EasyInstall 0.4a1: now with PyPI autodownload

I've just released a new version of EasyInstall, that supports automatic 
package location via PyPI; installing a package can now be as simple as:

     easy_install "SQLObject>=0.6"

There are many new options and features related to this; see the 
EasyInstall home page for more information:

     http://peak.telecommunity.com/DevCenter/EasyInstall

For the benefit of the PyPI maintainers, here is a summary of EasyInstall's 
fairly minimal assumptions about PyPI's current behavior, assuming that 
"base-url" is the root URL of the package index:

    * Going to "base-url/SomePackage" produces an HTML page that either has 
a title containing "Index of Packages" and links to zero or more pages for 
specific versions, or else it is a single-version package page.

    * Single-version package pages may have a home page and download URL 
link, each of which occurs after '<th>Home Page' and '<th>Download URL' 
respectively, if present.

    * Going to "base-url/" (note trailing '/') produces an HTML page 
containing links to all active versions of registered packages

    * Links to package pages always have URLs of the form 
"base-url/SomePackage/itsVersion" - i.e., exactly two path parts following 
the base URL, with no query strings, parameters, fragments, etc.

EasyInstall should continue to work with PyPI if these assumptions continue

pypi xmlrpc

I heard a rumor (on here i think) that there was some xmlrpc support 
added to pypi at pycon2005. Is there any documentation on the functions 
you can call and the urls? Is the code available for perusal in svn or 
cvs?

They added what we gave them, which wasn't much ;)  Here's the functions 
currently available:

def echo(store,*args):
     return args

def index(store,*args):
     spec = { }
     return store.query_packages( spec )

def search(store,*args):
     term = args[0]
     spec = { 'name' : term, 'summary' : term }
     return store.query_packages( spec, andor='or' )

Usage:

 >>> import xmlrpclib
 >>> pypi = xmlrpclib.ServerProxy('http://python.org/pypi')
 >>> pypi.search('pypi')
({'info': ['pypi', '2004-03-01', 'PyPI is the Python Package Index at 
http://www.python.org/pypi'], 'cols': ['name', 'version', 'summary'], 
'cols_d': {'version': 1, 'name': 0, 'summary': 2}}, {'info': ['pypi', 
'2004-03-02', 'PyPI is the Python Package Index at

PyPI upload problem

I'm having problems with uploading Windows installer files (i.e.
those generated by "python setup.py bdist --formats=wininst") to PyPI.

I'm uploading the file through the web interface (from the URL 
http://www.python.org/pypi?:action=files&name=ll-xist&version=2.10) not 
via "python setup.py upload".

I get the following error:

----
Error...

There's been a problem with your request

exceptions.NameError: global name 'safe_zipnames' is not defined
----

Please CC any replies to me, as I'm not on the list.

Bye,

 From a viewpoint of a human user, yes, that can be expected. We will in 
fact expect the person to google for it if it is not in PyPI. From a 
viewpoint of a tool, that may be too tricky.

Another thing in my radar is that package names may change. I was 
reading an article on O'Reilly ONLamp.com, "Using PySOAP" by Cameron 
Laird, written on 06/14/2001 
(www.onlamp.com/pub/a/python/2001/06/14/pysoap.html). When reading it, I 
realise that instead of PySOAP, it should be SOAPpy. Of course, I do not 
know if SOAPpy was named as PySOAP back then, but you see my point......

Presumably the tool is invoked by a user, and therefore user feedback is 
possible?

This is something that I hope will be minimised by having the "authoritative" 
name database in PyPI.

PyPI upload doesn't support eggs?


I can't seem to convince the "upload" command to send egg distributions to 
PyPI.  I'm using the CVS head version of "upload", and modified bdist_egg 
to add the necessary information to distribution.dist_files, but attempting 
to upload gives this response (using --show-response):

Submitting dist\setuptools-0.5a4-py2.3.egg to http://www.python.org/pypi
Upload failed (500): There's been a problem with your request
--------------------------------------------------------------------------- 
Erro
r...

There's been a problem with your request

exceptions.ValueError: invalid distribution file 
-------------------------------
--------------------------------------------

Any suggestions?

Re: PyPI upload doesn't support eggs?


I just tried doing the upload via the web interface, and got the same 
error.  It appears that PyPI doesn't support uploading eggs, which is 
surprising because I could've sworn that the sprinters at PyCon said they 
were putting eggs on the list of allowed filetypes.  But I just found the 
appropriate PyPI source code, and '.egg' isn't on the list of allowed file 
extensions, so I'll go ahead and file an RFE for this.

.egg media type? (was: PyPI upload doesn't support	eggs?)

On an almost related note, what should the MIME content/media type be  
for serving egg files via HTTP? It may be advantageous to use  
"application/zip" [1].

A derivative like "application/egg+zip" would allow the media type to  
be associated with easy_install or other handlers while preserving  
the base media type information (although I'm not completely clear on  
whether derivatives require registration).
