[Octave-bug-tracker] [bug #53006] GUI Documentation Browser displays Index chapters of manual poorly

[Dan Sebald]

Follow-up Comment #74, bug #53006 (project octave):

OK, I've found the issue.  The QHelpEngine or one of its associated components
is generating a hidden temporary directory.  With the hard-coded address and
copies in the launch directory, after launching Octave GUI there appears


address@hidden ~/octave/bug/53006 $ ls -la
[snip]
drwxrwxr-x  2 sebald sebald    4096 .octave_interpreter



address@hidden ~/octave/bug/53006 $ ls -la .octave_interpreter/
total 1808
drwxrwxr-x 2 sebald sebald    4096 .
drwxrwxr-x 3 sebald sebald    4096 ..
-rw-rw-r-- 1 sebald sebald 1833841 _218.cfs
-rw-rw-r-- 1 sebald sebald       4 deletable
-rw-rw-r-- 1 sebald sebald      29 segments


After exiting the program and taking out the hard-coded path and recompiling,
I removed the above hidden directory and re-ran Octave GUI.  No new hidden
directory appeared.

So, my guess is that the hidden directory is being attempted in the
non-permission build directory.  Whether this is a consequence of attempting
to use the [build-dir]/run-octave environment setup or something more general,
it can't be that an installed Octave attempts to create a hidden directory in
the location of the QHC file.  To investigate, I've installed Octave, run the
GUI and get a model error dialog:

"Could not setup the data required for the documentation viewer. Only help
texts in the Console Widget will be available."

and after clicking "OK" Octave crashes.  Launch again, "OK", crash.

The usual issues.  I realize this is in the nascent stage, but it takes time
to make new features work robustly.
