# workerpool history https://github.com/josdejong/workerpool ## 2020-10-03, version 6.0.2 - Fix #32, #175: the promise returned by `Pool.terminate()` now waits until subprocesses are dead before resolving. Thanks @boneskull. ## 2020-09-23, version 6.0.1 - Removed examples from the npm package. Thanks @madbence. ## 2020-05-13, version 6.0.0 WARNING: the library entry points are changed and new source maps are added. This may have impact on your project depending on your setup. - Created separate library entry points in package.json for node.js and browser. Thanks @boneskull. - Generated source maps for both minified and non-minified bundles. - Removed deprecation warnings for `options.nodeWorker` (renamed to `options.workerType`) and `pool.clear()` (renamed to `pool.terminate()`). ## 2019-12-31, version 5.0.4 - Fixed #121: `isMainThread` not working when using `worker_threads`. - Drop official support for node.js 8 (end of life). ## 2019-12-23, version 5.0.3 - Fixed library not working in the browser. See #106. ## 2019-11-06, version 5.0.2 - Fixed environment detection in browser. See #106. Thanks @acgrid. ## 2019-10-13, version 5.0.1 - Fixed #96: WorkerPool not cancelling any pending tasks on termination. ## 2019-08-25, version 5.0.0 - Deprecated option `nodeWorker` and created a new, more extensive option `workerType` giving full control over the selected type of worker. Added new option `'web'` to enforce use a Web Worker. See #85, #74. - In a node.js environment, the default `workerType` is changed from `'process'` to `'thread'`. See #85, #50. - Improved detection of environment (`browser` or `node`), fixing wrong detection in a Jest test environment. See #85. ## 2019-08-21, version 4.0.0 - Pass argument `--max-old-space-size` to child processes. Thanks @patte. - Removed redundant dependencies, upgraded all devDependencies. - Fixed Webpack issues of missing modules `child_process` and `worker_threads`. See #43. - Bundled library changed due to the upgrade to Webpack 4. This could possibly lead to breaking changes. - Implemented new option `maxQueueSize`. Thanks @colomboe. - Fixed exiting workers when the parent process is killed. Thanks @RogerKang. - Fixed #81: Option `minWorkers: 'max'` not using the configured `maxWorkers`. - Fixed not passing `nodeWorker` to workers initialized when creating a pool. Thanks @spacelan. - Internal restructure of the code: moved from `lib` to `src`. ## 2019-03-12, version 3.1.2 - Improved error message when a node.js worker unexpectedly exits (see #58). Thanks @stefanpenner. - Allocate debug ports safely, this fixes an issue cause workers to exit unexpectedly if more then one worker pool is active, and the process is started with a debugger (`node debug` or `node --inspect`). Thanks @stefanpenner. ## 2019-02-25, version 3.1.1 - Fix option `nodeWorker: 'auto'` not using worker threads when available. Thanks @stefanpenner. ## 2019-02-17, version 3.1.0 - Implemented support for using `worker_threads` in Node.js, via the new option `nodeWorker: 'thread'`. Thanks @stefanpenner. ## 2018-12-11, version 3.0.0 - Enable usage in ES6 Webpack projects. - Dropped support for AMD module system. ## 2018-09-12, version 2.3.3 - Fixed space in license field in `package.json`. Thanks @sagotsky. ## 2018-09-08, version 2.3.2 - Add licence field to `package.json`. Thanks @greyd. ## 2018-07-24, version 2.3.1 - Fixed bug where tasks that are cancelled in a Pool's queue causes following tasks to not run. Thanks @greemo. ## 2017-09-30, version 2.3.0 - New method `Pool.terminate(force, timeout)` which will replace `Pool.clear(force)`. Thanks @jimsugg. - Fixed issue with never terminating zombie child processes. Thanks @jimsugg. ## 2017-08-20, version 2.2.4 - Fixed a debug issue: look for `--inspect` within argument strings, instead of exact match. Thanks @jimsugg. ## 2017-08-19, version 2.2.3 - Updated all examples to neatly include `.catch(...)` callbacks. ## 2017-07-08, version 2.2.2 - Fixed #25: timer of a timeout starting when the task is created instead of when the task is started. Thanks @eclipsesk for input. ## 2017-05-07, version 2.2.1 - Fixed #2 and #19: support for debugging child processes. Thanks @tptee. ## 2016-11-26, version 2.2.0 - Implemented #18: method `pool.stats()`. ## 2016-10-11, version 2.1.0 - Implemented support for registering the workers methods asynchronously. This enables asynchronous initialization of workers, for example when using AMD modules. Thanks @natlibfi-arlehiko. - Implemented environment variables `platform`, `isMainThread`, and `cpus`. Thanks @natlibfi-arlehiko. - Implemented option `minWorkers`. Thanks @sergei202. ## 2016-09-18, version 2.0.0 - Replaced conversion of Error-objecting using serializerr to custom implementation to prevent issues with serializing/deserializing functions. This conversion implementation loses the prototype object which means that e.g. 'TypeError' will become just 'Error' in the main code. See #8. Thanks @natlibfi-arlehiko. ## 2016-09-12, version 1.3.1 - Fix for a bug in PhantomJS (see #7). Thanks @natlibfi-arlehiko. ## 2016-08-21, version 1.3.0 - Determine `maxWorkers` as the number of CPU's minus one in browsers too.
