IntegrityError: PRIMARY KEY must be unique

Steps to reproduce the error

nicolas33 commented 8 years ago

Is this error reproducible on next run for the exact same UID?

jaredmauch commented 8 years ago

if I restart it, it recovers ok. I run offlineimap detached in a screen so don't notice when it fails immediately.

nicolas33 commented 8 years ago

I wonder the error stands because of maxconnections = 4. You only have one idle folder, so I'd try to reduce this value to 2 (or even one if all the emails are downloaded by offlineimap are from INBOX).

I'm pretty sure that's a IDLE issue where offlineimap does the same job twice: trying to save the same UID twice in the database.

jaredmauch commented 8 years ago

is there a good trace i can enable for this? my mailbox is quite large on the backside (~1.37m messages). I can trigger this usually 1-3x a day, so good debugs should be easy to come by.

nicolas33 commented 8 years ago

IntegrityError: PRIMARY KEY must be unique means offlineimap tries to create the same UID twice while this should not happen. The root cause is likely that offlineimap downloads the same UID concurrently. This should never happen. Tracking down issues about concurrency is not easy. I don't think the debug logs will help much.

You might keep maxconnections set to 4 and try v7.0.6 with singlethreadperfolder enabled (new feature). This might help.

nicolas33 commented 8 years ago

I think this issue and #174 are the same. I bet the printed error is different because of the database backend. SQLite is more strict than legacy text.

jaredmauch commented 8 years ago

Ok, have to build a new package and hand to our OS team. I didn't poke at the code, you don't lock the UID to prevent multiple threads from accessing at once?

nicolas33 commented 8 years ago

There's no "lock per UID" concept in the code.

nicolas33 commented 8 years ago

It's possible to install offlineimap as a user: remove the currently installed offlineimap and download the zip (or git clone the repository). Then ./offlineimap.py [options].

jaredmauch commented 8 years ago

yeah, i'd rather the other users pick up 7.0.6 as well. let me do my thing and i'll get back in the next ~24h

jaredmauch commented 8 years ago

Apologies for the late reply, I'm still seeing the issue with 7.0.6:

And does the server has UIDs 289023 and 289027 in the RemoteNTT folder?

jaredmauch commented 8 years ago

Seems so for 23, not for 27.

nicolas33 commented 8 years ago

Weird. Does the next run fail on those UIDs (with and without a full restart)?

jaredmauch commented 8 years ago

due to the error offlineimap stops and i must manually restart it. (i leave it in detached screen and require my password as interactive to launch).

the error does not exist after restart and it proceeds as fine.. it seems if i were to:

while true do; 
    offlineimap;
done

with my password in the rc file it would recover without issue. I have other colleagues who use this as a workaround/solution.

nicolas33 commented 8 years ago

The closed socket is another issue.

The primary key error is likely a bug in concurrency because we download the same UID more than once.

nicolas33 commented 8 years ago

Forget to say that's related to IDLE, IMHO.

nicolas33 commented 8 years ago

Did you enable singlethreadperfolder, BTW?

jaredmauch commented 8 years ago

No, but it's now set

[Repository RemoteNTT]
type = IMAP
singlethreadperfolder =yes
remotehost = mail.us.ntt.net

nicolas33 commented 8 years ago

Well, I'm not sure this setting is honored in IDLE mode. I don't think this can harm, though. Thanks for your tests.

I've looked at the code about IDLE: that sucks.

jaredmauch commented 8 years ago

been running for almost 24h with singlethreadperfolder set.

nicolas33 commented 8 years ago

Good to know! I'll wait for you to get more feedback after more time with this setup. Then, I'll add this information to the documentation.

jaredmauch commented 8 years ago

Been running for a week with no need to restart. perhaps this should just be the default option on the codebase, with setting it to no driving someone to debug it further?

nicolas33 commented 8 years ago

I agree. Notice this feature is recent and still marked experimental. According to your positive feedbacks I think we can enable singlethreadperfolder by default for IDLE mode.

nicolas33 commented 8 years ago

@jaredmauch Done. Could you try the current next branch with the singlethreadperfolder option disabled, please?

nicolas33 commented 8 years ago

Please read unset instead of disabled. IOW, comment the singlethreadperfolder option. Explicitly enabling or disabling the option is still supported in IDLE mode.

jaredmauch commented 8 years ago

yeah, let me pull it onto that host.

Ok. So, singlethreadperfolder reduces the exposure to the concurrency issue without fully fixing it.

btw, still running ok in the background after ~3 days with next

nicolas33 commented 8 years ago

Nice. Seems like singlethreadperfolder is greatly improving IDLE. There might be yet another concurrency issue to explain the latest bug report.

I noticed offlineimap died a few days ago (Sept 26th) and left a 5G core file on the system. (Yes, my mailbox is a beast).

nicolas33 commented 8 years ago

Would be great to report the debug trace. I'm not sure what you mean by a 5G "core file". Do you mean the log file?

jaredmauch commented 8 years ago

No. core file of Python running offlineimap was 5GB. Guessing memory leak.

The memory leak issue will be discussed in #385.

@jaredmauch, could you please check if the path in #438 resolves the issue for you?
