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: destroy gets only called on cancel: fix(?)
4TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
5TODO: maybe implement a default message channel, very much like Erlang
6 (which is cool in a lot of important aspects (failures!),
7 but very lacking in others).
4 8
5TODO: eg/lwp to use Coro::Select 93.8
6 - should compile with perl 5.9.x now. 10 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more.
13 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool
18 handling to XS (major speed improvement).
19 - actually croak before modifying important data structures.
20 - refuse to transfer while compiling.
21 - possibly support eval EXPR better now.
22 - many minor tweaks.
23
243.63 Wed May 16 14:10:06 CEST 2007
25 - implement handcoded assembly for x86/amd64 SVR ABI.
26
273.62 Fri Apr 27 21:36:06 CEST 2007
28 - upgrade libcoro (which might set unwind info correctly).
29 - change default on linux to setjmp/longjmp.
30
313.61 Thu Apr 19 12:36:18 CEST 2007
32 - Coro::Storable caused an endless loop when thawing invalid
33 pst's sometimes.
34 - use a Semaphore in Coro::Storable, as Storable doesn't
35 seem to be reentrant (although it is documented to
36 be threadsafe...).
37 - fix Coro::Signal to bring back the original unreliable
38 but stateful semantics.
39 - fixed a lot of typos in Coro.pm (patch submitted by David
40 Steinbrunner, which applied flawlessly).
41
423.6 Sat Apr 14 17:13:31 CEST 2007
43 - added some bugfixes to get eg/myhttpd working again.
44 - added Coro::Storable for often-cede'ing freeze/thaw.
45 - try to do a clean exit when a coroutine calls exit
46 (EXPERIMENTAL).
47 - got rid of indirect call through _coro_init.
48 - updated the partly antique examples in eg/ to
49 work again and be a bit less magic, too.
50 - fixed Coro::Signal semantics to work as documented again.
51
523.55 Sun Mar 25 01:20:47 CET 2007
53 - add SAVE_DEFFH to save the default filehandle and enable
54 it by default.
55 - finally move socket-operations from Coro::Socket to Coro::Handle
56 to be able to unblock foreign sockets.
57 - add Coro::State::save_also and guarded_save.
58 - add count accessor to Coro::Semaphore.
59 - add Coro::State::cctx_stacksize.
60 - just for the fun of it, do not rely on implicit context,
61 which can dramatically improve performance, but people
62 using windows-process-emulation perls do not care much about
63 performance.
64
653.51 Sun Mar 4 14:18:04 CET 2007
66 - fixed a problem when you weakened references to Coro::State's
67 (patch by Yuval Kogman).
68
693.501 Wed Feb 28 12:44:07 CET 2007
70 - rename some global symbols as macosx from hell redefines
71 them without asking.
72
733.5 Tue Feb 13 20:22:53 CET 2007
74 - do AnyEvent model detection earlier, avoiding problems
75 caused by first using AnyEvent and later Coro::Event.
76 - implement and document Coro::Event event objects.
77 - fix a potential problem in Coro::Event causing crashes.
78 - initialise PL_comppad when creating a new coroutine,
79 avoids crashes on early coro destruction.
80
813.41 Mon Jan 22 19:19:49 CET 2007
82 - readline on Coro::Handle did not support undefined $/,
83 nor did it deliver partial lines on EOF or error.
84 - implement malloc fallback for stack allocation because
85 stupid broken idiotic OSX has a stupid broken
86 idiotic fits-the-whole-os mmap "implementation" and
87 my dick feels longer if Coro is portable even to
88 obsolete platforms.
89
903.4 Fri Jan 19 21:52:54 CET 2007
91 - remove t/09_timer.t, as it isn't really testing much
92 but was rather flaky in practise.
93 - async_pool coro would keep arguments and callback alive until
94 it was reused.
95 - cancellation of a coroutine could cause spurious idle calls
96 in cede_notself.
97
983.3 Sat Jan 6 03:45:00 CET 2007
99 - implement $coro->on_destroy.
100 - Coro::Event blocking semantics have been changed,
101 documented and - hopefully - improved.
102 - fix nice adding, not subtracting, from priority.
103 - fix ->prio and api_is_ready (patch by Mark Hinds).
104 - fixed an assert ("... == prev__cctx->idle_te")
105 that could errronously trigger.
106 - fix various large and small memleaks.
107 - use a (hopefully) more stable cancel implementation
108 that immediately frees the coroutine data.
109 - cede/cede_notself return a status now.
110 - added Coro::guard function.
111 - added a global coroutine pool for jobs (on my machine,
112 I can create and execute 48k simple coros/s with async,
113 and 128k coros with async_pool).
114 - Coro::AIO now uses the coroutine priority as io priority.
115
1163.2 Fri Dec 22 05:07:09 CET 2006
117 - improve portability to slightly older perls.
118 - use cleaner coroutine destruction.
119 - simplify configuration for users.
120 - optionally (unrecommended) prefer perl functions over
121 their coro replacements.
122
1233.11 Tue Dec 5 13:11:24 CET 2006
124 - fixed some bogus assert's, but as perl.h disables assert even
125 without NDEBUG (thank you very much), not too many people should
126 notice (that did include myself). Andreas König noticed, though :)
127 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
128 it. Also noticed by Andreas König :)
129 - save/restore tainted status.
130 - verified to pass the testsuite on my 5.9.5.
131
1323.1 Mon Dec 4 23:03:40 CET 2006
133 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
134 - incompatible change: transfer flags are now per-state.
135 - give a better error message on deadlock.
136 - document Coro::nready.
137 - enhanced testsuite.
138
1393.01 Sun Dec 3 23:47:42 CET 2006
140 - forgot to include Coro::Timer.
141
1423.0 Sun Dec 3 22:57:25 CET 2006
143 - the "FINALLY COMPLETELY STABLE" release (coming soon:
144 the "FAMOUS LAST WORDS" release).
145 - implement a new stack sharing algorithm, which uses a stack
146 pool (size currently hardcoded).
147 - make stack sharing mandatory (it no longer uses a heuristic).
148 - eval/die no longer cause weird problems under heavy use.
149 - Coro::Event could cause livelocks if it was used but
150 no Coro::Event watchers were used.
151 - Coro::Event now uses asynccheck as prepare does not
152 check for changed watchers.
153 - Coro::Event allows multiple waiting coros and will wake up one
154 per event.
155 - Coro::Event should be cleaner and more efficient now.
156 - new utility function Coro::unblock_sub.
157 - document the sad fact that Event is no longer reentrant.
158 - putting a coroutine into the ready queue twice could under
159 some circumstances lead to stack corruption.
160 - minor incompatibility: subclassing Coro::State is supported
161 directly now without going through a _coro_state member.
162 - state/coro switching is much faster now.
163 - very minor optimisations and code/documentation cleanup.
164 - avoid problems due to compiler inlining.
165 - removed timers from Coro::Timer -> use AnyEvent instead.
166 - replaced Coro::idle coroutine by (cleaner) idle handler.
167 - updated to newest libcoro.
168 - implement enhanced support for valgrind.
169 - implement is_ready and return value for ready.
170 - removed Coro::Cont, it was a misnomer (it's generators),
171 and it was somewhat annoying to get it right. Will come back
172 if somebody asks for it :)
173 - many ->wait methods and Coro::Event could return
174 spuriously without the event having happened.
175
1762.5 Tue Nov 7 12:22:33 CET 2006
177 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
178 use AnyEvent, moved them to Coro/.
179 - added Coro::LWP which contains all the uglyness required to
180 make LWP non-blocking.
181 - should work with perl 5.9.x now (Andreas König made me do it).
182 - fixed another bug in Coro::Select when the timeout was undef.
7 - reuse PL_start_env for all coros, saves some memory per coroutine. 183 - reuse PL_start_env for all coros, saves some memory per coroutine.
8 - manage PL_top_env differently, hopefully to avoid panic: top_env. 184 - manage PL_top_env differently, hopefully to avoid panic: top_env.
9 - timeout argument was not properly used in Coro::Socket. 185 - timeout argument was not properly used in Coro::Socket.
10 - allow limited forms of subclassing in Coro::Handle/Coro::Socket. 186 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
11 - made Coro::Util an AnyEvent user, moved it to Coro/. 187 - emulate undocumented(!) functionality of IO::Socket required
188 by LWP(!!).
189 - updated eg/lwp to work with newer lwp's.
12 - remove "FATAL: uncaught exception" prefix. coroutines that die 190 - remove "FATAL: uncaught exception" prefix. Coroutines that die
13 kill the whole process, just as exceptions in the main coroutine 191 kill the whole process, just as exceptions in the main "coroutine"
14 do. 192 did already.

162.1 Wed Nov 1 23:01:13 CET 2006 1942.1 Wed Nov 1 23:01:13 CET 2006
17 - fix a long-standing bug in Coro::Select where select with 195 - fix a long-standing bug in Coro::Select where select with
18 zero timeout would instead change the current default filehandle. 196 zero timeout would instead change the current default filehandle.
19 - use a simpler and hopefully more robust way to clone padlists 197 - use a simpler and hopefully more robust way to clone padlists
