New setup script for pyswap

[Daniel Berenguer]

I've just changed the internal package structure of pyswap in order to
work with the new install script. No more need to manually alter
PYTHONPATH. Now all we have to do is enter the pyswap directory and
run the following command:

python setup.py install

Under Linux you'll probably have to run the command as superuser.

So pyswap is now at version 0.1.3
As result, SWAPdmt and lagarto switch to 0.1.3 and 0.0.2 respectively.

After updating both pyswap and pyswapdmtgui I get the following error
when try to run pyswapdmtgui.py .
Of course is a windows system :).

Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\pyswapdmtgui\src
\pyswapdmtgui.py", line 34, in <module>
settings = os.path.join(os.path.dirname(__file__), "config",
"settings.xml")
NameError: name '__file__' is not defined

No luck running it from command line either.
Does __file__ needs to be defined for windows environment?

[Daniel Berenguer]

Mmmm... are you running pyswapdmtgui.py with py2exe? Anyway, I've
replaced "__file__" by "sys.argv[0]" in the main script. That should
solve the problem.

[Iulian-Marius]

I'm running it from command line.
After updating the files via svn i'm getting the following error:

Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\pyswapdmtgui\src

\pyswapdmtgui.py", line 38, in <module>
manager = SwapManager(settings)

line 126, in __init__
self.browser_panel = BrowserPanel(self, self.server.network.motes)
AttributeError: 'NoneType' object has no attribute 'network'

This is strange as the first version worked just fine. Is windows
related or python related (maybe need version 3+ or something...).

[Daniel Berenguer]

Well, I have not obviously done many tests on Windows :-(
I need to trace the problem on my Windows machine...

[Iulian-Marius]

Is there any way to go back to a previous version ?
I can only find revision 496 on svn.

[Daniel Berenguer]

The easiest way is to checkout a new copy (after renaming or deleting
your currernt one) as follows:

svn checkout -r 485
http://panstamp.googlecode.com/svn/trunk/python/pyswap
/path/in/your/computer

where 485 is the revision number before applying the latest changes.

Otherwise, I'm currently trying to debug the problem on a Windows XP
PC so I hope to come back with results soon.

[Daniel Berenguer]

OK, found the problem. I don't know why but the tarfile module is
unable to uncompress devices.tar.gz under Windows. This tar.gz
contains all device definition files and is automatically downloaded
from the Web. Until I find a valid workaround, I recommend all Windows
users to set <devices><update> to false in config\settings.xml. Then,
copy your local copy of the "devices"folder to config\ or set
<devices><local> accordingly.

[Daniel Berenguer]

Solution found!

Windows seems to manage tar.gz files incorrectly, maybe for the double
compression format. Switched to single tar compression.

"svn update" pyswap and then do the same with pyswapdmtgui or change
"devices.tar.gz" to "devices.tar" in <settings><devices><remote>

Pyswap workin great now !!
And the fun begins... When i try to launch Lagarto I get the same
error in regards to _file_ nod defined:

Traceback (most recent call last):

File "C:\Python27\Lib\site-packages\lagarto\lagarto-swap\lagarto-
swap.py", line 42, in <module>

settings = os.path.join(os.path.dirname(__file__), "config",
"settings.xml")
NameError: name '__file__' is not defined

I've replaced "__file__" by "sys.argv[0]" - necessary for windows by
the looks of it.
That seemed to solve it.

Now I get the following error:
SWAP server starting...
Downloading Device Definition Files
Unable to update Device Definition Files
SWAP server is now running...

What I get from it is that the program is looking for /dev/ttyUSB0:
as serial port.
I'm using com6 as serial port and my pyswap works fine and remembers
this setting, for some reason lagarto doesn't :(.
The second part of the log.... no idea if has the same cause or not.
Windows... :(

[Daniel Berenguer]

Hi Iulian.

Whilst I look into this issue, you may want to configure your serial
port by hand from lagarto/lagarto-swap/config/serial.xml. That should
work. SWAPdmt and lagarto-swap use different configuration files.

[Daniel Berenguer]

BTW, thanks a lot Iulian for the reports!

[Iulian-Marius]

I'm the one that has to thank you for all your help!!!
I've changed the com port settings...
The result:

SWAP server starting...

It is somehow a victory!!!
But the server is not working :(.
No luck when i try to access localhost:8001.

[Daniel Berenguer]

Hi Iulian!

I've uploaded a new version of lagarto that solves the problems you
found... except for the "Unable to update Device Definition Files"...
did you upgraded your local copy of pyswap? Did you install it with
"python setup.py install" again? Have you this same problem with
SWAPdmt too?

[Iulian-Marius]

Ok, after the update and python setup.py install is working.
When i try to connect to localhost:8001 it requires a username and
password. I know it sound ridiculous but i have no idea of the
username and password or how to change it.:(
The good part is that is working... :)

[Daniel Berenguer]

I uploaded for some reason my own httpauth file. Just delete
lagarto/lagarto/security/httpauth. That should let you get a clean
connection with no user account.

[Iulian-Marius]

Deleting it is not going to fix it.
Just tried now and this is the error report:

Maybe a default error should fix it.

[Daniel Berenguer]

Sorry Iulian, I got the same error here when I tried without httpauth.
I was uploading the new code that corrects this when I saw your
message. You just need to upgrade lagarto.

[Iulian-Marius]

The new version of lagarto is working on windows.
I've start playing with binouts.ino.
The pwm outputs are working fine but for I/O outputs i get this error:

Also noticed that my CPU usage is aroun 50% for pythonw.exe, mem usage
13.700k.
I know that an atom single core @ 1600mhz is not much (or less to zero
this days) but this looks very strange, especially that
lagarto should run on something as light as rasberryPi.
Is windows again the one that is causing the pain in the...CPU?

[Daniel Berenguer]

You mean that Lagarto-SWAP can control the PWM outputs but not the
ON/OFF ones? Does the problem appear on a specific output? I'll try to
reproduce the error ASAP.

As for the CPU consumption I don't know what to say... I did some
tests on an old Linksys NSLU2 and Lagarto-SWAP worked just fine but
some of the latest changes may have altered the performance. I'll try
to check this too.

Thanks Iulian!!

[Iulian-Marius]

Yes, PWM works fine, ON/OFF not working- none of them.
It says that list index is out of range...

[Daniel Berenguer]

Thanks Iulian.

[Daniel Berenguer]

Solved the problem. This was due to a an incorrect byte position in
binouts.xml. No need to manually update your definition files if you
have the automatic update enabled.

Thanks again for the hunting Iulian.

[Daniel Berenguer]

A small change has been added to pyswap that solves the CPU usage problem.

Thanks Iulian!
