Create tiny image instead of text when creating a missing blob

mauritsvanrees commented 2 years ago

When using this package in development, I get lots of errors in the log like this:

2021-10-20 11:06:17,168 ERROR   [root:132][waitress-1] could not scale "<plone.namedfile.file.NamedBlobImage object at 0x12775df20 oid 0x26756c in <Connection at 108173610>>" of 'http://localhost:8080/es/front-page'

The site works fine, I see no errors in the browser, but the errors in the log/foreground are annoying. Currently the package sets a string in a missing blob: "File created by experimental.gracefulblobmissing."

Would it be okay to fill the 'fake' blob with a small image instead? I guess just the Plone logo, either in PNG or JPEG. Or maybe just one pixel.

I did something similar in the past: https://github.com/collective/experimental.gracefulblobmissing/tree/auto-create-images

I had a need for this feature and did a rebase on current master on the branch auto-create-images--rebased. PR here: https://github.com/collective/experimental.gracefulblobmissing/pull/6
