Hello,

I have found a very specific case where _FileListToArrayRec() hangs.

The setup:

  1. Have a mapped network drive
  2. Put a file in a folder starting with a "-".

For example, map a P drive and then create "P:\-test.txt"

#include <File.au3>
Opt("TrayIconDebug", 1)
$files = _FileListToArrayRec("P:\test\sync", "*", $FLTAR_FILES, $FLTAR_RECUR)
MsgBox(48, "Done", "Done")

Running that code for me never hit's the "Done" message box. If you hover over the tray icon you can see it's stuck in File.au3 indefinitely.

I copied _FileListToArrayRec() into my project and started debugging. It seems as though the files get added to the list, "." and ".." do every time as well which is why the While statement:

While $asFolderSearchList[0] > 0

Never evaluates to false.

If I turn of recursion, then the filter "*||.+" seems to fix this. Experimenting with ways to fix it with recursion enabled. However, this appears to be a bug to me. Note that this doesn't happen on local files.

Seems like if a file with "-" is in the folder, FileFindFirstFile() returns "." and ".." folders which only the DLL call variant of the code handles.

See the following (poorly) instrumented ___FileListToArraRec():
 

Func ___FileListToArrayRec($sFilePath, $sMask = "*", $iReturn = $FLTAR_FILESFOLDERS, $iRecur = $FLTAR_NORECUR, $iSort = $FLTAR_NOSORT, $iReturnPath = $FLTAR_RELPATH)

Here is the output of that logging with "test.txt":

Here is the output with "-test.txt":
 

While no folders

You can see folder . and .. added to the list

Ok, the filter "*||.*" seems to work.

Still think "." and ".." should always be handled by _FileListToArrayRec() let me know what you guys think.

#include <File.au3>
Opt("TrayIconDebug", 1)
$files = _FileListToArrayRec("P:\test\sync", "*||.*", $FLTAR_FILES, $FLTAR_RECUR)
_ArrayDisplay($files)
MsgBox(48, "Done", "Done")

@Melba23 you're on the contributor list for File.au3 wondering your thoughts :)

Note I updated my example with my hacked version of ___FileListToArrayRec()

In this I added 

If $sName = ".." Then
    ContinueLoop
EndIf
If $sName = "." Then
    ContinueLoop
EndIf

To the native code block and the function works.

Also added a simple _Log function so that the code runs.

Complete example:

#include <File.au3>
Opt("TrayIconDebug", 1)
$files = ___FileListToArrayRec("P:\test\sync", "*", $FLTAR_FILES, $FLTAR_RECUR)
_ArrayDisplay($files)
MsgBox(48, "Done", "Done")

Func _Log($message)
    ConsoleWrite($message & @CRLF)

DStark,

We have run into problems with the UDF returning "." and ".." before and we thought we had fixed it - obviously not!

I will take a look at the code (and your suggested fixes) to see if we can put this to bed for once and for all. Thanks for letting us know about the problem.

Hi Melba,

Thanks for the reply!  FYI you may enjoy seeing this - during testing I tried to put "." for the folder exclude filter and it gives me this... Note there is only  P:\test\sync\-test.txt.  This is probably a different issue worth investigating while you're at it 🤣
