Ooo! Sort by cover brought up fron 2 books that needed a quick 'Generate Cover'

Divingduck · 08-13-2013, 03:03 AM

Hi Kovid,

thanks’ for the fix from post 206.

I found another one (sorry) on the new sort criteria series_sort and formats:

Spoiler:

Another point I saw was the new setup-dialog of cover grid. I am very pleased to see that you integrate a variable aspect ratio based of dimensions what I can setup now in x/y fields. To come back in the automatic setup I need to make a lot of clicks if I choose a bigger cover view. It is maybe a good idea to put in the tool-tip description a hint, that setting a value of 0 in the x/y field has the same effect.

Again, thanks for this very nice feature

That was the full error message there is no "Show Details" button (see attached). This happens on both the old and new backends. With and without a virtual library enabled.

My stats:
Windows 7 64bit
Calibre 0.9.43.0 Portable (32 bit)
Virtual Library

Update: It even happens on older versions so this must be on my system somewhere. A new install in a new location puts it back right. I guess it is time to figure out what file in calibre settings was corrupt, any ideas?

@DoctorOhh: Try running in debug mode (right click preferences button), that might give us more info.

kovidgoyal · 08-13-2013, 03:44 AM

@Divingduck: series_sort and formats should not have been included in that menu, I will fix that. I will add a note about zero to the tooltips.

I went back to a backup from 10 days ago, same problem. Here is the debug log after opening calibre then trying to get the cover and metadata from the book. I don't see anything useful.

Spoiler:

I'm curious what the fanfictiondownloader line is about I don't even have it installed.

kovidgoyal · 08-13-2013, 04:21 AM

Try setting the cover instead of getting the metadata, that should have details on the error message. I've added the code to get error details when reading metadata fails as well, but you will have to wait for the next build for that.

The fan fiction line implies you do have the plugin (or some other plugin that uses that file) installed, it doesn't come from calibre itself.

What do you mean "setting the cover." The cover and metadata get added to books fine it is only when I try to set the cover or metadata via the icons to get it from inside the book do I get the error.

Since I rarely use this feature I have no idea when it stopped working.

I'll leave my setup alone and see what errors the next build might show.

I may have installed and uninstalled it many moons back. Maybe JimmXinu has the code copied to one of his other plugins that I do have installed.

Use the set cover button the one with the brown book on it instead of the set metadata button, the one with the blue i on it.

That is where I first saw the error. Same error for either button.

kovidgoyal · 08-13-2013, 04:57 AM

Yeah but the get cover error message will have a show details button.

Not on my system, they both have they exact same error I attached previously.

OK, then you will have to wait till the next build.

No problem.

If I must have this feature all I have to do is open a new install and point to my current library. Of course that means redoing all or most of my plugins, customizations, and tweaks.

The new disk cache for the grid view works very good. Very fast once the covers has been cached. Also a very nice touch to allow the user to open the cache folder and clear it.

I have found that virtual libraries together with the grid view is like a marriage made in heaven. Like switching between book shelves, only better. I am in the process of adding more virtual libraries...

I use Ubuntu 13.04 and I successfully moved the cache from my home directory, on a relatively slow mechanical HD, to SSD. I actually moved all the caches in ~ from the HD to the SSD, by adding the line...

Code:

XDG_CACHE_HOME=/opt/SpeedUpFolder/adoby/.cache

...to the the file ~/.pam_environment.

Works fine, and I feel that is a very good use of my SSD. I already have my metadata.db:s in the SpeedUpFolder.

Four minor suggestions that doesn't really change anything, mostly just to give calibre a little more "polished" feel and make it a little easier to use:

1. It would be nice if, when connected to a device, there was some hint that a book is present on the device. In the normal record view the "On Device" column can be used. In the grid view there could perhaps be a 1px lighter frame drawn around books that are on the device, or a slightly lighter background?

2. When the disk cache for the covers has been made invalid, after a change of cover sizes or the cache emptied, the grid view is slow because the images has to be cached again. It would be nice if the cache could be rebuilt automatically, perhaps by a low priority background job. Similar to the one that generates the backup OPF-files. Perhaps activated with a check box in preferences.

An alternative could be to precache the books adjacent to the current view. A page or two worth of books up and down, from the current view. Could perhaps be used to refresh the memory cache from the disk cache, and if it fails instead update the disk cache.

3. The +/- buttons in preferences to resize the cover while preserving aspect are very nice. When you get down to 0 size "automatic" returns, but it took me a little testing to discover that. It could be helpful with an extra button automatic/default or reset between the +/- buttons.

4. The cover grid was especially nice to use when used together with several virtual libraries. It makes it possible to very quickly change the grid to show a smaller subset of books. A tabbed interface to the grid view could enhance this a lot. Perhaps tabs at the top of the grid, that always are visible and possible to scroll left and right. And optionally to remove. To switch virtual library, just cklick on a tab.

Perhaps a checkbox when editing the virtual library: Show as tab in cover grid.

And the first tab "All" to disable virtual libraries.
