[英]golangci-lint - want to "really" ignore a go file not simply analyse it and suppress warnings - my current ignore approach eats memory and is slow
使用golangci-lint
我知道我可以使用skip-dirs
或skip-files
設置,但這些只是在最后停止報告,我認為該工具仍然可以“工作”,引用文檔:
...要跳過哪些文件:它們將被分析,但不會報告它們的問題。 ...
有沒有辦法,比如使用//nolint
的變體來防止某些文件首先被golangci-lint
分析,這樣我們就不會浪費構建時資源 - 內存/cpu - 在它們上面?
我還嘗試了頂部的行,例如// Code generated by XXX. DO NOT EDIT.
// Code generated by XXX. DO NOT EDIT.
和這些類似//nolint
停止報告但我認為golangci-lint
仍在進行分析 - 即當存在大的“被忽略”文件時,工具在高內存的情況下運行緩慢。 從https://github.com/golangci/golangci-lint#nolint我可以做到
> //nolint:unparam
> package pkg
確實沒有報告任何 lint 錯誤,但我仍然使用過多的內存,例如
13:14 $ golangci-lint run --timeout 30m -v

當我刪除大文件時,golangci-lint 表現良好。
使用新的構建標簽來排除golangci-lint
文件實際上減少了它的內存消耗(通過阻止解析文件)
以下示例基於: https : //android.googlesource.com/platform/external/syzkaller/+/01d1494471798d6b91af9813d1d6c3e13a55536c
現在將“有效”跳過的 Go 文件
// AUTOGENERATED FILE
// +build !codeanalysis
package foo
.golangci.yml
run:
deadline: 8m
skip-dirs:
- pkg/kd
# Autogenerated files take too much time and memory to load,
# even if we skip them with skip-dirs.
# So we define this tag and use it in the autogenerated files.
build-tags:
- codeanalysis
我已經用我的設置對此進行了簡要測試,並且該工具不再占用大量內存,與以下方法不同......
//nolint
// Code generated by XXX. DO NOT EDIT.
