Error when unpacking app.zip during staging

[tgold]

Recently I got an error when I try to push an app to IronFoundry:

{"cmd":"unzip","args":["C:/IronFoundry/dea_ng/staging/d20130828-1912--8hs0cx/app.zip","@root@/tmp/unstaged" ]}]","exit_status":1,"stdout":"","stderr":"Wrong Central Directory signature\r\n"},"thread_id":3296232,"fiber_id":184674
36,"process_id":1912,"file":"C","lineno":0,"method":"223"}

I digged into the problem and found out that the app.zip coming from the cloud controller is a Zip64 file. The library used by the IronFoundry warden to extract the archive (SharpZipLib) seems to have issues with Zip64 archives.

I currently use a workaround such that I force the cloud controller (in lib/cloud_controller/app_package.rb) to not use Zip64 (using the -fz- option). Then it works without problem.

I just wonder why this happens now (I now have v138 of CF) where it didn't happen before. I can live with the workaround, I just wanted to make you aware of this issue.
