我在参考贵司该项目时有几个问题困扰？
①：请问贵司出于什么考虑将之前的Mongo换成mysql了呢？（我司重度mongo用户😂）
②：Mongo不可以做微服务的存储仓吗？
③：该项目的分布式事务时啥方案啊？

劳烦解惑啊

这里 先get再watch，在两个执行过程中，如果刚好有新的服务在load之后、watch之前注册了，那这个服务可能不会被发现，可以尝试在 load 与 watch 中间加 sleep 进行测试复现

c.load(cli, key)
c.watchGroup.Run(func() {
	c.watch(cli, key)
})

goctl 支持pgsql生成?

提供admin可选插件可以直接支持系统状态的简单查看监控，作为一个独立框架感觉会更完善

我还没读代码，先提一个问题。请问全局事物这部分如何设计的？

想改造成 https 协议的，可以配置实现吗

背景

• 罗马不是一天建成的，系统功能的实现也不会是一蹴而就的。今天开发A功能，明天开发B功能，后天开发C功能，而开发A功能时，大概率不会想清楚后续的Z功能的具体实现。
• 假设我今天开发A功能，并且写了一个a.api文件。过几天，我开发B功能，写了一个b.api。我想通过goctl api go --api b.api生成B功能相关的代码，但是就会遇到类似截图中的困境：无法在当前项目目录下生成B功能相关的代码，如果选择生成，之前开发的功能的部分代码就会被覆盖掉（types.go、routes.go等）。

需求

• goctl工具能够支持迭代式的代码生成且保证不会覆盖已有代码

方案（个人浅见）

• 支持覆盖和追加两种代码生成模式。比如在二次执行goctl api go --api xxx.api时，由操作人选择是覆盖或者追加到已有的代码文件中（types.go、routes.go等）。
• 将代码进一步划分到不同的源代码文件中，做到更彻底点的模块化。举例来说，a.api生成的types相关的代码就放置在types/a.go中，b.api生成的types相关的代码就放置在types/b.go中。这样一来，b模块代码的生成不会直接覆盖掉以后的代码。其他模块也类似。如果能做到包级的相互隔离就更赞了。

goctl创建的项目 run的时候报如下错误，这个是依赖版本有问题嘛？

timer.item.removed = true
newItem := &timingEntry{
baseEntry: task,
value: timer.item.value,
}
tw.slots[pos].PushBack(newItem)
tw.setTimerPosition(pos, newItem)
以上代码中，旧的task的removed被标记为了true，但是新、旧task在timers里都是同样的key，当执行到旧task时从timers里移除了该key，当再move或remove新task的时候由于key已经不存在，导致执行失效了。

一下代码可以测试出bug:

const testStep = time.Second

func TestMoveTask(t *testing.T) {
keys := make([]string, 0)
tw, _ := NewTimingWheel(testStep, 10, func(k, v interface{}) {
keys = append(keys, k.(string))
fmt.Printf("%v\n", k)
})

fmt.Printf("第一次SetTimer\n")
tw.SetTimer("first", "v1", testStep * 8)
time.Sleep(testStep * 6)

fmt.Printf("move task\n")
tw.MoveTimer("first", testStep * 7)

time.Sleep(testStep * 3)

fmt.Printf("remove task\n")
tw.removeTask("first")

time.Sleep(testStep * 30)

assert.Equal(t, 0, len(keys))

}

1. Missing 'go_package' option in "transform.proto"

2. --go_out: protoc-gen-go: plugins are not supported; use 'protoc --go-grpc_out=...' to generate gRPC

错误版本

• goctl version 20201021 darwin/amd64

描述

internal/svc/servicecontext.go 中 NewErr 返回 errPicker 参数与 Picker 不一致

errPicker 为3个, Picker 为 2个

func (ep *errPicker) Pick(context.Context, balancer.PickInfo) (balancer.SubConn, func(balancer.DoneInfo), error) {
	return nil, nil, ep.err
}


type Picker interface {
	Pick(info PickInfo) (PickResult, error)
}

具体代码

package picker

import (
	"context"

	"google.golang.org/grpc/balancer"
)

// NewErr returns a picker that always returns err on "Pick".
func NewErr(err error) Picker {
	return &errPicker{p: Error, err: err}
}

type errPicker struct {
	p   Policy
	err error
}

func (ep *errPicker) String() string {
	return ep.p.String()
}

func (ep *errPicker) Pick(context.Context, balancer.PickInfo) (balancer.SubConn, func(balancer.DoneInfo), error) {
	return nil, nil, ep.err
}

操作:

mkdir hello && cd hello
goctl rpc template -o=hello.proto
goctl rpc proto -src hello.proto
go run hello.go

具体错误如下:

go-zero支持tcp长链吗？或者有比较好的思路？

麻雀虽小，五脏俱全的那种，一个简单的博客网站就行。

什么时候支持k8s？

语鹊的文档地址：https://www.yuque.com/tal-tech/go-zero/zig6zy

文中说的“带上 dts.insertExecutor.Wait()，当然要等待全部的 goroutine task 完成”，我做了个实验，代码如下：
executor := executors.NewBulkExecutor(
myExecutor,
executors.WithBulkInterval(time.Second*3), // 3s会自动刷一次container中task去执行
executors.WithBulkTasks(16), // container最大task数。一般设为2的幂次
)
for i := 0; i < 20; i++ {
executor.Add(i)
}
executor.Wait()
// time.Sleep(10 * time.Second)
// executor.Flush()
如果把executor.Flush()注释掉，只会打印出0到15，进程就退出了，剩下的任务就丢失了。因为periodicalexecutor.go里的 pe.waitGroup.Add(1) 是在子协程里调用的，所以调用了executor.Wait()主协程也等不到子协程到ticker的时间自动去flush就退出了，所以16到20的任务就丢失了。在主协程调用executor.Flush()，其实是把剩下的任务取出到了主协程来执行了，如果忘了的话就会丢任务。或者主协程执行的时间足够长，能让子协程达到ticker的时间自动去flush。

如题，希望能同时支持 http 和 rpc 这样的多种协议

系统信息：

go版本：

异常信息：

这种情况我在家里的macOS试了，执行goctl api new test是没有问题的，但公司配的是Windows，在公司电脑上会出现这种异常信息，所以我的想法就是系统平台的原因，另外Windows下执行这边命令后，生成的目录也是不全的，如图：

建议：利用反射获取结构体注解的文档注释，自动生成swagger文档
可参考：https://github.com/henrylee2cn/apiware 项目实现。
Apiware将Go语言net/http及fasthttp请求的指定参数绑定到结构体，并验证参数值的合法性。 建议您可以使用结构体作为web框架的Handler，并用该中间件快速绑定请求参数，节省了大量参数类型转换与有效性验证的工作。同时还可以通过该结构体标签，创建swagger的json配置文件，轻松创建api文档服务。

• 一旦接口数量变多，将不同接口定义到不同的.api文件中进行归类就变得自然而然了。在一个入口的.api文件中include多个.api文件，goctl执行时只需要指定一个入口的.api文件。
• 当然，这是一个锦上添花的功能，目前的方式依然可以正常使用。

疑问🤔️：网上查了以下，说是 github.com/golang/protobuf v1.3.2 依赖的版本太低了，但是就是因为之前是 1.4.1 导致有问题才做了降级，现在这个问题该怎么处理呢，不可能再做升级处理吧

why not use hystrix-go but implementing one yourself. Could you please talk about some comparisons between core/breaker and hystrix-go. I'm curious about the new design, thx.

rt

目前看了下core/store/redis里面redis连接的代码，redis pool参数都是默认的，满足不了所有公司的需求，比如redis的最大连接数、redis的最大空闲数以及超时时间等，这样会更灵活一些？

按照例子 ”快速构建高并发微服务“
https://github.com/tal-tech/go-zero/blob/master/doc/shorturl.md

就像：

types.TypeString(xxx, qualifier)

What issue is？
/kind/feat

What happended?
When I use goctl to generate model but goctl tells me that unexpected database type: json.Maybe there are other some types which goctl is not supported.

https://www.yuque.com/tal-tech/go-zero/ze9i30
import "foo1.api"
import "foo2.api"
应该是没有引号的.

另外goland插件上 对import支持的也是带引号的. 没引号就会提示错误,
命令行运行没问题.

应该是带引号的 goctl里可能没把引号去掉

• 所有日志统一格式

目前有些级别的日志有文件名和行数内容输出，比如error级别日志，有些级别的日志无文件名和行数内容输出，例如

{"@timestamp":"2020-10-25T18:39:21.376+08","level":"slow","content":"hello slow world"}
{"@timestamp":"2020-10-25T18:39:21.376+08","level":"stat","content":"hello stat world"}
{"@timestamp":"2020-10-25T18:39:21.376+08","level":"info","duration":"61000.0ms","content":"hello"}
{"@timestamp":"2020-10-25T18:39:21.376+08","level":"error","duration":"61000.0ms","content":"logging.go:28 hello"}
{"@timestamp":"2020-10-25T18:39:21.376+08","level":"error","duration":"1000.0ms","content":"logging.go:10 world"}

建议所有日志统一添加文件名以及行数

• 建议类似zap添加debug级别的日志

请教一下大佬，bookstore中，我需要生成哪些dockerfile,怎么生成？然后怎么用？
如果需要在k8s中部署，有没有可以参考的配置文件？
谢谢

1. mkdir go-zero
2. go mod init study/go-zero
3. goctl api -o greet.api
4. goctl api go -api greet.api -dir greet

imports (
    "go-zero/greet/internal/svc" // 生成的
    "study/go-zero/greet/internal/svc" // 期望的
)

调试发现auth.Authenticate 这个方法没有走，是哪里设置错了吗？

Auth: true
StrictControl: false

出不出相应的视频教程啊？

1:goctl工具的bug，拉去的最新源码编译的

看不到版本号信息
2:在win10上运行goctl api go -api .\api\shorturl\shorturl.api -dir api

rpc error: code = Unknown desc = sql: Scan error on column index 12, name "DELISTINGDATE": unsupported Scan, storing driver.Value type into type *time.Time

字段定义: DELISTINGDATE datetime DEFAULT NULL，当值为null时解析报错了
