+### RemoveFailedPods
+
+This strategy evicts pods that are in failed status phase.
+You can provide an optional parameter to filter by failed `reasons`.
+`reasons` can be expanded to include reasons of InitContainers as well by setting the optional parameter `includingInitContainers` to `true`.
+You can specify an optional parameter `minPodLifeTimeSeconds` to evict pods that are older than specified seconds.
+Lastly, you can specify the optional parameter `excludeOwnerKinds` and if a pod
+has any of these `Kind`s listed as an `OwnerRef`, that pod will not be considered for eviction.

+**Parameters:**
+
+|Name|Type|
+|---|---|
+|`minPodLifeTimeSeconds`|uint|
+|`excludeOwnerKinds`|list(string)|
+|`reasons`|list(string)|
+|`includingInitContainers`|bool|

-
-There are far too many logging packages out there, with varying degrees of licenses, far too many features (colorization, all sorts of log frameworks) or are just a pain to use (lack of `Fatalln()`?).
-capnslog provides a simple but consistent logging interface suitable for all kinds of projects.
-
-### Design Principles
-
-##### `package main` is the place where logging gets turned on and routed
-
-A library should not touch log options, only generate log entries. Libraries are silent until main lets them speak.
-
-##### All log options are runtime-configurable. 
-
-Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly. 
-
-##### There is one log object per package. It is registered under its repository and package name.
-
-`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs.
-
-##### There is *one* output stream, and it is an `io.Writer` composed with a formatter.
-
-Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer.
-
-Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependent. These are, at best, provided as options, but more likely, provided by your application.
-
-##### Log objects are an interface
-
-An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed.
-
-##### Log levels have specific meanings:
-
-  * Critical: Unrecoverable. Must fail.
-  * Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost
-  * Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning.
-  * Notice: Normal, but important (uncommon) log information.
-  * Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations.
-  * Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices.
-  * Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query.

+These global variables control the behavior of `jsonpatch.Apply`.
+
+An alternative to `jsonpatch.Apply` is `jsonpatch.ApplyWithOptions` whose behavior
+is controlled by an `options` parameter of type `*jsonpatch.ApplyOptions`.
+
+Structure `jsonpatch.ApplyOptions` includes the configuration options above 
+and adds two new options: `AllowMissingPathOnRemove` and `EnsurePathExistsOnAdd`.
+
+When `AllowMissingPathOnRemove` is set to `true`, `jsonpatch.ApplyWithOptions` will ignore
+`remove` operations whose `path` points to a non-existent location in the JSON document.
+`AllowMissingPathOnRemove` defaults to `false` which will lead to `jsonpatch.ApplyWithOptions`
+returning an error when hitting a missing `path` on `remove`.
+
+When `EnsurePathExistsOnAdd` is set to `true`, `jsonpatch.ApplyWithOptions` will make sure
+that `add` operations produce all the `path` elements that are missing from the target object.

+# httpsnoop
+
+Package httpsnoop provides an easy way to capture http related metrics (i.e.
+response time, bytes written, and http status code) from your application's
+http.Handlers.
+
+Doing this requires non-trivial wrapping of the http.ResponseWriter interface,
+which is also exposed for users interested in a more low-level API.
+
+[![GoDoc](https://godoc.org/github.com/felixge/httpsnoop?status.svg)](https://godoc.org/github.com/felixge/httpsnoop)
+[![Build Status](https://travis-ci.org/felixge/httpsnoop.svg?branch=master)](https://travis-ci.org/felixge/httpsnoop)
+
+## Usage Example
+
+```go
+// myH is your app's http handler, perhaps a http.ServeMux or similar.
+var myH http.Handler
+// wrappedH wraps myH in order to log every request.
+wrappedH := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+	m := httpsnoop.CaptureMetrics(myH, w, r)
+	log.Printf(
+		"%s %s (code=%d dt=%s written=%d)",
+		r.Method,
+		r.URL,
+		m.Code,
+		m.Duration,
+		m.Written,
+	)
+})
+http.ListenAndServe(":8080", wrappedH)
+```
+
+## Why this package exists
+
+Instrumenting an application's http.Handler is surprisingly difficult.
+
+However if you google for e.g. "capture ResponseWriter status code" you'll find
+lots of advise and code examples that suggest it to be a fairly trivial
+undertaking. Unfortunately everything I've seen so far has a high chance of
+breaking your application.
+
+The main problem is that a `http.ResponseWriter` often implements additional
+interfaces such as `http.Flusher`, `http.CloseNotifier`, `http.Hijacker`, `http.Pusher`, and
+`io.ReaderFrom`. So the naive approach of just wrapping `http.ResponseWriter`
+in your own struct that also implements the `http.ResponseWriter` interface
+will hide the additional interfaces mentioned above. This has a high change of
+introducing subtle bugs into any non-trivial application.
+
+Another approach I've seen people take is to return a struct that implements
+all of the interfaces above. However, that's also problematic, because it's
+difficult to fake some of these interfaces behaviors when the underlying
+`http.ResponseWriter` doesn't have an implementation. It's also dangerous,
+because an application may choose to operate differently, merely because it
+detects the presence of these additional interfaces.
+
+This package solves this problem by checking which additional interfaces a
+`http.ResponseWriter` implements, returning a wrapped version implementing the
+exact same set of interfaces.
+
+Additionally this package properly handles edge cases such as `WriteHeader` not
+being called, or called more than once, as well as concurrent calls to
+`http.ResponseWriter` methods, and even calls happening after the wrapped
+`ServeHTTP` has already returned.
+
+Unfortunately this package is not perfect either. It's possible that it is
+still missing some interfaces provided by the go core (let me know if you find
+one), and it won't work for applications adding their own interfaces into the
+mix.
+
+However, hopefully the explanation above has sufficiently scared you of rolling
+your own solution to this problem. httpsnoop may still break your application,
+but at least it tries to avoid it as much as possible.
+
+Anyway, the real problem here is that smuggling additional interfaces inside
+`http.ResponseWriter` is a problematic design choice, but it probably goes as
+deep as the Go language specification itself. But that's okay, I still prefer
+Go over the alternatives ;).
+
+## Performance
+
+```
+BenchmarkBaseline-8      	   20000	     94912 ns/op
+BenchmarkCaptureMetrics-8	   20000	     95461 ns/op
+```
+
+As you can see, using `CaptureMetrics` on a vanilla http.Handler introduces an
+overhead of ~500 ns per http request on my machine. However, the margin of
+error appears to be larger than that, therefor it should be reasonable to
+assume that the overhead introduced by `CaptureMetrics` is absolutely
+negligible.
