Where does QGIS write its error log messages?
The error I am getting freezes QGIS so I have to ctrl-alt-del. I can see the last message in the panel, but can’t copy it or scroll back to see the earlier messages. When I re-open it, the log message panel has reset to zero (QGIS starting, etc), so all the transform error messages I want are gone.
Why are SVG files not included in QGIS?
If you’re using the QGIS project with styling based on SVG files using relative paths then you should know that the server considers the path relative to its qgis_mapserv.fcgi file (not to the qgs file). So, if you deploy a project on the server and the SVG files are not placed accordingly, the output images may not respect the Desktop styling.
When does QGIS server mark a request as invalid?
When such a request comes, QGIS Server is caching the response and marking the cache valid. At the same time, it watches if the project file changes. If the project is changed then the cache is marked as invalid and QGIS Server waits for a new request in order to recreate the cache.
How is QGIS different from other WMS software?
In contrast to other WMS software, the QGIS Server uses cartographic rules as a configuration language, both for the server configuration and for the user-defined cartographic rules. As QGIS desktop and QGIS Server use the same visualization libraries, the maps that are published on the web look the same as in desktop GIS.
Why are my PostGIS rasters not loading in dB manager?
Sign in to your account PostGIS rasters can be added using DB Manager on a new/clean project (they cannot be loaded from the browser as they do NOT show, I filed a separate ticket for it). If you save a project with PostGIS rasters and then close/reopen it then this rasters are not loaded.
Where do I find the qgsmessagelog output in Python?

Why do I need to open the processing log?
This allows you to know more about what has been done with the processing tools, to solve problems when they happen, and also to re–run previous operations, since the logging system also implements some interactivity. To open the log, select the corresponding entry in the processing menu.
Where to find last algorithm in processing log?
Now go to the log dialog and locate the last algorithm in the list, which corresponds to the algorithm you have just run. Double–click on it an a new result should be produced, just like when you run it using the normal dialog and calling it from the toolbox.
How to disable time based logging in PostgreSQL?
When logging_collector is enabled, this parameter determines the maximum lifetime of an individual log file. After this many minutes have elapsed, a new log file will be created. Set to zero to disable time-based creation of new log files. This parameter can only be set in the postgresql.conf file or on the server command line.
When does PostgreSQL overwrite an existing log file?
When logging_collector is enabled, this parameter will cause PostgreSQL to truncate (overwrite), rather than append to, any existing log file of the same name. However, truncation will occur only when a new file is being opened due to time-based rotation, not during server startup or size-based rotation.
