[Octave-bug-tracker] [bug #58547] gzip() does not handle relative paths in first argument correctly

[Kai Torben Ohlhus]

Update of bug #58547 (project octave):

                  Status:                    None => Patch Submitted        
                 Release:                   5.2.0 => 6.0.90

Follow-up Comment #1:

Confirmed.  Octave 5 is no longer under development => change release to
Octave 6 (bug also present in Octave 7).

All tests performed on openSUSE 15.1 manually compiled Octave versions.


% Setup
mkdir ('foo/bar');
A = rand (4);
save foo/A.mat     A
save foo/bar/B.mat A



% Matlab R2019a
gzip ('foo')      % [1] creates foo/A.mat.gz
                  %         and foo/bar/B.mat.gz
gzip ('foo/bar')  % [2] creates foo/bar/B.mat.gz

gzip ('foo',     'outdir') % [3] creates outdir/A.mat.gz
                           %         and outdir/B.mat.gz
gzip ('foo/bar', 'outdir') % [4] creates outdir/B.mat.gz


In Octave 5.2.0, 6, and 7 (compiled today):

- calls [1] and [2] work
- calls [3] and [4] not (an empty directory "outdir" is created for each
call)

Had no time to try your patch yet.
