GoFrame v2 development skill. Use only when the target Go project uses or is explicitly adopting GoFrame v2: the nearest go.mod requires github.com/gogf/gf/v2, existing Go files import github.com/gogf/gf/v2 or any github.com/gogf/gf/v2/... component package, or the user asks to scaffold, migrate, or build with GoFrame. Trigger for GoFrame-backed Go work such as APIs/controllers/services, middleware, routing/config, ORM/DAO/DO/entity/database operations, gf CLI/codegen, HTTP/gRPC services, and microservice conventions. Do not trigger for generic Go projects without GoFrame evidence, frontend-only work, shell scripts, or unrelated infrastructure tasks.

:::danger 目前 gproc 组件提供的进程通信特性属于实验性特性! :::

不要通过共享内存来通信,而应该通过通信来共享内存。

常见的进程通信方式有 5 种: 管道/信号/共享内存/共享文件/Socket,这几种方式通常有着各自比较擅长的使用场景。

  • 信号:信号常用在 *nix 系统中,跨平台性比较差,信息传递方式和内容单一。
  • 管道:包括 普通管道 与 命名管道,这种方式在子父进程通信场景比较常用,跨不同关系进程之间通信不太适用。
  • 共享内存/共享文件:按照并发架构的设计来讲,我们尽可能地少用 锁机制,包括共享内存(内存锁)/共享文件(文件锁)其实都是需要依靠锁机制才能保证数据流的正确性,因为锁机制带来的维护复杂度往往会比其带来的收益更高。

gproc 实现的进程通信主要机制采用的是 Socket,这种机制优点是功能比较稳定、使用场景比较通用。

gproc 的进程通信API非常简便,只需通过以下两个方法实现:

func Send(pid int, data []byte) error
func Receive() *Msg

我们通过 Send 方法向指定的进程发送数据(每调用一次相当于发送一条消息),在指定的进程中可以通过 Receive 方法获得数据。其中, Receive 方法提供了类似消息队列的形式来收取其他进程传递的数据,当队列为空时,该方法将会 阻塞 等待。

我们来看一个进程间通信的基本使用示例:

package main

import (
    "context"
    "fmt"
    "github.com/gogf/gf/v2/os/gctx"
    "github.com/gogf/gf/v2/os/gproc"
    "github.com/gogf/gf/v2/os/gtime"
    "github.com/gogf/gf/v2/os/gtimer"
    "os"
    "time"
)

var (
    ctx = gctx.New()
)

func main() {
    fmt.Printf("%d: I am child? %v\n", gproc.Pid(), gproc.IsChild())
    if gproc.IsChild() {
        gtimer.SetInterval(ctx, time.Second, func(ctx context.Context) {
            err := gproc.Send(gproc.PPid(), []byte(gtime.Datetime()))
            if err != nil {
                return
            }
        })
        select {}
    } else {
        m := gproc.NewManager()
        p := m.NewProcess(os.Args[0], os.Args, os.Environ())
        p.Start(ctx)
        for {
            msg := gproc.Receive()
            fmt.Printf("receive from %d, data: %s\n", msg.SenderPid, string(msg.Data))
        }
    }
}

该示例中,我们的主进程启动时创建了一个子进程,该子进程每隔1秒钟向主进程发送当前的时间,主进程收取到子进程发送的参数后输出到终端上。执行后,终端输出的内容如下:

29978: I am child? false
29984: I am child? true
receive from 29984, data: 2018-05-18 15:01:00
receive from 29984, data: 2018-05-18 15:01:01
receive from 29984, data: 2018-05-18 15:01:02
receive from 29984, data: 2018-05-18 15:01:03
receive from 29984, data: 2018-05-18 15:01:04

    The skill provides a comprehensive development guide and code examples for the GoFrame v2 framework. While highly informative for Go developers, it contains several examples with hardcoded placeholder secrets, tokens, and specific local file paths to sensitive configuration files (like Kubernetes credentials). These elements are provided for demonstration purposes but represent insecure practices if used in production without modification.

README badge

README badge for gogf/skills

Provides instruction and conventions for developing with GoFrame v2, a modular Go framework for building HTTP and gRPC services, microservices, and database operations using its ORM, CLI tooling, and project scaffolding. Use this skill when the target project has GoFrame v2 as a dependency or when the user requests scaffolding, migrations, or service development with GoFrame conventions.

Generated from the current SKILL.md.

When should I use this skill?
Use this skill only when your Go project uses GoFrame v2, indicated by github.com/gogf/gf/v2 in go.mod or imports. Do not use for generic Go projects, frontend work, or infrastructure tasks unrelated to GoFrame.
Should I manually set created_at and updated_at fields?
No. GoFrame automatically writes created_at on insert and updated_at on insert/update/save. Manually setting these fields is redundant and violates project conventions.
What should I use for database operations instead of g.Map?
Always use DO objects from internal/model/do/. DO struct fields are interface{}, unset fields remain nil and are automatically ignored by the ORM.
How does soft delete work in GoFrame?
Call Delete() on the DAO; GoFrame automatically converts it to UPDATE SET deleted_at = NOW(). Queries automatically filter out soft-deleted rows without requiring manual WhereNull conditions.
Where should I implement business logic?
Implement business logic directly in the service/ directory. Do not use the logic/ directory unless explicitly requested.
