2002-08-27 Ulrich Drepper <drepper@redhat.com> * sysdeps/arm/Dist: Add bits/link.h. * sunrpc/Makefile: Distribute thrsvc. * stdio-common/Makefile: Remove more left-overs from old stdio. * include/linewrap.h: Removed. * libio/bug-mmap-fflush.c: Rewrite to not touch source directory. * intl/Makefile (distribute): Add plural-eval.c. * stdio-common/Makefile (headers): Remove bits/stdio_lim.h. This file isn't distributed. Add special rules to install bits/stdio_lim.h. * Make-dist: Remove traces of old stdio. * Makeconfig: Likewise. * locale/Makefile (localedef-aux): New variable. Only md5 assigned to it. These files are not ddistributed in this directory. * sysdeps/unix/sysv/linux/s390/Dist: Add sys/procfs.h. * sysdeps/unix/sysv/linux/s390/s390-64/Dist: Remove sys/procfs.h. * sysdeps/unix/sysv/linux/s390/s390-32/Dist: Likewise. * sysdeps/unix/sysv/linux/Dist: Remove sys/sendfile.h.
2002-08-02* libio/fileops.c (_IO_file_sync_mmap): New function.Roland McGrath
(_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.
