config option to limit nosy attachments based on size reworking of patch [SF#772323] from Philipp Gortan It tries to avoid reading the file contents just to get the file size but that was too hard for metakit backends. They don't inherit from blobfiles.FileStorage which makes it more challenging. Really that backend should be reworked to inherit from FileStorage. I'm not sure I like the default being sys.maxint. Maybe have 0 == unlimited? But what if someone really wanted to set it to 0 to mean "don't attach anything"?
