Hi Martin,
as already mentioned by Marco, there seems to be a problem with the latest
fix. I have multiple postgres layers and after every redraw only one layer
(random) is drawn (sometimes not even one layer).
When I quit QGIS I get a segmentation fault in the postgres provider
(QgsPostgresConn, member methods called on a NULL pointer), backtrace
attached.
Matthias,
the latest fix should solve both problems. In the previous commit I
have removed automatic closing of postgres cursor when iterating over
features finishes and this caused that a new cursor (with the same
name) was being opened while the old one still existed.
Martin
Layers are rendered correctly again.
However, dataProvider.getFeatures() doesn't return any features in my
plugin ( the same instructions used to work before your last two commits ).
The postgres provider logs the following:
-------------
2 cursor states lost.
SQL: DECLARE qgisf6 BINARY CURSOR FOR SELECT
asbinary(force_2d("situation_geometry"),'NDR'),"gid","obj_id"::text,"type"::text,"node_type"::text,"level"::text,"usage_current"::text,"cover_level"::text,"description"::text,asewkt("detail_geometry")
FROM "qgep"."vw_network_node"
Result: 7 (ERROR: cursor "qgisf6" already exists
)
-------------
Query: move absolute 0 in qgisf6 returned 7 [ERROR: cursor "qgisf6"
does not exist
]
-------------
Regards,
Matthias
