scalable build pipelines

A

• jenkins as a build tool
• microservices
• how do we standdardize unit testing in our pipeline?
• is a failure because we broke the pipeline, or because the code is bad?
• we’ve recently been trying jenkins declarative pipelines
• bash scripts

trying to implement consistency checking on my prison RSF poller

I wrote a thing to keep the prison index service prototype up-to-date. It works by polling the RSF for updates, and only downloads new entries.

However, the prison register is in discovery and I’m told it will be deleted and reloaded (possibly a number of times). This means that if I only download entries from the last entry number I saw, I’ll miss the entries which have been completely rewritten.

    if len(required_letters) == 2:
        x,y = required_letters
        return "%s.*%s|%s.*%s" % (x,y,y,x)
