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

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

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

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

752 * percentiles.c Properly handled calculation of Tukey hinges where
753 the number of data is small.
755 * oneway.q Used the generic value_to_string function for independent
756 variable instead of trying to do it ourselves.
758 * box-whisker.c Fixed a buglet which caused a crash if the number of

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

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

852 Adopt GSL random number generators, paving the way for providing
853 the complete suite of random number generators on expressions.
855 * Makefile.am: Remove random.c, random.h.
861 * algorithm.c: (algo_default_random) Use GSL functions.
863 * casefile.c: (test_casefile) Use GSL RNG functions.
865 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,

890 * permissions.c command.def Added the PERMISSIONS command
892 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
894 * q2c.c: (dump_header) Don't try to emit #includes at very top of
895 output file because that will precede #include <config.h>, which
897 (main) Add needed headers to /* (header) */ code.
899 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
901 Instead of making system or portable file readers responsible for
902 dropping and reordering variables, make them read full cases and
903 let the caller take care of any changes.
905 * get.c: New "case map" structure to handle this. Use for GET,
906 IMPORT, MATCH FILES. Essentially rewrite the whole file.
908 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
909 changed appropriately.
911 * sfm-read.c: (sfm_read_case) Ditto.
913 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
915 Decided that case_serialize() and case_unserialize() were too
916 abstract. Also we need a couple more functions to avoid excessive
917 copying for data in/out fast paths.
919 * case.c: (case_serial_size) Removed.
920 (case_serialize) Rename case_to_values() and make its argument
921 explicitly an array of union values.
922 (case_unserialize) Rename case_from_values() and make its argument
923 explicitly an array of union values.
924 (case_data_all) New function.
925 (case_data_all_rw) New function.
927 * casefile.c: (struct casefile) Change buffer from array of
928 unsigned char to array of union value for better accuracy.
929 Redefine buffer_used and buffer_size in terms of values, not
930 bytes. Remove case_size because it is now redundant with
931 value_cnt. Fix up all references to these members.
933 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
935 * barchart.c: (struct subcat) Make `label' member const to silence
936 GCC warning with -Wwrite-strings.
938 * cartesian.c: (struct dataset) Ditto.
940 * case.c: Don't re-define NDEBUG if already defined.
941 Add lots of comments.
943 * str.c: Fix includes.
945 * crosstabs.q: Fix includes.
947 * examine.q: Fix includes. Fix GCC warning about unused
950 * frequencies.q: (stat macro) Removed and replaced where used by
953 * list.q: Fix includes.
955 * oneway.q: Fix includes.
957 * piechart.c: Fix includes. Only define M_PI if not already
960 * sfm-read.c: (bswap) New function.
961 (bswap_int32) Write in terms of bswap.
964 * str.c: (ds_data) Add external definition here, needed because
965 str.h has only an `extern inline' version.
967 * value-labels.c: Fix includes.
969 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
971 Instead of providing a system or portable file writer with a raw
972 case in the format needed for output, provide it with a regular
973 case. The writer takes care of any needed translation.
975 * aggregate.c: Adopt new scheme for AGGREGATE.
976 (struct agr_proc) sfm_agr_case member removed.
977 (write_case_to_sfm) Removed because the new interface is easier to
980 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
982 * pfm-write.c: Implement new scheme.
984 * sfm-write.c: Ditto.
986 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
988 Instead of treating `struct file_handle' as a class to subclass
989 into data files, system files, and portable files, instead use it
990 as a helper that coordinates access. Now it is opaque, too.
992 This means that most references to a struct file_handle are now
993 changed into references to one of struct dfm_reader, struct
994 dfm_writer, struct sfm_reader, struct sfm_writer, struct
995 pfm_reader, or struct pfm_writer, according to what's being read
998 Most related changes are only worth summarizing briefly.
1000 * dictionary.c: (dict_clear) Destroy aux data in deleted
1002 (dict_clear_aux) New function.
1003 (dict_create_var) Initialize aux, aux_dtor.
1004 (dict_delete_var) Destroy aux data in deleted variable.
1006 * file-handle.h: (struct fh_ext_class) Removed.
1007 (struct file_handle) Removed.
1008 (fh_init_files) Removed.
1010 * file-handle.q: Changed references to a handle's `private' member
1011 to direct references.
1012 (struct private_file_handle) Renamed file_handle.
1013 Add next, open_cnt, type, open_mode, aux members.
1014 (struct file_handle_list) Removed.
1015 (extern var inline_file) Removed.
1016 (static var file_handles) Changed from file_handle_list * to
1018 (create_file_handle) Initialize new members.
1019 (fh_close_handle) Removed.
1020 (mode_name) New function.
1021 (fh_open) New function.
1022 (fh_close) New function.
1023 (fh_parse_file_handle) Renamed fh_parse().
1025 * glob.c: (init_glob) Remove fh_init_files() call.
1027 * aggregate.c: use sfm_writer.
1028 (create_sysfile) Removed because the new interface is simpler.
1030 * apply-dict.c: Use sfm_reader.
1032 * data-list.c: Use dfm_reader.
1034 * file-type.c: Use dfm_reader.
1036 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
1038 * inpt-pgm.c: Use dfm_reader.
1040 * print.c: Use dfm_writer.
1042 * sysfile-info: Use sfm_reader.
1044 * dfm-read.c: Adopt new file handle infrastructure.
1046 * dfm-write.c: Ditto.
1048 * pfm-read.c: Ditto.
1050 * pfm-write.c: Ditto.
1052 * sfm-read.c: Ditto.
1054 * sfm-write.c: Ditto.
1056 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
1058 Break dictionary functions into separate header file.
1060 * dictionary.h: New file.
1062 * var.h: Moved dict_*() functions to dictionary.h.
1064 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
1066 Get rid of procedure-specific union in struct variable, using
1067 instead a void * pointer and a destructor function.
1069 Most related changes are only worth brief summaries.
1071 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
1072 old p.crs member in struct variable.
1074 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
1075 of old p.frq member in struct variable.
1077 * histogram.c: (draw_histogram) Takes new freq_tab arg because
1078 it's no longer possible to grab this from var->p.frq.
1080 * piechart.c: (draw_piechart) Ditto.
1082 * group.c: (group_proc_get) New function.
1084 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
1091 * main.c: (execute_command) Clear aux data in default_dict after
1092 each command. (It's debatable whether this should be done.)
1094 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
1095 member in struct variable.
1097 * means.q: Get rid of integer mode, which is not included in
1098 recent SPSS and was the only code that wanted per-variable private
1101 * var.h: (struct crosstab_proc) Removed.
1102 (struct frequencies_proc) Removed.
1103 (struct list_proc) Removed.
1104 (struct get_proc) Removed.
1105 (struct means_proc) Removed.
1106 (struct matrix_data_proc) Removed.
1107 (struct match_files_proc) Removed.
1108 (lots of enums) Removed.
1109 (struct variable) Removed members `p', `get'. Add member
1112 * vars-atr.c: (var_attach_aux) New function.
1113 (var_detach_aux) New function.
1114 (var_clear_aux) New function.
1115 (var_dtor_free) New function.
1116 (discard_variables) Use NULL instead of inline_file.
1118 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
1120 * value-labs.c Fixed the implmentation of value_to_string, so
1121 that it properly handles alpha values.
1123 * oneway.q Changed instances where labels were being probed manually,
1124 to use the canonical {var,value}_to_string functions
1126 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
1128 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
1129 plots. Changed the API of the cartesian plot to be a much lower level
1132 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
1134 * examine.q Added some of the parametric calculations
1136 * factor_stats.[ch] Created
1138 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
1140 * examine.q Changed the definition of factors to be a composite, and
1141 dealt with the consequences.
1143 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
1145 * examine.q Fixed problem where examine wasn't dealing properly with
1148 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
1150 * oneway.q Fixed problem where oneway wasn't dealing properly with
1153 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
1155 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
1156 command which had settings didn't get the appropriate code
1159 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
1160 to convert variables/values to strings.
1162 * examine.q Added framework for the EXAMINE command.
1164 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
1166 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
1167 subcommand types. Changed frequencies.q to use it rather then the
1168 custom parser. Dealt with the consequences. Added a test for NTILES
1169 subcommand of frequencies.
1171 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
1173 * oneway.q Fixed up the behaviour when given missing values
1175 * levene.c oneway.q Fixed a buglet with the levene statistic and
1176 incorporated the levene test into the oneway command.
1178 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
1179 global scope, since they're only relevant to T-TEST
1181 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
1183 * group.c group.h group_proc.h levene.c oneway.q t-test.q
1185 Made the t-test more consistent
1186 with the way it handles groups. That is, it now uses a hash instead
1187 of an array of 2. Also, made the levene.c file independent of the
1188 implementation of the t-test. So now levene should be fine for both
1191 * Added an oneway.q file for one way anova
1193 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
1195 * descript.c: (cmd_descriptives) Remove harmless but bogus test in

1211 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
1213 Generalize casefiles to the extent that we can use them for
1214 sorting and other kinds of data transformations. Change cases to
1215 be copy-on-write to improve memory efficiency in common cases.
1216 Every access to a member of a `struct ccase' was changed to be a
1217 call to a case_*() function, especially case_data(), case_num(),
1218 case_str(), or case_data_rw(). Many instances of a local variable
1219 named "case_num" were changed to "case_idx" as a consequence.
1220 Many `struct ccase *' were changed to actual `struct ccase'
1221 because of copying semantics of cases. In several places there
1222 was a choice between updating debug code to work with the new ADTs
1223 or just deleting it because it was useless; I chose to delete it.
1225 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
1231 * aggregate.c: (struct agr_proc) Change type of `sort' to
1232 sort_criteria *. Add `break_vars', `break_var_cnt' members.
1233 Rename `vars' to `agr_vars', all references updated. Change
1234 `agr_case' to type `struct ccase'.
1235 (cmd_aggregate) Deal with new members. Use case_create(),
1236 sort_active_file_in_place(), sort_active_file_to_casefile().

1247 * alloc.h: Prototype out_of_memory().
1249 * casefile.c: Switched from a linked list in-memory representation
1250 to a two-level array-style representation. The linked list was
1251 appropriate when we could stick a header onto cases, but that's no
1252 longer the case. Also, the two-level array will allow for random
1253 in-memory access in case that's ever wanted. Also added the
1254 concept of a `destructive casereader', one that destroys cases in
1255 the underlying casefile as they are read out.
1256 (macro CASES_PER_BLOCK) New macro.
1257 (struct casefile) New members `value_cnt', `case_list_size',

1274 Couldn't figure out why.
1275 (casefile_to_disk) Don't call call_posix_fadvise. Rewritten to
1276 deal with new and removed members.

1533 (close_writer) New function.
1534 (static var dfm_writer_ext) Use close_writer for destructor.
1535 (cmd_begin_data) Adapt to new dfm_reader_ext.

1564 undefined behavior for overlapping arguments.
1566 Sun May 30 18:31:48 2004 Ben Pfaff <blp@gnu.org>

1570 (call_posix_fadvise) New function.
1571 (casefile_to_disk) Use call_posix_fadvise().
1572 (reader_open_file) Ditto.
1574 Sun May 30 18:20:12 2004 Ben Pfaff <blp@gnu.org>
1576 Update our string ADTs, struct string and struct len_string. Get
1577 rid of pool support, which was largely unused. Rename lots of
1578 functions to have more obvious or consistent names.
1580 * ascii.c: Get rid of ascii_pool. It was only used for string
1582 (ascii_open_global) Don't create ascii_pool.

1613 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
1615 We're abusing the current ASCII driver by telling it to allocate a
1616 9999-line, 9999-character page in the tests. This causes some
1617 systems to curl up and die because it allocates 20 MB of
1618 contiguous RAM. This change alleviates at least part of the
1619 problem. It is mostly a stop-gap until the new output system is
1622 * ascii.c: (struct line) New structure.
1623 (struct ascii_driver_ext) Remove `page', `page_size', `line_len',
1624 `line_len_size', `n_output' members. Add `lines', `lines_cap'.
1625 (ascii_preopen_driver) Initialize new members, not old ones.

1639 * matrix.c: Dead code. Removed.
1641 * matrix.h: Dead code. Removed.
1643 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>
1645 Contrary to what I'd always understood, there is an efficient
1646 algorithm for deletion from a hash table populated via linear
1647 probing. This change implements it.
1649 * hash.c: (hsh_rehash) Probe in increasing order.
1651 (locate_matching_entry) Ditto.
1652 (hsh_delete) Use Knuth's Algorithm 6.4R for deletion.
1654 Tue Apr 13 19:24:15 2004 Ben Pfaff <blp@gnu.org>
1656 * moments.c (calc_moments): Adjust calculation of kurtosis to
1657 avoid subtracting huge numbers from huge numbers, on Michael
1660 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
1662 Rework moments routines for improved numerical stability based on
1663 Michael Kiefte's advice. Any bugs or remaining numerical problems
1664 are still mine though.
1666 There is now a struct moments1 for use with one-pass moments. It
1667 uses a provisional means algorithm as an attempt to improve
1668 accuracy of higher moments. The older struct moments now only
1669 handles two-pass moments.
1671 * aggregate.c: Use moments1 instead moments.
1673 * descript.c: Revert previous change, which is no longer needed
1674 due to the moments revision.
1676 * moments.c: (calc_moments) New function for calculating variance,
1678 (moments_pass_one) Only accumulate weights bigger than zero.
1679 (moments_calculate) Allow calculating the mean on pass one, others
1680 require pass two. Implement in terms of calc_moments().
1681 (struct moments1) New structure.
1682 (init_moments1) New function.
1683 (moments1_clear) Ditto.
1684 (moments1_create) Ditto.
1685 (moments1_add) Ditto.

1693 * Makefile.am (pspp_SOURCES): Remove debug.c.
1695 * debug.c: Removed. It was empty anyway.
1697 Fri Apr 9 20:04:49 2004 Ben Pfaff <blp@gnu.org>
1699 * descript.c (calc_descriptives): Fix assert failure when only
1700 MOMENT_MEAN is needed.
1702 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
1706 fixed problem with parsing in match_statistic() causing
1707 "DESCRIPTIVE STAT=MEAN." to barf.
1709 "MEAN" is now default if "SORT" given without specification.
1711 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
1712 generally less forgiving of syntax errors: better to have it do
1713 nothing and type it in again then to not know what it actually did
1716 z-score transformation now checks score for user-missing values
1717 and checks std_dev for SYSMIS.
1719 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
1721 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:
1722 Changed dict_get_case_weight() to accept an additional int * flag
1723 to complain about system-missing, user-missing, zero, or negative

2105 Fri Mar 26 00:08:38 2004 Ben Pfaff <blp@gnu.org>
2107 Added abort() after lots of assert(0) invocations to avoid some

2149 Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
2151 Changed DFM from open-at-first-access to explicit-open. Before,
2152 calling dfm_get_record() or dfm_put_record() would automatically
2153 open the file. Now, you have to call dfm_open_for_reading() or
2154 dfm_open_for_writing() explicitly. This makes it possible to
2155 check permissions, file existence, etc. earlier.
2157 Also made struct file_handle more opaque, and clean up in general.

2186 * file-handle.q: (struct private_file_handle) New structure.

2237 * matrix-data.c: (cmd_matrix_data) Open file for reading.
2239 * pfm-read.c: Use handle_get_filename() instead of trying to use
2240 h->fn directly, all over.
2242 * pfm-write.c: Ditto.

2271 Fixed cmd_parse() so that it always skips past a full command
2272 name. A few special commands for which this would be bad get
2273 special treatment. This lets us drop code for skipping past the
2274 end of a command name in most cmd_*() functions. It's not worth

3493 wasn't difficult or interesting so the details won't be given.

3548 defined to a nonzero value. Change use of __attribute__ to use
3549 NO_RETURN or PRINTF_FORMAT instead.
3551 * alloc.h: Move definitions for local_alloc(), local_free() here
3552 from ../pref.h.orig and simplify.
3554 * expr-evl.c: Instead of working differently based on PAGED_STACK,

3636 Start working on a new output driver system, one that doesn't suck
3637 so much, by adding a "device-independent" output driver. The idea
3638 is to write out only a single output stream, then use separate
3639 processes to translate them into whatever formats we want. This
3640 is similar to how "groff" works with its various output drivers
3641 (grops, grotty, grodvi, ...).

4034 All references to above functions updated.
4036 * aggregate.c: (cmd_aggregate) Copy file label and documents from
4037 old dictionary to new by hand, because dict_create() can't do it
4038 itself. Use dict_set_documents(), dict_set_split_vars().
4040 * temporary.c: (cancel_temporary) Also set temp_dict to NULL after
4041 calling dict_destroy().

4070 reset default_handle by hand. dict_clear() will clear vectors so
4071 there's no need for that by hand.
4073 * vfm.c: (close_active_file) Move call to finish_compaction()
4074 earlier, so that we can do the compaction as a single step using
4075 dict_compact_values(). Use dict_clear_vectors().

4078 Some functions don't have replacements:

4092 * aggregate.c: Eliminate separation of weighted and unweighted
4093 case. It made the code too obscure and I doubt it was actually
4094 faster. Instead, all code uses the "weighted" code, because
4095 that's a generalization of the "unweighted" code.
4098 (parse_aggregate_functions) No need to set FWEIGHT.
4099 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
4100 (dump_aggregate_info) Ditto.

5390 non-function bits when indexing the array of functions.
5391 [DEBUGGING] (debug_print) Don't use the non-function bits when
5392 indexing the array of functions.
5394 Sun May 30 00:00:54 1999 Ben Pfaff <blp@gnu.org>

5398 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
5400 * aggregate.c (agr_00x_end_func): Increment number of cases in
5401 sink before writing case. For streams that keep track of how many
5402 cases there are based on this value, this means that the last case

5405 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
5407 Undefined behavior was invoked by referencing a freed pointer.

5432 free_aggregate_functions(), since that function already frees
5435 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
5437 A null pointer was dereferenced, causing a core dump, when
5438 PERCENTILES was specified on FREQUENCIES. This fixes the problem,

5440 Jernsletten <rjernsle@eunet.no> for reporting this problem.
5442 * arena.c: (arena_malloc) If the arena hasn't been initialized

5462 SPLIT FILE with a string variable caused a core dump. Fixed.
5464 * vfm.c: If the variable is a string then make a temporary value
5465 struct pointing to it. The underlying problem is a lot bigger
5466 than this (see TODO) but this is a stopgap for the simple case at
5469 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
5471 Nested INCLUDEs didn't work. Fixed.

5483 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>

5491 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
5493 Comment parsing wasn't consistent with the rest of the code in its
5494 idea of where one command ends and another starts. This meant
5495 that sometimes commands would be mysteriously ignored. Thanks to
5496 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
5498 * command.c: (parse_cmd) Hand off comment parsing to new function
5499 skip_comment() in lexer.c.
5500 * lexer.c: (skip_comment) New function.
5502 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
5504 The TABLE subcommand on MATCH FILES worked only erratically at
5505 best. This fixes it. Thanks to Dr. Dirk Melcher
5506 <BZN-mdksh@t-online.de> for reporting this bug.
5508 * get.c: (mtf_compare_BY_values) When comparing string values, a
5509 difference of 1 is still a difference :-)
5510 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
5511 advance TABLE files automatically when matched. Comment fixes.
5513 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>

5520 command specification.
5522 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>

5525 CROSSTABS sometimes segfaulted when asked to output multiple
5526 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
5529 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
5530 are passed to output_pivot_table() for its use.
5531 (output_pivot_table) Instead of assuming the number of columns is
5532 constant, keep track with maxcols. In general mode, use maxcells
5533 to determine whether more matrix cells need to be allocated.
5535 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
5537 CROSSTABS didn't display value labels for column and row
5538 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
5541 * crosstabs.q: (table_value_missing) If the specified value has a
5542 value label for this variable, then show it instead of the raw
5544 (display_dimensions) Delegate display of value_labels to
5545 table_value_missing.
5547 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
5549 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
5550 <BZN-mdksh@t-online.de> for reporting this bug.
5552 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
5553 if the file isn't declared as binary.
5555 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
5557 MATCH FILES corrupted memory and dumped core on some syntax
5560 * get.c: (cmd_match_files) Set file->handle to NULL before
5562 (mtf_free_file) Don't free a null dictionary.
5564 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
5566 MATCH FILES should set numeric values not available to the
5567 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
5568 <BZN-mdksh@t-online.de> for reporting this bug.
5570 * get.c: (mtf_processing) Set unused records to system-missing,
5573 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>

5592 Hankin <hankin@rogue.consultco.com> for pointing this out.
5594 * filename.c: (open_file) Don't try to store stdin, stdout,
5595 stderr as part of an array, because that doesn't always work.
5597 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
5599 The SAVE procedure didn't save long string variables properly.
5600 Fixed by this patch. Thanks to Hankin
5601 <hankin@rogue.consultco.com> for this patch.
5603 * sfm-write.c: (write_variable) Fix off-by-one error in writing
5604 out variable pad records.

5608 Previously, if PRINT SPACE were given a negative argument, it
5609 would report an error, then spin in an (almost) infinite loop.
5610 This fixes that behavior.
5612 * print.c: (print_space_trns_proc) After reporting a negative
5613 argument, set number of lines to print to 1.
5615 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
5617 SPSS 8.0 outputs some new record types in its system files, and it
5618 allows longer value labels. Accept these system files.
5620 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
5621 11 emitted by SPSS 8.0.
5623 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
5625 The LIST procedure was too conservative in allocating space for
5626 buffers, which caused a bug that only showed up with very long
5627 output variables. Thanks to Hankin <hankin@dunno.com> for this
5630 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
5632 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
5634 Typo meant string format specifiers weren't checked properly. I
5635 think that Hankin <hankin@dunno.com> sent me this report, but I'm
5636 willing to be corrected on this point.
5638 * format.c: (check_string_specifier) Fix obvious typo.
5640 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>

5648 * expr-opt.c: (dump_node) OP_CASENUM is acceptable.
5650 Tue Jan 5 12:47:48 1999 Ben Pfaff <blp@gnu.org>
5652 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
5653 other behavior, *sigh*. This patch hopefully fixes that. This
5654 time I've actually tested it.
5656 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
5658 * data-list.c: (read_from_data_list_free,
5659 read_from_data_list_list) Call parse_string_as_format() directly
5660 without mucking around with the field width.
5662 Tue Jan 5 12:31:19 1999 Ben Pfaff <blp@gnu.org>
5664 Occasionally, you may encounter a script that wants to be
5665 interpreted in interactive mode. Make -i emulate this behavior to
5666 allow such scripts to be executed with PSPP.
5668 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
5670 * cmdline.c: (pre_syntax_message[]) Update -i description.
5672 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
5673 when -i is given on the command line) don't treat unindented lines
5674 as starting a new command.
5676 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
5678 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
5679 mostly caused by local initialized aggregates. After egcs is
5680 fixed upstream these can be removed, but for now they're not a big
5683 * ascii.c: (ascii_postopen_driver) Checker chokes on local
5684 initialized arrays. Avoid this.
5686 * sfm-write.c: (sfm_write_dictionary) Don't use a local
5689 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
5691 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
5692 following changes avoid. Currently I compile sources with egcs
5693 1.1.1 and gcc 2.7.2.3 before sending them out.
5695 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.
5697 * ascii.c: (option_tab[]) Initialize all struct members.

5726 Thu Nov 19 12:32:45 1998 Ben Pfaff <blp@gnu.org>
5728 * data-in.c: Examined each of the parsing functions to make sure
5729 that they wouldn't dump core if they were passed a string of the
5730 wrong length, since now the DATA LIST FREE/LIST routines don't
5731 check for field width before passing it to the data parser.
5732 (parse_RBHEX, parse_AHEX) Reject odd length input.
5733 (parse_string_as_format) Reject input that's too short or too
5736 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad
5737 a field to its entire declared output width then pass it to the
5738 data-in parsing routines. This contradicted the documented
5739 behavior. This is fixed in these changes. Thanks to Mark H. Wood
5740 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
5741 free-format parsing that differed from SPSS.
5742 (cut_field) Commas and spaces are treated identically. Returns
5743 the proper column instead of a fixed 1 value.
5744 (parse_field) Removed.
5745 (read_from_data_list_free, read_from_data_list_list) Call
5746 parse_string_as_format directly instead of parse_field.

5799 * vfm.c: (index_to_varname) Return const.
5801 Tue Aug 4 23:49:23 1998 Ben Pfaff <blp@gnu.org>
5803 * Changes in many source files for partial -ansi -pedantic and

5877 Sun Jul 5 00:17:25 1998 Ben Pfaff <blp@gnu.org>
5879 * Several source files: Removed some PORTME notes when reflection
5880 revealed that ANSI forbids that sort of breakage. Also, added
5881 lots of `unused' qualifiers here and there.
5883 * aggregate.c: (accumulate_aggregate_info) Remove local var
5884 weighting that turned out not to be used.

9047 * cmdline.c: Comment fixes.
9048 (pick_compat) Changed return type to int. Now, instead of setting
9049 glob var `compat' to the emulation, returns the emulation. All
9051 (parse_command_line) Added terminating null to end of
9052 `long_options' array definition.
9053 (pre_syntax_message) Fixes.
9054 (usage) Shows the default emulation in the syntax message by

9075 * ascii.c, postscript.c, sfm-read.c, sfm-write.c, sort.c: Include
9076 <errno.h>. GNU libc 2 enforces this!

9079 paired with wrong `if'. Comment fix.
9081 Fri May 9 16:53:52 1997 Ben Pfaff <blp@gnu.org>
9083 * getline.c: [!HAVE_LIBREADLINE] (read_console) Changed
9084 blp_getline() to getline().

9106 * output.h: (struct outp_class_struct) Removed
9107 text_get_font_position method. All references deleted.
9109 * postscript.c: Big change here. Fontmaps were completely
9110 eliminated because of a change in philosophy. Comment fixes.
9111 (struct ps_fontmap, ps2dit_map, font_family, dit2family_map)
9113 (struct ps_driver_ext) `position', `fontmap', `prop_name',
9114 `fixed_name' members removed. New members `prop_family',

9116 (static var ps_fontmaps) Removed.
9118 (ps_init_driver) Removed obsolete references, updated.
9119 Initializes `translate_x', `translate_y', `scale'. Doesn't read
9120 fontmap, of course. Refers to font names through internal_name
9121 rather than subversive means. Frees proper items.
9122 (static var option_tab[]) Removed `fontmap-file' option; renamed
9123 `fixed-font', `prop-font'.
9124 (ps_option) Corresponds to option_tab[].
9125 (read_fontmap, release_fontmap, ps_to_dit, compare_ps2dit,
9126 hash_ps2dit, compare_dit2family, hash_dit2family, compare_family,
9127 hash_family) Removed.
9128 (postopen) Generates font names from family names. Gets
9129 PostScript font name properly. New prologue file comment `!!!'
9131 (ps_open_page) Adds translate_x, translate_y to BP prologue
9132 function; gives SF argument floating-point format.
9133 (ps_text_set_font_by_name) Doesn't try to map PostScript->Groff
9134 font name. Doesn't change font family.
9135 (ps_text_set_font_by_position) Generates Groff font name from font
9136 family name instead of through table lookup.
9137 (ps_text_set_font_by_family) Renamed `ps_text_set_font_family',
9138 all references changed. Reduced to simple string assignment.
9139 (ps_get_font_name) Removed.
9140 (ps_get_font_family) Reduced to string return.
9141 (text) Doesn't save `position' since it no longer exists. Ugly
9142 kluge to save font family--fix soon?
9143 (load_font) Removed PostScript name argument.
9145 Thu May 1 14:58:59 1997 Ben Pfaff <blp@gnu.org>
9147 * postscript.c: Comment fix.

9158 * command.c: Comment fix.
9159 (static var cmd_table[]) Re-enabled EVALUATE command.
9160 (parse_cmd) Lotsa comment fixes. Fixed infinite loop in parsing
9161 of comments in script files. Now more liberal on criteria for
9162 performing a state transition--if *anything* happened correctly,
9163 not just if *everything* happened correctly.
9165 * data-out.c: (convert_F) Comment fix. Why in the fsck does
9166 Checker segfault on formatting large numbers and why in the fsck
9167 hadn't I noticed this before?
9169 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
9171 * list.q: (cmd_list) Commented out the actual output routine
9172 because of various problems. Probably will abandon the idea of
9173 using the general `crushed tables' for the LIST procedure.
9175 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
9176 clearing it. Allocates a new var_by_name dictionary before trying
9177 to add members to it.
9179 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
9180 `sib'. Changed type of `node' argument.
9181 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
9183 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
9184 [DEBUGGING] Only deletes the variable from var_by_name if that var
9187 Fri Apr 18 16:48:41 1997 Ben Pfaff <blp@gnu.org>
9189 * Makefile.am: Added include files to SOURCES. Added
9190 frequencies.q to EXTRA_DIST. Removed include/ from INCLUDES. Now
9191 includes rules for q2c. Added `boast' target.
9193 Fri Apr 18 15:42:22 1997 Ben Pfaff <blp@gnu.org>
9195 * Makefile.am: Maintainer-clean Makefile.in.
9197 * Makefile.am: Fixed redundant EXTRA_DIST line.
9199 * ascii.c: Comment fixes.
9200 (ascii_line_vert) Fixed overly aggressive range check.
9202 * display.c: Removed dead code.
9204 * list.q: Turn debugging on.
9205 (flush_table) New debug code.
9207 * sfm-read.c: (read_value_labels) malloc's the structure before
9208 trying to assign to its members.
9210 * sfm-write.c: Comment fix.
9212 * som-high.c: (som_submit_table) Sets som.t and som.d on each call
9214 (output_table) No arguments anymore--gets them through `som'
9215 global. New debug code. In crushed tables, now sets `htv' as
9216 well as `hv' to avoid bad confusion later.
9217 (dump_crush_page) New debug code.
9219 * som-low.c: (som_dump_crush_page) New debug code.
9221 Thu Mar 27 01:11:29 1997 Ben Pfaff <blp@gnu.org>
9223 All source files: Broke long lines into multiple lines.
9225 * ascii.c: (ascii_close_page) Uses host_system var in place of
9226 HOST_SYSTEM constant.
9228 * cmdline.c: (var syntax_message[]) Broke into
9229 pre_syntax_message[] and post_syntax_message[].
9230 (usage) Outputs both parts, separated by driver list.
9232 * error.h: Fixed broken formatting.
9234 * expr-opt.c: (str_search, str_rsearch) New functions.
9236 * misc.c: (blp_getdelim) Removed. All references changed to
9238 (str_search, str_rsearch) Removed.

9241 * misc.h: (blp_getline) Removed. All reference changed to
9246 * filename.c: Includes "stat.h", not <sys/stat.h>.

9252 HOST_SYSTEM constant.
9253 (write_rec_7_34) Extracts version numbers from the version string.
9256 * sort.c: Includes "stat.h", not <sys/stat.h>.
9258 * str.c: (strcasecmp) Removed.
9260 * title.c: (cmd_document) Uses host_system var instead of
9261 HOST_SYSTEM constant.
9263 * version.c: Generated on-the-fly by the Makefile instead of being
9266 * str.h: Comment fixes. Doesn't substitute for missing memmove or
9268 [!HAVE_STRNCASECMP] Declares strncasecmp().
9270 * version.h: Removed stray character. Comment fixes.
9271 (vars host_system, build_system) New vars.
9273 Mon Mar 24 21:47:31 1997 Ben Pfaff <blp@gnu.org>
9275 * Most source files: Changed formatting of copyright notice; fixed
9276 FSF address; reformatted to better conform to GNU standards;
9277 comment fixes. Added markups to prevent GNU indent from messing
9278 up my beautiful formatting :-).
9280 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
9281 that GNU indent markups can be passed through without problems.
9283 Wed Feb 19 21:30:31 1997 Ben Pfaff <blp@gnu.org>
9285 * get.c: Turned off debugging.
9287 * glob.c: (init_glob) Turned on save-file compression by default.
9289 * sfm-write.c: (sfm_write_case) Fixed bug which resulted in less
9290 compression than was possible in save files.

9300 (macro frq_extensions) Removed.
9301 (static vars min_n, max_degree) Removed, all references removed.
9302 (internal_cmd_frequencies) Doesn't handle extensions. Doesn't
9303 calculate `min_n', `max_degree'.
9304 (postcalc) Passes new arg to dump_statistics().
9305 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
9307 (dump_condensed) Adds variable name title.
9308 (sum_freqs) Removed.
9309 (calc_stats) Updated calculation algorithm.
9310 (dump_statistics) Removed warning for too-few observations.
9311 Changed table formatting. Adds variable name title if passed new

9316 * recode.c, sample.c, sort.c: Disabled debug code.
9318 * som-frnt.c: (som_set_value, som_set_float, som_set_text)
9319 Improved debug code.
9321 * var.h: (enum series frq_*) Removed Fiasco extensions.
9323 Sat Feb 15 21:26:53 1997 Ben Pfaff <blp@gnu.org>
9325 * command.c: Added PROCESS IF to command table.
9327 * Lots & lots of places, removed checks for NULLs preceding calls
9328 to free_expression(), which itself checks.
9330 * descript.q: Removed Fiasco extensions. Removed optimizations
9331 for non-weighted active files. Implemented some options.
9332 Finished polishing output format. Comment fixes. Merged
9334 (static vars n_glob_miss_list, n_glob_valid, n_glob_missing,
9335 max_degree, min_n) Removed.
9336 (macro dsc_extensions) Removed.
9337 (struct dsc_info_struct) Removed `min_n' member, all references
9339 (internal_cmd_descriptives) Removed calculation of min_n,

9342 (precalc) Eliminated redundancy. Updated for changes to
9343 descriptives_proc structure.
9344 (calc) Moved here from `descript.g'. Rewritten to calculate
9345 statistics via `moments about the mean' rather than by summing,
9346 summing squares, summing cubes, and so on.
9347 (postcalc) Rewritten for new-style statistical calculation.
9348 (display) Removed support for displaying variables across rows.
9349 No longer crushes the descriptives table. Removed ancient code.
9350 Added display of N, by variable and listwise.
9352 * descript.g: Removed; merged into `descript.q'.
9354 * expr-evl.c: (evaluate_expression) Now returns a double. For
9355 numeric results, it returns the result as well as storing it in
9356 the passed `value' structure if non-NULL. For string results it
9357 just returns 0.0 and it must be passed non-NULL. Many references
9358 to this function were optimized by use of this change, especially
9359 but not exclusively in `compute.c'.
9361 * frequencies.g: Comment fix.
9363 * glob.c: (glob var process_if_expr) New global var.
9365 * postscript.c: (static var option_tab[]) Corrected entry for

9374 (sfm_write_dictionary) Sets `n_cases' to 0.
9375 (sfm_write_case) Increments `n_cases'.
9376 (sfm_close) Attempts to seek the system file back to the header
9377 and write the number of cases in its proper slot.
9379 * som-frnt.c: (som_insert_table) Masks off expansion options since
9380 only SOPT_X_NORM seems to work sensibly.
9382 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
9383 with a `fixed' value of 2.
9385 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
9387 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10

9391 (struct descriptives_proc) Removed `miss_noweight'; new members
9392 `X_bar', `M2', `M3', `M4', `min', `max'.

9401 * glob.c: (glob var err) Removed.
9403 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
9404 doesn't have to take into account number of value labels since
9405 they're in a subtable anyway. Also, doesn't display more than 10
9406 value labels since we can't yet break pages in subtables.
9408 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
9410 * som-frnt.c: (som_change_table_size) Simple change for elegance
9411 that shouldn't change behavior.
9412 (som_set_value) Comment fix.
9414 * som-high.c: (som_submit_table) Message fix.
9416 Wed Jan 22 21:54:00 1997 Ben Pfaff <blp@gnu.org>
9418 * command.c: Added SYSFILE INFO to command table.

9433 and ')' are not written to the output in strings as literals.
9435 * sfm-read.c: (sfm_read_dictionary) New argument.
9436 (read_header) New argument. Sets the information structure's
9437 values from the header information.
9438 (read_variables) [__CHECKER__] Redefines isalnum()--some sort of
9439 bizarre Checker problem, I guess.
9440 (read_variables) Proper cleanup on lossage.
9442 * sfm.h: (struct sfm_read_info) New struct for use by
9443 sfm_read_dictionary().
9445 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
9446 currently used just for tables that can be dynamically resized and
9447 thus have to be allocated with arena_malloc() instead of
9448 arena_alloc(). All references changed.
9449 (som_change_table_size) New function.
9450 (som_insert_table) Bugfix: now inserts `cell', not `c'!
9452 * som-high.c: [GLOBAL_DEBUGGING] (check_table) Moved to som-low.c.
9453 (som_submit_table) [GLOBAL_DEBUGGING] Doesn't call check_table()
9456 * som-low.c: (draw_cell) Calls draw_table_cell() for SCON_TABLE
9458 (draw_intersection) Now takes an argument specifying the table in
9459 question. All references changed.

9465 * som.h: New enum series SOM_CREATE_* for use as create flags with
9468 * str.h: Moved a comment here from TODO.
9470 * sysfile-info.c: New file. Reference implementation.
9472 Sun Jan 19 14:22:11 1997 Ben Pfaff <blp@gnu.org>
9474 * command.c: Added RENAME VARIABLES to table of commands.
9476 * data-in.c: (dls_error) Sets `cust_field'.
9477 (parse_N) Message fix.
9478 (parse_day_count) New function.
9479 (to_roman) Never outputs VX as a `short form' of V.
9480 (parse_month) Fixed parsing of Roman numerals.
9481 (parse_trailer) Message fix.

11593 * Thanks to an unreliable IDE hard drive, I have spent the last
11594 day reconstructing my Debian GNU/Linux installation and redoing
11595 the previous day's changes--somehow I managed to save every file
11596 except for output.c and output.h. So the following changes could
11597 really be considered independent of the output.c, output.h changes
11600 * output.h, output.c: Moved the outp_configure_vec global var,
11601 outp_names struct, and enum set OUTP_S_* from output.h to output.c.

11604 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
11606 * The entire philosophy behind configuration of the output drivers
11607 changed. Now there is a termcap-type configuration where drivers
11608 to be read are determined beforehand, rather than parsing the
11609 entire output init file and storing it in memory & deciding what
11610 to actually use later. Faster & more memory-efficient at the same

11697 (text_draw) No longer considers fully justified text an internal
11700 * output.h: New flag OUTP_T_VERT; other OUTP_T_ values changed.
