Summary:
Fixes T5855. Adds a `--graceful N` flag to `phd stop` and `phd restart`.
`phd` will send SIGINT, wait `N` seconds, SIGTERM, wait 15 seconds, and SIGKILL. By default, `N` is 15.
Test Plan:
- Ran `bin/phd debug ...` and used `^C` to interrupt daemons. Saw graceful shutdown behavior, and abrupt termination on multiple `^C`.
- Ran `bin/phd start`, `bin/phd stop` and `bin/phd restart` with `--graceful` set to various things, notably `0`. Saw graceful shutdowns on the CLI and in the web UI. With `0`, abrupt shutdowns.

Restores functionality for Flowdock->Chatbot adapter.
Most likely the result of API changes in the year since the original patch was contributed,
the flowdock adapter no longer worked.
This makes a few tweaks to both the base streaming adapter class and the flowdock adpater. I took care to not disturb the functionality of the campfire adapter, but I don't have any way to test it.

Summary: Fixes T5336. Currently, `PhabricatorWorkerLeaseQuery` is basically FIFO. It makes more sense for the queue to be a priority-queue, and to assign higher priorities to alerts (email and SMS).

Started a `PhabricatorTaskmasterDaemon` and verified that the higher priority tasks were executed before lower priority tasks.

Summary:
For Harbormaster tasks which want to poll or wait, this lets them say "try again a little later" without having to sleep and hold a queue slot.
This is basically the same as failing, except that we don't increment the failure counter. Instead, we just set the current lease to the correct length and then exit. The task will be retried after the lease expires.
Test Plan: Using both `bin/harbormaster` and `phd debug taskmaster`, ran a lot of waiting tasks through the queue, faking them to either yield or not yield in a controlled manner. The queue responded as expected, yielding tasks appropraitely and retrying them later.

Summary:
See discussion in D8773. Three small adjustments which should help prevent this kind of issue:
- When queueing followup tasks, hold them on the worker until we finish the task, then queue them only if the work was successful.
- Increase the default lease time from 60 seconds to 2 hours. Although most tasks finish in far fewer than 60 seconds, the daemons are generally stable nowadays and these short leases don't serve much of a purpose. I think they also date from an era where lease expiry and failure were less clearly distinguished.
- Increase the default wait-after-failure from 60 seconds to 5 minutes. This largely dates from the MetaMTA era, where Facebook ran services with high failure rates and it was appropriate to repeatedly hammer them until things went through. In modern infrastructure, such failures are rare.
Test Plan:
- Verified that tasks queued properly after the main task was updated.
- Verified that leases default to 7200 seconds.
- Intentionally failed a task and verified default 300 second wait before retry.
- Removed all default leases shorter than 7200 seconds (there was only one).
- Checked all the wait before retry implementations for anything much shorter than 5 minutes (they all seem reasonable).

Summary:
Ref T2015. Currently, Drydock has a `wait-for-lease` workflow which is invoked in the background by the `lease` workflow.
The goal of this mechanism is to allow `bin/drydock lease` to print out logs as the lease is acquired. However, this predates the `runAllTasksInProcess` flags, and they provide a simpler and more robust way (potentially with `--trace` and `PhutilConsole`) to do synchronous execution and debug logging.
Simplify this whole mechanism: just run everything in-process in `bin/drydock lease`, and do logging via `--trace`. We could thread a `PhutilConsole` through things too, but this seems good enough for now.
Also various cleanup/etc.
Test Plan: Ran `bin/drydock lease`. Ran `bin/harbormaster build X --plan Y`, for `Y` being a Drydock-dependent build plan.

Ref T1049. See discussion in D7745. We have some specific interest in this for D7745, but generally we want to consume tasks with expired leases in roughly FIFO order, just like we consume new tasks in roughly FIFO order. Currently, when we select an expired task we order them by `id`, but this is the original insert order, not lease expiration order. Instead, order by `leaseExpires`.
This query is actually much better than the old one was, since the WHERE part is `leaseExpries < VALUE`.

Summary:
Ref T2230. When fully set up, we have up to three users who all need to write into the repositories:
- The webserver needs to write for HTTP receives.
- The SSH user needs to write for SSH receives.
- The daemons need to write for "git fetch", "git clone", etc.
These three users don't need to be different, but in practice they are often not likely to all be the same user. If for no other reason, making them all the same user requires you to "git clone httpd@host.com", and installs are likely to prefer "git clone git@host.com".
Using three different users also allows better privilege separation. Particularly, the daemon user can be the //only// user with write access to the repositories. The webserver and SSH user can accomplish their writes through `sudo`, with a whitelisted set of commands. This means that even if you compromise the `ssh` user, you need to find a way to escallate from there to the daemon user in order to, e.g., write arbitrary stuff into the repository or bypass commit hooks.
This lays some of the groundwork for a highly-separated configuration where the SSH and HTTP users have the fewest privileges possible and use `sudo` to interact with repositories. Some future work which might make sense:
- Make `bin/phd` respect this (require start as the right user, or as root and drop privileges, if this configuration is set).
- Execute all `git/hg/svn` commands via sudo?
Users aren't expected to configure this yet so I haven't written any documentation.
Test Plan:
Added an SSH user ("dweller") and gave it sudo by adding this to `/etc/sudoers`:
dweller ALL=(epriestley) SETENV: NOPASSWD: /usr/bin/git-upload-pack, /usr/bin/git-receive-pack
Then I ran git pushes and pulls over SSH via "dweller@localhost". They successfully interacted with the repository on disk as the "epriestley" user.

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.)

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.

- 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.

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).

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.

- 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.
