When PC freeze, qBittorrent lose config

[TheMadSword]

Hi there,

My computer has currently a non-qBittorrent bug where it sometime freeze (or half-freeze). When such a thing happen, I have to reboot my computer. (It's mechanical, I have it since a while; I think the processor has a messed up register or something; like I can keep moving my mouse but everything else is frozen; and that's not always; and ctrl+alt+delete works rarely; I sometime get my video card drivers to reboot; strange stuff well).

When I relaunch qBittorrent after the freeze+hard reboot, I get the usual message when you first boot qBittorrent (like : "you're responsible for what you do" or something like that). Then I get my full torrent list, but I lose all the columns and columns' length (i.e."Added on" column isn't there by default, I have to ALWAYS re-add it). I also loose all my limit config (i.e. limit DL at 400 ko/s and upload at 50 ko/s, limit 50 max connection, stuff like that).

I'm using 3.1.4 on Windows 7 x64.

I wish the configs would be safe in case I crash (read: hard-reboot) :/. If they would load the same way torrents are loaded I think it would work (thought I didn't look at the code).

Thanks,
TheMadSword

I have a similar problem. Windows crashes due to driver crash and qbt ALWAYS ends up losing its configuration.

This is top priority for me. I am going to make a big overhaul on how settings are managed/saved/loaded from disk. Currently, if I understand correctly the code, it continually opens and reads the settings file and maybe writes to it. This increases the chances of the file being borked during a hard reset.

However this will be marked for v3.1.6 or later. Currently the settings code is all over the place. Overhauling it takes long time. Also for these ~2 weeks I am pretty busy in real life, so I have stopped hacking on qbt. Only patches from others might get approved during this period.

I keep getting burned by this bug, especially when I set my computer to turn off at a specified time while having qbittorrent open. Could you do something simpler than rewriting all settings, such as adding a method on successful shutdown that saves a second copy of the settings file as a backup and an init method that checks for a possible backup? I'm no expert by any means, but I love qbittorrent and would love to help if at all possible. Thanks for providing this program, it's fantastic.

Thank you sledgehammer999.

"- BUGFIX: Third attempt at fixing saving settings on OS shutdown. (sledgehammer999)"

Seems to be in 3.1.5 rather than in 3.1.6 ?

That's another type of fixing that was made before you open this issue. The major code overhual I was talking earlier isn't done yet.

@sledgehammer999 I have a similar problem.
I believe that the problem may lie in the use of INI-format settings.
Now I'm testing my build with using of native-format settings. If you're interested, I can make an appropriate pull-request. You could make a test build and publish it to anyone else tested it.
