invalid literal for int() in savemessage

[cronfy]

I am using Offlineimap to copy mailbox from corporate mail (dovecot) to Yandex.

While copying messages I get this error:

 ERROR: Exceptions occurred during the run!
 ERROR: Copying message 1 [acc: Test]
  invalid literal for int() with base 10: 'none'
 
Traceback:
  File "/home/spbrsk/imapcopy/offlineimap-7.1.0/offlineimap/folder/Base.py", line 844, in copymessageto
    new_uid = dstfolder.savemessage(uid, message, flags, rtime)
  File "/home/spbrsk/imapcopy/offlineimap-7.1.0/offlineimap/folder/UIDMaps.py", line 268, in savemessage
    newluid = self._mb.savemessage(-1, content, flags, rtime)
  File "/home/spbrsk/imapcopy/offlineimap-7.1.0/offlineimap/folder/IMAP.py", line 692, in savemessage
    uid = int(resp[-1].split(' ')[1])

 ERROR: while syncing INBOX.Sent [account Test]
  invalid literal for int() with base 10: 'none'

resp variable contains following data: ['1493194087 none']

As I am neither python programmer, nor IMAP expert, I have no Idea how to handle it.. How can this be solved?

General informations

• system/distribution (with version): FreeBSD 10.3
• offlineimap version (offlineimap -V): offlineimap v7.1.0, imaplib2 v2.57 (bundled), Python v2.7.12

The target IMAP server looks to not be UIDPLUS compliant contrary to what they pretend. I'll see what we can do on our side.

Usually remote imap responses with something like ['1493212016 790']

['1493194087 none'] is a rare case, probably occuring after some previous error. But when it appears, it does not go away until mailbox is deleted and recreated/resynced from zero.

You might like to try the above patch. ,-)

[cronfy]

Thanks! I will try to use it when error occurs again.

I had same problem again with same sympthoms. It was impossible to continue sync, because offlineimap crashed with traceback.

I applied the patch, it helped, now there are no crashes, just a message:

 ERROR: Unexpected response: ['1493273889 none']

What does this mean? Message was copied or not?

These messages appear on every offlineimap run now (exactly once during the run, 2 in a row):

 ERROR: Unexpected response: ['1493273889 none']
 ERROR: Unexpected response: ['1493273889 none']

And when sync is finished, offlineimap does not exit successfully, it says:

...
Account sync Dmitry:
 *** Finished account 'Dmitry' in 2:00
ERROR: Exceptions occurred during the run!
ERROR: Unexpected response: ['1493273889 none']

Traceback:

    OfflineImapError.ERROR.MESSAGE)

Exit code is 1.

Looks like these 2 messages are copied over and over again on each run:

Folder &BB4EQgQ,BEAEMAQyBDsENQQ9BD0ESwQ1- [remote name INBOX.Sent] [acc: Dmitry]:
 Copy message UID 93 (1/2) DmitrySph:INBOX.Sent -> DmitryYandex
 Copy message UID 94 (2/2) DmitrySph:INBOX.Sent -> DmitryYandex
Folder INBOX [acc: Dmitry]:
 Syncing INBOX: IMAP -> MappedIMAP
Copy message from DmitrySph:INBOX.Sent:
 ERROR: Unexpected response: ['1493273889 none']

Account sync Dmitry:
 *** Finished account 'Dmitry' in 0:08
ERROR: Exceptions occurred during the run!
ERROR: Unexpected response: ['1493273889 none']

... traceback follows...

But they do not seem to be duplicated on target IMAP, thought.

It's not copied. I agree I should improve the message.

Looks like these 2 messages are copied over and over again on each run:

Those 2 messages are the ones that offlineimap tries to copy without success again and again. I have no idea why the server does not return a new UID. I would next manually check the raw content of the faulting mail.

[cronfy]

It seems to me that these 2 messages in question already exist on target IMAP.

This is not a problem for my task anymore, but If you wish, I can try to debug, what do I need to do?

[nicolas33]

I think we can close this issue. This kind of unexpected response is rare enough.

[nicolas33]

Thank you!

Hello, I have this problem in offlineimap 7.0.12+dfsg1-2, which is packaged on Debian Stretch. Is it fixed in later versions or do I need to apply some patch manually?

[nicolas33]

@philip-bl The patch is in since v7.1.1. It won't fix the issue but it will really help understanding what's going on.

Feel free to open a new issue because the root cause might be sightly different.
