info.context question about dokan-dotnet HOT 11 CLOSED

Hi @maurosampietro ,

it is right, the context should be the same between CreateFile and CloseFile.

You should also know that there could be different context for the same file. The system is offen going to call CreateFile a multiple time in the same moment. Therefore you will have one new context for each request.
Ex:

#1 CreateFile \test.txt
#2 CreateFile \test.txt
#1 Write 
#2 Lock
#1 CloseFile
#2 CloseFile

I create a new WriteStream every time CreateFile w/ FileMode.CreateNew is called. How do you usually manage this situation to avoid 'file already in use' exceptions?

(I never get Lock function called but it may not be a problem now)

You have to handle sharing mode with https://msdn.microsoft.com/fr-fr/library/system.io.fileshare%28v=vs.110%29.aspx at open.

So i'm already doing the right way :) thank you!

I'm sorry to bore you but i have a few other question in order to complete my file system...

Suppose i want to copy a file i have on my desktop called 'file.dat' to my volume. The final destination path is '\subdir1\subdir2'. I open explorer browse to this destination folder and paste my file.dat.

In debug i see CreateFile is called w/ FIleMode.CreateNew parameter but the path is missing the actual name of the file: i receive ''\subdir1\subdir2' but i expected '\subdir1\subdir2\file.dat' in order to properly create the file. The operation fails telling me there's not enough space. What's happening here?

If i copy from code the same file in my unit test, i correctly receive '\subdir1\subdir2\file.dat' and I am able to create the file.

At first the device open the folder ''\subdir1\subdir2' to be sure that it exist and only after it is going to call you with '\subdir1\subdir2\file.dat'.

Do you check if the request is made for a directory ?

I write on Console any request of create file. I don't seem to receive the proper '\subdir1\subdir2\file.dat' request. I check for directories.

Humm so there should be something wrong in your implementation before this call.
It is pretty hard for me to give you advice at this point 😢

Did you start your project by editing the mirror ?

from dokan-dotnet.

You seem quite sure it's something related to my implementation so I'll will investigate some more. Back to you if this persists. thank you.

@maurosampietro You can pass in a ConsoleLogger when doing the mount. So you don't need to log your self.

@maurosampietro do you still have issues or I can close the ticket ?
