Files with attribute temporary invisible in cygwin

Files with attribute temporary invisible in cygwin

[Pavel Kudrna]

There exist files in windows 7 which can't be deleted using cygwin "rm" 
command. Files are visible from windows command line or Windows Explorer 
but are invisible by "ls -lA" command:

$   ls -lA `cygpath 'C:\ProgramData\Microsoft\Diagnosis\DownloadedSettings'`
total 16
-rwxrwx---+ 1 Administrators SYSTEM 1016 Aug 23  2017 
telemetry.ASM-WindowsDefault.json.bk
-rwxrwx---+ 1 Administrators SYSTEM  795 Aug 23  2017 utc.app.json.bk

Dir command from cmd.exe shows that there are 2 more files (with 
extension .json) previously invisible:

c:\>  dir C:\ProgramData\Microsoft\Diagnosis\DownloadedSettings /b
telemetry.ASM-WindowsDefault.json
telemetry.ASM-WindowsDefault.json.bk
utc.app.json
utc.app.json.bk

It seems to be connected with the temporary attribute which both 2 
mentioned files have set:

c:\>  for %i in 
(C:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\*) do @echo %~ai %i
--a----t- 
c:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\telemetry.ASM-WindowsDefault.json
--a------ 
c:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\telemetry.ASM-WindowsDefault.json.bk
--a----t- c:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\utc.app.json
--a------ 
c:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\utc.app.json.bk

Together with above mentioned 2 files

C:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\utc.app.json
C:\ProgramData\Microsoft\Diagnosis\DownloadedSettings\telemetry.ASM-WindowsDefault.json

I have found three more files in Windows 7

C:\ProgramData\Microsoft\Network\Downloader\qmgr0.dat
C:\ProgramData\Microsoft\Network\Downloader\qmgr1.dat
C:\Users\%USERNAME%\AppData\Local\Microsoft\Office\15.0\OfficeFileCache\LocalCacheFileEditManager\FSD-CNRY.FSD

with the same behavior (invisible by ls, undeletable by rm but visible 
from windows) and all have the temporary attribute set.

Files are invisible/undeletable with ls/rm even from WindowsPE which 
does not run from C: disk and can not keep those files open.

Thanks.

With the snapshot 2018-02-14 files with temporary attribute are visible 
and deletable.

But still I have directories undeletable using "rm -R" which contain 
files with both hidden and temporary attributes set.

Duh.  I *knew* I had to remove this "hiding O_TMPFILE files from
readdir" at one point.  No wonder I wrote a matching comment right from
the start.

Of course this can't work with rm -r.  Given rm doesn't see this file it
never unlinks it, so the parent dir can't be removed.

I add this to my List Of Really Bad Ideas.

Still, what files have both attributes set?  What application is
creating these files?  Apart from Cygwin, of course, but Cygwin
O_TMPFILE files are delete-on-close.

Please give it a try.

Files with both hidden and temporary attributes on belong to LabView 
2015. I found 2 in "C:\ProgramData\National Instruments\NI-DAQmx"
{509E1DB5-B477-49b8-AF59-114DC801074C}RrWr.lock
{509E1DB5-B477-49b8-AF59-114DC801074C}Write.lock
and 3 in
"C:\ProgramData\National Instruments\Shared 
Memory\platform\memory\sharedMemoryFiles"
48d09ae7-0894-4c28-ab25-b6f1cdea221f
pimmInternalFloatingSharedHeap
pimmPublicFloatingSharedHeap.

With the snapshot 2018-03-09 all mentioned files are visible by "ls" and 
"rm -r" removes directories with them (I do it offline after reboot to 
Windows PE).

Thank you.
