The user template functions is not working for me no matter what I do. I can create one, see it in the database, but, when I restart calibre it does not appear. This happens whether I run from source, or use the installed beta. And, it doesn't matter how I create the library. I have tried creating a new library copying my existing structure and creating a new library with the default configuration.
The attached database and JSON file come from using the installed calibre 5.99.12 by clicking on icon created when installing. I uses "Switch/create library" and created a new directory. After that, I closed calibre. Then I opened it and created a user function template using the example in the help, except that I added a couple of a's to the name to have it first. Then I closed and reopened calibre. When I looked, the function was not their. I then zipped up the database and backup file.
For simplicity, I created the same directory structure as you. That was to make sure that the paths in the config files did not not need to be fiddled with. And of course, it worked:
And running using my normal configuration it doesn't work. Looking through the log below, I can see "backend.__init__" called twice, but, only once in yours. The position in the log suggests that a plugin is triggering that.

And the problem is in the plugin Clean Comments. That has:
Code:
def build_menus(self):
m = self.menu
m.clear()
candidate = self.gui.library_path
db = LibraryDatabase (candidate)
I don't know why it is doing that as it doesn't actually use the database in that, or the other method. Where it does use the database, it connects to it properly.
Removing the last two lines, plus the similar ones elsewhere, fixes the problem.
And I have posted a fixed version in the plugins thread.
I see what is happening. When you open a database it registers its user-defined formatter functions using the library UUID. When a database instance is closed it de-registers them using that UUID. This means that if you open the *same* database twice then the functions are registered using the same UUID, which in practice means they are registered once. When either is closed the functions for both are deregistered because they share the UUID.
You can see this happening in your log:
Code:
backend.close - unloading template functions 32d3fa1c-9a4a-450a-a422-e0dcface23d5
[7.64] main UI initialized...
The problem can be avoided by passing is_second_db=True when opening the database.
I looked at checking for a second registration of functions for a given database. That won't work because it is legal to re-register functions for an open db instance, for example when functions are created/changed in preferences / template functions.
