#require serve zstd

Client version is embedded in HTTP request and is effectively dynamic. Pin the
version so behavior is deterministic.

Also disable compression because zstd is optional and causes output to vary
and because debugging partial responses is hard when compression is involved

Failure to accept() socket should result in connection related error message

  $ hg serve --config badserver.closebeforeaccept=true -p $HGPORT -d --pid-file=hg.pid
  $ cat hg.pid > $DAEMON_PIDS

  $ hg clone http://localhost:$HGPORT/ clone

(The server exits on its own, but there is a race between that and starting a new server.
So ensure the process is dead.)

  $ killdaemons.py $DAEMON_PIDS

Failure immediately after accept() should yield connection related error message

  $ hg serve --config badserver.closeafteraccept=true -p $HGPORT -d --pid-file=hg.pid
  $ cat hg.pid > $DAEMON_PIDS

TODO: this usually outputs good results, but sometimes emits abort:
error: '' on FreeBSD and OS X.
What we ideally want are:

abort: error: $ECONNRESET$

The flakiness in this output was observable easily with
--runs-per-test=20 on macOS 10.12 during the freeze for 4.2.
  $ hg clone http://localhost:$HGPORT/ clone
