'user.default-profile-image-phid' => 'PHID-FILE-f57aaefce707fc4060ef',
// -- Access Control -------------------------------------------------------- //
// Phabricator users have one of three access levels: "anyone", "verified",
// or "admin". "anyone" means every user, including users who do not have
// accounts or are not logged into the system. "verified" is users who have
// accounts, are logged in, and have satisfied whatever verification steps
// the configuration requires (e.g., email verification and/or manual
// approval). "admin" is verified users with the "administrator" flag set.
// These configuration options control which access level is required to read
// data from Phabricator (e.g., view revisions and comments in Differential)
// and write data to Phabricator (e.g., upload files and create diffs). By
// default they are both set to "verified", meaning only verified user
// accounts can interact with the system in any meaningful way.
// If you are configuring an install for an open source project, you may
// want to reduce the "phabricator.read-access" requirement to "anyone". This
// will allow anyone to browse Phabricator content, even without logging in.
// Alternatively, you could raise the "phabricator.write-access" requirement
// to "admin", effectively creating a read-only install.
// Controls the minimum access level required to read data from Phabricator
// (e.g., view revisions in Differential). Allowed values are "anyone",
// "verified", or "admin". Note that "anyone" includes users who are not
// logged in! You should leave this at 'verified' unless you want your data
// to be publicly readable (e.g., you are developing open source software).
'phabricator.read-access' => 'verified',
// Controls the minimum access level required to write data to Phabricator
// (e.g., create new revisions in Differential). Allowed values are
// "verified" or "admin". Setting this to "admin" will effectively create a
// read-only install.

// Phabricator. You can leave it disabled unless you're developing against
// Phabricator.
// Determines whether or not DarkConsole is available. DarkConsole exposes
// some data like queries and stack traces, so you should be careful about
// turning it on in production (although users can not normally see it, even
// if the deployment configuration enables it).
'darkconsole.enabled' => true,
// Always enable DarkConsole, even for logged out users. This potentially
// exposes sensitive information to users, so make sure untrusted users can
// not access an install running in this mode. You should definitely leave
// this off in production. It is only really useful for using DarkConsole
// utilties to debug or profile logged-out pages. You must set
// 'darkconsole.enabled' to use this option.
'darkconsole.always-on' => false,
// Allows you to mask certain configuration values from appearing in the
// "Config" tab of DarkConsole.

// The password to use when connecting to MySQL.
'mysql.pass' => '',
// The MySQL server to connect to.
'mysql.host' => 'localhost',
// -- Email ----------------------------------------------------------------- //
// Some Phabricator tools send email notifications, e.g. when Differential
// revisions are updated or Maniphest tasks are changed. These options allow
// you to configure how email is delivered.
// You can test your mail setup by going to "MetaMTA" in the web interface,
// clicking "Send New Message", and then composing a message.
// Default address to send mail "From".
'metamta.default-address' => 'noreply@example.com',
// When a user takes an action which generates an email notification (like
// commenting on a Differential revision), Phabricator can either send that
// mail "From" the user's email address (like "alincoln@logcabin.com") or
// "From" the 'metamta.default-address' address. The user experience is
// generally better if Phabricator uses the user's real address as the "From"
// since the messages are easier to organize when they appear in mail clients,
// but this will only work if the server is authorized to send email on behalf
// of the "From" domain. Practically, this means:
// - If you are doing an install for Example Corp and all the users will
// have corporate @corp.example.com addresses and any hosts Phabricator
// is running on are authorized to send email from corp.example.com,
// you can enable this to make the user experience a little better.
// - If you are doing an install for an open source project and your
// users will be registering via Facebook and using personal email
// addresses, you MUST NOT enable this or virtually all of your outgoing
// email will vanish into SFP blackholes.
// - If your install is anything else, you're much safer leaving this
// off since the risk in turning it on is that your outgoing mail will
// mostly never arrive.
'metamta.can-send-as-user' => false,
// Adapter class to use to transmit mail to the MTA. The default uses
// PHPMailerLite, which will invoke PHP's mail() function. This is appropriate
// if mail() actually works on your host, but if you haven't configured mail
// it may not be so great. You can also use Amazon SES, by changing this to
// 'PhabricatorMailImplementationAmazonSESAdapter', signing up for SES, and
// filling in your 'amazon-ses.access-key' and 'amazon-ses.secret-key' below.
'metamta.mail-adapter' =>
'PhabricatorMailImplementationPHPMailerLiteAdapter',
// When email is sent, try to hand it off to the MTA immediately. This may
// be worth disabling if your MTA infrastructure is slow or unreliable. If you
// disable this option, you must run the 'metamta_mta.php' daemon or mail
// won't be handed off to the MTA. If you're using Amazon SES it can be a
// little slugish sometimes so it may be worth disabling this and moving to
// the daemon after you've got your install up and running. If you have a
// properly configured local MTA it should not be necessary to disable this.
'metamta.send-immediately' => true,
// If you're using Amazon SES to send email, provide your AWS access key
// and AWS secret key here. To set up Amazon SES with Phabricator, you need
// to:
// - Make sure 'metamta.mail-adapter' is set to:
// "PhabricatorMailImplementationAmazonSESAdapter"
// - Make sure 'metamta.can-send-as-user' is false.
// - Make sure 'metamta.default-address' is configured to something sensible.
// - Make sure 'metamta.default-address' is a validated SES "From" address.

// This is hashed with other inputs to generate CSRF tokens. If you want, you
// can change it to some other string which is unique to your install. This
// will make your install more secure in a vague, mostly theoretical way. But
// it will take you like 3 seconds of mashing on your keyboard to set it up so
// you might as well.
