Actions
-
Torben: Report back to Mailing List about Nightly Build status tomorrow
-
Jody: Talk to OSGeo about setting up a forum (Discourse?) on OSGeo hardware for discussion (done #2306)
Build Server
Build server in maintenance, taken offline and being rebuilt using Jenkins 2. Taking longer than estimated (to set up mavn, java, etc…).
Blocking:
-
Nightly builds is the real pain point keeping all PRs from being merged
-
Can we prioritize just this point as a blocker? “yes”
-
Twitter complained about not having access to community module builds (huh!)
Options:
-
Consider balancing this across GeoSolutions / OSGeo hardware?
-
GeoSolutions offers dedicated hardware for nightly builds.
-
OSGeo could also provision hardware (and may have some already).
-
Jody: To ask what is available.
-
Scale back to only compile community modules, make it obvious in docs that you need to compile this stuff yourself → noope!
-
Note these downloads are transient were not really expected to be kept
Release
Release next week? May 18th +/-:
-
Blocked by Build Server!
-
May 16th: Kevin, James Hughes (requests backup), Torben helps with build server
-
If not we will have to reschedule when build server is available
James is looking at the jira release script during the sprint.
-
Initially adapt readme instructions?
-
release notes? Edit file before you make the release.
May consider porting the geoserver release script for GWC?
- Kevin is comfortable with the Ruby Script, but hard for others …
GeoServer website release automation ideas / discussion.
ImageN Update
Code base is up:
IP review ongoing:
Update is a search and replace to change package names, and everything else compiles.
We need to coordinate this across our roadmap.
Q: How to handle JAI-EXT?
-
Option 1: Search and replace on master, subsequent releases use ImageN
-
Option 2: Add an imagen-ext module to ImageN project
Roadmap research:
- Make a branch on all the projects and try it out
Q: JAI SPI?
- One method that registry everything …
Q: How is it working on Java 11?
- It does not compile, when it uses Java 8 classes those codec
Codecs:
-
Are in a seperate jar, we would make that only work in Java 8
-
Java 11 already has a TIFF codec
Q: How to handle classses JAI with static methods?
-
Options A: Keep JAI as is (a bit odd but it is done already!)
-
Options B: Make ImageN, and then make JAI extend ImageN (and deprecate JAI).
Q: tutorials and examples
- We got it - https://github.com/eclipse/imagen/pull/11
Q: ImageN stuff to go out?
-
Not in general as we want an open source copy
-
Specifically looking up internationalization in the jre/ext folder ← need to remove
-
Remote is based on RMI ← keep for those migrating?
-
Renderable ← keep for those migrating?
Q: JAI-EXT functionality to go in now?
-
concurrent registry
-
based on Java stuff ← read write locks!
-
title cache is slow
-
based on synchronized
-
Switch to Java concurrent would be the key improvement
-
new concurrent tile cache?
-
Uses Google Cache Concurrent
-
import com.google.common.cache.Cache;
-
import com.google.common.cache.CacheBuilder;
-
import com.google.common.cache.RemovalCause;
-
import com.google.common.cache.RemovalListener;
-
import com.google.common.cache.RemovalNotification;
-
import com.google.common.cache.Weigher;
-
performance is much better under concurrent load
-
scales a lot better under concurrent load
-
cleans up the titles from a specific image much faster
Cross project PR checks
If we had a build server we could set this up …
-
discussion covering how difficult this is:
-
Need a geotools PR to be tested in GWC and GeoServer
-
Example from Checkstyle https://github.com/checkstyle/checkstyle/pull/6762 (uses Circle-CI for regression testing)
-
James is considering looking at that this week …
PR templates
What are PR templates?
https://github.com/geoserver/geoserver/pull/3490
Switching from Jira to Github for issue tracking
Twitter feedback that we make it too difficult …
-
Mailing lists are too old, request forum that they do not need to sign in …
-
Move to stack exchange? We are already https://gis.stackexchange.com/questions/tagged/geoserver
-
That is a Q&A format so not quite the same
-
Not flooded by email (like user list)
-
Want to make the question without any delay
-
OSGeo hosts NextCloud (which does offer Forum)
-
Also folks expect a chat (like slack or gitter)
-
Twitter also offered to set up a forum https://discourse.mozilla.org/
-
New account to report bug on Jira is too difficult …
-
Can we make it use OSGeo user id ← probably longer delay? Bad idea …
-
Assume folks have a GitHub account github issues may work
-
GitHub issues did not allow attachments previously
GitHub issues now support attachments (this was a blocker):
-
White list of file types (images, pdf, zip)
-
25 MB size limit
-
Offer of 5 days to port issues …
Discussion:
-
At least we are not IRC
-
We do not really need more “participation” we need more “developers”
-
Andrea is not sold, but not totally against …
Action:
- Jody ask osgeo about hosting forum software (#2306)
Chit chat
Happy Tuesday everyone…
