* libguile/posix.c (scm_getaffinity, scm_setaffinity): Clean up
docstrings. Obviously if you have the function, you don't need to be
told that you have it in the docstring.
* libguile/posix.c (scm_kill): Only provide if the host has `kill'. An
incompatible change on MinGW, where this function would work only if
the PID was the current PID, but that will be fixed by the next
process.
* configure.ac: Check for getuid, getgid, setuid, and setgid.
* libguile/posix.c (scm_getuid, scm_getgid, scm_setuid, scm_setgid):
Only provide Scheme functions if the OS provides these facilities.
(scm_geteuid, scm_getegid, scm_seteuid, scm_setegid): Provide if the
host has getuid, getgid, etc, instead of being in a MinGW guard.
* libguile/ports.c (scm_init_ports): Use the locale as the default
charset. This allows GUILE_INSTALL_LOCALE=1 to work properly,
harmonizing the default port encoding with the installed locale.
* meta/build-env.in: New file which sets up an environment that does not
inherit GUILE_LOAD_PATH / GUILE_LOAD_COMPILED_PATH (unless
cross-compiling).
* doc/ref/Makefile.am (autoconf-macros.texi):
* libguile/Makefile.am (snarf2checkedtexi):
* module/Makefile.am (ice-9/psyntax-pp.go):
* test-suite/standalone/Makefile.am (GUILE_INSTALL_LOCALE):
* am/guilec (.scm.go): Use build-env.
* configure.ac: Create build-env.
* libguile/load.c (load_thunk_from_path, try_load_thunk_from_file):
New functions.
(search_path): Simplify.
(scm_primitive_load_path, scm_init_eval_in_scheme): Use the new
functions to load compiled files.
* module/ice-9/boot-9.scm (load-in-vicinity): Skip invalid .go files.
Inspired by a patch from Jan Nieuwenhuizen <janneke@gnu.org>.
Based on a patch by Andy Stormont <astormont@racktopsystems.com>.
* configure.ac: Check for strtod_l.
* libguile/i18n.c (scm_locale_string_to_integer): Fix style.
(scm_locale_string_to_inexact): Check for strtod_l.
* libguile/bytevectors.c (sym_big, sym_little): Rename from scm_sym_big
and scm_sym_little, and don't use the snarf mechanism as we need to
initialize this value eagerly in case the C API is used before the
Scheme module is loaded.
(scm_bootstrap_bytevectors): Initialize the endianness symbols here.
* libguile/r6rs-ports.c (scm_register_r6rs_ports): Register the R6RS
port kinds here, for the same reason.
* libguile/conv-integer.i.c (SCM_FROM_TYPE_PROTO):
* libguile/conv-uinteger.i.c (SCM_FROM_TYPE_PROTO): Fix a big in which
scm_from_int64 and scm_from_uint64 on a 32-bit platform leaked memory
if they needed to allocate a bignum. Fixes#20079.
* libguile/smob.c (clear_smobnum): New helper.
(finalize_smob): Re-set the smobnum to the "finalized smob" type
before finalizing. Fixes#19883.
(scm_smob_prehistory): Pre-register a "finalized smob" type, which has
no mark procedure.
* test-suite/standalone/test-smob-mark-race.c: New file.
* test-suite/standalone/Makefile.am: Arrange to build and run the new
test.
* libguile/i18n.c (str_upcase, str_downcase, str_upcase_l)
(str_downcase_l): Remove unused inline functions. Based on a patch by
Pedro Aguilar <paguilar@paguilar.org>. Fixes#19172.
* libguile/bytevectors.c (bytevector_large_set): Fix computation of
value size in words.
* test-suite/tests/bytevectors.test: Add test.
Thanks to Ben Rocer <fleabyte@mail.com> for the bug report and fix.

* libguile/foreign.c (cif_to_procedure): Add 'return_errno' argument.
Store its boolean value in the object table of the generated program.
(scm_i_foreign_call): If the stored 'return_errno' flag is true, then
clear 'errno' before the call, save it after the call, and return it
as a second return value.
(pointer_to_procedure): New static function.
(scm_pointer_to_procedure_with_errno): New C API function, implemented
in terms of 'pointer_to_procedure'.
(scm_pointer_to_procedure): Reimplement in terms of
'pointer_to_procedure', no longer bound to "pointer->procedure". See
below.
(scm_i_pointer_to_procedure): New C function bound to
"pointer->procedure" which now accepts the optional #:return-errno?
keyword argument, implemented in terms of 'pointer_to_procedure'.
(k_return_errno): New keyword #:return-errno?.
* libguile/foreign.h (scm_pointer_to_procedure_with_errno): Add prototype.
* doc/ref/api-foreign.texi (Dynamic FFI): Adjust documentation.
This assumption does not hold on systems that use the LLP64 data model.
Partially fixes <https://debbugs.gnu.org/22406>.
Reported by Peter TB Brett <peter@peter-b.co.uk>.
* libguile/numbers.h (scm_t_inum): Move here from numbers.c, and change
to be equivalent to 'long' (formerly 'scm_t_signed_bits').
(SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Define based on
SCM_I_FIXNUM_BIT instead of SCM_T_SIGNED_BITS_MAX.
(SCM_I_INUM): Adjust definitions to return a 'scm_t_inum', and avoiding
the assumption that SCM_UNPACK returns a 'long'.
* libguile/numbers.c (scm_t_inum): Move definition to numbers.h.
Verify that 'scm_t_inum' fits within a SCM value.
(scm_i_inum2big): Remove preprocessor code that forced a compile error
unless sizeof (long) == sizeof (void *).
* libguile/vm-i-scheme.c (_CX): For fixnum assembly functions, choose
the register size based on SCM_I_FIXNUM_BIT instead of SIZEOF_VOID_P.
(ASM_MUL, "ash", "vector-ref", "vector-set", BV_FIXABLE_INT_REF)
(BV_INT_REF, BV_FLOAT_REF, BV_FIXABLE_INT_SET, BV_INT_SET)
(BV_FLOAT_SET): Use 'scm_t_inum' for fixnums instead of
'scm_t_signed_bits'.
Fixes <https://debbugs.gnu.org/22152>.
Reported by Iwan Aucamp <aucampia@gmail.com>.
* libguile/threads.c (fat_mutex_unlock): Avoid repeatedly decrementing
m->level and changing the owner of the mutex when 'block_self' returns
EINTR. Unblock asyncs before calling scm_syserror. Refactor the code
to clarify the EINTR loop, and to make it more apparent that the async
blocks and unblocks are balanced.
For a long time the API failed to reach consensus among maintainers.

and <https://lists.gnu.org/archive/html/guile-devel/2014-04/msg00069.html>.
This revert intends to break the deadlock and help further discussion to
take place with less pressure.

* doc/ref/Makefile.am (guile_TEXINFOS): Adjust accordingly.
* doc/ref/api-control.texi, doc/ref/api-smobs.texi,
doc/ref/api-utility.texi, doc/ref/guile.texi,
doc/ref/libguile-concepts.texi, doc/ref/libguile-program.texi:

in <https://lists.gnu.org/archive/html/guile-user/2015-11/msg00026.html>.
* libguile/socket.c (scm_getsockopt, scm_setsockopt): Remove code that
incorrectly assumed that the argument for SO_SNDBUF and SO_RCVBUF
options was of type 'size_t'. Both the Linux and POSIX documentation
indicates that the argument is of type 'int', as is the case for most
options.
Suggested by Mike Gran <spk121@yahoo.com>.
* libguile/srfi-14.i.c: Regenerate for Unicode 8.0.0,
<ftp://unicode.org/Public/UNIDATA/UnicodeData.txt> with SHA256
38b17e1118206489a7e0ab5d29d7932212d38838df7d3ec025ecb58e8798ec20.
* libguile/strports.c (st_resize_port): Check that 'new_size' fits in a
size_t.
(st_end_input): Improve code clarity.
(st_seek): Check for overflow during computation of target position.
Check for invalid 'whence' argument. Resize the port when seeking to
a position beyond the end of the buffer. Check for overflow during
computation of new buffer size when resizing the port.
Fixes <http://bugs.gnu.org/20302>.
Reported by David Kastrup <dak@gnu.org>.
* libguile/r6rs-ports.c (bip_end_input): New static function.
(initialize_bytevector_input_ports): Register it.
(bip_seek): Rewrite to handle putback buffers, based on st_seek from
strports.c.
* libguile/Makefile.am (chknew-E chknew-SIG): Anchor the end of the
signal/error name pattern to only match alphanumeric symbols.
* libguile/cpp-SIG.syms (SIGEV_MAX_SIZE, SIGEV_NONE): Remove.
(SIGEV_PAD_SIZE, SIGEV_SIGNAL, SIGEV_THREAD): Likewise.
(SIGEV_THREAD_ID): Likewise.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
Fixes <http://bugs.gnu.org/21114>.
* libguile/Makefile.am (chknew-E chknew-SIG): Remove the line
continuation after the targets, and include numbers in the
recipe's signal/error regexp to catch names like E2BIG.

When encountering the #!r6rs directive, apply the appropriate reader
settings to the port.
* libguile/read.scm (read-string-as-list): New helper procedure.
(scm_read_shebang): Set reader options implied by the R6RS syntax
upon encountering the #!r6rs directive.
* test-suite/tests/reader.test (per-port-read-options): Add tests for
the #!r6rs directive.
* libguile/foreign.c (scm_sizeof): Make sure the overall size is a
multiple of the alignment of the structure.
* test-suite/tests/foreign.test: Test size of { double, int8 }.
Although popular compilers allow it as long as the expression is of type
void, it violates C99 and some compilers choke on it.
* libguile/numbers.c (scm_euclidean_divide, scm_floor_divide)
(scm_ceiling_divide, scm_truncate_divide, scm_centered_divide)
(scm_round_divide): Don't use the return statement with an expression
from functions with return type void.
* libguile/libguile-2.0-gdb.scm (make-scm-pretty-printer-worker):
(%scm-pretty-printer): Refactor to avoid printing all struct / array
fields by hinting these as arrays. The resulting print is not as
faithful to the original data, but that's probably OK.
* libguile/goops.c (is_accessor_method, scm_compute_applicable_methods):
Fix regression from 51f66c9120 (2009).
Accessor methods are added on each subclass on which the slot is
present; therefore if a subclass doesn't have a method, then the
methods doesn't apply. Truly fixes#17355, unlike
583a23bf10.
* module/oop/goops.scm (compute-cmethod, compute-getter-method)
(compute-setter-method): Revert earlier changes.
* test-suite/tests/goops.test ("accessor slots"): Update for new
expectations, in agreement with Guile 1.8.
