[jira] [Commented] (GUACAMOLE-44) Upload/download of files that are more than 1 GB fail

["Michael Jumper (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GUACAMOLE-44?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15311595#comment-15311595 ] 

Michael Jumper commented on GUACAMOLE-44:
-----------------------------------------

Download via SFTP or RDPDR is working perfectly with the new changes. Printing, however, is not. The RDP printing code begins streaming immediately, not waiting for an "ack" from the client.

This means the GET request to the stream endpoint will likely occur *after* data has already been sent, resulting in data being dropped. If the GET request occurs after the stream has closed, then it will block until some other stream with that index is opened, leading to mismatches in the downloaded results.

> From Chrome, after attempting upload of a file greater than 1 GB in size:
> {code:none}
> Uncaught TypeError: Cannot read property 'length' of null client-ui.js:1525
> _upload_file.reader.onloadend
> {code}
> Uploading this file via Firefox simply crashes the browser. The same issue will occur for file downloads, as Guacamole always creates the entire file in memory before starting the transfer.
