Summary:
We need to go slightly farther to stub reply handler functionality for Ponder in at least some configurations, where we rely on the presence of a unique random key to generate per-object or per-object+user reply addresses.
This should probably be formalized in an interface since it's currently pretty ad-hoc.
Test Plan:
- Made comments in Ponder under a per-user email configuration.
- Ran migration, verified mail keys were generated.
- Ran migration again (with --apply), verified existing questions were skipped.
- Created a new question, verified mail key generation.

Summary:
People have occasionally complained about phabricator being slow. We have
the access log to look at to see when slowness happens, but it doesn't tell
us much about why it happened. Since it's usually a sporadic issue that's
reported, it's hard to reproduce and then profile. This change will allow us
to collect sampled profiles so we can look at them when slowness occurs.
Test Plan:
checking that sampling works correctly:
- set rate to 0; do several page loads; check no new entries in table
- set rate to 1; check that there's a new row in the table for each page load
- set rate to 10; check that some requests write to table and some don't
check new ui for samples:
- load /xhprof/list/all/, see a list with a lot of samples
- load /xhprof/list/sampled/, see only sampled runs
- load /xhprof/list/manual/, see only non-sampled runs
- load /xhprof/list/my-runs/, se only my manual runs

Summary:
To make it easier to monitor daemons, let's store their current state
(running, died, exited, or unknown) to the db. The purpose of this is to
provide more information on the daemon console about the status of daemons,
especially when they are running on multiple machines. This is mostly backend
work, with only a few frontend changes. (It is also dependent on a change
to libphutil.)
These changes will make dead or stuck daemons more obvious, and will allow
more work on the frontend to hide daemons (and logs) that have exited cleanly,
i.e. ones we don't care about any more.
Test Plan:
- run db migration, check in db that all daemons were marked as exited
- start up a daemon, check in db that it is marked as running
- open web interface, check that daemon is listed as running
- after daemon has been running for a little bit, check in db that dateModified
is being updated (indicating daemon is properly sending heartbeat)
- kill -9 daemon (but don't run bin/phd yet), and check that db still shows it
as running
- edit daemon db entry to show it as being on a different host, and backdate
dateModified field by 3 minutes, and check the web ui to show that the status
is unknown.
- change db entry to have proper host, check in web ui that daemon status is
displayed as dead. Check db to see that the status was saved.
- run bin/phd stop, and see that the formerly dead daemon is now exited.

Differential Revision: https://secure.phabricator.com/D2946
Summary:
The immediate issue this addresses is T1366, adding a rendering cache to Phriction. For wiki pages with code blocks especially, rerendering them each time is expensive.
The broader issue is that out markup caches aren't very good right now. They have three major problems:
**Problem 1: the data is stored in the wrong place.** We currently store remarkup caches on objects. This means we're always loading it and passing it around even when we don't need it, can't genericize cache management code (e.g., have one simple script to drop/GC caches), need to update authoritative rows to clear caches, and can't genericize rendering code since each object is different.
To solve this, I created a dedicated cache database that I plan to move all markup caches to use.
**Problem 2: time-variant rules break when cached.** Some rules like `**bold**` are time-invariant and always produce the same output, but some rules like `{Tnnn}` and `@username` are variant and may render differently (because a task was closed or a user is on vacation). Currently, we cache the raw output, so these time-variant rules get locked at whatever values they had when they were first rendered. This is the main reason Phriction doesn't have a cache right now -- I wanted `{Tnnn}` rules to reflect open/closed tasks.
To solve this, I split markup into a "preprocessing" phase (which does all the parsing and evaluates all time-invariant rules) and a "postprocessing" phase (which evaluates time-variant rules only). The preprocessing phase is most of the expense (and, notably, includes syntax highlighting) so this is nearly as good as caching the final output. I did most of the work here in D737 / D738, but we never moved to use it in Phabricator -- we currently just do the two operations serially in all cases.
This diff splits them apart and caches the output of preprocessing only, so we benefit from caching but also get accurate time-variant rendering.
**Problem 3: cache access isn't batched/pipelined optimally.** When we're rendering a list of markup blocks, we should be able to batch datafetching better than we do. D738 helped with this (fetching is batched within a single hunk of markup) and this improves batching on cache access. We could still do better here, but this is at least a step forward.
Also fixes a bug with generating a link in the Phriction history interface ($uri gets clobbered).
I'm using PHP serialization instead of JSON serialization because Remarkup does some stuff with non-ascii characters that might not survive JSON.
Test Plan:
- Created a Phriction document and verified that previews don't go to cache (no rows appear in the cache table).
- Verified that published documents come out of cache.
- Verified that caches generate/regenerate correctly, time-variant rules render properly and old documents hit the right caches.

Summary:
- We currently write every PHID we generate to a table. This was motivated by two concerns:
- **Understanding Data**: At Facebook, the data was sometimes kind of a mess. You could look at a random user in the ID tool and see 9000 assocs with random binary data attached to them, pointing at a zillion other objects with no idea how any of it got there. I originally created this table to have a canonical source of truth about PHID basics, at least. In practice, our data model has been really tidy and consistent, and we don't use any of the auxiliary data in this table (or even write it). The handle abstraction is powerful and covers essentially all of the useful data in the app, and we have human-readable types in the keys. So I don't think we have a real need here, and this table isn't serving it if we do.
- **Uniqueness**: With a unique key, we can be sure they're unique, even if we get astronomically unlucky and get a collision. But every table we use them in has a unique key anyway. So we actually get pretty much nothing here, except maybe some vague guarantee that we won't reallocate a key later if the original object is deleted. But it's hard to imagine any install will ever have a collision, given that the key space is 36^20 per object type.
- We also currently use PHIDs and Users in tests sometimes. This is silly and can break (see D2461).
- Drop the PHID database.
- Introduce a "Harbormaster" database (the eventual CI tool, after Drydock).
- Add a scratch table to the Harbormaster database for doing unit test meta-tests.
- Now, PHID generation does no writes, and unit tests are isolated from the application.
- @csilvers: This should slightly improve the performance of the large query-bound tail in D2457.

- We go to great lengths to enforce order stability in Differential revisions, but the implementation is complex and inelegant.
- Some relationships are stored on-object, so we can't pull the inverses easily. For example, Maniphest shows child tasks but not parent tasks.
- I want to add more of these and don't want to continue building custom stuff.
- UIs like the "attach stuff to other stuff" UI need custom branches for each object type.
- Stuff like "allow commits to close tasks" is notrivial because of nonstandard metadata storage.
Provide an association-like "edge" framework to fix these problems. This is nearly identical to associations, with a few differences:
- I put edge metadata in a separate table and don't load it by default, to keep edge rows small and allow large metadata if necessary. The on-edge metadata seemed to get abused a lot at Facebook.
- I put a 'seq' column on the edges to ensure they have an explicit, stable ordering within a source and type.
This isn't actually used anywhere yet, but my first target is attaching commits to tasks for T904.
Test Plan: Made a mock page that used Editor and Query. Verified adding and removing edges, overwriting edges, writing and loading edge data, sequence number generation.
