It makes sense. When the share installation is updated to SR2 by admin, how the user gets SR2 + his installation? Can '-clean' option work for it?

Then, when you install a new bundle 'foo', this goes in your local area. Now, your local bundles.info file contains all the bundles from the base + foo. When Eclipse launches, it checks that this is really the case (it checks that the shared bundles.info is a subset of the local one). I think there are two reasons for this. 1. The definition of 'shared' installs. If each user could update the base then this is not really 'shared' anymore. Some users have SR1, some have SR2, etc... 2. Consistency. If a users updates some bundles in the shared area, and then the admin updates the base, what should we use now? There could be other reasons for this too. cheers, ian On Thu, Aug 12, 2010 at 6:11 AM, Zhu, Mengxin (Kane) <kane....@windriver.com> wrote: I'm wondering what's the intent of current mechanism(* part in Ian's post) where picking up the bundles, share configuration or user configuration? I think it should load the bundles from user configuration if it exists, which is created and maintained by p2 as well. ________________________________ From: p2-dev-boun...@eclipse.org [mailto:p2-dev-boun...@eclipse.org] On Behalf Of Ian Bull Sent: Thursday, August 12, 2010 4:47 AM To: Eclipse Packaging Project; P2 developer discussions Subject: [p2-dev] Shared installs and our EPP Packages Hi everyone, There have been a number of bugs opened regarding shared installs not working [1,2,3,4,5,6]. While I don't know if they are all related, I have tracked down a configuration problem with some EPP packages that is causing this (at least it's causing it in some cases). In both Eclipse for Java Developers and the PHP package (I didn't check the others) there are bundles listed in the bundles.info file that are not in the p2 profile. When Eclipse is launched in a shared install scenario this configuration problem will limit our ability to install additional bundles. See below for the technical reasons*. While shared installs were not very common in the past, they are standard install on Windows 7 (when someone installs Eclipse in the C:\program files directory). So this means that anybody using an affected Helios package on Windows 7 (installed in c:\program files\) cannot install additional bundles using either the p2 UI or the MPC. So this brings up a few questions. 1. Is this a known problem? 2. Do we want to address this for SR1? 3. How are the Helios packages created? I created a helios package manually using the director command**, and it was configured properly. There must be additional steps that the helios epp builder is doing that I'm not aware of. There are also two p2 profiles in our EPP packages, which seems odd to me. [1] https://bugs.eclipse.org/bugs/show_bug.cgi?id=320153 [2] https://bugs.eclipse.org/bugs/show_bug.cgi?id=317896 [3] https://bugs.eclipse.org/bugs/show_bug.cgi?id=321239 [4] https://bugs.eclipse.org/bugs/show_bug.cgi?id=320383 [5] https://bugs.eclipse.org/bugs/show_bug.cgi?id=317897 [6] https://bugs.eclipse.org/bugs/show_bug.cgi?id=317757 * When we run in a shared install scenario, we create a bundles.info file from the p2 profile. When Eclipse is launched, our generated bundles.info file is checked against the shared one, and if any inconsistencies are found, we ignore ours and use the shared one. However, the shared one is read only, and will never contain the additional bundles. ** I used the following director command when installing an EPP package from the Helios repository: ./eclipse -application org.eclipse.equinox.p2.director -repository http://download.eclipse.org/releases/helios -installIU epp.package.java -destination /home/irbull/eclipse/eppinstall/ -profile eppProfile -p2.os linux -p2.ws gtk -p2.arch x86 cheers, ian -- R.
