* Presumes signal handler return voidMichael Gran2022-10-141-17/+7
| | | | | | | | | | Since Guile requires a C99 compiler, we can rely on signal handlers returning void, not int. * configure.ac: remove AC_TYPE_SIGNAL * libguile/scmsigs.c (SIGRETTYPE): remove SIGRETTYPE (take_signal): returns void (scm_sigaction_for_thread): presumes handlers return void

* 'pipe' now takes an optional 'flags' parameter.Ludovic Courtès2022-09-192-7/+47
| | | | | | | | | | | | | This is the same strategy as used for the 'accept4' bindings introduced in 6e0965104c579431e5a786b60e1a964a112c73b8. * libguile/posix.c (scm_pipe): Rename to... (scm_pipe2): ... this. Add an optional 'flags' parameter and honor it. (scm_pipe): Rewrite as a call to 'scm_pipe2'. * libguile/posix.h (scm_pipe2): New declaration. * test-suite/tests/posix.test ("pipe"): New tests. * configure.ac: Look for 'pipe2'. * NEWS: Update.

| | | | | | | | | | Fixes <https://bugs.gnu.org/55596>. Reported by Hugo Nobrega <hugonobrega@ic.ufrj.br> and Jack Hill <jackhill@jackhill.us>. * libguile/posix.c (start_child): Close OUT only if it's greater than 2. * test-suite/tests/posix.test ("system*")["exit code for nonexistent file"] ["https://bugs.gnu.org/55596"]: New tests.

* Allow null bytes in UNIX sockets.Liliana Marie Prikler2022-06-161-6/+14
| | | | | | | | | | | | | | | | | | | | | | The current socket address constructors all assume, that there are no null bytes in the socket path. This assumption does not hold in Linux, which uses an initial null byte to demarcate abstract sockets and ignores all further null bytes [1]. [1] https://www.man7.org/linux/man-pages/man7/unix.7.html * libguile/sockets.c (scm_fill_sockaddr)[HAVE_UNIX_DOMAIN_SOCKETS]: Use scm_to_locale_stringn to construct c_address. Use memcpy instead of strcpy and calculate size directly instead of using SUN_LEN. (_scm_from_sockaddr): Copy the entire path up to the limits imposed by addr_size. * test-suite/tests/00-socket.test: ("make-socket-address"): Add case for abstract unix sockets. ("AF_UNIX/SOCK_STREAM"): Add abstract socket versions of bind, listen, connect and accept. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* 'connect' handles EAGAIN like EINPROGRESS.Ludovic Courtès2022-06-161-1/+1
| | | | | | * libguile/socket.c (scm_connect): Handle EAGAIN the same way as EINPROGRESS (connect(2) returns EAGAIN for Unix-domain sockets and socketpairs).

* build: When cross-compiling, get type sizes of the target system.Ludovic Courtès2022-02-281-16/+16
| | | | | | | | | | | | | | | Fixes <https://issues.guix.gnu.org/54198>. As noted in the comment at the top, 'SIZEOF_TYPE' must be used instead of 'sizeof (TYPE)' to support cross-compilation. The regression was introduced in 5e5afde06fd9dd0992294d6c7dc9f9966c0caa37 but only became apparent with 717e787da6ae75bbaa53139c0ef3791cd758a9d8. * libguile/gen-scmconfig.c (main): Replace uses of 'sizeof' by references to the SIZEOF_* macros. * configure.ac: Add 'AC_CHECK_SIZEOF' call for 'intmax_t'.
* Align argument type of scm_to_wchar with its declaration.Mikael Djurfeldt2022-02-101-1/+1
| | | | | * libguile/numbers.c (scm_from_wchar): Change argument type from wchar_t to scm_t_wchar which is the argument type in numbers.h.
* Align return type of scm_to_wchar with its declaration.Mikael Djurfeldt2022-02-101-1/+1
| | | | | * libguile/numbers.c (scm_t_wchar): Change return type from wchar_t to scm_t_wchar which is the return type in numbers.h.
* 'string->symbol' avoids copying the underlying string.Ludovic Courtès2022-02-071-3/+9
| | | | | | * libguile/strings.c (scm_i_make_symbol): Reuse NAME's stringbuf unless it's mutable or NAME starts at a non-zero offset or has a different length.
* Update unicode tables to Unicode 14.0.0; initial charsets immutableAndy Wingo2022-02-063-9993/+5182
| | | | | | | | | | | | | | | | | | | | | * libguile/srfi-14.i.c: Update from Unicode 14.0.0. * libguile/unidata_to_charset.pl (compute): Write arrays as static const data, to avoid polluting the namespace and to avoid adding these to the GC root set. * libguile/srfi-14.c (SCM_CODEPOINT_F_IMMUTABLE): New flag. (scm_charset_is_immutable): New internal predicate. (SCM_VALIDATE_MUTABLE_CHARSET): New internal validator. (cs_full_ranges, cs_full_ranges_len): Re-express as separate ranges and len, because the ranges pointer in scm_t_char_set is mutable. (scm_char_set_unfold_x, scm_list_to_char_set_x) (scm_string_to_char_set_x, scm_char_set_filter_x) (scm_i_ucs_range_to_char_set, scm_char_set_adjoin_x) (scm_char_set_delete_x, scm_char_set_complement_x) (scm_char_set_unfold_x, scm_char_set_intersection_x) (scm_char_set_difference_x, scm_char_set_xor_x): Require mutable charsets. (define_charset): Add immutable flag. (scm_init_srfi_14): Adapt initial charset definitions.
* Deprecate symbol properties.Ludovic Courtès2022-02-046-68/+76
| | | | | | | | | | | | | | | | | | | | | | * libguile/strings.c (scm_i_make_symbol): Remove 'props' argument. Use 3 words instead of 'scm_double_cell'. * libguile/strings.h: Adjust accordingly. * libguile/symbols.c (scm_i_str2symbol, scm_i_str2uninterned_symbol): Likewise. (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x, scm_symbol_pset_x): Move to... * libguile/deprecated.c: ... here. Rewrite in terms of object properties. (symbol_function_slot, symbol_property_slot): New variables. * libguile/symbols.h (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC) (SCM_SYMBOL_PROPS, SCM_SET_SYMBOL_PROPS) (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x) (scm_symbol_pset_x): Move to... * libguile/deprecated.h: ... here. Mark declarations as 'SCM_DEPRECATED'. * module/system/base/types.scm (cell->object): Remove 'props' field for %TC7-SYMBOL. * doc/ref/api-data.texi (Symbol Props): Remove. * NEWS: Update.
* Remove unused 'scm_i_c_make_symbol'.Ludovic Courtès2022-02-032-14/+0
| | | | | * libguile/strings.c (scm_i_c_make_symbol): Remove. * libguile/strings.h (scm_i_c_make_symbol): Remove declaration.

* Have log and log10(real nan) return real nan regardless of signDaniel Llorens2022-01-131-8/+9
| | | | | | * libguile/numbers.c (log_of_shifted_double, scm_log10): Avoid complex extension when the argument is a real nan. * test-suite/tests/numbers.test: Tests for nans of either sign.
* Don't use HAVE_COPYSIGN in libguile/numbers.cDaniel Llorens2022-01-131-4/+0
| | | | | * libguile/numbers.c (icmplx2str): As stated. copysign() is required by C99 and already used without guards elsewhere in this file.
* Simplify scm_abs for the real caseDaniel Llorens2022-01-131-11/+1
| | | | | | * libguile/numbers.c (scm_abs): As stated. When x is a nan with the sign bit set, this changes the behavior of (magnitude x) back to what it was in 3.0.7, to clear that bit.

* Optimize bignum add to avoid temporary allocationsAndy Wingo2022-01-131-26/+106
| | | | | | | * libguile/integers.c (do_add_1, do_add, do_sub_1, do_sub, do_cmp): New helpers. (scm_integer_add_zi): (scm_integer_add_zz): Use new helpers.
* Avoid bignum clone in scm_integer_sub_zzAndy Wingo2022-01-131-2/+10
| | | | | | * libguile/integers.c (scm_integer_abs_z): Just call scm_integer_negate_z if negation is needed. (scm_integer_sub_zz): Use mpz_sub instead of cloning bignum.
* Start to optimize scm_integer_sub_izAndy Wingo2022-01-131-1/+13
| | | | * libguile/integers.c (scm_integer_sub_iz): Avoid cloning bignum.
* Less pessimal scm_integer_sub_ziAndy Wingo2022-01-131-4/+16
| | | | | * libguile/integers.c (scm_integer_sub_zi): Only delegate to scm_integer_add_ii if y is negative.
* Optimize scm_integer_mul_zz.Andy Wingo2022-01-131-6/+18
| | | | | * libguile/integers.c (scm_integer_mul_zz): Optimize to avoid temporary allocations.
* Optimize scm_integer_mul_ziAndy Wingo2022-01-131-5/+25
| | | | | | * libguile/integers.c (bignum_trim1): (bignum_negate_if): New helpers. (scm_integer_mul_zi): Use the mpn API to avoid temporary allocation.
* Re-rewrite integer-expt in CAndy Wingo2022-01-133-13/+134
| | | | | | | | | | | Calling out to Scheme was a performance regression. * libguile/integers.h: * libguile/integers.c (scm_integer_expt_ii, scm_integer_expt_zi): New internal functions. * libguile/numbers.c (scm_integer_expt): Go back to C. But, include fast cases for inums and doubles. * module/ice-9/boot-9.scm: Revert addition of integer-expt.
* Fix bug when making mpz from 0Andy Wingo2022-01-131-3/+9
| | | | | | | * libguile/integers.c (make_bignum_0): New helper. (make_bignum_from_uint64): (ulong_to_bignum): (long_to_bignum): Call new helper as appropriate.
* take_mpz optimizationAndy Wingo2022-01-131-2/+6

* Bignums avoid both custom GMP allocator and finalizersAndy Wingo2022-01-134-183/+111
| | | | | | | | | | | | | | | | | | | | | * libguile/deprecated.c (make_bignum): Move here from numbers.c, to support scm_i_long2big etc. (scm_i_big2dbl): (scm_i_long2big): (scm_i_ulong2big): (scm_i_clonebig): (scm_i_normbig): Deprecate. (scm_install_gmp_memory_functions): Deprecate, happily! SCM bignums now have digits allocated inline with the bignum itself, so they are completely transparent to the GC already. The price is that if GMP ever allocates digits via the MPZ API, those digits then have to be copied back into managed memory. But we avoid having to install finalizers and we avoid having to muck with GMP's allocator. * libguile/numbers.c (scm_from_mpz): Use scm_integer_from_mpz. (scm_init_numbers): Never muck with GMP's allocators. * doc/ref/guile-invoke.texi (Environment Variables): Remove note about GUILE_INSTALL_GMP_MEMORY_FUNCTIONS. * meta/build-env.in: No need to set GUILE_INSTALL_GMP_MEMORY_FUNCTIONS.
* scm_to_ipv6 uses scm_to_mpzAndy Wingo2022-01-131-5/+11
| | | | * libguile/socket.c (scm_to_ipv6): Use scm_to_mpz.
