Moodle 3.3 Database schema / Zoola Analytics

Searching the Moodle database schema is no longer a challenge and table fields names and purposes are no longer a mystery 🙂

With the Zoola analytics DB schema explorer, we can now search and filter tables, table fields, and explorer 1st and 2nd level external key connections between tables.

Check your PHP project for known security issues – SensioLabs Security Advisories Checker

“You manage your PHP project dependencies with Composer, right? But are you sure that your project is not dependent on a package with known security issues? The SensioLabs security advisories checker is a simple tool, available as a web service or as an online application, that uses the information from your composer.lock file to check for known security vulnerabilities. This checker is a frontend for the security advisories database.” / SensioLabs.

phpcs-security-audit – PHP_CodeSniffer

phpcs-security-audit is a set of PHP_CodeSniffer rules that finds flaws or weaknesses related to security in PHP and its popular CMS or frameworks.

It currently has core PHP rules as well as Drupal 7 specific rules. Next planned CMS/framework is Symfony 2, which are also relevant to Moodle.

As a bonus set of rules, the tool also check for CVE issues and security advisories related to CMS/framework. You can use it in order to follow the versioning of components during static code analysis.

The main reasons of this project for being an extension of PHP_CodeSniffer is to have easy integration into continuous integration systems and to be able to find security bugs that are not detected with object oriented analysis (like in RIPS or PHPMD).

phpcs-security-audit is backed by Floe design + technologies and written by Jonathan Marcil.

Netflix/dynomite: A generic master-master dynamo implementation for different k-v storage engines – Redis and Memcached

As the request goes through a Dynomite node, the data gets replicated and eventually stored in the target storage. The data can then be read back either through Dynomite or directly from the underlying storage’s API.

Dynomite and the target storage engine run on the same node. Clients connect to Dynomite, and requests are proxied to either the storage engine on the same node or to Dynomite processes running on other nodes.

Dynomite, inspired by Dynamo whitepaper, is a thin, distributed dynamo layer for different storage engines and protocols. Currently these include Redis and Memcached. Dynomite supports multi-datacenter replication and is designed for high availability.

The ultimate goal with Dynomite is to be able to implement high availability and cross-datacenter replication on storage engines that do not inherently provide that functionality. The implementation is efficient, not complex (few moving parts), and highly performant.

jokkedk/webgrind: Xdebug Profiling Web Frontend in PHP

Webgrind is a Xdebug profiling web frontend in PHP. It implements a subset of the features of kcachegrind and installs in seconds and works on all platforms. For quick’n’dirty optimizations it does the job. Here’s a screenshot showing the output from profiling:

Features

  • Super simple, cross platform installation – obviously 🙂
  • Track time spent in functions by self cost or inclusive cost. Inclusive cost is time inside function + calls to other functions.
  • See if time is spent in internal or user functions.
  • See where any function was called from and which functions it calls.
  • Generate a call graph using gprof2dot.py

Suggestions for improvements and new features are more than welcome – this is just a start.
