Re: [p2-dev] Pack200 compression

Hi MikaÃl,

No, I've received a reply, all good, any help would still be appreciated of course.

Cheers,

Peter.

Peter,

What do you mean by "we might have some more luck if we have a couple of volunteers"? Is this about the lack of replies on jdk-dev or have you been told so in a private thread?

That's ok, we might have some more luck if we have a couple of volunteers, even if the other was not able to put much time in, strength in numbers so to speak.

Cheers,

Peter.

Hi MikaÃl,

I must have been a little tired when I read this the first time. I didn't realise there was an OpenJDK Java implementation of Pack200.

I agree, deprecate the C++ implementation and maintain the standard and java implementation.

Regards,

Peter.

I've only ever lightly dabbled in C++ and that was a long time ago (15 years). It's an option if there are C++ capable and willing volunteers.

Thanks,

Peter.

As far as I understand from http://mail.openjdk.java.net/pipermail/jdk-dev/2018-June/001472.html, you don't necessarily need to start with Harmony implementation as there already is a full (read pack and unpack) Java implementation of pack200. http://hg.openjdk.java.net/jdk/jdk/file/2f2af62dfac7/src/java.base/share/classes/com/sun/java/util/jar/pack


So I guess that one proposal to JEP336 could be: deprecate the c++ native implementation (as this is not used anymore for the JRE) but keep the spec + Java impl.


Then anyone (Peter?) could sign up to maintain it @ openjdk.

WDYT?

I'm not currently a committer, though happy to, if invited. :)

To sum up:

1. The Pack200 clean room implementation written in Java, it can
compress and decompress java bytecode and pack.gz files, it was a
module developed as part of Apache Harmony, AL2 licensed.
2. Oracle owns the Pack200 Standard copyright. https://docs.oracle.com/javase/10/docs/specs/pack-spec.html
3. OpenJDK's Pack200 test compatibility kit, is GPL2 with classpath
exception, (I haven't gone down this road yet, but it's ideal for
testing compatibility, with some modification for the libraries
different api).
4. We won't be implementing any of the Java API's copyrighted by Oracle.


Oracle is deprecating the Pack200 standard and its GPL2 licensed implementation.

Thanks,

Peter.

 Peter should do that as he knows better what he's exactly doing
 ;-). Also, I will be away next week and fully booked today.


Is Peter a committer on any Eclipse.org <http://Eclipse.org> project? I'm afraid if he sends the request without backup from a committer, it will be rejected as "sorry, we only work for Eclipse.org <http://Eclipse.org> projects, and don't do legal consulting for the whole wide world".
