[jira] [Created] (BOOKKEEPER-834) test case error in test class
TestDiskChecker
zhaijia created BOOKKEEPER-834:
----------------------------------
Summary: test case error in test class TestDiskChecker
Key: BOOKKEEPER-834
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-834
Project: Bookkeeper
Issue Type: Bug
Components: bookkeeper-server
Environment: Linux /tmp dir size > 2GB
Reporter: zhaijia
Assignee: zhaijia
Fix For: 4.3.1
In test class TestDiskChecker, test case will fail if tmp dir's usableSpace / totalSpace > 0.95, because threshold will be a negative number.
public void testCheckDiskFull() throws IOException {
File file = File.createTempFile("DiskCheck", "test");
long usableSpace = file.getUsableSpace();
long totalSpace = file.getTotalSpace();
float threshold =
(1f - ((float) usableSpace / (float) totalSpace)) - 0.05f;
< === if "usableSpace / totalSpace" is 0.99, then threshold is -0.04, this is invalid.
diskChecker.setDiskSpaceThreshold(threshold, threshold);
diskChecker.checkDiskFull(file);
}
in my running of test:
