Jochen Wiedmann commented on FILEUPLOAD-148:
--------------------------------------------
Assuming UTF-32, which is the largest encoding I am aware of, you may set
fileSizeMax to 4* stringSizeMax and have an effective limit. Ok, that's not a
hard limit, because the user might use a more efficient encoding in terms of
space, but that should be fine, IMO.
> FileItemFactory.setMaxStringLength()
> ------------------------------------

> Key: FILEUPLOAD-148
> URL: https://issues.apache.org/jira/browse/FILEUPLOAD-148
> Project: Commons FileUpload
> Issue Type: New Feature
> Affects Versions: 1.2
> Reporter: Stepan Koltsov
>
> Need method
> FileItemFactory.setMaxStringLength(int limitInBytes)
> When this parameter is set, calling of FileItem.getString() when getSize()
> exceeds limitInBytes should throw Exception. This is required to avoid OOME
> in case of wrongly submitted forms (i. e. when bad guy puts big file into the
> form field "fileDescription").
> Or even better sizeThreshold should be used for this value.
