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.

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.

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.

Ref T13110. Currently, build status is published the same way for every Buildable by the BuildEngine.
I want to change this to delegate publishing to each Buildable, particularly so that Differential may use more detailed rules for handling builds and drafts.
Rather than add additional methods to the existing `BuildableInterface`, add an engine generator method instead. This is a pattern which has seen more use recently (e.g., in Ferret) and lets us pay a little more upfront to pull complex pieces of logic out of the main class and let them use inheritence more easily. If we had Traits that might cover this to some degree.
I'd expect to eventually reduce the size of `BuildableInterface` and move the `CircleCI` and `BuildKite` interfaces so that the `BuildableEngine` implements them instead of the main object.
Here, this new engine does nothing and is never instantiated. In upcoming changes, publishing logic will move into it so that Differential can handle publishing differently.

My understanding is that it's an Outlook/Exchange thing, but we also implement "Thread-Index" which I think is what Outlook/Exchange actually look at. This header may have done something before we implemented "Thread-Index", or maybe never done anything. Or maybe older versions of Excel/Outlook did something with it and newer versions don't, or do less. So it's possible that an even better fix here would be to simply remove this, but I wasn't able to convince myself of that after Googling for 10 minutes and I don't think it's worth hours of installing Exchange/Outlook to figure out. Instead, I'm just trying to simplify our handling of this header for now, and maybe some day we'll learn more about Exchange/Outlook and can remove it.
In a number of cases we already use the object monogram or PHID as a "Thread-Topic" without users ever complaining, so I think that if this header is useful it probably isn't shown to users, or isn't shown very often (e.g., only in a specific "conversation" sub-view?). Just use the object PHID (which should be unique and stable) as a thread-topic, everywhere, automatically.
Then allow this header through for "Must Encrypt" mail.
Test Plan: Processed some local mail, saw object PHIDs for "Thread-Topic" headers.

Summary:
Ref T13053. Adds revision stamps (status, reviewers, etc). Adds Herald rule stamps, like the existing X-Herald-Rules header.
Removes the "self" stamps, since you can just write a rule against `whatever(@epriestley)` equivalently. If there's routing logic around this, it can live in the routing layer. This avoids tons of self-actor, self-mention, self-reviewer, self-blocking-reviewer, self-resigned-reviewer, etc., stamps.
Use `natcasesort()` instead of `sort()` so that numeric values (like monograms) sort `9, 80, 700` instead of `700, 80, 9`.
Remove the commas from rendering since they don't really add anything.

Fixes T13031. "Enormous" changes are basically changes which are too large to hold in memory, although the actual definition we use today is "more than 1GB of change text or `git diff` runs for more than 15 minutes".
If an install configures a Herald content rule like "when content matches /XYZ/, do something" and then a user pushes a 30 GB source file, we can't put it into memory to `preg_match()` it. Currently, the way to handle this case is to write a separate Herald rule that rejects enormous changes. However, this isn't obvious and means the default behavior is unsafe.
Make the default behavior safe by rejecting these changes with a message, similar to how we reject "dangerous" changes (which permanently delete or overwrite history) by default.
Also, change a couple of UI strings from "Enormous" to "Very Large" to reduce ambiguity. See <https://discourse.phabricator-community.org/t/herald-enormous-check/822>.
Test Plan: Changed the definition of "enormous" from 1GB to 1 byte. Pushed a change; got rejected. Allowed enormous changes, pushed, got rejected by a Herald rule. Disabled the Herald rule, pushed, got a clean push. Prevented enormous changes again. Grepped for "enormous" elsewhere in the UI.

Summary:
Ref PHI109. Ref T11786. We currently test elapsed time every 64 iterations (since iterations are normally very fast), but at least one install is seeing the page timeout after 30 seconds.
One reason could be that cache fills may occur, and are likely to be much slower than normal iterations. In an extreme case, we could do 64 cache fills before checking the time. Tweak thing so that we always check the time after doing a cache fill, regardless of how many iterations have elapsed since the last attempt.
Additionally, this API method currently accepts an arbitrary number of paths, but implicitly limits each cache query to 500ms. If more than 60 paths are passed, this may exceed 30s. Only let the cache churn for a maximum of 10s across all paths.
If this is more the latter issue than the former, this might replace the GraphCache timeouts with `git` timeouts, but at least our understanding of what's going on here will improve.

Summary:
Ref T11823. Currently, we have a "RefCursor" table which stores rows like `<branch or tag name, commit it is pointing at>` with some more data.
Because Mercurial can have a single branch pointing at several different places, this table must allow multiple rows with the same branch or tag name.
Among other things, this means there isn't a single PHID which can be used to identify a branch name in a stable way. However, we have several UIs where we want to be able to do this.
Some specific examples where we run into trouble: in Mercurial, if there are 5 heads for "default", that means there are 5 phids. And currently, if someone deletes a branch, we lose the PHID for it. Instead, we'd rather retain it so the whole world doesn't break if you accidentally delete a branch and then fix it a little later.
(I'll likely hold this until the rest of the logic is fleshed out a little more in followup changes.)

Summary:
Via HackerOne (<https://hackerone.com/reports/220909>). When we close commits in response to "Fixes Txxx", we currently act as the omnipotent user. This allows users to close tasks they can't see by pushing commits with "Fixes Txxx" in the message.
However, we can't actually tell who authored or committed a change: we're just using the "Author" and "Committer" values from Git in most cases, and anyone can forge those. So we can't really get this right, in a security sense.
(We can tell who //pushed// a change if we host it, but that's often not the right user. If GPG signing was more prevalent, we could use that. In the future, we could use side channels like having `arc land` tell Phabrcator who was pushing changes.)
Since I think the impact of this is fairly minor and this isn't //really// a security issue (more of a confusion/abuse/product issue) I think the behavior is okay more-or-less as-is, but we can do better when we do identify an author: drop permissions, and use their privileges to load the tasks which the commit "fixes".
This effectively implements this rule:
> If we identify the author of a commit as user X, that commit can only affect tasks which user X can see and edit.
Note that:
- Commits which we can't identify the author for can still affect any task.
- Any user can forge any other user's identity (or an invalid identity) and affect any task.
So this is just a guard rail to prevent mistakes by good-faith users who type the wrong task IDs, not a real security measure.
Also note that to perform this "attack" you must already have commit access to a repository (or permission to create a repository).
Test Plan:
- Used `bin/repository reparse --message <commit> --force-autoclose` to run the relevant code.
- Made the code `throw` before it actually applied the edit.
- Verified that the edit was rejected if the author was recognized and can not see or could not edit the task.
- Verified that the edit is accepted if the author can see+edit the task.
- Verified that the edit is accepted if we can't figure out who the author is.

- Origins could be configured to have multiple URIs for some reason, but shouldn't be.
- Years ago, you could configure Phabricator to point at a local repository it didn't own and that could conceivably have a different "origin" that you might not want us to delete. If you did this, the daemons have been spewing errors for 3-4 years without you fixing it. The cost of fixing the remote URI is very small even if anyone is affected by this (just set it back to the old value) and there's zero reason to do this and the scenario is ridiculous.
Test Plan: Ran `bin/repository update PHABX --trace --verbose`, saw fetches go through cleanly after URI adjustment.

Summary:
Ref T12296. Ref T12392. Currently, when we're observing a remote repository, we periodically run `git fetch ...`.
Instead, periodically run `git ls-remote` (to list refs in the remote) and `git for-each-ref` (to list local refs) and only continue if the two lists are different.
The motivations for this are:
- In T12296, it appears that doing this is //faster// than doing a no-op `git fetch`. This effect seems to reproduce locally in a clean environment (900ms for `ls-remote` + 100ms for `for-each-ref` vs about 1.4s for `fetch`). I don't have any explanation for why this is, but there it is. This isn't a huge change, although the time we're saving does appear to mostly be local CPU time, which is good for us.
- Because we control all writes, we could cache `git for-each-ref` in the future and do fewer disk operations. This doesn't necessarily seem too valuable, though.
- This allows us to tell if a fetch will do anything or not, and make better decisions around clustering (in particular, simplify how observed repository versioning works). With `git fetch`, we can't easily distinguish between "fetch, but nothing changed" and "legitimate fetch".
If a repository updates very regularly we end up doing slightly more work this way (that is, if `ls-remote` always comes back with changes, we do a little extra work), but this is normally very rare.
This might not get non-bare repositories quite right in some cases (i.e., incorrectly detect them as changed when they are unchanged) but we haven't created non-bare repositories for many years.
Test Plan: Ran `bin/repository update --trace --verbose PHABX`, saw sensible construction of local and remote maps and accurate detection of whether a fetch would do anything or not.

Summary:
Ref T12296. This cache is used to cache Git ref heads (branches, tags, etc). Reasonable repositories may have more than 2048 of these.
When we miss the cache, we need to single-get refs to check them, which is relatively expensive.
Increasing the size of the cache to 65535 should only require about 7.5MB of RAM.
Additionally, fill only as much of the cache as actually fits. The FIFO nature of the cache can get us into trouble otherwise.
If we insert "A, B, C, D" and then lookup A, B, C, D, but the cache has maximum size 3, we get this:
- Insert A, B, C, D: cache is now "B, C, D".
- Lookup A: miss, single get, insert, purge, cache is now "C, D, A".
- Lookup B: miss, singel get, insert, purge, cache is now "D, A, B".
Test Plan:
- Reduced cache size to 5, observed reasonable behavior on the `array_slice()` locally with `bin/repository update` + `var_dump()`.
- Used this script to estimate the size of 65535 cache entries as 7.5MB:
```
epriestley@orbital ~ $ cat size.php
<?php
$cache = array();
$mem_start = memory_get_usage();
for ($ii = 0; $ii < 65535; $ii++) {
$cache[sha1($ii)] = true;
}
echo number_format(memory_get_usage() - $mem_start)." bytes\n";
epriestley@orbital ~ $ php -f size.php
7,602,176 bytes
```
