How to apply patch to source files?

[Taytoo]

Received the email about HTTP2 related security patch. I build Qt 5.15.17 from sources and use Visual Studio. How do I apply the patch to the source files?

Solution: If you have git installed, its actually very easy using the git cli. Qt sources don't even need to be added to version control for this.

1. Open Terminal and Go to the Qt module the patch is for. E.g. the recent HTTP related patch is for QtBase, so go to that folder qtbase.
2. Type command "git apply <patch-filename> -v" (-v is just so you can see the output)

That's it!

Using patch command.
On Linux see "man patch" for details (or https://www.man7.org/linux/man-pages/man1/patch.1.html).

@jsulm I'm on Windows and it doesn't have patch command.
