Welcome Tracy Miranda
- Been with Eclipse for quite long, Eclipse CDT initially, but also Eclipse Sience and IoT recently
- Based just outside London - Kichwa Coders
Wayne: Updating Legal Docs
- Started revising the Guide to Legal Docs with the IP Advisory Committee
- Thinking about an alternative for file headers, for project who don't want to put company names there
- Meant as an alternative, not a replacement
- Generalizing some docs to be less specific for Eclipse Plugins (example: about.html -> notices file)
- Revising the SUA - Eclipse is the only OSS Community that has such a thing, is it still useful?
- Currently it is very technology specific for Platform (Plugins, Features) - When generalizing it, found that there is not too much it actually says when there's nested licenses in the downloads anyways
- Been investigating SPDX for tracking licenses
Marcel: Neon.3a - How to get the process rolling
- Neon.3 issues were discovered on March 30, why is the problem still out there?
- The fix seems to be in progress (again) now - are we good or is there still work to be done?
- AC and Project Leads should probably be more active to avoid broken software - today, we get 2-3 bug reports daily
- Ed: Packages contain a subset of things, and the packages didn't show the problem - it only occurred after installing add-ons - so it wasn't that screamingly obvious
- JEE confimed - no errorlog entries
- Martin: Reported bug 514257 against Oxygen M6 committers package, but haven't seen the issue in Neon packages
- To-date, we are unsure whether anything we try today would actually fix the issue!
- Ed: We don't know exactly what people installed / updated; Unmodified Neon.3 packages are probably good
- Marcel has some reproducable cases from people who tried to install add-ons. Error reporting could include the list of installed bundles (and probably install history) to error reports, would that help?
- Martin used similar collected logs in the past:
- Unsure whether Errorlog entries really print an unresolvable state, or just that the resolver didn't come up with a resolution; having fewer choices of bundles to wire against certainly simplifies the problem; adding constraints probably makes it harder.
- Either way, it could still show up somewhere else if people install add-ons
- Ideally, the resolver would wire things correctly - or assert that it has an unresolvable problem.
- If we could get back to the state we had in Neon.2, that would perhaps be good enough for Neon (hoping that the Oxygen resolver really improves things)
- Which project actually brought in the new httpcomponents?
- Alex: Docker tooling updated docker client, which relied on the new version. Does p2 eagerly install things from the release train repo?
- An obvious solution would be reverting to the Neon.2 version of docker, to avoid getting the additional httpcomponents into the release train repo.
- Ed: Packages contain a subset of things, and the packages didn't show the problem - it only occurred after installing add-ons - so it wasn't that screamingly obvious
- SUMMARY: AC recommends getting back to the Neon.2 state of httpcomponents, then get input from Fred Bricon.
- Document a couple scenarios for testing (Ed: EGit has a couple similar wiring issues related to logging)
- Will discuss next steps on the mailing list.
- Would it help removing Neon.3 from the composite? - Stop-shipping is a very drastic measure, and would need to be decided by the Planning Council
- In the future, we should be more concerned about quality before shipping things
Infrastructure Updates
- Infrastructure: Recent improvements + Transparent mirroring - haven't seen things get worse, but haven't seen too much improvements either ... Bugzilla was again out-of-sync just yesterday
- Issue had also been discussed at the Board level
- Ed also had download / update site problems yesterday (Wednesday)
- Still more resources being put on the problem but may take longer to get really stable
- Denis - overview of recent improvements:
- One of the biggest pain point on Build was the proxy on build servers; this was finally removed 2 weeks ago
- Yesterday, new storage was provisioned for download.eclipse.org - 14TB up to 22TB and much faster
- Transparent mirroring was enabled - forcing some systems who didn't use mirrors to use them now; this SIGNIFICANTLY reduced bandwidth, so after years we finally have some bandwidth to spare!! - AI Ed please forward details on download timeouts (seemed like a transient thing for about an hour or so)
- OSUOSL monitors eclipse.org for performance and availability, will keep an eye on this
- Anything above 2MB can selectively redirect to mirrors now - anything gzipped is a candidate, including p2 metadata now!!
- If a large xml.xz is redirected to a slow mirror, that could cause timeouts?
- Mirrors are polled for availability every 2 hours - has to have 100% success for 2 weeks before being added to redirect pool
- Mirrors could now fake metadata to serve malicious jars ? - Metadata (artifacts.jar, content.jar) is not digitally signed; but artifacts are digitally signed, and user has to accept the Cert or agree to installing unsigned things.
- If a large xml.xz is redirected to a slow mirror, that could cause timeouts?
General Topics
- Board minutes were approved yesterday, will be published soon
