* libguile/control.h:
* libguile/control.c (scm_c_abort): Add an implementation of `abort',
but it doesn't reify the continuation yet.
* libguile/vm-i-system.c (abort):
* libguile/vm.c (vm_abort): Wire up the call to `abort', avoiding
consing the args into a list.
* module/language/tree-il/compile-glil.scm (flatten): Add some compily
bits that can allow the abort to be resumed.
* module/language/tree-il.scm (<dynref>, <dynset>): New tree-il language
elements, corresponding to fluid-ref and fluid-set.
* module/language/tree-il/analyze.scm:
* module/language/tree-il/compile-glil.scm: Wire them up in the usual
manner.
* libguile/fluids.h (SCM_I_FLUID_P, SCM_I_FLUID_NUM)
(SCM_I_DYNAMIC_STATE_P, SCM_I_DYNAMIC_STATE_FLUIDS): Expose these
predicates and accessors, internally at least.
* libguile/fluids.c (IS_FLUID, FLUID_NUM, IS_DYNAMIC_STATE)
(DYNAMIC_STATE_FLUIDS): Implement in terms of the exposed macros.
* libguile/vm-engine.c (vm_engine): Cache the dynamic state in a local
var when we enter the VM.
* libguile/vm-i-system.c (wind-fluids, unwind-fluids): Use the cached
dynamic state instead of going through SCM_I_CURRENT_THREAD.
* libguile/control.h:
* libguile/control.c (scm_c_make_prompt, SCM_PROMPT_PRE_UNWIND_HANDLER):
* libguile/vm-i-system.c (prompt)
* module/language/tree-il.scm (<prompt> prompt-pre-unwind-handler):
* module/language/tree-il/analyze.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/inline.scm:
* module/language/tree-il/primitives.scm: Remove the "pre-unwind"
handler from prompt; it turns out not to be necessary. Adapt all
references.
* module/ice-9/psyntax.scm (build-dynlet, with-fluids): Use psyntax to
recognize `with-fluids' as a core form, producing <dynlet> if we are
compiling.
(sc-expand): To spice up the mix, use with-fluids here in the
implementation.
* module/ice-9/psyntax-pp.scm: Bootstrapped twice (!).
* module/ice-9/boot-9.scm: Remove with-fluids definition, it's in the
core now.
* libguile/tags.h (scm_tc7_with_fluids): Allocate a tc7 for
"with-fluids" objects, which will only live on the dynamic stack (wind
list), not in normal scheme-land.
* libguile/fluids.h (SCM_WITH_FLUIDS_P, SCM_WITH_FLUIDS_LEN)
(SCM_WITH_FLUIDS_NTH_FLUID, SCM_WITH_FLUIDS_NTH_VAL)
(SCM_WITH_FLUIDS_SET_NTH_VAL): Add some accessors.
* libguile/fluids.c (scm_i_make_with_fluids, scm_i_swap_with_fluids):
New internal functions.
(scm_c_with_fluids, scm_c_with_fluid): Push with-fluids objects on the
dynwind list, not winders.
* libguile/dynwind.c (scm_i_dowinds): Add cases for winding and
unwinding with-fluids objects.
* libguile/memoize.h (scm_sym_with_fluids, SCM_M_BEGIN): New public
data.
* libguile/memoize.c (scm_m_with_fluids): Define with-fluids as a
primitive syntax.
(unmemoize): Add with-fluids case.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Add with-fluids cases.
* test-suite/tests/fluids.test
("fluids not modified if nonfluid passed to with-fluids"): Enable a
now-passing test.
* module/ice-9/eval.scm: Add a comment explaining the frequencies of the
various memoized expression types.
(eval): Reorder the cases based the profile.
* libguile/memoize.h (scm_sym_at_dynamic_wind, SCM_M_DYNWIND)
* libguile/memoize.c (memoized_tags, MAKMEMO_DYNWIND)
(scm_m_at_dynamic_wind, unmemoize): Add dynwind as a primitive
expression type.
* libguile/dynwind.c (scm_dynamic_wind): Downgrade to a normal C
function.
* libguile/eval.c (eval):
* module/ice-9/eval.scm (primitive-eval): Add dynwind support.
* module/ice-9/r4rs.scm: More relevant docs.
(apply): Define in a more regular way.
(dynamic-wind): Add to this file, with docs, dispatching to
@dynamic-wind.
* module/language/tree-il/primitives.scm: Parse @dynamic-wind into a
tree-il dynamic-wind.
* configure.ac:
* doc/Makefile.am:
* doc/tutorial/ChangeLog-2008:
* doc/tutorial/ChangeLog-guile-doc-tutorial:
* doc/tutorial/Makefile.am:
* doc/tutorial/guile-tut.texi: Remove the tutorial. The history was out
of date (whereas the manual is current), the C examples are no longer
valid (and the manual does provide C examples), it was incomplete, and
its first person no longer hacks on Guile. So tutorial, you had a good
run, but the manual does your job now!
* doc/tutorial/guile-tut.texi (c_builtins.c): Fix a typo with an
undeclared variable. Thanks to Raimon Grau for the pointer. This
tutorial is quite out of date, though...
* module/system/base/compile.scm (compiled-file-name): Add a comment.
* module/ice-9/boot-9.scm (load): Avoid loading up (system base compile)
just to compute an autocompiled file name. Fixes the issue whereby
guile-tools snarf-check-and-output-texi was inadvertantly loading up
srfi-1, and thereby a stale library, just to see if guile-tools itself
had a compiled version.
Not sure what the right unit test is here, other than vigilance.
* configure.ac: Add check for `nl_item'.
* libguile/i18n.c: Separate check for `HAVE_LANGINFO_H' and
`HAVE_NL_TYPES_H'.
[!HAVE_NL_ITEM]: Define `nl_item'.
Thanks to Ken Raeburn.
* test-suite/tests/net-db.test ("getaddrinfo")["port 80"]: Fix bogus
check of `addrinfo:flags' (POSIX says that the "contents of the
ai_flags field of the returned structures are undefined.").
("wrong service name"): Accept `EAI_NONAME' as a valid error code.
