Parsoid/Deployments

Planned deployments, linked from Deployments. For a list of past deployments, look for 'parsoid' in Server Admin Log.

See Parsoid to learn how to deploy a new version of Parsoid.

Monday, Feb 2, 2015, around 1pm PST: ✅

 * Set X-Forwarded-Proto when proxying https. This fixes timeouts for ruwikinews which is strict about accepting only https connections.
 * Some performance tweaks to attribute expander to eliminate useless work and useless memory allocation
 * : Fixes to resource module loading URI in the section of Parsoid HTML
 * Fixes to tokenizer to ensure that strings starting with '-' are parsed for directives like language variant markup

Friday, Jan 30, 2015 around 2:35 pm PST: ✅
The Jan 15th deploy where Parsoid started using sitematrix info for configuring wikis was missing special handling for some wikis (commonswiki being one of them). This caused timeouts which in turn repeatedly exercised an existing memory leak. This, in turn, caused a slow buildup of leaked memory on the cluster and a higher than normal cpu load. This special Friday deploy fixed the config issues.

Specifically, the following two patches were deployed:
 * Some special wikis should use the default proxy
 * Strip TLS from sitematrix url if we're using the default proxy

Wednesday, Jan 28, 2015 around 1pm PST: ✅

 * : Correctly handle templates that generate part-attribute and part-content of a DOM node.
 * : Preserve blank template parameters

 * Updates to wikitext serializer to simplify and enable more robust wikitext escaping
 * ,, : Magic link fixes (wt2html and html2wt nowiki handling)

Thursday, Jan 15, 2015 around 1pm PST: ✅

 * ,, : Default WMF wikis served by Parsoid fetched from sitematrix API call
 * : Positional params with = in extlink are serialized as named parameters

On Jan 14th 1:20 pm PST, we reverted Parsoid to older deployed version after dirty diffs were seen during post-deploy testing. It turned out that the dirty diffs weren't related to the Parsoid deploy, but now that those issues have been fixed, we'll revisit the Parsoid deployment on Thursday.
