rig_redis 0.4.0

rig_redis: ^0.4.0 copied to clipboard

• The suite marker rule moved into rig; this package now uses it. No API change.
• Fixed along the way: reading an index marker no longer throws when another suite's teardown removes it at the same moment.

No functional change in this package. It moves to rig: ^0.3.0, because ^0.2.0 does not admit rig 0.3.0 and would otherwise hold you to rig 0.2.x.

No functional change in this package. It moves to rig: ^0.2.0, because ^0.1.0 does not admit rig 0.2.0 and would otherwise hold you to rig 0.1.x.

One consequence is worth knowing: rig 0.2.0 changes every configuration hash, so the containers 0.1.0 left running are not reused. The first run on this version creates fresh ones and leaves the old ones behind; rig prune clears them.

First release.

• useRedis() gives a test suite a Redis container and a connection string for it.
• The official image ships no healthcheck, so this module injects one. redis-cli ping can exit 0 even when it failed (e.g. against a password-protected server it was not authenticated for), so the injected check greps the output for PONG instead of trusting the exit code.
• A password is genuinely enforced. Passing password: starts the container with --requirepass; a connection with the wrong password is refused, not silently accepted.
• databases: sets the container's own database count and defaults to 64, not the official image's default of 16 — a shared container's databases are shared across every suite and every project that lands on it, not per project.
• A database index per suite. Suites sharing a container each get their own index (RedisIsolation.database, the default), claimed from the pool databases: sizes and released when the suite ends; index 0 is reserved for RedisIsolation.none, which connects suites to the container's own database on purpose. An index left behind by a suite that crashed before teardown is reclaimed by a later suite and flushed before being handed out, so it never carries a crashed suite's keys.
• Speaks to the server through redis-cli inside the container, so this package adds no Redis client dependency.
