High CPU usage when "saved searches" dialogue is opened

Ahmad Samir · 04-28-2014, 02:46 AM

Hello.

When I open the "saved searches" dialogue in ebook-edit it suddenly starts using around 60-90% of one of my CPU cores. Closing the dialogue and the CPU usage goes back to normal.

This happens when there's a book open or not; there are currently no entries in the dialogue but the same issue happens if I add one or two entries.

This is with:
- calibre-1.33 and 1.34
- qt-4.8.6
- PyQt4-4.10.2

Does anyone else see this issue?

Edit: I forgot to say that I am using Linux.

in Windows 7, calibre 1.34 64 bit hi CPU usage shows up in a calibre-parallel process, if I run it from portable it shows up in the ebook-edit process itself.

That was fast; thanks. I applied that commit when building calibre-1.34 and the bug has gone away.

I like Sigil but letting HTML Tidy loose on a document and letting it auto clean/correct it is a menace. HTML Tidy is a great tool, to be run manually (i.e. you see the log on stderr) on an (X)HTML file to spot any errors in the HTML code, but not so good when it comes to correcting those (if any) errors, that should be done manually too, except for the most basic errors.

Congratulations on such a great tool. I've often mused that it would be great to have an EPUB editor that just leaves the HTML code alone (like any regular text editor would do) unless told otherwise, and there is it in Calibre; an it comes packed with a lot of useful features/tools. :-)
