debug envoy on MacOS with lldb/gdb

[neicunlideyu]

I want to debug envoy on MacOS, so I take following actions:

1. I build envoy binary with command bazel build -c dbg --apple_generate_dsym //source/exe:envoy-static
2. lldb -p {pidOfEnvoy}, set breakpoint breakpoint set --name onConnectionEvent

but the source code doesn't show when break point is hit. Is this supported on MacOS with bazel build? If supported, what option should I add to build phrase?

What's more, can I debug envoy with Xcode?

@zuercher ?

Last I looked bazel does not preserve the dsym files for c++ code and without those files lldb cannot do source level debugging.

I expect using Xcode would have the same problem, but I've not tried.

There's a workaround suggested in bazelbuild/bazel#2537. I don't know if anyone's tried it, though I plan to give it a whirl the next time I want a debugger.
