* NAME
|
|
* rename01
|
|
*
|
|
* DESCRIPTION
|
|
* This test will verify the rename(2) syscall basic functionality.
|
|
* Verify rename() works when the "new" file or directory does not exist.
|
|
*
|
|
* ALGORITHM
|
|
* Setup:
|
|
* Setup signal handling.
|
|
* Create temporary directory.
|
|
* Pause for SIGUSR1 if option specified.
|
|
*
|
|
* Test:
|
|
* Loop if the proper options are given.
|
|
* 1. "old" is plain file, new does not exists
|
|
* create the "old" file, make sure the "new" file
|
|
* dose not exist
|
|
* rename the "old" to the "new" file
|
|
* verify the "new" file points to the "old" file
|
|
* verify the "old" file does not exist
|
|
*
|
|
* 2. "old" is a directory,"new" does not exists
|
|
* create the "old" directory, make sure "new"
|
|
* dose not exist
|
|
* rename the "old" to the "new"
|
|
* verify the "new" points to the "old"
|
|
* verify the "old" does not exist
|
|
* Cleanup:
|
|
* Print errno log and/or timing stats if options given
|
|
* Delete the temporary directory created.
|
|
*
|
|
* USAGE
|
|
* rename01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -f : Turn off functionality Testing.
|
|
* -i n : Execute test n times.
|
|
* -I x : Execute test for x seconds.
|
|
* -P x : Pause for x seconds between iterations.
|
|
* -t : Turn on syscall timing.
|
