9 years agoMerge: Sys is top
Jean Privat [Fri, 10 Apr 2015 15:19:40 +0000 (22:19 +0700)]
Merge: Sys is top

And when I say *top* I mean *great*. But I also mean *top* in fact.

The idea is to move the top-level methods (those defined outside classes) from Object to Sys.
While this is a cosmetic move, it has a lot of benefits:

* top-level methods get a real meaningful receiver: the current system. It is meaningful both on the declaration side and the call side.
* no more need to distinguish the concept of top-level methods with their rules and semantic, so this simplify the language with one less thing (almost, see bellow)
* self is now usable in top-level methods, not that useful now because it is `sys`, a singleton, but this allow some kind of inheritance if you add super-classes to Sys.
* no more name conflicts between a standard class method and a top-level method
* no more useless slots in table of classes for crazy methods defined in Object and never redefined
* close #461 and close #1081 by making them irrelevant
* Let us see a bright future where the singleton Sys become a multiton and allow specific isolation of computation. Specific Sys will then be active objects (threads, computation node, actors, whatever) isolated with their own specific cloud of objects and efficient lock-less concurrency, dedicated memory model (realtime?), and why not transparent distribution

There is still two drawbacks

* what is the status of `sys` that represent the current `Sys`? I hard-coded it to stay a method in Object. One way to solve the probem is to make it a keyword (like `self`)
* when doing `foo(x)`, first this tries `self.foo(x)` then `sys.foo(x)` thus this is some additional rule of the language.

Merge: new `with` statement

Introduce the `with` statement that is analogous to the `with` of Python or the `uning` of C#.

   x.work
end
~~~

That is equivalent with

~~~nit
do
   var x = something
   x.start
   x.work
   x.finish
end
~~~

Note that an alternative syntax, without the local variable exists:

~~~nit
with something do
   work
end
~~~

that is used when we want some automatic control or whatever. Eg resource allocation or critical section.

~~~nit
do
   var tmp = something
   tmp.start
   work
   tmp.stop
end
~~~

Most real-world examples could be

~~~nit
with file = path.create do
   file.write("Bla")
end
~~~

and

~~~nit
with a_mutex do
   work
end
~~~

## Names

I reused the `finish` method from Iterator.
I introduced the antonym `start` for the other side.

Note that the `start` is important because it helps the object to know it has to prepare itself for a `finish`.

I did not introduce an interface, mainly because I have no idea for a name. C# names it `IDisposable` and the `finish` method is called `Dispose`. There is no `start` because C# designers are lunatic sometime.

In python there is no interface (obviously) and the method are called
`__enter__` and `__exit__` because Python likes identifiers that resemble words eaten by boas.
Note that the returned variable is not the original expression but the result of `__enter__`.
With the Python semantic, but the Nit syntax, the first example will be equivalent to

~~~nit
do
   var tmp = something
   var x = tmp.start
   x.work
   x.finish
end
~~~

I am not sure of the benefits of the additional complexity, but the the more I thing about it the more I think this could be useful, ex for the control case the `start` can return the handler to `finish`.

The issue is that proposed syntax: `with x = something` does not make sense (because `tmp=something` and `x=tmp.start`) thus should be replaced with something else; Python uses `with something as x:` that we can reuse but I do not want because it is ugly.

An other alternative I tough of was to reuse the `for` keyword. but It is convoluted.
The two previous real world examples will then be

~~~nit
for file = path.create do
   file.write("Bla")
end
~~~

and

~~~nit
for a_mutex do
   work

9 years agoMerge: Not null types
Jean Privat [Wed, 8 Apr 2015 01:01:49 +0000 (08:01 +0700)]
Merge: Not null types

In order to fix #86 and #1238 some preliminary work to solve remaining issues with the type system is needed. This PR is a step toward this goal.

This introduce not-null types, that is a modifier to indicate that a type cannot contain null.
Basically, this new modifier is almost useless because it is the semantic of all the types (except obviously null and nullable things). Except in one case: when one adapts a formal type whose bound is nullable.

Before the PR, the semantic was the following

~~~nit
class A[E: nullable Object]
   fun foo(e: E, o: nullable Object) do
      var o2 = o.as(not null) # the static type of o2 is `Object`
      print o2 # OK
      var e2 = e.as(not null) # the static type of e2 is still `E` because there is no `nullable` to remove
      print e2 # Error: expected Object, got E
   end
end
~~~

Obviously, the issue was not that important because people managed to program complex things in Nit and I do not remember getting some complain about that particular issue. For the rare cases of this unexpected behavior, a workaround was possible: to cast on the non-nullable bound

~~~nit
   var e2 = e.as(Object)
   print e2 # OK
~~~

Nevertheless, the behavior was still buggy since type information was lost and not POLA. Moreover, `!= null` and `or else` did not have a workaround.

So, this PR introduces a special new type-modifier for this case so that everything become sensible.

~~~nit
      var e2 = e.as(not null) # the static type of e2 is now `not null E`
      print e2 # OK
~~~

Moreover, a lot of local refactorisation was done in model.nit and typing.nit to clean and harmonize the code. So that independently of the new notnull modifier, the code is cleaner, some bugs where removed and some small features added, especially the detection of useless `or else`.

Last, but not least, the `not null` thing is only an internal modifier and is not usable as a syntactic type construction (the grammar and the AST is unchanged); `not null` can however be shown to the programmer in messages.

~~~nit
      var e2 = e.as(not null) # the static type of e2 is now `not null E`
      var e3 = e2.as(not null) # << Warning: expression is not null, since it is a `not null E` >>
~~~

I could easily add `not null` as a specific syntactic construction since everything internally is ready. but 1. does this worth it?. 2. I do not want to conflict with #1243 that also change the grammar.
As an example, is it useful to write the following? (currently refused but very easy to add after this PR)

~~~nit
class A[E: nullable Object]
   fun foo(e: not null E): not null E do
      var x = e.to_s # no null pointer exception
      # ...
      return e
   end
end

var a = new A[nullable Int]
var i = a.foo(5)

Merge: Improve checking of virtual types

This PR does 2 things to avoid runtime errors during nitc. Invalid programs that crashed the compiler now display errors messages.

* improve the static detection of loops in virtual types.
* consider types in the signatures of properties to be fragile since they contains potentially bad virtual types.

If merged with #1241 then nitpick can process the whole tests directory without crashing (impressive, since there is 1584 border-case files).
~~~
$ ./nitpick ../tests/*.nit ../tests/alt/*.nit -I ../lib/standard/ -I ../lib/standard/collection/
[... lots of errors ...]

Merge: Robust keep-going

Detection and resolution of crashes or irrelevant error messages with tools that keeps going (eg. nitpick).

Historically, the compiler just exited at the end on a step when an error occured. The ToolContext#keep_going flag disable this automatic exit and was introduced for tool that are expected to be launched on broken code: nitpick and nitlight. However most parts of the code expected that:

* the previous steps where completed successfully, and expected information where available and correct.
* they are that special important snowflake can just exit the whole program when they are unhappy.

These rules can make sense for a compiler but are to strict for most SE tools that need to work (or continue working) when some random module contain an error.
Thus this PR improve the robustness of various parts of the code for the keep-going case so that we do not exit or crash before having processed all the modules.

With this PR, the following command does not crash anymore:

~~~
$ nitpick `nitls -rps ../lib ../contrib ../examples`
[...]
Errors: 10. Warnings: 31.
~~~

Note that `nitpick ../tests` still crashes. There is ugly errors hard to recover from in this directory.

Maybe, one day most of the tools can be made keep going by default.
