Find out version of app in remote API shell?

[Felix E. Klee]

Suppose I run the remote API shell as follows:

$ python some_path/remote_api_shell.py -s 1-5-3.example.appspot.com

How do I find out the version number of the app from within the shell?

(in this case: 1-5-3)

I reposted this question now on:

google-appe...@googlegroups.com

Seems to be more appropriate.

import os
os.environ['CURRENT_VERSION_ID']

The key "CURRENT_VERSION_ID" is *not* available in the remote API shell:

s~example> import os
s~example> os.environ['CURRENT_VERSION_ID']
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "C:\Programme\Python25\lib\os.py", line 433, in __getitem__
return self.data[key.upper()]
KeyError: 'CURRENT_VERSION_ID'

I usualy have a handler on the server that does show the current running version. I'm more used to write Java code, but this handler may help you:

class CurrentVersion(webapp.RequestHandler):

    def get(self):

        self.response.headers["Content-Type"] = "text/plain"

        self.response.out.write(os.environ["CURRENT_VERSION_ID"])

If you map it "/version" you can then access it with urllib on a client-side code:

version = urllib2.urlopen("http://example.appspot.com/version").read()

I'm not sure if the remote api environment provides such funcionality, but they may do ... 

Hope this help,

If I had the URL, then I would already be all set. It includes the
version!

Remember:

$ python some_path/remote_api_shell.py -s 1-5-3.example.appspot.com

The question is: How do I get the URL that was entered on the command
line when starting the remote shell?

Hi,

You could try to iterate through the sys.argv list, and find the argument next to the "-s" one.

Oops, sorry, I misunderstood your question :) .. Ernesto's answer may be the only one available to you then: explore sys.argv to check if a version was specified. But this won't work if you start with a custom domain instead of a version-based domain.

Good point! Try this too (I won't have access to appengine until the night):

from google.appengine.api import app_identity

app_identity.get_application_id()

Reports the app ID, not the version. For "1-5-3.example.appspot.com"
that's:

Thanks for the suggestion! Had that already in mind as a fall-back
solution. However, was hoping for something simpler and more reliable.

Finally, I found a solution:

parser = optparse.OptionParser()
parser.add_option('-s', '--server', dest='server')
(options, args) = parser.parse_args()
options.server.split('.')[0]
