* module/web/http.scm ("Cache-Control"): Value for `max-stale' is
optional. Strict validation for value-less directives (`no-store',
etc.). String values optional for "cache-extension" directives.
* test-suite/tests/web-http.test: Value for `max-stale' is optional.
* doc/ref/api-control.texi (begin): Update to distinguish between
splicing begin and sequencing begin.
* module/ice-9/psyntax.scm (expand-expr): Add a back-compatibility shim
for `(begin)'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* test-suite/tests/syntax.test: Update to run illegal (begin) test only
if we are not including deprecated features.
* module/language/tree-il/peval.scm (singly-valued-expression?): New
helper.
(truncate-values): Use the helper.
(make-operand): Minor refactor.
(set-operand-residual-value!): Try to undo the effects of (values
FOO), if the continuation will check itself for the correct number of
values.
(peval): Fold helpers into fold-constant. Add a constant-expression?
case for (values FOO). Add a new context: "values", for contexts in
which multiple values are allowed, either because of being in a tail
context relative to a function, or because of let-values. "value" is
now for single values. Don't visit operands for "values", as their
binding form truncates to one value. Add a case to fold (values ...)
forms. Fix folding of (lambda), to process the cases in values
context instead of tail context (which could have been "value", which
would cause the procedure to truncate).
* module/ice-9/ftw.scm (file-system-fold): Fix reference to STAT instead
of ST.
(scandir)[enter?]: Change the argument name to `dir', to avoid
confusion.
[skip]: Return RESULT, not #f.
* module/ice-9/ftw.scm (scandir)[leaf]: Only add NAME when RESULT is a
pair.
[down]: Ignore RESULT.
Start with #f instead of the empty list.
* test-suite/tests/ftw.test ("scandir")["flat file"]: New test.
* doc/ref/misc-modules.texi (File Tree Walk): Update `scandir'
documentation accordingly.
* module/ice-9/deprecated.scm: Add alias for $expt. $expt was removed
in commit 6fc4d0124d but no deprecated
alias was added in ad79736c68 like for
all the other deprecated $sin, $cos, ... functions.
Suggested by Nala Ginrut <nalaginrut@gmail.com>.
* module/ice-9/ftw.scm (scandir): New procedure.
* test-suite/tests/ftw.test ("scandir"): New test prefix.
* doc/ref/misc-modules.texi (File Tree Walk): Document `scandir'.
* module/ice-9/ftw.scm (file-system-fold): Add an optional `stat'
parameter. Use it instead of `lstat'. Handle the case where (STAT child)
fails.
(file-system-tree): Likewise, and pass it to `file-system-fold'.
* doc/ref/misc-modules.texi (File Tree Walk): Update the documentation
of these functions.
This is a temporary workaround for the 2.0 stable series. The next
stable series should have an implicit `setlocale (LC_ALL, "")' call,
which will make this unnecessary.
* libguile/feature.c (progargs_fluid): Rename to...
(scm_program_arguments_fluid): ... this. Update users.
* libguile/feature.h (scm_program_arguments_fluid): New internal
declaration.
* libguile/init.c (invoke_main_func): Call
`scm_i_set_boot_program_arguments' instead of
`scm_set_program_arguments'.
* libguile/script.c (locale_arguments_to_string_list,
scm_i_set_boot_program_arguments): New functions.
(scm_compile_shell_switches): Use `locale_arguments_to_string_list'.
* libguile/script.h (scm_i_set_boot_program_arguments): New internal
declaration.
* test-suite/standalone/Makefile.am (check_SCRIPTS, TESTS): Add
`test-command-line-encoding'.
* test-suite/standalone/test-command-line-encoding: New file.
* libguile/foreign.c: Use `alignof_type' instead of `alignof'; the
latter was removed from Gnulib's <alignof.h> in
408e170e3ae81f73fb65686c5834693d89a96594 (Nov. 1 2011).
* libguile/vm-i-scheme.c: Likewise.
* module/ice-9/ftw.scm (file-system-fold, file-system-tree): New
procedures.
* test-suite/tests/ftw.test (%top-srcdir, %test-dir): New variables.
("file-system-fold", "file-system-tree"): New test prefixes.
* doc/ref/misc-modules.texi (File Tree Walk): Document
`file-system-tree' and `file-system-fold'.
* module/ice-9/session.scm: #:keyword-ify the define-module form, and
export apropos-hook.
(apropos-hook): New hook.
(apropos, apropos-fold): Run the apropos-hook.
* libguile/ports.c (scm_init_ports): Export the port fluids to Scheme,
temporarily.
* module/ice-9/boot-9.scm (fluid->parameter): Turn `current-input-port'
et al into srfi-39 parameters, backed by the exported fluids, then
remove the fluids from the guile module.
(%cond-expand-features): Add srfi-39.
* module/srfi/srfi-39.scm: Re-export features from boot-9.
* test-suite/tests/parameters.test: Add tests.
* configure.ac: Add checks for GC_gcollect_and_unmap and
GC_get_unmapped_bytes.
* libguile/gc-malloc.c (scm_realloc): GC_gcollect() if we don't have
GC_gcollect_and_unmap.
* libguile/gc.c (GC_get_heap_usage_safe): Likewise, don't
GC_get_unmapped_bytes if the function doesn't exist.
Reported by Cédric Cellier <rixed@happyleptic.org>.
* module/language/tree-il/peval.scm (truncate-values): New procedure.
(make-operand): Call `truncate-values' SOURCE.
* test-suite/tests/tree-il.test ("partial evaluation"): New tests for
multiple value truncation.
* test-suite/tests/asm-to-bytecode.test (%objcode-cookie-size)
(test-target): The objcode version embedded in the cookie is not an
effective version, so elide it from the test.
* libguile/ports.h (struct scm_t_port): Make the lock into a pointer
field instead of an inline field. It should be possible to make
unlocked ports by having a NULL lock field.
(scm_c_lock_port, scm_c_try_lock_port): Return the mutex if the port
was actually locked.
(scm_c_unlock_port): Remove.
* libguile/ports.c (scm_c_make_port_with_encoding): For now, leave
`lock' set to 0.
Change scm_c_lock_port callers to pay attention to the new API.
* libguile/print.c (scm_write, scm_display): Fix call to
dynwind-lock-port for ports-with-print-states.
* module/web/uri.scm (parse-authority): Allow empty authorities, so that
we accept URIs of the form, file:///etc/hosts.
* test-suite/tests/web-uri.test ("string->uri"): Add tests.
* libguile/ports.h:
* libguile/ports.c (scm_current_warning_port)
(scm_set_current_warning_port): New functions, wrapping the Scheme
parameter.
* module/ice-9/boot-9.scm (current-warning-port): New parameter,
defining a port for warnings.
* module/ice-9/boot-9.scm (<parameter>, make-parameter, parameter?)
(parameter-fluid, parameter-converter, parameterize): New top-level
bindings, implementing SRFI-39 parameters. Currently,
current-input-port and similar procedures are not yet parameters.
* test-suite/Makefile.am:
* test-suite/tests/parameters.test: Add tests, taken from srfi-39
tests.
* libguile/private-options.h (SCM_PRINT_ESCAPE_NEWLINES_P):
* libguile/print.c: Add new escape-newlines print option, defaulting to
on.
(write_character): For newlines, if SCM_PRINT_ESCAPE_NEWLINES_P, then
print them as \n.
(scm_init_print): Refactor print options initialization.
* module/system/repl/command.scm (language): Set the
*current-language*.
* module/system/repl/repl.scm (start-repl): Create a new dynamic scope
for *current-language*.
* libguile/numbers.c (custom_gmp_malloc, custom_gmp_realloc,
custom_gmp_free): New static functions used by GMP for allocation.
These are just wrappers for scm_malloc, scm_realloc, and free.
(scm_init_numbers): If scm_install_gmp_memory_functions is nonzero,
use mp_set_memory_functions to configure GMP to use
custom_gmp_{malloc,realloc,free} for memory allocation.
(scm_bigprint): Ask gmp for the function used to deallocate the string
returned by mpz_get_str.
* libguile/numbers.h: Declare scm_install_gmp_memory_functions.
* libguile/guile.c: When running the Guile binary, install the
gmp_memory_functions.
Based on a patch by Mark H Weaver <mhw@netris.org>.
* libguile/gc-malloc.c (scm_realloc): Call the new
scm_gc_register_allocation() here. If we have to collect, do a
GC_gcollect_and_unmap.
* libguile/gc.c (scm_gc_register_allocation): Add a routine to track
steady-state mallocation, and cause gc to run if there is a high
mallocation rate.
(adjust_gc_frequency): Reset the bytes-until-GC countdown timer.
