Calibre 3.3 Template Error

[srv181]

With Calibre 3.3 functions like adding books via drag/drop takes about 5 minutes to add 10 books and then leads to a message of "TEMPLATE ERROR maximum recursion depth exceeded".
Same thing when books are converted, and then the original format is deleted.

Apart from this, Calibre functions that change data in the library take overly long, often leading to "non responsive application" errors from windows.

Thanks for your help

Uh! That no happen with a standard (default calibre) template.

You need to post your template so the guru's can dissect it.

thank you, but I have not done anything to the templates (I would not know how

But this morning it took 15 minutes to update a custom field for 2 books - sigh.

thanks

As @theducks said, the default add templates are unlikely to cause this problem. Someone may have done it for you, or, you might have done it inadvertently. The template in question is on the "Adding books" page of the preferences in the "Regular expression" field about halfway down. If you copy and post that, it should help us work out what is wrong.

Also, how exactly do you see the error? Is it an error dialog, or displayed somewhere else? If it is an error dialog, there is probably a "Details" and "Copy" button at the bottom. The "Details" button will usually show more details of the error. This will usually give more idea about where the error is happening and why. The "Copy" will copy the full details to the clipboard. Use that to post the full error so that we can see it.

Sounds to me like a custom column with a bad template

I have not made or changed any templates, mainly because I don't know how to do that.

Meantime I connected a tablet as wireless device, had fairly quick update of metadata, but: since more than 3 hours, the tablet says "waiting for calibre" and calibre on my HP Probook (64bit) under Windows 10 is greyed out and showing no response.

At the same time, this is what my task manager reports (see attached image).

for your information, I have unistalled Calibre, turned off my Bitdefender, Rebooted and reinstalled and this is now still happening.

I appreciate any help and/or ideas,
Thanks
Susanne

Uninstalling does NOT remove configurations or Libraries

Since you made no changes: NOTE, this removes ALL plugins, and user settings for Calibre
open the config folder (Use Preferences:Miscellaneous:Click the bottom button)
LEAVING the folder open in the OS. EXIT CALIBRE
Now, empty the folder (or go up 1 level and remove the calibre folder
Start calibre. It will create a fresh copy of that folder.

Do your test. If it passes, there was a corrupt setting.
If it Fails... report back. Kovid will probably ask for a Calibre Bug report with metadata.db attached

thanks https://www.mobileread.com/forums/member.php?u=42505

I've tried what you said. Originally it enabled Calibre to start fairly quickly, but it did not make any difference in the "no response" problem that still occurs after any change in metadata.

As well, it is just about impossible to synch as wireless with my tab. Yesterday I waited for 3 hours for a synch, only to end up (after reaching 100%) having Calibre give a message that there was an "error communicating with device".

Due to travel, my ability to work on this problem is limited for the next few days, but any ideas are absolutely appreciated.

Thanks again!
