+
+ (scm_m_letrec1): Removed. Part of the functionality is taken

+
+ (scm_m_letrec): Call 'transform_bindings'.

+ once to produce guile.texi for reference manual synchronization.
+
+2001-11-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

+
+ * numbers.c: Document macros to define when including
+ 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).
+
+ * tags.h (SIZEOF_SCM_T_BITS): Define it appropriately.
+
+ * __scm.h: Define HAVE_UINTPTR_T, HAVE_PTRDIFF_T and

+
+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.
+
+2001-11-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * script.c (scm_shell_usage, scm_compile_shell_switches): Prepend
+ 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.
+
+2001-11-05 Stefan Jahn <stefan@lkcc.org>
+
+ * struct.c (s_scm_struct_vtable_p): Corrected docstring.
+
+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.
+
+2001-11-03 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * eval.c (scm_m_begin): Allow `(begin)`, with no subforms.
+ (SCM_CEVAL): Evaluate an empty `begin' to SCM_UNSPECIFIED.
+
+2001-11-02 Mikael Djurfeldt <mdj@linnaeus>
+
+ * print.c (scm_iprin1): Mark print state as revealed when

+
+ * unif.c (scm_ra2contig): Fixed memory overwrite bug.
+
+2001-11-02 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Support for native Win32. Thanks to Stefan Jahn!
+
+ * Makefile.am: Add win32-uname.c, win32-uname.h, win32-dirent.c
+ 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.h: Defined SCM_API. This macro gets prepended to all
+ function and data definitions which should be exported or imported
+ in the resulting dynamic link library in the Win32 port.
+
+ * __scm.h, alist.h, arbiters.h, async.h, backtrace.h, boolean.h,
+ chars.h, continuations.h, coop-defs.h, coop-threads.h,

+ vports.h, weaks.h:
+ Prefixed each each exported symbol with SCM_API.
+
+ * continuations.c: Added comment about the use of the extern
+ declarations of {get,set}context() functions used in the ia64 port.
+
+ * continuations.h, gc.c: `__libc_ia64_register_backing_store_base'
+ is meant to be a `unsigned long *'.
+
+ * filesys.c: Include `direct.h' if possible. Use local
+ `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()'.
+
+ * fports.c: Include `io.h' is possible. Put `*fp' into referring
+ statement block in `scm_fport_buffer_add()'.
+ Some corrections in `getflags()'.
+
+ * gdb_interface.h (GDB_INTERFACE): Also support __CYGWIN__.
+
+ * guile.c: Make sure to define __SCM_IMPORT__ for shared library
+ build on Win32. Disable preloaded symbols on Win2 platforms.
+
+ * ioext.c, ports.c: Include `io.h' is possible.
+
+ * mkstemp.c: Include `process.h' is possible.
+
+ * net_db.c: Disable extern declaration of `h_errno' for __CYGWIN__,
+ too.
+ Put `scm_return_entry()' into HAVE_GETSERVENT conditional.
+
+ * posix.c: Remove unnecessary dirent includes and defines. Include
+ local `win32-uname.h' for MinGW. Extern declaration of
+ `mkstemp()' for systems where it does not exists. Make
+ `getlogin()' available on M$-Windows.
+
+ * scmsigs.c: Made `usleep()' avalable on MinGW.
+
+ * stime.c: On M$-Windows `tzname[]' is known to be `_tzname[]'.
+
+ * win32-dirent.c: Include "win32-dirent.h", not "dirent.h".
+
+ * win32-uname.c: Include "win32-uname.h", not "uname.h".
+
+2001-10-28 Mikael Djurfeldt <mdj@linnaeus>
+

+
+ (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.

+
+ * version.c (scm_version): use sprintf instead of snprintf,
+ for portability. thanks to Bill Schottstaedt.
+
+2001-10-14 Mikael Djurfeldt <mdj@linnaeus>
+
+ * read.c (scm_lreadr): When user-defined hash procedure returns
+ SCM_UNSPECIFIED: Fall back to standard handling instead of raising

+ interfering with parsing of numbers.)
+
+2001-10-13 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * numbers.c: Set NO_PREPRO_MAGIC when defining our version of

+
+2001-10-07 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * Makefile.am (EXTRA_libguile_la_SOURCES): Added "mkstemp.c".
+

+ * modules.c (module_variable): Pass over variables that exist but
+ are unbound.
+
+2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * backtrace.c (display_backtrace_file_and_line): Only use

+ Cramer.
+
+2001-10-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.c (mem2uinteger): Return number read so far when coming
+ 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.

+
+ (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

+ 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_iprlist): Removed a redundant SCM_IMP test.

+
+ (scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
+
+ (scm_procedure_name): Use SCM_CADR instead of explicit form.
+
+ (debugobj_print): Coerce scm_intprint arg 1 to long, not int.
+ Thanks to Rob Browning for the patch (see log entry 2001-09-21) -

+
+2001-10-09 Dirk Herrmann <D.Herrmann@tu-bs.de>

+
+2001-10-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * hashtab.c (scm_hash_fn_create_handle_x): The result of assoc_fn
+ is known to be #f if no entry is found. Thus, use !SCM_FALSEP
+ instead of SCM_NIMP to test for that case.
+
+ * strings.h (SCM_SET_STRING_LENGTH): Cast the length to

+
+2001-10-06 Marius Vollmer <mvo@zagadka.ping.de>

+ Use them to make these macros computable by the preprocessor.
+
+ * num2integral.i.c (INTEGRAL2NUM): Let the preprocessor test
+ whether the integral type fits in a fixnum, not the compiler.
+ This removes a spurious compiler warning. Also, honor the
+ NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is

+ These changes fixes a race condition in the Guile coop - pthread
+ compatibility code.
+
+ * coop.c (mother_awake_p): New variable.
+ (coop_create): Set mother_awake_p before creating or signalling
+ mother; wait until mother is going to sleep before returning.
+ (mother): Reset mother_awake_p before going to sleep.
+
+2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * options.c (protected_objects, scm_init_options): The content of
+ protected_objects is now protected from garbage collection using
+ scm_gc_register_root instead of scm_permanent_object.
+
+ (get_option_setting): New static function that computes an option
+ setting as it was formerly done in the function scm_options.
+
+ (get_documented_option_setting): New static function that
+ returns option documentation as it was formerly done in the
+ function scm_options. Note that documentation C strings are no
+ longer precomputed into SCM objects. Instead, they are converted
+ into SCM strings every time get_documented_option_setting is
+ called.
+
+ (change_option_setting): New static functions that modifies the
+ option setting as it was formerly done in the function
+ scm_options. The function is now exception safe, i. e. won't
+ cause a memory leak when interrupted. Further, only non-immediate
+ option values are added to the protection list.
+
+ (scm_options): This function now has only the purpose to dispatch
+ to to get_option_setting, get_documented_option_setting or
+ change_option_setting, depending on the arguments given to
+ scm_options.
+
+ (scm_init_opts): Don't convert documentation C strings into SCM
+ strings. Further, don't protect any object values: They _must_
+ be immediate values, otherwise there is no guarantee that they
+ have not been collected before anyway.
+
+ * options.[ch] (scm_t_option): Made type unsigned, name into a
+ constant char* and val into a scm_t_bits type.
+
+ (scm_options, scm_init_opts): The number of options is guaranteed
+ to be larger or equal to zero. Thus, the type is changed to
+ unsigned.
+
+2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * num2integral.i.c (NUM2INTEGRAL): Eliminated some warnings about
+ testing an unsigned value for being >= 0.
+
+2001-10-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * numbers.h: Removed old comment about using SCM_CAR to access
+ non-pair cells.
+
+ (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
+ the return value is signed. Thanks to Brian Crowder for the bug
+ report.
+
+ (SCM_SRS): Avoid unnecessary casting and don't unpack input
+ values. With this patch, SCM_SRS can be safely used for other
+ types than scm_t_signed_bits. However, it should still better be
+ an internal macro and thus be renamed to SCM_I_SRS.
+
+ (SCM_MAKINUM, SCM_INUM): Use proper casting.
+
+2001-10-03 Gary Houston <ghouston@arglist.com>
+
+ * continuations.h, unif.h: in the descriptions of the bit patterns
+ of the heap cells, make bit 0 the least significant.
+
+2001-09-25 Thien-Thi Nguyen <ttn@glug.org>
+
+ * chars.h (SCM_MAKE_CHAR): Use `scm_t_bits' instead of `intptr_t'.
+ Thanks to Golubev I. N.
+
+2001-09-25 Gary Houston <ghouston@arglist.com>
+
+ * ports.c (scm_drain_input): extended the docstring. thanks to
+ Alex Schroeder and Thien-Thi Nguyen.
+
+2001-09-23 Mikael Djurfeldt <mdj@linnaeus>
+
+ * validate.h (SCM_NUM2FLOAT, SCM_NUM2DOUBLE,
+ SCM_VALIDATE_FLOAT_COPY, SCM_VALIDATE_DOUBLE_COPY): New
+ macros. (The NUM names might soon change.)
+
+ * numbers.h: Added missing declarations.
+
+2001-09-22 Mikael Djurfeldt <mdj@linnaeus>
+
+ * Makefile.am: Distribute num2float.i.c.
+
+ * num2float.i.c: New file, multiply included by numbers.c, used
+ to "templatize" the float <-> num conversion routines.
+
+ * numbers.c: New functions: scm_num2float, scm_float2num,
+ scm_num2double, scm_double2num.
+
+2001-09-21 Rob Browning <rlb@defaultvalue.org>
+
+ * .cvsignore: really add version.h
+
+ * strings.h (SCM_SET_STRING_LENGTH): coerce "l" to a long.
+ Otherwise it fails on the alpha. However, we might rather choose
+ this size conditionally.
+
+ * numbers.c (scm_gcd): change "k" to a long from an int.
+ Otherwise it fails on the alpha. However, we might rather choose
+ this size conditionally.
+
+ * error.c (scm_wta): coerce char* to intptr_t before int
+ assignment.
+
+ * debug.c (debugobj_print): coerce scm_intprint arg 1 to long, not
+ int.
+
+ * chars.h (SCM_MAKE_CHAR): coerce value to intptr_t.
+
+2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
+
+ * numbers.c (scm_integer_expt): Accept inexact integer in second
+ argument. (Thanks to Bill Schottstaedt.)
+
+2001-09-20 Rob Browning <rlb@defaultvalue.org>
+
+ * .cvsignore: add version.h
+
+ * versiondat.h.in: removed (obsolete).
+
+ * version.h.in: renamed from version.h.
+ (SCM_GUILE_MAJOR_VERSION): new public macro.
+ (SCM_GUILE_MINOR_VERSION): new public macro.
+ (SCM_GUILE_MICRO_VERSION): new public macro.
+
+ * version.h: renamed to version.h.in.
+
+ * version.c
+ (scm_major_version): support integer *_VERSION macros.
+ (scm_minor_version): support integer *_VERSION macros.
+ (scm_micro_version): support integer *_VERSION macros.
+ (scm_version): support integer *_VERSION macros.
+
+2001-09-20 Mikael Djurfeldt <mdj@linnaeus>
+
+ * error.c, error.h: Made error keys globally accessible.
+ Applications might want to test for these or use them in a direct
+ call to scm_error.
+
+ * num2integral.i.c (NUM2INTEGRAL): Report an error when these
+ routines are passed an inexact. This change in behavior is
+ motivated by concordance with R5RS: It is more common that a
+ primitive doesn't want to accept an inexact for an exact.
+
+2001-09-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ The following patch partially undoes my patch from 2001-06-30,
+ where I added the function scm_gc_mark_cell_conservatively. The
+ function is buggy, since it breaks guile during conservative
+ marking if a pointer on the stack points directly into the list of
+ free cells on the heap: With conservative cell marking this will
+ cause the whole free list to be scanned and marked - boom!
+
+ * gc.c (allocated_mark, MARK, heap_segment,
+ scm_gc_mark_cell_conservatively, scm_init_storage), gc.h
+ (scm_gc_mark_cell_conservatively): Remove function
+ scm_gc_mark_cell_conservatively and update the corresponding
+ comments and uses accordingly. Thanks to Christopher Cramer for
+ the patch. (Minor corrections by me.)
+
+2001-09-15 Gary Houston <ghouston@arglist.com>
+
+ * root.h (scm_root_state): removed the continuation_stack and
+ continuation_stack_ptr members, which have no apparent purpose.
+ (scm_continuation_stack, scm_continuation_stack_ptr): #defines
+ removed.
+
+ * root.c (root_mark), init.c (restart_stack, start_stack), gc
+ (scm_igc): remove all references to contination_stack and
+ continuation_stack_ptr, avoiding allocation of a vector and
+ useless processing during gc.
+
+2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * guardians.c (tconc_t, t_tconc): Renamed tconc_t to t_tconc.
+
+ (TCONC_IN): Make sure that the cell word 0 is initialized last.
+
+ (guardians_t, t_guardians): Renamed guardians_t to t_guardians.
+
+ (GUARDIAN, GUARDIAN_DATA): Renamed GUARDIAN to GUARDIAN_DATA.
+
+ (guardian_apply, scm_get_one_zombie, scm_make_guardian,
+ mark_and_zombify): Prefer !SCM_<foo> over SCM_N<foo>.
+
+2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * guardians.c (mark_dependencies_in_tconc,
+ whine_about_self_centered_zombies, scm_init_guardians): Register
+ the static global variable `self_centered_zombies' via
+ scm_gc_register_root, to make some cdr-ing unnecessary.
+
+2001-09-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
+
+ * backtrace.c (display_backtrace_file,
+ display_backtrace_file_and_line): Use SCM_EQ_P when comparing SCM
+ values, use SCM_FALSEP when comparing SCM values against #f.
+ Thanks to Rob Browning for the bug report.
+
+2001-09-12 Martin Baulig <martin@home-of-linux.org>
+
+ * strings.[ch] (scm_str2string): New function.
+
+2001-09-06 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gc.c (scm_done_free): Always subtract size from scm_mallocated
+ when computing nm, even if it's negative.
+ (scm_must_malloc): Abort on overflow of scm_mtrigger.
+ (scm_must_realloc): Likewise.
+
+2001-09-01 Michael Livshin <mlivshin@bigfoot.com>
+
+ * numbers.c (scm_sys_check_number_conversions): new function,
+ defined if Guile is compiled in debugging mode. currently checks
+ `scm_num2ulong', should check much much more.
+
+ * num2integral.i.c (NUM2INTEGRAL): when converting a bignum to
+ unsigned, ensure that it's positive. thanks to Martin Baulig!
+
+2001-08-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
