Tars is a high-performance RPC framework based on name service and Tars protocol, also integrated administration platform, and implemented hosting-service via flexible schedule.

Overview

TARS - A Linux Foundation Project

What is TARS?

TARS is a Linux Foundation project. It is a high-performance RPC framework based on name service and Tars protocol, also integrated administration platform, and implemented hosting-service via flexible schedule.

Tars, aka TAF(Total Application Framework), has been used in Tencent since 2008. It supports C++, Java, Nodejs and PHP for now. This framework offers a set of solution for development, maintenance and testing, which making development, deployment and testing service efficiently. It integrated extensible protocol for encoding/decoding, high-performance RPC communication framework, name service, monitor, statistics and configuration. You can use it to develop your reliable distributed application based on microservice fast, and reach fully efficient service management.

Nowadays it's used by hundreds of bussiness in Tencent, services that developed base on TAF run on 16 thousands of machines.

See the detailed introduction SUMMARY.md.

Supported platforms

For now it supports OS as below:

  • Linux
  • Mac(>=2.1.0 support)
  • Windows (>= Windows 7)

Supported languages

For now it supports following languages:

  • C++
  • Java
  • Nodejs
  • PHP
  • Go

Version Management

Tars is composed of many modules, scattered in many warehouses, and the basic framework version and language version can develop independently. In view of this, from version 2.1.0, the Framework version tag is printed on the tarsframework warehouse, no longer reflected in the tars warehouse

In addition, each component will have its own version. When there is a version dependency specification, each component will have its own version

Installation

  1. If you are new to Tars, please read documentation installation.
  2. First deploy, please read documentation source.
  3. Install by docker, detail information: docker

    If the A service calls the B service interface too fast, the B service will restart, and there will be no problem calling at a very slow frequency.

    在2.3 使用 tarscloud/framework 部署框架中

    1. 启动框架从节点

    如果希望多节点部署, 则在不同机器上执行 docker run ...即可, 注意参数设置!

    最新版本:

    docker run -d \
        --name=tars-framework-slave \
        --net=tars \
        -e MYSQL_HOST="172.25.0.2" \
        -e MYSQL_ROOT_PASSWORD="123456" \
        -e MYSQL_USER=root \
        -e MYSQL_PORT=3306 \
        -e REBUILD=false \
        -e INET=eth0 \
        -e SLAVE=true \
        --ip="172.25.0.4" \
        -v /data/framework-slave:/data/tars \
        -v /etc/localtime:/etc/localtime \
        docker.tarsyun.com/tarscloud/framework:latest
    

    稳定版本:

    docker run -d \
        --name=tars-framework-slave \
        --net=tars \
        -e MYSQL_HOST="172.25.0.2" \
        -e MYSQL_ROOT_PASSWORD="123456" \
        -e MYSQL_USER=root \
        -e MYSQL_PORT=3306 \
        -e REBUILD=false \
        -e INET=eth0 \
        -e SLAVE=true \
        --ip="172.25.0.4" \
        -v /data/framework-slave:/data/tars \
        -v /etc/localtime:/etc/localtime \
        docker.tarsyun.com/tarscloud/framework:stable
    

    其中

    docker.tarsyun.com/tarscloud/framework:latest docker.tarsyun.com/tarscloud/framework:stable

    这两行镜像地址应该有误,直接运行是不能跑的,会显示错误为:

    Unable to find image 'docker.tarsyun.com/tarscloud/framework:stable' locally docker: Error response from daemon: Get https://docker.tarsyun.com/v2/: x509: certificate signed by unknown authority.

    我在浏览器中输入地址,也是404。

    应该就简单的改成 tarscloud/framework:stabletarscloud/framework:latest吧?

    虽然不是大问题,可能就是一个笔误,但也是抱着尽善尽美的态度提出来啦。

    How do you think about single connection and multi connection (or connection pool) design in RPC framework?

    For example, Baidu's brpc uses a single connection by default, while Google's grpc reuses a connection based on http2?

    Do multiple connections or connection pools theoretically have higher concurrent throughput and lower latency?

    Stringtoproxy in Java will trigger the dead loop bug of concurringhashmap computeifabsent. (JDK version is 1.8)

    1. During system initialization, stringtoproxy notifyhelper's proxy, computeifabsent will lock.
    2. Next, when initializing any proxy for the first time, updateservantendpoints will find available nodes,
    3. At this time, stringtoproxy queryhelper's proxy will be added internally
    4. The same communicator, the same concurringhashmap, the same cache, and the same computeifabsent are in infinite CAS loop.

    When different objs happen to bump into a hashcode, and they are all in computeifabsent, there is a dead cycle.

    如题,我打算使用微服务集成由python和ruby编写的应用,当前查看文档没有找到关于这些语言的处理方式(如果有的话劳烦指明一下位置)。对于一些支持的语言(如nodejs)可以支持打包上传及部署,那么支持之外的语言呢?是否是把节点当做一个服务器,然后将代码上传运行并映射出来就可以了?如果这样做的话,对于服务监控这些是否和nodejs编写的应用是一样的?谢谢大佬。

  • [BUG]当节点经过网关连入主框架时,PUSH配置文件存在问题,无法推送节点配置的内容

    [BUG]当节点经过网关连入主框架时,PUSH配置文件存在问题,无法推送节点配置的内容

    What version of TARS and what language are you using? TarsFramework-3.0.3

    What operating system (Linux, Windows, ...) and version? [e.g. CentOS 7.8] Linux&Windows

    What runtime/compiler are you using? [e.g. JDK version or version of gcc] docker

    Describe the bug 在添加了服务配置和节点配置时(不启用set),PUSH配置文件给经过网关连接上来的节点(已设置nodeid,框架中显示的ip是实际ip)推送文件只会推送服务配置,不会合并节点配置的信息。具体原因是: tars-bug-1 在getScriptFile函数中调用loadConfigByInfo时传入的配置参数是自己新建的对象,构建时只设置了部分信息,不包含host字段 tars-bug-2 后面取host时如果为空则取current->getHostName(),获取到的是连接的实际接入IP,也就是网关IP,而不是节点真实IP tars-bug-3 在最后查库取节点配置时,用网关IP去查,无法获取真正的节点配置,导致推送的配置只有服务配置的内容,没有节点配置的内容。

    getScriptFile函数中可以取到_desc.nodeName,这个能确保是实际的ip?用这个字段给host赋值传入是否可以?
