Summary:
See discussion in T2221. Before we can move configuration to the database, we have a bootstrapping problem: we need database credentials to live //somewhere// if we can't guess them (and we can only really guess localhost / root / no password).
Some options for this are:
- Have them live in ENV variables.
- These are often somewhat unfamiliar to users.
- Scripts would become a huge pain -- you'd have to dump a bunch of stuff into ENV.
- Some environments have limited ability to set ENV vars.
- SSH is also a pain.
- Have them live in a normal config file.
- This probably isn't really too awful, but:
- Since we deploy/upgrade with git, we can't currently let them edit a file which already exists, or their working copy will become dirty.
- So they have to copy or create a file, then edit it.
- The biggest issue I have with this is that it will be difficult to give specific, easily-followed directions from Setup. The instructions need to be like "Copy template.conf.php to real.conf.php, then edit these keys: x, y, z". This isn't as easy to follow as "run script Y".
- Have them live in an abnormal config file with script access (this diff).
- I think this is a little better than a normal config file, because we can tell users 'run phabricator/bin/config set mysql.user phabricator' and such, which is easier to follow than editing a config file.
I think this is only a marginal improvement over a normal config file and am open to arguments against this approach, but I think it will be a little easier for users to deal with than a normal config file. In most cases they should only need to store three values in this file -- db user/host/pass -- since once we have those we can bootstrap everything else. Normal config files also aren't going away for more advanced users, we're just offering a simple alternative for most users.
This also adds an ENVIRONMENT file as an alternative to PHABRICATOR_ENV. This is just a simple way to specify the environment if you don't have convenient access to env vars.
Test Plan: Ran `config set x y`, verified writes. Wrote to ENVIRONMENT, ran `PHABRICATOR_ENV= ./bin/repository`.

This is somewhat clowny, particularly in how it handles JSON encode/decode, but
I've commented why I did things the way I did. The goal is to store minified JSON
but show pretty-printed JSON where possible, to the user editing it.
Test Plan:
* Went to /config/ and saw a list of keys from the `default` config.
* Clicked on one of them, submitted the default value successfully.
* Changed the value to invalid JSON and got a decent error.
* Changed the value to valid JSON and checked the DB to confirm it saved.
* Confirmed the DB values were minified.
* Confirmed the user-facing values were pretty-printed where they could be.
* Confirmed that PHIDs were getting assigned properly and that isDeleted

Summary:
The search indexing API has several problems right now:
- Always runs in-process.
- It would be nice to push this into the task queue for performance. However, the API currently passses an object all the way through (and some indexers depend on preloaded object attributes), so it can't be dumped into the task queue at any stage since we can't serialize it.
- Being able to use the task queue will also make rebuilding indexes faster.
- Instead, make the API phid-oriented.
- No uniform indexing API.
- Each "Editor" currently calls SomeCustomIndexer::indexThing(). This won't work with AbstractTransactions. The API is also just weird.
- Instead, provide a uniform API.
- No uniform CLI.
- We have `scripts/search/reindex_everything.php`, but it doesn't actually index everything. Each new document type needs to be separately added to it, leading to stuff like D3839. Third-party applications can't provide indexers.
- Instead, let indexers expose documents for indexing.
- Not application-oriented.
- All the indexers live in search/ right now, which isn't the right organization in an application-orietned view of the world.
- Instead, move indexers to applications and load them with SymbolLoader.
Test Plan:
- `bin/search index`
- Indexed one revision, one task.
- Indexed `--type TASK`, `--type DREV`, etc., for all types.
- Indexed `--all`.
- Added the word "saboteur" to a revision, task, wiki page, and question and then searched for it.
- Creating users is a pain; searched for a user after indexing.
- Creating commits is a pain; searched for a commit after indexing.
- Mocks aren't currently loadable in the result view, so their indexing is moot.

Summary:
See discussion in D4204. Facebook currently has a 314MB remarkup cache with a 55MB index, which is slow to access. 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 has a 12-byte hash-based key.
- It automatically compresses large blocks of data (most of what we store is highly-compressible HTML).
Test Plan:
- Basics:
- Loaded /paste/, saw caches generate and save.
- Reloaded /paste/, saw the page hit cache.
- GC:
- Ran GC daemon, saw nothing.
- Set maximum lifetime to 1 second, ran GC daemon, saw it collect the entire cache.
- Deflate:
- Selected row formats from the database, saw a mixture of 'raw' and 'deflate' storage.

Summary:
- Build "sshd-auth" (for authentication) and "sshd-exec" (for command execution) binaries. These are callable by "sshd-vcs", located [[https://github.com/epriestley/sshd-vcs | in my account on GitHub]]. They are based on precursors [[https://github.com/epriestley/sshd-vcs-glue | here on GitHub]] which I deployed for TenXer about a year ago, so I have some confidence they at least basically work.
- The problem this solves is that normally every user would need an account on a machine to connect to it, and/or their public keys would all need to be listed in `~/.authorized_keys`. This is a big pain in most installs. Software like Gitosis/Gitolite solve this problem by giving you an easy way to add public keys to `~/.authorized_keys`, but this is pretty gross.
- Roughly, instead of looking in `~/.authorized_keys` when a user connects, the patched sshd instead runs `echo <public key> | sshd-auth`. The `sshd-auth` script looks up the public key and authorizes the matching user, if they exist. It also forces sshd to run `sshd-exec` instead of a normal shell.
- `sshd-exec` receives the authenticated user and any command which was passed to ssh (like `git receive-pack`) and can route them appropriately.
- Overall, this permits a single account to be set up on a server which all Phabricator users can connect to without any extra work, and which can safely execute commands and apply appropriate permissions, and disable users when they are disabled in Phabricator and all that stuff.
- Build out "sshd-exec" to do more thorough checks and setup, and delegate command execution to Workflows (they now exist, and did not when I originally built this stuff).
- Convert @btrahan's conduit API script into a workflow and slightly simplify it (ConduitCall did not exist at the time it was written).
The next steps here on the Repository side are to implement Workflows for Git, SVN and HG wire protocols. These will mostly just proxy the protocols, but also need to enforce permissions. So the approach will basically be:
- Implement workflows for stuff like `git receive-pack`.
- These workflows will implement enough of the underlying protocol to determine what resource the user is trying to access, and whether they want to read or write it.
- They'll then do a permissons check, and kick the user out if they don't have permission to do whatever they are trying to do.
- If the user does have permission, we just proxy the rest of the transaction.
Next steps on the Conduit side are more simple:
- Make ConduitClient understand "ssh://" URLs.
Test Plan: Ran `sshd-exec --phabricator-ssh-user epriestley conduit differential.query`, etc. This will get a more comprehensive test once I set up sshd-vcs.

Summary:
When a user submits an action with no effect (like an empty comment, an "abandon" on an already-accepted revision, or a "close, resolved" on a closed task) we want to alert them that their action isn't effective. These warnings fall into two general buckets:
- User is submitting two or more actions, and some aren't effective but some are. Prompt them to apply the effective actions only.
- A special case of this is where the only effective action is a comment. We provide tailored text ("Post Comment") in this case.
- User is submitting one action, which isn't effective. Tell them they're out of luck.
- A special case of this is an empty comment. We provide tailored text in this case.
By default, the transaction editor throws when transactions have no effect. The caller can then deal with this, or use `PhabricatorApplicationTransactionNoEffectResponse` to provide a standard dialog that gives the user information as above. For cases where we expect transactions to have no effect (notably, "edit" forms) we just continue on no-effect unconditionally.
Also fix an issue where new, combined or filtered transactions would not be represented properly in the Ajax response (i.e., return final transactions from `applyTransactions()`), and translate some strings.

- 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.

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.

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.

Maniphest Tasks: T2015
Differential Revision: https://secure.phabricator.com/D3861
Summary:
- Clean up a TODO about permanent failures.
- Clean up a TODO about failing tasks after too many retries.
- Clean up a TODO about testing for bad leases.
- Make the lease/retry implementation more flexible and natural.
- Make completely bogus tasks fail permanently.
- Make PhabricatorMetaMTAWorker use new `getWaitBeforeRetry()` (as intended), not hackily implement logic in `getRequiredLeaseTime()`.
- Document worker hooks for failures and retries.
- Provide coverage on everything.
Test Plan: Ran unit tests. Ran `bin/phd debug taskmaster`.

Summary: This simplifies the fairly thorny logic of leasing tasks a bit. I'm planning to introduce another callsite shortly for Drydock.
Test Plan: Ran `bin/phd debug taskmaster`, observed sensible queries and correct operation.

Summary:
When a PhabricatorTestCase dies after creating storage fixtures, it leaves
those storage fixtures around. This doesn't happen often, but when it does
happen it's a pain to cleanup. The --unittest-fixtures option helps automate
that cleanup.
Test Plan:
Ran it with --dryrun, then for real. Became overwhelmed with a Zen like peace
after regarding the tidiness and beauty of SHOW DATABASES.
