EMF-IncQuery 1.1.0 and VIATRA 0.8.0 release delayed due to Xtext 2.9 delay
- TODO: talk with Itemis to get timely notice on such delays
Bugzilla status: https://bugs.eclipse.org/bugs/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&classification=Modeling&columnlist=assigned_to%2Cbug_status%2Cshort_desc%2Ctarget_milestone%2Cversion&list_id=12976178&order=target_milestone%2Cversion%2Cpriority%2Cbug_severity&product=Incquery&query_based_on=IncQuery%20active%20bugs&query_format=advanced
Java 6 vs Java 7
- Java 6 is long dead
- Increasingly difficult to keep CI on Java 6
  - There are ways to compile Java 6 compatible code when running Maven with newer JDK
- Eclipse Platform already moving to Java 8 with Neon
- However, our main dependencies (EMF, Xtext) are still compatible with Java 6
Runtime dependencies:
- internal restrictions:
  - https://git.eclipse.org/r/#/c/58887/
- do not re-export guava (not singleton, known problems)
  - https://bugs.eclipse.org/bugs/show_bug.cgi?id=480627
  - https://git.eclipse.org/r/#/c/58945/
- should we allow Xtend or avoid it
  - If avoid: currently rete.recipes has minor Xtend code easily replaceable and localsearch has PConstraintInfo that can also be replaced with plain Java
  - If allow: using xtend.lib or xtext.xbase.lib (which re-export guava) could replace all guava dependencies
IncQuery.net migration status

Minutes

release delayed to Nov 12th due to Xtext release
bugzilla review: some small bug issues will be postponed
incquery.net migration
- TODO Ábel: evaluate remaining pages for migration
runtime dependencies
- merge and see if any test projects fail
Xtend in core
- no changes planned: do not overuse but otherwise no effort on cleaning now
Java version update
- for 1.2, we will move up to Java 7
EIQ-Sirius benchmark
- hard to measure due to caching
- basic result: on model change, AQL evaluation is executed when the transaction is committed, while EIQ evaluation is much faster (and is performed during modification)
  - AQL can be several seconds vs EIQ less than 100 ms
