Ref T11596. When exporting data from the Phacility cluster, we `bin/files migrate` data from S3 into a database dump on the `aux` tier.
With current semantics, this //moves// the data and destroys it in S3.
Add a `--copy` flag to //copy// the data instead. This leaves the old copy around, which is what we want for exports.
Test Plan:
- Ran `bin/files migrate` to go from `blob` to `disk` with `--copy`. Verified a copy was left in the database.
- Copied it back, verified a copy was left on disk (total: 2 database copies, 1 disk copy).
- Moved it back without copy, verified database was destroyed and disk was created (total: 1 database copy, 2 disk copies).

Fixes T11242. See that task for detailed discussion.
Previously, it didn't particularly matter that we don't MIME detect chunked files since they were all just big blobs of junk (PSDs, zips/tarballs, whatever) that we handled uniformly.
However, videos are large and the MIME type also matters.
- Detect the overall mime type by detecitng the MIME type of the first chunk. This appears to work properly, at least for video.
- Skip mime type detection on other chunks, which we were performing and ignoring. This makes uploading chunked files a little faster since we don't need to write stuff to disk.
Test Plan:
Uploaded a 50MB video locally, saw it as chunks with a "video/mp4" mime type, played it in the browser in Phabricator as an embedded HTML 5 video.

- Provide a new configuation option, `keyring`, for specifying encryption keys.
- One key may be marked as `default`. This activates AES256 encryption for Files.
- Add `bin/files generate-key`. This is helps when generating valid encryption keys.
- Add `bin/files encode`. This changes the storage encoding of a file, and helps test encodings and migrate existing data.

Summary:
Ref T11140. This doesn't do anything yet since there's no way to enable it and no way to store master keys.
Those are slightly tougher problems and I'm not totally satisfied that I have an approach I really like for either problem, so I may wait for a bit before tackling them. Once they're solved, this does the mechanical encrypt/decrypt stuff, though.
This design is substantially similar to the AWS S3 server-side encryption design, and intended as an analog for it. The decisions AWS has made in design generally seem reasonable to me.
Each block of file data is encrypted with a unique key and a unique IV, and then that key and IV are encrypted with the master key (and a distinct, unique IV). This is better than just encrypting with the master key directly because:
- You can rotate the master key later and only need to re-encrypt a small amount of key data (about 48 bytes per file chunk), instead of re-encrypting all of the actual file data (up to 4MB per file chunk).
- Instead of putting the master key on every server, you can put it on some dedicated keyserver which accepts encrypted keys, decrypts them, and returns plaintext keys, and can send it 32-byte keys for decryption instead of 4MB blocks of file data.
- You have to compromise the master key, the database, AND the file store to get the file data. This is probably not much of a barrier realistically, but it does make attacks very slightly harder.
The "KeyRing" thing may change once I figure out how I want users to store master keys, but it was the simplest approach to get the unit tests working.
Test Plan:
- Ran unit tests.
- Dumped raw data, saw encrypted blob.
- No way to actually use this in the real application yet so it can't be tested too extensively.

This either generates the preview or redirects to an existing preview. This is a good behavior in general, because the preview may take a while to generate and we don't want to wait for it to generate on the server side.
However, this flickers a lot in Safari. We might be able to cache this, but we really shouldn't, since the preview URI isn't a legitimately stable/permanent one.
Instead, do a (cheap) server-side check to see if the preview already exists. If it does, return a direct URI. This gives us a stable thumbnail in Safari.

The URI will stop working once any attached object changes its view policy, or the file view policy itself changes.
Files with `canCDN` (totally public data like profile images, CSS, JS, etc) use "cache-control: public" so they can be CDN'd.
Files without `canCDN` use "cache-control: private" so they won't be cached by the CDN. They could still be cached by a misbehaving local cache, but if you don't want your users seeing one anothers' secret files you should configure your local network properly.
Our "Cache-Control" headers were also from 1999 or something, update them to be more modern/sane. I can't find any evidence that any browser has done the wrong thing with this simpler ruleset in the last ~10 years.

The new workflow goes like this:
> Client, file.allocate(): I'd like to upload a file with length L, metadata M, and hash H.
Then the server returns `upload` (a boolean) and `filePHID` (a PHID). These mean:
| upload | filePHID | means |
|---|---|---|
| false | false | Server can't accept file.
| false | true | File data already known, file created from hash.
| true | false | Just upload normally.
| true | true | Query chunks to start or resume a chunked upload.
All but the last case are uninteresting and work like exising uploads with `file.uploadhash` (which we can eventually deprecate).
In the last case:
> Client, file.querychunks(): Give me a list of chunks that I should upload.
This returns all the chunks for the file. Chunks have a start byte, an end byte, and a "complete" flag to indicate that the server already has the data.
Then, the client fills in chunks by sending them:
> Client, file.uploadchunk(): Here is the data for one chunk.
This stuff doesn't work yet or has some caveats:
- I haven't tested resume much.
- Files need an "isPartial()" flag for partial uploads, and the UI needs to respect it.
- The JS client needs to become chunk-aware.
- Chunk size is set crazy low to make testing easier.
- Some debugging flags that I'll remove soon-ish.
- Downloading works, but still streams the whole file into memory.
- This storage engine is disabled by default (hardcoded as a unit test engine) because it's still sketchy.
- Need some code to remove the "isParital" flag when the last chunk is uploaded.
- Maybe do checksumming on chunks.
Test Plan:
- Hacked up `arc upload` (see next diff) to be chunk-aware and uploaded a readme in 18 32-byte chunks. Then downloaded it. Got the same file back that I uploaded.
- File UI now shows some basic chunk info for chunked files:

Summary:
Fixes T5843. File storage engines use a very old "selector" mechanism which makes them difficult to extend.
This mechanism predates widespread use of `PhutilSymbolLoader` to discover available implementations at runtime. Runtime discovery has generally proven more flexible and easier to use than explicit selection (although it sometimes needs more UI to support it in cases where order or enabled/disabled flags can not be directly determined).
Use a modern runtime discovery mechanism instead of an explicit selector. This might break any installs which subclassed the `Selector`, but I believe almost no such installs exist, and they'll receive a meaningful exception upon upgrading (any custom engines will no longer implement all of the required methods).
Looking forward, this modernizes infrastructure to prepare for new "virtual" chunked-storage engines, with the eventual goal of supporting very large file uploads and data import into the Phacility cluster.
This uses D12051 to add UI to make it easier to understand the state of storage engines.
Test Plan:
Used new UI panel to assess storage engines:
{F336270}
- Uploaded a small file, saw it go to MySQL engine.
- Uploaded a larger file, saw it go to S3 engine.

Summary:
Fixes T7379. Currently, builtin files generate with a "users" view policy even if an install is public.
Because these files TTL after 7 days, there's no migration here. Installs won't see the fix actually happen for up to 7 days after updating, though.
Test Plan:
- Deleted a builtin.
- Loaded projects page to regenerate it.
- Saw new builtin had most open policy and was marked as a builtin.

Summary:
This makes thumbnail URIs work on instanced, CDN'd installs like Phacility cluster instances.
Some of these transforms can proabably be removed, but the underlying code to generate the transform should be cleaned up too and we have some other tasks filed elsewhere about this anyway.
Test Plan: CDN'd local install now loads thumbnails properly.

Summary:
This allows us to CDN the cluster.
General problem is that we can't easily give each instance its own CDN URI (`giraffe.phcdn.net`) in Cloudfront, because it requires that you enumerate all aliases (and there's a limit of 100) and depends on SNI (a newish feature of SSL which allows one server to serve multiple certificates, but which doesn't have full support everywhere yet).
It's //possible// that we could eventually work around this, or use Cloudflare instead (which has a different model that seems like a slightly easier fit for CDN-domain-per-instance), but I don't want to sink a ton of work into this and want to keep things on AWS insofar as we reasonably can.
The easiest way to fix this is just to put the instance identity into URIs, then read it out when handling CDN requests. This has no effect on installs without cluster instance configuration, which is all of them except ours.
It's also slightly desirable to share this stuff, since we get to share the cache for static resources, which are always identical across instances.
So requests go from the Cloudfront gateway ("xyz.cloudfront.com") to the LB with a hard-coded instance name ("cdn.phacility.com"), which gets them routed to a balanced web machine. The web machine picks the correct instance name out of the URI, acts as that instance, and does the correct thing.
The messiest part of this is that we need "cdn.phacility.com" to be a real instance so it can serve static resources, but that's not a big deal. We have a few other hard-codes which have to be real resources for now, like we must have a merchant named "Phacility".
Test Plan:
- Viewed files with `security.alternate-file-domain` off (i.e., no file tokens).
- Viewed pages and files with `security.alternate-file-domain` on. Saw correct resource behavior, @isntance generation of URIs, and correct token redirect behavior for files.
