This is a regression since Guile 3.0.2 and breaks compilation
of a Guile library.
* module/ice-9/read.scm
(%read)[read-parenthesized]: When SAW-BRACE? is #t but CH isn't
#\#, don't eat CH.
* test-suite/tests/reader.test
("#{}#): Add four test cases.
In 3.0.7 (after 0cc7991855 "Ensure
that (syntax ()) results in ("), the use of #nil in syntax-rules
expansions like this:
(define-syntax foo
(syntax-rules ()
((_ x) (eq? #nil x))))
(foo #t)
could cause a crash that looks like this:
ice-9/psyntax.scm:2795:12: In procedure syntax-violation:
Syntax error:
unknown location: unexpected syntax in form ()
To fix it, add another special case (the commit mentioned above
special-cased the empty list) to preserve #nil
* module/ice-9/psyntax.scm (gen-syntax): Preserve #nil.
* test-suite/tests/syntax.test: Test #nil in syntax expansions.
Closes: 49305
* module/language/cps/cse.scm (compute-out-edges): Only propagate
constant to successor if successor not kf.
* test-suite/tests/compiler.test ("cse auxiliary definitions"):
("closure conversion"): Refactor.
("constant propagation"): New test.
Fixes#48368.
In the part about lambda formals, change "arguments will converted into"
to "arguments will BE converted into".
* doc/ref/api-procedures.texi (Lambda: Basic Procedure Creation):
Fix typo.
* guile-readline/readline.c (scm_filename_completion_function):
A completion function should return #f when there's no more
candidates. Since the result of readline's
rl_filename_completion_function was never checked it was impossible
for it to work as intended and instead of #f it threw an error from
trying to convert NULL to an scm string.
* am/bootstrap.am (SOURCES):
* module/Makefile.am (SOURCES):
* module/language/tree-il/optimize.scm (make-optimizer): Wire up the new
pass.
* module/language/tree-il/resolve-free-vars.scm: New pass.
* module/system/base/optimize.scm (available-optimizations): Enable new
pass at -O1.
* module/language/tree-il/letrectify.scm (letrectify): Inline "let"
bindings inside residualized "letrec*" forms, to allow the dominator
relationship to be reflected in the scope tree. Also, detect
"define-module*" invocations, and add these to the mod-vars set, so that
residualized "module-ensure-local-variable!" primcalls can clearly
denote their module without having to use "current-module".
This enables the compilation from "manually" written Tree-IL to
bytecode. See also <https://bugs.gnu.org/45131>.
* system/base/compile.scm (read-and-compile)[(joint #f)]<? eof-object?>:
Join exps using the default joiner for to.
<exp>: Compute compiler for to.
* test-suite/test/compiler.test ("read-and-compile tree-il"): New test.
Partly fixes <https://bugs.gnu.org/41948>.
Previously, the child process could end up using the same 'sleep_pipe'
as its parent, leading to a race condition handling signals.
* libguile/posix.c (do_fork): New function.
(scm_fork): Call 'do_fork' via 'scm_without_guile'.
* test-suite/standalone/test-signal-fork: New test.
* test-suite/standalone/Makefile.am (check_SCRIPTS, TESTS): Add it.
Partly fixes <https://bugs.gnu.org/41948>.
Reported by Mathieu Othacehe <othacehe@gnu.org>.
Previously, after 'fork', the child process could end up sharing the
finalization thread with its parent.
* libguile/finalizers.c (finalization_pipe): Initialize.
(reset_finalization_pipe): Factored out.
(start_finalization_thread): Create the pipe immediately before
launching the thread. Ensure the pipe is cleaned up if thread creation
fails. Update the finalizer callback if thread creation succeeds.
(stop_finalization_thread): Clean up the pipe after stopping the thread.
(spawn_finalizer_thread): Remove finalizer callback logic.
(scm_set_automatic_finalization_enabled): Remove pipe management.
(scm_init_finalizer_thread): Remove pipe management.
Co-authored-by: Ludovic Courtès <ludo@gnu.org>
* testing.scm (%test-begin, %test-end): When (test-runner-current) is
not set, create a new one like before but also add a finalizer that
will remove it after the test is finished. Previously the test runner
was getting unset unconditionally.

Fixes <https://bugs.gnu.org/47031>.
* module/language/tree-il/analyze.scm (make-use-before-definition-analysis)
[resolve]: Add case for when NAME is re-exported by MOD.
* test-suite/tests/tree-il.test ("warnings")["re-exported binding"]: New test.
* libguile/mini-gmp.c: Add config.h include. Handles the case in which
gnulib provides some part of the standard library of mini-gmp, as is
apparently the case on FreeBSD for example. Thanks to RhodiumToad for
the report and fix.
* module/ice-9/r7rs-libraries.scm (define-library): Fix bug handling
include-library-declarations and cond-expand subforms. Thanks to Adam
Nelson for the fix! Fixes#40252.
* module/language/tree-il/effects.scm (make-effects-analyzer): The body
of a prompt is an expression only for escape-only prompts, and the
handler is always a lambda. Fix bug where a prompt could be incorrectly
marked effect-free.
* test-suite/tests/tree-il.test ("optimize"): Add test for bug 48098.
Fixes bug 48098.
* module/ice-9/psyntax.scm (syntax-violation): Pass source as an alist.
A sourcev would be better but it's incompatible.
* module/ice-9/psyntax-pp.scm: Regenerate.
Hi!
In 3.0.6, a slight incompatibility crept in: ‘syntax-error’ exceptions
include vectors like #("example.scm" 1 2) instead of good’ol source
property alists.
Here is a test case that reproduces the problem:
* module/ice-9/read.scm (%read): Add 1 to both line and column: the
former to make 1-based user lines instead of 0-based Guile lines, and
the latter because apparently that's how we always did it :) Fixes
Ludovic Courtès <ludo@gnu.org> skribis:
> Guile 3.0.6 returns zero-indexed (instead of one-indexed) source code

Here’s a test case waiting to succeed! :-)
* module/ice-9/boot-9.scm (duplicate-handlers): Use module-variable
instead of module-local-variable in the warn-override-core, first, and
last handlers. Fixes#47084 mostly, though relative to pre-3.0 there is
still a difference in that a module needs to explicitly declare which
bindings are intended as replacements -- a binding being a replacement
is a property of the module in 3.0, rather than the variable as was the
case before 3.0.
* module/language/cps/closure-conversion.scm (convert-one): Fix bug when
getting value of SCC whose free variables have been elided. Thanks to
abcdw for the report!
* test-suite/tests/compiler.test ("cse auxiliary definitions"): Remove
spurious newline.
("closure conversion"): New test.
