handle-system-error): Backtracing now works for signals aswell;
Backtracing mechanism can now identify the stack root created by
start-stack so that the user isn't exposed to system stack frames.
throw-handler-default.
((handle-system-error key . arg-list)): Changed the way errors are
reported.
((scm-style-repl)): Wrap up the call to eval in a start-stack
acro.
((error-catching-loop thunk)): Introduce a lazy-catch into
error-catching-loop so that the stack can be captured.
make-vector fill new vectors with '(); this will make it easier to
port Guile Scheme code to other Schemes.
* boot-9.scm (make-print-style, make-print-table): Same.
Append "." to the default %load-path.
(feature?): new function: checks for a symbol in the features list.
(module-local-variable): remove apparently useless (caddr (list m v
...))
(%load-announce): minor formatting change.
(file-exists?): use access? if posix is featured.
(file-is-directory?): use stat if i/o-extensions is featured.
(try-module-autoload module-name): use file-exists? before
file-is-directory?
to 'misc-error instead of 'error (no need to distinguish these.)
Don't set up 'error as a key.
Set up regex-error as a key, if regex is available.
(signal-handler): use scm-error, not throw.
(%try-load, try-load-with-path, %load, load-with-path,
basic-try-load-with-path, basic-load-with-path,
try-load-module-with-path,load-module-with-path): deleted, since
they seem redundant.
(try-load): define using %try-load, not try-load-with-path.
(load): rewritten. load tries to open the file directly and
with a .scm extension before searching the library directories
(should "." be added to %load-path? then load could still open
directly files starting with "/").
(try-module-autoload): use load, not load-with-path.
(%load-indent): deleted, -2 was causing errors.
(%read-sharp): use port-line, not line-number.
%try-load itself was the primitive.
(load-with-path): use scm-error instead of %load-announce-lossage.
Errors are thrown to 'misc-error instead of 'could-not-load.
(%load-announce-lossage): deleted.
SCM-style errors. handle the case that an unexpected number
of args are supplied.
(%%system-errors): removed.
(error): redefine using a throw with key and 4 args.
('error): associate 'error, 'error-signal keys with
%%handle-system-error.
(%%default-error-handler): removed.
(signal-handler): throw with 4 args and use the error-signal key.
Create an error message instead of using numerical codes.
(%%bad-throw): call error instead of throw if key not found.
* boot-9.scm: initialize new error keys (see libguile/ChangeLog).
(%%handle-system-error key): check subr is not #f before printing.
Recognize %s (embed an argument using "display") and
%S (embed an argument using "write").
* PLUGIN/guile.config (xtra_dependencies): add only libgh.a.
(xtra_cflags): just add -L../lgh
* PLUGIN/guile.libs: try -lgh -lguile
* Makefile.am (INCLUDES): add -I../ so that libguile/scmconfig.h can
be found when srcdir != build dir.
* PLUGIN/REQ: remove the "ice-9 lgh" line which causes a cycle.
* error.c, error.h: setup scm_num_overflow key.
* __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
Remove definition of SCM_OVSCM_FLOW.
* fports.c (scm_open_file): use SCM_SYSERROR_M.
* __scm.h: SCM_SYSERROR_M: new macro for system errors with an
explicit message and args.
* error.c, error.h, __scm.h: change system_error_sym to
scm_system_error.
* error.c (system_error_sym): remove leading %% from the Scheme name
"%%system-error".
* __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
* boot-9.scm: remove leading %% from references to '%%system-error.
(%%handle-system-error): don't pass all the thrown arguments when
aborting, just the key and subr.
Remove the code to "Install default handlers for built-in errors."
Remove the definition of the syserror procedure.
Associate 'numerical-overflow with default handler.
resolved-ref --> nested-ref Motivation: conformance to the other
dictionary operators: list-ref operates on list, vector-ref
operates on vector, nested-ref operates on nested namespace,
local-ref operates on the local nested namespace.
(implementation-vicinity, parse-path): Deleted, along with code to
initialize %load-path.
* boot-9.scm (in-vicinity): If the vicinity doesn't end with a
"/", use one to separate it from the file.
Add the directory named after the version number.
Prepend the version number to the other directories in the path.
Simplify by mapping the common prefix onto each item.
* Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
sitedatadir): New definitions.
(libparent, libdir, install_path): Replaced by above.
(install): Create the above directories.
Put the source files into subpkgdatadir.
(uninstall): Remove the above directories.
Makefile's distribution and installation targets; just put it all
in the Makefile directly.
* PLUGIN/this.configure (scm_files, aux_files): Remove sections
for these.
* configure.in: Remove code that gets and substitutes scm_files and
aux_files.
* Makefile.in (scm_files, aux_files): Write out the list of files
here, where people expect to find them.
