10 months ago I'm not even allowing such a thing will help you, the current code is setting the share_access="rwd" which is essentially trying to be as relaxed as possible when attempting to open the directory in case something else has or will open a new handle on that directory. Using rwd includes r inside the list of FILE_SHARE values used.
It sounds like the there is an existing handle on some directory in the tree, or the root dir itself. has been opened without the read share access itself so it cannot be opened again no matter what share_access value you specify.
Granted the file sharing stuff is complicated and I could have missed something but here is an example in PowerShell where you open two file handles, one with a more restricted file share of Read while the second handle is doing the rwd equivalent:
$path = 'C:\temp\test.txt'
New-Item $path -Value foo -ItemType File -Force
$fs1 = [System.IO.FileStream]::new($path, 'Open', 'Read', 'Read')
$fs2 = [System.IO.FileStream]::new($path, 'Open', 'Read', 'ReadWrite, Delete')
$fs1.Dispose()
$fs2.Dispose()Compare that to this example where the first file was opened without any share access rendering the next two attempts unable to open the handle regardless of the sharing option specified
$path = 'C:\temp\test.txt'
New-Item $path -Value foo -ItemType File -Force
# Opens handle with read access
$fs1 = [System.IO.FileStream]::new($path, 'Open', 'Read', 'None')
# Both fail with
# Exception calling ".ctor" with "4" argument(s): "The process cannot access the file 'C:\temp\test.txt' because it is
being used by another process."
[System.IO.FileStream]::new($path, 'Open', 'Read', 'Read')
[System.IO.FileStream]::new($path, 'Open', 'Read', 'ReadWrite, Delete')

Hi, it seems it is not possible to use kwarg
share_access="r"when usingsmbclient.shutil.copytree()(but can when usingsmbclient.shutil.copyfile()). It seems this is because the arg is already defined in an internal function (with SMBDirectoryIO(path, share_access="rwd", **kwargs) as fd:). The complete traceback is below.Usage
Error:
I need share access set to read-only or else I get
[NtStatus 0xc0000043] The process cannot access the file because it is being used by another process: .... Why is a basic copy not read-only by default? Also, is there another way of achieving this with the current module version? Thanks!
