tomaswolf opened a new issue, #384: URL: https://github.com/apache/mina-sshd/issues/384
### Version master ### Bug description The following code fails: ``` SftpFileSystemProvider provider = ...; FileChannel channel = provider.newFileChannel(somePath, StandardOpenOptions.READ); FileLock lock = channel.lock(from, to, true); ``` This creates a read-only file channel and tries to obtain a shared (read) lock. It fails with an Apache MINA sshd server returning a general failure. ### Actual behavior Obtaining the lock throws an exception. ### Expected behavior The lock can be obtained (if there are no conflicts). ### Relevant log output _No response_ ### Other information - File locking is available only in SFTP v6. Current code doesn't check for this. - The client always sends zero as lock flags; it should send the appropriate read/write lock flags. - The server ignores flags passed, and also does not check for the SFTP version. - Shared read locks can obtained only if the channel was opened for reading; exclusive write locks only if the channel was opened for writing. The client could check this condition before even making any server call. -- This is an automated message from the Apache Git Service.
