PyRDP hangs when downloading a file of 108 bytes on the client's shared drive
Weird enough, the player hangs when trying to download a file of 108 bytes. Tested with a Windows 10 client. I can add more detail if needed, but I don't really know what would help with this issue.
The maximum "payload" size that the client can send is 2^14, so 16384. I scripted the creation of these files, and tried to download them all.
The only one that hanged was 108 bytes, and every other N * 2^14 + 108.
This is still reproducible. There's a lot of noise on the device redirection channel, so it's very hard to track what is happening to compare working transfers with non-working transfers. We'll need to add some debug code to help investigate this.
So far I compared two files (one working, one not) and I noticed that the transfer hangs on/after an IORequest from the client to MJ_READ the file descriptor. The working file doesn't have a single READ call, so I'm thinking this might be related, but will need to find time to dig deeper...
NOTE: While we instrument this, we should address #222 since it's located in the same code area, and maybe shed some light on this.
