* libcgroup: Fix test cases to use new APIs.Dhaval Giani2008-08-131-2/+9
| | | | | | | | | | | | The APIs changed and we could no longer smoke test the library. Updating it now.

* libcgroup: fix wrong malloc size in testcaseDhaval Giani2008-07-041-1/+1
| | | | | | | | | | | | | | | From: Sudhir Kumar <skumar@linux.vnet.ibm.com> This patch fixes a small mistake in the previous patch for malloc size. Of course the size should not be of the pointer but the structure.

* libcgroup: Fix test cases to use CPU controller if availableDhaval Giani2008-07-021-2/+10
| | | | | | | | | | | | | The test cases used the memory controller. This is not a good idea since most distro kernels don't enable it by default. For the moment I'm setting it to use CPU if memory is not found, but in the longer term I am planning to set it to use CPU first and then memory.

| | | | | | | | | | | 0 is a valid PID for cgroup filesystem. It moves the current task into the cgroup. Let's try -1 instead. Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> git-svn-id: https://libcg.svn.sourceforge.net/svnroot/libcg/trunk@96 4f4bb910-9a46-0410-90c8-c897d4f1cd53

| | | | | | | | | | | | | | libcgroup: adds sanity check in libcgroup testcases binary This patch adds a sanity check on cgroup file system info in testcases. If cgroup filesystem is not mounted and script sends the info as mounted, then the binar would have failed. This patch handles that.

| | | | | | | | | | | | | | | | | | libcgroup: testcases for cgroup_modify_cgroup() This patch adds testcases for libcgroup API cgroup_modify_cgroup() testing. The API is called with filesystem mounted (FS_MOUNTED=1) and return values are checked. The API is first called with the same cgroup(the one which is existing in the file system, and with all the same parameters). The second time it is called with a null cgroup. Third time it is called with a new cgroup having different controller. The filesystem is checked if the values have been modified.

| | | | | | | | | | | | | | | | libcgroup: further testcases for create_cgroup() and delete_cgroup() This patch adds testcases for libcgroup API cgroup_create_cgroup() and cgroup_delete_cgroup() testing.

| | | | | | | | | | | | | | | | | | | | | libcgroup: libcgroup testcases for cgroup_attach_task() This patch adds 3 testcases for libcgroup API cgroup_attach_task() testing. The API is called under the same but two conditions(FS_MOUNTED=0/1) and return values are checked. For FS_MOUNTED=1 the API is first called without intializing ie without calling cgroup_init(), and then after cg_init(). Each time the null cgroup is passed. The task is checked if it exists under the root group's tasks file. The 4th testcase calls cgroup_attach_task_pid() with an invalid pid. Testcases for FS_MOUNTED=2 have to be added.
