- High load for mercurial repositories with huge numbers of branches (T7108).
- In Mercurial, we resolve refs individually (one `hg` call per ref).
- Each repository update also updates all refs, which requires resolving all of them.
- For repositories with a huge number of branches,
- We don't distinguish between closed branches (a Mercurial-only concept) and open branches (T6160).
- In Git, when a branch is merged, it ceases to exist.
- In Mercurial, when a branch is merged, it still exists, it's just "closed". Normally, no one cares about these branches.
- In the low-level query, correctly identify which refs we resolve as branches.
- In the low-level query, correctly mark closed branches as closed.
- This marginally improves ref handling in general (see T7100).

Ref T4100. Ref T5595.
To support a unified "Projects:" query across all applications, a future diff is going to add a set of "Edge Logic" capabilities to `PolicyAwareQuery` which write the required SELECT, JOIN, WHERE, HAVING and GROUP clauses for you.
With the addition of "Edge Logic", we'll have three systems which may need to build components of query claues: ordering/paging, customfields/applicationsearch, and edge logic.
For most clauses, queries don't currently call into the parent explicitly to get default components. I want to move more query construction logic up the class tree so it can be shared.
For most methods, this isn't a problem, but many subclasses define a `buildWhereClause()`. Make all such definitions protected and consistent.
This causes no behavioral changes.

Ref T1460. This just barely works, but throwing it up in case any of it sounds mechanically crazy before we build integrations/UI/etc.
Specifically, these are the behaviors:
- You can mark your own draft comments as "done" before you submit them. The intent is to let reviewers mark their stuff advisory/minor/not-important before they submit it, to hint to authors that they don't expect the feedback to necessarily be addressed (maybe it's a joke, maybe it's just discussion, maybe it's "consider..").
- You can mark others' published comments as "done" if you're the revision/commit author. The intent is to keep this lightweight by not requiring an audit trail of who marked what done when. If anyone could mark anything done, we'd have to have some way to show who marked stuff.
- When you mark stuff done (or unmark it), it goes into a "draft" state, where you see the change but others don't see it yet. The intent is twofold:
- Be consistent with how inlines work.
- Allow us to publish a "epriestley updated this revision + epriestley marked 15 inlines as done" story later if we want. This seems more useful than publishing 15 "epriestley marked one thing as done" stories.
- The actual bit where done-ness publishes isn't implemented.

If you want to import an instance into a test/dry-run state (in the cluster, to test an import; in the general case, to do something like test new hardware or configuration), you currently risk spamming users with a lot of duplicate notifications. In particular, if Phabricator tracks remotes, both instances will continue importing commits and sending email about them. Both instances will try to publish to mirrors, too, which could be bad news, and both instances will try to update linked services.
Instead, provide a flag to let an instance run in "silent mode", which disables all outbound messaging and data.
We need to remember to support this flag on any new outbound channels, but we add about one of those per year so I think that's reasonable.
