Safari (web browser)

From Free net encyclopedia

Template:Infobox Software Safari is a web browser developed by Apple Computer, Inc. and available as part of its Mac OS X operating system. It was included as the default browser in Mac OS X v10.3 (Panther) and is the only browser bundled with Mac OS X v10.4 (Tiger).

Safari uses Apple's brushed metal user interface, has a bookmark management scheme that functions like the iTunes jukebox software, integrates Apple's QuickTime multimedia technology, and features a tabbed-browsing interface similar to that of Mozilla. A Google search box is a standard component of the Safari interface, as are software services which automatically fill out Web forms and spellcheck entries into web page text fields. The browser also includes an integrated pop-up ad blocker.

As of early 2006, Safari has a usage share of about 2%.

History and development

Until 1997, Apple Macintosh computers had shipped with Netscape Navigator. Microsoft's Internet Explorer for Mac was subsequently included as the default web browser as part of the five-year agreement between Apple and Microsoft. Microsoft released five major versions of Internet Explorer for Mac, with the last one being released on March 27 2000.

On January 7 2003, Steve Jobs announced that Apple had developed in house their own web browser called Safari. They released the first beta version that day and a number of official and unofficial beta versions followed, until they released version 1.0 on June 23. Available as a separate download initially, it was included with Mac OS X v10.3 on release on October 24 as the default browser, with Internet Explorer for Mac included only as an alternative browser. Since the release of Mac OS X v10.4 in April 29 2005, Safari is the only web browser included with the operating system.

Safari uses Apple's WebKit for rendering web pages and running JavaScript. WebKit consists of WebCore (based on Konqueror's KHTML engine) and JavaScriptCore (based on KDE's kjs JavaScript engine). Like KHTML and kjs, WebCore and JavaScriptCore are free software and are released under the terms of the GNU Lesser General Public License. Some Apple improvements to the KHTML code are merged back into the Konqueror project. Apple also releases additional code under an open source 2-clause BSD-like license.

In June 2005, after some criticism from KHTML developers over lack of access to change logs, Apple moved the development source code and bug tracking of WebCore and JavaScriptCore to OpenDarwin.org. WebKit itself was also released as open source. The source code for non-renderer aspects of the browser, such as its GUI elements, remains proprietary.

Version 2.0 of Safari, released on April 29 2005 includes a built in RSS and Atom reader. Other features include private browsing (which does not record any information of your web visit), the ability to archive and e-mail webpages, the ability to search bookmarks, and a reported 1.8x speed boost over version 1.2.4.

In April 2005, Dave Hyatt, one of the Safari developers at Apple, documented his progress fixing bugs in Safari to get it to pass the Acid2 test. On April 27 he announced that his development version of Safari now passed the test, making it the first web browser to do so. [1] The changes were not initially available to end-users unless they downloaded and compiled the WebKit source code themselves or ran one of the nightly automated builds available at opendarwin.org. [2] However on October 31, Apple released version 2.0.2 of Safari that included the Acid2 bug fixes.
