8 – How do I display a field of parent memory in my module?

I own a Drupal 8.7 site with the Drupal Commerce 2.14 module.

I have created a marketplace (several merchants on the same site). In the business type, I created a field "Text (formatted, long)" with the computer name field_terms_and_conditions,

In this field, the trader specifies his general conditions of sale, which the customer must accept during the ordering process.

If the customer orders in multiple stores, multiple shopping carts are created (the name of the store is displayed above each cart). It works very well. Now that Drupal Commerce manages the address book, orders are very fast.

At the moment I have created a view that shows the content of the field field_terms_and_conditions on one side. I've also created a custom module to display a checkbox with a link to the general sales conditions in a modal window.

I want to render the field directly field_terms_and_conditions in the modal window without using a view. How do you do that ?

/src/Plugin/Commerce/CheckoutPane/MarketplaceTermsAndConditions.php :

order->getStore()->getName();
    $store_id = $this->order->getStoreId();
    $pane_form('#attached')('library')() = 'core/drupal.dialog.ajax';
    $attributes = (
      'attributes' => (
        'class' => 'use-ajax',
        'data-dialog-type' => 'modal',
        'data-dialog-options' => Json::encode((
          'width' => 'auto'
        )),
      ),
    );
    $link = Link::fromTextAndUrl(
      $this->t('terms and conditions of the store "@store_name"', ('@store_name' => $store_name)),
      Url::fromUri("internal:/store/$store_id/cgv", $attributes)
    )->toString();
    $pane_form('marketplace_terms_and_conditions') = (
      '#type' => 'checkbox',
      '#default_value' => FALSE,
      '#title' => $this->t('I have read and accept @terms.', ('@terms' => $link)),
      '#required' => TRUE,
      '#weight' => $this->getWeight(),
    );
    return $pane_form;
  }

}

TWRP memory for decrypting passwords – Android Enthusiasts Stack Exchange

This TWRP requires a password because of your /data is encrypted, which is pre-set since Android 6.

To permanently decrypt the file system, you must format /data and flashing a "disable Force Encryption" package. Note this formatting /data deletes all your files, including photos, music, etc. in your internal memory,

Also, be careful when flashing other ROMs or using OTAs /data re-encrypted and you need to reformat it again. You must update the Force Encryption Disabler each time you update another ROM / OTA.

Applications – Recover WhatsApp data from internal memory when moving to a new phone

I installed WhatsApp on my old phone.
WhatsApp is backed up to both Google Drive and local storage.
Google Drive backup is for text chat and pictures only (default).
The local backup contains everything (audio, video, documents, etc.).

I want to transfer all my WhatsApp data to my new phone.
Usually it is done like this:

  1. Copy all WhatsApp folder files from the old phone to the new phone.
  2. Install WhatsApp on the new phone.
  3. Start WhatsApp on the new phone and click Restore when prompted to restore data.

The problem

Restoring WhatsApp restores information from Google Drive, not from local storage.

How to force WhatsApp to recover all data from local storage?

Memory Task Usability Test – User Experience Stack Exchange

What is the scenario in which a task in a usability test is designed to assess participants' memory of the content of a page?

I recently ran a user test asking participants to pull content from a page, but I do not understand what you can learn from it if the content is really small or just a few links on the page.

Conceptually Understand Memory Mapping – Computer Science Stack Exchange

I've read several blogs and stack exchange questions, but I can not understand the real drawbacks of memory allocation files. I see that the following are frequently listed:

  1. You can not save large files (> 4 GB) with a 32-bit address space.

QUESTION 1:
Why? Is not that the whole point of the virtual memory? If a file is larger than 4 GB, it may lead to the Recycle Bin by swapping some pages associated with memory. Why is there a restriction?

  1. If the application tries to read from a portion of the file that is not loaded in the page cache, this will (the application) result in a page fault penalty, which in turn means increased I / O latency for the operation ,

QUESTION 2:
Is not this also the case for a standard file I / O operation? When an application attempts to read from a portion of a file that has not yet been cached, this results in a system call in which the kernel loads the appropriate page or block from the device. In addition, the page must be copied back to the user space buffer.

Here's the worry that page faults are more expensive in some way than system calls in general – my interpretation of what Linus Torvalds says here? Is it because of blocking page faults => the thread is not being scheduled by the CPU => wasting valuable time? Or am I missing something here?

  1. Overhead of kernel mappings and data structures – according to Linus Torvalds. I will not even try to question that premise, as I do not know much about the internals of the Linux kernel. 🙂

  2. No support for asynchronous I / O for memory allocation files.

QUESTION 3:
Is there any architectural limitation in supporting asynchronous I / O for memory allocation files, or is it just that nobody has come to do so?

QUESTION 4:
Vagely related, but my interpretation of this article is that the kernel can do standard I / O reads, but not files with memory mappings (unless recommended with madvice ()). Is that exactly?
