Automated git pull in a more protected environment

Submitted by nk on Fri, 2012-12-21 20:17

Almost exactly a year ago I wrote about automating git pull from github. I found myself in an environment where a) I wanted to do this b) PHP had been set up so that git pull didn't work. inotifytools to the rescue. First, write a password-like filename (see the old post) PHP script like this:

file_put_contents('pull/git', '');

Then write a bash script:
cd ~/public_html
while inotifywait -qre close_write pull
  git pull

Drupal 8 progress from my / MongoDB perspective: update #10

Submitted by nk on Wed, 2012-12-12 22:17

I have changed course and speed seemingly because now we are so beyond tresholds that feature patches can't get in. So we are in bugfix mode and I have chosen performance ones because those will help in a lot of ways: it will kill a lot of majors and criticals and also speed up testing which helps development overall. Also, the EntityQuery relationship patch relies on converting everything to the new Entity API and that can't happen if it's slow.

Drupal 8 progress from my / MongoDB perspective: update #9

Submitted by nk on Fri, 2012-11-30 06:07

Finally the kernel work is complete: right after settings.php is read, the compiled service container is read and used and there is no other service container being used (while I worked a lot on the early part the previous weeks, this week was mostly the One Container To Rule Them All patch). This means MongoBundle can override everything in the service container easily.

Drupal 8 progress from my / MongoDB perspective: update #8

Another week, another kernel patch. This one moves the kernel initialization to very, very early in the bootstrap process, just after settings.php is read. So, the MongoBundle can override everything easily. Great! There's a patch in the queue which I will turn my attention to once this is in which puts the database service in the kernel. More on this a little later.

Drupal 8 progress from my / MongoDB perspective: update #7

Submitted by nk on Mon, 2012-11-12 22:39

The new DrupalKernel patch is ready. This will unify the bootstrap and the "real" service container and compile them to disk. Very important for us. Also, I had a rift with another developer for too long but in this issue we finally managed (although it's visible we both struggled) to work together and get to an agreement. I am very hopeful this trend continues.

Drupal 8 progress from my / MongoDB perspective: update #6

Submitted by nk on Mon, 2012-11-05 06:29

So Views and Twig are both in Drupal 8 alongside with a configuration import and an entity translation UI. Big, big progress in general. On my end, EFQ v2 has been committed. Now I am doing a number of things in parallel: one, I am rewriting the batch API and have buy in from Crell, bojanz and yched (and I think berdir is OK with it too) so I expect that to get in once it's more completed. We have decided on not supporting "call me again" jobs, just clean, explicit job creation. A new queue operation seems necessarily -- which is move to the end of the queue.

So you want backwards compatibility?

The comment property on the node property is being refactored into a field. Let's pretend -- just because it's a great example not because we want to postpone it -- this happens during Drupal 9! Modules using $node->comment break but modules using $node->get('comment') don't. Modules running SQL queries against {node}.comment break but modules running entity queries with entity_query('node')->condition('comment', 1) do not.

How does the compilation of the Dependency Injection Container to disk affect hosts?

Submitted by nk on Mon, 2012-10-22 22:52

The Dependency Injection Container is now written to disk. When there is no container file available then the DIC is compiled and if the storage backend is writeable then it is written to disk. By default this is written in a tricky (slightly slower but more secure) way into the public files directory.

Drupal 8 progress from my / MongoDB perspective: update #5

Submitted by nk on Mon, 2012-10-22 12:48

The EntityFieldQuery rewrite is progressing well, finally had a good review from fago. The following patch had a 36KB interdiff on a 120KB patch. Such is life in Drupal core: you try to write something to the best of your abilities, someone smarter comes along, you adjust your code. Now your code and yourself is better if you take the effort to learn from it.

PHP closures are very simple

Submitted by nk on Sun, 2012-10-14 06:17

Closures seem like big magic but in PHP they are just syntactic sugar over the following construct:

class OurClosure {
__construct($add) {
$this->add = $add;
__invoke($x) {
$x + $this->add;
$print_add_2 = new OurClosure(2); // call __construct
$print_add_2(5); // when an object is called like a function it calls __invoke

Now, closures use the following syntax:
function get_add_printer($add) {
return function ($x) use ($add) {
print $x + $add;
print "\n";
