[webkit-dev] Qt buildbot help

[Adam Barth]

I'm having trouble getting the Qt build bots to compile again after
moving JavaScriptCore into Source.  They don't seem to realize that
PLATFORM(QT) should be defined.  I suspect they might just need a
clobber, but I'm not sure how to do that via build.webkit.org.  I'd be
much obliged if someone with a Qt build and/or access to the buildbot
would lend me a hand.

Thanks!
Adam

Re: [webkit-dev] Newbie question re: raw bitmaps

[Brian Hoary]

*I feel I should point out here, that as far as I understand there is no
particular patent issue with Jpeg-XR. Microsoft have included Jpeg-XR under
their community promise program which is a legal promise not to sue anyone
for using patents they own for implementing a Jpeg-XR codec. The issue
mentioned in the bugzilla entry is not a patent problem. The problem is with
the reference code that Microsoft released for implementing a Jpeg-XR codec.
The licencing of which states the code can only be used to create/decode
images conforming to the Jpeg-XR spec. This condition makes the code non GPL
compatible. There is nothing stopping anyone from creating a GPL compatible
Jpeg-XR codec from scratch though.*

[webkit-dev] git and svn out of sync?

[Robert Hogan]

Hi,

I committed http://trac.webkit.org/changeset/74869 from a git-svn checkout. 

The change hasn't propagated to git.webkit.org for some reason.

My git-svn copy is set up to point directly to refs/remotes/origin/master 
per the recommendation in:

https://trac.webkit.org/wiki/UsingGitWithWebKit#Updating

I landed the commit with:

Tools/Scripts/webkit-patch --ignore-builders --git-commit=HEAD land

and encountered no errors:

rob...@mwenge:~/Development/WebKit$ Tools/Scripts/webkit-patch --ignore-
builders --git-commit=HEAD land
[webkit.py autoinstall messages snipped]
Parsing ChangeLog: /home/robert/Development/WebKit/Tools/ChangeLog
No bug id provided and --reviewer= not provided.  Not updating ChangeLogs 
with reviewer.

No bug id provided.

Hopefully no-one else commits before this becomes too difficult to repair..

Let me know if I can provide any more clues.

Thanks,
Robert

Re: [webkit-dev] git and svn out of sync?

[Robert Hogan]

Looks like this was a false alarm. The revision is now in git. 

It took an awfully long time to sync though. Was there a problem, or does 
the git repo wait for a minimum number of revisions before sync'ing?
