Eclipse 3.4's new generation update manager p2

Eclipse3.4 is expected to be released on the 25 th of this month. Click here to download the 3.4 version, which is the 10th anniversary of the eclipse project. So far, there are 23 sub-projects in the Eclipse project, the Ganymede release introduced many highlights and provided many very good new features, which are convenient to use and specific features, you can open the Help content for the newly downloaded eclipse3.4, or view the online update history. This version is worth noting P2, a new eclipse supply platform (provisioning platform ). This is a substitute for the old update manager. For example, the old update manager can update and install eclipse from one or more remote sites, it is also the most common method for us to update, release, and install new features, but there are also some shortcomings, such as failure to update executable eclipse and process images. To solve these problems, a new generation of update mechanism was introduced at a BOF meeting in eclipsecon 2008. Then provisioning platform (P2 for short) was born and debuted at 3.4m5, unlike the previous eclipse update manager, bundle and non-bundle components (such as configuration files, installation files, and drawing resources) in P2 are allowed to be installed or updated, and P2 also allows the dropins directory, this makes it easier to install a bundle: you only need to copy the bundle to this directory. eclipse will automatically install and activate it, And eclipse may also be configured to share the bundle mode, this makes a bundle library available and the bundle library will serve different applications. For those who use eclipse in general usage, this does not show any benefit, but if you are developing (or supporting) RCP applications ), there are many RCP-based applications installed on the same machine (for example, an internal suite of RCP applications [in-house suite]), you can share these bundle among multiple applications, which saves much space.

The eclipse communication framework is responsible for downloading. You can also use several different computation methods (pack200w.tar.gz) to compress the product. Multiple images are also available for multi-threaded download. During the download process, if there is a problem with the update site, the previous update manager will fail, and P2 will automatically retry different images to find data. You can even download a 5 MB installer that installs eclipse and all its plug-ins.

In addition, when I used the update manager, I found that I could not connect to the proxy server. As a result, I could not use the update manager in the internal network of the company. Now I can use the proxy server in this 3.4 version, very convenient
