I've decoupled `Cookie` from the actual act of setting and getting
cookies. Currently there are a few limitations to how Cookie works that
this change mitigates:
0. `Cookie` currently changes the super global `$_COOKIE` when setting
to make the state of an application a bit more managable, but this is
bad because we shouldn't be modifying super globals
0. One can't actually change the `$cookie_class` once the
`Cookie::$inst` has been instantiated
0. One can't test cookies as there is no class that holds the state of
the cookies (it's just held in the super global which is reset as part
of `Director::test()`
0. One can't tell the origin of a cookie (eg: did the application set it
and it needs to be sent, or did we receive it from the browser?)
0. `time()` was used, so testing was made difficult
0. There was no way to get all the cookies at once (without accessing
the super global)
Todos are on the phpdoc and I'd like to write some tests for the backend
as well as update the docs (if there are any) around cookies.
DOCS Adding `Cookie` docs
Explains basic usage of `Cookie` as well as how the `Cookie_Backend`
controls the setting and getting of cookies and manages state of sent vs
received cookies
Fixing `Cookie` usage
`Cookie` is being used inconsistently with the API throughout framework.
Either by not using `force_expiry` to expire cookies or setting them to
null and then expiring them (which is redundant).
NEW `Director::test()` takes `Cookie_Backend` rather than `array` for `$cookies` param
Database abstraction broken up into controller, connector, query builder, and schema manager, each independently configurable via YAML / Injector
Creation of new DBQueryGenerator for database specific generation of SQL
Support for parameterised queries, move of code base to use these over escaped conditions
Refactor of SQLQuery into separate query classes for each of INSERT UPDATE DELETE and SELECT
Support for PDO
Installation process upgraded to use new ORM
SS_DatabaseException created to handle database errors, maintaining details of raw sql and parameter details for user code designed interested in that data.
Renamed DB static methods to conform correctly to naming conventions (e.g. DB::getConn -> DB::get_conn)
3.2 upgrade docs
Performance Optimisation and simplification of code to use more concise API
API Ability for database adapters to register extensions to ConfigureFromEnv.php
Changed Fragment links to Anchor links, however it's is slighty confusing what the right name for the thing is.
According to w3.org: "Some URIs refer to a location within a resource. This kind of URI ends with "#" followed by an anchor identifier (called the fragment identifier)." - http://www.w3.org/TR/html401/intro/intro.html#fragment-uri
After doing some research in the most common used name for the #some-link identifier I came to the conclusion that most of the time (about 70% on StackOverflow/BlogArticles/Interwebz) Anchor-link was the term used to describe the identifier. Imho, Anchor is the prefered term for the identifier.
Is it acceptable to change fragment to anchor, since it seems more used?
Corrected many broken link-renderings. Also removed the "Related" link to [genericviews Module](http://silverstripe.org/generic-views-module) because it doesn't work, and I can't it elswhere.
There's no way to make things like [api:DataObject->beforeUpdateCMSFields()] work, is there?
I removed those kind of api tags (the links yielded a 404 page), and corrected a few other link-rendering issues.
CustomMember was extending the wrong class to be able to reference $this->owner.
Also, changed CustomMember to MyMemberExtension to remain consistent with the initial example.
BUG Resolve issue with DirectorTest breaking RequestProcessor
Injector::nest and Injector::unnest are introduced to better support sandboxing of testings.
Injector and Config ::nest and ::unnest support chaining
Test cases for both Injector::nest and Config::nest
Removed ; at the end of ->setConfig('dmyfields', true) in the three chain example. Is confusing for new users/developers who are not aware of how to chain methods.
Closes#3006
