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