num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
now rely on SIZEOF_ macros that have been figured out at
configure time.
* num2integral.i.c: Adapt to new interface.
(NUM2INTEGRAL): Test whether a fixnum can be represented in the
target type by casting it and checking whether it is still the
same. Do not try to handle bignums for integral types that are
smaller than fixnums. When handling bignums, collect the
magnituse first into a unsigned type, and correctly check for
overflow.
(INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
only -MIN_VALUE can still be negative of all negative numbers (in
twos-complement).
* configure.in: Include `win32-socket.o' in the list of object
files if networking is enabled on Win32.
2001-11-07 Stefan Jahn <stefan@lkcc.org>
* win32-socket.[ch]: New files. Defines Winsock-API error codes
and makes them available through Guile. That is because the
Winsock-API does not store its errors in `errno' and thus cannot
return error messages via `strerror (errno)'.
* socket.c (scm_init_socket): Initialize `win32-socket' part
here under M$-Windows.
* numbers.h: Added missing declaration of
`scm_sys_check_number_conversions()'.
* error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
and use in `(strerror)' and `(system-error)'.
* Makefile.am (EXTRA_libguile_la_SOURCES): Added
`win32-socket.[ch]' to extra source and header files.
a call to turn-on-debugging when --debug has been given instead of
turning it on directly. Also, handle new `--no-debug' option,
which might suppress the call to turn-on-debugging.
* NEWS: Corrected remarks about SCM_API.
* configure.in: Defining USE_DLL_IMPORT definition to indicate
usage of DLL import macros in `libguile/__scm.h'.
(LIBOBJS): Removed `fileblocks.o' from the list of object files.
Somehow Jim Blandy's patch from 1997 did not survive.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* configure.in (EXTRA_DEFS): Follow-up patch. Using SCM_IMPORT
instead of __SCM_IMPORT__.
* readline.c (scm_readline_init_ports): Disable input/output
stream redirection for Win32. The readline package for Win32
does not support this. The guile-readline library works fine
for command line editing.
* readline.h (SCM_RL_API): Renamed __FOO__ macros into FOO.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* Makefile.am (libguile_la_LIBADD): Added $(THREAD_LIBS_LOCAL)
here (was at guile_LDADD) which describes the dependency
correctly and allows a clean build on Win32.
* __scm.h (SCM_API): Follow-up patch. Renamed __FOO__ macros
into FOO.
* __scm.h: USE_DLL_IMPORT indicates the usage of the DLL
import macros for external libraries (libcrypt, libqthreads,
libreadline and libregex).
* coop-defs.h: Include <winsock2.h> for `struct timeval'.
* posix.c (flock): Added support for flock() in M$-Windows.
* guile.c (SCM_IMPORT): Follow-up patch. Use SCM_IMPORT instead
of __SCM_IMPORT__.
* fports.c (getflags): Differentiate reading and writing pipes
descriptors.
* filesys.c (S_IS*): Redefine all of the S_IS*() macros for
M$-Windows.
* coop.c (coop_condition_variable_timed_wait_mutex): Use
conditionalized error code if `ETIMEDOUT' is not available.
(scm_thread_usleep): Remove bogus declaration of `struct timeval
timeout'.
* numbers.c (PTRDIFF_MIN): Moved this definition where it actually
belongs. That is because NO_PREPRO_MAGIC gets undefined after
each inclusion of `num2integral.i.c'.
(SIZE_MAX): Define NO_PREPRO_MAGIC if SIZE_MAX is undefined.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* md/Makefile.am (EXTRA_DIST): Added `i386.asm'.
* md/i386.asm: New file. Contains the Intel syntax version for
nasm/tasm/masm of the file `i386.s'.
* qt.h.in: Definition of QT_API, QT_IMPORT and QT_EXPORT.
Prefixed each symbols which is meant to go into a DLL.
* Makefile.am (libqthreads_la_LDFLAGS): Put `-no-undefined'
into LDFLAGS to support linkers which do not allow unresolved
symbols inside shared libraries.
(EXTRA_DIST): Add `libqthreads.def', which is an export file
definition for M$-Windows. It defines exported symbols. This is
necessary because the M$VC linker does not know how to export
assembler symbols into a DLL.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* srfi-13.h, srfi-14.h, srfi-4.h: Follow-up patch. Renamed
__FOO__ macros into FOO.
2001-11-04 Stefan Jahn <stefan@lkcc.org>
* tests/ports.test: Run (close-port) before (delete-file) if
necessary/advisory.
`win32-dirent.h' for the native M$-Windows port. Define S_IS*()
macros for M$-Windows. Implementation of `fstat_Win32()' which is
able to differentiate between sockets and other file descriptors.
Use this function as wrapper in `scm_fstat()'. Fixed typo in
`scm_dirname()'.
and win32-dirent.h to extra source and header files. These
include the uname() and the POSIX dirent interface implementation
for M$-Windows. Put `-no-undefined' into LDFLAGS to support
linkers which do not allow unresolved symbols inside shared
libraries. Corrected `guile_filter_doc_snarfage$(EXEEXT)'
dependency.
scm_m_define, scm_m_letrec1, scm_m_let, scm_m_expand_body,
scm_macroexp, unmemocopy, scm_eval_args, scm_deval_args,
SCM_CEVAL, scm_map, scm_init_eval): When building lists, prefer
scm_list_<n> over scm_cons[2]?.
(scm_unmemocar, scm_m_cond, scm_m_letstar, scm_m_letrec1,
scm_m_let, scm_m_atbind, unmemocopy, SCM_CEVAL, SCM_APPLY): Use
SCM_C[AD][AD]R instead of explicit form.
(scm_m_set_x, scm_m_cond, scm_m_letstar, scm_m_do): Reordered
comparison parameters.
(scm_m_case, scm_m_cond, scm_m_letstar, scm_m_do, SCM_CEVAL): Use
!SCM_NULLP instead of SCM_NIMP.
(scm_m_case): Don't copy the form. Renamed proc to clause and
minimized its scope. Renamed x to clauses. Removed side
effecting operation from macro call.
(scm_m_cond): Don't copy the form. Renamed arg1 to clause and
minimized its scope. Renamed x to clauses. Minimized the scope
of variable 'len'. Make sure the else clause is treated specially
even in case of '=>' occurences. Don't change the else to #t in
order to be able to distinguish this case in the evaluator. Leave
type checking of the recipient to the evaluator.
(scm_c_improper_memq): Made the comment somewhat clearer.
(scm_m_lambda): Renamed proc to formals. Removed unnecessary
test for SCM_IM_LET at the place of the formal parameters.
Simplified the formal parameter checking.
(scm_m_letstar): Added Comment. Renamed proc to bindings.
Renamed arg1 to binding and minimized its scope. Eliminated
unnecessary consing.
(scm_m_do): Renamed proc to bindings. Minimized the scope of
variable 'len'.
(build_binding_list): New static function.
(unmemocopy): Don't use SCM_TYP7 on pairs (it's unclean).
Further, split up the 'letrec' unmemoizing code to the
corresponding parts for 'do', 'let' and 'letrec', adding comments
to each form. Cleanup the handling of the do form (This removes
some *real* code :-).
(SCM_CEVAL): Removed side effecting operation from macro call.
Handle the 'else clause of the 'cond form specially - the symbol
'else is not replaced with #t any more.
SCM_UNSPECIFIED: Fall back to standard handling instead of raising
an exception. (This prevents parsing of uniform vectors from
interfering with parsing of numbers.)
* arrays.scm (read:uniform-vector): Return *unspecified* instead
of raising an exception if hash extend character isn't followed by
the array list. (This prevents parsing of uniform vectors from
interfering with parsing of numbers.)
across a hexdigit after having read a # or if not reading a hex
value. This will enable the calling code to correctly handle
forms like 1e2. (The background is, that the exponent markers d,
e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
providing this patch.
(mem2complex): Fix erroneous double-negation. Now, numbers like
1-i will be read correctly.
Initialize. These variables are now registered as gc roots.
(scm_current_pstate): Update documentation.
(scm_current_pstate, scm_make_print_state, scm_free_print_state,
scm_prin1, scm_init_print): print_state_pool is registered as a
gc root and thus does not need to be protected by a surrounding
pair any more.
(make_print_state): The car of print_state_pool no longer holds
the scm_print_state_vtable.
(scm_current_pstate, scm_make_print_state, print_circref,
scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
SCM_N<foo>.
(scm_prin1): When building lists, prefer scm_list_<n> over
scm_cons[2]?.
(scm_iprlist): Removed a redundant SCM_IMP test.
(scm_simple_format): Use SCM_EQ_P to compare SCM values.
