Mentioned in SAL (#wikimedia-operations) [2017-06-26T22:34:35Z] <legoktm@tin> Synchronized php-1.30.0-wmf.6/extensions/Linter/includes/ApiRecordLint.php: Add debug logging for missing 'dsr' - T168900 (duration: 00m 43s)
Now we are getting this:
Warning: Invalid operand type was used: array_slice expects an array or collection as argument 1 in /srv/mediawiki/php-1.30.0-wmf.6/extensions/Linter/includes/ApiRecordLint.php on line 76
But no sign of the debug message.
ok I found one:
dsr for Проект:Переводы/Запросы_на_перевод @ rev 86208206, for lint: obsolete-tag is missing
Why is this be a deployment blocker? These messages should really be rare (can happen on pages with some kinds of broken tables in templates). But, in any case, we can suppress these in Parsoid by not sending them to Linter in the first place.
After discussion in #mediawiki-parsoid I'm going to remove this as a deployment blocker since log entries make it seem like this has been happening basically ever since Linter was deployed.

[mediawiki/services/parsoid@master] T168900: Linter: Log error when DSR is missing
@ssastry: The reason it was marked as a deployment blocker is because of the new policy of halting deployments for anything which increases log spam ( Wikimedia-production-error ). Sometimes a log message appears more often after deploying a new branch. Sometimes it's coincidence rather than causation, as may be the case here.
In this instance, the reason it was treated as a bug is because all undefined index notices are considered buggy code as they add noise to the logs: the code should always use isset() before accessing an index that isn't guaranteed to exist.

Parsoid won't be sending lints w/o dsr anymore. Please reopen if that's found not to be the case.
That's great, but Linter should protect against bogus input in a way that doesn't send errors to logstash either.

Ok, see the above.
