2004-10-29  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* unif.h, unif.c (scm_make_u1vector): New, but only temporary.
	(make_uve): Removed.
	(scm_i_proc_make_vector, scm_i_proc_make_string,
	scm_i_proc_make_u1vector): New.
	(scm_init_unif): Initialize them.
	(scm_i_convert_old_prototype): New.
	(scm_make_uve): Use it to get the creator procedure.  Removed all
	old code that created old-style uniform vectors.
	(scm_array_p): Handle generic vectors.
	(scm_dimensions_to_uniform_array): Do not fill new array with
	prototype when that is a procedure.
	(scm_list_to_uniform_array): Also accept a list of lower bounds as
	the NDIM argument.
	(scm_i_print_array): Print rank for shared or non-zero-origin
	vectors.
	(tag_proto_table, scm_i_tag_to_prototype, scm_i_read_array): New.
	(scm_raprin1): Do not call scm_i_array_print for enclosed arrays,
	which I do not understand yet.
	(scm_array_prototype): Explicitely handle generic vectors.
	
	* numbers.c, number.h (scm_i_print_complex, icmplx2str): New.
	(iflo2str): Use icmplx2str for complex numbers.

	* srfi-4.c, srfi-4.h (scm_i_read_homogenous_vector,
	scm_i_uniform_vector_prototype): Removed.
	(scm_i_uniform_vector_creator): New.
	(SCM_UVEC_C32, scm_c32vector, scm_make_c32vector, etc,
	SCM_UVEC_C64, scm_c64vector, scm_make_c64vector, etc): New.
	Updated all tables and generic functions to support them.
	(scm_i_proc_make_u8vector, scm_i_proc_make_s8vector, etc): New.
	(scm_init_srfi_4): Initialize them.
	
	* srfi-4.i.c (scm_take_u8vector, etc): use uvec_sizes instead of
	sizeof(CTYPE) as explained in the comment.

	* read.c (scm_lreadr): Call scm_i_read_array for all characters
	followinf '#' that can start an array.  Explicitely disambiguate
	'i' and 'e' between introducing numbers and uniform vectors.  Do
	not call scm_i_read_homogenous_vector, since that is also handled
	by scm_i_read_array now.

2004-10-27  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	First cut at integrating uniform vectors from srfi-4 with the rest
	of Guile.  This change replaces scm_tc7_byvect with a s8 uniform
	vector.  The plan is to gradually replace one type after the other
	until none is left and then to consider general cleanups and
	optimizations.
	
	* srfi-4.h, srfi-4.i.c (scm_u8vector_elements, etc): New.

	* srfi-4.h, srfi-4.c (scm_uniform_vector_p,

	from unif.h, unif.c and extended to handle both the old and new
	uniform vectors.

	* tags.h (scm_tc7_byvect): Commented out.

	* unif.h, unif.c (scm_uniform_vector_ref, scm_array_ref): Renamed
	the former to the latter.

	srfi-4.h, srfi-4.c.
	(scm_make_uve): Call scm_make_s8vector for #\nul prototype.
	(scm_array_p, scm_array_rank, scm_array_dimensions,
	scm_transpose_array, scm_enclose_array, scm_array_ref, scm_cvref,
	scm_array_set_x, scm_array_contents, scm_uniform_array_read_x,
	scm_array_to_list, scm_array_prototype): Handle srfi-4 uniform
	vectors.  Removed code for scm_tc7_byvect.
	(scm_dimensions_to_uniform_array): Fill array with 0 when
	prototype is #\nul.
	(scm_i_print_array_dimension, scm_i_legacy_tag,

	* gh_data.c (gh_chars2byvect): Reimplemented with
	scm_make_s8vector.
	(gh_scm2chars): Handle s8vectors, removed code for scm_tc7_byvect.

	* srfi-4.c (take_uvec): New.
	(alloc_uvec): Use it.
	* srfi-4.h, srfi-4.i.c (scm_take_u8vector, etc): New.

	* random.c (vector_scale, vector_scale_x): Renamed former to the
	latter, since it modifies its argument.
	(vector_scale_x, vector_sum_squares, scm_random_normal_vector_x):
	Do not use scm_universal_vector_length for non-uniform vectors.
	Use scm_f64vector_elements to access innards of uniform vectors.

	and made non-static.  Changed all uses.

2004-10-22  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* variable.c, threads.c, struct.c, stackchk.c, smob.c, root.c,
	print.c, ports.c, mallocs.c, hooks.c, hashtab.c, fports.c,
	guardians.c, filesys.c, coop-pthreads.c, continuations.c: Use
	scm_uintprint to print unsigned integers, raw heap words, and
	adresses, using a cast to scm_t_bits to turn pointers into
	integers.

	* unif.c: Include "libguile/print.h".

	* numbers.h, numbers.c (SCM_T_INTBUFLEN): Increased to cover
	scm_t_intmax values.
	(scm_uint2str): New, for scm_t_uintmax.
	(scm_iint2str): Argument type changed to scm_t_intmax,
	reimplemented in terms of scm_uint2str.
	
	* print.c, print.h (scm_uintprint): New, for printing
	scm_t_uintmax values.

	all references to scm_lt_* with just lt_*.  Include <ltdl.h>
	instead of <libguile-ltdl.h>.

2004-10-20  Marius Vollmer  <mvo@zagadka.de>

	* sort.c (quicksort): Copy pivot out of the array while
	constructing the partitions; it could get overwritten otherwise.
	Because of the ultimate insertion sort, this bug did not cause
	quicksort to fail, it just put all the burdon on the insertion
	sort and was thus very slow.  Thanks to Rolan Orre for reporting
	the slowness!
	
2004-10-19  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* numbers.c (scm_i_range_error): New.

	Roland Orre for reporting this!

	* gc-segment.c (scm_i_get_new_heap_segment): Limit size of new
	segment to scm_max_segment_size.

	better error message.

	* deprecated.c: Include discouraged.h and keywords.h.

	* read.c (scm_lreadr): Simply do (symbol->keyword (read)) after
	reading '#:' or ':'.  See NEWS for consequences.

2004-09-29  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* read.c (scm_lreadr): Revert change from 2004-09-22: string
	literals are now read-write again (until SCM_STRING_CHARS is
	removed).

	* strings.c (SCM_STRING_CHARS): Explicitely reject read-only
	strings with an error message that blames SCM_STRING_CHARS.
