Ref T7477. This option was added in D842 in 2011, to support a specific narrow use case at Quora with community moderators using some kind of weird Gmail config.
I don't recall it ever coming up since then, and a survey of a subset of hosted instances (see T11760) reveals that no instances are using this option today. Presumably, even Quora has completed the onboarding discussed in D842, if they still use Phabricator. This option generally does not seem very useful outside of very unusual/narrow cases like the one Quora had.
This would be relatively easy to restore as a local patch if installs //do// need it, but I suspect this has no use cases anywhere.

I think no plausible receiver can ever do anything useful with this kind of mail, so we can safely drop it earlier and simplify some of the logic. After T7477, we'd end up throwing multiple exceptions if you sent empty mail to several valid receivers.
(I also want to move away from APIs oriented around raw addresses in more specialized layers, and this is one of the few callsites for raw mail address information.)
This requires updating some unit tests to actually have message bodies, since they failed with this error before hitting the other errors otherwise.

Ref T12509.
- Remove the "phabricator.csrf-key" configuration option in favor of automatically generating an HMAC key.
- Upgrade two hasher callsites (one in CSRF itself, one in providing a CSRF secret for logged-out users) to SHA256.
- Extract the CSRF logic from `PhabricatorUser` to a standalone engine.
I was originally going to do this as two changes (extract logic, then upgrade hashes) but the logic had a couple of very silly pieces to it that made faithful extraction a little silly.
For example, it computed `time_block = (epoch + (offset * cycle_frequency)) / cycle_frequency` instead of `time_block = (epoch / cycle_frequency) + offset`. These are equivalent but the former was kind of silly.
It also computed `substr(hmac(substr(hmac(secret)).salt))` instead of `substr(hmac(secret.salt))`. These have the same overall effect but the former is, again, kind of silly (and a little bit materially worse, in this case).
This will cause a one-time compatibility break: pages loaded before the upgrade won't be able to submit contained forms after the upgrade, unless they're open for long enough for the Javascript to refresh the CSRF token (an hour, I think?). I'll note this in the changelog.
Test Plan:
- As a logged-in user, submitted forms normally (worked).
- As a logged-in user, submitted forms with a bad CSRF value (error, as expected).
- As a logged-out user, hit the success and error cases.

Ref T920. This simplifies mail configuration.
The "metamta.domain" option is only used to generate Thread-ID values, and we just need something that looks like a bit like a domain in order to make GMail happy. Just use the install domain. In most cases, this is almost certainly the configured value anyway. In some cases, this may cause a one-time threading break for existing threads; I'll call this out in the changelog.
The "metamta.placeholder-to-recipient" is used to put some null value in "To:" when a mail only has CCs. This is so that if you write a local client mail rule like "when I'm in CC, burn the message in a fire" it works even if all the "to" addresses have elected not to receive the mail. Instead: just send it to an unlikely address at our own domain.
I'll add some additional handling for the possiblity that we may receive this email ourselves in the next change, but it overlaps with T7477.

Ref T12509. This upgrades a `weakDigest()` callsite to SHA256-HMAC and removes three config options:
- `celerity.resource-hash`: Now hard-coded, since the use case for ever adjusting it was very weak.
- `celerity.enable-deflate`: Intended to make cache inspection easier, but we haven't needed to inspect caches in ~forever.
- `celerity.minify`: Intended to make debugging minification easier, but we haven't needed to debug this in ~forever.
In the latter two cases, the options were purely developer-focused, and it's easy to go add an `&& false` somewhere in the code if we need to disable these features to debug something, but the relevant parts of the code basically work properly and never need debugging. These options were excessively paranoid, based on the static resource enviroment at Facebook being far more perilous.
The first case theoretically had end-user utility for fixing stuck content caches. In modern Phabricator, it's not intuitive that you'd go adjust a Config option to fix this. I don't recall any users ever actually running into problems here, though.
(An earlier version of this change did more magic with `celerity.resource-hash`, but this ended up with a more substantial simplification.)

Ref T13222. In D19918, I refactored how timelines get "view data". Today, this is always additional data about which images/changesets/diffs are visible on the current revision/commit/mock, so we can tell if inline comments should be linked to a `#anchor` on the same page (if the inline is rendered there somewhere) or to a `/D123?id=1&vs=2` full link on a different page (if it isn't), but in general this could be any sort of state information about the current page that affects how the timeline should render.
Previously, comment previews did not use any specialized object code and always rendered a "generic" timeline story. This was actually a bug, but none of the code we have today cares about this (since it's all inline related, and inlines render separately) so it never impacted anything.
After the `TimelineEngine` change, the preview renders with Differential-specific code. This is more correct, but we were not passing the preview the "view data" so it broke.
This preview doesn't actually need the view data and we could just make it bail out if it isn't present, but pass it through for consistency and so this works like we'd expect if we do something fancier with view data in the future.

This behavior is convenient for full sessions, but normal users don't ever spend 30 minutes answering MFA, so there's no real reason to do it for partial sessions. If we add login alerts in the future, limiting partial sessions to a short lifetime will make them more useful, since an attacker can't get one partial session and keep extending it forever while waiting for an opportunity to get past your MFA.

Instead, allow `bin/auth recover` to generate a link that skips the "partial session" stage: adding required MFA, providing MFA, and signing legalpad documents.
Anyone who can run `bin/auth recover` can do this anyway, this just reduces the chance I accidentally bypass MFA on the wrong session when doing support stuff.

The goal at the time was to let Harbormaster post build results to Diffs and have them end up on Revisions, but this eventually got a better implementation (see below) where the Harbormaster-specific code can just specify a "publishable object" where build results should go.
The new `get...Object` semantics ultimately broke some stuff, and the actual implementation in Differential was removed in D10911, so this method hasn't really served a purpose since December 2014. I think that broke the Harbormaster thing by accident and we just lived with it for a bit, then Harbormaster got some more work and D17139 introduced "publishable" objects which was a better approach. This was later refined by D19281.
So: the original problem (sending build results to the right place) has a good solution now, this method hasn't done anything for 4 years, and it was probably a bad idea in the first place since it's pretty weird/surprising/fragile.
Note that `Comment` objects still have an unrelated method with the same name. In that case, the method ties the `Comment` storage object to the related `Transaction` storage object.
Test Plan: Grepped for `getApplicationTransactionObject`, verified that all remaining callsites are related to `Comment` objects.

Depends on D19918. Ref T11351. In D19918, I removed all calls to this method. Now, remove all implementations.
All of these implementations just `return $timeline`, only the three sites in D19918 did anything interesting.
Test Plan: Used `grep willRenderTimeline` to find callsites, found none.

Summary:
Depends on D19914. Ref T11351. Some of the Phoilo rabbit holes go very deep.
`PhabricatorApplicationTransactionInterface` currently requires you to implement `willRenderTimeline()`. Almost every object just implements this as `return $timeline`; only Pholio, Diffusion, and Differential specialize it. In all cases, they are specializing it mostly to render inline comments.
The actual implementations are a bit of a weird mess and the way the data is threaded through the call stack is weird and not very modern.
Try to clean this up:
- Stop requiring `willRenderTimeline()` to be implemented.
- Stop requiring `getApplicationTransactionViewObject()` to be implemented (only the three above, plus Legalpad, implement this, and Legalpad's implementation is a no-op). These two methods are inherently pretty coupled for almost any reasonable thing you might want to do with the timeline.
- Simplify the handling of "renderdata" and call it "View Data". This is additional information about the current view of the transaction timeline that is required to render it correctly. This is only used in Differential, to decide if we can link an inline comment to an anchor on the same page or should link it to another page. We could perhaps do this on the client instead, but having this data doesn't seem inherently bad to me.
- If objects want to customize timeline rendering, they now implement `PhabricatorTimelineInterface` and provide a `TimelineEngine` which gets a nice formal stack.
This leaves a lot of empty `willRenderTimeline()` implementations hanging around. I'll remove these in the next change, it's just going to be deleting a couple dozen copies of an identical empty method implementation.
Test Plan:
- Viewed audits, revisions, and mocks with inline comments.
- Used "Show Older" to page a revision back in history (this is relevant for "View Data").
- Grepped for symbols: willRenderTimeline, getApplicationTransactionViewObject, Legalpad classes.

Summary:
Ref T11351. In Pholio, we currently use a `mockID`, but a `mockPHID` is generally preferable / more modern / more flexible. In particular, we need PHIDs to load handles and prefer PHIDs when exposing information to the API, and using PHIDs internally makes a bunch of things easier/better/faster and ~nothing harder/worse/slower.
I'll add some inlines about a few things.
Test Plan: Ran migrations, spot-checked database for sanity. Loaded Pholio, saw data unchanged. Created and edited images.

Summary: Depends on D19895. Ref T13222. This is a simple behavioral improvement for the current MFA implementation in Legalpad: don't MFA the user and //then// realize that they forgot to actually check the box.
Test Plan:
- Submitted form without the box checked, got an error saying "check the box" instead of MFA.
- Submitted the form with the box checked, got an MFA prompt.
- Passed the MFA gate, got a signed form.
- Tried to sign another form, hit MFA timed lockout.

Summary:
Depends on D19894. Ref T13222. See PHI873. When you provide a correct response to an MFA challenge, we mark it as "answered".
Currently, we never let you reuse an "answered" token. That's usually fine, but if you have 2+ factors on your account and get one or more (but fewer than all of them) right when you submit the form, you need to answer them all again, possibly after waiting for a lockout period. This is needless.
When you answer a challenge correctly, add a hidden input with a code proving you got it right so you don't need to provide another answer for a little while.
Why not just put your response in a form input, e.g. `<input type="hidden" name="totp-response" value="123456" />`?
- We may allow the "answered" response to be valid for a different amount of time than the actual answer. For TOTP, we currently allow a response to remain valid for 60 seconds, but the actual code you entered might expire sooner.
- In some cases, there's no response we can provide (with push + approve MFA, you don't enter a code, you just tap "yes, allow this" on your phone). Conceivably, we may not be able to re-verify a push+approve code if the remote implements one-shot answers.
- The "responseToken" stuff may end up embedded in normal forms in some cases in the future, and this approach just generally reduces the amount of plaintext MFA we have floating around.
Test Plan:
- Added 2 MFA tokens to my account.
- Hit the MFA prompt.
- Provided one good response and one bad response.
- Submitted the form.
- Old behavior: good response gets locked out for ~120 seconds.
- New behavior: good response is marked "answered", fixing the other response lets me submit the form.

Summary:
Depends on D19893. Ref T13222. See PHI873. A challenge is "answered" if you provide a valid response. A challenge is "completed" if we let you through the MFA check and do whatever actual action the check is protecting.
If you only have one MFA factor, challenges will be "completed" immediately after they are "answered". However, if you have two or more factors, it's possible to "answer" one or more prompts, but fewer than all of the prompts, and end up with "answered" challenges that are not "completed".
In the future, it may also be possible to answer all the challenges but then have an error occur before they are marked "completed" (for example, a unique key collision in the transaction code). For now, nothing interesting happens between "answered" and "completed". This would take the form of the caller explicitly providing flags like "wait to mark the challenges as completed until I do something" and "okay, mark the challenges as completed now".
This change prevents all token reuse, even on the same workflow. Future changes will let the answered challenges "stick" to the client form so you don't have to re-answer challenges for a short period of time if you hit a unique key collision.
Test Plan:
- Used a token to get through an MFA gate.
- Tried to go through another gate, was told to wait for a long time for the next challenge window.

Summary:
Depends on D19890. Ref T13222. See PHI873. Currently, we only validate TOTP responses against the current (realtime) timestep. Instead, also validate them against a specific challenge.
This mostly just moves us toward more specifically preventing responses from being reused, and supporting flows which must look more like this (SMS/push).
One rough edge here is that during the T+3 and T+4 windows (you request a prompt, then wait 60-120 seconds to respond) only past responses actually work (the current code on your device won't). For example:
- At T+0, you request MFA. We issue a T+0 challenge that accepts codes T-2, T-1, T+0, T+1, and T+2. The challenge locks out T+3 and T+4 to prevent the window from overlapping with the next challenge we may issue (see D19890).
- If you wait 60 seconds until T+3 to actually submit a code, the realtime valid responses are T+1, T+2, T+3, T+4, T+5. The challenge valid responses are T-2, T-1, T+0, T+1, and T+2. Only T+1 and T+2 are in the intersection. Your device is showing T+3 if the clock is right, so if you type in what's shown on your device it won't be accepted.
- This //may// get refined in future changes, but, in the worst case, it's probably fine if it doesn't. Beyond 120s you'll get a new challenge and a full [-2, ..., +2] window to respond, so this lockout is temporary even if you manage to hit it.
- If this //doesn't// get refined, I'll change the UI to say "This factor recently issued a challenge which has expired, wait N seconds." to smooth this over a bit.
Test Plan:
- Went through MFA.
- Added a new TOTP factor.
- Hit some error cases on purpose.
- Tried to use an old code a moment after it expired, got rejected.
- Waited 60+ seconds, tried to use the current displayed factor, got rejected (this isn't great, but currently expected).

Summary:
Depends on D19889. Ref T13222. Some of this logic is either not-quite-right or a little more complicated than it needs to be.
Currently, we TTL TOTP challenges after three timesteps -- once the current code could no longer be used. But we actually have to TTL it after five timesteps -- once the most-future acceptable code could no longer be used. Otherwise, you can enter the most-future code now (perhaps the attacker compromises NTP and skews the server clock back by 75 seconds) and then an attacker can re-use it in three timesteps.
Generally, simplify things a bit and trust TTLs more. This also makes the "wait" dialog friendlier since we can give users an exact number of seconds.
The overall behavior here is still a little odd because we don't actually require you to respond to the challenge you were issued (right now, we check that the response is valid whenever you submit it, not that it's a valid response to the challenge we issued), but that will change in a future diff. This is just moving us generally in the right direction, and doesn't yet lock everything down properly.
Test Plan:
- Added a little snippet to the control caption to list all the valid codes to make this easier:
```
$key = new PhutilOpaqueEnvelope($config->getFactorSecret());
$valid = array();
foreach ($this->getAllowedTimesteps() as $step) {
$valid[] = self::getTOTPCode($key, $step);
}
$control->setCaption(
pht(
'Valid Codes: '.implode(', ', $valid)));
```
- Used the most-future code to sign `L3`.
- Verified that `L4` did not unlock until the code for `L3` left the activation window.
