Next, improvements to the system file reader. * sys-file-reader.h (struct sfm_read_info): Changed `case_cnt' to type casenumber. Added `version_major', `version_minor', `version_revision'. * sys-file-reader.c (struct sfm_reader): Replaced `flt64_cnt' by `oct_cnt'. Rename `vars', `var_cnt' to `sfm_vars', `sfm_var_cnt'. Change `case_cnt' to type casenumber. Removed `has_vls'. (struct sfm_var): Removed. (sfm_open_reader): Don't warn on wrong case size if the file was written by SPSS 13, which tends to get it wrong.

(read_flt64): Renamed read_float. Changed return value to double. Updated all callers. (int32_to_native): Removed. Changed callers to use integer_convert. (flt64_to_double): Removed. Changed callers to use float_convert. Finally, get rid of int32, flt64 terminology and types in system file writer. The former wasn't very useful since a POSIX "int" can hold the whole range of int32 and we generally didn't have a need for it to be exactly-32-bits, just at-least-32-bits. The latter was inconvenient because we had to assume that it could be different from double and thereby convert special values SYSMIS, HIGHEST, LOWEST to and from it in multiple places. Instead, now we just use "int" and "double" in most places, and do conversions, if necessary, very close to where we do I/O. This change meant that the writer code couldn't represent records in the file as C structs any longer, but that's no great loss. The code actually seems to be more readable without them. Simplify the compression buffering code: only buffer as much as necessary, which is no more than eight 8-byte units at any given time. * sys-file-writer.c (typedef flt64): Removed.

"Left" data values that don't come from the active file naturally stay the same from case to case, because the procedure code keeps using that same case. One of the compromises that comes with the new procedure code is that the active file allocates and provides its own case, which the procedure code then has to resize to provide room for any other variables that should go in the case and then fill in the values of "left" variables. Then, when we're done with that case, we have to save the values of "left" variables to copy into the next case read from the active file. The caseinit code helps with this. * automake.mk: Add new files. * caseinit.c: New file. * caseinit.h: New file. 2007-06-06 Ben Pfaff * value.h (value_cnt_from_width): New function. * variable.c (var_get_value_cnt): Use new function. 2007-06-06 Ben Pfaff Add casegrouper, to allow cases read from a given casereader to be broken into groups, each of which has its own casereader.

Thu Feb 1 16:53:37 2007 Ben Pfaff We are using a single member in struct file_handle, the "name" field, for more than one purpose. When it begins with '"', it's a file name; otherwise, it's a token that can be used to identify it. When that assertion fires, it's because we searched for the name case-sensitively as a file name (so that there was no match), and then we try to insert it case-insensitively as a token, which fails because duplicates aren't allowed. Solution: break the two purposes into two separate fields. This fixes the problem and likely makes the code easier to read too. Fixes bug #18922. Thanks to John Darrington for bug report and review. * file-handle-def.c (struct file_handle): New `id' member. (fh_from_name): Rename fh_from_id. Update all callers.

This makes it easy for valgrind, etc. to find accesses to cases that have been destroyed but have been kept around by another user's ref-count. This often happens when the data set is small enough to find in memory; if a bigger data set that would overflow to disk were used, then data corruption would occur. Mon Jan 15 10:55:18 2007 Ben Pfaff Simplify code. * case.c (case_unshare): Make it check internally whether the ref_cnt is greater than 1, so that the callers don't have to. Update callers not to check. Mon Jan 15 10:53:01 2007 Ben Pfaff Before, I was thinking that I might want to get rid of reference counting at some point. Now, I'm pretty sure that it's here to stay. Thus, because we have to store the value_cnt anyway for reference-counted cases, we might as well expose it to users. * case.c (case_get_value_cnt): New function. (case_resize): Drop OLD_CNT argument. Update all callers. Only resize case if its size actually changed. * casefile.c (casefile_append_xfer): Use case_get_value_cnt instead of peeking inside struct case directly. (casefile_append): Ditto. Mon Jan 15 10:50:22 2007 Ben Pfaff Get rid of the inlines for the case functions, which made the header file hard to read. (Also, in testing with "-O2 -DNDEBUG", the inlines didn't speed up "make check" at all, which is not a perfect benchmark but seems indicative.) * case.c: Remove #ifdef DEBUGGING...#endif around many function definitions. Remove some assertions on nonnull pointers that were redundant with a pointer dereference soon after in the function. Also: (struct case_data): Move definition here from case.h. (case_data): Ditto.

Sat Dec 16 22:05:18 2006 Ben Pfaff Make it possible to pull cases from the active file with a function call, instead of requiring indirection through a callback function. * case-source.h (struct case_source_class): Change ->read function to return a single case, instead of calling a callback function for each case. Change ->destroy function to return an error status. * case-source.c (free_case_source): Pass along the value returned by the case_source ->destroy function. * procedure.c (struct write_case_data): Removed.

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

Sat Dec 9 17:23:23 2006 Ben Pfaff Finish converting struct variable to an opaque type. In this phase, we add remaining setter and getter functions, convert the remaining PSPP code to use them, and do a bunch of cleanup.

The former is represented by X, the latter by a space. Also, drop distinction between h and H, changing the former to the latter. * data-in.c: Completely rewrite internals to conform to SPSS input formats as closely as possible. (data_in) Changed external interface by replacing the structure that was used as a single argument by a set of arguments. Updated all callers. (data_in_finite_line) Removed.

Thu Jul 6 19:09:53 2006 Ben Pfaff Fix link error noted by Jason Stover. * storage-stream.c: Include . Tue Jul 4 08:47:35 2006 Ben Pfaff Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support ALL) and additional underlying system file issues. Thanks to John Darrington for review. First problem: var_hash points to variables not owned by the sys-file-reader, which the caller may free or modify. Use an array of sfm_vars instead, as done earlier (e.g. CVS version 1.12). * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars members and remove all code that references it. Add vars, var_cnt members. Remove fix_specials member, which was unused. (struct sfm_var) Remove name member, which was unused. (sfm_close_reader) Free vars member instead of var_hash. (compare_var_shortnames) Removed. (hash_var_shortname) Removed. (sfm_open_reader) Fill out vars array. (compare_var_index) Removed. (sfm_read_case) Use vars instead of var_hash. Second problem: we're confused about when we actually have very long strings, causing us to choose incorrectly between slow path and fast path in sfm_read_case. * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we have very long strings, not when we have long variable names, which is an unrelated feature. Tue Jun 27 12:06:49 2006 Ben Pfaff * variable.h: Move var_set and variable parsing declarations to new header, src/language/lexer/variable-parser.h. Modified lots of files to include the new header. Sun Jun 25 22:39:32 2006 Ben Pfaff * value-labels.c (value_to_string): When there's no value label, format the variable according to its print format, instead of always effectively using A or F format.

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

Fri May 5 22:48:50 2006 Ben Pfaff Continue reforming procedure execution. Change internal_procedure() so that it calls open_active_file() and close_active_file(), which isolates most of the actual procedure functionality. * procedure.c: (struct write_case_data) Rename `proc_func' member to `case_func' and update all references. (procedure) Rewrite as one-line wrapper around internal_procedure(). (struct multipass_aux_data) New. (multipass_callback) Renamed multipass_case_func().

Tue May 2 15:43:36 2006 Ben Pfaff * variable.c (width_to_bytes): Declarations must precede statements for C90 compliance. Tue May 2 10:42:05 WST 2006 John Darrington * data-out.c, data-in.c, variable.c, variable.h: New functions copy_mangle and copy_demangle for reading/writing cases; emulates the way SPSS deals with strings > 255 bytes. * sys-file-reader.c sys-file-writer.c: Added support for Record 7, subtype 14 needed for strings longer than 255 bytes. * dictionary.c, format.def, value.c : Updated to use MAX_STRING instead of literal values. Also fixed some constness issues. * format.h: Constness * sfm-private.h: Renamed the case_size identifier, since I discovered that SPSS's respect for this variable is very nominal.

(macro PATH_SEPARATOR_STRING) New. Sun Apr 16 16:05:28 2006 Ben Pfaff Continue reforming error message support. In this phase, we get rid of VM() and the other msg() support for "verbosity", replacing it by a new function verbose_msg(). * filename.c: (fn_search_path) Use verbose_msg() instead of msg(VM(), ...). Sat Apr 15 19:53:19 2006 Ben Pfaff * sfm-private.h: Get rid of #defines after #error, which makes no sense. Sat Apr 15 19:48:57 2006 Ben Pfaff Get rid of our own int32 type in favor of the standard int32_t type. * sfm-private.h: (int32 macro) Don't define this anymore. Do include . * sys-file-reader.c: Use int32_t instead of int32 throughout. * sys-file-writer.c: Use int32_t instead of int32 throughout. Sat Apr 15 19:36:47 2006 Ben Pfaff Remove ill-considered file routines that are no longer used. * filename.c: (fn_open_ext) Removed. (fn_close_ext) Removed. * filename.h: (struct file_ext) Removed. Mon Apr 3 13:22:39 2006 Ben Pfaff * variable.c (var_is_valid_name): Move declarations before code for C90 compliance. Tue Apr 4 15:28:40 WST 2006 John Darrington * filename.ch (fn_interp_vars): Fixed small buglet. Tue Mar 28 13:47:16 WST 2006 John Darrington * filename.[ch] (fn_interp_vars): Changed the signature and semantics so as to modify the string inline. Thus makeing it easier to destroy the results when no longer needed. 2006-03-25 Jason Stover * category.c (cat_stored_values_destroy): Fixed memory leak. Fri Mar 24 18:15:41 2006 Ben Pfaff Add some missing frees. Thanks to John Darrington for reporting these. * any-writer.c (any_writer_close): Free writer. * any-reader.c (any_reader_close): Free reader. Mon Mar 20 16:33:53 2006 Ben Pfaff * por-file-reader.c: (error) Mark as NO_RETURN. Sat Mar 11 15:06:07 WST 2006 John Darrington * settings.c: Changed default value of scompress to true. Sat Mar 4 13:22:51 2006 Ben Pfaff * sfm-private.h: Include variable.h, to get SHORT_NAME_LEN. * value.h: Remove check on MAX_SHORT_STRING, which I don't think really applies. * variable.h: Move definition of SHORT_NAME_LEN, LONG_NAME_LEN here from pref.h.orig. Sat Mar 4 12:50:48 WST 2006 John Darrington * sys-file-reader.c: Fixed bug reading compressed files. Thu Mar 2 08:40:33 WST 2006 John Darrington * Numerous renames. See src/ChangeLog for details. * Moved files from src directory
