Summary:
I wanted to point someone on a file uploaded to Phabricator and the normal link is just too long.
I guess that this also improves security. Because pointing someone to the file directly reveals the secret key used in /data/ and it can be served without auth?
We already use `{F123}` so there will be no conflicts in future because we wouldn't want to reuse it for something else.
I promote the link on /file/ - it adds one redirect but I think it's worth it. I also considered making the link from the File ID column but there are already too many links (with some duplicity).

Summary:
We don't use versioned URIs for images, so when they change users may get old versions.
This was a particular issue with the recent logo change, which several users reported cache-related issues from.
Instead, use Celerity to manage image URI versions in addition to CSS/JS.
This is complicated, because we need to rewrite image URIs inside of CSS, which means the hash of a CSS file has to be derived from the current image data. Otherwise, when we updated an image the CSS wouldn't update, so we wouldn't be any better off.
So basically we:
- Find all the "raw" files, and put them into the map.
- Find all the CSS/JS, perform content-altering transformations on it (i.e., not minification) based on the partial map, and then put it into the map based on transformed hashes.
(If we wanted, we could now do CSS variables or whatever for "free", more or less.)
Test Plan:
- Regenerated celerity map, browsed site, verified images generated with versioned URIs.
- Moved "blue" flag image over "green" flag image, regenerated map, verified "green" flag image and the associated CSS changed hashes.
- Added transformation unit tests; ran unit tests.

- Use Files to serve raw data so we get all the security benefits of the alternate file domain. Although the difficulty of exploiting this is high (you need commit access to the repo) there's no reason to leave it dangling.
- Add a "contentHash" to Files so we can lookup files by content rather than adding some weird linker table. We can do other things with this later, potentially.
- Don't use 'data' URIs since they're crazy and we can just link to the file URI.
- When showing a binary file or an image, don't give options like "show highlighted text with blame" or "edit in external editor" since they don't make any sense.
- Use the existing infrastructure to figure out if things are images or binaries instead of an ad-hoc thing in this class.

"Content-Disposition: attachment"
Summary:
We currently serve some files off the primary domain (with "Content-Disposition:
attachment" + a CSRF check) and some files off the alternate domain (without
either).
This is not sufficient, because some UAs (like the iPad) ignore
"Content-Disposition: attachment". So there's an attack that goes like this:
- Alice uploads xss.html
- Alice says to Bob "hey download this file on your iPad"
- Bob clicks "Download" on Phabricator on his iPad, gets XSS'd.
NOTE: This removes the CSRF check for downloading files. The check is nice to
have but only raises the barrier to entry slightly. Between iPad / sniffing /
flash bytecode attacks, single-domain installs are simply insecure. We could
restore the check at some point in conjunction with a derived authentication
cookie (i.e., a mini-session-token which is only useful for downloading files),
but that's a lot of complexity to drop all at once.
(Because files are now authenticated only by knowing the PHID and secret key,
this also fixes the "no profile pictures in public feed while logged out"
issue.)

See T549. Under configurations where files are served from an alternate domain
which does not have cookie credentials, we use random keys to prevent browsing,
similar to how Facebook relies on pseudorandom information in image URIs (we
could some day go farther than this and generate file sessions on the alternate
domain or something, I guess).
Currently, we generate these random keys in a roundabout manner. Instead, use a
real entropy source and store the key on the object. This reduces the number of
sha1() calls in the codebase as per T547.

Configured alternate file domain, uploaded file, verified secret generated and

- Never allow writes without CSRF checks.

We don't currently validate CSRF tokens on this workflow. This allows an
attacker to upload arbitrary files on the user's behalf. Although I believe the
tight list of servable mime-types means that's more or less the end of the
attack, this is still a vulnerability.
In the long term, the right solution is probably to pass CSRF tokens on all Ajax
requests in an HTTP header (or just a GET param) or something like that.
However, this endpoint is unique and this is the quickest and most direct way to
close the hole.
