9 | - wrote a small introduction - Coro::Intro. |
10 | TODO: Coro::Signal as SLF. |
10 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
11 | - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). |
11 | - Coro::Select did errornously dup the file descriptors |
|
|
12 | and didn't work with all AnyEvent backends. |
|
|
13 | - disassociate c contexts from coro objects - this is agruably more |
|
|
14 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
15 | objects, for added memory savings and speed increases. |
|
|
16 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
17 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
18 | doesn't like this very much (and we *are* a type of entersub). |
|
|
19 | - implement state cloning, just to prove that call/cc can be done. |
|
|
20 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
21 | - better 5.8.6 compatibility. |
