[Octave-bug-tracker] [bug #46849] Shadowing warning on every command for function in +package directory

[Rik]

Follow-up Comment #8, bug #46849 (project octave):

Octave is expected, and thus designed, to pick up changes in scripts and the
addition of new functions automatically.  Reversing that assumption would be a
major design choice that would need to be discussed among the maintainers over
on Discourse.

I also agree though that I've never been particularly happy with the
performance consequences of this choice.  Some of it is ameliorated in that
the load_path system caches the modification times on the directories and
doesn't actually read each directory every time.  Instead, it just does a
check of the modification time and compares it to the last time Octave parsed
the directory.  Most (>99%) of the time nothing has changed and so the test is
quick.  On most UNIX-based operating systems inodes are cached if there is
sufficient memory so checking the timestamp doesn't even mean a read of a slow
device like a disk drive.  Instead, it is just a memory read.
