can't run crossbar under Windows python 3.4.3 (Name Error: twisted\...\lockfile,py)

[Gelonida Gel]

Hi,


The quick version:
=============
- first pip install crossbar  fails ( NameError: name 'file' is not defined )
- second pip install crossbar seems successful
- crossbar init --appdir tst is successful
- crossbar start fails with an error ( NameError: name 'file' is not defined )

slightly longer version:
=================

the exception when running crossbar start is :

(pyxb) d:\tmp\tst>crossbar start
Traceback (most recent call last):
  File "c:\pyxb\Scripts\crossbar-script.py", line 9, in <module>
    load_entry_point('crossbar==0.10.4', 'console_scripts', 'crossbar')()

    options.func(options)

  File "c:\pyxb\lib\site-packages\twisted\python\lockfile.py", line 52, in <module>
    _open = file
NameError: name 'file' is not defined

The long version:
=============
For some local testing I'd like to run crossbar on windows.

I freshly installed python 3.4.3

I freshly installed virtualenv
c:\Python34\Scripts\pip.exe install virtualenv

I create a new virutalenv:
c:\Python34\Scripts\virtualenv.exe c:\pyxb

I activate it:
c:\pyxb\Scripts\activate

I try to install crossbar:
pip install crossbar

the first lines look good, but then things seem to go wrong:

    reading manifest file 'autobahn.egg-info\SOURCES.txt'
    reading manifest template 'MANIFEST.in'
    writing manifest file 'autobahn.egg-info\SOURCES.txt'
    Copying autobahn.egg-info to c:\pyxb\Lib\site-packages\autobahn-0.10.3-py3.4.egg-info

What could be the issue?

Only a few packets were sucessfully installed:

(pyxb) C:\pyxb>pip freeze
autobahn==0.10.3
six==1.9.0
Twisted==15.1.0
txaio==1.0.0
zope.interface==4.1.2

Calling pip install crossbar a second time pretends to be successful

I'm having now:

(pyxb) C:\pyxb>pip freeze
autobahn==0.10.3
cffi==0.9.2
characteristic==14.3.0
crossbar==0.10.4
cryptography==0.8.2
Jinja2==2.7.3
MarkupSafe==0.23
mistune==0.5.1
netaddr==0.7.14
pyasn1==0.1.7
pyasn1-modules==0.0.5
pycparser==2.12
Pygments==2.0.2
pyOpenSSL==0.15.1
PyTrie==0.2
PyYAML==3.11
requests==2.7.0

shutilwhich==1.1.0
six==1.9.0
treq==15.0.0
Twisted==15.1.0
txaio==1.0.0
zope.interface==4.1.2

crossbar init --appdir tst
seems to work

crossbar start
fails with

(pyxb) d:\tmp\tst>crossbar start
Traceback (most recent call last):

Any ideas???

Hi Gel,

Twisted is not yet ready for use with Python3. Use Python 2.7.9 instead.

See

Thanks a lot Roger,

I got confused by the fact, that crossbar clients written in python can be written without twisted (just with asyncio)

So if I understand correctly:
- Crossbar itself depends on twisted, which is still  not ready for python3
- Only the python autobahnclients connecting to crossbar can be written in python3 with asyncio or in python2 with twisteds or trollius (asyncio-port)

Is that right?

[Alexander Gödde]

Hi Gelonida,

that is correct - Crossbar, due to its reliance on Twisted, currently does not run under Python 3.

This is changing though - we're supporting the porting of Twisted to Python 3, and Crossbar.io on Python 3 should be a reality soon.

Regards,

Alex

When running from source, Crossbar now seems to run okay under Python 3.4 on both OSX 10.10.5 and Ubuntu 14.04.

Installing on Windows seems to complete without errors, but running Crossbar there still gives the "name 'file' is not defined" error.

Feels like progress! I'm looking forward to Crossbar/Twisted support for Python 3 on Windows.

Regards,

Harold

[Tobias Oberstein]

Harold,

thanks for reporting back! Yeah, we've made huge progress .. Python 3
credits go mainly to Hawkie for working on CB, and for working on
Twisted (Tavendo/Crossbar.io sponsored this work also).

Rgd the issue: could you please file an issue on Crossbar.io/GitHub
including a complete traceback (log output)?

The 0.11 release is due very soon, and we might have the chance to fix
this before. Probably trivial.

Cheers,
/Tobias

PS: if you have some minutes to spare:

- does the colored logging work on Windows for you?

- does Ctrl-C'ing CB work robustly?

- if you have a CB running with multiple workers, killing any of the
workers (or the controller) should make the whole node shutdown, and
shutdown all the (other) workers along

Hey Tobias,

since I ran into the same problem few minutes ago and didn't find the issue on CB,

There is a ticket on twisted for this: 

https://twistedmatrix.com/trac/ticket/7626

C:\Anaconda3\Scripts>crossbar version

Traceback (most recent call last):

  File "c:\anaconda3\lib\runpy.py", line 170, in _run_module_as_main

  File "c:\anaconda3\lib\site-packages\twisted\python\lockfile.py", line 52, in <module>

    _open = file

NameError: name 'file' is not defined.

To answer your question, there isn't any color on the windows prompt.

Cannot verify the CTRL+C since CB ist not running yet ;-)

Tobias

Hi tobias!

I've added this as an issue in the Crossbar repo (https://github.com/crossbario/crossbar/issues/462), with links to both this conversation and the twisted issue. Thanks for reporting this!

Regards,

Alex

[tobias...@t-online.de]

Thanks alex.
I'm really looking forward to install this technology in our labroratories.

Tobias
