Make file upload logic configurable
-----------------------------------
Key: SLING-2166
URL: https://issues.apache.org/jira/browse/SLING-2166
Project: Sling
Issue Type: Improvement
Components: Engine
Reporter: Chetan Mehrotra
Priority: Minor
The current file upload logic in Sling Engine (as present in ParameterSupport
[1] class) relies on Common Fileupload. This logic can be enhanced to use some
features provided by the Common Fileupload library
- Allow location of folder where temporary files are created configurable. This
can be done by specifying the repository in the DiskFileItemFactory. So for
Sling we can set to a folder under launchpad and better manage it
- Enable the FileCleaningTracker such that any temporary file that gets created
also get deleted.
- Allow specifying the maximum file size that can be uploaded
- Update the version of file upload library
Further the FileCleaningTracker can be exposed as a service and used by other
components
