googleappengine install pudb

Question

I'm want to debug my python application on google app engine with pudb. I've installed buildout without of using virtualenv and created config file for it buildout.cfg:

[buildout]
develop = .
parts =
    python
    app
    pudb
    nosetests
    zipsymlink

eggs =
    gaeapp

unzip = true

[python]
recipe = zc.recipe.egg
interpreter = python
eggs = ${buildout:eggs}

[app]
recipe = rod.recipe.appengine
url = https://storage.googleapis.com/appengine-sdks/featured/google_appengine_1.9.11.zip
server-script = dev_appserver
src = ${buildout:directory}/src/gaeapp
exclude = tests
zip-packages = True

[pudb]
recipe = zc.recipe.egg
eggs =
    gaeapp
    pudb

[nosetests]
recipe = zc.recipe.egg
eggs =
    NoseGAE
    WebTest
    gaeapp
    nose

extra-paths =
    ${buildout:directory}/etc
    ${buildout:directory}/parts/google_appengine
    ${buildout:directory}/parts/google_appengine/lib/antlr3
    ${buildout:directory}/parts/google_appengine/lib/fancy_urllib
    ${buildout:directory}/parts/google_appengine/lib/ipaddr
    ${buildout:directory}/parts/google_appengine/lib/webob_1_1_1
    ${buildout:directory}/parts/google_appengine/lib/webapp2/
    ${buildout:directory}/parts/google_appengine/lib/yaml/lib

interpreter = python

[zipsymlink]
recipe = svetlyak40wt.recipe.symlinks
path = ${app:src}
files = ${app:app-directory}/packages.zip

# Tools and dependencies
svetlyak40wt.recipe.symlinks = 0.2.1

My app.yaml:

application: gaeapp
runtime: python27
threadsafe: true
api_version: 1

handlers:
- url: /_ah/spi/.*
  script: gae_api.APPLICATION

libraries:
- name: pycrypto
  version: latest

- name: endpoints
  version: 1.0

- name: setuptools
  version: latest

- name: webob
  version: latest

- name: webapp2
  version: latest

builtins:
- deferred: on

My setup.py:

from setuptools import setup, find_packages

setup(
    name = "gaeapp",
    version = "1.0",
    url = 'http://github.com/blabla/gaeapp',
    license = 'BSD',
    description = "Just a test GAE app.",
    author = 'WOW',
    packages = find_packages('src'),
    package_dir = {'': 'src'},
    install_requires = ['setuptools', 'pudb']
)

Everything installed fine, nosetests and devappserver are works. Run server:

bin/devappserver parts/app

I'm trying to use pudb in code:

import pudb; pudb.set_trace();

And just see such error:

ImportError: No module named pudb

Are there any ways to use pudb with GAE apps?

You need to tell rod.recipe.appengine what eggs to copy:

packages =
    pudb
    urwid

I just tried, after I runned `bin/buildout` and It's didn't help, have the same error. – Igor Komar Sep 22 '14 at 23:38
what is in the `parts/app` directory? Can you also look into the zip file produced for the libraries? – Martijn Pieters Sep 23 '14 at 06:44
yes, of course. If I write in `app` part just this code as you said `eggs = gaeapp`, the `parts/app` structure is: `gaeapp` - copy of my project. Else if I write in `app` part this `eggs = gaeapp, pudb` the `parts/app` will be: `gaeapp` - copy of my project, `EGGS-INFO` , `packages.zip` - there are a file `pkg_resources.py` in which: `def _dummy_func(*args): pass declare_namespace = _dummy_func resource_filename = _dummy_func` – Igor Komar Sep 23 '14 at 08:37
@kazantip: and that's the full contents of `packages.zip`? Then the dependency wasn't copied in. Try adding `pudb` to the eggs list explicitly. – Martijn Pieters Sep 23 '14 at 09:08
ok, I've added `pudb` in `app -> eggs` list, the `packages.zip` hasn't changed. – Igor Komar Sep 23 '14 at 09:20
@kazantip: next option: `packages = pudb`. – Martijn Pieters Sep 23 '14 at 09:23
Added `packages = pudb` and in packages.zip appeared folder packages, which contains pudb. Now `import pudb` is - ok, but when I write `pudb.set_trace()` => I have the next error `File "packages.zip/pudb/debugger.py", line 5, in ImportError: No module named urwid` – Igor Komar Sep 23 '14 at 10:11
@kazantip: so `urwid` is another dependency you need to add. – Martijn Pieters Sep 23 '14 at 10:26
@kazantip: Personally, I use [`appfy.recipe.gae`](https://pypi.python.org/pypi/appfy.recipe.gae/0.9.7) instead; gives me more control over what is included, as I can then specify in app.yaml what not to upload (e.g. exclude debugging tools and local libraries GAE has local copies of for me). – Martijn Pieters Sep 23 '14 at 10:28
I'm sorry, but I really doesn't know why google app engine gives such error now: `google_appengine/google/appengine/tools/devappserver2/python/sandbox.py", line 886, in load_module` `ImportError: No module named termios`. Think it's strange – Igor Komar Sep 23 '14 at 13:23
You are deploying a debugger library that relies on access to the terminal. There is no terminal on GAE, and that means there are no terminal-specific libraries like `termios` either. – Martijn Pieters Sep 23 '14 at 13:26
yes, but this error shows locally in dev server, I didn't deployed it in cloud. – Igor Komar Sep 23 '14 at 13:33
But the dev server tries to faithfully reproduce the server environment for you. That includes hiding stdlib libraries not available on GAE. – Martijn Pieters Sep 23 '14 at 13:42
so, thanks a lot, now I will be know, that it impossible to use comfortable debugger while developing GAE apps. – Igor Komar Sep 23 '14 at 13:46
