Read configuration from the new database source.
This adds an extra MySQL connect + query to every page. They're very cheap so I think we can suffer them for now, but I'd like to put cache in front of this at some point. The difficulties are:
- If we use APC, multi-frontend installs (Facebook) can't dirty it (major problem), and the CLI can't dirty it (fine for now, maybe a major problem later).
- If we use Memcache, we need to add config stuff.
- We could use APC in all non-Facebook installs if we can make it dirtyable from the CLI, but I don't see a reasonable way to do that.
- We don't have any other caches which are faster than the database.
So I'll probably implement Memcache support at some point, although this is a lame excuse for it.

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.)

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.

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`.

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.

- 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.

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.

Test Plan: Built a proxied DialogResponse on top of this.
