#41: EnsureDispatch and EnsureModule not working on win32
--------------------------+-------------------------------------------------
Id: 41 | Status: new
Component: PyInstaller | Modified: Mon Feb 20 18:19:12 2006
Severity: major | Milestone:
Priority: normal | Version: PyInstaller 1.0

--------------------------+-------------------------------------------------
!EnsureDispatch and !EnsureModule call the makepy code in gencache at
runtime to greate the early binding support files in the gen_py folder.
This fails under pyinstaller runtime with an !ImportFailure in
win32com.client.gencache._GetModule() from the __import__ function due to
confusion over the various gen_py folders.
The solution is to change the __path__ of the genpy module to be the
support\gen_py folder only. Currently this is set by win32com\__init__.py
to be win32com\gen_py or %temp%\gen_py.
patch:

}}}
However this is only a partial fix as in order for the files to be
correctly created at run time the win32com\gen_py or %temp%\gen_py must
not contain files when the pyinstaller analysis runs. Presumably a issue
with the package paths and importhook in iu.py, may just need __init__.py
to fail.
The current situation also means files may found in a place on a developer
machine that does not exist on the user's target machine (win32com\genpy)
causing user errors not seen by developer.
Out of interest when this works correctly and pyinstaller runtime only
ever uses it's support\gen_py it will be possible to copy makepy created
files from win32com\gen_py into the support\gen_py and they will work
WITHOUT the need to import them.
