[Mono-dev] Bug 10784

[Jamie Venning]

Good Morning.

Bug 10784 (
https://bugzilla.xamarin.com/show_bug.cgi?format=multiple&id=10784) is a
major blocker for me, and a big obstacle for larger applications moving
from .NET to Mono. Because I need this fixed, I am prepared to fix it
myself.

I'm wondering if anyone knowledgeable in this area could answer these few,
short questions just to confirm a few things.

Removing the offending assertion from class.c, and running generated test
cases that previously triggered it, I did not notice any incorrect
behaviour in terms of reflection, the 'is' operator failing, or the wrong
implementation of functions being used. Is there anywhere that I should be
looking in particular or any particular type of tests I can use to expose
an underlying fault that removing this assertion causes?

Is it possible that this assertion is vestigial or unnecessary?

Re: [Mono-dev] Is property?

[Greg Young]

Maybe explaining the use case a bit more is worthwhile. I am running
in the context of the profiling API. In many bits of code it is
prohibitively expensive (and not at all valuable) to look at
getters/setters. Even doing a hash lookup in them adds significant
overhead (think code that tends to use getters/setters for all field
access or code doing bunches of serialization).

I am looking for a way to fail fast on them, getting the name and
checking would be more expensive than the hash lookup.

Is there an easy way to test METHOD_ATTRIBUTE_SPECIAL_NAME for a MonoMethod *?

Hi Greg,

I'm afraid there's no exact flag for that. The best approximation
would be to test that it is flagged METHOD_ATTRIBUTE_SPECIAL_NAME, and
that its name starts with "set_" or "get_".

Short of that, you'll need to iterate over the properties of the class
and check that one of its methods points to your MonoMethod.

[Mono-dev] Is property?

[Greg Young]

How can you figure out if a method is a property from a MonoMethod *?

I have poked around looking for this for an hour or so and can't find it.

Cheers,

Greg
