commit d4e4ee53e40ba10bdc459b3df660404c1b677d9a Author: Nick Mathewson nickm@torproject.org Date: Wed Feb 27 16:50:52 2019 -0500

Add a chutney "wait_until_bootstrap" command

It waits for up to 20 seconds, checking whether the logged bootstrapped status for every node is 100%. If it is, great: it succeeds. If not, it dumps the bootstrap statuses and exits. --- lib/chutney/TorNet.py | 56 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+)
