| 27 | <h1>Backwards incompatibilities in log4javascript 1.4</h1>
|
| 28 | <ul>
|
| 29 | <li>
|
| 30 | Loggers are now hierarchical. This means logger names containing full stops have
|
| 31 | special meaning. For example, from version 1.4 the logger named <code>myapp.ajax</code>
|
| 32 | by default inherits all the appenders of the logger named <code>myapp</code>, while
|
| 33 | prior to version 1.4 these loggers would be entirely independent;
|
| 34 | </li>
|
| 35 | <li>
|
| 36 | The signature of the <code>log</code> method of <code>Logger</code> has changed.
|
| 37 | However, you should not use this method directly; instead, use one of the level-specific
|
| 38 | wrapper functions (<code>debug</code>, <code>info</code>, <code>error</code> etc.);
|
| 39 | </li>
|
| 40 | <li>
|
| 41 | Appenders can no longer be configured via constructor parameters. Instead you must use
|
| 42 | setter methods;
|
| 43 | </li>
|
| 44 | <li>
|
| 45 | The format of requests sent via <code><a href="manual.html#ajaxappender">AjaxAppender</a></code>
|
| 46 | has changed when using <code><a href="manual.html#jsonlayout">JsonLayout</a></code> or
|
| 47 | <code><a href="manual.html#xmllayout">XmlLayout</a></code>: the formatted log messages are sent
|
| 48 | as a name-value pair (with default name <code>data</code>) rather than a single unencoded string;
|
| 49 | </li>
|
| 50 | <li>
|
| 51 | All timestamps returned by <code><a href="manual.html#xmllayout">XmlLayout</a></code>,
|
| 52 | <code><a href="manual.html#jsonlayout">JsonLayout</a></code> and
|
| 53 | <code><a href="manual.html#httppostdatlayout">HttpPostDataLayout</a></code> are
|
| 54 | now measured in milliseconds since January 1st 1970 (previously they were returned
|
| 55 | as seconds since January 1st 1970);
|
| 56 | </li>
|
| 57 | <li>
|
| 58 | The constructors for <a href="manual.html#jsonlayout">JsonLayout</a> and
|
| 59 | <a href="manual.html#httppostdatlayout">HttpPostDataLayout</a> have changed; the property names
|
| 60 | used for the properties of the logging event are now set via <code>setKeys</code> rather than
|
| 61 | in the constructor;
|
| 62 | </li>
|
| 63 | <li>
|
| 64 | <code>setReadable</code> has been removed from <a href="manual.html#jsonlayout">JsonLayout</a>.
|
| 65 | The <code>readable</code> property should now be set via the constructor;
|
| 66 | </li>
|
| 67 | <li>
|
| 68 | <code>addErrorListener</code> and <code>removeErrorListener</code> removed from
|
| 69 | the <code>log4javascript</code> object and replaced with the more generic
|
| 70 | <code><a href="manual.html#log4javascriptaddeventlistener">addEventListener</a></code>
|
| 71 | and <code>removeEventListener</code> methods. The listener functions are passed
|
| 72 | different parameters.
|
| 73 | </li>
|
| 74 | </ul>
