Developers corner This page is for developers who are interested in working on umlwin32.
This page is in no way complete and I will keep updating as I think of things
to put. It you want to work on any of these or anything else related to
umlwin32 drop me a note at ckudige "at" users dot sourceforge dot net or post a message in uml-devel
mailing list.
-
Implementing signal support.
-
Testing bash, ksh, simple commands like tar/gzip etc
-
Optimise ubd block access which is quite slow on windows.
-
Implement win32 mmap() and unmap() on 4K boundaries: This is the biggest
stumbling block. I havent had much luck with this. Standard win32 APIs
(MapViewOfSection, etc.) work on 64K boundaries. The same seems to be
true for native APIs too (NtMapViewOfSection and ZwMapViewOfSection).
Funnily, I see that we can map at 4K boundaries with the physical memory
device (\Devices\PhysicalMemory). This might be the clue we need to follow
for fixing this problem.
-
An important task - To create a platform dependant layer and move
win32 specific things out there. Make sure that the code compile
for both Linux and Windows properly.
-
Test/debug as many system calls as possible. We can use Python for
this.
-
Create a boot-disk with init/getty/login etc.
-
Merge with the latest UML patch so that we are up-to-date.
-
Move over to win32 API instead of Cygwin API. This should make things
cleaner and faster.
-
There are a lot of limitations outlined in the Technical Details page.
Eventually we need to overcome these limitations and implement them more
optimally.
