Meeting summary
---------------

* odlparent-5.0.0  (rovarga, 17:06:08)
  * LINK:
    https://jira.opendaylight.org/projects/ODLPARENT/versions/10825 is
    the tracker  (rovarga, 17:06:16)
  * most of the targeted issues are in review  (rovarga, 17:06:27)
  * there are couple of patches we want in 4.0.10, will wait for them to
    land before branching  (rovarga, 17:06:44)
  * not sure about https://jira.opendaylight.org/browse/ODLPARENT-176
    (rovarga, 17:08:26)
  * the bundle name is useful in general  (rovarga, 17:08:37)
  * and this can always be tuned in a particular deployment  (rovarga,
    17:08:49)
  * most notably, high-log-deployments will probably end up using
    logstash or something of that kind to capture the logs (and sift
    through them)  (rovarga, 17:09:17)

* karaf-4.2.3  (rovarga, 17:16:27)
  * karaf-4.2.3 bumps javax.annotation version to 1.3.0  (rovarga,
    17:16:41)
  * and multipatch fails of the dreaded package resolution conflicts
    (rovarga, 17:19:08)
  * we may need to postpone 4.2.4 upgrade until we have sorted out oour
    JSR305 story, at least in APIs  (rovarga, 17:19:28)

* RFC8040 and filter  (rovarga, 17:19:43)
  * the question is whether the new RESTCONF supports
    https://tools.ietf.org/html/rfc8040#section-4.8.4 filters  (rovarga,
    17:20:42)
  * RFC8040 seems to specify filters only for notification streams, not
    for individual GETs  (rovarga, 17:26:34)
  * since they are XPath based, we are pretty sure they are not
    implemented for GETs even as an extension  (rovarga, 17:26:54)

* multipatch issues  (rovarga, 17:27:22)
  * the problem is with topic=fooBar, where the latest tag is checked
    out and the patches are checked out on it  (rovarga, 17:28:54)
  * for odlparent master patches cannot been cherry-picked on top of
    odlparent-4.0.9 tag  (rovarga, 17:29:12)
  * LINK:
    https://jenkins.opendaylight.org/releng/view/integration/job/integration-multipatch-test-sodium/9/
    (rovarga, 17:29:59)
  * the best thing would be to introduce topic:foo to perform a checkout
    (rovarga, 17:33:24)
  * ACTION: LuisGomez will try to come up with a solution for odlparent
    only  (rovarga, 17:34:13)

* tell-based protocol  (rovarga, 17:36:10)
  * ofp testing is still stuck on topology links not being torn down
    (rovarga, 17:36:41)
  * functional testing has only this issue outstanding  (rovarga,
    17:37:46)
  * LINK:
    https://jenkins.opendaylight.org/releng/view/openflowplugin/job/openflowplugin-csit-3node-clustering-perf-bulkomatic-only-neon/
    (LuisGomez, 17:39:06)
  * we have a failure with performance jobs, but that may need tweaking
    (rovarga, 17:40:58)
  * it seems that switching to tell-based protocol by default is
    feasible in Sodium timeframe  (rovarga, 17:45:04)

* NETCONF scale testing  (rovarga, 17:47:46)
  * jmorvay asks about scaling of SB devices  (rovarga, 17:47:59)
  * for a simple test tool, I could attach 10K sessions with 965MiB
    retained heap  (rovarga, 17:48:27)
  * for stable/neon  (rovarga, 17:48:37)
  * with sshd-core-2.2.0 (staged at
    https://git.opendaylight.org/gerrit/#/c/76300/) I could attach 10K
    sessions with 744MiB retained heap  (rovarga, 17:49:27)
  * Bala reports similar results with 10GiB heap and a real device
    (rovarga, 17:49:57)
  * real device == ~70 YANG models  (rovarga, 17:50:14)
  * https://jira.opendaylight.org/browse/NETCONF-590 tracks transport
    layer rework  (rovarga, 17:53:02)
  * which blocks https://jira.opendaylight.org/browse/NETCONF-571
    (rovarga, 17:53:38)
  * which is about 50% of our current static steady-state memory
    overhead (not counting SchemaContext overheads)  (rovarga, 17:56:28)

* anyxml handling in get-config  (rovarga, 17:57:47)
  * Bala reports that it did not seem to work in Carbon  (rovarga,
    17:57:59)
  * it may be a missing bit in yangtools codecs, where we do not handle
    one of the directions  (rovarga, 17:58:30)
  * will follow up after testing a recent version  (rovarga, 17:58:45)



Meeting ended at 17:58:58 UTC.
