"Download Only Covers" not working properly

[myle00]

First, thanks for fixing the bug that happened when downloading metadata for multiple files. Also, the download speed is much much faster now. Now to the inevitable bugs...

I opened this bug http://calibre.kovidgoyal.net/ticket/3730 when I was on 0.6.16 and since the command line didn't work for me I couldn't give more details. Now with 17 where the cmd is fixed here are more details. It turns out it was a little more complicated than my first bug report.

Basically when selecting "Download Only Covers" for multiple books it only downloads it for few books. I believe the same thing happens when you click "get metadata and covers" since I have ~8600 books and only ~7700 have covers. But I tried with a selection of only 39 and 51 books to get more details of the problem.

Here is what happens.

First time I run get covers on 39 books I get this

“Exception in thread Thread-55:

In the cmd window and this

In calibre’s window.
Also, only two books out of the 39 received pictures.
Next I find that 9781855739178 matches “Chemical testing of textiles” by “Qinguo Fan”. So I select the 38 books, excluding “Chemical testing of textiles”, and click download covers. Most of the 38 got covers except about 6-8 and it also didn’t give me any massages. Also, only 2 of the books that didn’t get covers were listed in the above book list. So I go through these books that didn’t get covers, individually and download the cover. I find covers for all books except for 2 that were listed above
“Handbook of Hazardous Chemical Properties” and “Sams Teach Yourself Asp.net 2.0 in 24 Hours” So now only 36 don't have covers.


Now I tried it again for 51 books and here is the result.

35 books didn't get covers i.e. no new book got a cover...
This is where I stopped.

It seems I'm the one finding these complicated threading bugs, but I guess someone's got to find it...

Thanks,
