Thu Oct 19 22:59:56 WST 2006 John Darrington * procedure.c procedure.h: Encapsulated the static data into a single struct. Sat Oct 14 16:56:44 2006 Ben Pfaff * casefile.c (casereader_read_xfer): Always initialize the case, even on an error condition. Wed Sep 27 09:37:49 WST 2006 John Darrington * procedure.c (case_limit_trns_proc): Fixed buglet which rendered the entire function useless. Mon Sep 25 17:11:46 WST 2006 John Darrington * casefile-private.h casefile.c casefile.h fastfile.c: Created new casereader method casereader_clone. * procedure.c pransformations.h: Introduced new type casenum_t Thu Sep 21 07:00:30 2006 Ben Pfaff * variable.c: (width_to_bytes) Rephrase code for clarify. Sun Jul 16 19:52:03 2006 Ben Pfaff * format.c: (fmt_type_from_string) New function. (fmt_to_string) Include decimals in output if the format has decimals, even if the format type does not. This way, we can accurately reproduce incorrect formats in user output. (check_common_specifier) Make the check for a bad format type an assertion, so we get bug reports if they show up. Fix message. Check for decimal places with a format type that doesn't allow them. (check_input_specifier) Remove check for FMT_X, which has been deleted. (check_output_specifier) Ditto. * format.def: Remove FMT_T, FMT_X, FMT_DESCEND, FMT_NEWREC. * format.h: (macro FMT_TYPE_LEN_MAX) New macro. (struct fmt_desc) Use FMT_TYPE_LEN_MAX in definition.

Wed Jul 12 21:01:00 2006 Ben Pfaff Remove "debugging" code that caused plenty of false positives and no true positives. * case.h (struct ccase): [DEBUGGING] Remove `this' member. * case.c: Remove all references to `this' member. 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. Mon Jun 19 18:05:42 WST 2006 John Darrington * casefile.c (casefile_get_random_reader): Nasty hack to get around the mode assertion. * format.c: Removed tortological assertion. Fri Jun 9 12:20:09 2006 Ben Pfaff Reform string library. * file-name.c (fn_interp_vars): Change interface to take a substring as input. Updated all users. Fri Jun 9 12:11:24 2006 Ben Pfaff * format.c (measure_is_valid): Really return false when m >= n_MEASURES.

Sat May 6 22:48:30 2006 Ben Pfaff * storage-stream.c (storage_source_decapsulate): Destroy case source to fix memory leak. Sat May 6 22:46:47 2006 Ben Pfaff * scratch-reader.c (scratch_reader_read_case): Copy into existing case passed as argument instead of initializing the argument as a case. Fixes memory leak that showed up in tests/command/aggregate.sh with scratch files. Sat May 6 22:45:55 2006 Ben Pfaff * procedure.c (proc_done): Destroy default_dict, to fix memory leak. Sat May 6 22:44:44 2006 Ben Pfaff Simplify procedure_with_splits(). * procedure.c (struct split_aux_data): Removed case_count member. (procedure_with_splits) Don't initialize case_count. (split_procedure_case_func) Check whether prev_case is null instead of case_count. (split_procedure_end_func) Ditto.

(does_dict_need_translation) Removed. Sat May 6 15:35:42 2006 Ben Pfaff Make dictionary compacting functions a little more general. * dictionary.c (dict_needs_compaction): Rename dict_compacting_would_shrink(). Update all callers. (dict_compacting_would_change) New function. Sat May 6 14:25:49 2006 Ben Pfaff * sys-file-writer.c: (does_dict_need_translation) Fix bug: inverted return value (!). Sat May 6 13:37:52 2006 Ben Pfaff Continue reforming procedure execution. * procedure.c: Search and replace "vfm" by "proc". Notably: (static var vfm_source) Rename proc_source. Update all references. (static var vfm_sink) Rename proc_sink. Update all references. Sat May 6 12:38:55 2006 Ben Pfaff Continue reforming procedure execution. In this phase, remove PROCESS IF, which was deprecated anyway and can be easily simulated with TEMPORARY followed by SELECT IF. * procedure.c: (open_active_file) Don't call add_process_if_trns(). (discard_variables) Get rid of redundant call to proc_cancel_all_transformations(). (add_process_if_trns) Removed. (process_if_trns_proc) Removed. (process_if_trns_free) Removed.

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. (procedure_with_splits) Add "const struct ccase *" parameter to begin_func parameter. Make ccase parameter const in proc_func parameter. (split_procedure_case_func) Don't dump split file group.

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(). Use struct multipass_aux_data as auxiliary data. (multipass_end_func) New function.

Update makefiles and #includes accordingly. * procedure.c: Moved here from src/. * procedure.h: Moved here from src/. Wed May 3 22:42:12 2006 Ben Pfaff Continue reforming procedure execution. In this phase, get rid of many global variables, consolidating procedure execution in procedure.c. Encapsulate transformations in new "struct trns_chain". Also, change implementation of N OF CASES, FILTER, and PROCESS IF from special cases to transformations. * automake.mk: (src_data_libdata_a_SOURCES) Add transformations.c, transformations.h. * dictionary.c: (global variable default_dict) Move to src/procedure.c. * variable.h: (TRNS_*) Move to transformations.h. (struct transformation) Move to transformations.c. Thu May 4 13:47:06 WST 2006 John Darrington * sys-file-reader.c: Fixed invalid read problems. Tue May 2 15:57:10 2006 Ben Pfaff * storage-stream.c: Add missing function comments. Tue May 2 15:50:21 2006 Ben Pfaff Continue reforming procedure execution. In this phase, add some new, needed functionality to storage-stream. * storage-stream.c: (storage_source_decapsulate) New function. 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. Mon May 1 15:45:42 2006 Ben Pfaff Change case limit type from int to size_t. * dictionary.c: (struct dictionary) Change type of case_limit member. (dict_get_case_limit) Change return type.

Wed Apr 26 14:55:19 2006 Ben Pfaff * variable.h: (struct variable) Remove `init' member and all references to it from other files. It was initialized in several places, but nothing really ever used it for anything worthwhile. Thanks to Jason Stover for pointing out how confusing this member is. Sun Apr 23 22:04:45 2006 Ben Pfaff Continue reforming error message support. In this phase, get rid of message "titles" and put the message text in `struct error'. Now `struct error' encapsulates a message more properly. * casefile.c: (io_error) Use err_msg() instead of err_vmsg(). Format message ourselves. * data-in.c: (vdls_error) Ditto. * por-file-reader.c: (error) Ditto. * sys-file-reader.c: (corrupt_msg) Ditto. Sun Apr 16 18:49:51 2006 Ben Pfaff GNU standards require "file name" instead of "filename" in documentation. It's nice for our code to follow the convention too. * casefile.c: (struct casefile) Rename `filename' member to `file_name'. Updated all references. * file-name.c: [!unix] (struct file_identity) Rename normalized_filename member to normalized_file_name. Updated all references. Sun Apr 16 18:35:33 2006 Ben Pfaff We don't really support anything but Unix-like environments well, so we might as well de-obfuscate by writing directory and path separators explicitly. * file-name.h: (macro DIR_SEPARATOR) Removed. Changed all usages to just '/'. (macro PATH_SEPARATOR) Removed. Changed all usages to just ':'. (macro DIR_SEPARATOR_STRING) Removed. Changed all usages to just "/". (macro PATH_SEPARATOR_STRING) Removed. Changed all usages to just ":" Sun Apr 16 18:28:35 2006 Ben Pfaff GNU standards require "file name" instead of "filename" in documentation.

(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.
