Re: OperatingSystem library and network share

[Bulkan]

Hi Wayne,

Try using this sort of quoting for the nextwork path

Count Files In Directory                  \\\\localhost${/}temp

Cheers

Hi there,

We migrated a bunch of robot tests between machines and now a test which tries to access a network share fails. 

I can reproduce this locally with a simple test. Should I be able to do something like?

Count Files In Directory                  \\localhost\temp

or  

Count Files In Directory                   ${/}${/}localhost${/}temp

Note that I can reach this network share through the file browser, it runs as the same user, and it works with a local path.

 The only thing that I think could have changed when migrating would be the robot framework version (the shared path remains the same).

With much thanks,

Wayne.

Hi Bulkan,

Thanks for your suggestion, but it still doesn't work for me. Did you try it?

I had two colleagues run the same test. On one machine it passed and on another it failed. They were both running windows XP, I am running windows 7 and the server previously mentioned is running windows 7. 

The two failures occurred on latest versions of robot framework, python, jython (we run tests through Maven), and robot selenium library (though this should have nothing to do with it). I then tried versions which matched the machine which passed the tests, and still to no avail. We tried a share on localhost as well as the original network path on the database server.

Any other suggestions?

Thanks,

Wayne.

Before executing os.listdir, the keyword verifies that the specified
directory exists using os.path.isdir. It seems that on your system
that check fails. Could you try that on the interpreter? You could
actually test the following combinations to see could the difference
be does the path end with a path separator or not, or is it a byte
string or Unicode:

os.path.isdir('\\\\localhost\\temp')
os.path.isdir('\\\\localhost\\temp\\')
os.path.isdir(u'\\\\localhost\\temp')
os.path.isdir(u'\\\\localhost\\temp\\')

Btw, are you running your tests using Python or Jython? If the latter,
you should actually run the tests on Jython interpreter.

Thanks Pekka.

In jython os.listdir returns the folder contents but os.path.isdir returns False.

In python os.listdir returns the folder contents and os.path.isdir returns True.

I guess this points to the direction of the problem. I am currently running python 2.7.2 and jython 2.5.1. I could try different jython versions when at work tomorrow, though I was pretty sure that my colleague and I had the same versions.

Sounds like there is some kind of a weird bug in Jython.

Did you find any more information regarding to this? If not, below are
few more questions that might help us to understand what's going on:

- Does your path contain non-ASCII characters?
- When using Jython directly, did you use Unicode or byte string (i.e.
u'path' or 'path')?
- Does os.path.exist(path) work with Jython?
- What does os.stat(path) return?

Because it seems that os.listdir itself works and the problem is in
os.path.isdir, we could consider changing List Directory keyword to
just use the former without verifying that the directory actually
exists before. That would cause slightly worse error messages with
non-existing directories, but that's pretty minor problem compared to
the whole keyword not working. It would be much better to understand
the actual root cause and possibly fix or workaround it, though,
because in the current situation many other OperatingSystem keywords
(e.g. Directory Should Exist) will not work for you anyway.

Hi Pekka,

I logged a Jython issue and am waiting to hear back: http://bugs.jython.org/issue1975. 

I've tried the latest version of jython as well as the version for which it works on my colleagues machine. For now we wrote a quick java keyword to replace the os keyword which doesn't work for some of our systems.

In regards to your questions:

- Does your path contain non-ASCII characters? No, the path is \\localhost\temp
- When using Jython directly, did you use Unicode or byte string (i.e.u'path' or 'path')? This does not make a difference in jython, but both work in python
- Does os.path.exist(path) work with Jython? No (but yes in python) See below
- What does os.stat(path) return? It says that there is no such file or directory. See below

Thanks again,

Wayne.

Hi,

robot framework: Copy file to the network shared fodler: 

It works for me:

OperatingSystem.File Should Exist     \\\\192.168.1.1\\storage\\*.tar.gz
