Hi
I think this is a long standing failure.
*** BEGIN OF TEST FSTIME RFS ***
Initializing filesystem RFS
Sleep a few seconds
../../../../../../../rtems/c/src/../../testsuites/fstests/mrfs_fstime/../fstime/test.c:
131 st.st_ctime == st.st_mtime
When I break at end of stat, I see this.
(gdb) p *buf
$1 = {st_dev = 34401048, st_ino = 2, st_mode = 16877, st_nlink = 1,
st_uid = 0, st_gid = 0, st_rdev = 0, st_size = 512, st_atim = {
tv_sec = 567993600, tv_nsec = 0}, st_mtim = {tv_sec = 567993600,
tv_nsec = 0}, st_ctim = {tv_sec = 567993606, tv_nsec = 0},
st_blksize = 512, st_blocks = 1}
Something is happening in test.c with gdb and I can't print the stat buf.
Any ideas? Since this is a generic failure, it would be good to
eliminate it.
It is specific to the RFS as far as I know. The code in the test says ...
/*
* If O_CREAT is set and the file did not previously exist, upon
* successful completion, open() shall mark for update the st_atime,
* st_ctime, and st_mtime fields of the file and the st_ctime and
* st_mtime fields of the parent directory.
*/
Does this apply to the creation of any node in the file system ?
We would have to find the place in the POSIX standard. This statements
like it is
from http://pubs.opengroup.org/onlinepubs/009695399/functions/fopen.html.
This would imply to me that it should but can the FAT filesystem support
this?
No idea.
I removed this test for the FAT file system:
http://git.rtems.org/rtems/commit/?id=bdcf4102f71d1bc2a50f23d2d425d85c24ec0900
Are you hinting that it is generic code which should be in the system
call layer?
No, just wondering where I should look to make the change in the RFS.
The IMFS and JFFS2 pass this test. It is file system specific, see FAT as a
counter example.
