build: move e2e dependencies into e2e/go.mod
Several packages are only used while running the e2e suite. These packages are less important to update, as the they can not influence the final executable that is part of the Ceph-CSI container-image. By moving these dependencies out of the main Ceph-CSI go.mod, it is easier to identify if a reported CVE affects Ceph-CSI, or only the testing (like most of the Kubernetes CVEs).

reflect api that avoids runtime reflect.Value cost
|
||||
|
||||
* reflect get/set interface{}, with type checking
|
||||
* reflect get/set unsafe.Pointer, without type checking
|
||||
* `reflect2.TypeByName` works like `Class.forName` found in java
|
||||
|
||||
[json-iterator](https://github.com/json-iterator/go) use this package to save runtime dispatching cost.
|
||||
This package is designed for low level libraries to optimize reflection performance.
|
||||
General application should still use reflect standard library.
|
||||
|
||||
# reflect2.TypeByName
|
||||
|
||||
```go
|
||||
// given package is github.com/your/awesome-package
|
||||
type MyStruct struct {
|
||||
// ...
|
||||
}
|
||||
|
||||
// will return the type
|
||||
reflect2.TypeByName("awesome-package.MyStruct")
|
||||
// however, if the type has not been used
|
||||
// it will be eliminated by compiler, so we can not get it in runtime
|
||||
```
|
||||
|
||||
# reflect2 get/set interface{}
|
||||
|
||||
```go
|
||||
valType := reflect2.TypeOf(1)
|
||||
i := 1
|
||||
j := 10
|
||||
valType.Set(&i, &j)
|
||||
// i will be 10
|
||||
```
|
||||
|
||||
to get set `type`, always use its pointer `*type`
|
||||
|
||||
# reflect2 get/set unsafe.Pointer
|
||||
|
||||
```go
|
||||
valType := reflect2.TypeOf(1)
|
||||
i := 1
|
||||
j := 10
|
||||
valType.UnsafeSet(unsafe.Pointer(&i), unsafe.Pointer(&j))
|
||||
// i will be 10
|
||||
```
|
||||
|
||||
to get set `type`, always use its pointer `*type`
|
||||
|
||||
# benchmark
|
||||
|
||||
Benchmark is not necessary for this package. It does nothing actually.
|
||||
As it is just a thin wrapper to make go runtime public.
|
||||
Both `reflect2` and `reflect` call same function
|
||||
provided by `runtime` package exposed by go language.
|
||||
|
||||
# unsafe safety
|
||||
|
||||
Instead of casting `[]byte` to `sliceHeader` in your application using unsafe.
|
||||
We can use reflect2 instead. This way, if `sliceHeader` changes in the future,
|
||||
only reflect2 need to be upgraded.
|
||||
|
||||
reflect2 tries its best to keep the implementation same as reflect (by testing).
