Description

New description:

the tools returns a python error

Traceback (most recent call last):
File "/usr/share/qgis/python/plugins/GdalTools/tools/doExtractProj.py", line 111, in accept
self.extractor.fileProcessed.connect(self.updateProgress)
AttributeError: 'ExtractThread' object has no attribute 'fileProcessed'

tested on 2.16 on both Win and Lin

The same tools in the Processing toolbox runs with no issues.

Old description:

If you run:

Menu Raster => Projections => Extract projection

on a Geotiff (no matter of compression type or colour depth) the program gets stuck, needing a process kill.

I attach a test raster of mine: thx in advance, gentlemen.

History

#1 Updated by Johannes Kroeger almost 8 years ago

On Linux I got the following Python error dialog:

An error has occurred while executing Python code: 

AttributeError: 'ExtractThread' object has no attribute 'fileProcessed' 
Traceback (most recent call last):
  File "/usr/share/qgis/python/plugins/GdalTools/tools/doExtractProj.py", line 111, in accept
    self.extractor.fileProcessed.connect(self.updateProgress)
AttributeError: 'ExtractThread' object has no attribute 'fileProcessed'

Python version: 2.7.12 (default, Jun 28 2016, 08:31:05) [GCC 6.1.1 20160602] 
QGIS version: 2.99.0-Master Master, c9d6269

Afterwards I could simply close the dialogs. The mouse pointer stayed "in progress" but the program worked fine for me. Does it really complete freeze for you? Do you get no error message?

Yes Sir, completely frozen, without any warning nor mercy :(
Are you sure your 2.16 under Linux creates a working .WLD file..?

#3 Updated by Giovanni Manghi almost 8 years ago

  • Operating System deleted (Windows)
  • Priority changed from Normal to Severe/Regression
  • Subject changed from Freezing upon worldfile's extraction to "extract projection" broken in GDAL tools
  • File alpha.wld added
  • Category set to GDAL Tools
  • Crashes QGIS or corrupts data changed from Yes to No

I have tested the tool in the raster menu on both Windows and Linux and on both platforms the result is the same

Traceback (most recent call last):
File "/usr/share/qgis/python/plugins/GdalTools/tools/doExtractProj.py", line 111, in accept
self.extractor.fileProcessed.connect(self.updateProgress)
AttributeError: 'ExtractThread' object has no attribute 'fileProcessed'

that is of course a regression, but is not the issue you are seeing.

On the other hand the very same tool in the Processing toolbox works fine also with your sample data.

Please try again: make a backup of your .qgis2 folder, then delete it and restart QGIS. After that report if something changed.

Well done, Alex: your patch works like a charm :)
