Docker

SSH into docker-compose container
# as default user
# here php is container name
docker-compose -f docker-compose.yml exec -e php /bin/sh

# as root
docker-compose -f docker-compose.yml -f docker-compose.osx.yml exec -e XDEBUG_MODE=off -u root php /bin/sh


Drupal

Log Exception Error
$e = new Exception();
$variables = Error::decodeException($e);
\Drupal::logger('channel')->error('%type: @message in %function (line %line of %file) @backtrace_string.', $error + ['backtrace' => $backtrace]);
Kill Static Page Cache
  • \Drupal::service('page_cache_kill_switch')->trigger();
  • OR no_cache in routing.yml
settings.local.php
  • Prevent caching of classes $settings['class_loader_auto_detect'] = FALSE;
Drupal.org Contrib
  • Patch file naming [project_name]-[short-description]-[issue-number]-[comment-number].patch
phpcbf

../vendor/bin/phpcbf -n --standard="../vendor/drupal/coder/coder_sniffer/Drupal" modules/custom/custom_module_name/

Twig Tricks
  • Add this to twig template if not rendering {{ content }}. This properly adds/invalidates cache tags. {% set catch_cache = content|render %}
Priority
  • Higher comes first. 100 starts before 0


Theme

  • Theme a form

    This Requires a hook_theme().

    return [
  'form_id' => [
    'render element' => form
  ]
]

Custom Solr Functions

Drupal: hook_search_api_solr_query_alter()

// If the date is in the future, give the score a diminshing boost.
$solr_field_names = $query->getIndex()->getServerInstance()->getBackend()->getSolrFieldNames($query->getIndex());
$boost_functions = [];
if ($solr_field_names['future_only_date']) {
  $boost_functions[] = 'if(min(0,sub(ms(NOW/HOUR),ms(' . $solr_field_names['future_only_date'] . '))),recip(ms(' . $solr_field_names['future_only_date'] . ',NOW/HOUR),3.16e-11,3,.9),0)^2';
}

// Boost content_type_to_match Content based on the published date.
// The closer the date is to the current date, the higher the boost.
if ($solr_field_names['published_date']) {
  $boost_functions[] = 'if(eq(' . $solr_field_names['type'] .',\'content_type_to_match\'),recip(abs(ms(' . $solr_field_names['published_date'] . ',NOW/HOUR)),3.16e-11,3,.9),0)^2';
}

// Apply all the boost functions.
if ($boost_functions) {
  $boost_functions = implode(' ', $boost_functions);
  $solarium_query->getEDisMax()->setBoostFunctions($boost_functions);
  $solarium_query->addParam('defType', 'edismax');
}

    return null;
}

    pipelineCount = Ci::Pipeline.where(project: project).where("created_at > ?", 1.year.ago).count()
    if pipelineCount > 0
      csv << [project.id, "#{project.namespace.name.to_s}/#{project.name.to_s}", "#{pipelineCount}"]
      puts "id #{project.id}: #{project.namespace.name.to_s}/#{project.name.to_s} pipelines: #{pipelineCount}"
    end
  end
end

SQL

  • Show sql tables by size

    SELECT (data_length+index_length)/power(1024,2) tablesize_mb, table_name 
FROM information_schema.tables 
WHERE table_schema='db_name' order by tablesize_mb;

  • Show Sql Import status

    pv sqlfile.sql | mysql -u user -p dbname

  • sql import error Unknown collation: 'utf8mb4_0900_ai_ci'

    # For mac.
sed -i '' 's/utf8mb4_0900_ai_ci/utf8mb4_unicode_ci/g' 2019-10-26-prod.sql

# For linux.
sed -e 's/utf8mb4_0900_ai_ci/utf8mb4_unicode_ci/g' -i myfilename.sql

    Solution from this github issue
    This usually happens when importing from mysql 8

  • sql import error @@GLOBAL.GTID_PURGED can only be set when @@GLOBAL.GTID_EXECUTED is empty

    ../vendor/bin/drush sql-dump --extra-dump=--set-gtid-purged=OFF | gzip > /tmp/db-backup.sql.gz

    Solution from this stackoverflow issue

  • sql give SUPER priveleges to a user

    grant super on *.* to 'my_user'@'localhost';
revoke super on *.* from 'my_user'@'localhost';

  • search within sql file

    sed -n -e 123456p your-file.sql
sed -n 123455,123457p your-file.sql


Notes to self

  • When creating a custom views filter, make sure you create a schema file to map the schema settings. (e.g. config/schema/module.views.schema.yml)


XDebug

(Version 3 only)

  • Debugging Command Line (with PHPSTORM)

    • (preferred) run these EXPORT commands each time you need it. 
      export XDEBUG_CONFIG="idekey=PHPSTORM mode=debug start_with_request=trigger remote_port=9000"
export PHP_IDE_CONFIG="serverName=nameOfYourServerInPhpStorm"
    • OR Set cli php.ini 
      [XDebug]
zend_extension="/usr/lib/php/7.4/modules/xdebug-2.9.5.so"

xdebug.mode=develop,debug
xdebug.client_host=10.0.2.2
xdebug.client_port=9000
xdebug.idekey=PHPSTORM

  • Debugging Browser Requests

    xdebug.mode=develop,debug
xdebug.client_host=10.0.2.2
xdebug.client_port=9000
xdebug.start_with_request=yes
xdebug.idekey = PHPSTORM

  • Cannot accept external Xdebug connection: Cannot evaluate expression 'isset($_SERVER['PHP_IDE_CONFIG'])'
    Add /usr/lib/php/sessionclean to the session_config line. e.g.
    /usr/lib/php/sessionclean

    session_config=$(PHP_INI_SCAN_DIR=/etc/php/${version}/${conf_dir}/conf.d/ php${version} -c /etc/php/${version}/${conf_dir}/php.ini -d "xdebug.remote_autostart=0" -d "error_reporting='~E_ALL'" -r 'foreach(ini_get_all("session") as $k => $v) echo "$k=".$v["local_value"]."\n";')
