Commit c46fee438c removed the "bdw-gc.h"
include from "smob.h", so better avoid `GC_PTR'.
* libguile/smob.c (scm_i_finalize_smob): Use `void *' instead of `GC_PTR'.
* libguile/smob.h (scm_i_finalize_smob): Update declaration accordingly.
Fixed <http://bugs.gnu.org/11196>.
Reported by Klaus Stehle <klaus.stehle@uni-tuebingen.de>.
* module/srfi/srfi-9.scm (define-record-type): Define the contructor
before TYPE-NAME. Set RTD's constructor field.
* test-suite/tests/srfi-9.test ("record compatibility"): New test
prefix.
* libguile/strings.c (scm_to_utf8_stringn): Fix another new bug in this
recent comedy of errors: pass the size of the preallocated buffer to
u32_to_u8. Arrange to call 'scm_i_string_wide_chars' and
'scm_i_string_length' only once each. Rename local variables for
improved code clarity.
* test-suite/standalone/test-conversion.c (test_to_utf8_stringn): New
function to test scm_to_utf8_stringn.
* libguile/strings.c (u32_u8_length_in_bytes): Internal static function
renamed from u32_u8_strlen, whose name was potentially confusing. For
added safety, handle everything that can be encoded in the more
general UTF-8 encoding: up to six bytes for each code point, with code
points up to 2^31-1.
(scm_to_utf8_stringn): NUL-terminate only if (lenp == NULL).
If (lenp != NULL) return the length in bytes in *lenp.
* module/language/tree-il/primitives.scm (resolve-primitives!): Resolve
public module-refs to primitives.
* test-suite/tests/tree-il.test: New tests for primitive resolution.
* libguile/srfi-13.c (scm_string_trim, scm_string_trim_right)
(scm_string_trim_both): Take the whitespace fast-path if the char_pred
is scm_char_set_whitespace.
* module/web/http.scm (read-header, split-and-trim, parse-quality-list):
(parse-param-component, parse-credentials, "Content-Type"):
(read-request-line, read-response-line): Use char-set:whitespace
instead of char-whitespace?. It avoids recursing into the VM.
* libguile/vm.c (prepare_smob_call): New helper. Now, instead of making
a per-smob trampoline, we will shuffle the smob into the args and use
a gsubr. This prevents a memory leak in which the trampolines, which
were values in a weak-key table, were preventing the smobs from being
collected.
* libguile/vm-i-system.c (call, tail-call, mv-call): Adapt to new smob
application mechanism.
(smob-call): Remove this instruction.
* libguile/smob.h (scm_smob_descriptor): Rename apply_trampoline_objcode
to apply_trampoline.
* libguile/smob.c: Remove our own objcode trampolines in favor of using
scm_c_make_gsubr.
(scm_smob_prehistory): No more trampoline weak map.
* libguile/procprop.c (scm_i_procedure_arity): Adapt to applicable smob
representation change.
* module/web/server/http.scm (bad-request, http-read): If an exception
is raised while reading a response, write out a 400 Bad Request
response before closing the port.
* libguile/finalizers.c: New excitement! We'll be running finalizers
asynchronously, from asyncs. This will make it safer to allocate
while holding a mutex.
(GC_set_finalizer_notifier): Add back-compat shim.
* libguile/init.c (scm_i_init_guile): Init the async finalizer mechanism
during boot.
* libguile/gc.c (scm_storage_prehistory): Tell libgc we'll be finalizing
on demand.
(scm_gc): Explicitly run finalizers here.
* libguile/threads.c (guilify_self_2): Run finalizers here if
queue_finalizer_async happened to run during guilify_self_1.
* configure.ac: Add check for GC_set_finalizer_notifier.
* libguile/smob.h (scm_new_smob, scm_new_double_smob): New constructors,
which do what SCM_NEWSMOB / SCM_NEWSMOB3 had done, but with inline
functions instead of macros. They also bail to scm_i_new_smob /
scm_i_new_double_smob in either the mark or the free case, so that the
inline definition doesn't reference other internal details like libgc
stuff.
(SCM_SMOB_TYPE_MASK et al): Move definitions up so the new_smob see
them as already being declared.
(SCM_NEWSMOB, SCM_RETURN_NEWSMOB, SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2):
(SCM_NEWSMOB3, SCM_RETURN_NEWSMOB3): Reimplement in terms of the new
inline functions.
Remove now-unneeded bdw-gc include.
* libguile/smob.c (finalize_smob): Rename from scm_i_finalize_smob, and
make static.
(scm_i_new_smob, scm_i_new_double_smob): Slow-path allocators.
(scm_i_finalize_smob, scm_i_new_smob_with_mark_proc): Add
back-compatibility shims to preserve ABI.
* libguile/inline.c: Include smob.h, so as to reify scm_new_smob and
scm_new_double_smob.
* libguile/inline.h:
* libguile/gc.h (scm_cell, scm_double_cell, scm_words): Move
declarations and definitions back here, from inline.h. It's more
natural.
* libguile/inline.c: Include gc.h as well.
* libguile/__scm.h (SCM_C_EXTERN_INLINE): Move this definition here,
from inline.h. We'd like to support inline function definitions in
more header files: not just inline.h.
(SCM_CAN_INLINE, SCM_INLINE, SCM_INLINE_IMPLEMENTATION): New
definitions.
* libguile/gc.h (SCM_GC_MALLOC, SCM_GC_MALLOC_POINTERLESS): Define these
wrappers, which redirect to the GC_MALLOC macros when building Guile,
and the scm_gc_malloc functions otherwise. A step towards getting
BDW-GC out of Guile's API.
* libguile/inline.h: Simplify, using SCM_INLINE,
SCM_INLINE_IMPLEMENTATION, and SCM_IMPLEMENT_INLINES. Also use the
new SCM_GC_MALLOC macros.
* benchmark-suite/benchmarks/ports.bm (sequence): New macro, formerly
local to the "rdelim" benchmark prefix.
(large-string): New procedure.
(%latin1-port, %utf8/ascii-port, %utf8/wide-port): Use it.
("peek-char", "char-ready?", "read-char"): Use `sequence'.
* doc/ref/api-data.texi (String Comparison): Remove documentation for
scm_i_string{,_ci}_{equal,less,leq,gr,geq}_p, which are not only
internal functions but static, and thus unusable by external code.
* module/ice-9/psyntax.scm (do, case): Comment out these definitions,
which are never used and immediately replaced by definitions in
boot-9.scm.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (subst-rename?, rename-old, rename-new,
rename-marks, make-rename): Remove these unused syntax rules.
Fix description of syntax wraps to match current reality.
* module/ice-9/compile-psyntax.scm: Minimize syntax object literals
embedded in psyntax-pp.scm.
* module/ice-9/psyntax.scm: Rename a few variables so that syntax
objects embedded in macros have no lexical bindings, so that their
minimized syntax objects will have no embedded labels. These labels
were the last remaining gensym counters in psyntax-pp.scm.
* module/ice-9/psyntax-pp.scm: Regenerate. It is now less than one
quarter of its previous size! More importantly, this file no longer
contains any gensym counters, which means that in the future, local
changes to psyntax.scm will usually result in only local changes to
psyntax-pp.scm.
* module/language/tree-il.scm (tree-il->scheme): New implementation that
simply calls 'decompile-tree-il'.
* module/language/scheme/decompile-tree-il.scm (choose-output-names,
do-decompile): New internal procedures.
(decompile-tree-il): New and improved implementation. Print source
identifiers where possible, otherwise add minimal numeric suffixes.
Previously we printed the gensyms. Avoid 'begin' in contexts that
provide an implicit 'begin'. Produce 'cond', 'case', 'and', 'or',
'let*', named let, and internal defines where appropriate. Recognize
keyword arguments in 'opts' to disable the production of these derived
syntactic forms, and to optionally strip numeric suffixes from
variable names.
* module/ice-9/compile-psyntax.scm: Disable partial evaluation, letrec
fixing, and primitive expansion when producing psyntax-pp.scm, in
order to produce output as close to the original source as practical.
Disable production of derived syntactic forms as needed during
bootstrap. Strip numeric suffixes from variable names. Adjust
pretty-printing parameters.
* module/ice-9/psyntax-pp.scm: Regenerate. It is now less than half
of the original size.
* module/ice-9/pretty-print.scm (pretty-print): Add new keyword argument
'#:max-expr-width'.
(generic-write): Add new argument 'max-expr-width'. Previously this
was internally defined to the constant value 50.
* module/language/tree-il/analyze.scm (proc-ref?): Change to use less
false-if-exception and more variable-bound?. If a variable is present
in the local module but not bound, assume that it is gettext if it has
the right name. This is to allow for (define _ gettext).
* test-suite/tests/tree-il.test ("warnings"): Update (_ "foo") example.
* module/language/tree-il/peval.scm (peval): Add optimization to
hoist the inner procedure out of e.g.
(lambda args (apply (lambda ...) args))
This commit restores the ability to detect escape-only prompts at
compile-time.
* test-suite/tests/tree-il.test: Update test for prompt with a lambda,
and add a specific test for lambda application.
* module/language/tree-il/canonicalize.scm (canonicalize!): Fix a bug in
which the sense of `escape-only?' was reversed. We never saw this
though, because for other reasons, no prompts were being identified as
escape-only.
* module/language/tree-il/primitives.scm (*primitive-expand-table*):
Don't limit the call-with-prompt to <prompt> transition to lambda
expressions. Instead we can lexically bind the handler, and rely on
peval to propagate a lambda expression.
* module/system/base/pmatch.scm (pmatch): Always wrap with 'let', even
if the expression appears atomic, because in the presence of
'identifier-syntax', we cannot know what an atomic expression will
later expand to. Also use '#:export-syntax' instead of '#:export'
to export 'pmatch'.
* module/srfi/srfi-4.scm, module/srfi/srfi-4/gnu.scm
(define-bytevector-type): Fix definition of <TAG>vector-length when
applied to uniform vectors of different element sizes. Thanks to
Tobias Brandt <tob.brandt@googlemail.com> for reporting this bug.
* test-suite/tests/srfi-4.test: Add tests.
* module/language/tree-il/analyze.scm (proc-ref?): Wrap `variable-ref'
in `false-if-exception'.
* test-suite/tests/tree-il.test ("warnings")["format"]("non-literal
format string with forward declaration"): New test.
* test-suite/tests/srfi-18.test: Enclose the tests in a begin instead of
an and. Before, they were not being run, for some reason I don't
fully understand.
* 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.
* module/language/tree-il/analyze.scm (gettext?): Rename to...
(proc-ref?): ... this. Add `proc' and `special-name' parameters.
(gettext?): Define in terms of `proc-ref?'.
(ngettext?): New procedure.
(const-fmt): Recognize `ngettext' calls.
(format-analysis)[<down>](check-format-args]: Check
constant-but-non-string 2nd argument in the (not (const-fmt ...))
case.
[check-simple-format-args]: Use `const-fmt'.
* test-suite/tests/tree-il.test ("warnings")["format"]("non-literal
format string using ngettext", "non-literal format string using
ngettext as N_"): New tests.
("simple-format")["unsupported, ngettext"]: New test.
Fixes <http://bugs.gnu.org/10846>.
Reported by Bruno Haible <bruno@clisp.org>.
* module/language/tree-il/analyze.scm (gettext?): New procedure.
(const-fmt): Add `env' parameter; update callers. Use `gettext?'.
(format-analysis)[check-simple-format-args]: Actually support
gettextized format strings.
* test-suite/tests/tree-il.test ("warnings")["format"]("non-literal
format string using gettext"): Use `gettext' as the procedure name.
("non-literal format string using gettext as _"): New test.
["simple-format"]("unsupported, gettext"): New test.
