* libguile/r6rs-ports.c (cbp_seek)[WHENCE == SEEK_CUR]: Break out of the
switch statement when OFFSET is zero.
Pass 'scm_wrong_type_arg_msg' a phrase suitable for use after
"expecting".
* test-suite/tests/r6rs-ports.test ("7.2.7 Input Ports")["custom binary
input port supports `port-position', not `set-port-position!'"]: New
test.
Fixes a bug introduced in cc1cd04f81
"Fix hashing of vectors to run in bounded time."
* libguile/hash.c (scm_hasher): Avoid division by zero.
* test-suite/tests/hash.test ("hash"): Add tests.
* libguile/hash.c (SCM_MIN): New macro.
(scm_hasher): In vector case, do nothing if d is 0. Make sure to
recurse with a reduced d. Move the loop out of the 'if'.
* libguile/ports.c (scm_i_port_property, scm_i_set_port_property_x):
Lock the port mutex while accessing the port alist.
* libguile/read.c (set_port_read_option): Lock the port mutex
while modifying port read options.
* libguile/gc.h:
* libguile/gc.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_gc_live_object_stats): Deprecate; it hasn't
worked in the whole 2.0 series.
* libguile/private-gc.h (SCM_DOUBLECELL_ALIGNED_P): Remove; unused.
* libguile/filesys.c (MAX, MIN): Move definitions here, from
private-gc.h.
(scm_sendfile, scm_readdir): Adapt uses of SCM_MAX and SCM_MIN to use
MAX or MIN.
* libguile/fluids.c (new_fluid): Don't run an explicit GC for the first
fluid.
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE, scm_storage_prehistory):
Enlarge from 32 kB to 512 or 1024 kB, depending on word size. Reduces
startup time by 10 or 15% by avoiding excessive
GC.
* libguile/private-gc.h: Remove SCM_DEFAULT_INIT_HEAP_SIZE_2 definition
here.
* libguile/gdb_interface.h:
* libguile/gdbint.c:
* libguile/gdbint.h: Remove. These were last modified significantly in
1997 and I think they are unused.
* libguile/guile.c: Remove use.
* libguile.h: Remove inclusion.
* libguile/Makefile.am: Remove reference.
* libguile/init.c: Remove use.
* libguile/ports.c (scm_peek_char): Don't require error cases to
set *len. Fixes a bug caught by GCC whereby an EOF while reading a
multibyte character with iconv would leave len uninitialized.
* libguile/ports.c (scm_i_port_alist, scm_i_set_port_alist_x): Removed.
(scm_i_port_property, scm_i_set_port_property_x): New procedures,
available from Scheme as '%port-property' and '%set-port-property!'.
* libguile/ports.h (scm_i_port_alist, scm_i_set_port_alist_x): Removed.
(scm_i_port_property, scm_i_set_port_property_x): New prototypes.
* libguile/read.c (set_port_read_option, init_read_options): Adapt to
use scm_i_port_property and scm_i_set_port_property_x.
* libguile/procprop.c (scm_set_procedure_property_x): Block system
asyncs while overrides_lock is held. Use dynwind block in case
an exception is thrown.
* libguile/vm-engine.c (CHECK_OVERFLOW): Call vm_expand_stack, not
vm_error_stack_overflow.
* libguile/vm.c (hard_max_stack_size, default_max_stack_size): Recast
#defines as locals. Have both hard and soft stack limits.
(initialize_default_stack_size): Set soft stack limit from
GUILE_STACK_SIZE.
(expand_stack, vm_expand_stack): Support for expanding stacks as
needed. Whee!
(make_vm): Adapt limits.
(scm_call_n): Expand stack if needed.
* libguile/vm.h (struct scm_vm): Add max_stack_size member.
* libguile/_scm.h (SCM_ASYNC_TICK_WITH_GUARD_CODE): New macro.
* libguile/vm-engine.c (VM_HANDLE_INTERRUPTS): Restore FP after
ticking.
(CACHE_FP): New macro.
(CHECK_OVERFLOW): Use CACHE_FP.
(BR_ARITHMETIC, RETURN_EXP, RETURN_ONE_VALUE, BINARY_INTEGER_OP):
(call, return-values, subr-call, foreign-call)
(resolve, define!, toplevel-box, module-box): Restore the FP from the
vp where needed.
* libguile/threads.c (thread_mark): Mark the VM stack, if we have one.
(on_thread_exit): Free the VM stack here.
* libguile/vm.c (make_vm): Allocate the VM stack using mmap, and arrange
for it to be marked by the thread marker.
(scm_i_vm_mark_stack, scm_i_vm_free_stack): New internal interfaces.
(allocate_stack, free_stack): New helpers.
