9 | TODO: guard as SLF - to avoid deadlocks. |
|
|
10 | - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). |
|
|
11 | |
|
|
12 | 5.0 |
|
|
13 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |
|
|
14 | stability issues. |
|
|
15 | - bump API version to 7 - all dependents must be recompiled. |
|
|
16 | - removed timed_* functions - they were not being used anyways |
|
|
17 | and should be replaced by a more generic mechanism - |
|
|
18 | and were annoying to support anyways :) |
|
|
19 | - removed SemaphoreSet's waiter method - use sem instead. |
|
|
20 | - Coro::Semaphore->adjust didn't correctly wake up enough waiters. |
|
|
21 | - async_pool did free a scalar value twice |
|
|
22 | ("Attempt to unreference..."). |
|
|
23 | - fix a longstanding bug where calling terminate on a coro that |
|
|
24 | was waiting for a semaphore that was just becoming available |
|
|
25 | would cause a deadlock (semaphore would get into a state where |
|
|
26 | it was available but waiters were still blocked). |
|
|
27 | - calling throw on a coroutine that is waiting for a semaphore will |
|
|
28 | no longer make it acquire the semaphore (and thus leak a count). |
|
|
29 | - perl's process emulation is now not even theoretically supported |
|
|
30 | anymore. |
|
|
31 | - new functions Coro::rouse_cb and Coro::rouse_wait. |
|
|
32 | - new function Coro::Semaphore::wait. |
|
|
33 | - use named constants in Coro::Channel (Richard Hundt). |
|
|
34 | - directly patch the entersub opcode calling SLF functions (cede, |
|
|
35 | transfer and so on). this does speed up context switching, but |
|
|
36 | more importanly, it frees us from the hardcoded behaviour of |
|
|
37 | entersub, so we might actually be able to return something from |
|
|
38 | those functions and atcually create new ones. |
|
|
39 | - take advantage of __builtin_frame_address on gcc. |
|
|
40 | - expose THX in coroapi (not sure whether this was a wise decision, |
|
|
41 | as "threaded" perls are running at half speed anyways). |
|
|
42 | - implement execute_slf (schedule-like-function) interface that makes |
|
|
43 | it possible to implement schedule-like-functions in XS. |
|
|
44 | - use new SLF interface to massively speed up Coro::EV by roughly a |
|
|
45 | factor of two. |
|
|
46 | - used new SLF interface to massively speed up Coro::Semaphore by a |
|
|
47 | factor of three. |
|
|
48 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
49 | four and reduce its memory usage considerably. |
|
|
50 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
51 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
52 | a new method "sem" to get at the underlying semaphore object. |
|
|
53 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
54 | (in comparison) 20-40% speedup. |
|
|
55 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
56 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
57 | making signals reliable for the first time. |
|
|
58 | - forgot to include Coro/libcoro/README in the dist for all these years. |
|
|
59 | - work around a freebsd pthreads bug (manual testcancel is required as |
|
|
60 | pthread_cond_wait isn't a cancellation point on freebsd). |
|
|
61 | - use new rouse functions to speed up and simplify Coro::BDB. |
|
|
62 | - make "prefer perl native functions" work with threaded perls. |
|
|
63 | - (libcoro) lots of minor cleanups and portability improvements. |
|
|
64 | |
|
|
65 | 4.913 Sat Nov 15 07:58:28 CET 2008 |
|
|
66 | - async_pool did free a scalar value twice |
|
|
67 | ("Attempt to unreference..."). |
|
|
68 | |
|
|
69 | 4.912 Thu Nov 13 18:31:23 CET 2008 |
|
|
70 | - minor cleanups. |
|
|
71 | - use much larger stacks on linux and perl < 5.8.8. |
|
|
72 | - Coro::Debug::new_unix_server did not unlink the socket |
|
|
73 | when destroyed. |
|
|
74 | |
|
|
75 | 4.911 Tue Nov 11 04:26:17 CET 2008 |
|
|
76 | - "port" to threaded perls. |
|
|
77 | |
|
|
78 | 4.91 Mon Nov 10 05:36:38 CET 2008 |
|
|
79 | - the ->throw exception object no longer leaks. |
|
|
80 | - creating a new cctx leaked a scopestack entry (memleak). |
|
|
81 | - new coroutines didn't get created with a zero flags field |
|
|
82 | (unknown impact). |
|
|
83 | - calling ->throw on a not-yet-started coroutine should now work |
|
|
84 | instead of being ignored. |
|
|
85 | - ->throw is now supported on Coro::State objects. |
|
|
86 | - clean up cctx creation code a bit. |
|
|
87 | - entersub is actually a UNOP, not a LOGOP (not a bugfix). |
|
|
88 | |
|
|
89 | 4.9 Sat Nov 8 17:45:27 CET 2008 |
|
|
90 | - (libcoro) did not preserve rbp with CORO_ASM (we are getting there). |
|
|
91 | - (libcoro) no longer leak threads in the experimental pthread backend, |
|
|
92 | also speed it up considerably. |
|
|
93 | - (libcoro) do not rely on makecontext passing void *'s unscathed. |
|
|
94 | - fix compiletime dependencies on libcoro in the Makefile. |
|
|
95 | - cctx_count wasn't always updated properly. |
|
|
96 | - Coro::State::cctx_stacksize wasn't applied correctly. |
|
|
97 | - new function Coro::State::cctx_max_idle. |
|
|
98 | - the default max number of idle C contexts is now 4. |
|
|
99 | - (libcoro) try harder to get _setjmp/_longjmp. |
|
|
100 | - (libcoro) cleanup and extend the libcoro API to officially |
|
|
101 | allow the creation of empty source contexts. |
|
|
102 | - very experimental workaround for the totally broken netbsd platform. |
|
|
103 | - tried to hack around openbsd bugs. |
|
|
104 | |
|
|
105 | 4.804 Wed Nov 5 16:36:00 CET 2008 |
|
|
106 | - Coro::Debug::new_unix_server would not create a non-blocking listening |
|
|
107 | socket, sometimes causing freezes. |
|
|
108 | - (libcoro) fix misaligned stack points for setjmp and assembly |
|
|
109 | methods, which can cause crashes on x86/x86_64 with a sufficiently |
|
|
110 | aggressive compiler. |
|
|
111 | - new function: Coro::Debug::new_tcp_server. |
|
|
112 | - move ->throw into the Coro class because it only works on coro objects. |
|
|
113 | |
|
|
114 | 4.803 Mon Nov 3 17:16:12 CET 2008 |
|
|
115 | - (libcoro) use a global asm statement to become independent of gcc |
|
|
116 | otpimisations for CORO_ASM (thanks to pippijn for the idea). |
|
|
117 | - try to workaround yet another broken bsd, this time dragonfly. |
|
|
118 | |
|
|
119 | 4.802 Thu Oct 30 10:56:12 CET 2008 |
|
|
120 | - support -fno-omit-frame-pointer on x86 with the assembly method. |
|
|
121 | - tune 01_unblock.t tests a bit. |
|
|
122 | |
|
|
123 | 4.801 Wed Oct 22 18:33:37 CEST 2008 |
|
|
124 | - improve readline speed for very long "lines". |
|
|
125 | - backport to 5.8.8. |
|
|
126 | |
|
|
127 | 4.8 Thu Oct 2 13:34:40 CEST 2008 |
|
|
128 | - new function Coro::AIO::aio_wait. |
|
|
129 | - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent". |
|
|
130 | - greatly speed up and reduce memory usage of Coro::AIO requests. |
|
|
131 | - implement some other ยต-optimisations. |
|
|
132 | |
|
|
133 | 4.749 Mon Sep 29 14:40:12 CEST 2008 |
|
|
134 | - port to slow and broken pseudo-threaded perls. (courtesy pippijn). |
|
|
135 | |
|
|
136 | 4.748 Sat Sep 27 14:03:19 CEST 2008 |
|
|
137 | - implement, but do not document, PerlIO::cede(granularity). |
|
|
138 | - Coro::Storable forgot to wrap Storable::pstore. |
|
|
139 | - work around the multitude of leaks and memory corruption |
|
|
140 | bugs in PerlIO::via by using our own C-level perliol. As a side |
|
|
141 | effect, Coro::Storable is now much, much, much faster. |
|
|
142 | |
|
|
143 | 4.747 Tue Sep 23 01:59:41 CEST 2008 |
|
|
144 | - fix a per-cv memleak (one empty array was leaked per |
|
|
145 | code reference). |
|
|
146 | - avoid a crash in coro->call|rss when the coroutine was already |
|
|
147 | destroyed (most noticably when using Coro::Debug::ps :) |
|
|
148 | - also protect *Storable::FILE. |
|
|
149 | - push up default storable granularity to 20ms. |
|
|
150 | |
|
|
151 | 4.746 Sun Sep 21 03:22:20 CEST 2008 |
|
|
152 | - be more insistent on locking Storable against reentrancy |
|
|
153 | in Coro::Storable. |
|
|
154 | - move swap_def?v and throw to Coro::State, as documented. |
|
|
155 | |
|
|
156 | 4.745 Thu Jul 24 00:14:38 CEST 2008 |
|
|
157 | - remove debugging code related to MgPV_nolen_const, also try to |
|
|
158 | make it compile with perl 5.8.6 (yes, apple apparently loves |
|
|
159 | outdated software). Reported by John S. |
|
|
160 | |
|
|
161 | 4.744 Tue Jul 8 22:06:35 CEST 2008 |
|
|
162 | - correctly provide default DIE/WARN handlers as documented. |
|
|
163 | - also overwrite PL_vtbl_sigelem.svt_clear, even though current |
|
|
164 | implementations inside perl work fine for us. |
|
|
165 | |
|
|
166 | 4.743 Mon Jun 16 00:21:57 CEST 2008 |
|
|
167 | - when using Coro::EV without running EV::loop it could |
|
|
168 | result in busy-waiting for events, this has been fixed. |
|
|
169 | - reduce codesize and improve performance by using EV_DEFAULT_UC. |
|
|
170 | |
|
|
171 | 4.742 Sat May 31 14:10:21 CEST 2008 |
|
|
172 | - implement a workaround for (some) perl <5.8.8 versions. |
|
|
173 | - require EV 3.3+. |
|
|
174 | |
|
|
175 | 4.741 Fri May 30 23:33:09 CEST 2008 |
|
|
176 | - tell netbsd how utterly broken their imitation of an OS is |
|
|
177 | and refuse to build by default if pthreads are in use. |
|
|
178 | - switch to "s" method on all bsd's by default, as their ucontext |
|
|
179 | stuff seems just too broken. |
|
|
180 | - fix a bug in Coro::Select. |
|
|
181 | |
|
|
182 | 4.74 Thu May 29 20:05:31 CEST 2008 |
|
|
183 | - do not test Coro::LWP for lack of dependencies. |
|
|
184 | - do not test Coro::Select for lack of working perls. |
|
|
185 | |
|
|
186 | 4.73 Thu May 29 2008 |
|
|
187 | - fix a bug in Coro::EV which would cause it to block despite |
|
|
188 | there being runnable coroutines. |
| 8 | - sprinkle "no warnings" freely over everything, also suppress |
