> Key: ZETACOMP-70
> URL: https://issues.apache.org/jira/browse/ZETACOMP-70
> Project: Zeta Components
> Issue Type: Bug
> Components: Webdav
> Reporter: Jérôme Renard

> The Problem:
> On my work with the Webdav component i figured out that every php script
> using with component crashs with file uploads larger than 1GB. After some
> server tweaking it was clear that there must be a reason in the component
> code.
> I traced the code and found a line like this " $properties['body'] = $body
> ".
> Then it was clear. A string with 1GB was copied into an array and crashes the
> php module with this operation.
> The workaround:
> To avoid large memory usage I went over to use the php tempory storage. So
> the maximum amout of used ram is at my configuration 2MB and the rest is
> streamed to disk. To make working with it easier I wrote a wrapper clase and
> placed it on every part that is reading or writeing the document body.
> Luckily this is only neccessary at Webdav/src/transport.php and all of my own
> files.
> As the wrapper could also be used with other components its located at Base.
> Note :
