1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: possibly convert some of the Event modules into AnyEvent users.
4
5TODO: eg/lwp to use Coro::Select
6 - should compile with perl 5.9.x now.
7 - reuse PL_start_env for all coros, saves some memory per coroutine.
8 - manage PL_top_env differently, hopefully to avoid panic: top_env.
9 - timeout argument was not properly used in Coro::Socket.
10 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
11 - made Coro::Util an AnyEvent user, moved it to Coro/.
12 - remove "FATAL: uncaught exception" prefix. coroutines that die
13 kill the whole process, just as exceptions in the main coroutine
14 do.
15
162.1 Wed Nov 1 23:01:13 CET 2006
17 - fix a long-standing bug in Coro::Select where select with
18 zero timeout would instead change the current default filehandle.
19 - use a simpler and hopefully more robust way to clone padlists
20 (uses less memory and a perl function instead of our own).
21 - coro can now create a stack guard area on many architectures.
22 - Coro::AIO properly reexports additional functions from IO::AIO.
23 - updated libcoro with a workaround for OS X,
24 pach and testing by Michael Schwern.
25
262.0 Tue Oct 24 05:47:17 CEST 2006
27 - support additional aio requests in Coro::AIO.
28
291.9 (never properly released due to a glitch)
30
311.8 Thu Feb 2 00:59:06 CET 2006
32 - applied suggested patch by SAMV to avoid problems during stupid
33 mark & sweep gc run.
34 - applied patch by Scott Walters for 5.9.3 compatibility.
35
361.7 Tue Dec 27 01:41:58 CET 2005
37 - added Coro::AIO, a thin wrapper around IO::AIO.
38 - improved Makefile.PL explanations.
39
401.6 Mon Dec 12 21:30:05 CET 2005
41 - additionally save PM_curpm might fix as-of-yet
42 unseen problems with regex matches being attributed to the
43 wrong package.
44 - add t/10_bugs.t, which currently checks against imho broken
45 perls that use 0.26MB of stack space per Perl_magic_get
46 invocation (newer linuxes) as opposed to the 0.0002MB perl
47 normally uses.
48 - make stacksize configurable for the ultimate debian experience.
49
501.51 Mon Dec 12 18:48:36 CET 2005
51 - remove debugging warn() accidentally left in Coro::Select.
52
531.5 Tue Nov 29 13:32:44 CET 2005
54 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
55 - fix Coro::Select 'select'.
56 - strict'ify some modules.
57 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
58 - use XSLoader in selected modules.
59 - remove some 5.6 compatibility cruft.
60
611.4 Tue Sep 6 00:11:05 CEST 2005
62 - libcoro did not take into account the trampoline on amd64,
63 when 'l'inux method was used.
64
651.31 Tue Aug 30 23:31:33 CEST 2005
66 - some portability fixes/workarounds.
67
681.3 Sat Aug 20 03:08:56 CEST 2005
69 - no code changes. module seems to work fine.
70 - improve Coro::State docs, remove reference to nonexisting
71 Coro::State::flush method.
72 - no longer autodetect windows, present it as an option instead.
73
741.2 Mon May 16 02:00:55 CEST 2005
75 - included libcoro.c earlier in State.xs, might improve portability.
76 - use a faster and possibly more stable Coro::Cont implementation.
77 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
78 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
79 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
80
811.11 Thu Mar 3 18:00:52 CET 2005
82 - change of contact address.
83
841.1 Tue Feb 22 20:51:16 CET 2005
85 - support [l]inux method on amd64.
86 - allow some context switches while compiling/eval'ing.
87
881.0 Tue Aug 10 03:47:27 CEST 2004
89 - Event 0.89 fixes the bug again.
90 - fix the remaining(??) memleak. I didn't free the cache-AV for
91 padlists, so one AV per created anon-sub leaked.
92
930.97 Fri May 14 15:23:32 CEST 2004
94 - remove stupid gcc extension that was an experiment only anyway.
95
960.96 Thu May 13 18:09:29 CEST 2004
97 - tell people if they have yet another broken Event variant.
98 - made Coro to work _better_ with threads (it seems that, as long
99 as you use Coros in one thread only everything will work fine.
100 Looking at the perl source the problem might be missing locking
101 between Coro and some perl internal routines. That's not easily
102 fixable).
103 - (hopefully) got rid of the static xnext inside transfer.
104
1050.95 Sun Feb 15 03:20:28 CET 2004
106 - removed Coro::State::flush, implemented a new and much
107 faster caching mechanism by attaching magic to the CV.
108 - a memleak with (real) closures remains.
109 - dramatically reduced size of stacks to 65536 (linux/x86), after
110 observing that even myhttpd never had more than a kilobyte
111 of stack in use (stack is still only physically allocated in
112 pagesize increments for systems suporting mmap).
113 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
114 - fix for threaded perl.
115
1160.9 Sun Nov 23 04:32:39 CET 2003
117 - fix a few very hard to track down but (of course) stupid
118 memory leaks.
119 - stringify version number to avoid locale problems :(.
120 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
121 hopefully ignoring it "just works".
122
1230.8 Wed Nov 5 19:38:40 CET 2003
124 - port to perl5.005_03, but only 5.8.x+ is supported!
125 - honor LocalAddr even without LocalPort in Coro::Socket.
126
1270.7 Tue May 27 03:12:38 CEST 2003
128 - the version jump indicates some level of testing, not gobs
129 of new features.
130 - uh... I found the prompt function in ExtUtils::MakeMaker.
131 Highly correct stuff, that is...
132 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
133 the fix is not well understood by the author, so beware :(.
134
1350.652 Thu May 8 02:54:46 CEST 2003
136 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
137 cause version 4 doesn't have ucontext.
138 - Benjamin Reed reported that setjmp works fine on darwin,
139 so preselect it.
140
1410.651 Sat Mar 29 15:00:23 CET 2003
142 - fix a bug in Coro::Handle where some bytes could get lost
143 on reading, reported by jason@nichego.net.
144
1450.65 Sun Mar 23 00:08:26 CET 2003
146 - added a README.linux-glibc.
147 - new module Coro::Select.
148 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
149 (I never claimed that I know what I am doing ;).
150 - set default to setjmp/longjmp on non-x86-linux.
151
1520.6 Thu Nov 21 11:09:06 CET 2002
153 - made lazy context switching the default.
154 - fixed the bug where SemaphoreSet::guard
155 was the same as timed_guard and timed_guard was missing.
156 - fix a memleak in Coro::Timer.
157 - reclassified context sharing as not experimental.
158
1590.534 Sun Apr 14 03:05:12 CEST 2002
160 - fixed backspace => tab in header parsing (myhttpd).
161 - added eg/readline, for elmex.
162 - Coro::Event now calls ->start on first call instead of
163 ->again, which created wrong timeouts for the first ->next.
164 - fixed a bug where Coro::Socket returned a closed socket instead
165 of nothing on ECONNREFUSED and similar error conditions.
166
1670.533 Mon Feb 18 18:49:40 CET 2002
168 - adapt to finally working Event-0.85.
169 - fixed buggy event initialization (trapped under windows, but how
170 could it possibly have worked anywhere?)
171
1720.532 Wed Jan 16 02:45:32 CET 2002
173 - removed the reference to pp_entersub, might work on
174 (some) win32 perls now (testsuite works under cygwin,
175 without Event, which freezes).
176
1770.531 Mon Dec 10 22:18:44 CET 2001
178 - Fixed a bug in SemaphoreSet::timed_down.
179
1800.53 Tue Nov 27 21:11:13 CET 2001
181 - some tests for Event.
182 - slightly different internal architecture to get refcnt into the object
183 and not the reference. might fix a few bugs, certainly did introduce
184 new ones.
185 - Coro::Timer (independent of Event).
186 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
187
1880.52 Tue Nov 6 21:36:18 CET 2001
189 - ported to cygwin (trivial).
190 patch by Gerrit P. Haase <gp@familiehaase.de>.
191 - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
192
1930.51 Thu Nov 1 20:39:01 CET 2001
194 - terminate/cancel now work properly (otherwise termination
195 could cause a "next coroutine is not and contains not..."
196 error.
197 - added Coro::Socket::shutdown.
198 - Coro::Event::loop no is the same as Event::loop.
199 - implemented terminate with args + join.
200
2010.5 Fri Sep 28 16:15:35 CEST 2001
202 - fixed "print" on a Coro::Handle. The print method worked.
203 - small tweaks (seem to reduce memory consumption a lot)
204 in various modules.
205 - splendid use of "no warnings" scattered throughout.
206 - added Coro::Handle::rbuf, fixed Coro::Handle::fh.
207
2080.49 Sun Sep 16 02:42:45 CEST 2001
209 - changed some method calls to function calls for speed
210 inside Coro::Handle.
211 - make Coro::Handle use an array instead of a hash for
212 speed reasons.
213 - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
214 sjlj and ucontext should now work.
215 - IRIX-specific port for libcoro.
216 - swapped order of accept results to match IO::Socket.
217 - changed getsock/peername to sock/peername to match IO::Socket.
218 - fixed a bug that caused segfault when returning to main task
219 under some circumstances.
220 - other bugfixes.
221
2220.45 Sun Sep 2 02:54:01 CEST 2001
223 - new method Coro::Handle::timeout.
224 - corrected speling of set...name to get...name in Coro::Socket.
225 - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
226 - Coro::Handle now supports fileno and FILENO.
227 - added eg/myhttpd, a web server.
228 - Coro::Socket now accepts numeric ports as well as "port(number)"
229 syntax.
230 - moved some scheduling primitives into xs code. more to come.
231 - new simple priority system.
232 - implemented Coro::Event using XS, almost four times faster!
233 - small memory corruption problem fixed (boy that was difficult).
234
2350.13 Wed Aug 8 16:53:07 CEST 2001
236 - new method Coro::Handle::readline.
237 - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
238 (see eg/lwp on how to make LWP non-blocking).
239 - renamed Coro::Socket::new_inet to new.
240 - added Coro::Util, some utility functions.
241 - die/eval now works better (still get annoying (but true ;)
242 "Callback called exit" messages).
243 - Coro::Handle now supports timeout, and Coro::Socket Timeout.
244 - much better Coro::Socket support.
245
2460.12 Fri Jul 27 04:19:01 CEST 2001
247 - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
248 - very experimental stack sharing algorithm. not 100% safe but
249 should work well in practise ;)
250 - added Coro::RWLock.
251 - Coro::Specific now works.
252
2530.11 Tue Jul 24 22:49:21 CEST 2001
254 - added specialized hack for newer and older linux versions (fast).
255 - renamed Coro::Event::IO to Coro::Handle.
256 - new module Coro::Socket.
257
2580.1 Tue Jul 24 01:47:53 CEST 2001
259 - release candidate 3. A rather new internal structure :(
260 - the great renaming: Damian Conway gave me a suitable replacement
261 for yield.
262 - added Coro/libcoro, a portable coroutine implementation for C
263 (not even perl-dependent!!!), which can be used by Coro::State.
264 - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
265 perl-5.6.
3 - new function Coro::Event::idle. 266 - new function Coro::Event::idle.
4 - the idle process is now overriden 267 - the idle process is now overriden
5 by default in Coro::Event. 268 by default in Coro::Event.

274 non-blocking i/o.
275 - performance tuning.
