[Qgis-psc] 2025 Grant: Coverity Scan cleanup progress report

[Nyall Dawson]

Hi PSC,

In regards to the 2025 funding grant for QEP 337: Coverity Scan
cleanup -- the short story is that this is still an ongoing work in
progress.

While the work started quickly, unfortunately it was delayed for a
significant portion of the year after the Coverity scan compilation
tool broke on newer development environments. It's only recently that
I've been able to resume work on this project, and have been pushing
hard over the last fortnight to get it wrapped up quickly (see links
below). I estimate that there's another 2 weeks remaining here before
I can complete the project.

While the tool was broken on desktop environments, I attempted the
second part of the project (investigating whether it is possible to
automatically run the Coverity Scan tool on a weekly basis as a GitHub
action). (see https://github.com/nyalldawson/QGIS/tree/coverity_workflow).
My finding was that this is NOT possible to achieve via GitHub
actions, as the compilation using the coverity cov-build tool ends up
exceeding the maximum available space on the workflow runners.

I will report back with an updated status regarding completion of this
work mid-November.

Kind regards,
Nyall
