IPyShell import error on binary editra 0.3 #46

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. install editra binary for windows
2. install IPyshell plugin
3. restart editra editra, enable log, open plugin manager

What is the expected output? What do you see instead?

no error in log, ipyshell showup else we've got this error:
[21:29:09][pluginmgr][err] Couldn't Load IPyShell: cannot import name Release

standard install from source works.

Ok I've replaced plugin.pyo by plugin.py in library.zip.
And disbaled exception handling as you suggered...

The strange thing is that it can't find commands that is a standard plugin...
Arff..

I think that the py2exed editra doesn't include all the standard modules...

Is this a good diag?
If yes, then there is something wrong with editra py2exe package.

Yes, py2exe will only include the modules that it finds Editra using. If you 
need
some modules from the standard lib that are not included I can add them to the 
build
script.

Please test by adding the commands module to the INCLUDES list in setup.py then 
run 

python setup.py py2exe

This will build a binary version of Editra in the dist folder you can then run
Editra.exe in that folder to test if that is the only other module needed.

Report back here with what modules are needed and I will add them for the next 
build.

Thanks,
cody

Hum don't you think it should be better to include all standard module?
I mean, if people don't want to install python and source version, we should 
provide
them at least the basic python distribution no?
This can be source of bug for other plugins that are hard to track and, for 
example
ipython, i can't be sure no new standard module will not be included in the 
future.

Here it improve a little the problem:

INCLUDES = ['syntax.*', 'ed_log', 'shutil', 'subprocess', 'zipfile', 'commands',
'doctest', 'os', 're', 'shlex', 'sys', 'tempfile',
            'time', 'types', 'warnings', 'md5', 'Queue', 'pydoc', 'site']
I've got a problem with 'site' package.

;_;

Tryied to remove it my code but then satrting editra blow up :)
It seems taht site needs to be included anyway in other ipython part and can't 
be
included with py2exe...
Will check later, I'm ultra busy at work ;)

I am not so sure, I would like to keep the binary distributions as small as 
possible
so that downloads are faster and it saves bandwith on my server. Also Editra is 
not a
python editor so much as it is a general purpose code editor so many users are 
not
python devs and don't need all kinds of extra unused packages shipped with it.

I would think that most python devs would use the source version of Editra as it
provides better usage for autocompletion and what not since it can access the 
python
and all installed libs on the system and not just the ones bundled into the 
binary
package but the majority of downloads that come directly off my server are for 
the
binary packages so its hard to tell.

I have some plans to improve the plugin manager to allow for dependancy 
tracking and
installation of components through the setuptools mechanisms that will remove 
the
need of having to bundle packages into the plugins directly. These plans 
however are
a ways down the path on my schedule so not too sure on details nor timeframe 
yet.

So the short answer is for now I only want to bundle what is required into the
binaries. Also, I am not even sure if py2exe has an option for bundling 
everything or
not. So if we need a couple of modules for Ipython to work I am fine with 
adding them
to the INCLUDES of py2exe/py2app.

Spent a few minutes doing some debugging. There are all kinds of unused imports 
in
ipyshell_nonblocking.py and many of them are the same that are showing up on the
erors you are getting. Simply remove them. There are still some issues with 
loading
the plugin after this but this is all I had time to check for now.

Also there should be no need to add (sys, os, re, time) to the INCLUDES as they 
are
used throughout Editra and are included in the build by default already.

You might want to consider installing and running pylint on your code it can 
help allot.

Ok, I did some more work on this, this evening.

updated to Ipython 0.9.1

The only problem now is still the import errors when running a binary version 
of Editra.

It seems that the problem is caused by how IPython does its imports.

Many of the modules inside of IPython do something like this:

from IPython import Release

All of these lines are causing the problem. Changing them to relative imports

import Release

Fixes the problem but there are so many and it doesn't work for subpackages 
that need
to import something from the module a level above.

So I am a bit stumped right now. The only thing that I think will fix this is to
somehow find the path to the package in the egg and adjust sys.path. But I 
think that
that is now the only issue left.

Closing this issue as out of date as the ipyshell plugin is not currently active
