[Octave-bug-tracker] [bug #31080] User scripts or functions created during a session on Windows are not found

[Dennis Cote]

Follow-up Comment #78, bug #31080 (group octave):

Rereading these bug reports start from the beginning I see there is another
issue with directory timestamp on Windows directories. I decided to retest
using my current directory. I still see this issue. A slightly edited command
history (some file names redacted) is shown below. I'm using Octave 9.3.0 on
Windows 11.

>> dir

...
I redacted many file names.
File bug.m does exist in current directory
which is on the load path.

>> dir bug.m
bug.m
>> bug
error: 'bug' undefined near line 1, column 1
>> path(path());
>> bug
bug testing
ans = 0
>> 


The content of bug.m is a large comment header inserted by the edit command
followed by:


function retval = bug (input1, input2)
  display("bug testing");
  retval = 0;
endfunction


The first thing I noticed is that the format of the timestamps returned by the
stat command have changed from integers to exponential floating point with
only 5 digits of precision.

My C: drive is an NTFS drive. This is happening in a sub-directory rather than
at the root of a drive.

The path(path()) workaround does cause Octave to find and execute the bug.m
file.
