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

[Philip Nienhuis]

Follow-up Comment #3, bug #31080 (project octave):

Octave 3.7.7+ MXE GUI built for MinGW, installed on drive X, and Octave-3.6.7+
MXE CLI (ditto):

With either script or function files, it doesn't even work in a subdir of
root:

octave-cli.exe:1> pwd
ans = X:\Octave\octave-3.7.6+_MXE
octave-cli.exe:2> cd f:/tmp
octave-cli.exe:3> edit script.m
octave-cli.exe:5> dir script.m
script.m
octave-cli.exe:6> script
error: 'script' undefined near line 1 column 1
octave-cli.exe:6> rehash
octave-cli.exe:7> script
error: 'script' undefined near line 1 column 1
octave-cli.exe:7> clear -f
octave-cli.exe:8> script
error: 'script' undefined near line 1 column 1
octave-cli.exe:8>
:
:
octave-cli.exe:8> cd /
octave-cli.exe:9> pwd
ans = f:\
octave-cli.exe:10> edit script2.m
octave-cli.exe:11> dir *.m
script2.m
octave-cli.exe:12> script2
error: 'script2' undefined near line 1 column 1
octave-cli.exe:12>


After restarting, Octave behaves even stranger:


octave-cli.exe:1> cd f:\tmp
octave-cli.exe:2> dir *.m
funcfil.m                  strread_bitw_regexp.m      textread.m
script.m                   strread_bitwidth.m         textscan.m
strread.m                  strread_bitwidth_regexp.m
octave-cli.exe:3> funcfil    ## Works OK
Hello world!

octave-cli.exe:4> script     ## does nothing
octave-cli.exe:5> type script.m
script.m is the user-defined function defined from: .\script.m

disp ("Hello World!\n")';

octave-cli.exe:6>
octave-cli.exe:7> cd /
octave-cli.exe:8> dir *.m
funcfil2.m  script2.m
octave-cli.exe:9> script2    ## Works OK;
Script 2

octave-cli.exe:10> funcfil2
octave-cli.exe:11> funcfil2
octave-cli.exe:12> type funcfil2
funcfil2 is the user-defined function defined from: f:\funcfil2.m

function [retval] = funcfil2 ()

        disp ("Funcfil2\n")';

endfunction

octave-cli.exe:13> type script2
script2 is the user-defined function defined from: f:\script2.m

disp ("Script 2\n");

octave-cli.exe:15>which funcfil2
'funcfil2' is a function from the file f:\funcfil2.m


Striking is that it works upon restart for functions but not for scripts in a
subdir, and the other way round in the root dir.

Could these be MinGW bugs (in the gcc runtime libraries)?
