Hi Sage, > If there is something exceptional that hasn't made it in yet and is low-risk, > plea your case,
We would like to contribute our following code to the nearest stable release Hammer, and we believe that our code has sufficiently low risk. mSHEC : multiple Shingled Erasure Code #3534 https://github.com/ceph/ceph/pull/3534 One of the reasons why we think it has low risk is that we have already finished extended tests shown below assuming a product use case. Test items done: * erasure code plugin I/F tests (TestErasureCodeShec.cc) * exhaustive parity layouts tests (TestErasureCodeShec_all.cc) * thread safety tests (TestErasureCodeShec_thread.cc) * tests on a real ceph cluster - pool creation/deletion - read/write - recovery (up to N multiple failures) Another reason is that the code is just a plugin, which is completely isolated from the core of Ceph and has no risks for users who do not need to use it.

This means we're not merging new features until we have a handle on the testing and the QA results are looking good. Specifically: - There is a 'hammer' ceph.git branch. Please target any bug fixes at this. - The 'next' branch is deleted for the time being (see above) - Do not merge any new features to master; not yet. It's too confusing and we have enough work to do stabilizing things. - There are still several pull requests open that are bug fixes and target master that should get merged once they are tested, so we will probably merge hammer and master together periodically to avoid doing all the merged manually. (Another reason not to merge any new code into master that does not target hammer.) - We're using the 'hammer' milestone on github to track what to pay attention to. Please help keep it in sync with the open pull requests that are hammer-bound vs future work for infernalis. If there is something exceptional that hasn't made it in yet and is low-risk, plea your case, but no promises. Bribery in the form of fixes for open bugs can be effective. :) Thanks! sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
