153 Suggested by Chusslove Illich <caslav.ilic@gmx.net>.
155 2007-11-03 Ben Pfaff <blp@gnu.org>
157 Allow output files to overwrite input files (bug #21280).
159 * file-handle-def.c: Separate locking of files for input and for
160 output, to allow both to take place at once. Also, distinguish a

257 * data-out.c (output_number): Use isfinite (from C99) instead of
258 gsl_isfinite, since we now have universal support for it in
260 (output_infinite): Ditto.
261 [!HAVE_ROUND] (round): Remove definition, since we now have a
262 replacement in gnulib.
264 2007-10-27 John Darrington <john@darrington.wattle.id.au>

512 Improvements to system file reader and writer.
514 First, move all detailed knowledge of very long strings into
515 sys-file-private.[ch], so that this nasty stuff can be isolated.

531 (EFFECTIVE_LONG_STRING_LENGTH): Removed.
532 (struct sfm_var): New structure.
534 Next, improvements to the system file reader.
536 * sys-file-reader.h (struct sfm_read_info): Changed `case_cnt' to
537 type casenumber. Added `version_major', `version_minor',
540 * sys-file-reader.c (struct sfm_reader): Replaced `flt64_cnt' by
541 `oct_cnt'. Rename `vars', `var_cnt' to `sfm_vars', `sfm_var_cnt'.
542 Change `case_cnt' to type casenumber. Removed `has_vls'.
543 (struct sfm_var): Removed.
544 (sfm_open_reader): Don't warn on wrong case size if the file was
545 written by SPSS 13, which tends to get it wrong. Use
546 sfm_dictionary_to_sfm_vars.
547 (read_header): Always output system file info.
548 (read_variable_record): Simplify code for reading missing values.
549 (read_machine_int32_info): Save version numbers from system file
550 into info struct passed as new argument.
551 (read_long_string_map): Restructured to use new sys-file-private
553 (read_value_labels): Use size_overflow_p.
554 (sys_file_casereader_read): Get rid of distinction between fast

564 (flt64_to_double): Removed. Changed callers to use float_convert.
566 Finally, get rid of int32, flt64 terminology and types in system
567 file writer. The former wasn't very useful since a POSIX "int"
568 can hold the whole range of int32 and we generally didn't have a
569 need for it to be exactly-32-bits, just at-least-32-bits. The
570 latter was inconvenient because we had to assume that it could be
571 different from double and thereby convert special values SYSMIS,
572 HIGHEST, LOWEST to and from it in multiple places. Instead, now
573 we just use "int" and "double" in most places, and do conversions,
574 if necessary, very close to where we do I/O. This change meant
575 that the writer code couldn't represent records in the file as C
576 structs any longer, but that's no great loss. The code actually
577 seems to be more readable without them.

805 Until now, the procedure code has provided a case to the
806 case_source, which has filled in the data values that come from
807 the active file. "Left" data values that don't come from the
808 active file naturally stay the same from case to case, because the
809 procedure code keeps using that same case.
811 One of the compromises that comes with the new procedure code is
812 that the active file allocates and provides its own case, which
813 the procedure code then has to resize to provide room for any
814 other variables that should go in the case and then fill in the
815 values of "left" variables. Then, when we're done with that case,
816 we have to save the values of "left" variables to copy into the
817 next case read from the active file.

1073 Thu Feb 1 16:53:37 2007 Ben Pfaff <blp@gnu.org>
1075 We are using a single member in struct file_handle, the "name"
1076 field, for more than one purpose. When it begins with '"', it's a
1077 file name; otherwise, it's a token that can be used to identify
1078 it. When that assertion fires, it's because we searched for the
1079 name case-sensitively as a file name (so that there was no match),
1080 and then we try to insert it case-insensitively as a token, which
1081 fails because duplicates aren't allowed.
1083 Solution: break the two purposes into two separate fields. This
1084 fixes the problem and likely makes the code easier to read too.

1104 reference counting to share data. This makes it easy for

1106 but have been kept around by another user's ref-count. This often
1107 happens when the data set is small enough to find in memory; if a
1108 bigger data set that would overflow to disk were used, then data
1109 corruption would occur.

1200 * missing-values.h (enum mv_class): New type.
1201 (enum mv_type): Moved definition into missing-values.c and renamed

1203 enums. Updated all uses.
1204 (struct missing_values): Changed type of `type' from `enum
1205 mv_type' to `int' because the definition is no longer exposed.

1251 function call, instead of requiring indirection through a callback
1254 * case-source.h (struct case_source_class): Change ->read function
1255 to return a single case, instead of calling a callback function
1256 for each case. Change ->destroy function to return an error

1260 by the case_source ->destroy function.
1262 * procedure.c (struct write_case_data): Removed.
1263 (struct dataset): Added some members to track procedure state.
1264 (procedure): Optimize the trivial case at this level.

1316 the only remaining user. Removed Borland C++-specific directives.
1318 * sys-file-reader.c: Clean up and rewrite entire file. The
1319 rewritten version is simpler and better abstracted, and should be
1320 easier to maintain and extend. It avoids using structures to read
1321 file data, which is prone to padding variations among compilers.
1322 It should also handle non-IEEE 754 system files, although I
1323 haven't been able to find any. It has been tested against many
1324 .sav files obtained from the Web and found to produce the same
1325 results as the earlier version of the code, or in some cases
1326 improved results. It is more tolerant of format variations found
1329 * sys-file-reader.h (struct sfm_read_info): Removed `big_endian'
1330 member, putting an enum integer_format in its place. New member

1344 * format.c (fmt_dollar_template): Use user's decimal point
1345 character. Add assertion.

1349 * format.c (fmt_dollar_template): New function, based on
1350 dollar_format_template from var-type-dialog.c.

1375 use. Updated all callers to use the new interface, or to use the
1376 new *_idx function (see above).
1379 (case_data_rw): Ditto.
1381 * category.c (cat_stored_values_destroy): Changed interface to
1382 take a struct cat_vals * instead of a struct variable *.

1443 (macro EFFECTIVE_LONG_STRING_LENGTH) Moved to sys-file-private.h.
1444 (macro MAX_ELEMS_PER_VALUE) Removed, as it was unused.

1650 (output_scientific) Follow more rational rule on when to drop
1651 fraction introduced between SPSS 13 and 15. Updated test case to

1774 * format.c: (fmt_type_from_string) New function.
1775 (fmt_to_string) Include decimals in output if the format has
1776 decimals, even if the format type does not. This way, we can
1777 accurately reproduce incorrect formats in user output.
1778 (check_common_specifier) Make the check for a bad format type an
1779 assertion, so we get bug reports if they show up. Fix message.

1818 Tue Jul 4 08:47:35 2006 Ben Pfaff <blp@gnu.org>
1820 Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
1821 ALL) and additional underlying system file issues.
1823 Thanks to John Darrington for review.
1825 First problem: var_hash points to variables not owned by the
1826 sys-file-reader, which the caller may free or modify. Use an
1827 array of sfm_vars instead, as done earlier (e.g. CVS version
1830 * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
1831 members and remove all code that references it. Add vars, var_cnt
1832 members. Remove fix_specials member, which was unused.
1833 (struct sfm_var) Remove name member, which was unused.
1834 (sfm_close_reader) Free vars member instead of var_hash.
1835 (compare_var_shortnames) Removed.
1836 (hash_var_shortname) Removed.
1837 (sfm_open_reader) Fill out vars array.
1838 (compare_var_index) Removed.
1839 (sfm_read_case) Use vars instead of var_hash.
1841 Second problem: we're confused about when we actually have very
1842 long strings, causing us to choose incorrectly between slow path
1843 and fast path in sfm_read_case.
1845 * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
1846 have very long strings, not when we have long variable names,
1847 which is an unrelated feature.
1849 Tue Jun 27 12:06:49 2006 Ben Pfaff <blp@gnu.org>
1851 * variable.h: Move var_set and variable parsing declarations to
1852 new header, src/language/lexer/variable-parser.h. Modified lots
1853 of files to include the new header.
1855 Sun Jun 25 22:39:32 2006 Ben Pfaff <blp@gnu.org>
1857 * value-labels.c (value_to_string): When there's no value label,
1858 format the variable according to its print format, instead of
1859 always effectively using A or F format.
1861 Mon Jun 19 18:05:42 WST 2006 John Darrington <john@darrington.wattle.id.au>
1863 * casefile.c (casefile_get_random_reader): Nasty hack to get around

1997 Sat May 6 12:38:55 2006 Ben Pfaff <blp@gnu.org>
1999 Continue reforming procedure execution. In this phase, remove
2000 PROCESS IF, which was deprecated anyway and can be easily
2001 simulated with TEMPORARY followed by SELECT IF.
2003 * procedure.c: (open_active_file) Don't call
2004 add_process_if_trns().
2005 (discard_variables) Get rid of redundant call to
2006 proc_cancel_all_transformations().
2007 (add_process_if_trns) Removed.
2008 (process_if_trns_proc) Removed.

2030 Continue reforming procedure execution. In this phase, get rid of
2031 the output code for SPLIT FILE groups in procedure.c, which really
2032 shouldn't be doing any output. Move it into the individual
2033 procedures instead. This also adds some flexibility.
2035 Updated many users of procedure_with_splits() and
2036 multipass_procedure_with_splits() to call
2037 output_split_file_values() and to deal with increased use of
2040 * procedure.c: (struct split_aux_data) Add "const struct ccase *"
2041 parameter to begin_func member.

2057 Fri May 5 22:48:50 2006 Ben Pfaff <blp@gnu.org>
2059 Continue reforming procedure execution. Change
2060 internal_procedure() so that it calls open_active_file() and

2065 to `case_func' and update all references.
2066 (procedure) Rewrite as one-line wrapper around

2142 * data-out.c, data-in.c, variable.c, variable.h: New functions
2143 copy_mangle and copy_demangle for reading/writing cases; emulates the
2144 way SPSS deals with strings > 255 bytes.

2150 instead of literal values. Also fixed some constness issues.
2152 * format.h: Constness
2154 * sfm-private.h: Renamed the case_size identifier, since I discovered
2155 that SPSS's respect for this variable is very nominal.

2192 * variable.h: (struct variable) Remove `init' member and all
2193 references to it from other files. It was initialized in several
2194 places, but nothing really ever used it for anything worthwhile.
2195 Thanks to Jason Stover for pointing out how confusing this
2198 Sun Apr 23 22:04:45 2006 Ben Pfaff <blp@gnu.org>
2200 Continue reforming error message support. In this phase, get rid
2201 of message "titles" and put the message text in `struct error'.
2202 Now `struct error' encapsulates a message more properly.
2204 * casefile.c: (io_error) Use err_msg() instead of err_vmsg().
2205 Format message ourselves.
2207 * data-in.c: (vdls_error) Ditto.

2211 * sys-file-reader.c: (corrupt_msg) Ditto.
2213 Sun Apr 16 18:49:51 2006 Ben Pfaff <blp@gnu.org>
2215 GNU standards require "file name" instead of "filename" in

2220 `file_name'. Updated all references.
2222 * file-name.c: [!unix] (struct file_identity) Rename
2223 normalized_filename member to normalized_file_name. Updated all
2226 Sun Apr 16 18:35:33 2006 Ben Pfaff <blp@gnu.org>
2228 We don't really support anything but Unix-like environments well,
2229 so we might as well de-obfuscate by writing directory and path
2230 separators explicitly.
2232 * file-name.h: (macro DIR_SEPARATOR) Removed. Changed all usages
2234 (macro PATH_SEPARATOR) Removed. Changed all usages to just ':'.
