FileField.
2023-06-19Refs #34517 -- Restored skipping ImageFileField.update_dimension_fields ↵François Freitag
without width/height fields. This avoids reading the image size when the dimensions fields (image_width, image_height) do not exist, as that operation may be expensive. Partially reverts ea53e7c09f1b8864c20c65976bbeaeab77abdaec, that dropped the check for the dimension fields in update_dimension_fields(), because the post_init signal was no longer registered without dimension fields. However, another code path to that function exists: when the ImageFileField is save()d, the name from the storage is setattr()ed on the field, and ImageFileDescriptor calls update_dimension_fields() because the image size might have changed. Keep bailing out early when dimensions are unused. Besides, computing the image dimensions causes to close() the file, resulting in a backward-incompatible change. The test protects against that change.

width/height fields.

2021-05-13Fixed #32718 -- Relaxed file name validation in FileField.Mariusz Felisiak
- Validate filename returned by FileField.upload_to() not a filename passed to the FileField.generate_filename() (upload_to() may completely ignored passed filename). - Allow relative paths (without dot segments) in the generated filename.

Thanks Florian Apolloner and Markus Holtermann for the discussion and implementation idea. Regression in 0b79eb36915d178aef5c6a7bbce71b1e76d376d3.
2021-05-04Fixed CVE-2021-31542 -- Tightened path & file name sanitation in file uploads.Florian Apolloner
2020-10-12Fixed #32098 -- Made FieldFile use FileField.attname.Sultan
After a93425a37f4defdb31d4ca96bb3bf6da21f0b5ce FileDescriptor is a subclass of DeferredAttribute and uses FileField.attname to access the field data, so that custom subclasses can not only save data to files, but also represent the same data with a different data type by attaching FileFiled.name to a particular descriptor. Follow up to a93425a37f4defdb31d4ca96bb3bf6da21f0b5ce.
