Also implement + a new method "sem" to get at the underlying semaphore object. + - implement Coro::Channel in terms of Coro::Semaphore, for a moderate + (in comparison) 20-40% speedup. + - used new SLF interface to reimplement Coro::Signal gaining + some unknown (because I was too lazy), but certain, speedup, and also + making signals reliable for the first time. + - used new SLF interface and other optimisations to speed up async_pool + by a factor of two. It also doesn't rely on perl's exception mechanism + to exit anymore. The overhead for terminating an async_pool, coro over + a normal async is now very small. + - sped up coroutine creation/destruction by 40%. + - forgot to include Coro/libcoro/README in the dist for all these years. + - work around a freebsd pthreads bug (manual testcancel is required as + pthread_cond_wait isn't a cancellation point on freebsd). + - use new rouse functions to speed up and simplify Coro::BDB. + - make "prefer perl native functions" work with threaded perls. + - condense Coro::Debug ps output, hint at v and w flags. + - (libcoro) lots of minor cleanups and portability improvements. + +4.914 Wed Nov 19 12:54:18 CET 2008 + - fix a disastrous bug in the readline optimisation + introduced in 4.801. + +4.913 Sat Nov 15 07:58:28 CET 2008 + - async_pool did free a scalar value twice + ("Attempt to unreference..."). + +4.912 Thu Nov 13 18:31:23 CET 2008 + - minor cleanups. + - use much larger stacks on linux and perl < 5.8.8. + - Coro::Debug::new_unix_server did not unlink the socket + when destroyed. + +4.911 Tue Nov 11 04:26:17 CET 2008 + - "port" to threaded perls. + +4.91 Mon Nov 10 05:36:38 CET 2008 + - the ->throw exception object no longer leaks. + - creating a new cctx leaked a scopestack entry (memleak). + - new coroutines didn't get created with a zero flags field + (unknown impact). + - calling ->throw on a not-yet-started coroutine should now work + instead of being ignored. + - ->throw is now supported on Coro::State objects. + - clean up cctx creation code a bit. + - entersub is actually a UNOP, not a LOGOP (not a bugfix). + +4.9 Sat Nov 8 17:45:27 CET 2008 + - (libcoro) did not preserve rbp with CORO_ASM (we are getting there). + - (libcoro) no longer leak threads in the experimental pthread backend, + also speed it up considerably. + - (libcoro) do not rely on makecontext passing void *'s unscathed. + - fix compiletime dependencies on libcoro in the Makefile. + - cctx_count wasn't always updated properly. + - Coro::State::cctx_stacksize wasn't applied correctly. + - new function Coro::State::cctx_max_idle. + - the default max number of idle C contexts is now 4. + - (libcoro) try harder to get _setjmp/_longjmp. + - (libcoro) cleanup and extend the libcoro API to officially + allow the creation of empty source contexts. + - very experimental workaround for the totally broken netbsd platform. + - tried to hack around openbsd bugs. + +4.804 Wed Nov 5 16:36:00 CET 2008 + - Coro::Debug::new_unix_server would not create a non-blocking listening + socket, sometimes causing freezes. + - (libcoro) fix misaligned stack points for setjmp and assembly + methods, which can cause crashes on x86/x86_64 with a sufficiently + aggressive compiler. + - new function: Coro::Debug::new_tcp_server. + - move ->throw into the Coro class because it only works on coro objects. + +4.803 Mon Nov 3 17:16:12 CET 2008 + - (libcoro) use a global asm statement to become independent of gcc + otpimisations for CORO_ASM (thanks to pippijn for the idea). + - try to workaround yet another broken bsd, this time dragonfly. + 4.802 Thu Oct 30 10:56:12 CET 2008 - support -fno-omit-frame-pointer on x86 with the assembly method. - tune 01_unblock.t tests a bit.
