8 | 4.1 Thu Oct 11 02:38:16 CEST 2007 |
|
|
9 | - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now |
|
|
10 | be local to each coro (see Coro::State). |
|
|
11 | - incompatible change: for very deep reasons, cede and cede_notself |
|
|
12 | cannot return anything, so nothing will be returned. |
|
|
13 | - possibly bring back 5.10 compatibility (untested). |
|
|
14 | - work around stupid (and wrong) warning on 5.10 :(. |
|
|
15 | - overlay the saved state over the context stack. This saves |
|
|
16 | a few hundred bytes per coroutine on average and also |
|
|
17 | speeds up context switching a bit. |
|
|
18 | - further tune default stack sizes. |
|
|
19 | - (more) correctly calculate stack usage in coro_rss. |
|
|
20 | - Coro::Storable::blocking_* did not properly lock |
|
|
21 | resulting in races between coroutines. |
|
|
22 | - added Coro::Storable::guard. |
|
|
23 | - stopping to trace a coroutine could destroy the cctx of |
|
|
24 | an unrelated coroutine. |
|
|
25 | - explain the relationship between Perl and C coroutines in |
|
|
26 | more detail in Coro::State. |
|
|
27 | - Coro::Util::inet_aton did not short-circuit dotted quad forms, |
|
|
28 | causing a fork per resolve. This also affected Coro::Socket. |
|
|
29 | - switch to a separate stack in $coro->call/eval to avoid |
|
|
30 | invalidating pointers. |
|
|
31 | |
|
|
32 | 4.03 Sat Oct 6 21:24:00 CEST 2007 |
|
|
33 | - added Coro::throw method. |
|
|
34 | - minor code cleanups. |
|
|
35 | |
|
|
36 | 4.02 Sat Oct 6 02:36:47 CEST 2007 |
|
|
37 | - fix a very minor per-coroutine memleak (a single codereference). |
|
|
38 | - fixed a bug where the currently in-use c context would be freed |
|
|
39 | prematurely (can happen only when programs change the stacksize |
|
|
40 | or use tracing). |
|
|
41 | - tracing can no longer keep a coro alive after it terminated. |
|
|
42 | - do static branch prediction in the common path for gcc. gives |
|
|
43 | about 2-5% speed improvement here. |
|
|
44 | |
|
|
45 | 4.01 Fri Oct 5 22:10:49 CEST 2007 |
|
|
46 | - instead of recreating *a* standard output handle we simply |
|
|
47 | use STDOUT, which is faster and hopefully more robust. |
|
|
48 | |
|
|
49 | 4.0 Fri Oct 5 12:56:00 CEST 2007 |
|
|
50 | - incompatibly changed Coro::Storable::freeze. |
|
|
51 | - major new feature: added Coro::Debug, for interactive coroutine |
|
|
52 | debugging, tracing and much more. |
|
|
53 | - major bug fix: unbelievable, but true: $_, $/ and many other |
|
|
54 | "saved" variables actually weren't being saved. This has been fixed, |
|
|
55 | of course, while increasing performance while losing all the save |
|
|
56 | flags. |
|
|
57 | - save flags are gone, and all the api functions dealing with them. |
|
|
58 | - added Coro::Semaphore::adjust. |
|
|
59 | - added Coro::Util::fork_eval. |
|
|
60 | - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. |
|
|
61 | - added Coro::killall. |
|
|
62 | - reduce initial stack sizes to allow for "micro-coroutines". |
|
|
63 | - better async_pool resource management, moved parts of async_pool |
|
|
64 | handling to XS (major speed improvement). |
|
|
65 | - actually croak before modifying important data structures. |
|
|
66 | - refuse to transfer while compiling. |
|
|
67 | - possibly support eval EXPR better now. |
|
|
68 | - enable assembly per default on linux+bsd x86+amd64. |
|
|
69 | - all internal members were renamed _something for easier subclassing. |
|
|
70 | - many minor tweaks. |
|
|
71 | |
|
|
72 | 3.63 Wed May 16 14:10:06 CEST 2007 |
|
|
73 | - implement handcoded assembly for x86/amd64 SVR ABI. |
|
|
74 | |
|
|
75 | 3.62 Fri Apr 27 21:36:06 CEST 2007 |
