New database backend - testers needed

Sure.

I have one issue left with the new backend: adding books sometimes modifies metadata of completely unrelated books, and lots of them (I've seen the Backup Status go from 0 to 3000+ out of 74K after adding some 70 books).

I've tried to figure out whet exactly triggers it, but I haven't been successful yet. Disabling Alfs' tools didn't make a difference. Are there other things I could try to get to the bottom of this?

Generally that will happen if the case of some tag or author or series changes. i.e. if the newly added book has an existing tag, but with different case.

Hmmm....yeah, that might be it, but shouldn't that have happened with the old backend too, then? I've never seen it before, and now it happens almost very time I add some books.

I'll try importing to a scratch library and zapping the tags there to see if it stops doing it.

Hi,
I know this is off-topic, but how do I get my calibre library to look the one in the thumbnail? My library just shows rows of books, not like the covers shown in the first post.

Thanks in advance.

You have to have enabled the new database handler. After having done so when you restart Calibre there is a new icon on the bottom right to enable that view.

To respond to my own post: nope, it doesn't. I added 70 books to an empty library, cleaned up the metadata and removed all tags before moving them to my main library.

That resulted in almost 1100 changed records. I'll wait for the next version to see whether that helps

#2and #4 working great running on Ubuntu 12.04.
#1 looks good on default cover size, not so good on smaller sizes.

The performance of the cover grid is now ready for Prime Time.

When I select a book and open the edit metadata window I can not set the cover or the metadata from any book format using the cover or I icons to the left of the formats area. I get the following error:

calibre, version 0.9.43
ERROR: Could not read metadata: Could not read metadata from epub format

I get an equivalent error if I try to use mobi or azw3.

All that, and the Sort working too - what does Sort on Cover do?

There are also changes to the Book information window (press 'I' on a book). The Book Cover Grid and List will now track the Next & Previous buttons, there's a splitter to adjust the relative widths of the cover and metadata areas, and the Title has been moved to the Top of the metadata area.

And the image caching scheme is PDQ

Thanks - all working on a 25000 book library on Win 7 64bit

@BR: Sorts by the has_cover field, i.e. books that have or not covers.

@DoctorOhh: Works for me, can you post the full error message (Click Show details)
