A Kelday commented on COMPRESS-514: ----------------------------------- [~ggregory] for what it's worth, that the PR in. > SevenZFile fails with encoded header over 2GiB > ---------------------------------------------- > > Key: COMPRESS-514 > URL: https://issues.apache.org/jira/browse/COMPRESS-514 > Project: Commons Compress > Issue Type: Bug > Components: Archivers > Affects Versions: 1.20 > Reporter: A Kelday > Priority: Minor > Attachments: HeaderChannelBuffer.java > > > When reading what some may call a large encrypted 7zip file (1.2TB with 22 > million files), the read fails at the header stage with the trace below. Is > this within the spec? I've written some code to handle it, because I did > actually need to extract the file in java. If that's of any use I can provide > it (it's a naive wrapper that just pages in a buffer at a time). > > {code:java} > Exception in thread "main" java.io.IOException: Cannot handle > unpackSize2416988886 > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.assertFitsIntoInt(SevenZFile.java:1523) > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.readEncodedHeader(SevenZFile.java:622) > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.initializeArchive(SevenZFile.java:532) > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.readHeaders(SevenZFile.java:468) > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.<init>(SevenZFile.java:337) > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.<init>(SevenZFile.java:129) > at > org.apache.commons.compress.archivers.sevenz.SevenZFile.<init>(SevenZFile.java:116) > {code} > 7zip itself can also open it (and display/extract etc.), here are the stats: > > > {code:java} > Size: 2 489 903 580 875 > Packed Size: 1 349 110 308 832 > Folders: 40 005 > Files: 22 073 957 > CRC: E26F6A96 > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
