Summary: Tar decompression - Inconsistent entry size
Key: COMPRESS-528
URL: https://issues.apache.org/jira/browse/COMPRESS-528
Project: Commons Compress
Issue Type: Bug
Affects Versions: 1.20
Reporter: Maksim Zuev
Attachments: InconsistentSize.tar
Expected that
{{[getSize|https://commons.apache.org/proper/commons-compress/javadocs/api-1.20/org/apache/commons/compress/archivers/tar/TarArchiveEntry.html#getSize--]()
}}returns the size of byte array read from ArchiveInputStream
To reproduce run this Kotlin code(InconsistentSize.tar is in the attachment).
It fails with exception
Exception in thread "main" java.lang.IllegalStateException: 19 expected but 0
found

import org.apache.commons.compress.archivers.ArchiveStreamFactory
import java.io.File
fun main() {
val tar = File("InconsistentSize.tar")
ArchiveStreamFactory().createArchiveInputStream("tar",
tar.inputStream()).use { ais ->
val expected = ais.nextEntry.size
val actual = ais.readAllBytes().size.toLong()
check(expected == actual) { "$expected expected but $actual found" }
}
