[1.0.x] Comment Notify Node Author

Thank you for applying!

Please read Review process for security advisory coverage: What to expect → for more details and Security advisory coverage application checklist → to understand what reviewers look for. Tips for ensuring a smooth review → gives some hints for a smoother review.

The important notes are the following.

• If you have not done it yet, you should run phpcs --standard=Drupal,>DrupalPractice on the project, which alone fixes most of what reviewers would report.
• For the time this application is open, only your commits are allowed.
• The purpose of this application is giving you a new drupal.org role that allows you to opt projects into security advisory coverage, either projects you already created, or projects you will create. The project status will not be changed by this application; no other user will be able to opt projects into security advisory policy.
• We only accept an application per user. If you change your mind about the project to use for this application, or it is necessary to use a different project for the application, please update the issue summary with the link to the correct project and the issue title with the branch to review and the project name.

To the reviewers

Please read How to review security advisory coverage applications → , Application workflow → , What to cover in an application review → , and Tools to use for reviews → .

The important notes are the following.

• It is preferable to wait for a Code Review Administrator before commenting on newly created applications, even to leave a comment similar to the following one. Code Review Administrators will do some preliminary checks that are necessary before any change on the project files is suggested.
• It is also preferable to wait before using a CLI tool → to report what needs to be changed, especially because the comment left from Code Review Administrators suggests to use PHP_CodeSniffer. Before that, manual reviews should be done.
• Reviewers should not copy-paste the output of a CLI tool. They should use a CLI tool only once per application. When they do that, they should later verify the code has been correctly changed; this means, for example, that adding a documentation comment that is not correct just to avoid to get a warning/error is not a correct change that should be reported in a further comment.
• It may be best to have the applicant fix things before further review.

For new reviewers, I would also suggest to first read In which way the issue queue for coverage applications is different from other project queues → .

Fix phpcs issues.

PHPCBF CAN FIX THE 76 MARKED SNIFF VIOLATIONS AUTOMATICALLY
--------------------------------------------------------------------------------

Fixed PHPCS errors and added permissions. Please review it.

Wrong machine name of permission

<strong>administer stop broken link in body</strong>:
  title: 'Administer CNA Configuration'
  description: 'Access to configure CNA settings.'

cna.settings:
  path: "/admin/config/system/cna"
  defaults:
    _form: '\Drupal\cna\Form\CNAConfig'
    _title: "Comment notify node author"
  requirements:
    _permission: "<strong>administer cna configuration</strong>"

Issue permissions.yml file is fixed.

Please review it

• The following points are just a start and don't necessarily encompass all of the changes that may be necessary
• A specific point may just be an example and may apply in other places
• A review is about code that doesn't follow the coding standards, contains possible security issue, or doesn't correctly use the Drupal API; the single points aren't ordered, not even by importance

cna.module

$message['body'][] = t(':message', [':message' => $params['message']]);

That code does not show the translation of $params['message']; it shows it as it is because placeholders in translatable strings are the only part that are not translated. The only way to make the message translatable is to use code similar to the following one.

$message = t("Comment has been updated on %node_title by %username." ['%node_title' => $node_title, '%username' => $username]);

    \Drupal::logger('Comment notify node author')->notice(t('Sent eMail notification for comment with :subject
        to the site administrator eMail address :nodeAuthorEmailAddress', [
          ':nodeAuthorEmailAddress' => $to,
          ':subject' => $subject,
        ]));

The first argument passed to notice() must be a literal string.

/**
 * Implements hook_comment_insert().
 *
 * Responds to insertion of new comment.
 */
function cna_comment_insert(CommentInterface $comment) {

That function is a hook_ENTITY_TYPE_insert() implementation.
There is no need to add a long description to hook implementations.

/**
 * Send mail function.
 *
 * This function handles the process of sending an email message.
 */

The long description is just repeating what the short description already said. The long description is not mandatory, but the parameters and the return value descriptions must be present, if the function has parameters or returns a value.

src/Form/CNAConfig.php

    $this->messenger()
      ->addMessage($this->t('The configuration options have been saved.'));

The parent method already shows a message. It is sufficient to call it.

There are other modules for sending notifications when a node or a comment is created, like the Notify → module. At least the project page should give a list of similar modules and describe the difference with them. (A list of notification modules can be obtained by searching for Notify → .)

I am changing priority as per Issue priorities → .

I am changing priority as per Issue priorities → .

What I reported in my previous comment has not been changed.

Furthermore, the following changes are also necessary.

cna.module

$message = "Comment has been posted on " . $node_title . ", by " . $name . ".";

Everything that is shown in the user interface must be translatable. $message is not translatable, or it would not be a concatenation of strings.

$message['body'][] = t('Link to the comment :linkToComment', [':linkToComment' => $params['url']]);

The correct placeholder for URL starts with :. It must also be wrapped on double quotation marks, as reported on FormattableMarkup::placeholderFormat().

:variable: Return value is escaped with \Drupal\Component\Utility\Html::escape() and filtered for dangerous protocols using UrlHelper::stripDangerousProtocols(). Use this when using the "href" attribute, ensuring the attribute value is always wrapped in quotes

    \Drupal::logger('Comment notify node author')->notice(t('Sent eMail notification for comment with :subject
        to the site administrator eMail address :nodeAuthorEmailAddress', [
          ':nodeAuthorEmailAddress' => $to,
          ':subject' => $subject,
        ]));

The channel ID is normally the module machine name. It is not a message title, nor does it contains spaces.
eMail is misspelled. Either it is email or e-mail.
Placeholders starting with : are used when dangerous protocols needs to be filtered out, which is not the case of $subject. In the case of email addresses, see my previous note.

cna.routing.yml

cna.settings:
  path: "/admin/config/system/cna"
  defaults:
    _form: '\Drupal\cna\Form\CNAConfig'
    _title: "Comment notify node author"
  requirements:
    _permission: "administer cna configuration"

It does not seem the title is correct for a settings form.
