UPDATE 2015-12-04 : Tinytest is now documented, for the upcoming Meteor 1.3 release. See the official README.md. Better use the official information than my unofficial cheatsheet.
hook_requirements(), which is supposed to be present in the module install file, not the module itself: when called at runtime for the site report page, the module is loaded and the PSR/4 autoloader works fine. However, when that hook is fired during install to ensure the module can indeed be enabled, the module is not yet enabled, and the autoloader is not yet able to find code from that module, meaning the
hook_requirements('install')implementation cannot use namespaced classes from the module, as they will not be autoloadable. What are the solutions ?
One nice thing during Drupal 7/8 development is the ability, thanks to the
devel module, to get a list of all SQL queries ran on a page. As I've been working quite a bit on MongoDB in PHP recently, I wondered how to obtain comparable results when using MongoDB in PHP projects. Looking at the D7 implementation, the magic happens in the
// Start logging on the default database.
// Get the log contents, typically in a shutdown handler.
$log = \Database::getLog(DB_CHANNEL);
With DBTNG, that's all it takes, and devel puts it to good use UI-wise. So is there be an equivalent mechanism in MongoDB ? Of course there is !
While porting (well, actually rewriting) an old PHP library to Go, I had to use a CRC (cyclic redundancy check) on a buffer. In old-school PHP, the standard is well established since PHP 4: just use
crc32 from the
strings package, and beware of the sign bit or, to be a bit more current while still compatible, use the
hash() function from the
hash package, like this example:
One of the interesting aspects of the revamped menu/links system in Drupal 8 is the fact that menu links are now in easily parseable YAML files, the "(module).links.menu.yml" in each module, in which each menu link can be bound to its parent link, hopefully producing a tree-like structure.
If you program in Go, you've probably written a lot of packages, and probably split packages in subpackages. Maybe even more than idiomatic Go would really advise... And you may have been grumbling just like I did at the fact that the
go test command requires a list of packages, and does not recursively dive into all the subpackages, like PHPunit would, and does not seem to have a working recursion flag.
Call a method on a nil pointer (null object) ? This is a classical bug. What if it somehow turned out to be a valid and useful construct in some languages, say in Go ? And what about PHP ?
I've long been receiving quite high volumes of comment spam on this blog, which is why comments have always been pre-moderated. And, of course, there is usually not much to think of it. Not so with one of the spam messages posted today, which unwittingly provided an unexpected insight into the current mechanisms uses by spammers.
Go syntax has some funny peculiarities which are not immediately obvious, like methods on primitive types. Let's have a look.
Primitive wrapper types
Anyone with a few hours of Go is familiar with the basic object notation, like this example:
One litle-publicized feature of the BeeGo Go framework is its admin dashboard.
Although it may look quite raw visually (think MIME: text/plain), it contains a wealth of information about goroutines, threads, memory usage, and request statistics. It even allows devs to add to a "healthcheck" list, and admins allowed dashboard access to run "tasks" defined in code. The diagram belows shows the hierarchy of features in the version coming with Beego 1.3.0.
