Redo the forking-without-the-threads fix in a way not involving
...
command levels (as there *are* no command levels for things like scsh
-c):
There's now a new asynchronous event, similar to SPAWN, called NARROW.
It spawns off a new scheduler with just one thread (which runs the
thunk provided as an argument to NARROW) and blocks the current one
until the narrowed scheduler finishes.
For this to work, two schedulers need to be in place: the root
scheduler which performs the housekeeping, and another one inside that
which is the one the program uses---otherwise it's the root scheduler
that's blocked, and that means no housekeeping gets done. This is
trivially the case for interactive mode, as the command-levels all
have their own schedulers, but we also need to make sure scsh's entry
point fires up its own initial scheduler.

Provide names for housekeeping threads for better debugging.

New module language from S48 0.57.

Be even more thorough about releasing port locks after exceptions.

Remove STEAL-CHANNEL-PORT! which has been unused for a while now and
...
uncomfortably shared code with STEAL-PORT!

Make sure port locks get released after I/O errors.
2002-02-26 14:40:21 +00:00

Added hook to align cwd and umask for the S48 system.

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.

Let thread-uid->thread invoke the GC if it encounters multiple threads with the same uid.

A thread may life in multiple queues.

Change from Richard, Scheme 48 0.56 -> 0.56.9:
...
Define exception handler for TIME opcode.

Really fixed the bug in sleep. The previous fix was totally broken.
2001-06-07 16:14:29 +00:00
fd264012b9
Added argument conversion for sleep (prevents a core dump on inexact numbers).

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
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

Hand out the port and not just port-data to the handler.

Adapted some of Richard's changes for char-ready? and output-port-ready?.
2001-03-23 10:59:07 +00:00
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|#

it. Removed machinery in low-interrupt.
