Bug description:
I'm seeing this on Mako, image #63, devel-proposed.
Periodically, the music scope fails to return any results, leaving a
blank screen.
Looking through the log files, I'm seeing tons of messages such as
this:
[2015-01-13 01:33:27.056262] INFO: SSRegistry:
SmartScopesClient.get_remote_scopes(): GET
https://dash.ubuntu.com/smartscopes/v2/remote-scopes?locale=en_US
[2015-01-13 01:33:27.057239] ERROR: SSRegistry:
SmartScopesClient.get_remote_scopes(): failed to read /custom/partner-id:
unity::FileException: cannot open "/custom/partner-id": No such file or
directory (errno = 2)
[2015-01-13 01:33:46.996259] ERROR: SSRegistry:
SmartScopesClient.get_remote_scopes(): Failed to retrieve remote scopes from
uri: https://dash.ubuntu.com/smartscopes/v2/remote-scopes:
unity::ResourceException: Request timed out:
https://dash.ubuntu.com/smartscopes/v2/remote-scopes?locale=en_US
The request times out even though the remote end works fine. (Easy to
confirm by pasting the same URL into the browser.)
As an aside, the error about /custom/partner-id isn't an error: if the
file doesn't exist (errno = 2), we should say nothing. That'll get rid
of a lot of noise.
In addition, when I run a query, I see all queries to remote scopes
fail (see attached trace).
I'm not familiar with the code. Looking through, I noticed this:
HttpResponseHandle::SPtr response =
http_client_->get(remote_scopes_uri.str(), [&response_str](std::string const&
replyLine) {
response_str += replyLine; // accumulate all reply lines
}, headers);
response->get();
Following this through, it appears that response_str is being appended
to from a different thread without any lock. That looks like it's
wrong to me. But that doesn't explain the timeout exception that is
thrown from response->get().
I suspect a race condition somewhere because, occasionally, I get a
query that works.
