NOTE could simple use a dict and populate it, NOTE not sure if this changes things though if monkey patching import.....

local_import_aux(name, reload_force=True, app='welcome')
In apps, instead of importing a local module (in applications/app/modules) with:: import a.b.c as d you should do:: d = local_import('a.b.c') or (to force a reload): d = local_import('a.b.c', reload=True) This prevents conflict between applications and un-necessary execs. source code

build_environment(request, response, session, store_current=True)
Build the environment dictionary into which web2py files are executed.

source code

save_pyc(filename)
Bytecode compiles the file `filename`

source code

read_pyc(filename)
Read the code inside a bytecode compiled file if the MAGIC number is compatible

source code

compile_views(folder)
Compiles all the views in the application specified by `folder`

source code

compile_models(folder)
Compiles all the models in the application specified by `folder`

source code

compile_controllers(folder)
Compiles all the controllers in the application specified by `folder`

source code

run_models_in(environment)
Runs all models (in the app specified by the current folder) It tries pre-compiled models first before compiling them.

source code

run_controller_in(controller, function, environment)
Runs the controller.function() (for the app specified by the current folder).

source code

run_view_in(environment)
Executes the view for the requested action.

source code

remove_compiled_application(folder)
Deletes the folder `compiled` containing the compiled application.

source code

compile_application(folder)
Compiles all models, views, controller for the application in `folder`.

local_import_aux(name, reload_force=True, app=`'welcome'`)

source code


In apps, instead of importing a local module
(in applications/app/modules) with::

   import a.b.c as d

you should do::

   d = local_import('a.b.c')

or (to force a reload):

   d = local_import('a.b.c', reload=True)

This prevents conflict between applications and un-necessary execs.
It can be used to import any module, including regular Python modules.

read_pyc(filename)

source code

Read the code inside a bytecode compiled file if the MAGIC number is compatible

:returns: a code object

run_controller_in(controller, function, environment)

source code

Runs the controller.function() (for the app specified by the current folder). It tries pre-compiled controller_function.pyc first before compiling it.

run_view_in(environment)

source code

Executes the view for the requested action. The view is the one specified in `response.view` or determined by the url or `view/generic.extension` It tries the pre-compiled views_controller_function.pyc before compiling it.

test()

source code

Example:

   >>> import traceback, types
   >>> environment={'x':1}
   >>> open('a.py', 'w').write('print 1/x')
   >>> save_pyc('a.py')
   >>> os.unlink('a.py')
   >>> if type(read_pyc('a.pyc'))==types.CodeType: print 'code'
   code
   >>> exec read_pyc('a.pyc') in environment
   1
