Nim Lhûg commented on VFS-617: ------------------------------ This is breaking chrooted SFTP on my end as well. What's the status of this? Is anyone working on this? > isReadable fails if unable to determine group identity > ------------------------------------------------------ > > Key: VFS-617 > URL: https://issues.apache.org/jira/browse/VFS-617 > Project: Commons VFS > Issue Type: Bug > Affects Versions: 2.1 > Environment: Windows 7 Java 7. Failure occured connecting via SFTP to > a Synology box running DSM 6. > Reporter: Tim Nickels > > The doIsReadable method of SftpFileObject throws an exception if the system > cannot identify group/owner permissions....... > Exception in thread "main" org.apache.commons.vfs2.FileSystemException: Could > not determine if file "sftp://myURI" is readable. > at > org.apache.commons.vfs2.provider.AbstractFileObject.isReadable(AbstractFileObject.java:1761) > at com.avenca.vfs.VFSUtils.main(VFSUtils.java:41) > Caused by: com.jcraft.jsch.JSchException: Could not get the groups id of the > current user (error code: 1) > at > org.apache.commons.vfs2.provider.sftp.SftpFileSystem.getGroupsIds(SftpFileSystem.java:263) > at > org.apache.commons.vfs2.provider.sftp.SftpFileObject.getPermissions(SftpFileObject.java:317) > at > org.apache.commons.vfs2.provider.sftp.SftpFileObject.doIsReadable(SftpFileObject.java:335) > at > org.apache.commons.vfs2.provider.AbstractFileObject.isReadable(AbstractFileObject.java:1757) > The problem is the method is using > return getPermissions(true).isReadable() > The folder *is* readable without these permissions, and so should be set to > return getPermissions(false).isReadable() > Which correctly allows the system to identify a readable folder without > adding unnecessary restrictions. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
