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.

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.

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.

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.

Summary:
Fixes T12145. Ref T13210. See PHI570. See PHI536.
Currently, when you give Drydock an Almanac host pool with more than one host, it never voluntarily builds a second host resource: there is no way to say "maximum X working copies per host" (only "maximum X global working copies") to make the first host overflow, and the allocator tries to pack resources as tightly as possible.
If you can force it to allocate the 2nd..Nth host, things will work reasonably well from there (it will spread working copies across the hosts randomly), but tricking it is very hard, especially before D19761.
To deal with this, give blueprints a new behavior around "supplemental allocations". The idea here is that a blueprint may decide that it would prefer to allocate a fresh new resource instead of allowing an otherwise valid acquisition to occur.
These supplemental allocations follow all the normal allocation rules (they can't exceed limits or actually replace existing resources), so they can only happen if there's free space in the resource pool. But a blueprint can elect for a supplemental allocation to provide a "grow the pool" hint.
The only useful policies here are probably "true" (immediately use all resources, like Almanac) or "false" (pack resources as efficiently as possible) but some other policies //might// be useful (perhaps "start growing the pool when we're getting a bit full even if we aren't at the limit yet, since our workload is bursty").
Then, give Almanac host resources a "true" policy (always allocate supplemental resources) so they use all hosts once a similar number of concurrent jobs arrive.
One aspect of this approach is that we only do supplemental resources if the normal allocation algorithm already decided that the best resource to acquire was part of the same blueprint. I started with an approach like "look at all the blueprints and see if any of them want to be greedy", but then a not-very-desirable blueprint would end up filling up its whole pool before we skipped the supplemental allocation part and ended up picking a different resource. That felt a bit silly and this feels a little cleaner and more focused.
Test Plan:
- Without changing the Almanac blueprint policy, allocated hosts. Got A, A, A, A, ... (second host never used).
- Changed the Almanac policy.
- Allocated hosts, got A, B, random mix of A and B.
- Destroyed B. Destroyed all leases on A. Allocated. Got A. This tests the "don't build a supplemental resource if there are no leases on the natural resource".

Summary:
Depends on D19753. Ref T13210. This is a small optimization that saves us from waiting up to 15 seconds for a yield.
When there are no Working Copy resources and a new lease comes in, we'll allocate one and yield until it activates.
If activating it (SSH'ing and running `git clone`) takes less than 15 seconds, the resource will activate (say, at T+4) but the lease won't update again for a while (say, until T+15). This leaves us with a pointless wait (in this example, we're sitting around for 9 seconds when we could move forward).
To improve this a little bit, let resources wake up the lease update tasks that triggered allocation after they activate. In the best case, that task runs ~15 seconds sooner. In the worst case, the awaken is just a no-op.
With a more-full queue, this has a smaller effect (it's likely something else will run and be able to use the resource in those 9 seconds).
With already-activated resources, this has no effect (when resources are already activated, we can lease immediately).
Test Plan:
- Cleaned up all working copy resources.
- Requested a new "A" working copy.
- Before patch: got a working copy after 17-18 seconds, most of which was spent yielded.

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).

# when performing a read, we can go to any node (currently random, but T10884 discusses ideas to improve our ranking);
# when performing an internal synchronization before a read or a write, we must go to an up-to-date node.
Currently, case (3) is not-exactly-deterministic but not random, and we won't spread intracluster traffic acrosss the cluster evenly if, say, half of it is up to date and half of it is still synchronizing. For a given write, I believe all nodes will tend to synchronize from whichever node first received the write today.
Instead, shuffle the list and synchronize from any up-to-date node.
(I think we could improve upon this only by knowing which nodes actually have load and selecting the least-loaded -- doable, but not trivial.)

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.

See PHI920. Ref T13210. Since the HTML is just:
```
<a>View Inline</a><span>filename.txt</span>
```
..double-clicking "filename.txt" in email selects "Inlinefilename.txt".
Add a space to stop this. At least in Safari, a space between the tags is not sufficient (perhaps because the parent is a `<div>`?). I couldn't find an authoritative-seeming source on what the rules for this actually are and adding a space here fixes the issue without changing the visual rendering, so just put it here.
Test Plan:
- Made an inline.
- Used `bin/mail show-outbound --id ... --dump-html` to dump the HTML.
- Double-clicked the filename.

Summary:
Depends on D19743. Ref T13210. Since this command can easily dump a bunch of binary data (or just a huge long blob of nonsense) to stdout, default to requiring "--output <file>".
Using `--output -` will print to stdout.
Test Plan: Ran with: no `--output`, `--output file`, `--output -`, `--output - --overwrite`. Got sensible results or errors in all cases.

Summary:
Ref T13210. Minor usability improvements to "bin/bulk export":
- Allow `--class task` to work (previously, only `--class ManiphestTaskSearchEngine` worked).
- If you run `--query jXIlzQyOYHPU`, don't require `--class`, since the query identifies the class on its own.
- Allow users to call `--query A --query B --query C` and get a union of all results.
Test Plan:
- Ran `--class task`, `--query A --query B`, `--query X` (with no `--class`), got good results.
- Ran various flavors of bad combinations (queries from different engines, invalid engines, query and class differing, ambiguous/invalid `--class` name) and got sensible errors.

Summary:
Ref T13202. See PHI900. Fixes T12814. Pholio currently builds HTML comments in an older way that can dump a bunch of over-escaped HTML into mail bodies.
Update the logic to be more similar to the Differential rendering logic and stop over-escaping things.
The result isn't perfect, but is dramatically less broken.

Summary:
Ref T13202. See PHI906. This is a reasonable capability which we support in some other applications already.
(The only real reason not to support this is that it creates some clutter in the UI, but I think we're generally in better shape now than we were in the past, and we could make this UI collapse/fold at some point.)
Test Plan: Ran queries with a minimum date, a maximum date, both, and neither. Saw appropriate results in all cases.

Ref T13202. See <https://discourse.phabricator-community.org/t/2fa-input-box-isnt-hinted-as-a-password-so-browsers-suggest-auto-fills/1959>.
If browsers are autofilling this, I think browser behavior here is bad, but behavior is probably better on the balance if we hint this as `autocomplete="off"` and this is a minor concesssion.
Test Plan:
- I couldn't immediately get any browser to try to autofill this field (perhaps I've disabled autofill, or just not enabled it aggressively?), but this change didn't break anything.
- After the change, answered a TOTP prompt normally.
- After the change, inspected page content and saw `autocomplete="off"` on the `<input />` node.

Summary:
Ref T13202. See PHI903 and PHI894. When a bot leaves 100 inline comments on the same file and the revision has a 30-member recipient list, we currently highlight the file 3000 times when building mail.
Instead, engage the parse cache so we highlight it once and reuse the cache 2,999 times.
Test Plan:
- Added debugging code to stop after mail generation and show cache hits/misses.
- Left a bunch of inlines in a file.
- Ran the worker with `bin/worker execute --id ...`.
- Before change: saw 4 comments x 2 recipients = 8 cache misses
- After change: saw 8 cache hits (cache already filled from web UI rendering)
- Removed debugging code, ran worker to completion.
- Used `bin/mail show-outbound --id ... --dump-html` to inspect resulting mail, saw no functional differences.

Summary:
Ref T13202. See PHI889. If the lock log is enabled, we can try to offer more details about lock holders.
When we fail to acquire a lock:
- check for recent acquisitions and suggest that this is a bottleneck issue;
- if there are no recent acquisitions, check for the last acquisition and print details about it (what process, how long ago, whether or not we believe it was released).
Test Plan:
- Enabled the lock log.
- Changed the lock wait time to 1 second.
- Added a `sleep(10)` after grabbing the lock.
- In one window, ran a Conduit call or a `git fetch`.
- In another window, ran another operation.
- Got useful/sensible errors for both ssh and web lock holders, for example:
> PhutilProxyException: Failed to acquire read lock after waiting 1 second(s). You may be able to retry later. (This lock was most recently acquired by a process (pid=12609, host=orbital-3.local, sapi=apache2handler, controller=PhabricatorConduitAPIController, method=diffusion.rawdiffquery) 3 second(s) ago. There is no record of this lock being released.)

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.

Summary:
Ref T13202. In D19660, I added comments to Phriction and tweaked some CSS.
One of these tweaks was getting rid of an extra border which was rendering under the comment area. However, I took off too much and ended up removing borders from other applications.
I think we don't actually need this `setNoBorder()` stuff after all -- a later change was sufficient to stop the actual border I was trying to get rid of from rendering. So this mostly just reverts part of D19660.
This rendering still isn't perfect, but I'm fine leaving that for another day for now.
Test Plan:
- Viewed comment areas in Phriction. Saw correct number of borders (1).
- Viewed comment areas in Maniphest. Saw correct number of borders (1).
- Grepped for extraneous removed classs, no hits.

Depends on D19682. Ref T13202. We currently fatal when trying to render a timeline if:
- an install is fresh, so there are no pages yet, and you look at "/w/"; or
- you're looking at a Phriction page which doesn't exist (yet) like "/w/aadsflknadsflnf/".
Rendering a timeline and comment area doesn't make sense in these cases, so don't render them.

Summary:
Ref T13202. See PHI881. These stories have bad rendering methods, but they didn't previously render into the timeilne (since Phriction documents didn't have a timeline).
Update the rendering to work.
The rendered outcome isn't great (it isn't very clear or explicit about exactly what moved where), but I'll fix that in a followup. This is a net improvement since it doesn't fatal the page, at least.
Test Plan:
- Moved page "X" to "Y".
- Viewed the old page "X".
- Before patch: bad timeline story would fatal rendering.
- After patch: story renders, at least, just not great.
