+
+ When the lexer sees something like `-5' in the input, it has to
+ decide whether it's a negative numeric constant token or a '-'
+ token followed by a positive numeric constant token. It always
+ decides on the former, and then the parser can call
+ lex_negative_to_dash() if it wants the latter. However, this
+ doesn't work for the case of `-0', because negative zero is
+ (portably) indistinguishable from positive zero. So now we divide
+ T_NUM into two tokens, T_POS_NUM and T_NEG_NUM, to make the
+ distinction clear. This requires a little bit of extra effort,
+ because there were several references to T_NUM in the code base.
+
+ * lexer.c: (lex_get) Use T_NEG_NUM and T_POS_NUM to distinguish

+Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
+
+ Decided that case_serialize() and case_unserialize() were too
+ abstract. Also we need a couple more functions to avoid excessive
+ copying for data in/out fast paths.
+
+ * case.c: (case_serial_size) Removed.
+ (case_serialize) Rename case_to_values() and make its argument
+ explicitly an array of union values.
+ (case_unserialize) Rename case_from_values() and make its argument
+ explicitly an array of union values.
+ (case_data_all) New function.
+ (case_data_all_rw) New function.
+
+ * casefile.c: (struct casefile) Change buffer from array of
+ unsigned char to array of union value for better accuracy.
+ Redefine buffer_used and buffer_size in terms of values, not
+ bytes. Remove case_size because it is now redundant with
+ value_cnt. Fix up all references to these members.
+
+Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
+
+ * barchart.c: (struct subcat) Make `label' member const to silence

+
+ * cartesian.c: (struct dataset) Ditto.

+
+Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
+
+ Instead of providing a system or portable file writer with a raw
+ case in the format needed for output, provide it with a regular
+ case. The writer takes care of any needed translation.
+
+ * aggregate.c: Adopt new scheme for AGGREGATE.
+ (struct agr_proc) sfm_agr_case member removed.
+ (write_case_to_sfm) Removed because the new interface is easier to

+
+ * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
+
+ * pfm-write.c: Implement new scheme.
+
+ * sfm-write.c: Ditto.
+
+Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
+
+ Instead of treating `struct file_handle' as a class to subclass
+ into data files, system files, and portable files, instead use it
+ as a helper that coordinates access. Now it is opaque, too.
+
+ This means that most references to a struct file_handle are now
+ changed into references to one of struct dfm_reader, struct
+ dfm_writer, struct sfm_reader, struct sfm_writer, struct
+ pfm_reader, or struct pfm_writer, according to what's being read
+ or written.
+
+ Most related changes are only worth summarizing briefly.

+ Add next, open_cnt, type, open_mode, aux members.
+ (struct file_handle_list) Removed.

+ (fh_close_handle) Removed.
+ (mode_name) New function.
+ (fh_open) New function.
+ (fh_close) New function.
+ (fh_parse_file_handle) Renamed fh_parse().
+
+ * glob.c: (init_glob) Remove fh_init_files() call.

+
+ Break dictionary functions into separate header file.
+
+ * dictionary.h: New file.
+
+ * var.h: Moved dict_*() functions to dictionary.h.
+
+Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
+
+ Get rid of procedure-specific union in struct variable, using
+ instead a void * pointer and a destructor function.
+
+ Most related changes are only worth brief summaries.
+
+ * crosstabs.q: Fix includes. Use new struct var_range in lieu of
+ old p.crs member in struct variable.
+
+ * frequencies.q: Fix includes. Use new struct var_freqs in lieu
+ of old p.frq member in struct variable.
+
+ * histogram.c: (draw_histogram) Takes new freq_tab arg because
+ it's no longer possible to grab this from var->p.frq.
+
+ * piechart.c: (draw_piechart) Ditto.
+
+ * group.c: (group_proc_get) New function.
+
+ * levene.c: Use group_proc_get() in lieu of old p.grp_data member
+ in struct variable.
+
+ * oneway.q: Ditto.
+
+ * t-test.q: Ditto.
+
+ * main.c: (execute_command) Clear aux data in default_dict after

+
+ * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
+ member in struct variable.
+
+ * means.q: Get rid of integer mode, which is not included in

+
+ * var.h: (struct crosstab_proc) Removed.
+ (struct frequencies_proc) Removed.
+ (struct list_proc) Removed.
+ (struct get_proc) Removed.

+ (var_clear_aux) New function.
+ (var_dtor_free) New function.

+
+ * value-labs.c Fixed the implmentation of value_to_string, so
+ that it properly handles alpha values.
+
+ * oneway.q Changed instances where labels were being probed manually,
+ to use the canonical {var,value}_to_string functions
+
+Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
+
+ * examine.q cartesian.c chart.[ch] Added normal and detrended normal

+
+Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
+

+
+Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
+
+ * oneway.q Fixed problem where oneway wasn't dealing properly with

+
+Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
+
+ * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the

+ generated.
+
+ * val.h value-labels.[ch] var-labs.c Added v*to_string functions
+ to convert variables/values to strings.
+
+ * examine.q Added framework for the EXAMINE command.

+
+ * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL

+
+ * group.c group.h group_proc.h levene.c oneway.q t-test.q
+
+ Made the t-test more consistent
+ with the way it handles groups. That is, it now uses a hash instead
+ of an array of 2. Also, made the levene.c file independent of the
+ implementation of the t-test. So now levene should be fine for both
+ t-test and anova.
+
+ * Added an oneway.q file for one way anova
+
+Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>

+
+Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
+
+ 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.

+
+ * alloc.c: (out_of_memory) Make non-static.
+
+ * 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',

+ (casefile_to_disk) Don't call call_posix_fadvise. Rewritten to
+ deal with new and removed members.
+ (merge) Removed.
+ (merge_sort) Removed.
+ (casefile_sort) Removed.
+ (casefile_get_reader) Deal with new and removed members.
+ (casefile_get_destructive_reader) New function.
+ (reader_open_file) Make code more readable. Create case for
+ reader.
+ (casereader_get_casefile) New function.
+ (casereader_read) Deal with new and removed members. Now returns
+ a copy of the case, so that the caller is responsible for
+ destroying the returned case.
+ (casereader_read_xfer) New function.
+ (casereader_destroy) Destroy reader's case.
+ (test_casefile) Second arg is now a value count, all callers

+ (convert_to_double) Ditto.
+
+ * repeat.c: Remove debug code.

+
+ We're abusing the current ASCII driver by telling it to allocate a
+ 9999-line, 9999-character page in the tests. This causes some
+ systems to curl up and die because it allocates 20 MB of
+ contiguous RAM. This change alleviates at least part of the
+ problem. It is mostly a stop-gap until the new output system is
+ ready.
+
+ * ascii.c: (struct line) New structure.

+
+ * 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.

+
+ * 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:

+ weights and updated existing functions to pass int * to
+ dict_get_case_weight().
+

+
+ * vfm.c: Had to get last call to multipass_split_output() inside
+ open_active_file()/close_active_file() pairing, so introduce new
+ function.

+
+Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
+
+ Changed DFM from open-at-first-access to explicit-open. Before,
+ calling dfm_get_record() or dfm_put_record() would automatically
+ open the file. Now, you have to call dfm_open_for_reading() or
+ dfm_open_for_writing() explicitly. This makes it possible to
+ check permissions, file existence, etc. earlier.
+
+ Also made struct file_handle more opaque, and clean up in general.
+
+ * data-list.c: (cmd_data_list) Open handle for reading.
+
+ * dfm.c: (struct dfm_fhuser_ext) Add `where', `saw_begin_data'
+ members.
+ (open_file_r) Renamed dfm_open_for_reading(), rewrote.
+ (open_file_w) Renamed dfm_open_for_writing(), rewrote.
+ (open_inline_file) Removed.
+ (read_record) For inline_file, if we haven't seen BEGIN DATA, read
+ it. Deal with line_number in extension record instead of file
+ handle.
+ (dfm_get_record) Rewrote.
+ (dfm_put_record) Rewrote.
+ (dfm_push) Assert file is open and one of ours. Deal with
+ line_number in extension record instead of file handle.

+ line_number in extension record instead of file handle.
+ (cmd_begin_data) Use dfm_open_for_reading(). Mark that we saw
+ BEGIN DATA.
+
+ * file-handle.h: (enum constants RH_RF_*) Removed.
+ (enum constants FH_MD_*) Removed.
+ (struct file_handle) Removed `name', `norm_fn', `fn', `where',
+ `recform', `lrecl', `mode' members. Public references to
+ `recform' changed to use handle_get_mode(), references to `lrecl'
+ changed to use handle_get_record_width(). Added `private' member.

+
+ Fixed cmd_parse() so that it always skips past a full command
+ name. A few special commands for which this would be bad get
+ special treatment. This lets us drop code for skipping past the
+ end of a command name in most cmd_*() functions. It's not worth
+ listing all the commands affected.
+
+ * command.c: (struct command) Remove `cmd' member, replace by
+ `name' member, all references updated. Remove `word', `next',
+ `skip_entire_name' members.
+ (macro DEFCMD) Deal with revised `struct command'.
+ (macro UNIMPL) Ditto.
+ (macro SPCCMD) New macro for commands whose last word shouldn't be
+ skipped.
+ (static array cmd_table[]) Make const, rename `commands', remove
+ sentinel element.
+ (macro COMMAND_CNT) New macro.
+ (split_words) Removed.
+ (cmd_init) Removed.
+ (FILE_TYPE_okay) Make parameter const.

+ (count_matching_commands) New function.
+ (get_command_name) New function.
+ (free_words) New function.
+ (unknown_command_error) New function.
+ (figure_out_command) Renamed parse_command_name(), rewritten.
+
+ * command.def: Removed @ command. Marked BEGIN DATA, DOCUMENT,
+ FILE LABEL, REMARK, SUBTITLE, TITLE as special. Renamed EVALUATE
+ to DEBUG EVALUATE. Added N alias for N OF CASES, SORT alias for
+ SORT CASES.
+
+ * command.h: (macro SPCCMD) New.
+
+ * include.c: (cmd_include_at) Removed.
+ (cmd_include) Allow identifier to be used as filename.
+

+
+
+Sat Mar 20 13:56:00 2004 Ben Pfaff <blp@gnu.org>
+
+ Start work on better test framework.
+
+ * Makefile.am: (pspp_sources) Add debug.c.
+
+ * debug.c: New file.
+
