1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.

3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: destroy gets only called on cancel: fix(?) 4TODO: maybe implement a default message channel, very much like Erlang
5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).

9 - add Coro::Storable::blocking_thaw.
10 - use a vastly more complicated technique to localise
11 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
12 - use a coroutine for the idle callback Coro::Event,
13 instead of running Event in the current coroutine context.
14 This also catches recursive invocations.
15 - actually report fork errors in gethostbyname and inet_aton.

174.11 Thu Oct 11 02:40:24 CEST 2007
18 - port to threaded perls.
19
204.1 Thu Oct 11 02:38:16 CEST 2007
21 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
22 be local to each coro (see Coro::State).
23 - incompatible change: for very deep reasons, cede and cede_notself
24 cannot return anything, so nothing will be returned.
25 - possibly bring back 5.10 compatibility (untested).
26 - work around stupid (and wrong) warning on 5.10 :(.
27 - overlay the saved state over the context stack. This saves
28 a few hundred bytes per coroutine on average and also
29 speeds up context switching a bit.
30 - further tune default stack sizes.
31 - (more) correctly calculate stack usage in coro_rss.
32 - Coro::Storable::blocking_* did not properly lock
33 resulting in races between coroutines.
34 - added Coro::Storable::guard.
35 - stopping to trace a coroutine could destroy the cctx of
36 an unrelated coroutine.
37 - explain the relationship between Perl and C coroutines in
38 more detail in Coro::State.
39 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
40 causing a fork per resolve. This also affected Coro::Socket.
41 - switch to a separate stack in $coro->call/eval to avoid
42 invalidating pointers.
43
444.03 Sat Oct 6 21:24:00 CEST 2007
45 - added Coro::throw method.
46 - minor code cleanups.
47
484.02 Sat Oct 6 02:36:47 CEST 2007
49 - fix a very minor per-coroutine memleak (a single codereference).
50 - fixed a bug where the currently in-use c context would be freed
51 prematurely (can happen only when programs change the stacksize
52 or use tracing).
53 - tracing can no longer keep a coro alive after it terminated.
54 - do static branch prediction in the common path for gcc. gives
55 about 2-5% speed improvement here.
56
574.01 Fri Oct 5 22:10:49 CEST 2007
58 - instead of recreating *a* standard output handle we simply
59 use STDOUT, which is faster and hopefully more robust.
60
614.0 Fri Oct 5 12:56:00 CEST 2007
62 - incompatibly changed Coro::Storable::freeze.
63 - major new feature: added Coro::Debug, for interactive coroutine
64 debugging, tracing and much more.
65 - major bug fix: unbelievable, but true: $_, $/ and many other
66 "saved" variables actually weren't being saved. This has been fixed,
67 of course, while increasing performance while losing all the save
68 flags.
69 - save flags are gone, and all the api functions dealing with them.
70 - added Coro::Semaphore::adjust.
71 - added Coro::Util::fork_eval.
72 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
73 - added Coro::killall.
74 - reduce initial stack sizes to allow for "micro-coroutines".
75 - better async_pool resource management, moved parts of async_pool
76 handling to XS (major speed improvement).
77 - actually croak before modifying important data structures.
78 - refuse to transfer while compiling.
79 - possibly support eval EXPR better now.
80 - enable assembly per default on linux+bsd x86+amd64.
81 - all internal members were renamed _something for easier subclassing.
82 - many minor tweaks.
83
843.63 Wed May 16 14:10:06 CEST 2007
85 - implement handcoded assembly for x86/amd64 SVR ABI.
86
873.62 Fri Apr 27 21:36:06 CEST 2007
88 - upgrade libcoro (which might set unwind info correctly).
89 - change default on linux to setjmp/longjmp.
90
913.61 Thu Apr 19 12:36:18 CEST 2007
92 - Coro::Storable caused an endless loop when thawing invalid
93 pst's sometimes.
94 - use a Semaphore in Coro::Storable, as Storable doesn't
95 seem to be reentrant (although it is documented to
96 be threadsafe...).
97 - fix Coro::Signal to bring back the original unreliable
98 but stateful semantics.
99 - fixed a lot of typos in Coro.pm (patch submitted by David
100 Steinbrunner, which applied flawlessly).
101
1023.6 Sat Apr 14 17:13:31 CEST 2007
103 - added some bugfixes to get eg/myhttpd working again.
104 - added Coro::Storable for often-cede'ing freeze/thaw.
105 - try to do a clean exit when a coroutine calls exit
106 (EXPERIMENTAL).
107 - got rid of indirect call through _coro_init.
108 - updated the partly antique examples in eg/ to
109 work again and be a bit less magic, too.
110 - fixed Coro::Signal semantics to work as documented again.
111
1123.55 Sun Mar 25 01:20:47 CET 2007
7 - add SAVE_DEFFH to save the default filehandle and enable 113 - add SAVE_DEFFH to save the default filehandle and enable
8 it by default. 114 it by default.
9 - finally move socket-operations from Coro::Socket to Coro::Handle 115 - finally move socket-operations from Coro::Socket to Coro::Handle
10 to be able to unblock foreign sockets. 116 to be able to unblock foreign sockets.
11 - add Coro::State::save_also and guarded_save. 117 - add Coro::State::save_also and guarded_save.
