3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: fast reloads in cf cause segfaults (coro_state_free->destroy->crash)
6
73.4
8 - remove t/09_timer.t, as it isn't really testing much
9 but was rather flaky in practise.
10 - async_pool coro would keep arguments and callback alive until
11 it was reused.
12 - cancellation of a coroutine could cause spurious idle calls
13 in cede_notself.
14
153.3 Sat Jan 6 03:45:00 CET 2007
16 - implement $coro->on_destroy.
17 - Coro::Event blocking semantics have been changed,
18 documented and - hopefully - improved.
19 - fix nice adding, not subtracting, from priority.
20 - fix ->prio and api_is_ready (patch by Mark Hinds).
21 - fixed an assert ("... == prev__cctx->idle_te")
22 that could errronously trigger.
23 - fix various large and small memleaks.
24 - use a (hopefully) more stable cancel implementation
25 that immediately frees the coroutine data.
26 - cede/cede_notself return a status now.
27 - added Coro::guard function.
28 - added a global coroutine pool for jobs (on my machine,
29 I can create and execute 48k simple coros/s with async,
30 and 128k coros with async_pool).
31 - Coro::AIO now uses the coroutine priority as io priority.
32
333.2 Fri Dec 22 05:07:09 CET 2006
34 - improve portability to slightly older perls.
35 - use cleaner coroutine destruction.
36 - simplify configuration for users.
37 - optionally (unrecommended) prefer perl functions over
38 their coro replacements.
39
403.11 Tue Dec 5 13:11:24 CET 2006
41 - fixed some bogus assert's, but as perl.h disables assert even
42 without NDEBUG (thank you very much), not too many people should
43 notice (that did include myself). Andreas König noticed, though :)
44 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
45 it. Also noticed by Andreas König :)
46 - save/restore tainted status.
47 - verified to pass the testsuite on my 5.9.5.
48
493.1 Mon Dec 4 23:03:40 CET 2006
50 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
51 - incompatible change: transfer flags are now per-state.
52 - give a better error message on deadlock.
53 - document Coro::nready.
54 - enhanced testsuite.
55
563.01 Sun Dec 3 23:47:42 CET 2006
57 - forgot to include Coro::Timer.
58
593.0 Sun Dec 3 22:57:25 CET 2006
60 - the "FINALLY COMPLETELY STABLE" release (coming soon:
61 the "FAMOUS LAST WORDS" release).
62 - implement a new stack sharing algorithm, which uses a stack
63 pool (size currently hardcoded).
64 - make stack sharing mandatory (it no longer uses a heuristic).
65 - eval/die no longer cause weird problems under heavy use.
66 - Coro::Event could cause livelocks if it was used but
67 no Coro::Event watchers were used.
68 - Coro::Event now uses asynccheck as prepare does not
69 check for changed watchers.
70 - Coro::Event allows multiple waiting coros and will wake up one
71 per event.
72 - Coro::Event should be cleaner and more efficient now.
73 - new utility function Coro::unblock_sub.
74 - document the sad fact that Event is no longer reentrant.
75 - putting a coroutine into the ready queue twice could under
76 some circumstances lead to stack corruption.
77 - minor incompatibility: subclassing Coro::State is supported
78 directly now without going through a _coro_state member.
79 - state/coro switching is much faster now.
80 - very minor optimisations and code/documentation cleanup.
81 - avoid problems due to compiler inlining.
82 - removed timers from Coro::Timer -> use AnyEvent instead.
83 - replaced Coro::idle coroutine by (cleaner) idle handler.
84 - updated to newest libcoro.
85 - implement enhanced support for valgrind.
86 - implement is_ready and return value for ready.
87 - removed Coro::Cont, it was a misnomer (it's generators),
88 and it was somewhat annoying to get it right. Will come back
89 if somebody asks for it :)
90 - many ->wait methods and Coro::Event could return
91 spuriously without the event having happened.
92
932.5 Tue Nov 7 12:22:33 CET 2006
94 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
95 use AnyEvent, moved them to Coro/.
96 - added Coro::LWP which contains all the uglyness required to
97 make LWP non-blocking.
98 - should work with perl 5.9.x now (Andreas König made me do it).
99 - fixed another bug in Coro::Select when the timeout was undef.
100 - reuse PL_start_env for all coros, saves some memory per coroutine.
101 - manage PL_top_env differently, hopefully to avoid panic: top_env.
102 - timeout argument was not properly used in Coro::Socket.
103 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
104 - emulate undocumented(!) functionality of IO::Socket required
105 by LWP(!!).
106 - updated eg/lwp to work with newer lwp's.
107 - remove "FATAL: uncaught exception" prefix. Coroutines that die
108 kill the whole process, just as exceptions in the main "coroutine"
109 did already.
110
1112.1 Wed Nov 1 23:01:13 CET 2006
112 - fix a long-standing bug in Coro::Select where select with
113 zero timeout would instead change the current default filehandle.
114 - use a simpler and hopefully more robust way to clone padlists
115 (uses less memory and a perl function instead of our own).
116 - coro can now create a stack guard area on many architectures.
117 - Coro::AIO properly reexports additional functions from IO::AIO.
118 - updated libcoro with a workaround for OS X,
119 pach and testing by Michael Schwern.
120
1212.0 Tue Oct 24 05:47:17 CEST 2006
122 - support additional aio requests in Coro::AIO.
123
1241.9 (never properly released due to a glitch)
125
1261.8 Thu Feb 2 00:59:06 CET 2006
127 - applied suggested patch by SAMV to avoid problems during stupid
128 mark & sweep gc run.
129 - applied patch by Scott Walters for 5.9.3 compatibility.
130
1311.7 Tue Dec 27 01:41:58 CET 2005
132 - added Coro::AIO, a thin wrapper around IO::AIO.
133 - improved Makefile.PL explanations.
134
1351.6 Mon Dec 12 21:30:05 CET 2005
136 - additionally save PM_curpm might fix as-of-yet
137 unseen problems with regex matches being attributed to the
138 wrong package.
139 - add t/10_bugs.t, which currently checks against imho broken
140 perls that use 0.26MB of stack space per Perl_magic_get
141 invocation (newer linuxes) as opposed to the 0.0002MB perl
142 normally uses.
143 - make stacksize configurable for the ultimate debian experience.
144
1451.51 Mon Dec 12 18:48:36 CET 2005
146 - remove debugging warn() accidentally left in Coro::Select.
147
1481.5 Tue Nov 29 13:32:44 CET 2005
149 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
150 - fix Coro::Select 'select'.
151 - strict'ify some modules.
152 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
153 - use XSLoader in selected modules.
154 - remove some 5.6 compatibility cruft.
155
1561.4 Tue Sep 6 00:11:05 CEST 2005
157 - libcoro did not take into account the trampoline on amd64,
158 when 'l'inux method was used.
159
1601.31 Tue Aug 30 23:31:33 CEST 2005
161 - some portability fixes/workarounds.
162
1631.3 Sat Aug 20 03:08:56 CEST 2005
164 - no code changes. module seems to work fine.
165 - improve Coro::State docs, remove reference to nonexisting
166 Coro::State::flush method.
167 - no longer autodetect windows, present it as an option instead.
168
1691.2 Mon May 16 02:00:55 CEST 2005
170 - included libcoro.c earlier in State.xs, might improve portability.
171 - use a faster and possibly more stable Coro::Cont implementation.
172 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
173 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
174 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
175
1761.11 Thu Mar 3 18:00:52 CET 2005
177 - change of contact address.
178
1791.1 Tue Feb 22 20:51:16 CET 2005
180 - support [l]inux method on amd64.
181 - allow some context switches while compiling/eval'ing.
182
1831.0 Tue Aug 10 03:47:27 CEST 2004
184 - Event 0.89 fixes the bug again.
185 - fix the remaining(??) memleak. I didn't free the cache-AV for
186 padlists, so one AV per created anon-sub leaked.
187
1880.97 Fri May 14 15:23:32 CEST 2004
189 - remove stupid gcc extension that was an experiment only anyway.
190
1910.96 Thu May 13 18:09:29 CEST 2004
192 - tell people if they have yet another broken Event variant.
193 - made Coro to work _better_ with threads (it seems that, as long
194 as you use Coros in one thread only everything will work fine.
195 Looking at the perl source the problem might be missing locking
196 between Coro and some perl internal routines. That's not easily
197 fixable).
198 - (hopefully) got rid of the static xnext inside transfer.
199
2000.95 Sun Feb 15 03:20:28 CET 2004
201 - removed Coro::State::flush, implemented a new and much
202 faster caching mechanism by attaching magic to the CV.
203 - a memleak with (real) closures remains.
204 - dramatically reduced size of stacks to 65536 (linux/x86), after
205 observing that even myhttpd never had more than a kilobyte
206 of stack in use (stack is still only physically allocated in
207 pagesize increments for systems suporting mmap).
208 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
209 - fix for threaded perl.
210
2110.9 Sun Nov 23 04:32:39 CET 2003
212 - fix a few very hard to track down but (of course) stupid
213 memory leaks.
214 - stringify version number to avoid locale problems :(.
215 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
216 hopefully ignoring it "just works".
217
2180.8 Wed Nov 5 19:38:40 CET 2003
219 - port to perl5.005_03, but only 5.8.x+ is supported!
220 - honor LocalAddr even without LocalPort in Coro::Socket.
221
2220.7 Tue May 27 03:12:38 CEST 2003
223 - the version jump indicates some level of testing, not gobs
224 of new features.
225 - uh... I found the prompt function in ExtUtils::MakeMaker.
226 Highly correct stuff, that is...
227 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
228 the fix is not well understood by the author, so beware :(.
229
2300.652 Thu May 8 02:54:46 CEST 2003
231 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
232 cause version 4 doesn't have ucontext.
233 - Benjamin Reed reported that setjmp works fine on darwin,
234 so preselect it.
235
2360.651 Sat Mar 29 15:00:23 CET 2003
237 - fix a bug in Coro::Handle where some bytes could get lost
238 on reading, reported by jason@nichego.net.
239
2400.65 Sun Mar 23 00:08:26 CET 2003
241 - added a README.linux-glibc.
242 - new module Coro::Select.
243 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
244 (I never claimed that I know what I am doing ;).
245 - set default to setjmp/longjmp on non-x86-linux.
2 246
30.6 Thu Nov 21 11:09:06 CET 2002 2470.6 Thu Nov 21 11:09:06 CET 2002
4 - made lazy context switching the default. 248 - made lazy context switching the default.
5 - fixed the bug where SemaphoreSet::guard 249 - fixed the bug where SemaphoreSet::guard
6 was the same as timed_guard and timed_guard was missing. 250 was the same as timed_guard and timed_guard was missing.
