Out of memory errors

[davidyell]

Full disclosure: This is my first time trying Docker, after seeing your excellent talk at PHPUK19.

I have run two commands and both have written an out of memory exception to the resulting file.

$ docker run -it --rm -v "$PWD":/app -w /app adamculp/php-code-quality:latest php /usr/local/lib/php-code-quality/vendor/bin/phploc -v --names "*.php" --exclude "vendor" . > ./phploc.txt

Results in a file containing

phploc 4.0.1 by Sebastian Bergmann.

When running the phpcpd command the file results in

phpcpd 2.0.4 by Sebastian Bergmann.

Is this related to my locally installed PHP ini settings? Any guidance would be super. Thanks!

It seems to be a php memory limit as you thought.
You can override the limit by passing in -d memory_limit=1G to php.

e.g.
docker run -it --rm -v "$PWD":/app -w /app adamculp/php-code-quality:latest php -d memory_limit=1G /usr/local/lib/php-code-quality/vendor/bin/phploc -v --names "*.php" --exclude "vendor" .

Looking at the Dockerfile, it was set at 512M.

Thanks @hackzilla that's worked for me. I wonder if the commands in the readme should be updated to reflect this.

[adamculp]

Great idea. Also, I'll be updating to use PHP 7.2 to prevent the 7.3 deprecations that affect PHPLoc.

I added a note to the README for future users to know how to handle memory limit errors.
