#392: sys.exec_prefix does not point to folder with pythonw.exe thus introducing
inconsistency,e.g. with multiprocessing in QGIS plugins
-------------------+--------------------------------------------------------
Reporter: mlt | Owner: osgeo4w-dev@…
Type: defect | Status: new
Priority: major | Component: Installer
Version: | Keywords: python
-------------------+--------------------------------------------------------
Multiprocessing python module on Windows platform relies on starting a new
process as that platform lacks fork(). Head-on attempt to use that module
from, e.g, QGIS plugin results in a launch of another QGIS instance. To
circumvent this,
[http://docs.python.org/2/library/multiprocessing.html#multiprocessing.set_executable
multiprocessing documentation suggest] to use
{{{
set_executable(os.path.join(sys.exec_prefix, 'pythonw.exe'))
}}}
however pythonw.exe is shipped in bin/ and not in apps/Python27/ where
exec_prefix points to.
