Provides an interface for classes to implement their own flush()
functionality. This function gets called early in a request on
all implementations of Flushable when flush=1|all is requested in the
URL.
This fix came out of an issue where Requirements combined files were not
being cleaned up after dev/build?flush=1, due to the fact that flush
would only occur when you called it while on a page that used those
combined files, but not in any other contexts. This will now call flush
on any implementors of Flushable regardless of the context of where
flush was called.
This change fixes an issue where old/existing formatted images are used
when a filename is reused (by overwrite or by coincidence), regardless
of if the file contents have changed. To users this mainly manifests
as a file overwrite appearing not to work; the thumbnails in the CMS
show the original image until regeneration is forced.
Calling Image::deleteFormattedImages() after image upload ensures that
no stagnant formatted images will be used.
If multiple image manipulations are performend the resulting cached image is stored in assets/_resampled because the cached version of the image has no ParentID, which cacheFilename needs to set the correct path.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
Because some extensions add functions that generate cached images, deleteFormattedImages()
needs to find all the method names by passing true to allMethodNames().
Apply preg_quote to each generator name and to $this->Name so that their use in a
regular expression will not cause run-time errors.
Provided fixture and test.
ENHANCEMENT New FileNameFilter class for a more customisable way to influence filename filtering in Upload->load(), Folder->addUploadToFolder() or Image->loadUploadedImage()
