* Don't double file extension in clean_filename * Don't use display_name as ClearableBasenameFileInput.FakeFile.name Reason: it's used as the thumbnail source and therefore needs to be a valid file name and not some display name

def clean_filename(fname):

hierarkey.forms.SettingsForm appends a random value to every filename. However, it keeps the
|
|
extension around "twice". This leads to:
|
|
|
|
"Terms.pdf" → "Terms.pdf.OybgvyAH.pdf"
|
|
|
|
In pretix Hosted, our storage layer also adds a hash of the file to the filename, so we have
|
|
|
|
"Terms.pdf" → "Terms.pdf.OybgvyAH.22c0583727d5bc.pdf"
|
|
|
|
This function reverses this operation (leaving names without doubled extension as-is):
|
|
|
|
"Terms.pdf.OybgvyAH.22c0583727d5bc.pdf" → "Terms.pdf"
|
|
"Terms.pdf" → "Terms.pdf"
