Suppress warnings when open_basedir is non-empty

cbj4074 · web-flow · commit 34f136e01b9f · 2018-05-03T12:50:56.000-04:00
If PHP is configured *with a non-empty open_basedir* value that does not permit access to the target location, these calls to is_executable() throw warnings. While Symfony may not raise exceptions for warnings in production environments, other frameworks (such as Laravel) do, in which case any of these checks causes a show-stopping 500 error. We fixed a similar issue in the ExecutableFinder class via #16182 . This has always been an issue, but 709e15e7a37cb7ed6199548dc70dc33168e6cb2d made it more likely that a warning is triggered.
