Logan created SSHD-1130: --------------------------- Summary: Sftp directory listing with permission denied error Key: SSHD-1130 URL: https://issues.apache.org/jira/browse/SSHD-1130 Project: MINA SSHD Issue Type: Improvement Affects Versions: 2.1.0, 2.6.0 Reporter: Logan
Iterating a directory with no valid permission using DirectoryStream throws SftpException wrapped as RuntimeException on the iterator.next(), While this is perfectly valid with Iterator interface standard, to really determine if the issue is with permissions we have look at the cause of RuntimeException. {code:java} try (DirectoryStream<Path> ds = Files.newDirectoryStream(remoteDir)) { for (Path remoteFile : ds) { ..} } catch (RuntimeException ex) { Throwable cause = ex.getCause(); if (cause != null && cause instanceof SftpException) { System.err.println("sftp error..probably permissions issue: " + ex.getMessage()); } else { System.err.println("Unknown error: " + ex.getMessage()); } } {code} On the flip side using SftpClient and SftpDirEntryIterator, an SftpException is throw in the constructor of SftpDirEntryIterator. This makes easy to determine that cause of the error for invalid permissions. So wondering if the implementation of SftpDirectoryStream can be improved throw SftpException in the constructor? {code:java} try (SftpDirEntryIterator pathIterator = new SftpDirEntryIterator(sftpClient, remotePath)) { while (pathIterator.hasNext()) { DirEntry dirEntry = pathIterator.next(); ... } } catch (SftpException ex) {} {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@mina.apache.org For additional commands, e-mail: dev-h...@mina.apache.org
