Directories can also match the glob search pattern if their names end in ".php", which will cause a read error later since the ContentRetriever implementers are expecting files. This behavior can be reproduced by installing the Composer package "mtdowling/jmespath.php".

As far as I know, the only way to fix this is to do an additional check to ensure the URI is not of a directory.

This resolves #306.

Upon further inspection, it seems that the workspace should never contain a directory, so it should be safe.

Accepting as a fix, but an additional stat on every file is not the best. Maybe the implementation should be changed to not rely on globs anymore...

I agree. For what it's worth, I tested on a codebase of ~3500 PHP files and the performance (in seconds) was the same as it was without the is_dir check.

Maybe it should utilize the symfony finder which is also capable of using native commands to speedup the process

What does it provide over RecursiveDirectoryIterator for our use case?

we need to benchmark whether the "native finders" are faster/more effiecient or not.

or was your question related to features the sfFinder can provide?

maybe a non-glob (php native) finder would be enough though

What are "native finders"? RecursiveDirectoryIterator is native too

symfony uses system/exec to use the OS capabilities

I couldn't find that in Symfony's codebase, could you give a code pointer?

hmm it seems this feature was deprecated and removed later on
