+
+ Continue reforming procedure execution. 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. Pass
+ case to begin_func.
+ (dump_splits) Moved to language/dictionary/split-file.c as
+ output_split_file_values().
+ (struct multipass_split_aux_data) Add "const struct ccase *"
+ parameter to split_func member.
+ (multipass_procedure_with_splits) Add "const struct ccase *"
+ parameter to split_func parameter.
+ (multipass_split_case_func) Save new SPLIT FILE case before
+ outputting case.
+ (multipass_split_output) Pass saved SPLIT FILE case to split_func.

+
+ Continue reforming procedure execution. In this phase, move
+ procedure.c and procedure.h from src to src/data. Update
+ makefiles and #includes accordingly.
+
+ * automake.mk: Remove special rule for src/procedure.o.
+
+ * procedure.c: Moved to src/data.
+
+ * procedure.h: Moved to src/data.

+
+ 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.
+
+ * procedure.c: (global var vfm_source) Make static. Changed
+ external references to use in_input_program(), proc_set_source(),
+ or proc_capture_output() instead.
+ (global var vfm_sink) Make static. Changed external references to
+ use proc_set_sink() instead.
+ (global var default_dict) Move here from data/dictionary.c.
+ (static var permanent_trns_chain) New var.
+ (static var temp_dict) Renamed permanent_dict, updated references.
+ (static var temporary_trns_chain) New var.
+ (static var cur_trns_chain) New var.
+ (static var in_procedure) Removed.
+ (global var t_trns) Removed.
+ (global var n_trns) Removed.
+ (global var m_trns) Removed.
+ (global var f_trns) Removed.
+ (procedure) Even if there's "nothing to do" we need to clear
+ PROCESS IF, N OF CASES, vector state. (This should be
+ abstracted.)
+ (multipass_callback) New function.
+ (multipass_procedure) New function.
+ (open_active_file) Add N OF CASES, FILTER, PROCESS IF
+ transformations. Finalize transformations. No need to call
+ ctl_stack_clear() anymore because finalizers will do that.
+ (write_case) Simplify and rewrite.
+ (execute_transformations) Removed.
+ (filter_case) Removed.
+ (close_active_file) Use proc_cancel_temporary_transformations().
+ No need to clear PROCESS IF, N OF CASES here anymore because
+ helpers do that.
+ (multipass_procedure_with_splits) Keep track of success.
+ (multipass_split_callback) Ditto.
+ (multipass_split_output) Ditto.
+ (discard_variables) No need to call ctl_stack_clear() anymore
+ because finalizers will do that.
+ (proc_capture_transformations) New function.
+ (add_transformation) Rewrite in terms of trns_chain_append().
+ (add_transformation_with_finalizer) New function.
+ (next_transformation) Rewrite in terms of trns_chain_next().
+ (proc_in_temporary_transformations) New function.
+ (proc_start_temporary_transformations) New function.
+ (proc_make_temporary_transformations_permanent) New function.
+ (proc_cancel_temporary_transformations) New function.
+ (cancel_transformations) Rename proc_cancel_all_transformations(),
+ rewrite in terms of trns_chain_destroy().
+ (proc_init) New function.
+ (proc_done) New function.
+ (proc_set_sink) New function.
+ (proc_set_source) New function.
+ (proc_has_source) New function.
+ (proc_capture_output) New function.
+ (add_case_limit_trns) New function.
+ (case_limit_trns_proc) New function.
+ (case_limit_trns_free) New function.
+ (add_filter_trns) New function.
+ (filter_trns_proc) New function.
+ (add_process_if_trns) New function.
+ (process_if_trns_proc) New function.
+ (process_if_trns_free) New function.
+
+Wed Apr 26 20:00:00 2006 Ben Pfaff <blp@gnu.org>
+
+ * procedure.c (create_trns_case): Fix inverted decision on whether
+ numeric values should be initialized to 0 or SYSMIS.
