Stefan Bodewig commented on COMPRESS-565: ----------------------------------------- Yes, it might be open source (actually it most probably leaves the archive handling to the classes in .NET Framework or Core which may delegate to to Windows native libraries on Windows and zlib on non-Windows platforms), but that doesn't mean figuring out where the errors is would be easy ;) Unfortunately the full error isn't really helpful, I was hoping it would say what exactly it doesn't like about the local file header. Sorry for bothering you. > Regression - Corrupted headers when using 64 bit ZipArchiveOutputStream > ----------------------------------------------------------------------- > > Key: COMPRESS-565 > URL: https://issues.apache.org/jira/browse/COMPRESS-565 > Project: Commons Compress > Issue Type: Bug > Components: Archivers > Affects Versions: 1.20 > Reporter: Evgenii Bovykin > Assignee: Peter Lee > Priority: Major > Attachments: image-2021-02-20-15-51-21-747.png > > > We've recently updated commons-compress library from version 1.9 to 1.20 and > now experiencing the problem that didn't occur before. > > When using ZipArchiveOutputStream to archive 5Gb file and setting the > following fields > {{output.setUseZip64(Zip64Mode.Always)}} > > {{output.setCreateUnicodeExtraFields(ZipArchiveOutputStream.UnicodeExtraFieldPolicy.ALWAYS)}} > resulting archive contains corrupted headers. > *Expand-Archive Powershell utility cannot extract the archive at all with the > error about corrupted header. 7zip also complains about it, but can extract > the archive.* > > The problem didn't appear when using library version 1.9. > > I've created a sample project that reproduces the error - > [https://github.com/missingdays/commons-compress-example] > Issue doesn't reproduce if you do any of the following: > > # Downgrade library to version 1.9 > # Remove > output.setCreateUnicodeExtraFields(ZipArchiveOutputStream.UnicodeExtraFieldPolicy.ALWAYS) > # Remove output.setUseZip64(Zip64Mode.Always) and zip smaller file (e.g. 1Gb) -- This message was sent by Atlassian Jira (v8.3.4#803005)
