Allow additional arguments to be passed into hooks

Browse source 
If a packager wants to be able to support addititional arguments on his
hook this will allow them to setup the configuration with these arguments.

For example this would allow a hook developer to add support for a --debug
flag to change the level of debugging in his hook.

In order to complete this task, I had to vendor in the latest
github.com://opencontainers/runtime-tools, which caused me to have to fix a
Mount and Capability interface calls

do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

# gojsonschema
## Description
An implementation of JSON Schema, based on IETF's draft v4 - Go language
References :
* http://json-schema.org
* http://json-schema.org/latest/json-schema-core.html
* http://json-schema.org/latest/json-schema-validation.html
## Installation
```
go get github.com/xeipuuv/gojsonschema
```
Dependencies :
* [github.com/xeipuuv/gojsonpointer](https://github.com/xeipuuv/gojsonpointer)
* [github.com/xeipuuv/gojsonreference](https://github.com/xeipuuv/gojsonreference)
* [github.com/stretchr/testify/assert](https://github.com/stretchr/testify#assert-package)
## Usage
### Example
```go
package main
import (
"fmt"
"github.com/xeipuuv/gojsonschema"
)
func main() {
schemaLoader := gojsonschema.NewReferenceLoader("file:///home/me/schema.json")
documentLoader := gojsonschema.NewReferenceLoader("file:///home/me/document.json")
result, err := gojsonschema.Validate(schemaLoader, documentLoader)
if err != nil {
panic(err.Error())
}
if result.Valid() {
fmt.Printf("The document is valid\n")
} else {
fmt.Printf("The document is not valid. see errors :\n")
for _, desc := range result.Errors() {
fmt.Printf("- %s\n", desc)
}
}
}
```
#### Loaders
There are various ways to load your JSON data.
In order to load your schemas and documents,
first declare an appropriate loader :
* Web / HTTP, using a reference :
```go
loader := gojsonschema.NewReferenceLoader("http://www.some_host.com/schema.json")
```
* Local file, using a reference :
```go
loader := gojsonschema.NewReferenceLoader("file:///home/me/schema.json")
```
References use the URI scheme, the prefix (file://) and a full path to the file are required.
* JSON strings :
```go
loader := gojsonschema.NewStringLoader(`{"type": "string"}`)
```
* Custom Go types :
```go
m := map[string]interface{}{"type": "string"}
loader := gojsonschema.NewGoLoader(m)
```
And
```go
type Root struct {
Users []User `json:"users"`
}
type User struct {
Name string `json:"name"`
}
...
data := Root{}
data.Users = append(data.Users, User{"John"})
data.Users = append(data.Users, User{"Sophia"})
data.Users = append(data.Users, User{"Bill"})
loader := gojsonschema.NewGoLoader(data)
```
#### Validation
Once the loaders are set, validation is easy :
```go
result, err := gojsonschema.Validate(schemaLoader, documentLoader)
```
Alternatively, you might want to load a schema only once and process to multiple validations :
```go
schema, err := gojsonschema.NewSchema(schemaLoader)
...
result1, err := schema.Validate(documentLoader1)
...
result2, err := schema.Validate(documentLoader2)
...
// etc ...
```
To check the result :
```go
if result.Valid() {
fmt.Printf("The document is valid\n")
} else {
fmt.Printf("The document is not valid. see errors :\n")
for _, err := range result.Errors() {
// Err implements the ResultError interface
fmt.Printf("- %s\n", err)
}
}
```
## Working with Errors
The library handles string error codes which you can customize by creating your own gojsonschema.locale and setting it
```go
gojsonschema.Locale = YourCustomLocale{}
```
However, each error contains additional contextual information.
**err.Type()**: *string* Returns the "type" of error that occurred. Note you can also type check. See below
Note: An error of RequiredType has an err.Type() return value of "required"
"required": RequiredError
"invalid_type": InvalidTypeError
"number_any_of": NumberAnyOfError
"number_one_of": NumberOneOfError
"number_all_of": NumberAllOfError
"number_not": NumberNotError
"missing_dependency": MissingDependencyError
"internal": InternalError
"enum": EnumError
"array_no_additional_items": ArrayNoAdditionalItemsError
"array_min_items": ArrayMinItemsError
"array_max_items": ArrayMaxItemsError
"unique": ItemsMustBeUniqueError
"array_min_properties": ArrayMinPropertiesError
"array_max_properties": ArrayMaxPropertiesError
"additional_property_not_allowed": AdditionalPropertyNotAllowedError
"invalid_property_pattern": InvalidPropertyPatternError
"string_gte": StringLengthGTEError
"string_lte": StringLengthLTEError
"pattern": DoesNotMatchPatternError
"multiple_of": MultipleOfError
"number_gte": NumberGTEError
"number_gt": NumberGTError
"number_lte": NumberLTEError
"number_lt": NumberLTError
**err.Value()**: *interface{}* Returns the value given
**err.Context()**: *gojsonschema.jsonContext* Returns the context. This has a String() method that will print something like this: (root).firstName
**err.Field()**: *string* Returns the fieldname in the format firstName, or for embedded properties, person.firstName. This returns the same as the String() method on *err.Context()* but removes the (root). prefix.
**err.Description()**: *string* The error description. This is based on the locale you are using. See the beginning of this section for overwriting the locale with a custom implementation.
**err.Details()**: *gojsonschema.ErrorDetails* Returns a map[string]interface{} of additional error details specific to the error. For example, GTE errors will have a "min" value, LTE will have a "max" value. See errors.go for a full description of all the error details. Every error always contains a "field" key that holds the value of *err.Field()*
Note in most cases, the err.Details() will be used to generate replacement strings in your locales, and not used directly. These strings follow the text/template format i.e.
```
{{.field}} must be greater than or equal to {{.min}}
```
The library allows you to specify custom template functions, should you require more complex error message handling.
```go
gojsonschema.ErrorTemplateFuncs = map[string]interface{}{
"allcaps": func(s string) string {
return strings.ToUpper(s)
},
}
```
Given the above definition, you can use the custom function `"allcaps"` in your localization templates:
```
{{allcaps .field}} must be greater than or equal to {{.min}}
```
The above error message would then be rendered with the `field` value in capital letters. For example:
```
"PASSWORD must be greater than or equal to 8"
```
Learn more about what types of template functions you can use in `ErrorTemplateFuncs` by referring to Go's [text/template FuncMap](https://golang.org/pkg/text/template/#FuncMap) type.
## Formats
JSON Schema allows for optional "format" property to validate instances against well-known formats. gojsonschema ships with all of the formats defined in the spec that you can use like this:
````json
{"type": "string", "format": "email"}
````
Available formats: date-time, hostname, email, ipv4, ipv6, uri, uri-reference.
For repetitive or more complex formats, you can create custom format checkers and add them to gojsonschema like this:
```go
// Define the format checker
type RoleFormatChecker struct {}
// Ensure it meets the gojsonschema.FormatChecker interface
func (f RoleFormatChecker) IsFormat(input interface{}) bool {
asString, ok := input.(string)
if ok == false {
return false
}
return strings.HasPrefix("ROLE_", asString)
}
// Add it to the library
gojsonschema.FormatCheckers.Add("role", RoleFormatChecker{})
````
Now to use in your json schema:
````json
{"type": "string", "format": "role"}
````
Another example would be to check if the provided integer matches an id on database:
JSON schema:
```json
{"type": "integer", "format": "ValidUserId"}
```
```go
// Define the format checker
type ValidUserIdFormatChecker struct {}
// Ensure it meets the gojsonschema.FormatChecker interface
func (f ValidUserIdFormatChecker) IsFormat(input interface{}) bool {
asFloat64, ok := input.(float64) // Numbers are always float64 here
if ok == false {
return false
}
// XXX
// do the magic on the database looking for the int(asFloat64)
return true
}
// Add it to the library
gojsonschema.FormatCheckers.Add("ValidUserId", ValidUserIdFormatChecker{})
````
## Uses
gojsonschema uses the following test suite :
