11 | 5.0 |
|
|
12 | - NEW ARCHITECTURE: use 4.912 for the stable version. |
|
|
13 | - bump API version to 7 - all dependents must be recompiled. |
|
|
14 | - Coro::Semaphore->adjust didn't correctly wake up enough waiters. |
|
|
15 | - async_pool did free a scalar value twice |
|
|
16 | ("Attempt to unreference..."). |
|
|
17 | - perl's process emulation is now not even theoretically supported |
|
|
18 | anymore. |
|
|
19 | - directly patch the entersub opcode calling SLF functions (cede, |
|
|
20 | transfer and so on). this does speed up context switching, but |
|
|
21 | more importanly, it frees us from the hardcoded behaviour of |
|
|
22 | entersub, so we might actually be able to return something from |
|
|
23 | those functions and atcually create new ones. |
|
|
24 | - take advantage of __builtin_frame_address on gcc. |
|
|
25 | - expose THX in coroapi (not sure whether this was a wise decision, |
|
|
26 | as "threaded" perls are running at half speed anyways). |
|
|
27 | - implement execute_slf (schedule-like-function) interface that makes |
|
|
28 | it possible to implement schedule-like-functions in XS. |
|
|
29 | - use new SLF interface to massively speed up Coro::EV by roughly a factor |
|
|
30 | of two. |
|
|
31 | - removed timed_down and timed_guard functions - they were not being used |
|
|
32 | anyways and should be replaced by a more generic mechanism - and were |
|
|
33 | annoying to support anyways : |
|
|
34 | - used new SLF interface to massively speed up Coro::Semaphore by a factor |
|
|
35 | of three. |
|
|
36 | - forgot to include Coro/libcoro/README in the dist for all these years. |
|
|
37 | - work around a freebsd pthreads bug (manual testcancel is required as |
|
|
38 | pthread_cond_wait isn't a cancellation point on freebsd). |
|
|
39 | |
|
|
40 | 4.913 Sat Nov 15 07:58:28 CET 2008 |
|
|
41 | - async_pool did free a scalar value twice |
|
|
42 | ("Attempt to unreference..."). |
|
|
43 | |
|
|
44 | 4.912 Thu Nov 13 18:31:23 CET 2008 |
|
|
45 | - minor cleanups. |
|
|
46 | - use much larger stacks on linux and perl < 5.8.8. |
|
|
47 | - Coro::Debug::new_unix_server did not unlink the socket |
|
|
48 | when destroyed. |
|
|
49 | |
|
|
50 | 4.911 Tue Nov 11 04:26:17 CET 2008 |
|
|
51 | - "port" to threaded perls. |
|
|
52 | |
|
|
53 | 4.91 Mon Nov 10 05:36:38 CET 2008 |
|
|
54 | - the ->throw exception object no longer leaks. |
|
|
55 | - creating a new cctx leaked a scopestack entry (memleak). |
|
|
56 | - new coroutines didn't get created with a zero flags field |
|
|
57 | (unknown impact). |
|
|
58 | - calling ->throw on a not-yet-started coroutine should now work |
|
|
59 | instead of being ignored. |
|
|
60 | - ->throw is now supported on Coro::State objects. |
|
|
61 | - clean up cctx creation code a bit. |
|
|
62 | - entersub is actually a UNOP, not a LOGOP (not a bugfix). |
|
|
63 | |
|
|
64 | 4.9 Sat Nov 8 17:45:27 CET 2008 |
|
|
65 | - (libcoro) did not preserve rbp with CORO_ASM (we are getting there). |
|
|
66 | - (libcoro) no longer leak threads in the experimental pthread backend, |
|
|
67 | also speed it up considerably. |
|
|
68 | - (libcoro) do not rely on makecontext passing void *'s unscathed. |
|
|
69 | - fix compiletime dependencies on libcoro in the Makefile. |
|
|
70 | - cctx_count wasn't always updated properly. |
|
|
71 | - Coro::State::cctx_stacksize wasn't applied correctly. |
|
|
72 | - new function Coro::State::cctx_max_idle. |
|
|
73 | - the default max number of idle C contexts is now 4. |
|
|
74 | - (libcoro) try harder to get _setjmp/_longjmp. |
|
|
75 | - (libcoro) cleanup and extend the libcoro API to officially |
|
|
76 | allow the creation of empty source contexts. |
|
|
77 | - very experimental workaround for the totally broken netbsd platform. |
|
|
78 | - tried to hack around openbsd bugs. |
|
|
79 | |
|
|
80 | 4.804 Wed Nov 5 16:36:00 CET 2008 |
|
|
81 | - Coro::Debug::new_unix_server would not create a non-blocking listening |
|
|
82 | socket, sometimes causing freezes. |
|
|
83 | - (libcoro) fix misaligned stack points for setjmp and assembly |
|
|
84 | methods, which can cause crashes on x86/x86_64 with a sufficiently |
|
|
85 | aggressive compiler. |
|
|
86 | - new function: Coro::Debug::new_tcp_server. |
|
|
87 | - move ->throw into the Coro class because it only works on coro objects. |
|
|
88 | |
|
|
89 | 4.803 Mon Nov 3 17:16:12 CET 2008 |
|
|
90 | - (libcoro) use a global asm statement to become independent of gcc |
|
|
91 | otpimisations for CORO_ASM (thanks to pippijn for the idea). |
|
|
92 | - try to workaround yet another broken bsd, this time dragonfly. |
|
|
93 | |
|
|
94 | 4.802 Thu Oct 30 10:56:12 CET 2008 |
|
|
95 | - support -fno-omit-frame-pointer on x86 with the assembly method. |
|
|
96 | - tune 01_unblock.t tests a bit. |
|
|
97 | |
|
|
98 | 4.801 Wed Oct 22 18:33:37 CEST 2008 |
|
|
99 | - improve readline speed for very long "lines". |
|
|
100 | - backport to 5.8.8. |
|
|
101 | |
|
|
102 | 4.8 Thu Oct 2 13:34:40 CEST 2008 |
|
|
103 | - new function Coro::AIO::aio_wait. |
|
|
104 | - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent". |
|
|
105 | - greatly speed up and reduce memory usage of Coro::AIO requests. |
|
|
106 | - implement some other µ-optimisations. |
|
|
107 | |
|
|
108 | 4.749 Mon Sep 29 14:40:12 CEST 2008 |
|
|
109 | - port to slow and broken pseudo-threaded perls. (courtesy pippijn). |
|
|
110 | |
|
|
111 | 4.748 Sat Sep 27 14:03:19 CEST 2008 |
|
|
112 | - implement, but do not document, PerlIO::cede(granularity). |
|
|
113 | - Coro::Storable forgot to wrap Storable::pstore. |
|
|
114 | - work around the multitude of leaks and memory corruption |
|
|
115 | bugs in PerlIO::via by using our own C-level perliol. As a side |
|
|
116 | effect, Coro::Storable is now much, much, much faster. |
|
|
117 | |
|
|
118 | 4.747 Tue Sep 23 01:59:41 CEST 2008 |
|
|
119 | - fix a per-cv memleak (one empty array was leaked per |
|
|
120 | code reference). |
|
|
121 | - avoid a crash in coro->call|rss when the coroutine was already |
|
|
122 | destroyed (most noticably when using Coro::Debug::ps :) |
|
|
123 | - also protect *Storable::FILE. |
|
|
124 | - push up default storable granularity to 20ms. |
|
|
125 | |
|
|
126 | 4.746 Sun Sep 21 03:22:20 CEST 2008 |
|
|
127 | - be more insistent on locking Storable against reentrancy |
|
|
128 | in Coro::Storable. |
|
|
129 | - move swap_def?v and throw to Coro::State, as documented. |
|
|
130 | |
|
|
131 | 4.745 Thu Jul 24 00:14:38 CEST 2008 |
|
|
132 | - remove debugging code related to MgPV_nolen_const, also try to |
|
|
133 | make it compile with perl 5.8.6 (yes, apple apparently loves |
|
|
134 | outdated software). Reported by John S. |
|
|
135 | |
|
|
136 | 4.744 Tue Jul 8 22:06:35 CEST 2008 |
|
|
137 | - correctly provide default DIE/WARN handlers as documented. |
|
|
138 | - also overwrite PL_vtbl_sigelem.svt_clear, even though current |
|
|
139 | implementations inside perl work fine for us. |
|
|
140 | |
|
|
141 | 4.743 Mon Jun 16 00:21:57 CEST 2008 |
|
|
142 | - when using Coro::EV without running EV::loop it could |
|
|
143 | result in busy-waiting for events, this has been fixed. |
|
|
144 | - reduce codesize and improve performance by using EV_DEFAULT_UC. |
|
|
145 | |
|
|
146 | 4.742 Sat May 31 14:10:21 CEST 2008 |
|
|
147 | - implement a workaround for (some) perl <5.8.8 versions. |
|
|
148 | - require EV 3.3+. |
|
|
149 | |
|
|
150 | 4.741 Fri May 30 23:33:09 CEST 2008 |
|
|
151 | - tell netbsd how utterly broken their imitation of an OS is |
|
|
152 | and refuse to build by default if pthreads are in use. |
|
|
153 | - switch to "s" method on all bsd's by default, as their ucontext |
|
|
154 | stuff seems just too broken. |
|
|
155 | - fix a bug in Coro::Select. |
|
|
156 | |
|
|
157 | 4.74 Thu May 29 20:05:31 CEST 2008 |
|
|
158 | - do not test Coro::LWP for lack of dependencies. |
|
|
159 | - do not test Coro::Select for lack of working perls. |
|
|
160 | |
|
|
161 | 4.73 Thu May 29 2008 |
|
|
162 | - fix a bug in Coro::EV which would cause it to block despite |
|
|
163 | there being runnable coroutines. |
|
|
164 | - sprinkle "no warnings" freely over everything, also suppress |
|
|
165 | warnings for some other modules. |
|
|
166 | - fix typo in WSAEWOULDBLOCK. |
|
|
167 | |
|
|
168 | 4.72 Sun May 25 05:14:36 CEST 2008 |
|
|
169 | - tweak META.yaml a bit, unfortunately, there is no documented way |
|
|
170 | to have optional dependencies with CPAN. doh :( |
|
|
171 | - avoid running some tests on windows because they would fail due to |
|
|
172 | perl bug (broken fork, broken pipes...). |
|
|
173 | - work around perl on windows bugs where perl returns undocumented |
|
|
174 | error codes for sysread, syswrite etc. by taking advantage |
|
|
175 | of AnyEvent's workaround for that problem. |
|
|
176 | - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around |
|
|
177 | a common perl implementation bug on windows. |
|
|
178 | - use unix domain sockets in testsuite to work around |
|
|
179 | common perl implementation bugs on widows (they are emulated by |
|
|
180 | tcp sockets on windows. ugh.) |
|
|
181 | |
|
|
182 | 4.71 Sat May 24 20:01:27 CEST 2008 |
|
|
183 | - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()"). |
|
|
184 | - take advantage of async name resolution of AnyEvent::Util. |
|
|
185 | - work around brutal inet_aton override in Coro::LWP. |
|
|
186 | - take advantage of the readyhook in Coro::EV, for smoother |
|
|
187 | scheduling. |
|
|
188 | |
|
|
189 | 4.7 Sun May 11 00:32:19 CEST 2008 |
|
|
190 | - completely reworked the Coro manpage. |
|
|
191 | - added Coro::AnyEvent, generic event loop integration. |
|
|
192 | - implement cancel, ready and kill commands in Coro::Debug. |
|
|
193 | - document find_coro in Coro::Debug. |
|
|
194 | - incompatible change: rename has_stack to has_cctx. |
|
|
195 | - Coro::AIO and Coro::BDB no longer force event model detection, |
|
|
196 | use AnyEvent::AIO and AnyEvent::BDB. |
|
|
197 | |
|
|
198 | 4.6 Sat Apr 26 10:05:14 CEST 2008 |
|
|
199 | - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported |
|
|
200 | by the Coro module. It was a mistake to have it in the first place. |
|
|
201 | - (experimental) support for activestate perl 5.10 (method "w"). |
|
|
202 | - (experimental) support for strawberry perl (method "a"). |
|
|
203 | - coro_sigelem_set did not return a value although it had to, |
|
|
204 | actual impact unknown. |
|
|
205 | |
|
|
206 | 4.51 Mon Apr 14 13:28:27 CEST 2008 |
|
|
207 | - make it compile again on 5.8. |
|
|
208 | |
|
|
209 | 4.50 Thu Apr 10 09:43:17 CEST 2008 |
|
|
210 | - I did it twice! (see 4.49). |
|
|
211 | |
|
|
212 | 4.49 Sun Apr 6 21:23:31 CEST 2008 |
|
|
213 | - grr, instead of compiling the recent changes on 5.10 only they |
|
|
214 | were compiled on 5.8 only. |
|
|
215 | |
|
|
216 | 4.48 Sun Apr 6 20:36:46 CEST 2008 |
|
|
217 | - allow coroutine switches during eval's under 5.10.x, as it seems |
|
|
218 | the parser is a per-interpreter option now, so this is safe |
|
|
219 | (this might fix the odd crashing bug). |
|
|
220 | - drop support for 5.9.x versions: they are dead, jim. |
|
|
221 | |
|
|
222 | 4.47 Sun Apr 6 00:37:52 CEST 2008 |
|
|
223 | - force cctx allocation on API calls: we know we need to force one |
|
|
224 | and gcc actually manages to confuse our heuristic nowadays, |
|
|
225 | leading to crashes and worse. |
|
|
226 | - document force_cctx. |
|
|
227 | |
|
|
228 | 4.46 Fri Apr 4 22:05:43 CEST 2008 |
|
|
229 | - upgrade libcoro, resulting in pthread-backend (which was only created |
|
|
230 | to fulfill the rules of the programming languages shootout). |
|
|
231 | |
|
|
232 | 4.45 Thu Mar 13 11:55:36 CET 2008 |
|
|
233 | - fix a file leaking bug in eg/mhyttpd that would allow |
|
|
234 | downloading of any file (reported by oesi). |
|
|
235 | - fix deadlock bug in Coro::Channel (reported by Richard Hundt) |
|
|
236 | (also add testcase). |
|
|
237 | - support Broadcast option in Coro::Socket (patch by Richard Hundt, |
|
|
238 | apparently having loads of fun with that). |
|
|
239 | - implement $state->swap_defsv, ->swap_defav and document ->throw. |
|
|
240 | |
|
|
241 | 4.4 Wed Feb 13 16:44:29 CET 2008 |
|
|
242 | - only assume .cfi pseudo isns exist on GNU/Linux. |
|
|
243 | - add get_timed method to Coro::Channels. |
|
|
244 | - fixed Coro::Debug manpage. |
|
|
245 | - perl 5.11 compatbility improvement based on patch by |
|
|
246 | Andreas König. |
|
|
247 | |
|
|
248 | 4.37 Sun Jan 20 11:25:23 CET 2008 |
|
|
249 | - soften the check for an active parser for perl 5.10 (avoiding |
|
|
250 | "Coro::State::transfer called while parsing" in many cases). |
|
|
251 | |
|
|
252 | 4.36 Sun Jan 13 10:53:56 CET 2008 |
|
|
253 | - reset diehook when terminating from an async_pool as to not |
|
|
254 | trigger any __DIE__ handlers. |
|
|
255 | |
|
|
256 | 4.35 Sun Jan 13 04:14:13 CET 2008 |
|
|
257 | - "bt" debug command now displays any exceptions |
|
|
258 | from longmess and also skips the innermost |
|
|
259 | stackframes, giving more useufl output. |
|
|
260 | - allow backtraces in coroutines blocked in Coro::EV, |
|
|
261 | at a <1% speed hit. |
|
|
262 | - handle localising of $SIG{__WARN__} and __DIE__ |
|
|
263 | properly (with a proper amount of dirty hacking). |
|
|
264 | |
|
|
265 | 4.34 Sat Dec 22 17:49:53 CET 2007 |
|
|
266 | - upgrade to EV version 2.0 API. |
|
|
267 | |
|
|
268 | 4.33 Mon Dec 17 08:36:12 CET 2007 |
|
|
269 | - make Coro::AIO etc. loadable in the absence of EV. |
|
|
270 | |
|
|
271 | 4.32 Mon Dec 17 07:46:02 CET 2007 |
|
|
272 | - majorly improved Coro::Handle's performance with Coro::EV. |
|
|
273 | - implemented the until now mythical Coro::BDB module. |
|
|
274 | - specialcase EV in Coro::AIO and Coro::BDB for extra speed. |
|
|
275 | |
|
|
276 | 4.31 Wed Dec 5 12:32:39 CET 2007 |
|
|
277 | - remove warn statement form Coro::Util. |
|
|
278 | |
|
|
279 | 4.3 Tue Dec 4 20:33:14 CET 2007 |
|
|
280 | - calls to the idle function could cause stack corruption |
|
|
281 | when the stack changed. |
|
|
282 | - do no longer rely on the presence of EV::DNS if EV is used |
|
|
283 | (because it is gone), but instead take avdantage of EV::ADNS |
|
|
284 | if available. |
|
|
285 | - add ($) prototypes to all functions in Coro::Storable. |
|
|
286 | - use a conventional (safer) idle callback in Coro::EV. |
|
|
287 | - do accept quickly in Coro::Debug to avoid endless loops. |
|
|
288 | |
|
|
289 | 4.22 Fri Nov 30 16:04:04 CET 2007 |
|
|
290 | - really use optimised versions for Event and EV in Coro::Util |
|
|
291 | and Coro::Handle. |
|
|
292 | |
|
|
293 | 4.21 Sun Nov 25 10:48:59 CET 2007 |
|
|
294 | - fix a spurious memory read. |
|
|
295 | - Coro::EV no longer keeps the eventloop "alive". |
|
|
296 | |
|
|
297 | 4.2 Fri Nov 9 20:47:05 CET 2007 |
| 8 | - enable/disable tracing from a new coroutine, not a pooled one. |
298 | - enable/disable tracing from a new coroutine, not a pooled one. |
| 9 | - fix a memleak in Coro::Event. |
299 | - fix a memleak in Coro::Event. |
| 10 | - removed killall call from fork_eval. |
300 | - removed killall call from fork_eval. |
| 11 | - made sure store_fd is already loaded so that fork_eval |
301 | - made sure store_fd is already loaded so that fork_eval |
| 12 | does not have to parse autoload in each subprocess. |
302 | does not have to parse autoload in each subprocess. |
| 13 | - only use assembly method if -O switch is in $Config{optimize}. |
303 | - only use assembly method if -O switch is in $Config{optimize}. |
|
|
304 | - add (optional) Coro::EV module, so far the best event loop module |
|
|
305 | directly supported by Coro. |
| 14 | # - if the event model is EV, use EV::DNS to resolve |
306 | - if the event model is EV, use EV::DNS to resolve |
| 15 | # stuff in Coro::Util. |
307 | stuff in Coro::Util. |
| 16 | - don't get confused by multiple event notifications in Coro::Handle. |
