TYPO3 peak memory
=================

This extension adds a HTTP middleware to the TYPO3 frontend and backend
stack that sets the HTTP header ``X-TYPO3-PHP-peak-memory`` with the
result of PHP ``memory_get_peak_usage()`` in bytes.

This extension is an easy way to get an idea which requests may be
memory hungry, and if changes to the codebase affect memory consumption.

The middleware is positioned very early (or late, depending on how you
look at it) to catch the majority of the TYPO3 request processing.

The header is added in backend requests, if
``$GLOBALS['TYPO3_CONF_VARS']['BE']['debug']`` is configured to
``true``, and in frontend, if
``$GLOBALS['TYPO3_CONF_VARS']['FE']['debug']`` is configured to
``true``.

Installation
============

Composer
--------

You probably want to install this as ``--dev`` dependency. The extension
currently supports TYPO3 v11 and TYPO3 v12:

::

   $ composer require --dev lolli/peak-memory

TYPO3 Extension Repository
--------------------------

Extension key is registered, but the extension is currently not released
to TER.

Usage
=====

When debug mode and stuff is on, all HTTP requests that go through TYPO3
add the HTTP header. Use browser inspectors or something to see them.

Tagging and releasing
=====================

`packagist.org <https://packagist.org/packages/lolli/peak-memory>`__ is
enabled via the casual github hook.
