* libio/fileops.c (_IO_file_sync_mmap): New function.
(_IO_file_jumps_mmap): Use it.
(_IO_file_underflow_mmap): Rewritten. If after EOF or fflush,
repeat the stat check and resize the mapped buffer as necessary.
2002-07-31 Roland McGrath <roland@frob.com>
* libio/fileops.c (decide_maybe_mmap): New static function.
Code taken from libio/iofopen.c:__fopen_maybe_mmap to try to
mmap the file contents. Then switch the jump tables to the mmap
tables if it worked, or the vanilla file tables if not.
(_IO_file_underflow_maybe_mmap): New function.
(_IO_file_seekoff_maybe_mmap): New function.
(_IO_file_xsgetn_maybe_mmap): New function.
(_IO_file_jumps_maybe_mmap): New variable, jump table using those.
* libio/libioP.h: Declare those.
* libio/wfileops.c (_IO_wfile_underflow_maybe_mmap): New function.
(_IO_wfile_jumps_maybe_mmap): New variable, jump table using that.
* libio/iofopen.c (__fopen_maybe_mmap): Don't try to mmap here.
If the stream is read-only, set its jump tables to those new ones.
* libio/iofdopen.c (_IO_new_fdopen) [_G_HAVE_MMAP]: Set the initial
jump tables to the maybe_mmap ones, and don't call __fopen_maybe_mmap.
We need the tables set before _IO_file_attach.
* libio/tst-mmap-eofsync.c: New file.
* libio/tst-mmap-fflushsync.c: New file.
* libio/bug-mmap-fflush.c: New file.
* libio/tst-mmap2-eofsync.c: New file.
* libio/Makefile (tests): Add them.
* libio/wfileops.c (_IO_wfile_underflow_mmap): Don't set EOF bit when
_IO_file_underflow_mmap fails, it already set the appropriate bit.
