Summary:
Fixes T13132. I removed this branch in D19156 when tightening the logic for the new CSP header, but there's a legitimate need for it: downloading files via `arc download`, or more generally being an API consumer of files.
This is not completely safe, but attacks I'm aware of (particularly, cookie fixation, where an attacker could potentially force a victim to become logged in to an account they control) are difficult and not very powerful. We already issue clear setup advice about the importance of configuring this option ("Phabricator is currently configured to serve user uploads directly from the same domain as other content. This is a security risk.") and I think there's significant value in letting API clients just GET file data without having to jump through a lot of weird hoops.
Test Plan:
- With `security.alternate-file-domain` off, tried to `arc download` a file.
- Before: downloaded an HTML dialog page.
- After: downloaded the file.

Summary:
Depends on D19251. Ref T13105. This adds rendering engine support for PDFs.
It doesn't actually render them, it just renders a link which you can click to view them in a new window. This is much easier than actually rendering them inline and at least 95% as good most of the time (and probably more-than-100%-as-good some of the time).
This makes PDF a viewable MIME type by default and adds a narrow CSP exception for it. See also T13112.
Test Plan:
- Viewed PDFs in Files, got a link to view them in a new tab.
- Clicked the link in Safari, Chrome, and Firefox; got inline PDFs.
- Verified primary CSP is still `object-src 'none'` with `curl ...`.
- Interacted with the vanilla lightbox element to check that it still works.

Summary:
Depends on D19155. Ref T13094. Ref T4340.
We can't currently implement a strict `form-action 'self'` content security policy because some file downloads rely on a `<form />` which sometimes POSTs to the CDN domain.
Broadly, stop generating these forms. We just redirect instead, and show an interstitial confirm dialog if no CDN domain is configured. This makes the UX for installs with no CDN domain a little worse and the UX for everyone else better.
Then, implement the stricter Content-Security-Policy.
This also removes extra confirm dialogs for downloading Harbormaster build logs and data exports.
Test Plan:
- Went through the plain data export, data export with bulk jobs, ssh key generation, calendar ICS download, Diffusion data, Paste data, Harbormaster log data, and normal file data download workflows with a CDN domain.
- Went through all those workflows again without a CDN domain.
- Grepped for affected symbols (`getCDNURI()`, `getDownloadURI()`).
- Added an evil form to a page, tried to submit it, was rejected.
- Went through the ReCaptcha and Stripe flows again to see if they're submitting any forms.

Depends on D18792. Fixes T13024. Fixes T89198. Currently, when users are logging in initially (for example, need to enter MFA) we show more menu items than we should.
Notably, we may show some personalized/private account details, like the number of unread notifications (probably not relevant) or a user's saved queries (possibly sensitive). At best these are misleading (they won't work yet) and there's an outside possibility they leak a little bit of private data.
Instead, nuke everything except "Log Out" when users have partial sessions.
Test Plan:
Hit a partial session (MFA required, email verification required) and looked at the menu. Only saw "Log Out".

Ref T7567. In T8266 I fixed a bunch of obscure "Range" issues, but only for file downloads -- not for Celerity.
Extend all that stuff to Celerity, which is fortunately much easier.
I believe this will fix Conpherence sounds in Safari.
Test Plan:
- Wrote out an HTTP request in a text file with `Range: bytes=0-1` and similar, piped it to localhost with `cat request.txt | nc localhost 80`, saw server return appropriate range responses consistent with file behavior after T8266, which all seems to work.
- Also did that for files to try to make sure I wasn't breaking anything.

Summary:
Ref T11357. In D17611, I added `file.search`, which includes a `"dataURI"`. Partly, this is building toward resolving T8348.
However, in some cases you can't GET this URI because of a security measure:
- You have not configured `security.alternate-file-domain`.
- The file isn't web-viewable.
- (The request isn't an LFS request.)
The goal of this security mechanism is just to protect against session hijacking, so it's also safe to disable it if the viewer didn't present any credentials (since that means there's nothing to hijack). Add that exception, and reorganize the code a little bit.
Test Plan:
- From the browser (with a session), tried to GET a binary data file. Got redirected.
- Got a download with POST.
- From the CLI (without a session), tried to GET a binary data file. Go a download.

This is largely residual from the days of one-time-tokens, and can cause messy configuration-dependent bugs like the one in T7789#172057.
Instead, always use the omnipotent viewer. Knowledge of the secret key alone is sufficient to access a file.

Ref T10262. This removes one-time tokens and makes file data responses always-cacheable (for 30 days).
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.
Test Plan:
- Configured alternate file domain.
- Viewed site: stuff worked.
- Accessed a file on primary domain, got redirected to alternate domain.
- Verified proper cache headers for `canCDN` (public) and non-`canCDN` (private) files.
- Uploaded a file to a task, edited task policy, verified it scrambled the old URI.
- Reloaded task, new URI generated transparently.

Summary:
Ref T5685. Currently we just 403 on an invalid token, but we can be a little more helpful.
The issues here are:
- If we **do** redirect you on this page and something goes wrong, you might get stuck in a redirect loop.
- If we **don't** redirect you, copy/pasting the link to someone (or reloading the page) gives them a pretty confusing result, since the link doesn't work any more. Prior to this diff, they get a 403.
To mitigate this, do a little better than a bare 403: give them a link to auth and generate a new URI for the file.
If this is still confusing, the next best thing I can come up with is something like this:
- Put some modulous of the timestamp in the URI.
- If the current time is within 2 seconds of the generation time, show this dialog.
- Otherwise, redirect.
That seems like it would be okay, but I worry that "2" has to be small (so links you copy/paste -> chat -> click still work) and a small value means that a small amount of clock skew breaks things. We could use the database clock, but ehhh.
Other ideas:
- Put a hash of the remote IP in the URI, redirect if it doesn't match. Fails for companies behind a NAT gateway but should work in a lot of other cases.
- Just redirect always, there's no reason it should ever loop and browsers don't really do anything bad when there's a loop (they'll show an error after too many redirects).
I'm leaning toward letting this stabilize in the wild for a bit, then trying "always redirect".

Summary:
Fixes T3887. Two issues:
- Macros were generating entirely before the render cache, so audio macros worked fine in previews and the first time the cache was populated, but not afterward.
- Instead, parse them before the cache but drop them in after the cache. Clean up all the file querying, too. This makes cached remarkup generate the correct audio beahviors.
- Safari sends an HTTP request with a "Range" header, and expects a "206 Partial Content" response. If we don't give it one, it sometimes has trouble figuring out how long a piece of audio is (mostly for longer clips? Or mostly for MP3s?). I'm not exactly sure what triggers it. The net effect is that "loop" does not work when Safari gets confused. While looping a short "quack.wav" worked fine, longer MP3s didn't loop.
- Supporting "Range" and "206 Partial Content", which is straightforward, fixes this problem.
Test Plan:
- Viewed a page with lots of different cached audio macros and lots of different uncached preview audio macros, they all rendered correctly and played audio.
- Viewed a macro with a long MP3 audio loop in Safari. Verified it looped after it completed. Used Charles to check that the server received and responded to the "Range" header correctly.

- It confuses Git file copy detection when creating small files.
