shivers 6d8929b608 defrec.scm -- trivial doc bug in comments. 
jcontrol1.c -- signal handler stuff

signal handler hacking -- added Unix signals to VM's interrupt set.

shivers bcdc349bcf New, improved machinery for handling optional args. 1996-04-19 18:55:31 +00:00
shivers ea45fca8ef Hacked the system to use the new LET-OPT optional argument machinery, 
LET-OPTIONAL, LET-OPTIONAL*, and :OPTIONAL. The new macros are
faster and easier to read than the old PARSE-OPTIONALS and OPTIONAL-ARG
procedures.

shivers 6b42e9d7aa 1. Hacked fork so that if it fails and the zombie autoreap policy is 'early, 
we do a zombie-reap and then retry the fork. This way, if the fork fails
because the process table filled up, you can clean up and win.

It's not the right answer, but the right answer depends on handling SIGCHLD
interrupts, so we can't implement it now.

2. Hacked the optional arg handling to use the new LET-OPT machinery.

shivers 1a0d6a2af4 Fixed delimited readers -- there was confusion about what the handle-delimiter 
arg was. It now defaults uniformly to 'trim.

shivers 2c9e06d6ae Changed char to int so non-ASCII chars wouldn't be sign-extended -- was 
blowing char-set test in skip_chars.

applied to a non-ASCII char. Now fixed.

shivers 00af71f77d There was a weird bug in the GC system. The image-writing code causes a 
GC to assemble a compacted heap image in newspace which it then writes out
to disk. Then the VM calls ABORT-GC to cancel the GC operation, which scans
the current space, fixing up the "broken hearts" -- restoring word 1 of
each structure that got clobbered with a forwarding pointer.

Unfortunately, someone (possibly myself) had inserted a post_gc_fdports() call
into the VM between the gc and the abort. This procedure updates a C vector of
Scheme values (fdports[]) by following forwarding pointers -- BUT -- in this
instance we didn't really want to break hearts, and the abort-gc code didn't
know about the fdports[] vector, so it couldn't undo the effects. This caused
the fdports[] vec to point into hyperspace after the image dump, and *that*
meant on the next GC, all the live ports were considered dead. Oops.

The fix was to remove this bogus call. The post_gc_fdports() proc is now
called only after a *real* GC.
