Summary:
Ref T13222. See PHI873. Currently, when applications prompt users to enter MFA, their session upgrades as a side effect.
In some cases (like managing your email addresses) it makes sense to upgrade your session for a little while since it's common to make multiple edits in sequence (add a new address, make it primary, remove an old address). We generally want MFA to stay out of the way and not feel annoying.
In other cases, we don't expect multiple high-security actions in a row. Notably, PHI873 looks at more "one-shot" use cases where a prompt is answering a specific workflow. We already have at least one of these in the upstream: answering an MFA prompt when signing a Legalpad document.
Introduce a "token" workflow (in contrast to the existing "session") workflow that just does a one-shot prompt without upgrading your session statefully. Then, make Legalpad use this new workflow.
Note that this workflow has a significant problem: if the form submission is invalid for some other reason, we re-prompt you on resubmit. In Legalpad, this workflow looks like:
- Forget to check the "I agree" checkbox.
- Submit the form.
- Get prompted for MFA.
- Answer MFA prompt.
- Get dumped back to the form with an error.
- When you fix the error and submit again, you have to do another MFA check.
This isn't a fatal flaw in Legalpad, but would become a problem with wider adoption. I'll work on fixing this (so the MFA token sticks to the form) in the next set of changes.
Roughly, this is headed toward "MFA sticks to the form/workflow" instead of "MFA sticks to the user/session".
Test Plan:
- Signed a legalpad document with MFA enabled.
- Was prompted for MFA.
- Session no longer upgraded (no purple "session in high security" badge).
- Submitted form with error, answered MFA, fixed error, submitted form again.
- Bad behavior: got re-prompted for MFA. In the future, MFA should stick to the form.

Ref T13216. I want to add some new management options to repositories (e.g., filesize limit, clone timeouts). Before adding new stuff here, update the UI to a full-width, Phortune-style UI.
This partially reverts D18523. About a year ago, several UIs got converted to fixed-width (repository management, config, settings, instance management in SAAS). I didn't think these were good changes and have never really gotten used to them. The rationale wasn't clear to me and these changes just felt like "be more like GitHub". I think usability is significantly worse, e.g. actions are now hidden inside button menus instead of immediately visible.
Phortune also got converted less dramatically to a full-width-with-menu UI, which I like much better. Adjust repository management to use that UI style instead of the fixed-width style.

Ref T13216. Ref T13217. Currently, we build this query in a weird way so we end up with `(1, 2, 3)` on both 32-bit and 64-bit systems.
I can't reproduce the string-vs-int MySQL key issue on any system I have access to, so just simplify this and format as `('1', '2', '3')` instead.
The issue this is working around is that MySQL would (I think?) sometimes appear to do something goofy and miss the key if you formatted the query with strings. I never really nailed this down and could have either been mistaken about it or it could be fixed in all modern versions of MySQL. Until we have better evidence to the contrary, assume MySQL is smart enough to handle this sensibly now.

Add support for limiting the maximum size of any object. Specifically, we:
- list all the objects each commit touches;
- check their size after the commit applies;
- if it's over the limit, reject the commit.
This change doesn't actually hook the limit up (the limit is always "0", i.e. unlimited), and doesn't have Mercurial or SVN support. The actual parser bit would probably be better in some other `Query/Parser` class eventually, too. But it at least roughly works.

Ref T13216. See PHI980. Currently, each application in {nav Applications > X > Configure} has a "Can Configure Application" permission which is hard-coded to "Administrators".
There's no technical reason for this, there just hasn't been a great use case for unlocking it. I think when I originally wrote it our protections against locking yourself out of things weren't that great (i.e., it was easier to set the policy to something that prevented you from editing it after the new policy took effect). Our protections are better now.
The major goal here is to let installs open up Custom Forms for given applications (mostly Maniphest) to more users, but the other options mostly go hand-in-hand with that.
Also, in developer mode, include stack traces for policy exceptions. This makes debugging weird stuff (like the indirect Config application errors here) easier.
Test Plan:
- Granted "Can Configure Application" for Maniphest to all users.
- Edited custom forms as a non-administrator.
- Configured Maniphest as a non-administrator.
- Installed/uninstalled Maniphest as a non-administrator.

Short of that, move toward formalizing a repository "copy time limit": the longest amount of time anything may spend trying to make a copy of this repository.

When a Harbormaster Buildable object is first created for a Diff, it has no `containerPHID` since the revision has not yet been created.
We later (after creating a revision) send the Buildable a message telling it that we've added a container and it should re-link the container object.
Currently, we send this message in `applyExternalEffects()`, which runs inside the Differential transaction. If Harbormaster races quickly enough, it can read the `Diff` object before the transaction commits, and not see the container update.
Add a `didCommitTransaction()` callback after the transactions commit, then move the message code there instead.

- Make order consistent: host, write, read, hook (this is the order the timers start in).
Test Plan: Pushed some stuff, viewed web UI and saw sensible numbers, exported data and got the same values.

Summary:
Ref T13216. See PHI943. If autoscale lightning strikes all your servers at once and destroys them, the path to recovery can be unclear. You're "supposed" to:
- demote all the devices;
- disable the bindings;
- bind the new servers;
- put whatever working copies you can scrape up back on disk;
- promote one of the new servers.
However, the documentation is a bit misleading (it was sort of written with "you lost one or two devices" in mind, not "you lost every device") and demote-before-disable is unnecessary and slightly risky if servers come back online. There's also a missing guardrail before the promote step which lets you accidentally skip the demotion step and end up in a confusing state. Instead:
- Add a guard rail: when you try to promote a new server, warn if inactive devices still have versions and tell the user to demote them.
- Allow demotion of inactive devices: the order "disable, demote" is safer and more intuitive than "demote, disable" and there's no reason to require the unintuitive order.
- Make the "cluster already has leaders" message more clear.
- Make the documentation more clear.
Test Plan:
- Bound a repository to two devices.
- Wrote to A to make it a leader, then disabled it (simulating a lightning strike).
- Tried to promote B. Got a new, useful error ("demote A first").
- Demoted A (before: error about demoting inactive devices; now: works fine).
- Promoted B. This worked.

Summary: Depends on D19796. Simplify some timing code by using phutil_microseconds_since() instead of duplicate casting and arithmetic.
Test Plan: Grepped for `1000000` to find these. Pulled, pushed, made a conduit call. This isn't exhaustive but it should be hard for these to break in a bad way since they're all just diagnostic.

Summary:
Depends on D19779. Ref T13216. The push logs currently record the "hostWait", which is roughly "locking + subprocess cost". We also record locking separately, so we can figure out "subprocess cost" alone by subtracting the lock costs.
However, the subprocess (normally `git receive-pack`) runs hooks, and we don't have an easy way to figure out how much time was spent doing actual `git` stuff vs spent doing commit hook processing. This would have been useful in diagnosing at least one recent issue.
Track at least a rough hook cost and record it in the push logs.
Test Plan: Pushed to a repository, saw a reasonable hook cost appear in the database table.

Summary:
Depends on D19778. Ref T13216. See PHI943, PHI889, et al.
We currently have a push log and a pull log, but do not separately log intracluster synchronization events. We've encountered several specific cases where having this kind of log would be helpful:
- In PHI943, an install was accidentally aborting locks early. Having timing information in the sync log would let us identify this more quickly.
- In PHI889, an install hit an issue with `MaxStartups` configuration in `sshd`. A log would let us identify when this is an issue.
- In PHI889, I floated a "push the linux kernel + fetch timeout" theory. A sync log would let us see sync/fetch timeouts to confirm this being a problem in practice.
- A sync log will help us assess, develop, test, and monitor intracluster routing sync changes (likely those in T13211) in the future.
Some of these events are present in the pull log already, but only if they make it as far as running a `git upload-pack` subprocess (not the case with `MaxStartups` problems) -- and they can't record end-to-end timing.
No UI yet, I'll add that in a future change.
Test Plan:
- Forced all operations to synchronize by adding `|| true` to the version check.
- Pulled, got a sync log in the database.

Summary:
Ref T13216. When a repository is clustered, we run this cleanup code (to tell the repository to update, and log some timing information) on both nodes. Currently, we do slightly too much work, which is unnecessary and can be a bit confusing to human readers.
The double update message doesn't hurt anything, but there's no reason to write it twice.
Likewise, the second timing information update query doesn't do anything: there's no PushEvent object with the right identifier, so it just updates nothing. We don't need to run it, and it's confusing that we do.
Instead, only do these writes if we're actually the final node with the repository on it.
Test Plan: Added some logging, saw double writes/updates before the change and no doubles afterwards, with no other behavioral changes.

See <https://hackerone.com/reports/435648>. We currently use 80-bit TOTP keys. The RFC suggests 128 as a minimum and recommends 160.
The math suggests that doing the hashing for an 80-bit key is hard (slightly beyond the reach of a highly motivated state actor, today) but there's no reason not to use 160 bits instead to put this completely out of reach.
See some additional discussion on the HackerOne report about enormous key sizes, number of required observations, etc.
Test Plan: Added a new 160-bit TOTP factor to Google Authenticator without issue.

Summary:
Ref T13216. We occasionally receive HackerOne reports concerned that you can select your username as a password. I suspect very few users actually do this and that this is mostly a compliance/checklist sort of issue, not a real security issue.
On this install, we have about 41,000 user accounts. Of these, 100 have their username as a password (account or VCS). A substantial subset of these are either explicitly intentional ("demo", "bugmenot") or obvious test accounts ("test" in name, or name is a nonsensical string of gibberish, or looks like "tryphab" or similar) or just a bunch of numbers (?), or clearly a "researcher" doing this on purpose (e.g., name includes "pentest" or "xss" or similar).
So I'm not sure real users are actually very inclined to do this, and we can't really ever stop them from picking awful passwords anyway. But we //can// stop researchers from reporting that this is an issue.
Don't allow users to select passwords which contain words in a blocklist: their username, real name, email addresses, or the install's domain name. These words also aren't allowed to contain the password (that is, neither your password nor your username may be a substring of the other one). We also do a little normalization to try to split apart email addresses, domains, and real names, so I can't have "evan1234" as my password.
Test Plan:
- Added unit tests and made them pass.
- Tried to set my password to a bunch of variations of my username / email / domain name / real name / etc, got rejected.

Ref T13216. See PHI948. When you use the remarkup hint button to embed a meme with no text, you get `{meme src=X}`.
If the source is a GIF, we currently split the source apart into frame-by-frame images, process them, and stitch them back together. The end result is the same image we started with, but this process can be slow/expensive, and may timeout for sufficiently large GIFs.
Instead: when there's no text, just return the original image data.
Test Plan:
- Used `{meme src=X}` with no text, got an image faster.
- Used `{meme src=X, above=...}` to add text, got an attempt to add text (which didn't get very far locally since I don't have GD configured).

It does not work: nothing ever triggers it (nothing renders a control with a `slowvote-option` sigil).
At least for now, just remove it. It has a completely separate pathway in the controller and both pathways are buggy, so this makes fixing them easier.

Summary:
Ref T13210. Ref T11908. Add some basic test coverage for the new "%R" introduced in D19764, then convert LiskDAO to implement the "Database + Table Ref" interface.
To move forward, we need to convert all of these (where `%T` is not a table alias):
```counterexample
qsprintf($conn, '... %T ...', $thing->getTableName());
```
...to these:
```
qsprintf($conn, '... %R ...', $thing);
```
The new code is a little simpler (no `->getTableName()` call) which is sort of nice. But we also have a //lot// of `%T` so this is probably going to take a while.
(I'll hold this until after the release cut.)
Test Plan:
- Ran unit tests.
- Browsed around and edited some objects without issues. This change causes a reasonably large percentage of our total queries to use the new code since the LiskDAO builtin queries are some of the most commonly-constructed queries, although there are still ~700 callsites which need to be examined for possible conversion.
