 Revision history for Perl extension Coro.
 
+TODO: better (earlier) error messages on broken transfer's
+
+3.
+        - INCOMPATIBLE CHANGE: $/ is now per-coroutine.
+        - incompatible change: transfer flags are now per-state.
+	- give a better error message on deadlock.
+        - document Coro::nready.
+        - enhanced testsuite.
+
+3.01 Sun Dec  3 23:47:42 CET 2006
+	- forgot to include Coro::Timer.
+
+3.0  Sun Dec  3 22:57:25 CET 2006
+	- the "FINALLY COMPLETELY STABLE" release (coming soon:
+          the "FAMOUS LAST WORDS" release).
+	- implement a new stack sharing algorithm, which uses a stack
+          pool (size currently hardcoded).
+        - make stack sharing mandatory (it no longer uses a heuristic).
+        - eval/die no longer cause weird problems under heavy use.
+        - Coro::Event could cause livelocks if it was used but
+          no Coro::Event watchers were used.
+        - Coro::Event now uses asynccheck as prepare does not
+          check for changed watchers.
+        - Coro::Event allows multiple waiting coros and will wake up one
+          per event.
+        - Coro::Event should be cleaner and more efficient now.
+        - new utility function Coro::unblock_sub.
+        - document the sad fact that Event is no longer reentrant.
+        - putting a coroutine into the ready queue twice could under
+          some circumstances lead to stack corruption.
+        - minor incompatibility: subclassing Coro::State is supported
+          directly now without going through a _coro_state member.
+        - state/coro switching is much faster now.
+        - very minor optimisations and code/documentation cleanup.
+        - avoid problems due to compiler inlining.
+        - removed timers from Coro::Timer -> use AnyEvent instead.
+        - replaced Coro::idle coroutine by (cleaner) idle handler.
+        - updated to newest libcoro.
+        - implement enhanced support for valgrind.
+        - implement is_ready and return value for ready.
+        - removed Coro::Cont, it was a misnomer (it's generators),
+          and it was somewhat annoying to get it right. Will come back
+          if somebody asks for it :)
+        - many ->wait methods and Coro::Event could return
+          spuriously without the event having happened.
+
+2.5  Tue Nov  7 12:22:33 CET 2006
+        - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
+          use AnyEvent, moved them to Coro/.
+	- added Coro::LWP which contains all the uglyness required to
+          make LWP non-blocking.
+	- should work with perl 5.9.x now (Andreas König made me do it).
+        - fixed another bug in Coro::Select when the timeout was undef.
+        - reuse PL_start_env for all coros, saves some memory per coroutine.
+        - manage PL_top_env differently, hopefully to avoid panic: top_env.
+        - timeout argument was not properly used in Coro::Socket.
+        - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
+        - emulate undocumented(!) functionality of IO::Socket required
+          by LWP(!!).
+        - updated eg/lwp to work with newer lwp's.
+        - remove "FATAL: uncaught exception" prefix. Coroutines that die
+          kill the whole process, just as exceptions in the main "coroutine"
+          did already.
+
+2.1  Wed Nov  1 23:01:13 CET 2006
+        - fix a long-standing bug in Coro::Select where select with
+          zero timeout would instead change the current default filehandle.
+	- use a simpler and hopefully more robust way to clone padlists
+          (uses less memory and a perl function instead of our own).
+        - coro can now create a stack guard area on many architectures.
+        - Coro::AIO properly reexports additional functions from IO::AIO.
+	- updated libcoro with a workaround for OS X,
+          pach and testing by Michael Schwern.
+
+2.0  Tue Oct 24 05:47:17 CEST 2006
+	- support additional aio requests in Coro::AIO.
+
+1.9  (never properly released due to a glitch)
+
+1.8  Thu Feb  2 00:59:06 CET 2006
+	- applied suggested patch by SAMV to avoid problems during stupid
+          mark & sweep gc run.
+        - applied patch by Scott Walters for 5.9.3 compatibility.
+
+1.7  Tue Dec 27 01:41:58 CET 2005
+	- added Coro::AIO, a thin wrapper around IO::AIO.
+	- improved Makefile.PL explanations.
+
+1.6  Mon Dec 12 21:30:05 CET 2005
+	- additionally save PM_curpm might fix as-of-yet
+          unseen problems with regex matches being attributed to the
+          wrong package.
+        - add t/10_bugs.t, which currently checks against imho broken
+          perls that use 0.26MB of stack space per Perl_magic_get
+          invocation (newer linuxes) as opposed to the 0.0002MB perl
+          normally uses.
+        - make stacksize configurable for the ultimate debian experience.
+
+1.51 Mon Dec 12 18:48:36 CET 2005
+	- remove debugging warn() accidentally left in Coro::Select.
+
+1.5  Tue Nov 29 13:32:44 CET 2005
+	- use Coro::Event inside Coro::Select to avoid spurious deadlocks.
+        - fix Coro::Select 'select'.
+        - strict'ify some modules.
+	- libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
+        - use XSLoader in selected modules.
+        - remove some 5.6 compatibility cruft.
+
 1.4  Tue Sep  6 00:11:05 CEST 2005
 	- libcoro did not take into account the trampoline on amd64,
           when 'l'inux method was used.
