# User Rev Content
1 root 1.1 Revision history for Perl extension Coro.
2 root 1.113
3 root 1.169 TODO: transfer flags must be per state
4    
5 root 1.160 3.0
6 root 1.163 - the "FINALLY COMPLETELY STABLE" release (coming soon:
7     the "FAMOUS LAST WORDS" release).
8 root 1.166 - implement a new stack sharing algorithm, which uses a stack
9     pool (size currently hardcoded).
10 root 1.155 - make stack sharing mandatory (it no longer uses a heuristic).
11 root 1.157 - eval/die no longer cause weird problems under heavy use.
12 root 1.152 - Coro::Event could cause livelocks if it was used but
13 root 1.161 no Coro::Event watchers were used.
14 root 1.167 - Coro::Event now uses asynccheck as prepare does not
15     check for changed watchers.
16 root 1.152 - Coro::Event should be cleaner and more efficient now.
17 root 1.165 - new utility function Coro::unblock_sub.
18 root 1.164 - document the sad fact that Event is no longer reentrant.
19 root 1.163 - putting a coroutine into the ready queue twice could under
20     some circumstances lead to stack corruption.
21 root 1.161 - minor incompatibility: subclassing Coro::State is supported
22     directly now without going through a _coro_state member.
23 root 1.156 - state/coro switching is much faster now.
24 root 1.154 - very minor optimisations and code/documentation cleanup.
25 root 1.153 - avoid problems due to compiler inlining.
26 root 1.154 - removed timers from Coro::Timer -> use AnyEvent instead.
27     - replaced Coro::idle coroutine by (cleaner) idle handler.
28 root 1.156 - updated to newest libcoro.
29 root 1.159 - implement enhanced support for valgrind.
30 root 1.162 - implement is_ready and return value for ready.
31 root 1.168 - removed Coro::Cont, it was a misnomer (it's generators),
32     and it was somewhat annoying to get it right. Will come back
33     if somebody asks for it :)
34 root 1.163 - many ->wait methods and Coro::Event could return
35     spuriously without the event having happened.
36 root 1.146
37 root 1.145 2.5 Tue Nov 7 12:22:33 CET 2006
38 root 1.143 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
39     use AnyEvent, moved them to Coro/.
40 root 1.140 - added Coro::LWP which contains all the uglyness required to
41     make LWP non-blocking.
42     - should work with perl 5.9.x now (Andreas König made me do it).
43 root 1.141 - fixed another bug in Coro::Select when the timeout was undef.
44 root 1.136 - reuse PL_start_env for all coros, saves some memory per coroutine.
45     - manage PL_top_env differently, hopefully to avoid panic: top_env.
46 root 1.137 - timeout argument was not properly used in Coro::Socket.
47     - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
48 root 1.138 - emulate undocumented(!) functionality of IO::Socket required
49     by LWP(!!).
50     - updated eg/lwp to work with newer lwp's.
51 root 1.140 - remove "FATAL: uncaught exception" prefix. Coroutines that die
52     kill the whole process, just as exceptions in the main "coroutine"
53     did already.
54 root 1.135
55 root 1.134 2.1 Wed Nov 1 23:01:13 CET 2006
56     - fix a long-standing bug in Coro::Select where select with
57     zero timeout would instead change the current default filehandle.
58 root 1.132 - use a simpler and hopefully more robust way to clone padlists
59     (uses less memory and a perl function instead of our own).
60     - coro can now create a stack guard area on many architectures.
61 root 1.134 - Coro::AIO properly reexports additional functions from IO::AIO.
62 root 1.132 - updated libcoro with a workaround for OS X,
63 root 1.134 pach and testing by Michael Schwern.
64 root 1.130
65 root 1.129 2.0 Tue Oct 24 05:47:17 CEST 2006
66 root 1.128 - support additional aio requests in Coro::AIO.
67    
68 root 1.129 1.9 (never properly released due to a glitch)
69    
70 root 1.127 1.8 Thu Feb 2 00:59:06 CET 2006
71 root 1.125 - applied suggested patch by SAMV to avoid problems during stupid
72     mark & sweep gc run.
73 root 1.126 - applied patch by Scott Walters for 5.9.3 compatibility.
74 root 1.125
75 root 1.124 1.7 Tue Dec 27 01:41:58 CET 2005
76 root 1.123 - added Coro::AIO, a thin wrapper around IO::AIO.
77 root 1.122 - improved Makefile.PL explanations.
78    
79 root 1.119 1.6 Mon Dec 12 21:30:05 CET 2005
80 root 1.117 - additionally save PM_curpm might fix as-of-yet
81 root 1.121 unseen problems with regex matches being attributed to the
82 root 1.117 wrong package.
83 root 1.118 - add t/10_bugs.t, which currently checks against imho broken
84     perls that use 0.26MB of stack space per Perl_magic_get
85 root 1.121 invocation (newer linuxes) as opposed to the 0.0002MB perl
86     normally uses.
87 root 1.120 - make stacksize configurable for the ultimate debian experience.
88 root 1.117
89 root 1.116 1.51 Mon Dec 12 18:48:36 CET 2005

91    
92 root 1.115 1.5 Tue Nov 29 13:32:44 CET 2005
93 root 1.114 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
94 root 1.115 - fix Coro::Select 'select'.
95     - strict'ify some modules.
96 root 1.112 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
97 root 1.115 - use XSLoader in selected modules.
98     - remove some 5.6 compatibility cruft.
99 root 1.112
100 root 1.111 1.4 Tue Sep 6 00:11:05 CEST 2005
101     - libcoro did not take into account the trampoline on amd64,
102     when 'l'inux method was used.

105     - some portability fixes/workarounds.
106    
107 root 1.107 1.3 Sat Aug 20 03:08:56 CEST 2005
108 root 1.108 - no code changes. module seems to work fine.
109 root 1.106 - improve Coro::State docs, remove reference to nonexisting
110     Coro::State::flush method.
111 root 1.107 - no longer autodetect windows, present it as an option instead.

113 root 1.105 1.2 Mon May 16 02:00:55 CEST 2005
114 root 1.100 - included libcoro.c earlier in State.xs, might improve portability.
115 root 1.101 - use a faster and possibly more stable Coro::Cont implementation.
116 root 1.102 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
117 root 1.104 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.

119 root 1.100
120 root 1.99 1.11 Thu Mar 3 18:00:52 CET 2005
121     - change of contact address.
122    
123 root 1.98 1.1 Tue Feb 22 20:51:16 CET 2005
124 root 1.97 - support [l]inux method on amd64.
125 root 1.109 - allow some context switches while compiling/eval'ing.
126 root 1.97
127 root 1.96 1.0 Tue Aug 10 03:47:27 CEST 2004
128 root 1.95 - Event 0.89 fixes the bug again.
129 root 1.96 - fix the remaining(??) memleak. I didn't free the cache-AV for
130     padlists, so one AV per created anon-sub leaked.
131 root 1.95
132 pcg 1.94 0.97 Fri May 14 15:23:32 CEST 2004
133     - remove stupid gcc extension that was an experiment only anyway.
134    
135 pcg 1.93 0.96 Thu May 13 18:09:29 CEST 2004
136 root 1.103 - tell people if they have yet another broken Event variant.
137 pcg 1.91 - made Coro to work _better_ with threads (it seems that, as long
138     as you use Coros in one thread only everything will work fine.
139     Looking at the perl source the problem might be missing locking
140     between Coro and some perl internal routines. That's not easily
141     fixable).
142 pcg 1.92 - (hopefully) got rid of the static xnext inside transfer.
143 pcg 1.91
144 pcg 1.90 0.95 Sun Feb 15 03:20:28 CET 2004
145 pcg 1.86 - removed Coro::State::flush, implemented a new and much
146     faster caching mechanism by attaching magic to the CV.
147 pcg 1.87 - a memleak with (real) closures remains.
148 pcg 1.88 - dramatically reduced size of stacks to 65536 (linux/x86), after
149     observing that even myhttpd never had more than a kilobyte
150     of stack in use (stack is still only physically allocated in
151     pagesize increments for systems suporting mmap).
152 pcg 1.89 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
153 pcg 1.90 - fix for threaded perl.
154 pcg 1.86
155 pcg 1.85 0.9 Sun Nov 23 04:32:39 CET 2003
156 pcg 1.84 - fix a few very hard to track down but (of course) stupid
157     memory leaks.
158     - stringify version number to avoid locale problems :(.
159 pcg 1.85 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
160     hopefully ignoring it "just works".
161 pcg 1.84
162 pcg 1.83 0.8 Wed Nov 5 19:38:40 CET 2003
163     - port to perl5.005_03, but only 5.8.x+ is supported!
164 pcg 1.82 - honor LocalAddr even without LocalPort in Coro::Socket.
165    
166 root 1.81 0.7 Tue May 27 03:12:38 CEST 2003
167     - the version jump indicates some level of testing, not gobs
168     of new features.
169 root 1.80 - uh... I found the prompt function in ExtUtils::MakeMaker.
170     Highly correct stuff, that is...
171 root 1.81 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
172     the fix is not well understood by the author, so beware :(.
173 root 1.80
174 root 1.79 0.652 Thu May 8 02:54:46 CEST 2003
175 root 1.76 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
176 root 1.78 cause version 4 doesn't have ucontext.
177 root 1.77 - Benjamin Reed reported that setjmp works fine on darwin,
178     so preselect it.
179 root 1.76
180 root 1.75 0.651 Sat Mar 29 15:00:23 CET 2003
181     - fix a bug in Coro::Handle where some bytes could get lost
182     on reading, reported by jason@nichego.net.
183 root 1.74
184 root 1.73 0.65 Sun Mar 23 00:08:26 CET 2003
185 root 1.72 - added a README.linux-glibc.
186     - new module Coro::Select.
187     - also save/restore PL_comppad, fixes segfaults with 5.8.1.
188     (I never claimed that I know what I am doing ;).
189 root 1.73 - set default to setjmp/longjmp on non-x86-linux.
190 root 1.72
191 root 1.71 0.6 Thu Nov 21 11:09:06 CET 2002
192     - made lazy context switching the default.
193     - fixed the bug where SemaphoreSet::guard
194     was the same as timed_guard and timed_guard was missing.
195     - fix a memleak in Coro::Timer.
196     - reclassified context sharing as not experimental.
197    
198 root 1.70 0.534 Sun Apr 14 03:05:12 CEST 2002
199 root 1.69 - fixed backspace => tab in header parsing (myhttpd).
200 root 1.70 - added eg/readline, for elmex.
201     - Coro::Event now calls ->start on first call instead of
202     ->again, which created wrong timeouts for the first ->next.
203     - fixed a bug where Coro::Socket returned a closed socket instead
204     of nothing on ECONNREFUSED and similar error conditions.
205 root 1.69
206 root 1.68 0.533 Mon Feb 18 18:49:40 CET 2002
207     - adapt to finally working Event-0.85.
208     - fixed buggy event initialization (trapped under windows, but how
209     could it possibly have worked anywhere?)
210    
211 root 1.67 0.532 Wed Jan 16 02:45:32 CET 2002
212 root 1.66 - removed the reference to pp_entersub, might work on
213     (some) win32 perls now (testsuite works under cygwin,
214     without Event, which freezes).
215 root 1.65
216 root 1.64 0.531 Mon Dec 10 22:18:44 CET 2001
217 root 1.63 - Fixed a bug in SemaphoreSet::timed_down.

220 root 1.60 - some tests for Event.
221 root 1.61 - slightly different internal architecture to get refcnt into the object
222     and not the reference. might fix a few bugs, certainly did introduce
223     new ones.
224     - Coro::Timer (independent of Event).
225 root 1.62 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
226 root 1.60
227 root 1.64 0.52 Tue Nov 6 21:36:18 CET 2001
228 root 1.58 - ported to cygwin (trivial).
229     patch by Gerrit P. Haase <gp@familiehaase.de>.
230     - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
231    
232 root 1.64 0.51 Thu Nov 1 20:39:01 CET 2001
233 root 1.54 - terminate/cancel now work properly (otherwise termination
234     could cause a "next coroutine is not and contains not..."
235     error.
236 root 1.55 - added Coro::Socket::shutdown.
237 root 1.56 - Coro::Event::loop no is the same as Event::loop.
238     - implemented terminate with args + join.
239 root 1.54
240 root 1.64 0.5 Fri Sep 28 16:15:35 CEST 2001
241 root 1.53 - fixed "print" on a Coro::Handle. The print method worked.
242 root 1.50 - small tweaks (seem to reduce memory consumption a lot)
243     in various modules.
244     - splendid use of "no warnings" scattered throughout.
245 root 1.52 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
246 root 1.48
247 root 1.47 0.49 Sun Sep 16 02:42:45 CEST 2001
248 root 1.43 - changed some method calls to function calls for speed
249     inside Coro::Handle.
250 root 1.44 - make Coro::Handle use an array instead of a hash for
251     speed reasons.
252     - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
253     sjlj and ucontext should now work.
254     - IRIX-specific port for libcoro.
255 root 1.45 - swapped order of accept results to match IO::Socket.
256 root 1.46 - changed getsock/peername to sock/peername to match IO::Socket.
257     - fixed a bug that caused segfault when returning to main task
258     under some circumstances.
259     - other bugfixes.
260 root 1.43
261 root 1.42 0.45 Sun Sep 2 02:54:01 CEST 2001
262 root 1.36 - new method Coro::Handle::timeout.

264     - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
265     - Coro::Handle now supports fileno and FILENO.
266     - added eg/myhttpd, a web server.
267 root 1.37 - Coro::Socket now accepts numeric ports as well as "port(number)"
268     syntax.
269 root 1.38 - moved some scheduling primitives into xs code. more to come.
270 root 1.39 - new simple priority system.
271 root 1.40 - implemented Coro::Event using XS, almost four times faster!
272 root 1.41 - small memory corruption problem fixed (boy that was difficult).
273 root 1.36
274 root 1.35 0.13 Wed Aug 8 16:53:07 CEST 2001
275 root 1.31 - new method Coro::Handle::readline.
276 root 1.34 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
277     (see eg/lwp on how to make LWP non-blocking).
278 root 1.31 - renamed Coro::Socket::new_inet to new.
279 root 1.32 - added Coro::Util, some utility functions.
280 root 1.33 - die/eval now works better (still get annoying (but true ;)
281     "Callback called exit" messages).
282 root 1.34 - Coro::Handle now supports timeout, and Coro::Socket Timeout.
283     - much better Coro::Socket support.
284 root 1.31
285     0.12 Fri Jul 27 04:19:01 CEST 2001
286 root 1.29 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
287 root 1.34 - very experimental stack sharing algorithm. not 100% safe but
288 root 1.28 should work well in practise ;)
289 root 1.30 - added Coro::RWLock.
290 root 1.31 - Coro::Specific now works.
291 root 1.28
292     0.11 Tue Jul 24 22:49:21 CEST 2001
293 root 1.27 - added specialized hack for newer and older linux versions (fast).
294     - renamed Coro::Event::IO to Coro::Handle.
295     - new module Coro::Socket.
296    
297 root 1.26 0.1 Tue Jul 24 01:47:53 CEST 2001
298 root 1.23 - release candidate 3. A rather new internal structure :(
299 root 1.24 - the great renaming: Damian Conway gave me a suitable replacement
300     for yield.
301 root 1.23 - added Coro/libcoro, a portable coroutine implementation for C
302 root 1.22 (not even perl-dependent!!!), which can be used by Coro::State.
303 root 1.20 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
304     perl-5.6.
305 root 1.16 - new function Coro::Event::idle.
306     - the idle process is now overriden
307     by default in Coro::Event.

309 root 1.18 - canceling events now works in all cases.
310 root 1.19 - Coro state now include $_ and $@.
311     - yet another bug workaround that I do not really understand :(
312 root 1.21 - new module Coro::Event::IO (very undocumented) to do
313     non-blocking i/o.
314 root 1.25 - performance tuning.
315 root 1.16
316 root 1.15 0.08 Thu Jul 19 06:13:25 CEST 2001
317 root 1.14 - release candidate 2 (new functionality).
318 root 1.13 - add Coro::State::flush function.
319     - transfer now supports a flags value (mostly for speed ATM).
320     - might compile and work in the presence of threads now.
321 root 1.14 - continuations have a saner syntax.
322 root 1.19 - no more memleaks.
323 root 1.13
324 root 1.12 0.07 Tue Jul 17 17:40:18 CEST 2001
325     - release candidate 1 ;)
326     - slightly nicer code.
327     - fixed a scheduling bug in Coro::Event.
328    
329 root 1.11 0.06 Tue Jul 17 04:23:24 CEST 2001
330     - ok, I found the showstopper - the same sub must not be
331 root 1.9 re-entered in two different coroutines, otherwise => crash. I
332     see no easy solution to this problem, except by walking the call
333     chaing and saving/restoring the cv's, which is what I do now.
334 root 1.11 - memory leaks still latent, especially at thread termination.
335     - Coro::Event now works (haha).
336 root 1.9
337 root 1.8 0.05 Sun Jul 15 17:32:20 CEST 2001
338     - fixed a few issues in Coro::Event.
339     - I forgot to include Coro::Event in 0.04 :(:(:(
340    
341 root 1.7 0.04 Sun Jul 15 05:24:59 CEST 2001
342 root 1.5 - @_ is now properly localized.
343 root 1.4 - Coro::State is now easier subclassable.
344     - Coro::Cont now coroutine-aware.
345     - Coro::Specific is a low-overhead module to create
346     coroutine-specific vars.
347 root 1.6 - Coro::Event provides a simple interface to Event.
348 root 1.4
349 root 1.3 0.03 Fri Jul 13 14:51:52 CEST 2001
350 root 1.4 - transfer() now implemented in XS (beware).
351     - new module Coro::Cont for really faked continuations.
352     - big internal architecture changes: Coro::State is now
353 root 1.3 really low-level and can thus be used to implement other
354 root 1.4 interesting things, While "Coro::" implements a process-like
355     model. Still crude and subject to change.
356 root 1.3 - $_ and $@ are no longer being localized.
357    
358 root 1.2 0.02 Tue Jul 10 01:38:17 CEST 2001
