# Changelog
## Unreleased
## 0.3.0.0
### Breaking Changes
- Add the `sweepStaleOnStart` field to `Config`. Exhaustive constructor uses of
`Config` must be updated.
### New Features
- Add `sweepStaleInstances` and default-enabled `sweepStaleOnStart` to reclaim
abandoned temporary PostgreSQL clusters on later startup. Live consumers hold
external lifetime locks across initialization, cache restore, and restart.
### Bug Fixes
- Verify process identity before bounded fast shutdown; preserve uncertain data,
permanent directories, sockets, snapshots, and reusable caches.
- Resolve Linux `ps` through `PATH` so process inspection works with Nix-provided
procps.
### Other Changes
- Consolidate cached startup fallbacks into one protected allocation and preserve
asynchronous cancellation during cache and resource operations.
- Validate Linux suites locally with Apple containers and the pinned Nix test
shell instead of Debian Dockerfiles.
## 0.2.2.0
### Bug Fixes
- Make initdb cache creation atomic by copying into a same-parent temporary
directory and publishing it with an atomic rename. Concurrent cold-cache
writers now treat an existing final cache as success instead of exposing a
partially-copied `data` directory.
## 0.2.1.0
### Bug Fixes
- Fix `stop` and `restart` ignoring configured shutdown mode and timeout — they
were hardcoding `ShutdownGraceful` with a 30-second timeout instead of using
the config values, causing `with`/`withCached` to block unnecessarily on shutdown
### Other Changes
- Change default shutdown mode to `ShutdownFast` (SIGINT) with a 5-second
timeout, which is more appropriate for a testing library
## 0.2.0.1
### Bug Fixes
- Suppress pg_isready stdout/stderr during connection polling
## 0.2.0.0
### Breaking Changes
- Remove Hungarian-style field prefixes from all record types using
`NoFieldSelectors`, `DuplicateRecordFields`, and `OverloadedRecordDot`
- `Config`: `configPort` → `port`, `configDatabaseName` → `databaseName`, etc.
- `Database`: `dbPort` → `port`, `dbDataDirectory` → `dataDirectory`, etc.
- `PostgresProcess`: `postgresProcess` → `process`, `postgresPid` → `pid`
- `DumpOptions`: `dumpFormat` → `format`, `dumpCreateDb` → `createDb`, etc.
- `Snapshot`: `snapshotPath` → `path`, `snapshotTemporary` → `temporary`
- `CacheKey`: `cacheKeyPgVersion` → `pgVersion`, `cacheKeyConfigHash` → `configHash`
- `CacheConfig`: `cacheConfigRoot` → `root`, `cacheConfigCow` → `cow`, `cacheConfigEnabled` → `enabled`
- Error types: all prefixed fields renamed similarly
- Remove accessor functions from `Database` module (`dataDirectory`, `socketDirectory`,
`port`, `databaseName`, `user`); use dot syntax instead (e.g., `db.port`)
- `Database` is now exported with `(..)` from `EphemeralPg` for `HasField` resolution
- Consumers should enable `OverloadedRecordDot` to access record fields
## 0.1.0.0
- Initial release
- Core functionality: `with`, `withConfig`, `start`, `stop`
- Hasql integration via `connectionSettings`
- initdb caching support
- Copy-on-write support for macOS and Linux
- Snapshot support
