Comment (by arma):

 I think we might want to close this one, either as resolved or as a
 duplicate of #15435?

 Or we can retitle it to simply "Tor dies if you send it a HUP before it
 read its config", but isn't that both kind of expected and also kind of
 unfixable?

  All of this is orthogonal to tor shouldn't crash on an early HUP.

 Tom-or-somebody, did this part get its own ticket?

 Or is this simply a case of it hasn't registered its signal handlers yet,
 what do you expect. Can't-fix.

  I'm strongly tempted to add a PT_EXIT_ON_STDIN_CLOSE env var to the pt
 protocol to facilitate this.

 How much does #15435's fix help this ticket? That is, what else are we
 waiting on here, and how can we move it forward?

 That should be it.  It's worth noting that the latest release of
 obfs4proxy, and newer versions of tor both have also special code to
 attempt to have PTs self terminate even without the env var (via
 `PR_SET_PDEATHSIG`, and ppid monitoring).  Windows is kind of stuck, but
 that's what the env var is for.

Comment (by yawning):

 Somewhat related #5085.

 I believe the issue is generic, and not obfs4proxy specific on the pt
 side.  I suspect obfs4proxy is prone to displaying issues here because
 it's managing to get through the managed pt configuration protocol before
 tor crashes, while obfsproxy and fte (in the example), are slower to start
 up and fail to write the response over stdout.

 In theory something like #10047 could be done PT side if tor didn't close
 the stdin on the PT process, and I'm strongly tempted to add a
 PT_EXIT_ON_STDIN_CLOSE env var to the pt protocol to facilitate this.

 All of this is orthogonal to tor shouldn't crash on an early HUP.
