Cleaned up code, implemented info content
* Move Content-Type check into serviceHandler
* Custom 404 handler showing the url, mostly for debugging
* Refactored images: better method names and explicit http codes
* Added content to /info
* Added podman fields to Info struct
* Added Container struct

Add a bunch of endpoints
containers: stop, pause, unpause, wait, rm
images: tag, rmi, create (pull only)
Signed-off-by: baude <bbaude@redhat.com>
Add even more handlers
* Add serviceapi/Error() to improve error handling
* Better support for API return payloads
* Renamed unimplemented to unsupported these are generic endpoints
we don't intend to ever support. Swarm broken out since it uses
different HTTP codes to signal that the node is not in a swarm.
* Added more types
* API Version broken out so it can be validated in the future

Split handlers and server packages
The files were split to help contain bloat. The api/server package will
contain all code related to the functioning of the server while
api/handlers will have all the code related to implementing the end
points.
api/server/register_* will contain the methods for registering
endpoints. Additionally, they will have the comments for generating the
swagger spec file.
See api/handlers/version.go for a small example handler,
api/handlers/containers.go contains much more complex handlers.

To not populate +certain fields, use a dash for the name and it will be ignored: + + type Person struct { + Name string `schema:"name"` // custom name + Phone string `schema:"phone"` // custom name + Admin bool `schema:"-"` // this field is never set + } + +The supported field types in the destination struct are: + + * bool + * float variants (float32, float64) + * int variants (int, int8, int16, int32, int64) + * string + * uint variants (uint, uint8, uint16, uint32, uint64) + * struct + * a pointer to one of the above types + * a slice or a pointer to a slice of one of the above types + +Non-supported types are simply ignored, however custom types can be registered +to be converted. + +To fill nested structs, keys must use a dotted notation as the "path" for the +field. So for example, to fill the struct Person below: + + type Phone struct { + Label string + Number string + } + + type Person struct { + Name string + Phone Phone + } + +...the source map must have the keys "Name", "Phone.Label" and "Phone.Number". +This means that an HTML form to fill a Person struct must look like this: + + <form> + <input type="text" name="Name"> + <input type="text" name="Phone.Label"> + <input type="text" name="Phone.Number"> + </form> + +Single values are filled using the first value for a key from the source map. +Slices are filled using all values for a key from the source map. So to fill +a Person with multiple Phone values, like: + + type Person struct { + Name string + Phones []Phone + } + +...an HTML form that accepts three Phone values would look like this: + + <form> + <input type="text" name="Name"> + <input type="text" name="Phones.0.Label"> + <input type="text" name="Phones.0.Number"> + <input type="text" name="Phones.1.Label"> + <input type="text" name="Phones.1.Number"> + <input type="text" name="Phones.2.Label"> + <input type="text" name="Phones.2.Number"> + </form> + +Notice that only for slices of structs the slice index is required. +This is needed for disambiguation: if the nested struct also had a slice +field, we could not translate multiple values to it if we did not use an +index for the parent struct. + +There's also the possibility to create a custom type that implements the +TextUnmarshaler interface, and in this case there's no need to register +a converter, like: + + type Person struct { + Emails []Email + } + + type Email struct { + *mail.Address + } + + func (e *Email) UnmarshalText(text []byte) (err error) { + e.Address, err = mail.ParseAddress(string(text)) + return + } + +...an HTML form that accepts three Email values would look like this: + + <form> + <input type="email" name="Emails.0"> + <input type="email" name="Emails.1"> + <input type="email" name="Emails.2"> + </form> +*/ +package schema diff --git a/vendor/github.com/gorilla/schema/encoder.go b/vendor/github.com/gorilla/schema/encoder.go new file mode 100644 index 000000000..bf1d511e6 --- /dev/null +++ b/vendor/github.com/gorilla/schema/encoder.go @@ -0,0 +1,195 @@ +package schema + +import ( + "errors" + "fmt" + "reflect" + "strconv" +) + +type encoderFunc func(reflect.Value) string + +// Encoder encodes values from a struct into url.Values. +type Encoder struct { + cache *cache + regenc map[reflect.Type]encoderFunc +} + +// NewEncoder returns a new Encoder with defaults. +func NewEncoder() *Encoder { + return &Encoder{cache: newCache(), regenc: make(map[reflect.Type]encoderFunc)} +} + +// Encode encodes a struct into map[string][]string. +// +// Intended for use with url.Values. +func (e *Encoder) Encode(src interface{}, dst map[string][]string) error { + v := reflect.ValueOf(src) + + return e.encode(v, dst) +} + +// RegisterEncoder registers a converter for encoding a custom type. +func (e *Encoder) RegisterEncoder(value interface{}, encoder func(reflect.Value) string) { + e.regenc[reflect.TypeOf(value)] = encoder +} + +// SetAliasTag changes the tag used to locate custom field aliases. +// The default tag is "schema". +func (e *Encoder) SetAliasTag(tag string) { + e.cache.tag = tag +} + +// isValidStructPointer test if input value is a valid struct pointer. +func isValidStructPointer(v reflect.Value) bool { + return v.Type().Kind() == reflect.Ptr && v.Elem().IsValid() && v.Elem().Type().Kind() == reflect.Struct +} + +func isZero(v reflect.Value) bool { + switch v.Kind() { + case reflect.Func: + case reflect.Map, reflect.Slice: + return v.IsNil() || v.Len() == 0 + case reflect.Array: + z := true + for i := 0;
