Remove Author by regex gives errors

[drMerry]

I wanted to remove authors by using the regex replace .* with ""

I selected 114 books I wanted to apply this tweak on.

I got errors the author field can not be empty

calibre, version 0.8.9
ERROR: Zoeken/vervangen ongeldig: Het auteur-veld mag niet leeg zijn. Boek met titel The Ambassadors From Aurigel niet verwerkt

I do get this error for every book because there is no abort function.

Work-around: hold escape key, this will cause the update-process to catch it (by accident) so the complete process will quit

What is the bug? A book cannot have an empty author.

[drMerry (invullen)]

The problem is that I used this function on 114 books.
I will get 114 times the message that a book can not have an empty author, without a button to abort the replace.

Because I held the esc I could quit the process but if someone does not use the esc to quit a screen or does not hold it for a longer time, they will get 114 error messages.

OK, you are looking for an enhancement: add a cancel button to that error dialog that cancels the S/R. Changing to wishlist.

Note that a cancel button will not cancel any that might successfully have been done before the error, and it will not cancel any other operations on the other two tabs.

[drMerry (invullen)]

The function I'm looking for is something like:
"Abort further processing".

So it is something like cancel, but it should stop all further processing, also on other tabs.

[Charles Haley (cbhaley)]

Assuming I add the button (not yet decided), it will stop the search replace. It will not stop any other processing nor undo any processing that has already been done.

[drMerry (invullen)]

undo is not what I was thinking about, but I think a complete stop would be a good idea. What if edits are based on the search-replace result (to be)?

[Charles Haley (cbhaley)]

The error messages have been removed. Changing authors or title to an empty value now fills it in with calibre's default value for an empty book.

A good fix for this use-case I think.
Thank you.
