1 Revision history for Perl extension Coro.
2
3 TODO: transfer flags must be per state
4
5 3.0
6 - the "FINALLY COMPLETELY STABLE" release (coming soon:
7 the "FAMOUS LAST WORDS" release).
8 - implement a new stack sharing algorithm, which uses a stack
9 pool (size currently hardcoded).
10 - make stack sharing mandatory (it no longer uses a heuristic).
11 - eval/die no longer cause weird problems under heavy use.
12 - Coro::Event could cause livelocks if it was used but
13 no Coro::Event watchers were used.
14 - Coro::Event now uses asynccheck as prepare does not
15 check for changed watchers.
16 - Coro::Event allows multiple waiting coros and will wake up one
17 per event.
18 - Coro::Event should be cleaner and more efficient now.
19 - new utility function Coro::unblock_sub.
20 - document the sad fact that Event is no longer reentrant.
21 - putting a coroutine into the ready queue twice could under
22 some circumstances lead to stack corruption.
23 - minor incompatibility: subclassing Coro::State is supported
24 directly now without going through a _coro_state member.
25 - state/coro switching is much faster now.
26 - very minor optimisations and code/documentation cleanup.
27 - avoid problems due to compiler inlining.
28 - removed timers from Coro::Timer -> use AnyEvent instead.
29 - replaced Coro::idle coroutine by (cleaner) idle handler.
30 - updated to newest libcoro.
31 - implement enhanced support for valgrind.
32 - implement is_ready and return value for ready.
33 - removed Coro::Cont, it was a misnomer (it's generators),
34 and it was somewhat annoying to get it right. Will come back
35 if somebody asks for it :)
36 - many ->wait methods and Coro::Event could return
37 spuriously without the event having happened.
38
39 2.5 Tue Nov 7 12:22:33 CET 2006
40 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
41 use AnyEvent, moved them to Coro/.
42 - added Coro::LWP which contains all the uglyness required to
43 make LWP non-blocking.
44 - should work with perl 5.9.x now (Andreas König made me do it).
45 - fixed another bug in Coro::Select when the timeout was undef.
46 - reuse PL_start_env for all coros, saves some memory per coroutine.
47 - manage PL_top_env differently, hopefully to avoid panic: top_env.
48 - timeout argument was not properly used in Coro::Socket.
49 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
50 - emulate undocumented(!) functionality of IO::Socket required
51 by LWP(!!).
52 - updated eg/lwp to work with newer lwp's.
53 - remove "FATAL: uncaught exception" prefix. Coroutines that die
54 kill the whole process, just as exceptions in the main "coroutine"
55 did already.
56
57 2.1 Wed Nov 1 23:01:13 CET 2006
58 - fix a long-standing bug in Coro::Select where select with
59 zero timeout would instead change the current default filehandle.
60 - use a simpler and hopefully more robust way to clone padlists
61 (uses less memory and a perl function instead of our own).
62 - coro can now create a stack guard area on many architectures.
63 - Coro::AIO properly reexports additional functions from IO::AIO.
64 - updated libcoro with a workaround for OS X,
65 pach and testing by Michael Schwern.
66
67 2.0 Tue Oct 24 05:47:17 CEST 2006
68 - support additional aio requests in Coro::AIO.
69
70 1.9 (never properly released due to a glitch)
71
72 1.8 Thu Feb 2 00:59:06 CET 2006
73 - applied suggested patch by SAMV to avoid problems during stupid
74 mark & sweep gc run.
75 - applied patch by Scott Walters for 5.9.3 compatibility.
76
77 1.7 Tue Dec 27 01:41:58 CET 2005
78 - added Coro::AIO, a thin wrapper around IO::AIO.
79 - improved Makefile.PL explanations.
80
81 1.6 Mon Dec 12 21:30:05 CET 2005
82 - additionally save PM_curpm might fix as-of-yet
83 unseen problems with regex matches being attributed to the
84 wrong package.
85 - add t/10_bugs.t, which currently checks against imho broken
86 perls that use 0.26MB of stack space per Perl_magic_get
87 invocation (newer linuxes) as opposed to the 0.0002MB perl
88 normally uses.
89 - make stacksize configurable for the ultimate debian experience.
90
91 1.51 Mon Dec 12 18:48:36 CET 2005
92 - remove debugging warn() accidentally left in Coro::Select.
93
94 1.5 Tue Nov 29 13:32:44 CET 2005
95 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
96 - fix Coro::Select 'select'.
97 - strict'ify some modules.
98 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
99 - use XSLoader in selected modules.
100 - remove some 5.6 compatibility cruft.
101
102 1.4 Tue Sep 6 00:11:05 CEST 2005
103 - libcoro did not take into account the trampoline on amd64,
104 when 'l'inux method was used.
105
106 1.31 Tue Aug 30 23:31:33 CEST 2005
107 - some portability fixes/workarounds.
108
109 1.3 Sat Aug 20 03:08:56 CEST 2005
110 - no code changes. module seems to work fine.
111 - improve Coro::State docs, remove reference to nonexisting
112 Coro::State::flush method.
113 - no longer autodetect windows, present it as an option instead.
114
115 1.2 Mon May 16 02:00:55 CEST 2005
116 - included libcoro.c earlier in State.xs, might improve portability.
117 - use a faster and possibly more stable Coro::Cont implementation.
118 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
119 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
120 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
121
122 1.11 Thu Mar 3 18:00:52 CET 2005
123 - change of contact address.
124
125 1.1 Tue Feb 22 20:51:16 CET 2005
126 - support [l]inux method on amd64.
127 - allow some context switches while compiling/eval'ing.
128
129 1.0 Tue Aug 10 03:47:27 CEST 2004
130 - Event 0.89 fixes the bug again.
131 - fix the remaining(??) memleak. I didn't free the cache-AV for
132 padlists, so one AV per created anon-sub leaked.
133
134 0.97 Fri May 14 15:23:32 CEST 2004
135 - remove stupid gcc extension that was an experiment only anyway.
136
137 0.96 Thu May 13 18:09:29 CEST 2004
138 - tell people if they have yet another broken Event variant.
139 - made Coro to work _better_ with threads (it seems that, as long
140 as you use Coros in one thread only everything will work fine.
141 Looking at the perl source the problem might be missing locking
142 between Coro and some perl internal routines. That's not easily
143 fixable).
144 - (hopefully) got rid of the static xnext inside transfer.
145
146 0.95 Sun Feb 15 03:20:28 CET 2004
147 - removed Coro::State::flush, implemented a new and much
148 faster caching mechanism by attaching magic to the CV.
149 - a memleak with (real) closures remains.
150 - dramatically reduced size of stacks to 65536 (linux/x86), after
151 observing that even myhttpd never had more than a kilobyte
152 of stack in use (stack is still only physically allocated in
153 pagesize increments for systems suporting mmap).
154 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
155 - fix for threaded perl.
156
157 0.9 Sun Nov 23 04:32:39 CET 2003
158 - fix a few very hard to track down but (of course) stupid
159 memory leaks.
160 - stringify version number to avoid locale problems :(.
161 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
162 hopefully ignoring it "just works".
163
164 0.8 Wed Nov 5 19:38:40 CET 2003
165 - port to perl5.005_03, but only 5.8.x+ is supported!
166 - honor LocalAddr even without LocalPort in Coro::Socket.
167
168 0.7 Tue May 27 03:12:38 CEST 2003
169 - the version jump indicates some level of testing, not gobs
170 of new features.
171 - uh... I found the prompt function in ExtUtils::MakeMaker.
172 Highly correct stuff, that is...
173 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
174 the fix is not well understood by the author, so beware :(.
175
176 0.652 Thu May 8 02:54:46 CEST 2003
177 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
178 cause version 4 doesn't have ucontext.
179 - Benjamin Reed reported that setjmp works fine on darwin,
180 so preselect it.
181
182 0.651 Sat Mar 29 15:00:23 CET 2003
183 - fix a bug in Coro::Handle where some bytes could get lost
184 on reading, reported by jason@nichego.net.
185
186 0.65 Sun Mar 23 00:08:26 CET 2003
187 - added a README.linux-glibc.
188 - new module Coro::Select.
189 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
190 (I never claimed that I know what I am doing ;).
191 - set default to setjmp/longjmp on non-x86-linux.
192
193 0.6 Thu Nov 21 11:09:06 CET 2002
194 - made lazy context switching the default.
195 - fixed the bug where SemaphoreSet::guard
196 was the same as timed_guard and timed_guard was missing.
197 - fix a memleak in Coro::Timer.
198 - reclassified context sharing as not experimental.
199
200 0.534 Sun Apr 14 03:05:12 CEST 2002
201 - fixed backspace => tab in header parsing (myhttpd).
202 - added eg/readline, for elmex.
203 - Coro::Event now calls ->start on first call instead of
204 ->again, which created wrong timeouts for the first ->next.
205 - fixed a bug where Coro::Socket returned a closed socket instead
206 of nothing on ECONNREFUSED and similar error conditions.
207
208 0.533 Mon Feb 18 18:49:40 CET 2002
209 - adapt to finally working Event-0.85.
210 - fixed buggy event initialization (trapped under windows, but how
211 could it possibly have worked anywhere?)
212
213 0.532 Wed Jan 16 02:45:32 CET 2002
214 - removed the reference to pp_entersub, might work on
215 (some) win32 perls now (testsuite works under cygwin,
216 without Event, which freezes).
217
218 0.531 Mon Dec 10 22:18:44 CET 2001
219 - Fixed a bug in SemaphoreSet::timed_down.
220
221 0.53 Tue Nov 27 21:11:13 CET 2001
222 - some tests for Event.
223 - slightly different internal architecture to get refcnt into the object
224 and not the reference. might fix a few bugs, certainly did introduce
225 new ones.
226 - Coro::Timer (independent of Event).
227 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
228
229 0.52 Tue Nov 6 21:36:18 CET 2001
230 - ported to cygwin (trivial).
231 patch by Gerrit P. Haase <gp@familiehaase.de>.
232 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
233
234 0.51 Thu Nov 1 20:39:01 CET 2001
235 - terminate/cancel now work properly (otherwise termination
236 could cause a "next coroutine is not and contains not..."
237 error.
238 - added Coro::Socket::shutdown.
239 - Coro::Event::loop no is the same as Event::loop.
240 - implemented terminate with args + join.
241
242 0.5 Fri Sep 28 16:15:35 CEST 2001
243 - fixed "print" on a Coro::Handle. The print method worked.
244 - small tweaks (seem to reduce memory consumption a lot)
245 in various modules.
246 - splendid use of "no warnings" scattered throughout.
247 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
248
249 0.49 Sun Sep 16 02:42:45 CEST 2001
250 - changed some method calls to function calls for speed
251 inside Coro::Handle.
252 - make Coro::Handle use an array instead of a hash for
253 speed reasons.
254 - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
255 sjlj and ucontext should now work.
256 - IRIX-specific port for libcoro.
257 - swapped order of accept results to match IO::Socket.
258 - changed getsock/peername to sock/peername to match IO::Socket.
259 - fixed a bug that caused segfault when returning to main task
260 under some circumstances.
261 - other bugfixes.
262
263 0.45 Sun Sep 2 02:54:01 CEST 2001
264 - new method Coro::Handle::timeout.
265 - corrected speling of set...name to get...name in Coro::Socket.
266 - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
267 - Coro::Handle now supports fileno and FILENO.
268 - added eg/myhttpd, a web server.
269 - Coro::Socket now accepts numeric ports as well as "port(number)"
270 syntax.
271 - moved some scheduling primitives into xs code. more to come.
272 - new simple priority system.
273 - implemented Coro::Event using XS, almost four times faster!
274 - small memory corruption problem fixed (boy that was difficult).
275
276 0.13 Wed Aug 8 16:53:07 CEST 2001
277 - new method Coro::Handle::readline.
278 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
279 (see eg/lwp on how to make LWP non-blocking).
280 - renamed Coro::Socket::new_inet to new.
281 - added Coro::Util, some utility functions.
282 - die/eval now works better (still get annoying (but true ;)
283 "Callback called exit" messages).
284 - Coro::Handle now supports timeout, and Coro::Socket Timeout.
285 - much better Coro::Socket support.
286
287 0.12 Fri Jul 27 04:19:01 CEST 2001
288 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
289 - very experimental stack sharing algorithm. not 100% safe but
290 should work well in practise ;)
291 - added Coro::RWLock.
292 - Coro::Specific now works.
293
294 0.11 Tue Jul 24 22:49:21 CEST 2001
295 - added specialized hack for newer and older linux versions (fast).
296 - renamed Coro::Event::IO to Coro::Handle.
297 - new module Coro::Socket.
298
299 0.1 Tue Jul 24 01:47:53 CEST 2001
300 - release candidate 3. A rather new internal structure :(
301 - the great renaming: Damian Conway gave me a suitable replacement
302 for yield.
303 - added Coro/libcoro, a portable coroutine implementation for C
304 (not even perl-dependent!!!), which can be used by Coro::State.
305 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
306 perl-5.6.
307 - new function Coro::Event::idle.
308 - the idle process is now overriden
309 by default in Coro::Event.
310 - Coro::Channel now enforces the size.
311 - canceling events now works in all cases.
312 - Coro state now include $_ and $@.
313 - yet another bug workaround that I do not really understand :(
314 - new module Coro::Event::IO (very undocumented) to do
315 non-blocking i/o.
316 - performance tuning.
317
318 0.08 Thu Jul 19 06:13:25 CEST 2001
319 - release candidate 2 (new functionality).
320 - add Coro::State::flush function.
321 - transfer now supports a flags value (mostly for speed ATM).
322 - might compile and work in the presence of threads now.
323 - continuations have a saner syntax.
324 - no more memleaks.
325
326 0.07 Tue Jul 17 17:40:18 CEST 2001
327 - release candidate 1 ;)
328 - slightly nicer code.
329 - fixed a scheduling bug in Coro::Event.
330
331 0.06 Tue Jul 17 04:23:24 CEST 2001
332 - ok, I found the showstopper - the same sub must not be
333 re-entered in two different coroutines, otherwise => crash. I
334 see no easy solution to this problem, except by walking the call
335 chaing and saving/restoring the cv's, which is what I do now.
336 - memory leaks still latent, especially at thread termination.
337 - Coro::Event now works (haha).
338
339 0.05 Sun Jul 15 17:32:20 CEST 2001
340 - fixed a few issues in Coro::Event.
341 - I forgot to include Coro::Event in 0.04 :(:(:(
342
343 0.04 Sun Jul 15 05:24:59 CEST 2001
344 - @_ is now properly localized.
345 - Coro::State is now easier subclassable.
346 - Coro::Cont now coroutine-aware.
347 - Coro::Specific is a low-overhead module to create
348 coroutine-specific vars.
349 - Coro::Event provides a simple interface to Event.
350
351 0.03 Fri Jul 13 14:51:52 CEST 2001
352 - transfer() now implemented in XS (beware).
353 - new module Coro::Cont for really faked continuations.
354 - big internal architecture changes: Coro::State is now
355 really low-level and can thus be used to implement other
356 interesting things, While "Coro::" implements a process-like
357 model. Still crude and subject to change.
358 - $_ and $@ are no longer being localized.
359
360 0.02 Tue Jul 10 01:38:17 CEST 2001
361 - implemented "async" attribute.
362 - $_ and $@ are now localized.
363 - added Coro::Channel.
364 - more testcases, still no docs.
365
366 0.01 Tue Jul 3 02:18:41 CEST 2001
367 - original version; copied from Convert::Scalar.
368
