That said, I didn't see any indication of what I consider to be a critical failure in PyPI: No dependency metadata prior to downloading the package.<br>

+1. I want to be able do list all the packages an easy_install run will<br>
download without running it. Something like the "-s" option of apt-get.<br>
In addition, I want this information to be available programmatically (ie<br>
with a good api, not something that expects to be called from the command<br>
line) to be able to use it to build dependency graphs, generate conflicts<br>
list, or simply tell me that I have requested something that is<br>
impossible.<br>
<br>
There is nothing that I hate more than easy_install failing after having<br>
half-installed a package because of a missing dependency. This is one of<br>
the reasons I am never too happy when I have to run easy_install.<br>

FWIW, pyinstall can collect all the packages before installing any of them. You do have to download all packages, though, as that's the only way to get the metadata.</blockquote><div>is a "simple catalog "db storage for metadata like /usr/ports/ on freebsd a bad idea ?</div>
<div>the idea is to not download all packages to get the metadata, but just query the catalog/db</div><div><br></div><div>Cheers,</div><div><br></div><div>Jean-Philippe</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
