* libguile/symbols.c (intern_symbol): New function, with code formerly
duplicated in `scm_i_c_mem2symbol ()' and `scm_i_mem2symbol ()'.
(scm_i_c_mem2symbol, scm_i_mem2symbol): Use it.
(scm_take_locale_symboln): Use `intern_symbol ()'. This fixes
bug #25865.
* test-suite/standalone/Makefile.am
(test_scm_take_locale_symbol_SOURCES,
test_scm_take_locale_symbol_CFLAGS,
test_scm_take_locale_symbol_LDADD): New variables.
(check_PROGRAMS, TESTS): Add `test-scm-take-locale-symbol'.
(Reported by Panicz Maciej Godek.)
* test-suite/tests/syncase.test ("@ works with syncase"): New test.
* ice-9/syncase.scm (guile-macro): When a Guile macro transformer
produces a variable, don't pass it through sc-expand.
Reported by Roland Haeder. The declaration and definition of
scm_pthread_cond_timedwait were using possibly different types for the
third arg.
* THANKS: Added Roland Haeder.
* libguile/threads.h (scm_pthread_cond_timedwait): Use scm_t_timespec
for third arg rather than struct timespec, for consistency with the
function implementation.
* libguile/strings.c (scm_string_ref): Add proper range checking for the
empty string.
(scm_string_set_x): Likewise.
Reported by Bill Schottstaedt <bil@ccrma.Stanford.EDU>.
* test-suite/tests/strings.test ("string-ref"): New test prefix.
("string-set!")["empty string", "empty string and non-zero index",
"out of range", "negative index", "regular string"]: New tests.
* NEWS: Update.
* NEWS: Update.
* libguile/threads.c (scm_i_init_thread_for_guile): When the thread is
already guilified, update `t->base' so that it corresponds to the new
stack base. Bug report and patch by Linas Vepstas <linasvepstas@gmail.com>.
* test-suite/standalone/Makefile.am (test_scm_with_guile_CFLAGS,
test_scm_with_guile_LDADD): New.
(check_PROGRAMS, TESTS): Add `test-scm-with-guile'.
For explanation, see comments and text in the new file
libguile/measure-hwm.scm.
* .gitignore: Add libguile/stack-limit-calibration.scm.
* check-guile.in: Load libguile/stack-limit-calibration.scm.
* configure.in: Add AC_CONFIG_FILES to generate test-use-srfi from
test-use-srfi.in.
* libguile/Makefile.am (TESTS, TESTS_ENVIRONMENT,
stack-limit-calibration.scm): New targets, so that `make check'
calibrates the stack limit before running the Guile test suite.
* libguile/measure-hwm.scm: New file, calibrates stack limit for `make
check'.
* libguile/stackchk.c (scm_sys_get_stack_size): New primitive.
* libguile/stackchk.h (scm_sys_get_stack_size): New primitive
(declaration).
* test-suite/standalone/test-use-srfi: Renamed test-use-srfi.in, so
that ./configure can fill in variables in it.
* test-suite/standalone/test-use-srfi.in: Load
libguile/stack-limit-calibration.scm.
* libguile/threads.c (scm_threads_mark_stacks): Cast `&t->regs' to
`(void *)' rather than `(SCM_STACKITEM *)' to avoid "warning:
dereferencing type-punned pointer will break strict-aliasing rules"
with GCC 4.2.1 on `i386-unknown-freebsd7.0'.
* ice-9/regex.scm (fold-matches): If FLAGS is non-null, use
`(car flags)', not `flags'.
* test-suite/tests/regexp.test ("fold-matches"): New test prefix.
* NEWS: Update.
* libguile/read.c (scm_read_string): Use `scm_i_make_read_only_string ()' to
return a read-only string, as mandated by R5RS. Reported by Bill
Schottstaedt <bil@ccrma.Stanford.EDU>.
* libguile/strings.c (scm_i_make_read_only_string): New function.
(scm_i_shared_substring_read_only): Special-case the empty string
so that the read-only and read-write empty strings are `eq?'. This
optimization is relied on by the `substring/shared' `empty string'
test case in `srfi-13.test'.
* libguile/strings.h (scm_i_make_read_only_string): New declaration.
* test-suite/tests/strings.test ("string-set!")["literal string"]: New test.
* NEWS: Update.
* libguile/strings.c (scm_i_symbol_substring): Return a read-only string
since R5RS requires `symbol->string' to return a read-only string.
Reported by Bill Schottstaedt <bil@ccrma.Stanford.EDU>.
* test-suite/tests/symbols.test: Add `define-module' clause.
(exception:immutable-string): Adjust to current exception.
("symbol->string")["result is an immutable string"]: Use
`pass-if-exception' instead of `expect-fail-exception'.
* NEWS: Update.
(reported by Bill Schottstaedt)
* libguile/numbers.c (scm_gcd): When only one arg given, use scm_abs
to ensure that result is non-negative.
* test-suite/tests/numbers.test ("gcd"): New test, (gcd -2).
When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.
* scheme-using.texi (Evaluating Scheme Code): Document use of
`C-u' prefix with evaluation commands.
* gds-scheme.el (gds-eval-region, gds-eval-expression)
(gds-eval-defun, gds-eval-last-sexp): Support `C-u' prefix,
meaning that user wants to single step through the code.
* gds-client.scm (handle-nondebug-protocol): Add support for
setting a trap on code that is about to be evaluated.
* configure.in: Update stack direction test to be like that in
Autoconf _AC_LIBOBJ_ALLOCA and Gnulib; specifically in involving a
function calling itself.
