[Deluge] #3322: All torrents disappear occasionally after restart

Hi!
I have about 150 seeding torrents, and sometimes it happens that all of my
torrents disappear without any reason(accidental poweroff, for example)
after i restart deluge, and there is no archive with backup files created
in '~/.config/deluge/archive' directory. So, i have to regularly do a
backup of '~/.config/deluge/state' folder to have an ability to restore my
session if it happens again. Typically, it happens not often, but i found
that this issue occurs with 100% possibility if i run deluge and
immediately close it before it fully loads a list of my torrents. If i do
that, next time i launch deluge i have an empty torrent list.

Comment (by Cas):
That is frustrating that this issue is still happening. We will have to
look further into how to prevent this occurring.
* Can you provide details of which files are being lost or corrupted?
* Do you have any logs from the next startup?
* Is this with deluge standalone or deluged?

Hello! [[br]]
Thanks for your reply!
The issue happens with deluge standalone. I have attached 2 logs: [[br]]
'deluge_normal_startup.log' - this log was made after normal startup when
all seeding torrents was successfully resumed. [[br]]
'deluge_torrents_lost.log' - this one was made after all seeding torrents
from the log above was suddenly removed from the list(of course, they was
removed from deluge only, not from hard drive).

Comment (by digifuzzy):
Confirm similar situation(All seeding torrents are not displayed.) on
2.0.3 dev23.
Using Funtoo x86_64 - python 3.7.6.
On restart of deluge (after system reboot) side bar shows correct count of
running torrents but list of seeding torrents is missing from main list.
Selecting different side bar options seeding torrents are missing from
"All Torrents". Torrent listing is being pulled from a server w/ deluge
daemon running, so I suspect the problem is with presentation (my probably
may differ slightly than what OP original observed).

Tried webUI. Same problem occurs.
Was able to get into console. There the count of torrents was wrong and
seeding torrents were missing. However, I was able to pipe the errors to
file. Traceback below appeared:

exactly problem i'm suffering. i have to backup too in cron job. the *.bak
didn't help much as it get overwritten. archive folder helps sometime
until roll'ed after some days gone (let's say i have it restart everyday).
since deluge ran in the background in my downloader box, i don't check it
often.
i propose using "rename()" to fix this problem before the actual exception
is fixed
1. open(torrents.new), write(), close()
2. optionally unlink(torrents) if OS is windows
3. rename(torrents.new, torrents) only after everything's fine:
no exception, no error, no crash, not kill'ed.
since rename() is atomic operation while write() isn't. rename() is a
common way to help better fighting data loss in this case, mostly
exception and unexpected power loss

I think my issue is similar, but slightly different. In my case when this
issue happens the side bar always shows 0 torrents and the transfer list
is also empty. It might happen randomly for me, but i can always reproduce
this behaviour by doing the following:\\\\
1) Do a backup of 'torrents.state' and 'torrents.fastresume' files.\\
2) Start 'deluge-gtk'(in standalone mode).\\
3) It usually takes several seconds to establish connection with the
daemon and load the list of torrents. At this point, before the connection
is established, right after the GUI is shown up, close deluge.\\
4) Start deluge again and it will show an empty list with 0 torrents. It
is great if you did a backup at step 1 because it let you restore your
previous session. Otherwise, you have to manually re-add and recheck all
your torrents from scratch.

I switched deluge to thin client mode, run deluged daemon at the
background, and the issue is completely gone. I can kill daemon/client at
any time and all torrents persist after restart.
