Nightly Slave workspace cleanup - unintentional

[Jaap de Jong]

Hi All,

Every night old workspaces on my jenkins slave are cleaned and I have not configured this, never!

I can not find where this is configured. Is this perhaps new default behavior?

Not sure when this started, but might be since installing 2.64.

Any help is appreciated!

Thanks in advance

https://wiki.jenkins-ci.org/display/JENKINS/Features+controlled+by+system+properties apparently nothing changed recently, introduced in 1.608.

Though, beware this IMO: I would possibly raise the timing if you have data size issues and cannot improve it in the short term, but disabling this seems *very* dangerous to me, and is likely to lead to make your agents become snowflake and encourage config drift.

Wiping out everything and starting from scratch as often as possible is the only way to make sure your testing are stable and you're not going to hit the flaky tests/build wall when you expect it the least...

BTW the default behaviour is actually already what you want: hudson.model.WorkspaceCleanupThread.retainForDays is 30 days, so it's very conservative.

So either something changed on your side, or you're seeing a bug that may need to be reported (with reproduction steps, as always, if you want to raise your chance to see it fixed reasonably quickly).

Thanks Mathus

This is really helpful for the short term. 

Changes on my side? Yeah, its probably more than the 30 days ago when building the projects...

And yes, you are right, building from scratch is better, at least every now and then.

It would even be better to always start from scratch!
