Summary [Qt] EWS bots should call qmake always

When the latest build suceeded and there isn't new SVN revision, buildHint in webkitdirs.pm isn't "incremental", but "". It is correct behaviour for developer build, but it isn't for EWS. Unfortunately it can cause and it causes incremental build problems on the EWS bots sometimes. Here is an example: https://bugs.webkit.org/show_bug.cgi?id=89939 I'm going to check how can we make the EWS bots do full incremental build always (call qmake always to regenerate dependency) to avoid these false positive alarms. Tor Arne, if you have any idea how to fix it, please share with me. :) Thanks in advance.

One option would be to run build-webkit with --makeargs=incremental

(In reply to comment #1) > One option would be to run build-webkit with --makeargs=incremental Thanks, it is the best option. We don't have to modify anything in the build system. I added the following env to our EWS config: export BUILD_WEBKIT_ARGS=--makeargs=incremental Now it works fine. ;-)

Reopen, because "export BUILD_WEBKIT_ARGS=--makeargs=incremental" wasn't a good idea. Because now it causes many false negative red EWS bubbles. The problem is when a patch changes any configuration which triggers "make wipeclean" before anything else. But in this case "make incremental wipeclean" is called, which is incorrect, and makes the build fail because of race condition. I think we should handle it in webkitdirs.pm and set $needsIncrementalBuild if CONFIG+=buildbot is used instead of setting this buggy env on the EWS bots. Patch is coming.
