15 * piechart.c Revised the API for piecharts.
17 * var.h Moved the definitions of freq_tab and freq out of var.h
18 and into frequencies.q where they belong.
20 Tue Nov 30 21:10:20 2004 Ben Pfaff <blp@gnu.org>
22 * flip.c: (flip_file) Check for off_t separately from fseeko(),
25 Tue Nov 30 08:47:41 2004 Ben Pfaff <blp@gnu.org>
27 * flip.c: (flip_file) If fseeko() is not available, use long int
28 for off_t. Thanks to "Marshall DeBerry" <mdb@radix.net> for
29 reporting the problem.
31 Mon Nov 29 12:20:59 WST 2004 John Darrington <john@darrington.wattle.id.au>
33 * examine.q factor_stats.[ch] Changed stderr to se_mean to avoid
36 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
38 * var-labs.c (var_to_string) Now returns null if the variable is null

41 value or the variable is null.
43 * hash.c (hsh_clear) Fixed a buglet.

58 Plugged some memory leaks
60 Mon Nov 15 23:47:40 2004 Ben Pfaff <blp@gnu.org>
62 Adopt GSL random number generators, paving the way for providing
63 the complete suite of random number generators on expressions.
65 * Makefile.am: Remove random.c, random.h.
71 * algorithm.c: (algo_default_random) Use GSL functions.
73 * casefile.c: (test_casefile) Use GSL RNG functions.
75 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
78 * sample.c: (cmd_sample) Use GSL RNG functions.
79 (sample_trns_proc) Ditto.
81 * set.q: (static var set_seed) Removed.
82 (static var seed_flag) Removed.
83 (static var rng) New variable.
84 (aux_stc_custom_seed) No seed value anymore, don't print anything.
85 (stc_custom_seed) Use new seed functions.
86 (seed_is_set) Removed.
87 (get_rng) New function that composes the entire external
89 (set_rng) New function.

92 Mon Nov 15 22:08:25 2004 Ben Pfaff <blp@gnu.org>
94 * expr-evl.c: (expr_evaluate) Fix XDATE.JDAY formula. Thanks to
95 John Darrington <john@darrington.wattle.id.au> for reporting this
98 Tue Nov 16 13:19:18 WST 2004 John Darrington <john@darrington.wattle.id.au>
100 * permissions.c command.def Added the PERMISSIONS command
103 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
105 * q2c.c: (dump_header) Don't try to emit #includes at very top of
106 output file because that will precede #include <config.h>, which
108 (main) Add needed headers to /* (header) */ code.
110 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
112 Instead of making system or portable file readers responsible for
113 dropping and reordering variables, make them read full cases and
114 let the caller take care of any changes.
116 * get.c: New "case map" structure to handle this. Use for GET,
117 IMPORT, MATCH FILES. Essentially rewrite the whole file.
119 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
120 changed appropriately.
122 * sfm-read.c: (sfm_read_case) Ditto.
124 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
126 Decided that case_serialize() and case_unserialize() were too
127 abstract. Also we need a couple more functions to avoid excessive
128 copying for data in/out fast paths.
130 * case.c: (case_serial_size) Removed.
131 (case_serialize) Rename case_to_values() and make its argument
132 explicitly an array of union values.
133 (case_unserialize) Rename case_from_values() and make its argument
134 explicitly an array of union values.
135 (case_data_all) New function.
136 (case_data_all_rw) New function.
138 * casefile.c: (struct casefile) Change buffer from array of
139 unsigned char to array of union value for better accuracy.
140 Redefine buffer_used and buffer_size in terms of values, not
141 bytes. Remove case_size because it is now redundant with
142 value_cnt. Fix up all references to these members.
144 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
146 * barchart.c: (struct subcat) Make `label' member const to silence
147 GCC warning with -Wwrite-strings.
149 * cartesian.c: (struct dataset) Ditto.
151 * case.c: Don't re-define NDEBUG if already defined.
152 Add lots of comments.
154 * str.c: Fix includes.
156 * crosstabs.q: Fix includes.
158 * examine.q: Fix includes. Fix GCC warning about unused
161 * frequencies.q: (stat macro) Removed and replaced where used by
164 * list.q: Fix includes.
166 * oneway.q: Fix includes.
168 * piechart.c: Fix includes. Only define M_PI if not already
171 * sfm-read.c: (bswap) New function.
172 (bswap_int32) Write in terms of bswap.
175 * str.c: (ds_data) Add external definition here, needed because
176 str.h has only an `extern inline' version.
178 * value-labels.c: Fix includes.
180 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
182 Instead of providing a system or portable file writer with a raw
183 case in the format needed for output, provide it with a regular
184 case. The writer takes care of any needed translation.
186 * aggregate.c: Adopt new scheme for AGGREGATE.
187 (struct agr_proc) sfm_agr_case member removed.
188 (write_case_to_sfm) Removed because the new interface is easier to
191 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
193 * pfm-write.c: Implement new scheme.
195 * sfm-write.c: Ditto.
197 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
199 Instead of treating `struct file_handle' as a class to subclass
200 into data files, system files, and portable files, instead use it
201 as a helper that coordinates access. Now it is opaque, too.
203 This means that most references to a struct file_handle are now
204 changed into references to one of struct dfm_reader, struct
205 dfm_writer, struct sfm_reader, struct sfm_writer, struct
206 pfm_reader, or struct pfm_writer, according to what's being read
209 Most related changes are only worth summarizing briefly.
211 * dictionary.c: (dict_clear) Destroy aux data in deleted
213 (dict_clear_aux) New function.
214 (dict_create_var) Initialize aux, aux_dtor.
215 (dict_delete_var) Destroy aux data in deleted variable.
217 * file-handle.h: (struct fh_ext_class) Removed.
218 (struct file_handle) Removed.
219 (fh_init_files) Removed.
221 * file-handle.q: Changed references to a handle's `private' member
222 to direct references.
223 (struct private_file_handle) Renamed file_handle.
224 Add next, open_cnt, type, open_mode, aux members.
225 (struct file_handle_list) Removed.
226 (extern var inline_file) Removed.
227 (static var file_handles) Changed from file_handle_list * to
229 (create_file_handle) Initialize new members.
230 (fh_close_handle) Removed.
231 (mode_name) New function.
232 (fh_open) New function.
233 (fh_close) New function.
234 (fh_parse_file_handle) Renamed fh_parse().
236 * glob.c: (init_glob) Remove fh_init_files() call.
238 * aggregate.c: use sfm_writer.
239 (create_sysfile) Removed because the new interface is simpler.
241 * apply-dict.c: Use sfm_reader.
243 * data-list.c: Use dfm_reader.
245 * file-type.c: Use dfm_reader.
247 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
249 * inpt-pgm.c: Use dfm_reader.
251 * print.c: Use dfm_writer.
253 * sysfile-info: Use sfm_reader.
255 * dfm-read.c: Adopt new file handle infrastructure.
257 * dfm-write.c: Ditto.
261 * pfm-write.c: Ditto.
265 * sfm-write.c: Ditto.
267 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
269 Break dictionary functions into separate header file.
271 * dictionary.h: New file.
273 * var.h: Moved dict_*() functions to dictionary.h.
275 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
277 Get rid of procedure-specific union in struct variable, using
278 instead a void * pointer and a destructor function.
280 Most related changes are only worth brief summaries.
282 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
283 old p.crs member in struct variable.
285 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
286 of old p.frq member in struct variable.
288 * histogram.c: (draw_histogram) Takes new freq_tab arg because
289 it's no longer possible to grab this from var->p.frq.
291 * piechart.c: (draw_piechart) Ditto.
293 * group.c: (group_proc_get) New function.
295 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
302 * main.c: (execute_command) Clear aux data in default_dict after
303 each command. (It's debatable whether this should be done.)
305 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
306 member in struct variable.
308 * means.q: Get rid of integer mode, which is not included in
309 recent SPSS and was the only code that wanted per-variable private
312 * var.h: (struct crosstab_proc) Removed.
313 (struct frequencies_proc) Removed.
314 (struct list_proc) Removed.
315 (struct get_proc) Removed.
316 (struct means_proc) Removed.
317 (struct matrix_data_proc) Removed.
318 (struct match_files_proc) Removed.
319 (lots of enums) Removed.
320 (struct variable) Removed members `p', `get'. Add member
323 * vars-atr.c: (var_attach_aux) New function.
324 (var_detach_aux) New function.
325 (var_clear_aux) New function.
326 (var_dtor_free) New function.
327 (discard_variables) Use NULL instead of inline_file.
330 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
332 * value-labs.c Fixed the implmentation of value_to_string, so
333 that it properly handles alpha values.
335 * oneway.q Changed instances where labels were being probed manually,
336 to use the canonical {var,value}_to_string functions
338 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
340 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
341 plots. Changed the API of the cartesian plot to be a much lower level
344 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
346 * examine.q Added some of the parametric calculations
348 * factor_stats.[ch] Created
350 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
352 * examine.q Changed the definition of factors to be a composite, and
353 dealt with the consequences.
355 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
357 * examine.q Fixed problem where examine wasn't dealing properly with
360 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
362 * oneway.q Fixed problem where oneway wasn't dealing properly with
365 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
367 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
368 command which had settings didn't get the appropriate code
371 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
372 to convert variables/values to strings.
374 * examine.q Added framework for the EXAMINE command.
376 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
378 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
379 subcommand types. Changed frequencies.q to use it rather then the
380 custom parser. Dealt with the consequences. Added a test for NTILES
381 subcommand of frequencies.
383 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
385 * oneway.q Fixed up the behaviour when given missing values
387 * levene.c oneway.q Fixed a buglet with the levene statistic and
388 incorporated the levene test into the oneway command.
390 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
391 global scope, since they're only relevant to T-TEST
393 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
395 * group.c group.h group_proc.h levene.c oneway.q t-test.q
397 Made the t-test more consistent
398 with the way it handles groups. That is, it now uses a hash instead
399 of an array of 2. Also, made the levene.c file independent of the
400 implementation of the t-test. So now levene should be fine for both
403 * Added an oneway.q file for one way anova
405 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
407 * descript.c: (cmd_descriptives) Remove harmless but bogus test in
410 Mon May 31 20:45:24 2004 Ben Pfaff <blp@gnu.org>

415 (data_list_trns_free) Free dls->delims.
417 * t-test.q: (tts_custom_pairs) Free vars.
418 (ssbox_one_sample_init) Fix tab_vline() argument.
419 (ssbox_independent_samples_init) Ditto.
420 (trbox_paired_init) Ditto.
421 (trbox_one_sample_init) Ditto.
423 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
425 Generalize casefiles to the extent that we can use them for
426 sorting and other kinds of data transformations. Change cases to
427 be copy-on-write to improve memory efficiency in common cases.
428 Every access to a member of a `struct ccase' was changed to be a
429 call to a case_*() function, especially case_data(), case_num(),
430 case_str(), or case_data_rw(). Many instances of a local variable
431 named "case_num" were changed to "case_idx" as a consequence.
432 Many `struct ccase *' were changed to actual `struct ccase'
433 because of copying semantics of cases. In several places there
434 was a choice between updating debug code to work with the new ADTs
435 or just deleting it because it was useless; I chose to delete it.
437 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
443 * aggregate.c: (struct agr_proc) Change type of `sort' to
444 sort_criteria *. Add `break_vars', `break_var_cnt' members.

446 `agr_case' to type `struct ccase'.
447 (cmd_aggregate) Deal with new members. Use case_create(),
448 sort_active_file_in_place(), sort_active_file_to_casefile().
449 (agr_destroy) Deal with new members.
450 (aggregate_single_case) Ditto.
451 (dump_aggregate_info) Ditto.
452 (initialize_aggregate_info) Ditto.
453 (agr_to_active_file) Ditto.
454 (presorted_agr_to_sysfile) Ditto.
455 (sort_agr_to_sysfile) Removed.
457 * alloc.c: (out_of_memory) Make non-static.
459 * alloc.h: Prototype out_of_memory().
461 * casefile.c: Switched from a linked list in-memory representation
462 to a two-level array-style representation. The linked list was
463 appropriate when we could stick a header onto cases, but that's no
464 longer the case. Also, the two-level array will allow for random
465 in-memory access in case that's ever wanted. Also added the
466 concept of a `destructive casereader', one that destroys cases in
467 the underlying casefile as they are read out.
468 (macro CASES_PER_BLOCK) New macro.
469 (struct casefile) New members `value_cnt', `case_list_size',
470 `case_acct_size', `being_destroyed', `cases'. Removed `head',
472 (struct casereader) Removed `cur'. Added `destructive', `c'.
473 (global var casefiles) Made static.
474 (static var case_bytes) New var.
475 (casefile_create) Takes a value count, not a case size in bytes,
476 to conform to the case interface. All callers updated. Deal with
477 new and removed members.
478 (casefile_destroy) Deal with new and removed members.
479 (casefile_sleep) New function.
480 (casefile_get_case_size) Removed.
481 (casefile_get_value_cnt) New function.
482 (casefile_append) Rewritten to deal with new and removed members.
483 (casefile_append_xfer) New function.
484 (write_case_to_disk) Use case_serialize().
485 (call_posix_fadvise) Removed because posix_fadvise64 segfaults.
486 Couldn't figure out why.
487 (casefile_to_disk) Don't call call_posix_fadvise. Rewritten to
488 deal with new and removed members.
490 (merge_sort) Removed.
491 (casefile_sort) Removed.
492 (casefile_get_reader) Deal with new and removed members.
493 (casefile_get_destructive_reader) New function.
494 (reader_open_file) Make code more readable. Create case for
496 (casereader_get_casefile) New function.
497 (casereader_read) Deal with new and removed members. Now returns
498 a copy of the case, so that the caller is responsible for
499 destroying the returned case.
500 (casereader_read_xfer) New function.
501 (casereader_destroy) Destroy reader's case.
502 (test_casefile) Second arg is now a value count, all callers
503 updated. Now tests destructive readers too.
504 (get_random_case) Deal with new case ADT.
505 (write_random_case) Ditto.
506 (read_and_verify_random_case) Ditto.
508 * crosstabs.q: Remove debug code.

517 * expr-prs.c: Remove debug code.
519 * exprP.h: Remove debug code.
521 * flip.c: (flip_file) Use fseeko() if available.
523 * formats.c: Remove debug code.
525 * get.c: Remove debug code.
526 (struct mtf_file) Change `input' from `union value *' to `struct
527 ccase', all references updated.
529 * levene.c: (levene) Deal with new case, casefile ADTs.
531 * list.q: Remove debug code.
533 * loop.c: Remove debug code.
535 * matrix-data.c: Remove debug code.
537 * means.q: Remove debug code.
539 * mis-val.c: Remove debug code.
541 * pfm-read.c: Remove debug code.

562 (sort_active_file_in_place) New function.
563 (sort_active_file_to_casefile) New function.
564 (parse_sort) Renamed sort_parse_criteria(), rewritten & interface
565 changed, all callers updated.
566 (destroy_sort_cases_pgm) Renamed sort_destroy_criteria(),
567 rewritten & interface changed, all callers updated.
568 (sort_cases) Renamed sort_execute(), rewritten & interface
569 changed, all callers updated.
570 (struct internal_sort) Removed.
571 (do_internal_sort) Rewritten, interface changed.
572 (destroy_internal_sort) Removed.
573 (compare_case_dblptrs) Use sort_criteria instead of sort_case_pgm.
574 (struct initial_run) Removed; an initial run is now just a
576 (compare_initial_runs) Rewritten.
577 (struct external_sort) Changed almost completely.

591 (read_temp_file) Removed.
592 (struct record_run) Change `record' from `struct case_lit *' to
594 (struct initial_run_state) Remove `idx_to_fv', `free_list',
595 `file_idx', `output_file'. Add `run', casefile'. Change
596 `last_output' from `struct case_list *' to `struct ccase'.
597 (write_initial_runs) Change interface, rewrite.
598 (sort_sink_write) Renamed process_case(), changed interfaced,

784 (reader_open_file) Ditto.

825 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
827 We're abusing the current ASCII driver by telling it to allocate a
828 9999-line, 9999-character page in the tests. This causes some
829 systems to curl up and die because it allocates 20 MB of
830 contiguous RAM. This change alleviates at least part of the
831 problem. It is mostly a stop-gap until the new output system is
834 * ascii.c: (struct line) New structure.

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

872 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
874 Rework moments routines for improved numerical stability based on
875 Michael Kiefte's advice. Any bugs or remaining numerical problems
876 are still mine though.
878 There is now a struct moments1 for use with one-pass moments. It
879 uses a provisional means algorithm as an attempt to improve
880 accuracy of higher moments. The older struct moments now only
881 handles two-pass moments.
883 * aggregate.c: Use moments1 instead moments.
885 * descript.c: Revert previous change, which is no longer needed
886 due to the moments revision.

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

912 MOMENT_MEAN is needed.
914 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
918 fixed problem with parsing in match_statistic() causing
919 "DESCRIPTIVE STAT=MEAN." to barf.
921 "MEAN" is now default if "SORT" given without specification.
923 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
924 generally less forgiving of syntax errors: better to have it do
925 nothing and type it in again then to not know what it actually did
928 z-score transformation now checks score for user-missing values
929 and checks std_dev for SYSMIS.
931 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
933 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:

985 Tue Mar 30 22:04:19 2004 Ben Pfaff <blp@gnu.org>
987 * vfm.c: Had to get last call to multipass_split_output() inside
988 open_active_file()/close_active_file() pairing, so introduce new
990 (internal_procedure) Move procedure() code here, except for calls

1025 nonterm_node's n earlier.
1026 (generic_str_func) Ditto.

1030 Add support for multipass procedures. Rewrite DESCRIPTIVES to

1190 Removed support for missing values because we're never called with
1191 missing values. Use set_number() or set_number_errno() instead of
1192 rnc or frnc. Removed any stuff that caused trouble in testing.
1193 We can re-add it later if it really slows anything. Fix some

1319 Added abort() after lots of assert(0) invocations to avoid some

1361 Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
1363 Changed DFM from open-at-first-access to explicit-open. Before,
1364 calling dfm_get_record() or dfm_put_record() would automatically
1365 open the file. Now, you have to call dfm_open_for_reading() or

1483 Fixed cmd_parse() so that it always skips past a full command
1484 name. A few special commands for which this would be bad get
1485 special treatment. This lets us drop code for skipping past the
1486 end of a command name in most cmd_*() functions. It's not worth
1487 listing all the commands affected.
1489 * command.c: (struct command) Remove `cmd' member, replace by
1490 `name' member, all references updated. Remove `word', `next',
1491 `skip_entire_name' members.

1550 Added a handler for SIGWINCH so that viewlength and viewwidth follow
1551 changes as the window size is changed.
1553 Added fallback to set viewlength and viewwidth from LINES and COLUMS
1554 environment variables if other methods are not available.
1556 glob.c: Removed a lot of global variables from glob.c and encapsulated
1559 random.c: Tidied up the way the random seed is set.

2761 NO_RETURN or PRINTF_FORMAT instead.
2763 * alloc.h: Move definitions for local_alloc(), local_free() here
2764 from ../pref.h.orig and simplify.

2848 Start working on a new output driver system, one that doesn't suck
2849 so much, by adding a "device-independent" output driver. The idea
2850 is to write out only a single output stream, then use separate
2851 processes to translate them into whatever formats we want. This
2852 is similar to how "groff" works with its various output drivers
2853 (grops, grotty, grodvi, ...).

2879 * Removed bletcherous alloca() workarounds for AIX from top of
2880 many files. AIX can use the alternative alloca() implementation

3212 (dict_get_vars) New function, replaces fill_all_vars().
3213 (dict_create_var) New, replaces create_variable(). Interface
3214 drops `type' parameter, using a zero `width' to designate numeric.
3215 (dict_clone_var) New, replaces dup_variable().
3216 (dict_rename_var) New, replaces rename_variable().
3217 (dict_lookup_var) New, replaces find_variable(),

3250 itself. Use dict_set_documents(), dict_set_split_vars().
3252 * temporary.c: (cancel_temporary) Also set temp_dict to NULL after
3253 calling dict_destroy().
3255 * data-list.c: (dls_var_spec) Remove `type' member, replace by

3276 other dictionary functions.
3278 * title.c: (add_document_line) Use dict_get_documents(),
3279 dict_set_documents().
3281 * vars-atr.c: (discard_variables) Use dict_clear(default_dict),
3282 reset default_handle by hand. dict_clear() will clear vectors so
3283 there's no need for that by hand.
3285 * vfm.c: (close_active_file) Move call to finish_compaction()
3286 earlier, so that we can do the compaction as a single step using
3287 dict_compact_values(). Use dict_clear_vectors().

3304 * aggregate.c: Eliminate separation of weighted and unweighted
3305 case. It made the code too obscure and I doubt it was actually
3306 faster. Instead, all code uses the "weighted" code, because
3307 that's a generalization of the "unweighted" code.
3310 (parse_aggregate_functions) No need to set FWEIGHT.
3311 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
3312 (dump_aggregate_info) Ditto.

3319 (aggregate_single_case) Don't use approx_ne().

3371 * command.c: Move prototypes for cmd_*() functions to command.h.
3373 * command.h: Prototypes for cmd_*() functions moved here from

3923 Fri Dec 12 13:31:58 2003 Ben Pfaff <blp@gnu.org>

3944 assertions on pointers strictly compliant. Removed _ prefixes on
3945 some function parameter names.

3948 functions removed from common.c: xmalloc, xcalloc, xrealloc,

4592 Thu Jun 3 18:40:42 1999 Ben Pfaff <blp@gnu.org>
4594 Using alphanumeric variables in functions under AGGREGATE
4595 segfaulted. Fixed. Thanks to Dr. Dirk Melcher
4596 <BZN-mdksh@t-online.de> for reporting this bug.
4598 * aggregate.c: (parse_aggregate_functions) When setting the
4599 FSTRING bit, also allocate memory for the `string' member of
4601 (free_aggregate_functions) Free iter->string. Don't use the
4602 non-function bits when indexing the array of functions.
4603 [DEBUGGING] (debug_print) Don't use the non-function bits when
4604 indexing the array of functions.
4606 Sun May 30 00:00:54 1999 Ben Pfaff <blp@gnu.org>
4608 Under certain circumstances, the final case would be omitted from
4609 the results of an AGGREGATE operation. Fixed. Thanks to Dr. Dirk
4610 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4612 * aggregate.c (agr_00x_end_func): Increment number of cases in
4613 sink before writing case. For streams that keep track of how many
4614 cases there are based on this value, this means that the last case
4615 will be read in on the next stream read.
4617 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
4619 Undefined behavior was invoked by referencing a freed pointer.
4621 * vfm.c (memory_stream_write): Free pointer *after* checking for
4624 Sat May 29 22:02:22 1999 Ben Pfaff <blp@gnu.org>
4626 A wrong record size was displayed when paging the active file to
4629 * vfm.c: (memory_stream_write) Fix off-by-one error.
4631 Sat May 29 21:50:26 1999 Ben Pfaff <blp@gnu.org>
4633 Not having enough temporary space for sorting caused a core dump.
4636 * sort.c: (allocate_cases) Initialize i.
4638 Sat May 29 21:40:54 1999 Ben Pfaff <blp@gnu.org>
4640 Syntax errors in function descriptions on AGGREGATE caused core
4643 * aggregate.c (cmd_aggregate): Don't free agr_dict after calling
4644 free_aggregate_functions(), since that function already frees
4647 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
4649 A null pointer was dereferenced, causing a core dump, when
4650 PERCENTILES was specified on FREQUENCIES. This fixes the problem,
4651 but PSPP still doesn't calculate percentiles. Thanks to Regnor
4652 Jernsletten <rjernsle@eunet.no> for reporting this problem.
4654 * arena.c: (arena_malloc) If the arena hasn't been initialized
4655 already, initialize it.
4657 Sat May 29 20:47:29 1999 Ben Pfaff <blp@gnu.org>
4659 * Makefile.cygwin: New file supplied by Hankin <hankin@dunno.com>
4660 for compilation with Cygnus Windows B20. Not used by other
4663 Sat May 29 20:36:04 1999 Ben Pfaff <blp@gnu.org>
4665 SORT always sorted in ascending order. Fixed. Thanks to Dr. Dirk
4666 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4668 * sort.c: (compare_case_lists) Reverse sense of comparison if
4669 sorting in descending order.
4670 (compare_record) Ditto.
4672 Tue Mar 9 13:18:54 1999 Ben Pfaff <blp@gnu.org>
4674 SPLIT FILE with a string variable caused a core dump. Fixed.
4676 * vfm.c: If the variable is a string then make a temporary value
4677 struct pointing to it. The underlying problem is a lot bigger
4678 than this (see TODO) but this is a stopgap for the simple case at
4681 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
4683 Nested INCLUDEs didn't work. Fixed.
4685 * getline.c: (getl_include) Set first_line to NULL in allocated
4688 Tue Mar 9 13:13:46 1999 Ben Pfaff <blp@gnu.org>
4690 The MATCH FILES procedure set the values of variables not present
4691 to 0. It should have been SYSMIS. This is now fixed.
4693 * get.c: (mtf_delete_file_in_place) Replace 0.0 by SYSMIS.
4695 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>
4697 The REMARK command was too aggressive about skipping lines. It
4698 didn't like being the last command in a file.
4700 * command.c: (cmd_remark) Call get_entire_line() instead of
4703 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
4705 Comment parsing wasn't consistent with the rest of the code in its
4706 idea of where one command ends and another starts. This meant
4707 that sometimes commands would be mysteriously ignored. Thanks to
4708 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4710 * command.c: (parse_cmd) Hand off comment parsing to new function
4711 skip_comment() in lexer.c.
4712 * lexer.c: (skip_comment) New function.
4714 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
4716 The TABLE subcommand on MATCH FILES worked only erratically at
4717 best. This fixes it. Thanks to Dr. Dirk Melcher
4718 <BZN-mdksh@t-online.de> for reporting this bug.
4720 * get.c: (mtf_compare_BY_values) When comparing string values, a
4721 difference of 1 is still a difference :-)
4722 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
4723 advance TABLE files automatically when matched. Comment fixes.
4725 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>
4727 VARIABLE LABELS rejected a slash before the first variable
4728 specification, contradicting the documentation. Thanks to Walter
4729 M. Gray <graywm@northernc.on.ca> for reporting this bug.
4731 * var-labs.c: (cmd_variable_labels) Ignore a leading slash in
4732 command specification.
4734 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>
4736 Because of an incorrect optimization in memory allocation,
4737 CROSSTABS sometimes segfaulted when asked to output multiple
4738 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4741 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
4742 are passed to output_pivot_table() for its use.
4743 (output_pivot_table) Instead of assuming the number of columns is
4744 constant, keep track with maxcols. In general mode, use maxcells
4745 to determine whether more matrix cells need to be allocated.
4747 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
4749 CROSSTABS didn't display value labels for column and row
4750 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4753 * crosstabs.q: (table_value_missing) If the specified value has a
4754 value label for this variable, then show it instead of the raw
4756 (display_dimensions) Delegate display of value_labels to
4757 table_value_missing.
4759 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
4761 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
4762 <BZN-mdksh@t-online.de> for reporting this bug.
4764 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
4765 if the file isn't declared as binary.
4767 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
4769 MATCH FILES corrupted memory and dumped core on some syntax
4772 * get.c: (cmd_match_files) Set file->handle to NULL before
4774 (mtf_free_file) Don't free a null dictionary.
4776 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
4778 MATCH FILES should set numeric values not available to the
4779 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
4780 <BZN-mdksh@t-online.de> for reporting this bug.
4782 * get.c: (mtf_processing) Set unused records to system-missing,
4785 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>
4787 KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
4788 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
4790 * temporary.c: (save_dictionary) Initialize var_by_name AVL tree
4791 in newly created dictionary, and add each copied variable to the
4794 Mon Jan 18 15:04:48 1999 Ben Pfaff <blp@gnu.org>
4798 * get.c: (trim_dictionary) Free variable list for KEEP after
4801 Mon Jan 18 12:57:36 1999 Ben Pfaff <blp@gnu.org>
4803 Some systems didn't like the way open_file was coded. Thanks to
4804 Hankin <hankin@rogue.consultco.com> for pointing this out.
4806 * filename.c: (open_file) Don't try to store stdin, stdout,
4807 stderr as part of an array, because that doesn't always work.
4809 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
4811 The SAVE procedure didn't save long string variables properly.
4812 Fixed by this patch. Thanks to Hankin
4813 <hankin@rogue.consultco.com> for this patch.
4815 * sfm-write.c: (write_variable) Fix off-by-one error in writing
4816 out variable pad records.
4818 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
4820 Previously, if PRINT SPACE were given a negative argument, it
4821 would report an error, then spin in an (almost) infinite loop.
4822 This fixes that behavior.
4824 * print.c: (print_space_trns_proc) After reporting a negative
4825 argument, set number of lines to print to 1.
4827 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
4829 SPSS 8.0 outputs some new record types in its system files, and it
4830 allows longer value labels. Accept these system files.
4832 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
4833 11 emitted by SPSS 8.0.
4835 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
4837 The LIST procedure was too conservative in allocating space for
4838 buffers, which caused a bug that only showed up with very long
4839 output variables. Thanks to Hankin <hankin@dunno.com> for this
4842 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
4844 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
4846 Typo meant string format specifiers weren't checked properly. I
4847 think that Hankin <hankin@dunno.com> sent me this report, but I'm
4848 willing to be corrected on this point.
4850 * format.c: (check_string_specifier) Fix obvious typo.
4852 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>
4854 Using $CASENUM in an expression didn't work. Here's a fix.
4855 Thanks to Dirk Melcher <BZN-mdksh@t-online.de> for reporting this
4858 * expr-evl.c: (evaluate_expression) Add OP_CASENUM case.
4860 * expr-opt.c: (dump_node) OP_CASENUM is acceptable.
4862 Tue Jan 5 12:47:48 1999 Ben Pfaff <blp@gnu.org>
4864 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
4865 other behavior, *sigh*. This patch hopefully fixes that. This
4866 time I've actually tested it.
4868 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
4870 * data-list.c: (read_from_data_list_free,
4871 read_from_data_list_list) Call parse_string_as_format() directly
4872 without mucking around with the field width.
4874 Tue Jan 5 12:31:19 1999 Ben Pfaff <blp@gnu.org>
4876 Occasionally, you may encounter a script that wants to be
4877 interpreted in interactive mode. Make -i emulate this behavior to
4878 allow such scripts to be executed with PSPP.
4880 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
4882 * cmdline.c: (pre_syntax_message[]) Update -i description.
4884 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
4885 when -i is given on the command line) don't treat unindented lines
4886 as starting a new command.
4888 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
4890 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
4891 mostly caused by local initialized aggregates. After egcs is
4892 fixed upstream these can be removed, but for now they're not a big
4895 * ascii.c: (ascii_postopen_driver) Checker chokes on local
4896 initialized arrays. Avoid this.
4898 * sfm-write.c: (sfm_write_dictionary) Don't use a local
4901 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
4903 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
4904 following changes avoid. Currently I compile sources with egcs
4905 1.1.1 and gcc 2.7.2.3 before sending them out.
4907 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.
4909 * ascii.c: (option_tab[]) Initialize all struct members.
4911 * avl.h: (avl_traverser_init) New macro.
4913 * command.c: (DEFCMD, UNIMPL macros, cmd_table[]) Initialize all
4916 * crosstabs.q: (enum_var_values) Use new hsh_iterator_init()
4919 * hash.c: Comment fix.
4921 * hash.h: (hsh_iterator_init) New macro.
4923 * html.c: (option_tab[]) Initialize all struct members.
4925 * pfm-write.c: (write_value_labels) Use new avl_traverser_init()
4928 * postscript.c: (option_tab[]) Initialize all struct members.
4929 (output_encodings, preclose, dump_lines) Use new
4930 hsh_iterator_init() macro.
4932 * sfm-write.c: (write_value_labels) Use new avl_traverser_init()
4935 * sysfile-info.c: (describe_variable) Use new avl_traverser_init()
4938 Thu Nov 19 12:32:45 1998 Ben Pfaff <blp@gnu.org>
4940 * data-in.c: Examined each of the parsing functions to make sure
4941 that they wouldn't dump core if they were passed a string of the
4942 wrong length, since now the DATA LIST FREE/LIST routines don't
4943 check for field width before passing it to the data parser.
4944 (parse_RBHEX, parse_AHEX) Reject odd length input.
4945 (parse_string_as_format) Reject input that's too short or too
4948 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad
4949 a field to its entire declared output width then pass it to the
4950 data-in parsing routines. This contradicted the documented
4951 behavior. This is fixed in these changes. Thanks to Mark H. Wood
4952 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
4953 free-format parsing that differed from SPSS.
4954 (cut_field) Commas and spaces are treated identically. Returns
4955 the proper column instead of a fixed 1 value.
4956 (parse_field) Removed.
4957 (read_from_data_list_free, read_from_data_list_list) Call
4958 parse_string_as_format directly instead of parse_field.
4960 * heap.c: (heap_delete) Stylistic fixes.
4962 Sun Aug 9 11:12:13 1998 Ben Pfaff <blp@gnu.org>
4964 * loop.c: (loop_2_trns_proc) Formatting fix.

4968 * var.h: (glob var FILTER_before_TEMPORARY) New global var.
4970 * vfm.c: (macro FILTERED) New.

4972 (process_active_file_write_case) Use FILTERED.
4973 (setup_filter) Set filter_var.
4974 (close_active_file) Delete the filter if not
4975 FILTER_before_TEMPORARY.
4976 (procedure_write_case) Use FILTERED.
4978 Sat Aug 8 00:20:14 1998 Ben Pfaff <blp@gnu.org>
4980 * crosstabs.q: Changed /PIVOT={ON,OFF} to /FORMAT={PIVOT,NOPIVOT}.
4982 * data-in.c: (parse_day_count) Message fix.
4983 (parse_month) Style fix.
4985 * data-list.c: (struct data_list_pgm) New member eof.
4986 (cmd_data_list) Init eof to 0.
4987 (do_reading) Implement the /END subcommand and read-past-eof
4990 * do-if.c: Include stdio.h when debugging.
4991 (cmd_else_if) Make sure the command is .-terminated.
4993 * glob.c: (init_glob) Capitalize the command prompt.
4995 * inpt-pgm.c: (end_case_trns_proc) Debugging message.
4996 (end_file_trns_proc) Debugging message.
4998 * loop.c: (internal_cmd_loop) Make it work when there's no loop
5000 (loop_2_trns_proc) Enable MXLOOPS (why was this disabled?)
5002 * main.c: (dump_token) Make kwtab[] const.
5004 * set.q: Spelling, comment fixes.
5006 * sysfile-info.c: (cmd_display) DISPLAY VECTORS not DISPLAY
5009 * vars-prs.c: (fill_all_vars) Style fix.
5011 * vfm.c: (index_to_varname) Return const.
5013 Tue Aug 4 23:49:23 1998 Ben Pfaff <blp@gnu.org>
5015 * Changes in many source files for partial -ansi -pedantic and
5016 no-debugging compliance: Remove trailing common in enum
5017 declarations; add `unused' attributes; insert some appropriate
5020 * cmdline.c: (parse_command_line) Add new --testing-mode flag.
5022 * command.c: (shell) Make static.
5023 (run_command) Make static.
5025 * data-list.c: (dump_fixed_table) Remove use of local_strdup().
5027 * dfm.c: (cmd_begin_data) I18n fix.
5029 * error.c: (verbose_msg) Define if __STRICT_ANSI__.
5031 * error.h: (macro verbose_msg) Define if __STRICT_ANSI__.
5033 * expr-opt.c: (evaluate_tree) Don't initialize local arrays if
5036 * file-handle.q: Don't prepend the source file directory name to
5037 the data file name. (Ongoing issue.)
5038 (prepend_current_directory) Comment out.
5039 (internal_cmd_file_handle) Don't call prepend_current_directory().
5040 (fh_get_handle_by_filename) Ditto.
5042 * filename.c: Append zero byte to readlink() return value.
5044 * getline.c: (getl_read_line) I18n fix.
5046 * lexer.h: Don't use gcc features if __STRICT_ANSI__.
5048 * misc.h: Don't use gcc features if __STRICT_ANSI__.
5050 * pfm-write.c: (bufwrite) Don't try to increment a void * pointer
5053 * postscript.c: (output_encodings) Don't use local_strdup().
5056 * print.c: Don't use gcc features if __STRICT_ANSI__.
5058 * q2c.c: (dump_vars) Don't put a , at the end of the last enum.
5060 * recode.c: (parse_src_spec) Fully brace nested if's.
5062 * set.q: (global var set_testing_mode) New var.
5064 Wed Jul 29 22:01:44 1998 Ben Pfaff <blp@gnu.org>
5066 * ascii.c: Add some more `unused' attributes that only come into
5067 play when NDEBUG is defined.

8373 of comments in script files. Now more liberal on criteria for
8374 performing a state transition--if *anything* happened correctly,
8375 not just if *everything* happened correctly.
8377 * data-out.c: (convert_F) Comment fix. Why in the fsck does
8378 Checker segfault on formatting large numbers and why in the fsck
8379 hadn't I noticed this before?
8381 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
8383 * list.q: (cmd_list) Commented out the actual output routine
8384 because of various problems. Probably will abandon the idea of
8385 using the general `crushed tables' for the LIST procedure.
8387 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
8388 clearing it. Allocates a new var_by_name dictionary before trying
8389 to add members to it.
8391 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
8392 `sib'. Changed type of `node' argument.
8393 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
8395 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
8396 [DEBUGGING] Only deletes the variable from var_by_name if that var

8420 trying to assign to its members.
8422 * sfm-write.c: Comment fix.
8424 * som-high.c: (som_submit_table) Sets som.t and som.d on each call
8426 (output_table) No arguments anymore--gets them through `som'
8427 global. New debug code. In crushed tables, now sets `htv' as
8428 well as `hv' to avoid bad confusion later.

8483 (vars host_system, build_system) New vars.
8485 Mon Mar 24 21:47:31 1997 Ben Pfaff <blp@gnu.org>
8487 * Most source files: Changed formatting of copyright notice; fixed
8488 FSF address; reformatted to better conform to GNU standards;
8489 comment fixes. Added markups to prevent GNU indent from messing
8490 up my beautiful formatting :-).
8492 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
8493 that GNU indent markups can be passed through without problems.
8495 Wed Feb 19 21:30:31 1997 Ben Pfaff <blp@gnu.org>
8497 * get.c: Turned off debugging.

8514 (internal_cmd_frequencies) Doesn't handle extensions. Doesn't
8515 calculate `min_n', `max_degree'.
8516 (postcalc) Passes new arg to dump_statistics().
8517 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
8519 (dump_condensed) Adds variable name title.
8520 (sum_freqs) Removed.
8521 (calc_stats) Updated calculation algorithm.

8543 for non-weighted active files. Implemented some options.
8544 Finished polishing output format. Comment fixes. Merged

8555 descriptives_proc structure.
8556 (calc) Moved here from `descript.g'. Rewritten to calculate
8557 statistics via `moments about the mean' rather than by summing,
8558 summing squares, summing cubes, and so on.
8559 (postcalc) Rewritten for new-style statistical calculation.
8560 (display) Removed support for displaying variables across rows.
8561 No longer crushes the descriptives table. Removed ancient code.
8562 Added display of N, by variable and listwise.
8564 * descript.g: Removed; merged into `descript.q'.
8566 * expr-evl.c: (evaluate_expression) Now returns a double. For
8567 numeric results, it returns the result as well as storing it in
8568 the passed `value' structure if non-NULL. For string results it
8569 just returns 0.0 and it must be passed non-NULL. Many references
8570 to this function were optimized by use of this change, especially
8571 but not exclusively in `compute.c'.
8573 * frequencies.g: Comment fix.
8575 * glob.c: (glob var process_if_expr) New global var.

8587 (sfm_write_case) Increments `n_cases'.
8588 (sfm_close) Attempts to seek the system file back to the header
8589 and write the number of cases in its proper slot.
8591 * som-frnt.c: (som_insert_table) Masks off expansion options since
8592 only SOPT_X_NORM seems to work sensibly.
8594 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
8595 with a `fixed' value of 2.
8597 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
8599 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10

8615 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
8616 doesn't have to take into account number of value labels since
8617 they're in a subtable anyway. Also, doesn't display more than 10
8618 value labels since we can't yet break pages in subtables.
8620 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
8622 * som-frnt.c: (som_change_table_size) Simple change for elegance
8623 that shouldn't change behavior.
8624 (som_set_value) Comment fix.
8626 * som-high.c: (som_submit_table) Message fix.

8652 (read_variables) Proper cleanup on lossage.
8654 * sfm.h: (struct sfm_read_info) New struct for use by
8655 sfm_read_dictionary().
8657 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
8658 currently used just for tables that can be dynamically resized and
8659 thus have to be allocated with arena_malloc() instead of
8660 arena_alloc(). All references changed.
8661 (som_change_table_size) New function.
8662 (som_insert_table) Bugfix: now inserts `cell', not `c'!

8930 (output_record) Removed debug code.
8931 (merge) Added code to close all the input files that are currently
8932 open. This is a likely location for bugs, because I'm not sure
8933 about boundary conditions. Removed an unnecesary heap_delete().
8934 (merge_once) Removed input file "optimization" that in fact
8935 screwed up the rest of the code. Message and comment fixes.

8939 * error.c: [__CHECKER__] (induce_segfault) Flushes output streams.

10695 Sun Jul 14 15:45:31 1996 Ben Pfaff <blp@gnu.org>
10697 * Many more changes to som.c especially, but these will not be
10698 documented as I have resolved to remove them. This patchlevel is
10699 being released solely so that I can fall back to it if I decide
10700 that removing the changes is not a good idea.
10702 Sat Jul 13 09:58:44 1996 Ben Pfaff <blp@gnu.org>
10704 * som.c: (global var som) New member `cum_y'.

10769 frequencies.q, list.q, vars-prs.c, vfm.c: Removed reference to
10770 HAVE_MALLOC_H because Borland C++ alloca() is broken, so why

10805 * Thanks to an unreliable IDE hard drive, I have spent the last
10806 day reconstructing my Debian GNU/Linux installation and redoing
10807 the previous day's changes--somehow I managed to save every file
10808 except for output.c and output.h. So the following changes could
10809 really be considered independent of the output.c, output.h changes
10812 * output.h, output.c: Moved the outp_configure_vec global var,
10813 outp_names struct, and enum set OUTP_S_* from output.h to output.c.

10816 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
10818 * The entire philosophy behind configuration of the output drivers
10819 changed. Now there is a termcap-type configuration where drivers
10820 to be read are determined beforehand, rather than parsing the
10821 entire output init file and storing it in memory & deciding what
10822 to actually use later. Faster & more memory-efficient at the same
10825 * output.c: Comment fix. Removed outp_init_drivers global var.
10826 Removed all references to synonyms. New structure outp_defn. New
10827 global vars outp_macros, outp_configure_vec.

10837 (outp_list_classes) Bug fix, cleaned up.
10838 (outp_list_drivers) Not implemented anymore.

10853 * cmdline.c: (parse_command_line) New option -v --verbose;
10854 --version changed to -V. --device option changed syntax to just
10855 take a single device name. Accepts key=value declaration of
10856 output init file macros. Syntax message updated.

10862 overridden by real environment vars.
10863 (search_path) Uses verbose_msg() instead of #ifdef'd printf().
10864 * filename.h: interp_environ_vars() renamed interp_vars().
10866 * error.c, error.h: Added extern variable `verbosity', message
10869 * error.c: (vmsg) Support message class MM.

10874 (dump_z_table) Bug fix in column headers.
10876 * ascii.c: (ascii_init_driver) Changed minimum number of lines per
10877 page from 29 to 15. Don't set a default for ops[OPS_INIT,
10878 OPS_DONE]. Writes the uninit string when the driver is closed.
10879 (ascii_open_page) Write the init string before the first page.
10880 (output_shorts) Form of main loop changed from `while' to `for'.
10881 Bug fix with overstrikes: the character is printed *after* the
10882 backspace. Eliminated a lot of `& 0xff' modifiers.
10883 (advance_to_left_margin) New function.
10884 (return_carriage, output_lines) Handle left margin.
