Fixes <http://bugs.gnu.org/13848>.
Reported by Jan Schukat <shookie@email.de>.
* configure.ac: Rename `HAVE_FORK' conditional to `BUILD_ICE_9_POPEN'.
Set it when both $enable_posix and $ac_cv_func_fork are true.
* libguile/posix.c (scm_init_posix): Add the `fork' feature.
* doc/ref/api-options.texi (Common Feature Symbols): Add `fork'.
* doc/ref/posix.texi (Pipes): Add footnote mentioning the `fork'
feature.
* module/Makefile.am (SCRIPTS_SOURCES): Make `scripts/autofrisk.scm' and
`scripts/scan-api.scm' conditional on `BUILD_ICE_9_POPEN'.
* test-suite/tests/popen.test (if-supported): New macro.
Wrap body in `if-supported'.
* libguile/posix.c (scm_execl, scm_execlp, scm_execle)
(scm_open_process): Remove casts for ancient mingw.
(scm_utime): If we fall back to utime, assert that flags is 0.
(scm_getlogin): Rely on gnulib.
* libguile/posix.c: Reorder includes to fix mingw include-order
problem. Remove ttyname shims; gnulib is the place to fix that.
Remove winsock2 include, as gnulib seems to handle that OK. Rely on
the new pipe-posix gnulib module. Don't bother shimming getlogin, etc
on mingw; gnulib is the place for shims.
* 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_open_process): Return the ports as values
instead of calling out to Scheme again to make-rw-port. This
function is private to (ice-9 popen).
* module/ice-9/popen.scm (open-pipe*): Adapt to change.
Fixes <http://bugs.gnu.org/12477>.
Reported by lin ray <lin.wei.ray@gmail.com>.
* configure.ac: Define the `HAVE_FORK' Automake conditional.
* module/Makefile.am (ICE_9_SOURCES): Add `ice-9/popen.scm' only when
HAVE_FORK.
* libguile/posix.c (scm_init_posix): Register `scm_init_popen' only when
HAVE_FORK.
* libguile/posix.c (scm_open_process): Rewrite in C, so as to avoid
allocations and other calls that are not async-signal-safe.
(scm_init_popen, scm_init_posix): Register popen extension.
* module/ice-9/popen.scm: Load the popen extension, to get open-process.
* libguile/posix.c (scm_tmpfile): Fix to actually close the new
tmpfile, causing its deletion, while keeping an fd to the file open.
Fixes a leak both in memory and disk space on POSIX systems; MINGW
systems will leak however. A FIXME for later.
* configure.ac: Check for <sched.h>.
* libguile/posix.c [HAVE_SCHED_H]: Include <sched.h>, for
`sched_setaffinity' & co.
Reported by Marco Maggi <marco.maggi-ipsu@poste.it>.
* libguile/arrays.c (scm_i_read_array):
* libguile/backtrace.c (display_backtrace_body):
* libguile/filesys.c (scm_readdir)
* libguile/i18n.c (chr_to_case):
* libguile/ports.c (register_finalizer_for_port):
* libguile/posix.c (scm_nice):

set-but-unused vars. Thanks to Douglas Mencken for the report.
* libguile/numbers.c (scm_log, scm_exp): Fix a few #if cases that should
be #ifdef.
* libguile/ports.c (scm_i_set_default_port_encoding,
scm_i_default_port_encoding): New function. Replace
`scm_i_set_port_encoding_x' and `scm_i_get_port_encoding' with
PORT == SCM_BOOL_F.
(scm_i_set_port_encoding_x): Assume PORT is a port.
(scm_i_get_port_encoding): Remove.
(scm_port_encoding): Adjust accordingly.
(scm_new_port_table_entry): Use `scm_i_default_port_encoding'.
* libguile/ports.h (scm_i_get_port_encoding): Remove declarations.
(scm_i_default_port_encoding, scm_i_set_default_port_encoding): New
declarations.
* libguile/posix.c (setlocale): Use `scm_i_set_default_port_encoding'.
* libguile/posix.c (scm_total_processor_count,
scm_current_processor_count): New functions.
* libguile/posix.h (scm_total_processor_count,
scm_current_processor_count): New declarations.
* test-suite/tests/posix.test ("nproc"): New test prefix.
* doc/ref/posix.texi (Processes): Document `total-processor-count' and
`current-processor-count'.
* doc/ref/posix.texi (Processes): Add cross-reference from `setaffinity'
and `getaffinity' to the corresponding node in the glibc manual.
* libguile/posix.c (scm_getaffinity, scm_setaffinity): Likewise.

`sched_getaffinity'.
* doc/ref/posix.texi (Processes): Document `getaffinity' and

* libguile/posix.c (cpu_set_to_bitvector,
scm_getaffinity)[HAVE_SCHED_GETAFFINITY]: New functions.

* libguile/posix.h (scm_getaffinity, scm_setaffinity): New declarations.
* test-suite/tests/posix.test ("affinity"): New test prefix.
* libguile/posix.c:
* libguile/posix.h:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_cuserid): Deprecate cuserid, as it only
returns 8 bytes of a user's login.
* doc/ref/posix.texi: Remove cuserid from docs.
* libguile/threads.c:
* libguile/posix.c: Change a couple #if HAVE_FOO to #ifdef HAVE_FOO to
pacify -Wundef. Some vars are defined or not, whereas some are always
defined to 0 or 1. The inconsistency is unfortunate.
* libguile/posix.c (scm_utime): Use "#ifdef HAVE_UTIMENSAT", not "#if
HAVE_UTIMENSAT". Fix GCC warning around call to utimensat(2):
"passing argument 3 of 'utimensat' from incompatible pointer type".
* test-suite/tests/posix.test ("utime"): New test prefix.
* libguile/posix.h:
* libguile/posix.c (scm_utime): Add optional nanosecond arguments. This
is an incompatible change on the C level, but it's unlikely people are
using this POSIX wrapper function, because they would just use the
POSIX function directly. Hopefully, anyway.
* module/system/base/compile.scm (call-with-output-file/atomic):
Propagate source timestamps to targets with nanosecond precision, if
available. Fixes build on systems with ext4 filesystems.
* libguile/filesys.c (scm_stat2scm):
* module/ice-9/posix.scm (stat:atimensec, stat:mtimensec)
(stat:ctimensec): Add three new elements to Scheme stat structures,
for nanosecond-level timestamps.
* configure.ac: Add checks for utimensat, and for nanosecond fields in
struct stat. We should switch to using Gnulib things for these,
though.
* doc/ref/posix.texi (File System): Add documentation for utime's
additional arguments, and nanosecond stat timestamp accessors.
* configure.ac: Check availability of getsid() C library call.
* libguile/posix.c (scm_getsid): New primitive.
* libguile/posix.h: Declaration for new primitive.
Ports are given two additional properties: a character encoding and
a conversion failure strategy. These properties have getters and setters.
The new properties are used to convert any locale text to/from the
internal representation of strings.
If unspecified, ports use a default value. The default value of these
properties is held in a fluid. The default character encoding can be
modified by calling setlocale.
ISO-8859-1 is treated specially. Since it is a native encoding of
strings, it can be processed more quickly. Source code is assumed to be
ISO-8859-1 unless otherwise specified. The encoding of a source code
file can be given as 'coding: XXXXX' in a magic comment at the top of a
file.
The C functions that deal with encoding often use a null pointer
as shorthand for the native Latin-1 encoding, for efficiency's sake.
