--------------------------------
Summary: FileUtils.copyToFile backward incompatibility bug
Key: IO-609
URL: https://issues.apache.org/jira/browse/IO-609
Project: Commons IO
Issue Type: Bug
Affects Versions: 2.6
Reporter: Lingchao Chen
Hi,
The following code snippets throw an IOException: Stream closed. It works well
before commons-io 2.6. When I update commons-io to 2.6, it failed. There is a
backward incompatibility bug behind it.
The function code:
{code:java}
public class Demo {
private void backupFile(String srcPath, String entryPath,
ZipOutputStream stream) throws IOException {
ZipEntry zipEntry = new ZipEntry(entryPath);
stream.putNextEntry(zipEntry);
Files.copy(Paths.get(srcPath), stream);
}
private void backupDir(String srcDir, String dstDir, ZipOutputStream
stream) throws IOException {
File dir = new File(srcDir);
for (String path : dir.list()) {
System.out.println(path);
backupFile(dir.getAbsolutePath() + File.separator + path,
dstDir + File.separator + path, stream);
}
}
public void backup(String name) throws IOException {
Files.createDirectories(Paths.get("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection"));
ZipOutputStream stream = new ZipOutputStream(
Files.newOutputStream(Paths.get("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp"
+ File.separator + name)));
try {
backupDir("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp",
"meta" + File.separator + "tables", stream);
stream.closeEntry();
} finally {
stream.close();
}
}
public void restore(String name) throws IOException {
ZipInputStream stream = new ZipInputStream(
Files.newInputStream(Paths.get("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp"
+ File.separator + name)));
try {
ZipEntry entry;
while ((entry = stream.getNextEntry()) != null) {
FileUtils.copyToFile(stream, new
File("/Users/chenlingchao/eclipse_projects/workspace/BBI.BugDetection/tmp" +
File.separator + entry.getName()));
}
} finally {
stream.close();
}
}
}
{code}
The test code:
{code:java}
@Test
public void TestDemo() throws IOException{
Demo test = new Demo();
test.backup("test.zip");
test.restore("test.zip");
}
{code}
