commit 0545f64d24e04a44fc44e67cd23f631fa5b01135 Author: Isis Lovecruft isis@torproject.org Date: Wed Mar 7 23:50:00 2018 +0000

test: Increase time limit for IP creation in an HS test.

This should avoid most intermittent test failures on developer and CI machines, but there could (and probably should) be a more elegant solution.

Also, this test was testing that the IP was created and its expiration time was set to a time greater than or equal to `now+INTRO_POINT_LIFETIME_MIN_SECONDS+5`:

/* Time to expire MUST also be in that range. We add 5 seconds because * there could be a gap between setting now and the time taken in * service_intro_point_new. On ARM, it can be surprisingly slow... */ tt_u64_op(ip->time_to_expire, OP_GE, now + INTRO_POINT_LIFETIME_MIN_SECONDS + 5);

However, this appears to be a typo, since, according to the comment above it, adding five seconds was done because the IP creation can be slow on some systems. But the five seconds is added to the *minimum* time we're comparing against, and so it actually functions to make this test *more* likely to fail on slower systems. (It should either subtract five seconds, or instead add it to time_to_expire.)
