- Addons now nest, which means that addons can manage addons. This has a number
of salutary effects - the scripts addon no longer has to poke into the global
addons list, we no longer have to replace/remove/boot-outof parent addons when
we load scripts, and this paves the way for making our top-level tools into
addons themselves.
- All addon calls are now wrapped in a safe execution environment where
exceptions are caught, and output to stdout/stderr are intercepted and turned
into logs.
- We no longer support script arguments in sys.argv - creating an option
properly is the only way to pass arguments. This means that all scripts are
always directly controllable from interctive tooling, and that arguments are
type-checked.
For now, I've disabled testing of the har dump example - it needs to be moved
to the new argument handling, and become a class addon. I'll address that in a
separate patch.
- Add an options parameter to the start() event. This is to be used by addons
on startup to add custom options.
- Add a running() event that is called once the proxy is up and running.
- With the new paradigm we can't log during master __init__, so add a tiny
termstatus addon to print proxy status to terminal once we're running.
This commit is largely based on work by Thiago Arrais (@thiagoarrais)
and Shane Bradfield (@l33tLumberjack). I wasn't really able to get their
PR reasonably merged onto the latest master, so I reapplied their changes
manually here and did some further improvements on that.
