+ undefined behavior.
+
+Thu Feb 12 23:35:15 2004 Ben Pfaff <blp@gnu.org>
+
+ Add auxiliary argument to procedure() interface. Associated small
+ clean-ups of vfm interface.
+
+ * Updated every caller of procedure() and process_active_file() to
+ reflect modified interface. Simple, ordinary changes not listed
+ otherwise below.
+
+ * Updated every function that implements struct case_stream's
+ `read' function to take a write_case_func and a write_case_data.
+ Also updated every caller of write_case() to instead call them
+ through these arguments. In some cases this meant that the extra
+ args had to be threaded through a couple of extra levels. This
+ wasn't difficult or interesting so the details won't be given.
+
+ * data-list.c: (struct repeating_data_trns) Add members
+ `write_case', `wc_data' as kluge.

+ repeating_data_set_write_case() for all the REPEATING DATA
+ transformations, so that they know where to send their cases.
+ It's a big kluge. Also kluge in END CASE.
+ (end_case_trns_proc) Never called anymore, but we still need it,
+ so just assert(0).
+
+ * sort.c: (read_sort_output) Update to match struct case_stream
+ `read' member.
+
+ * vfm.c: (struct write_case_data) New structure.
+ (proc_func) Removed.

+ (virt_begin_func) Removed.
+ (end_func) Removed.
+ (write_case) Removed.
+ (procedure) Added an auxiliary parameter to each function pointer
+ argument's prototype. Added an auxiliary data parameter.
+ Rewrote.
+ (process_active_file) Ditto.
+ (process_active_file_write_case) Pass aux data along.
+ (close_active_file) Ditto.
+ (procedure_write_case) Ditto.

+
+Thu Feb 12 19:24:53 WST 2004 John Darrington <john@darrington.wattle.id.au>

+ test yet!)
+
+ * Makefile.am: Moved q_sources_c into own variable
+
+Wed Feb 11 23:56:51 2004 Ben Pfaff <blp@gnu.org>
+
+ Miscellaneous cleanups.
+
+ * Change unused to UNUSED in many source files to reflect modified
+ pref.h. Change use of __WIN32__, __MSDOS, __DJGPP__,
+ __CYGWIN32__, __unix__, and unix not to assume that they're
+ defined to a nonzero value. Change use of __attribute__ to use
+ NO_RETURN or PRINTF_FORMAT instead.
+
+ * alloc.h: Move definitions for local_alloc(), local_free() here
+ from ../pref.h.orig and simplify.
+
+ * expr-evl.c: Instead of working differently based on PAGED_STACK,
+ use a pool allocator unconditionally.
+ (CHECK_STRING_SPACE) Removed.
+ (ALLOC_STRING_SPACE) Removed.
+ (expr_evaluate) Use e->pool instead of CHECK_STRING_SPACE and
+ ALLOC_STRING_SPACE.
+
+ * expr-opt.c: (dump_expression) Allocate string pool.
+
+ * expr-prs.c: (expr_free) Free string pool.
+
+ * pool.c: (pool_destroy) This pool must be removed from its
+ parent's list of gizmos, not from its own. Use free_all_gizmos().
+ (pool_clear) New function.
+ (free_all_gizmos) New function.
+ (pool_alloc) Use space in empty block after this one if any.
+ (pool_release) Only empty out blocks, don't actually free() them.

+ dynamically allocating line buffers.
+ (struct print_trns) Always include the `line' member.
+ (internal_cmd_print) Always initialize the `line' member.
+ (alloc_line) Always allocate memory for `line'.
+ (print_trns_proc) Always initialize buf from `line' member.
+ (print_trns_free) Always free `line' memory.
+
+ * sort.c: (allocate_file_handles) Special-case MS-DOS for mkdir()
+ call.
+
