[Mono-devel-list] Improved and fixed mcs /doc patch

[Atsushi Eno]

Hello,

Here I put the revised patch for mcs /doc support. It fixes
some problems raised by Marek (thanks!) and added warning
implementations. There are some changes made after the last
patch:

	- It now fills document info after DefineTypes().
	- It now checks <param> and <include> elements.
	- It now handles child enums and types in TypeContainer.

There are still remaining to-do tasks wrt this functionality:

	- comments on invalid language elements are not detected
	- cref resolution and check are not done

Tests are attached, but as for document comparison, not yet.

Comments are appreciated.

Here I reply to the latest comments from Marek;

* commented items

- 1. Error 2006 should be more explanatory.
	I wonder if I should really fix it. The message format is
	the same as other similar error formats.

- 2. test WarningLevel.
	fixed.

- 3. Use String.Format() instead of "+".
	Fixed.

Right. Fixed. BTW, I could not use neither GetSignatureForError()
nor TypeBuilder.CSharpName() since it replaces some types with C#
keywords e.g. System.Int32 to int. I just replaced "+" with ".".

- 4. Use const for "M:" and "P:" and so on.
	Sure it might be desirable, but where do you put them?
	I grepped "const string" and got only 3 results.

- 5. "params" (ArrayParameter) causes incorrect method documentation.
	fixed.

- 6. Don't call FixupDocument() before defining types.
	It was just for performance wise. Originally it was almost
	the end of the compile. Now it is placed after DefineTypes().

If it is unsafe to handle documents before all DefineTypes() finish,
then reusing them still does not sound safe.


* Warnings and errors:

- 1569, 1570, 1571, 1572, 1573, 1589, 1590, 1592: done
- 1591: mostly done (method signature incomplete)
- 1574, 1580, 1581, 1584: not done (cref)
- 1587, 1588: a little done (comments on invalid language elements)

Thanks,
Atsushi Eno
