1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
33.0 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
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)).
7
84.1
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State).
11 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit.
16 - further tune default stack sizes.
17 - (more) correctly calculate stack usage in coro_rss.
18 - Coro::Storable::blocking_* did not properly lock
19 resulting in races between coroutines.
20 - added Coro::Storable::guard.
21
224.03 Sat Oct 6 21:24:00 CEST 2007
23 - added Coro::throw method.
24 - minor code cleanups.
25
264.02 Sat Oct 6 02:36:47 CEST 2007
27 - fix a very minor per-coroutine memleak (a single codereference).
28 - fixed a bug where the currently in-use c context would be freed
29 prematurely (can happen only when programs change the stacksize
30 or use tracing).
31 - tracing can no longer keep a coro alive after it terminated.
32 - do static branch prediction in the common path for gcc. gives
33 about 2-5% speed improvement here.
34
354.01 Fri Oct 5 22:10:49 CEST 2007
36 - instead of recreating *a* standard output handle we simply
37 use STDOUT, which is faster and hopefully more robust.
38
394.0 Fri Oct 5 12:56:00 CEST 2007
40 - incompatibly changed Coro::Storable::freeze.
41 - major new feature: added Coro::Debug, for interactive coroutine
42 debugging, tracing and much more.
43 - major bug fix: unbelievable, but true: $_, $/ and many other
44 "saved" variables actually weren't being saved. This has been fixed,
45 of course, while increasing performance while losing all the save
46 flags.
47 - save flags are gone, and all the api functions dealing with them.
48 - added Coro::Semaphore::adjust.
49 - added Coro::Util::fork_eval.
50 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
51 - added Coro::killall.
52 - reduce initial stack sizes to allow for "micro-coroutines".
53 - better async_pool resource management, moved parts of async_pool
54 handling to XS (major speed improvement).
55 - actually croak before modifying important data structures.
56 - refuse to transfer while compiling.
57 - possibly support eval EXPR better now.
58 - enable assembly per default on linux+bsd x86+amd64.
59 - all internal members were renamed _something for easier subclassing.
60 - many minor tweaks.
61
623.63 Wed May 16 14:10:06 CEST 2007
63 - implement handcoded assembly for x86/amd64 SVR ABI.
64
653.62 Fri Apr 27 21:36:06 CEST 2007
66 - upgrade libcoro (which might set unwind info correctly).
67 - change default on linux to setjmp/longjmp.
68
693.61 Thu Apr 19 12:36:18 CEST 2007
70 - Coro::Storable caused an endless loop when thawing invalid
71 pst's sometimes.
72 - use a Semaphore in Coro::Storable, as Storable doesn't
73 seem to be reentrant (although it is documented to
74 be threadsafe...).
75 - fix Coro::Signal to bring back the original unreliable
76 but stateful semantics.
77 - fixed a lot of typos in Coro.pm (patch submitted by David
78 Steinbrunner, which applied flawlessly).
79
803.6 Sat Apr 14 17:13:31 CEST 2007
81 - added some bugfixes to get eg/myhttpd working again.
82 - added Coro::Storable for often-cede'ing freeze/thaw.
83 - try to do a clean exit when a coroutine calls exit
84 (EXPERIMENTAL).
85 - got rid of indirect call through _coro_init.
86 - updated the partly antique examples in eg/ to
87 work again and be a bit less magic, too.
88 - fixed Coro::Signal semantics to work as documented again.
89
903.55 Sun Mar 25 01:20:47 CET 2007
91 - add SAVE_DEFFH to save the default filehandle and enable
92 it by default.
93 - finally move socket-operations from Coro::Socket to Coro::Handle
94 to be able to unblock foreign sockets.
95 - add Coro::State::save_also and guarded_save.
96 - add count accessor to Coro::Semaphore.
97 - add Coro::State::cctx_stacksize.
98 - just for the fun of it, do not rely on implicit context,
99 which can dramatically improve performance, but people
100 using windows-process-emulation perls do not care much about
101 performance.
102
1033.51 Sun Mar 4 14:18:04 CET 2007
104 - fixed a problem when you weakened references to Coro::State's
105 (patch by Yuval Kogman).
106
1073.501 Wed Feb 28 12:44:07 CET 2007
108 - rename some global symbols as macosx from hell redefines
109 them without asking.
110
1113.5 Tue Feb 13 20:22:53 CET 2007
112 - do AnyEvent model detection earlier, avoiding problems
113 caused by first using AnyEvent and later Coro::Event.
114 - implement and document Coro::Event event objects.
115 - fix a potential problem in Coro::Event causing crashes.
116 - initialise PL_comppad when creating a new coroutine,
117 avoids crashes on early coro destruction.
118
1193.41 Mon Jan 22 19:19:49 CET 2007
120 - readline on Coro::Handle did not support undefined $/,
121 nor did it deliver partial lines on EOF or error.
122 - implement malloc fallback for stack allocation because
123 stupid broken idiotic OSX has a stupid broken
124 idiotic fits-the-whole-os mmap "implementation" and
125 my dick feels longer if Coro is portable even to
126 obsolete platforms.
127
1283.4 Fri Jan 19 21:52:54 CET 2007
129 - remove t/09_timer.t, as it isn't really testing much
130 but was rather flaky in practise.
131 - async_pool coro would keep arguments and callback alive until
132 it was reused.
133 - cancellation of a coroutine could cause spurious idle calls
134 in cede_notself.
135
1363.3 Sat Jan 6 03:45:00 CET 2007
137 - implement $coro->on_destroy.
138 - Coro::Event blocking semantics have been changed,
139 documented and - hopefully - improved.
140 - fix nice adding, not subtracting, from priority.
141 - fix ->prio and api_is_ready (patch by Mark Hinds).
142 - fixed an assert ("... == prev__cctx->idle_te")
143 that could errronously trigger.
144 - fix various large and small memleaks.
145 - use a (hopefully) more stable cancel implementation
146 that immediately frees the coroutine data.
147 - cede/cede_notself return a status now.
148 - added Coro::guard function.
149 - added a global coroutine pool for jobs (on my machine,
150 I can create and execute 48k simple coros/s with async,
151 and 128k coros with async_pool).
152 - Coro::AIO now uses the coroutine priority as io priority.
153
1543.2 Fri Dec 22 05:07:09 CET 2006
155 - improve portability to slightly older perls.
156 - use cleaner coroutine destruction.
157 - simplify configuration for users.
158 - optionally (unrecommended) prefer perl functions over
159 their coro replacements.
160
1613.11 Tue Dec 5 13:11:24 CET 2006
162 - fixed some bogus assert's, but as perl.h disables assert even
163 without NDEBUG (thank you very much), not too many people should
164 notice (that did include myself). Andreas König noticed, though :)
165 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
166 it. Also noticed by Andreas König :)
167 - save/restore tainted status.
168 - verified to pass the testsuite on my 5.9.5.
169
1703.1 Mon Dec 4 23:03:40 CET 2006
171 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
172 - incompatible change: transfer flags are now per-state.
173 - give a better error message on deadlock.
174 - document Coro::nready.
175 - enhanced testsuite.
176
1773.01 Sun Dec 3 23:47:42 CET 2006
178 - forgot to include Coro::Timer.
179
1803.0 Sun Dec 3 22:57:25 CET 2006
181 - the "FINALLY COMPLETELY STABLE" release (coming soon:
182 the "FAMOUS LAST WORDS" release).
4 - reimplement a new stack sharing algorithm. 183 - implement a new stack sharing algorithm, which uses a stack
184 pool (size currently hardcoded).
5 - make stack sharing mandatory (it no longer uses a heuristic). 185 - make stack sharing mandatory (it no longer uses a heuristic).
6 - eval/die no longer cause weird problems under heavy use. 186 - eval/die no longer cause weird problems under heavy use.
7 - Coro::Event could cause livelocks if it was used but 187 - Coro::Event could cause livelocks if it was used but
8 no Coro::Event watchers were used. 188 no Coro::Event watchers were used.
189 - Coro::Event now uses asynccheck as prepare does not
190 check for changed watchers.
191 - Coro::Event allows multiple waiting coros and will wake up one
192 per event.
9 - Coro::Event should be cleaner and more efficient now. 193 - Coro::Event should be cleaner and more efficient now.
194 - new utility function Coro::unblock_sub.
195 - document the sad fact that Event is no longer reentrant.
196 - putting a coroutine into the ready queue twice could under
197 some circumstances lead to stack corruption.
10 - minor incompatibility: subclassing Coro::State is supported 198 - minor incompatibility: subclassing Coro::State is supported
11 directly now without going through a _coro_state member. 199 directly now without going through a _coro_state member.
12 - state/coro switching is much faster now. 200 - state/coro switching is much faster now.
13 - very minor optimisations and code/documentation cleanup. 201 - very minor optimisations and code/documentation cleanup.
14 - avoid problems due to compiler inlining. 202 - avoid problems due to compiler inlining.
15 - removed timers from Coro::Timer -> use AnyEvent instead. 203 - removed timers from Coro::Timer -> use AnyEvent instead.

18 - implement enhanced support for valgrind. 206 - implement enhanced support for valgrind.
207 - implement is_ready and return value for ready.
208 - removed Coro::Cont, it was a misnomer (it's generators),
209 and it was somewhat annoying to get it right. Will come back
210 if somebody asks for it :)
211 - many ->wait methods and Coro::Event could return
212 spuriously without the event having happened.
