How to fix   Duplicated Code    Complexity   

Duplicated Code

Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.

Common duplication problems, and corresponding solutions are:

Complex Class

 Tip:   Before tackling complexity, make sure that you eliminate any duplication first. This often can reduce the size of classes significantly.

Complex classes like TDBMService often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

While breaking up the class, it is a good idea to analyze how other classes use TDBMService, and based on these observations, apply Extract Interface, too.

Documentation Bug introduced by
It seems like new \Mouf\Database\TDBM\StandardObjectStorage() of type object<Mouf\Database\TDBM\StandardObjectStorage> is incompatible with the declared type object<Mouf\Database\TDBM\WeakrefObjectStorage> of property $objectStorage.

Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property.

Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property..

Duplication introduced by
This code seems to be duplicated across your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.

     * Returns a TDBMObject associated from table "$table_name".
211
     * If the $filters parameter is an int/string, the object returned will be the object whose primary key = $filters.
212
     * $filters can also be a set of TDBM_Filters (see the findObjects method for more details).
213
     *
214
     * For instance, if there is a table 'users', with a primary key on column 'user_id' and a column 'user_name', then
215
     * 			$user = $tdbmService->getObject('users',1);
216
     * 			echo $user->name;
217
     * will return the name of the user whose user_id is one.
218
     *
219
     * If a table has a primary key over several columns, you should pass to $id an array containing the the value of the various columns.
220
     * For instance:
221
     * 			$group = $tdbmService->getObject('groups',array(1,2));
222
     *
223
     * Note that TDBMObject performs caching for you. If you get twice the same object, the reference of the object you will get
224
     * will be the same.
225
     *
226
     * For instance:
227
     * 			$user1 = $tdbmService->getObject('users',1);
228
     * 			$user2 = $tdbmService->getObject('users',1);
229

     * 			echo $user2->name;
231
     * will return 'John Doe'.
232
     *
233
     * You can use filters instead of passing the primary key. For instance:
234
     * 			$user = $tdbmService->getObject('users',new EqualFilter('users', 'login', 'jdoe'));
235
     * This will return the user whose login is 'jdoe'.
236
     * Please note that if 2 users have the jdoe login in database, the method will throw a TDBM_DuplicateRowException.
237
     *
238
     * Also, you can specify the return class for the object (provided the return class extends TDBMObject).
239
     * For instance:
240
     *  	$user = $tdbmService->getObject('users',1,'User');
241
     * will return an object from the "User" class. The "User" class must extend the "TDBMObject" class.
242
     * Please be sure not to override any method or any property unless you perfectly know what you are doing!
243
     *
244
     * @param string $table_name   The name of the table we retrieve an object from.
245
     * @param mixed  $filters      If the filter is a string/integer, it will be considered as the id of the object (the value of the primary key). Otherwise, it can be a filter bag (see the filterbag parameter of the findObjects method for more details about filter bags)
246
     * @param string $className    Optional: The name of the class to instanciate. This class must extend the TDBMObject class. If none is specified, a TDBMObject instance will be returned.
247
     * @param bool   $lazy_loading If set to true, and if the primary key is passed in parameter of getObject, the object will not be queried in database. It will be queried when you first try to access a column. If at that time the object cannot be found in database, an exception will be thrown.

Unused Code Comprehensibility introduced by
43% of this comment could be valid code. Did you maybe forget this after debugging?

Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it.

The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.

This check looks for comments that seem to be mostly valid code and reports them.

Bug introduced by
The method deleteAll() does not exist on Doctrine\Common\Cache\Cache. Did you maybe mean delete()?

This check marks calls to methods that do not seem to exist on an object.

This is most likely the result of a method being renamed without all references to it being renamed likewise.

Unused Code Comprehensibility introduced by
59% of this comment could be valid code. Did you maybe forget this after debugging?

Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it.

The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.

This check looks for comments that seem to be mostly valid code and reports them.

     * (Note: if you want to query the database for an object by its primary key, use the findObjectByPk method).
1174
     *
1175
     * The findObjects method takes in parameter:
1176
     * 	- mainTable: the kind of bean you want to retrieve. In TDBM, a bean matches a database row, so the
1177
     * 			`$mainTable` parameter should be the name of an existing table in database.

     *  - filter: The filter is a filter bag. It is what you use to filter your request (the WHERE part in SQL).
1179
     *          It can be a string (SQL Where clause), or even a bean or an associative array (key = column to filter, value = value to find)
1180
     *  - parameters: The parameters used in the filter. If you pass a SQL string as a filter, be sure to avoid
1181
     *          concatenating parameters in the string (this leads to SQL injection and also to poor caching performance).
1182
     *          Instead, please consider passing parameters (see documentation for more details).

1186
     *
1187
     * The `findObjects` method will return a `ResultIterator`. A `ResultIterator` is an object that behaves as an array

Duplication introduced by
This code seems to be duplicated across your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.

Bug introduced by
The variable $typesForTable seems only to be defined at a later point. As such the call to isset() seems to always evaluate to false.

This check marks calls to isset(...) or empty(...) that are found before the variable itself is defined. These will always have the same result.

This is likely the result of code being shifted around. Consider removing these calls.

Coding Style Comprehensibility introduced by
$typesForTable was never initialized. Although not strictly required by PHP, it is generally a good practice to add $typesForTable = array(); before regardless.

Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code.

Let’s take a look at an example:

foreach ($collection as $item) {
    $myArray['foo'] = $item->getFoo();

    if ($item->hasBar()) {
        $myArray['bar'] = $item->getBar();
    }

    // do something with $myArray
}

As you can see in this example, the array $myArray is initialized the first time when the foreach loop is entered. You can also see that the value of the bar key is only written conditionally; thus, its value might result from a previous iteration.

This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization $myArray = array() either outside or inside the foreach loop.
