- Generated service names come only from a URL host, a key=value DSN's
host=, or a MySQL tcp() address, so a password in a key=value DSN can no
longer end up in the name printed on every log line.
- connect_timeout is added only to postgres:// and postgresql:// URLs
(parsed, so it never lands after a fragment) or as a key=value token, never
glued onto a key=value value containing "://".
- Driver parse errors that quote password fragments (mongo escape errors,
lib/pq's missing "=" error) are replaced with generic hints.
- MongoDB keeps its client only after a successful connect, so a failed
connect is not disconnected twice.
- Couchbase gets ready_timeout plus 1 minute to connect, so raising
ready_timeout takes effect.
- Shutdown waits at most 7 seconds, inside Docker's 10-second grace period.
- Each adapter declares its config keys; unknown keys anywhere in the file,
including under config, log a warning without blocking start.
- Each connect attempt, including initialization, times out after 1 minute,
and PostgreSQL DSNs without connect_timeout get connect_timeout=30, since
lib/pq honours the context only while dialing.
- A service increments right after connecting, so a restart writes even
when the interval outlasts the process.
- A config path that is a directory (Docker's stand-in for a missing
bind-mount source) fails with a clear message.
- Generated service names take the first free suffix, and suffixed names
are reserved so an explicit name cannot silently collide with them.
- counter_key inside a service's config map is rejected instead of being
overwritten.
- Unknown keys in the config file log a warning without blocking start.
- A .dockerignore keeps local configs and .env out of the build context.
Increment read the counter and wrote it back, ignoring the tick context, and
treated any read error as a missing document, so a timeout reset the counter
to 1. A single binary increment is atomic, honours the context, and surfaces
real errors. The cluster is also assigned only after a successful connect so
a failed connect is not closed twice.
Valkey speaks the Redis protocol, so the redis adapter (go-redis) already
serves it. Dropping valkey-go removes a dependency and shrinks the stripped
binary by about 9 MB.
The redis adapter now also closes a client that failed to connect only once.
BREAKING CHANGE: `adapter: valkey` is no longer accepted. Use
`adapter: redis` with a redis:// or rediss:// URL instead of valkey:// or
valkeys://. The namespace option now applies to these services.
Consolidates the *-keepalive family (redis, valkey, postgresql, mysql,
mongodb, couchbase) into a single binary with a runtime DB_TYPE dispatch
and an Adapter interface. Original repos archived with a pointer here.
