305 Sun Mar 6 17:07:20 2005 Ben Pfaff <blp@gnu.org>
307 When the lexer sees something like `-5' in the input, it has to
308 decide whether it's a negative numeric constant token or a '-'
309 token followed by a positive numeric constant token. It always
310 decides on the former, and then the parser can call
311 lex_negative_to_dash() if it wants the latter. However, this
312 doesn't work for the case of `-0', because negative zero is
313 (portably) indistinguishable from positive zero. So now we divide
314 T_NUM into two tokens, T_POS_NUM and T_NEG_NUM, to make the
315 distinction clear. This requires a little bit of extra effort,
316 because there were several references to T_NUM in the code base.
318 * lexer.c: (lex_get) Use T_NEG_NUM and T_POS_NUM to distinguish
319 positive and negative numeric constants.
320 (lex_double_p) Renamed lex_is_number(). Changed return type to
321 bool. Updated all relevant references to T_NUM to instead use

369 * expressions/PSPP_expressions.pm: Renamed it back to generate.pl
370 but fixed the real problem that was preventing the build from a
371 separate directory. I liked it my way better ;-)
373 Thu Mar 3 23:17:51 2005 Ben Pfaff <blp@gnu.org>
375 * expressions/parse.c: (expr_parse) Fix parameter type. Thanks to

601 * ascii.c cartesian.c casefile.c chart.h devind.c
602 examine.q frequencies.q
603 html.c output.h piechart.c plot-chart.c plot-hist.c
605 Integrated the chart rendering into the output stream
606 (currently only works for html).
608 Removed gratuitous use of ifndef NO_CHARTS, and replaced with
609 dummy-chart.c for compiling without charts.
611 * mkfile.[ch] Created.
613 * som.[ch] tab.[ch]: Changed name of som_table to som_entity
614 Added type element so we can tell if it's a chart or a table.
616 * chart.h examine.q piechart.c plot-chart.c plot-hist.c: changed the
617 API of charts to be more like that of tables.
619 Thu Jan 13 21:00:02 WST 2005 John Darrington <john@darrington.wattle.id.au>
621 * casefile.c main.c: Moved the SIGINT handler from casefile.c to

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

667 Wed Jan 5 21:23:31 2005 Ben Pfaff <blp@gnu.org>
669 * sort.c: (merge) Fix assertion for proper Huffman merge pattern:
670 0 == 1 modulo 1. See Knuth 5.4.9 (vol. 3, 2nd ed.,
671 pp. 361). Thanks to John Darrington <john@cellform.com.au> for

683 Mon Jan 3 17:44:37 2005 Ben Pfaff <blp@gnu.org>
685 * pfm-read.c: (read_variables) Remove direct manipulation of
686 v->aux, which is no longer needed. Fixes PR 11483.
688 Sat Jan 1 19:01:16 WST 2005 John Darrington <john@darrington.wattle.id.au>
690 * data-list.c Fixed a bug in parsing delimiters.
692 * group.c vars-atr.c Fixed buglet in hash/compare functions for alpha
695 * percentiles.c Properly handled calculation of Tukey hinges where
696 the number of data is small.
698 * oneway.q Used the generic value_to_string function for independent
699 variable instead of trying to do it ourselves.
701 * box-whisker.c Fixed a buglet which caused a crash if the number of
705 Fri Dec 31 16:47:45 WST 2004 John Darrington <john@darrington.wattle.id.au>

710 there's a small number of cases.
712 Wed Dec 29 08:18:08 WST 2004 John Darrington <john@darrington.wattle.id.au>
714 * percentiles.[ch] Added. Calculates percentiles and Tukey hinges

732 Added code to calculate sensible histogram ranges and limits.
734 Thu Dec 2 13:37:43 WST 2004 John Darrington <john@darrington.wattle.id.au>
736 * chart.h Updated to reflect many API changes.
738 * cartesian.c chart.c Moved the definitions of chart_write_{xy}scale from
739 cartesian.c and into chart.c
741 * factorstats.[ch] Added the histogram calculations

745 * frequencies.q examine.q histogram.c Reworked the API for
748 * piechart.c Revised the API for piecharts.
750 * var.h Moved the definitions of freq_tab and freq out of var.h

753 Tue Nov 30 21:10:20 2004 Ben Pfaff <blp@gnu.org>
755 * flip.c: (flip_file) Check for off_t separately from fseeko(),
758 Tue Nov 30 08:47:41 2004 Ben Pfaff <blp@gnu.org>
760 * flip.c: (flip_file) If fseeko() is not available, use long int
761 for off_t. Thanks to "Marshall DeBerry" <mdb@radix.net> for
762 reporting the problem.
764 Mon Nov 29 12:20:59 WST 2004 John Darrington <john@darrington.wattle.id.au>

769 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
771 * var-labs.c (var_to_string) Now returns null if the variable is null
773 * value-labels.c (value_to_string) Made it return null if either the
774 value or the variable is null.
776 * hash.c (hsh_clear) Fixed a buglet.
778 * examine.q factor_stats.[ch] Largely rewrote, because I'd started
779 with the wrong model.

793 Mon Nov 15 23:47:40 2004 Ben Pfaff <blp@gnu.org>
795 Adopt GSL random number generators, paving the way for providing
796 the complete suite of random number generators on expressions.
798 * Makefile.am: Remove random.c, random.h.
804 * algorithm.c: (algo_default_random) Use GSL functions.
806 * casefile.c: (test_casefile) Use GSL RNG functions.
808 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
811 * sample.c: (cmd_sample) Use GSL RNG functions.
812 (sample_trns_proc) Ditto.
814 * set.q: (static var set_seed) Removed.
815 (static var seed_flag) Removed.
816 (static var rng) New variable.
817 (aux_stc_custom_seed) No seed value anymore, don't print anything.
818 (stc_custom_seed) Use new seed functions.
819 (seed_is_set) Removed.
820 (get_rng) New function that composes the entire external
822 (set_rng) New function.

833 * permissions.c command.def Added the PERMISSIONS command
835 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
837 * q2c.c: (dump_header) Don't try to emit #includes at very top of
838 output file because that will precede #include <config.h>, which
840 (main) Add needed headers to /* (header) */ code.
842 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
844 Instead of making system or portable file readers responsible for
845 dropping and reordering variables, make them read full cases and
846 let the caller take care of any changes.
848 * get.c: New "case map" structure to handle this. Use for GET,
849 IMPORT, MATCH FILES. Essentially rewrite the whole file.
851 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
852 changed appropriately.
854 * sfm-read.c: (sfm_read_case) Ditto.
856 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
858 Decided that case_serialize() and case_unserialize() were too
859 abstract. Also we need a couple more functions to avoid excessive
860 copying for data in/out fast paths.
862 * case.c: (case_serial_size) Removed.
863 (case_serialize) Rename case_to_values() and make its argument
864 explicitly an array of union values.
865 (case_unserialize) Rename case_from_values() and make its argument
866 explicitly an array of union values.
867 (case_data_all) New function.
868 (case_data_all_rw) New function.
870 * casefile.c: (struct casefile) Change buffer from array of
871 unsigned char to array of union value for better accuracy.
872 Redefine buffer_used and buffer_size in terms of values, not
873 bytes. Remove case_size because it is now redundant with
874 value_cnt. Fix up all references to these members.
876 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
878 * barchart.c: (struct subcat) Make `label' member const to silence
879 GCC warning with -Wwrite-strings.
881 * cartesian.c: (struct dataset) Ditto.
883 * case.c: Don't re-define NDEBUG if already defined.
884 Add lots of comments.
886 * str.c: Fix includes.
888 * crosstabs.q: Fix includes.
890 * examine.q: Fix includes. Fix GCC warning about unused
893 * frequencies.q: (stat macro) Removed and replaced where used by
896 * list.q: Fix includes.
898 * oneway.q: Fix includes.
900 * piechart.c: Fix includes. Only define M_PI if not already
903 * sfm-read.c: (bswap) New function.
904 (bswap_int32) Write in terms of bswap.
907 * str.c: (ds_data) Add external definition here, needed because
908 str.h has only an `extern inline' version.
910 * value-labels.c: Fix includes.
912 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
914 Instead of providing a system or portable file writer with a raw
915 case in the format needed for output, provide it with a regular
916 case. The writer takes care of any needed translation.
918 * aggregate.c: Adopt new scheme for AGGREGATE.
919 (struct agr_proc) sfm_agr_case member removed.
920 (write_case_to_sfm) Removed because the new interface is easier to
923 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
925 * pfm-write.c: Implement new scheme.
927 * sfm-write.c: Ditto.
929 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
931 Instead of treating `struct file_handle' as a class to subclass
932 into data files, system files, and portable files, instead use it
933 as a helper that coordinates access. Now it is opaque, too.
935 This means that most references to a struct file_handle are now
936 changed into references to one of struct dfm_reader, struct
937 dfm_writer, struct sfm_reader, struct sfm_writer, struct
938 pfm_reader, or struct pfm_writer, according to what's being read
941 Most related changes are only worth summarizing briefly.
943 * dictionary.c: (dict_clear) Destroy aux data in deleted
945 (dict_clear_aux) New function.
946 (dict_create_var) Initialize aux, aux_dtor.
947 (dict_delete_var) Destroy aux data in deleted variable.
949 * file-handle.h: (struct fh_ext_class) Removed.
950 (struct file_handle) Removed.
951 (fh_init_files) Removed.
953 * file-handle.q: Changed references to a handle's `private' member
954 to direct references.
955 (struct private_file_handle) Renamed file_handle.
956 Add next, open_cnt, type, open_mode, aux members.
957 (struct file_handle_list) Removed.
958 (extern var inline_file) Removed.
959 (static var file_handles) Changed from file_handle_list * to
961 (create_file_handle) Initialize new members.
962 (fh_close_handle) Removed.
963 (mode_name) New function.
964 (fh_open) New function.
965 (fh_close) New function.
966 (fh_parse_file_handle) Renamed fh_parse().
968 * glob.c: (init_glob) Remove fh_init_files() call.
970 * aggregate.c: use sfm_writer.
971 (create_sysfile) Removed because the new interface is simpler.
973 * apply-dict.c: Use sfm_reader.
975 * data-list.c: Use dfm_reader.
977 * file-type.c: Use dfm_reader.
979 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
981 * inpt-pgm.c: Use dfm_reader.
983 * print.c: Use dfm_writer.
985 * sysfile-info: Use sfm_reader.
987 * dfm-read.c: Adopt new file handle infrastructure.
989 * dfm-write.c: Ditto.
993 * pfm-write.c: Ditto.
997 * sfm-write.c: Ditto.
999 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
1001 Break dictionary functions into separate header file.
1003 * dictionary.h: New file.
1005 * var.h: Moved dict_*() functions to dictionary.h.
1007 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
1009 Get rid of procedure-specific union in struct variable, using
1010 instead a void * pointer and a destructor function.
1012 Most related changes are only worth brief summaries.
1014 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
1015 old p.crs member in struct variable.
1017 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
1018 of old p.frq member in struct variable.
1020 * histogram.c: (draw_histogram) Takes new freq_tab arg because
1021 it's no longer possible to grab this from var->p.frq.
1023 * piechart.c: (draw_piechart) Ditto.
1025 * group.c: (group_proc_get) New function.
1027 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
1034 * main.c: (execute_command) Clear aux data in default_dict after
1035 each command. (It's debatable whether this should be done.)
1037 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
1038 member in struct variable.
1040 * means.q: Get rid of integer mode, which is not included in
1041 recent SPSS and was the only code that wanted per-variable private
1044 * var.h: (struct crosstab_proc) Removed.
1045 (struct frequencies_proc) Removed.
1046 (struct list_proc) Removed.
1047 (struct get_proc) Removed.
1048 (struct means_proc) Removed.
1049 (struct matrix_data_proc) Removed.
1050 (struct match_files_proc) Removed.
1051 (lots of enums) Removed.
1052 (struct variable) Removed members `p', `get'. Add member
1055 * vars-atr.c: (var_attach_aux) New function.
1056 (var_detach_aux) New function.
1057 (var_clear_aux) New function.
1058 (var_dtor_free) New function.
1059 (discard_variables) Use NULL instead of inline_file.
1061 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
1063 * value-labs.c Fixed the implmentation of value_to_string, so
1064 that it properly handles alpha values.
1066 * oneway.q Changed instances where labels were being probed manually,
1067 to use the canonical {var,value}_to_string functions
1069 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
1071 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
1072 plots. Changed the API of the cartesian plot to be a much lower level
1075 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
1077 * examine.q Added some of the parametric calculations
1079 * factor_stats.[ch] Created
1081 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
1083 * examine.q Changed the definition of factors to be a composite, and
1084 dealt with the consequences.
1086 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
1088 * examine.q Fixed problem where examine wasn't dealing properly with
1091 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
1093 * oneway.q Fixed problem where oneway wasn't dealing properly with
1096 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
1098 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
1099 command which had settings didn't get the appropriate code
1102 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
1103 to convert variables/values to strings.
1105 * examine.q Added framework for the EXAMINE command.
1107 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
1109 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
1110 subcommand types. Changed frequencies.q to use it rather then the
1111 custom parser. Dealt with the consequences. Added a test for NTILES
1112 subcommand of frequencies.
1114 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
1116 * oneway.q Fixed up the behaviour when given missing values
1118 * levene.c oneway.q Fixed a buglet with the levene statistic and
1119 incorporated the levene test into the oneway command.
1121 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
1122 global scope, since they're only relevant to T-TEST
1124 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
1126 * group.c group.h group_proc.h levene.c oneway.q t-test.q
1128 Made the t-test more consistent
1129 with the way it handles groups. That is, it now uses a hash instead
1130 of an array of 2. Also, made the levene.c file independent of the
1131 implementation of the t-test. So now levene should be fine for both
1134 * Added an oneway.q file for one way anova
1136 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
1138 * descript.c: (cmd_descriptives) Remove harmless but bogus test in
1141 Mon May 31 20:45:24 2004 Ben Pfaff <blp@gnu.org>
1145 * data-list.c: (cmd_data_list) Free dls->delims on lossage.
1146 (data_list_trns_free) Free dls->delims.
1148 * t-test.q: (tts_custom_pairs) Free vars.
1149 (ssbox_one_sample_init) Fix tab_vline() argument.
1150 (ssbox_independent_samples_init) Ditto.
1151 (trbox_paired_init) Ditto.
1152 (trbox_one_sample_init) Ditto.
1154 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
1156 Generalize casefiles to the extent that we can use them for
1157 sorting and other kinds of data transformations. Change cases to
1158 be copy-on-write to improve memory efficiency in common cases.
1159 Every access to a member of a `struct ccase' was changed to be a
1160 call to a case_*() function, especially case_data(), case_num(),
1161 case_str(), or case_data_rw(). Many instances of a local variable
1162 named "case_num" were changed to "case_idx" as a consequence.
1163 Many `struct ccase *' were changed to actual `struct ccase'
1164 because of copying semantics of cases. In several places there
1165 was a choice between updating debug code to work with the new ADTs
1166 or just deleting it because it was useless; I chose to delete it.
1168 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
1174 * aggregate.c: (struct agr_proc) Change type of `sort' to
1175 sort_criteria *. Add `break_vars', `break_var_cnt' members.
1176 Rename `vars' to `agr_vars', all references updated. Change
1177 `agr_case' to type `struct ccase'.
1178 (cmd_aggregate) Deal with new members. Use case_create(),
1179 sort_active_file_in_place(), sort_active_file_to_casefile().
1180 (agr_destroy) Deal with new members.
1181 (aggregate_single_case) Ditto.
1182 (dump_aggregate_info) Ditto.
1183 (initialize_aggregate_info) Ditto.
1184 (agr_to_active_file) Ditto.
1185 (presorted_agr_to_sysfile) Ditto.
1186 (sort_agr_to_sysfile) Removed.
1188 * alloc.c: (out_of_memory) Make non-static.
1190 * alloc.h: Prototype out_of_memory().
1192 * casefile.c: Switched from a linked list in-memory representation
1193 to a two-level array-style representation. The linked list was
1194 appropriate when we could stick a header onto cases, but that's no
1195 longer the case. Also, the two-level array will allow for random
1196 in-memory access in case that's ever wanted. Also added the
1197 concept of a `destructive casereader', one that destroys cases in
1198 the underlying casefile as they are read out.
1199 (macro CASES_PER_BLOCK) New macro.
1200 (struct casefile) New members `value_cnt', `case_list_size',
1201 `case_acct_size', `being_destroyed', `cases'. Removed `head',
1203 (struct casereader) Removed `cur'. Added `destructive', `c'.

1519 Update our string ADTs, struct string and struct len_string. Get
1520 rid of pool support, which was largely unused. Rename lots of

1556 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
1558 We're abusing the current ASCII driver by telling it to allocate a
1559 9999-line, 9999-character page in the tests. This causes some
1560 systems to curl up and die because it allocates 20 MB of
1561 contiguous RAM. This change alleviates at least part of the
1562 problem. It is mostly a stop-gap until the new output system is
1565 * ascii.c: (struct line) New structure.
1566 (struct ascii_driver_ext) Remove `page', `page_size', `line_len',
1567 `line_len_size', `n_output' members. Add `lines', `lines_cap'.

1586 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>
1588 Contrary to what I'd always understood, there is an efficient

1603 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
1605 Rework moments routines for improved numerical stability based on
1606 Michael Kiefte's advice. Any bugs or remaining numerical problems
1607 are still mine though.
1609 There is now a struct moments1 for use with one-pass moments. It
1610 uses a provisional means algorithm as an attempt to improve
1611 accuracy of higher moments. The older struct moments now only
1612 handles two-pass moments.
1614 * aggregate.c: Use moments1 instead moments.
1616 * descript.c: Revert previous change, which is no longer needed
1617 due to the moments revision.
1619 * moments.c: (calc_moments) New function for calculating variance,
1621 (moments_pass_one) Only accumulate weights bigger than zero.
1622 (moments_calculate) Allow calculating the mean on pass one, others
1623 require pass two. Implement in terms of calc_moments().
1624 (struct moments1) New structure.
1625 (init_moments1) New function.
1626 (moments1_clear) Ditto.
1627 (moments1_create) Ditto.

1642 * descript.c (calc_descriptives): Fix assert failure when only
1643 MOMENT_MEAN is needed.
1645 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
1649 fixed problem with parsing in match_statistic() causing
1650 "DESCRIPTIVE STAT=MEAN." to barf.
1652 "MEAN" is now default if "SORT" given without specification.
1654 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
1655 generally less forgiving of syntax errors: better to have it do
1656 nothing and type it in again then to not know what it actually did
1659 z-score transformation now checks score for user-missing values
1660 and checks std_dev for SYSMIS.
1662 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
1664 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:
1665 Changed dict_get_case_weight() to accept an additional int * flag
1666 to complain about system-missing, user-missing, zero, or negative
1667 weights and updated existing functions to pass int * to
1668 dict_get_case_weight().
1670 2004-04-05 jmd <jmd@gnu.org>
1672 * main.c: Fixed configuration problems with gsl
1674 * t-test.q: Fixed some problems encountered when compiling under Cygwin

1695 * Makefile.am: Added the --ansi flag and dealt with the
1696 consequences. Added some entries to PSPP_sources so that
1697 make distcheck would pass
1699 * cmdline.c: Added the --syntax and --algorithm options
1701 * q2c.c: Added an implicit /ALGORITHM subcommand to everything.
1703 Fri Apr 2 11:25:22 WAST 2004 John Darrington <john@darrington.wattle.id.au>
1705 * t-test.q, levene.c, levene.h Converted t-test (incl levene) to
1706 use the new multipass_split_... mechanism.
1708 Wed Mar 31 22:36:22 2004 Ben Pfaff <blp@gnu.org>
1710 * frequencies.q: (calc_stats) Use moments data structure and
1711 calc_seskew(), calc_sekurt() functions.
1713 * set.q main.c settings.h Added support for --syntax and --algorithm
1716 Tue Mar 30 22:04:19 2004 Ben Pfaff <blp@gnu.org>
1718 * vfm.c: Had to get last call to multipass_split_output() inside
1719 open_active_file()/close_active_file() pairing, so introduce new
1721 (internal_procedure) Move procedure() code here, except for calls
1722 to open_active_file() and close_active_file().

1725 (multipass_procedure_with_splits) Wrap open_active_file() and

2092 Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
2094 Changed DFM from open-at-first-access to explicit-open. Before,
2095 calling dfm_get_record() or dfm_put_record() would automatically
2096 open the file. Now, you have to call dfm_open_for_reading() or

2214 Fixed cmd_parse() so that it always skips past a full command
2215 name. A few special commands for which this would be bad get
2216 special treatment. This lets us drop code for skipping past the
2217 end of a command name in most cmd_*() functions. It's not worth
2218 listing all the commands affected.
2220 * command.c: (struct command) Remove `cmd' member, replace by
2221 `name' member, all references updated. Remove `word', `next',
2222 `skip_entire_name' members.

2278 * set.q: Implemented the SHOW command, and synced it to the existing
2281 Added a handler for SIGWINCH so that viewlength and viewwidth follow
2282 changes as the window size is changed.
2284 Added fallback to set viewlength and viewwidth from LINES and COLUMS

3434 through these arguments. In some cases this meant that the extra
3435 args had to be threaded through a couple of extra levels. This
3436 wasn't difficult or interesting so the details won't be given.

3449 transformations, so that they know where to send their cases.
3450 It's a big kluge. Also kluge in END CASE.

3489 pref.h. Change use of __WIN32__, __MSDOS, __DJGPP__,

3491 defined to a nonzero value. Change use of __attribute__ to use
3492 NO_RETURN or PRINTF_FORMAT instead.
3494 * alloc.h: Move definitions for local_alloc(), local_free() here
3495 from ../pref.h.orig and simplify.
3497 * expr-evl.c: Instead of working differently based on PAGED_STACK,

3579 Start working on a new output driver system, one that doesn't suck
3580 so much, by adding a "device-independent" output driver. The idea
3581 is to write out only a single output stream, then use separate
3582 processes to translate them into whatever formats we want. This
3583 is similar to how "groff" works with its various output drivers
3584 (grops, grotty, grodvi, ...).

3977 All references to above functions updated.
3979 * aggregate.c: (cmd_aggregate) Copy file label and documents from
3980 old dictionary to new by hand, because dict_create() can't do it
3981 itself. Use dict_set_documents(), dict_set_split_vars().
3983 * temporary.c: (cancel_temporary) Also set temp_dict to NULL after
3984 calling dict_destroy().

4014 there's no need for that by hand.
4016 * vfm.c: (close_active_file) Move call to finish_compaction()
4017 earlier, so that we can do the compaction as a single step using
4018 dict_compact_values(). Use dict_clear_vectors().

4035 * aggregate.c: Eliminate separation of weighted and unweighted
4036 case. It made the code too obscure and I doubt it was actually
4037 faster. Instead, all code uses the "weighted" code, because

4042 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
4043 (dump_aggregate_info) Ditto.

4605 (hsh_next_prime) Ditto.
4606 (next_power_of_2) New function.

4619 functions than the ones we had, and cleaned up the names to boot:
4621 * hash.c: (hashpjw_d) Removed.

4639 Made deletion possible, though slow:
4641 * hash.c: (locate_matching_entry) New function.
4642 (hsh_find) Use locate_matching_entry().

4648 * quicksort.c: New file implementing a sort routine with a
4649 interface better than qsort() because it passes a user-provided

4654 Fri Dec 12 13:31:58 2003 Ben Pfaff <blp@gnu.org>

5327 <BZN-mdksh@t-online.de> for reporting this bug.
5329 * aggregate.c: (parse_aggregate_functions) When setting the
5330 FSTRING bit, also allocate memory for the `string' member of
5332 (free_aggregate_functions) Free iter->string. Don't use the
5333 non-function bits when indexing the array of functions.
5334 [DEBUGGING] (debug_print) Don't use the non-function bits when
5335 indexing the array of functions.
5337 Sun May 30 00:00:54 1999 Ben Pfaff <blp@gnu.org>
5339 Under certain circumstances, the final case would be omitted from
5340 the results of an AGGREGATE operation. Fixed. Thanks to Dr. Dirk
5341 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
5343 * aggregate.c (agr_00x_end_func): Increment number of cases in
5344 sink before writing case. For streams that keep track of how many
5345 cases there are based on this value, this means that the last case
5346 will be read in on the next stream read.
5348 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
5350 Undefined behavior was invoked by referencing a freed pointer.
5352 * vfm.c (memory_stream_write): Free pointer *after* checking for

5367 * sort.c: (allocate_cases) Initialize i.
5369 Sat May 29 21:40:54 1999 Ben Pfaff <blp@gnu.org>
5371 Syntax errors in function descriptions on AGGREGATE caused core
5374 * aggregate.c (cmd_aggregate): Don't free agr_dict after calling
5375 free_aggregate_functions(), since that function already frees
5378 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
5380 A null pointer was dereferenced, causing a core dump, when
5381 PERCENTILES was specified on FREQUENCIES. This fixes the problem,
5382 but PSPP still doesn't calculate percentiles. Thanks to Regnor
5383 Jernsletten <rjernsle@eunet.no> for reporting this problem.
5385 * arena.c: (arena_malloc) If the arena hasn't been initialized

5403 Tue Mar 9 13:18:54 1999 Ben Pfaff <blp@gnu.org>
5405 SPLIT FILE with a string variable caused a core dump. Fixed.
5407 * vfm.c: If the variable is a string then make a temporary value
5408 struct pointing to it. The underlying problem is a lot bigger
5409 than this (see TODO) but this is a stopgap for the simple case at
5412 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
5414 Nested INCLUDEs didn't work. Fixed.
5416 * getline.c: (getl_include) Set first_line to NULL in allocated
5419 Tue Mar 9 13:13:46 1999 Ben Pfaff <blp@gnu.org>
5421 The MATCH FILES procedure set the values of variables not present
5422 to 0. It should have been SYSMIS. This is now fixed.
5424 * get.c: (mtf_delete_file_in_place) Replace 0.0 by SYSMIS.
5426 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>
5428 The REMARK command was too aggressive about skipping lines. It
5429 didn't like being the last command in a file.
5431 * command.c: (cmd_remark) Call get_entire_line() instead of
5434 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
5436 Comment parsing wasn't consistent with the rest of the code in its
5437 idea of where one command ends and another starts. This meant
5438 that sometimes commands would be mysteriously ignored. Thanks to
5439 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
5441 * command.c: (parse_cmd) Hand off comment parsing to new function
5442 skip_comment() in lexer.c.
5443 * lexer.c: (skip_comment) New function.
5445 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
5447 The TABLE subcommand on MATCH FILES worked only erratically at
5448 best. This fixes it. Thanks to Dr. Dirk Melcher
5449 <BZN-mdksh@t-online.de> for reporting this bug.
5451 * get.c: (mtf_compare_BY_values) When comparing string values, a
5452 difference of 1 is still a difference :-)
5453 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
5454 advance TABLE files automatically when matched. Comment fixes.
5456 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>
5458 VARIABLE LABELS rejected a slash before the first variable

5462 * var-labs.c: (cmd_variable_labels) Ignore a leading slash in
5463 command specification.
5465 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>
5467 Because of an incorrect optimization in memory allocation,
5468 CROSSTABS sometimes segfaulted when asked to output multiple
5469 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
5472 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
5473 are passed to output_pivot_table() for its use.
5474 (output_pivot_table) Instead of assuming the number of columns is
5475 constant, keep track with maxcols. In general mode, use maxcells
5476 to determine whether more matrix cells need to be allocated.
5478 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
5480 CROSSTABS didn't display value labels for column and row
5481 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
5484 * crosstabs.q: (table_value_missing) If the specified value has a
5485 value label for this variable, then show it instead of the raw
5487 (display_dimensions) Delegate display of value_labels to
5488 table_value_missing.
5490 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
5492 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
5493 <BZN-mdksh@t-online.de> for reporting this bug.
5495 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
5496 if the file isn't declared as binary.
5498 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
5500 MATCH FILES corrupted memory and dumped core on some syntax
5503 * get.c: (cmd_match_files) Set file->handle to NULL before
5505 (mtf_free_file) Don't free a null dictionary.
5507 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
5509 MATCH FILES should set numeric values not available to the
5510 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
5511 <BZN-mdksh@t-online.de> for reporting this bug.
5513 * get.c: (mtf_processing) Set unused records to system-missing,
5516 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>
5518 KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
5519 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
5521 * temporary.c: (save_dictionary) Initialize var_by_name AVL tree
5522 in newly created dictionary, and add each copied variable to the

5529 * get.c: (trim_dictionary) Free variable list for KEEP after
5532 Mon Jan 18 12:57:36 1999 Ben Pfaff <blp@gnu.org>
5534 Some systems didn't like the way open_file was coded. Thanks to
5535 Hankin <hankin@rogue.consultco.com> for pointing this out.
5537 * filename.c: (open_file) Don't try to store stdin, stdout,
5538 stderr as part of an array, because that doesn't always work.
5540 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
5542 The SAVE procedure didn't save long string variables properly.
5543 Fixed by this patch. Thanks to Hankin
5544 <hankin@rogue.consultco.com> for this patch.
5546 * sfm-write.c: (write_variable) Fix off-by-one error in writing
5547 out variable pad records.
5549 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
5551 Previously, if PRINT SPACE were given a negative argument, it
5552 would report an error, then spin in an (almost) infinite loop.
5553 This fixes that behavior.
5555 * print.c: (print_space_trns_proc) After reporting a negative
5556 argument, set number of lines to print to 1.
5558 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
5560 SPSS 8.0 outputs some new record types in its system files, and it
5561 allows longer value labels. Accept these system files.
5563 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
5564 11 emitted by SPSS 8.0.
5566 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
5568 The LIST procedure was too conservative in allocating space for
5569 buffers, which caused a bug that only showed up with very long
5570 output variables. Thanks to Hankin <hankin@dunno.com> for this
5573 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
5575 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
5577 Typo meant string format specifiers weren't checked properly. I
5578 think that Hankin <hankin@dunno.com> sent me this report, but I'm
5579 willing to be corrected on this point.
5581 * format.c: (check_string_specifier) Fix obvious typo.
5583 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>

5595 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
5596 other behavior, *sigh*. This patch hopefully fixes that. This
5597 time I've actually tested it.
5599 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
5601 * data-list.c: (read_from_data_list_free,
5602 read_from_data_list_list) Call parse_string_as_format() directly

5607 Occasionally, you may encounter a script that wants to be
5608 interpreted in interactive mode. Make -i emulate this behavior to
5609 allow such scripts to be executed with PSPP.
5611 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
5613 * cmdline.c: (pre_syntax_message[]) Update -i description.
5615 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
5616 when -i is given on the command line) don't treat unindented lines

5619 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
5621 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
5622 mostly caused by local initialized aggregates. After egcs is
5623 fixed upstream these can be removed, but for now they're not a big
5626 * ascii.c: (ascii_postopen_driver) Checker chokes on local
5627 initialized arrays. Avoid this.
5629 * sfm-write.c: (sfm_write_dictionary) Don't use a local
5632 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
5634 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
5635 following changes avoid. Currently I compile sources with egcs
5636 1.1.1 and gcc 2.7.2.3 before sending them out.
5638 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.

5669 Thu Nov 19 12:32:45 1998 Ben Pfaff <blp@gnu.org>
5671 * data-in.c: Examined each of the parsing functions to make sure
5672 that they wouldn't dump core if they were passed a string of the

5675 (parse_RBHEX, parse_AHEX) Reject odd length input.
5676 (parse_string_as_format) Reject input that's too short or too
5679 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad

5681 data-in parsing routines. This contradicted the documented
5682 behavior. This is fixed in these changes. Thanks to Mark H. Wood
5683 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
5684 free-format parsing that differed from SPSS.

5822 * Several source files: Removed some PORTME notes when reflection
5823 revealed that ANSI forbids that sort of breakage. Also, added

8974 the declarations of macros taking arguments a lot nicer.
8976 Sun Jun 1 17:22:04 1997 Ben Pfaff <blp@gnu.org>
8978 * error.h: Removed CE, CW aliases for SE, SW.
8980 * q2c.c: Removed explicit streq() definition since it's duplicated
8983 * approx.h, error.h, font.h, hash.h, misc.h, output.h, somP.h,
8984 stats.h, str.h, tokens.h: Made the declarations of macros taking

8988 Sun Jun 1 12:02:06 1997 Ben Pfaff <blp@gnu.org>
8990 * cmdline.c: Comment fixes.
8991 (pick_compat) Changed return type to int. Now, instead of setting
8992 glob var `compat' to the emulation, returns the emulation. All
8994 (parse_command_line) Added terminating null to end of
8995 `long_options' array definition.
8996 (pre_syntax_message) Fixes.
8997 (usage) Shows the default emulation in the syntax message by
8998 calling pick_compat().
9000 * getline.c: (getl_add_include_dir) Separates paths with
9001 PATH_DELIMITER, not DIR_SEPARATOR.

9011 * ascii.c: Comment fixes.
9013 * output.c: (outp_get_paper_size)
9014 s/STAT_OUTPUT_INIT_FILE/STAT_OUTPUT_PAPERSIZE_FILE/.
9016 Sun May 25 22:34:07 1997 Ben Pfaff <blp@gnu.org>
9018 * ascii.c, postscript.c, sfm-read.c, sfm-write.c, sort.c: Include
9019 <errno.h>. GNU libc 2 enforces this!
9021 * command.c: (parse_cmd) Fixed problem with `else' clause being
9022 paired with wrong `if'. Comment fix.
9024 Fri May 9 16:53:52 1997 Ben Pfaff <blp@gnu.org>
9026 * getline.c: [!HAVE_LIBREADLINE] (read_console) Changed
9027 blp_getline() to getline().
9029 * output.c: (outp_eval_dimension) Changed the fix from last time;
9030 there was no variable `a'.
9032 * q2c.c: (get_line) Fixed boundary condition overrun bug.
9034 Mon May 5 21:58:22 1997 Ben Pfaff <blp@gnu.org>

9049 * output.h: (struct outp_class_struct) Removed
9050 text_get_font_position method. All references deleted.
9052 * postscript.c: Big change here. Fontmaps were completely
9053 eliminated because of a change in philosophy. Comment fixes.
9054 (struct ps_fontmap, ps2dit_map, font_family, dit2family_map)
9056 (struct ps_driver_ext) `position', `fontmap', `prop_name',
9057 `fixed_name' members removed. New members `prop_family',
9058 `fixed_family'. `family' member changed to type char *.
9059 (static var ps_fontmaps) Removed.
9061 (ps_init_driver) Removed obsolete references, updated.
9062 Initializes `translate_x', `translate_y', `scale'. Doesn't read
9063 fontmap, of course. Refers to font names through internal_name
9064 rather than subversive means. Frees proper items.
9065 (static var option_tab[]) Removed `fontmap-file' option; renamed
9066 `fixed-font', `prop-font'.
9067 (ps_option) Corresponds to option_tab[].
9068 (read_fontmap, release_fontmap, ps_to_dit, compare_ps2dit,
9069 hash_ps2dit, compare_dit2family, hash_dit2family, compare_family,
9070 hash_family) Removed.
9071 (postopen) Generates font names from family names. Gets
9072 PostScript font name properly. New prologue file comment `!!!'
9074 (ps_open_page) Adds translate_x, translate_y to BP prologue
9075 function; gives SF argument floating-point format.
9076 (ps_text_set_font_by_name) Doesn't try to map PostScript->Groff
9077 font name. Doesn't change font family.
9078 (ps_text_set_font_by_position) Generates Groff font name from font
9079 family name instead of through table lookup.
9080 (ps_text_set_font_by_family) Renamed `ps_text_set_font_family',
9081 all references changed. Reduced to simple string assignment.
9082 (ps_get_font_name) Removed.
9083 (ps_get_font_family) Reduced to string return.
9084 (text) Doesn't save `position' since it no longer exists. Ugly
9085 kluge to save font family--fix soon?
9086 (load_font) Removed PostScript name argument.
9088 Thu May 1 14:58:59 1997 Ben Pfaff <blp@gnu.org>
9090 * postscript.c: Comment fix.
9091 (ps_open_page) Puts scale factor in PostScript output.
9093 Sat Apr 26 11:49:32 1997 Ben Pfaff <blp@gnu.org>
9095 * Makefile.am: Distcleans q2c.

9099 * ascii.c: (delineate) Sets text size even if width is zero.
9101 * command.c: Comment fix.
9102 (static var cmd_table[]) Re-enabled EVALUATE command.
9103 (parse_cmd) Lotsa comment fixes. Fixed infinite loop in parsing
9104 of comments in script files. Now more liberal on criteria for
9105 performing a state transition--if *anything* happened correctly,
9106 not just if *everything* happened correctly.
9108 * data-out.c: (convert_F) Comment fix. Why in the fsck does
9109 Checker segfault on formatting large numbers and why in the fsck
9110 hadn't I noticed this before?
9112 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
9114 * list.q: (cmd_list) Commented out the actual output routine
9115 because of various problems. Probably will abandon the idea of
9116 using the general `crushed tables' for the LIST procedure.
9118 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
9119 clearing it. Allocates a new var_by_name dictionary before trying
9120 to add members to it.
9122 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
9123 `sib'. Changed type of `node' argument.
9124 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
9126 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
9127 [DEBUGGING] Only deletes the variable from var_by_name if that var
9130 Fri Apr 18 16:48:41 1997 Ben Pfaff <blp@gnu.org>
9132 * Makefile.am: Added include files to SOURCES. Added
9133 frequencies.q to EXTRA_DIST. Removed include/ from INCLUDES. Now
9134 includes rules for q2c. Added `boast' target.
9136 Fri Apr 18 15:42:22 1997 Ben Pfaff <blp@gnu.org>
9138 * Makefile.am: Maintainer-clean Makefile.in.
9140 * Makefile.am: Fixed redundant EXTRA_DIST line.
9142 * ascii.c: Comment fixes.
9143 (ascii_line_vert) Fixed overly aggressive range check.
9145 * display.c: Removed dead code.
9147 * list.q: Turn debugging on.
9148 (flush_table) New debug code.
9150 * sfm-read.c: (read_value_labels) malloc's the structure before
9151 trying to assign to its members.
9153 * sfm-write.c: Comment fix.
9155 * som-high.c: (som_submit_table) Sets som.t and som.d on each call
9157 (output_table) No arguments anymore--gets them through `som'
9158 global. New debug code. In crushed tables, now sets `htv' as
9159 well as `hv' to avoid bad confusion later.
9160 (dump_crush_page) New debug code.
9162 * som-low.c: (som_dump_crush_page) New debug code.
9164 Thu Mar 27 01:11:29 1997 Ben Pfaff <blp@gnu.org>
9166 All source files: Broke long lines into multiple lines.
9168 * ascii.c: (ascii_close_page) Uses host_system var in place of
9169 HOST_SYSTEM constant.
9171 * cmdline.c: (var syntax_message[]) Broke into
9172 pre_syntax_message[] and post_syntax_message[].
9173 (usage) Outputs both parts, separated by driver list.
9175 * error.h: Fixed broken formatting.
9177 * expr-opt.c: (str_search, str_rsearch) New functions.
9179 * misc.c: (blp_getdelim) Removed. All references changed to
9181 (str_search, str_rsearch) Removed.
9182 (memrmem) New function.
9184 * misc.h: (blp_getline) Removed. All reference changed to
9189 * filename.c: Includes "stat.h", not <sys/stat.h>.
9190 (blp_getenv) Uses host_system var instead of HOST_SYSTEM constant.
9192 * output.c: (outp_list_classes) Changed output formatting.

9195 HOST_SYSTEM constant.
9196 (write_rec_7_34) Extracts version numbers from the version string.
9199 * sort.c: Includes "stat.h", not <sys/stat.h>.
9201 * str.c: (strcasecmp) Removed.
9203 * title.c: (cmd_document) Uses host_system var instead of
9204 HOST_SYSTEM constant.
9206 * version.c: Generated on-the-fly by the Makefile instead of being
9209 * str.h: Comment fixes. Doesn't substitute for missing memmove or
9211 [!HAVE_STRNCASECMP] Declares strncasecmp().
9213 * version.h: Removed stray character. Comment fixes.
9214 (vars host_system, build_system) New vars.
9216 Mon Mar 24 21:47:31 1997 Ben Pfaff <blp@gnu.org>
9218 * Most source files: Changed formatting of copyright notice; fixed
9219 FSF address; reformatted to better conform to GNU standards;
9220 comment fixes. Added markups to prevent GNU indent from messing
9221 up my beautiful formatting :-).
9223 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
9224 that GNU indent markups can be passed through without problems.
9226 Wed Feb 19 21:30:31 1997 Ben Pfaff <blp@gnu.org>
9228 * get.c: Turned off debugging.
9230 * glob.c: (init_glob) Turned on save-file compression by default.
9232 * sfm-write.c: (sfm_write_case) Fixed bug which resulted in less

9243 (macro frq_extensions) Removed.
9244 (static vars min_n, max_degree) Removed, all references removed.
9245 (internal_cmd_frequencies) Doesn't handle extensions. Doesn't
9246 calculate `min_n', `max_degree'.
9247 (postcalc) Passes new arg to dump_statistics().
9248 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
9250 (dump_condensed) Adds variable name title.
9251 (sum_freqs) Removed.
9252 (calc_stats) Updated calculation algorithm.
9253 (dump_statistics) Removed warning for too-few observations.

9261 * som-frnt.c: (som_set_value, som_set_float, som_set_text)
9262 Improved debug code.
9264 * var.h: (enum series frq_*) Removed Fiasco extensions.

9271 to free_expression(), which itself checks.
9273 * descript.q: Removed Fiasco extensions. Removed optimizations
9274 for non-weighted active files. Implemented some options.
9275 Finished polishing output format. Comment fixes. Merged

9280 (struct dsc_info_struct) Removed `min_n' member, all references
9282 (internal_cmd_descriptives) Removed calculation of min_n,

9285 (precalc) Eliminated redundancy. Updated for changes to
9286 descriptives_proc structure.
9287 (calc) Moved here from `descript.g'. Rewritten to calculate
9288 statistics via `moments about the mean' rather than by summing,
9289 summing squares, summing cubes, and so on.
9290 (postcalc) Rewritten for new-style statistical calculation.
9291 (display) Removed support for displaying variables across rows.
9292 No longer crushes the descriptives table. Removed ancient code.
9293 Added display of N, by variable and listwise.
9295 * descript.g: Removed; merged into `descript.q'.
9297 * expr-evl.c: (evaluate_expression) Now returns a double. For
9298 numeric results, it returns the result as well as storing it in
9299 the passed `value' structure if non-NULL. For string results it
9300 just returns 0.0 and it must be passed non-NULL. Many references
9301 to this function were optimized by use of this change, especially
9302 but not exclusively in `compute.c'.
9304 * frequencies.g: Comment fix.
9306 * glob.c: (glob var process_if_expr) New global var.
9308 * postscript.c: (static var option_tab[]) Corrected entry for

9317 (sfm_write_dictionary) Sets `n_cases' to 0.
9318 (sfm_write_case) Increments `n_cases'.
9319 (sfm_close) Attempts to seek the system file back to the header
9320 and write the number of cases in its proper slot.
9322 * som-frnt.c: (som_insert_table) Masks off expansion options since
9323 only SOPT_X_NORM seems to work sensibly.
9325 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
9326 with a `fixed' value of 2.
9328 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
9330 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10

9344 * glob.c: (glob var err) Removed.
9346 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
9347 doesn't have to take into account number of value labels since
9348 they're in a subtable anyway. Also, doesn't display more than 10
9349 value labels since we can't yet break pages in subtables.
9351 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
9353 * som-frnt.c: (som_change_table_size) Simple change for elegance
9354 that shouldn't change behavior.
9355 (som_set_value) Comment fix.
9357 * som-high.c: (som_submit_table) Message fix.
9359 Wed Jan 22 21:54:00 1997 Ben Pfaff <blp@gnu.org>

9382 bizarre Checker problem, I guess.
9383 (read_variables) Proper cleanup on lossage.
9385 * sfm.h: (struct sfm_read_info) New struct for use by
9386 sfm_read_dictionary().
9388 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
9389 currently used just for tables that can be dynamically resized and
9390 thus have to be allocated with arena_malloc() instead of
9391 arena_alloc(). All references changed.
9392 (som_change_table_size) New function.
9393 (som_insert_table) Bugfix: now inserts `cell', not `c'!
9395 * som-high.c: [GLOBAL_DEBUGGING] (check_table) Moved to som-low.c.
9396 (som_submit_table) [GLOBAL_DEBUGGING] Doesn't call check_table()

9430 (parse_DTIME) Allows days not between 1 and 31.
9431 (parse_numeric) Makes local copy of f.type for easier usage.
9434 * data-out.c: (convert_F) When outputting as scientific, properly

9437 nitems. Changed strcpy to memcpy (no null terminator).
9438 (convert_date) Fixed FMT_JDATE: added 1900 to year.

9457 `n_rename' for clarity.
9458 (cmd_modify_vars) Initializes `forward' and `positional' at
9459 appropriate times. Frees lists of vars to rename on failure.

9476 non-NULL. Doesn't try to xstrdup() dictionary documents.
9477 Adapted so as to not irritate Checker.

9480 * title.c: (cmd_file_label) Doesn't skip FILE, LABEL tokens.
9481 (cmd_document) Doesn't skip DOCUMENT token. Adds some header
9482 lines to the document, indents the document. Also, it works now.

11428 * Many more changes to som.c especially, but these will not be
11429 documented as I have resolved to remove them. This patchlevel is
11430 being released solely so that I can fall back to it if I decide

11433 Sat Jul 13 09:58:44 1996 Ben Pfaff <blp@gnu.org>
11435 * som.c: (global var som) New member `cum_y'.

11481 (convert_F) Comment fix. Now won't print `-.000', etc.

11500 frequencies.q, list.q, vars-prs.c, vfm.c: Removed reference to
11501 HAVE_MALLOC_H because Borland C++ alloca() is broken, so why
11502 include the corresponding header?

11512 som_submission_form. Function prototypes revised.
11514 Outputting huge tables (1000s of rows) a few rows at a time
11515 is supported, though untested. May even break everything.
11516 Actually, the code doesn't even compile right now.

11534 Fri Jul 5 20:16:19 1996 Ben Pfaff <blp@gnu.org>
11536 * Thanks to an unreliable IDE hard drive, I have spent the last
11537 day reconstructing my Debian GNU/Linux installation and redoing
11538 the previous day's changes--somehow I managed to save every file
11539 except for output.c and output.h. So the following changes could
11540 really be considered independent of the output.c, output.h changes
11543 * output.h, output.c: Moved the outp_configure_vec global var,
11544 outp_names struct, and enum set OUTP_S_* from output.h to output.c.

11547 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
11549 * The entire philosophy behind configuration of the output drivers
11550 changed. Now there is a termcap-type configuration where drivers
11551 to be read are determined beforehand, rather than parsing the
11552 entire output init file and storing it in memory & deciding what
11553 to actually use later. Faster & more memory-efficient at the same
11556 * output.c: Comment fix. Removed outp_init_drivers global var.
11557 Removed all references to synonyms. New structure outp_defn. New
11558 global vars outp_macros, outp_configure_vec.

11567 (outp_clear) Renamed outp_done.
11568 (outp_list_classes) Bug fix, cleaned up.
11569 (outp_list_drivers) Not implemented anymore.
11570 (outp_configure_driver) Now a static function; simplified; now
11571 interpolates macros; supports new structure.

11574 (find_driver) First argument removed.
11576 * output.h: Global var outp_init_drivers removed; new structure
11577 outp_names; new enum set OUTP_S_*; new global var
11578 outp_configure_vec; function prototypes for output.c exports
11581 * main.c: (main) Calls outp_read_devices() after parsing the
11584 * cmdline.c: (parse_command_line) New option -v --verbose;
11585 --version changed to -V. --device option changed syntax to just
11586 take a single device name. Accepts key=value declaration of
11587 output init file macros. Syntax message updated.
11589 * filename.c: (expand_line) New function.
11590 (interp_environ_vars) Renamed interp_vars; no longer uses
11592 (blp_getenv) Allows $ARCH and $VER pseudo-environment-vars to be
11593 overridden by real environment vars.
11594 (search_path) Uses verbose_msg() instead of #ifdef'd printf().
