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

390 positive and negative numeric constants.
391 (lex_double_p) Renamed lex_is_number(). Changed return type to

441 but fixed the real problem that was preventing the build from a
442 separate directory. I liked it my way better ;-)
444 Thu Mar 3 23:17:51 2005 Ben Pfaff <blp@gnu.org>
446 * expressions/parse.c: (expr_parse) Fix parameter type. Thanks to

710 (merge_once) Fix plenty of stupid mistakes.
712 Sat Jan 8 23:55:27 2005 Ben Pfaff <blp@gnu.org>
714 * casefile.c: (casefile_sleep) Need to flush_buffer() after
715 calling casefile_to_disk() or we will lose the last block in the
716 file if the casefile started out as disk-based.
717 (casefile_get_reader) Initialize reader->destructive to 0.
718 (cmd_debug_casefile) Add new test pattern.

756 * pfm-read.c: (read_variables) Remove direct manipulation of
757 v->aux, which is no longer needed. Fixes PR 11483.
759 Sat Jan 1 19:01:16 WST 2005 John Darrington <john@darrington.wattle.id.au>
761 * data-list.c Fixed a bug in parsing delimiters.

766 * percentiles.c Properly handled calculation of Tukey hinges where
767 the number of data is small.
769 * oneway.q Used the generic value_to_string function for independent

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

840 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
842 * var-labs.c (var_to_string) Now returns null if the variable is null
844 * value-labels.c (value_to_string) Made it return null if either the
845 value or the variable is null.
847 * hash.c (hsh_clear) Fixed a buglet.

866 Adopt GSL random number generators, paving the way for providing
867 the complete suite of random number generators on expressions.
869 * Makefile.am: Remove random.c, random.h.
875 * algorithm.c: (algo_default_random) Use GSL functions.
877 * casefile.c: (test_casefile) Use GSL RNG functions.
879 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
882 * sample.c: (cmd_sample) Use GSL RNG functions.

904 * permissions.c command.def Added the PERMISSIONS command
906 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
908 * q2c.c: (dump_header) Don't try to emit #includes at very top of
909 output file because that will precede #include <config.h>, which
911 (main) Add needed headers to /* (header) */ code.
913 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
915 Instead of making system or portable file readers responsible for
916 dropping and reordering variables, make them read full cases and
917 let the caller take care of any changes.
919 * get.c: New "case map" structure to handle this. Use for GET,
920 IMPORT, MATCH FILES. Essentially rewrite the whole file.
922 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
923 changed appropriately.
925 * sfm-read.c: (sfm_read_case) Ditto.
927 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
929 Decided that case_serialize() and case_unserialize() were too
930 abstract. Also we need a couple more functions to avoid excessive
931 copying for data in/out fast paths.
933 * case.c: (case_serial_size) Removed.
934 (case_serialize) Rename case_to_values() and make its argument
935 explicitly an array of union values.
936 (case_unserialize) Rename case_from_values() and make its argument
937 explicitly an array of union values.
938 (case_data_all) New function.
939 (case_data_all_rw) New function.
941 * casefile.c: (struct casefile) Change buffer from array of
942 unsigned char to array of union value for better accuracy.
943 Redefine buffer_used and buffer_size in terms of values, not
944 bytes. Remove case_size because it is now redundant with
945 value_cnt. Fix up all references to these members.
947 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
949 * barchart.c: (struct subcat) Make `label' member const to silence
950 GCC warning with -Wwrite-strings.
952 * cartesian.c: (struct dataset) Ditto.
954 * case.c: Don't re-define NDEBUG if already defined.
955 Add lots of comments.
957 * str.c: Fix includes.
959 * crosstabs.q: Fix includes.
961 * examine.q: Fix includes. Fix GCC warning about unused
964 * frequencies.q: (stat macro) Removed and replaced where used by
967 * list.q: Fix includes.
969 * oneway.q: Fix includes.
971 * piechart.c: Fix includes. Only define M_PI if not already
974 * sfm-read.c: (bswap) New function.
975 (bswap_int32) Write in terms of bswap.
978 * str.c: (ds_data) Add external definition here, needed because
979 str.h has only an `extern inline' version.
981 * value-labels.c: Fix includes.
983 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
985 Instead of providing a system or portable file writer with a raw
986 case in the format needed for output, provide it with a regular
987 case. The writer takes care of any needed translation.
989 * aggregate.c: Adopt new scheme for AGGREGATE.
990 (struct agr_proc) sfm_agr_case member removed.
991 (write_case_to_sfm) Removed because the new interface is easier to
994 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
996 * pfm-write.c: Implement new scheme.
998 * sfm-write.c: Ditto.
1000 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
1002 Instead of treating `struct file_handle' as a class to subclass
1003 into data files, system files, and portable files, instead use it
1004 as a helper that coordinates access. Now it is opaque, too.
1006 This means that most references to a struct file_handle are now
1007 changed into references to one of struct dfm_reader, struct
1008 dfm_writer, struct sfm_reader, struct sfm_writer, struct
1009 pfm_reader, or struct pfm_writer, according to what's being read
1012 Most related changes are only worth summarizing briefly.
1014 * dictionary.c: (dict_clear) Destroy aux data in deleted
1016 (dict_clear_aux) New function.
1017 (dict_create_var) Initialize aux, aux_dtor.
1018 (dict_delete_var) Destroy aux data in deleted variable.
1020 * file-handle.h: (struct fh_ext_class) Removed.
1021 (struct file_handle) Removed.
1022 (fh_init_files) Removed.
1024 * file-handle.q: Changed references to a handle's `private' member
1025 to direct references.
1026 (struct private_file_handle) Renamed file_handle.
1027 Add next, open_cnt, type, open_mode, aux members.
1028 (struct file_handle_list) Removed.
1029 (extern var inline_file) Removed.
1030 (static var file_handles) Changed from file_handle_list * to
1032 (create_file_handle) Initialize new members.
1033 (fh_close_handle) Removed.
1034 (mode_name) New function.
1035 (fh_open) New function.
1036 (fh_close) New function.
1037 (fh_parse_file_handle) Renamed fh_parse().
1039 * glob.c: (init_glob) Remove fh_init_files() call.
1041 * aggregate.c: use sfm_writer.
1042 (create_sysfile) Removed because the new interface is simpler.
1044 * apply-dict.c: Use sfm_reader.
1046 * data-list.c: Use dfm_reader.
1048 * file-type.c: Use dfm_reader.
1050 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
1052 * inpt-pgm.c: Use dfm_reader.
1054 * print.c: Use dfm_writer.
1056 * sysfile-info: Use sfm_reader.
1058 * dfm-read.c: Adopt new file handle infrastructure.
1060 * dfm-write.c: Ditto.
1062 * pfm-read.c: Ditto.
1064 * pfm-write.c: Ditto.
1066 * sfm-read.c: Ditto.
1068 * sfm-write.c: Ditto.
1070 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
1072 Break dictionary functions into separate header file.
1074 * dictionary.h: New file.
1076 * var.h: Moved dict_*() functions to dictionary.h.
1078 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
1080 Get rid of procedure-specific union in struct variable, using
1081 instead a void * pointer and a destructor function.
1083 Most related changes are only worth brief summaries.
1085 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
1086 old p.crs member in struct variable.
1088 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
1089 of old p.frq member in struct variable.
1091 * histogram.c: (draw_histogram) Takes new freq_tab arg because
1092 it's no longer possible to grab this from var->p.frq.
1094 * piechart.c: (draw_piechart) Ditto.
1096 * group.c: (group_proc_get) New function.
1098 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
1105 * main.c: (execute_command) Clear aux data in default_dict after
1106 each command. (It's debatable whether this should be done.)
1108 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
1109 member in struct variable.
1111 * means.q: Get rid of integer mode, which is not included in
1112 recent SPSS and was the only code that wanted per-variable private
1115 * var.h: (struct crosstab_proc) Removed.
1116 (struct frequencies_proc) Removed.
1117 (struct list_proc) Removed.
1118 (struct get_proc) Removed.
1119 (struct means_proc) Removed.
1120 (struct matrix_data_proc) Removed.
1121 (struct match_files_proc) Removed.
1122 (lots of enums) Removed.
1123 (struct variable) Removed members `p', `get'. Add member
1126 * vars-atr.c: (var_attach_aux) New function.
1127 (var_detach_aux) New function.
1128 (var_clear_aux) New function.
1129 (var_dtor_free) New function.
1130 (discard_variables) Use NULL instead of inline_file.
1132 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
1134 * value-labs.c Fixed the implmentation of value_to_string, so
1135 that it properly handles alpha values.
1137 * oneway.q Changed instances where labels were being probed manually,
1138 to use the canonical {var,value}_to_string functions
1140 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
1142 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
1143 plots. Changed the API of the cartesian plot to be a much lower level
1146 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
1148 * examine.q Added some of the parametric calculations
1150 * factor_stats.[ch] Created
1152 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
1154 * examine.q Changed the definition of factors to be a composite, and
1155 dealt with the consequences.
1157 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
1159 * examine.q Fixed problem where examine wasn't dealing properly with
1162 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
1164 * oneway.q Fixed problem where oneway wasn't dealing properly with
1167 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
1169 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
1170 command which had settings didn't get the appropriate code
1173 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
1174 to convert variables/values to strings.
1176 * examine.q Added framework for the EXAMINE command.
1178 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
1180 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
1181 subcommand types. Changed frequencies.q to use it rather then the
1182 custom parser. Dealt with the consequences. Added a test for NTILES
1183 subcommand of frequencies.
1185 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
1187 * oneway.q Fixed up the behaviour when given missing values
1189 * levene.c oneway.q Fixed a buglet with the levene statistic and
1190 incorporated the levene test into the oneway command.
1192 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
1193 global scope, since they're only relevant to T-TEST
1195 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
1197 * group.c group.h group_proc.h levene.c oneway.q t-test.q
1199 Made the t-test more consistent
1200 with the way it handles groups. That is, it now uses a hash instead
1201 of an array of 2. Also, made the levene.c file independent of the
1202 implementation of the t-test. So now levene should be fine for both
1205 * Added an oneway.q file for one way anova
1207 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
1209 * descript.c: (cmd_descriptives) Remove harmless but bogus test in
1212 Mon May 31 20:45:24 2004 Ben Pfaff <blp@gnu.org>
1216 * data-list.c: (cmd_data_list) Free dls->delims on lossage.
1217 (data_list_trns_free) Free dls->delims.

1225 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
1227 Generalize casefiles to the extent that we can use them for
1228 sorting and other kinds of data transformations. Change cases to
1229 be copy-on-write to improve memory efficiency in common cases.
1230 Every access to a member of a `struct ccase' was changed to be a
1231 call to a case_*() function, especially case_data(), case_num(),
1232 case_str(), or case_data_rw(). Many instances of a local variable
1233 named "case_num" were changed to "case_idx" as a consequence.
1234 Many `struct ccase *' were changed to actual `struct ccase'
1235 because of copying semantics of cases. In several places there
1236 was a choice between updating debug code to work with the new ADTs
1237 or just deleting it because it was useless; I chose to delete it.
1239 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
1245 * aggregate.c: (struct agr_proc) Change type of `sort' to
1246 sort_criteria *. Add `break_vars', `break_var_cnt' members.

1259 * alloc.c: (out_of_memory) Make non-static.
1261 * alloc.h: Prototype out_of_memory().
1263 * casefile.c: Switched from a linked list in-memory representation
1264 to a two-level array-style representation. The linked list was
1265 appropriate when we could stick a header onto cases, but that's no
1266 longer the case. Also, the two-level array will allow for random
1267 in-memory access in case that's ever wanted. Also added the
1268 concept of a `destructive casereader', one that destroys cases in
1269 the underlying casefile as they are read out.
1270 (macro CASES_PER_BLOCK) New macro.
1271 (struct casefile) New members `value_cnt', `case_list_size',

1287 (call_posix_fadvise) Removed because posix_fadvise64 segfaults.
1288 Couldn't figure out why.
1289 (casefile_to_disk) Don't call call_posix_fadvise. Rewritten to
1290 deal with new and removed members.

1303 (casereader_destroy) Destroy reader's case.
1304 (test_casefile) Second arg is now a value count, all callers

1580 Sun May 30 18:31:48 2004 Ben Pfaff <blp@gnu.org>

1591 rid of pool support, which was largely unused. Rename lots of

1627 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
1629 We're abusing the current ASCII driver by telling it to allocate a
1630 9999-line, 9999-character page in the tests. This causes some
1631 systems to curl up and die because it allocates 20 MB of
1632 contiguous RAM. This change alleviates at least part of the
1633 problem. It is mostly a stop-gap until the new output system is
1636 * ascii.c: (struct line) New structure.
1637 (struct ascii_driver_ext) Remove `page', `page_size', `line_len',
1638 `line_len_size', `n_output' members. Add `lines', `lines_cap'.
1639 (ascii_preopen_driver) Initialize new members, not old ones.

1657 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>
1659 Contrary to what I'd always understood, there is an efficient
1660 algorithm for deletion from a hash table populated via linear
1661 probing. This change implements it.

1665 (locate_matching_entry) Ditto.

1671 avoid subtracting huge numbers from huge numbers, on Michael
1674 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
1676 Rework moments routines for improved numerical stability based on
1677 Michael Kiefte's advice. Any bugs or remaining numerical problems
1678 are still mine though.
1680 There is now a struct moments1 for use with one-pass moments. It
1681 uses a provisional means algorithm as an attempt to improve
1682 accuracy of higher moments. The older struct moments now only
1683 handles two-pass moments.
1685 * aggregate.c: Use moments1 instead moments.
1687 * descript.c: Revert previous change, which is no longer needed
1688 due to the moments revision.
1690 * moments.c: (calc_moments) New function for calculating variance,
1692 (moments_pass_one) Only accumulate weights bigger than zero.
1693 (moments_calculate) Allow calculating the mean on pass one, others
1694 require pass two. Implement in terms of calc_moments().
1695 (struct moments1) New structure.
1696 (init_moments1) New function.
1697 (moments1_clear) Ditto.
1698 (moments1_create) Ditto.

1713 * descript.c (calc_descriptives): Fix assert failure when only
1714 MOMENT_MEAN is needed.
1716 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
1720 fixed problem with parsing in match_statistic() causing
1721 "DESCRIPTIVE STAT=MEAN." to barf.
1723 "MEAN" is now default if "SORT" given without specification.
1725 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
1726 generally less forgiving of syntax errors: better to have it do
1727 nothing and type it in again then to not know what it actually did
1730 z-score transformation now checks score for user-missing values
1731 and checks std_dev for SYSMIS.

3507 wasn't difficult or interesting so the details won't be given.

3520 transformations, so that they know where to send their cases.
3521 It's a big kluge. Also kluge in END CASE.

3560 pref.h. Change use of __WIN32__, __MSDOS, __DJGPP__,
3561 __CYGWIN32__, __unix__, and unix not to assume that they're
3562 defined to a nonzero value. Change use of __attribute__ to use
3563 NO_RETURN or PRINTF_FORMAT instead.
3565 * alloc.h: Move definitions for local_alloc(), local_free() here
3566 from ../pref.h.orig and simplify.
3568 * expr-evl.c: Instead of working differently based on PAGED_STACK,

3650 Start working on a new output driver system, one that doesn't suck
3651 so much, by adding a "device-independent" output driver. The idea
3652 is to write out only a single output stream, then use separate
3653 processes to translate them into whatever formats we want. This
3654 is similar to how "groff" works with its various output drivers
3655 (grops, grotty, grodvi, ...).

4048 All references to above functions updated.
4050 * aggregate.c: (cmd_aggregate) Copy file label and documents from
4051 old dictionary to new by hand, because dict_create() can't do it
4052 itself. Use dict_set_documents(), dict_set_split_vars().
4054 * temporary.c: (cancel_temporary) Also set temp_dict to NULL after
4055 calling dict_destroy().

4081 dict_set_documents().
4083 * vars-atr.c: (discard_variables) Use dict_clear(default_dict),
4084 reset default_handle by hand. dict_clear() will clear vectors so
4085 there's no need for that by hand.
4087 * vfm.c: (close_active_file) Move call to finish_compaction()
4088 earlier, so that we can do the compaction as a single step using
4089 dict_compact_values(). Use dict_clear_vectors().
4090 (finish_compaction) Use dict_delete_var(), dict_compact_values().
4092 Some functions don't have replacements:

4106 * aggregate.c: Eliminate separation of weighted and unweighted
4107 case. It made the code too obscure and I doubt it was actually
4108 faster. Instead, all code uses the "weighted" code, because
4109 that's a generalization of the "unweighted" code.
4112 (parse_aggregate_functions) No need to set FWEIGHT.
4113 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
4114 (dump_aggregate_info) Ditto.

5412 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
5414 * aggregate.c (agr_00x_end_func): Increment number of cases in

5419 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
5421 Undefined behavior was invoked by referencing a freed pointer.

5446 free_aggregate_functions(), since that function already frees
5449 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
5451 A null pointer was dereferenced, causing a core dump, when
5452 PERCENTILES was specified on FREQUENCIES. This fixes the problem,

5479 struct pointing to it. The underlying problem is a lot bigger
5480 than this (see TODO) but this is a stopgap for the simple case at
5483 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
5485 Nested INCLUDEs didn't work. Fixed.

5497 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>

5505 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
5507 Comment parsing wasn't consistent with the rest of the code in its
5508 idea of where one command ends and another starts. This meant
5509 that sometimes commands would be mysteriously ignored. Thanks to
5510 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
5512 * command.c: (parse_cmd) Hand off comment parsing to new function
5513 skip_comment() in lexer.c.
5514 * lexer.c: (skip_comment) New function.
5516 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
5518 The TABLE subcommand on MATCH FILES worked only erratically at
5519 best. This fixes it. Thanks to Dr. Dirk Melcher
5520 <BZN-mdksh@t-online.de> for reporting this bug.
5522 * get.c: (mtf_compare_BY_values) When comparing string values, a
5523 difference of 1 is still a difference :-)
5524 (mtf_processing) Inverted TABLE reading logic fixed. Also don't

5539 CROSSTABS sometimes segfaulted when asked to output multiple
5540 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
5543 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
5544 are passed to output_pivot_table() for its use.
5545 (output_pivot_table) Instead of assuming the number of columns is
5546 constant, keep track with maxcols. In general mode, use maxcells
5547 to determine whether more matrix cells need to be allocated.
5549 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
5551 CROSSTABS didn't display value labels for column and row
5552 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
5555 * crosstabs.q: (table_value_missing) If the specified value has a
5556 value label for this variable, then show it instead of the raw
5558 (display_dimensions) Delegate display of value_labels to
5559 table_value_missing.
5561 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>

5564 <BZN-mdksh@t-online.de> for reporting this bug.
5566 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
5567 if the file isn't declared as binary.
5569 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
5571 MATCH FILES corrupted memory and dumped core on some syntax

5582 <BZN-mdksh@t-online.de> for reporting this bug.
5584 * get.c: (mtf_processing) Set unused records to system-missing,
5587 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>

5606 Hankin <hankin@rogue.consultco.com> for pointing this out.
5608 * filename.c: (open_file) Don't try to store stdin, stdout,
5609 stderr as part of an array, because that doesn't always work.
5611 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
5613 The SAVE procedure didn't save long string variables properly.
5614 Fixed by this patch. Thanks to Hankin
5615 <hankin@rogue.consultco.com> for this patch.
5617 * sfm-write.c: (write_variable) Fix off-by-one error in writing
5618 out variable pad records.
5620 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
5622 Previously, if PRINT SPACE were given a negative argument, it
5623 would report an error, then spin in an (almost) infinite loop.
5624 This fixes that behavior.
5626 * print.c: (print_space_trns_proc) After reporting a negative
5627 argument, set number of lines to print to 1.
5629 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
5631 SPSS 8.0 outputs some new record types in its system files, and it
5632 allows longer value labels. Accept these system files.
5634 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
5635 11 emitted by SPSS 8.0.
5637 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
5639 The LIST procedure was too conservative in allocating space for
5640 buffers, which caused a bug that only showed up with very long
5641 output variables. Thanks to Hankin <hankin@dunno.com> for this
5644 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
5646 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
5648 Typo meant string format specifiers weren't checked properly. I
5649 think that Hankin <hankin@dunno.com> sent me this report, but I'm
5650 willing to be corrected on this point.
5652 * format.c: (check_string_specifier) Fix obvious typo.
5654 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>

5662 * expr-opt.c: (dump_node) OP_CASENUM is acceptable.
5664 Tue Jan 5 12:47:48 1999 Ben Pfaff <blp@gnu.org>
5666 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
5667 other behavior, *sigh*. This patch hopefully fixes that. This
5668 time I've actually tested it.
5670 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
5672 * data-list.c: (read_from_data_list_free,
5673 read_from_data_list_list) Call parse_string_as_format() directly
5674 without mucking around with the field width.
5676 Tue Jan 5 12:31:19 1999 Ben Pfaff <blp@gnu.org>
5678 Occasionally, you may encounter a script that wants to be
5679 interpreted in interactive mode. Make -i emulate this behavior to
5680 allow such scripts to be executed with PSPP.
5682 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
5684 * cmdline.c: (pre_syntax_message[]) Update -i description.
5686 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
5687 when -i is given on the command line) don't treat unindented lines
5688 as starting a new command.
5690 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
5692 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
5693 mostly caused by local initialized aggregates. After egcs is
5694 fixed upstream these can be removed, but for now they're not a big
5697 * ascii.c: (ascii_postopen_driver) Checker chokes on local
5698 initialized arrays. Avoid this.
5700 * sfm-write.c: (sfm_write_dictionary) Don't use a local
5703 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
5705 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
5706 following changes avoid. Currently I compile sources with egcs
5707 1.1.1 and gcc 2.7.2.3 before sending them out.
5709 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.
5711 * ascii.c: (option_tab[]) Initialize all struct members.

5740 Thu Nov 19 12:32:45 1998 Ben Pfaff <blp@gnu.org>
5742 * data-in.c: Examined each of the parsing functions to make sure
5743 that they wouldn't dump core if they were passed a string of the
5744 wrong length, since now the DATA LIST FREE/LIST routines don't
5745 check for field width before passing it to the data parser.
5746 (parse_RBHEX, parse_AHEX) Reject odd length input.
5747 (parse_string_as_format) Reject input that's too short or too
5750 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad
5751 a field to its entire declared output width then pass it to the
5752 data-in parsing routines. This contradicted the documented
5753 behavior. This is fixed in these changes. Thanks to Mark H. Wood
5754 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
5755 free-format parsing that differed from SPSS.
5756 (cut_field) Commas and spaces are treated identically. Returns
5757 the proper column instead of a fixed 1 value.
5758 (parse_field) Removed.
5759 (read_from_data_list_free, read_from_data_list_list) Call
5760 parse_string_as_format directly instead of parse_field.

5804 * main.c: (dump_token) Make kwtab[] const.
5806 * set.q: Spelling, comment fixes.

5811 * vars-prs.c: (fill_all_vars) Style fix.
5813 * vfm.c: (index_to_varname) Return const.
5815 Tue Aug 4 23:49:23 1998 Ben Pfaff <blp@gnu.org>
5817 * Changes in many source files for partial -ansi -pedantic and

5846 * getline.c: (getl_read_line) I18n fix.
5848 * lexer.h: Don't use gcc features if __STRICT_ANSI__.

5891 Sun Jul 5 00:17:25 1998 Ben Pfaff <blp@gnu.org>
5893 * Several source files: Removed some PORTME notes when reflection
5894 revealed that ANSI forbids that sort of breakage. Also, added
5895 lots of `unused' qualifiers here and there.
5897 * aggregate.c: (accumulate_aggregate_info) Remove local var
5898 weighting that turned out not to be used.

9061 * cmdline.c: Comment fixes.
9062 (pick_compat) Changed return type to int. Now, instead of setting
9063 glob var `compat' to the emulation, returns the emulation. All
9065 (parse_command_line) Added terminating null to end of
9066 `long_options' array definition.
9067 (pre_syntax_message) Fixes.
9068 (usage) Shows the default emulation in the syntax message by

9095 Fri May 9 16:53:52 1997 Ben Pfaff <blp@gnu.org>
9097 * getline.c: [!HAVE_LIBREADLINE] (read_console) Changed
9098 blp_getline() to getline().

9121 text_get_font_position method. All references deleted.
9123 * postscript.c: Big change here. Fontmaps were completely
9124 eliminated because of a change in philosophy. Comment fixes.
9125 (struct ps_fontmap, ps2dit_map, font_family, dit2family_map)
9127 (struct ps_driver_ext) `position', `fontmap', `prop_name',

9130 (static var ps_fontmaps) Removed.
9132 (ps_init_driver) Removed obsolete references, updated.
9133 Initializes `translate_x', `translate_y', `scale'. Doesn't read
9134 fontmap, of course. Refers to font names through internal_name
9135 rather than subversive means. Frees proper items.
9136 (static var option_tab[]) Removed `fontmap-file' option; renamed
9137 `fixed-font', `prop-font'.
9138 (ps_option) Corresponds to option_tab[].
9139 (read_fontmap, release_fontmap, ps_to_dit, compare_ps2dit,
9140 hash_ps2dit, compare_dit2family, hash_dit2family, compare_family,
9141 hash_family) Removed.
9142 (postopen) Generates font names from family names. Gets
9143 PostScript font name properly. New prologue file comment `!!!'
9145 (ps_open_page) Adds translate_x, translate_y to BP prologue
9146 function; gives SF argument floating-point format.
9147 (ps_text_set_font_by_name) Doesn't try to map PostScript->Groff
9148 font name. Doesn't change font family.
9149 (ps_text_set_font_by_position) Generates Groff font name from font
9150 family name instead of through table lookup.
9151 (ps_text_set_font_by_family) Renamed `ps_text_set_font_family',
9152 all references changed. Reduced to simple string assignment.
9153 (ps_get_font_name) Removed.
9154 (ps_get_font_family) Reduced to string return.
9155 (text) Doesn't save `position' since it no longer exists. Ugly
9156 kluge to save font family--fix soon?
9157 (load_font) Removed PostScript name argument.
9159 Thu May 1 14:58:59 1997 Ben Pfaff <blp@gnu.org>
9161 * postscript.c: Comment fix.

9172 * command.c: Comment fix.
9173 (static var cmd_table[]) Re-enabled EVALUATE command.
9174 (parse_cmd) Lotsa comment fixes. Fixed infinite loop in parsing
9175 of comments in script files. Now more liberal on criteria for
9176 performing a state transition--if *anything* happened correctly,
9177 not just if *everything* happened correctly.
9179 * data-out.c: (convert_F) Comment fix. Why in the fsck does
9180 Checker segfault on formatting large numbers and why in the fsck
9181 hadn't I noticed this before?
9183 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
9185 * list.q: (cmd_list) Commented out the actual output routine
9186 because of various problems. Probably will abandon the idea of
9187 using the general `crushed tables' for the LIST procedure.
9189 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
9190 clearing it. Allocates a new var_by_name dictionary before trying
9191 to add members to it.
9193 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
9194 `sib'. Changed type of `node' argument.
9195 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
9197 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
9198 [DEBUGGING] Only deletes the variable from var_by_name if that var
9201 Fri Apr 18 16:48:41 1997 Ben Pfaff <blp@gnu.org>
9203 * Makefile.am: Added include files to SOURCES. Added
9204 frequencies.q to EXTRA_DIST. Removed include/ from INCLUDES. Now

9216 * display.c: Removed dead code.
9218 * list.q: Turn debugging on.
9219 (flush_table) New debug code.
9221 * sfm-read.c: (read_value_labels) malloc's the structure before
9222 trying to assign to its members.
9224 * sfm-write.c: Comment fix.
9226 * som-high.c: (som_submit_table) Sets som.t and som.d on each call
9228 (output_table) No arguments anymore--gets them through `som'
9229 global. New debug code. In crushed tables, now sets `htv' as
9230 well as `hv' to avoid bad confusion later.
9231 (dump_crush_page) New debug code.
9233 * som-low.c: (som_dump_crush_page) New debug code.
9235 Thu Mar 27 01:11:29 1997 Ben Pfaff <blp@gnu.org>
9237 All source files: Broke long lines into multiple lines.

9240 HOST_SYSTEM constant.
9242 * cmdline.c: (var syntax_message[]) Broke into
9243 pre_syntax_message[] and post_syntax_message[].
9244 (usage) Outputs both parts, separated by driver list.
9246 * error.h: Fixed broken formatting.
9248 * expr-opt.c: (str_search, str_rsearch) New functions.
9250 * misc.c: (blp_getdelim) Removed. All references changed to

9270 * sort.c: Includes "stat.h", not <sys/stat.h>.
9272 * str.c: (strcasecmp) Removed.
9274 * title.c: (cmd_document) Uses host_system var instead of
9275 HOST_SYSTEM constant.
9277 * version.c: Generated on-the-fly by the Makefile instead of being
9280 * str.h: Comment fixes. Doesn't substitute for missing memmove or
9282 [!HAVE_STRNCASECMP] Declares strncasecmp().
9284 * version.h: Removed stray character. Comment fixes.
9285 (vars host_system, build_system) New vars.
9287 Mon Mar 24 21:47:31 1997 Ben Pfaff <blp@gnu.org>
9289 * Most source files: Changed formatting of copyright notice; fixed
9290 FSF address; reformatted to better conform to GNU standards;
9291 comment fixes. Added markups to prevent GNU indent from messing
9292 up my beautiful formatting :-).
9294 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
9295 that GNU indent markups can be passed through without problems.
9297 Wed Feb 19 21:30:31 1997 Ben Pfaff <blp@gnu.org>
9299 * get.c: Turned off debugging.
9301 * glob.c: (init_glob) Turned on save-file compression by default.
9303 * sfm-write.c: (sfm_write_case) Fixed bug which resulted in less

9314 (macro frq_extensions) Removed.
9315 (static vars min_n, max_degree) Removed, all references removed.
9316 (internal_cmd_frequencies) Doesn't handle extensions. Doesn't
9317 calculate `min_n', `max_degree'.
9318 (postcalc) Passes new arg to dump_statistics().
9319 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
9321 (dump_condensed) Adds variable name title.
9322 (sum_freqs) Removed.
9323 (calc_stats) Updated calculation algorithm.
9324 (dump_statistics) Removed warning for too-few observations.

9332 * som-frnt.c: (som_set_value, som_set_float, som_set_text)
9333 Improved debug code.
9335 * var.h: (enum series frq_*) Removed Fiasco extensions.

9339 * command.c: Added PROCESS IF to command table.
9341 * Lots & lots of places, removed checks for NULLs preceding calls
9342 to free_expression(), which itself checks.
9344 * descript.q: Removed Fiasco extensions. Removed optimizations
9345 for non-weighted active files. Implemented some options.
9346 Finished polishing output format. Comment fixes. Merged
9348 (static vars n_glob_miss_list, n_glob_valid, n_glob_missing,
9349 max_degree, min_n) Removed.
9350 (macro dsc_extensions) Removed.
9351 (struct dsc_info_struct) Removed `min_n' member, all references
9353 (internal_cmd_descriptives) Removed calculation of min_n,

9356 (precalc) Eliminated redundancy. Updated for changes to
9357 descriptives_proc structure.
9358 (calc) Moved here from `descript.g'. Rewritten to calculate
9359 statistics via `moments about the mean' rather than by summing,
9360 summing squares, summing cubes, and so on.
9361 (postcalc) Rewritten for new-style statistical calculation.
9362 (display) Removed support for displaying variables across rows.
9363 No longer crushes the descriptives table. Removed ancient code.
9364 Added display of N, by variable and listwise.
9366 * descript.g: Removed; merged into `descript.q'.
9368 * expr-evl.c: (evaluate_expression) Now returns a double. For
9369 numeric results, it returns the result as well as storing it in
9370 the passed `value' structure if non-NULL. For string results it
9371 just returns 0.0 and it must be passed non-NULL. Many references
9372 to this function were optimized by use of this change, especially
9373 but not exclusively in `compute.c'.
9375 * frequencies.g: Comment fix.
9377 * glob.c: (glob var process_if_expr) New global var.
9379 * postscript.c: (static var option_tab[]) Corrected entry for

9388 (sfm_write_dictionary) Sets `n_cases' to 0.
9389 (sfm_write_case) Increments `n_cases'.
9390 (sfm_close) Attempts to seek the system file back to the header
9391 and write the number of cases in its proper slot.
9393 * som-frnt.c: (som_insert_table) Masks off expansion options since
9394 only SOPT_X_NORM seems to work sensibly.
9396 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
9397 with a `fixed' value of 2.
9399 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
9401 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10
9402 value labels; uses SOPT_NONE instead of SOPT_X_BOTH.

9405 (struct descriptives_proc) Removed `miss_noweight'; new members
9406 `X_bar', `M2', `M3', `M4', `min', `max'.

9415 * glob.c: (glob var err) Removed.
9417 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
9418 doesn't have to take into account number of value labels since
9419 they're in a subtable anyway. Also, doesn't display more than 10
9420 value labels since we can't yet break pages in subtables.
9422 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
9424 * som-frnt.c: (som_change_table_size) Simple change for elegance
9425 that shouldn't change behavior.
9426 (som_set_value) Comment fix.
9428 * som-high.c: (som_submit_table) Message fix.
9430 Wed Jan 22 21:54:00 1997 Ben Pfaff <blp@gnu.org>
9432 * command.c: Added SYSFILE INFO to command table.

9447 and ')' are not written to the output in strings as literals.
9449 * sfm-read.c: (sfm_read_dictionary) New argument.
9450 (read_header) New argument. Sets the information structure's
9451 values from the header information.

9453 bizarre Checker problem, I guess.
9454 (read_variables) Proper cleanup on lossage.
9456 * sfm.h: (struct sfm_read_info) New struct for use by
9457 sfm_read_dictionary().
9459 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
9460 currently used just for tables that can be dynamically resized and
9461 thus have to be allocated with arena_malloc() instead of
9462 arena_alloc(). All references changed.
9463 (som_change_table_size) New function.
9464 (som_insert_table) Bugfix: now inserts `cell', not `c'!
9466 * som-high.c: [GLOBAL_DEBUGGING] (check_table) Moved to som-low.c.
9467 (som_submit_table) [GLOBAL_DEBUGGING] Doesn't call check_table()
9470 * som-low.c: (draw_cell) Calls draw_table_cell() for SCON_TABLE

9473 question. All references changed.

11607 * Thanks to an unreliable IDE hard drive, I have spent the last
11608 day reconstructing my Debian GNU/Linux installation and redoing
11609 the previous day's changes--somehow I managed to save every file
11610 except for output.c and output.h. So the following changes could
11611 really be considered independent of the output.c, output.h changes
11614 * output.h, output.c: Moved the outp_configure_vec global var,
11615 outp_names struct, and enum set OUTP_S_* from output.h to output.c.
11616 outp_configure_vec is now static.
11618 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
11620 * The entire philosophy behind configuration of the output drivers
11621 changed. Now there is a termcap-type configuration where drivers
11622 to be read are determined beforehand, rather than parsing the
11623 entire output init file and storing it in memory & deciding what
11624 to actually use later. Faster & more memory-efficient at the same
11627 * output.c: Comment fix. Removed outp_init_drivers global var.
11628 Removed all references to synonyms. New structure outp_defn. New
11629 global vars outp_macros, outp_configure_vec.

11634 (outp_init) Much functionality moved into outp_read_devices.
11635 (outp_read_devices) Format of output init file changed; name of

11648 outp_names; new enum set OUTP_S_*; new global var
11649 outp_configure_vec; function prototypes for output.c exports
11652 * main.c: (main) Calls outp_read_devices() after parsing the
11655 * cmdline.c: (parse_command_line) New option -v --verbose;
11656 --version changed to -V. --device option changed syntax to just
11657 take a single device name. Accepts key=value declaration of

11676 (dump_z_table) Bug fix in column headers.
11678 * ascii.c: (ascii_init_driver) Changed minimum number of lines per
11679 page from 29 to 15. Don't set a default for ops[OPS_INIT,
11680 OPS_DONE]. Writes the uninit string when the driver is closed.
11681 (ascii_open_page) Write the init string before the first page.
11682 (output_shorts) Form of main loop changed from `while' to `for'.

11710 * ascii.c: (delineate) Keeps track of vertical position.
11711 (text_draw) No longer considers fully justified text an internal
11714 * output.h: New flag OUTP_T_VERT; other OUTP_T_ values changed.
