* libguile/control.h:
* libguile/control.c (scm_i_prompt_pop_abort_args_x): Take a VM instead
of a prompt, given that it's the VM's registers that record the abort
arguments, not the prompt registers (which actually point right below
the abort values).
* libguile/eval.c (eval):
* libguile/throw.c (pre_init_catch): Pass the vm instead of a prompt.
* configure.ac: Check for GC_pthread_exit and GC_pthread_cancel.
* libguile/gen-scmconfig.c: Write HAVE_GC_PTHREAD_CANCEL and
HAVE_GC_PTHREAD_EXIT into scmconfig.h.
* libguile/pthread-threads.h (scm_i_pthread_exit, scm_i_pthread_cancel):
Only redefine to their GC_pthread_* variants if we have those
functions, which is not the case in libgc < 7.2.
* module/language/objcode/spec.scm (decompile-value): Don't assume that
`error' will handle format strings appropriately.
* module/system/repl/command.scm (disassemble): A more human error when
you disassemble a non-procedure.
Bug reported by Andrew Horton.
* doc/ref/scheme-scripts.texi (Invoking Guile): Document -q.
* doc/ref/scheme-using.texi (Init File): New section, on .guile.
(Readline): Link to Init File.
(System Commands): Document the various REPL options, and
repl-default-option-set!.
* module/language/tree-il/compile-glil.scm (flatten): When compiling a
<prompt> in push context with an RA, after the body returns normally,
jump to that RA instead of to our POST label (which in that case does
not need to be emitted). Fixes a tail <prompt> in a push <fix>.
* test-suite/tests/control.test ("prompt in different contexts"): Add
more test cases.
* doc/ref/tools.texi (Executable Modules): Say "guile-tools modules"
instead of "executable modules". Remove obsolete statements about
not ending in .scm, being executable, and beginning with shell
script invocation sequence.
* module/scripts/README: Ditto.
It's just one variable definition, and in my opinion it confuses,
rather than helps, the overall build picture to have two names
(preinstguile and meta/guile) for the same thing.
* am/Makefile.am (am_frags): Remove pre-inst-guile.
* am/pre-inst-guile: Deleted.
* doc/ref/Makefile.am: Don't include am/pre-inst-guile.
($(snarf_doc).am, $(snarf_doc).texi): Expand $(preinstguile).
* module/Makefile.am (ice-9/psyntax-pp.scm.gen): Don't include
am/pre-inst-guile.
(ice-9/psyntax-pp.scm.gen): Expand $(preinstguile).
* libguile/threads.c (guilify_self_1): Prevent finalizers from running
before SCM_I_CURRENT_THREAD is set.
(do_thread_exit_trampoline): Leave the thread in the registered state.
(on_thread_exit): Always unregister the thread here.
* libguile/init.h:
* libguile/init.c (scm_i_init_guile): Change arg to this internal
function from SCM_STACKITEM* to void*. Actually it's a
struct GC_stack_base*.
* libguile/bdw-gc.h: Don't do pthread redirects, because we don't want
to affect applications' pthread_* bindings.
* libguile/pthread-threads.h (scm_i_pthread_create)
(scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel)
(scm_i_pthread_sigmask): Do pthread redirects here, in this internal
header.
* libguile/threads.h: Remove declaration of internal
scm_i_with_guile_and_parent. Remove declaration of undefined
scm_threads_init_first_thread. Make declaration of internal
scm_threads_prehistory actually internal, and take a void* (actually a
struct GC_stack_base*).
* libguile/threads.c (GC_get_stack_base): Implement a shim if this
function is unavailable, and fold in the implementations of
get_thread_stack_base.
(GC_call_with_stack_base): Actually implement.
(guilify_self_1): Take a GC_stack_base* as an arg.
(scm_i_init_thread_for_guile): Likewise, and set up libgc for
registration of other threads.
(scm_init_guile): Use GC_get_stack_base instead of our own guesswork.
(with_guile_and_parent, scm_i_with_guile_and_parent): Rework to
trampoline through a GC_call_with_stack_base.
(scm_threads_prehistory): Pass the "base" arg on to guilify_self_1.
* libguile/continuations.c (scm_handler, c_handler)
(scm_c_with_continuation_barrier, scm_with_continuation_barrier): Call
scm_handle_by_message_noexit in the post-unwind handler, so that
dynwinds
* test-suite/tests/continuations.test ("continuations"): Add a test.
* module/system/repl/error-handling.scm (call-with-error-handling):
Do _not_ enter the debugger if the thrown key is in `pass-keys'.
Previously, for example, (throw 'quit) entered the debugger when run
from the REPL, despite the fact that 'quit is in `pass-keys'.
* libguile/snarf.h: New macro `SCM_SNARF_INIT_PREFIX'. (SCM_SNARF_INIT)
Use `SCM_SNARF_INIT_PREFIX' instead of including a literal marker. If
the preprocessor echoes #define directives to its output, this will
prevent `guile-snarf' from snarfing the `SCM_SNARF_INIT' definition
itself. Reported by Mike Gran <spk121@yahoo.com>.
* libguile/guile-snarf.in (modern_snarf): Don't output anything for
lines in which only one of the magic snarfing markers is present.
Modify the `sed' program for compatibility with POSIX `sed'. The new
`sed' program is based on a version by Wolfgang Jenkner
<wjenkner@inode.at>.
* test-suite/standalone/test-guile-snarf: New tests.
* libguile/threads.h: Always declare a scm_i_thread_key, for cleanup
purposes, in the BUILDING_LIBGUILE case.
* libguile/threads.c (scm_i_thread_key): Init with a cleanup handler, so
any guile-specific info for a thread can be cleaned up reliably.
(guilify_self_1): Always set the thread key.
(do_thread_exit_trampoline, on_thread_exit): Enter guile-mode for the
guile-mode cleanup handler, and trampoline through a
gc_call_with_stack_base for reasons explained in the code.
(init_thread_key, scm_i_init_thread_for_guile): Always init the key.
(scm_i_with_guile_and_parent): No need for pthread_cancel cleanup
handlers, as the pthread key destructor will take care of that for
us.
(really_launch): Remove needless pthread_exit call with incorrect
comment.
* test-suite/tests/i18n.test (%german-utf8-locale, %greek-utf8-locale):
New variables.
(under-german-utf8-locale-or-unresolved,
under-greek-utf8-locale-or-unresolved): Use them.
Thanks to Mark H Weaver <mhw@netris.org> for coming up with most of the
examples.
* test-suite/tests/i18n.test (%german-utf8-locale-name,
%greek-utf8-locale-name): New variables.
(under-german-utf8-locale-or-unresolved,
under-greek-utf8-locale-or-unresolved): New procedures.
("text collation (German)", "text collation (Greek)"): New tests
prefixes.
("string mapping")["string-locale-upcase German",
"string-locale-upcase Greek", "string-locale-upcase Greek (two
sigmas)", "string-locale-downcase Greek", "string-locale-downcase
Greek (two sigmas)"]: New tests.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-mb-regexp: New test, that the previous
patch fixed the abort() on fixup_multibyte_match.
* libguile/strings.c (scm_to_locale_stringn, scm_from_locale_stringn):
Use the encoding of the current locale, not of the current i/o ports.
Also use the current conversion strategy.
* doc/ref/api-data.texi (Conversion to/from C): Update docs.
* module/system/repl/command.scm:
* module/system/repl/debug.scm (terminal-width): Move terminal-width
here, make it thread-local, and export it.
(print-locals, print-frame, print-frames): Default width to
terminal-width.
* module/system/repl/error-handling.scm (call-with-error-handling): Add
`report' and `backtrace' on-error handlers.
* module/system/repl/common.scm (repl-default-options): Add on-error
REPL option, defaulting to `debug', but which may be changed.
* module/system/repl/repl.scm (run-repl): Pass the #:on-error REPL
option to call-with-error-handling.
* libguile/arrays.c (scm_i_read_array):
* libguile/backtrace.c (display_backtrace_body):
* libguile/filesys.c (scm_readdir)
* libguile/i18n.c (chr_to_case):
* libguile/ports.c (register_finalizer_for_port):
* libguile/posix.c (scm_nice):
* libguile/stacks.c (scm_make_stack): Clean up a number of
set-but-unused vars. Thanks to Douglas Mencken for the report.
* libguile/numbers.c (scm_log, scm_exp): Fix a few #if cases that should
be #ifdef.
* libguile/foreign.c (scm_pointer_to_scm, scm_scm_to_pointer): New
functions, useful to pass and receive SCM values to and from foreign
functions.
* module/system/foreign.scm: Export the new functions.
* doc/ref/api-foreign.texi (Foreign Variables): Add docs.
* test-suite/tests/foreign.test ("pointer<->scm"): Tests.
* test-suite/tests/control.test: Use c&e tests for most test blocks.
Note that this did not catch the recent bug.
("reified continuations"): Add a new test for capturing partial
continuations containing pending call frames. Before these would
contain dynamic links pointing out of the continuation segment, which
would not be relocated; now, the dynamic links are only made when the
frames are activated.
Thanks to Wolfgang J Moeller for the bug report and test case.
* libguile/vm-i-system.c (new-frame): Though it was appealing to set the
dynamic link here on the incomplete frame, we no longer do that, for
the reasons mentioned in the code.
(call, mv-call): Adapt to set the frame's dynamic link.
* libguile/vm-engine.c (vm_engine): Don't set dynamic link here, even
for boot program.
* libguile/frames.c (scm_frame_num_locals, scm_frame_local_ref)
(scm_frame_local_set_x): Fix up not-yet-active frame detection.
* module/rnrs/io/ports.scm (transcoder-eol-style)
(transcoder-error-handling-mode): Export these.
(textual-port?): Implement this procedure and export it.
* module/rnrs.scm: Export these here as well.
* module/rnrs/io/ports.scm (port-transcoder): Implement this procedure.
(binary-port?): Treat only ports without an encoding as binary ports,
add docstring.
(standard-input-port, standard-output-port, standard-error-port):
Ensure these are created without an encoding.
(eol-style): Add `none' as enumeration member.
(native-eol-style): Switch to `none' from `lf'.
* test-suite/tests/r6rs-ports.test (7.2.7 Input ports)
(8.2.10 Output ports): Test binary-ness of `standard-input-port',
`standard-output-port' and `standard-error-port'.
(8.2.6 Input and output ports): Add test for `port-transcoder'.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* libguile/r6rs-ports.c (scm_get_string_n_x): Implement `get-string-n!'
in C for efficiency.
* libguile/r6rs-ports.h: Add prototype for this function.
* module/ice-9/binary-ports.scm: Export `get-string-n!'.
* module/rnrs/io/ports.scm (get-string-n): Implement based on
`get-string-n!'.
Export both `get-string-n!' and `get-string-n'.
* module/rnrs.scm: Also export these.
* test-suite/tests/r6rs-ports.test (8.2.9 Textual input): Add a few
tests for `get-string-n' and `get-string-n!'.

* module/srfi/srfi-9.scm (define-inlinable): When inlining, evaluate the
arguments only once. Reported by Andreas Rottmann; thanks to Andy
Wingo for the elegant solution.
* test-suite/tests/srfi-9.test ("side-effecting arguments"): New test
prefix.
* libguile/init.c (stream_body, scm_standard_stream_to_port): Don't name
stdin, stdout, and stderr -- at least not as strings. That confuses
any code which tries to treat port-filename as a real filename, like
the syntax expander, or the `load' procedure/macro. Also this
behavior matches the docs now.
