RollbarNotifier class is missing in Monolog handlers folder

[jianzhong]

In monolog/src/Monolog/Handler/RollbarHandler.php, the class is trying to use a non-existing class 'RollbarNotifier' as the first parameter in the constructor. This causes PHP fatal error in my Symfony application. Our Rollbar upgrade failed due to this issue.

I've made a further investigation on the issue. The issue happened when I was trying to upgrade Rollbar from 0.18.2 to a later version by doing composer require ~1.1. The error was something like:

PHP Fatal error: Uncaught Error: Class 'RollbarNotifier' not found in ......

I noticed some changes in the autoload_psr4.php file under vendor\composer folder. The line

'Rollbar\' => array($vendorDir . '/rollbar/rollbar/src'),

becomes

'RollbarNotifier\' => array($vendorDir . '/rollbar/rollbar/src'),

If I changed RollbarNotifier to Rollbar, then I got another error in my Symfony application:

PHP Fatal error: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "RollbarNotifier" from the global namespace.

This is ready for Monolog's team review in the following PR Seldaek/monolog#1042

As soon as the PR is merged to Monolog's master, simple composer update should resolve the issue. Until then I recommend using the changes included in the PR branch.

It doesn't look like our PR for Seldaek:monolog is going to get merged anytime soon. In meantime, I included Rollbar\Monolog\Handler\RollbarHandler in our repo. Please, use rollbar/rollbar-php:master or wait until tag v1.4.1.
