* libguile/i18n.c (scm_nl_langinfo)[GROUPING]: Consider negative numbers
like `CHAR_MAX'. Reported by David Fang <fang@csl.cornell.edu>.
Fix suggested by Bruno Haible <bruno@clisp.org>.
* libguile/hashtab.c (scm_c_register_weak_gc_callback): New private
helper, arranges for a C function to be called with a SCM as an
argument, as long as the argument is reachable by GC.
(scm_make_weak_key_hash_table)
(scm_make_weak_value_hash_table)
(scm_make_doubly_weak_hash_table): Register a weak GC callback to
vacuum_weak_hash_table.
* libguile/gc.c (scm_gc): No need to take a mutex here. Don't run the
hook, the hook will run itself.
(scm_c_register_gc_callback): New private helper, registers a callback
the next time GC happens.
(system_gc_callback): Guile's internal callback that runs
scm_after_gc_c_hook, which itself queues a call to the after-gc-hook.
(scm_storage_prehistory): Queue up a call to system_gc_callback.
* module/web/uri.scm:
* module/web/server.scm (call-with-output-string*):
(call-with-output-bytevector*): Local procs to output to strings or
bytevectors, *and then close the port*. We can't make this change in
call-with-output-string because it would be incompatible.
* module/web/uri.scm (call-with-encoded-output-string, decode-string)
(uri-decode)
* module/web/server.scm (call-with-encoded-output-string): Use the new
helpers.
* module/ice-9/popen.scm (open-pipe*): Hack around the lack of an
after-gc hook, and pump the pipes guardian here in the procedure that
adds to the guardian.
* libguile/hashtab.c (vacuum_weak_hash_table): New helper, goes through
the entirety of a weak hash table, vacuuming dead entries.
(scm_hash_fn_create_handle_x): If when adding to a weak hash table, we
would trigger a rehash, vacuum the table first. The weak_bucket_assoc
would have only caught dead entries within one bucket.
Without this patch, the following code leaks:
(let lp ()
(call-with-output-string
(lambda (port)
(display "foo" port)))
(lp))
* module/rnrs/base.scm (define-proxy): New macro.
(raise, condition, make-error, make-assertion-violation,
make-who-condition, make-message-condition, make-irritants-condition):
Use it.
* doc/ref/autoconf.texi (Using Autoconf Macros): Switch example to use
PKG_CHECK_MODULES.
* doc/ref/libguile-linking.texi (A Sample Guile Main Program): Likewise,
and change from configure.in to configure.ac, and recommend
autoreconf.
* doc/ref/api-options.texi (Build Config):
* doc/ref/libguile-linking.texi (Linking Programs With Guile):
(A Sample Guile Main Program):
* doc/ref/libguile-smobs.texi (The Complete Example): Use pkg-config in
the examples instead of guile-config.
* doc/ref/history.texi (A Timeline of Selected Guile Releases): Update
the 2.0 release blurb.
* doc/ref/api-foreign.texi (Modules and Extensions):
* doc/ref/libguile-extensions.texi (A Sample Guile Extension):
* doc/ref/tour.texi (Linking Guile into Programs): Use
@value{EFFECTIVE-VERSION} instead of 2.0. Also fix sample extension
compilation line to include the Guile CFLAGS.
* doc/ref/goops.texi (Class Definition Protocol): Removed `*fixme
Need to insert something here about checking that the value is not
unbound'. It's a fine detail, and also I imagine there could be a
valid application that would choose to allow SCM_GOOPS_UNBOUND
values to escape through here.
* doc/ref/goops.texi (Method Definition): Unindent text about
define-method invoking add-method!.
(Method Definition Internals): Add @noindent's.
(Generic Function Invocation): Add intro text, and tidy up the tree.
* doc/ref/goops.texi (Class Redefinition): Deleted, with its material
all merged into later `Redefining a Class' and `Changing the Class of
an Instance' sections.
* doc/ref/goops.texi (Instance Creation Protocol): Rename from
`Customizing Instance Creation', and move before the more
complicated class definition stuff. Couple of very minor edits.
(Class Definition Protocol): Remove ensure-metaclass-with-supers
(too internal) and repeated material. Move class-redefinition
stuff to (existing) later section on that. Merge reference-like
material from `Customizing Class Definition' to here.
* doc/ref/goops.texi (The Metaobject Protocol): Simplify intro text.
Minor edits and simplifications throughout this section.
(Metaobjects and the Metaobject Protocol): Insert "default".
(Metaclasses): Renamed from `Terminology', and deleted the material
on CPL and accessors, which just duplicated what has already been
covered earlier in the chapter. Remove statements that confuse
whether "metaclass of" means "class of class of" or "class of
(something that is itself a class)". (I think it's actually the
latter.)
(Class Definition Protocol): Renamed from `Class Definition
Internals'.
* libguile/ports.c (scm_i_remove_port): Fix a case in which ports
explictly closed via close-port would leak their iconv_t data.
(scm_set_port_encoding_x): scm_i_set_port_encoding_x strdups its
argument, so we need to free the locale encoding of the incoming str.
* module/ice-9/binary-ports.scm: New module.
* module/Makefile.am: Add to makefile.
* module/rnrs/io/ports.scm: Re-export bindings from (ice-9 binary
ports). This will allow the compiler to not pull (rnrs) into its
included module set.
* libguile/numbers.c (log_of_shifted_double, log_of_exact_integer,
log_of_exact_integer_with_size, log_of_fraction): New internal static
functions used by scm_log and scm_log10.
(scm_log, scm_log10): Robustly handle large integers, large and small
fractions, and fractions close to 1. Previously, computing logarithms
of fractions close to 1 yielded grossly inaccurate results, and the
other cases yielded infinities even though the answer could easily fit
in a double. (log -0.0) now returns -inf.0+<PI>i, where previously it
returned -inf.0. (log 0) now throws a numerical overflow exception,
where previously it returned -inf.0. (log 0.0) still returns -inf.0.
Analogous changes made to `log10'.
* test-suite/tests/numbers.test (log, log10): Add tests.
