13 | 5.1 Mon Nov 24 08:54:59 CET 2008 |
| 14 | - NEW ARCHITECTURE: use 4.912 for the stable version. |
14 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
15 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
16 | - Coro::Select did errornously dup the file descriptors |
|
|
17 | and didn't work with all AnyEvent backends. |
|
|
18 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
19 | LWP data transfers. |
|
|
20 | - disassociate c contexts from coro objects - this is agruably more |
|
|
21 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
22 | objects, for added memory savings and speed increases. |
|
|
23 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
24 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
25 | doesn't like this very much (and we *are* a type of entersub). |
|
|
26 | - implement state cloning, just to prove that call/cc can be done. |
|
|
27 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
28 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
29 | do not have this method (and don't need it either). |
|
|
30 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
31 | callbacks. |
|
|
32 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
33 | others. It also makes the debugger happier, as you can trace |
|
|
34 | through the idle threads now. |
|
|
35 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
36 | - eg/event was pretty broken. |
|
|
37 | - better 5.8.6 compatibility. |
|

|
|
40 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |
|
|
41 | stability issues. |

|
|
45 | and were annoying to support anyways :) |
|
|
46 | - removed SemaphoreSet's waiter method - use sem method instead. |

| 23 | - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). |
54 | - calling throw on a coroutine that is waiting for a semaphore will |
|
|
55 | no longer make it acquire the semaphore (and thus leak a count). |

|
|
58 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
59 | conversion of callback-style to blocking-style. |
|
|
60 | - new methods $coro->schedule_to and ->cede_to, to specifically |
|
|
61 | schedule or cede to a specific coroutine. |
|
|
62 | - new function Coro::Semaphore::wait. |
|
|

|
|
78 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
79 | four and reduce its memory usage considerably. |
|
|
80 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
81 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
82 | a new method "sem" to get at the underlying semaphore object. |
|
|
83 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
84 | (in comparison) 20-40% speedup. |
|
|
85 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
86 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
87 | making signals reliable for the first time. |
|
|
88 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
89 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
90 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
91 | a normal async is now very small. |
|
|
92 | - sped up coroutine creation/destruction by 40%. |

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