[DONE - no response] Agenda - Build Server - Release - ImageN Update - Cross project PR checks - PR templates - Switching from Jira to Github for issue tracking - Chit chat 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 <https://trac.osgeo.org/osgeo/ticket/2306#ticket>) 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! :-D - 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: - https://github.com/eclipse/imagen 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 <https://trac.osgeo.org/osgeo/ticket/2306#ticket>) Chit chat Happy Tuesday everyone...
