[Win] Fix the broken clean build which makes the EWS unreliable

[Csaba Osztrogonác]

Apple Windows EWS rejects all patches with these false positive failure:

  /home/buildbot/WebKit/Source/WebCore/DerivedSources.make:893: recipe for target 'XMLViewerCSS.h' failed
  python /home/buildbot/WebKit/WebKitBuild/Release/include/private/JavaScriptCore/jsmin.py </home/buildbot/WebKit/Source/WebCore/inspector/CommandLineAPIModuleSource.js >> ./CommandLineAPIModuleSource.min.js

It seems it isn't an EWS issue, but a sesrious incremental build issue.
I managed to reproduce it on the Windows buildbots too: (with clean build)
- https://build.webkit.org/builders/Apple%20Win%20Release%20%28Build%29/builds/71337
- https://build.webkit.org/builders/Apple%20Win%20Debug%20%28Build%29/builds/89353

Any plan to fix the Windows build? It isn't good that Windows 
EWS reports false positive build failures for each patch. :((

[Csaba Osztrogonác]

The clean build is still broken:
- https://build.webkit.org/builders/Apple%20Win%20Release%20%28Build%29/builds/71403
- https://build.webkit.org/builders/Apple%20Win%20Debug%20%28Build%29/builds/89420

And the Win EWS still reports false positive failures due to this bug.

While this obviously needs to be fixed, I'm also puzzled about how this causes false positives on EWS.

[Csaba Osztrogonác]

The clean build is still broken:
https://build.webkit.org/builders/Apple%20Win%20Release%20%28Build%29/builds/71684

And the EWS still reports false positive failures. :(

Are you planning to fix it in the future?

Yes!

We've had trouble investigating this issue due to the whitelisting problem on our EWS bots. I am very hopeful that we will have that resolved today or tomorrow, at which point we can figure out what's going on here.

I have attempted to reproduce this build failure locally, and find that if I do a full rebuild, or delete my entire Windows build output directory and build, that I have NO PROBLEMS.

It's very frustrating. :-(

any update?

[Csaba Osztrogonác]

ping?

[Alexey Proskuryakov]

This is being worked on. Several other problems affecting Windows EWS got fixed in the meanwhile, including a networking setup issue and bug 147636.

[Csaba Osztrogonác]

It is already fixed.
