Which is mainly generational state (terms) and useful LSNs.
Also add /status basic healthcheck request which is now used in tests to
determine the safekeeper is up; this fixes#726.
ref #115
- perform checkpoint for each tenant repository.
- wait for the completion of all threads.
Add new option 'immediate' to 'pageserver stop' command to terminate the pageserver immediately.
Support is done via pytest-xdist plugin.
To use the feature add -n<concurrency> to pytest invocation
e.g. pytest -n8 to run 8 tests in parallel.
Changes in code are mostly about ports assigning. Previously port for
pageserver was hardcoded without the ability to override through zenith
cli and ports for started compute nodes were calculated twice, in zenith
cli and in test code. Now zenith cli supports port arguments for
pageserver and compute nodes to be passed explicitly.
Tests are modified in such a way that each worker gets a non overlapping
port range which can be configured and now contains 100 ports. These
ports are distributed to test services (pageserver, wal acceptors,
compute nodes) so they can work independently.
by binding sockets before daemonization
also use less annoying error reporting by not printing full error
messages for connect errors in first several connection retries
