[Octave-bug-tracker] [bug #58127] -append does not automatically detect/check file type for save

[Rik]

Update of bug #58127 (project octave):

                  Status:               Need Info => Confirmed              
                 Release:                   5.1.0 => dev                    
        Operating System:       Microsoft Windows => Any                    
                 Summary: save -V7 and -append error  => -append does not
automatically detect/check file type for save

Follow-up Comment #7:

Marking as confirmed, but changing the Summary to reflect the specific issue.

When the file type for the original save and the file type of the '-append'
save match, then the operation completes succesfully.  However, if they do not
match then strange errors are thrown that don't immediately point back to this
root cause.

Sample code


a=1;b=2;
unlink ('ab.mat');
save -v7 ab.mat a
save -text -append ab.mat b
clear a b
load ab.mat
a
b


This code fails with


error: load: invalid element type = 8227


However, if you specify matching formats then it works correctly


a=1;b=2;
unlink ('ab.mat');
save -v7 ab.mat a
save -v7 -append ab.mat b
clear a b
load ab.mat
a
b
