SSL certificate error

[Thomi Richards]

We use bzr builder to build packages in jenkins. Occasionally, we get an odd SSL-related error. For example, with a recipe that contains:

<code>
# bzr-builder format 0.4
lp:mir
merge target lp:~vanvugt/mir/remove-unused-GraphicRegion
</code>

when we run the following command:

bzr build mir.recipe mir

We sometimes get this output:

<output>
failed to open trace file: [Errno 2] No such file or directory: '/home/ubuntu/.bzr.log'

See `bzr help ssl.ca_certs` for how to specify trusted CAcertificates.
Pass -Ossl.cert_reqs=none to disable certificate verification entirely.

bzr: ERROR: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
</output>

This seems like a very rare issue - less than one time in 100 certainly. Is there anything we can do to help narrow this problem down?

It might be worth collecting information on the timestamps when this happens, if it's still happening. For instance it would be worth knowing if it happened to correlate with Launchpad code or database updates.

This is likely an issue in bzrlib rather than bzr-builder (which just relies on bzrlib for all transports).
