Hello everybody,
I have a problem with lstat64() reporting a wrong (?) ctime.
Please take a look at this strace snippet:
06:44:45.003059 open("/dev/null", O_RDONLY) = 4
06:44:45.003094 open("./4/8/10.txt.up.tmp",
O_WRONLY|O_CREAT|O_TRUNC, 0600) = 5
06:44:45.003145 open("/tmp/ram/fsvs-test-1000/tmp-repos-path/db/revs/4",
O_RDONLY) = 6
06:44:45.003187 lseek(6, 2630937, SEEK_SET) = 2630937
06:44:45.003217 read(6, "id: 13j.0.r4/2630937\ntype: file\n"...,
4096) = 4096
06:44:45.003273 close(6) = 0
06:44:45.003316 open("/tmp/ram/fsvs-test-1000/tmp-repos-path/db/revs/4",
O_RDONLY) = 6
06:44:45.003357 lseek(6, 40515, SEEK_SET) = 40515
06:44:45.003386 read(6, "DELTA\nSVN\0\0\0\7\1\7\2074-8-10\nENDREP\nDE"...,
4096) = 4096
06:44:45.003435 write(5, "4-8-10\n", 7) = 7
06:44:45.003481 open("/tmp/ram/fsvs-test-1000/tmp-repos-path/db/revs/4",
O_RDONLY) = 7
06:44:45.003524 lseek(7, 2630937, SEEK_SET) = 2630937
06:44:45.003554 read(7, "id: 13j.0.r4/2630937\ntype: file\n"...,
4096) = 4096
06:44:45.003610 close(7) = 0
06:44:45.003650 close(5) = 0
06:44:45.003679 close(4) = 0
06:44:45.003707 chown32("./4/8/10.txt.up.tmp", 1000, 1000) = 0
06:44:45.003741 chmod("./4/8/10.txt.up.tmp", 0644) = 0
06:44:45.003778 utimes("./4/8/10.txt.up.tmp",
{1150863412, 890049}) = 0
06:44:45.003813 lstat64("./4/8/10.txt.up.tmp",
{st_dev=makedev(0, 14), st_ino=4139057, st_mode=S_IFREG|0644,
st_nlink=1, st_uid=1000, st_gid=1000, st_blksize=4096,
st_blocks=8, st_size=7, st_atime=2006/06/21-06:16:52,
st_mtime=2006/06/21-06:16:52,
st_ctime=2006/06/21-06:44:44}) = 0 <<<=======HERE
06:44:45.003896 rename("./4/8/10.txt.up.tmp", "./4/8/10.txt") = 0
06:44:45.003935 close(6) = 0
If you take a look at the marked line, you see that the reported ctime is a
second lower than expected.
An "ls -lac --full-time" of this file shows the expected value
06:44:45.003875.
This is on 2.6.16.14, compiled with debian gcc 4.1.2 20060604 prerelease, on
an Pentium M 1.73GHz; the filesystem is tmpfs.
Is that the correct behaviour, or a known failure of the kernel?
How can I work around that?
Thank you for your help!
Regards,
Phil
