[Qt] Find needed forwarding headers for WebKit2 automatically

• Component: Platform
• Status: RESOLVED FIXED

[Balazs Kelemen]

Our plan is to set the WebKit2 build in default ews and/or buildbot builds. The problem is that our build can break because of a single new included file. As I see this is not true for mac and win (they copy almost all WebCore header to the build dir). I want to use a more sophisticated solution: generate the list of the headers with a script and use the stdout of the script in the DerivedSources.pro.

Eric, could you clue me up about what is wrong with this patch? I have created it with svn-create-patch. Normally I am using git but I would have liked to create the new file with svn copy this time.

This may be an svn-apply regression.  CCing Dan.

I think this is an svn-apply regression.  Dan Bates is already CC'd.

This patch contains an svn:mergeinfo property change:
[[
Property changes on: WebKitTools/Scripts/enumerate-included-framework-headers
___________________________________________________________________
Added: svn:mergeinfo
   Merged /trunk/WebKitTools/Scripts/find-included-framework-headers:r53455
]]

I'm not familiar with this property. So far, from reading <http://svnbook.red-bean.com/nightly/en/svn-book.html#svn.branchmerge.basicmerging.mergeinfo> this property is used by SVN to "track changesets—that is, which changes have been merged to which branches".

svn-apply/svn-unapply do not support the svn:mergeinfo property. 

I'm currently trying to better understand svn merge/the svn:mergeinfo property.

[Balazs Kelemen]

Here is my use case:
   - creating the new file by "svn copy find-included-framework-headers enumerate-included-framework-headers"
   - editing the new file
   - creating the patch by "svn-create-patch", however svn diff has similar output

I am not familiar with merge logic of svn but it seems like this copy and edit use case is handled by the merginfo property.
I am going to land this with a git diff now if you do not mind.

Filed bug #45236 to add support to svn-apply/unapply for recognizing the svn:mergeinfo property and hence process patches that contain it.
