* module/sxml/upstream/SSAX.scm (ssax:handle-parsed-entity):
Interpret *DEFAULT* as being a default handler procedure for parsed
entities. Includes test.
* doc/ref/sxml.texi (SXML): Reorder and begin rewriting. Fix formatting
throughout, provide a new introduction, and the beginning of proper
SSAX documentation.
* doc/ref/sxml-match.texi:
* doc/ref/texinfo.texi:
* doc/ref/web.texi: Update references to new node names.
* module/ice-9/psyntax.scm (expand-body): Apply source-annotation to an
expression, not to the expression's compile-time environment.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/system/base/language.scm (<language>): Add 'for-humans?'
field, and export new 'language-for-humans?' predicate.
* doc/ref/compiler.texi (Compiler Tower): Document.
* module/language/assembly/spec.scm, module/language/bytecode/spec.scm,
module/language/glil/spec.scm, module/language/objcode/spec.scm,
module/language/tree-il/spec.scm, module/language/value/spec.scm:
Mark these languages as 'for-humans?'.
* module/language/ecmascript/base.scm (->boolean): Call `zero?' and
`nan?' only when X is a number.
* test-suite/tests/ecmascript.test ("compiler"): Add test case.
* module/oop/goops.scm, module/oop/goops/active-slot.scm,
module/oop/goops/composite-slot.scm, module/oop/goops/describe.scm:
Add a copyright line for Érick Gallesio. Mention the STk version
GOOPS was derived from. Remove mentions of the ‘COPYRIGHTS’ file.
Thanks to Karl Berry <karl@freefriends.org> for pointing it out, and
to Michael Djurfeldt <mikael@djurfeldt.com>.
* module/oop/goops/save.scm (write-component)
(write-component-procedure): Move definitions up so that syntax
definition is available when compiling the rest of the file.
* module/ice-9/command-line.scm (*usage*): Make usage of capitalization
and sentences consistent (lower-case and semicolons, as in ls
--help).
Be less specific about languages (Scheme is the default but not the
only language).
Document --language.
(load/lang, eval-string/lang): New helpers.
(compile-shell-switches): Parse a --language argument, and use it to
set (current-language).
* module/ice-9/boot-9.scm (current-language): New parameter.
* module/system/base/language.scm (*current-language*): Pull fluid from
parameter.
(current-language): Now a re-exported parameter.
* doc/ref/compiler.texi: Update reference from *current-language* fluid
to current-language parameter.
* module/system/base/compile.scm (compile-and-load):
* module/ice-9/top-repl.scm (top-repl): Default to the current language,
not to Scheme.
* module/ice-9/eval-string.scm:
* module/system/base/language.scm:
* module/system/repl/command.scm:
* module/system/repl/repl.scm: Update to use current-language parameter
and parameterize.
* module/ice-9/boot-9.scm (make-parameter): Add a docstring.
(fluid->parameter): New interface. Use it when turning port fluids
into parameters.
* doc/ref/api-scheduling.texi (Parameters): Deffn instead of defun for
make-parameter documentation. Add docs for fluid->parameter.
* module/ice-9/psyntax.scm (include): Like `load', interpret relative
paths as being relative to the file that does the `include'.
* doc/ref/api-evaluation.texi: Update docs.
* doc/ref/libguile-concepts.texi (Multi-Threading): Use functions in the
example instead of macros. Performance is really not a concern with
this interface, especially now that scm_car and scm_cdr are inline
functions.
* doc/ref/api-smobs.texi (Smobs): Document scm_new_smob and
scm_new_double_smob instead of the SCM_NEWSMOB / SCM_RETURN_NEWSMOB
family of macros.
* doc/ref/libguile-smobs.texi (Creating Smob Instances): Use
scm_new_smob.
* 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.scm: rename 'peg-sexp-compile' to
'compile-peg-pattern'
* module/ice-9/peg/codegen.scm: same
* module/ice-9/peg/string-peg.scm: same
