PHP agent v5.2.0.141

December 15, 2015

On Linux, abstract sockets are now supported for agent to daemon communication. An abstract socket can be created by prefixing the value of the port setting in your newrelic.ini file (e.g. newrelic.daemon.port = "@newrelic-daemon") or newrelic.cfg file (e.g. port = "@newrelic-daemon").
The daemon can now be passed a --define <setting>=<value> flag that allows setting arbitrary parameters from your newrelic.cfg file. These parameters will take precedence over settings from that file.
Drupal 8 requests that are successful full page cache hits for anonymous users (handled by Drupal\page_cache\StackMiddleware\PageCache) are now given the name WebTransaction/Action/page_cache.
Support for automatically naming transactions has been added for Symfony 2.8 and 3.0.
Support for automatically naming transactions has been added for MediaWiki 1.18.0 and newer.

It is now possible to disable reporting of errors for exceptions that are handled by an exception handler installed with set_exception_handler() by enabling the newrelic.error_collector.ignore_user_exception_handler setting.
Calls to newrelic_notice_error with improper parameters will no longer record an error with the message "?". Instead, no error will be recorded. newrelic_notice_error will now return true if an error is saved, null if the arguments are invalid, and false otherwise. If newrelic_notice_error is called with two parameters and the second parameter is not a valid exception, no error will be recorded: The first parameter is now entirely unused.

On Redhat Enterprise Linux 7 and related systems such as CentOS and Fedora, the systemctl start|stop newrelic-daemon commands were not working due to a bug in the newrelic-daemon init script when executed by systemd. This has been fixed.
On some Linux systems, an SELinux policy could prevent the newrelic-daemon from determining the correct hostname. Affected systems were unable to report data because a valid hostname is required by New Relic. This has been fixed. This issue could also prevent the newrelic-daemon from determining the correct hostname when running in a chrooted environment, or any environment in which access to the /proc filesystem is limited.
Detection of Zend Framework 2.5 and later was unreliable when the framework was installed via Composer. This has been fixed.
Detection of Laravel 5.1 and later was unreliable when artisan optimize was used. This has been fixed.
The agent now sends the attribute request.headers.contentLength as an integer rather than a string.
