Summary:
Ref T6755. In Git and Subversion, running `git clone http://google.com/` or `svn checkout http://google.com/` does not echo the response body.
In Mercurial, it does. Censor it from the output of `hg pull` and `hg clone`. This prevents an attacker from:
- Creating a Mercurial remote repository with URI `http://10.0.0.1/secrets/`; and
- reading the secrets out of the error message after the clone fails.
Test Plan: Set a Mercurial remote URI to a non-Mercurial repository, ran `repository update`, saw censored error message.

Summary:
Ref T6755. Although we do not return response bodies, it is possible to perform crude portscanning if you can execute a DNS rebinding attack (which, for now, remains theoretical).
Limit users to 60 requests / hour to make it less feasible. This would require ~30 years to portscan all ports on a `/32` netblock.
Users who can guess that services may exist can confirm their existence more quickly than this, but if the attacker already had a very small set of candidate services it seems unlikely that portscanning would be of much use in executing the attack.
This protection should eventually be applied to T4190, too (that task also has other considerations).
Test Plan: Set rate limit very low, hit rate limit.

Summary:
Fixes T7664. When there are a large number of tasks (400+) with the same subpriority (which can happen if the subpriority features are rarely used), it may take more than 30 seconds to rebalance them.
Make the algorithm more aggressive about rebalancing homogenous blocks of tasks.
This may need to get even fancier, but I'd guess it can process blocks 1-2 orders of magnitude larger, which should be ~all installs.
(If someone still hits issues with this, I'll make it fancier.)
Once a block is rebalanced, it doesn't need to be rebalanced again (at least, not as a whole block) so we basically just need to get over the initial hurdle here and then we're good.
In the worst case, we can provide `bin/maniphest rebalance` or similar and do the rebalance step offline.
And, in any case, we have more test coverage here now.

- Existing tests.

Summary:
Ref T6755. This mitigates an attack where you:
- compromise an administrative account;
- configure "text/plain" as an "image" MIME type; and
- create a new macro sourced from a sensitive resource which is locally accessible over HTTP GET, using DNS rebinding.
You can then view the content of the resource in Files. By preventing the compromised account from reconfiguring the MIME types, the server will instead destroy the response and prevent the attacker from seeing it.
In general, these options should change very rarely, and they often sit just beyond the edge of security vulnerabilities anyway.
For example, if you ignore the warnings about an alternate file domain and elect to serve content from the primary domain, it's still somewhat difficult for an attacker to exploit the vulnerability. If they can add "text/html" or "image/svg+xml" as image MIME types, it becomes trivial. In this case not having an alternate domain is the main issue, but easy modification of this config increases risk/exposure.

...where "Trivial Line B" is something like a curly brace. If you move this block somewhere that happened to previously have a similar trivial curly brace line, we won't be able to find 3 contiguous added lines in order to detect the copy/move.
Instead, consider both changed and unchanged lines when trying to find contiguous blocks. This allows us to detect across gaps where lines were not actually changed.
This new algorithm may be too liberal (for example, we may end up incorrectly identifying moved/copied code before or after changed lines, not just between changed lines), but we can keep an eye on it and tweak it. The algorithm is better factored and better covered, now.

Summary:
Ref T5644. See some discussion in D8040.
When a file is very large (more than 64KB of text), don't activate syntax highlighting by default. This should prevent us from wasting resources running `pygmentize` on enormous files.
Users who want the file highlighted can still select "Highlight As...".
The tricky part of this diff is separating the headers into "changeset" headers and "undershield" (rendering) headers. Specifically, a file might have these headers/shields:
- "This file is newly added."
- "This file is generated. Show Changes"
- "Highlighting is disabled for this large file."
In this case, I want the user to see "added" and "generated" when they load the page, and only see "highlighting disabled" after they click "Show Changes". So there are several categories:
- "Changeset" headers, which discuss the changeset as a whole (binary file, image file, moved, added, deleted, etc.)
- "Property" headers, which describe metadata changes (not relevant here).
- "Shields", which hide files from view by default.
- "Undershield" headers, which provide rendering information that is only relevant if there is no shield on the file.
Test Plan:
- Viewed a diff with the library map, clicked "show changes", got a "highlighting disabled" header back with highlighting disabled.
- Enabled highlighting explicitly (this currently restores the shield, which it probably shouldn't, but that feels out of scope for this change). The deshielded file is highlighted per the user's request.
- Loaded context on normal files.

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.

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.

Summary:
Ref T7149. When users give us dumpfiles for import, they will almost inevitably use the `phabricator` namespace. They need to be renamed to use an instance namespace.
We can do this either by:
- importing the data first, then renaming; or
- renaming first, then importing.
This implements the second one, basically `storage renamespace --in dump.sql --from phabricator --to instancename > instance.sql`.
Renaming first is a little hackier since we have to `preg_match()` a SQL dump file, but I think it's better overall:
- With only one database, it lets you dump/import without downtime.
- If you have development stuff in a development environment in the `phabricator` namespace, you don't have to move it aside to do an import.
- No possibility that two people doing an import at the same time on the same box will collide with each other.
- You can do the rename once and then repeat the import process with the renamed dump more easily.
- No tricky stuff with modern Phabricator running against an old dump and the database names not matching up.
None of this is super important, but it just makes large dumps a bit easier to work with, and the dumpfile format is regular enough that this seems unlikely to ever really not work.
Test Plan: Renamespaced a dump, did a `diff -u`, saw all the relevant parts changed (and only those parts changed).
