FAT implentation

I think I've narrowed down the issue in the FAT implementation. The compiler looks like it is working properly. I have more testing to do, but I think the issue is in the FatStream and FatFileSystem classes.

Cosmos Debugger work

I just checked in a changeset which adds some functionality to the debugger. Fields (primitive types only for now) can be inspected in the locals and watches window. They are currently read-only.

Stack Corruption bug and Compiler changes

As you all might know, our current FAT implementation is hitting a stack corruption bug. Fixing this bug led us to discover a large design flaw in our current compiler. I'm working on fixing that. THe first part of the changes are now enabled in current devkit. This means however that you may potentially run into exception when building. When you encounter any, please let me know...

Source Tree Changes

We are cleaning the source tree.

Several changes will be noted, but one is that User projects have been 
removed from the main SLN. They will be moved to a user dir. If you are 
an active user, please add them back to the SLN later today until we get 
a SLN generation tool.

test for inno setup required, changes related to VS Express 2014

I made a change in inno setup, now i need tester for VS express and also VS Pro/Premium/Ultimate.

I checked VS Express in virtual machine by my self. but retest by guys which had the issue would be nice.

I removed many keys, which are not used anymore.


I am also not sure about the Wow6432Node, if inno setup handle it also without this.

Current state and how to get moving again

When seeing the amount of discussions on codeplex and yahoo, there's lots of interest in Cosmos.

Currently, Cosmos is moving at a very slow pace. We have lots of smaller and not so complicated tasks. (Of course, we have more complicated and bigger ones as well, if you feel like it....) Judging by the discussions, both on cosmos-dev as on codeplex, I really think many people working on serious stuff over there, could help up as a project move forward quite a bit by spending some time on some of the important tasks laid out. In the past, people have asked and complained about lack of certain features (GC, VGA, networking, threading, dynamic loading, etc, etc, etc), but right now, we're still in the babysteps-stage. Working on interesting stuff l ike dynamic loading right now, would be like putting tail-lights on a car, which doesn't even have axels yet.
If we could get some help on that, we can get Cosmos moving fast!

Here's a short list of the current higher-priority items:
- Debugger - Assembly stepping. This is a must for hunting the compiler bug
- Debugger - Assembly step tracing. This would make the compiler bug hunt a 30 minute job.
- Compiler bug: Some kind of stack corruption
- FAT (blocked by compiler bug)
- Let's make a list of common mistakes/known issues and workarounds. Put on it: Builder tool uses a Scheduled task to circumvent the UAC window everytime. Sometimes it wont work, just delete the task and it'll be created again.

If you're interested in helping out, need more info, or unsure you could help, please respond and we'll get you started.

Current state: Compiler

It's easy to say this one: Compiler is way too slow.

This should be a doable task for almost anyone to put in some logging code in the compiler task, to see where its slow. Compiling takes like a minute on a fast i7/16GB ram/Velociraptor machine. This used to be 15-25 seconds...

Please before making any performance improvements, please make sure what parts are slow, and discuss on the list before making any changes to the compiler.
Anyone taking this task?
