Update of bug #31080 (project octave):

                  Status:               Need Info => Confirmed              
                 Release:                   3.6.0 => 3.8.0

Follow-up Comment #7:

Very definitely confirmed.  Octave seems to be caching the contents of a
directory on start-up and then never updating the cache.  This could be down
to differences in how the operating system updates the inode timestamp for the
directory.

On Linux, creating a new file in a directory updates the timestamp.  I think
Octave is comparing the current directory timestamp against the cached
timestamp to figure out if it needs to go and re-read the directory.

On Windows, creating a new file in a directory does not change the
timestamp--I know because I tried.  However, I have the UNIX tool touch.exe
installed and when I touch the directory to bring the timestamp up to the
current time then Octave correctly finds the new m-files.

This sequence worked:


cd e:\
mkdir tmptst
cd tmptst
edit junk.m
## Add some code to junk.m in the editor and then quit
which junk.m
## Returns nothing
## Now, in another shell window execute touch e:\tmptst
which junk.m
'junk.m' is the file e:\tmptst\junk.m


Seems like it might require a lot of O/S specific code to solve this one.
