Description:
LZ4 compression for Java, based on Yann Collet's work.
This library provides access to two compression methods
that both generate a valid LZ4 stream:

* fast scan (LZ4):
    ° low memory footprint (~ 16 KB),
    ° very fast (fast scan with skipping heuristics in case the
      input looks incompressible),
    ° reasonable compression ratio (depending on the
      redundancy of the input).
* high compression (LZ4 HC):
    ° medium memory footprint (~ 256 KB),
    ° rather slow (~ 10 times slower than LZ4),
    ° good compression ratio (depending on the size and
      the redundancy of the input).

The streams produced by those 2 compression algorithms use the
same compression format, are very fast to decompress and can be
decompressed by the same decompressor instance

is really necessary? i would remove libxxhash stuff when RHBZ#1282063 will be solved

Comment 8 Tomas Repik 2016-02-18 12:50:05 UTC
Now I know why:

The package is really good, only thing is with that bundled xxhash, I don't know if it could be removed later. Here is the review:

Package Review
==============
Legend:
[x] = Pass, [!] = Fail, [-] = Not applicable, [?] = Not evaluated

[?]: Every binary RPM package which stores shared library files (not just
     symlinks) in any of the dynamic linker's default paths, must call
     ldconfig in %post and %postun.
[!]: Package contains no bundled libraries without FPC exception.

Some non-blockers
- no need to remove .jar .class files there are not any
- a typo in the comment on %check section: wast > waste
- no ${libdir} in build.xml ( sed -i 's|${libdir}|%{_libdir}|' build.xml)

the build depends on the architecture of the system according to the library used (lz4), it is not possible that both noarch

Is no necessary for a JNI library

Is no MORE necessary

Seriously? What guidelines do you use?
We use only: 
https://fedoraproject.org/wiki/Packaging:Java
https://fedorahosted.org/released/javapackages/doc/

> - patches should link to upstream bugs/comments/lists
Is no necessary, comments are available and the patches are specific only for Fedora

It is already covered

But you still need the FPC exception right?

The guideline was recently changed ...

Comment 12 gil cattaneo 2016-02-22 18:29:08 UTC
FPC ticket was closed:
Resolution:  nothingtodo
"
Comment:

 FPC no longer has anything to do with bundling.  Please see the current
 guidelines:

 https://fedoraproject.org/wiki/Packaging:Guidelines#Bundling_and_Duplication_of_system_libraries

 Please make sure to add the necessary "Provides: bundled(xxHash) =
 version" to your package.

Comment 13 Tomas Repik 2016-02-23 10:57:03 UTC
All right, I've already (accidentally) set the fedora-review flag to "+" so the package is ready to proceed to next phase.
I would just include the link to the FPC ticket in the spec file anyway.
Thank you.
