Summary:
This hardcodes several perftweaks configs that have been enabled for major FB
repos for months:
[perftweaks]
disablebranchcache = True
disablebranchcache2 = True
disableresolvingbranches = True
disableupdatebranchcacheoncommit = True
Practically, this means the branchmap is now just `{'default': heads}`. (i.e.
there are no named branches other than `default`), and branchcache is removed
(i.e. `.hg/cache` does not exist without clindex or in-repo tags).
This diff only makes easy-to-verify logic changes by assuming the configs and
removing dead code. Things can be further cleaned up. They will be done by
upcoming changes.
Most test changes are due to the fact that `.hg/cache` is no longer created.

Namespaces are basically generic many-to-many mapping between some

|
|
jamming things into tags or bookmarks (in extension-land) and to simplify
|
|
internal bits of mercurial: log output, tab completion, etc.
|
|
|
|
More precisely, we define a mapping of names to nodes, and a mapping from
|
|
nodes to names. Each mapping returns a list.
|
|
|
|
Furthermore, each name mapping will be passed a name to lookup which might
|
|
not be in its domain. In this case, each method should return an empty list
|
|
and not raise an error.
|
|
|
|
This namespace object will define the properties we need:
|
|
'name': the namespace (plural form)
|
|
'templatename': name to use for templating (usually the singular form
|
|
of the plural namespace name)
|
|
'listnames': list of all names in the namespace (usually the keys of a
|
|
dictionary)
|
|
'namemap': function that takes a name and returns a list of nodes
|
|
'nodemap': function that takes a node and returns a list of names
|
|
'deprecated': set of names to be masked for ordinary use
|

'builtin': bool indicating if this namespace is supported by core
