[pycsw-devel] Running on Windows 2008 Server IIS7

Thu Mar 15 01:54:17 EDT 2012

Yep, that was it.  Thank you very much for solving that one.

It seems I have another issue.  With tester http://dev.insideidaho.org/pycsw/tester/ I can get a GetCapabilities response only if in default.cfg "xml_pretty_print=false".  If I change that to ""xml_pretty_print=true" I don't get anything in the response text box.  

If I try to go to:
http://dev.insideidaho.org/pycsw/csw.py?service=CSW&version=2.0.2&request=GetCapabilities

I get this with "xml_pretty_print=false":
This page contains the following errors:
error on line 3 at column 27: xmlns:dc: 'http://purl.org/dc/elepabilities xments/1.1/' is not a valid URI
Below is a rendering of the page up to the first error.

I get this with "xml_pretty_print=true":
This webpage is not available
The webpage at http://dev.insideidaho.org/pycsw/csw.py?service=CSW&version=2.0.2&request=GetCapabilities might be temporarily down or it may have moved permanently to a new web address.
Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error.

Is there something in default.cfg that I might have incorrect?  

Thank you for your patience working through this with me.

Bruce: thanks for the info.  Any chance that there are multiple Python installs?  You have sqlalchemy from the command line, but is it the same Python being used by IIS?  Where is sqlalchemy installed?  Perhaps you can set the PYTHONPATH environment variable to this directory?

Here is the error returned from your script: HTTP Error 502.2 - Bad GatewayThe specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are "Traceback (most recent call last): File "C:\criticalApplications\console\pycsw\pycsw-1.0.0\test3.py", line 4, in <module> import sqlalchemy ImportError: No module named sqlalchemy ". But, in a python shell if I request the version I get '0.7.5' though as shown here: Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on win32Type "copyright", "credits" or "license()" for more information.>>> import sqlalchemy>>> sqlalchemy.__version__'0.7.5'>>>  And, I see "sqlalchemy' show up in the list when I use "help('modules')". Ideas on how best to proceed? -Bruce  From: Tom Kralidis [mailto:tomkralidis at hotmail.com]

Bruce: thanks for the info.  I'm wondering about the sqlalchemy issue, and the fact that it's not found is causing an error right away.  Can you try, as a cgi script:

#!/Python27/python -u

import os
import sqlalchemy

print 'Content-type:text/plain\n\n'

for k,v in os.environ.iteritems():
    print '%s -> %s' %(k,v)

This should run fine assuming sqlalchemy can be found in your environment in IIS, and we can see what environment variables IIS is working with at runtime.

I don't have an IIS environment, so if you can try, that would be great.  We can then figure out a way to patch the IIS environment variables in the codebase.

Thanks

..Tom

I added system added environment variable for 'HTTP_HOST' and 'REQUEST_URI'.  That appears to have gotten me further along.  But, I have another hurdle to clear it appears.  See below. I've got simple test python scripts working in the same web directory as cws.py.  They can be seen here:http://dev.insideidaho.org/pycsw/test.py and http://dev.insideidaho.org/pycsw/test2.py.  So, I think (fingers crossed) that I have the web server configured correctly but maybe I am overlooking something. When I use the pycsw tester to try make a GetCapabilities request I get a 502 error.   Pycsw tester is here: http://dev.insideidaho.org/pycsw/tester/index.html When I run pycsw on the localhost machine I get this response with more details: #############################BEGIN RESPONSE################################# <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>IIS 7.0 Detailed Error - 502.2 - Bad Gateway</title> <style type="text/css">  </style>  </head> <body> <div id="header"><h1>Server Error in Application "DEFAULT WEB SITE/PYCSW"</h1></div> <div id="server_version">Internet Information Services 7.0<BR></div> <div id="content"> <div class="content-container">  <fieldset><legend>Error Summary</legend>   <h2>HTTP Error 502.2 - Bad Gateway</h2>   <h3>The specified CGI application misbehaved by not returning a complete set of HTTP headers.  The headers it did return are &quot;Traceback (most recent call last):  File &quot;C:\criticalApplications\console\pycsw\pycsw-1.0.0\csw.py&quot;, line 34, in &lt;module&gt;    from server import server  File &quot;C:\criticalApplications\console\pycsw\pycsw-1.0.0\server\server.py&quot;, line 40, in &lt;module&gt;    import config, fes, log, profile, repository, util  File &quot;C:\criticalApplications\console\pycsw\pycsw-1.0.0\server\repository.py&quot;, line 33, in &lt;module&gt;    from sqlalchemy import create_engine, desc, funcImportError: No module named sqlalchemy&quot;.</h3>  </fieldset> </div> <div class="content-container">  <fieldset><legend>Detailed Error Information</legend>   <div id="details-left">    <table border="0" cellpadding="0" cellspacing="0">     <tr class="alt"><th>Module</th><td>CgiModule</td></tr>     <tr><th>Notification</th><td>ExecuteRequestHandler</td></tr>     <tr class="alt"><th>Handler</th><td>Python</td></tr>     <tr><th>Error Code</th><td>0x00000001</td></tr>         </table>   </div>   <div id="details-right">    <table border="0" cellpadding="0" cellspacing="0">     <tr class="alt"><th>Requested URL</th><td>http://dev.insideidaho.org:80/pycsw/csw.py</td></tr>     <tr><th>Physical Path</th><td>C:\criticalApplications\console\pycsw\pycsw-1.0.0\csw.py</td></tr>     <tr class="alt"><th>Logon Method</th><td>Anonymous</td></tr>     <tr><th>Logon User</th><td>Anonymous</td></tr>         </table>    <div class="clear"></div>   </div>  </fieldset> </div> <div class="content-container">  <fieldset><legend>Most likely causes:</legend>   <ul>     <li>The CGI process was shut down or terminated unexpectedly before it finished processing the request.</li>                 <li>The CGI process has a flaw and does not return a complete set of HTTP headers.</li> </ul>  </fieldset> </div> <div class="content-container">  <fieldset><legend>Things you can try:</legend>   <ul>     <li>Check the event logs on the system to see whether the CGI process is shutting down unexpectedly.</li>                 <li>Troubleshoot the CGI application to determine why it is not sending a complete set of HTTP headers.</li> </ul>  </fieldset> </div>   <div class="content-container">  <fieldset><legend>Links and More Information</legend>   This error occurs when the CGI process handling the request exits before it finishes sending the response to IIS.   <a href="http://go.microsoft.com/fwlink/?LinkID=62293&amp;IIS70Error=502,2,0x00000001,6002">View more information &raquo;</a><BR>     </fieldset> </div> </div> </body> </html> #############################END RESPONSE#################################  Note that "sqlalchemy' show up in the list when I use "help('modules')"  It seems like the crux of the issue is that IIS7 doesn't like the way the HTTP headers being returned by the pycsw script(s).  Maybe a syntax issue?  I'm not sure.  I'm definitely no expert.  Since I can run the test.py scripts I'm hoping that the web server is configured properly.  If not I'm not quite sure where to look at this point.  But, maybe it is still an IIS7 configuration issue. Ideas on how to troubleshoot this or get it working?  Thanks much! -Bruce  From: Angelos Tzotsos [mailto:gcpp.kalxas at gmail.com]

Yes, it seems that this issue is Windows specific. The "HTTP_HOST" variable is not set in the environment variables.

Please try this from a Python console:

import os
os.environ

and send the output.

Thanks,
Angelos

Did you try the windows path like c:\path\to\pycsw ?
