merged branch tomglue/console_reregister_commands_fix (PR #8242)
This PR was submitted for the master branch but it was merged into the 2.2 branch instead (closes #8242). Discussion ---------- [FrameworkBundle] do not re-register commands each time a Console\Application is run | Q | A | ------------- | --- | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | | License | MIT | Doc PR | I have been experimenting with using the Symfony console application inside of a React event loop which works quite well. In this scenario, I re-use an instances of a Console\Application to run multiple tasks. This works well apart from unnecessarily reloading the command classes from all included bundles each time doRun() is called (https://github.com/symfony/symfony/blob/master/src/Symfony/Bundle/FrameworkBundle/Console/Application.php#L68). This can also lead to running out of file descriptors under heavy load as bootstrap.php.cache uses a RecursiveDirectoryIterator to load the command.
