Bug 36477 – webkit-patch reads wrong bug url from unified diff context

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Hajime Morrita]

With "post-commits", webkit-patch can read wrong URL from "context" part of diff text

+        We expect https://bugs.webkit.org/show_bug.cgi?id=12345 to be found

           It found this http://webkit.org/b/67890 instead.

How to reproduce:

1. Checkout git.webkit.org tree
2. Ensure last changelog contains http://webkit.org/b/123 style bug  URL
3. make change, with changelog which containshttps://bugs.webkit.org/show_bug.cgi=456 style bug URL
4. try post-commits --dry for that change

Expected:
- the patch would be post for Bug 456
Actual:
- the patch is post for 123

A concrete example of such patch is https://bug-36338-attachments.webkit.org/attachment.cgi?id=51146

This is the wrong fix.  In this case you want to just use the code for pulling the bug from the ChangeLogEntry instead of the diff.  This proposed change would still wrongly grab bug urls added in other parts of the diff besides the ChangeLog.

I recently added a ChangeLogEntry class which exposes a bug_id() method which should fix this case.

Thank you for the fix attempt though!  I think we have at least one dup of this bug.

Thank you for reviewing quickly!

Agreed.

I couldn't find bug_id() on ChangeLogEntry. It looks not landed yet.
Would you tell me which bug contains that?
I'll watch it and retry this after its landing.

BTW, Bug 33471 and Bug 33197 looks similar. But I'm not sure.

I don't think it's right that commit_message_for_this_commit throws.  But that's an old mistake of mine.  Would be nice to have a FIXME in your try-catch, but this is fine as is.
