...no, it was just failing on "08:11:01 42 | WARNING | Line exceeds 100 characters; contains 107 characters" and confusingly also included the apc error in the final exception.

Surely annoying but not causing any specific issue.

Seems APC is configured twice in /etc/php/**

This warning impairs readability of the test resutls. Especially things like phplint which have no other output normally and are exclusively run on Zend (and thus trigger this warning for every linted file.)

It's not obvious here that the warnings don't matter, and it's hard to find the one line that actually matters (the PHP Parse error).

integration-slave-precise-1013:/etc/php5$ grep -R "extension=.*apc" .
./conf.d/apc.ini:extension="apc.so"
./conf.d/disable-html_errors.ini:extension="apc.so"
./cli/conf.d/apc.ini:extension="apc.so"
./cli/conf.d/disable-html_errors.ini:extension="apc.so"
./apache2filter/conf.d/apc.ini:extension="apc.so"
./apache2filter/conf.d/disable-html_errors.ini:extension="apc.so"

So it is also enabled via disable-html_errors.ini not idea what it is.

cat /etc/php5/conf.d/disable-html_errors.ini

; This file is managed by puppet
; puppet:///modules/contint/php-disable-html_errors.ini
extension="apc.so"

; Disable html_errors per T97040
; http://php.net/html-errors
html_errors=0

Seems an issue in operations/puppet contint module :-}

Per T97040, this was https://gerrit.wikimedia.org/r/206143. Which was deployed on integration slaves for a short time while debugging. That file was based on another file, and that line was accident kept in duplication.

I've removed the stale files from the integration slaves.
