SqlLite

Frew Cen — 2013-05-25T12:09:29

Matthijs instructed me (very carefuly) to edit installation to contain 
SqlLite. It's 32-bit version, it should run everywhere.

So it works.

Upgrade to VS 2012?

Trivalik Trivalik — 2013-05-24T15:38:05

Whats the plans?

I was testing by my self. I could build with install.bat (without arguments) the hole devkit. I have install VsSdk with a trick.

Only the Task that should start the setup is not working. How is it desired?

Also is the Inno script probably not complete from my side.

SQLite

Matthijs ter Woord — 2013-05-22T13:01:27

What's state on SQLite?

What tools are there to be converted to .exe's?

FAT Support

atom_ap — 2013-05-04T11:48:47

I want to know who is working on FAT Write support, And FAT reading support (which is not fully developed, As it is only able to read root directory)

And such undeveloped FAT is not so much useful for cosmos users

Primary and logical volume

atom_ap — 2013-05-04T11:40:34

Currently Cosmos is using Partition Class... Which defines only primary partition...And We are currently only achieved detecting Primary partition...But i am thinking that we should have capacity of detecting logical volume...

As it is not important for now...But i want to know who is interested in implementing logical volume...

We have to divide partition class into two classes 
1) Primary Partition
2) Logical Partition

Send your suggestion here :)

Another bug on build...

Henry Wright — 2013-04-29T18:55:26

I get this when building my OS but not when building Cosmos. It's strange.
Error7Could not load file or assembly 'EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

First Changes

melikescheese — 2013-04-28T08:17:59

I would like to commit my first source changes which are:

+ Installer now installs SQLite libraries fixing the library not found bug when installed.
+ Folder layout .html explaining the folder structure.

That is all, not any major changes though.

Cosmos Builder VMWare check for uninstaller as well as install registry key?

melikescheese — 2013-04-27T15:34:41

For some reason on my computer the VMWare player key that the builder looks for on install is not there. 

But the key in the check for uninstaller area is fine. 

Is this an issue with VMWare in general or just my install?

Would it be OK to have the builder check for the uninstaller key as well as the install key in the registry just in case?

ATA LBA48 support

Frew Cen — 2013-04-22T08:45:59

Hi all. I found out that in ATA PIO code there is only LBA28 support...
Does it have some special reason? I was thinking of adding there code which
detects if address passed as Int64 exceeds 2^28 - if yes, it can use LBA48.
The problem of LBA28 can occur on larger drives using FAT32...
Also, ATA code uses polling. What about interrupts? I can see they're
defaultly turned off by constructor.

FYI: MMTk (GC toolkit) now available on NuGet

lost — 2013-04-22T06:28:13

Hey guys,

In my spare time I'm trying to implement my own CLR-based OS. As a part of
the project, I've translated Memory Management Toolkit library from Jikes
Research VM to C#, and packaged it as a fancy NuGet package. Just thought,
that this might be an interesting option for you too.

Package on NuGet repository: MMTk <https://nuget.org/packages/MMTk/>
The project itself: https://bitbucket.org/lost/mmtk
License info (requested by mterwoord) is available here:

Best regards,

Questions about plugs

clearosdev — 2013-04-17T20:17:12

I am trying to make an internal assembler that works in the kernel for both cosmos and my project entity os framework. In the compiler right now how is plugs differ from all the other code that is converted from il to asm?

high(er) priority job

Matthijs ter Woord — 2013-04-17T16:20:36

Could someone look into replacing SQL Localdb with sqlite? (but without
losing the entity framework)

Presentation of a new comer

maldus0 — 2013-04-12T14:04:03

Hello everyone,
i'll try to present myself in a few sentences.

I'm a confirmed C# developper (since 7 years).
I've worked for a lot of big company (capgemini, Amadeus, Acoss (french social security),...) and developed some system skill aside.

For one of my customer i was in charge of a linux distribution specialized in clustered jobs.
For one other i develop a full P2P C# librairy. (i won't list all my experiences, if you want i can send you my resume instead) 
I also have some skills in neural net, DirectX programming (with or without XNA), network programming, system programming and web programming (mvc3/4,...)

I wanna join Cosmos project in order to fork it and develop an Hypervisor at the top (and integrated in) Cosmos in order to be able to span a virtual machine across several node.

If my profile sounds interesting for you, i think i can do some works on the fork that can be reused for Cosmos Core.

I'm open to every questions ! Feel free to ask more informations.

Best regards.

ps: Sorry for my poor english, i'm french.... (and sorry for my president too ... )

Latest patch on codeplex

Matthijs ter Woord — 2013-04-10T06:18:55

Can someone have a look at the patch for VS2012 support for cosmos?
Would be great to have VS2012 working (in .net 4.0 mode for now).
We should not however disable VS2010 support...

Hello everyone!

theuniqos — 2013-04-09T12:55:16

Hello everyone!

As requested via email, here are my interests...

I'm interested in improving Cosmos' reputation, helping to port it to mono, fixing simple bugs and issues as well as documentation.

In regards to what I've previously said, is there any thing that I could do to help with Cosmos' journey?

Cheers

Work on X#...

Frew Cen — 2013-03-28T08:40:09

Ok. On the beginning of this week I spent some time with Kudzu asking 
what does the X# support (and what doesn't).
While we were skyping (or skypeing? who knows?), I made small list of 
features which should be done. Because I have some free time, I want to 
ask what can I implement and in some cases how can I implement it.
So.... the list:

  * support for binary+octal constants - I was thinking of using zero
    prefix for octal and b prefix/postfix for binary
  * creating stack frames - I read that it was in plans... But I think
    that there should be still some way for creating functions without
    stack frames (for example __declspec(naked) in VC)
      o BTW there are also interrupts. Is there some difference except
        returning via IRET?
  * local variables - don't see it really needed... but still when stack
    frames..... ??????
  * supporting new combinations of ports/values
      o currently, there is only Port[DX] = AL - intel, intel, intel.....
      o but we can save registers we will work with, move port to DX,
        value to (E)A(X/L) and then reload register values from stack

  * parametrized calls are already supported - yes, it's true
  * setting code origin from X# - currently, you have to use native asm
    block (! org)
  * position macros - maybe similar to nasm's... they are needed ($ -
    actual pos, $$ start pos)
  * comments on the same line as the code (EAX = EBX // this is comment
    like in C)

That's all. What do you think? What needs to be added? How do you plan it?

Userkit release cycle and related stuffs

Joshua Beitler — 2013-03-14T18:35:08

I think that we should try to get a regular release cycle going for
the user-kit.  I also think that we should have a better version
numbering system than just "Userkit <source checkin # here>".
Personally, I think something like <year>.<month>.<day> would be
fairly good for releases.  This would be much easier to type and
remember.

Clearosdev: alternative debugger?

Matthijs ter Woord — 2013-03-14T07:11:39

What's you plans on that alternative debugger? To whom is it targetted?

A Simple Mistake in Write Block...

atom_ap — 2013-03-14T06:25:49

During Surfing the code of COSMOS, I had a mistake in block device

...Mistake Code
public override void WriteBlock(UInt64 aBlockNo, UInt32 aBlockCount, byte[] aData)
        {
            CheckDataSize(aData, 1);
            SelectSector(aBlockNo, 1); 
                        .........................

...Correct Code
public override void WriteBlock(UInt64 aBlockNo, UInt32 aBlockCount, byte[] aData)
        {
            CheckDataSize(aData, aBlockCount);
            SelectSector(aBlockNo, aBlockCount); 
                        .........................

Due to this we cant write more than 1U block...As it throw Invalid Data Size...

Requesting to join cosmos

clearosdev — 2013-03-11T12:11:31

I have requested to join cosmos. I have 3 years of c# behind me and I as know c++, vb, lua and python. I have my own cosmos os project at sacos.codeplex.com. I should be able to put in at least 3 hours a week this project helping it grow.
