3 Continue reforming procedure execution. In this phase, assert
4 that add_transformation() is not called during procedure
5 execution. Thanks to John Darrington for the suggestion.
7 * procedure.c: (static var in_procedure) New var.
8 (internal_procedure) Get rid of recursive_call local var and
10 (open_active_file) Set in_procedure and make sure it wasn't
12 (close_active_file) Reset in_procedure and make sure it was
14 (add_transformation) Make sure we're not in a procedure.
16 Wed Apr 26 19:33:52 2006 Ben Pfaff <blp@gnu.org>
18 Continue reforming procedure execution. In this phase, break
19 procedure.c into multiple files.
21 * procedure.c (vfm_last_invocation): Rename
22 time_of_last_procedure(). Update all references.
23 (struct storage_stream_info) Move to data/storage-stream.c.
24 (storage_sink_open) Ditto.
25 (destroy_storage_stream_info) Ditto.
26 (storage_sink_write) Ditto.
27 (storage_sink_destroy) Ditto.
28 (storage_sink_make_source) Ditto.
29 (var storage_sink_class) Ditto.
30 (storage_source_count) Ditto.
31 (storage_source_read) Ditto.
32 (storage_source_destroy) Ditto.
33 (storage_source_class) Ditto.
34 (storage_source_get_casefile) Ditto.
35 (storage_source_create) Ditto.
36 (null_sink_class) Move to data/case-sink.c.
37 (create_case_source) Move to data/case-source.c.
38 (free_case_source) Ditto.
39 (case_source_is_class) Ditto.
40 (create_case_sink) Move to data/case-sink.c.
41 (free_case_sink) Ditto.
43 * procedure.h: (struct case_source) Move to data/case-source.h.
44 (struct case_source_class) Ditto.

48 Thu Apr 27 09:28:25 WST 2006 John Darrington <john@darrington.wattle.id.au>
50 * automake.mk: Removed explicit dependencies for message.o, since
51 that module no longer exists.
53 Wed Apr 26 15:29:45 2006 Ben Pfaff <blp@gnu.org>
55 Start reforming procedure execution. In this phase, get rid of
56 function prototypes for never-defined functions.
58 * procedure.h: Get rid of function prototypes for never-defined
61 Wed Apr 26 12:58:46 2006 Ben Pfaff <blp@gnu.org>
63 Improve the way we handle the various parsing "states". Until now
64 we've hard-coded the state transitions in the command definition
65 file, but that's error-prone and, worse, it's redundant--we can
66 figure out what state we're in anyhow. We can cleanly handle
67 INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
69 * procedure.c (case_source_is_complex): Removed.
70 (discard_variables) No need to set pgm_state anymore.
72 Tue Apr 25 11:06:49 2006 Ben Pfaff <blp@gnu.org>
74 Finish reforming error message support. In this phase, move
75 message.c into libpspp.
77 * message.c: Move to libpspp.
79 Tue Apr 25 10:47:37 2006 Ben Pfaff <blp@gnu.org>
81 Continue reforming error message support. In this phase, drop
82 actual message printing from core code, substituting a callback,
83 and add the callback to each UI. Also, move verbose_msg() into
86 * message.c: (var err_error_count) Renamed error_count and moved
87 to ui/terminal/msg-ui.c.
88 (var err_warning_count) Renamed warning_count and moved to
90 (err_check_count) Renamed check_msg_count() and moved to
92 (dump_message) Rewrote to take stream instead of function pointer
93 and moved to ui/terminal/msg-ui.c.
94 (msg_emit) Moved its guts to ui/terminal/msg-ui.c as handle_msg()
95 and rewrote to just pass message to callback.
97 (var err_verbosity) Renamed "verbosity" and moved to
98 libpspp/verbose-msg.c.
99 (verbose_msg) Moved to libpspp/verbose-msg.c.
101 (var err_already_flagged) Removed.
102 (puts_stdout) Removed.
104 (var msg_handler) New static variable.
105 (msg_init) New function.
106 (msg_get_command_name) New function.
108 Mon Apr 24 17:40:08 2006 Ben Pfaff <blp@gnu.org>
110 Continue reforming error message support. In this phase, rename
111 all the message functions and types to start with "msg", except
112 for the ones that will be moving to other modules anyway.
114 All references to the identifiers below were updated likewise.
116 * message.c: (err_done) Renamed msg_done().
117 (err_push_file_locator) Renamed msg_push_msg_locator().
118 (err_pop_file_locator) Renamed msg_pop_msg_locator().
119 (err_location) Renamed msg_location().
120 (err_set_command_name) Renamed msg_set_command_name().
122 Mon Apr 24 14:11:33 2006 Ben Pfaff <blp@gnu.org>
124 * message.c: Use exit.h from gnulib instead of checking for and
125 defining EXIT_SUCCESS and EXIT_FAILURE by hand.
127 Sun Apr 23 22:00:23 2006 Ben Pfaff <blp@gnu.org>
129 Continue reforming error message support. In this phase, get rid
130 of message "titles" and put the message text in `struct error'.
131 Now `struct error' encapsulates a message more properly.
133 * message.c: (tmsg) Removed.
134 (msg) Use err_msg() instead of err_vmsg(). Format message
136 (err_vmsg) Renamed err_msg(). Changed interface, dropping message
137 and va_list args which are now in the error struct.
139 Sun Apr 23 20:35:28 2006 Ben Pfaff <blp@gnu.org>
141 Continue reforming error message support.
143 * message.c: Use linebreak module from gnulib instead of home-brew
145 (puts_stdout) Rewrote.
146 (dump_message) Rewrote. Changed interface and updated all callers.
147 (compulsory_break) Removed.
148 (char_is_break) Removed.
149 (break_before) Removed.
150 (break_after) Removed.
151 (macro BREAK_LONG_WORD) Removed.
153 Sun Apr 16 20:41:10 2006 Ben Pfaff <blp@gnu.org>
155 Continue reforming error message support. In this phase, we
156 divide the classification of messages along "category" and
159 * message.c: (err_vmsg) Rewrite to deal with categories and
160 severities in a straightforward manner instead of mixing them into
162 [0] (puts_stderr) Removed (dead code).
163 (msg) Changed first argument from `int' to `enum msg_class'.
166 Sun Apr 16 18:53:12 2006 Ben Pfaff <blp@gnu.org>
168 GNU standards require "file name" instead of "filename" in
169 documentation. It's nice for our code to follow the convention
172 Basically did search and replace in the whole source tree. Major
173 changes in function names or struct member names have their own
176 Sun Apr 16 15:58:56 2006 Ben Pfaff <blp@gnu.org>
178 Continue reforming error message support. In this phase, we get
179 rid of VM() and the other msg() support for "verbosity", replacing
180 it by a new function verbose_msg().
182 * message.c: (verbose_msg) New function.
183 (err_vmsg) Remove support for verbosity levels.
185 Sun Apr 16 11:46:51 2006 Ben Pfaff <blp@gnu.org>
187 Start reforming error message support. In this phase, we get rid
188 of "installation errors" and change all uses of msg() in the
189 output drivers to uses of error() or error_at_line().
191 * message.c: (err_vmsg) Get rid of IE, IS support.
193 Sat Mar 11 14:17:47 WST 2006 John Darrington <john@darrington.wattle.id.au>
195 * automake.mk: Changed the pattern specific AM_CPPFLAGS to two target
196 specific ones. Eventually there will be none at all.
198 * automake.mk: Moved the pspp binary to ui/terminal
200 Sat Mar 4 12:59:08 2006 Ben Pfaff <blp@gnu.org>
202 * In many source files, #include "compiler.h" to get GCC attribute
205 Sat Mar 4 12:28:09 2006 Ben Pfaff <blp@gnu.org>
207 * In many source files, replace INT_DIGITS by
208 INT_STRLEN_BOUND(int) and include intprops.h.
212 * Replaced '_' with '-' in most filenames.
214 * Renamed files as follows:
215 vfm.[ch] to procedure.[ch]

393 (cmd_clear_transformations) Drop requirement of interactivity.
395 * command.def: Merge the EXIT (aka Q, aka QUIT) and FINISH

446 getl_set_prompt_style().
447 (read_record) Rewrite.
448 (cmd_begin_data) Set prompt style with getl_set_prompt_style().
450 * include.c: (cmd_include) Use getl_include_syntax_file().
452 * set.q: (cmd_set) Use getl_set_prompt().
454 * html.c: (postopen) Remove "source-file" expansion variable, to
455 avoid use of getl_location().
457 * postscript.c: (postopen) Remove "source-file" expansion
458 variable, to avoid use of getl_location().
460 * cmdline.c: (parse_command_line) Drop -c command line option,
461 because it wasn't very useful. -i command line option now calls
462 getl_append_interactive(). Use new getl function interfaces.
463 Drop support for clearing dictionary between syntax files and thus
464 the "+" command line syntax.
465 (static var pre_syntax_message) Remove description of now-gone -c
466 option. Remove "+" command line syntax.
468 * main.c: (main) Only call handle_error() if the return value is

480 (global var getl_interactive) Removed.
481 (global var getl_prompt) Removed.
482 (getl_read_line) removed.
483 (readln_read) New function.
484 (read_console) Removed.
487 Sat Feb 11 22:16:21 2006 Ben Pfaff <blp@gnu.org>
489 Try to reduce some of the nastier dependencies on the error
490 module, and at the same time make PSPP nicer to deal with, by
491 getting rid of fatal errors. All the existing calls to msg (FE,
492 ...) or err_cond_fail() or err_failure() have been replaced by
493 propagating an error upward to the command-dispatch layer.
494 Unfortunately this propagation took a fair bit of extra mechanism,
495 because now a lot of functions can fail that couldn't before.
497 New command return value CMD_CASCADING_FAILURE which indicates to
498 the command processor that syntax file processing should be
499 abandoned. Many commands were modified to return
500 CMD_CASCADING_FAILURE. When this modification was trivial it
501 isn't mentioned in detail below.
503 Transformation procedures (trns_proc_func) and free functions
504 (trns_free_func) now have a `bool' return type, which is normally
505 true, but false when an I/O or other serious error occurs. All
506 transformation functions were modified to have this return type.
507 When this modification was trivial it isn't mentioned in detail
510 * pspp-error.h: (FE) Removed this error class.
512 * error.c: (err_failure) Removed.
513 (err_cond_fail) Removed.
514 (err_break) Removed (it was unused).
515 (err_check_count) Don't cause a fatal error--instead, stop reading
517 (err_vmsg) Don't have FE anymore, so no need to call terminate().
519 * any-reader.c: (any_reader_error) New function.
521 * any-writer.c: (any_writer_write) Propagate
522 scratch_writer_write_case()'s new return value.
523 (any_writer_error) New function.
524 (any_writer_close) Propagate underlying function's new return
527 * casefile.c: Add an "error state" to a casefile. A casefile that
528 encounters an I/O error enters the error state, and afterward
529 reading and writing cases fails.
530 (struct casefile) Add `ok' member.
531 (casefile_create) Set `ok' to true.
532 (casefile_destroy) Use io_error().
533 (casefile_error) New function.
534 (casefile_sleep) Now returns bool to indicate success.
535 (casefile_append) Ditto.
536 (casefile_append_xfer) Ditto.
537 (casefile_to_disk) Ditto.
538 (write_case_to_disk) Don't do anything in error state.
539 (flush_buffer) Don't do anything in error state. Use io_error().
540 (reader_open_file) Ditto.
542 (casereader_read) Don't do anything in error state. Handle
544 (casereader_read_xfer_assert) Removed, because now an I/O error
545 can occur even if the caller knows a case exists.
546 (io_error) New function.
548 * mkfile.c: (make_temp_file) Make failure non-fatal.
549 (make_unique_file_stream) Ditto.
551 * pfm-read.c: Add an error state.
552 (struct pfm_reader) Add `ok' member to indicate error state.
553 (error) Set `ok' to false.
554 (pfm_open_reader) Set `ok' to true. Make failure non-fatal.
555 (pfm_read_case) Don't do anything in error state.
556 (pfm_read_error) New function.
558 * pfm-write.c: Postpone most error checking in favor of checking
560 (pfm_open_writer) Make failure non-fatal. Check for write error
561 after writing header.
562 (buf_write) Don't do anything if error has occurred. Postpone
563 error checking. Change return type to void.
564 (write_float) Postpone error checking. Change return type to
567 (write_string) Ditto.
568 (write_header) Ditto.
569 (write_version_data) Ditto.
570 (write_format) Ditto.
572 (write_variables) Ditto.
573 (write_value_labels) Ditto.

618 means "a serious error has occurred, so abort the procedure
619 entirely". Because the hard-coded values of -1, -2, etc. were
620 becoming even a worse idea now, also introduced some macros for
621 them: TRNS_CONTINUE, TRNS_DROP_CASE, TRNS_ERROR, TRNS_NEXT_CASE,
622 TRNS_END_FILE. Also replaced all references to the hard-coded
623 values by uses of the macros.

845 Add scratch file handles.
847 Now a file handle can refer to a disk file, to an in-memory
848 structure, or to the "inline" file, instead of just to a disk
849 file. The introduction of new categories means that special cases
850 for the inline file in a few places could be eliminated, but it
851 also means that code that assumed that a handle refers to a file
852 has to check for that.

855 to access a handle after closing it (with fh_close()).

955 has been duplicated for each kind of file. Also, we had something

1417 In many files, change count parameters to parse_variables(),
1418 etc. from `int' to `size_t'. Also change related variables and
1419 struct members. Also change messages as needed (e.g. %d to %u
1420 with cast to unsigned). Also change arithmetic as necessary

1519 Sat Aug 6 21:29:15 2005 Ben Pfaff <blp@gnu.org>
1521 * factor_stats.c: Needed <config.h> included earlier.

1563 * val.h: Include "magic.h" to get definition of
1564 second_lowest_value.

1703 Sat Jul 30 22:01:32 2005 Ben Pfaff <blp@gnu.org>
1705 * Make.build: Don't append -ansi to AM_CFLAGS for GCC. Using
1706 -ansi changes the behavior of header files significantly. It
1707 causes __STRICT_ANSI__ to be defined, and some headers interpret
1708 that as cause to e.g. not use `long long' or __attribute__. The
1709 former example is bad when off_t is supposed to be `long long',
1710 and the latter prevents -Wformat from working.

2690 Sun Mar 6 17:07:20 2005 Ben Pfaff <blp@gnu.org>
2692 When the lexer sees something like `-5' in the input, it has to
2693 decide whether it's a negative numeric constant token or a '-'
2694 token followed by a positive numeric constant token. It always
2695 decides on the former, and then the parser can call
2696 lex_negative_to_dash() if it wants the latter. However, this
2697 doesn't work for the case of `-0', because negative zero is
2698 (portably) indistinguishable from positive zero. So now we divide
2699 T_NUM into two tokens, T_POS_NUM and T_NEG_NUM, to make the
2700 distinction clear. This requires a little bit of extra effort,
2701 because there were several references to T_NUM in the code base.

2704 positive and negative numeric constants.
2705 (lex_double_p) Renamed lex_is_number(). Changed return type to

2755 but fixed the real problem that was preventing the build from a

2872 * aggregate.c: (parse_aggregate_functions) Code cleanup.
2873 Important part: get rid of spurious copying of function->format to
2874 destvar->print and destvar->write.
2876 Fri Feb 11 00:08:36 2005 Ben Pfaff <blp@gnu.org>
2878 Fix bug 11916, which was confusing a variable's `index' member
2879 with the variable's position in a var_set. Although these are
2880 usually the same, they are not for array `var_set's.
2882 Took advantage of this bug as an opportunity to clean up and
2883 rewrite parse_var_set_vars().
2885 * vars-prs.c: (parse_vs_variable_idx) New function.
2886 (parse_vs_variable) Reimplement in terms of
2887 parse_vs_variable_idx().
2888 (parse_var_idx_class) New function.
2889 (add_variable) New function.
2890 (add_variables) New function.
2891 (parse_var_set_vars) Rewritten.

2893 variable into `lookup_var_idx' member that returns an int.
2894 Updated the var set implementations in obvious corresponding ways.
2895 Used compare_var_ptr_names(), hash_var_ptr_name() just added.
2897 Fri Feb 11 00:06:03 2005 Ben Pfaff <blp@gnu.org>
2899 Use our global variable compare & hash functions and give them
2900 better names. Add similar functions for dealing with double
2901 pointers to variables.
2903 * vars-atr.c: (compare_variables) Renamed compare_var_names().
2904 (hash_variable) Renamed hash_var_name().
2905 (compare_var_ptr_names) New function.
2906 (hash_var_ptr_name) New function.
2908 * t-test.q: (cmd_t_test) Use global compare_var_names(),
2910 (compare_var_name) Removed.
2911 (hash_var_name) Removed.
2913 Fri Feb 11 00:04:39 2005 Ben Pfaff <blp@gnu.org>
2917 * dictionary.c: (compare_variable_dblptrs) Rename
2918 compare_var_ptrs() and fix it to properly dereference the double

2935 problems revealed by valgrind.
2938 Wed Jan 26 11:44:11 WST 2005 John Darrington <john@darrington.wattle.id.au>
2940 * set.q: Affixed a fix to the previous fix such that we'll be OK now
2941 whether or not PAGER is set.
2943 Wed Jan 26 09:25:54 WST 2005 John Darrington <john@darrington.wattle.id.au>

2946 "invalid free" errors. Hopefully fixes bug #11722
2948 * compute.c expr-prs.c: Check that lvalues are populated before
2949 attempting to destroy them. Closes bug #11676

2987 examine.q frequencies.q
2988 html.c output.h piechart.c plot-chart.c plot-hist.c
2990 Integrated the chart rendering into the output stream
2991 (currently only works for html).
2993 Removed gratuitous use of ifndef NO_CHARTS, and replaced with
2994 dummy-chart.c for compiling without charts.
2996 * mkfile.[ch] Created.
2998 * som.[ch] tab.[ch]: Changed name of som_table to som_entity
2999 Added type element so we can tell if it's a chart or a table.
3001 * chart.h examine.q piechart.c plot-chart.c plot-hist.c: changed the
3002 API of charts to be more like that of tables.
3004 Thu Jan 13 21:00:02 WST 2005 John Darrington <john@darrington.wattle.id.au>
3006 * casefile.c main.c: Moved the SIGINT handler from casefile.c to
3007 main.c. Removed the handler for SIGQUIT.
3009 Mon Jan 10 14:43:45 WST 2005 John Darrington <john@darrington.wattle.id.au>

3020 Sat Jan 8 23:58:34 2005 Ben Pfaff <blp@gnu.org>
3022 * sort.c: (compare_initial_runs) Needed additional level of
3024 (merge_once) Fix plenty of stupid mistakes.
3026 Sat Jan 8 23:55:27 2005 Ben Pfaff <blp@gnu.org>
3028 * casefile.c: (casefile_sleep) Need to flush_buffer() after
3029 calling casefile_to_disk() or we will lose the last block in the
3030 file if the casefile started out as disk-based.
3031 (casefile_get_reader) Initialize reader->destructive to 0.
3032 (cmd_debug_casefile) Add new test pattern.
3033 (test_casefile) Define new test pattern to make sure

3036 Fri Jan 7 08:00:05 WST 2005 John Darrington <john@darrington.wattle.id.au>
3038 * Makefile.am chart.[ch] histogram.[ch] piechart.c (Modified);
3039 plot-hist.c plot-chart.c (Added) Reorganised these files in an
3040 attempt to seperate the creation and processing of charts from their
3043 * examine.q frequencies.q generated charts conditional upon the NO_CHARTS
3046 Thu Jan 6 18:48:58 WST 2005 John Darrington <john@darrington.wattle.id.au>
3048 * main.c Added a signal handler for SIGFPE
3050 * sort.c Somewhat more robust fix to the previous entry.
3052 Wed Jan 5 21:23:31 2005 Ben Pfaff <blp@gnu.org>
3054 * sort.c: (merge) Fix assertion for proper Huffman merge pattern:
3055 0 == 1 modulo 1. See Knuth 5.4.9 (vol. 3, 2nd ed.,
3056 pp. 361). Thanks to John Darrington <john@cellform.com.au> for

3068 Mon Jan 3 17:44:37 2005 Ben Pfaff <blp@gnu.org>
3070 * pfm-read.c: (read_variables) Remove direct manipulation of
3071 v->aux, which is no longer needed. Fixes bug 11483.
3073 Sat Jan 1 19:01:16 WST 2005 John Darrington <john@darrington.wattle.id.au>
3075 * data-list.c Fixed a bug in parsing delimiters.
3077 * group.c vars-atr.c Fixed buglet in hash/compare functions for alpha
3080 * percentiles.c Properly handled calculation of Tukey hinges where
3081 the number of data is small.
3083 * oneway.q Used the generic value_to_string function for independent
3084 variable instead of trying to do it ourselves.
3086 * box-whisker.c Fixed a buglet which caused a crash if the number of
3090 Fri Dec 31 16:47:45 WST 2004 John Darrington <john@darrington.wattle.id.au>

3094 * percentiles.c Fixed some bugs when calculating percentiles when
3095 there's a small number of cases.
3097 Wed Dec 29 08:18:08 WST 2004 John Darrington <john@darrington.wattle.id.au>
3099 * percentiles.[ch] Added. Calculates percentiles and Tukey hinges

3123 * cartesian.c chart.c Moved the definitions of chart_write_{xy}scale from
3124 cartesian.c and into chart.c
3126 * factorstats.[ch] Added the histogram calculations
3128 * casefile.c Removed an unused variable.
3130 * frequencies.q examine.q histogram.c Reworked the API for
3133 * piechart.c Revised the API for piecharts.
3135 * var.h Moved the definitions of freq_tab and freq out of var.h
3136 and into frequencies.q where they belong.
3138 Tue Nov 30 21:10:20 2004 Ben Pfaff <blp@gnu.org>
3140 * flip.c: (flip_file) Check for off_t separately from fseeko(),
3141 using AC_TYPE_OFF_T.
3143 Tue Nov 30 08:47:41 2004 Ben Pfaff <blp@gnu.org>
3145 * flip.c: (flip_file) If fseeko() is not available, use long int
3146 for off_t. Thanks to "Marshall DeBerry" <mdb@radix.net> for
3147 reporting the problem.
3149 Mon Nov 29 12:20:59 WST 2004 John Darrington <john@darrington.wattle.id.au>
3151 * examine.q factor_stats.[ch] Changed stderr to se_mean to avoid
3152 conflict with stdio.
3154 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
3156 * var-labs.c (var_to_string) Now returns null if the variable is null
3158 * value-labels.c (value_to_string) Made it return null if either the
3159 value or the variable is null.
3161 * hash.c (hsh_clear) Fixed a buglet.
3163 * examine.q factor_stats.[ch] Largely rewrote, because I'd started
3164 with the wrong model.
3166 * casefile.[ch] Added a function to return the casereader.case_idx
3169 * examine.q Implemented the extreme values results.
3171 John Darrington <john@darrington.wattle.id.au>
3173 * settings.h set.c glob.[ch] frequencies.q q2c.c error.c lexer.[ch]
3174 output.[ch] getline.c
3176 Plugged some memory leaks
3178 Mon Nov 15 23:47:40 2004 Ben Pfaff <blp@gnu.org>

3181 the complete suite of random number generators on expressions.
3183 * Makefile.am: Remove random.c, random.h.
3185 * random.c: Removed.
3187 * random.h: Removed.
3189 * algorithm.c: (algo_default_random) Use GSL functions.
3191 * casefile.c: (test_casefile) Use GSL RNG functions.
3193 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
3196 * sample.c: (cmd_sample) Use GSL RNG functions.
3197 (sample_trns_proc) Ditto.
3199 * set.q: (static var set_seed) Removed.

3218 * permissions.c command.def Added the PERMISSIONS command
3220 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
3222 * q2c.c: (dump_header) Don't try to emit #includes at very top of
3223 output file because that will precede #include <config.h>, which
3225 (main) Add needed headers to /* (header) */ code.
3227 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
3229 Instead of making system or portable file readers responsible for
3230 dropping and reordering variables, make them read full cases and
3231 let the caller take care of any changes.
3233 * get.c: New "case map" structure to handle this. Use for GET,
3234 IMPORT, MATCH FILES. Essentially rewrite the whole file.
3236 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
3237 changed appropriately.
3239 * sfm-read.c: (sfm_read_case) Ditto.
3241 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
3243 Decided that case_serialize() and case_unserialize() were too
3244 abstract. Also we need a couple more functions to avoid excessive
3245 copying for data in/out fast paths.
3247 * case.c: (case_serial_size) Removed.
3248 (case_serialize) Rename case_to_values() and make its argument
3249 explicitly an array of union values.
3250 (case_unserialize) Rename case_from_values() and make its argument
3251 explicitly an array of union values.
3252 (case_data_all) New function.
3253 (case_data_all_rw) New function.
3255 * casefile.c: (struct casefile) Change buffer from array of
3256 unsigned char to array of union value for better accuracy.
3257 Redefine buffer_used and buffer_size in terms of values, not
3258 bytes. Remove case_size because it is now redundant with
3259 value_cnt. Fix up all references to these members.
3261 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
3263 * barchart.c: (struct subcat) Make `label' member const to silence
3264 GCC warning with -Wwrite-strings.
3266 * cartesian.c: (struct dataset) Ditto.
3268 * case.c: Don't re-define NDEBUG if already defined.
3269 Add lots of comments.
3271 * str.c: Fix includes.
3273 * crosstabs.q: Fix includes.
3275 * examine.q: Fix includes. Fix GCC warning about unused
3278 * frequencies.q: (stat macro) Removed and replaced where used by
3281 * list.q: Fix includes.
3283 * oneway.q: Fix includes.
3285 * piechart.c: Fix includes. Only define M_PI if not already
3288 * sfm-read.c: (bswap) New function.
3289 (bswap_int32) Write in terms of bswap.
3290 (bswap_flt64) Ditto.
3292 * str.c: (ds_data) Add external definition here, needed because
3293 str.h has only an `extern inline' version.
3295 * value-labels.c: Fix includes.
3297 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
3299 Instead of providing a system or portable file writer with a raw
3300 case in the format needed for output, provide it with a regular
3301 case. The writer takes care of any needed translation.
3303 * aggregate.c: Adopt new scheme for AGGREGATE.
3304 (struct agr_proc) sfm_agr_case member removed.
3305 (write_case_to_sfm) Removed because the new interface is easier to
3308 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
3310 * pfm-write.c: Implement new scheme.
3312 * sfm-write.c: Ditto.
3314 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
3316 Instead of treating `struct file_handle' as a class to subclass
3317 into data files, system files, and portable files, instead use it
3318 as a helper that coordinates access. Now it is opaque, too.
3320 This means that most references to a struct file_handle are now
3321 changed into references to one of struct dfm_reader, struct
3322 dfm_writer, struct sfm_reader, struct sfm_writer, struct
3323 pfm_reader, or struct pfm_writer, according to what's being read
3326 Most related changes are only worth summarizing briefly.
3328 * dictionary.c: (dict_clear) Destroy aux data in deleted
3330 (dict_clear_aux) New function.
3331 (dict_create_var) Initialize aux, aux_dtor.
3332 (dict_delete_var) Destroy aux data in deleted variable.
3334 * file-handle.h: (struct fh_ext_class) Removed.
3335 (struct file_handle) Removed.
3336 (fh_init_files) Removed.
3338 * file-handle.q: Changed references to a handle's `private' member
3339 to direct references.
3340 (struct private_file_handle) Renamed file_handle.
3341 Add next, open_cnt, type, open_mode, aux members.
3342 (struct file_handle_list) Removed.
3343 (extern var inline_file) Removed.
3344 (static var file_handles) Changed from file_handle_list * to
3346 (create_file_handle) Initialize new members.
3347 (fh_close_handle) Removed.
3348 (mode_name) New function.
3349 (fh_open) New function.
3350 (fh_close) New function.
3351 (fh_parse_file_handle) Renamed fh_parse().
3353 * glob.c: (init_glob) Remove fh_init_files() call.
3355 * aggregate.c: use sfm_writer.
3356 (create_sysfile) Removed because the new interface is simpler.
3358 * apply-dict.c: Use sfm_reader.
3360 * data-list.c: Use dfm_reader.
3362 * file-type.c: Use dfm_reader.
3364 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
3366 * inpt-pgm.c: Use dfm_reader.
3368 * print.c: Use dfm_writer.
3370 * sysfile-info: Use sfm_reader.
3372 * dfm-read.c: Adopt new file handle infrastructure.
3374 * dfm-write.c: Ditto.
3376 * pfm-read.c: Ditto.
3378 * pfm-write.c: Ditto.
3380 * sfm-read.c: Ditto.
3382 * sfm-write.c: Ditto.
3384 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
3386 Break dictionary functions into separate header file.
3388 * dictionary.h: New file.
3390 * var.h: Moved dict_*() functions to dictionary.h.
3392 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
3394 Get rid of procedure-specific union in struct variable, using
3395 instead a void * pointer and a destructor function.
3397 Most related changes are only worth brief summaries.
3399 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
3400 old p.crs member in struct variable.
3402 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
3403 of old p.frq member in struct variable.
3405 * histogram.c: (draw_histogram) Takes new freq_tab arg because
3406 it's no longer possible to grab this from var->p.frq.
3408 * piechart.c: (draw_piechart) Ditto.
3410 * group.c: (group_proc_get) New function.
3412 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
3419 * main.c: (execute_command) Clear aux data in default_dict after
3420 each command. (It's debatable whether this should be done.)
3422 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
3423 member in struct variable.
3425 * means.q: Get rid of integer mode, which is not included in
3426 recent SPSS and was the only code that wanted per-variable private
3429 * var.h: (struct crosstab_proc) Removed.
3430 (struct frequencies_proc) Removed.
3431 (struct list_proc) Removed.
3432 (struct get_proc) Removed.
3433 (struct means_proc) Removed.
3434 (struct matrix_data_proc) Removed.
3435 (struct match_files_proc) Removed.
3436 (lots of enums) Removed.
3437 (struct variable) Removed members `p', `get'. Add member
3440 * vars-atr.c: (var_attach_aux) New function.
3441 (var_detach_aux) New function.
3442 (var_clear_aux) New function.
3443 (var_dtor_free) New function.
3444 (discard_variables) Use NULL instead of inline_file.
3446 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
3448 * value-labs.c Fixed the implmentation of value_to_string, so
3449 that it properly handles alpha values.
3451 * oneway.q Changed instances where labels were being probed manually,
3452 to use the canonical {var,value}_to_string functions
3454 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
3456 * examine.q cartesian.c chart.[ch] Added normal and detrended normal

3487 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
3488 to convert variables/values to strings.
3490 * examine.q Added framework for the EXAMINE command.
3492 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
3494 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
3495 subcommand types. Changed frequencies.q to use it rather then the
3496 custom parser. Dealt with the consequences. Added a test for NTILES
3497 subcommand of frequencies.

3504 incorporated the levene test into the oneway command.
3506 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
3507 global scope, since they're only relevant to T-TEST
3509 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
3511 * group.c group.h group_proc.h levene.c oneway.q t-test.q
3513 Made the t-test more consistent
3514 with the way it handles groups. That is, it now uses a hash instead
3515 of an array of 2. Also, made the levene.c file independent of the
3516 implementation of the t-test. So now levene should be fine for both
3519 * Added an oneway.q file for one way anova

3539 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
3541 Generalize casefiles to the extent that we can use them for
3542 sorting and other kinds of data transformations. Change cases to
3543 be copy-on-write to improve memory efficiency in common cases.
3544 Every access to a member of a `struct ccase' was changed to be a
3545 call to a case_*() function, especially case_data(), case_num(),
3546 case_str(), or case_data_rw(). Many instances of a local variable
3547 named "case_num" were changed to "case_idx" as a consequence.
3548 Many `struct ccase *' were changed to actual `struct ccase'
3549 because of copying semantics of cases. In several places there
3550 was a choice between updating debug code to work with the new ADTs
3551 or just deleting it because it was useless; I chose to delete it.
3553 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
3559 * aggregate.c: (struct agr_proc) Change type of `sort' to
3560 sort_criteria *. Add `break_vars', `break_var_cnt' members.

3573 * alloc.c: (out_of_memory) Make non-static.
3575 * alloc.h: Prototype out_of_memory().
3577 * casefile.c: Switched from a linked list in-memory representation
3578 to a two-level array-style representation. The linked list was
3579 appropriate when we could stick a header onto cases, but that's no
3580 longer the case. Also, the two-level array will allow for random
3581 in-memory access in case that's ever wanted. Also added the
3582 concept of a `destructive casereader', one that destroys cases in
3583 the underlying casefile as they are read out.
3584 (macro CASES_PER_BLOCK) New macro.
3585 (struct casefile) New members `value_cnt', `case_list_size',

3602 Couldn't figure out why.
3603 (casefile_to_disk) Don't call call_posix_fadvise. Rewritten to
3604 deal with new and removed members.

3941 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
3943 We're abusing the current ASCII driver by telling it to allocate a
3944 9999-line, 9999-character page in the tests. This causes some
3945 systems to curl up and die because it allocates 20 MB of
3946 contiguous RAM. This change alleviates at least part of the
3947 problem. It is mostly a stop-gap until the new output system is
3950 * ascii.c: (struct line) New structure.
3951 (struct ascii_driver_ext) Remove `page', `page_size', `line_len',
3952 `line_len_size', `n_output' members. Add `lines', `lines_cap'.

3967 * matrix.c: Dead code. Removed.
3969 * matrix.h: Dead code. Removed.
3971 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>
3973 Contrary to what I'd always understood, there is an efficient

3984 * moments.c (calc_moments): Adjust calculation of kurtosis to
3985 avoid subtracting huge numbers from huge numbers, on Michael
3988 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
3990 Rework moments routines for improved numerical stability based on
3991 Michael Kiefte's advice. Any bugs or remaining numerical problems
3992 are still mine though.
3994 There is now a struct moments1 for use with one-pass moments. It
3995 uses a provisional means algorithm as an attempt to improve
3996 accuracy of higher moments. The older struct moments now only
3997 handles two-pass moments.
3999 * aggregate.c: Use moments1 instead moments.
4001 * descript.c: Revert previous change, which is no longer needed
4002 due to the moments revision.
4004 * moments.c: (calc_moments) New function for calculating variance,
4006 (moments_pass_one) Only accumulate weights bigger than zero.
4007 (moments_calculate) Allow calculating the mean on pass one, others
4008 require pass two. Implement in terms of calc_moments().
4009 (struct moments1) New structure.
4010 (init_moments1) New function.
4011 (moments1_clear) Ditto.
4012 (moments1_create) Ditto.

4027 * descript.c (calc_descriptives): Fix assert failure when only
4028 MOMENT_MEAN is needed.
4030 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
4034 fixed problem with parsing in match_statistic() causing
4035 "DESCRIPTIVE STAT=MEAN." to barf.
4037 "MEAN" is now default if "SORT" given without specification.
4039 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
4040 generally less forgiving of syntax errors: better to have it do
4041 nothing and type it in again then to not know what it actually did
4044 z-score transformation now checks score for user-missing values
4045 and checks std_dev for SYSMIS.
4047 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
4049 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:

4307 missing values. Use set_number() or set_number_errno() instead of
4308 rnc or frnc. Removed any stuff that caused trouble in testing.

4435 Added abort() after lots of assert(0) invocations to avoid some
4436 compiler warnings. We really need a NOT_REACHED macro.

4477 Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
4479 Changed DFM from open-at-first-access to explicit-open. Before,
4480 calling dfm_get_record() or dfm_put_record() would automatically
4481 open the file. Now, you have to call dfm_open_for_reading() or
4482 dfm_open_for_writing() explicitly. This makes it possible to
4483 check permissions, file existence, etc. earlier.
4485 Also made struct file_handle more opaque, and clean up in general.

4498 (dfm_put_record) Rewrote.
4499 (dfm_push) Assert file is open and one of ours. Deal with
4500 line_number in extension record instead of file handle.
4501 (dfm_pop) Assert file is open and one of ours. Deal with
4502 line_number in extension record instead of file handle.
4503 (cmd_begin_data) Use dfm_open_for_reading(). Mark that we saw

4507 (enum constants FH_MD_*) Removed.
4508 (struct file_handle) Removed `name', `norm_fn', `fn', `where',
4509 `recform', `lrecl', `mode' members. Public references to
4510 `recform' changed to use handle_get_mode(), references to `lrecl'
4511 changed to use handle_get_record_width(). Added `private' member.
4512 (enum file_handle_mode) New.
4514 * file-handle.q: (struct private_file_handle) New structure.
4515 (struct file_handle_list) New structure.

5834 transformations, so that they know where to send their cases.

5874 pref.h. Change use of __WIN32__, __MSDOS, __DJGPP__,
5875 __CYGWIN32__, __unix__, and unix not to assume that they're
5876 defined to a nonzero value. Change use of __attribute__ to use
5877 NO_RETURN or PRINTF_FORMAT instead.
5879 * alloc.h: Move definitions for local_alloc(), local_free() here
5880 from ../pref.h.orig and simplify.
5882 * expr-evl.c: Instead of working differently based on PAGED_STACK,
5883 use a pool allocator unconditionally.

5964 Start working on a new output driver system, one that doesn't suck
5965 so much, by adding a "device-independent" output driver. The idea
5966 is to write out only a single output stream, then use separate
5967 processes to translate them into whatever formats we want. This
5968 is similar to how "groff" works with its various output drivers
5969 (grops, grotty, grodvi, ...).

6217 * command.def: Disallow MODIFY VARS in input mode, so that

6328 (dict_get_vars) New function, replaces fill_all_vars().
6329 (dict_create_var) New, replaces create_variable(). Interface
6330 drops `type' parameter, using a zero `width' to designate numeric.
6331 (dict_clone_var) New, replaces dup_variable().

6369 calling dict_destroy().

6398 reset default_handle by hand. dict_clear() will clear vectors so
6399 there's no need for that by hand.
6401 * vfm.c: (close_active_file) Move call to finish_compaction()
6402 earlier, so that we can do the compaction as a single step using
6403 dict_compact_values(). Use dict_clear_vectors().

6420 * aggregate.c: Eliminate separation of weighted and unweighted
6421 case. It made the code too obscure and I doubt it was actually
6422 faster. Instead, all code uses the "weighted" code, because
6423 that's a generalization of the "unweighted" code.
6426 (parse_aggregate_functions) No need to set FWEIGHT.
6427 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
6428 (dump_aggregate_info) Ditto.

6435 (aggregate_single_case) Don't use approx_ne().

7726 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
7728 * aggregate.c (agr_00x_end_func): Increment number of cases in
7729 sink before writing case. For streams that keep track of how many
7730 cases there are based on this value, this means that the last case
7731 will be read in on the next stream read.
7733 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
7735 Undefined behavior was invoked by referencing a freed pointer.

7760 free_aggregate_functions(), since that function already frees
7763 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
7765 A null pointer was dereferenced, causing a core dump, when
7766 PERCENTILES was specified on FREQUENCIES. This fixes the problem,

7768 Jernsletten <rjernsle@eunet.no> for reporting this problem.
7770 * arena.c: (arena_malloc) If the arena hasn't been initialized

7790 SPLIT FILE with a string variable caused a core dump. Fixed.
7792 * vfm.c: If the variable is a string then make a temporary value
7793 struct pointing to it. The underlying problem is a lot bigger
7794 than this (see TODO) but this is a stopgap for the simple case at
7797 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
7799 Nested INCLUDEs didn't work. Fixed.
7801 * getline.c: (getl_include) Set first_line to NULL in allocated
7804 Tue Mar 9 13:13:46 1999 Ben Pfaff <blp@gnu.org>

7811 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>

7819 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
7821 Comment parsing wasn't consistent with the rest of the code in its
7822 idea of where one command ends and another starts. This meant
7823 that sometimes commands would be mysteriously ignored. Thanks to
7824 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
7826 * command.c: (parse_cmd) Hand off comment parsing to new function
7827 skip_comment() in lexer.c.
7828 * lexer.c: (skip_comment) New function.
7830 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
7832 The TABLE subcommand on MATCH FILES worked only erratically at
7833 best. This fixes it. Thanks to Dr. Dirk Melcher
7834 <BZN-mdksh@t-online.de> for reporting this bug.
7836 * get.c: (mtf_compare_BY_values) When comparing string values, a
7837 difference of 1 is still a difference :-)
7838 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
7839 advance TABLE files automatically when matched. Comment fixes.
7841 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>
7843 VARIABLE LABELS rejected a slash before the first variable
7844 specification, contradicting the documentation. Thanks to Walter
7845 M. Gray <graywm@northernc.on.ca> for reporting this bug.
7847 * var-labs.c: (cmd_variable_labels) Ignore a leading slash in
7848 command specification.
7850 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>
7852 Because of an incorrect optimization in memory allocation,
7853 CROSSTABS sometimes segfaulted when asked to output multiple
7854 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
7857 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
7858 are passed to output_pivot_table() for its use.
7859 (output_pivot_table) Instead of assuming the number of columns is
7860 constant, keep track with maxcols. In general mode, use maxcells
7861 to determine whether more matrix cells need to be allocated.
7863 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
7865 CROSSTABS didn't display value labels for column and row
7866 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
7869 * crosstabs.q: (table_value_missing) If the specified value has a
7870 value label for this variable, then show it instead of the raw
7872 (display_dimensions) Delegate display of value_labels to
7873 table_value_missing.
7875 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
7877 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
7878 <BZN-mdksh@t-online.de> for reporting this bug.
7880 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
7881 if the file isn't declared as binary.
7883 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
7885 MATCH FILES corrupted memory and dumped core on some syntax
7888 * get.c: (cmd_match_files) Set file->handle to NULL before
7890 (mtf_free_file) Don't free a null dictionary.
7892 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
7894 MATCH FILES should set numeric values not available to the
7895 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
7896 <BZN-mdksh@t-online.de> for reporting this bug.
7898 * get.c: (mtf_processing) Set unused records to system-missing,
7901 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>
7903 KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
7904 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
7906 * temporary.c: (save_dictionary) Initialize var_by_name AVL tree
7907 in newly created dictionary, and add each copied variable to the
7910 Mon Jan 18 15:04:48 1999 Ben Pfaff <blp@gnu.org>
7914 * get.c: (trim_dictionary) Free variable list for KEEP after
7917 Mon Jan 18 12:57:36 1999 Ben Pfaff <blp@gnu.org>
7919 Some systems didn't like the way open_file was coded. Thanks to
7920 Hankin <hankin@rogue.consultco.com> for pointing this out.
7922 * filename.c: (open_file) Don't try to store stdin, stdout,
7923 stderr as part of an array, because that doesn't always work.
7925 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
7927 The SAVE procedure didn't save long string variables properly.
7928 Fixed by this patch. Thanks to Hankin
7929 <hankin@rogue.consultco.com> for this patch.
7931 * sfm-write.c: (write_variable) Fix off-by-one error in writing
7932 out variable pad records.
7934 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
7936 Previously, if PRINT SPACE were given a negative argument, it
7937 would report an error, then spin in an (almost) infinite loop.
7938 This fixes that behavior.
7940 * print.c: (print_space_trns_proc) After reporting a negative
7941 argument, set number of lines to print to 1.
7943 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
7945 SPSS 8.0 outputs some new record types in its system files, and it
7946 allows longer value labels. Accept these system files.
7948 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
7949 11 emitted by SPSS 8.0.
7951 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
7953 The LIST procedure was too conservative in allocating space for
7954 buffers, which caused a bug that only showed up with very long
7955 output variables. Thanks to Hankin <hankin@dunno.com> for this
7958 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
7960 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
7962 Typo meant string format specifiers weren't checked properly. I
7963 think that Hankin <hankin@dunno.com> sent me this report, but I'm
7964 willing to be corrected on this point.
7966 * format.c: (check_string_specifier) Fix obvious typo.
7968 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>

7976 * expr-opt.c: (dump_node) OP_CASENUM is acceptable.
7978 Tue Jan 5 12:47:48 1999 Ben Pfaff <blp@gnu.org>
7980 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
7981 other behavior, *sigh*. This patch hopefully fixes that. This
7982 time I've actually tested it.
7984 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
7986 * data-list.c: (read_from_data_list_free,
7987 read_from_data_list_list) Call parse_string_as_format() directly
7988 without mucking around with the field width.
7990 Tue Jan 5 12:31:19 1999 Ben Pfaff <blp@gnu.org>
7992 Occasionally, you may encounter a script that wants to be
7993 interpreted in interactive mode. Make -i emulate this behavior to
7994 allow such scripts to be executed with PSPP.
7996 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
7998 * cmdline.c: (pre_syntax_message[]) Update -i description.
8000 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
8001 when -i is given on the command line) don't treat unindented lines
8002 as starting a new command.
8004 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
8006 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
8007 mostly caused by local initialized aggregates. After egcs is
8008 fixed upstream these can be removed, but for now they're not a big
8011 * ascii.c: (ascii_postopen_driver) Checker chokes on local
8012 initialized arrays. Avoid this.
8014 * sfm-write.c: (sfm_write_dictionary) Don't use a local
8017 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
8019 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
8020 following changes avoid. Currently I compile sources with egcs
8021 1.1.1 and gcc 2.7.2.3 before sending them out.
8023 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.
8025 * ascii.c: (option_tab[]) Initialize all struct members.
8027 * avl.h: (avl_traverser_init) New macro.

8054 Thu Nov 19 12:32:45 1998 Ben Pfaff <blp@gnu.org>
8056 * data-in.c: Examined each of the parsing functions to make sure
8057 that they wouldn't dump core if they were passed a string of the
8058 wrong length, since now the DATA LIST FREE/LIST routines don't
8059 check for field width before passing it to the data parser.
8060 (parse_RBHEX, parse_AHEX) Reject odd length input.
8061 (parse_string_as_format) Reject input that's too short or too
8064 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad
8065 a field to its entire declared output width then pass it to the
8066 data-in parsing routines. This contradicted the documented
8067 behavior. This is fixed in these changes. Thanks to Mark H. Wood
8068 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
8069 free-format parsing that differed from SPSS.
8070 (cut_field) Commas and spaces are treated identically. Returns
8071 the proper column instead of a fixed 1 value.
8072 (parse_field) Removed.
8073 (read_from_data_list_free, read_from_data_list_list) Call
8074 parse_string_as_format directly instead of parse_field.

8091 FILTER_before_TEMPORARY.
8092 (procedure_write_case) Use FILTERED.

8116 (loop_2_trns_proc) Enable MXLOOPS (why was this disabled?)
8118 * main.c: (dump_token) Make kwtab[] const.
8120 * set.q: Spelling, comment fixes.
8122 * sysfile-info.c: (cmd_display) DISPLAY VECTORS not DISPLAY
8125 * vars-prs.c: (fill_all_vars) Style fix.
8127 * vfm.c: (index_to_varname) Return const.
8129 Tue Aug 4 23:49:23 1998 Ben Pfaff <blp@gnu.org>
8131 * Changes in many source files for partial -ansi -pedantic and
8132 no-debugging compliance: Remove trailing common in enum

8155 (internal_cmd_file_handle) Don't call prepend_current_directory().
8156 (fh_get_handle_by_filename) Ditto.
8158 * filename.c: Append zero byte to readlink() return value.
8160 * getline.c: (getl_read_line) I18n fix.
8162 * lexer.h: Don't use gcc features if __STRICT_ANSI__.
8164 * misc.h: Don't use gcc features if __STRICT_ANSI__.
8166 * pfm-write.c: (bufwrite) Don't try to increment a void * pointer
8169 * postscript.c: (output_encodings) Don't use local_strdup().

8205 Sun Jul 5 00:17:25 1998 Ben Pfaff <blp@gnu.org>
8207 * Several source files: Removed some PORTME notes when reflection
8208 revealed that ANSI forbids that sort of breakage. Also, added
8209 lots of `unused' qualifiers here and there.
8211 * aggregate.c: (accumulate_aggregate_info) Remove local var
8212 weighting that turned out not to be used.

11490 performing a state transition--if *anything* happened correctly,
11491 not just if *everything* happened correctly.
11493 * data-out.c: (convert_F) Comment fix. Why in the fsck does
11494 Checker segfault on formatting large numbers and why in the fsck
11495 hadn't I noticed this before?
11497 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
11499 * list.q: (cmd_list) Commented out the actual output routine
11500 because of various problems. Probably will abandon the idea of
11501 using the general `crushed tables' for the LIST procedure.
11503 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
11504 clearing it. Allocates a new var_by_name dictionary before trying
11505 to add members to it.

11508 `sib'. Changed type of `node' argument.

11659 for non-weighted active files. Implemented some options.
11660 Finished polishing output format. Comment fixes. Merged
11662 (static vars n_glob_miss_list, n_glob_valid, n_glob_missing,
11663 max_degree, min_n) Removed.
11664 (macro dsc_extensions) Removed.
11665 (struct dsc_info_struct) Removed `min_n' member, all references

11670 (precalc) Eliminated redundancy. Updated for changes to
11671 descriptives_proc structure.
11672 (calc) Moved here from `descript.g'. Rewritten to calculate
11673 statistics via `moments about the mean' rather than by summing,
11674 summing squares, summing cubes, and so on.
11675 (postcalc) Rewritten for new-style statistical calculation.
11676 (display) Removed support for displaying variables across rows.
11677 No longer crushes the descriptives table. Removed ancient code.
11678 Added display of N, by variable and listwise.
11680 * descript.g: Removed; merged into `descript.q'.
11682 * expr-evl.c: (evaluate_expression) Now returns a double. For
11683 numeric results, it returns the result as well as storing it in
11684 the passed `value' structure if non-NULL. For string results it
11685 just returns 0.0 and it must be passed non-NULL. Many references
11686 to this function were optimized by use of this change, especially
11687 but not exclusively in `compute.c'.
11689 * frequencies.g: Comment fix.

11703 (sfm_write_case) Increments `n_cases'.
11704 (sfm_close) Attempts to seek the system file back to the header
11705 and write the number of cases in its proper slot.
11707 * som-frnt.c: (som_insert_table) Masks off expansion options since
11708 only SOPT_X_NORM seems to work sensibly.
11710 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
11711 with a `fixed' value of 2.
11713 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.
11715 * sysfile-info.c: (cmd_sysfile_info) Doesn't display more than 10
11716 value labels; uses SOPT_NONE instead of SOPT_X_BOTH.
11718 * var.h: (enum series dsc_*) Removed Fiasco extensions.
11719 (struct descriptives_proc) Removed `miss_noweight'; new members
11720 `X_bar', `M2', `M3', `M4', `min', `max'.

11729 * glob.c: (glob var err) Removed.
11731 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
11732 doesn't have to take into account number of value labels since
11733 they're in a subtable anyway. Also, doesn't display more than 10
11734 value labels since we can't yet break pages in subtables.
11736 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
11738 * som-frnt.c: (som_change_table_size) Simple change for elegance

11768 (read_variables) Proper cleanup on lossage.
11770 * sfm.h: (struct sfm_read_info) New struct for use by
11771 sfm_read_dictionary().
11773 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
11774 currently used just for tables that can be dynamically resized and
11775 thus have to be allocated with arena_malloc() instead of
11776 arena_alloc(). All references changed.
11777 (som_change_table_size) New function.
11778 (som_insert_table) Bugfix: now inserts `cell', not `c'!

11826 * display.c: (cmd_display) Added DISPLAY FILE LABEL (undocumented
11827 feature of Fiasco).

11860 * temporary.c: (save_dictionary) File label is copied only if
11861 non-NULL. Doesn't try to xstrdup() dictionary documents.
11862 Adapted so as to not irritate Checker.

13811 Sun Jul 14 15:45:31 1996 Ben Pfaff <blp@gnu.org>
13813 * Many more changes to som.c especially, but these will not be
13814 documented as I have resolved to remove them. This patchlevel is
13815 being released solely so that I can fall back to it if I decide
13816 that removing the changes is not a good idea.
13818 Sat Jul 13 09:58:44 1996 Ben Pfaff <blp@gnu.org>
13820 * som.c: (global var som) New member `cum_y'.
13821 (build_target) Properly handles titles for partial tables.

13830 * command.c: (cmd_table) Added LIST, WEIGHT.
13832 * command.c: (cmd_remark) No longer frees `s' since it's not
13833 dynamically allocated.
13835 * data-out.c: (convert_f) Now correctly handles the case where
13836 abs(v->f)<1 but v->f rounds to a value of 1.00 given the specified
13837 number of decimals.
13838 (som_destroy_all_tables) Removed argument. All callers changed.
13839 (som_vline, som_hline) Argument validity checking corrected.

13866 (convert_F) Comment fix. Now won't print `-.000', etc.
13868 * descript.q: Now Z-scores work, although there appears to
13869 be a bug (which might actually be in data-out.c:convert_F()).

13871 (run_z_pass) Implemented.
13873 * var.h: Comment fixes.
13874 (dsc_z_score, descriptives_trns) New structs.
13875 (descriptives_trns) Added to any_trns as `dsc'.
13877 * error.c, error.h: New error class, IS (Installation Script
13878 error), used in those instances where the error is in the
13879 installation, but there is a script file or installation file that
13880 can be usefully referred to.

13884 * cases.c, command.c, common.c, crosstabs.q, expr-evl.c,
13885 frequencies.q, list.q, vars-prs.c, vfm.c: Removed reference to
13886 HAVE_MALLOC_H because Borland C++ alloca() is broken, so why
13887 include the corresponding header?
13889 * glob.c: (init_glob) Don't malloc term_buffer under Checker.
13890 Don't bail out if termcap can't be read.

13897 som_submission_form. Function prototypes revised.
13899 Outputting huge tables (1000s of rows) a few rows at a time
13900 is supported, though untested. May even break everything.
13901 Actually, the code doesn't even compile right now.

13919 Fri Jul 5 20:16:19 1996 Ben Pfaff <blp@gnu.org>
13921 * Thanks to an unreliable IDE hard drive, I have spent the last
13922 day reconstructing my Debian GNU/Linux installation and redoing
13923 the previous day's changes--somehow I managed to save every file
13924 except for output.c and output.h. So the following changes could
13925 really be considered independent of the output.c, output.h changes
13928 * output.h, output.c: Moved the outp_configure_vec global var,
13929 outp_names struct, and enum set OUTP_S_* from output.h to output.c.
13930 outp_configure_vec is now static.
13932 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
13934 * The entire philosophy behind configuration of the output drivers
13935 changed. Now there is a termcap-type configuration where drivers
13936 to be read are determined beforehand, rather than parsing the
13937 entire output init file and storing it in memory & deciding what
13938 to actually use later. Faster & more memory-efficient at the same
13941 * output.c: Comment fix. Removed outp_init_drivers global var.
13942 Removed all references to synonyms. New structure outp_defn. New
13943 global vars outp_macros, outp_configure_vec.

13952 (outp_clear) Renamed outp_done.
13953 (outp_list_classes) Bug fix, cleaned up.
13954 (outp_list_drivers) Not implemented anymore.
13955 (outp_configure_driver) Now a static function; simplified; now
13956 interpolates macros; supports new structure.

13962 outp_names; new enum set OUTP_S_*; new global var
13963 outp_configure_vec; function prototypes for output.c exports
13966 * main.c: (main) Calls outp_read_devices() after parsing the
13969 * cmdline.c: (parse_command_line) New option -v --verbose;
13970 --version changed to -V. --device option changed syntax to just
13971 take a single device name. Accepts key=value declaration of
13972 output init file macros. Syntax message updated.
13974 * filename.c: (expand_line) New function.
13975 (interp_environ_vars) Renamed interp_vars; no longer uses
13977 (blp_getenv) Allows $ARCH and $VER pseudo-environment-vars to be
13978 overridden by real environment vars.
13979 (search_path) Uses verbose_msg() instead of #ifdef'd printf().
13980 * filename.h: interp_environ_vars() renamed interp_vars().
13982 * error.c, error.h: Added extern variable `verbosity', message
13985 * error.c: (vmsg) Support message class MM.
13986 (verbose_msg) New function.
13988 * descript.q: (generate_z_varname) Bug fix in generation of
13990 (dump_z_table) Bug fix in column headers.
13992 * ascii.c: (ascii_init_driver) Changed minimum number of lines per
13993 page from 29 to 15. Don't set a default for ops[OPS_INIT,
13994 OPS_DONE]. Writes the uninit string when the driver is closed.
13995 (ascii_open_page) Write the init string before the first page.
13996 (output_shorts) Form of main loop changed from `while' to `for'.
13997 Bug fix with overstrikes: the character is printed *after* the
13998 backspace. Eliminated a lot of `& 0xff' modifiers.
13999 (advance_to_left_margin) New function.
14000 (return_carriage, output_lines) Handle left margin.
14002 Thu Jul 4 00:35:59 1996 Ben Pfaff <blp@gnu.org>

14014 (output_lines) Now handles overstriking and font changes properly;
14015 some code moved to output_shorts.

14023 Now you can set a vertical height on writing text.
14024 * ascii.c: (delineate) Keeps track of vertical position.
14025 (text_draw) No longer considers fully justified text an internal
14028 * output.h: New flag OUTP_T_VERT; other OUTP_T_ values changed.
14030 Tables' titles are drawn; they can have variable height.
14031 * som.c: `som' struct has new member, title_height.
14032 (draw_title) New argument. Moved within file. All caller

14060 (dump_page) New arguments.
14061 (som_submit_table) Handle new variables.
14063 * som.c, som.h: (som_submit_table) New arguments. All callers
