Dev blogs

by Murphy, Ged (Bolton)

I'd quite like to see the blog page integrated into the site and made to look pretty. I also think it might entice devs to start using the thing. At the moment there is only about 4 people listed, and of those only Alex every actually uses it. Would developers make an effort to start blogging if it was 'spruced up' and integrated? If not, I think it should be removed as it looks a bit pitiful as it is and gives the impression not much is going on (which is obviously not the case) It doesn't always have to be development related stuff in there. Anything interesting draws a crowd.

Strategy for invalid parameters

by M Bealby

I was just taking a look at some ReactOS code this evening and it got me thinking about what our general strategy for handling invalid parameters is. For example, in kernel32.dll there is a function DebugBreakProcess. This function takes one parameter, a process handle. This parameter is passed through the following list of functions unchecked by any of them, until the final one will return a failure... DebugBreakProcess DbgUiIssueRemoteBreakIn RtlCreateUserThread RtlpCreateUserStack ZwAllocateVirtualMemory ObReferenceObjectByHandle Now I know this isn't a security vulnerability, which is what I was originally looking for, but it did make me think of the question of where should bounds checking be added? In this example, the process handle must be a value greater than zero. Should this simple check be added to DebugBreakProcess, or all of the above? Is there some sort of standard that everyone should work to? e.g. should all functions check their own parameters. Sure it might make it a little slower due to multiple checks but it would make ReactOS very robust. Any thoughts on this? Martin PS: Lack of activity recently had been due to uni. exams.

cmpxchg8b

by Ge van Geldorp

It seems the old binutils versions don't have a problem with "cmpxchg8b" but with "qword ptr". The patch below makes the code compile on older versions again. Any objections to committing it? I've created a bug 1264 for keeping track of the "no longer works on i486" issue.

Wininet

by Robert Shearman

Why is the ReactOS version of wininet out of sync with Wine? There have been a ton of fixes going into Wine in recent months that unfortunately ReactOS is missing out on. -- Rob Shearman

Adding "__cdecl" attributes doesn't make much sense for me. And winefile compiles without problems on MSVC since ages. Regards, Martin
