+
+ 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(),

+ 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

+ functions.
+
+Wed Apr 26 12:58:46 2006 Ben Pfaff <blp@gnu.org>
+
+ Improve the way we handle the various parsing "states". Until now
+ we've hard-coded the state transitions in the command definition
+ file, but that's error-prone and, worse, it's redundant--we can
+ figure out what state we're in anyhow. We can cleanly handle
+ INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
+
+ * procedure.c (case_source_is_complex): Removed.
+ (discard_variables) No need to set pgm_state anymore.
+
+Tue Apr 25 11:06:49 2006 Ben Pfaff <blp@gnu.org>

+ message.c into libpspp.
+
+ * message.c: Move to libpspp.
+
+Tue Apr 25 10:47:37 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming error message support. In this phase, drop
+ actual message printing from core code, substituting a callback,
+ and add the callback to each UI. Also, move verbose_msg() into
+ its own module.
+
+ * message.c: (var err_error_count) Renamed error_count and moved
+ to ui/terminal/msg-ui.c.
+ (var err_warning_count) Renamed warning_count and moved to
+ ui/terminal/msg-ui.c.
+ (err_check_count) Renamed check_msg_count() and moved to
+ ui/terminal/msg-ui.c.
+ (dump_message) Rewrote to take stream instead of function pointer
+ and moved to ui/terminal/msg-ui.c.
+ (msg_emit) Moved its guts to ui/terminal/msg-ui.c as handle_msg()
+ and rewrote to just pass message to callback.
+
+ (var err_verbosity) Renamed "verbosity" and moved to

+
+Mon Apr 24 17:40:08 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming error message support. In this phase, rename
+ all the message functions and types to start with "msg", except
+ for the ones that will be moving to other modules anyway.
+
+ All references to the identifiers below were updated likewise.
+
+ * message.c: (err_done) Renamed msg_done().
+ (err_push_file_locator) Renamed msg_push_msg_locator().
+ (err_pop_file_locator) Renamed msg_pop_msg_locator().
+ (err_location) Renamed msg_location().
+ (err_set_command_name) Renamed msg_set_command_name().
+
+Mon Apr 24 14:11:33 2006 Ben Pfaff <blp@gnu.org>
+
+ * message.c: Use exit.h from gnulib instead of checking for and
+ defining EXIT_SUCCESS and EXIT_FAILURE by hand.
+
+Sun Apr 23 22:00:23 2006 Ben Pfaff <blp@gnu.org>
+
+ 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.
+
+ * message.c: (tmsg) Removed.
+ (msg) Use err_msg() instead of err_vmsg(). Format message
+ ourselves.
+ (err_vmsg) Renamed err_msg(). Changed interface, dropping message
+ and va_list args which are now in the error struct.
+
+Sun Apr 23 20:35:28 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming error message support.
+
+ * message.c: Use linebreak module from gnulib instead of home-brew
+ line breaking.
+ (puts_stdout) Rewrote.
+ (dump_message) Rewrote. Changed interface and updated all callers.
+ (compulsory_break) Removed.
+ (char_is_break) Removed.
+ (break_before) Removed.
+ (break_after) Removed.
+ (macro BREAK_LONG_WORD) Removed.
+
+Sun Apr 16 20:41:10 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming error message support. In this phase, we
+ divide the classification of messages along "category" and
+ "severity" axes.
+
+ * message.c: (err_vmsg) Rewrite to deal with categories and
+ severities in a straightforward manner instead of mixing them into
+ classes.
+ [0] (puts_stderr) Removed (dead code).
+ (msg) Changed first argument from `int' to `enum msg_class'.
+ (tmsg) Ditto.
+
+Sun Apr 16 18:53:12 2006 Ben Pfaff <blp@gnu.org>
+
+ GNU standards require "file name" instead of "filename" in
+ documentation. It's nice for our code to follow the convention
+ too.
+
+ Basically did search and replace in the whole source tree. Major
+ changes in function names or struct member names have their own
+ change log entries.
+
+Sun Apr 16 15:58:56 2006 Ben Pfaff <blp@gnu.org>
+
+ 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().
+
+ * message.c: (verbose_msg) New function.
+ (err_vmsg) Remove support for verbosity levels.
+
+Sun Apr 16 11:46:51 2006 Ben Pfaff <blp@gnu.org>
+
+ Start reforming error message support. In this phase, we get rid
+ of "installation errors" and change all uses of msg() in the
+ output drivers to uses of error() or error_at_line().
+
+ * message.c: (err_vmsg) Get rid of IE, IS support.
+
+Sat Mar 11 14:17:47 WST 2006 John Darrington <john@darrington.wattle.id.au>
+
+ * automake.mk: Changed the pattern specific AM_CPPFLAGS to two target
+ specific ones. Eventually there will be none at all.
+
+ * automake.mk: Moved the pspp binary to ui/terminal
+
+Sat Mar 4 12:59:08 2006 Ben Pfaff <blp@gnu.org>
+
+ * In many source files, #include "compiler.h" to get GCC attribute
+ definitions.
+
+Sat Mar 4 12:28:09 2006 Ben Pfaff <blp@gnu.org>
+
+ * In many source files, replace INT_DIGITS by
+ INT_STRLEN_BOUND(int) and include intprops.h.

+
+ Try to reduce some of the nastier dependencies on the error
+ module, and at the same time make PSPP nicer to deal with, by
+ getting rid of fatal errors. All the existing calls to msg (FE,
+ ...) or err_cond_fail() or err_failure() have been replaced by
+ propagating an error upward to the command-dispatch layer.
+ Unfortunately this propagation took a fair bit of extra mechanism,
+ because now a lot of functions can fail that couldn't before.
+
+ New command return value CMD_CASCADING_FAILURE which indicates to
+ the command processor that syntax file processing should be
+ abandoned. Many commands were modified to return
+ CMD_CASCADING_FAILURE. When this modification was trivial it
+ isn't mentioned in detail below.
+
+ Transformation procedures (trns_proc_func) and free functions
+ (trns_free_func) now have a `bool' return type, which is normally
+ true, but false when an I/O or other serious error occurs. All
+ transformation functions were modified to have this return type.
+ When this modification was trivial it isn't mentioned in detail
+ below.
+
+ * pspp-error.h: (FE) Removed this error class.
+
+ * error.c: (err_failure) Removed.
+ (err_cond_fail) Removed.
+ (err_break) Removed (it was unused).
+ (err_check_count) Don't cause a fatal error--instead, stop reading
+ the syntax file.
+ (err_vmsg) Don't have FE anymore, so no need to call terminate().
+
+ * any-reader.c: (any_reader_error) New function.
+
+ * any-writer.c: (any_writer_write) Propagate
+ scratch_writer_write_case()'s new return value.
+ (any_writer_error) New function.
+ (any_writer_close) Propagate underlying function's new return
+ value.
+
+ * casefile.c: Add an "error state" to a casefile. A casefile that
+ encounters an I/O error enters the error state, and afterward
+ reading and writing cases fails.
+ (struct casefile) Add `ok' member.

+
+ Add scratch file handles.
+
+ Now a file handle can refer to a disk file, to an in-memory
+ structure, or to the "inline" file, instead of just to a disk
+ file. The introduction of new categories means that special cases
+ for the inline file in a few places could be eliminated, but it
+ also means that code that assumed that a handle refers to a file
+ has to check for that.
+
+ Also, now file handles can be freed, so code now must be sure not
+ to access a handle after closing it (with fh_close()).
+
+ * Makefile.am: Add any-reader.c, any-reader.h, any-writer.c,
