[issue11676] imp.load_module and submodules - doc issue, or bug?

[Dave Peck]

Dave Peck davep...@gmail.com added the comment:

Definitely could agree with this assessment, but it is surprising given the 
lack of parallel behavior between 'import' and 'imp'.

Note that imp.load_module(subpackage) _does_ modify the parent module's 
attributes -- but it will never put the subpackage attribute itself on parent. 
That's the part that made me think it shouldn't work this way and that its more 
bug than documentation. (That, and the specific use of the imp module in 
Google's dev_appserver.py which indicates that others have the same expectation 
of load_module() that I did.)

[issue11676] imp.load_module and submodules - doc issue, or bug?

[Dave Peck]

New submission from Dave Peck davep...@gmail.com:

If you use `import` to load a package and subpackage:

import package
import package.subpackage
  
Then the `package` module instance will contain a `subpackage` attribute:

assert subpackage in dir(sys.modules['package']), This works.
  
But if you use Python's `imp` module to import these packages instead, the same 
assertion will fail.

Is this a python documentation oversight, or a bug with the `imp` module? 

To reproduce, clone the associated hg repro and follow the instructions in the 
README file. Thanks!
