3 * ascii.c cartesian.c casefile.c chart.h devind.c
4 examine.q frequencies.q
5 html.c output.h piechart.c plot-chart.c plot-hist.c
7 Integrated the chart rendering into the output stream
8 (currently only works for html).
10 Removed gratuitous use of ifndef NO_CHARTS, and replaced with
11 dummy-chart.c for compiling without charts.
13 * mkfile.[ch] Created.
15 * som.[ch] tab.[ch]: Changed name of som_table to som_entity
16 Added type element so we can tell if it's a chart or a table.
18 * chart.h examine.q piechart.c plot-chart.c plot-hist.c: changed the
19 API of charts to be more like that of tables.
21 Thu Jan 13 21:00:02 WST 2005 John Darrington <john@darrington.wattle.id.au>
23 * casefile.c main.c: Moved the SIGINT handler from casefile.c to

41 (merge_once) Fix plenty of stupid mistakes.
43 Sat Jan 8 23:55:27 2005 Ben Pfaff <blp@gnu.org>
45 * casefile.c: (casefile_sleep) Need to flush_buffer() after
46 calling casefile_to_disk() or we will lose the last block in the
47 file if the casefile started out as disk-based.
48 (casefile_get_reader) Initialize reader->destructive to 0.
49 (cmd_debug_casefile) Add new test pattern.
50 (test_casefile) Define new test pattern to make sure
51 casefile_sleep() works properly.
53 Fri Jan 7 08:00:05 WST 2005 John Darrington <john@darrington.wattle.id.au>
55 * Makefile.am chart.[ch] histogram.[ch] piechart.c (Modified);
56 plot-hist.c plot-chart.c (Added) Reorganised these files in an
57 attempt to seperate the creation and processing of charts from their
60 * examine.q frequencies.q generated charts conditional upon the NO_CHARTS
63 Thu Jan 6 18:48:58 WST 2005 John Darrington <john@darrington.wattle.id.au>

67 * sort.c Somewhat more robust fix to the previous entry.
69 Wed Jan 5 21:23:31 2005 Ben Pfaff <blp@gnu.org>
71 * sort.c: (merge) Fix assertion for proper Huffman merge pattern:
72 0 == 1 modulo 1. See Knuth 5.4.9 (vol. 3, 2nd ed.,
73 pp. 361). Thanks to John Darrington <john@cellform.com.au> for
76 Wed Jan 5 22:42:26 WST 2005 John Darrington <john@darrington.wattle.id.au>
78 * case.h Fixed bug # 11307
80 Wed Jan 5 08:30:48 WST 2005 John Darrington <john@darrington.wattle.id.au>
82 * val-labs.c Fixed bug which caused a crash if VALUE LABELS had
85 Mon Jan 3 17:44:37 2005 Ben Pfaff <blp@gnu.org>
87 * pfm-read.c: (read_variables) Remove direct manipulation of
88 v->aux, which is no longer needed. Fixes Bug #11483.
90 Sat Jan 1 19:01:16 WST 2005 John Darrington <john@darrington.wattle.id.au>
92 * data-list.c Fixed a bug in parsing delimiters.
94 * group.c vars-atr.c Fixed buglet in hash/compare functions for alpha
97 * percentiles.c Properly handled calculation of Tukey hinges where
98 the number of data is small.
100 * oneway.q Used the generic value_to_string function for independent
101 variable instead of trying to do it ourselves.
103 * box-whisker.c Fixed a buglet which caused a crash if the number of
107 Fri Dec 31 16:47:45 WST 2004 John Darrington <john@darrington.wattle.id.au>
109 * examine.q box-whisker.c chart.h Implemented boxplots in EXAMINE
111 * percentiles.c Fixed some bugs when calculating percentiles when
112 there's a small number of cases.
114 Wed Dec 29 08:18:08 WST 2004 John Darrington <john@darrington.wattle.id.au>
116 * percentiles.[ch] Added. Calculates percentiles and Tukey hinges

120 Fri Dec 24 15:09:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
122 * t-test.q Fixed bug #11227 Made t-test work when the independent
125 Sat Dec 11 11:43:45 WST 2004 John Darrington <john@darrington.wattle.id.au>
127 * factor_stats.c Fixed calculation of trimmed mean under various
130 Sat Dec 4 17:14:45 WST 2004 John Darrington <john@darrington.wattle.id.au>
132 * histogram.c chart.[ch] factor_stats.c frequencies.q
134 Added code to calculate sensible histogram ranges and limits.
136 Thu Dec 2 13:37:43 WST 2004 John Darrington <john@darrington.wattle.id.au>
138 * chart.h Updated to reflect many API changes.
140 * cartesian.c chart.c Moved the definitions of chart_write_{xy}scale from
141 cartesian.c and into chart.c
143 * factorstats.[ch] Added the histogram calculations
145 * casefile.c Removed an unused variable.
147 * frequencies.q examine.q histogram.c Reworked the API for
150 * piechart.c Revised the API for piecharts.
152 * var.h Moved the definitions of freq_tab and freq out of var.h
153 and into frequencies.q where they belong.
155 Tue Nov 30 21:10:20 2004 Ben Pfaff <blp@gnu.org>
157 * flip.c: (flip_file) Check for off_t separately from fseeko(),
160 Tue Nov 30 08:47:41 2004 Ben Pfaff <blp@gnu.org>
162 * flip.c: (flip_file) If fseeko() is not available, use long int
163 for off_t. Thanks to "Marshall DeBerry" <mdb@radix.net> for
164 reporting the problem.
166 Mon Nov 29 12:20:59 WST 2004 John Darrington <john@darrington.wattle.id.au>
168 * examine.q factor_stats.[ch] Changed stderr to se_mean to avoid
171 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
173 * var-labs.c (var_to_string) Now returns null if the variable is null
175 * value-labels.c (value_to_string) Made it return null if either the
176 value or the variable is null.
178 * hash.c (hsh_clear) Fixed a buglet.
180 * examine.q factor_stats.[ch] Largely rewrote, because I'd started
181 with the wrong model.
183 * casefile.[ch] Added a function to return the casereader.case_idx
186 * examine.q Implemented the extreme values results.
188 John Darrington <john@darrington.wattle.id.au>
190 * settings.h set.c glob.[ch] frequencies.q q2c.c error.c lexer.[ch]
191 output.[ch] getline.c
193 Plugged some memory leaks
195 Mon Nov 15 23:47:40 2004 Ben Pfaff <blp@gnu.org>
197 Adopt GSL random number generators, paving the way for providing
198 the complete suite of random number generators on expressions.
200 * Makefile.am: Remove random.c, random.h.
206 * algorithm.c: (algo_default_random) Use GSL functions.
208 * casefile.c: (test_casefile) Use GSL RNG functions.
210 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
213 * sample.c: (cmd_sample) Use GSL RNG functions.
214 (sample_trns_proc) Ditto.
216 * set.q: (static var set_seed) Removed.
217 (static var seed_flag) Removed.
218 (static var rng) New variable.
219 (aux_stc_custom_seed) No seed value anymore, don't print anything.
220 (stc_custom_seed) Use new seed functions.
221 (seed_is_set) Removed.
222 (get_rng) New function that composes the entire external
224 (set_rng) New function.
225 (random_seed) New function.
227 Mon Nov 15 22:08:25 2004 Ben Pfaff <blp@gnu.org>
229 * expr-evl.c: (expr_evaluate) Fix XDATE.JDAY formula. Thanks to
230 John Darrington <john@darrington.wattle.id.au> for reporting this
233 Tue Nov 16 13:19:18 WST 2004 John Darrington <john@darrington.wattle.id.au>
235 * permissions.c command.def Added the PERMISSIONS command
237 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
239 * q2c.c: (dump_header) Don't try to emit #includes at very top of
240 output file because that will precede #include <config.h>, which
242 (main) Add needed headers to /* (header) */ code.
244 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
246 Instead of making system or portable file readers responsible for
247 dropping and reordering variables, make them read full cases and
248 let the caller take care of any changes.
250 * get.c: New "case map" structure to handle this. Use for GET,
251 IMPORT, MATCH FILES. Essentially rewrite the whole file.
253 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
254 changed appropriately.
256 * sfm-read.c: (sfm_read_case) Ditto.
258 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
260 Decided that case_serialize() and case_unserialize() were too
261 abstract. Also we need a couple more functions to avoid excessive
262 copying for data in/out fast paths.
264 * case.c: (case_serial_size) Removed.
265 (case_serialize) Rename case_to_values() and make its argument
266 explicitly an array of union values.
267 (case_unserialize) Rename case_from_values() and make its argument
268 explicitly an array of union values.
269 (case_data_all) New function.
270 (case_data_all_rw) New function.
272 * casefile.c: (struct casefile) Change buffer from array of
273 unsigned char to array of union value for better accuracy.
274 Redefine buffer_used and buffer_size in terms of values, not
275 bytes. Remove case_size because it is now redundant with
276 value_cnt. Fix up all references to these members.
278 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
280 * barchart.c: (struct subcat) Make `label' member const to silence
281 GCC warning with -Wwrite-strings.
283 * cartesian.c: (struct dataset) Ditto.
285 * case.c: Don't re-define NDEBUG if already defined.
286 Add lots of comments.
288 * str.c: Fix includes.
290 * crosstabs.q: Fix includes.
292 * examine.q: Fix includes. Fix GCC warning about unused
295 * frequencies.q: (stat macro) Removed and replaced where used by
298 * list.q: Fix includes.
300 * oneway.q: Fix includes.
302 * piechart.c: Fix includes. Only define M_PI if not already
305 * sfm-read.c: (bswap) New function.
306 (bswap_int32) Write in terms of bswap.
309 * str.c: (ds_data) Add external definition here, needed because
310 str.h has only an `extern inline' version.
312 * value-labels.c: Fix includes.
314 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
316 Instead of providing a system or portable file writer with a raw
317 case in the format needed for output, provide it with a regular
318 case. The writer takes care of any needed translation.
320 * aggregate.c: Adopt new scheme for AGGREGATE.
321 (struct agr_proc) sfm_agr_case member removed.
322 (write_case_to_sfm) Removed because the new interface is easier to
325 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
327 * pfm-write.c: Implement new scheme.
329 * sfm-write.c: Ditto.
331 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
333 Instead of treating `struct file_handle' as a class to subclass
334 into data files, system files, and portable files, instead use it
335 as a helper that coordinates access. Now it is opaque, too.
337 This means that most references to a struct file_handle are now
338 changed into references to one of struct dfm_reader, struct
339 dfm_writer, struct sfm_reader, struct sfm_writer, struct
340 pfm_reader, or struct pfm_writer, according to what's being read
343 Most related changes are only worth summarizing briefly.
345 * dictionary.c: (dict_clear) Destroy aux data in deleted
347 (dict_clear_aux) New function.
348 (dict_create_var) Initialize aux, aux_dtor.
349 (dict_delete_var) Destroy aux data in deleted variable.
351 * file-handle.h: (struct fh_ext_class) Removed.
352 (struct file_handle) Removed.
353 (fh_init_files) Removed.
355 * file-handle.q: Changed references to a handle's `private' member
356 to direct references.
357 (struct private_file_handle) Renamed file_handle.
358 Add next, open_cnt, type, open_mode, aux members.
359 (struct file_handle_list) Removed.
360 (extern var inline_file) Removed.
361 (static var file_handles) Changed from file_handle_list * to
363 (create_file_handle) Initialize new members.
364 (fh_close_handle) Removed.
365 (mode_name) New function.
366 (fh_open) New function.
367 (fh_close) New function.
368 (fh_parse_file_handle) Renamed fh_parse().
370 * glob.c: (init_glob) Remove fh_init_files() call.
372 * aggregate.c: use sfm_writer.
373 (create_sysfile) Removed because the new interface is simpler.
375 * apply-dict.c: Use sfm_reader.
377 * data-list.c: Use dfm_reader.
379 * file-type.c: Use dfm_reader.
381 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
383 * inpt-pgm.c: Use dfm_reader.
385 * print.c: Use dfm_writer.
387 * sysfile-info: Use sfm_reader.
389 * dfm-read.c: Adopt new file handle infrastructure.
391 * dfm-write.c: Ditto.
395 * pfm-write.c: Ditto.
399 * sfm-write.c: Ditto.
401 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
403 Break dictionary functions into separate header file.
405 * dictionary.h: New file.
407 * var.h: Moved dict_*() functions to dictionary.h.
409 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
411 Get rid of procedure-specific union in struct variable, using
412 instead a void * pointer and a destructor function.
414 Most related changes are only worth brief summaries.
416 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
417 old p.crs member in struct variable.
419 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
420 of old p.frq member in struct variable.
422 * histogram.c: (draw_histogram) Takes new freq_tab arg because
423 it's no longer possible to grab this from var->p.frq.
425 * piechart.c: (draw_piechart) Ditto.
427 * group.c: (group_proc_get) New function.
429 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
436 * main.c: (execute_command) Clear aux data in default_dict after
437 each command. (It's debatable whether this should be done.)
439 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
440 member in struct variable.
442 * means.q: Get rid of integer mode, which is not included in
443 recent SPSS and was the only code that wanted per-variable private
446 * var.h: (struct crosstab_proc) Removed.
447 (struct frequencies_proc) Removed.
448 (struct list_proc) Removed.
449 (struct get_proc) Removed.
450 (struct means_proc) Removed.
451 (struct matrix_data_proc) Removed.
452 (struct match_files_proc) Removed.
453 (lots of enums) Removed.
454 (struct variable) Removed members `p', `get'. Add member
457 * vars-atr.c: (var_attach_aux) New function.
458 (var_detach_aux) New function.
459 (var_clear_aux) New function.
460 (var_dtor_free) New function.
461 (discard_variables) Use NULL instead of inline_file.
463 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
465 * value-labs.c Fixed the implmentation of value_to_string, so
466 that it properly handles alpha values.
468 * oneway.q Changed instances where labels were being probed manually,
469 to use the canonical {var,value}_to_string functions
471 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
473 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
474 plots. Changed the API of the cartesian plot to be a much lower level
477 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
479 * examine.q Added some of the parametric calculations
481 * factor_stats.[ch] Created
483 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
485 * examine.q Changed the definition of factors to be a composite, and
486 dealt with the consequences.
488 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
490 * examine.q Fixed problem where examine wasn't dealing properly with
493 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
495 * oneway.q Fixed problem where oneway wasn't dealing properly with
498 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
500 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
501 command which had settings didn't get the appropriate code
504 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
505 to convert variables/values to strings.
507 * examine.q Added framework for the EXAMINE command.
509 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
511 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
512 subcommand types. Changed frequencies.q to use it rather then the
513 custom parser. Dealt with the consequences. Added a test for NTILES
514 subcommand of frequencies.
516 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
518 * oneway.q Fixed up the behaviour when given missing values
520 * levene.c oneway.q Fixed a buglet with the levene statistic and
521 incorporated the levene test into the oneway command.
523 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
524 global scope, since they're only relevant to T-TEST
526 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
528 * group.c group.h group_proc.h levene.c oneway.q t-test.q
530 Made the t-test more consistent
531 with the way it handles groups. That is, it now uses a hash instead
532 of an array of 2. Also, made the levene.c file independent of the
533 implementation of the t-test. So now levene should be fine for both
536 * Added an oneway.q file for one way anova
538 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
540 * descript.c: (cmd_descriptives) Remove harmless but bogus test in
543 Mon May 31 20:45:24 2004 Ben Pfaff <blp@gnu.org>
547 * data-list.c: (cmd_data_list) Free dls->delims on lossage.
548 (data_list_trns_free) Free dls->delims.
550 * t-test.q: (tts_custom_pairs) Free vars.
551 (ssbox_one_sample_init) Fix tab_vline() argument.
552 (ssbox_independent_samples_init) Ditto.
553 (trbox_paired_init) Ditto.
554 (trbox_one_sample_init) Ditto.
556 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
558 Generalize casefiles to the extent that we can use them for
559 sorting and other kinds of data transformations. Change cases to
560 be copy-on-write to improve memory efficiency in common cases.
561 Every access to a member of a `struct ccase' was changed to be a
562 call to a case_*() function, especially case_data(), case_num(),
563 case_str(), or case_data_rw(). Many instances of a local variable
564 named "case_num" were changed to "case_idx" as a consequence.
565 Many `struct ccase *' were changed to actual `struct ccase'
566 because of copying semantics of cases. In several places there
567 was a choice between updating debug code to work with the new ADTs
568 or just deleting it because it was useless; I chose to delete it.
570 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
576 * aggregate.c: (struct agr_proc) Change type of `sort' to
577 sort_criteria *. Add `break_vars', `break_var_cnt' members.
578 Rename `vars' to `agr_vars', all references updated. Change
579 `agr_case' to type `struct ccase'.
580 (cmd_aggregate) Deal with new members. Use case_create(),
581 sort_active_file_in_place(), sort_active_file_to_casefile().
582 (agr_destroy) Deal with new members.
583 (aggregate_single_case) Ditto.
584 (dump_aggregate_info) Ditto.
585 (initialize_aggregate_info) Ditto.
586 (agr_to_active_file) Ditto.
587 (presorted_agr_to_sysfile) Ditto.
588 (sort_agr_to_sysfile) Removed.
590 * alloc.c: (out_of_memory) Make non-static.
592 * alloc.h: Prototype out_of_memory().
594 * casefile.c: Switched from a linked list in-memory representation
595 to a two-level array-style representation. The linked list was
596 appropriate when we could stick a header onto cases, but that's no
597 longer the case. Also, the two-level array will allow for random
598 in-memory access in case that's ever wanted. Also added the
599 concept of a `destructive casereader', one that destroys cases in
600 the underlying casefile as they are read out.
601 (macro CASES_PER_BLOCK) New macro.
602 (struct casefile) New members `value_cnt', `case_list_size',
603 `case_acct_size', `being_destroyed', `cases'. Removed `head',
605 (struct casereader) Removed `cur'. Added `destructive', `c'.
606 (global var casefiles) Made static.
607 (static var case_bytes) New var.
608 (casefile_create) Takes a value count, not a case size in bytes,
609 to conform to the case interface. All callers updated. Deal with
610 new and removed members.
611 (casefile_destroy) Deal with new and removed members.
612 (casefile_sleep) New function.
613 (casefile_get_case_size) Removed.
614 (casefile_get_value_cnt) New function.
615 (casefile_append) Rewritten to deal with new and removed members.
616 (casefile_append_xfer) New function.
617 (write_case_to_disk) Use case_serialize().
618 (call_posix_fadvise) Removed because posix_fadvise64 segfaults.
619 Couldn't figure out why.

917 (reader_open_file) Ditto.

958 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
960 We're abusing the current ASCII driver by telling it to allocate a
961 9999-line, 9999-character page in the tests. This causes some
962 systems to curl up and die because it allocates 20 MB of
963 contiguous RAM. This change alleviates at least part of the
964 problem. It is mostly a stop-gap until the new output system is
967 * ascii.c: (struct line) New structure.
968 (struct ascii_driver_ext) Remove `page', `page_size', `line_len',

988 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>

1007 Rework moments routines for improved numerical stability based on
1008 Michael Kiefte's advice. Any bugs or remaining numerical problems
1009 are still mine though.
1011 There is now a struct moments1 for use with one-pass moments. It
1012 uses a provisional means algorithm as an attempt to improve
1013 accuracy of higher moments. The older struct moments now only
1014 handles two-pass moments.
1016 * aggregate.c: Use moments1 instead moments.
1018 * descript.c: Revert previous change, which is no longer needed
1019 due to the moments revision.

1023 (moments_pass_one) Only accumulate weights bigger than zero.
1024 (moments_calculate) Allow calculating the mean on pass one, others

1026 (struct moments1) New structure.
1027 (init_moments1) New function.
1028 (moments1_clear) Ditto.
1029 (moments1_create) Ditto.

1045 MOMENT_MEAN is needed.
1047 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
1051 fixed problem with parsing in match_statistic() causing
1052 "DESCRIPTIVE STAT=MEAN." to barf.
1054 "MEAN" is now default if "SORT" given without specification.
1056 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
1057 generally less forgiving of syntax errors: better to have it do
1058 nothing and type it in again then to not know what it actually did
1061 z-score transformation now checks score for user-missing values
1062 and checks std_dev for SYSMIS.
1064 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
1066 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:
1067 Changed dict_get_case_weight() to accept an additional int * flag
1068 to complain about system-missing, user-missing, zero, or negative
1069 weights and updated existing functions to pass int * to
1070 dict_get_case_weight().

1103 * q2c.c: Added an implicit /ALGORITHM subcommand to everything.
1105 Fri Apr 2 11:25:22 WAST 2004 John Darrington <john@darrington.wattle.id.au>
1107 * t-test.q, levene.c, levene.h Converted t-test (incl levene) to
1108 use the new multipass_split_... mechanism.

1112 * frequencies.q: (calc_stats) Use moments data structure and
1113 calc_seskew(), calc_sekurt() functions.
1115 * set.q main.c settings.h Added support for --syntax and --algorithm
1118 Tue Mar 30 22:04:19 2004 Ben Pfaff <blp@gnu.org>
1120 * vfm.c: Had to get last call to multipass_split_output() inside
1121 open_active_file()/close_active_file() pairing, so introduce new
1123 (internal_procedure) Move procedure() code here, except for calls
1124 to open_active_file() and close_active_file().

1144 (expensive_assert) New macro which expands to assert if
1145 EXTRA_CHECKS is defined, to nothing otherwise.
1146 (unique) Use expensive_assert().
1147 (binary_search) Ditto.
1153 * command.c: (conflicting_3char_prefixes) Words that are the same
1154 don't cause conflicts when they are abbreviated to the first three
1157 * expr-evl.c: (CONCAT_func) Fix memory leak by incrementing struct
1158 nonterm_node's n earlier.

1496 Changed DFM from open-at-first-access to explicit-open. Before,
1497 calling dfm_get_record() or dfm_put_record() would automatically
1498 open the file. Now, you have to call dfm_open_for_reading() or

1616 Fixed cmd_parse() so that it always skips past a full command
1617 name. A few special commands for which this would be bad get
1618 special treatment. This lets us drop code for skipping past the
1619 end of a command name in most cmd_*() functions. It's not worth
1620 listing all the commands affected.
1622 * command.c: (struct command) Remove `cmd' member, replace by
1623 `name' member, all references updated. Remove `word', `next',
1624 `skip_entire_name' members.

1680 * set.q: Implemented the SHOW command, and synced it to the existing
1683 Added a handler for SIGWINCH so that viewlength and viewwidth follow
1684 changes as the window size is changed.
1686 Added fallback to set viewlength and viewwidth from LINES and COLUMS
1687 environment variables if other methods are not available.
1689 glob.c: Removed a lot of global variables from glob.c and encapsulated
1692 random.c: Tidied up the way the random seed is set.
1694 str.c: Added a ds_vprintf function.

2834 `read' function to take a write_case_func and a write_case_data.
2835 Also updated every caller of write_case() to instead call them
2836 through these arguments. In some cases this meant that the extra
2837 args had to be threaded through a couple of extra levels. This
2838 wasn't difficult or interesting so the details won't be given.
2840 * data-list.c: (struct repeating_data_trns) Add members
2841 `write_case', `wc_data' as kluge.
2842 (read_one_set_of_repetitions) Rename repeating_data_trns_proc and

2846 * data-list.h: New file to declare repeating_data_trns_proc() and
2847 repeating_data_set_write_case().
2849 * inpt-pgm.c: (input_program_source_read) Call
2850 repeating_data_set_write_case() for all the REPEATING DATA
2851 transformations, so that they know where to send their cases.
2852 It's a big kluge. Also kluge in END CASE.
2853 (end_case_trns_proc) Never called anymore, but we still need it,
2856 * sort.c: (read_sort_output) Update to match struct case_stream

2890 * Change unused to UNUSED in many source files to reflect modified
2891 pref.h. Change use of __WIN32__, __MSDOS, __DJGPP__,
2892 __CYGWIN32__, __unix__, and unix not to assume that they're
2893 defined to a nonzero value. Change use of __attribute__ to use
2894 NO_RETURN or PRINTF_FORMAT instead.
2896 * alloc.h: Move definitions for local_alloc(), local_free() here
2897 from ../pref.h.orig and simplify.
2899 * expr-evl.c: Instead of working differently based on PAGED_STACK,

2981 Start working on a new output driver system, one that doesn't suck
2982 so much, by adding a "device-independent" output driver. The idea
2983 is to write out only a single output stream, then use separate
2984 processes to translate them into whatever formats we want. This
2985 is similar to how "groff" works with its various output drivers
2986 (grops, grotty, grodvi, ...).

3369 (dict_get_split_cnt) New function, replaces reading
3371 (dict_set_split_vars) New function, replaces writing dict->splits.
3372 (dict_get_label) New function, replaces reading dict->label.
3373 (dict_set_label) New function, replaces writing dict->label.
3374 (dict_get_documents) New function, replaces reading
3376 (dict_set_documents) New function, replaces writing
3379 All references to above functions updated.
3381 * aggregate.c: (cmd_aggregate) Copy file label and documents from
3382 old dictionary to new by hand, because dict_create() can't do it
3383 itself. Use dict_set_documents(), dict_set_split_vars().
3385 * temporary.c: (cancel_temporary) Also set temp_dict to NULL after
3386 calling dict_destroy().
3388 * data-list.c: (dls_var_spec) Remove `type' member, replace by
3390 (fixed_parse_compatible) Some slightly nontrivial changes for
3392 (dump_fmt_list) Ditto.
3395 * file-type.c: (create_col_var) Ditto.
3397 * get.c: (cmd_get) Use dict_compact_values() instead of a loop.

3416 there's no need for that by hand.

3419 earlier, so that we can do the compaction as a single step using
3420 dict_compact_values(). Use dict_clear_vectors().

3437 * aggregate.c: Eliminate separation of weighted and unweighted
3438 case. It made the code too obscure and I doubt it was actually
3439 faster. Instead, all code uses the "weighted" code, because
3440 that's a generalization of the "unweighted" code.
3443 (parse_aggregate_functions) No need to set FWEIGHT.
3444 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
3445 (dump_aggregate_info) Ditto.

3995 `table' to `entries'. Removed `mp'. All references updated.
3996 (hsh_clear) Don't shrink entries array; if the hash was this big

3999 (force_hsh_insert) Renamed hsh_force_insert.
4000 (force_hsh_find) Renamed hsh_force_find.

4021 functions than the ones we had, and cleaned up the names to boot:
4023 * hash.c: (hashpjw_d) Removed.

4035 * hash.c: (hsh_foreach) Removed. All references updated to use
4036 hsh_first/hsh_next instead.
4037 (hsh_first) New function. Notably, unlike hsh_foreach() it does
4038 not treat a null pointer as an empty hash table.
4039 (hsh_next) New function.
4041 Made deletion possible, though slow:
4043 * hash.c: (locate_matching_entry) New function.
4044 (hsh_find) Use locate_matching_entry().
4045 (hsh_delete) New function also using locate_matching_entry().
4046 (hsh_force_delete) New function.

4054 * Makefile.am: Add quicksort.c, quicksort.h.
4056 Fri Dec 12 13:31:58 2003 Ben Pfaff <blp@gnu.org>

4727 Using alphanumeric variables in functions under AGGREGATE
4728 segfaulted. Fixed. Thanks to Dr. Dirk Melcher
4729 <BZN-mdksh@t-online.de> for reporting this bug.
4731 * aggregate.c: (parse_aggregate_functions) When setting the
4732 FSTRING bit, also allocate memory for the `string' member of
4734 (free_aggregate_functions) Free iter->string. Don't use the
4735 non-function bits when indexing the array of functions.
4736 [DEBUGGING] (debug_print) Don't use the non-function bits when
4737 indexing the array of functions.
4739 Sun May 30 00:00:54 1999 Ben Pfaff <blp@gnu.org>
4741 Under certain circumstances, the final case would be omitted from
4742 the results of an AGGREGATE operation. Fixed. Thanks to Dr. Dirk
4743 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4745 * aggregate.c (agr_00x_end_func): Increment number of cases in
4746 sink before writing case. For streams that keep track of how many
4747 cases there are based on this value, this means that the last case
4748 will be read in on the next stream read.
4750 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
4752 Undefined behavior was invoked by referencing a freed pointer.
4754 * vfm.c (memory_stream_write): Free pointer *after* checking for

4769 * sort.c: (allocate_cases) Initialize i.
4771 Sat May 29 21:40:54 1999 Ben Pfaff <blp@gnu.org>
4773 Syntax errors in function descriptions on AGGREGATE caused core
4776 * aggregate.c (cmd_aggregate): Don't free agr_dict after calling
4777 free_aggregate_functions(), since that function already frees
4780 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
4782 A null pointer was dereferenced, causing a core dump, when
4783 PERCENTILES was specified on FREQUENCIES. This fixes the problem,
4784 but PSPP still doesn't calculate percentiles. Thanks to Regnor
4785 Jernsletten <rjernsle@eunet.no> for reporting this problem.
4787 * arena.c: (arena_malloc) If the arena hasn't been initialized
4788 already, initialize it.
4790 Sat May 29 20:47:29 1999 Ben Pfaff <blp@gnu.org>
4792 * Makefile.cygwin: New file supplied by Hankin <hankin@dunno.com>

4796 Sat May 29 20:36:04 1999 Ben Pfaff <blp@gnu.org>
4798 SORT always sorted in ascending order. Fixed. Thanks to Dr. Dirk

4805 Tue Mar 9 13:18:54 1999 Ben Pfaff <blp@gnu.org>
4807 SPLIT FILE with a string variable caused a core dump. Fixed.
4809 * vfm.c: If the variable is a string then make a temporary value
4810 struct pointing to it. The underlying problem is a lot bigger
4811 than this (see TODO) but this is a stopgap for the simple case at
4814 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
4816 Nested INCLUDEs didn't work. Fixed.
4818 * getline.c: (getl_include) Set first_line to NULL in allocated
4821 Tue Mar 9 13:13:46 1999 Ben Pfaff <blp@gnu.org>
4823 The MATCH FILES procedure set the values of variables not present
4824 to 0. It should have been SYSMIS. This is now fixed.
4826 * get.c: (mtf_delete_file_in_place) Replace 0.0 by SYSMIS.
4828 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>
4830 The REMARK command was too aggressive about skipping lines. It
4831 didn't like being the last command in a file.
4833 * command.c: (cmd_remark) Call get_entire_line() instead of
4836 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
4838 Comment parsing wasn't consistent with the rest of the code in its
4839 idea of where one command ends and another starts. This meant
4840 that sometimes commands would be mysteriously ignored. Thanks to
4841 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4843 * command.c: (parse_cmd) Hand off comment parsing to new function
4844 skip_comment() in lexer.c.
4845 * lexer.c: (skip_comment) New function.
4847 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
4849 The TABLE subcommand on MATCH FILES worked only erratically at
4850 best. This fixes it. Thanks to Dr. Dirk Melcher
4851 <BZN-mdksh@t-online.de> for reporting this bug.
4853 * get.c: (mtf_compare_BY_values) When comparing string values, a
4854 difference of 1 is still a difference :-)
4855 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
4856 advance TABLE files automatically when matched. Comment fixes.
4858 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>
4860 VARIABLE LABELS rejected a slash before the first variable
4861 specification, contradicting the documentation. Thanks to Walter
4862 M. Gray <graywm@northernc.on.ca> for reporting this bug.
4864 * var-labs.c: (cmd_variable_labels) Ignore a leading slash in
4865 command specification.
4867 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>
4869 Because of an incorrect optimization in memory allocation,
4870 CROSSTABS sometimes segfaulted when asked to output multiple
4871 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4874 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
4875 are passed to output_pivot_table() for its use.
4876 (output_pivot_table) Instead of assuming the number of columns is
4877 constant, keep track with maxcols. In general mode, use maxcells
4878 to determine whether more matrix cells need to be allocated.
4880 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
4882 CROSSTABS didn't display value labels for column and row
4883 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4886 * crosstabs.q: (table_value_missing) If the specified value has a
4887 value label for this variable, then show it instead of the raw
4889 (display_dimensions) Delegate display of value_labels to
4890 table_value_missing.
4892 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
4894 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
4895 <BZN-mdksh@t-online.de> for reporting this bug.
4897 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
4898 if the file isn't declared as binary.
4900 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
4902 MATCH FILES corrupted memory and dumped core on some syntax
4905 * get.c: (cmd_match_files) Set file->handle to NULL before
4907 (mtf_free_file) Don't free a null dictionary.
4909 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
4911 MATCH FILES should set numeric values not available to the
4912 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
4913 <BZN-mdksh@t-online.de> for reporting this bug.
4915 * get.c: (mtf_processing) Set unused records to system-missing,
4918 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>
4920 KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
4921 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
4923 * temporary.c: (save_dictionary) Initialize var_by_name AVL tree
4924 in newly created dictionary, and add each copied variable to the

4931 * get.c: (trim_dictionary) Free variable list for KEEP after
4934 Mon Jan 18 12:57:36 1999 Ben Pfaff <blp@gnu.org>
4936 Some systems didn't like the way open_file was coded. Thanks to
4937 Hankin <hankin@rogue.consultco.com> for pointing this out.
4939 * filename.c: (open_file) Don't try to store stdin, stdout,
4940 stderr as part of an array, because that doesn't always work.
4942 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
4944 The SAVE procedure didn't save long string variables properly.
4945 Fixed by this patch. Thanks to Hankin
4946 <hankin@rogue.consultco.com> for this patch.
4948 * sfm-write.c: (write_variable) Fix off-by-one error in writing
4949 out variable pad records.
4951 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
4953 Previously, if PRINT SPACE were given a negative argument, it
4954 would report an error, then spin in an (almost) infinite loop.
4955 This fixes that behavior.
4957 * print.c: (print_space_trns_proc) After reporting a negative
4958 argument, set number of lines to print to 1.
4960 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
4962 SPSS 8.0 outputs some new record types in its system files, and it
4963 allows longer value labels. Accept these system files.
4965 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
4966 11 emitted by SPSS 8.0.
4968 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
4970 The LIST procedure was too conservative in allocating space for
4971 buffers, which caused a bug that only showed up with very long
4972 output variables. Thanks to Hankin <hankin@dunno.com> for this
4975 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
4977 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
4979 Typo meant string format specifiers weren't checked properly. I
4980 think that Hankin <hankin@dunno.com> sent me this report, but I'm
4981 willing to be corrected on this point.
4983 * format.c: (check_string_specifier) Fix obvious typo.
4985 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>

4997 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
4998 other behavior, *sigh*. This patch hopefully fixes that. This
4999 time I've actually tested it.
5001 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
5003 * data-list.c: (read_from_data_list_free,
5004 read_from_data_list_list) Call parse_string_as_format() directly

5007 Tue Jan 5 12:31:19 1999 Ben Pfaff <blp@gnu.org>
5009 Occasionally, you may encounter a script that wants to be
5010 interpreted in interactive mode. Make -i emulate this behavior to
5011 allow such scripts to be executed with PSPP.
5013 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
5015 * cmdline.c: (pre_syntax_message[]) Update -i description.
5017 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
5018 when -i is given on the command line) don't treat unindented lines
5019 as starting a new command.
5021 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
5023 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
5024 mostly caused by local initialized aggregates. After egcs is
5025 fixed upstream these can be removed, but for now they're not a big
5028 * ascii.c: (ascii_postopen_driver) Checker chokes on local
5029 initialized arrays. Avoid this.
5031 * sfm-write.c: (sfm_write_dictionary) Don't use a local
5034 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
5036 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
5037 following changes avoid. Currently I compile sources with egcs
5038 1.1.1 and gcc 2.7.2.3 before sending them out.
5040 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.

5073 * data-in.c: Examined each of the parsing functions to make sure
5074 that they wouldn't dump core if they were passed a string of the
5075 wrong length, since now the DATA LIST FREE/LIST routines don't
5076 check for field width before passing it to the data parser.
5077 (parse_RBHEX, parse_AHEX) Reject odd length input.
5078 (parse_string_as_format) Reject input that's too short or too
5081 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad
5082 a field to its entire declared output width then pass it to the
5083 data-in parsing routines. This contradicted the documented
5084 behavior. This is fixed in these changes. Thanks to Mark H. Wood
5085 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
5086 free-format parsing that differed from SPSS.

8396 (parse_command_line) Added terminating null to end of
8397 `long_options' array definition.
8398 (pre_syntax_message) Fixes.
8399 (usage) Shows the default emulation in the syntax message by
8400 calling pick_compat().
8402 * getline.c: (getl_add_include_dir) Separates paths with
8403 PATH_DELIMITER, not DIR_SEPARATOR.

8415 * output.c: (outp_get_paper_size)
8416 s/STAT_OUTPUT_INIT_FILE/STAT_OUTPUT_PAPERSIZE_FILE/.
8418 Sun May 25 22:34:07 1997 Ben Pfaff <blp@gnu.org>
8420 * ascii.c, postscript.c, sfm-read.c, sfm-write.c, sort.c: Include
8421 <errno.h>. GNU libc 2 enforces this!
8423 * command.c: (parse_cmd) Fixed problem with `else' clause being
8424 paired with wrong `if'. Comment fix.
8426 Fri May 9 16:53:52 1997 Ben Pfaff <blp@gnu.org>
8428 * getline.c: [!HAVE_LIBREADLINE] (read_console) Changed
8429 blp_getline() to getline().
8431 * output.c: (outp_eval_dimension) Changed the fix from last time;
8432 there was no variable `a'.
8434 * q2c.c: (get_line) Fixed boundary condition overrun bug.
8436 Mon May 5 21:58:22 1997 Ben Pfaff <blp@gnu.org>

8451 * output.h: (struct outp_class_struct) Removed
8452 text_get_font_position method. All references deleted.
8454 * postscript.c: Big change here. Fontmaps were completely
8455 eliminated because of a change in philosophy. Comment fixes.
8456 (struct ps_fontmap, ps2dit_map, font_family, dit2family_map)
8458 (struct ps_driver_ext) `position', `fontmap', `prop_name',
8459 `fixed_name' members removed. New members `prop_family',
8460 `fixed_family'. `family' member changed to type char *.
8461 (static var ps_fontmaps) Removed.
8463 (ps_init_driver) Removed obsolete references, updated.
8464 Initializes `translate_x', `translate_y', `scale'. Doesn't read
8465 fontmap, of course. Refers to font names through internal_name
8466 rather than subversive means. Frees proper items.
8467 (static var option_tab[]) Removed `fontmap-file' option; renamed
8468 `fixed-font', `prop-font'.
8469 (ps_option) Corresponds to option_tab[].
8470 (read_fontmap, release_fontmap, ps_to_dit, compare_ps2dit,
8471 hash_ps2dit, compare_dit2family, hash_dit2family, compare_family,
8472 hash_family) Removed.
8473 (postopen) Generates font names from family names. Gets
8474 PostScript font name properly. New prologue file comment `!!!'
8476 (ps_open_page) Adds translate_x, translate_y to BP prologue
8477 function; gives SF argument floating-point format.
8478 (ps_text_set_font_by_name) Doesn't try to map PostScript->Groff
8479 font name. Doesn't change font family.
8480 (ps_text_set_font_by_position) Generates Groff font name from font
8481 family name instead of through table lookup.
8482 (ps_text_set_font_by_family) Renamed `ps_text_set_font_family',
8483 all references changed. Reduced to simple string assignment.
8484 (ps_get_font_name) Removed.
8485 (ps_get_font_family) Reduced to string return.
8486 (text) Doesn't save `position' since it no longer exists. Ugly
8487 kluge to save font family--fix soon?
8488 (load_font) Removed PostScript name argument.
8490 Thu May 1 14:58:59 1997 Ben Pfaff <blp@gnu.org>
8492 * postscript.c: Comment fix.

8501 * ascii.c: (delineate) Sets text size even if width is zero.
8503 * command.c: Comment fix.
8504 (static var cmd_table[]) Re-enabled EVALUATE command.
8505 (parse_cmd) Lotsa comment fixes. Fixed infinite loop in parsing
8506 of comments in script files. Now more liberal on criteria for
8507 performing a state transition--if *anything* happened correctly,
8508 not just if *everything* happened correctly.
8510 * data-out.c: (convert_F) Comment fix. Why in the fsck does
8511 Checker segfault on formatting large numbers and why in the fsck
8512 hadn't I noticed this before?
8514 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
8516 * list.q: (cmd_list) Commented out the actual output routine
8517 because of various problems. Probably will abandon the idea of
8518 using the general `crushed tables' for the LIST procedure.
8520 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
8521 clearing it. Allocates a new var_by_name dictionary before trying
8522 to add members to it.
8524 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
8525 `sib'. Changed type of `node' argument.
8526 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
8528 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
8529 [DEBUGGING] Only deletes the variable from var_by_name if that var
8532 Fri Apr 18 16:48:41 1997 Ben Pfaff <blp@gnu.org>
8534 * Makefile.am: Added include files to SOURCES. Added
8535 frequencies.q to EXTRA_DIST. Removed include/ from INCLUDES. Now
8536 includes rules for q2c. Added `boast' target.
8538 Fri Apr 18 15:42:22 1997 Ben Pfaff <blp@gnu.org>
8540 * Makefile.am: Maintainer-clean Makefile.in.
8542 * Makefile.am: Fixed redundant EXTRA_DIST line.
8544 * ascii.c: Comment fixes.
8545 (ascii_line_vert) Fixed overly aggressive range check.
8547 * display.c: Removed dead code.
8549 * list.q: Turn debugging on.
8550 (flush_table) New debug code.
8552 * sfm-read.c: (read_value_labels) malloc's the structure before
8553 trying to assign to its members.
8555 * sfm-write.c: Comment fix.
8557 * som-high.c: (som_submit_table) Sets som.t and som.d on each call
8559 (output_table) No arguments anymore--gets them through `som'
8560 global. New debug code. In crushed tables, now sets `htv' as
8561 well as `hv' to avoid bad confusion later.
8562 (dump_crush_page) New debug code.
8564 * som-low.c: (som_dump_crush_page) New debug code.
8566 Thu Mar 27 01:11:29 1997 Ben Pfaff <blp@gnu.org>
8568 All source files: Broke long lines into multiple lines.
8570 * ascii.c: (ascii_close_page) Uses host_system var in place of
8571 HOST_SYSTEM constant.
8573 * cmdline.c: (var syntax_message[]) Broke into
8574 pre_syntax_message[] and post_syntax_message[].
8575 (usage) Outputs both parts, separated by driver list.
8577 * error.h: Fixed broken formatting.
8579 * expr-opt.c: (str_search, str_rsearch) New functions.
8581 * misc.c: (blp_getdelim) Removed. All references changed to
8583 (str_search, str_rsearch) Removed.
8584 (memrmem) New function.
8586 * misc.h: (blp_getline) Removed. All reference changed to
8591 * filename.c: Includes "stat.h", not <sys/stat.h>.
8592 (blp_getenv) Uses host_system var instead of HOST_SYSTEM constant.
8594 * output.c: (outp_list_classes) Changed output formatting.
8596 * sfm-write.c: (write_header) Uses host_system var instead of
8597 HOST_SYSTEM constant.
8598 (write_rec_7_34) Extracts version numbers from the version string.
8601 * sort.c: Includes "stat.h", not <sys/stat.h>.
8603 * str.c: (strcasecmp) Removed.
8605 * title.c: (cmd_document) Uses host_system var instead of
8606 HOST_SYSTEM constant.
8608 * version.c: Generated on-the-fly by the Makefile instead of being
8611 * str.h: Comment fixes. Doesn't substitute for missing memmove or
8613 [!HAVE_STRNCASECMP] Declares strncasecmp().
8615 * version.h: Removed stray character. Comment fixes.
8616 (vars host_system, build_system) New vars.
8618 Mon Mar 24 21:47:31 1997 Ben Pfaff <blp@gnu.org>
8620 * Most source files: Changed formatting of copyright notice; fixed
8621 FSF address; reformatted to better conform to GNU standards;
8622 comment fixes. Added markups to prevent GNU indent from messing
8623 up my beautiful formatting :-).
8625 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
8626 that GNU indent markups can be passed through without problems.
8628 Wed Feb 19 21:30:31 1997 Ben Pfaff <blp@gnu.org>
8630 * get.c: Turned off debugging.
8632 * glob.c: (init_glob) Turned on save-file compression by default.
8634 * sfm-write.c: (sfm_write_case) Fixed bug which resulted in less
8635 compression than was possible in save files.

8645 (macro frq_extensions) Removed.
8646 (static vars min_n, max_degree) Removed, all references removed.
8647 (internal_cmd_frequencies) Doesn't handle extensions. Doesn't
8648 calculate `min_n', `max_degree'.
8649 (postcalc) Passes new arg to dump_statistics().
8650 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
8652 (dump_condensed) Adds variable name title.
8653 (sum_freqs) Removed.
8654 (calc_stats) Updated calculation algorithm.
8655 (dump_statistics) Removed warning for too-few observations.

8663 * som-frnt.c: (som_set_value, som_set_float, som_set_text)
8664 Improved debug code.
8666 * var.h: (enum series frq_*) Removed Fiasco extensions.

8670 * command.c: Added PROCESS IF to command table.
8672 * Lots & lots of places, removed checks for NULLs preceding calls
8673 to free_expression(), which itself checks.
8675 * descript.q: Removed Fiasco extensions. Removed optimizations
8676 for non-weighted active files. Implemented some options.
8677 Finished polishing output format. Comment fixes. Merged
8679 (static vars n_glob_miss_list, n_glob_valid, n_glob_missing,
8680 max_degree, min_n) Removed.

8682 (struct dsc_info_struct) Removed `min_n' member, all references
8684 (internal_cmd_descriptives) Removed calculation of min_n,
8685 max_degree. Only deals with one `calc' routine instead of two
8687 (precalc) Eliminated redundancy. Updated for changes to
8688 descriptives_proc structure.
8689 (calc) Moved here from `descript.g'. Rewritten to calculate
8690 statistics via `moments about the mean' rather than by summing,
8691 summing squares, summing cubes, and so on.
8692 (postcalc) Rewritten for new-style statistical calculation.
8693 (display) Removed support for displaying variables across rows.
8694 No longer crushes the descriptives table. Removed ancient code.
8695 Added display of N, by variable and listwise.
8697 * descript.g: Removed; merged into `descript.q'.
8699 * expr-evl.c: (evaluate_expression) Now returns a double. For
8700 numeric results, it returns the result as well as storing it in
8701 the passed `value' structure if non-NULL. For string results it
8702 just returns 0.0 and it must be passed non-NULL. Many references
8703 to this function were optimized by use of this change, especially
8704 but not exclusively in `compute.c'.
8706 * frequencies.g: Comment fix.
8708 * glob.c: (glob var process_if_expr) New global var.
8710 * postscript.c: (static var option_tab[]) Corrected entry for

8719 (sfm_write_dictionary) Sets `n_cases' to 0.
8720 (sfm_write_case) Increments `n_cases'.
8721 (sfm_close) Attempts to seek the system file back to the header
8722 and write the number of cases in its proper slot.
8724 * som-frnt.c: (som_insert_table) Masks off expansion options since
8725 only SOPT_X_NORM seems to work sensibly.
8727 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
8728 with a `fixed' value of 2.
8730 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
8732 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10

8746 * glob.c: (glob var err) Removed.
8748 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
8749 doesn't have to take into account number of value labels since
8750 they're in a subtable anyway. Also, doesn't display more than 10
8751 value labels since we can't yet break pages in subtables.
8753 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
8755 * som-frnt.c: (som_change_table_size) Simple change for elegance
8756 that shouldn't change behavior.
8757 (som_set_value) Comment fix.
8759 * som-high.c: (som_submit_table) Message fix.
8761 Wed Jan 22 21:54:00 1997 Ben Pfaff <blp@gnu.org>

8778 and ')' are not written to the output in strings as literals.
8780 * sfm-read.c: (sfm_read_dictionary) New argument.
8781 (read_header) New argument. Sets the information structure's
8782 values from the header information.

8784 bizarre Checker problem, I guess.
8785 (read_variables) Proper cleanup on lossage.
8787 * sfm.h: (struct sfm_read_info) New struct for use by
8788 sfm_read_dictionary().
8790 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
8791 currently used just for tables that can be dynamically resized and
8792 thus have to be allocated with arena_malloc() instead of
8793 arena_alloc(). All references changed.
8794 (som_change_table_size) New function.
8795 (som_insert_table) Bugfix: now inserts `cell', not `c'!
8797 * som-high.c: [GLOBAL_DEBUGGING] (check_table) Moved to som-low.c.
8798 (som_submit_table) [GLOBAL_DEBUGGING] Doesn't call check_table()

8829 the date is invalid.
8830 (parse_SDATE) Fixed swapped day, year.
8831 (parse_JDATE) Fixed bug for dates in 1582.
8832 (parse_DTIME) Allows days not between 1 and 31.
8833 (parse_numeric) Makes local copy of f.type for easier usage.
8836 * data-out.c: (convert_F) When outputting as scientific, properly
8837 sets f.type as fp->type.

8839 nitems. Changed strcpy to memcpy (no null terminator).
8840 (convert_date) Fixed FMT_JDATE: added 1900 to year.
8841 (convert_CCx) Essentially rewritten, but now it works.
8843 * display.c: (cmd_display) Added DISPLAY FILE LABEL (undocumented
8845 (display_documents) Implemented.

8875 (why was this here to begin with?!)
8877 * temporary.c: (save_dictionary) File label is copied only if
8878 non-NULL. Doesn't try to xstrdup() dictionary documents.
8879 Adapted so as to not irritate Checker.
8880 (free_dictionary) Only destroys var_by_name if non-NULL.
8882 * title.c: (cmd_file_label) Doesn't skip FILE, LABEL tokens.
8883 (cmd_document) Doesn't skip DOCUMENT token. Adds some header
8884 lines to the document, indents the document. Also, it works now.
8885 (add_document_line) New function.
8887 * var.h: (struct dictionary) Reordering.
8889 * vars-prs.c: (parse_variables) On lossage, only local_free()'s

8907 str_search() and str_rsearch(). Fixed tests for matches on
8908 OP_INDEX and OP_RINDEX.
8910 * filename.c: (good_getcwd) Removed as the new libc for Checker
8911 doesn't contain this bug, apparently.
8913 * misc.c: (str_search, str_rsearch) Changed order of arguments for
8914 consistency with GNU memmem.
8915 (blp_getdelim) Changed `len' from `int' to `size_t'.

8920 (som_create_table) Message fix.
8922 * som.h: Added gcc attributions to som_set_text(),

8924 zero_length[] instead of a literal null string to suppress gcc
8927 * sort.c: (do_external_sort) Fixed fencepost error on lossage.
8928 (allocate_cases) Decrements x_max so the last element of x[] can
8929 be used by the algorithm.

8937 * vars-prs.c: (fill_all_vars) More optimal implementation.
8939 * vfm.c: (dump_splits) Sets the last byte of temp_buf to a null

10830 * Many more changes to som.c especially, but these will not be
10831 documented as I have resolved to remove them. This patchlevel is

10902 frequencies.q, list.q, vars-prs.c, vfm.c: Removed reference to

10938 * Thanks to an unreliable IDE hard drive, I have spent the last
10939 day reconstructing my Debian GNU/Linux installation and redoing
10940 the previous day's changes--somehow I managed to save every file

10942 really be considered independent of the output.c, output.h changes
10945 * output.h, output.c: Moved the outp_configure_vec global var,
10946 outp_names struct, and enum set OUTP_S_* from output.h to output.c.

10949 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
10951 * The entire philosophy behind configuration of the output drivers
10952 changed. Now there is a termcap-type configuration where drivers
10953 to be read are determined beforehand, rather than parsing the
10954 entire output init file and storing it in memory & deciding what
10955 to actually use later. Faster & more memory-efficient at the same
10958 * output.c: Comment fix. Removed outp_init_drivers global var.

10971 (outp_list_drivers) Not implemented anymore.

11009 * ascii.c: (ascii_init_driver) Changed minimum number of lines per
11010 page from 29 to 15. Don't set a default for ops[OPS_INIT,
11011 OPS_DONE]. Writes the uninit string when the driver is closed.
11012 (ascii_open_page) Write the init string before the first page.
11013 (output_shorts) Form of main loop changed from `while' to `for'.
