Depends on D20129. Ref T13244. See PHI1058. When a revision has an "Accept" from a package, count the owners as "involved" in the change whether or not any actual human owners are actually accepting reviewers.
If a user owns "/" and uses "force accept" to cause "/src/javascript" to accept, or a user who legitimately owns "/src/javascript" accepts on behalf of the package but not on behalf of themselves (for whatever reason), it generally makes practical sense that these changes have owners involved in them (i.e., that's what a normal user would expect in both cases) and don't need to trigger audits under "no involvement" rules.
Test Plan: Used `bin/repository reparse --force --owners <commit>` to trigger audit logic. Saw a commit owned by `O1` with a revision counted as "involved" when `O1` had accepted the revision, even though no actual human owner had accepted it.

Ref T13244. See PHI1055. (Earlier, see D20091 and PHI1047.) Previously, we expanded the Owners package autoreview rules from "Yes/No" to several "Review (Blocking) If Non-Owner Author Not Subscribed via Package" kinds of rules. The sky didn't fall and this feature didn't turn into "Herald-in-Owners", so I'm comfortable doing something similar to the "Audit" rules.
PHI1055 is a request for a way to configure slightly different audit behavior, and expanding the options seems like a good approach to satisfy the use case.
Prepare to add more options by moving everything into a class that defines all the behavior of different states, and converting the "0/1" boolean column to a text column.
Test Plan:
- Created several packages, some with and some without auditing.
- Inspected database for: package state; and associated transactions.
- Ran the migrations.
- Inspected database to confirm that state and transactions migrated correctly.
- Reviewed transaction logs.
- Created and edited packages and audit state.

Depends on D20115. See <https://discourse.phabricator-community.org/t/transaction-search-endpoint-does-not-work-on-differential-diffs/2369/>.
Currently, `getApplicationTransactionCommentObject()` throws by default. Subclasses must override it to `return null` to indicate that they don't support comments.
This is silly, and leads to a bunch of code that does a `try / catch` around it, and at least some code (here, `transaction.search`) which doesn't `try / catch` and gets the wrong behavior as a result.
Just make it `return null` by default, meaning "no support for comments". Then remove the `try / catch` stuff and all the `return null` implementations.

Fixes T13192. See PHI1015. When you deactivate a repository, we currently stop serving it.
This creates a problem for intracluster sync, since new nodes can't sync it. If nothing else, this means that if you "ship of theseus" your cluster and turn nodes over one at a time, you will eventually lose the entire repository. Since that's clearly a bad outcome, support sync.
Test Plan:
Testing this requires a "real" cluster, so I mostly used `secure`.
I deactivated rGITTEST and ran this on `secure002`:
```
./bin/repository thaw --demote secure002.phacility.net --force GITTEST && ./bin/repository update GITTEST
```
Before the patch, this failed:

Currently, we don't correctly find linked Bindings when editing a Device, so we may miss Services which have keys that need to be disabled. Instead, discover these linked objects.

In ~2012, the first of these options was added because someone who hates dogs and works at Asana also hated `[Differential]` in the subject line. The use case there was actually //removing// the text, not changing it, but I made the prefix editable since it seemed like slightly less of a one-off.
These options are among the dumbest and most useless config options we have and very rarely used, see T11760. A very small number of instances have configured one of these options.
Newer applications stopped providing these options and no one has complained.
You can get the same effect with `translation.override`. Although I'm not sure we'll keep that around forever, it's a reasonable replacement today. I'll call out an example in the changelog to help installs that want to preserve this option.
If we did want to provide this, it should just be in {nav Applications > Settings} for each application, but I think it's wildly-low-value and "hack via translations" or "local patch" are entirely reasonable if you really want to change these strings.

Summary:
Depends on D19919. Ref T11351. This method appeared in D8802 (note that "get...Object" was renamed to "get...Transaction" there, so this method was actually "new" even though a method of the same name had existed before).
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.

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.

See <https://discourse.phabricator-community.org/t/cannot-accept-commits-in-audit/2166/>.
In D19842, I changed `PhabricatorEditField->shouldGenerateTransactionsFromComment()`.
- Previously, it bailed on `getIsConduitOnly()`.
- After the patch, it bails on a missing `getCommentActionLabel()`.
The old code was actually wrong, and it was previously possible to apply possibly-invalid actions in some cases (or, at least, sneak them through this layer: they would only actually apply if not validated properly).
In practice, it let a different bug through: we sometimes loaded commits without loading their audit authority, so testing whether the viewer could "Accept" the commit or not (or take some other actions like "Raise Concern") would always fail and throw an exception: "Trying to access data not attached to this object..."
Fixing the insufficiently-strict transaction generation code exposed the "authority not attached" bug, which caused some actions to fail to generate transactions.
This appeared in the UI as either an unhelpful error ("You can't post an empty comment") or an action with no effect. The unhelpful error was because we show that error if you aren't taking any //other// actions, and we wouldn't generate an "Accept" action because of the interaction of these bugs, so the code thought you were just posting an empty comment.
Test Plan: Without leaving comments, accepted and rejected commits. No more error messages, and actions took effect.

- 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.

Differential Revision: https://secure.phabricator.com/D19793
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 T13109. Ref T13202. See PHI905. See PHI889. When we receive a write to a repository cluster, we currently send it to a random writable node.
Instead, we can prefer:
- the node currently holding the write lock; or
- any node which is already up to date.
These should simply be better nodes to take writes in all cases. The write lock is global for the repository, so there's no scaling benefit to spreading writes across different nodes, and these particular nodes will be able to accept the write more quickly.
Test Plan:
- This is observable by using `fprintf(STDERR, "%s\n", ...)` in the logic, then running `git push`. I'd like to pull this routing logic out of `PhabricatorRepository` at some point, probably into a dedicated `ClusterURIQuery` sort of class, but that is a larger change.
- Added some `fprintf(...)` stuff around which nodes were being selected.
- Added a `sleep(10)` after grabbing the write lock.
- In one window, pushed. Then pushed in a second window.
- Saw the second window select the lock holder as the write target based on it currently holding the lock.
- Without a concurrent push, saw pushes select up-to-date nodes based on their up-to-date-ness.

Summary:
Ref T13202. See PHI889. Update the read and write locks to the modern parameterized verison, which handles hashing/normalization and can store better logs.
This parameterized mode was added in D19173 and has been used successfully for some time, but not all locks have switched over to it yet.
Test Plan:
- Added an `fprintf(STDERR, $full_name)` to the lock code.
- Pulled a repository.
- Saw sensible lock name on stdout before "acquired read lock...".
- Additional changes in this patch series will vet this more completely.

Fixes T12251. Ref T13189. See PHI610. The difficulty here is that we don't want to disclose Phabricator account information to Buildkite. We're comfortable disclosing information from `git`, etc.
- For commits, use the Identity to provide authorship information from Git.
- For revisions, use the local commit information on the Diff to provide the Git/Mercurial/etc author of the HEAD commit.
Test Plan:
- Built commits and revisions in Buildkite via Harbormaster.
- I can't actually figure out how to see author information on the Buildkite side, but the values look sane when dumped locally.
