Ideally, we would rewrite that migration to not ever have this kind of side effect. However, that would make it much more complicated, and it's already very complicated.
Instead, retroactively expand the size of this field before `storage adjust` does it, so it has the right size by the time we hit the migration in D18037.

Summary:
Ref T12509. This adds support for HMAC+SHA256 (instead of HMAC+SHA1). Although HMAC+SHA1 is not currently broken in any sense, SHA1 has a well-known collision and it's good to look at moving away from HMAC+SHA1.
The new mechanism also automatically generates and stores HMAC keys.
Currently, HMAC keys largely use a per-install constant defined in `security.hmac-key`. In theory this can be changed, but in practice essentially no install changes it.
We generally (in fact, always, I think?) don't use HMAC digests in a way where it matters that this key is well-known, but it's slightly better if this key is unique per class of use cases. Principally, if use cases have unique HMAC keys they are generally less vulnerable to precomputation attacks where an attacker might generate a large number of HMAC hashes of well-known values and use them in a nefarious way. The actual threat here is probably close to nonexistent, but we can harden against it without much extra effort.
Beyond that, this isn't something users should really have to think about or bother configuring.
Test Plan:
- Added unit tests.
- Used `bin/files integrity` to verify, strip, and recompute hashes.
- Tampered with a generated HMAC key, verified it invalidated hashes.

Summary:
The goal is to make fulltext search back-ends more extensible, configurable and robust.
When this is finished it will be possible to have multiple search storage back-ends and
potentially multiple instances of each.
Individual instances can be configured with roles such as 'read', 'write' which control
which hosts will receive writes to the index and which hosts will respond to queries.
These two roles make it possible to have any combination of:
* read-only
* write-only
* read-write
* disabled
This 'roles' mechanism is extensible to add new roles should that be needed in the future.
In addition to supporting multiple elasticsearch and mysql search instances, this refactors
the connection health monitoring infrastructure from PhabricatorDatabaseHealthRecord and
utilizes the same system for monitoring the health of elasticsearch nodes. This will
allow Wikimedia's phabricator to be redundant across data centers (mysql already is,
elasticsearch should be as well).
The real-world use-case I have in mind here is writing to two indexes (two elasticsearch clusters
in different data centers) but reading from only one. Then toggling the 'read' property when
we want to migrate to the other data center (and when we migrate from elasticsearch 2.x to 5.x)
Hopefully this is useful in the upstream as well.
Remaining TODO:
* test cases
* documentation
Test Plan:
(WARNING) This will most likely require the elasticsearch index to be deleted and re-created due to schema changes.
Tested with elasticsearch versions 2.4 and 5.2 using the following config:
```lang=json
"cluster.search": [
{
"type": "elasticsearch",
"hosts": [
{
"host": "localhost",
"roles": { "read": true, "write": true }
}

"protocol": "http",
"path": "/phabricator",
"version": 5
},
{
"type": "mysql",

After this, I can move readers over one at a time and eventually get rid of the old writes and old storage.
This loads all of the edge data into memory in a big chunk. I reached out to one install to get some more information about their data size. Ours is quite manageable and I think even large installs will probably fit into memory, but we can do this in chunks if not.
However, because the Edge table doesn't have an `id` column, we can't use either the `RawMigrationIterator` or the `MigrationIterator`, and would need to write a new `EdgeMigrationIterator`. This isn't tons of work but might not be necessary.

Currently, these are first-class states, partly beacuse we were somewhat limited in what we could do with edges. However, a more flexible way to represent them is as flags separate from the primary state flag.
In the new storage, write them as separate state information: `lastActionDiffPHID` stores the Diff PHID of the last review action (accept, reject, etc). `lastCommentDiffPHID` stores the Diff PHID of the last comment (top-level or inline).

Ref T10967. This is an incremental step toward removing "reviewers" back to a dedicated storage table so we can handle changes like T11050.
This adds the storage table, and starts doing double writes to it (so new or updated reviewers write to both the old edge table and the new "reviewers" table).
Then we can do a migration, swap readers over one at a time, and eventually remove the old write and old storage and then implement new features.
This change has no user-facing impact, it just causes us to write new data to two places instead of one.
This is not completely exhaustive: the Herald "Add Reviewers" action is still doing a manual EDGE transaction. I'll clean that up next and do another pass to look for anything else I missed.
This is also a bit copy/pastey for now but the logic around "RESIGN" is a little different in the two cases until T11050. I'll unify it in future changes.

Summary: Ref T5867, adds a customPHID field, nullable, and lets you query by it... i think? Not fully able to grok all the EditEngine stuff, but I think this is the right place for the query.
Test Plan: Not wired to anything, but pulling up project menu, editing, all still works.
