Can golang be hot updated?

golang can be hot updated.

Let’s take a look at using go realize to implement hot updates:

Install realize

Because it was installed in the previous project Gin is used as a web framework, so the routes have been written for later testing.

go get github.com/oxequa/realize

During installation, you may be prompted to fail to install a certain package (starting with golang.org). Don’t panic. These packages can be cloned from the golang warehouse and placed in $GOPATH/src/golang.org /x directory.

Configuration

Run realize init for step-by-step configuration. You can also press Enter all the time, and then refer to my configuration and modify it. The name and path under the schema Please write according to the actual situation. If your machine is a Mac, please replace the process killing command with pkill. This step is very important, otherwise Gin will keep prompting like this when recompiling, causing the hot update to fail.

[GIN-debug] [ERROR] listen tcp :8080: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted

Modify the realize package

Execute the following commands in sequence

cd /go/src/github.com/oxequa/realize git fetch git checkout v2.0.2 go get github.com/oxequa/realize

Go to the project directory and run realize start. Hot update is also normal. .
