英文:
glob.func in pprof heap profiles
问题
在使用go tool pprof进行堆剖析时，我看到一些条目，例如github.com/anacrolix/utp.glob.func1。这似乎不对应于我能看到的任何命名函数，我猜它是一个闭包。glob是指什么？我如何将这样的名称与适当的函数关联起来？
英文:
When doing a heap profile using go tool pprof, I see some entries like github.com/anacrolix/utp.glob.func1. This doesn't correspond to any named function I can see, I assume it's a closure. What does glob refer to? How can I associate names like this to the appropriate function?

glob指的是全局环境，func1表示匿名函数。因此，它应该指的是某个全局的匿名函数。请查看这个示例及其panic信息：
示例：
package main
import (
"fmt"
)
var (
p = func() string {
panic("a")
return "asdf"
}()
)
func main() {
fmt.Println(p)
}
Panic信息：
panic: a
goroutine 1 [running]:
panic(0x128360, 0x1040a120)
/usr/local/go/src/runtime/panic.go:464 +0x700
main.glob.func1(0x0, 0x0)
/tmp/sandbox715198144/main.go:9 +0x80
main.init()
/tmp/sandbox715198144/main.go:12 +0xa0
英文:
glob refers to global environment, func1 means anonymous function. So it should refer to some global anonymous function. Check this example and its panic information:
Example:
package main
import (
"fmt"
)
var (
p = func() string {
panic("a")
return "asdf"
}()
)
func main() {
fmt.Println(p)
}
Panic information:
panic: a
goroutine 1 [running]:
panic(0x128360, 0x1040a120)
/usr/local/go/src/runtime/panic.go:464 +0x700
main.glob.func1(0x0, 0x0)
/tmp/sandbox715198144/main.go:9 +0x80
main.init()
/tmp/sandbox715198144/main.go:12 +0xa0
