name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
where possible.
* symbols.c (scm_sysintern0): Fixed the function name in a
scm_misc_error invocation.
* print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
use scm_return_first to ward off latent GC bug that Mikael caught.
* async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
used before but should've been.
SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
in terms of SCM_SLOPPY_NCONSP instead of repeating the
expression.
* symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
define latter in terms of sloppy variant.
* strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
define latter in terms of sloppy variant.
* scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
out the commonality of the various basic SCM_VALIDATE_foop
macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
coercion to an integer which is more advanced than desired and
SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
appropriately for the various _MIN, _MAX, _RANGE macros. Drop
some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
part of its SCM_CONSP test).
* socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
* scm_validate.h: Added SCM_VALIDATE_THREAD.
* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
that SCM_FOOP macros all now include SCM_NIMP in their expansion.
This simplifies lots of code, making it far more readable.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
marking code, and make marker routines only responsible for
turning up outgoing pointers.
* gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
before calling the marking function. Don't call the marking
function if it's zero.
* markers.c (scm_mark0): Just return #f. This function isn't
necessary at all now, but it's harmless to call it. We'll leave
it in so other folks' code doesn't croak at link time.
(scm_markcdr): Don't call SCM_SETGC8MARK.
* async.c (mark_async): Don't call SCM_SETGC8MARK.
* dynl.c (mark_dynl_obj): Same.
* root.c (mark_root): Same.
* srcprop.c (marksrcprops): Same.
* unif.c (markra): Same.
* variable.c (scm_markvar): Same.
* ports.c (scm_markstream): Same.
(void_port_ptob): Specify zero for our marking function.
* debug.c (debugobjsmob): Same.
* dynwind.c (guardsmob): Same.
* filesys.c (dir_smob): Same.
* fluids.c (fluid_smob): Same.
* fports.c (scm_fptob, scm_pipob): Same.
* mallocs.c (mallocsmob): Same.
* regex-posix.c (regex_t_smob): Same.
* smob.c (freecell, flob, bigob): Same.
* threads.c (thread_smob, mutex_smob, condvar_smob): Same.
* throw.c (jbsmob, lazy_catch_funs): Same.
* _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
loop.
* posix.c (scm_uname): interpret only negative values as an error.
Solaris normally returns a positive value.
* script.c (scm_compile_shell_switches): if we are not going into
an interactive repl, set scm_mask_ints to zero so that asyncs can
run.
* simpos.c (scm_system): don't ignore/unignore signals around
the "system" call.
* posix.c (scm_open_pipe): don't ignore/unignore signals around
the "popen" call.
* init.c (scm_boot_guile_1): don't call scm_init_signals, it's
done in boot-9.scm instead.
* scmsigs.c, async.c: Major rewriting of signal handling code.
(scm_sigaction): new procedure.
(scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
timing.
(scm_raise): return unspecified, throw error on failure.
* boot-9.scm: signal-handler, alarm-thunk: removed.
don't define ticks-interrupt etc.
top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
during call to scm-style-repl.
* acconfig.h: mention HAVE_RESTARTS.
* configure.in: check for sigaction and restartable system calls.
sure how this was supposed to work.
(scm_async_click): don't send SCM_TICK_SIGNAL.
(scm_init_async): don't initialize %tick-thunk.
* the following change doesn't affect the Scheme interface:
gc-thunk is called at the end of garbage collection. however it's
no longer implemented by pretending it's a signal.
* gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
system async corresponding to scm_gc_thunk.
* async.h: declare scm_gc_async.
* async.c (scm_sys_gc_async_thunk): apply the thunk named by
gc-thunk directly, instead of going through a signal handler.
(scm_gc_async): new variable, points to the GC system-async.
(scm_init_async): save the GC async as scm_gc_async instead
of using system_signal_asyncs.
(scm_gc_vcell): new variable, stores the gc-thunk vcell.
