Path to passing Windows Hardware Lab Kit #279

Open lundman opened 1 year ago

lundman commented 1 year ago

Presumably we need to at least pass ifstest.exe cleanly. There are somethings we might never pass, as we do not have the same limitations - if it checks that EAs can only be 64KB etc?

Here is a current run:

ifstest.exe

We should start to chip away at these.

The FileID atrribute is odd

LastGeneralValue :00000080
ExpectedGeneralValue :00000027

So ZFS return FILE_ATTRIBUTE_NORMAL but for some reason it expects 27: FILE_ATTRIBUTE_ARCHIVE|FILE_ATTRIBUTE_READONLY|FILE_ATTRIBUTE_HIDDEN|FILE_ATTRIBUTE_SYSTEM But perhaps it changed Attributes to 27 as a test, and we fail to keep them. This is more likely to be the issue.

The Access/Sharing is known, we need to call those functions in more combinations, and it is fairly low priority to me.

The only real one to look into here is StreamShareTest where we fail creating strmshar:stream2 but should not.

Update: Using FileTest.exe to query attributes and set them to 0x27, will return 0x27 when queried. But if you close the file, and re-open it, it is 0x80. So we need to store attributes to disk.

Update: The new code stores the FileAttributes to disk, using correct xvattr zfs_setattr() calls as well. Takes care of the largest concern in this group. Sharing Violations are as exciting.

We fail a ReadOnly test here, so might be related to OpenCreateGeneral test too.

Plenty AllocationSize issues, mostly ignored that feature, since it is "optionally pre-allocate space". But we should throw that in there.

The lacking STATUS_OBJECT_NAME_COLLISION is probably a real problem to fix.

Turns out it expected to be able to set ValidDataLength to slightly larger than filesize, then when issuing reads beyond filesize, everything should be zeros.
