7 years agoMerge: proposal: lib/config
Jean Privat [Mon, 5 Dec 2016 20:53:32 +0000 (15:53 -0500)]
Merge: proposal: lib/config

We often need basic option handling in our app.

Here a minimalist proposal that covers the basics:
* options holder
* default values
* loading options from ini file

Extract from doc:

# Configuration options for nit tools and apps

This module provides basic services for options handling in your nit programs.

## Basic configuration holder

The `Config` class can be used as a simple option holder and processor:

~~~nit
import config

# Create a new config option
var opt_my = new OptionString("My option", "--my")

# Create the config and add the option
var config = new Config
config.add_option(opt_my)

# Parse the program arguments, usually `args`
config.parse_options(["--my", "myOption", "arg1", "arg2"])

# Access the options and args
assert opt_my.value == "myOption"
assert config.args == ["arg1", "arg2"]
~~~

## Custom configuration class

Instead of using basic `Config` instances, it is better to define new sublcasses
to store options and define custom services.

~~~nit
import config

class MyConfig
super Config

var opt_my = new OptionString("My option", "--my")

init do
super
tool_description = "Usage: MyExample [OPTION]... [ARGS]..."
add_option(opt_my)
end

fun my: String do return opt_my.value or else "Default value"
end

var config = new MyConfig
config.parse_options(["--my", "myOption", "arg1", "arg2"])

assert config.my == "myOption"
assert config.args == ["arg1", "arg2"]
~~~

We define the `my` method to provide an elegant shortcut to `opt_my.value`
and define the default value if the option was not set by the user.

The `tool_description` attribute is used to set the `usage` header printed when
the user request the `help` message.

~~~nit
config.parse_options(["-h"])
if config.help then
config.usage
exit 0
end
~~~

This will display the tool usage like this:

~~~raw
Usage: MyExample [OPTION]... [ARGS]...
 -h, --help   Show this help message
 --my         My option
~~~

## Configuration with `ini` file

The `IniConfig` class provides an easy way to link your configuration to an ini
file.

~~~nit
class MyIniConfig
super IniConfig

var opt_my = new OptionString("My option", "--my")

init do
super
tool_description = "Usage: MyExample [OPTION]... [ARGS]..."
opts.add_option(opt_my)
end

fun my: String do return opt_my.value or else ini["my"] or else "Default"
end
~~~

This time, we define the `my` method to return the option value or the ini
if no option was passed. Finally, if no ini value can be found, we return the
default value.

By default, `IniConfig` looks at a `config.ini` file in the execution directory.
This can be overrided in multiple ways.

First by the app user by setting the `--config` option:

~~~nit
var config = new MyIniConfig
config.parse_options(["--config", "my_config.ini"])

assert config.config_file == "my_config.ini"
~~~

Default config file can also be changed by the library client through the
`default_config_file` attribute:

~~~nit
config = new MyIniConfig
config.default_config_file = "my_config.ini"
config.parse_options(["arg"])

assert config.config_file == "my_config.ini"
~~~

Or by the library developper in the custom config class:

~~~nit
class MyCustomIniConfig
super IniConfig

redef var default_config_file = "my_config.ini"
end

var config = new MyCustomIniConfig
config.parse_options(["arg"])

assert config.config_file == "my_config.ini"
~~~

7 years agoMerge: serialization: subtype check attributes & serialize part of the metamodel
Jean Privat [Mon, 24 Oct 2016 18:48:10 +0000 (14:48 -0400)]
Merge: serialization: subtype check attributes & serialize part of the metamodel

This PR is a bit out of the ordinary, it tackles 2 issues with serialization:

1. Avoid deserializing unwanted types to fix a security hole where a refined attribute setter could be abused to cause side effects in the running program.

   The solution inserts 2 checks in the deserialization process, for JSON only:

   1. Check the dynamic type of the Nit object to create from a JSON object against the static type of the attribute. It is created and deserialized only if the dynamic type is a subtype of the static type. This check is activated by default, it can be turned off for some rare use case.

   2. A whitelist lists the accepted dynamic types to deserialize. It can add an extra level of security above the subtype check, or manually replace it when it can't be used. If the whitelist is empty, this check is disabled, the default.

   Pseudo-code algo:
   ~~~
   for name, value in json_object_as_hash_map do
       if value isa json_object_as_hash_map do
           # Existing: find the dynamic type from __class, class_name_heuristic or fallbacks on the static type
           var dynamic_type = heuristic_dynamic_type(value)

           # New
           check whitelist.has(dynamic_type)
           check dynamic_type isa static_type
       end
   end
   ~~~

   Note that attributes typed by `Object` still accept anything (as expected). But there is also a security hole with attributes typed by a virtual type bound to `Object`. We don't have runtime access to the precise type of the virtual attribute so we always use the upper bound `Object`. So `Array` and the like are still a vulnerable point.

2. Ask for a specific static type at serialization while preserving polymorphism.

   The solution adds an argument `static_type` to `JsonDeserializer::deserialize` to ask for a specific type. The deserialized object will be a subclass of `static_type`, or `null` on error.

   This should be preferred to calling directly `from_deserializer` as it allows for subclasses and return null on fatal errors.

   ~~~
   var engine = new JsonDeserializer("""{"item": 4}""")
   var obj = engine.deserialize("Ref[Int]")
   assert engine.errors.not_empty
   assert obj isa Ref[Int]
   ~~~

These features rely on a new intern service `class_inheritance_metamodel_json` (I'm not convinced by the name but at least it is private). This method returns a `POSet[String]` serialized to JSON representing the inheritance graph of the running program. The compiler stores the JSON string in the generated C code, it takes about 200kb for a small program.

It would be pretty easy to add other services to read the metamodel, as needed. However, there is a strong coupling between the JsonDeserializer and `class_inheritance_metamodel_json`, this could be solved by adding a few modules with abstract services.

Future work:
* Do the same in the binary serialization engine.
* Move the metamodel services out of the `json` package.
* With a runtime access to the precise type of virtual types (`V.class_name`),
  fix hole with attributes bound to a `nullable Object` static type.
* Do a full subtype check, not only subclass check (for generic classes).
* Use full qualified names in the serialized metamodel to avoid name conflicts.

@ppepos Did I correctly isolate the security issue? There is an example of the vulnerability in the test.

Merge: nitrestful: rename resources and restrict HTTP methods

The `restful` annotation makes a method accessible by HTTP requests. It saves a ton of boilerplate code by taking care of simple routes, deserializing the arguments and handling error management. It is already in use by the Benitlux server.

This PR adds documentation for the `restful` annotation and updates the example. It also improves the `restful` annotations by adding the support for two kind of arguments:

* String literals rename or add an alias for the HTTP resource. By default, the name of the HTTP resource is the name of the `restful` method. The first string literal replaces the default name, while additional strings literals add aliases.

* Ids such as `GET`, `POST`, `PUT` and `DELETE` restrict which HTTP methods are accepted. By default, all HTTP methods are accepted.

Once #2311 is merged, we will be able to update `nitrestful` to better support plain JSON objects as input.
