Re: [p2-dev] Brittle downloads
|
Hi,
I worked on timeout for connect recently, and I know that connect has
a timeout of 120 seconds. Without actually testing read timeout, I
know that it is setup to be 120 seconds as well. This was done because
of discussion in https://bugs.eclipse.org/bugs/show_bug.cgi?id=266246.
(This is when using httpClient).
I don't think there are any retries.
Don't know if the problem is because you are hitting a bad mirror, but
it does not look like it because the exception message is showing the
full URL to the artifact (as opposed to just the repository URL) - but
I am not 100% sure.

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):
