|
|
8 | - minor cleanups. |
|
|
9 | - use much larger stacks on linux and perl < 5.8.8. |
|
|
10 | - Coro::Debug::new_unix_server did not unlink the socket |
|
|
11 | when destroyed. |
|
|

|
|
13 | 4.911 Tue Nov 11 04:26:17 CET 2008 |
|
|
14 | - "port" to threaded perls. |
|
|
15 | |
|
|
16 | 4.91 Mon Nov 10 05:36:38 CET 2008 |
|
|
17 | - the ->throw exception object no longer leaks. |
|
|
18 | - creating a new cctx leaked a scopestack entry (memleak). |
|
|
19 | - new coroutines didn't get created with a zero flags field |
|
|
20 | (unknown impact). |
|
|
21 | - calling ->throw on a not-yet-started coroutine should now work |
|
|
22 | instead of being ignored. |
|
|
23 | - ->throw is now supported on Coro::State objects. |
|
|
24 | - clean up cctx creation code a bit. |
|
|
25 | - entersub is actually a UNOP, not a LOGOP (not a bugfix). |
|
|
26 | |
|
|
27 | 4.9 Sat Nov 8 17:45:27 CET 2008 |
|
|
28 | - (libcoro) did not preserve rbp with CORO_ASM (we are getting there). |
|
|
29 | - (libcoro) no longer leak threads in the experimental pthread backend, |
|
|
30 | also speed it up considerably. |
|
|
31 | - (libcoro) do not rely on makecontext passing void *'s unscathed. |
|
|
32 | - fix compiletime dependencies on libcoro in the Makefile. |
|
|
33 | - cctx_count wasn't always updated properly. |
|
|
34 | - Coro::State::cctx_stacksize wasn't applied correctly. |
|
|
35 | - new function Coro::State::cctx_max_idle. |
|
|
36 | - the default max number of idle C contexts is now 4. |
|
|
37 | - (libcoro) try harder to get _setjmp/_longjmp. |
|
|
38 | - (libcoro) cleanup and extend the libcoro API to officially |
|
|
39 | allow the creation of empty source contexts. |
|
|
40 | - very experimental workaround for the totally broken netbsd platform. |
|
|
41 | - tried to hack around openbsd bugs. |
|
|
42 | |
|
|
43 | 4.804 Wed Nov 5 16:36:00 CET 2008 |
|
|
44 | - Coro::Debug::new_unix_server would not create a non-blocking listening |
|
|
45 | socket, sometimes causing freezes. |
|
|
46 | - (libcoro) fix misaligned stack points for setjmp and assembly |
|
|
47 | methods, which can cause crashes on x86/x86_64 with a sufficiently |
|
|
48 | aggressive compiler. |
|
|
49 | - new function: Coro::Debug::new_tcp_server. |
|
|
50 | - move ->throw into the Coro class because it only works on coro objects. |
|
|
51 | |
|
|
52 | 4.803 Mon Nov 3 17:16:12 CET 2008 |
|
|
53 | - (libcoro) use a global asm statement to become independent of gcc |
|
|
54 | otpimisations for CORO_ASM (thanks to pippijn for the idea). |
|
|
55 | - try to workaround yet another broken bsd, this time dragonfly. |
|
|
56 | |
|
|
57 | 4.802 Thu Oct 30 10:56:12 CET 2008 |
|
|
58 | - support -fno-omit-frame-pointer on x86 with the assembly method. |
|
|
59 | - tune 01_unblock.t tests a bit. |
|
|
60 | |
|
|
61 | 4.801 Wed Oct 22 18:33:37 CEST 2008 |
|
|
62 | - improve readline speed for very long "lines". |
|
|
63 | - backport to 5.8.8. |
|
|
64 | |
|
|
65 | 4.8 Thu Oct 2 13:34:40 CEST 2008 |
|
|
66 | - new function Coro::AIO::aio_wait. |
|
|
67 | - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent". |
|
|
68 | - greatly speed up and reduce memory usage of Coro::AIO requests. |
|
|
69 | - implement some other ยต-optimisations. |
|
|
70 | |
|
|
71 | 4.749 Mon Sep 29 14:40:12 CEST 2008 |
|
|
72 | - port to slow and broken pseudo-threaded perls. (courtesy pippijn). |
|
|
73 | |
|
|
74 | 4.748 Sat Sep 27 14:03:19 CEST 2008 |
|
|
75 | - implement, but do not document, PerlIO::cede(granularity). |
|
|
76 | - Coro::Storable forgot to wrap Storable::pstore. |
|
|
77 | - work around the multitude of leaks and memory corruption |
|
|
78 | bugs in PerlIO::via by using our own C-level perliol. As a side |
|
|
79 | effect, Coro::Storable is now much, much, much faster. |
|
|
80 | |
|
|
81 | 4.747 Tue Sep 23 01:59:41 CEST 2008 |
|
|
82 | - fix a per-cv memleak (one empty array was leaked per |
|
|
83 | code reference). |
|
|
84 | - avoid a crash in coro->call|rss when the coroutine was already |
|
|
85 | destroyed (most noticably when using Coro::Debug::ps :) |
|
|
86 | - also protect *Storable::FILE. |
|
|
87 | - push up default storable granularity to 20ms. |
|
|
88 | |
|
|
89 | 4.746 Sun Sep 21 03:22:20 CEST 2008 |
|
|
90 | - be more insistent on locking Storable against reentrancy |
|
|
91 | in Coro::Storable. |
|
|
92 | - move swap_def?v and throw to Coro::State, as documented. |
|
|
93 | |
|
|
94 | 4.745 Thu Jul 24 00:14:38 CEST 2008 |
|
|
95 | - remove debugging code related to MgPV_nolen_const, also try to |
|
|
96 | make it compile with perl 5.8.6 (yes, apple apparently loves |
|
|
97 | outdated software). Reported by John S. |
|
|
98 | |
|
|
99 | 4.744 Tue Jul 8 22:06:35 CEST 2008 |
|
|
100 | - correctly provide default DIE/WARN handlers as documented. |
|
|
101 | - also overwrite PL_vtbl_sigelem.svt_clear, even though current |
|
|
102 | implementations inside perl work fine for us. |
|
|
103 | |
|
|
104 | 4.743 Mon Jun 16 00:21:57 CEST 2008 |
|
|
105 | - when using Coro::EV without running EV::loop it could |
|
|
106 | result in busy-waiting for events, this has been fixed. |
|
|
107 | - reduce codesize and improve performance by using EV_DEFAULT_UC. |
|
|
108 | |
|
|
109 | 4.742 Sat May 31 14:10:21 CEST 2008 |
|
|
110 | - implement a workaround for (some) perl <5.8.8 versions. |
|
|
111 | - require EV 3.3+. |
|
|
112 | |
|
|
113 | 4.741 Fri May 30 23:33:09 CEST 2008 |
|
|
114 | - tell netbsd how utterly broken their imitation of an OS is |
|
|
115 | and refuse to build by default if pthreads are in use. |
|
|
116 | - switch to "s" method on all bsd's by default, as their ucontext |
|
|
117 | stuff seems just too broken. |
|
|
118 | - fix a bug in Coro::Select. |
|
|
119 | |
|
|
120 | 4.74 Thu May 29 20:05:31 CEST 2008 |
|
|
121 | - do not test Coro::LWP for lack of dependencies. |
|
|
122 | - do not test Coro::Select for lack of working perls. |
|
|
123 | |
|
|
124 | 4.73 Thu May 29 2008 |
|
|
125 | - fix a bug in Coro::EV which would cause it to block despite |
|
|
126 | there being runnable coroutines. |
|
|
127 | - sprinkle "no warnings" freely over everything, also suppress |
|
|
128 | warnings for some other modules. |
|
|
129 | - fix typo in WSAEWOULDBLOCK. |
|
|
130 | |
|
|
131 | 4.72 Sun May 25 05:14:36 CEST 2008 |
|
|
132 | - tweak META.yaml a bit, unfortunately, there is no documented way |
|
|
133 | to have optional dependencies with CPAN. doh :( |
|
|
134 | - avoid running some tests on windows because they would fail due to |
|
|
135 | perl bug (broken fork, broken pipes...). |
|
|
136 | - work around perl on windows bugs where perl returns undocumented |
|
|
137 | error codes for sysread, syswrite etc. by taking advantage |
|
|
138 | of AnyEvent's workaround for that problem. |
|
|
139 | - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around |
|
|
140 | a common perl implementation bug on windows. |
|
|
141 | - use unix domain sockets in testsuite to work around |
|
|
142 | common perl implementation bugs on widows (they are emulated by |
|
|
143 | tcp sockets on windows. ugh.) |
|
|
144 | |
|
|
145 | 4.71 Sat May 24 20:01:27 CEST 2008 |
|
|
146 | - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()"). |
|
|
147 | - take advantage of async name resolution of AnyEvent::Util. |
|
|
148 | - work around brutal inet_aton override in Coro::LWP. |
|
|
149 | - take advantage of the readyhook in Coro::EV, for smoother |
|
|
150 | scheduling. |
|
|
151 | |
|
|
152 | 4.7 Sun May 11 00:32:19 CEST 2008 |
|
|
153 | - completely reworked the Coro manpage. |
|
|
154 | - added Coro::AnyEvent, generic event loop integration. |
|
|
155 | - implement cancel, ready and kill commands in Coro::Debug. |
|
|
156 | - document find_coro in Coro::Debug. |
|
|
157 | - incompatible change: rename has_stack to has_cctx. |
|
|
158 | - Coro::AIO and Coro::BDB no longer force event model detection, |
|
|
159 | use AnyEvent::AIO and AnyEvent::BDB. |
|
|
160 | |
|
|
161 | 4.6 Sat Apr 26 10:05:14 CEST 2008 |
|
|
162 | - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported |
|
|
163 | by the Coro module. It was a mistake to have it in the first place. |
|
|
164 | - (experimental) support for activestate perl 5.10 (method "w"). |
|
|
165 | - (experimental) support for strawberry perl (method "a"). |
|
|
166 | - coro_sigelem_set did not return a value although it had to, |
|
|
167 | actual impact unknown. |
|
|
168 | |
|
|
169 | 4.51 Mon Apr 14 13:28:27 CEST 2008 |
|
|
170 | - make it compile again on 5.8. |
|
|
171 | |
|
|
172 | 4.50 Thu Apr 10 09:43:17 CEST 2008 |
|
|
173 | - I did it twice! (see 4.49). |
|
|
174 | |
|
|
175 | 4.49 Sun Apr 6 21:23:31 CEST 2008 |
|
|
176 | - grr, instead of compiling the recent changes on 5.10 only they |
|
|
177 | were compiled on 5.8 only. |
|
|
178 | |
|
|
179 | 4.48 Sun Apr 6 20:36:46 CEST 2008 |
| 8 | - allow coroutine switches during eval's under 5.10.x, as it seems |
