-----------------------------------------
Summary: PGA: handle multiple file uploads that together exceed
post_max_size
Key: AIRAVATA-2326
URL: https://issues.apache.org/jira/browse/AIRAVATA-2326
Project: Airavata
Issue Type: Bug
Reporter: Marcus Christie
Assignee: Marcus Christie
AIRAVATA-1397 added handling for when files are uploaded that exceed
upload_max_filesize. However it's possible for multiple files to not exceed
upload_max_filesize but when combined together do exceed the post_max_size.
Zhong ran into this problem with uploading a couple large files as inputs to
the dREG application.
One problem with post_max_size is that when it is exceed PHP provides only an
empty $_POST variable. So it is pretty hard to gracefully handle when it
happens.
That said, I think there are a couple of things that can be done:
* we can detect when post_max_size is exceed and when it is we can at least
display an error message to the user. Right now they just get dumped to the
home page without any idea that anything went wrong.
* We currently have JavaScript to detect when a file exceeds
upload_max_filesize. We could also add JavaScript to run before form submission
to check to check all of the files, add up their combined file size and compare
with post_max_size
