gnutls_handshake() failed GIT Clone [Solution]

2023-07-21T01:41:00.003-07:00

If you are facing error like "curl 56 GnuTLS recv error" while cloning a git repository, it is a "gnutls_handshake()" error.

Error: RPC failed; curl 56 GnuTLS recv error (-24): Decryption has failed

Solution

Rebuilding git with openssl

Follow the steps given below:

1. Install build-essential, fakeroot and dpkg-dev using the following command.

sudo apt-get install build-essential fakeroot dpkg-dev

2. Create a directory named git-rectify in the home folder using the following command.

mkdir ~/git-rectify

3. CD in to the get-rectify directory and get the git source files.

cd ~/git-rectify

apt-get source git

4. Install all the git dependencies.

sudo apt-get build-dep git

5. Install libcurl with all development files.

sudo apt-get install libcurl4-openssl-dev

6. Unpack all the source packages using the following command.

Note: The name “git_2.34.1-1ubuntu1.9” could vary based on the lastest version. So look in to the directory for the correct version name.

dpkg-source -x git_2.34.1-1ubuntu1.9

7. Cd in to “git_2.34.1” folder and open the control file located inside debian folder (git_2.34.1/debian/control) in a text editor. Replace all the occurences of “libcurl4-gnutls-dev” to “libcurl4-openssl-dev”. Also open “debian/rules” file and delete the line “TEST=test”

8. Build the package files using the following command.

sudo dpkg-buildpackage -rfakeroot -b

9. Install the new git package by executing the folling command.

Note: The package name is based on the system architecture. So have a look at the package name located in “git_2.34.1” (could be a different name for you) folder.

sudo dpkg -i git_2.34.1-1ubuntu1.9_amd64.deb

  $query->addWhere($where_last_key, 'node__field_accounts.field_accounts_target_id', 
$account_values['target_id'], 'IN');
}

Method definition
Sql::queueTable($table, $relationship = NULL, JoinPluginBase $join = NULL, $alias = NULL)

To use INNER JOIN

$configuration = [
      'type' => 'INNER',
      'table' => 'user__field_region',
      'field' => 'entity_id',
      'left_table' => 'users_field_data',

How to inject database connection in Drupal 8

2018-05-01T01:22:00.002-07:00

Database connection can be injected in class object using dependency injection.

We can also use service method

\Drupal::database()

This way of using database is suitable for XXX.module file but in class we can use dependency injection.

Using dependency injection :-

Drupal\Core\Database\Connection class for database connection.

use Drupal\Core\Database\Connection;
use Symfony\Component\DependencyInjection\ContainerInterface;

class CustomClass {

  /**
   * The database connection to be used.
   *
   * @var \Drupal\Core\Database\Connection
   */
  protected $database;

  /**
   * @param \Drupal\Core\Database\Connection $database
   *   The database connection to be used.
   */
  public function __construct(Connection $database) {
    $this->database = $database;
  }

  /**
   * {@inheritdoc}
   */
  public static function create(ContainerInterface $container) {
    $container->get('database')
  }

}

$container->get('database') here database is the service.

How to use it

For insert query :-

$query = $this->database->insert('custom_table')
        ->fields(['id', 'message'])
        ->values([1, 'some text']);
$result = $query->execute();

For checking table exists :-

$database_schema = $this->database->schema();
if (!($database_schema->tableExists('custom_table'))) {
  return FALSE;
}

How to call non-static method from static method of same class?

2017-11-18T00:59:00.003-08:00

class Foo {

    public function fun1() {
        echo 'non-static';   
    }

    public static function fun2() {
        echo (new self)->fun1();

Drupal 8.4 requires jQuery 3, which no longer supports load()

2017-10-15T23:49:00.001-07:00

You might get this error

Uncaught TypeError: a.indexOf is not a function
at r.fn.init.r.fn.load (jquery.min.js?v=3.2.1:4)
at Object.attach (scripts.js?v=8.4.0:1)
at Object.Drupal.attachBehaviors (drupal.js?v=8.4.0:25)
at drupal.init.js?v=8.4.0:16
at HTMLDocument.t (ready.min.js?v=1.0.8:4)

Drupal 8.4 is using latest jQuery version 3.2 which does not support load() function.

Instead of using load(), you can use .on(load,function(){})

$(window).on('load', function () {
});

Feeds import - Skip importing item based on some condition

2017-10-12T06:14:00.002-07:00

You can do this using hook_feeds_presave to check the data prior to it being saved.

$item parameter contains the current feed.
Check item on some condition.

To skip an item to being import, use $entity->feeds_item->skip = TRUE;

function mymodule_feeds_presave(FeedsSource $source, $entity, $item) {

  // check that this is fired only for the importer being used
  if($source->importer->id=='my_custom_feeds_importer'){

    if($item['mfgcode'] < '18'){
      $entity->feeds_item->skip = TRUE;
      drupal_set_message(t("Skipping item", 'warning');
    }
  }
}

Create batch process on form submit in Drupal 7

2017-09-28T04:04:00.002-07:00

Using Drupal batch API we can create batch processes.

// form submit.
function product_display_submit($form, &$form_state) {

  $products = $form_state['input']['product_table'];

  if (!empty($products)) {
    // Remove empty values.
    $emptyRemoved = remove_empty($products);
    // re-index array.
    $myarray = array_values($emptyRemoved);


    $progress = 0; // where to start
    $max = count($myarray); // how many records to process until stop.

    // Tell Drupal about the batch process.
    $batch = array(
      'operations' => array(),
      'finished' => 'product_display_batch_finished', // runs after batch is finished
      'title' => t('Deleting products'),
      'init_message' => t('Beginning product delete'),
      'progress_message' => t('Deleted @current out of @total'),
      'error_message' => t('Product deletion failed.'),
    );

    // set batch operation.
    $batch['operations'][] = array('product_display_delete_process', array($progress, $max, $myarray));
    batch_set($batch);
  }

}

function product_display_delete_process($progress, $max, $products, &$context) {

  for ($i=$progress; $i < $max; $i++) {
    // Update our progress information.
    $context['message'] = t('Now processing product id #%product_id', array('%product_id' => $products[$i]));

      // $result = commerce_product_delete_multiple($products);
      $result = commerce_product_delete($products[$i]);

      // Delete product display.
      $query = new EntityFieldQuery;

      $query->entityCondition('entity_type', 'node', '=')
      ->propertyCondition('type', 'product_display')
      ->fieldCondition('field_product', 'product_id', $products[$i], '=')
      ->range(0, 1);
      $result = $query->execute();

      if (!empty($result['node'])) {
        // Delete Product Display node.
        foreach ($result['node'] as $nid => $val) break;
        try {
          node_delete($nid);

          // Delete alias.
          $path = path_load(

          );

          path_delete($path['pid']);
        }
        catch (Exception $e) {
          drupal_set_message('Error occurred. Check logs.');
        }
      }
  }

}

function product_display_batch_finished($success, $results, $operations) {
  if ($success) {
    drupal_set_message('Product deletion is complete');
  }
  else {
    $error_operation = reset($operations);
    watchdog('products_batchprocess_error',t('An error occurred while processing @operation with arguments : @args', array('@operation' => $error_operation[0], '@args' => print_r($error_operation[0], TRUE))));

Mapping of XML feeds conditionally using Feed Importer In Drupal 7

2017-09-06T00:10:00.005-07:00

Map XML feeds on some basic conditions without using feeds tamper module

First, take a look at an example

<images>
<image type="file">https://s3.amazon.com/example1.pdf</image>
<image type="file">https://s3.amazon.com/example3.pdf</image>
<image type="file">https://s3.amazon.com/example2.pdf</image>
<image type="image">https://s3.amazon.com/example.jpg</image>
</images>

Case 1: If you want to import only those feeds that has type "image" then your XML Parser settings should be like Images/Image[./@type = 'image']

Case 2: Import feeds that has not file type then Images/Image[./@type != 'file']

Example 2:
