  pjustice: I added some more diagnosis to that unbound ticket, speculative dtrace ftw
• 12:13
  jperkin
  (to be clear I didn't stumble across that first time, spent a long time code reading and writing manual dtrace probes trying to figure out the code path before finding I could do that instead)
• 12:13
  jperkin
  definitely adding that to my arsenal for next time

  pjustice
  Dang. Quite the opus.

  I was wondering why it was setting IPv6 options, since v6 doesn't work in our environment.

  bahamat
  Because in general, apps can just use inet6 the system will use both inet and inet6, or only inet if inet6 is unavailable.

  E.g., you can listen on `::` and it will implicitly also listen on `0.0.0.0`.

  A couple of us are going to stash that post away as a really nice dtrace example.
• 14:31
  jperkin
  pjustice: yeh I was throwing the idea out on mastodon that we should have some dtrace cookbook site for this stuff
• 14:32
  bahamat
  We do have the dtracetools package.

  we have a dtrace doc somewhere on illumos.org too no?
• 18:56
  sjorge
  where our generic dev guide is?
• 18:56
  sjorge
  that might be a good spot?
• 18:56
  sjorge
  also the smartos wiki has a few nice onelines to help with lx debugging
• 18:57
  jperkin
  that's the official dtrace guide, it's not really a suitable place for dumping snippets and howtos

  also for those not on #illumos I also found that gstrip was losing function argument types for userland CTF, I'm now rebuilding all trunk packages to pick up refreshed builds using native strip(1)
• 19:01
  jperkin
  will mean you can use lovely print(*args[0]) stuff in scripts and get loads of useful information

  jperkin, we use the native strip(1) with '-x' option on omnios. just be aware of issue 15091 when applying it to go binaries:

  illumos.org/issues/15091
• 20:27
  jperkin
  hadfl: yeh we basically disable everything for go: github.com/NetBSD/pkgsrc/blob/trunk/lang/go/go-vars.mk
• 20:27
  jperkin
  ghc also needs a bunch of exclusions
