2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
2012-03-13IMFS: New support functionsSebastian Huber1-1/+1
Add and use IMFS_type() and IMFS_is_directory().
2012-03-13Filesystem: Reference counting for locationsSebastian Huber1-33/+21
o A new data structure rtems_filesystem_global_location_t was introduced to be used for o the mount point location in the mount table entry, o the file system root location in the mount table entry, o the root directory location in the user environment, and o the current directory location in the user environment. During the path evaluation global start locations are obtained to ensure that the current file system instance will be not unmounted in the meantime. o The user environment uses now reference counting and is protected from concurrent access. o The path evaluation process was completely rewritten and simplified. The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation method. Recursive calls in the path evaluation have been replaced with iteration to avoid stack overflows. Only the evaluation of symbolic links is recursive. No dynamic memory allocations and intermediate buffers are used in the high level path evaluation. No global locks are held during the file system instance specific path evaluation process. o Recursive symbolic link evaluation is now limited by RTEMS_FILESYSTEM_SYMLOOP_MAX. Applications can retrieve this value via sysconf(). o The device file system (devFS) uses now no global variables and allocation from the workspace. Node names are allocated from the heap. o The upper layer lseek() performs now some parameter checks. o The upper layer ftruncate() performs now some parameter checks. o unmask() is now restricted to the RWX flags and protected from concurrent access. o The fchmod_h and rmnod_h file system node handlers are now a file system operation. o The unlink_h operation has been removed. All nodes are now destroyed with the rmnod_h operation. o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system operations. o The path evaluation and file system operations are now protected by per file system instance lock and unlock operations. o Fix and test file descriptor duplicate in fcntl(). o New test fstests/fsnofs01.

1999-11-17Updated copyright notice.Joel Sherrill1-2/+1
1998-11-23Added base version of file system infrastructure. This includes a majorJoel Sherrill1-0/+49
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.
