+2003-06-24 Benjamin Kosnik <bkoz@redhat.com>
+ Ulrich Drepper <drepper@redhat.com>
+
+ * testsuite/testsuite_performance.h: Tweak mallinfo.
+
+2003-06-24 Paolo Carlini <pcarlini@unitus.it>
+ Nathan C. Myers <ncm-nospam@cantrip.org>
+
+ * include/std/std_fstream.h (_M_filepos): Remove.
+ (_M_reading, _M_writing): New, encode the various I/O modes:
+ 'read', 'write' and 'uncommitted'.
+ (sync): If there is something to flush, do it, then go to
+ 'uncommitted' mode.
+ * include/bits/fstream.tcc (_M_set_buffer): Overhaul to deal
+ with three different cases: __off > 0 (upon underflow),
+ __off == 0 (upon overflow), __off == -1 (upon open, setbuf,
+ seekoff/pos).
+ (_M_underflow): Don't call overflow, set _M_reading to true
+ on success, tweak.
+ (pbackfail): Set _M_reading to true on pback creation, tweak.
+ (overflow): Don't seek, deal with overflow in 'uncommitted' mode,
+ set _M_writing to true on success, tweak.
+ (seekoff): Simplify, set _M_reading, _M_writing to false, call
+ _M_set_buffer(-1) ('uncommitted').
+ (open, close, setbuf): Set _M_reading, _M_writing to false and
+ call _M_set_buffer(-1), tweak.
+ (basic_filebuf): Don't set _M_buf_unified.
+ (_M_destroy_internal_buffer): Don't call setg and setp.
+ * include/ext/stdio_filebuf.h (stdio_filebuf): Use _M_reading,
+ _M_writing and _M_set_buffer(-1).
+ * include/std/std_streambuf.h (_M_move_out_cur, _M_move_in_cur,
+ _M_out_lim, _M_buf_unified): Remove.
+ (basic_streambuf): Don't set _M_out_lim and _M_buf_unified.
+ (setp): Don't set _M_out_lim.
+ * testsuite/27_io/basic_filebuf/sbumpc/char/1-io.cc: Fix for
+ the new logic ('read', 'write' and 'uncommitted' modes): e.g.,
+ upon open the mode is 'uncommitted' and therefore the put area
+ pointers are null.
