在临时文件夹中创建的很多临时魔法文件 [英] lot of temp magick files created in temporary folder

问题描述

我正在使用 imagick 库来调整和处理http处理程序中的图像。哪个不在 / tmp 文件夹中写任何内容。但是因为我可以在该文件夹中创建大量这些文件，并且它的大小每天都在增长，目前它正在消耗大约90％的分区大小。此外，我也无法阅读他们的内容。那么，为什么要创建这些文件，一段时间后它们会被删除，还是我需要手动删除它们。

I am using the imagick library to resizing and cropping the images in a http handler. Which doesn't write anything in /tmp folder. But as i can a lot of these files are being created in that folder and it's size is growing on a daily basis and currently it's consuming around 90% of partition size. Moreover, i am not able to read their content also. So, why these files are being created and would they be delete after a while or do i need to manually delete them.

修改：

我的http处理程序中没有使用以下两行。原因是我无法找到任何解释。而且，go http处理程序工作正常。那么，这些陈述的目的是什么？

I am not using the following two lines in my http Handler. Reason being i couldn't find any explanation to do so. Moreover, the go http handler works fine. So, what is the purpose of these statements?

imagick.Initialize() 
defer imagick.Terminate()

我假设有一些理由将它们包含在代码中。所以，在去http处理程序。它应该包含在 func main（）里面还是 serveHTTP 里面？

I am assuming there would be some reason to include them in the code. So, in go http handler. Where it should be included inside func main() or inside serveHTTP ?

func main() {                                           
    myMux := http.NewServeMux()
    myMux.HandleFunc("/", serveHTTP)

    if err := http.ListenAndServe(":8085", myMux); err != nil {
        logFatal("Error when starting or running http server: %v", err)
    }       

}

func serveHTTP(w http.ResponseWriter, r *http.Request) {

}

推荐答案

实际上它应该包含在 func main（）中，而不是在
func serveHTTP中（）。对于长时间运行的应用程序，它应该被调用一次，它解决了我的问题。

Actually it should be included in the func main() not in the func serveHTTP(). It is meant to be called once for a long running application and it solved my problem.

func main() {   

    imagick.Initialize() 
    defer imagick.Terminate()                                        
    myMux := http.NewServeMux()
    myMux.HandleFunc("/", serveHTTP)

    if err := http.ListenAndServe(":8085", myMux); err != nil {
        logFatal("Error when starting or running http server: %v", err)
    }       

}

func serveHTTP(w http.ResponseWriter, r *http.Request) {

}
