* doc/ref/goops.texi (Introductory Remarks): Node deleted, with
material moved to...
(The Metaobject Protocol): ...here.
(MOP Specification): Moved to become a subnode of `The Metaobject
Protocol'.
It is with a sigh that I do this. Farewell, old friend GDS; your bits
will live on, reclaimed and reused in the new debugger.
* module/Makefile.am:
* module/ice-9/gds-client.scm:
* module/ice-9/gds-server.scm: Remove these; we favor Geiser now.
* emacs/Makefile.am:
* emacs/gds-faq.txt:
* emacs/gds-scheme.el:
* emacs/gds-server.el:
* emacs/gds-test.el:
* emacs/gds-test.sh:
* emacs/gds-test.stdin:
* emacs/gds-tutorial.txt:
* emacs/gds.el: Remove GDS files. The docs are still around, as they
need to be folded into the docmentation of the new debugger.
* module/ice-9/debugger.scm:
* module/ice-9/debugger/command-loop.scm:
* module/ice-9/debugger/commands.scm:
* module/ice-9/debugger/state.scm:
* module/ice-9/debugger/trc.scm:
* module/ice-9/debugger/utils.scm:
* module/ice-9/debugging/breakpoints.scm:
* module/ice-9/debugging/example-fns.scm:
* module/ice-9/debugging/ice-9-debugger-extensions.scm:
* module/ice-9/debugging/load-hooks.scm:
* module/ice-9/debugging/steps.scm:
* module/ice-9/debugging/trace.scm:
* module/ice-9/debugging/traps.scm:
* module/ice-9/debugging/trc.scm: Remove these files, as we will favor
the REPL's implementation of a debugger, and (system vm traps) and
(system vm trap-state). But these old files will continue to inspire
the rest of the new debugger interface.
* libguile/eval.c: Mark "breakpoints", "trace", and "procnames" debug
options as obsolete. There is lots of work left to do here, though.
* libguile/srcprop.h (scm_sym_breakpoint)
(scm_c_source_property_breakpoint_p, SRCBRKP): Remove these
definitions, without replacements.
* libguile/srcprop.c: Remove all code that has to do with breakpoints.
* module/system/vm/coverage.scm (with-code-coverage): Switch current
thread to VM, using `set-thread-vm!'.
* test-suite/tests/coverage.test ("procedure-execution-count")["called
from C"]: New test.
* module/system/vm/traps.scm (frame-matcher): New helper.
(trap-at-procedure-call, trap-in-procedure, trap-in-dynamic-extent)
(trap-calls-in-dynamic-extent, trap-instructions-in-dynamic-extent)
(trap-instructions-in-procedure, trap-at-procedure-ip-in-range): Add
ability to trap on procedures that are closures.
(trap-at-source-location): Check source-closures first, to catch
source locations that are in nested procedures.
* module/system/xref.scm (*closure-sources-db*): New global, like
*sources-db* but for nested procedures. It's a separate map because
these procs need to be treated differently in trap handlers -- you
match on the bytecode, not on the program object.
(add-source, forget-source): Take the db as an argument (the normal db
or the closures db).
(add-sources, forget-sources): Record sources for nested procedures to
in *closures-db*.
(untaint-sources, ensure-sources-db): Adapt for new closures db.
(lookup-source-procedures): Factored out.
(source-closures): New exported procedure, returns closures at the
given source location.
Reported by Göran Weinholt <goran@weinholt.se>.
* libguile/r6rs-ports.c (scm_lookahead_u8): Return an unsigned byte.
* test-suite/tests/r6rs-ports.test ("7.2.8 Binary Input")["lookahead-u8:
result is unsigned"]: New test.
* test-suite/tests/weaks.test: Enclose in a module.
(valid?): New procedure.
("weak-hash")["weak-key dies, "weak-value dies", "double-weak dies"]:
Check that all the values are `valid?', in addition to checking that
at least one of them is #f.
* libguile/hashtab.c (scm_hash_fn_set_x): Register a disappearing link
to VAL when TABLE is weak-value.
* test-suite/tests/weaks.test ("weak-hash")["weak-key dies", "weak-value
dies", "doubly-weak dies"]: Use `hash-set!' and `hash-ref', not
`hashq-set!' and `hashq-ref', otherwise these tests would always
succeed because (eq? "this" "this") => #f.
["lives"]: Use `hash-ref' and `hash-set!' too for consistency.
* module/system/vm/trap-state.scm (add-trap-at-source-location!): New
proc.
* module/system/repl/command.scm (break-at-source): New repl
meta-command. Doesn't work as well as it could now because it doesn't
know about nested functions, but that's coming.
* module/system/vm/trap-state.scm (list-traps): Just return the integers
identifying the traps; people can use trap-name to get the names.
* module/system/repl/command.scm (traps): Adapt.
* module/system/vm/trace.scm (print-application, print-return): Add a
prefix before the printout.
(trace-calls-to-procedure, trace-calls-in-procedure): Add prefix
keyword args.
* module/system/vm/trap-state.scm (add-trace-at-procedure-call!): Give a
useful prefix for tracepoint printouts.
* module/system/vm/trace.scm (print-return, print-application)
(frame-return-values): Factored out of other things.
(trace-calls-to-procedure): New proc, installs a trap tracing only
calls to the given proc.
(trace-calls-in-procedure): Refactor a bit.
* module/system/vm/trap-state.scm (add-trace-at-procedure-call!): New
proc.
* module/system/repl/command.scm (tracepoint): New command, installs a
tracepoint on a procedure.
* module/system/vm/trap-state.scm (with-default-trap-handler): Don't
enable traps if we are setting a handler of #f.
* module/system/repl/error-handling.scm (call-with-error-handling): Add
#:trap-handler arg.
* module/system/repl/repl.scm (run-repl): Only have traps enabled while
running the thunk. Otherwise we trace on procedures called as part of
the repl.
* module/system/vm/traps.scm (trap-frame-finish): Use frame-address
instead of frame-dynamic-link.
(trap-calls-to-procedure): New proc, traps on procedure calls and
their corresponding returns.
* module/system/vm/traps.scm (trap-frame-finish)
(trap-in-dynamic-extent, trap-calls-in-dynamic-extent)
(trap-instructions-in-dynamic-extent): New traps, for implementing
tracing, and the `finish' command.
* module/system/vm/trace.scm (trace-calls-in-procedure)
(trace-instructions-in-procedure): New tracing traps.
(vm-trace): Reimplement in terms of the new traps.
* module/system/vm/trap-state.scm (add-trap!): New helper; not used in
this commit, though.
* doc/ref/goops.texi (Built-in classes): New node.
(User-defined classes): Show is-a? v and class-of v here, instead of
in next node.
(Asking for the class of an object): Deleted, no longer needed.
* doc/ref/goops.texi (Quick Start): Remove words that only reiterate
"quick start".
* doc/ref/goops.texi (Methods, User-defined classes, Asking for the
class of an object): Say "class" instead of "type". They
are called classes elsewhere, and in an object-oriented system, people
expect classes!
So as to enable more free refactoring of the rest of the chapter
* doc/ref/goops.texi (Copyright Notice): New section containing the
Stk copyright.
* doc/ref/goops-tutorial.texi (Copyright): Equivalent section here
deleted.
* module/system/repl/command.scm (profile, trace, inspect)
(pretty-print): Use repl-prepare-eval-thunk instead of the lower-level
compile and make-program.
* module/system/vm/traps.scm (new-disabled-trap): Don't manipulate the
VM trace level in the enable and disable handlers. Unfortunately, this
makes traps not work unless you enable hooks, but given that
vm_dispatch_hook has to set trace-level to 0, there needs to be an
object with a broader view of what traps are enabled. That object is
the hook state.
* module/system/vm/trap-state.scm (trap-state->trace-level): New
procedure.
(with-default-trap-handler): Add an optional trap-state argument. Now
makes sure that the vm-trace-level is set appropriately during the
execution of the thunk, allowing for breakpoints from recursive
prompts.
* module/rnrs/syntax-case.scm: Add make-variable-transformer to the
imports. This was causing an unbound variable error even though
(rnrs) had been imported.
