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.
Test Plan:
- Ran migrations, inspected database, saw sensible values.
- Created a new revision, saw a sensible database value.
- Updated an existing revision, saw database update properly.

Summary:
See PHI185. When looking at a revision, you can Command-Click (Mac) symbols to jump to their definitions (provided the symbol index has been built).
Currently, the code works on any node inside the changeset list, so it activates when clicking links inside inline comments and opening them in a new window.
To avoid this, don't activate if we're inside an inline comment. This technically prevents you from doing a symbol lookup on a symbol inside a codeblock inside an inline, but that seems fine/reasonable.
Test Plan: Wrote `Dxxx` in an inline, command-clicked it. Before: got a symbol lookup. After: just a new tab with the revision.

Ref T2543. Fixes two relatively minor things:
- When builds finish in Harbormaster, send mail "From" the author.
- Set the `firstBroadcast` flag so that initial mail picks up earlier history (notably, the "reviewers" line).
For now, I'm not setting `firstBroadcast` on explicit "Request Review" (but maybe we should), and not trying to deal with weird cases where you leave a bunch of comments on a draft. Those might be fine as-is or may get tweaked later.

- 12ae08b6b1 / D18473
- 0a01334172 / D18462
- ac91ab1ef9 / D18452
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.
Test Plan:
Viewed blame views in Diffusion, saw a more compact UI similar to the old UI.

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.

- 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);
```

- 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.

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.

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.
Test Plan: This is difficult to test convincingly locally, since I can't reproduce the original issue. It still works after these changes, but it worked fine before these changes too.

Summary:
Ref T13000. Currently, queries can only be executed from the web UI, which requires logging in as a user. I really want to avoid doing that wherever we can, but being able to execute queries on an instance (and, particularly, see the ngrams and timings on the underlying lookups) would have been helpful in several cases.
Improve tooling a bit in advance of the "common ngrams" stuff going out since it seems likely that it will be useful if issues arise.
Test Plan: Ran `bin/search query --query ...`, got useful minimal output. Ran with `--trace` to get internals.

Summary:
Ref T13000. After an ngram is marked as "common", we can delete it from the storage table.
Currently, the only way to get ngrams marked as "common" is to manually run `bin/search ngrams`, so this has no impact on normal installs.
Test Plan: Ran `bin/garbage collect`, saw it start chewing through my local Maniphest ngrams table and removing common ngrams.

Summary:
Ref T13000. This marks each table as either "data" (normal data), "cache" (automatically rebuilt, no need to ever dump) or "index" (can be manually rebuilt).
By default, `bin/storage dump` dumps data and index tables, but not cache tables.
With `--no-indexes`, it dumps only data tables. Indexes can be rebuilt after a restore with `bin/search index --all ...`.
Test Plan:
- Ran `--no-indexes` and normal dumps with `--trace`, verified that cache and index (former case) or cache only (latter case) tables were dumped with `--no-data`.
- Verified dump has the same number of `CREATE TABLE` statements as before the changes.
- Reviewed persistence tags in the web UI (note Ferret engine tables are "Index"):

Maniphest Tasks: T13000
Differential Revision: https://secure.phabricator.com/D18682
Summary:
Ref T13000. This allows us to be more selective about which tables we dump data for, to reduce the size of backups and exports. The immediate goal is to make large `ngrams` tables more manageable in the cluster, but this generally makes all backups and exports faster and easier.
Here, tables are dumped one at a time. A followup change will sometimes add the `--no-data` flag, to skip dumping readthrough caches and (optionally) rebuildable indexes.
Test Plan: Compared a dump from `master` and from this branch, found them to be essentially identical. The new dump has a little more header information in each section. Verified each contains the same number of `CREATE TABLE` statements.
