+
+ Generalize casefiles to the extent that we can use them for
+ sorting and other kinds of data transformations. Change cases to
+ be copy-on-write to improve memory efficiency in common cases.
+ Every access to a member of a `struct ccase' was changed to be a
+ call to a case_*() function, especially case_data(), case_num(),
+ case_str(), or case_data_rw(). Many instances of a local variable
+ named "case_num" were changed to "case_idx" as a consequence.
+ Many `struct ccase *' were changed to actual `struct ccase'
+ because of copying semantics of cases. In several places there
+ was a choice between updating debug code to work with the new ADTs
+ or just deleting it because it was useless; I chose to delete it.
+
+ * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
+
+ * case.c: New file.
+
+ * case.h: New file.
+
+ * aggregate.c: (struct agr_proc) Change type of `sort' to
+ sort_criteria *. Add `break_vars', `break_var_cnt' members.

+
+ * alloc.h: Prototype out_of_memory().
+
+ * casefile.c: Switched from a linked list in-memory representation
+ to a two-level array-style representation. The linked list was
+ appropriate when we could stick a header onto cases, but that's no
+ longer the case. Also, the two-level array will allow for random
+ in-memory access in case that's ever wanted. Also added the
+ concept of a `destructive casereader', one that destroys cases in
+ the underlying casefile as they are read out.
+ (macro CASES_PER_BLOCK) New macro.
+ (struct casefile) New members `value_cnt', `case_list_size',
+ `case_acct_size', `being_destroyed', `cases'. Removed `head',

+
+ We're abusing the current ASCII driver by telling it to allocate a
+ 9999-line, 9999-character page in the tests. This causes some

+ ready.
+
+ * ascii.c: (struct line) New structure.
+ (struct ascii_driver_ext) Remove `page', `page_size', `line_len',

+ * moments.c (calc_moments): Adjust calculation of kurtosis to
+ avoid subtracting huge numbers from huge numbers, on Michael
+ Kiefte's advice.
+
+Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
+
+ Rework moments routines for improved numerical stability based on
+ Michael Kiefte's advice. Any bugs or remaining numerical problems
+ are still mine though.
+
+ There is now a struct moments1 for use with one-pass moments. It
+ uses a provisional means algorithm as an attempt to improve
+ accuracy of higher moments. The older struct moments now only
+ handles two-pass moments.
+
+ * aggregate.c: Use moments1 instead moments.
+
+ * descript.c: Revert previous change, which is no longer needed
+ due to the moments revision.
+
+ * moments.c: (calc_moments) New function for calculating variance,
+ skewness, kurtosis.
+ (moments_pass_one) Only accumulate weights bigger than zero.

+
+ * descript.c (calc_descriptives): Fix assert failure when only
+ MOMENT_MEAN is needed.
+
+2004-04-09 Michael Kiefte <mkiefte@dal.ca>
+
+ * descript.c:
+
+ fixed problem with parsing in match_statistic() causing
+ "DESCRIPTIVE STAT=MEAN." to barf.
+
+ "MEAN" is now default if "SORT" given without specification.
+
+ Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
+ generally less forgiving of syntax errors: better to have it do
+ nothing and type it in again then to not know what it actually did
+ instead.
+
+ z-score transformation now checks score for user-missing values
+ and checks std_dev for SYSMIS.
+
+2004-04-06 Michael Kiefte <mkiefte@dal.ca>
+
+ * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:
+ Changed dict_get_case_weight() to accept an additional int * flag
+ to complain about system-missing, user-missing, zero, or negative
+ weights and updated existing functions to pass int * to
+ dict_get_case_weight().
+
+2004-04-05 jmd <jmd@gnu.org>

+ open_active_file()/close_active_file() pairing, so introduce new

+ environment variables if other methods are not available.
+
+ glob.c: Removed a lot of global variables from glob.c and encapsulated
+ them in set.q
+
+ random.c: Tidied up the way the random seed is set.
+
+ str.c: Added a ds_vprintf function.
+
+ error.c: Extended dump_message so that messages are always broken at

+ Start working on a new output driver system, one that doesn't suck
+ so much, by adding a "device-independent" output driver. The idea
+ is to write out only a single output stream, then use separate
+ processes to translate them into whatever formats we want. This
+ is similar to how "groff" works with its various output drivers
+ (grops, grotty, grodvi, ...).
