PHP agent release notesRSS

March 15, 2012
PHP agent v2.7.5.69

중요

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • Updated to work with Apache 2.4
  • The auto-RUM buffer is now erasable, but doing so will obviously prevent auto-RUM from inserting the RUM header and/or footer.
  • Fixed a problem where WordPress blogs would result in metric explosion due to their database table naming scheme
  • Support transactions that last longer than 35 minutes. Long-running cron jobs will no longer report negative time.

PHP agent v2.7.5.64

중요

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • Support for PHP 5.4RC8 or higher. Please note that versions prior to RC8 will not work correctly, especially not with auto-RUM. Also please heed the advice that the PHP developers themselves give about using the 5.4 release candidates: do not use it in production.
  • Added the frequently-requested newrelic_set_appname() API that will allow you to change the name of the application on the fly. This should be called as early as possible, and cannot be called after the RUM footer has been sent.
  • Fixed an occasional segmentation violation caused by the Slow SQL feature, especially when using the command line version of PHP.
  • Fixed an occasional segmentation violation caused by auto-RUM.
  • Fixed a problem where the ZTS-enabled version of the agent would cause a segmentation violation when used on the command line.
  • Removed the colon from the list of characters that are invalid in SQL table names, and provide a mechanism to disable table name checking completely.
  • Fixed a small (about 10 bytes per request) memory leak.
  • Fixed an issue that would sometimes cause PHP execution time to not show up in the application overview graph.
  • If you call the newrelic_ignore_transaction() API function, no longer produce automatic RUM headers and footers for that transaction.

PHP agent v2.6.5.57

중요

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • Fixed an issue where using file_get_contents() could end up being mis-interpreted as an SQL node and cause a core-dump. This would only happen when Slow-SQL traces were enabled.

PHP agent v2.6.5.55

중요

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • Fixed several issues that would cause Apache to core-dump. Not all users would see these faults, but a few did and those bugs have been fixed.
  • Removed support for the PHP-only MediaWiki memcached client that was added in 2.6.5.41, as the code that was added to support this was part of what was causing random core dumps. It will be re-added in a future release.
  • Use less system stack space when hooking PHP functions so that PHP code that is massively recursive runs less risk of overflowing the stack.
  • Corrected the way the Mac OSX client was being built so it works on OSX 10.5.
  • Fixed a potential buffer over-run error in the Zend and Magento framework code that would be provoked if a controller name was significantly longer than the module name.
  • Removed the backslash from the list of illegal characters in SQL table names as some customers actually use it.
  • Prevent a file descriptor leak if you do a soft restart of Apache.

December 16, 2011
PHP agent v2.6.5.44

중요

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • There is an outstanding issue with the Zend View component where it kills the output buffer that auto-RUM relies on, so for this environment you will need to disable auto-RUM by setting newrelic.browser_monitoring.auto_instrument = 0 and doing manual instrumentation for the time being.
  • Fixed a potential spin-loop that would cause the agent to consume 100% of the CPU if the underlying OS did not allow the daemon connection (even if the daemon was up and running).
  • Only apply Real User Monitoring scripts to HTML content.
  • Fix an issue if auto-RUM encountered content it couldn't parse, it would cause a segmentation violation and cause Apache to core-dump.

PHP agent v2.6.5.41

중요

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • The apt repository is now digitally signed, and in order to update the agent from this repository for Ubuntu or other Debian-like systems you will need to import the new GPG key using the following command (please note the trailing minus sign!):

    wget -O - https://download.newrelic.com/548C16BF.gpg | apt-key add -

  • A very special and big thank you to Nick Calugar of IGN Entertainment for suggesting improvements to the way in which Zend and Magento transactions are named. For these two frameworks the transaction naming is now more accurate and adds less overhead than the previous mechanism used to name transactions. This also fixed an issue where Magento transaction names sometimes had garbage characters in them or sometimes even PHP script fragments. In both cases the transaction is named 'module/controller/action' as it is for other frameworks.

  • Another very special thank you to Roderick Smyth of Arithon in Dublin for absolutely invaluable help during the beta testing period and for testing the OCI8 support.

  • Significant improvements to automatic Real User Monitoring (auto-RUM). The most important change is that auto-RUM is now implemented as an output filter so it now works for all frameworks, not just Drupal and Wordpress. It is also considerably more reliable as a result, as modules and other changes to the framework no longer impact how we insert the RUM header and footer. If you previous had to manually insert RUM headers and footers, you are strongly encouraged to re-enable auto-RUM and comment out your existing manual calls. To go with this change there is a new API call, 'newrelic_disable_autorum()' that you can call to prevent auto-RUM from running for a given transaction. For example you may want to disable auto-RUM for AJAX calls.

  • Regardless of how it is invoked, the RUM footer will now never be ejected if the header was not also ejected in the same transaction. This prevents JavaScript errors if the header somehow fails to get inserted.

  • The RUM header and footer have been very slightly modified to add a missing semicolon after the last script command. This also prevents some browsers and compliance analyzers from complaining about the JavaScript.

  • Support for the MemCache-like features of Redis has been added. This is by no means full support for Redis, just those portions of the Redis API that map cleanly onto the existing MemCache metrics. They will show up in the overview graphs as MemCache activity, so if you use both MemCache and Redis the data will be merged, just as the overview for different SQL databases is merged.

  • Considerably improved support for multi-framework sites (where more than one framework is in use for multiple parts of the same site). Instrumentation for framework-specific functions is now isolated on a per-request basis, so multiple requests handled by one PHP instance will no longer be confused by by the sudden change in framework.

  • The logrotate script no longer conflicts with the version installed by the New Relic Server Monitor.

  • Implemented a timeout for agent-to-daemon communication so that if the daemon becomes unresponsive for whatever reason, the agent will no longer hang (and thus appear to crash Apache) waiting for the daemon to recover.

  • Correctly ignore user notice errors in the error handler.

  • Added support for the deprecated but still frequently used mysql_db_query function.

  • Added support for the Zend framework's Zend_Http_Client::request() method to track external service calls better in Zend.

  • Added the ability to use the syntax newrelic.appname="%{VARIABLE}"when setting the application name. This will use the SAPI's environment variable lookup mechanism to find VARIABLE and set the application name accordingly.

  • The REPLACE SQL command verb will now be recognized and unique metrics generated for it rather than being lumped into "other".

  • A thread mutex deadlock issue on OpenSolaris has been resolved.

  • Support for the pure PHP MemCached client from Wikia has been added.

  • file_get_contents() now shows up in the external services tab if the object being retrieved is remote and uses HTTP or HTTPS.

  • The newrelic_notice_error() now has a third invocation form, which takes a string and an Exception object. If the string is provided it is used as the error message. If it is empty then a default string in a format similar to Exception::__toString() is automatically generated and used as the error message. The exception object provided will be used to create the stack trace for the exception so that you can see the stack trace at the time of the exception, rather than the stack trace at the time of displaying the exception.

  • If you enable the capturing of request parameters by setting newrelic.capture_params = true, you can now also set newrelic.ignored_params to a comma-separated list of sensitive parameters to be excluded from any data sent to New Relic.

  • Support for CakePHP 2.0 has been added, and the CakePHP 1.2 and 1.3 support has been overhauled a little based on feedback from the author, Mark Story. CakePHP 1.2 applications will now be considerably faster when New Relic is enabled due to the new transaction naming mechanism. It will also ensure that transactions are correctly named even if you have implemented your own custom dispatcher class.

  • MongoDB now correctly instruments the update command.

  • Added support for Oracle databases by instrumenting the two most critical calls: oci_parse() and oci_execute(). No other OCI calls are currently instrumented.

  • A bug that had the potential to cause a segmentation violation has been fixed.

  • Several performance improvements that further reduce the overhead of the agent.

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes:

  • New feature: slow SQL. This is very similar to transaction traces but instead records the 10 slowest SQL statements, along with a stack trace of where the SQL was executed from in your program.
  • Fixed a bug in the automatic insertion of RUM headers and footers where they could sometimes be inserted multiple times (especially the footer).
  • The "Drupal Modules" feature can now be enabled and disabled on a per-directory basis like most other configuration settings.
  • A few minor bug fixes that had the potential for causing random agent crashes, although these were very infrequent.
