This is the whole list we require in p2.user.ui.feature
Making the switch now. Exactly what bundles are required? I now have the following ecf filetransfer bundles in my feature: org.eclipse.ecf.filetransfer org.eclipse.ecf.provider.filetransfer org.eclipse.ecf.provider.filetransfer.httpclient org.eclipse.ecf.provider.filetransfer.httpclient.ssl org.eclipse.ecf.provider.filetransfer.ssl are all of them needed or do I have redundancy now? I also added: org.apache.commons.httpclient org.apache.commons.codec org.apache.commons.logging since they now seem to be required. - thomas Pascal Rapicault wrote:
I think my problem (or at least part of it) stems from the fact that I don't include the Apache httpclient in my setup so I don't benefit from the automatic retries that apparently take place there but not in the standard URL connect. - thomas Henrik Lindberg wrote:
perhaps a very simply workaround is to allow the timeout and retry to be set via properties.

I have entered this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=276300 If mirrors were present you would get very different behaviour, since we retry once per available mirror. With no mirrors and a two minute timeout contacting the main server, I'm not sure we could do a lot better. Henrik described the problem very well - there is no perfect retry policy that makes sense for both headless builds and end users, so it's a difficult problem.
I know that there's been some improvements in this area since M7 which I'm currently using but I thought I might ask anyway. What kind of socket timeouts do we have and do we make any attempt to retry when a socket timeout exception is thrown? I tried installing the org.eclipse.platform feature several times. I always ran into a SocketTimeoutException (see stacktrace below). Apparently it tries to download the packed file first and then the jar file. If neither succeeds, the installation fails. I first tried this on my local machine. I almost always failed so I decided to move to build.eclipse.org. As it turns out, it fails there too. So what's going on here? Does it contact mirrors that fails or what? I'm explicitly trying to install from http://download.eclipse.org/eclipse/updates/3.5milestones/S-3.5M7-I200904302300. Here's the stack-trace that I'm getting 7 times out of ten (the bundle that failes question vary): [java] !MESSAGE Unable to read repository at http://download.eclipse.org/eclipse/updates/3.5milestones/S-3.5M7-I200904302300/plugins/org.eclipse.update.ui_3.2.200.v20090213.jar.pack.gz.
