hgweb: allow viewing diffs against p1 or p2 for merge commits (
issue3904)
This adds UI portion of the feature that has resided in mercurial since 2012.
Back then the interface was added together with the code, but was shortly
backed out because it was deemed "not ready". Code, however, stayed.
For the original feature and its implementation, see
issue2810 and
d605a82cf189.
In short, the backed-out interface had two outstanding issues:
1. it was introducing an entirely new term (baseline) and
2. it was present on every changeset's page, even for changesets with 1 parent
(or no parents), which didn't make sense
This patch implements a hopefully better interface because:
1. it uses the usual terms (diff) and
2. it only shows up when there actually are 2 parents.
namespaces: remove templatename method on the namespaces object
Now that there is an object for each individual namespace, we use the
templatename property on that object instead of the method on the collection of
namespaces.
namespaces: remove names method on the namespaces object
Now that there is an object for each individual namespace, we use that instead
of the method on the collection of namespaces.
templatekw: update namespace calls
Previous patches changed the namespace api to be more of an object-oriented
approach. This patch updates the template function to use said api changes.
namespaces: add __getitem__ property
Since the namespaces object uses an underlying (sorted) dictionary to store the
namespaces, it makes sense to expose this to naturally gain access to those
namespaces.
cmdutil.jsonchangeset: properly compute added and removed files
jsonchangeset._show() was computing the reverse status of the current
changeset. As a result, added files were showing up as removed and
removed files were showing up as adds.
There were existing tests for this code and they were flat out wrong.
