Subject [jira] [Commented] (HADOOP-9227) FileSystemContractBaseTest doesn't test filesystem's mkdir/isDirectory() logic rigorously enough
Date Mon, 25 Mar 2013 13:17:19 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13612603#comment-13612603

>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs
>    Affects Versions: 3.0.0
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Trivial
>             Fix For: 3.0.0
> The {{FileSystemContractBaseTest.mkdirs()}} asserts that a newly created directory is
true, but way of {{FileStatus.isFile()}}, but doesn't assert that the directory is a dir by
way of {{FileStatus.isDir()}}.
> The assertion used is slightly weaker, as the {{isFile()}} test is actually
> {{!isdir && !isSymlink()}}. if an implementation of {{FileSystem.mkdirs()}} created
symlinks then the test would still pass.
> There is one test that looks at the {{isDirectory()}} logic, {{testMkdirsWithUmask()}}
-but as that test is skipped for the s3 filesystems, it is possible for those filesystems
(or similar) to not have their directory creation logic stressed enough.
> The fix would be a trivial single line.
