Crash while spawnin upload process on Windows 7

[marandus]

I installed EMDU on Windows 7 x86_64 following the instructions on your GitHub page. It starts up fine but then crashes when it tries to spawn the upload process stating it cannot find the emdu_console module.
I start EMDU using the following command (the Python directory is in my PATH):
python C:\Python27\Scripts\emdu_console

Error message:
2013-06-19 23:50:04,265: Got scan_endpoint http://upload.eve-emdr.com/upload/
2013-06-19 23:50:07,680: Spawning upload process.

I don't run under Windows myself, so I don't think I'll be much help here. I'll definitely accept a pull request if you are able to figure out what's going on, though.

I've run into this same error and done some digging around. It appears to be a problem with multitasking under python on windows and pickling. I'm a little uncertain on these issues being a noob coder so hope this helps.

[hitchhiker54]

Ok, well I don't know why it worked, but under Windows 7 I renamed emdu_console to emdu_console.py in the bin folder of -master and ran it, seems to be going just fine :)

[marandus]

The above seems to work with the file in the bin folder, but it does not work im you do the same to the emdu_console script which is installed in the Scripts directory of the Python install.

[hitchhiker54]

Progress :) There seems to be a build error with the Windows package. Running either the full emdu_console.py or the package call version that's left in /scripts gives error

emdu_console.py run in python27/scripts gives error
The file build\bdist.win32\egg\pkg_resources.py could not be opened

in 'Eric' debug mode.

As a further test I unpacked the egg and copied build folder into \Lib\site-packages

the 1k emdu_console.py package caller script still fails but the full 3k emdu_console.py from -master archive works fine again.

[gtaylor]

I'm not sure how to proceed with this one, as I live in Linux land 95% of the time. If you know of a way we can fix this without impacting the Linux/Mac OS users, I'm all ears.

[hitchhiker54]

So... I spent some time this morning avoiding work and looking at this; nothing on stackoverflow seemed to be relevant to the issue. Occam's razor came to the fore and i killed my emdu install as generated by d/l master archive and running setup.py. I then reinstalled with :

pip install git+https://github.com/gtaylor/EVE-Market-Data-Uploader.git

ran python emdu_console - back to the 'module not found : emdu_console' - ok, so added .py to it in scripts et voila! It works! -performs a happy dance-

Basically Windows is a problem :( The simple solution I guess in this case is just to let M$ users know that they need to rename the file to /python27/scripts/emdu_console.py and install git command line to run from command console as an added requirement.

[gtaylor]

What happens if you add your Python scripts dir to your $PATH and run emdu_console as a normal command, ie: emdu_console instead of python emdu_console?

[hitchhiker54]

C:\Users\Me>emdu_console
'emdu_console' is not recognized as an internal or external command,
operable program or batch file.

Windows always needs a file extension of some sort to understand how to handle a file.

[gtaylor]

I think pip figured this out somehow. May be worth looking at how they do
it.

I've thrown up a red herring here :( When I reinstalled via 'pip install git+...' it just installed the source into site-packages instead of building an .egg file. The original issue has resumed.

The file left in /Scripts reads :

#!C:\Python27\python.exe

EASY-INSTALL-SCRIPT: 'emdu==0.1','emdu_console'

requires = 'emdu==0.1'
import pkg_resources
pkg_resources.run_script('emdu==0.1', 'emdu_console')

All well and good, the emdu-1.0-py2.7.egg/EGG_INFO/scripts/emdu_console is there and starts to run. This is apparently also where it fails as the imp_findmodule etc errors come up. Running the full emdu_console from here fails as before as well. Somewhere the .egg bound library is forcing a reference to this .egg bound script and failing terribly?

[hitchhiker54]

Ok to answer my own question :) I removed the emdu_console from the.egg including it's directory and again the same error no module emdu_console. A quick test with the .py extension worked this time though... so again I removed the extension - still working but only because emdu_console.pyc was still there; with no .pyc file the error returned again.

So we have a winner - however normally when I run a python script I don't get a .pyc file at all. Here my inexperience shows sadly as I'm mostly working this stuff out as it comes up.

[hitchhiker54]

gtaylor - It's possible that something is forcing the import of emdu_console, and thus the .pyc file generation and the error on windows. Can you shed any light here for me? I couldn't see any direct import in the library code and removing it from the egg setup didn't help.

[andrewpmartinez]

Still an issue in Windows (specifically 8.1 w/ Python 2.7.9). Fix is still as mentioned above:

1. Install via: pip install git+https://github.com/gtaylor/EVE-Market-Data-Uploader.git
2. Rename emdu_console to emdu_console.py in the C:\Python27\Scripts\ directory

[gtaylor]

I am debating whether to spend the time fixing this, now that we have the CREST market API.

Thoughts?

[andrewpmartinez]

I was poking around CREST just now and I didn't see a way to get actual market buy/sell orders. Just aggregated "adjustedPrice".

If CREST gets to the point where you can see buy/sell orders then Eve Market Data Uploader becomes obsolete. Right now, there are use case that are not covered; some listed here:

1. Determining supply demand at specific stations/regions
2. Determining profitable hauling ventures
3. Finding reasonable buy low/sell high deals

[gtaylor]

It's been a while since I've looked, but I think the market orders are only on SiSi right now. We've got people working on some software to feed EMDR from these APIs, but I haven't been super involved with it.

[andrewpmartinez]

I can't check SISI. I only just started playing eve a few weeks ago and apparently my credentials do not work for SISI (i.e. I wasn't in the system w/ the mirror was taken)

[hitchhiker54]

you'll have to wait till the next time the devs copy chars over. It doesn't
happen very often as I recall, but I've been on a hiatus for a while from
eve.
