deleted files with open file handles don't behave correctly in drvfs

[clockfort]

• A brief description
  A deleted file with open file handles on it does not behave correctly on drvfs; it is still semi-visible to some applications when accessed via directory listing. (I have repro'd the issue in ls and git)

• Actual results / repro steps

clockfort@clockfort-sfb:~/desktop/test$ pwd -P      # I'm in a drvfs directory
/mnt/c/Users/clockfort/Desktop/test
clockfort@clockfort-sfb:~/desktop/test$ touch foo.txt
clockfort@clockfort-sfb:~/desktop/test$ lsof | grep foo.txt # I'm keeping less open in another terminal
less    596 clockfort    4r   REG   0,14       0  2533274790569269 /mnt/c/Users/clockfort/Desktop/test/foo.txt
clockfort@clockfort-sfb:~/desktop/test$ rm foo.txt
clockfort@clockfort-sfb:~/desktop/test$ ls
ls: cannot access 'foo.txt': No such file or directory
foo.txt
clockfort@clockfort-sfb:~/desktop/test$ ls foo.txt
ls: cannot access 'foo.txt': No such file or directory
clockfort@clockfort-sfb:~/desktop/test$ rm foo.txt
rm: cannot remove 'foo.txt': No such file or directory
clockfort@clockfort-sfb:~/desktop/test$ lsof | grep foo.txt # I closed the file handle

Hi @clockfort -- thanks for the detailed write-up! I think this is the same underlying issue as #1535 , though a somewhat different scenario. In short, it's a clash between Windows and Linux semantics. Windows doesn't allow you to remove an open file. Linux does. DrvFs must support both simultaneously. Since the two have conflicting requirements, there must necessarily be rough edges; the question is where the WSL team chooses to put them.

Related to that point: Do you have a program or script that depends on the Linux behavior? Or is this just a curiosity that you observed? When trade-offs need to be mande, the WSL team often seems to prefer to make trade-offs in favor of what's most useful to the most people.

[clockfort]

Yeah, I know why there'd be rough edges around this :-)
Sorry I didn't see that other issue because of the misleading overly-specific name; feel free to close this issue as duplicate if that one has the same underlying issue.

My situation specifically was that I had a git directory, and checking out another branch deleted and added files to directory; including a file that a gradle daemon had an open handle on; the checkout threw an error because it couldn't put back a (different version) of the file in the same place.
From there things get really weird, and you can git add the phantom file it thinks is there, but then it simultaneously appears as added as a delete and existing as untracked (??!!), while all the while it's actually deleted and was never there.

@aseering Could #1615 be related as well?

[aseering]

Yeah, certainly possible.

[benhillis]

I believe @JasonLinMS fixed this recently.
