Dmitry created VFS-826:
--------------------------
Summary: SFTP file get content issue for some servers
Key: VFS-826
URL: https://issues.apache.org/jira/browse/VFS-826
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.9.0
Reporter: Dmitry
Some SFTP servers does not allow multiple channels open at same time,
but SftpFileObject always open two if no hacks applied - at first just creates
channel, then creates new channel to fetch type.
Possible solution is to move file type check on top, so underlying code of
getType will 'park' channel and then it will be reused.
{code:java}
protected InputStream doGetInputStream(int bufferSize) throws Exception {
synchronized((SftpFileSystem)this.getAbstractFileSystem()) {
ChannelSftp channel =
((SftpFileSystem)this.getAbstractFileSystem()).getChannel();
InputStream inputStream;
try {
if (!this.getType().hasContent()) {
throw new
FileSystemException("vfs.provider/read-not-file.error", this.getName());
}
inputStream = channel.get(this.relPath);
} catch (SftpException var7) {
if (var7.id == 2) {
throw new FileNotFoundException(this.getName());
}
throw new FileSystemException(var7);
}
return new SftpInputStream(channel, inputStream, bufferSize);
}
} {code}
