//=========================================================================
// 1. DATABASE SETUP
//=========================================================================
// First, you need to configure the database where all Moodle data //
// will be stored. This database must already have been created //
// and a username/password created to access it. //
$CFG->dbtype = 'pgsql'; // 'pgsql', 'mariadb', 'mysqli', 'sqlsrv' or 'oci'
$CFG->dblibrary = 'native'; // 'native' only at the moment
$CFG->dbhost = 'localhost'; // eg 'localhost' or 'db.isp.com' or IP
$CFG->dbname = 'moodle'; // database name, eg moodle
$CFG->dbuser = 'username'; // your database username
$CFG->dbpass = 'password'; // your database password
$CFG->prefix = 'mdl_'; // prefix to use for all table names
$CFG->dboptions = array(
'dbpersist' => false, // should persistent database connections be
// used? set to 'false' for the most stable
// setting, 'true' can improve performance
// sometimes
'dbsocket' => false, // should connection via UNIX socket be used?
// if you set it to 'true' or custom path
// here set dbhost to 'localhost',
// (please note mysql is always using socket
// if dbhost is 'localhost' - if you need
// local port connection use '127.0.0.1')
'dbport' => '', // the TCP port number to use when connecting
// to the server. keep empty string for the
// default port
'dbhandlesoptions' => false,// On PostgreSQL poolers like pgbouncer don't
// support advanced options on connection.
// If you set those in the database then
// the advanced settings will not be sent.
'dbcollation' => 'utf8mb4_unicode_ci', // MySQL has partial and full UTF-8
// support. If you wish to use partial UTF-8
// (three bytes) then set this option to
// 'utf8_unicode_ci', otherwise this option
// can be removed for MySQL (by default it will
// use 'utf8mb4_unicode_ci'. This option should
// be removed for all other databases.
// 'fetchbuffersize' => 100000, // On PostgreSQL, this option sets a limit
// on the number of rows that are fetched into
// memory when doing a large recordset query
// (e.g. search indexing). Default is 100000.
// Uncomment and set to a value to change it,
// or zero to turn off the limit. You need to
// set to zero if you are using pg_bouncer in
// 'transaction' mode (it is fine in 'session'
// mode).
/*
'connecttimeout' => null, // Set connect timeout in seconds. Not all drivers support it.
'readonly' => [ // Set to read-only slave details, to get safe reads
// from there instead of the master node. Optional.
// Currently supported by pgsql and mysqli variety classes.
// If not supported silently ignored.
'instance' => [ // Readonly slave connection parameters
[
'dbhost' => 'slave.dbhost',
'dbport' => '', // Defaults to master port
'dbuser' => '', // Defaults to master user
'dbpass' => '', // Defaults to master password
],
[...],
],
Instance(s) can alternatively be specified as:
'instance' => 'slave.dbhost',
'instance' => ['slave.dbhost1', 'slave.dbhost2'],
'instance' => ['dbhost' => 'slave.dbhost', 'dbport' => '', 'dbuser' => '', 'dbpass' => ''],
'connecttimeout' => 2, // Set read-only slave connect timeout in seconds. See above.
'latency' => 0.5, // Set read-only slave sync latency in seconds.
// When 'latency' seconds have lapsed after an update to a table
// it is deemed safe to use readonly slave for reading from the table.
// It is optional. If omitted once written to a table it will always
// use master handle for reading.
// Lower values increase the performance, but setting it too low means
// missing the master-slave sync.
'exclude_tables' => [ // Tables to exclude from read-only slave feature.
'table1', // Should not be used, unless in rare cases when some area of the system
'table2', // is malfunctioning and you still want to use readonly feature.
], // Then one can exclude offending tables while investigating.
More info available in lib/dml/moodle_read_slave_trait.php where the feature is implemented.
]

// For all database config settings see https://docs.moodle.org/en/Database_settings
);
//=========================================================================
// 2. WEB SITE LOCATION
//=========================================================================
// Now you need to tell Moodle where it is located. Specify the full
// web address to where moodle has been installed. If your web site
// is accessible via multiple URLs then choose the most natural one
// that your students would use. Do not include a trailing slash
//
// If you need both intranet and Internet access please read
// http://docs.moodle.org/en/masquerading
$CFG->wwwroot = 'http://example.com/moodle';
//=========================================================================
// 3. DATA FILES LOCATION
//=========================================================================
// Now you need a place where Moodle can save uploaded files. This
// directory should be readable AND WRITEABLE by the web server user
// (usually 'nobody' or 'apache'), but it should not be accessible
// directly via the web.
//
// - On hosting systems you might need to make sure that your "group" has
// no permissions at all, but that "others" have full permissions.
//
// - On Windows systems you might specify something like 'c:\moodledata'
$CFG->dataroot = '/home/example/moodledata';
//=========================================================================
// 4. DATA FILES PERMISSIONS
//=========================================================================
// The following parameter sets the permissions of new directories
// created by Moodle within the data directory. The format is in
// octal format (as used by the Unix utility chmod, for example).
// The default is usually OK, but you may want to change it to 0750
// if you are concerned about world-access to the files (you will need
// to make sure the web server process (eg Apache) can access the files.
// NOTE: the prefixed 0 is important, and don't use quotes.
$CFG->directorypermissions = 02777;
//=========================================================================
// 5. DIRECTORY LOCATION (most people can just ignore this setting)
//=========================================================================
// A very few webhosts use /admin as a special URL for you to access a
// control panel or something. Unfortunately this conflicts with the
// standard location for the Moodle admin pages. You can work around this
// by renaming the admin directory in your installation, and putting that
// new name here. eg "moodleadmin". This should fix all admin links in Moodle.
// After any change you need to visit your new admin directory
// and purge all caches.
$CFG->admin = 'admin';
//=========================================================================
// 6. OTHER MISCELLANEOUS SETTINGS (ignore these for new installations)
//=========================================================================
//
// These are additional tweaks for which no GUI exists in Moodle yet.
//

// 8. FORCED SETTINGS
//=========================================================================
// It is possible to specify normal admin settings here, the point is that
// they can not be changed through the standard admin settings pages any more.
//
// Core settings are specified directly via assignment to $CFG variable.
// Example:
// $CFG->somecoresetting = 'value';
//
// Plugin settings have to be put into a special array.
// Example:
// $CFG->forced_plugin_settings = array('pluginname' => array('settingname' => 'value', 'secondsetting' => 'othervalue'),
// 'otherplugin' => array('mysetting' => 'myvalue', 'thesetting' => 'thevalue'));
// Module default settings with advanced/locked checkboxes can be set too. To do this, add
// an extra config with '_adv' or '_locked' as a suffix and set the value to true or false.
// Example:
// $CFG->forced_plugin_settings = array('pluginname' => array('settingname' => 'value', 'settingname_locked' => true, 'settingname_adv' => true));
//
//=========================================================================
// 9. PHPUNIT SUPPORT
//=========================================================================
// $CFG->phpunit_prefix = 'phpu_';
// $CFG->phpunit_dataroot = '/home/example/phpu_moodledata';
// $CFG->phpunit_directorypermissions = 02777; // optional
// $CFG->phpunit_profilingenabled = true; // optional to profile PHPUnit runs.
//
//
//=========================================================================
// 10. SECRET PASSWORD SALT
//=========================================================================
// A site-wide password salt is no longer used in new installations.
// If upgrading from 2.6 or older, keep all existing salts in config.php file.
//
// $CFG->passwordsaltmain = 'a_very_long_random_string_of_characters#@6&*1';
//
// You may also have some alternative salts to allow migration from previously
// used salts.
//
// $CFG->passwordsaltalt1 = '';
// $CFG->passwordsaltalt2 = '';
// $CFG->passwordsaltalt3 = '';
// ....
// $CFG->passwordsaltalt19 = '';
// $CFG->passwordsaltalt20 = '';
//
//
//=========================================================================
// 11. BEHAT SUPPORT
//=========================================================================
// Behat test site needs a unique www root, data directory and database prefix:
//
// $CFG->behat_wwwroot = 'http://127.0.0.1/moodle';
// $CFG->behat_prefix = 'bht_';
// $CFG->behat_dataroot = '/home/example/bht_moodledata';
//
// You can override default Moodle configuration for Behat and add your own
// params; here you can add more profiles, use different Mink drivers than Selenium...
// These params would be merged with the default Moodle behat.yml, giving priority
// to the ones specified here. The array format is YAML, following the Behat
// params hierarchy. More info: http://docs.behat.org/guides/7.config.html
// Example:
// $CFG->behat_config = array(
// 'Mac-Firefox' => array(
// 'suites' => array (
// 'default' => array(
// 'filters' => array(
// 'tags' => '~@_file_upload'
// ),
// ),
// ),
// 'extensions' => array(
// 'Behat\MinkExtension' => array(
// 'selenium2' => array(
// 'browser' => 'firefox',
// 'capabilities' => array(
// 'platform' => 'OS X 10.6',
// 'version' => 20
// )
// )
// )
// )
// ),
// 'Mac-Safari' => array(
// 'extensions' => array(
// 'Behat\MinkExtension' => array(
// 'selenium2' => array(
// 'browser' => 'safari',
// 'capabilities' => array(
// 'platform' => 'OS X 10.8',
// 'version' => 6
// )
// )
// )
// )
// )
// );
// You can also use the following config to override default Moodle configuration for Behat.
// This config is limited to default suite and will be supported in later versions.
// It will have precedence over $CFG->behat_config.
// $CFG->behat_profiles = array(
// 'phantomjs' => array(
// 'browser' => 'phantomjs',
// 'tags' => '~@_file_upload&&~@_alert&&~@_bug_phantomjs',
// 'wd_host' => 'http://127.0.0.1:4443/wd/hub',
// 'capabilities' => array(
// 'platform' => 'Linux',
// 'version' => 2.1
// )
// ),
// );
//
// All this page's extra Moodle settings are compared against a white list of allowed settings
// (the basic and behat_* ones) to avoid problems with production environments. This setting can be
// used to expand the default white list with an array of extra settings.
// Example:
// $CFG->behat_extraallowedsettings = array('somecoresetting', ...);
//
// You should explicitly allow the usage of the deprecated behat steps, otherwise an exception will
// be thrown when using them. The setting is disabled by default.
// Example:
// $CFG->behat_usedeprecated = true;
//
// If you are using a slow machine, it may help to increase the timeouts that Behat uses. The
// following example will increase timeouts by a factor of 3 (using 30 seconds instead of 10
// seconds, for instance).
// Example:
// $CFG->behat_increasetimeout = 3;
//
// Including feature files from directories outside the dirroot is possible if required. The setting
// requires that the running user has executable permissions on all parent directories in the paths.
// Example:
// $CFG->behat_additionalfeatures = array('/home/developer/code/wipfeatures');
//
// You can make behat save several dumps when a scenario fails. The dumps currently saved are:
// * a dump of the DOM in it's state at the time of failure; and
// * a screenshot (JavaScript is required for the screenshot functionality, so not all browsers support this option)
// Example:
// $CFG->behat_faildump_path = '/my/path/to/save/failure/dumps';
//
// You can make behat pause upon failure to help you diagnose and debug problems with your tests.
//
// $CFG->behat_pause_on_fail = true;
//
// You can specify db, selenium wd_host etc. for behat parallel run by setting following variable.
// Example:
// $CFG->behat_parallel_run = array (
// array (
// 'dbtype' => 'mysqli',
// 'dblibrary' => 'native',
// 'dbhost' => 'localhost',
// 'dbname' => 'moodletest',
// 'dbuser' => 'moodle',
// 'dbpass' => 'moodle',
// 'behat_prefix' => 'mdl_',
// 'wd_host' => 'http://127.0.0.1:4444/wd/hub',
// 'behat_wwwroot' => 'http://127.0.0.1/moodle',
// 'behat_dataroot' => '/home/example/bht_moodledata'
// ),
// );
//
// To change name of behat parallel run site, define BEHAT_PARALLEL_SITE_NAME and parallel run sites will be suffixed
// with this value
// Example:
// define('BEHAT_PARALLEL_SITE_NAME', 'behatparallelsite');
//
// Command line output for parallel behat install is limited to 80 chars, if you are installing more then 4 sites and
// want to expand output to more then 80 chars, then define BEHAT_MAX_CMD_LINE_OUTPUT
// Example:
// define('BEHAT_MAX_CMD_LINE_OUTPUT', 120);
//
// Behat feature files will be distributed randomly between the processes by default. If you have timing file or want
// to create timing file then define BEHAT_FEATURE_TIMING_FILE with path to timing file. It will be updated for each
// run with latest time taken to execute feature.
// Example:
// define('BEHAT_FEATURE_TIMING_FILE', '/PATH_TO_TIMING_FILE/timing.json');
//
// If you don't have timing file and want some stable distribution of features, then you can use step counts to
