Native zlib libraries (original) (raw)

The zip64 support (total_in/out) part probably can be done at Java level (ignore the total_in/out in z_tream_s). Need to remove this dependency. Will take a look later.

-- Azeem Jiva @javawithjiva We have this in IcedTea (USESYSTEMZLIB=true) and intend to get it upstream. However, I don't see how this is related to HotSpot, as the zlib usage is in the jdk tree. I think we need to (re)start the discussion on core-libs-dev with a view to eliminating the patches that the JDK has to zlib, see: http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/tip/src/share/native/java/util/zip/zlib-1.2.5/patches/ChangeLogjava One of these changes relates to the zip64 support and I believe there are corner cases when inflating or deflating >2GB that won't work if using the system zlib. Sherman will likely recall the details. Given that the new build already supports using the system zlib (at least on Linux) then it would be good to sort this out so that it just works. -Alan
