I'm writing an application to maintain a mirror of PyPI package metadata, and I'm trying to understand the changelog data. In particular, I've not been able to find anything that lists the valid values for the "action" element of a change record. Looking at what's available if I just query the database, I get: pkg rename from XXX pkg, version remove pkg remove Owner XXX pkg remove Maintainer XXX pkg update hosting_mode pkg, version update list,of,fields pkg, version new release pkg add Owner XXX pkg add Maintainer XXX pkg, version add url XXX pkg, version add XXX file YYY But I don't think that can be all (for a start, there's no "add a new package" - unless the "new release" action can have a version of None, which I haven't seen) Is there a full list anywhere? I had a brief look at the Warehouse code, but short of tracking down all the places journal entries are stored, I couldn't see a way of finding out. Actually, given that the XMLRPC API only lets you get the releases of a package, the release data for a given release or a list of the url data for a given release, there's not really much need for me to worry beyond that level (so, for example, add url and add file both just mean "grab the url data and replace what's there", and "update" just means "replace the package data but don't bother refreshing the urls"). Does that sound reasonable? Thanks, Paul
