 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
66 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
67 | - Coro::Select did errornously dup the file descriptors |
|
|
68 | and didn't work with all AnyEvent backends. |
|
|
69 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
70 | LWP data transfers. |
|
|
71 | - disassociate c contexts from coro objects - this is agruably more |
|
|
72 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
73 | objects, for added memory savings and speed increases. |
|
|
74 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
75 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
76 | doesn't like this very much (and we *are* a type of entersub). |
|
|
77 | - implement state cloning, just to prove that call/cc can be done. |
|
|
78 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
79 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
80 | do not have this method (and don't need it either). |
|
|
81 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
82 | callbacks. |
|
|
83 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
84 | others. It also makes the debugger happier, as you can trace |
|
|
85 | through the idle threads now. |
|
|
86 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
87 | - eg/event was pretty broken. |
|
|
88 | - better 5.8.6 compatibility. |
|
|
89 | |
|
|
90 | 5.0 Thu Nov 20 10:35:05 CET 2008 |
|

91 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |

|
109 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
110 | conversion of callback-style to blocking-style. |
|
|
111 | - new methods $coro->schedule_to and ->cede_to, to specifically |
|
|
112 | schedule or cede to a specific coroutine. |
|
|
113 | - new function Coro::Semaphore::wait. |
|

128 | factor of three. |
|
|
129 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
130 | four and reduce its memory usage considerably. |
|
|
131 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
132 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
133 | a new method "sem" to get at the underlying semaphore object. |
|
|
134 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
135 | (in comparison) 20-40% speedup. |
|
|
136 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
137 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
138 | making signals reliable for the first time. |
|
|
139 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
140 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
141 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
142 | a normal async is now very small. |
|
|
143 | - sped up coroutine creation/destruction by 40%. |
40 | - forgot to include Coro/libcoro/README in the dist for all these years. |

|
147 | - use new rouse functions to speed up and simplify Coro::BDB. |
|
|
148 | - make "prefer perl native functions" work with threaded perls. |
|
|
149 | - condense Coro::Debug ps output, hint at v and w flags. |
|
|
150 | - (libcoro) lots of minor cleanups and portability improvements. |
