2969637c9e * popen.scm (close-process-quietly): new procedure. use it from 
reap-pipes to avoid errors or hanging during background cleanup.

451e591cdd Some SCM/scm_bits_t type strictness fixes. 2000-04-07 10:41:39 +00:00
Michael Livshin
e94e3f21d6 * async.[ch]: unexpose low-level async access macros (thanks to 
Dirk Herrmann).

* validate.h: move async validation macros to async.c (nobody else
needs them anyway), and rename them.

843e4e9d17 * async.h: kill the scm_async_t struct. having a heap cell 
pretending to be a C struct is not helthy, and is not needed here
anyway, as asyncs happily fit in one heap cell.

* async.c: reflect the fact that asyncs are now represented by
single heap cell each.

1de052a72c * error.c (scm_syserror): save errno before doing anything else, 
since it's used in two expressions and may get mutated (thanks to
	Dirk Herrmann).

186cf94654 * format.scm (format:obj->str): Handle circular references. Also, 
print improper lists with (x y . z) syntax rather than as
individual pairs.  (This code should probably be integrated into C
level facilities.  It is currently terribly slow.)

b87e3d4d19 * streams.scm (stream-fold, stream-for-each): don't use named let, 
because it prevents the gc from junking the stream argument.
 2000-04-03 15:38:35 +00:00
Michael Livshin
50fecba92d * guardians.c (scm_guardian_zombify): mark all zombies in a 
separate loop after processing all the currently known live
guardians, so as to not introduce order dependencies (thanks to
Gary Houston).  also, make another outer loop to process zombified
guardians (which are uncovered while marking zombies).

e46f3fa6ba * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the 
empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
	use of an improper list (which breaks g_print.  g_print isn't
	used).
	guardians.c: Added more comments and modified the make-guardian
	docstring.  Reordered a few procedures.

8cc58ec1cc * tests/ports.test (non-blocking-I/O): a couple more details: 
a) combine the O_NONBLOCK flag with the default flags instead
	of replacing them.  b) check EWOULDBLOCK as well as EAGAIN.

5c90be5282 * coop-defs.h (struct coop_t): Added `sto'-field again because of 
binary compatibility---let's remove it next time we alter some
major structure.

6219b5eb41 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create, 
coop_mother, coop_child): New variables.
(mother): New function.
(coop_create): New thread spawning mechanism which uses a "mother
thread".  The "dummy" pthreads aren't healthy enough to give birth
to new threads since Linux threads thinks they are asleep.
 2000-03-30 23:23:10 +00:00

2f511ab1aa * coop-defs.h (struct coop_t): Removed dummy_mutex.

Mikael Djurfeldt
31bc6de36a * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type 
for scm_tc16_thread.  As the current COOP threads are written, GC
is not supposed to manage storage for threads.
 2000-03-29 01:58:17 +00:00
Mikael Djurfeldt
ef18914a94 * error.c (scm_error): Don't try to throw an error if 
scm_gc_heap_lock is true.
 2000-03-29 01:57:54 +00:00
Mikael Djurfeldt
f85a9bcf5f * coop.c (coop_finish): New function. Called at exit. 
(coop_aborthelp): Free thread structures when threads die.
Finished LinuxThreads compatibility support => COOP threads now
mesh with LinuxThreads.

Mikael Djurfeldt
0e551780ec * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread): 
Changed SETCDR --> SET_CELL_WORD_1.

* coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
when thread dies.
