Subject Re: Inclusion of .class files within a Apache Source Release
Date Tue, 03 Jan 2017 18:07:53 GMT
I propose to simply rename it to .noclass and we are done ;P

> Hi Romain,
> AIUI, it isn't a "no binary" policy, it is a "no compiled sources" policy.  Distributing
a compiled binary puts the responsibility of the effects of executing that code on the ASF
and should scare away customers.  You are taking a big chance by running the source build
script if it executes that .class file if you can't verify it came from the source you said
it did.    Sure a customer might have a bad tool chain that compiles the sources into a bad
binary, but that is not the ASF's responsibility.
> About "no binary" vs "no compiled sources": it leads to the trust or not of the downloaded
package which is guaranteed - between others - by the signing we do of the package, not by
the extension (as explained it is easy to exploit a .png containing a .class). If you can't
trust the signing of the source bundle then .class is the least issue you can get I fear so
really not an issue.
> Also for this particular case: these .classes are in *test* resources so not used until
you run tests and if you do so you likely want to have them. When I spoke of bad tool chain
it was about the project itself, not the user: if you don't use that trick you need to generate
classes in the build but NOT in the test-classes folder to ensure these classes are NOT in
the classpath (point of having them as resources). Most of solutions would break IDE support
and would make entry cost of the project high for a poor gain, that is why it got done this
way. Also note that these .class are in the "wrong" folder regarding their package and are
NOT classes the way they are stored. Without some actual file copy you will not load them
by default even if in the classpath. So running them needs some knowledge on them which reduces
again the risk.

things (not breaking dev tooling).

we have these classes only for some part of some tests and not the whole test phase. it also
breaks IDE support to do it this way and reduce contributions capabilities but that's another
