Re: [ros-dev] Ros-dev Digest, Vol 145, Issue 16

by Love Nystrom

Agreed.. When the assignment and assert are separated by a call of X distance, the assert is certainly warranted. Just not as it stands in ke_x.h Perhaps you could factorize as suggested, Dmitri?

Re: [ros-dev] [ros-diffs] [dchapyshev] 72787: [NTOSKRNL] Remove unneeded sanity checks

by Alex Ionescu

Rationale is simple: The real headers contain a KeEnterCriticalRegionThread function, which has this assert, and a KeEnterCriticalRegion function, which calls that function with KeGetCurrentThread() at input. This is an optimization such that if you already have the current thread of interest somewhere, you can call KeEnterCriticalRegionThread and avoid reading from FS or GS again. ReactOS combines these two functions in one, and as such the ASSERT appears pointless. Factoring the functions would've been the correct approach -- not removing the ASSERT.

Re: [ros-dev] [ros-diffs] [dchapyshev] 72787: [NTOSKRNL] Remove unneeded sanity checks

by Love Nystrom

I don't want to trod on anyone's tail, but assigning _Thread = KeGetCurrentThread(), and then asserting _Thread == KeGetCurrentThread() on the next line does seem excessively myopic, yes ? Unless you expect KeGetCurrentThread() to be fubar and return rand(), in which case the assert should be removed when KeGetCurrentThread() gets it's head on straight. As to the talent, or lack thereof, of MS programmers, we might talk about it if we ever have a table with some beer on it between us. They're not *all* wrong.. no ;) L.

There are no disadvantages. Someone though it would be fun to remove useful assertions because they don't really understand them.
