* 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.
* 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).
* test-suite/standalone/Makefile.am (test_cflags): Add `-I$(top_builddir)' so
that <config.h> can be found.
(snarfcppopts): Likewise.
* test-suite/standalone/*.c: Include <config.h>.
(scm_current_module): Return the root module if `the-module' fluid
gives #f.
* standalone/Makefile.am: Add stanza for test-with-guile-module.
* standalone/test-with-guile-module.c: New test.
returns neither a pair nor #f, signal a wrong-type-arg error.
(Thanks to Gregory Marton for reporting this.)
* tests/hash.test: New "hashx" test supplied by Gregory Marton;
prior to today's fix in libguile/hashtab.c, this caused a
segmentation fault.
* tests/continuations.test ("continuations"): Use
with-debugging-evaluator.
* standalone/test-use-srfi: Use -q to avoid picking up the user's
~/.guile file
* lib.scm (with-debugging-evaluator*, with-debugging-evaluator):
New utilities.
