26 | 5.1 Mon Nov 24 08:54:59 CET 2008 |
|
|
27 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
28 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
29 | - Coro::Select did errornously dup the file descriptors |
|
|
30 | and didn't work with all AnyEvent backends. |
|
|
31 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
32 | LWP data transfers. |
|
|
33 | - disassociate c contexts from coro objects - this is agruably more |
|
|
34 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
35 | objects, for added memory savings and speed increases. |
|
|
36 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
37 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
38 | doesn't like this very much (and we *are* a type of entersub). |
|
|
39 | - implement state cloning, just to prove that call/cc can be done. |
|
|
40 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
41 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
42 | do not have this method (and don't need it either). |
|
|
43 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
44 | callbacks. |
|
|
45 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
46 | others. It also makes the debugger happier, as you can trace |
|
|
47 | through the idle threads now. |
|
|
48 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
49 | - eg/event was pretty broken. |
|
|
50 | - better 5.8.6 compatibility. |

100 | making signals reliable for the first time. |
