status: cache dirstate status in _dirstatestatus() Since it's only the dirstate status we cache, it makes more sense to cache it in the _dirstatestatus() method. Note that this change means the dirstate status will also be cached when status is requested between the working copy and some other revision, while we currently only cache the result if exactly the status between the working copy and its parent is requested.

localrepo: add ignoremissing parameter to branchtip Previously, in the namespaces api, the only caller of branchtip was singlenode which happened to raise the same exception that branchtip raised: KeyError. This is a minor change but will allow upcoming patches to use repo.branchtip to not raise an exception if a branch doesn't exist. After that, it will be possible for extensions to use the namespace api in a stable way.

namespaces: add method to return a list of nodes for a given name This is a helpful method that some extensions can make use of (e.g. for custom revsets); currently not used in core.

namespaces: add test for log Now that we have enough features in the namespaces api, we add a test for it.

log: use new namespaces api to display names The only caveat here is that branches must be displayed first due to backwards compatibility. The order of namespaces is defined to be the 'update' order which, unfortunately, is not the same as log output order. It's worth mentioning that the log output is still translated the same as before since we are formating our strings the same way: # i18n: column positioning for "hg log" _("bookmark: %s\n") % bookmark becomes tname = _(("%s:" % ns.templatename).ljust(13) + "%s\n") % name when name == 'bookmark'. The ljust(13) keeps the strings and whitespace equal. Adding a new namespace is even easier now because the log output code doesn't need to change. A future programmer would just need to add the string to the corresponding .po file (which is the same as they would have had to do previously).

tests: add a i18n translation test for log output Upcoming patches will change the way that log output is generated so we add a test to ensure that the words 'branches', 'bookmarks', and 'tags' are still translated.

filectx: fix annotate to not directly instantiate filectx 28a302e9225d changed basefilectx.annotate() to directly instantiate new filectx's instead of going through self.filectx(), this breaks extensions that replace the filectx class, and would also break future uses that would need memfilectx's.
