Subject RE: [crypto][chimera] Next steps
Date Fri, 26 Feb 2016 02:24:45 GMT
Come back to clear out the codebase and IP concerns.

[Benedikt] I still have concerns about the IP, since this seems to be an Intel codebase.
I have checked this. Chimera was developed as Apache 2 License from ground up. Agree with
Jochen that the license matters.
Internally, this was approved as part of larger open source efforts on Apache Hadoop and related
projects in Intel. We have IP plan considered as part the open source process.

As to the codebase, such as the package name is com.intel prefixed, it was technical decision
when using com.intel.chimera as the package prefix. We original planned to use org.apache.chimera
prefix. But we found that we couldnot publish org.apache. grouped artifacts to maven central
repository, which needs to somewhat ownership for org.apache domain.

To resolve the codebase problem, once all things are ready from Commons, we rename in a branch.
And the branched code can be copied into Commons github as final. 

Thanks,
Haifeng

Yes, current implementation will fallback to JCE Cipher if native is not available.

[Uma] we would fix up IP issues if any sooner. If you see all the code file license header
is with Apache License files.
The current repo and package structure there with name Intel. I will check with Haifeng on
resolution of this.
I will work with this ASAP for clear this out.

Thanks,
Haifeng

Thanks all for the valuable feedbacks and discussions.
Here are my replies for some of the questions..
[Mark wrote]
It depends. I care less about the quality of the code than I do about the community that comes
with it / forms around it. A strong community can fix code issues. Great code can't save a
weak community.
[uma] Nice point. Fully agreed to it.


[Jochen wrote]
Therefore, I suggest that you provide at least fallback implementations in pure Java, which
are being used, if the JNI based stuff is not available (for whatever reason).
[Uma] Thank you for the suggestion Jochen, If I understand your point right,  Yes its there
in Hadoop when we develop.
Here is the JIRA HADOOP-10735 : Fall back AesCtrCryptoCodec implementation from OpenSSL to
JCE if non native support.

The same should be there with Chimera/Apache Crypto.


[Benedikt]
I still have concerns about the IP, since this seems to be an Intel codebase. I do not have
the necessary experience to say what would be the right way here. My gut feeling tells me,
that we should go through the incubator. WDYT?
And [Jochen wrote]
"An Intel codebase" is not a problem as such. Question is: "Available under what license?"

[Uma] we would fix up IP issues if any sooner. If you see all the code file license header
is with Apache License files.
The current repo and package structure there with name Intel. I will check with Haifeng on
resolution of this.


[Jochen wrote]
So, have the Chimera project attempt to resolve them quickly. If
possible: Fine. If not: We still have the Incubator as a possibility.
[Uma] Agree. We would resolve on this points in sooner.


Regards,
Uma
