Tcl Source Code

tcl 8.6.12, Windows 10, with latest updates applied

Asking for long filename (which does not exist)
    % glob -nocomplain [string repeat x 251]
Ok, empty list.

Adding a "*" makes the path name too long and glob err out
instead of returning an empty list:
    % glob -nocomplain [string repeat x 251]*
    couldn't read directory "C:/Users/ralf/AppData/Local/Temp/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx*": no such file or directory

=> IMHO both commands should return an empty list, even if the second command hits
the MAX_PATH limit in Windows.

As an aside, on Linux I can do

  % glob -nocomplain [string repeat x 1000000]
  % glob -nocomplain [string repeat x 1000000]*

=> empty list each, no error, although trying to create that file also
returns an error since the file name is too long.
