[cpp-netlib-devel] r97 broken in http_branch (Linux)

From: Dean M. B. <mik...@gm...> - 2008-09-23 10:52:37

I've only now been able to run the localhost test scripts in Linux and
after trying to remedy the situation on my own, I recognize that I
don't have enough Python kung fu to deal with this.

Apparently HTTP_ALL_HEADERS is not set when the echo_headers and
echo_body script executes in Linux.

Can we fix this before I merge to trunk and release 0.3?

Can you test from a regular browser on Linux, and see whether you get
any output at all from echo_headers.py?

I wonder if it's a line-ending thing again.

Do all python scripts in the cgi-bin directory have execute permissions for
*all* users? I seem to remember that the linux version of CGIHTTPServer runs
the CGI scripts with a uid of nobody and that might create permission issues
in some cases. Also, are there any errors in the python log window?

Hopefully yes,

I think I missed why you're setting the HTTP_ALL_HEADERS environment
variable.  How is this supposed to work?

Permissions problem. Make sure that all cgi-bin scripts are world readable
and world executable. Also, all directories in their path are world readable
and executable. These scripts are accessed with a userid of "nobody" (uid
usually ~65000) so the .py files have to be executable by the "others"
permission group and the directory in which they are contained has to have
permissions for "others" to access them.

Basically you have to allow everybody to access them so that "nobody" can
execute them. Rather a bad pun, I must say... :-)

HTTP_ALL_HEADERS is being set so that we can echo the headers back to the
user in their raw form. The new http_server simply concatenates the headers
received in the raw form into an env. variable before handing over
processing to the python library's CGIHTTPServer. This env. variable is
accessed in the echo_headers.py and echoed back to the client.

I don't see how this is relevant though, it works fine with
requestinfo.py -- why shouldn't it work in echo_headers and echo_body?

I didn't mean the same line-ending issue as last time, but I figure
the parsing of HTTP_ALL_HEADERS could be thrown if I made any
Windows-specific assumptions about line endings.

requestinfo.py doesn't use HTTP_ALL_HEADERS, so that's why it could differ...

Apparently, the parsing of the headers from HTTP_ALL_HEADERS is not yet
perfect.  I hope I can find time this week to improve cgisupport.py

Obviously, HTTP_ALL_HEADERS does not give you the proper content length
through this method.  In fact, HTTP_ALL_HEADERS doesn't contain the string
"content-length".  But you can still get it with
os.environ["CONTENT_LENGTH"].

Same with content length, use os.environ["CONTENT_TYPE"].

The rest of the errors are of the same type of error.  So basically we'll
need better parsing of headers in cgisupport.py.  Basically, it would be
best to try to understand how the parsing is done in CGIHTTPRequestHandler.
There one will see that it's not as straightforward as splitting lines with
colons as a line could contain more than one colon.  I tried inserting these
lines into http_test_server.py (line 20, at the beginning of run_cgi
function):

print '********DEBUG self.headers!!!'
print self.headers
print '********END DEBUG'

The server's console output when I use Firefox to access the server is:

********DEBUG self.headers!!!
Host: localhost:8000
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.0.1)
Gecko/2008070208 Firefox/3.0.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-gb,en;q=0.5
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Connection: keep-alive

********END DEBUG

So, as we can see, Content-Type and Content-Length are obtained differently
by CGIHTTPRequestHandler.  It'd also help if one understands how the headers
are parsed in $PYTHON_HOME/Lib/rfc822.py.

Unfortunately, I'm rather pressed these days so maybe Kim or someone else
can do the improvements based on these observations.

Cheers,
Allister

This is a different set of errors than those faced by Glyn.  This requires
investigation, but unfortunately, my linux box is shot due to a driver
issue. It will take me some time to check this out. :(

This is where I get the value HTTP_ALL_HEADERS from the env vars.

Apparently the object returned from there is not a string, maybe it's
just empty?

Could you check that your http_test_server.http actually calls
http_test_server.py and not cgi_server.py? Oh! I see now, the C++
facade is not correctly updated -- it checks whether
http_test_server.py exists, but executes cgi_server.py, in the Unix
case. I'll fix that and commit.

None type indicates that the env var was empty.
