[Buildbot-devel] Mercurial clobbers on changehook?

[Marcus Lindblom]

Hi all,

I noticed that our Mercurial still does a full clone when the 
change-hook triggers a build (which takes time and also rebuilds much 
more than necessary). We're creeping up on 10 minutes build time now at 
our place, and with an additional 10 minutes of tests, feedback isn't 
speedy enough.

However, if I manually force the build, it only does pull+update, which 
is what I'd expect all the time.

We ought to get this fixed properly, but Buildbot seems to decide to 
clobber (or do a full update) before my rewrites (and the 
dontclobberonbranchchange fix). I tried looking at the code again but I 
can't really see what's causing this.

Any ideas? (Perhaps it's just my setup.)

Cheers,
/Marcus
