Stefan Bodewig commented on COMPRESS-189:
-----------------------------------------
Hmm, I'll look around the website in time before the next release to asses
whether it really is suitable to be included. Maybe there is an easy way to
create a similar testcase ourselves.
As for COMPRESS-205, I've seen it - it will take some time until I get to it.
> ZipArchiveInputStream may read 0 bytes when reading from a nested Zip file
> --------------------------------------------------------------------------
>
> Key: COMPRESS-189
> URL: https://issues.apache.org/jira/browse/COMPRESS-189
> Project: Commons Compress
> Issue Type: Bug
> Components: Archivers
> Affects Versions: 1.4.1
> Environment: JDK 1.6 64-bit, Windows 7
> Reporter: Daniel Lowe
> Priority: Blocker
> Fix For: 1.5
>
>
> When the following code is run an error "Underlying input stream returned
> zero bytes" is produced. If the commented line is uncommented it can be seen
> that the ZipArchiveInputStream returned 0 bytes. This only happens the first
> time read is called, subsequent calls work as expected i.e. the following
> code actually works correctly with that line uncommented!
> The zip file used to produce this behavious is available at
> http://wwmm.ch.cam.ac.uk/~dl387/test.ZIP
> If this is not the correct way of processing a zip file of zip files please
> let me know. Also I believe whilst ZipFile can iterate over entries fast due
> to being able to look at the master table whilst ZipArchiveInputStream
> cannot. Is there anyway of instantiating a ZipFile from a zip file inside
> another zip file without first extracting the nested zip file?
> ZipFile zipFile = new ZipFile("C:/test.ZIP");
> for (Enumeration<ZipArchiveEntry> iterator = zipFile.getEntries();
> iterator.hasMoreElements(); ) {
> ZipArchiveEntry entry = iterator.nextElement();
> InputStream is = new BufferedInputStream(zipFile.getInputStream(entry));
> ZipArchiveInputStream zipInput = new ZipArchiveInputStream(is);
> ZipArchiveEntry innerEntry;
> while ((innerEntry = zipInput.getNextZipEntry()) != null){
> if (innerEntry.getName().endsWith("XML")){
> //zipInput.read();
> System.out.println(IOUtils.toString(zipInput));
> }
> }
> }
