# bedrock ChangeLog

## 4.5.1 - 2022-04-04

### Fixed
- Fix winston child logger `defaultMeta` override bug.

## 4.5.0 - 2022-03-22

### Added
- Add `main` export that includes information about the main program
  module such as its `filename`. The main program module will be
  properly computed on bedrock workers to express not the worker
  filename but the filename of the first loaded module, e.g., if
  an application `foo.js` calls `bedrock.start`, then `main` includes
  the full path `filename` for `foo.js` whether running in the primary
  process on a worker process.

### Changed
- Change internal implementation to use ESM + transpile using esm.js to
  CommonJS. Should be a non-breaking change.

## 4.4.3 - 2021-12-08

### Fixed
- Ensure primary process does not exit before logger completes or errors so
  that the proper error code is returned.
- Ensure an orderly exit is performed when nothing else is scheduled to
  run on the event loop on the primary process.

## 4.4.2 - 2021-11-04

### Fixed
- Signal handlers that prematurely terminated the primary or its workers
  have been refactored to allow an orderly exit. The primary and worker
  internal messaging and exit process has been cleaned up and simplified to
  help ensure more consistent outcomes and eliminate a number of bugs or
  unexpected states. Additionally, some unused IPC messages were removed.
  The expectation is that these changes do not affect existing applications
  except in those cases where those applications may have been exiting in
  inconsistent ways; the aim is for those applications to now exit the same
  way regardless of IPC message delivery order.

## 4.4.1 - 2021-09-21

### Fixed
- Use `Infinity` for max event listeners instead of using `0` which is a proxy
  for it (from docs: "The value can be set to Infinity (or 0) to indicate an
  unlimited number of listeners.").
  Link: https://nodejs.org/api/events.html#events_emitter_setmaxlisteners_n
  This addresses problems with libraries (such as `esm`) that assume
  `Infinity` will be used and that make erroneous calculations if `0` is used
  instead (e.g., the `esm` library scales the max listeners from `Infinity` to
  `1` when the intention was to increase the max listeners by just `1`).

## 4.4.0 - 2021-07-23

### Added
- Add new config `config.loggers.enableFileTransport` with a default of `true`.
  One can disable all file based logging by setting this value to `false`. This
  is useful for deployment targets such as Kubernetes that are only concerned
  with console logs.

## 4.3.0 - 2021-07-02

### Added
- Add `unhandledRejection` handler to deal with uncaught promises by causing
  the process to exit.

## 4.2.1 - 2021-07-01

### Changed
- Replace 'master' language in process, config, and logging to use 'primary'.
- Backwards compatibility for `config.core.master` (removal planned for 5.x).

## 4.2.0 - 2021-06-30

### Added
- Add POSIX signal handler to emit `bedrock.exit` event prior to exiting.

### 4.1.1 - 2020-12-18

### Fixed
- Fix log levels in worker logger.

## 4.1.0 - 2020-12-09

### Added
- Implement `ensureConfigOverride` configuration setting. This feature provides
  a mechanism for modules and top level applications to require that certain
  configuration values are changed during startup. This is useful when a
  deployment must use a different configuration than the development settings
  to be valid.

## 4.0.0 - 2020-12-07

### Changed
- **BREAKING**: Use Winston logger 3.x. Bedrock configs for the various loggers
  are passed directly into the Winston logger constructors where there have
  been numerous breaking changes. This applies to config objects suchs as
  `config.loggers.console`.  See:
  https://github.com/winstonjs/winston/blob/master/UPGRADE-3.0.md
- Various log formatters may be specified via the Bedrock config. The 'default'
  formatter produces logs that are equivalent to Bedrock 3.x. Custom
  formatters must conform to the `logform` API. See:
  https://github.com/winstonjs/logform
```js
 // formatter options:
 // default, json, logstash or a custom formatter function
config.loggers.console.bedrock.formatter = 'default';
```

## 3.3.1 - 2020-12-07

### Changed
- Replace `lodash` dependency with standalone per method packages.

## 3.3.0 - 2020-10-22

### Added
- Add unique `workerId` per process.

## 3.2.0 - 2020-10-15

### Added
- Log `signal` when workers exit.

## 3.1.2 - 2020-09-09

### Changed
- Update winston-mail dependency.

## 3.1.1 - 2020-05-21

### Changed
- Use GitHub Actions for CI testing.
- Update dependencies.

## 3.1.0 - 2019-11-13

### Fixed
- Use workaround for master/worker child logger issue.

### Changed
- Switch from `getpwnam` in `posix` to `uid-number` package.

## 3.0.1 - 2019-11-08

### Fixed
- Update bedrock-test dependency.

## 3.0.0 - 2019-11-08

### Changed
- **BREAKING**: Update Node.js requirement to v10.12.0.
- **BREAKING**: `bedrock.start()` now returns a promise instead of using a
  callback. Top-level code using the callback should change to `async`/`await`
  or `then`/`catch` as needed.
- **BREAKING**: Update `async-node-events` dependency and update events API.
  - `emit` is now an async function and used instead of passing a callback for
    completion. User code **must** be updated for this change. It is suggested
    to await the `emit` calls and use async listeners or Promises.
- **BREAKING**: `runOnce` callback form is removed in favor of the
  `runOnceAsync` implementation. `runOnceAsync` remains as an alias for
  `runOnce` but is deprecated. Quick fix is to wrap the new `runOnce` with
  `callbackify` and the `fn` param with `promisify`.
- Use master/worker child loggers.

### Removed
- `bedrock.events.emit` wrapper. Using default from `async-node-events`.
- **BREAKING**: Deprecated event object style.

## 2.0.0 - 2019-10-22

### Changed
- **BREAKING**: Remove mocha unit test framework. The test framework now resides
  entirely in the bedrock-test module@4.
- **BREAKING**: Remove `bedrock.jsonld` and related configuration. A jsonld
  document loader is now available in bedrock-jsonld-document-loader@1.

### Added
- `bedrock.util.hasValue` helper API to replace `jsonld.hasValue`.

## 1.18.1 - 2019-07-24

### Fixed
- Fix memory leak and improve error handling in `runOnce` and `runOnceAsync`.

## 1.18.0 - 2019-07-16

### Changed
- Update lodash to 4.17.14.
- Switch to eslint.
- **BREAKING**: Update Node.js engine requirement to >= 8. Note this is due to
  the use of async/await when runOnceAsync was added in 1.16.0.

## 1.17.0 - 2019-05-06

### Changed
- Improve callback function detection in `events.emit` API.

## 1.16.0 - 2019-04-30

### Added
- `bedrock.runOnceAsync` API which is a promise based version of
  `bedrock.runOnce`.

## 1.15.0 - 2019-03-18

### Added
- `bedrock.util.delay` API which is used to create a promise which resolves
  after the specified milliseconds.

### Changed
- Use `uuid-random` for `bedrock.util.uuid`.

## 1.14.0 - 2018-11-29

### Changed
- Change default value of `bedrock.config.jsonld.strictSSL` from `false` to
  `true`. This means that the `jsonld` library's document loader will refuse
  to retrieve documents from sites without proper SSL certificates. This change
  will impact unit tests in Bedrock modules. The `strictSSL` flag will need to
  be set to `false` in the `test.config.js` files for affected modules.

## 1.13.0 - 2018-09-20

### Added
- Add `bedrock-cli.parsed` event.

### Changed
- Update copyright notices.
- Style fixes.

## 1.12.1 - 2018-05-10

### Changed
- Update async-node-events to 1.0.0.

## 1.12.0 - 2018-05-08

### Added
- Return Promise from `events.emit` and `events.emitLater` that
  resolves to `undefined` once the event has been emitted to all
  listeners or to `false` if it was canceled.

## 1.11.0 - 2018-05-08

### Added
- Add `util.callbackify` helper to produce functions that can be
  called with a callback function or that will return a Promise
  if the callback function is omitted. This utility function
  is used in bedrock modules that are written using Promises
  internally and that expose Promise-based public APIs that
  also support legacy callback patterns.

## 1.10.0 - 2018-04-06

### Added
- `--log-exclude` option to eliminate logging from certain modules.

## 1.9.2 - 2018-03-28

### Changed
- Update to newer worker API.
- Improve errors in runOnce calls.
- Use logger to handle uncaught error formatting.

## 1.9.1 - 2018-03-07

### Changed
- Update from istanbul to nyc for coverage.

## 1.9.0 - 2018-03-01

### Changed
- Update jsonld to 1.0.0.

## 1.8.0 - 2018-02-13

### Changed
- Update jsonld to 0.5.x.
- Update many other dependencies.

### Added
- `--log-only` option to log only certain modules.

## 1.7.1 - 2017-11-13

### Fixed
- Update mocha dependency which addresses multiple security vulnerabilities.

## 1.7.0 - 2017-08-10

### Added
- Add `assertNoError(err)` global test helper which makes an assertion that
  `err` should be falsy. If an error does occur, the full error will be
  logged to the console. The additional logging is helpful when troubleshooting
  tests that are failing due to a regression. This helper should be used in
  place of the commonly used `should.not.exist(err)` assertion.

## 1.6.0 - 2017-07-27

### Changed
- Upgrade test related dependencies: mocha, chai, chai-as-promised.

## 1.5.0 - 2017-07-24

### Added
- Add `child(meta)` method to create a child logger with common metadata for
  each logging call. The special `module` meta key can be used to prefix
  messages with `[module] ` and is removed from the message details.
  `child(name)` is a shortcut for `child({module: name})`.

## 1.4.1 - 2017-02-02

### Changed
- Deprecated default values for `config.paths`. A warning will be printed.  A
  future major version will force values to be set by applications.

## 1.4.0 - 2016-12-09

### Added
- Add `config.paths` with `log` and `cache` entries. This is designed to be a
  simple single point of configuration for the root logging and cache paths.

### Changed
- Use computed configs:
  - Add common cache and log paths to config.paths.
  - Use common log path for default log files.

## 1.3.0 - 2016-12-07

### Added
- Add `bedrock.util.config` utilities:
  - Add `bedrock.util.config.Config` OO wrapper API.
  - Common `bedrock.util.config.main` Config wrapper for `bedrock.config`.
  - See README for usage details.
- ci-test target with tap mocha reporter.

### Changed
- Updated dependencies.
- Updated to node >= 6.

## 1.2.5 - 2016-07-29

### Fixed
- Fix chown bug when posix doesn't exist and usernames are used.

## 1.2.4 - 2016-06-09

### Changed
- Improve logging of simple object unhandled errors.

## 1.2.3 - 2016-06-01

### Changed
- Use improved common uncaught exception handler.

## 1.2.2 - 2016-05-30

### Changed
- Update docs.
- Update jscs linter rules.

## 1.2.1 - 2016-04-04

### Fixed
- `enableChownDir` check typo.

## 1.2.0 - 2016-03-30

### Added
- `bedrock.config.loggers.*.bedrock` for bedrock specific options.
- Add `...bedrock.enableChownDir` boolean option to control `chown`ing file
  logger directory to runtime userId.

## 1.1.1 - 2016-02-22

### Fixed
- Check `config.loggers` properties are Objects before accsesing
  sub-properties.  Fixes older configs that set other non-Object meta-data
  along with loggers.

## 1.1.0 - 2016-02-11

### Added
- Add simpler and more explicit mechanism for adding new winston transports.
  Now a call to `bedrock.loggers.addTransport` can be made in event listeners
  handling the `bedrock-loggers.init` event.

## 1.0.10 - 2016-01-31

### Changed
- Updated dependencies.

## 1.0.9 - 2015-10-27

### Changed
- Updated jsonld.js to 0.4.2 to get URDNA2015 support.

## 1.0.8 - 2015-10-15

### Changed
- Initialize jsonld document loader in `bedrock.init` event phase. Done to
  allow access to fully setup config. Warn if default document loader is used
  before jsonld initialized.

### Fixed
- `bedrock.config.jsonld.strictSSL` used if available to configure jsonld
  document loader.

## 1.0.7 - 2015-10-15

### Changed
- `exit` now calls worker kill() vs disconnect() and process.exit(). Appears to
  be more correct and works around a bug in node 4.x.

## 1.0.6 - 2015-09-15

### Changed
- Update posix version to be compatible with node 4.0.0.

## 1.0.5 - 2015-09-14

### Changed
- Updated jsonld and other versions.

## 1.0.4 - 2015-08-27

### Changed
- Updated async to version 1.4.x.

## 1.0.3 - 2015-07-16

### Fixed
- Bug that caused workers to not be restarted.

## 1.0.2 - 2015-07-12

### Fixed
- Handle cycles in log message meta data.

## 1.0.1 - 2015-05-07

### Changed
- Update dependencies.

## 1.0.0 - 2015-04-08

### Changed
- **BREAKING**: A new event `bedrock.admin.init` was introduced that emits
  prior to `bedrock.init`. This new event is emitted while the process has
  any elevated privileges and after it is handled, elevated privileges are
  dropped. This changes `bedrock.init` so that it runs without elevated
  privileges. This only affected `bedrock.server` in a negative way; this
  module has been updated to comply with the change. Also, `bedrock.init`
  should no longer be used to emit custom events; these should be deferred
  to `bedrock.start` to prevent scenarios where a listener of an event
  emitted by one module can't use the API of another unrelated module because
  it hasn't been initialized yet. Deferring custom event emitting to
  `bedrock.start` as a best practice avoids this scenario.
- Updated JSCS rules.

## 0.3.2 - 2015-02-24

### Fixed
- Fixed default command after upgrade to commander 2.6.

## 0.3.1 - 2015-02-23

### Changed
- Updated commander to version 2.6.0.

## 0.3.0 - 2015-02-16
