This improves, for example, the exception one would receive if they tried to import a resource from a bundle that doesn't exist.
Previously, the deep "bundle is not activated" exception would be thrown. That has value, however there is no indication of where
the exception is actually occurring.
In this new implementation, we throw an exception that explains exactly which resource, and from which source resource, cannot be
loaded. The deeper exception is still thrown as a nested exception.
Two caveats:
* The `HttpKernel::varToString` method was replicated
* This introduces a new `Exception` class, which allows us to prevent lot's of exceptions from nesting into each other in the case
that some deeply imported resource cannot be imported (each upstream import that fails doesn't add its own exception).
* subsven/master:
re-add filename based directory filter to the AnnotationDirectoryLoader, now restricting to *.php files and therefore disregarding e.g. SVN metadata files
revert adding filename based filter to the directory resource
Eleminate the need to manually clear the cache if a new controller file containing routing annotations is added - part II * add unit tests * introduce filename filter to DirectoryResource (to restrict change monitoring to a subset of files) * modify AnnotationDirectoryLoader.php to use filename filter set on Controller\.php$
* add unit tests
* introduce filename filter to DirectoryResource (to restrict change monitoring to a subset of files)
* modify AnnotationDirectoryLoader.php to use filename filter set on Controller\.php$
Changes on the Router to avoid array_diff, array_keys and other inneficient array_ functions.
This is a "recommit" to respect Symfony Contribution rules
* fixes a problem with security (/foo/bar and /foo///bar are not the same URL as far as security is concerned)
* this can still be done in your web server configuration or by adding a core.request listener
in your routing configuration, only existing files in this directory
get tracked for changes in this directory. So if you add a new
controller file in this directory you'd have to manually clear the
cache since the new file gets ignored.
This patch adds a DirectoryResource for this case which tracks all
changes in the given directory (and files and directories contained
within).
In routing files, import statements allow an optional "type" option to hint the resources' type (e.g. for ambiguous file extensions). This adds the same type option to the FrameworkExtension config, which defines the main routing resource.
