I have discovered that one of my plugins is associated with an old work
address that no longer exists, how do I go about changing it?

It's https://plugins.qgis.org/plugins/osgb-plugin/#plugin-details if that
helps

Cheers

Subject: [QGIS-Developer] Line feature callout labels not rendering in
 headless/server QGIS 3.22, but work fine in Desktop 3.28
Message-ID: <OSZP286MB14196731EE708EAF12BFC963BDD42@OSZP286MB1419.JPNP286.PROD.OUTLOOK.COM>

Hi all,
My name is Yoshimi, a company employee based in Nagoya, Japan. I'm not a core GIS developer, but I've run into an issue during a project and would appreciate any pointers from this community.
I'm running into an issue where simple callout labels on LineString features fail to render at all when generated via a headless QGIS batch process (PyQGIS, Linux container), while the exact same .qml style and the exact same data render the callouts correctly when loaded manually in QGIS Desktop.
Environment:

  *   QGIS Desktop version (works correctly): 3.28.0, Windows
  *   QGIS server/headless version (fails): 3.22 (Ubuntu 22.04 apt package, qgis + python3-qgis), running in a Docker container, driven via PyQGIS (QgsApplication headless, no GUI event loop)
  *   Data source: PostGIS, LineString geometry, EPSG:6677
  *   Output: PDF via QgsLayoutExporter (print layout export)

Label/callout configuration (rule-based labeling):

<placement priority="5" placementFlags="10" placement="6" dist="30"
           overlapHandling="AllowOverlapIfRequired" .../>
<rendering unplacedVisibility="1" obstacle="0" .../>
<callout type="simple">
  ... anchorPoint="point_on_exterior" labelAnchorPoint="point_on_exterior"
      minLength="0" offsetFromAnchor="0" offsetFromLabel="0" ...
</callout>


Symptom:

  *   The line geometry itself renders correctly in the output PDF.
  *   The callout (leader line + label box) is completely absent in the batch/server output ? not partially clipped, not overlapping with anything, just not drawn at all.
  *   No errors or warnings appear in the QGIS process log during style loading (layer.loadNamedStyle() returns success) or during layout export.
  *   Forcing unplacedVisibility="1" (always show, even if placement fails) made no difference.
  *   Changing anchorPoint from pole_of_inaccessibility to point_on_exterior made no difference.
  *   Ruled out: NULL/empty label field values (confirmed via logs), layer density/overlap competition (confirmed via an isolated manual test loading only the affected features), clipping at the map item's boundary edge.
  *   The same .qml, loaded onto the same features in QGIS Desktop 3.28.0, renders the callouts perfectly.

Question: Is there a known behavioral difference between QGIS 3.22 and 3.28 (or between interactive Desktop rendering and headless/server rendering via QgsLayoutExporter) regarding callout placement for line geometries? Or any known issue/limitation with calloutType="simple" specifically in non-interactive/headless rendering contexts?
Any pointers on where to look (label engine internals, GEOS version dependency, changelog entries between 3.22 and 3.28 related to labeling/callouts, missing processEvents() calls, etc.) would be greatly appreciated.
Thanks, Yoshimi

You are asking a question about ancient history.  3.22 was released in
2021-10 and 3.28 in 2022-10.  The current LTR is 3.44 and the current
release is 4.2.  It would not be surprising if there were bugs in 3.22,
but I doubt anyone is paying attention or has any interest in thinking
about them.

My advice is don't look into that, and update both your headless
rendering and desktop to 3.44.  If you aren't willing to upgrade, it
seems like the obvious experiments are to try 3.28.0 on Ubuntu both
headless and desktop.

Hi Ian,

You can update the email address associated with your plugin directly in
the plugin's Edit form on the QGIS Plugins website (
https://plugins.qgis.org/plugins/osgb-plugin/update/). It's also advised to
update the email address in the metadata.txt if you ever upload a new
version in the future.
I hope this helps,

Best regards,
Lova Andriarimalala
