rbw-agent: Unable to disable PTRACE_ATTACH on this platform: not implemented

[rjc]

Hello,

After installing the latest version with cargo install rbw on macOS 10.14, I get this:

$ rbw --version
rbw 1.1.0
$ rbw login
rbw-agent: Unable to disable PTRACE_ATTACH on this platform: not implemented. Agent memory may be dumpable by other processes.
rbw login: failed to run rbw-agent: exit code: 1

Looks like a possible fall-out from #42.

whoops, sorry, fixed!

[rjc]

@doy, no worries and thanks for the fix! :^)

Now, each time I run any command, I get:

[2021-03-06T09:56:03Z WARN  rbw_agent] failed to disable PTRACE_ATTACH, agent memory may be dumpable by other processes: unimplemented on this platform

I'd rather not use 2>/dev/null each time I run rbw, or create an alias or a script.

Any chance to get rid of the warning altogether on platforms which simply don't support it?

[doy]

oh, oops, the intention was for this to go to the agent logs rather than stdout. that should also be fixed now!

[rjc]

Thanks again for a quick fix!

I actually meant getting rid of the warning altogether on platforms which don't support it quite literally as rbw-agent will be logging an error about missing functionalty which, currently, is Linux-specific. I'm simply wondering if there's much point in it. How about simply mentioning it in the README and be done with the warning? :^)
