Stale file contents in redirected drive

[fiddyschmitt]

Hi,

Environment

Windows Client (mstsc) connecting to Ubuntu 22.04.5 (xrdp 0.9.17).

To reproduce

I have shared a drive from Windows, and its content appear fine in thinclient_drives

1. On Linux open a terminal and run: tail -f hello.txt
2. On Windows, add a line to hello.txt
3. On Linux open another terminal and run cat hello.txt

Expected results

• The tail command in Linux displays the added line
• The cat command shows the added line

Actual result

• Neither the tail or cat commands show the new line

Only if tail is closed will cat see the new data. It seems that if the file is open for reading, its latest contents don't propagate from the client to the server.

Thanks for this, @fiddyschmitt

An option to address the particular issue you raise was added by @bobcarroll in #3255

To use it, you'll need version v0.10.2 of xrdp or later.
