GZip corrupt files are partially unzipped
-----------------------------------------
Key: COMPRESS-84
URL: https://issues.apache.org/jira/browse/COMPRESS-84
Project: Commons Compress
Issue Type: Bug
Affects Versions: 1.0
Environment: Apache Maven 2.2.0 (r788681; 2009-06-26 15:04:01+0200)
Java version: 1.6.0_14
Java home: /opt/jdk1.6.0_14/jre
Default locale: fr_FR, platform encoding: UTF-8
OS name: "linux" version: "2.6.30.5-28.rc2.fc11.i586" arch: "i386" Family:
"unix"
Reporter: Florent Charton
While trying to decompres gzipped data with random removed bytes, no exceptions
are thrown. Same file with zcat command line utility produces error below
{noformat}gzip: badfiles-red-64/data.txt.gz: invalid compressed data--crc error
gzip: badfiles-red-64/data.txt.gz: invalid compressed data--length error
{noformat}
The code below should throw an exception about corrupted file
{code:title=Sample extraction code}
CompressorInputStream cis = null;
try {
cis = new CompressorStreamFactory().createCompressorInputStream(
"gz", new FileInputStream("badfiles-red-64/data.txt.gz"));
} catch (CompressorException e) {
// This will never happen unless "gz" is changed 2 lines above
log.error(e.getMessage(), e);
throw new ProcessingException(e);
}
try {
while (cis.read() > 0) {
}
} catch (IOException e) {
log.error(e.getMessage(), e);
throw new ProcessingException(e);
}
{code}
