11 | - free_padlist did destroy the names pad, not good, but didn't |
|

12 | seem to bother perl. |
|
|
13 | - use a different method to detect destruction time. |
|
|
14 | - be more careful when freeing padlists just before global |
|
|
15 | destruction. |

17 | 5.11 Tue Nov 25 21:49:05 CET 2008 |
|
|
18 | - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly |
|
|
19 | working code with failed assertions, introducing more bugs than |
|
|
20 | it fixes, requiring elaborate workarounds :( |
|
|
21 | |
|
|
22 | 5.1 Mon Nov 24 08:54:59 CET 2008 |
|
|
23 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
24 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
25 | - Coro::Select did errornously dup the file descriptors |
|
|
26 | and didn't work with all AnyEvent backends. |
|
|
27 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
28 | LWP data transfers. |
|
|
29 | - disassociate c contexts from coro objects - this is agruably more |
|
|
30 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
31 | objects, for added memory savings and speed increases. |
|
|
32 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
33 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
34 | doesn't like this very much (and we *are* a type of entersub). |
|
|
35 | - implement state cloning, just to prove that call/cc can be done. |
|
|
36 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
37 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
38 | do not have this method (and don't need it either). |
|
|
39 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
40 | callbacks. |
|
|
41 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
42 | others. It also makes the debugger happier, as you can trace |
|
|
43 | through the idle threads now. |
|
|
44 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
45 | - eg/event was pretty broken. |
|
|
46 | - better 5.8.6 compatibility. |
|
|
47 | |
|
|
48 | 5.0 Thu Nov 20 10:35:05 CET 2008 |
|
|
49 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |
|
|
50 | stability issues. |
|
|
51 | - bump API version to 7 - all dependents must be recompiled. |
|
|
52 | - removed timed_* functions - they were not being used anyways |
|
|
53 | and should be replaced by a more generic mechanism - |
|
|
54 | and were annoying to support anyways :) |
|
|
55 | - removed SemaphoreSet's waiter method - use sem method instead. |
|
|
56 | - Coro::Semaphore->adjust didn't correctly wake up enough waiters. |
|
|
57 | - async_pool did free a scalar value twice |
|
|
58 | ("Attempt to unreference..."). |
|
|
59 | - fix a longstanding bug where calling terminate on a coro that |
|
|
60 | was waiting for a semaphore that was just becoming available |
|
|
61 | would cause a deadlock (semaphore would get into a state where |
|
|
62 | it was available but waiters were still blocked). |
|
|
63 | - calling throw on a coroutine that is waiting for a semaphore will |
|
|
64 | no longer make it acquire the semaphore (and thus leak a count). |
|
|
65 | - perl's process emulation is now not even theoretically supported |
|
|
66 | anymore. |
|
|
67 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
68 | conversion of callback-style to blocking-style. |
|
|
69 | - new methods $coro->schedule_to and ->cede_to, to specifically |
|
|
70 | schedule or cede to a specific coroutine. |
|
|
71 | - new function Coro::Semaphore::wait. |
|
|
72 | - use named constants in Coro::Channel (Richard Hundt). |
|
|
73 | - directly patch the entersub opcode calling SLF functions (cede, |
|
|
74 | transfer and so on). this does speed up context switching, but |
|
|
75 | more importanly, it frees us from the hardcoded behaviour of |
|
|
76 | entersub, so we might actually be able to return something from |
|
|
77 | those functions and atcually create new ones. |
|
|
78 | - take advantage of __builtin_frame_address on gcc. |
|
|
79 | - expose THX in coroapi (not sure whether this was a wise decision, |
|
|
80 | as "threaded" perls are running at half speed anyways). |
|
|
81 | - implement execute_slf (schedule-like-function) interface that makes |
|
|
82 | it possible to implement schedule-like-functions in XS. |
|
|
83 | - use new SLF interface to massively speed up Coro::EV by roughly a |
|
|
84 | factor of two. |
|
|
85 | - used new SLF interface to massively speed up Coro::Semaphore by a |
|
|
86 | factor of three. |
|
|
87 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
88 | four and reduce its memory usage considerably. |
|
|
89 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
90 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
91 | a new method "sem" to get at the underlying semaphore object. |
|
|
92 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
93 | (in comparison) 20-40% speedup. |
|
|
94 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
95 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
96 | making signals reliable for the first time. |
|
|
97 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
98 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
99 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
100 | a normal async is now very small. |
|
|
101 | - sped up coroutine creation/destruction by 40%. |
|
|
102 | - forgot to include Coro/libcoro/README in the dist for all these years. |
|
|
103 | - work around a freebsd pthreads bug (manual testcancel is required as |
|
|
104 | pthread_cond_wait isn't a cancellation point on freebsd). |
|
|
105 | - use new rouse functions to speed up and simplify Coro::BDB. |
|
|
106 | - make "prefer perl native functions" work with threaded perls. |
|
|
107 | - condense Coro::Debug ps output, hint at v and w flags. |
|
|
108 | - (libcoro) lots of minor cleanups and portability improvements. |
|
|
109 | |
|
|
110 | 4.914 Wed Nov 19 12:54:18 CET 2008 |
|
|
111 | - fix a disastrous bug in the readline optimisation |
|
|
112 | introduced in 4.801. |
|
|
113 | |
|
|
114 | 4.913 Sat Nov 15 07:58:28 CET 2008 |
|
|
115 | - async_pool did free a scalar value twice |
|
|
116 | ("Attempt to unreference..."). |
|
|
117 | |
|
|
118 | 4.912 Thu Nov 13 18:31:23 CET 2008 |
|
|
119 | - minor cleanups. |
|
|
120 | - use much larger stacks on linux and perl < 5.8.8. |
|
|
121 | - Coro::Debug::new_unix_server did not unlink the socket |
|
|
122 | when destroyed. |
|
|
123 | |
|
|
124 | 4.911 Tue Nov 11 04:26:17 CET 2008 |
|
|
125 | - "port" to threaded perls. |
|
|
126 | |
|
|
127 | 4.91 Mon Nov 10 05:36:38 CET 2008 |
|
|
128 | - the ->throw exception object no longer leaks. |
|
|
129 | - creating a new cctx leaked a scopestack entry (memleak). |
|
|
130 | - new coroutines didn't get created with a zero flags field |
|
|
131 | (unknown impact). |
|
|
132 | - calling ->throw on a not-yet-started coroutine should now work |
|
|
133 | instead of being ignored. |
|
|
134 | - ->throw is now supported on Coro::State objects. |
|
|
135 | - clean up cctx creation code a bit. |
|
|
136 | - entersub is actually a UNOP, not a LOGOP (not a bugfix). |
|
|
137 | |
|
|
138 | 4.9 Sat Nov 8 17:45:27 CET 2008 |
|
|
139 | - (libcoro) did not preserve rbp with CORO_ASM (we are getting there). |
|
|
140 | - (libcoro) no longer leak threads in the experimental pthread backend, |
|
|
141 | also speed it up considerably. |
|
|
142 | - (libcoro) do not rely on makecontext passing void *'s unscathed. |
|
|
143 | - fix compiletime dependencies on libcoro in the Makefile. |
|
|
144 | - cctx_count wasn't always updated properly. |
|
|
145 | - Coro::State::cctx_stacksize wasn't applied correctly. |
|
|
146 | - new function Coro::State::cctx_max_idle. |
|
|
147 | - the default max number of idle C contexts is now 4. |
|
|
148 | - (libcoro) try harder to get _setjmp/_longjmp. |
|
|
149 | - (libcoro) cleanup and extend the libcoro API to officially |
|
|
150 | allow the creation of empty source contexts. |
|
|
151 | - very experimental workaround for the totally broken netbsd platform. |
|
|
152 | - tried to hack around openbsd bugs. |
|
|
153 | |
|
|
154 | 4.804 Wed Nov 5 16:36:00 CET 2008 |
|
|
155 | - Coro::Debug::new_unix_server would not create a non-blocking listening |
|
|
156 | socket, sometimes causing freezes. |
|
|
157 | - (libcoro) fix misaligned stack points for setjmp and assembly |
|
|
158 | methods, which can cause crashes on x86/x86_64 with a sufficiently |
|
|
159 | aggressive compiler. |
|
|
160 | - new function: Coro::Debug::new_tcp_server. |
|
|
161 | - move ->throw into the Coro class because it only works on coro objects. |
|
|
162 | |
|
|
163 | 4.803 Mon Nov 3 17:16:12 CET 2008 |
|
|
164 | - (libcoro) use a global asm statement to become independent of gcc |
|
|
165 | otpimisations for CORO_ASM (thanks to pippijn for the idea). |
|
|
166 | - try to workaround yet another broken bsd, this time dragonfly. |
|
|
167 | |
|
|
168 | 4.802 Thu Oct 30 10:56:12 CET 2008 |
|
|
169 | - support -fno-omit-frame-pointer on x86 with the assembly method. |
|
|
170 | - tune 01_unblock.t tests a bit. |
|
|
171 | |
|
|
172 | 4.801 Wed Oct 22 18:33:37 CEST 2008 |
|
|
173 | - improve readline speed for very long "lines". |
|
|
174 | - backport to 5.8.8. |
|
|
175 | |
|
|
176 | 4.8 Thu Oct 2 13:34:40 CEST 2008 |
|
|
177 | - new function Coro::AIO::aio_wait. |
|
|
178 | - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent". |
|
|
179 | - greatly speed up and reduce memory usage of Coro::AIO requests. |
|
|
180 | - implement some other ยต-optimisations. |
|
|
181 | |
|
|
182 | 4.749 Mon Sep 29 14:40:12 CEST 2008 |
|
|
183 | - port to slow and broken pseudo-threaded perls. (courtesy pippijn). |
|
|
184 | |
|
|
185 | 4.748 Sat Sep 27 14:03:19 CEST 2008 |
|
|
186 | - implement, but do not document, PerlIO::cede(granularity). |
|
|
187 | - Coro::Storable forgot to wrap Storable::pstore. |
|
|
188 | - work around the multitude of leaks and memory corruption |
|
|
189 | bugs in PerlIO::via by using our own C-level perliol. As a side |
|
|
190 | effect, Coro::Storable is now much, much, much faster. |
|
|
191 | |
|
|
192 | 4.747 Tue Sep 23 01:59:41 CEST 2008 |
|
|
193 | - fix a per-cv memleak (one empty array was leaked per |
|
|
194 | code reference). |
|
|
195 | - avoid a crash in coro->call|rss when the coroutine was already |
|
|
196 | destroyed (most noticably when using Coro::Debug::ps :) |
|
|
197 | - also protect *Storable::FILE. |
|
|
198 | - push up default storable granularity to 20ms. |
|
|
199 | |
|
|
200 | 4.746 Sun Sep 21 03:22:20 CEST 2008 |
|
|
201 | - be more insistent on locking Storable against reentrancy |
|
|
202 | in Coro::Storable. |
|
|
203 | - move swap_def?v and throw to Coro::State, as documented. |
|
|
204 | |
|
|
205 | 4.745 Thu Jul 24 00:14:38 CEST 2008 |
|
|
206 | - remove debugging code related to MgPV_nolen_const, also try to |
|
|
207 | make it compile with perl 5.8.6 (yes, apple apparently loves |
|
|
208 | outdated software). Reported by John S. |
|
|
209 | |
|
|
210 | 4.744 Tue Jul 8 22:06:35 CEST 2008 |
|
|
211 | - correctly provide default DIE/WARN handlers as documented. |
|
|
212 | - also overwrite PL_vtbl_sigelem.svt_clear, even though current |
|
|
213 | implementations inside perl work fine for us. |
|
|
214 | |
|
|
215 | 4.743 Mon Jun 16 00:21:57 CEST 2008 |
|
|
216 | - when using Coro::EV without running EV::loop it could |
|
|
217 | result in busy-waiting for events, this has been fixed. |
|
|
218 | - reduce codesize and improve performance by using EV_DEFAULT_UC. |
|
|
219 | |
|
|
220 | 4.742 Sat May 31 14:10:21 CEST 2008 |
|
|
221 | - implement a workaround for (some) perl <5.8.8 versions. |
|
|
222 | - require EV 3.3+. |
|
|
223 | |
|
|
224 | 4.741 Fri May 30 23:33:09 CEST 2008 |
|
|
225 | - tell netbsd how utterly broken their imitation of an OS is |
|
|
226 | and refuse to build by default if pthreads are in use. |
|
|
227 | - switch to "s" method on all bsd's by default, as their ucontext |
|
|
228 | stuff seems just too broken. |
|
|
229 | - fix a bug in Coro::Select. |
|
|
230 | |
|
|
231 | 4.74 Thu May 29 20:05:31 CEST 2008 |
|
|
232 | - do not test Coro::LWP for lack of dependencies. |
|
|
233 | - do not test Coro::Select for lack of working perls. |
|
|
234 | |
|
|
235 | 4.73 Thu May 29 2008 |
|
|
236 | - fix a bug in Coro::EV which would cause it to block despite |
|
|
237 | there being runnable coroutines. |
|
|
238 | - sprinkle "no warnings" freely over everything, also suppress |
|
|
239 | warnings for some other modules. |
|
|
240 | - fix typo in WSAEWOULDBLOCK. |
|
|
241 | |
|
|
242 | 4.72 Sun May 25 05:14:36 CEST 2008 |
|
|
243 | - tweak META.yaml a bit, unfortunately, there is no documented way |
|
|
244 | to have optional dependencies with CPAN. doh :( |
|
|
245 | - avoid running some tests on windows because they would fail due to |
|
|
246 | perl bug (broken fork, broken pipes...). |
|
|
247 | - work around perl on windows bugs where perl returns undocumented |
|
|
248 | error codes for sysread, syswrite etc. by taking advantage |
|
|
249 | of AnyEvent's workaround for that problem. |
|
|
250 | - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around |
|
|
251 | a common perl implementation bug on windows. |
|
|
252 | - use unix domain sockets in testsuite to work around |
|
|
253 | common perl implementation bugs on widows (they are emulated by |
|
|
254 | tcp sockets on windows. ugh.) |
| 7 | |
255 | |
| 8 | 4.71 Sat May 24 20:01:27 CEST 2008 |
256 | 4.71 Sat May 24 20:01:27 CEST 2008 |
| 9 | - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()"). |
257 | - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()"). |
| 10 | - take advantage of async name resolution of AnyEvent::Util. |
258 | - take advantage of async name resolution of AnyEvent::Util. |
| 11 | - work around brutal inet_aton override in Coro::LWP. |
259 | - work around brutal inet_aton override in Coro::LWP. |
