[QGIS-Developer] Profiler times in Python

[Michel Stuyts]

Until now I always used qgis.utils.plugin_times, but I noticed the different values between this variable and the “Debugging/Development Tools” Panel. That’s the reason I wanted the profiler values.  The qgis.utils.plugin_times variable has 0 loading time as value for some plugins, which is also very unlikely.

Does anyone know the difference these two sources of plugin loading times?

One line I know, maybe this is enough :

>>> from qgis.utils import plugin_times
>>> plugin_times

It's not using the profiler. Values are different from the Profiler, after a quick look...

I want to use the data on plugins from the Profiler.  In the “Debugging/Development Tools” Panel I can see both the total time for all plugins and the individual time per plugin.  With the following Python code, I want to get the same data in Python:

profiler = QgsApplication.profiler()
for child in profiler.childGroups():
    childGroup = profiler.childGroups(child)
    if child == 'Load plugins':
        print(child, profiler.profileTime(child))
        for subGroup in childGroup:
            print(subGroup, profiler.profileTime(subGroup))

It shows the total time for all plugins just fine as “Load plugins” with the same number of seconds as in the Panel, but for the individual plugins I get 0.0 as time for all plugins.  What do I do wrong or is it a bug?
