Remove the 'administer devel menu items' permissions for the Site Admin user role Remaining tasks. If you have one of those versions of the Zend optimizer and enable the Devel module it will possibly break your site and may end in a blank screen. Change drupal/devel to 5.1.0 in the composer.json file. The Devel module will not work with the old and buggy Zend optimizer 3.2.8 and below (and possibly 3.2.x in general). This is the only mode recommended for live sites.Ī settings option is available when using summary mode with APC, to exclude pages with less than a certain number of accesses. Summary is logged to APC, if installed, so as to not cause extra load on the database. Summary logging logs the average and maximum page generation time, average and maximum memory usage, last access time, and number of accesses for each path. The data includes page generation time in milliseconds, and the number of bytes allocated to PHP, time stamp. The module defaults to no logging at all.ĭetailed logging causes one database row to be written for each page load of the site. Settings to enable detailed logging or summary logging. This is useful for developers and site administrators alike to identify pages that are slow to generate or use excessive memory. View and log performance statistics for a site, such as page generation times, and memory usage, for each page load. ![]() Essential for developers of node access modules and useful for site admins in debugging problems with those modules. View the node access entries for the node(s) that are shown on a page. Similarly, a ddebug_backtrace() is offerred.Īccelerate development of your site or module by quickly generating nodes, comments, terms, users, and more. The summary includes how many times each query was executed on a page (shouldn't run same query multiple times), and how long each query took (short is good - use cache for complex queries).Īlso a dprint_r($array) function is provided, which pretty prints arrays. This module can print a summary of all database queries for each page request at the bottom of each page. Helper functions for Drupal developers and inquisitive admins. You’re a developer who has to write a user migration tool for a client.#D7CX: I pledge that Devel will have a full Drupal 7 release on the day that Drupal 7 is released.Ī suite of modules containing fun for module developers and themers. The right answer is to the use the surprisingly simple Batch API. Except that for every migration, there are seven (seemingly random) users that aren’t migrated. What is going on and how do you find out? Batch API is an abstraction layer for performing tasks, in this case migrating a block of users. Instead of loading a drupal page that runs a function to migrate all users, it loads a page that makes AJAX calls to run that function. We do this to avoid PHP timeouts and provide a better user experience. Instead of an endlessly loading white page we can see a themed page that includes a progress bar. However, when we use an abstraction layer, we lose knowledge of what is happening below. So how do we debug this kind of work? Using dprint_r() or dpm() might help here. ![]() You might arrive at the next page load with all your objects and debug messages printed to the screen, but you might not. It's unreliable enough for me to seek a better solution. Do you get an error message when trying to use the function. One problem could be that Drupal hasn't write access to your temp file dir, which is why you are not getting the file. And the indispensable devel module provides. 4 Answers Sorted by: 4 Your use of the function should be alright. dd() writes strings, arrays and objects to a temporary file instead of to the drupal webpage. That means you don’t have to wait for the batch process to finish to see what is happening. It’s also means your webpage's load time and html are intact. You use dd() just like var_dump() or dpm(). The webprofiler submodule was moved from Devel to WebProfiler project Devel 4 (and prior branches) are now minimally supported. It is the recommended release for Drupal 9 and 10.
