[bpt/guile.git] / libguile / ChangeLog

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

	* sort.c (quicksort, scm_merge, scm_merge_list_x,
	scm_merge_list_step, scm_merge_vector_step): Inserted SCM_TICKs at
	strategic places so that the loops can be interrupted.

	* Makefile.am (INCLUDES): Use @LTDLINC@ instead of
	"-I$(top_srcdir)/libguile-ltdl".
	(libguile_la_LIBADD): Use @LIBLTDL@ instead of
	"../libguile-ltdl/libguile-ltdl.a".
	
	* guile.c, dynl.c: Switched to using libltdl directly.  Replaced
	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.
	* conv-integer.i.c, conv-uinteger.i.c: Use it instead of
	scm_out_of_range.	

	* sort.c (scm_restricted_vector_sort_x): Validate startpos <=
	endpos.  State inclusiveness/exclusiveness of bounds in docstring.

	* unif.c (scm_array_p): When no prototype is given, explicitely
	test for allowable types, do not simply return true.  Thanks to
	Roland Orre for reporting this!

	* private-gc.h (SCM_DEFAULT_MAX_SEGMENT_SIZE): Increase to 20 Mib.

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

	symbol with their real name.

	(SCM_KEYWORDP, SCM_KEYWORDSYM): Deprecated and implemented in
	terms of scm_is_keyword and scm_keyword_dash_symbol.

	* keywords.c (scm_symbol_to_keyword): Use SCM_ASSERT_TYPE for a
	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.

	* options.c (change_option_setting): Use scm_car instead of
	explicit type check plus SCM_CAR.
