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

582 double. Updated all callers.
583 (int32_to_native): Removed. Changed callers to use
585 (flt64_to_double): Removed. Changed callers to use float_convert.
587 Finally, get rid of int32, flt64 terminology and types in system
588 file writer. The former wasn't very useful since a POSIX "int"
589 can hold the whole range of int32 and we generally didn't have a
590 need for it to be exactly-32-bits, just at-least-32-bits. The
591 latter was inconvenient because we had to assume that it could be
592 different from double and thereby convert special values SYSMIS,
593 HIGHEST, LOWEST to and from it in multiple places. Instead, now
594 we just use "int" and "double" in most places, and do conversions,
595 if necessary, very close to where we do I/O. This change meant
596 that the writer code couldn't represent records in the file as C
597 structs any longer, but that's no great loss. The code actually
598 seems to be more readable without them.

826 Until now, the procedure code has provided a case to the
827 case_source, which has filled in the data values that come from
828 the active file. "Left" data values that don't come from the
829 active file naturally stay the same from case to case, because the
830 procedure code keeps using that same case.
832 One of the compromises that comes with the new procedure code is
833 that the active file allocates and provides its own case, which
834 the procedure code then has to resize to provide room for any
835 other variables that should go in the case and then fill in the
836 values of "left" variables. Then, when we're done with that case,
837 we have to save the values of "left" variables to copy into the
838 next case read from the active file.

1094 Thu Feb 1 16:53:37 2007 Ben Pfaff <blp@gnu.org>
1096 We are using a single member in struct file_handle, the "name"
1097 field, for more than one purpose. When it begins with '"', it's a
1098 file name; otherwise, it's a token that can be used to identify
1099 it. When that assertion fires, it's because we searched for the
1100 name case-sensitively as a file name (so that there was no match),
1101 and then we try to insert it case-insensitively as a token, which
1102 fails because duplicates aren't allowed.
1104 Solution: break the two purposes into two separate fields. This
1105 fixes the problem and likely makes the code easier to read too.

1128 happens when the data set is small enough to find in memory; if a
1129 bigger data set that would overflow to disk were used, then data
1130 corruption would occur.

1194 whenever appropriate, but only when the dataset/dictionary is in a
1197 Sun Jan 7 08:33:04 WST 2007 John Darrington <john@darrington.wattle.id.au>
1199 * dictionary.c dictionary.h : Added callbacks for change of filter and
1200 split variables. Refactored some code to ensure that callbacks get
1201 invoked when appropriate.
1203 * procedure.c (proc_cancel_temporary_transformations): Make sure that
1204 replace_dict callback occurs when permanent_dict replaces the current
1207 Wed Jan 3 11:02:11 WST 2007 John Darrington <john@darrington.wattle.id.au>
1209 * dictionary.c dictionary.h : Added callback for when the weight

1221 * missing-values.h (enum mv_class): New type.
1222 (enum mv_type): Moved definition into missing-values.c and renamed

1224 enums. Updated all uses.
1225 (struct missing_values): Changed type of `type' from `enum
1226 mv_type' to `int' because the definition is no longer exposed.

1272 function call, instead of requiring indirection through a callback
1275 * case-source.h (struct case_source_class): Change ->read function
1276 to return a single case, instead of calling a callback function
1277 for each case. Change ->destroy function to return an error

1281 by the case_source ->destroy function.
1283 * procedure.c (struct write_case_data): Removed.

1337 the only remaining user. Removed Borland C++-specific directives.
1339 * sys-file-reader.c: Clean up and rewrite entire file. The
1340 rewritten version is simpler and better abstracted, and should be
1341 easier to maintain and extend. It avoids using structures to read
1342 file data, which is prone to padding variations among compilers.
1343 It should also handle non-IEEE 754 system files, although I
1344 haven't been able to find any. It has been tested against many
1345 .sav files obtained from the Web and found to produce the same
1346 results as the earlier version of the code, or in some cases
1347 improved results. It is more tolerant of format variations found
1350 * sys-file-reader.h (struct sfm_read_info): Removed `big_endian'
1351 member, putting an enum integer_format in its place. New member
1352 `float_format'. Changed `compressed' member to type bool.

1361 by any caller. Updated all callers.
1363 Sat Dec 9 20:04:22 2006 Ben Pfaff <blp@gnu.org>
1365 * format.c (fmt_dollar_template): Use user's decimal point
1366 character. Add assertion.
1368 Sat Dec 9 20:02:25 2006 Ben Pfaff <blp@gnu.org>
1370 * format.c (fmt_dollar_template): New function, based on
1371 dollar_format_template from var-type-dialog.c.
1373 Sat Dec 9 18:05:59 2006 Ben Pfaff <blp@gnu.org>

1396 use. Updated all callers to use the new interface, or to use the
1397 new *_idx function (see above).
1400 (case_data_rw): Ditto.
1402 * category.c (cat_stored_values_destroy): Changed interface to
1403 take a struct cat_vals * instead of a struct variable *.

1446 represents an empty set of value labels.
1447 (val_labs_copy) A copy of a null set is a null set.
1448 (val_labs_count) A null set has 0 labels.

1463 (macro MAX_VERY_LONG_STRING) Ditto.
1464 (macro EFFECTIVE_LONG_STRING_LENGTH) Moved to sys-file-private.h.
1465 (macro MAX_ELEMS_PER_VALUE) Removed, as it was unused.
1467 * vardict.h: New file, for an interface between variables and

1670 Also, handle new X template character.
1671 (output_scientific) Follow more rational rule on when to drop
1672 fraction introduced between SPSS 13 and 15. Updated test case to
1675 Sat Nov 11 11:41:26 2006 Ben Pfaff <blp@gnu.org>

1795 * format.c: (fmt_type_from_string) New function.
1796 (fmt_to_string) Include decimals in output if the format has
1797 decimals, even if the format type does not. This way, we can
1798 accurately reproduce incorrect formats in user output.
1799 (check_common_specifier) Make the check for a bad format type an
1800 assertion, so we get bug reports if they show up. Fix message.

1839 Tue Jul 4 08:47:35 2006 Ben Pfaff <blp@gnu.org>
1841 Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
1842 ALL) and additional underlying system file issues.
1844 Thanks to John Darrington for review.
1846 First problem: var_hash points to variables not owned by the
1847 sys-file-reader, which the caller may free or modify. Use an
1848 array of sfm_vars instead, as done earlier (e.g. CVS version
1851 * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
1852 members and remove all code that references it. Add vars, var_cnt
1853 members. Remove fix_specials member, which was unused.
1854 (struct sfm_var) Remove name member, which was unused.
1855 (sfm_close_reader) Free vars member instead of var_hash.
1856 (compare_var_shortnames) Removed.
1857 (hash_var_shortname) Removed.
1858 (sfm_open_reader) Fill out vars array.
1859 (compare_var_index) Removed.
1860 (sfm_read_case) Use vars instead of var_hash.
1862 Second problem: we're confused about when we actually have very
1863 long strings, causing us to choose incorrectly between slow path
1864 and fast path in sfm_read_case.
1866 * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
1867 have very long strings, not when we have long variable names,
1868 which is an unrelated feature.
1870 Tue Jun 27 12:06:49 2006 Ben Pfaff <blp@gnu.org>
1872 * variable.h: Move var_set and variable parsing declarations to
1873 new header, src/language/lexer/variable-parser.h. Modified lots
1874 of files to include the new header.
1876 Sun Jun 25 22:39:32 2006 Ben Pfaff <blp@gnu.org>
1878 * value-labels.c (value_to_string): When there's no value label,
1879 format the variable according to its print format, instead of
1880 always effectively using A or F format.
1882 Mon Jun 19 18:05:42 WST 2006 John Darrington <john@darrington.wattle.id.au>
1884 * casefile.c (casefile_get_random_reader): Nasty hack to get around

1953 (procedure_with_splits) Don't initialize case_count.
1954 (split_procedure_case_func) Check whether prev_case is null
1955 instead of case_count.

2018 Sat May 6 12:38:55 2006 Ben Pfaff <blp@gnu.org>
2020 Continue reforming procedure execution. In this phase, remove
2021 PROCESS IF, which was deprecated anyway and can be easily
2022 simulated with TEMPORARY followed by SELECT IF.
2024 * procedure.c: (open_active_file) Don't call
2025 add_process_if_trns().
2026 (discard_variables) Get rid of redundant call to
2027 proc_cancel_all_transformations().
2028 (add_process_if_trns) Removed.
2029 (process_if_trns_proc) Removed.

2051 Continue reforming procedure execution. In this phase, get rid of
2052 the output code for SPLIT FILE groups in procedure.c, which really
2053 shouldn't be doing any output. Move it into the individual
2054 procedures instead. This also adds some flexibility.
2056 Updated many users of procedure_with_splits() and
2057 multipass_procedure_with_splits() to call
2058 output_split_file_values() and to deal with increased use of
2061 * procedure.c: (struct split_aux_data) Add "const struct ccase *"
2062 parameter to begin_func member.

2078 Fri May 5 22:48:50 2006 Ben Pfaff <blp@gnu.org>
2080 Continue reforming procedure execution. Change
2081 internal_procedure() so that it calls open_active_file() and
2082 close_active_file(), which isolates most of the actual procedure
2085 * procedure.c: (struct write_case_data) Rename `proc_func' member
2086 to `case_func' and update all references.
2087 (procedure) Rewrite as one-line wrapper around

2096 of trivial case in here. Move call to open_active_file() and
2097 close_active_file() in here. Now assert that vfm_source is

2127 many global variables, consolidating procedure execution in
2128 procedure.c. Encapsulate transformations in new "struct
2129 trns_chain". Also, change implementation of N OF CASES, FILTER,
2130 and PROCESS IF from special cases to transformations.
2132 * automake.mk: (src_data_libdata_a_SOURCES) Add transformations.c,
2135 * dictionary.c: (global variable default_dict) Move to

2159 statements for C90 compliance.
2161 Tue May 2 10:42:05 WST 2006 John Darrington <john@darrington.wattle.id.au>
2163 * data-out.c, data-in.c, variable.c, variable.h: New functions
2164 copy_mangle and copy_demangle for reading/writing cases; emulates the
2165 way SPSS deals with strings > 255 bytes.
2167 * sys-file-reader.c sys-file-writer.c: Added support for Record 7,
2168 subtype 14 needed for strings longer than 255 bytes.

2171 instead of literal values. Also fixed some constness issues.
2173 * format.h: Constness
2175 * sfm-private.h: Renamed the case_size identifier, since I discovered
2176 that SPSS's respect for this variable is very nominal.
2178 Mon May 1 15:45:42 2006 Ben Pfaff <blp@gnu.org>
2180 Change case limit type from int to size_t.
2182 * dictionary.c: (struct dictionary) Change type of case_limit

2190 and invert sense. Fix up all references.
2192 Wed Apr 26 19:39:28 2006 Ben Pfaff <blp@gnu.org>

2213 * variable.h: (struct variable) Remove `init' member and all
2214 references to it from other files. It was initialized in several
2215 places, but nothing really ever used it for anything worthwhile.
2216 Thanks to Jason Stover for pointing out how confusing this
2219 Sun Apr 23 22:04:45 2006 Ben Pfaff <blp@gnu.org>
2221 Continue reforming error message support. In this phase, get rid
2222 of message "titles" and put the message text in `struct error'.
2223 Now `struct error' encapsulates a message more properly.
2225 * casefile.c: (io_error) Use err_msg() instead of err_vmsg().
2226 Format message ourselves.
2228 * data-in.c: (vdls_error) Ditto.
2230 * por-file-reader.c: (error) Ditto.
2232 * sys-file-reader.c: (corrupt_msg) Ditto.
2234 Sun Apr 16 18:49:51 2006 Ben Pfaff <blp@gnu.org>
2236 GNU standards require "file name" instead of "filename" in
2237 documentation. It's nice for our code to follow the convention
2240 * casefile.c: (struct casefile) Rename `filename' member to
2241 `file_name'. Updated all references.
2243 * file-name.c: [!unix] (struct file_identity) Rename
2244 normalized_filename member to normalized_file_name. Updated all
2247 Sun Apr 16 18:35:33 2006 Ben Pfaff <blp@gnu.org>
2249 We don't really support anything but Unix-like environments well,
2250 so we might as well de-obfuscate by writing directory and path
2251 separators explicitly.
