-----------------------------
Summary: SFTP download reopen files issue
Key: SSHD-229
URL: https://issues.apache.org/jira/browse/SSHD-229
Project: MINA SSHD
Issue Type: Improvement
Affects Versions: 0.8.0, 0.9.0
Reporter: Jr. John
Fix For: 0.9.0, 1.0.0
org.apache.sshd.server.sftp.SftpSubsystem.java
It's always reopen and close file when use sftp download files.
public int read(byte[] data, long offset) throws IOException {
if (input != null && offset != inputPos) {
IoUtils.closeQuietly(input);
input = null;
}
if (input == null) {
input = file.createInputStream(offset);
inputPos = offset;
}
int read = input.read(data);
inputPos += read;
return read;
}
I modify to bellow. it's open file one time when download. And faster 10x then
old code.
public int read(byte[] data, long offset) throws IOException {
if (input == null) {
input = new
RandomAccessFile(((NativeSshFile)file).getPhysicalFile(), "r");
}
inputPos = offset;
input.seek(inputPos);
int read = input.read(data);
inputPos += read;
return read;
}
