AttributeError: 'HTTPMessage' object has no attribute 'getheaders'

This bug is from the latest codeline of distribute ( from tarek's branch). It should be fixed in there. Following the recent changes in cpython line, I saw that distribute was monkeypatching httplib and a fix was made in cpython, perhaps the same should be ported here.

It will be observed, whenever the setup tries to download the package from pypi or any other remote repo.

I'm getting this, too:

AttributeError: 'HTTPMessage' object has no attribute 'getheaders'

My quick (and dirty) fix was to edit package_index.py, comment out line 583, adding my own, like so:

                #content_length = headers.getheaders("Content-Length")[0]
                content_length = fp.getheader("Content-Length")[0]

this is blowing up our jenkins server all the sudden. we're getting it with 0.6.18...

so, the fix is:

diff --git a/setuptools/package_index.py b/setuptools/package_index.py
--- a/setuptools/package_index.py
+++ b/setuptools/package_index.py
@@ -580,7 +580,7 @@
             size = -1
             if "content-length" in headers:
                 # Some servers return multiple Content-Length headers :(
-                content_length = headers.getheaders("Content-Length")[0]
+                content_length = headers.get("Content-Length")
                 size = int(content_length)
                 self.reporthook(url, filename, blocknum, bs, size)
             tfp = open(filename,'wb')

This works with all flavors of this class.

Preparing 0.6.19 now

make sure we don't use getheaders(). get() works for all py versions - fixes #206

→ 611910892a04

Please try out 0.6.20 -- just released

its building now (on 0.6.19 is that what you meant ?) - its into the tests so its fixed, thanks !
