[gdal-dev] [gdal Python] Exceptions not reset correctly if gdal.UseExceptions() is used

[Luca Fasano]

Hi all,
I suspect there is a bug in gdal.UseExceptions() in python binding. 
I noticed that if a RuntimeError has been generated, following gdal
instructions *raise the same exception*.
It seems that a gdal.ErrorReset() is necessary to reset it.
An example with ipython:

In [2]: from osgeo import gdal

In [3]: gdal.UseExceptions()

In [4]: dataset = gdal.Open('./filename.wrongformat')
---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call
last)

/home/fasano/Desktop/test/<ipython console> in <module>()

RuntimeError: `./filename.wrongformat' not recognised as a supported
file format.


In [5]: gdal.GetCacheMax()
---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call
last)

/home/fasano/Desktop/test/<ipython console> in <module>()

RuntimeError: `./filename.wrongformat' not recognised as a supported
file format.


In [6]: gdal.ErrorReset()

In [7]: gdal.GetCacheMax()
Out[7]: 41943040
 

(My gdal version is 1.5.4)
