* src/imfs/imfs_config.c: New file containing IMFS configuration
	information split from libc/base_fs.c.
	* src/imfs/ioman.c: New file. Moved from lib/libc. Missed previously.
	* src/imfs/Makefile.am: Added imfs_config.c and ioman.c.

* Makefile.am, configure.in:  Introduce GNU canonicalization to libfs/.
	The approach is currently a bit of a hack as GNU canonicalization
	does not support the per-BSP build some of the other directories
	require.  As more of the tree is converted, this will become less
	of an issue.

068b64735c Patch from Chris Johns <cjohns@cybertec.com.au> so the directory 
read function in the IMFS properly returns the inode number.

e5d6705e46 Patch from Chris Johns <cjohns@cybertec.com.au> to add support for 
stat()'ing a symbolic link.  This is needed to support the port
of the BSD commands like ls to RTEMS.
 2000-06-30 12:33:13 +00:00
Joel Sherrill
e42a135973 Patch from Chris Johns <cjohns@cybertec.com.au> and 
Jennifer Averett <jennifer.averett@oarcorp.com> to fix
appends (O_APPEND at open time) on in-memory files.

A call such as:

    fd = open (file, O_APPEND | O_WRONLY);

did not append to the end of the file.

94b357c2b3 Unmount was failing as a side-effect of splitting the rmnod handler 
and not handling every case properly.

b568ccb745 The object memfile.o was being included in the miniIMFS even though it 
should not have been.  This required that IMFS_rmnod be split into
three separate (per file type) routines to avoid dependencies.
In the end, a miniIMFS application is 6K smaller than one using the
full IMFS.

79991746da New files created by split of old imfs_handlers.c. 1999-10-26 21:51:20 +00:00
Joel Sherrill
657e1bf66b Added initial cut at miniIMFS which leaves out memfile and directory 
readdir support.  The next step is to add a mount table and configure
either the miniIMFS or the full IMFS at the application level.

51435fc7c5 Split null handlers table to own file and renamed. 
Renamed IMFS handler tables to include IMFS prefix.

dd0f32614c Added rtems_filesystem_freenode() macro and added calls at appropriate 
places to make sure memory allocated for filesystem specifif nodes
gets freed.

b10f6e12e0 Corrected bug where pointer to doubly linked blocks was being incorrectly 
calculated.
 1999-03-08 21:39:39 +00:00
Joel Sherrill
3cf8394af5 Changed IMFS to use IMFS_NAME_MAX as the maximum length of a basename 
rather then NAME_MAX.  NAME_MAX is 255 and that lets IMFS chew up memory
too fast.  Perhaps in the future, the places in IMFS that put a maximum
length name string on the stack and the jnode structure does not include
a maximu length name string can be fixed so this is not a problem.

efb1b830bb Corrected multiple places the file size was not being properly updated. 1999-02-10 17:04:54 +00:00

2f87c84349 Corrected spacing and added some new error checks that were needed 
to avoid dereferencing NULLs.

a4e2f08c25 Added imfs_fdatasync routine that gets called from both fdatasync and datasync. 1998-12-03 22:19:06 +00:00

7a3878b26f Modifications for RTEMS_UNIX. 1998-12-03 22:17:13 +00:00
Joel Sherrill
07a3253de2 Added base version of file system infrastructure. This includes a major 
overhaul of the RTEMS system call interface.  This base file system is
the "In-Memory File System" aka IMFS.

The design and implementation was done by the following people:

  + Joel Sherrill (joel@OARcorp.com)
  + Jennifer Averett (jennifer@OARcorp.com)
  + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com)
  + Kerwin Wade (wade@OARcorp.com)

PROBLEMS
========
  + It is VERY likely that merging this will break the UNIX port.  This
    can/will be fixed.

  + There is likely some reentrancy/mutual exclusion needed.

  + Eventually, there should be a "mini-IMFS" description table to
    eliminate links, symlinks, etc to save memory.  All you need to
    have "classic RTEMS" functionality is technically directories
    and device IO.  All the rest could be left out to save memory.
