mainzelm d30130ab03 Deadlock-free resource locking. 2002-08-13 06:49:22 +00:00
mainzelm 021cd1efc1 + Let WITH-HANDLER take care of the resource lock.
+ Removed some duplicate alignments of process resources and moved
other closer the the actual system call

mainzelm 0b35dbbe2f exec-path-list is a thread-fluid now. 2002-05-07 08:58:53 +00:00
sperber 37948e173d Preserve ports in forked child.
The use of NARROW had borked this.

sperber 1d35626709 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.

mainzelm 43cd435bad Fixed cut and paste error in with-umask-aligned. 2002-04-29 11:25:17 +00:00
mainzelm 4a7620c882 Fixed bug in setenv: #f was not handled as deleting the variable.
Also removed superfluous list-copying before call to alist-update as
this has no side effects.

mainzelm 8cb11125ae + Fixed small bug in fork: command level wasn't resumed in the no-thunk case.
+ Optional continue-threads argument for fork/pipe and fork/pipe+

sperber 3717053d60 Preserve thread fluids when forking. 2002-04-12 14:29:38 +00:00
sperber 349fff06c1 Basic FORK and and %FORK now start a new command level inside the
child process, thus preventing other threads from continuing to run.

Both take an additional optional argument that, when true, reverts the
old behavior of continuing all threads.

Moreover, use WITH-CONTINUATION NULL-CONTINUATION in CALL-TERMINALLY
to get us more space.

mainzelm 5500490a1d Sleazy fix for the inliner: procedures can't "return" error, so wrap a
