| | 15 | |
| | 16 | ### Added |

| | 19 | |
| | 20 | ### Breaking Changes |
| | 21 | |
| | 22 | - `AbstractWorker` class `maxInactiveTime`, `killBehavior` and `async` attributes have been removed in favour of the same ones in the worker options `opts` public attribute. |
| | 23 | - `AbstractWorker` class `lastTask` attribute have been renamed to `lastTaskTimestamp`. |
| | 24 | - `AbstractWorker` class `interval` attribute have been renamed to `aliveInterval`. |

| | 34 | |
| | 35 | ### Bug fixes |

| | 40 | ## [2.0.0] - 2021-01-03 |
| | 41 | |
| | 42 | ### Bug fixes |
| | 43 | |
| | 44 | - Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70). |
| | 45 | |
| | 46 | ### Breaking Changes |
| | 47 | |
| | 48 | - `FullPool` event is now renamed to `busy`. |
| | 49 | - `maxInactiveTime` on `ThreadWorker` default behavior is now changed, if you want to keep the old behavior set `killBehavior` to `KillBehaviors.HARD`. |
| | 50 | _Find more details on our JSDoc._ |
| | 51 | |
| | 52 | - `maxTasks` option on `FixedThreadPool` and `DynamicThreadPool` is now removed since is no more needed. |
| | 53 | |
| | 54 | - We changed some internal structures, but you shouldn't be too affected by them as these are internal changes. |
| | 55 | |
| | 56 | ### Pool options types declaration merge |
| | 57 | |
| | 58 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. |
| | 59 | |
| | 60 | #### New `export` strategy |
| | 61 | |
| | 62 | ```js |
| | 63 | // Before |
| | 64 | const DynamicThreadPool = require('poolifier/lib/dynamic') |
| | 65 | // After |
| | 66 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
| | 67 | ``` |
| | 68 | |
| | 69 | But you should always prefer just using |
| | 70 | |
| | 71 | ```js |
| | 72 | const { DynamicThreadPool } = require('poolifier') |
| | 73 | ``` |
| | 74 | |
| | 75 | #### New type definitions for input data and response |
| | 76 | |
| | 77 | For cluster worker and worker-thread pools, you can now only send and receive serializable data. |
| | 78 | _This is not a limitation by poolifier but NodeJS._ |
| | 79 | |
| | 80 | #### Public property replacements |
| | 81 | |
| | 82 | `numWorkers` property is now `numberOfWorkers` |
| | 83 | |
| | 84 | #### Internal (protected) properties and methods renaming |
| | 85 | |
| | 86 | These properties are not intended for end users |
| | 87 | |
| | 88 | - `id` => `nextMessageId` |
| | 89 | |
| | 90 | These methods are not intended for end users |
| | 91 | |
| | 92 | - `_chooseWorker` => `chooseWorker` |
| | 93 | - `_newWorker` => `createWorker` |
| | 94 | - `_execute` => `internalExecute` |
| | 95 | - `_chooseWorker` => `chooseWorker` |
| | 96 | - `_checkAlive` => `checkAlive` |
| | 97 | - `_run` => `run` |
| | 98 | - `_runAsync` => `runAsync` |
| | 99 | |
