1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
30.53 3TODO: check wether stack-sharing is still effective
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines?
5TODO: verify exception frame changes and force stack copies?
6
7 - reimplement a new stack sharing algorithm.
8 - make stack sharing mandatory (it no longer uses a heuristic).
9 - Coro::Event could cause livelocks if it was used but
10 Event watchers were used directly.
11 - Coro::Event should be cleaner and more efficient now.
12 - minor incompatibility: subclassing is supported directly now
13 without going through a _coro_state member.
14 - state/coro switching is much faster now.
15 - very minor optimisations and code/documentation cleanup.
16 - avoid problems due to compiler inlining.
17 - removed timers from Coro::Timer -> use AnyEvent instead.
18 - replaced Coro::idle coroutine by (cleaner) idle handler.
19 - updated to newest libcoro.
20
212.5 Tue Nov 7 12:22:33 CET 2006
22 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
23 use AnyEvent, moved them to Coro/.
24 - added Coro::LWP which contains all the uglyness required to
25 make LWP non-blocking.
26 - should work with perl 5.9.x now (Andreas König made me do it).
27 - fixed another bug in Coro::Select when the timeout was undef.
28 - reuse PL_start_env for all coros, saves some memory per coroutine.
29 - manage PL_top_env differently, hopefully to avoid panic: top_env.
30 - timeout argument was not properly used in Coro::Socket.
31 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
32 - emulate undocumented(!) functionality of IO::Socket required
33 by LWP(!!).
34 - updated eg/lwp to work with newer lwp's.
35 - remove "FATAL: uncaught exception" prefix. Coroutines that die
36 kill the whole process, just as exceptions in the main "coroutine"
37 did already.
38
392.1 Wed Nov 1 23:01:13 CET 2006
40 - fix a long-standing bug in Coro::Select where select with
41 zero timeout would instead change the current default filehandle.
42 - use a simpler and hopefully more robust way to clone padlists
43 (uses less memory and a perl function instead of our own).
44 - coro can now create a stack guard area on many architectures.
45 - Coro::AIO properly reexports additional functions from IO::AIO.
46 - updated libcoro with a workaround for OS X,
47 pach and testing by Michael Schwern.
48
492.0 Tue Oct 24 05:47:17 CEST 2006
50 - support additional aio requests in Coro::AIO.
51
521.9 (never properly released due to a glitch)
53
541.8 Thu Feb 2 00:59:06 CET 2006
55 - applied suggested patch by SAMV to avoid problems during stupid
56 mark & sweep gc run.
57 - applied patch by Scott Walters for 5.9.3 compatibility.
58
591.7 Tue Dec 27 01:41:58 CET 2005
60 - added Coro::AIO, a thin wrapper around IO::AIO.
61 - improved Makefile.PL explanations.
62
631.6 Mon Dec 12 21:30:05 CET 2005
64 - additionally save PM_curpm might fix as-of-yet
65 unseen problems with regex matches being attributed to the
66 wrong package.
67 - add t/10_bugs.t, which currently checks against imho broken
68 perls that use 0.26MB of stack space per Perl_magic_get
69 invocation (newer linuxes) as opposed to the 0.0002MB perl
70 normally uses.
71 - make stacksize configurable for the ultimate debian experience.
72
731.51 Mon Dec 12 18:48:36 CET 2005
74 - remove debugging warn() accidentally left in Coro::Select.
75
761.5 Tue Nov 29 13:32:44 CET 2005
77 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
78 - fix Coro::Select 'select'.
79 - strict'ify some modules.
80 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
81 - use XSLoader in selected modules.
82 - remove some 5.6 compatibility cruft.
83
841.4 Tue Sep 6 00:11:05 CEST 2005
85 - libcoro did not take into account the trampoline on amd64,
86 when 'l'inux method was used.
87
881.31 Tue Aug 30 23:31:33 CEST 2005
89 - some portability fixes/workarounds.
90
911.3 Sat Aug 20 03:08:56 CEST 2005
92 - no code changes. module seems to work fine.
93 - improve Coro::State docs, remove reference to nonexisting
94 Coro::State::flush method.
95 - no longer autodetect windows, present it as an option instead.
96
971.2 Mon May 16 02:00:55 CEST 2005
98 - included libcoro.c earlier in State.xs, might improve portability.
99 - use a faster and possibly more stable Coro::Cont implementation.
100 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
101 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
102 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
103
1041.11 Thu Mar 3 18:00:52 CET 2005
105 - change of contact address.
106
1071.1 Tue Feb 22 20:51:16 CET 2005
108 - support [l]inux method on amd64.
109 - allow some context switches while compiling/eval'ing.
110
1111.0 Tue Aug 10 03:47:27 CEST 2004
112 - Event 0.89 fixes the bug again.
113 - fix the remaining(??) memleak. I didn't free the cache-AV for
114 padlists, so one AV per created anon-sub leaked.
115
1160.97 Fri May 14 15:23:32 CEST 2004
117 - remove stupid gcc extension that was an experiment only anyway.
118
1190.96 Thu May 13 18:09:29 CEST 2004
120 - tell people if they have yet another broken Event variant.
121 - made Coro to work _better_ with threads (it seems that, as long
122 as you use Coros in one thread only everything will work fine.
123 Looking at the perl source the problem might be missing locking
124 between Coro and some perl internal routines. That's not easily
125 fixable).
126 - (hopefully) got rid of the static xnext inside transfer.
127
1280.95 Sun Feb 15 03:20:28 CET 2004
129 - removed Coro::State::flush, implemented a new and much
130 faster caching mechanism by attaching magic to the CV.
131 - a memleak with (real) closures remains.
132 - dramatically reduced size of stacks to 65536 (linux/x86), after
133 observing that even myhttpd never had more than a kilobyte
134 of stack in use (stack is still only physically allocated in
135 pagesize increments for systems suporting mmap).
136 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
137 - fix for threaded perl.
138
1390.9 Sun Nov 23 04:32:39 CET 2003
140 - fix a few very hard to track down but (of course) stupid
141 memory leaks.
142 - stringify version number to avoid locale problems :(.
143 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
144 hopefully ignoring it "just works".
145
1460.8 Wed Nov 5 19:38:40 CET 2003
147 - port to perl5.005_03, but only 5.8.x+ is supported!
148 - honor LocalAddr even without LocalPort in Coro::Socket.
149
1500.7 Tue May 27 03:12:38 CEST 2003
151 - the version jump indicates some level of testing, not gobs
152 of new features.
153 - uh... I found the prompt function in ExtUtils::MakeMaker.
154 Highly correct stuff, that is...
155 - fixed(?) a bug with die's in coroutines causing "panic: top_env".
156 the fix is not well understood by the author, so beware :(.
157
1580.652 Thu May 8 02:54:46 CEST 2003
159 - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
160 cause version 4 doesn't have ucontext.
161 - Benjamin Reed reported that setjmp works fine on darwin,
162 so preselect it.
163
1640.651 Sat Mar 29 15:00:23 CET 2003
165 - fix a bug in Coro::Handle where some bytes could get lost
166 on reading, reported by jason@nichego.net.
167
1680.65 Sun Mar 23 00:08:26 CET 2003
169 - added a README.linux-glibc.
170 - new module Coro::Select.
171 - also save/restore PL_comppad, fixes segfaults with 5.8.1.
172 (I never claimed that I know what I am doing ;).
173 - set default to setjmp/longjmp on non-x86-linux.
174
1750.6 Thu Nov 21 11:09:06 CET 2002
176 - made lazy context switching the default.
177 - fixed the bug where SemaphoreSet::guard
178 was the same as timed_guard and timed_guard was missing.
179 - fix a memleak in Coro::Timer.
180 - reclassified context sharing as not experimental.
181
1820.534 Sun Apr 14 03:05:12 CEST 2002
183 - fixed backspace => tab in header parsing (myhttpd).
184 - added eg/readline, for elmex.
185 - Coro::Event now calls ->start on first call instead of
186 ->again, which created wrong timeouts for the first ->next.
187 - fixed a bug where Coro::Socket returned a closed socket instead
188 of nothing on ECONNREFUSED and similar error conditions.
189
1900.533 Mon Feb 18 18:49:40 CET 2002
191 - adapt to finally working Event-0.85.
192 - fixed buggy event initialization (trapped under windows, but how
193 could it possibly have worked anywhere?)
194
1950.532 Wed Jan 16 02:45:32 CET 2002
196 - removed the reference to pp_entersub, might work on
197 (some) win32 perls now (testsuite works under cygwin,
198 without Event, which freezes).
199
2000.531 Mon Dec 10 22:18:44 CET 2001
201 - Fixed a bug in SemaphoreSet::timed_down.
202

5 - slightly different internal architecture to get refcnt into the object 205 - slightly different internal architecture to get refcnt into the object
6 and not the reference. might fix a few bugs, certainly did introduce 206 and not the reference. might fix a few bugs, certainly did introduce
7 new ones. 207 new ones.
8 - Coro::Timer (independent of Event). 208 - Coro::Timer (independent of Event).
209 - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
