Summary:
Currently, custom Sites must match `.*` or similar to handle 404's, since the fallback is always generic.
This locks them out of the "redirect to canonicalize to `path/` code", so they currently have a choice between a custom 404 page or automatic correction of `/`.
Instead, allow the 404 controller to be constructed explicitly. Sites can now customize 404 by implementing this method and not matching everything.
(Sites can still match everything with a catchall rule if they don't want this behavior for some reason, so this should be strictly more powerful than the old behavior.)
See next diff for CORGI.
Test Plan:
- Visited real 404 (like "/asdfafewfq"), missing-slash-404 (like "/maniphest") and real page (like "/maniphest/") URIs on blog, main, and CORGI sites.

Ref T11922. After updating to HEAD of `master`, you need to manually rebuild the index. We don't do this during `bin/storage upgrade` because it can take a very long time (`secure.phabricator.com` took roughly an hour) and can happen while Phabricator is running.
However, if we don't warn users about this they'll just get a broken index unless they go read the changelog (or file an issue, then we tell them to go read the changelog).
This adds a very simple table for notes to administrators so we can write a "you need to go rebuild the index" note, then adds one.
Administrators clear the note by completing the activity and running `bin/config done reindex`. This isn't automatic because there are various strategies you can use to approach the issue, which I'll discuss in greater detail in the linked documentation.
Also, fix an issue where `bin/storage upgrade --apply <patch>` could try to re-mark an already-applied patch as applied.

- Ran storage ugrades.
- Got instructions to rebuild search index.

Summary:
Ref T6740. Currently, we issue fulltext queries with an "ORDER BY <score>" on the entire result set.
For very large result sets, this can require MySQL to do a lot of work. However, this work is generally useless: if you search for some common word like "diff" or "internet" or whatever and match 4,000 documents, the chance that we can score whatever thing you were thinking of at the top of the result set is nearly nothing. It's more useful to return quickly, and let the user see that they need to narrow their query to get useful results.
Instead of doing all that work, let MySQL find up to 1,000 results, then pick the best ones out of those.
This actual change is a little flimsy, since our index isn't really big enough to suffer indexing issues. However, searching for common terms on my local install (where I have some large repositories imported and indexed) drops from ~40ms to ~10ms.
My hope is to improve downstream performance for queries like "translatewiki" here, particularly:
<https://phabricator.wikimedia.org/T143863>
That query matches about 300 trillion documents but there's a ~0% chance that the one the user wants is at the top. It takes a couple of seconds to execute, for me. Better to return quickly and let the user refine their results.
I think this will also make some other changes related to stemming easier.
This also removes the "list users first" ordering on the query, which made performance more complicated and seems irrelevant now that we have the typeahead.
Test Plan:
- Searched for some common terms like "code" locally, saw similar results with better performance.
- Searched for useful queries (e.g., small result set), got identical results.

This is fairly rare, but not unheard of. More commonly, we can have this sequence:
- `03.newtable.sql`: Add a new column to Phame.
- `04.setvalue.php`: Copy data into that new column.
In both cases, when applying database-by-database, we can get into trouble.
- In the first case, if Files is on a different master, we'll try to move data into a new table before creating the table.
- In the second case, if Phame is on a different master, the PHP patch will connect to it before we add the new column.
In either case, we try to interact with tables or columns which don't exist yet.
Instead, apply each patch in order, to all databases which need it. So we'll apply `01.newtable.sql` EVERYWHERE first, then move on.
In the case of PHP patches, we also now only apply them once, since they never make schema changes. It should normally be OK to apply them more than once safely, but this is a little faster and a little safer if we ever make a mistake.

Introducing an element of chaotic unpredictability into operations trains staff to be on high alert at all times, rather than lulled into complacency by predictability or consistency.
When Puppet reverts a Phabricator host's configuration to an older version, we might start writing data to a lot of crazy places where it shouldn't go. This will create a big sticky mess that is virtually impossible to undo, mostly because we'll get two files with ID 123 or two tasks with ID 456 or whatever else and good luck with that.
Instead, after changing the partition layout, require `bin/storage partition` to be run. This writes a copy of the config everywhere.
Then, when we start serving web requests, make sure every database has the exact same config. This will foil Puppet by refusing to run requests on hosts it has reverted.

Ref T10759. We may "discover" the presence of a fatal setup error later, after starting Phabricator.
This can happen in a few ways, but most are unlikely. The one I'm immediately concerned about is:
- Phabricator starts up during a disaster with some databases unreachable.
- We start with warnings (unreachable databases are generally not fatal, since it's OK for some subset of hosts to be down in replicated/partitioned setups).
- The unreachable databases later recover and become accessible again.
- When we run checks against them, we discover that they are misconfigured.
Currently, "fatal" setup issues are not truly fatal if we're "in flight" -- we've survived setup checks at least once in the past. This is bad in the scenario above.
Especially with partitioning, it could lead to mangled data in a disaster scenario where operations staff makes a small configuration mistake while trying to get things running again.
Instead, if we "discover" a fatal error while already "in flight", reset the whole setup process as though the webserver had just restarted. Don't serve requests again until we can make it through setup without hitting fatals.
Test Plan:
- Started Phabricator with multiple masters, one of which was down and broken.
- Got a warning about the bad master.
- Revived the master.

These checks also sort of cheat through restart during a recovery, when some hosts will be unreachable: they test for "disaster" by seeing if no masters are reachable, and just skip all the checks in that case.
This is bad for at least two reasons:
- After recent changes, it is possible that //some// masters are dead but it's still OK to start. For example, "slowvote" may have no master, but everything else is reachable. We can safely run without slowvote.
- It's possible to start during a disaster and miss important setup checks completely, since we skip them, get a clean bill of health, and never re-test them.
Instead:
- Test each host individually.
- Fundamental problems (lack of InnoDB, bad schema) are fatal on any host.
- If we can't connect, raise it as a //warning// to make sure we check it later. If you start during a disaster, we still want to make sure that schemata are up to date if you later recover a host.
In particular, I'm going to add these checks soon:
- Fatal if a "master" is replicating.
- Fatal if a "replica" is not replicating.
- Fatal if a database partition config differs from web partition config.
- When we let a database off with a warning because it's down, and later upgrade it to a fatal because we discover it is broken after it comes up again, fatal everything. Currently, we keep running if we "discover" the presence of new fatals after surviving setup checks for the first time.

Test Plan:
- Tried to name something "quack.git", was politely rejected.
- Named something "quack.notgit", and it worked fine.
- Cloned Mercurial and Git repositories over SSH with ".git" and non-".git" variants without hitting any issues.

Maniphest Tasks: T11902
Differential Revision: https://secure.phabricator.com/D16908
Summary:
Ref T11044. I'm going to hold this until after the release cut, but I think it's good to go.
This allows installs to configure multiple masters in `cluster.databases` and partition applications across them (for example, put Maniphest on a dedicated database).
When we make a Maniphest connection we go look up which master we should be hitting first, then connect to it.
This has at least approximately been planned for many years, so the actual change is largely just making sure that your config makes sense.
Test Plan:
- Configured `db001.epriestley.com` and `db002.epriestley.com` as master/master.
- Partitioned applications between them.
- Interacted with various applications, saw writes go to the correct host.
- Viewed "Database Servers" and saw partitioning information.
- Ran schema upgrades.
