sperber baf1dbbf76 Pass optional arguments from FORK-THREAD to SPAWN. 2002-02-04 11:34:17 +00:00
mainzelm 2b1d8a3d01 Let s48-do-gc return 0 so the PreScheme compiler will emit the correct
signature of the function.
2002-02-01 10:25:50 +00:00
sperber 7c026ff0b4 Fix external-call-from-callback problem leading to spurious
gc-protection-mismatch exceptions.
2002-01-27 20:20:53 +00:00
mainzelm 284d89fe12 Added hook to align cwd and umask for the S48 system. 2001-12-19 09:14:15 +00:00
mainzelm 8bba3a13e1 Adjust top of stack as well. 2001-12-04 13:06:12 +00:00
sperber 136e313af7 New implementation of (no-inheritance) thread-local cells and thread
fluids.

New implementation of syslog.

Both are to be compatible with what's actually probably going into
Scheme 48.
2001-12-03 15:21:46 +00:00
sperber b5180b35af Make naming consistent with current Scheme 48:
argtype -> argument_type
argnumber -> argument_number
2001-12-03 15:19:48 +00:00
mainzelm 1ed75d8531 Let thread-uid->thread invoke the GC if it encounters multiple threads with the same uid. 2001-11-08 10:24:41 +00:00
mainzelm 405512e0db Expported the rest of the port-handler accessors. 2001-10-25 07:24:42 +00:00
mainzelm fe6a9db1e5 Renamed scsh-events to sigevents. 2001-10-18 09:02:52 +00:00
mainzelm 59bd2ab6e4 Peek on char-source-input-ports does not work. Added error message to report this. 2001-10-05 16:25:41 +00:00
mainzelm 9552e7900a A thread may life in multiple queues. 2001-10-04 11:16:15 +00:00
mainzelm 2e3dd4b65c Fixed small typo. 2001-09-12 13:42:29 +00:00
sperber 7a45d9cc01 Change from Richard, Scheme 48 0.56 -> 0.56.9:
Define exception handler for TIME opcode.
2001-07-10 13:13:27 +00:00
mainzelm 569dbe6649 Bug fix by Richard for finite types used within macros. 2001-07-09 14:15:51 +00:00
mainzelm 68eb897e20 Merged in macro expander changes from Scheme 48 0.56. 2001-07-09 14:15:05 +00:00
mainzelm 8b44999d55 Really fixed the bug in sleep. The previous fix was totally broken. 2001-06-07 16:14:29 +00:00
mainzelm fd264012b9 Added argument conversion for sleep (prevents a core dump on inexact numbers). 2001-05-30 15:55:55 +00:00
sperber 8f02923726 Added thread-fluids which are a cross between thread cells and fluids.
They encapsulate thread-local state and have a binding construct
analogous to LET-FLUID.
2001-05-28 13:44:48 +00:00
sperber 1e212d78a4 Bug fix:
I had forgotten to mark the thread-cell value environment as read-only
when it's passed on to a spawned thread.  Do that now.
2001-05-28 13:31:01 +00:00
sperber 21a8e255eb Added thread-cells structure for thread-local cells.
These can be used (together with fluids) to implement something akin
to PLT's and Chez's parameters for holding thread-local state such as
CWD, syslog channel, etc.
2001-05-22 14:58:15 +00:00
mainzelm 384c28fab4 Hand out the port and not just port-data to the handler. 2001-04-09 07:55:50 +00:00
mainzelm 5d4b66daf4 Upgraded inliner from 0.54. There is still a bug as a call to error must not be the last expression of a procedure. No fix for now, use (if #t (error ...)) as a workaround 2001-03-25 12:08:45 +00:00
mainzelm 0b00ab0380 Upgraded inliner from 0.54. There is still a bug as a call to error must not be the last expression of a procedure. No fix for now, use (if #t (error ...)) as a workaround 2001-03-25 11:21:58 +00:00
mainzelm 25f395c1d0 * New package definitions now that we have SRFI-13 and 14
* Introduced the nomenclature "sigevent"
2001-03-23 12:45:31 +00:00
mainzelm 9b4bb8a19d Adapted some of Richard's changes for char-ready? and output-port-ready?. 2001-03-23 10:59:07 +00:00
mainzelm 9035313159 Added nested multi-line comments. The implementation has two
drawbacks:
1.) Since # and | may be part of an identifier, a#|bla|# is
read as a#|bla|# not as a.

2.) The REPL won't read a comment for its own, it will wait for
another value:
>#|bla|#
