Mike Jumper commented on GUACAMOLE-1276:
----------------------------------------
[~qq296015668], none of this will have anything to do with MySQL, but thanks
for the details.
It looks like changes from GUACAMOLE-764 were accidentally partially reverted
during conflict resolution for GUACAMOLE-249. File uploads previously
(incorrectly) used 32-bit offsets, resulting in file truncation at ~4 GB. This
was supposed to have been corrected with GUACAMOLE-764:
https://github.com/apache/guacamole-server/pull/223/files#diff-f5fd7fdc2c1331b32ab1899613971f13dd00be3e048e3dcdaeddc584e3d91b23R60
But that switch from {{int}} to {{uint64_t}} was effectively undone via
GUACAMOLE-249:
https://github.com/mike-jumper/guacamole-server/blob/53f981f864475763f64d608ca1dfea7c7e094472/src/protocols/rdp/upload.h#L36-L40
> The upload file size in the rdp protocol exceeds 4GB and cannot be uploaded
> successfully
