Re: [cross-project-issues-dev] [ide-dev] Start collecting requests for Error Reporting v2


there are four (4) + one (1) mechanisms in place that will / can limit the traffic to

Level 1: A local, persistent, per-workspace history that remembers what was send before. If an error is logged that has the same fingerprint as an already sent report, it is skipped. This should prevent clients to send the same error over and over again.

Level 2: A “known errors database” that get’s downloaded from on IDE startup. If an error is logged in the IDE which was marked as “ignored” in the known-errors database, it won’t be send. No network traffic will happen. The server-side generates this database on demand and set’s every problem to ignore that was reported by more than 50 users.

Level 3: The “emergency” power OFF switch [1]. On startup, we check whether a certain system status URL is reachable. If that fails, the system deactivates the reporter until next restart of Eclipse.

Level 4: If Eclipse is started with ‑Dorg.eclipse.epp.logging.aeri.ui.skipReports=true, no errors will be sent. EPP packages may add this into the eclipse.ini in worst case.

Level 5: I’m not sure what exactly would happen if the firewall blocks access the service. But I assume we catch every exception and log it gracefully as a warning. So this looks like Level 5 to me.

However, the traffic may still be large - especially in the first days. In that case I’m happy to pull the plug via Option 3 or Level 4 by rebuilding the EPP packages. Or 5 if you don’t see any other option. Or we start with just one EPP (e.g. Committers and or Java) package for the release and add more until we are sure it works. I think we have all options in your hands to control it on various levels.

Regarding Reporting to Bugzilla: Yes, the traffic goes to* If this server is shut down, nothing can ever go to Bugzilla. 

I hope I'll keep my account for a while… still crossing fingers, though.

Do we have an OFF switch somewhere so that we can turn these things off if we see we're going to get flooded?

Have we...?
Do you...?

I have a big "OFF" switch called a firewall, but I'm not sure how that will manifest itself in Eclipse if the error reporter cannot connect to its home site.

Also, just so I understand, the 1000's of daily reports  (which could become 100,000's of daily reports on June 25) are all reports against the recommenders server, right?  Not Bugzilla bugs, right? The latter could see the OFF switch extended to your user account :)

I will be at ECE to collect on any wrongdoings you do to your fellow committers.

In all seriousness, let me know if there's anything I can do to make sure we're prepared for what is about to come.
