Summary:
Ref T13222. See PHI873. Ref T9770.
Currently, we support only TOTP MFA. For some MFA (SMS and "push-to-app"-style MFA) we may need to keep track of MFA details (e.g., the code we SMS'd you). There isn't much support for that yet.
We also currently allow free reuse of TOTP responses across sessions and workflows. This hypothetically enables some "spyglass" attacks where you look at someone's phone and type the code in before they do. T9770 discusses this in more detail, but is focused on an attack window starting when the user submits the form. I claim the attack window opens when the TOTP code is shown on their phone, and the window between the code being shown and being submitted is //much// more interesting than the window after it is submitted.
To address both of these cases, start tracking MFA "Challenges". These are basically a record that we asked you to give us MFA credentials.
For TOTP, the challenge binds a particular timestep to a given session, so an attacker can't look at your phone and type the code into their browser before (or after) you do -- they have a different session. For now, this means that codes are reusable in the same session, but that will be refined in the future.
For SMS / push, the "Challenge" would store the code we sent you so we could validate it.
This is mostly a step on the way toward one-shot MFA, ad-hoc MFA in comment action stacks, and figuring out what's going on with Duo.
Test Plan:
- Passed MFA normally.
- Passed MFA normally, simultaneously, as two different users.
- With two different sessions for the same user:
- Opened MFA in A, opened MFA in B. B got a "wait".
- Submitted MFA in A.
- Clicked "Wait" a bunch in B.
- Submitted MFA in B when prompted.
- Passed MFA normally, then passed MFA normally again with the same code in the same session. (This change does not prevent code reuse.)

Ref T13222. Ref T13225. We store a digest of the session key in the session table (not the session key itself) so that users with access to this table can't easily steal sessions by just setting their cookies to values from the table.
Users with access to the database can //probably// do plenty of other bad stuff (e.g., T13134 mentions digesting Conduit tokens) but there's very little cost to storing digests instead of live tokens.
We currently digest session keys with HMAC-SHA1. This is fine, but HMAC-SHA256 is better. Upgrade:
- Always write new digests.
- We still match sessions with either digest.
- When we read a session with an old digest, upgrade it to a new digest.
In a few months we can throw away the old code. When we do, installs that skip upgrades for a long time may suffer a one-time logout, but I'll note this in the changelog.
We could avoid this by storing `hmac256(hmac1(key))` instead and re-hashing in a migration, but I think the cost of a one-time logout for some tiny subset of users is very low, and worth keeping things simpler in the long run.
Test Plan:
- Hit a page with an old session, got a session upgrade.
- Reviewed sessions in Settings.
- Reviewed user logs.
- Logged out.
- Logged in.
- Terminated other sessions individually.
- Terminated all other sessions.
- Spot checked session table for general sanity.

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.

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:
Fixes T13208. See that task for details.
The `clone $query` line is safe if `$query` is a builtin query (like "open").
However, if it's a saved query we clone not only the query parameters but the ID, too. Then when we `save()` the query later, we overwrite the original query.
So this would happen in the database. First, you run a query and save it as the workboard default (query key "abc123"):
| 123 | abc123 | {"...xxx..."} |
Then we `clone` it and change the parameters, and `save()` it. But that causes an `UPDATE ... WHERE id = 123` and the table now looks like this:
| 123 | def456 | {"...yyy..."} |
What we want is to create a new query instead, with an `INSERT ...`:
| 123 | abc123 | {"...xxx..."} |
| 124 | def456 | {"...yyy..."} |
Test Plan:
- Followed reproduction steps from above.
- With just the new `save()` guard, hit the guard error.
- With the `newCopy()`, got a new copy of the query and "View as Query" remained functional without overwriting the original query row.
- Ran migration, saw an affected board get fixed.

Summary:
Depends on D19751. Ref T13210. When Drydock needs to reclaim an existing unused resource in order to build a new resource to satisfy a lease, the lease which triggered the reclaim currently gets thrown back into the pool with a 15-second yield.
If the queue is pretty empty and the reclaim is quick, this can mean that we spend up to 15 extra seconds just waiting for the lease update task to get another shot at building a resource (the resource reclaim may complete in a second or two, but nothing else happens until the yield ends).
Instead, when a lease triggers a reclaim, have the reclaim reawaken the lease task when it completes. In the best case, this saves us 15 seconds of waiting. In other cases (the task already completed some other way, the resource gets claimed before the lease gets to it), it's harmless.
Test Plan:
- Allocated A, A, A working copies with limit 3. Leased a B working copy.
- Before patch: allocation took ~32 seconds.
- After patch: allocation takes ~17 seconds (i.e., about 15 seconds less).

Summary:
Ref T13077. This is mostly just a small cleanup change, even though the actual change is large.
We currently reference content and document objects from one another with `contentID` and `documentID`, but this means that `contentID` must be nullable. Switching to PHIDs allows the column to be non-nullable.
This also supports reorienting some current and future transactions around PHIDs, which is preferable for the API. In particular, I'm adding a "publish version X" transaction soon, and would rather callers pass a PHID than an ID or version number, since this will make the API more consistent and powerful.
Today, `contentID` gets used as a cheaty way to order documents by (content) edit time. Since PHIDs aren't orderable and stuff is going to become actually-revertible soon, replace this with an epoch timestamp.
Test Plan:
- Created, edited, moved, retitled, and deleted Phriction documents.
- Grepped for `documentID` and `contentID`.
- This probably breaks //something// but I'll be in this code for a bit and am likely to catch whatever breaks.

Since Phriction is hierarchical, there isn't a super strong motivation to support Spaces: you can generally set policies on a small number of documents to get the desired effective policy behavior.
However, it still improves consistency and there's no reason //not// to support Spaces. In the case where you have some moderately weird/complex policy on one or more Spaces, using Spaces to define the policy behavior can make things a bit simpler and easier to understand.
This probably doesn't actually fix whatever the root problem in T12435 was (complicated, non-hierarchical access policies?). See also a bunch of discussion in T12442. So we might end up going beyond this to address other use cases, but I think this is reasonable regardless.

Summary:
Ref T13065. `mailKey`s are a private secret for each object. In some mail configurations, they help us ensure that inbound mail is authentic: when we send you mail, the "Reply-To" is "T123+456+abcdef".
- The `T123` is the object you're actually replying to.
- The `456` is your user ID.
- The `abcdef` is a hash of your user account with the `mailKey`.
Knowing this hash effectively proves that Phabricator has sent you mail about the object before, i.e. that you legitimately control the account you're sending from. Without this, anyone could send mail to any object "From" someone else, and have comments post under their username.
To generate this hash, we need a stable secret per object. (We can't use properties like the PHID because the secret has to be legitimately secret.)
Today, we store these in `mailKey` properties on the actual objects, and manually generate them. This results in tons and tons and tons of copies of this same ~10 lines of code.
Instead, just store them in the Mail application and generate them on demand. This change also anticipates possibly adding flags like "must encrypt" and "original subject", which are other "durable metadata about mail transmission" properties we may have use cases for eventually.
Test Plan:
- See next change for additional testing and context.
- Sent mail about Herald rules (next change); saw mail keys generate cleanly.

The complexity of this transaction makes modularizing `AlmanacDevice` transactions tricky. To simplify this, move Interface toward having its own set of normal transactions.
This change just adds some reasonable-looking transactions; it doesn't actually hook them up in the UI or make them reachable. I'll test that they actually work as I swap the UI over.

On the one hand, this is a pretty hacky patch. However, I suspect it inches us closer to T731, and I'm generally comfortable with exploring the realms of "Accept Next Update", "Unblock Without Accepting", etc., as long as most of it doesn't end up enabled by default in the upstream.
Test Plan:
- Accepted and updated revisions normally, saw accepts respect global stickiness.
- Modified the "Accept" action to explicitly be unsticky, saw nonsticky accept behavior after update.

Summary:
See PHI439. This fills in additional information about Owners packages.
Also removes dead `primaryOwnerPHID`.
Test Plan: Called `owners.search` and reviewed the results. Grepped for `primaryOwnerPHID`.

Summary:
Depends on D19182. Ref T11015. This changes `path` from `text255` to `longtext` because paths may be arbitrarily long.
It adds `pathDisplay` to prepare for display paths and storage paths having different values. For now, `pathDisplay` is copied from `path` and always has the same value.
Test Plan:
- Ran migration, checked database for sanity (all `pathDisplay` and `path` values identical).
- Added new paths, saw `pathDisplay` and `path` get the same values.
- Added an unreasonably enormous path with far more than 255 characters.

Summary:
Depends on D19181. Ref T11015. This nukes duplicates from the table if they exist, then adds a unique key.
(Duplicates should not exist and can not be added with any recent version of the web UI.)
Test Plan:
- Tried to add duplicates with web UI, didn't have any luck.
- Explicitly added duplicates with manual `INSERT`s.
- Viewed packages in web UI and saw duplicates.
- Ran migrations, got a clean purge and a nice unique key.
- There's still no way to actually hit a duplicate key error in the UI (unless you can collide hashes, I suppose), this is purely a correctness/robustness change.

Summary: Ref T11015. This supports making path names arbitrarily long and putting a proper unique key on the table.
Test Plan:
- Migrated, checked database, saw nice digested indexes.
- Edited a package, saw new rows update with digested indexes.

Summary: Depends on D19173. Ref T13096. Adds an optional, disabled-by-default lock log to make it easier to figure out what is acquiring and holding locks.
Test Plan: Ran `bin/lock log --enable`, `--disable`, `--name`, etc. Saw sensible-looking output with log enabled and daemons restarted. Saw no additional output with log disabled and daemons restarted.

Summary: Depends on D19148. Ref T13088. The new rendering always executes range requests for data it needs, and we can satisfy these requests by loading the smallest number of chunks which span that range.
Test Plan: Piped 50,000 lines of Apache log into Harbormaster, viewed it in the new UI, got sensible rendering times and a reasonable amount of data actually going over the wire.

Summary:
Depends on D19138. Ref T13088. When we want to read the last part of a logfile //and show accurate line numbers//, we need to be able to get from byte offsets to line numbers somehow.
Our fundamental unit must remain byte offsets, because a test can emit an arbitrarily long line, and we should accommodate it cleanly if a test emits 2GB of the letter "A".
To support going from byte offsets to line numbers, compute a map with periodic line markers throughout the offsets of the file. From here, we can figure out the line numbers for arbitrary positions in the file with only a constant amount of work.
Test Plan: Added unit tests; ran unit tests.

Summary: Depends on D19137. Ref T13088. This allows `rebuild-log` to skip work if the chunks are already compressed. It also prepares for a future GC which is looking for "text" or "gzip" chunks to throw away in favor of archival into Files; such a GC can use this column to find collectable logs and then write "file" to it, meaning "chunks are gone, this data is only available in Files".
Test Plan: Ran migration, saw logs populate as "text". Ran `rebuild-log`, saw logs rebuild as "gzip".

Summary: Depends on D19135. Ref T13088. Denormalize the total log size onto the log itself. This makes reasoning about the log at display time easier, and we don't need to fish around in the database as much to figure out what we're dealing with.
Test Plan: Ran `bin/harbormaster rebuild-log`, saw an existing log populate. Ran `bin/harbormaster write-log`, saw new log write with proper length information.

Summary:
Ref T13083. Facts has a fair amount of weird hardcoding and duplication of responsibilities. Reduce this somewhat: no more hard-coded fact aggregates, no more database-driven list of available facts, etc. Generally, derive all objective truth from FactEngines. This is more similar to how most other modern applications work.
For clarity, hopefully: rename "FactSpec" to "Fact". Rename "RawFact" to "Datapoint".
Split the fairly optimistic "RawFact" table into an "IntDatapoint" table with less stuff in it, then dimension tables for the object PHIDs and key names. This is primarily aimed at reducing the row size of each datapoint. At the time I originally wrote this code we hadn't experimented much with storing similar data in multiple tables, but this is now more common and has worked well elsewhere (CustomFields, Edges, Ferret) so I don't anticipate this causing issues. If we need more complex or multidimension/multivalue tables later we can accommodate them. The queries a single table supports (like "all facts of all kinds in some time window") don't make any sense as far as I can tell and could likely be UNION ALL'd anyway.
Remove all the aggregation stuff for now, it's not really clear to me what this should look like.
Test Plan: Ran `bin/fact analyze` and viewed web UI. Nothing exploded too violently.
