Thursday, May 28, 2015 around 12:40pm PST: 497da30e to be deployed (Reverted)

 * : Support subst: of transclusion blocks in the parseFragment API endpoint
 * DOMDiff: For  id properties in data-mw, fetch HTML and compare DOMs to detect edits to  s without requiring clients to dirty the   nodes

 * Code cleanup and fixes in mediawiki API request handling
 * Refactor request default options into ApiRequest.prototype.request
 * Strip UTF8 BOM so that JSON.parse doesn't throw
 * Ignore modulemessages in api=parse result

This is the same as yesterday's attempted deploy, which we had to defer due to.

Reverted after observing an outgoing network traffic spike on our canary deploy machine (wtp1001). Suspected to be due to stats or logging misconfiguration. This is because of a typo in one of the parsoid-config properties that determines the heap usage sample interval. Because of the typo, instead of sending heap usage samples every 5 mins, parsoid was sending samples all the time. This caused the network spike seen on wtp1001.

Wednesday, May 27, 2015 around 1pm PST: 497da30e to be deployed (Cancelled)
Because of, we cannot currently test the deploy by looking at VE edits to see that we didn't break anything by examining wikitext diffs. Parsoid deploys are paused till that ticket is resolved and a patch is deployed to production.

Deployment cancelled. We found some regressions and the fixes for them are still going through round trip testing at this time. So, we'll get these out on Wednesday.

Friday, Feb 6, 2015, around 9:10pm PST: Hotfix of cherry-pick
Jan 28, 2015 deploy of exposed a longstanding bug in Parsoid which was fixed by. On some pages, due to where some templates weren't being expanded, the Attribute Expander was effectively being asked to re-expand the template over and over again in an infinite loop. This was being triggered on a few enwiki pages today that was causing processes to get stuck without being restarted. This hotfix prevents the infinite loop.

Friday, Feb 6, 2015, around 11:20am PST: Hotfix of cherry-pick
A bug in our process restart (on fatal errors) was exposed by unrelated bugs in our parse pipeline which manifested as stuck processes on the cluster. This hotfix fixes that by ensuring that fatals continue to restart processes.

Wednesday, Feb 4, 2015, around 1pm PST: ✅

 * Switch to using the compression package instead of the outdated version bundled with connect. In testing, that cleared up the memory leak noticed since the Jan. 15th deploy.
 * Some cleanup including:
 * Changing a few on handlers to once.
 * Using request's qs option for apiargs instead of stringifying those manually.
 * Better error handling for config requests.

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
 * : Cleanup of behavior switch production
 * Updates to wikitext serializer to simplify and enable more robust wikitext escaping

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.

Monday, Jan 12, 2015 around 1pm PST: ✅

 * Include location of titles in timeout logs
 * Tweaks to Parsoid's cite port to generate identical ref ids as native cite implementation
