[Bug 1507244] Re: Missing erasure coding plugins for jerasure/neon and shec

[Steve Tsai]

I installed the package to Wily armhf platform and the issue was fixed.
The following erasure libraries are installed and there are no symbolic
links now.

Title:
  Missing erasure coding plugins for jerasure/neon and shec

Status in ceph package in Ubuntu:
  Fix Released
Status in ceph source package in Vivid:
  New
Status in ceph source package in Wily:
  Fix Committed
Status in ceph source package in Xenial:
  Fix Released

Bug description:
  [Impact]
  Neon optimized jerasure plugin is built but not included in packages; this results in use of the un-optimized jerasure plugin in this use case.

  Likewise the SHEC based plugin is built, but not shipped.

  A number of dangling symlinks are also installed in the ceph package.

  [Test Case]
  sudo apt-get install ceph
  ls -l /usr/lib/*/ceph/erasure-code
     <missing libec_jerasure_neon.so>
     <missing libec_shec.so>
     dangling symlinks.

  [Regression Potential]
  Minimal; The proposed fix just ensures that the missing plugins are built with a unversioned .so extension, and drops the dangling symlinks from the install.
