* libguile/boolean.c (scm_nil_p): New function.
* libguile/vm-i-scheme.c (nilp, not_nilp):
* libguile/vm-i-system.c (br_if_nil, br_if_not_nil): New instructions.
Renumber other ops.
* libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Increment.
* module/language/assembly/compile-bytecode.scm (compile-bytecode): Add
support for writing `br-if-nil' and `br-if-not-nil' instructions.
* module/language/assembly/disassemble.scm (code-annotation): Add
`br-if-nil' and `br-if-not-nil' to the list of branch instructions.
* module/language/tree-il/compile-glil.scm: Add `nil?' to
`*primcall-ops*'.
(flatten): Use the new branch instructions for `nil?' conditionals.
* module/language/tree-il/primitives.scm: Add `nil?' to
`*interesting-primitive-names*', `*effect-free-primitives', and
`*effect+exception-free-primitives*'.
* libguile/control.c:
* libguile/continuations.c: Fix for the case in which SCM_ALIGNED is not
defined. Though I wonder, perhaps we should just error out in those
cases.
* configure.ac: Remove checks for <langinfo.h> and <nl_types.h>, and
`nl_langinfo'.
* libguile/i18n.c: Remove #ifdefs for HAVE_LANGINFO_H, HAVE_NL_TYPES_H,
HAVE_NL_ITEM, and HAVE_LANGINFO_CODESET.
(SCM_VALIDATE_OPTIONAL_LOCALE_COPY): Use `SCM_UNBNDP'.
* m4/gnulib-cache.m4 (gl_MODULES): Add `nl_langinfo'.
* module/ice-9/i18n.scm (define-vector-langinfo-mapping): Remove
`defaults' parameter; assume (provided? 'nl-langinfo) is always true.
Update users accordingly.
(define-simple-langinfo-mapping): Likewise.
(define-monetary-langinfo-mapping): Likewise, but do not assume
LOCAL-ITEM and INTL-ITEM are always defined.
This should help with regex portability, as reported in
<http://bugs.gnu.org/10684> for Darwin 8.11.
* m4/gnulib-cache.m4 (gl_MODULES): Add `regex'.
* configure.ac: Remove header checks for regex.h, rxposix.h, and
rx/rxposix.h. Remove check for the `regcomp' function. Remove
definition of `HAVE_REGCOMP'. Define `ENABLE_REGEX'.
* libguile/init.c: Check for `ENABLE_REGEX' instead of `HAVE_REGCOMP'.
* libguile/regex-posix.c: Always include <regex.h>. Remove #ifdefs for
rxposix.h and co.
* doc/ref/posix.texi (Network Databases): Update description of
`EAI_NODATA' to mention that Darwin provides it.
* libguile/net_db.c (scm_getaddrinfo): Likewise.
* test-suite/tests/net-db.test ("getaddrinfo")["wrong service name"]:
Accept `EAI_NODATA' too. Reported by David Fang <fang@csl.cornell.edu>,
see <http://bugs.gnu.org/10684>.
* libguile/load.c (search_path): When the provided 'filename' is an
absolute pathname, perform a 'stat' on that pathname to fill the
'stat_buf'. Previously, 'stat_buf' was left uninitialized in this
case, even though 'scm_primitive_load_path' assumes that 'stat_buf'
will be filled. Update the header comment to explicitly specify that
'stat_buf' will be filled. Also 'goto end' in a few failure cases
instead of replicating its code.
* libguile/foreign.h: Remove comment about the finalizer bit, as I don't
think that is the case any more.
* test-suite/tests/gc.test: Ignore flakiness in the gc-modules test.
* libguile/i18n.c (scm_make_locale): Null out c_locale_name after it's
freed, so it doesn't get freed again. While this only has effect if
USE_GNU_LOCALE_API is unset, the nulling out happens in both cases,
to be consistent and robust.
(scm_nl_langinfo): Free c_result in all switch cases, in particular
P_SIGN_POSN, N_SIGN_POSN, INT_P_SIGN_POSN, and INT_N_SIGN_POSN.
* libguile/vm-engine.h (DEAD): New macro, nulls out a value.
* libguile/vm-i-system.c:
* libguile/vm-i-loader.c:
* libguile/vm-i-scheme.c: Use DEAD when variables become dead.
Later we can #ifdef this out, but I want to give the buildbots a try
with this patch to make sure it's correct.
* libguile/macros.c (scm_init_macros): Add definition of new
syntax-session-id helper.
* module/ice-9/psyntax.scm: Capture a reference to syntax-session-id at
boot time. Uniquify marks and labels using the session id.
* module/ice-9/boot-9.scm: Shunt syntax-session-id off to (system
syntax) once we finished booting.
* module/ice-9/compile-psyntax.scm: Override syntax-session-id when
remaking psyntax to avoid spurious diffs.
* module/ice-9/psyntax-pp.scm: Regenerate.
This reverts commit ad432bc831.
Not all gensyms need to be universally-unique: most of them just need to
be unique within some portion of a Guile session. We'll take a
different tack on this problem in the next commit.
* module/ice-9/local-eval.scm: New module (ice-9 local-eval) which
exports `the-environment', `local-eval', and `local-compile'.
* libguile/debug.c (scm_local_eval): New C function that calls the
Scheme implementation of `local-eval' in (ice-9 local-eval).
* libguile/debug.h (scm_local_eval): Add prototype.
* doc/ref/api-evaluation.texi (Local Evaluation): Add documentation.
* test-suite/tests/eval.test (local evaluation): Add tests.
* test-suite/standalone/test-loose-ends.c (test_scm_local_eval):
Add test.
* module/Makefile.am: Add ice-9/local-eval.scm.
Based on a patch by Mark H Weaver <mhw@netris.org>.
Fixes part of <http://bugs.gnu.org/10520>.
Reported by Bruno Haible <bruno@clisp.org>.
* libguile/vm-i-system.c (COMPILER_BARRIER): New macro.
(halt, return, return_values): Insert compiler barrier after each
assignment to `fp'.
This is a followup to 690a0112e5 ("Remove
the "has finalizer?" bit from pointer objects.")
* libguile/foreign.c (scm_set_pointer_finalizer_x): Leave the type cell
unchanged. Before, `equal?' would break on pointers on which
`set-pointer-finalizer!' had been called.
* test-suite/tests/foreign.test ("make-pointer")["equal? modulo
finalizer (set-pointer-finalizer!)"]: New test.
* libguile/hashtab.c (scm_i_hashtable_print): Use `SCM_UNPACK', not
`SCM2PTR'.
* test-suite/tests/hash.test: Adjust tests that rely on the output of
the printer to just check for the suffix of the hash table's external
representation.
* libguile/frames.c: Add compile-time assertions on the layout of
`struct scm_vm_frame'.
(RELOC): Parenthesize and type VAL.
* libguile/frames.h (SCM_FRAME_STRUCT): Write in terms of
`SCM_FRAME_DATA_ADDRESS'.
(SCM_FRAME_DATA_ADDRESS): Parenthesize and type FP.
(SCM_FRAME_SET_DYNAMIC_LINK): Write in terms of
`SCM_FRAME_DYNAMIC_LINK'.
* libguile/vm.c (RELOC): Parenthesize and type SCM_P.
* libguile/symbols.c (scm_gensym): Make the gensym counter a 128-bit
thread-local, initialized to a random number upon the first call to
`gensym' within a given thread. This counter is rendered as a 22 byte
suffix of mostly base64 digits.
* libguile/threads.h (scm_i_thread): Add a thread-local gensym_counter.
* libguile/threads.c (guilify_self_1): Initialize gensym_counter to NULL.
Based on a patch by Julian Graham <julian@member.fsf.org>
* libguile/values.c, libguile/values.h (scm_c_value_ref): New function.
* doc/ref/api-control.texi (Multiple Values): Add documentation.
* test-suite/standalone/test-scm-values.c: New test program.
* test-suite/standalone/Makefile.am: Add test-scm-values test.
* m4/gnulib-cache.m4: Use `dirfd'.
* libguile/filesys.c: Include Gnulib's <dirent.h> directly.
(dirfd): Remove. Suggested by Bruno Haible <bruno@clisp.org>.
* libguile/strings.c (scm_i_substring, scm_i_substring_read_only,
scm_i_substring_shared): When asked to create an empty substring,
return a freshly allocated null string. Previously, an empty
substring needlessly held a reference to the original stringbuf.
* libguile/strings.c (scm_from_stringn): Avoid calling
`u32_conv_from_encoding' on the null string, by using the same
fast-path code used if (encoding == NULL). This is an optimization,
and also avoids any possible encoding errors.
* libguile/strings.c (scm_from_stringn): Always return a freshly
allocated string from scm_from_stringn, even when asked to construct
the null string, in accordance with the R5RS. Previously, we
optimized the null string case by returning a reference to a global
null string object (scm_nullstr).
