Summary:
Ref T2852. I want to model Asana integration as a response to feed events. Currently, we queue one feed event for each HTTP hook.
Instead, always queue one feed event and then have it queue any necessary followup events (now, http hooks; soon, asana).
Add a script to make it easy to reproducibly fire feed event publishing.
Test Plan:
Republished a feed event and verified it hit configured HTTP hooks correctly.

Summary:
Decided the best approach for refactoring the message/command stuff would be to actually start implementing the campfire adapter to get a better idea of what the abstractions should look like. It feels awkward and unwieldy trying to maintain the irc command interface (notice the message instantiation in the `processReadBuffer()` method. However, i'm still not clear what the best approach is without requiring a re-write of nearly all the existing handlers and defining essentially a custom dsl on top of irc's.
I suppose given that alternative, implementing to irc's dsl doesn't sound all that bad. Just feels like poor coupling.
Also, I know that there is some http stuff in libphutil's futures library, but the https future is shit and I need to do some custom curlopt stuff I wasn't sure how to do with that. But if you think this should be refactored, let me know.
I tested this with the ObjectHandler (messages with DXXX initiate the bot to respond with the title/link just as with irc), but beyond that, I haven't tried any of the other handlers, so if there are complications you think i'm going to run into, just let me know (this is one of the reasons for requesting review early on).
Also, this diff is against my last one, even though that hasn't been merged down yet. It was starting to get large and I'd prefer to keep to two conversations separate.

Summary:
Ugh, just wrote out a huge message, only to lose it with a fat-fingered ctrl-c. Le sigh.
First pass at decoupling the bot from the protocol. Noticeably absent is the command/message coupling. After this design pass I'll give that a go. Could use some advice, thinking that handlers should only create messages (which can be public or private) and not open ended, undefined 'commands'. The problem being that there needs to be some consistant api if we want handlers to be protocol agnostic. Perhaps that's a pipedream, what are your thoughts?
Secondly, a few notes, design review requests on the changes i did make:
# Config. For now i'm passing config through to the adapter. This was mainly to remain backwards compatible on the config. I was thinking it should probably be namespaced into it's own subobject though to distinguish the adapter config from the bot config.
# Adapter selection. This flavor is the one-bot-daemon, config specified protocol version. The upside is that in the future they won't have to run different daemons for this stuff, just have different config, and the door is open for multiple protocol adapters down the road if need be. The downside is that I had to rename the daemon (non-backwards compatible change) and there will need to be some sort of runtime evaluation for instatiation of the adapter. For now I just have a crude switch, but I was thinking of just taking the string they supply as the class name (ala `try { new $clasName(); } catch...`) so as to allow for homegrown adapters, but I wasn't sure how such runtime magic would go over. Also, an alternative would be to make the PhabricatorBot class a non-abstract non-final base class and have the adapters be accompanied by a bot class that just defines their adapter as a property. The upside of which is backwards compatibility (welcome back PhabricatorIRCBot) and perhaps a little bit clearer plugin path for homegrowners.
# Logging. You'll notice I commented out two very important logging lines in the irc adapter. This isn't intended to remain commented out, but I'm not sure what the best way is to get logging at this layer. I'm wary of just composing the daemon back down into the adapter (bi-directional object composition makes my skin crawl), but something needs to happen, obviously. Advice?
That's it. After the feedback on the above, you can either merge down, or wait until i finish the command/message refactor if you don't think the diff will grow too large. Up to you, this all functions as is.
Test Plan: Ran an irc bot, connected, read input, and wrote output including handler integration.

Summary:
Some time ago, we added `ORDER BY id ASC` to the worker `UPDATE ...` query, because someone reported that their MySQL read slaves were complaining about the query (I can't find the exact error message, but something to the effect of the rows the query affected not being deterministic). This seemed harmless since it should be the same as the query's implicit order (I guess?), but actually made the query dramatically slower for large numbers of rows.
On my local machine, this query takes about 2 seconds with ~1M rows. If I run `SELECT`, or run `UPDATE` without ORDER BY, the query takes < 0.01s. I don't understand exactly what's happening -- my guess is something to do with the ORDER BY implying that a lot of rows need to be locked?
In T2372, a user is seeing 20-60s rumtimes on this query.
I solved this by doing a SELECT, followed by an UPDATE. Each query runs quickly. This introduces the possibility of a race (two processes SELECT the same rows, then try to UPDATE), which we currently recover from by having the second UPDATE fail and then having that daemon try again 1 second later. This seems generally reasonable. Some alternatives I considered:
- We could SELECT ... LOCK FOR UPDATE, but failing and retrying a little later seems at least as good as blocking.
- We could select more rows than we need, and then try to lock some of them randomly. I think this would work well, but it's a bit more complex than what we're doing now so I left it until we have a clearer need.
Test Plan:
Inserted ~1M tasks into the queue. Ran `phd debug taskmaster`, saw ~2s task updates. Applied patch. Ran `phd debug taskmaster`, saw <1ms updates. Ran `phd launch 8 taskmaster`, saw rapid completion of tasks.
This stuff also has fairly thorough unit test coverage.

However, other scripts may be long-running or issue a large body of service calls (e.g., `bin/search index --all`). We never retrieve this information from scripts (it is used to build darkconsole; in scripts, we echo it immediately under --trace), so discard it immediately to prevent these scripts from requiring a large amount of memory.
(When the daemons load `__init_script__.php` they end up calling this code, so this doesn't change anything for them. They hit another ServiceProfiler discard along the daemon pathways in libphutil, but the call is idempotent.)

This replaces D4175 and makes it so phabot doesn't message anyone.
The reasons for this are twofold:
- It was possible to get information from the bot, by private messaging it, even
if the bot was only in a +i channel (on a public network) -- meaning that if
someone knew the nickname of the bot, they could obtain e.g. ticket names
or diff titles.
- The other time it messaged people was when you typed e.g. "somenick: T123".
Most times when this is triggered, it's done so on accident.

Under the theory that this is an index size/quality problem (the current index is on a potentially-384-byte field, with many keys sharing prefixes), provide a more general index with fancy new features:
- It implements PhutilKeyValueCache, so it can be a component in cache stacks and supports TTL.

- It automatically compresses large blocks of data (most of what we store is highly-compressible HTML).

Summary:
People hit three issues with D3914:
- As per T2059, we applied a schema change from a `.php` patch, which currently does not work if you use a different user to make schema changes than for normal use.
- Since the change in question is idempotent, just move it to a `.sql` patch. We'll follow up in T2059 and fix it properly.
- Rogue daemons at several installs used old code (expecting autoincrement) to insert into the new table (no autoincrement), thereby creating tasks with ID 0.
- Rename the table so they'll fail.
- This also makes the code a little more consistent.
- Some installs now have tasks with ID 0.
- Use checks against null rather than against 0 so we can process these tasks.
The major issues this fixes are the schema upgrade failure in T2059, and the infinite loops in T2072 and elsewhere.
This isn't really a fully statisfactory fix. I'll discuss some next steps in T2072.

- Remove EC2, RemoteHost, Application, etc., blueprints for now. They're very proof-of-concept and Blueprints are getting API changes I don't want to bother propagating for now. Leave the abstract base class and the LocalHost blueprint. I'll restore the more complicated ones once better foundations are in place.
- Remove the Allocate controller from the web UI. The original vision here was that you'd manually allocate resources in some cases, but it no longer makes sense to do so as all allocations come from leases now. This simplifies allocations and makes the rule for when we can clean up resources clear-cut (if a resource has no more active leases, it can be cleaned up). Instead, we'll build resources like the localhost and remote hosts lazily, when leases come in for them.
- Add some configuration to manage the localhost blueprint.
- Refactor `canAllocateResources()` into `isEnabled()` (for config checks) and `canAllocateMoreResources()` (for quota checks, e.g. too many resources are allocated already).
- Juggle some signatures to align better with a world where blueprints generally do allocate.
- Add some more logging and error handling.
- Fix an issue with log ordering.

Summary:
We lock tasks by setting `leaseOwner` to a unique value, but the value is currently unique-to-the-process rather than unique-to-the-query. This means that if a process leases a task, then leases another task, both tasks will have the same `leaseOwner`. This can cause an issue where we go to select the task we just leased and get the other task instead, if we aren't careful about the select construction.
We can avoid this by being clever and making sure the select is constructed correctly, but making the `leaseOwner` unique to the query is much simpler and more foolproof. This guarantees we always select only the rows we just leased.
Also remove `PhabricatorGoodForNothingWorker` since `PhabricatorTestWorker` fills its role of allowing things to be tested, and simplify the unit tests since we don't need to be clever about avoiding this issue any more.

Summary:
This was the major goal of D3859/D3855, and to a lesser degree D3854/D3852.
As Drydock is allocating a resource, it may need to allocate other resources first. For example, if it's allocating a working copy, it may need to allocate a host first.
Currently, we have the process basically queue up the allocation (insert a task into the queue) and sleep() until it finishes. This is problematic for a bunch of reasons, but the major one is that if allocation takes more resources (host, port, machine, DNS) than you have daemons, they could all end up sleeping and waiting for some other daemon to do their work. This is really stupid. Even if you only take up some of them, you're spending slots sleeping when you could be doing useful work.
To partially get around this and make the CLI experience less dumb, there's this goofy `synchronous` flag that gets passed around everywhere and pushes the workflow through a pile of special cases. Basically the `synchronous` flag causes us to do everything in-process. But this is dumb too because we'd rather do things in parallel if we can, and we have to have a lot of special case code to make it work at all.
Get rid of all of this. Instead of sleep()ing, try to work on the tasks that need to be worked on. If another daemon grabbed them already that's fine, but in the worst case we just gracefully degrade and do everything in process. So we get the best of both worlds: if we have parallelizable tasks and free daemons, things will execute in parallel. If we have nonparallelizable tasks or no free daemons, things will execute in process.
Test Plan: Ran `drydock_control.php --trace` and saw it perform cascading allocations without sleeping or special casing.

Summary:
Currently, when taskmasters complete a task it is immediately deleted. This prevents us from doing some general things, like:
- Supporting the idea of permanent failure (e.g., after N failures just stop trying).
- Showing the user how fast taskmasters are completing tasks.
- Showing the user how long tasks took to complete.
Having better visibility into this is important to Drydock, which builds on the task system. Also, generally buff debug output for task execution.
Test Plan: Ran `bin/phd debug taskmaster`. Ran `bin/phd debug garbage`. Queued some tasks via various systems.

Summary:
See D3126, T1667, T1658. Prior to D3126, `phd` did not use MySQL directly. Now that it does, there are at least two specific problems (see inline comment).
In the long term, we should probably break this dependency and use Conduit. However, we don't currently have access to the daemon log ID and getting it is a mess (the overseer generates it), and I think I want to rewrite how all this works at some point anyway (the daemon calls are currently completely unauthenticated, which is silly -- we should move them to an authenticated channel at some point, I think).
Test Plan: Ran `phd stop` with a bad MySQL config against a non-running daemon, didn't get a query error.

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.

'phd status' should have a stable result when invoked multiple times.
Automatically removing PID files for dead daemons every time 'phd status' is
invoked prevents tools from noticing that a daemon has died if something
happens to invoke 'phd status' before the tool looks. This affects Puppet
noticably, since it probably runs the status command every half hour.
'phd status' may be invoked by tools (such as puppet) which need to make
automated decisions about whether to start/restart the daemon. To enable this,
'phd status' now exits with 0 if all daemons are running, 1 if no daemons are
running, and 2 if some (but not all) daemons are running.

Summary:
- Merge CommitTask daemon into PullLocal daemon. This is another artifact of past instability (and order-dependent parsers). We still publish to the timeline, although this was the last consumer. Long term we'll probably delete timeline and move to webhooks, since everyone who has asked about this stuff has been eager to trade away the durability and ordering of the timeline for the ease of use of webhooks. There's also no reason to timeline this anymore since parsing is no longer order-dependent.
- Add `phd start` to start all the daemons you need. Add `phd restart` to restart all the daemons you need. So cool~
