iOS Calibre Companion error wiping the app empty.
I've been using Calibre Companion on my iPhone, it's on my iPad as well. I use it to keep metadata via txt files. I had over 4900 files in the app.
Today I've been trying to update it with an extra 32 files, instead of adding the new files the app disconnected and removed all files in the app. I tried to load them all again in tranches of 1000 at a time. It was working until the end of the third tranch when that disconnected and again wiped the app empty. Any idea what's going on? I was able to update my ipad app without any problems. |

Actually my iPad app is empty too now. Both apps have nothing.

It sounds like you ran into the same problem reported in this thread. If so then CC V1.1.1 released a day or 2 ago should fix it. Have you received that new version from Apple?

As Chaley wrote, this is a bug I've been trying to fix for a while. More detail in that other thread. As for the update, it takes a few days for Apple to approve them. I submitted it end of last week but it didn't get approved until the end of the weekend. By the timestamp on your post, it seems like you checked only a couple of hours before it got approved.

I don't mind the crashing tbh if only the app wouldn't wipe itself clean when it does. |

The other thing that will help is to fully close the app (double tap home button then swipe it away) after transferring each 1000 books. The app performs some maintenance on the database at start-up which will help; this only takes a few seconds to do.
There are two problems happening at the same time: (1) the app used to run out of RAM during book transfers. For me, when transferring 1000 books, the app used to use about 120mb and now it only uses about 50mb. This problem manifested itself by the app abruptly crashing (returning to the home screen of the iPad without notice) during book transfers. This really should happen a lot less now. (2) the database file itself could get too large. This one hasn't been fixed quite as nicely, since it requires the app to be restarted, as mentioned above. However, it should still help; for me, my database file reached approximately 800mb after transferring 1000 books, and then after restarting, the new maintenance code reduced it down to 50mb. Different devices have different limits, but it seems that if the app is launched with a database of between 2 and 4gb, the database corrupts and gets reset. So it's a bit of a pain, but as long as you restart the app between sending batches of 1000 books, you should be able to get further. (And yes, figuring out a better way of handling this is still on my list!) Last edited by Steve_Haley; 02-13-2017 at 01:19 PM. Reason: Added much more info |

Steve_Haley, using your advice about closing the app after each tranch of files added along with my husbands W10 Pc, which is an I7 with 12GB Ram, and Calibre 64Bit I got all my 4900 TXT files loaded on both my iPad and my iPhone. Hopefully I can just add new txt files as I buy new books now.
The memory issues maybe why the iOS app has only ever worked on my husbands laptop as it's the most powerful laptop we have, my MAC only has 8GB and our W7 laptops even less. Plus the W7 laptops don't have Calibre 64Bit. Thanks again for the advice ![]() |

Good that it is working, and also good that you added confirmation to one of Steven's theories about what must be happening. ![]() |
