[jira] Created: (HARMONY-1978) [drlvm][testing] gc.Free fails for
me on SUSE9
[drlvm][testing] gc.Free fails for me on SUSE9
----------------------------------------------
Key: HARMONY-1978
URL: http://issues.apache.org/jira/browse/HARMONY-1978
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: ia32 SUSE9
Reporter: Evgueni Brevnov
Attachments: gc.Free.patch
gc.Free started to fail with the following log:
FAILED, Amount of free memory increases
FAILED, Amount of free memory increases
PASSED
With the help of Salikh and Ivan it was identified that the test is NOT QUITE CORRECT.
The behavior depends on initial memory reserved by GC for java heap.
The fix is in attach. Please review.
Thanks
Evgueni

Evgueni Brevnov commented on HARMONY-1978:
------------------------------------------
I'm OK with the Salikh's patch assumig it is acceptable to have somke tests which depends on configuration/implementation. In particular, initial heap size (-Xms) and GC implementation may affect test runs. What worries me a little is that test will fail in case of increase of free memory space. Salikh you said: "..(there is nothing wrong with free space increasing in the face of heap resize). "
Thanks

[jira] Updated: (HARMONY-1978) [drlvm][testing] gc.Free fails for
me on SUSE9
Posted by "Salikh Zakirov (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-1978?page=all ]
Salikh Zakirov updated HARMONY-1978:
------------------------------------
Attachment: gc.Free.1.patch
-1 to gc.Free.patch. Reasons:
(1) gc.Free.patch does not address any of the problems desribed above,
i.e. warning will still be printed together with PASSED message, and the warning message
is incorrect (there is nothing wrong with free space increasing in the face of heap resize).
(2) it makes test almost useless. Initially, test checked sanity of the value returned by Runtime.freeMemory(),
after the modification it checks only trivial object allocation.
I suggest another patch to fix the issue: gc.Free.1.patch.
It contains 2 modifications to address issues:
1) in case of FAILED message terminate the test
2) do not attempt to allocate more than 1/2 of the space reported as free. Limit is set to free/4 as the allocation
is perfomed as geometry progression: 1+2+4+...
It still has an implementation assumption that GC will not resize the heap as long as less than 1/2 of the
heap is free, which I consider reasonable (and passing on both DRLVM and RI)

This test gc.Free doesn't fail for me on SUSE9 and on other linuxes not to mention windows. What is it I am missing?
