Error while packing keyring module with PY2APP on MAC OSX

Question

I am making an app in python which needs to store keys. I used keyring module to store keys. I am using python-2.7 and osx 10.8.5 with keyring 3.2( easy_install keyring). Code is running fine on eclipse, but when I converted code into app using py2app, it shows error of MYAPP Error open console Terminate

import keyring
keyring.set_password("title","section","keys")
res= keyring.get_password("title","section")

I included terminal response scrap when typed "python setup.py py2app" while making dist through py2app

Answer 1

Not sure if you ever solved this, but I had a similar issue on my Mac (with python v2.7.6 and py2app v0.9): the script ran fine from the command line (ie, python scriptname.py ), but when I used py2app to convert it to a .app , it failed.

The Console messages led me to conclude that py2app wasn't smart enough to include the submodules from the keyring.backends module. So I explicitly imported everything there and it finally worked:

import keyring.backends.file
import keyring.backends.Gnome
import keyring.backends.Google
import keyring.backends.kwallet
import keyring.backends.multi
import keyring.backends.OS_X
import keyring.backends.pyfs
import keyring.backends.SecretService
import keyring.backends.Windows
import keyring

I hope this helps you!

I don't have the possibility to try this out locally, here's my best guess:

Try importing all the bits you'll actually need in the app, including exceptions that don't occur during "normal" execution

import keyring
import keyring.set_password as _unused_1
import keyring.backend
import keyring.backend.PasswordSetError as _unused_2

You may also require some other package at runtime, to check that, do the following:

$ python2.7
Python 2.7.5 (default, Sep  6 2013, 09:55:21) 
[GCC 4.8.1 20130725 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> before = sys.modules.keys()
>>> import keyring
>>> middle = sys.modules.keys()
>>> keyring.set_password("a", "b", "c")
Please set a password for your new keyring
Password: 
Password (again): 
Please input your password for the keyring
Password: 
>>> after = sys.modules.keys()
#
# now the interesting bits
#
>>> set(after).difference(set(middle))
set(['struct', 'crypt', 'base64', 'binascii', 'keyring.crypt', 'encodings.base64', 'encodings.base64_codec', '_struct'])
#
# and this
#
>>> set(middle).difference(set(before))
set(['cStringIO', 'heapq', 'logging.threading', 'sre_compile', '_collections', 'logging.cStringIO', '_sre', 'getpass', 'atexit', 'keyring.backend', 'logging.os', 'operator', 'Crypto.Cipher.AES', 'logging.traceback', 'keyring.os', '_heapq', 'logging.time', 'keyring.ConfigParser', 'logging.weakref', 're', 'keyring.getpass', 'sre_constants', 'imp', 'logging.codecs', 'collections', 'logging.thread', 'keyring.imp', 'keyring.logging', 'keyring.keyring', 'string', 'keyring.util.re', 'time', 'Crypto', 'termios', 'keyring.util.escape', 'logging', 'logging.atexit', 'keyring.util', 'logging.sys', 'keyring.abc', 'Crypto.Cipher', 'ConfigParser', 'keyring.util.string', 'keyring.getpassbackend', 'keyword', 'thread', 'strop', 'traceback', 'keyring', 'weakref', 'threading', 'itertools', 'keyring.Crypto', 'keyring.sys', 'sre_parse', 'logging.warnings', 'keyring.core'])

You see how many modules were brought in as a result of import keyring , but also some more modules got brought in as a result of keyring.set_password(...) .

Now, most of this should be automatic with py2app , but some runtime dependencies can be missed.

The reason behind this is that py2app does something tricky when it decides which modules to include. Pretend that keyring.set_password() doesn't actually run at this phase. In fact if it did and set_password must have side effects, would you expect py2app to package a plain or modified module?

在setup.py中包含packages ='keyring.backends'以包含密钥环的所有包。
