Version 1.7.2 released - Supports Qt5 version of calibre
I have just uploaded version 1.7.2 of the plugin. This has no changes in it except to support the upcoming Qt5 version of calibre. The changes have been made in a way that the plugin can be used with either version of calibre.
Note: I release a beta of the plugin as version 1.201.0. If you installed the beta, you will not be notified of the new version. You can install the released version in the same way you first installed the plugin. |

One possible issue (or not) with your plugin, sideloaded kepubs (through KoboTouchExtended) and covers.
Root issue:
Possible problem with your plugin:
If I want the new cover to be effectively shown I have to follow the next procedure:

I think it has been commented on before that nickle (the main application on the Kobo) caches some items like images in memory.

arspr: Yes, as PeterT said, this is caused by some caching in nickel. Until something happens to clear an image out of the cache, it doesn't get updated. Unfortunately, deleting a book doesn't remove it's cover from the cache.

Thanks guys,
Fully confirmed. Kobo Utilities has nothing to do with it. If I delete the book, I do a turn on/off cycle and I reload the book with the new cover it is perfectly updated... I was looking for the complicated explanation (something weird in Kobo Utilities) and, as always, the solution is the simplest and dumbest one: And yet another bug in Kobo! (Why the hell do you keep in memory anything about something that does not exist? More over when, in fact, you have already decided it is useless because if you perform a turn on/off cycle you do not store it in your permanent memory, database or whatever...) There's an idiom in Spanish, (I suppose in English too), which, literally translated, is more or less: The ways of Lord are inscrutable... And it doesn't only have a religious meaning... EDITED (TWICE)---- What follows is wrong. Period. But if I delete it you won't understand the next post by davidfor and my following one. WTF! This is what also happens with annotations! If you delete your current reading without deleting its annotations and you resend it again those annotations are also cached. But if you perform a turn on/off cycle in the middle they are lost!!! @davidfor, sometime in the past, I pointed out that behaviour, (saving annotations of books that doesn't exist any more, which could be completely modified when you resend them -- in fact I use annotations/highlights in order to mark the typos I find in the books...), as some kind of bug. And you answered me they could be somehow something GOOD, that some people actually preferred that behaviour. Then if you, (Kobo, I mean), have decided they are good, (a decision I do not agree with, but a decision I could understand), WHY do you throw them away with a turn on/off cycle? More over, I suppose the memory of the device is limited, so, how many annotations, covers, whatever, do you "temporally" store? Do you only do this for the current reading?, for the last 3 deletions?, till that "caching memory" (whichever it is) is full?, till when? Then, if the book has not been loaded/opened for a very long time, so the annotations are not in your memory when it is deleted, do you force their loading in order to do this absurd "temporal" storage? Or don't you? Am I the only one seeing a completely absurd incoherency in the design here? Either you store information or you don't, but playing something in the middle with no clear criteria...

The two things are very different.
The cover caching is for performance. The device reads covers from disk and keeps them in a cache for a while. It does this the first time the book is accessed. And as the book is likely to be seen for a while as you read it, putting the cover it in the memory cache makes sense. The cover will be removed from the cache when it hasn't been used for a while and another cover needs to be loaded. I don't know how big the cache is. For the older style home screen, it appeared to hold five covers - enough for the home screen. The cache is cleared when the device is powered off as everything in memory is dropped and restarted. Not removing the cover from the cache when deleting a book is a bug. In general, not a serious bug as deleting and putting a book back on the device with a different cover before the cover is removed from the cache is not expected to be a common action. The bookmarks is different. The device stores bookmarks for epubs in the main memory in two places; the database and an annotations file. The annotations file is created by the RMSDK. ADE creates the same file on the PC. And if you are careful, you can copy the file between the two places. When you delete a book on the device, the bookmarks are deleted from the database, but the file is not deleted. So, if you send a new book to the device with exactly the same file name and path, it will reuse the existing annotations file. As this is a file on the internal SD card, it is not affected by powering the device off. Or at least it wasn't whenever I have tested, including before writing this post. I don't believe there is the same in-memory caching for the annotations as there is for the covers. I can't see any and advantage in having them in memory when the book isn't opened. At the moment, there is no way to clean-up the leftover annotation files. Occasionally, I manually delete them. But, I generally do that because of the bug when reading them messes up the location and percent into chapter. Having this as part of the utilities plugin makes sense. I'll add it to my todo list. |

EDITED---- Tests done with sideloaded kepubs (I'll re-make them with epubs) Sideloaded Kepub.
So, just for a single time, Kobo is doing the things properly. I don't know about databases, cached memory, files on SD, or whatever, but when a book is killed through the device, their annotations are killed. The left-overs, at least with kepubs, happen with external tools (Calibre). So as a summary:
EDITED (2) ------ Now test done with Epubs.
So it really seems that: Deletion of annotations is "buggy" within epubs, (the technical reason being that file leftover from ADE or whatever), but it works fine within kepubs. But, OTOH, Calibre or its driver should be modified to fully mimic the deletion procedure of the device. Last edited by arspr; 08-13-2014 at 02:44 PM.

Suddenly lots of errors in database
After adding a (valid) book in my Kobo Glo I run suddenly in all sorts of problems (freezing) so I deleted the book on the device. Then suddenly all books were unreadable (so the error message said). I run a database check through the KU plugin and there's lots of errors:
Result of running 'PRAGMA integrity_check' on database on the Kobo device: Spoiler:
Also "KOBO EREADER" appeared at the top of the screen (book's title location). I have the 3.8.0 Kobo desktop , 3.3.0 FW (no 3.5.0 yet) and most of my books are on a SD card. How do I solve these problems? Last edited by theducks; 08-14-2014 at 11:03 AM. Reason: Wrapped long paste in Spoiler |

bernard.ryefield: That says the database on the device is corrupt. The only ways to recover are to restore a recent backup of the database or do a logout on the device. With the logout, the device will restart, create a new database and then prompt you to login. It will then process the books on the device back into the database.

I intend to resume this process this time without the SD card inserted, delete all books on the SD card and add back my 4100+ books, a hundred at a time, through Calibre (I run into another problem previously and remember this is sort of a limit). As it will take a lot of time, any more convenient option is welcomed. |
