DO NOT REPLY [Bug 52414] New: Add compression ratio to gzip task

https://issues.apache.org/bugzilla/show_bug.cgi?id=52414

             Bug #: 52414
           Summary: Add compression ratio to gzip task
           Product: Ant
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Core tasks
        AssignedTo: notifications@ant.apache.org
        ReportedBy: berry120@gmail.com
    Classification: Unclassified


At the moment you can't select the level of compression you want on the gzip
task - this would be useful in certain scenarios for example compressing
changelogs for Debian packages (lintian throws a warning if it's not using
maximum compression.)

This would be nice to have as a separate attribute.

While I agree this would e a nice feature, it is not feasible for the core task
without rewriting it completely.  The core gzip task is based on
java.util.zip.GZIPOutputStream which doesn't provide any control over the
compression level.

The gzip task of the compress Antlib is a different beast as Conmmons Compress'
trunk has moved away from using GZIPInputStream in order to support files that
contain multipile compressed streams.  It would be possible to re-implement
GZipCompressorOutputStream over there as well and then make the compression
level configurable.  Not that I'd advise you to hold your breath ...
