Mivo, the IOSRA plugin does not work wirelessly, you need to have your idevice plugged into a USB port on your laptop, and to be on the safe side, make sure any other idevices are powered off.

Hi,
Hoping someone can tell me what I need to do to fix this one - all was well 2 days ago, now this.
thanks in advance for your assistance!!

DatabaseError: database disk image is malformed

ShellShock · 01-28-2015, 01:45 PM

There are various sqlite databases on your idevice, created by Marvin and (I think) by IOSRA. The IOSRA plugin copies these databases to your PC so that it can interrogate it. The "database disk image is malformed" error occurs when the local copy is corrupt. From your call stack and the plugin code I can see that error should only occur when booklist caching is enabled in the IOSRA plugin. So I suggest you try turning it off: customise the IOSRA plugin in Calibre to turn off "Enable booklist caching on device".

PS: It could be you are short of disk space on your idevice, which I assume is where the cache is stored between sessions.

Nancybny · 01-28-2015, 03:04 PM

I have a ton of room on the iPad, so I did as you suggested with the plugin and restarted Calibre - the first time it didn't work, but then I went into Marvin options and also reset the cache and restarted again... and voila! I really appreciate the assistance!!! Thanks so much

Oh! I should probably have thought of that, thank you.

I guess I'm fairly spoiled by Calibre Companion on Android.

Because you are using an old Calibre, its libimobiledevice is not compatible with IOS 8, so I think you are out of luck, unless you can use the latest version of Calibre (I don't enough about OSX and why you have to use an old Calibre with it).

arrgh. I'm stuck at older OSX (for those who want to know, i need iSync, and that was discontinued starting OSX 10.7.. so I'm stuck at 10.6.8), thus stuck at 1.48.

I guess I'll have to go all manual from now on. grrrr...

it's annoying since the current iOSra says it supports Calibre from 1.37 or so. they need to update that.

ShellShock · 02-01-2015, 07:12 AM

The libimobiledevice library that the plugins use have a "feature" whereby idevices can also be detected via wifi as well as usb. This means that if you have an idevice on your wifi network, it may be detected too as well as the idevice connected via usb that you are trying to get Calibre to talk to. The plugins expect to only find one idevice, and get confused, e.g. the plugins fail to initialise. This is why I have previously advised powering off all idevices apart from the one you are trying to connect Calibre to via USB.

We have now put a small fix into the libimobiledevice code so it will no longer report WIFI detected idevices, so you can keep all your idevices on. You still should only have one connected via USB to your Calibre PC. This fix should be in the next Calibre release.

The plugin is compatible and loads under older versions of calibre. Certain features like supporting new versions of iOS may require more recent versions of calibre.

There should probably be a large visible warning.

micheler · 02-06-2015, 12:34 PM

Hello,
I just updated calibre from 1.48 to 2.18 on an OpenSUSE 13.2 linux system, and the previously fully functional "iOS reader applications" plugin is no more installable (the cited BeautifulSoup module seems to be working if I import it during a normal python session).

Any hints?
Thanks,
Michele

Herebelow is the installation report:

Code:

calibre, version 2.18.0

Try installing the binary distributed version of calibre from http://calibre-ebook.com/download_linux

Often linux distros make odd changes to their calibre builds, calibre officially supports the binary version only. (In fact, I wouldn't recommend using the distro calibre even on Arch Linux, but at least there it is really easy to roll your own.

)

If you can duplicate the problem with the binary, then something is wrong.

micheler · 02-07-2015, 05:42 AM

Thank you, reinstalling as you suggested fixed the problem.
By the way, in order to get the software working properly, I also needed to delete the previous

Code:

~/.config/calibre

folder to avoid problems with claims of missing libraries (Qt4).
Now the system is operational.

Thanks again
Michele

This update did something. at least the iOSRA installs! and managed to install Marvin XD... but even with my iPad connected and set to "add books", connected to my MacBookPro via USB, Calibre won't access the iPad.

but seems like one step closer, as before I couldn't even load the plugin.

akita · 02-08-2015, 02:15 PM

Ok, I managed to install iOSRA into calibre 1.48. I restarted Calibre, and then configured it to access Marvin.

I also installed Marvin XD.

then I restarted Calibre. now every time I restart Calibre when the iPad is connected, I get the error message "Marvin XD require iOS reader installed". and sure enough when I check the plugin list, the IOSRA that I had just installed and configured has disappeared.

so, I unstalled Marvin XD, restart Calibre, re-install iOSRA.

restarted Calibre several times to verify that iOSRA is there.

then I quite Calibre, connected iPad via USB, restarted Calibre, set the iPad to connect to Calibre... and nothing happens. checking the plugin list again and sure enough, the plug in has deleted itself..

what's going on???

ShellShock · 02-08-2015, 04:28 PM

These are all symptoms of the plugin either not detecting any idevices, or detecting more than one idevice. There could be several reasons for this. If you are trying to use Calibre 1.48 with IOS 8 then this is very likely to be the problem - as I explained before, old versions of Calibre do not support IOS 8.
