Thanks to Greg Troxel for reporting, and Barry Fishman for the
explanation and fix.
* test-suite/tests/popen.test ("open-input-pipe"): Use shell function
`read' with an explicit argument, as apparently not all shells
support read with no argument.
* libguile/threads.c (scm_join_thread): Always recheck t->exited
before calling block_self again, in case thread t has now exited.
* test-suite/tests/threads.test (joining): New test.
On the one hand we want the child process in these tests to exit. On
the other, we don't want it to exit before the parent Guile code has
tested the relevant condition (EOF in the first test, broken pipe in
the second) - because these conditions would obviously be true if the
child had already exited, and that's not what we're trying to test
here. We're trying to test getting EOF and broken pipe while the
child process is still alive.
* test-suite/tests/popen.test (open-input-pipe:no duplicate): Add
another pipe from parent to child, so that the child can finish by
reading from this. Then the parent controls the child lifetime by
writing to this pipe.
* test-suite/tests/popen.test (open-output-pipe:no duplicate): Add
another pipe from child to parent, and have the child finish by
endlessly writing into this. Then the parent controls the child
lifetime by closing its end of the pipe, causing a broken pipe in
the child.
* test-suite/tests/reader.test ("read-options"): Add test
for long postfix keywords.
* libguile/read.c (scm_read_mixed_case_symbol): Fix
exception on symbols are greater than 128 chars. Also,
colons are not stripped from long postfix keywords.
(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.
* 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.
* 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).
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.
