Nathan C. 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. * testsuite/27_io/basic_filebuf/sbumpc/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/seekoff/char/3-io.cc: Ditto. * testsuite/27_io/basic_filebuf/seekpos/char/3-io.cc: Ditto. * testsuite/27_io/basic_filebuf/setbuf/char/1.cc: Ditto. * testsuite/27_io/basic_filebuf/sgetc/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/sgetc/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/sgetn/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/sgetn/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/snextc/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/snextc/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/sputbackc/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/sputbackc/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/sputc/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/sputc/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/sputc/char/9701-2.cc: Ditto. * testsuite/27_io/basic_filebuf/sputn/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/sputn/char/1-out.cc: Ditto. * testsuite/27_io/basic_filebuf/sputn/char/9701-1.cc: Ditto. * testsuite/27_io/basic_filebuf/sungetc/char/1-io.cc: Ditto. * testsuite/27_io/basic_filebuf/sungetc/char/1-out.cc: Ditto. * include/bits/fstream.tcc (showmanyc): Use only the documented derivation interface to basic_streambuf (gptr(), setg(), etc.) to work right with user specializations. * include/bits/streambuf.tcc (sbumpc, sputbackc, sungetc, sputc, xsgetn, xsputn, __copy_streambufs): Likewise. * include/std/std_streambuf.h (in_avail, sgetc, uflow, stossc): Likewise. * include/std/std_fstream.h (_M_create_pback, _M_destroy_pback, xsgetn): Likewise.
