[GUI Plugin] Kobo Utilities - Page 9

This is probably a rather unusual edge case.

Kovid has added the ability to calibre to allow the Connect to Folder operation (found in the Connect/Share menu) to also specify a device type for the connection. This is extremely useful in my case where my main conputer right now is a ChromeBook. While yes, calibre does run in the ChromeOS linux development environent (crostini / penguin), one drawback is USB support/removable device support is limited inb that all that can be done is to share the device's file system with the Linux environment. All shared devices are then accesible via the /mnt/chromeos mount point on the Linux side; the device is NOT seen as a USB device; rather the mount is via 9p file system.

Testing has shown that the 9p file system does not support some of the I/O operations required by sqlite (used by Kobo to access the KoboReader.sqlite database). These I/O operations are required due to the database having Write Ahead Logging enabled (WAL).

I found though that if I simply cloned the Kobo storage to local storage and had calibre open the local copy all worked (including Kobo Utiities plugins).

The fun however occurs when I point calibre to the /mnt/chromeos/removable/KOBOeReader directory. Kovid has implemented a workaround for the file system issues by copying the Kobo database to local storage, letting calibre access that copy and then on disconnect, copying the database back to the Kobo. Changes for this copying can be found in recent changes to the Kobo driver (look in both devices/kobo/driver.py and the new devices/kobo/db.by modules).

In this case, while some of the Kobo Utilities functions DO function, both the Check the device database and Compress the device database functions fail; probably due to the plugin obtaining the location of the true database (i.e. /mnt/chromeos/removable/KOBOeReader/.kobo/KoboReader.sqlite and not the copy that the driver has created.

This testing has been performed using preview release 7.26.102 and the current GitHub source.

You can find the discussions leading up to this change in the following thread Wish for Device Driver mount point

Well, the Chromebook is the best value "netbook" / small laptop running Linux, so it may become more popular. Might be outselling Windows & mac laptops in USA non-corporate now.

So important "edge case".

Yes, I said an editable list of things to back up would be nice.

Thanks for letting me know, and for testing the current functionality. If it's just those two operations that are failing then it probably shouldn't be too difficult to make it work on Chromebooks. I've created https://github.com/majutsushi/kobo-utilities/issues/10 to track this, although since I don't have a Chromebook myself I can only do limited testing.

I'm about to create a new release with a few changes and a bunch of internal improvements.

The user-visible changes are:

Removed support for modifying home tiles as it is not supported in current firmware versions
Fixed an issue that prevented device rename and delete buttons from being enabled when only one device was registered

Due to the various internal changes it would be great if a few people could test out this build to make sure I didn't break anything. Most of the changes are benign but you never know what kind of edge cases I might have missed in my own testing. Thanks!

Majutsushi · 03-10-2025, 05:04 AM

Hmm, looking at the recent Calibre changes I may have to make some changes anyway to keep the plugin working. I'll do some testing.

I have not noticed anything breaking on preview 103, but I don't use every feature.

Odd, according to the commit the database connection methods have changed, and so no feature that tries to access the device database should work, unless I'm missing something (which is possible since it's quite late). It also looks like the replacement is only available in the KOBOTOUCH class, not the base KOBO one that is used for the ancient original devices. I'll look into it in the next few days.

Edit: I just realized why it still works, the plugin creates its own connection if it can't get the one from the Calibre driver. So it would probably make sense to use the new functionality when available and leave the fallback in place. That may also fix the Chromebook issue above.

Majutsushi · 03-10-2025, 06:11 AM

Okay, it looks like I can't just use the new DB functionality since it's inherently tied to transactions, which means using it would result in the same vacuuming error that I fixed recently. So for now I would have to create a plugin-specific connection for normal operations (what the current fallback is doing) and probably duplicate the copying behaviour for the cases that are failing on Chromebooks.

Running from current source seems to work. Unless I misunderstoood?

Yeah, it currently works because the plugin falls back to its own connection. I meant that if I wanted to make use of the new DB methods then it wouldn't work any more for this case.

Majutsushi · 03-10-2025, 07:09 AM

Looking at how the new DB functionality works by copying data between the device database and a temporary one (using Connection.backup()), I'm not sure the two failing database operations make sense to run on the temporary database. Vacuuming the temporary database should have no effect on the original database since it's not part of the data that would be copied, and similarly with the database checking. So the best thing I can probably do is catch the error and present a friendlier error message.

Edit: Vacuuming may not even be necessary in this situation anyway since the data copying may have a similar effect by its very nature.

Just ordered my first dedicated ereader. I chose the kobo clara BW. I know this is a newer model. Will it work with this plugin?

Yes, the Clara BW will work with Kobo Utilities.

DNSB · 03-13-2025, 04:13 AM

I've run into an issue when ejecting a Kobo ereader either using the Smart Eject plugin or using the Eject this device option on the Device menu. calibre version is 7.26.103 running from latest source on Windows 11, Kobo Utilities version is 2.18.4 (the test version). I also—if I did the steps properly—have reported the issue on the calibre bug tracker.

Error message is:

Spoiler:

Edit: report on calibre bug tracker rejected as third party plugin issue.

Edit 2: Went to change the customization and got an error. Found a block of garbage at the end of the KoboUtilities.json file so renamed and rebuilt. Worked once and then back to the error when ejecting. The .json file still looked okay.
