In https://gitlab.torproject.org/Diziet/arti/-/jobs/1185758 I saw this: ``` ++ grep -c stream-success shadow.data/hosts/torclient-onion-artiserver-full-vanguards/tgen.1003.stdout ++ true + successes=0 + '[' 0 -ge 1 ']' + echo 'Failed. Only got 0 successful streams.' Failed. Only got 0 successful streams. + exit 1 ``` I think it very unlikely this was due to the branch contents. The MR shouldn't have had any effect on any code that actually runs, and the same test case seems to be generally passing on mainline (at least when CI isn't just being random). I looked for tickets about shadow in CI and found several. They all had rather specific titles, and I had no way to pick one. So instead I'm filing this (tracking) ticket about the symptom. FTR my priors say this is probably some kind of misbehaviour by code in Arti than it is an actual fault with shadow.
