217 Allow output files to overwrite input files (bug #21280).
219 * file-handle-def.c: Separate locking of files for input and for
220 output, to allow both to take place at once. Also, distinguish a

591 (EFFECTIVE_LONG_STRING_LENGTH): Removed.
592 (struct sfm_var): New structure.
594 Next, improvements to the system file reader.
596 * sys-file-reader.h (struct sfm_read_info): Changed `case_cnt' to
597 type casenumber. Added `version_major', `version_minor',
600 * sys-file-reader.c (struct sfm_reader): Replaced `flt64_cnt' by
601 `oct_cnt'. Rename `vars', `var_cnt' to `sfm_vars', `sfm_var_cnt'.
602 Change `case_cnt' to type casenumber. Removed `has_vls'.
603 (struct sfm_var): Removed.
604 (sfm_open_reader): Don't warn on wrong case size if the file was
605 written by SPSS 13, which tends to get it wrong. Use
606 sfm_dictionary_to_sfm_vars.
607 (read_header): Always output system file info.
608 (read_variable_record): Simplify code for reading missing values.
609 (read_machine_int32_info): Save version numbers from system file
610 into info struct passed as new argument.
611 (read_long_string_map): Restructured to use new sys-file-private
613 (read_value_labels): Use size_overflow_p.
614 (sys_file_casereader_read): Get rid of distinction between fast
615 and slow paths. Use information provided by sys-file-primate's
616 struct sfm_var to simplify code.
617 (skip_whole_strings): New function.
618 (read_int32): Renamed read_int. Changed return value to int.
620 (read_flt64): Renamed read_float. Changed return value to
621 double. Updated all callers.
622 (int32_to_native): Removed. Changed callers to use
624 (flt64_to_double): Removed. Changed callers to use float_convert.
626 Finally, get rid of int32, flt64 terminology and types in system
627 file writer. The former wasn't very useful since a POSIX "int"
628 can hold the whole range of int32 and we generally didn't have a
629 need for it to be exactly-32-bits, just at-least-32-bits. The
630 latter was inconvenient because we had to assume that it could be
631 different from double and thereby convert special values SYSMIS,
632 HIGHEST, LOWEST to and from it in multiple places. Instead, now
633 we just use "int" and "double" in most places, and do conversions,
634 if necessary, very close to where we do I/O. This change meant
635 that the writer code couldn't represent records in the file as C
636 structs any longer, but that's no great loss. The code actually
637 seems to be more readable without them.
639 Simplify the compression buffering code: only buffer as much as
640 necessary, which is no more than eight 8-byte units at any given

646 (struct sysfile_variable): Removed.
647 (struct sfm_writer): Removed `needs_translation', `has_vls',

649 type casenumber. Renamed `vars' to `sfm_vars', `var_cnt' to
650 `sfm_var_cnt'. Replaced `buf', `end', `ptr', `x', `y' for
651 compression buffering by `opcodes', `opcode_cnt', `data',
652 `data_cnt'. Renamed `var_cnt_vls' as `segment_cnt'.

654 data writer functions instead of structures.

865 Until now, the procedure code has provided a case to the
866 case_source, which has filled in the data values that come from
867 the active file. "Left" data values that don't come from the
868 active file naturally stay the same from case to case, because the
869 procedure code keeps using that same case.
871 One of the compromises that comes with the new procedure code is
872 that the active file allocates and provides its own case, which
873 the procedure code then has to resize to provide room for any
874 other variables that should go in the case and then fill in the
875 values of "left" variables. Then, when we're done with that case,
876 we have to save the values of "left" variables to copy into the
877 next case read from the active file.

1135 We are using a single member in struct file_handle, the "name"
1136 field, for more than one purpose. When it begins with '"', it's a
1137 file name; otherwise, it's a token that can be used to identify
1138 it. When that assertion fires, it's because we searched for the
1139 name case-sensitively as a file name (so that there was no match),
1140 and then we try to insert it case-insensitively as a token, which
1141 fails because duplicates aren't allowed.
1143 Solution: break the two purposes into two separate fields. This
1144 fixes the problem and likely makes the code easier to read too.

1167 happens when the data set is small enough to find in memory; if a
1168 bigger data set that would overflow to disk were used, then data
1169 corruption would occur.

1182 counting at some point. Now, I'm pretty sure that it's here to
1183 stay. Thus, because we have to store the value_cnt anyway for
1184 reference-counted cases, we might as well expose it to users.
1186 * case.c (case_get_value_cnt): New function.
1187 (case_resize): Drop OLD_CNT argument. Update all callers. Only
1188 resize case if its size actually changed.
1190 * casefile.c (casefile_append_xfer): Use case_get_value_cnt
1191 instead of peeking inside struct case directly.
1192 (casefile_append): Ditto.
1194 Mon Jan 15 10:50:22 2007 Ben Pfaff <blp@gnu.org>
1196 Get rid of the inlines for the case functions, which made the
1197 header file hard to read. (Also, in testing with "-O2 -DNDEBUG",
1198 the inlines didn't speed up "make check" at all, which is not a
1199 perfect benchmark but seems indicative.)
1201 * case.c: Remove #ifdef DEBUGGING...#endif around many function
1202 definitions. Remove some assertions on nonnull pointers that were
1203 redundant with a pointer dereference soon after in the function.
1205 (struct case_data): Move definition here from case.h.
1209 (case_data_wr): Ditto.
1211 Sun Jan 14 21:41:12 2007 Ben Pfaff <blp@gnu.org>
1213 * automake.mk: Add casedeque.h to sources.
1215 * casedeque.h: New file.
1217 * procedure.c: (struct dataset) Change lag_count, lag_head,
1218 lag_queue member into single struct casedeque member. Update all
1219 users to use the casedeque instead.
1222 Sun Jan 14 21:43:12 2007 Ben Pfaff <blp@gnu.org>
1224 * procedure.c: Simplify lagged cases interface. Updated all
1225 clients--well, the only client--to use the simplified interface.
1226 (dataset_n_lag) Removed.
1227 (dataset_set_n_lag) Removed.
1228 (dataset_need_lag) New function.
1230 Tue Jan 9 07:20:05 WST 2007 John Darrington <john@darrington.wattle.id.au>
1232 * dictionary.c procedure.c: More changes to ensure that callbacks occur
1233 whenever appropriate, but only when the dataset/dictionary is in a
1236 Sun Jan 7 08:33:04 WST 2007 John Darrington <john@darrington.wattle.id.au>
1238 * dictionary.c dictionary.h : Added callbacks for change of filter and
1239 split variables. Refactored some code to ensure that callbacks get
1240 invoked when appropriate.
1242 * procedure.c (proc_cancel_temporary_transformations): Make sure that
1243 replace_dict callback occurs when permanent_dict replaces the current
1246 Wed Jan 3 11:02:11 WST 2007 John Darrington <john@darrington.wattle.id.au>
1248 * dictionary.c dictionary.h : Added callback for when the weight
1249 variable of a dictionary changes.
1251 Mon Jan 1 10:36:26 WST 2007 John Darrington <john@darrington.wattle.id.au>
1253 * dictionary.c dictionary.h : Added replace_source and replace_dict
1254 callbacks, and functions to deal with them.
1256 Fri Dec 22 13:56:08 2006 Ben Pfaff <blp@gnu.org>
1258 Simplify missing value handling.
1260 * missing-values.h (enum mv_class): New type.
1261 (enum mv_type): Moved definition into missing-values.c and renamed
1262 each MV_* to MVT_*, to distinguish them from the exposed mv_class
1263 enums. Updated all uses.
1264 (struct missing_values): Changed type of `type' from `enum
1265 mv_type' to `int' because the definition is no longer exposed.
1267 * missing-values.c (mv_is_value_missing): Add new enum mv_class
1268 parameter. Update all callers.
1269 (mv_is_num_missing): Ditto.
1270 (mv_is_str_missing): Ditto.

1280 (mv_clear): New function.
1282 * variable.c (var_is_value_missing): Add new enum mv_class
1283 parameter. Update all callers.
1284 (var_is_num_missing): Ditto.
1285 (var_is_str_missing): Ditto.
1286 (var_is_value_user_missing): Removed. Changed callers to use
1287 var_is_value_missing.
1288 (var_is_num_user_missing): Removed. Changed callers to use
1290 (var_is_str_user_missing): Removed. Changed callers to use
1292 (var_is_value_system_missing): Removed. Changed callers to use
1293 var_is_value_missing.
1295 * casefilter.c (struct casefilter): Use enum mv_class in place of
1297 (casefilter_variable_missing): Adapt to new member.
1298 (casefilter_create): Change signature to take enum mv_class,
1301 Fri Dec 22 20:08:38 WST 2006 John Darrington <john@darrington.wattle.id.au>
1303 * casefile-factory.h fastfile-factory.c fastfile-factory.h: New files.
1305 * case-sink.c case-sink.h procedure.c procedure.h
1306 storage-stream.c: Now uses the factory.
1308 Sat Dec 16 22:05:18 2006 Ben Pfaff <blp@gnu.org>
1310 Make it possible to pull cases from the active file with a
1311 function call, instead of requiring indirection through a callback
1314 * case-source.h (struct case_source_class): Change ->read function
1315 to return a single case, instead of calling a callback function
1316 for each case. Change ->destroy function to return an error
1319 * case-source.c (free_case_source): Pass along the value returned
1320 by the case_source ->destroy function.
1322 * procedure.c (struct write_case_data): Removed.
1323 (struct dataset): Added some members to track procedure state.
1324 (procedure): Optimize the trivial case at this level.
1325 (internal_procedure): Re-implement in terms of proc_open,
1326 proc_read, proc_close.
1327 (proc_open) New function.
1328 (proc_read) New function.
1329 (proc_close) New function.
1330 (write_case) Moved into proc_read.
1331 (close_active_file) Moved closing of data source into proc_close.
1333 * storage-source.c: Rewrote to conform with modified
1334 case_source_class interface.
1336 * transformations.c (trns_chain_execute): Added argument to allow
1337 starting execution from an arbitrary transformation. Updated
1340 * transformations.h (enum TRNS_NEXT_CASE) Renamed TRNS_END_CASE.
1342 Sat Dec 16 14:09:25 2006 Ben Pfaff <blp@gnu.org>
1344 * sys-file-reader.c (read_display_parameters): Don't assume that
1345 MEASURE_* and ALIGN_* have the same values found in system files.
1347 * sys-file-writer.c (write_variable_display_parameters): Ditto.
1349 * variable.h: Change MEASURE_NOMINAL, MEASURE_ORDINAL,
1350 MEASURE_SCALE to be 0-based instead of 1-based. This also fixes
1351 the value of n_MEASURES, which was off by 1 (at least from my
1354 Sat Dec 16 12:17:34 WST 2006 John Darrington <john@darrington.wattle.id.au>
1356 * dictionary.c dictionary.h vardict.h variable.c: Added optional
1357 callbacks which are invoked when the dictionary or its
1358 variables are changed.
1360 * missing-values.c missing-values.h value-labels.c: Tidied up
1361 consistency checks, and made some of them return false
1362 instead of assert-failing.
1364 Wed Dec 13 19:30:11 2006 Ben Pfaff <blp@gnu.org>
1366 * calendar.c (calendar_days_in_month): New function.

1370 * value-labels.c (hash_int_val_lab): Only hash as many bytes as
1371 the value label's width.
1373 Sun Dec 10 14:21:29 2006 Ben Pfaff <blp@gnu.org>
1375 * sfm-private.h: Move contents into sys-file-writer.c, which is
1376 the only remaining user. Removed Borland C++-specific directives.
1378 * sys-file-reader.c: Clean up and rewrite entire file. The
1379 rewritten version is simpler and better abstracted, and should be
1380 easier to maintain and extend. It avoids using structures to read
1381 file data, which is prone to padding variations among compilers.
1382 It should also handle non-IEEE 754 system files, although I
1383 haven't been able to find any. It has been tested against many
1384 .sav files obtained from the Web and found to produce the same
1385 results as the earlier version of the code, or in some cases
1386 improved results. It is more tolerant of format variations found
1389 * sys-file-reader.h (struct sfm_read_info): Removed `big_endian'
1390 member, putting an enum integer_format in its place. New member
1391 `float_format'. Changed `compressed' member to type bool.
1393 Sun Dec 10 13:48:53 2006 Ben Pfaff <blp@gnu.org>
1395 * dictionary.c (dict_delete_consecutive_vars): New function.
1397 Sat Dec 9 20:08:25 2006 Ben Pfaff <blp@gnu.org>
1399 * file-name.c (fn_search_path): Remove prefix arg that was unused
1400 by any caller. Updated all callers.
1402 Sat Dec 9 20:04:22 2006 Ben Pfaff <blp@gnu.org>
1404 * format.c (fmt_dollar_template): Use user's decimal point
1405 character. Add assertion.
1407 Sat Dec 9 20:02:25 2006 Ben Pfaff <blp@gnu.org>
1409 * format.c (fmt_dollar_template): New function, based on
1410 dollar_format_template from var-type-dialog.c.
1412 Sat Dec 9 18:05:59 2006 Ben Pfaff <blp@gnu.org>
1414 * data-out.c (output_scientific): Fix bad assumption that "buf" is
1417 Sat Dec 9 17:23:23 2006 Ben Pfaff <blp@gnu.org>
1419 Finish converting struct variable to an opaque type. In this
1420 phase, we add remaining setter and getter functions, convert the
1421 remaining PSPP code to use them, and do a bunch of cleanup. The

1434 that takes a variable instead of an index, which is easier to
1435 use. Updated all callers to use the new interface, or to use the
1436 new *_idx function (see above).
1439 (case_data_rw): Ditto.
1441 * category.c (cat_stored_values_destroy): Changed interface to
1442 take a struct cat_vals * instead of a struct variable *.

1465 (dict_clear_vectors) Use new vector_destroy function.
1466 (set_var_short_name_suffix) Move here from variable.c, renamed
1467 from var_set_short_name_suffix, make static, update caller.
1469 * sys-file-private.c: New file.
1470 (sfm_width_to_bytes) Moved here from variable.c, renamed from
1471 width_to_bytes, update callers.
1473 * sys-file-private.h: New file. Later it will supplant
1474 sfm-private.h; for now it supplements it.
1475 (macro MIN_VERY_LONG_STRING) New macro.
1476 (macro EFFECTIVE_LONG_STRING_LENGTH) New macro, from value.h.
1478 * sys-file-reader.c: Use MIN_VERY_LONG_STRING - 1 where
1479 MAX_LONG_STRING was used before.
1481 * sys-file-writer.c: Ditto.
1483 * value-labels.c: Change the paradigm here to be that a null
1484 pointer is OK for a struct val_labs * in most cases; it just
1485 represents an empty set of value labels.
1486 (val_labs_copy) A copy of a null set is a null set.
1487 (val_labs_count) A null set has 0 labels.

1496 (compare_values) Ditto.
1499 * value.h: (macro MAX_SHORT_STRING) Rewrote for simplicity.

1501 for system files, not for general code.
1502 (macro MAX_VERY_LONG_STRING) Ditto.
1503 (macro EFFECTIVE_LONG_STRING_LENGTH) Moved to sys-file-private.h.
1504 (macro MAX_ELEMS_PER_VALUE) Removed, as it was unused.
1506 * vardict.h: New file, for an interface between variables and
1509 * variable.c: A lot of functions were moved around, for better
1511 (struct variable) Move definition here, from variable.h.

1526 as long as we can resize it. Simplify callers who were doing the
1527 resizing themselves.

1648 (var_get_leave) New function.
1649 (var_get_short_name) New function.
1651 * variable.h: (struct variable) Removed "type" and "nv" members;
1652 they are now computed from "width" where needed.
1654 Mon Dec 4 21:38:40 2006 Ben Pfaff <blp@gnu.org>
1656 * missing-values.c (mv_resize): Don't write beyond end of the
1657 allocated buffer when resizing a long string.
1659 Sat Dec 2 16:28:32 2006 Ben Pfaff <blp@gnu.org>
1661 Clean up identifier code: don't require identifier enumerations to
1662 be in a particular order; make better use of string library;
1663 expose less of the internals.
1665 * identifier.c: (lex_skip_identifier) Rename lex_id_get_length,
1666 change interface. Updated all callers.
1667 (lex_id_match) Change interface to use struct substring, update
1669 (lex_id_match_len) Removed. Update callers to use lex_id_match.
1670 (global array keywords[]) Make static, change form. Update all
1671 users to use lex_id_name instead.

1673 (lex_id_to_token) Change interface to use struct substring, update
1675 (lex_id_name) New function.

1678 lex_is_keyword instead.
1679 (T_LAST_KEYWORD) Removed.
1680 (T_N_KEYWORDS) Removed.
1682 Sat Nov 18 20:46:35 2006 Ben Pfaff <blp@gnu.org>
1684 * format.c: (fmt_date_template) Distinguish characters for which a
1685 space is output and any date delimiter is allowed on input, from
1686 those for which a space is output and only a space is allowed on
1687 input. The former is represented by X, the latter by a space.
1688 Also, drop distinction between h and H, changing the former to the
1691 * data-in.c: Completely rewrite internals to conform to SPSS input
1692 formats as closely as possible.
1693 (data_in) Changed external interface by replacing the structure
1694 that was used as a single argument by a set of arguments. Updated

1880 Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
1881 ALL) and additional underlying system file issues.
1883 Thanks to John Darrington for review.
1885 First problem: var_hash points to variables not owned by the
1886 sys-file-reader, which the caller may free or modify. Use an
1887 array of sfm_vars instead, as done earlier (e.g. CVS version
1890 * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
1891 members and remove all code that references it. Add vars, var_cnt
1892 members. Remove fix_specials member, which was unused.

1898 (compare_var_index) Removed.
1899 (sfm_read_case) Use vars instead of var_hash.
1901 Second problem: we're confused about when we actually have very
1902 long strings, causing us to choose incorrectly between slow path
1903 and fast path in sfm_read_case.
1905 * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
1906 have very long strings, not when we have long variable names,
1907 which is an unrelated feature.
1909 Tue Jun 27 12:06:49 2006 Ben Pfaff <blp@gnu.org>
1911 * variable.h: Move var_set and variable parsing declarations to
1912 new header, src/language/lexer/variable-parser.h. Modified lots
1913 of files to include the new header.
1915 Sun Jun 25 22:39:32 2006 Ben Pfaff <blp@gnu.org>
1917 * value-labels.c (value_to_string): When there's no value label,
1918 format the variable according to its print format, instead of
1919 always effectively using A or F format.

2064 add_process_if_trns().
2065 (discard_variables) Get rid of redundant call to

2092 shouldn't be doing any output. Move it into the individual
2093 procedures instead. This also adds some flexibility.
2095 Updated many users of procedure_with_splits() and
2096 multipass_procedure_with_splits() to call

2119 Continue reforming procedure execution. Change
2120 internal_procedure() so that it calls open_active_file() and

2253 references to it from other files. It was initialized in several
2254 places, but nothing really ever used it for anything worthwhile.
2255 Thanks to Jason Stover for pointing out how confusing this
2258 Sun Apr 23 22:04:45 2006 Ben Pfaff <blp@gnu.org>
2260 Continue reforming error message support. In this phase, get rid
2261 of message "titles" and put the message text in `struct error'.
2262 Now `struct error' encapsulates a message more properly.
2264 * casefile.c: (io_error) Use err_msg() instead of err_vmsg().
2265 Format message ourselves.
2267 * data-in.c: (vdls_error) Ditto.
2269 * por-file-reader.c: (error) Ditto.
2271 * sys-file-reader.c: (corrupt_msg) Ditto.
2273 Sun Apr 16 18:49:51 2006 Ben Pfaff <blp@gnu.org>
2275 GNU standards require "file name" instead of "filename" in
2276 documentation. It's nice for our code to follow the convention
2279 * casefile.c: (struct casefile) Rename `filename' member to
2280 `file_name'. Updated all references.
2282 * file-name.c: [!unix] (struct file_identity) Rename
2283 normalized_filename member to normalized_file_name. Updated all
2286 Sun Apr 16 18:35:33 2006 Ben Pfaff <blp@gnu.org>
2288 We don't really support anything but Unix-like environments well,
2289 so we might as well de-obfuscate by writing directory and path
2290 separators explicitly.
2292 * file-name.h: (macro DIR_SEPARATOR) Removed. Changed all usages
2294 (macro PATH_SEPARATOR) Removed. Changed all usages to just ':'.
2295 (macro DIR_SEPARATOR_STRING) Removed. Changed all usages to just
2297 (macro PATH_SEPARATOR_STRING) Removed. Changed all usages to just
2300 Sun Apr 16 18:28:35 2006 Ben Pfaff <blp@gnu.org>
2302 GNU standards require "file name" instead of "filename" in
2303 documentation. It's nice for our code to follow the convention
2306 * filename.c: Rename to file-name.c.
2308 * filename.h: Rename to file-name.h. Update all inclusions.
2309 Update header guards.
2311 * automake.mk: Update file names.
2313 Sun Apr 16 16:42:47 2006 Ben Pfaff <blp@gnu.org>
2315 * filename.c: (fn_dirname) Renamed fn_dir_name(), all references
2317 (fn_basename) Removed (dead code).
2318 (fn_absolute_p) Renamed fn_is_absolute(), all references updated.
2319 (fn_special_p) Renamed fn_is_special(), all references updated.
2320 (fn_exists_p) Renamed fn_exists(), all references updated.
2322 Sun Apr 16 16:33:58 2006 Ben Pfaff <blp@gnu.org>
2324 * filename.c: (fn_tilde_expand) Rewrite for cleaner code.
2325 Also, now it only tilde-expands file names, not paths.
2326 (fn_search_path) Tilde-expand one directory at a time.
2328 Sun Apr 16 16:28:06 2006 Ben Pfaff <blp@gnu.org>
2330 * filename.c: (fn_search_path) rewrite for cleaner code. Also,
2331 get rid of non-Unixlike version of the code, which has probably
2333 (fn_prepend_dir) Removed (dead code).
2335 * filename.h: (macro DIR_SEPARATOR_STRING) New.
2336 (macro PATH_SEPARATOR_STRING) New.
2337 Sun Apr 16 16:05:28 2006 Ben Pfaff <blp@gnu.org>
2339 Continue reforming error message support. In this phase, we get
2340 rid of VM() and the other msg() support for "verbosity", replacing
2341 it by a new function verbose_msg().
2343 * filename.c: (fn_search_path) Use verbose_msg() instead of
2346 Sat Apr 15 19:53:19 2006 Ben Pfaff <blp@gnu.org>
2348 * sfm-private.h: Get rid of #defines after #error, which makes no
2351 Sat Apr 15 19:48:57 2006 Ben Pfaff <blp@gnu.org>
2353 Get rid of our own int32 type in favor of the standard int32_t
2356 * sfm-private.h: (int32 macro) Don't define this anymore. Do
2359 * sys-file-reader.c: Use int32_t instead of int32 throughout.
2361 * sys-file-writer.c: Use int32_t instead of int32 throughout.
2363 Sat Apr 15 19:36:47 2006 Ben Pfaff <blp@gnu.org>
2365 Remove ill-considered file routines that are no longer used.
2367 * filename.c: (fn_open_ext) Removed.
2368 (fn_close_ext) Removed.
2370 * filename.h: (struct file_ext) Removed.
2372 Mon Apr 3 13:22:39 2006 Ben Pfaff <blp@gnu.org>
2374 * variable.c (var_is_valid_name): Move declarations before code
2377 Tue Apr 4 15:28:40 WST 2006 John Darrington <john@darrington.wattle.id.au>
2379 * filename.ch (fn_interp_vars): Fixed small buglet.
2381 Tue Mar 28 13:47:16 WST 2006 John Darrington <john@darrington.wattle.id.au>
2383 * filename.[ch] (fn_interp_vars): Changed the signature and semantics
2384 so as to modify the string inline. Thus makeing it easier to
2385 destroy the results when no longer needed.
2387 2006-03-25 Jason Stover <jhs@math.gcsu.edu>
2389 * category.c (cat_stored_values_destroy): Fixed memory leak.
2391 Fri Mar 24 18:15:41 2006 Ben Pfaff <blp@gnu.org>
2393 Add some missing frees. Thanks to John Darrington for reporting
2396 * any-writer.c (any_writer_close): Free writer.
2398 * any-reader.c (any_reader_close): Free reader.
2400 Mon Mar 20 16:33:53 2006 Ben Pfaff <blp@gnu.org>
2402 * por-file-reader.c: (error) Mark as NO_RETURN.
2404 Sat Mar 11 15:06:07 WST 2006 John Darrington <john@darrington.wattle.id.au>
2406 * settings.c: Changed default value of scompress to true.
2408 Sat Mar 4 13:22:51 2006 Ben Pfaff <blp@gnu.org>
2410 * sfm-private.h: Include variable.h, to get SHORT_NAME_LEN.
2412 * value.h: Remove check on MAX_SHORT_STRING, which I don't think
2415 * variable.h: Move definition of SHORT_NAME_LEN, LONG_NAME_LEN
2416 here from pref.h.orig.
2418 Sat Mar 4 12:50:48 WST 2006 John Darrington <john@darrington.wattle.id.au>
2420 * sys-file-reader.c: Fixed bug reading compressed files.
2422 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
2424 * Numerous renames. See src/ChangeLog for details.
2426 * Moved files from src directory
