A colleague of mine recently faced difficulties to upload large opensource DVD images (>4G) into ownCloud during a demonstration. After some analysis, it turned out that it wasn’t ownCloud’s fault at all: PHP itself simply could not cope with large file uploads due to an overflow in some key variables. Further research showed that this had been known since 2008 under the bug number #44522. There was even a half completed patch available. I decided to pick up the existing patch and comments from developers and critics and port it to recent PHP, also making some changes to data type definitions. After a discussion on the PHP list, it turned out that this patch cannot be shipped for any upstream PHP before the next release (PHP 5.6) due to backwards compatibility. SUSE Enterprise Linux and openSUSE ship a similar patch with their PHP packages though. Finally, Michael Wallner added tests and included the patch into the PHP master branch.

There only has been very basic testing for Windows and other non-linux PHP ports yet but there is still some time to do this before PHP 5.6 gets released.
