Alex Vandiver 2a12fedcf1 tornado: Remove explicit tornado_processes setting; compute it. ... We can compute the intended number of processes from the sharding configuration. In doing so, also validate that all of the ports are contiguous. This removes a discrepancy between `scripts/lib/sharding.py` and other parts of the codebase about if merely having a `[tornado_sharding]` section is sufficient to enable sharding. Having behaviour which changes merely based on if an empty section exists is surprising. This does require that a (presumably empty) `9800` configuration line exist, but making that default explicit is useful. After this commit, configuring sharding can be done by adding to `zulip.conf`: ``` [tornado_sharding] 9800 = # default 9801 = other_realm ``` Followed by running `./scripts/refresh-sharding-and-restart`.		2020-09-18 15:13:40 -07:00
