Solr releases 4 times a year

gforcada commented 5 years ago

With an open question: do we really need to test every version of the 7.x release line? :sweat_smile: which ones would be relevant? The latest always makes sense, does Solr has some LTS policy of the sorts? :thinking:

According to this thread: http://lucene.472066.n3.nabble.com/Solr-LTS-and-EOL-td4403843.html it seems that no, Solr does not release 4 times a year (although all 7.x releases have happened every 3 months from each other), it might have been a coincidence.

What they do clearly state is that:

a new major release (i.e. 8.0) means the complete EOL of the previous previous major release line (i.e. 6.0)
any new minor release (i.e. 7.7.0) means the complete EOL of any previous minor release (i.e. 7.6.x, etc)

So I guess that for (Plone/c.solr) historical reasons the 4.x and 5.x tests make sense. The 6.x still gets maintenance, and anything but 7.6.0 on the 7.x release line is unsupported.

Should I refactor this patch to keep only 4/5/6/7.4/7.6? :thinking: (the 7.4 due to being the what was up until now the latest being tested).

@gforcada thanks! I basically just added the releases that we at kitconcept use. The builds are really fast on Travis and the versions are cached. Therefore I think we can test multiple versions and the full minor versions of the 7.x. In the past I encountered breaking changes in minor Solr versions. This shouldn't happen but it did. Therefore I'd like to test more than what might be necessary according to the Solr core devs.
