Coroutine","_content":"# 浅扯 Coroutine\n\n关于 Kotlin Coroutine 的使用就不多说了，大家都已经很熟悉emmm，这里简单探索下 Coroutine 内部的实现，来尽量规避Coroutine 与其他库和框架协同使用时的坑。\n\n本文编写时使用 Kotlin 版本：`1.4-M3`，JDK 版本：`openjdk 11.0.7`\n\nCoroutine 的核心原理 [KEEP][KEEP] 中的 coroutine 提案已经写得很清楚了，详见提案的实现详情章节： [KEEP/proposals/coroutines.md#implementation-details](https://github.com/Kotlin/KEEP/blob/master/proposals/coroutines.md#implementation-details) ，这里补充一点点提案中没说的，和实现高度相关的内容。\n\n本质就是对 suspend 函数进行CPS变换，将代码转换为[延续体传递风格][Continuation-passing style]。简单来说就是为每个函数增加了一个隐式的参数 `$completion`，它的类型是 `Continuation` 即延续体；函数本体则被编译成状态机，状态存储于上述的 `Continuation` 中，suspend 函数每次 resume 时都会被调用，其根据 `Continuation` 中的状态信息直接调转到对应的位置继续执行。\n\n为了便于分析，这里使用 [CFR][CFR] 反编译器对 kotlinc 编译的 suspend 函数进行反编译，当前版本为 `0.150`\n\n我们从下面代码段开始：\n\n```kotlin\nclass Demo {\n suspend fun demo1(s: String) {\n println(\"1==========\")\n delay(100)\n println(\"2==========\")\n }\n}\n```\n\n注意，Kotlin 编译器对其进行编译后我们看到两个 class `Demo$demo1$1.class` `Demo.class` 前面那个是后面的匿名内部类，不用管它，用 cfr 反编译后面的就行了。以下我将只节选部分源码，注意这不是标准的Java代码，没法直接编译\n\n```java\npublic final class Demo {\n /*\n * Unable to fully structure code\n * Enabled aggressive block sorting\n * Lifted jumps to return sites\n */\n @Nullable\n public final Object demo1(@NotNull String s, @NotNull Continuation<? super Unit> $completion) {\n if (!($completion instanceof demo1.1)) ** GOTO lbl-1000\n // 这个 demo1.1 就是下面new出来的那个ContinuationImpl\n var6_3 = $completion;\n if ((var6_3.label & -2147483648) != 0) {\n var6_3.label -= -2147483648;\n } else lbl-1000:\n // 2 sources\n\n {\n $continuation = new ContinuationImpl(this, $completion){\n /* synthetic */ Object result;\n int label;\n final /* synthetic */ Demo this$0;\n Object L$0;\n Object L$1;\n\n @Nullable\n public final Object invokeSuspend(@NotNull Object $result) {\n this.result = $result;\n this.label |= Integer.MIN_VALUE;\n return this.this$0.demo1(null, (Continuation<? super Unit>)this);\n }\n {\n this.this$0 = demo;\n super(continuation);\n }\n };\n }\n $result = $continuation.result;\n var7_5 = IntrinsicsKt.getCOROUTINE_SUSPENDED();\n switch ($continuation.label) {\n case 0: {\n ResultKt.throwOnFailure((Object)$result);\n var3_6 = \"1==========\";\n var4_7 = false;\n System.out.println((Object)var3_6);\n $continuation.L$0 = this;\n $continuation.L$1 = s;\n $continuation.label = 1;\n v0 = DelayKt.delay((long)100L, (Continuation)$continuation);\n if (v0 == var7_5) { // if result == COROUTINE_SUSPENDED\n return var7_5; // return COROUTINE_SUSPEND\n }\n ** GOTO lbl27 // else goto lbl27\n }\n case 1: {\n // 状态机在这里 resume，先恢复局部变量\n s = (String)$continuation.L$1;\n this = (Demo)$continuation.L$0;\n ResultKt.throwOnFailure((Object)$result);\n v0 = $result;\nlbl27:\n // 2 sources\n // 如果一开始就没有挂起，那自然也就不需要恢复咯\n var3_6 = \"2==========\";\n var4_7 = false;\n System.out.println((Object)var3_6);\n return Unit.INSTANCE;\n }\n }\n throw new IllegalStateException(\"call to 'resume' before 'invoke' with coroutine\");\n }\n}\n```\n\n上面这个很清晰了，这个 suspend 真正被调用时会创建一个 ContinuationImpl 的子类，里边存放了状态机的状态 `label` 和局部变量，还有最关键的，传进来的调用者的延续体也被包含在了里面，这个稍后会用到。\n\n当协程挂起时，状态机函数会返回 `COROUTINE_SUSPEND` 这个对象，这也就是 suspend 函数编译后函数返回值必然为 Any 的原因，实际的返回值是 返回值 T 和 COROUTINE_SUSPEND 之一，显然这是在 Java 和 Kotlin 类型系统中均无法表达的。局部变量等状态信息，都会在调用下一个 suspend 函数前保存进延续体 (45~47) \n\n 接下来看一看 CoroutineImpl 这个类到底干了什么，这个类的代码很多，我不全粘过来了，只节选有意义的部分\n\n```kotlin\npublic final override fun resumeWith(result: Result<Any?>) {\n // This loop unrolls recursion in current.resumeWith(param) to make saner and shorter stack traces on resume\n var current = this\n var param = result\n while (true) {\n // Invoke \"resume\" debug probe on every resumed continuation, so that a debugging library infrastructure\n // can precisely track what part of suspended callstack was already resumed\n probeCoroutineResumed(current)\n with(current) {\n val completion = completion!! // fail fast when trying to resume continuation without completion\n val outcome: Result<Any?> =\n try {\n val outcome = invokeSuspend(param)\n if (outcome === COROUTINE_SUSPENDED) return\n Result.success(outcome)\n } catch (exception: Throwable) {\n Result.failure(exception)\n }\n releaseIntercepted() // this state machine instance is terminating\n if (completion is BaseContinuationImpl) {\n // unrolling recursion via loop\n current = completion\n param = outcome\n } else {\n // top-level completion reached -- invoke and return\n completion.resumeWith(outcome)\n return\n }\n }\n }\n }\n```\n\n其实这个函数做的事很简单，不停的循环并调用 current 指针的 invokeSuspend 函数来恢复协程的执行，如果返回 COROUTINE_SUSPEND 那就意味着又是暂停，返回；否则说明当前函数执行完了，从 current 指针指向的延续体中拿出它上一级的延续体，继续 invoke，直到回到根，结束退出。\n\n总结下，传入每个 suspend 函数的延续体在初始时都是调用者的延续体，当 resume 时会传入本函数的延续体，并根据里边的 label 去往相应的状态，同时协程暂停时会返回那个特殊的 COROUTINE_SUSPEND 对象。\n\n\n\n\n\n[Continuation-passing style]: https://en.wikipedia.org/wiki/Continuation-passing_style \"[CPS] 延续体传递风格（WikiPedia[英文]）\"\n\n[KEEP]:

Coroutine\n\n关于 Kotlin Coroutine 的使用就不多说了，大家都已经很熟悉emmm，这里简单探索下 Coroutine 内部的实现，来尽量规避Coroutine 与其他库和框架协同使用时的坑。\n\n本文编写时使用 Kotlin 版本：`1.4-M3`，JDK 版本：`openjdk 11.0.7`\n\nCoroutine 的核心原理 [KEEP][KEEP] 中的 coroutine 提案已经写得很清楚了，详见提案的实现详情章节： [KEEP/proposals/coroutines.md#implementation-details](https://github.com/Kotlin/KEEP/blob/master/proposals/coroutines.md#implementation-details) ，这里补充一点点提案中没说的，和实现高度相关的内容。\n\n本质就是对 suspend 函数进行CPS变换，将代码转换为[延续体传递风格][Continuation-passing style]。简单来说就是为每个函数增加了一个隐式的参数 `$completion`，它的类型是 `Continuation` 即延续体；函数本体则被编译成状态机，状态存储于上述的 `Continuation` 中，suspend 函数每次 resume 时都会被调用，其根据 `Continuation` 中的状态信息直接调转到对应的位置继续执行。\n\n为了便于分析，这里使用 [CFR][CFR] 反编译器对 kotlinc 编译的 suspend 函数进行反编译，当前版本为 `0.150`\n\n我们从下面代码段开始：\n\n```kotlin\nclass Demo {\n suspend fun demo1(s: String) {\n println(\"1==========\")\n delay(100)\n println(\"2==========\")\n }\n}\n```\n\n注意，Kotlin 编译器对其进行编译后我们看到两个 class `Demo$demo1$1.class` `Demo.class` 前面那个是后面的匿名内部类，不用管它，用 cfr 反编译后面的就行了。以下我将只节选部分源码，注意这不是标准的Java代码，没法直接编译\n\n```java\npublic final class Demo {\n /*\n * Unable to fully structure code\n * Enabled aggressive block sorting\n * Lifted jumps to return sites\n */\n @Nullable\n public final Object demo1(@NotNull String s, @NotNull Continuation<? super Unit> $completion) {\n if (!($completion instanceof demo1.1)) ** GOTO lbl-1000\n // 这个 demo1.1 就是下面new出来的那个ContinuationImpl\n var6_3 = $completion;\n if ((var6_3.label & -2147483648) != 0) {\n var6_3.label -= -2147483648;\n } else lbl-1000:\n // 2 sources\n\n {\n $continuation = new ContinuationImpl(this, $completion){\n /* synthetic */ Object result;\n int label;\n final /* synthetic */ Demo this$0;\n Object L$0;\n Object L$1;\n\n @Nullable\n public final Object invokeSuspend(@NotNull Object $result) {\n this.result = $result;\n this.label |= Integer.MIN_VALUE;\n return this.this$0.demo1(null, (Continuation<? super Unit>)this);\n }\n {\n this.this$0 = demo;\n super(continuation);\n }\n };\n }\n $result = $continuation.result;\n var7_5 = IntrinsicsKt.getCOROUTINE_SUSPENDED();\n switch ($continuation.label) {\n case 0: {\n ResultKt.throwOnFailure((Object)$result);\n var3_6 = \"1==========\";\n var4_7 = false;\n System.out.println((Object)var3_6);\n $continuation.L$0 = this;\n $continuation.L$1 = s;\n $continuation.label = 1;\n v0 = DelayKt.delay((long)100L, (Continuation)$continuation);\n if (v0 == var7_5) { // if result == COROUTINE_SUSPENDED\n return var7_5; // return COROUTINE_SUSPEND\n }\n ** GOTO lbl27 // else goto lbl27\n }\n case 1: {\n // 状态机在这里 resume，先恢复局部变量\n s = (String)$continuation.L$1;\n this = (Demo)$continuation.L$0;\n ResultKt.throwOnFailure((Object)$result);\n v0 = $result;\nlbl27:\n // 2 sources\n // 如果一开始就没有挂起，那自然也就不需要恢复咯\n var3_6 = \"2==========\";\n var4_7 = false;\n System.out.println((Object)var3_6);\n return Unit.INSTANCE;\n }\n }\n throw new IllegalStateException(\"call to 'resume' before 'invoke' with coroutine\");\n }\n}\n```\n\n上面这个很清晰了，这个 suspend 真正被调用时会创建一个 ContinuationImpl 的子类，里边存放了状态机的状态 `label` 和局部变量，还有最关键的，传进来的调用者的延续体也被包含在了里面，这个稍后会用到。\n\n当协程挂起时，状态机函数会返回 `COROUTINE_SUSPEND` 这个对象，这也就是 suspend 函数编译后函数返回值必然为 Any 的原因，实际的返回值是 返回值 T 和 COROUTINE_SUSPEND 之一，显然这是在 Java 和 Kotlin 类型系统中均无法表达的。局部变量等状态信息，都会在调用下一个 suspend 函数前保存进延续体 (45~47) \n\n 接下来看一看 CoroutineImpl 这个类到底干了什么，这个类的代码很多，我不全粘过来了，只节选有意义的部分\n\n```kotlin\npublic final override fun resumeWith(result: Result<Any?>) {\n // This loop unrolls recursion in current.resumeWith(param) to make saner and shorter stack traces on resume\n var current = this\n var param = result\n while (true) {\n // Invoke \"resume\" debug probe on every resumed continuation, so that a debugging library infrastructure\n // can precisely track what part of suspended callstack was already resumed\n probeCoroutineResumed(current)\n with(current) {\n val completion = completion!! // fail fast when trying to resume continuation without completion\n val outcome: Result<Any?> =\n try {\n val outcome = invokeSuspend(param)\n if (outcome === COROUTINE_SUSPENDED) return\n Result.success(outcome)\n } catch (exception: Throwable) {\n Result.failure(exception)\n }\n releaseIntercepted() // this state machine instance is terminating\n if (completion is BaseContinuationImpl) {\n // unrolling recursion via loop\n current = completion\n param = outcome\n } else {\n // top-level completion reached -- invoke and return\n completion.resumeWith(outcome)\n return\n }\n }\n }\n }\n```\n\n其实这个函数做的事很简单，不停的循环并调用 current 指针的 invokeSuspend 函数来恢复协程的执行，如果返回 COROUTINE_SUSPEND 那就意味着又是暂停，返回；否则说明当前函数执行完了，从 current 指针指向的延续体中拿出它上一级的延续体，继续 invoke，直到回到根，结束退出。\n\n总结下，传入每个 suspend 函数的延续体在初始时都是调用者的延续体，当 resume 时会传入本函数的延续体，并根据里边的 label 去往相应的状态，同时协程暂停时会返回那个特殊的 COROUTINE_SUSPEND 对象。\n\n\n\n\n\n[Continuation-passing style]: https://en.wikipedia.org/wiki/Continuation-passing_style \"[CPS] 延续体传递风格（WikiPedia[英文]）\"\n\n[KEEP]:

指针的 invokeSuspend 函数来恢复协程的执行，如果返回 COROUTINE_SUSPEND 那就意味着又是暂停，返回；否则说明当前函数执行完了，从 current 指针指向的延续体中拿出它上一级的延续体，继续 invoke，直到回到根，结束退出。</p>\n<p>总结下，传入每个 suspend 函数的延续体在初始时都是调用者的延续体，当 resume 时会传入本函数的延续体，并根据里边的 label 去往相应的状态，同时协程暂停时会返回那个特殊的 COROUTINE_SUSPEND 对象。</p>\n"},{"date":"2019-11-01T13:00:00.000Z","title":"我的 PGP Key","update":"2020-06-10T16:00:00.000Z","_content":"\n# 我的 PGP Key
