calibre-server quit working

[technochitlin]

When I built a new computer which is running Win10 Creator's Update and the latest version of calibre (2.85.1), my calibre-server script which has been working fine for years no longer works. I have tried starting the server from the calibre program and it doesn't work either.

I have created entries in Windows Firewall for calibre-server, both in-and-outbound.

This is the command I use to start it:
calibre-server –port 8080 –with-library C:\Users\jay-d\OneDrive\Documents\calibre

I'm also getting that error message "Qt: Untested Windows version 10.0 detected!" and if I close that window the process stops.

Anyone have a clue what is happening? I'm pretty sure it was working before the last calibre update but I'm not sure, the updates come so fast...

Don't worry about the Qt: msg re Win 10.

But read this I am getting errors with my calibre library on a networked drive/NAS?

To all intents and purposes, OneDrive, and similar cloud storage services, are a network drive.

Interesting. Moved my calibre library back to my C: drive, and the behavior is exactly the same. Using System Explorer 7 (by Mister Group) as my Task Manager I did notice something else, though- instead of a "calibre-server" process being created after running the command (via a batch file), I have "cmd.exe" in my processes, showing the following parameters-

/c ""C:\My Utilities\calibrelib.bat" "

Note the weird double quotes. This is the batch file I run-

calibre-server –port 8080 –with-library C:\Users\jay-d\Documents\calibre

Strange, to say the least.

Those 'weird double quotes" have been an idiosyncrasy of what one sees in Task Manager/Process Explorer etc for Windows batch/command files since the year dot.

Version 2.85.1 calibre-server is working fine here in using command files similar to yours. I suggest you run a Check Library on the library.

It fails with what error? The message about Qt is not an error, just an information message.

Closing the window associated with a process usually terminates the process under Windows.

After a couple of reboots, moving my library back to the C: Documents\calibre folder, and running a check on the database, it works again. That is great, though I hate it when I'm not sure why something quits working/starts working again. Not complaining though.

In the process of doing this I found an AutoHotkey script that not only hides the process, but hides the Qt error window:

PHP Code:

#NoTrayIcon ; To prevent momentary icon pop-up
run "C:\Program Files\calibre2\calibre-server.exe" –port 8080 –with-library C:\Users\jay-d\Documents\calibre,,hide 


Save that code (modified for yourself of course) as an .ahk script. Works like a champ.

Read the FAQ link I gave you in post #2. It explains why it stopped working. If you keep running OneDrive (a file syncing tool) and the calibre GUI concurrently it will almost certainly stop working again.
