* libguile/posix-w32.c: Include gc.h and threads.h.
(proc_record): New structure tag.
<procs, proc_size>: New static variables.
(find_proc, proc_handle, record_proc, delete_proc): New utility
functions.
(start_child): Return value is now pid_t, as it is on Posix
platforms. Record the new process and returns its PID, instead of
returning a handle. Fix the recursive call.
(waitpid, kill, getpriority, setpriority, sched_getaffinity)
(sched_setaffinity): Look up the PID in the recorded subprocesses
before trying to open a process that is not our subprocess. Make
sure any open handle is closed before returning, unless it's our
subprocess.
* m4/mkstemp.m4: Remove.
* lib/mkstemp.c: Remove.
* lib/mkostemp.c: New file.
* m4/mkostemp.m4: New file.
* lib/Makefile.am:
* m4/gnulib-cache.m4:
* m4/gnulib-comp.m4: Remove mkstemp module, replace with mkostemp.
* libguile/fports.h:
* libguile/fports.c (scm_i_mode_to_open_flags): Factor out helper to
parse mode string to open flags.
(scm_open_file_with_encoding): Use the new helper.
* libguile/filesys.c:
(scm_i_mkstemp): Adapt to take optional second argument, being a mode
string. Use mkostemp.
(scm_mkstemp): Backwards compatible shim that calls scm_i_mkstemp.
* doc/ref/posix.texi:
* NEWS: Update.
* module/system/base/compile.scm (call-with-output-file/atomic): Pass
"wb" as mode, to cause O_BINARY to be added on MinGW.
* libguile/net_db.c (SCM_DEFINE_CONSTANT): New helper. Use it to
define constants and avoid the unneeded static variables that were
used before, named "sym_" but actually holding variables. Thanks to
Eli Zaretskii for the report.
* doc/ref/api-options.texi (Common Feature Symbols): Document the popen
feature.
* doc/ref/posix.texi (Pipes): Depend on the popen feature, not fork.
* libguile/posix.c (scm_init_posix): Add popen feature if we can.
* libguile/posix-w32.h:
* libguile/posix-w32.c (kill, waitpid, getpriority, setpriority)
(sched_getaffinity, sched_setaffinity): Add MinGW implementations.
Also, provides macros that on Posix hosts are in sys/wait.h, like
WIFEXITED and WTERMSIG.
(start_child): Add implementation.
* 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.
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/programs.c (try_parse_arity): New helper, to parse bytecode
to determine the minimum arity of a function in a cheaper way than
grovelling through the debug info. Should speed up all thunk? checks
and similar.
(scm_i_program_arity): Simplify.
* libguile/gsubr.h:
* libguile/gsubr.c (scm_i_primitive_arity):
* libguile/foreign.h:
* libguile/foreign.c (scm_i_foreign_arity):
* libguile/ports.c (scm_init_ports): Use the locale as the default
charset. After the switch to default GUILE_INSTALL_LOCALE=1, this
harmonizes the default port encoding with the installed locale.
* 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/filesys.c (scm_i_relativize_path): Canonicalize the file
names elements that we will be using as prefixes. Fixes the case
where a load path contains a relative file name: #19540.
* test-suite/tests/ports.test ("%file-port-name-canonicalization"): Add
tests that elements of the load path are canonicalized.
* 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/ports.c (scm_setvbuf): Fix bad use of SCM as a test value.
Actually all ports have read buffers, so we can remove the condition
entirely. Thanks Hydra for building in this way :)
* doc/ref/vm.texi (Top-Level Environment Instructions): Update
documentation.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump, sadly.
* module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* libguile/vm-engine.c (define!): Change to store variable in dst slot.
* module/language/tree-il/compile-cps.scm (convert):
* module/language/cps/compile-bytecode.scm (compile-function): Adapt to
define! change.
* module/language/cps/effects-analysis.scm (current-module): Fix define!
effects. Incidentally here was the bug: in Guile 2.2 you can't have
effects on different object kinds in one instruction, without
reverting to &unknown-memory-kinds.
* test-suite/tests/compiler.test ("regression tests"): Add a test.
* 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/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>.
* libguile/vm-engine.c (SP_REF_SLOT, SP_SET_SLOT): New defines.
(push, pop, mov, long-mov): Move full slots. Fixes 32-bit with
unboxed 64-bit stack values; before when shuffling these values
around, we were only shuffling the lower 32 bits on 32-bit platforms.
* libguile/vm-engine.c (VM_VALIDATE): Refactor some type-related
assertions to use a common macro.
(vector-length, vector-set!/immediate): Fix the proc mentioned in the
error message.
* doc/ref/posix.texi (Network Sockets and Communication):

only through the internals module.
* libguile/socket.c (scm_init_socket): Define TCP_NODELAY and TCP_CORK
if they are available.
* doc/ref/posix.texi (Network Sockets and Communication): Add
documentation.
* NEWS: Add entry.
* libguile/ports.c (scm_port_clear_stream_start_for_bom_write): Instead
of returning the BOM, take an optional buffer in which to write the
BOM. Return number of bytes written.
(port_clear_stream_start_for_bom_write): Remove.
(scm_i_write): Adapt scm_port_clear_stream_start_for_bom_write call.
(try_encode_char_to_iconv_buf, encode_latin1_chars_to_latin1_buf):
(encode_latin1_chars_to_utf8_buf, encode_latin1_chars_to_iconv_buf):
(encode_latin1_chars, encode_utf32_chars_to_latin1_buf):
(encode_utf32_chars_to_utf8_buf, encode_utf32_chars_to_iconv_buf):
(encode_utf32_chars, port_encode_chars): New helpers.

* test-suite/test-suite/lib.scm (exception:encoding-error): Add an
additional expected error string for `encoding-error'.

(scm_c_put_char, scm_c_put_string, scm_print_string): New public
functions. The plan is to move encoding to ports.c and out of
print.c.
* libguile/ports.c (UTF8_BUFFER_SIZE, ESCAPE_BUFFER_SIZE): New internal
defines.
(update_port_position): Take a position instead of a port. Update
callers.
(utf8_to_codepoint): Allow lengths that are larger than necessary.
(port_clear_stream_start_for_bom_write): Require that io_mode be
BOM_IO_TEXT to write a BOM.
(scm_fill_input): Add a related comment about BOM handling.
(scm_i_write): use BOM_IO_TEXT, at least for now.
(encode_escape_sequence, codepoint_to_utf8, utf8_to_codepoint)
(put_utf8_chars_to_iconv_port, put_latin1_chars_to_utf8_port)
(put_latin1_chars_to_iconv_port, put_utf32_chars_to_latin1_port)
(put_utf32_chars_to_utf8_port, put_utf32_chars_to_iconv_port): New
helpers.
