See PHI190. This clarifies the ruleset a bit:
- If you accepted, then the author used "Request Review" explicitly, we now show "Accepted Earlier" instead of "Accepted" in the "Reviewers" list on the main revision page. This makes it sligthly more clear why the revision is back in your review queue without picking through the transaction log.
- Instead of moving all non-current accepts into "Ready to Review", move only voided accepts into "Ready to Review". This stops us from pulling older accepts which haven't been voided (which could have been incorrectly pulled) and correctly pulls older, voided accepts from before an update (for example: accept, then request review, then update) and generally aligns better with intent/expectation.

- Accepted, requested review.

Notably, this method does not call `adjustObjectForPolicyChecks(...)` properly, so it can not handle special cases like "creating a project and taking its newly created members into account" for object policies like "Project Members".
Just remove these checks, which are redundant with checks elsewhere.

Summary:
Ref T12539. See PHI190. Currently, each Diff has a `revisionID`, but Revisions do not point at the current active diff. To find the active diff for a given revision, we need to issue a separate query.
Furthermore, this query is inefficient for bulk loads: if we have a lot of revisions, we end up querying for all diff IDs for all those revisions first, then selecting the largest ones and querying again to get the actual diff objects. This strategy could likely be optimized but the query is a mess in any case.
In several cases, it's useful to have the active diff PHID without needing to do a second query -- sometimes for convenience, and sometimes for performance.
T12539 is an example of such a case: it would be nice to refine the bucketing logic (which only depends on active diff PHIDs), but it feels bad to make the page heavier to do it.
For now, this is unused. I'll start using it to fix the bucketing issue, and then we can expand it gradually to address other performance/convenience issues.

These changes made the Diffusion blame view very similar to GitHub's blame view. See D18452 for a before/after of the bulk of these changes; the other revisions are bugfixes.
I think this was generally a step backward, and not motivated by solving a specific problem. I've found the new UI less usable than the old one, and at least one install (see PHI174) also has.
In particular, the revision/commit titles are very bulky and not terribly useful; the date column also isn't terribly useful; the "age" color actually IS pretty useful and was heavily de-emphasized.
I've kept one bugfix here (missing `'a'` tag type) and kept the upgraded icon for "Skip Past This Commit".
I'm going to follow this up with some additional changes:
- Show a small author profile icon, similar to GitHub, to address PHI174 more directly.
- Try a zebra-stripe on blocks of rows to make it more clear where changes affected by a particular commit begin and end.
- Try a hue shift, not just a brightness/saturation shift, to make the "age" color more distinct.
- Try computing colors as even steps, not based purely on age. Currently, if a file has one long-distant commit and several recent commits, all the recent ones show up as very bright green. I think this would probably be more useful if they were distributed more evenly across the available color bands.

Summary:
Ref T2543. Fixes T10109.
Currently, Herald only runs in Differential when a change updates the diff. This is partly for historical reasons, and partly because we don't want to restart builds every time someone makes a comment. However, this behavior is inconsistent with other applications (which always trigger on any change), and occasionally confusing to users (in T10109, for example) or otherwise undesirable.
A similar issue is that T2543 has introduced a "Draft" state, where revisions don't send normal mail until builds finish. This interacts poorly with "Send me an email" rules (which shouldn't do anything here) and particularly with "Send me an email + only run these actions the first time the rule matches", since that might have an effect like "do nothing when the revision is created, then never anything again since you already did nothing once".
To navigate both of these issues, let objects tell Herald that certain actions (like mail or builds) are currently forbidden. If a rule uses a field or action which is currently forbidden, the whole rule automatically fails before it executes, but doesn't count toward "only the first time" as far as Herald's tracking of rule execution is concerned.
Then, forbid mail for draft revisions, and forbid builds for revisions which didn't just get updated. Forbidding mail fixes the issues with "Send me an email" that were created by the introduction of the draft state.
Finally, make Herald run on every revision update, not just substantive updates to the diff. This resolves T10109.

Created revisions via the draft -> submit workflow, saw different transcripts. Here's a mail action being forbidden for a draft:

In doing this, we ignore builds with only autotargets, since these are client-side and failures from local `arc lint` / `arc unit` should not count (the user has already chosen to ignore/skip them).
The way we do this has some issues:
- Herald may have started builds, but they may still be PENDING and not have any targets yet. In this case, we'll see "no non-autotargets" and ignore the build, which is wrong.
- We have to load targets but don't really care about them, which is more work than we really need to do.
- And it's kind of complex, too.
Instead, just let `BuildQuery` filter out "autobuilds" (builds generated from autoplans) with a JOIN.

Summary:
See PHI158. In the RefEngine, we test if any old branch positions have been removed from the repository. This is uncommon (but not impossible) in Mercurial, and corresponds to users deleting branches in Git.
Currently, we end up running `hg log` for each position, in parallel. Because of Python's large startup overhead, this can be resource intensive for repositories with a large number of branches.
We have to do this in the general case because the caller may be asking us to resolve `tip`, `newfeature`, `tip~3`, `9`, etc. However, in the specific case where the refs are 40-digit hashes, we can bulk resolve them if they exist, like this:
```
hg log ... --rev (abcd or def0 or ab12 or ...)
```
In the general case, we could probably do less of this than we currently do (instead of testing all old heads, we could prune the list by removing commits which we know are still pointed to by current heads) but that's a slightly more involved change and the effect here is already dramatic.
Test Plan:

Summary: Ref T2543. This is a less ambitious version of the rule in D18628, which I backed off from, since I think this probably still has a fair number of loose ends to tie up.

Summary:
Ref T13000. Since other changes have generally made the ngrams table manageable, I'm not planning to enable common ngrams by default at this time.
Instead, make the threshold configurable with "--threshold" so we can guide installs through tuning this if they want (e.g. PHI110), and tune hosted instances.
(This might eventually become automatic, but just smoothing this bit off for now feels reasonable to me.)
Test Plan: Ran with `--reset`, and with various invalid and valid `--threshold` arguments.

Summary:
Ref T13008. We haven't hit any issues with this, but I can imagine we might in the future.
When one host makes an intracluster request to another host, the `$viewer` ends up as the omnipotent viewer. This viewer isn't logged in, so they'll currently accumulate rate limit points at a high rate.
Instead, don't give them any points. These requests are always legitimate, and if they originated from a user request, that request should be the one getting rate limited.
Test Plan: Browsed around.

Summary:
Ref T13000. The new approach for dumping database-by-database means that we don't get CREATE DATABASE or USE statements, which makes importing the dump again inconvenient.
Manually stitch these into the dump.
Test Plan:
- Used `bin/storage dump --namespace ...` to dump a smaller local instance.
- Used `bin/storage destroy --namespace ...`, to destroy the namespace, then inported the dump cleanly.
- Verified that each CREATE DATABASE statement appears only once.
- Verified that `bin/storage renamespace --live` can correctly process this file.

Summary:
Depends on D18702. Ref T13008. This replaces the old hard-coded single rate limit with multiple flexible limits, and defines two types of limits:
- Rate: reject requests if a client has completed too many requests recently.
- Connection: reject requests if a client has too many more connections than disconnections recently.
The connection limit adds +1 to the score for each connection, then adds -1 for each disconnection. So the overall number is how many open connections they have, at least approximately.
Supporting multiple limits will let us do limiting by Hostname and by remote address (e.g., a specific IP can't exceed a low limit, and all requests to a hostname can't exceed a higher limit).
Configuring the new limits looks something like this:
```
PhabricatorStartup::addRateLimit(new PhabricatorClientRateLimit())
->setLimitKey('rate')
->setClientKey($_SERVER['REMOTE_ADDR'])
->setLimit(5);
PhabricatorStartup::addRateLimit(new PhabricatorClientConnectionLimit())
->setLimitKey('conn')
->setClientKey($_SERVER['REMOTE_ADDR'])
->setLimit(2);
```
Test Plan:
- Configured limits as above.
- Made a lot of requests, got cut off by the rate limit.
- Used `curl --limit-rate -F 'data=@the_letter_m.txt' ...` to upload files really slowly. Got cut off by the connection limit. With `enable_post_data_reading` off, this correctly killed the connections //before// the uploads finished.
- I'll send this stuff to `secure` before production to give it more of a chance.

Summary:
Ref T13008. Depends on D18701. The overall goal here is to make turning `enable_post_data_reading` off not break things, so we can run rate limiting checks before we read file uploads.
The biggest blocker for this is that turning it off stops `$_FILES` from coming into existence.
This //appears// to mostly work. Specifically:
- Skip the `max_post_size` check when POST is off, since it's meaningless.
- Don't read or scrub $_POST at startup when POST is off.
- When we rebuild REQUEST and POST before processing requests, do multipart parsing if we need to and rebuild FILES.
- Skip the `is_uploaded_file()` check if we built FILES ourselves.
This probably breaks a couple of small things, like maybe `__profile__` and other DarkConsole triggers over POST, and probably some other weird stuff. The parsers may also need more work than they've received so far.
I also need to verify that this actually works (i.e., lets us run code without reading the request body) but I'll include that in the change where I update the actual rate limiting.
Test Plan:
- Disabled `enable_post_data_reading`.
- Uploaded a file with a vanilla upload form (project profile image).
- Uploaded a file with drag and drop.
- Used DarkConsole.
- Submitted comments.
- Created a task.
- Browsed around.
