Package: security-tracker
Severity: important
Hello everybody!
I have been experiencing frequent issues with the web interface of the
security tracker for some weeks and I am still experiencing them:
when visiting the tracker pages [1], I often get the following error
message in my browser:
| Proxy Error
|
| The proxy server received an invalid response from an upstream server.
| The proxy server could not handle the request GET /tracker/DSA-3077-1.
|
| Reason: Error reading from remote server
|
| Apache Server at security-tracker.debian.org Port 443
After a (variable) number of attempts, the web server finally decides
that the page is to be served and everything seems to work fine, until
another error message appears when visiting some other page.
Am I the only one who experiences such issues?
I was hoping to see the problem fixed, but no joy yet...
Could someone please investigate the issue and fix it?
Thanks a lot for your time!
Bye.

I think I may have fixed this in r30431, at least for the time being.
The reason for the issue was that threading support was not actually
active in the Python backend. However, there might now be other
issues because the code has never been tested with threading (but I
was careful when I wrote it not to use global variables for passing
around data, so hopefully there won't be any problems).
The fix is only temporary because at a certain point, broken bots
scraping information from the HTML pages may overload the server
again. There are several of them requesting the same CVE page again
and again, but it's difficult tell what's actually going because of
the privacy-enhanced logging.
