by Thomas Faber

Hmm, my thought behind disabling this was more that this one test doesn't justify increasing our whole test run time by 10%.

Thank you for working on this hack (partial) removal! After all, having it only in the 1st stage is a win over having it enabled all the time.

You add parentheses to conform to coding style (our coding style guidelines do not require it) and on the other hand you convert a 2 line if statement into one line, which does not conform to our coding style?

You need to recompile NTVDM with WIN2K_COMPLIANT define if you want to be able to run it on win2k. In that case DisplayMessage uses a quite large enough buffer for its needs). If somebody knows an alternative to _vscwprintf that does the very same job, and which exists on Win2k, I would be happy to use it instead. Since _vscwprintf will do the whole work already anyway, you could as well directly print it into the static buffer. You could use _vsnwprintf or StringCbPrintfW, which internally uses the former, and use the result to decide whether the buffer was large enough. This will be more performant, since you only need to print once, when the buffer is large enough.

Re: [ros-dev] [ros-diffs] [tfaber] 65269: [FASTFAT] - VfatCleanupFile: do not dereference the FCB when closing the volume file object. ObDereferenceObject already causes an IRP_MJ_CLOSE request to be sent, which dereference...

by Thomas Faber

Oh... Jérôme, I only just saw that you added this in r65140... And my change does break the msi tests again. :\ Any idea what's going wrong here? I'm relatively certain my change is correct because vfatFCBInitializeCacheFromVolume takes one reference, and VfatCloseFile invoked via ObDereferenceObject will remove that reference again. So apparently we're leaking a directory reference somewhere else? :( Not sure if your previous investigation into this issue can provide any pointers. Otherwise I'll have to start digging for the leak all over again...

Re: [ros-dev] [ros-diffs] [jgardou] 65210: [NTOS/PS] - Do not leak a reference to the process object when setting quotas.

by Timo Kreuzer

Doesn't this change Windows behaviour? No, luckily it does not change *Windows* behaviour. It does not even change ReactOS behaviour, but only, because it was already broken before. Since MS implemented this function in an arbitrary and hard to comprehend way, we need to follow this pattern. This means, the function must not fail on process reference failure, unless certain conditions are met, otherwise we will fail with the wrong Status code. To fix the situation, we could remember the fact that the process couldn't be referenced (possibly by setting Process to NULL) and later check that after other checks were done. The alternative is referencing the process individually in each and every case, which will make the function even more huge and does not really help with it's readability. Or we can factor our each case and implement it as a separate function. It would add a lot of code duplication, but might help a bit with readability and maintainability.
