Camel Failure on reduced TCP windows - GNOME BUG bae0c64

[James]

[ Description ]

Sometimes evolution can fail to send messages while appearing to do so successfully. This is likely to happen with emails with attachments.

[ QA ]

This will be easiest if you already experience the bug. Try to send many mails with attachments. Make sure they all get sent all the time.

[ Development fix ]

This patch is in ≥ wily

[ Regression potential ]

The function now returns -1 in some situations. Hopefully all callers are OK with that.

[ Original description ]

After digging, identified same in Gnome evolution data server bug bae0c64 which has had patch produced - https://git.gnome.org/browse/evolution-data-server/commit/?id=bae0c64

Originally identified as Evolution not sending emails with attachments. There was no error to screen, message was stored in SENT folder. Mail was never sent. Mail server shows receipt of data error on transmission.

Error logging to console produces:
(evolution:14998): camel-WARNING **: CamelStreamFilter::write() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelStreamFilter::write() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelStreamFilter::write() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelDataWrapper::write_to_stream_sync() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelDataWrapper::decode_to_stream_sync() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelMimePart::write_to_stream_sync() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelMultipart::write_to_stream_sync() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelMimeMessage::write_to_stream_sync() reported failure without setting its GError
(evolution:14998): camel-WARNING **: CamelSmtpTransport::send_to_sync() reported failure without setting its GError

Message is stored in sent folder, Mail server reports error on receive of data. Evolution produces no error.

Status changed to 'Confirmed' because the bug affects multiple users.

[Alexander Koenig (alex-lisas)]

Unfortunately I just noticed that I am affected by this, too. Rebuilding evolution-data-server_3.12.11-0ubuntu1 with the patch provided by James does indeed fix the error. Please consider releasing an updated libcamel package with the fix applied - claiming to have sent email that has not been sent is really a nasty thing to do! I'm adding the patch as it can be found in the Fedora F21 package.

[Alexander Koenig (alex-lisas)]

Sorry, forgot to add the Fedora patch before hitting 'Post'. The patch is identical to the git commit referred by James.

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "F21 patch to fix camel" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

Which version of evolution-data-server are you seeing the problem in?

[Iain Lane (laney)]

Looks like vivid's.

[Iain Lane (laney)]

I uploaded this to the stable update queue now. Once it's accepted you'll get a message & then can grab and test it fixes the problem for you.

Really sorry for the delay.

[Alexander Koenig (alex-lisas)]

Updated to build 3.12.11-0ubuntu1.15.04.1 and successfully sent an email with 0.5MB attachment, which would have failed with the unpatched version before. So from my point of view the fix works as expected.

[Launchpad Janitor (janitor)]

This bug was fixed in the package evolution-data-server - 3.12.11-0ubuntu1.15.04.1
