Overview of merged pull requests
For example when using Fusion in an ajax request, with cache enabled - but no documentNode provided as context, then the calculation of the GlobalCacheIdentifiers fails due to the Eel helper beeing incorrectly used.
This makes the ThumbnailGeneratorStrategy continue with the next available thumbnail generator in case refresh() failed. This allows for a “fallback” to be used in case thumbnail generation fails.
Errors are logged to aid with debugging and if all generators fail another separate error is logged.
See neos/neos-development-collection#3678 for some background info.
The DocumentThumbnailGenerator will now (again) check for Imagick being the configured driver in canRefresh(). If the imagick PHP extension is available and should be used even though Imagick is _not_ the driver for Imagine, a new feature flag can be turned on:
# if set, the DocumentThumbnailGenerator will be used when possible, even if the # used Imagine driver would usually prohibit it’s use (because GD doesn’t do PDF) overrideImagineDriverCheck: true
If reading the source fails without an exception, an exception is raised and passed on from the refresh() method. This e.g. happens when the security policy of ImageMagick denies reading PDF files.
To have ImageMagick deny reading of PDF, as is needed to check this, the policy must be changed to include
<policy domain=”coder” rights=”none” pattern=”PDF” />
the policy is usually in a place like /etc/ImageMagick-6/policy.xml
for Local Beach it’s inside the php container in /opt/flownative/php/build/extensions/imagick/policy.xml. To be able to edit it, you must use docker exec -u root -it yourproject_php /bin/bash to become root inside the container.
