Drupal 7 image optimization

Call us today at Drupal 7 provides a file field that allows for uploading files and images to your Nodes but it is limited in functionality. The core file field only allows for uploading one file at a time and does not permit drag and drop functionality. However, with a few modules and a little bit of configuration we can easily provide this functionality to your site. Now that the modules are installed and enable we need setup the new upload widget on your content type s :.

Drupal website image optimization as one of recipes for good speed

This page is used to keep track of common platform considerations, derived from Pantheon's distributed nature. Check back often, as we are keeping it current as we make improvements to address these limitations. Pantheon does not provide access to a shell environment over SSH. To take full advantage of Pantheon, you should load your public SSH key into your account.

SSH keys are a best practice for authentication, allowing you more security than a simple password. You will only need to do this once, no matter how many sites you work on. If you are prompted for a password when connecting to the platform, use your Pantheon Dashboard login password to gain access. Larger agencies with multiple developers using password authentication to login may see access issues across the organization.

To avoid potential authentication failures, we strongly recommend using SSH keys. In an effort to focus internal development and engineering work, the Pantheon Dashboard supports the following browsers:. The max execution time for PHP scripts on the platform is seconds.

Batch uploads, like one might see importing products with WooCommerce can encounter this limit. In this or similar instances, consider performing larger operations locally, then importing the code, files, and database back up to the platform.

In Test and Live environments on plans with multiple application containers, it is difficult to batch export data to a file. Many contrib plugins and modules are not designed to support multiple application containers. It might be possible to get data export working, but that may require additional effort and custom code. Often, modules and plugins do this type of batch export by continuously appending data to the same file in each request in the batch process.

With multiple application containers, the result is that several containers will attempt to add data to the same file at once, while simultaneously syncing their own version of the updated file to other appservers and receiving updates from other application containers.

The exported data will likely be incomplete. A non-batched export of a dataset small enough to complete within the set timeout for web requests will likely work. Have each request in the data export write to its own tmp file, then concatenate these at the end. This solution requires that the Persistent Temporary Path Workaround is in place. Do small batches and add enough time between each request in the batch process to allow the updated file to be synced between all application containers.

Larger data sets can be exported, as command line processes have longer timeouts than HTTP requests. For more details, see Timeouts on Pantheon. The export won't need to be batched and can therefore run to completion on a single application container. Often, the best solution is to implement data exports as a web service, incrementally exchanging the data with the target system.

MySQL stored procedures are not supported. Due to the nature of the platform, there is no guarantee that they will persist following a database migration. You can avoid the use of stored procedures by using parameterized queries or object-relational mapping. As an alternative, you may consider Cron for WordPress or Drupal. The Pantheon platform includes Drupal Steward , a platform-level mitigation of certain highly-critical vulnerabilities that are identified in Drupal core, as a feature for all Drupal sites on Pantheon.

All Pantheon sites are protected by Drupal Steward. Because of the cloud-based nature of Pantheon's infrastructure, we cannot ensure the high deliverability of emails originating from your Application Containers, as they have no fixed location.

While all sites have access to a local Postfix service for testing and development, we recommend using an external SMTP gateway for example SendGrid in production to ensure that your email is delivered.

We do not support ffmpeg transcoding, and we do not have plans to add this feature. However, it is possible to run a site on the platform and integrate with a third-party transcoding service or multimedia platform that lets you create streaming-optimized videos. Those providers have optimized the highly complex process of transcoding and serving video content, and leveraging their infrastructure is often preferable to a custom solution.

Emoji support is available out of the box on WordPress and Drupal 8. Drupal 7 sites can enable Emoji support by following this procedure:. Clear Drush cache using Terminus :. Start by making a backup of the site database, then place the site in maintenance mode and run the following:. This will convert the database tables in the existing installation to the proper encoding to support emoji characters.

After making the conversion, test it out by placing an emoji in the site text. The platform is only optimized for Drupal or WordPress and no others. Although PHP will run, we can not assist you in getting the non-approved frameworks running in any way. If you have individual directories with tens of thousands of files e.

The danger zone begins at around 50, files in a single directory, and performance drops off suddenly at over , files. Drupal itself is capable of managing uploaded content into different directories based on the date or user, which is preferable to dumping all uploads into a single place. Refactoring an existing large-scale site with this issue is usually simply a matter of re-arranging the files and then updating the files table in Drupal.

Consider the File field Paths module to help resolve issues with highly populated directories. Pantheon sites use nginx to concurrently serve requests. The nginx web server ignores distributed configuration files such as. This configuration is standard across all Pantheon sites, and modifications to the nginx.

If your site contains rules in. Drupal 7 and 8 checks for arbitrary code execution prevention by looking for a specific string in the. For more details, see this Drupal. HTTP range requests enable sending only a portion of an HTTP message from server to client, and are typically used to speed viewing of large media like PDFs, video background images, or streaming content like podcasts and videos with pause and resume functions.

Byte-range request header parameters are not supported on Pantheon. Modules and plugins that require specified byte-ranges will not work. At this time, they are not supported.

For more information see Modules with Known Issues. Sandbox sites that are over four months old that have not had code commits or other Git activity for three months are "frozen". All requests to a frozen site will return a Site Frozen error code, and the site's Dashboard will be unavailable.

You can easily reactivate a site by visiting your Pantheon User Dashboard, select the frozen site in the Dashboard, then click Unfreeze site. Within a few minutes, the site will be ready for development again. If you experience any issues, like missing static assets, a backup of the site is available and can be restored via the Site Dashboard.

Please note that only files that have been committed will be available after unfreezing. IP-based security is not recommended on Pantheon - or any cloud platform because the actual IP address where code executes from can change as application containers are migrated throughout the infrastructure. When a code repo is larger than 2GB, it increases the possibility of Git errors when committing code on Pantheon.

We suggest keeping multimedia assets out of the repo by moving them to a media file storage service such as Amazon S3 , and using version control to track URLs. If your repository has grown over 2GB and is causing problems such as errors when cloning , consider pruning and optimizing the repo.

Due to the configuration of the Pantheon Filesystem , Pantheon's file serving infrastructure is not optimized to store and deliver very large files. Files over MB will fail no matter how they are uploaded. Transfers with files over 50MB will experience noticeable degradation in performance. If you are distributing large binaries or hosting big media files, we recommend using a CDN like Amazon S3 as a cost-effective file serving solution that allows uploads directly to S3 from your site without using Pantheon as an intermediary.

See our documentation for Drupal and WordPress for more information about integrating S3 with your Pantheon site. Uploading large files over a slow local internet connection can cause the process to hit our Connection Timeout of 59 seconds. For example, a 10MB file uploaded on a 2Mbps connection may take too long and fail. You can use an upload time calculator like this one to help determine if your local internet connection is impeding file uploads to Pantheon.

Large backups take longer, use more resources, and have a higher likelihood of failing. Additionally, a GB compressed tarball is in itself not particularly convenient for anyone. For this reason, scheduled backups do not backup files for sites with footprints over GB although code and database are backed-up as normal.

Despite the lack of backups, file content is highly durable and stored on multiple servers. Pantheon may send a generic Maintenance Mode message during platform problems; this message cannot be customized.

Built-in Maintenance Mode for both Drupal and WordPress sites can be customized; clear caches when toggling. MariaDB This leads to Row size too large errors that are not present on earlier versions of MariaDB:.

Optionally, set the UUID from step 1 as the local alias replace site-uuid in this example :. For more information on how to diagnose tables and troubleshoot potential issues, refer to the official MariaDB documentation.

We do not support Drupal Multisite. As a workaround, developers can connect directly to MySQL and load files from their local machine:. Pantheon does not currently support modifying the nginx.

All of the containers run a standard profile, and we have opted to keep this configuration to keep the nginx. If your site uses nginx. If your site contains rules in nginx. Custom nginx. If running node. Each site supports a single Drupal or WordPress application.
