654 Improvements to system file reader and writer.
656 First, move all detailed knowledge of very long strings into
657 sys-file-private.[ch], so that this nasty stuff can be isolated.
659 * sys-file-private.c (REAL_VLS_CHUNK): New macro.
660 (EFFECTIVE_VLS_CHUNK): New macro.
661 (min_int): New function.
662 (max_int): New function.

672 * sys-file-private.h (MIN_VERY_LONG_STRING): Removed.
673 (EFFECTIVE_LONG_STRING_LENGTH): Removed.
674 (struct sfm_var): New structure.
676 Next, improvements to the system file reader.
678 * sys-file-reader.h (struct sfm_read_info): Changed `case_cnt' to
679 type casenumber. Added `version_major', `version_minor',
682 * sys-file-reader.c (struct sfm_reader): Replaced `flt64_cnt' by
683 `oct_cnt'. Rename `vars', `var_cnt' to `sfm_vars', `sfm_var_cnt'.
684 Change `case_cnt' to type casenumber. Removed `has_vls'.
685 (struct sfm_var): Removed.
686 (sfm_open_reader): Don't warn on wrong case size if the file was
687 written by SPSS 13, which tends to get it wrong. Use
688 sfm_dictionary_to_sfm_vars.
689 (read_header): Always output system file info.
690 (read_variable_record): Simplify code for reading missing values.
691 (read_machine_int32_info): Save version numbers from system file
692 into info struct passed as new argument.
693 (read_long_string_map): Restructured to use new sys-file-private
695 (read_value_labels): Use size_overflow_p.
696 (sys_file_casereader_read): Get rid of distinction between fast
697 and slow paths. Use information provided by sys-file-primate's
698 struct sfm_var to simplify code.
699 (skip_whole_strings): New function.
700 (read_int32): Renamed read_int. Changed return value to int.

703 double. Updated all callers.
704 (int32_to_native): Removed. Changed callers to use
706 (flt64_to_double): Removed. Changed callers to use float_convert.
708 Finally, get rid of int32, flt64 terminology and types in system
709 file writer. The former wasn't very useful since a POSIX "int"
710 can hold the whole range of int32 and we generally didn't have a
711 need for it to be exactly-32-bits, just at-least-32-bits. The
712 latter was inconvenient because we had to assume that it could be
713 different from double and thereby convert special values SYSMIS,
714 HIGHEST, LOWEST to and from it in multiple places. Instead, now
715 we just use "int" and "double" in most places, and do conversions,
716 if necessary, very close to where we do I/O. This change meant
717 that the writer code couldn't represent records in the file as C
718 structs any longer, but that's no great loss. The code actually
719 seems to be more readable without them.
721 Simplify the compression buffering code: only buffer as much as
722 necessary, which is no more than eight 8-byte units at any given

731 type casenumber. Renamed `vars' to `sfm_vars', `var_cnt' to
732 `sfm_var_cnt'. Replaced `buf', `end', `ptr', `x', `y' for
733 compression buffering by `opcodes', `opcode_cnt', `data',
734 `data_cnt'. Renamed `var_cnt_vls' as `segment_cnt'.

947 Until now, the procedure code has provided a case to the
948 case_source, which has filled in the data values that come from
949 the active file. "Left" data values that don't come from the
950 active file naturally stay the same from case to case, because the
951 procedure code keeps using that same case.
953 One of the compromises that comes with the new procedure code is
954 that the active file allocates and provides its own case, which
955 the procedure code then has to resize to provide room for any
956 other variables that should go in the case and then fill in the
957 values of "left" variables. Then, when we're done with that case,
958 we have to save the values of "left" variables to copy into the
959 next case read from the active file.

1195 (fn_normalize): Removed. Caller changed to use the canonicalize
1197 (fn_get_cwd): Removed. Only user was fn_normalize.
1198 (fn_is_absolute): Really only test for absolute names.
1199 (fn_is_special): Use pipe files if HAVE_POPEN, not if we're in
1201 (fn_readlink): Removed, as it was only used fn_normalize.
1202 (fn_exists): Assume the stat function is available; gnulib does.
1203 (fn_open): Use pipe files if HAVE_POPEN, not if we're in unix.
1205 Sat Feb 3 21:52:17 2007 Ben Pfaff <blp@gnu.org>
1207 * dictionary.c (dict_create_vector_assert): New function.
1209 Wed Feb 7 21:25:15 2007 Ben Pfaff <blp@gnu.org>
1211 * file-name.c (fn_normalize): Correct name of function
1212 fn_is_special. Thanks to John McCabe-Dansted <gmatht@gmail.com>
1213 for pointing this out.
1215 Thu Feb 1 16:53:37 2007 Ben Pfaff <blp@gnu.org>
1217 We are using a single member in struct file_handle, the "name"
1218 field, for more than one purpose. When it begins with '"', it's a
1219 file name; otherwise, it's a token that can be used to identify
1220 it. When that assertion fires, it's because we searched for the
1221 name case-sensitively as a file name (so that there was no match),
1222 and then we try to insert it case-insensitively as a token, which
1223 fails because duplicates aren't allowed.
1225 Solution: break the two purposes into two separate fields. This
1226 fixes the problem and likely makes the code easier to read too.
1228 Fixes bug #18922. Thanks to John Darrington for bug report and
1231 * file-handle-def.c (struct file_handle): New `id' member.
1232 (fh_from_name): Rename fh_from_id. Update all callers.
1233 (create_handle): New `id' parameter. Update all callers.
1234 (fh_create_file): Ditto.
1235 (fh_get_id): New function.
1237 Mon Jan 15 16:18:10 2007 Ben Pfaff <blp@gnu.org>
1239 * case.c (case_is_null): Change return type to bool.
1241 Mon Jan 15 10:57:28 2007 Ben Pfaff <blp@gnu.org>
1245 * case.c (case_clone) [DEBUGGING]: When debugging, don't use
1246 reference counting to share data. This makes it easy for
1247 valgrind, etc. to find accesses to cases that have been destroyed
1248 but have been kept around by another user's ref-count. This often
1249 happens when the data set is small enough to find in memory; if a
1250 bigger data set that would overflow to disk were used, then data
1251 corruption would occur.
1253 Mon Jan 15 10:55:18 2007 Ben Pfaff <blp@gnu.org>
1257 * case.c (case_unshare): Make it check internally whether the
1258 ref_cnt is greater than 1, so that the callers don't have to.
1259 Update callers not to check.
1261 Mon Jan 15 10:53:01 2007 Ben Pfaff <blp@gnu.org>
1263 Before, I was thinking that I might want to get rid of reference
1264 counting at some point. Now, I'm pretty sure that it's here to
1265 stay. Thus, because we have to store the value_cnt anyway for
1266 reference-counted cases, we might as well expose it to users.
1268 * case.c (case_get_value_cnt): New function.
1269 (case_resize): Drop OLD_CNT argument. Update all callers. Only
1270 resize case if its size actually changed.
1272 * casefile.c (casefile_append_xfer): Use case_get_value_cnt
1273 instead of peeking inside struct case directly.
1274 (casefile_append): Ditto.
1276 Mon Jan 15 10:50:22 2007 Ben Pfaff <blp@gnu.org>
1278 Get rid of the inlines for the case functions, which made the
1279 header file hard to read. (Also, in testing with "-O2 -DNDEBUG",
1280 the inlines didn't speed up "make check" at all, which is not a
1281 perfect benchmark but seems indicative.)
1283 * case.c: Remove #ifdef DEBUGGING...#endif around many function
1284 definitions. Remove some assertions on nonnull pointers that were
1285 redundant with a pointer dereference soon after in the function.
1287 (struct case_data): Move definition here from case.h.
1291 (case_data_wr): Ditto.
1293 Sun Jan 14 21:41:12 2007 Ben Pfaff <blp@gnu.org>
1295 * automake.mk: Add casedeque.h to sources.
1297 * casedeque.h: New file.
1299 * procedure.c: (struct dataset) Change lag_count, lag_head,
1300 lag_queue member into single struct casedeque member. Update all
1301 users to use the casedeque instead.
1304 Sun Jan 14 21:43:12 2007 Ben Pfaff <blp@gnu.org>
1306 * procedure.c: Simplify lagged cases interface. Updated all
1307 clients--well, the only client--to use the simplified interface.
1308 (dataset_n_lag) Removed.
1309 (dataset_set_n_lag) Removed.
1310 (dataset_need_lag) New function.
1312 Tue Jan 9 07:20:05 WST 2007 John Darrington <john@darrington.wattle.id.au>
1314 * dictionary.c procedure.c: More changes to ensure that callbacks occur
1315 whenever appropriate, but only when the dataset/dictionary is in a
1318 Sun Jan 7 08:33:04 WST 2007 John Darrington <john@darrington.wattle.id.au>
1320 * dictionary.c dictionary.h : Added callbacks for change of filter and
1321 split variables. Refactored some code to ensure that callbacks get
1322 invoked when appropriate.
1324 * procedure.c (proc_cancel_temporary_transformations): Make sure that
1325 replace_dict callback occurs when permanent_dict replaces the current
1328 Wed Jan 3 11:02:11 WST 2007 John Darrington <john@darrington.wattle.id.au>
1330 * dictionary.c dictionary.h : Added callback for when the weight
1331 variable of a dictionary changes.
1333 Mon Jan 1 10:36:26 WST 2007 John Darrington <john@darrington.wattle.id.au>
1335 * dictionary.c dictionary.h : Added replace_source and replace_dict
1336 callbacks, and functions to deal with them.
1338 Fri Dec 22 13:56:08 2006 Ben Pfaff <blp@gnu.org>
1340 Simplify missing value handling.
1342 * missing-values.h (enum mv_class): New type.
1343 (enum mv_type): Moved definition into missing-values.c and renamed
1344 each MV_* to MVT_*, to distinguish them from the exposed mv_class
1345 enums. Updated all uses.
1346 (struct missing_values): Changed type of `type' from `enum
1347 mv_type' to `int' because the definition is no longer exposed.
1349 * missing-values.c (mv_is_value_missing): Add new enum mv_class
1350 parameter. Update all callers.
1351 (mv_is_num_missing): Ditto.
1352 (mv_is_str_missing): Ditto.
1353 (mv_is_value_user_missing): Removed. Changed callers to use
1354 mv_is_value_missing.
1355 (mv_is_num_user_missing): Removed. Changed callers to use
1357 (mv_is_str_user_missing): Removed. Changed callers to use
1359 (mv_is_value_system_missing): Removed. Changed callers to use
1360 mv_is_value_missing.
1361 (mv_set_type): Removed. Changed callers to use mv_clear.
1362 (mv_clear): New function.
1364 * variable.c (var_is_value_missing): Add new enum mv_class
1365 parameter. Update all callers.
1366 (var_is_num_missing): Ditto.
1367 (var_is_str_missing): Ditto.
1368 (var_is_value_user_missing): Removed. Changed callers to use
1369 var_is_value_missing.
1370 (var_is_num_user_missing): Removed. Changed callers to use
1372 (var_is_str_user_missing): Removed. Changed callers to use
1374 (var_is_value_system_missing): Removed. Changed callers to use
1375 var_is_value_missing.
1377 * casefilter.c (struct casefilter): Use enum mv_class in place of
1379 (casefilter_variable_missing): Adapt to new member.
1380 (casefilter_create): Change signature to take enum mv_class,
1383 Fri Dec 22 20:08:38 WST 2006 John Darrington <john@darrington.wattle.id.au>
1385 * casefile-factory.h fastfile-factory.c fastfile-factory.h: New files.
1387 * case-sink.c case-sink.h procedure.c procedure.h
1388 storage-stream.c: Now uses the factory.
1390 Sat Dec 16 22:05:18 2006 Ben Pfaff <blp@gnu.org>
1392 Make it possible to pull cases from the active file with a
1393 function call, instead of requiring indirection through a callback
1396 * case-source.h (struct case_source_class): Change ->read function
1397 to return a single case, instead of calling a callback function
1398 for each case. Change ->destroy function to return an error
1401 * case-source.c (free_case_source): Pass along the value returned
1402 by the case_source ->destroy function.
1404 * procedure.c (struct write_case_data): Removed.
1405 (struct dataset): Added some members to track procedure state.
1406 (procedure): Optimize the trivial case at this level.
1407 (internal_procedure): Re-implement in terms of proc_open,
1408 proc_read, proc_close.
1409 (proc_open) New function.
1410 (proc_read) New function.
1411 (proc_close) New function.
1412 (write_case) Moved into proc_read.
1413 (close_active_file) Moved closing of data source into proc_close.
1415 * storage-source.c: Rewrote to conform with modified
1416 case_source_class interface.
1418 * transformations.c (trns_chain_execute): Added argument to allow
1419 starting execution from an arbitrary transformation. Updated
1422 * transformations.h (enum TRNS_NEXT_CASE) Renamed TRNS_END_CASE.
1424 Sat Dec 16 14:09:25 2006 Ben Pfaff <blp@gnu.org>
1426 * sys-file-reader.c (read_display_parameters): Don't assume that
1427 MEASURE_* and ALIGN_* have the same values found in system files.
1429 * sys-file-writer.c (write_variable_display_parameters): Ditto.
1431 * variable.h: Change MEASURE_NOMINAL, MEASURE_ORDINAL,
1432 MEASURE_SCALE to be 0-based instead of 1-based. This also fixes
1433 the value of n_MEASURES, which was off by 1 (at least from my
1436 Sat Dec 16 12:17:34 WST 2006 John Darrington <john@darrington.wattle.id.au>
1438 * dictionary.c dictionary.h vardict.h variable.c: Added optional
1439 callbacks which are invoked when the dictionary or its
1440 variables are changed.
1442 * missing-values.c missing-values.h value-labels.c: Tidied up
1443 consistency checks, and made some of them return false
1444 instead of assert-failing.
1446 Wed Dec 13 19:30:11 2006 Ben Pfaff <blp@gnu.org>
1448 * calendar.c (calendar_days_in_month): New function.
1450 Mon Dec 11 07:53:39 2006 Ben Pfaff <blp@gnu.org>
1452 * value-labels.c (hash_int_val_lab): Only hash as many bytes as
1453 the value label's width.
1455 Sun Dec 10 14:21:29 2006 Ben Pfaff <blp@gnu.org>
1457 * sfm-private.h: Move contents into sys-file-writer.c, which is
1458 the only remaining user. Removed Borland C++-specific directives.
1460 * sys-file-reader.c: Clean up and rewrite entire file. The
1461 rewritten version is simpler and better abstracted, and should be
1462 easier to maintain and extend. It avoids using structures to read
1463 file data, which is prone to padding variations among compilers.
1464 It should also handle non-IEEE 754 system files, although I
1465 haven't been able to find any. It has been tested against many
1466 .sav files obtained from the Web and found to produce the same
1467 results as the earlier version of the code, or in some cases
1468 improved results. It is more tolerant of format variations found
1471 * sys-file-reader.h (struct sfm_read_info): Removed `big_endian'
1472 member, putting an enum integer_format in its place. New member
1473 `float_format'. Changed `compressed' member to type bool.
1475 Sun Dec 10 13:48:53 2006 Ben Pfaff <blp@gnu.org>
1477 * dictionary.c (dict_delete_consecutive_vars): New function.
1479 Sat Dec 9 20:08:25 2006 Ben Pfaff <blp@gnu.org>
1481 * file-name.c (fn_search_path): Remove prefix arg that was unused
1482 by any caller. Updated all callers.
1484 Sat Dec 9 20:04:22 2006 Ben Pfaff <blp@gnu.org>
1486 * format.c (fmt_dollar_template): Use user's decimal point
1487 character. Add assertion.
1489 Sat Dec 9 20:02:25 2006 Ben Pfaff <blp@gnu.org>
1491 * format.c (fmt_dollar_template): New function, based on
1492 dollar_format_template from var-type-dialog.c.
1494 Sat Dec 9 18:05:59 2006 Ben Pfaff <blp@gnu.org>
1496 * data-out.c (output_scientific): Fix bad assumption that "buf" is
1499 Sat Dec 9 17:23:23 2006 Ben Pfaff <blp@gnu.org>
1501 Finish converting struct variable to an opaque type. In this
1502 phase, we add remaining setter and getter functions, convert the
1503 remaining PSPP code to use them, and do a bunch of cleanup. The
1504 resulting changes are pervasive but mostly trivial, and only the
1505 notable changes are logged.

1513 (case_data_rw): Renamed case_data_rw_idx.
1515 * case.h (case_data): New function with old name and an interface
1516 that takes a variable instead of an index, which is easier to
1517 use. Updated all callers to use the new interface, or to use the
1518 new *_idx function (see above).
1521 (case_data_rw): Ditto.
1523 * category.c (cat_stored_values_destroy): Changed interface to
1524 take a struct cat_vals * instead of a struct variable *.
1526 * dictionary.c (dict_clone): Use new vector_clone function.
1527 (dict_clear) Use new var_destroy function.
1528 (add_var) New function.
1529 (dict_create_var) Rewrite in terms of dict_create_var_assert.
1530 (dict_create_var_assert) Rewrite in terms of add_var.
1531 (dict_clone_var) Rewrite in terms of dict_clone_var_assert.

1533 (dict_lookup_var) Use new var_create, var_destroy functions.
1534 (dict_contains_var) Rewrite in terms of new vardict functionality.
1535 (set_var_dict_index) New function.
1536 (set_var_case_index) New function.
1537 (reindex_vars) New function.
1538 (dict_delete_var) Rewrite in terms of new vardict functionality.
1539 (dict_reorder_var) Ditto.
1540 (dict_reorder_vars) Ditto.
1541 (rename_var) New function.
1542 (dict_rename_var) Use rename_var.
1543 (dict_rename_vars) Use pool to simplify code. Use rename_var.
1544 (dict_get_compacted_idx_to_fv) Rename
1545 dict_get_compacted_dict_index_to_case_index, update callers.
1546 (dict_create_vector) Use new vector_create function.
1547 (dict_clear_vectors) Use new vector_destroy function.
1548 (set_var_short_name_suffix) Move here from variable.c, renamed
1549 from var_set_short_name_suffix, make static, update caller.
1551 * sys-file-private.c: New file.
1552 (sfm_width_to_bytes) Moved here from variable.c, renamed from
1553 width_to_bytes, update callers.
1555 * sys-file-private.h: New file. Later it will supplant
1556 sfm-private.h; for now it supplements it.
1557 (macro MIN_VERY_LONG_STRING) New macro.
1558 (macro EFFECTIVE_LONG_STRING_LENGTH) New macro, from value.h.
1560 * sys-file-reader.c: Use MIN_VERY_LONG_STRING - 1 where
1561 MAX_LONG_STRING was used before.
1563 * sys-file-writer.c: Ditto.
1565 * value-labels.c: Change the paradigm here to be that a null
1566 pointer is OK for a struct val_labs * in most cases; it just
1567 represents an empty set of value labels.
1568 (val_labs_copy) A copy of a null set is a null set.
1569 (val_labs_count) A null set has 0 labels.
1570 (val_labs_replace) Change return type to void. Rewrite for
1572 (val_labs_find) A null set does not contain the value.
1573 (value_to_string) Moved to variable.c, renamed var_get_value_name,
1574 transposed argument order, updated all callers.
1576 * value.c: New file.
1577 (value_dup) Moved here from variable.c.
1578 (compare_values) Ditto.
1581 * value.h: (macro MAX_SHORT_STRING) Rewrote for simplicity.
1582 (macro MAX_LONG_STRING) Removed, because it was only interesting
1583 for system files, not for general code.
1584 (macro MAX_VERY_LONG_STRING) Ditto.
1585 (macro EFFECTIVE_LONG_STRING_LENGTH) Moved to sys-file-private.h.
1586 (macro MAX_ELEMS_PER_VALUE) Removed, as it was unused.
1588 * vardict.h: New file, for an interface between variables and
1591 * variable.c: A lot of functions were moved around, for better
1593 (struct variable) Move definition here, from variable.h.
1594 (var_type_adj) Removed--makes i18n hard.
1595 (var_type_noun) Ditto.
1596 (var_create) New function.
1597 (var_clone) New function.
1598 (var_destroy) New function.
1599 (var_set_name) Assert that variable is not in a dictionary.
1600 (compare_var_names) Rename compare_vars_by_name and fix a couple
1601 of callers who thought the args were strings.
1602 (hash_var_name) Rename hash_var_by_name.
1603 (compare_var_ptr_names) Rename compare_var_ptrs_by_name.
1604 (hash_var_ptr_name) Rename hash_var_ptr_by_name.
1605 (var_is_very_long_string) Removed, because it was only interesting
1606 to system file code.
1607 (var_set_missing_values) Allow the argument to be the wrong width,
1608 as long as we can resize it. Simplify callers who were doing the
1609 resizing themselves.
1610 (var_get_value_labels) New function.
1611 (var_has_value_labels) New function.
1612 (var_set_value_labels) New function.
1613 (alloc_value_labels) New function.

1615 (var_replace_value_label) New function.
1616 (var_clear_value_labels) New function.
1617 (var_lookup_value_label) New function.
1618 (var_get_value_name) Moved here from variable.c, renamed from
1619 var_get_value_name, transposed argument order, updated all
1621 (var_to_string) Moved here, from variable-label.c.
1622 (var_set_leave) New function.
1623 (var_get_leave) New function.

1664 * value-labels.c (destroy_atoms): New function.
1665 * value-labels.c (atom_create): Call destroy_atoms in atexit handler.
1667 Thu Dec 7 17:38:26 2006 Ben Pfaff <blp@gnu.org>
1669 Thanks to Jason Stover for pointing out this problem.
1671 * data-out.c (output_number): Use gsl_finite from GSL, which is
1672 portable, instead of isfinite, which is not.
1675 Thu Dec 7 15:22:38 WST 2006 John Darrington <john@darrington.wattle.id.au>
1677 * variable.c variable.h (value_dup): New function.
1679 Mon Dec 4 22:20:17 2006 Ben Pfaff <blp@gnu.org>
1681 Start converting struct variable to an opaque type. In this
1682 phase, we add a bunch of setter and getter functions and convert
1683 most of the PSPP code to use them. The resulting changes are
1684 pervasive but mostly trivial, and only the notable changes are
1687 * format.c (fmt_equal): New function.
1689 * variable.c (var_type_is_valid): New function.

1962 Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
1963 ALL) and additional underlying system file issues.
1965 Thanks to John Darrington for review.
1967 First problem: var_hash points to variables not owned by the
1968 sys-file-reader, which the caller may free or modify. Use an
1969 array of sfm_vars instead, as done earlier (e.g. CVS version
1972 * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
1973 members and remove all code that references it. Add vars, var_cnt
1974 members. Remove fix_specials member, which was unused.
1975 (struct sfm_var) Remove name member, which was unused.
1976 (sfm_close_reader) Free vars member instead of var_hash.
1977 (compare_var_shortnames) Removed.

1980 (compare_var_index) Removed.
1981 (sfm_read_case) Use vars instead of var_hash.
1983 Second problem: we're confused about when we actually have very
1984 long strings, causing us to choose incorrectly between slow path
1985 and fast path in sfm_read_case.
1987 * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
1988 have very long strings, not when we have long variable names,
1989 which is an unrelated feature.
1991 Tue Jun 27 12:06:49 2006 Ben Pfaff <blp@gnu.org>
1993 * variable.h: Move var_set and variable parsing declarations to
1994 new header, src/language/lexer/variable-parser.h. Modified lots
1995 of files to include the new header.
1997 Sun Jun 25 22:39:32 2006 Ben Pfaff <blp@gnu.org>
1999 * value-labels.c (value_to_string): When there's no value label,
2000 format the variable according to its print format, instead of
2001 always effectively using A or F format.

2146 add_process_if_trns().
2147 (discard_variables) Get rid of redundant call to

2174 shouldn't be doing any output. Move it into the individual
2175 procedures instead. This also adds some flexibility.
2177 Updated many users of procedure_with_splits() and
2178 multipass_procedure_with_splits() to call
2179 output_split_file_values() and to deal with increased use of

2199 Fri May 5 22:48:50 2006 Ben Pfaff <blp@gnu.org>
2201 Continue reforming procedure execution. Change
2202 internal_procedure() so that it calls open_active_file() and

2268 * storage-stream.c: Add missing function comments.
2270 Tue May 2 15:50:21 2006 Ben Pfaff <blp@gnu.org>
2272 Continue reforming procedure execution. In this phase, add some
2273 new, needed functionality to storage-stream.
2275 * storage-stream.c: (storage_source_decapsulate) New function.
2277 Tue May 2 15:43:36 2006 Ben Pfaff <blp@gnu.org>
2279 * variable.c (width_to_bytes): Declarations must precede
2280 statements for C90 compliance.
2282 Tue May 2 10:42:05 WST 2006 John Darrington <john@darrington.wattle.id.au>
2284 * data-out.c, data-in.c, variable.c, variable.h: New functions
2285 copy_mangle and copy_demangle for reading/writing cases; emulates the
2286 way SPSS deals with strings > 255 bytes.
2288 * sys-file-reader.c sys-file-writer.c: Added support for Record 7,
2289 subtype 14 needed for strings longer than 255 bytes.
2291 * dictionary.c, format.def, value.c : Updated to use MAX_STRING
2292 instead of literal values. Also fixed some constness issues.
2294 * format.h: Constness
2296 * sfm-private.h: Renamed the case_size identifier, since I discovered
2297 that SPSS's respect for this variable is very nominal.
2299 Mon May 1 15:45:42 2006 Ben Pfaff <blp@gnu.org>
2301 Change case limit type from int to size_t.
2303 * dictionary.c: (struct dictionary) Change type of case_limit
2305 (dict_get_case_limit) Change return type.

2311 and invert sense. Fix up all references.
2313 Wed Apr 26 19:39:28 2006 Ben Pfaff <blp@gnu.org>

2332 Wed Apr 26 14:55:19 2006 Ben Pfaff <blp@gnu.org>
2334 * variable.h: (struct variable) Remove `init' member and all
2335 references to it from other files. It was initialized in several
2336 places, but nothing really ever used it for anything worthwhile.
2337 Thanks to Jason Stover for pointing out how confusing this
2340 Sun Apr 23 22:04:45 2006 Ben Pfaff <blp@gnu.org>
2342 Continue reforming error message support. In this phase, get rid
2343 of message "titles" and put the message text in `struct error'.
2344 Now `struct error' encapsulates a message more properly.
2346 * casefile.c: (io_error) Use err_msg() instead of err_vmsg().

2355 Sun Apr 16 18:49:51 2006 Ben Pfaff <blp@gnu.org>
2357 GNU standards require "file name" instead of "filename" in
2358 documentation. It's nice for our code to follow the convention
2361 * casefile.c: (struct casefile) Rename `filename' member to
2362 `file_name'. Updated all references.
2364 * file-name.c: [!unix] (struct file_identity) Rename
2365 normalized_filename member to normalized_file_name. Updated all
2368 Sun Apr 16 18:35:33 2006 Ben Pfaff <blp@gnu.org>
2370 We don't really support anything but Unix-like environments well,
2371 so we might as well de-obfuscate by writing directory and path
2372 separators explicitly.
2374 * file-name.h: (macro DIR_SEPARATOR) Removed. Changed all usages
2376 (macro PATH_SEPARATOR) Removed. Changed all usages to just ':'.
2377 (macro DIR_SEPARATOR_STRING) Removed. Changed all usages to just
2379 (macro PATH_SEPARATOR_STRING) Removed. Changed all usages to just
2382 Sun Apr 16 18:28:35 2006 Ben Pfaff <blp@gnu.org>

2395 Sun Apr 16 16:42:47 2006 Ben Pfaff <blp@gnu.org>
2397 * filename.c: (fn_dirname) Renamed fn_dir_name(), all references
2399 (fn_basename) Removed (dead code).
2400 (fn_absolute_p) Renamed fn_is_absolute(), all references updated.
2401 (fn_special_p) Renamed fn_is_special(), all references updated.
2402 (fn_exists_p) Renamed fn_exists(), all references updated.
2404 Sun Apr 16 16:33:58 2006 Ben Pfaff <blp@gnu.org>
2406 * filename.c: (fn_tilde_expand) Rewrite for cleaner code.
2407 Also, now it only tilde-expands file names, not paths.
2408 (fn_search_path) Tilde-expand one directory at a time.
2410 Sun Apr 16 16:28:06 2006 Ben Pfaff <blp@gnu.org>
2412 * filename.c: (fn_search_path) rewrite for cleaner code. Also,
2413 get rid of non-Unixlike version of the code, which has probably
2415 (fn_prepend_dir) Removed (dead code).
2417 * filename.h: (macro DIR_SEPARATOR_STRING) New.
2418 (macro PATH_SEPARATOR_STRING) New.
2419 Sun Apr 16 16:05:28 2006 Ben Pfaff <blp@gnu.org>
2421 Continue reforming error message support. In this phase, we get
2422 rid of VM() and the other msg() support for "verbosity", replacing
2423 it by a new function verbose_msg().
2425 * filename.c: (fn_search_path) Use verbose_msg() instead of
2428 Sat Apr 15 19:53:19 2006 Ben Pfaff <blp@gnu.org>
2430 * sfm-private.h: Get rid of #defines after #error, which makes no
2433 Sat Apr 15 19:48:57 2006 Ben Pfaff <blp@gnu.org>
2435 Get rid of our own int32 type in favor of the standard int32_t
2438 * sfm-private.h: (int32 macro) Don't define this anymore. Do
2441 * sys-file-reader.c: Use int32_t instead of int32 throughout.
2443 * sys-file-writer.c: Use int32_t instead of int32 throughout.
2445 Sat Apr 15 19:36:47 2006 Ben Pfaff <blp@gnu.org>
2447 Remove ill-considered file routines that are no longer used.

2463 Tue Mar 28 13:47:16 WST 2006 John Darrington <john@darrington.wattle.id.au>
2465 * filename.[ch] (fn_interp_vars): Changed the signature and semantics
2466 so as to modify the string inline. Thus makeing it easier to
2467 destroy the results when no longer needed.
2469 2006-03-25 Jason Stover <jhs@math.gcsu.edu>
2471 * category.c (cat_stored_values_destroy): Fixed memory leak.
2473 Fri Mar 24 18:15:41 2006 Ben Pfaff <blp@gnu.org>

2494 * value.h: Remove check on MAX_SHORT_STRING, which I don't think
2497 * variable.h: Move definition of SHORT_NAME_LEN, LONG_NAME_LEN
2498 here from pref.h.orig.
