Antoine Toulme commented on BUILDR-621:
---------------------------------------
Buildr monkey-patches CentralDirectory to write entries in alphabetical order.
See lib/buildr/packaging/zip.rb, line 33.
However, your change is still needed since ZipTask.create_from is using the zip
stream directly.
> ZipTask creates zip file with entries not sorted by path causing very slow
> unzipping.

> Key: BUILDR-621
> URL: https://issues.apache.org/jira/browse/BUILDR-621
> Project: Buildr
> Issue Type: Bug
> Components: Packaging
> Affects Versions: 1.4.7
> Reporter: Russell Teabeault
> Fix For: 1.5
>
>
> ZipTask#create_from iterates through the file_map and creates the zip with
> the entries in no particular order. With a large zip file this can
> dramatically slow down unzipping since the physical disk has to do much more
> random access.
> Currently the code does:
> file_map.each do |path, content|
> Doing something such as the following would probably be better:
> paths = file_map.keys.sort
> paths.each do |path|
> content = file_map[path]
