1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: possibly convert some of the Event modules into AnyEvent users. 3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
6TODO: maybe implement a default message channel, very much like Erlang
7 (which is cool in a lot of important aspects (failures!),
8 but very lacking in others).
4 9
5TODO: eg/lwp to use Coro::Select 103.7
6TODO: Event/LWP.pm 11 - incompatibly changed Coro::Storable::freeze.
7 - should compile with perl 5.9.x now. 12 - added Coro::Debug, interactive coroutine debugging and much
13 more.
14 - added Coro::Semaphore::adjust.
15 - added Coro::Util::fork_eval.
16 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
17 - reduce initial stack sizes to allow for "micro-coroutines".
18 - better async_pool resource management, moved parts of async_pool
19 handling to XS (major speed improvement).
20 - many minor tweaks.
21
223.63 Wed May 16 14:10:06 CEST 2007
23 - implement handcoded assembly for x86/amd64 SVR ABI.
24
253.62 Fri Apr 27 21:36:06 CEST 2007
26 - upgrade libcoro (which might set unwind info correctly).
27 - change default on linux to setjmp/longjmp.
28
293.61 Thu Apr 19 12:36:18 CEST 2007
30 - Coro::Storable caused an endless loop when thawing invalid
31 pst's sometimes.
32 - use a Semaphore in Coro::Storable, as Storable doesn't
33 seem to be reentrant (although it is documented to
34 be threadsafe...).
35 - fix Coro::Signal to bring back the original unreliable
36 but stateful semantics.
37 - fixed a lot of typos in Coro.pm (patch submitted by David
38 Steinbrunner, which applied flawlessly).
39
403.6 Sat Apr 14 17:13:31 CEST 2007
41 - added some bugfixes to get eg/myhttpd working again.
42 - added Coro::Storable for often-cede'ing freeze/thaw.
43 - try to do a clean exit when a coroutine calls exit
44 (EXPERIMENTAL).
45 - got rid of indirect call through _coro_init.
46 - updated the partly antique examples in eg/ to
47 work again and be a bit less magic, too.
48 - fixed Coro::Signal semantics to work as documented again.
49
503.55 Sun Mar 25 01:20:47 CET 2007
51 - add SAVE_DEFFH to save the default filehandle and enable
52 it by default.
53 - finally move socket-operations from Coro::Socket to Coro::Handle
54 to be able to unblock foreign sockets.
55 - add Coro::State::save_also and guarded_save.
56 - add count accessor to Coro::Semaphore.
57 - add Coro::State::cctx_stacksize.
58 - just for the fun of it, do not rely on implicit context,
59 which can dramatically improve performance, but people
60 using windows-process-emulation perls do not care much about
61 performance.
62
633.51 Sun Mar 4 14:18:04 CET 2007
64 - fixed a problem when you weakened references to Coro::State's
65 (patch by Yuval Kogman).
66
673.501 Wed Feb 28 12:44:07 CET 2007
68 - rename some global symbols as macosx from hell redefines
69 them without asking.
70
713.5 Tue Feb 13 20:22:53 CET 2007
72 - do AnyEvent model detection earlier, avoiding problems
73 caused by first using AnyEvent and later Coro::Event.
74 - implement and document Coro::Event event objects.
75 - fix a potential problem in Coro::Event causing crashes.
76 - initialise PL_comppad when creating a new coroutine,
77 avoids crashes on early coro destruction.
78
793.41 Mon Jan 22 19:19:49 CET 2007
80 - readline on Coro::Handle did not support undefined $/,
81 nor did it deliver partial lines on EOF or error.
82 - implement malloc fallback for stack allocation because
83 stupid broken idiotic OSX has a stupid broken
84 idiotic fits-the-whole-os mmap "implementation" and
85 my dick feels longer if Coro is portable even to
86 obsolete platforms.
87
883.4 Fri Jan 19 21:52:54 CET 2007
89 - remove t/09_timer.t, as it isn't really testing much
90 but was rather flaky in practise.
91 - async_pool coro would keep arguments and callback alive until
92 it was reused.
93 - cancellation of a coroutine could cause spurious idle calls
94 in cede_notself.
95
963.3 Sat Jan 6 03:45:00 CET 2007
97 - implement $coro->on_destroy.
98 - Coro::Event blocking semantics have been changed,
99 documented and - hopefully - improved.
100 - fix nice adding, not subtracting, from priority.
101 - fix ->prio and api_is_ready (patch by Mark Hinds).
102 - fixed an assert ("... == prev__cctx->idle_te")
103 that could errronously trigger.
104 - fix various large and small memleaks.
105 - use a (hopefully) more stable cancel implementation
106 that immediately frees the coroutine data.
107 - cede/cede_notself return a status now.
108 - added Coro::guard function.
109 - added a global coroutine pool for jobs (on my machine,
110 I can create and execute 48k simple coros/s with async,
111 and 128k coros with async_pool).
112 - Coro::AIO now uses the coroutine priority as io priority.
113
1143.2 Fri Dec 22 05:07:09 CET 2006
115 - improve portability to slightly older perls.
116 - use cleaner coroutine destruction.
117 - simplify configuration for users.
118 - optionally (unrecommended) prefer perl functions over
119 their coro replacements.
120
1213.11 Tue Dec 5 13:11:24 CET 2006
122 - fixed some bogus assert's, but as perl.h disables assert even
123 without NDEBUG (thank you very much), not too many people should
124 notice (that did include myself). Andreas König noticed, though :)
125 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
126 it. Also noticed by Andreas König :)
127 - save/restore tainted status.
128 - verified to pass the testsuite on my 5.9.5.
129
1303.1 Mon Dec 4 23:03:40 CET 2006
131 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
132 - incompatible change: transfer flags are now per-state.
133 - give a better error message on deadlock.
134 - document Coro::nready.
135 - enhanced testsuite.
136
1373.01 Sun Dec 3 23:47:42 CET 2006
138 - forgot to include Coro::Timer.
139
1403.0 Sun Dec 3 22:57:25 CET 2006
141 - the "FINALLY COMPLETELY STABLE" release (coming soon:
142 the "FAMOUS LAST WORDS" release).
143 - implement a new stack sharing algorithm, which uses a stack
144 pool (size currently hardcoded).
145 - make stack sharing mandatory (it no longer uses a heuristic).
146 - eval/die no longer cause weird problems under heavy use.
147 - Coro::Event could cause livelocks if it was used but
148 no Coro::Event watchers were used.
149 - Coro::Event now uses asynccheck as prepare does not
150 check for changed watchers.
151 - Coro::Event allows multiple waiting coros and will wake up one
152 per event.
153 - Coro::Event should be cleaner and more efficient now.
154 - new utility function Coro::unblock_sub.
155 - document the sad fact that Event is no longer reentrant.
156 - putting a coroutine into the ready queue twice could under
157 some circumstances lead to stack corruption.
158 - minor incompatibility: subclassing Coro::State is supported
159 directly now without going through a _coro_state member.
160 - state/coro switching is much faster now.
161 - very minor optimisations and code/documentation cleanup.
162 - avoid problems due to compiler inlining.
163 - removed timers from Coro::Timer -> use AnyEvent instead.
164 - replaced Coro::idle coroutine by (cleaner) idle handler.
165 - updated to newest libcoro.
166 - implement enhanced support for valgrind.
167 - implement is_ready and return value for ready.
168 - removed Coro::Cont, it was a misnomer (it's generators),
169 and it was somewhat annoying to get it right. Will come back
170 if somebody asks for it :)
171 - many ->wait methods and Coro::Event could return
172 spuriously without the event having happened.
173
1742.5 Tue Nov 7 12:22:33 CET 2006
175 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
176 use AnyEvent, moved them to Coro/.
177 - added Coro::LWP which contains all the uglyness required to
178 make LWP non-blocking.
179 - should work with perl 5.9.x now (Andreas König made me do it).
180 - fixed another bug in Coro::Select when the timeout was undef.
8 - reuse PL_start_env for all coros, saves some memory per coroutine. 181 - reuse PL_start_env for all coros, saves some memory per coroutine.
9 - manage PL_top_env differently, hopefully to avoid panic: top_env. 182 - manage PL_top_env differently, hopefully to avoid panic: top_env.
10 - timeout argument was not properly used in Coro::Socket. 183 - timeout argument was not properly used in Coro::Socket.
11 - allow limited forms of subclassing in Coro::Handle/Coro::Socket. 184 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
12 - emulate undocumented(!) functionality of IO::Socket required 185 - emulate undocumented(!) functionality of IO::Socket required
13 by LWP(!!). 186 by LWP(!!).
14 - updated eg/lwp to work with newer lwp's. 187 - updated eg/lwp to work with newer lwp's.
15 - made Coro::Util an AnyEvent user, moved it to Coro/.
16 - remove "FATAL: uncaught exception" prefix. coroutines that die 188 - remove "FATAL: uncaught exception" prefix. Coroutines that die
17 kill the whole process, just as exceptions in the main coroutine 189 kill the whole process, just as exceptions in the main "coroutine"
18 do. 190 did already.

21 - fix a long-standing bug in Coro::Select where select with 193 - fix a long-standing bug in Coro::Select where select with
22 zero timeout would instead change the current default filehandle. 194 zero timeout would instead change the current default filehandle.
23 - use a simpler and hopefully more robust way to clone padlists 195 - use a simpler and hopefully more robust way to clone padlists
