[MonoDevelop] About cyclic dependencies and more

["Andrés G. Aragoneses [ knocte ]]

Hello MonoDevelopers...

When translating MonoDevelop I noticed that there is a string warning
the user about the lacking feature of managing cyclic dependencies with
MonoDevelop. However, I have tried to make a cyclic dependency and
MonoDevelop has not warned me, and instead it has showed me the
following exception:

> Ocurrió una excepción: Exception has been thrown by the target of an invocation.
> 
> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> MonoDevelop.Projects.CyclicBuildOrderException: Exception of type MonoDevelop.Projects.CyclicBuildOrderException was thrown.

Is this the expected behaviour? Should I file a bug for that?

I have found this issue when working with the "MonoDevelop.mds" solution
file, from which I have found the following issues:


- When clicking on "Clean solution" after a compilation has been failed,
the following exception arised:

> Ocurrió una excepción: Object reference not set to an instance of an object
> 
> System.NullReferenceException: Object reference not set to an instance of an object

> in <0x0039a> MonoDevelop.Components.Commands.CommandManager:DispatchCommand (System.Object commandId, System.Object dataItem)


- The MonoDevelop.Documentation project depends on MonoDevelop.Projects,
which depends also on MonoDevelop.Documentation, so why is here this
cyclic dependency? Is desirable to fix the namespaces (adding one more
project, I wonder...) so as to remove it? I suppose yes, so as to be
able to make a self compilation of MonoDevelop inside MonoDevelop,
although I deduce that a whole build is not possible (yet?).

- When opening MonoDevelop.mds I have obtained a FileNotFound exception.
The fix is to replace "VBNetBinding.mds" by "VBNetBinding.mdp".

- Some files referenced in projects are not found (for example,
GettextCatalog.cs, but the one that exists is the same file ended wit
".cs.in"). I suppose this is because GettextCatalog.cs must be generated
from GettextCatalog.cs.in, am I right? Would it be possible to
pre-generate it before loading and working with the MonoDevelop.mds
solution? (BTW, the same happens with AssemblyInfo.cs <->
AssemblyInfo.cs.in in the same project:
Core/src/MonoDevelop.Core/MonoDevelop.Core.mdp .)

- It seems that the file Core/src/MonoDevelop.Core/MonoDevelop.Core.mds
is not used and the one that is referenced from Core.mds is
Core/src/MonoDevelop.Core/MonoDevelop.Core.mdp, so it should be safe to
delete it.

Regards and thanks in advance for any answers.
