* module/ice-9/format.scm (format): Test to make sure an argument is a
number before applying `inf?' and `nan?' to it. Formerly, format
would call `inf?' and `nan?' on arguments that might be either a
number or a string, although those predicates should ideally throw an
exception when applied to non-number objects.
This leaves space for native code.
* libguile/objcodes.h (SCM_OBJCODE_NATIVE_CODE)
(SCM_SET_OBJCODE_NATIVE_CODE): Reserve the fourth word of objcode for
"native code", whatever that means.
* libguile/objcodes.c: Update a comment.
(make_objcode_by_mmap): Put the fd in the third word.
* libguile/objcodes.h (SCM_OBJCODE_TYPE_MMAP)
(SCM_OBJCODE_TYPE_BYTEVECTOR, SCM_OBJCODE_TYPE_SLICE)
(SCM_OBJCODE_TYPE_STATIC): Enumerate objcode types instead of
expressing them as flags.
(SCM_OBJCODE_TYPE): Type is held in bits 8-15.
(SCM_OBJCODE_FLAGS): Flags are now shifted by 16 bits, not 8.
(SCM_MAKE_OBJCODE_TAG): New helper.
* libguile/continuations.c (STATIC_OBJCODE_TAG):
* libguile/control.c (STATIC_OBJCODE_TAG):
* libguile/foreign.c (STATIC_OBJCODE_TAG):
* libguile/gsubr.c (STATIC_OBJCODE_TAG):
* libguile/smob.c (STATIC_OBJCODE_TAG):
* libguile/objcodes.c (make_objcode_by_mmap, scm_c_make_objcode_slice)
(scm_bytecode_to_objcode): : Use SCM_MAKE_OBJCODE_TAG.
* libguile/vm-i-system.c (variable-ref, variable-set, variable-bound?):
Check that the argument is actually a variable. Thanks to Kevin
Holmes for the report.
* libguile/vm-engine.c (vm_engine): Error handling down here.
* THANKS: Update.
* libguile/objcodes.c (make_objcode_by_mmap): Use
`scm_from_latin1_stringn', not `scm_from_locale_stringn', to display
the invalid cookie in the error case.
* doc/ref/misc-modules.texi (Formatted Output): Adapt ~f documentation
to indicate that the output will always have a decimal point. Thanks
to Fu-gangqiang for the report.
* THANKS: Update.
As a result `read-line' handles decoding and decoding errors the same
way as `scm_getc'. It's also simpler and free of `malloc' calls.
* libguile/rdelim.c (scm_do_read_line): Remove.
(scm_read_line): Rewrite as a loop that calls `scm_getc'.
* test-suite/tests/rdelim.test: New file.
* test-suite/Makefile.am (SCM_TESTS): Add `tests/rdelim.test'.
* libguile/ports.c (get_codepoint): Reset `pt->input_cd' upon failure.
If `pt->ilseq_handler' is `SCM_ICONVEH_QUESTION_MARK', then return a
question mark.
[failure]: Use `scm_encoding_error' when raising an error.
* test-suite/lib.scm (exception:encoding-error): Adjust regexp.
* test-suite/tests/ports.test ("string ports")["read-char, wrong
encoding, error", "read-char, wrong encoding, escape", "read-char,
wrong encoding, substitute"]: New tests.
* libguile/strings.c (scm_from_latin1_stringn): Directly return a narrow
string instead of going through `scm_from_stringn'.
(scm_to_latin1_stringn): Directly return a copy of STR's raw bytes when
it's narrow.
* libguile/ports.c (scm_i_set_port_encoding_x): Always initialize
PT->encoding to something non-NULL. This fixes callers of
`scm_encoding_error' such that they always pass a non-NULL encoding
name. Reported by Matei Conovici.
This is so that compiling the same code on environments with different
locale settings yields the same result.
* module/system/base/compile.scm (compile-file): When ENC if #f, default
to "UTF-8" instead of `(fluid-ref %default-port-encoding)'.
* doc/ref/api-evaluation.texi (Compilation): Document the default output
file name and default source file encoding for `compile-file' and
`guile-tools compile'.
* module/language/tree-il/fix-letrec.scm: Replace U+2019 with an ASCII
quote. The iconv implementation on FreeBSD would immediately notice
and bail out when reading it under a US-ASCII locale.
Thanks to Bruno Haible for his suggestions. See
<http://lists.gnu.org/archive/html/bug-libunistring/2010-09/msg00007.html>,
for details.
* libguile/ports.c (register_finalizer_for_port): Always register a
finalizer for PORT.
(finalize_port): Close ENTRY->input_cd and ENTRY->output_cd.
(scm_new_port_table_entry): Initialize the `input_cd' and `output_cd'
fields.
(utf8_to_codepoint): New function.
(get_codepoint): Rewrite to use `iconv' instead of libunistring.
(scm_i_set_port_encoding_x): Initialize the `input_cd' and `output_cd'
fields.
(update_port_lf): Move upward. Use `switch' instead of `if's.
* libguile/ports.h (scm_t_port)[input_cd, output_cd]: New fields.
* libguile/print.c (codepoint_to_utf8, display_string): New functions.
(display_character): Use `display_string'.
(write_combining_character): Likewise.
(iprin1): Use `display_string' instead of `scm_lfwrite_str', and
`display_character' instead of `scm_putc'.
(write_character): Likewise.
(write_character_escaped): New function.
* test-suite/tests/encoding-escapes.test ("display output
escapes")["Rashomon"]: Use lower-case escapes.
["fake escape"]: New test.
* libguile/numbers.c (scm_is_integer): Infinities are not integers, per
the R6RS.
(scm_even_p, scm_odd_p): Passing an infinity to even? or odd? is an
error.
* test-suite/tests/numbers.test ("integer?"): Adapt test.
("expt"): Add tests for +inf.0 and -inf.0 exponents.
* NEWS: Add NEWS entries.
* configure.ac: Check for GC_call_with_gc_active.
* libguile/threads.h (scm_i_thread): Remove "top", as it's not used.
* libguile/threads.c (with_gc_inactive, with_gc_active): Define shims to
GC_do_blocking and GC_call_with_gc_active.
(scm_i_init_thread_for_guile): Don't do thread base adjustment here,
do it in scm_i_with_guile_and_parent. The previous logic would never
be run.
(scm_i_with_guile_and_parent): If we enter Guile mode, leave it too.
Take care of adjusting the thread stack base here too. Also, call
with_gc_active.
(scm_without_guile): Refactor.
* libguile/private-options.h (SCM_HUNGRY_EOL_ESCAPES_P): New private
option.
* libguile/read.c: Define SCM_HUNGRY_EOL_ESCAPES_P, defaulting to #f.
(skip_intraline_whitespace): New helper.
(scm_read_string): If SCM_HUNGRY_EOL_ESCAPES_P,
skip_intraline_whitespace after an escaped EOL.
* test-suite/tests/reader.test ("read-options"): Add test.
