Subject [jira] Commented: (HARMONY-4493) [drlvm][EUT] org.eclipse.jdt.core.tests.model.ClasspathTests.testEncoding cannot remove unicode dir

Ilya Berezhniuk commented on HARMONY-4493:

This bug is reproducible on both 3.2 and 3.3 Eclipse.
Eclipse 3.3 produces another output for this issue, but waits for a long time also.

>             Project: Harmony
>          Issue Type: Bug
>          Components: DRLVM
>         Environment: Linux/ia32
>            Reporter: Ilya Berezhniuk
>            Priority: Minor
> Test org.eclipse.jdt.core.tests.model.ClasspathTests.testEncoding creates directory with
unicode name in its project directory. Then it removes project, it involves removing underlying
files and directories.
> When executing on DRLVM, it cannot remove unicode directory and therefore the whole project,
and then tries 60 times with 1 second delay. So test goes 1 minute, and all remaining tests
in ClasspathTests suite also execute 1 minute.
> Although debugging under Eclipse is now unstable on DRLVM/Linux (it often crashes with
SIGSEGV when using single stepping), I've got some results using breakpoints.
> Looks like the problem is somewhere in enumerating subdirectories of project dir "P".
Eclipse uses org.eclipse.core.internal.localstore.UnifiedTree to enumerate subitems in project
folder: accept(IUnifiedTreeVisitor, int) calls addNodeChildrenToQueue to fill queue with subitems.
But when queue is filled, it contains incorrect path to unicode directory. Directory is named
"src\u3400", but queue item for this directory contains path from 6 to 8 chars and named as
"srcXXXXX", where XXXXX can be various characters including space.
> I cannot determine a cause of this error certainly - so bug is now tagged as [drlvm].
I'll try to go forward and investigate bug deeper.
