Re: [cross-project-issues-dev] New UUID in Eclipse Platform

I forgot to add that this is not worth than an IPv6 address.

Hi Ian,

Sorry I will have to be "that guy", but I do find this a bit concerning.

First, The eclipse.uuid file is put in the user's home directory, which means that it ends up identifying a *user*, not just an Eclipse installation. If the same user wipes his installation and re-installs another Ecilpse, he keeps the same ID.

This is also done by default, with no warning to the user. Even proprietary programs often pop a window on the first run, asking the user if they want to provide anonymous usage statistics and the like, and giving them the option to disable it. Even if that option is enabled by default in the dialog, that is still miles better than not telling the user about it at all, and requiring him to know about an obscure "eclipse.uuid=0" configuration option.

I realize I'm late to the party and the decision has already been made, but you said to let you know if we have questions or concerns, so I am doing just that ;)

I wanted to make everyone aware that a UUID has been added to the Eclipse Platform [1] and is available in the current Neon RC. This was done at the
request of the Eclipse Foundation.

The UUID is automatically generated and stored in the
${user.home}/.eclipse/eclipse.uuid file. The UUID does not contain any
personally identifiable information. If a user do not want to have this
property set they are instructed to set eclipse.uuid=0. Information about
the UUID has been included in the Eclipse Platform N&N [2].

The UUID will be automatically added to the user-agent of http requests to
* servers. For Neon, the projects that make these types of
requests include p2 [1], MPC [3] and AERI [4]. I would expect other projects
will add a uuid in the future.

The immediate questions for many people are 1) why are we doing this, and 2)
what about the privacy concerns.  Let me attempt to answer both of these

Why are we doing this?

The Eclipse Foundation has started an program to better understand our user community. We are using a log file analysis service, Splunk, to analyze many of our log files to get a better idea of how people are using Eclipse. For instance, how many people actively use Eclipse, what version of Java is the
most popular with the Eclipse user community, what version of Eclipse
Platform is being used or what operating system is being used? In the past,
this type of information was typically a 'best guess'. We believe can do
better by having the actual data of our user community. The UUID will allow
us to get a more accurate answer to many of these questions.

What about the privacy concerns?

The UUID is anonymous and does not contain personably identifiable
information. We only intend to use and analyze the UUID at an aggregate
level. A user is able to opt-out of sending a UUID by setting
eclipse.uuid=0. The Eclipse Foundation has a published Privacy Policy [5]
that details our specific practices.

Please let me know if you have any questions or concerns. I appreciate this might be a sensitive topic but I do believe it is the right thing to do for
the Eclipse community.
