* libguile/vm-i-scheme.c (VM_VALIDATE_STRUCT): Fix the error message if
the value was not a struct.
* module/system/base/compile.scm (find-language-joint): Default to
joining at the target language.
(default-language-joiner): Allow sequences of one compiled expression
to pass through. Otherwise error as before.
(read-and-parse): New helper; actually parses.
(read-and-compile): Use read-and-parse, and fall back to
default-language-joiner.
Thanks to Nala Ginrut for the report.
* module/system/base/compile.scm (read-and-compile): Close the input
port after we read all of its data. Perhaps this cleans up some NFS
ghosts that David Pirotte was seeing.
* libguile/load.c (scm_primitive_load_path): If the second argument is a
procedure, call it like a thunk.
* doc/ref/api-evaluation.texi (Load Paths): Update docs.
* module/ice-9/boot-9.scm (resolve-interface): Use `unless'.
(try-module-autoload): Use the new primitive-load-path to detect
failure to find an appropriate file. Fixes a bug reported by Diogo
F. S. Ramos. Thanks to Noah Lavine for tracking it down.
* libguile/weak-table.c (GC_move_disappearing_link)
(move_disappearing_links): Factor out stub, as in previous weak-set
commit.
(resize_table): As in weak-set commit, finalizers do not run within
allocators.
(do_vacuum_weak_table): Add comment about need for trylock.
(scm_c_make_weak_table): Use the new scm_i_register_weak_gc_callback.
Previously this was the case because of a mistyped check for a
"HAVE_GC_TABLE_START_CALLBACK" symbol, whereas the symbol was actually
HAVE_GC_SET_START_CALLBACK. Anyway, it's better to call this after GC
anyway, as vacuuming might need to allocate weak links (on pre-7.3
libgc without GC_move_disappearing_link) or reallocate the backing
vector.
* libguile/finalizers.h:
* libguile/finalizers.c (scm_i_register_weak_gc_callback): New internal
helper, from weak-set.c.
Relative to the previous weak-set.c version, prefer the
finalizer-based implementation. Fix bug regarding confusion between
scm_before_gc_c_hook and scm_after_gc_hook. Fix bug regarding
referencing weak values outside of the alloc lock.
* libguile/weak-set.c (GC_move_disappearing_link): New stub.
GC_move_disappearing_link is only available in libgc 7.3.
(move_weak_entry): Use the new stub instead of ifdeffery.
(resize_set): Now that we run finalizers from a separate thread or
async, we can keep the lock while reallocating the set vector.
(do_vacuum_weak_set): For the same reason, always lock the set.
Remove implementation of scm_c_register_weak_gc_callback in preference
of the new copy in finalizers.c.
(scm_c_make_weak_set): Use the new scm_i_register_weak_gc_callback.
* libguile/gc.c: Remove shims for GC_get_heap_usage_safe,
GC_get_free_space_divisor, and GC_set_finalize_on_demand. Remove code
in the case in which we did not have GC_set_start_callback.
* libguile/posix.c (scm_fork): Issue a warning on a multithreaded fork.
* doc/ref/posix.texi (Processes): Add note about multithreaded fork.
* test-suite/tests/00-socket.test: Moved here, from socket.test, so as
to run before any threads are created.
* test-suite/Makefile.am: Adapt.
* libguile/posix.c (scm_fork): Issue a warning instead of an error on a
multithreaded fork.
* doc/ref/posix.texi (Processes): Add note about multithreaded fork.
* module/system/vm/trace.scm (build-prefix): New helper.
(print-application, print-return): Use the helper.
(trace-calls-to-procedure, trace-calls-in-procedure):
(trace-instructions-in-procedure, call-with-trace): Add #:max-indent
argument, defaulting to the terminal width less 40 characters.
* doc/ref/scheme-using.texi: Update `trace' docs.
Based on a patch by Nala Ginrut.
* module/language/tree-il/peval.scm (peval): Gensyms use whitespace as
an infix, not a dash. Helps gensym?-like procedures like those in the
unused lexical analysis.

module/ice-9/peg/string-peg.scm: update S-expression generators to use the
new *, +, ?, followed-by, and not-followed-by forms.
module/ice-9/peg/codegen.scm: remove the 'body' form in the PEG s-expression
representation.
* module/ice-9/peg.scm: move code out of here
* module/ice-9/peg/match-records.scm: remove this file
* module/ice-9/peg/using-parsers.scm: make a new module with utilities for
using parsers. It contains the code from both peg.scm and match-records.scm
* module/ice-9/peg/string-peg.scm: update to use new module
* module/ice-9/peg/codegen.scm: Make the PEG syntax extensible, and
move most of the current code generators to the new interface
* doc/ref/api-peg.texi: Document PEG extensions in the PEG Internals
section of the manual
* module/ice-9/peg/codegen.scm: peg-sexp-compile no longer knows about
string PEGs
* module/ice-9/peg.scm: add a new function peg-extended-compile that
calls peg-sexp-compile or peg-string-compile on its argument as
appropriate
* module/ice-9/peg/string-peg.scm: remove define-nonterm and make a simpler
macro called `define-sexp-parser' to make the PEG grammar
* module/ice-9/peg.scm: move define-nonterm macro to this file
* module/ice-9/peg/codegen.scm: move code to wrap a parser result nicely to
this file, under name `wrap-parser-for-users'
* module/ice-9/peg.scm (cg-generic-ret): Remove unused for-syntax
argument.
(peg-sexp-compile): Take the pattern as syntax directly, and use
syntax-case to destructure it and dispatch to the code generators.
(cg-and, cg-and-int, cg-or, cg-or-int): Refactor to operate on syntax
instead of on s-expressions.
(cg-body): Likewise; though this was a larger refactor.
(define-nonterm, peg-match): Adapt to peg-sexp-compile calling
convention change.
(peg-string-compile): Likewise, and just take the grammar as a syntax
object.
