Hi all,
Sometimes, when a backport request from master to an LTS release has merge
conflicts, the RM will ask for a new PR that fixes the merge conflicts. It’s
important that we all do these the same way, so here’s the outline on how I
think we should do these.
0) Make a branch off the LTS release you want to cherry-pick to (e.g. git
checkout -b LeifBackport 7.1.x).
1) Run “cherry-pick -x abcd1234”, the -x here is critical.
2) Resolve the merge conflicts, but retain the commit Subject and message body
as it was in the original commit.
3) Uncomment the section that specifies which files has merge conflicts. This
would include that as part of the commit message, see the example below.
4) Make the PR on Github.
5) If you have permissions, please make an effort to set the same Labels,
Assignees etc. Set the reviewer to the RM for the LTS that you are backporting
to. Add the Backport label as well, to make it clear that this was a backport
of a previous commit.
6) Set the Project to the LTS version (e.g. Project 7.x).
Now, don’t do this unless the RM has asked for it! You should still propose
potential backports on the original PR, that has been landed on the “master”
branch. You do this by adding the Project for the LTS version as well (e.g.
Project 7.x). The “rules” for back ports have not changed:
1) They should fix real issues/bugs
2) They must not break compatibility
3) If they add a new feature, they would get on the queue for a potentially
upcoming minor release (e.g. 7.2.x). The exception being if the new feature
(e.g. new configuration) is needed to fix a serious problem (typically a
security issue).
Cheers,

Proper support fort he %{URL:<qual>} conditions
This was never properly, or completely, implemented. This makes sure that
the URL conditions works as both conditions and values. Supported qualifiers
are e.g.
cond %{SEND_RESPONSE_HDR_HOOK} [AND]
cond %{CLIENT-URL:SCHEME} =http
set-header X-Url %{CLIENT-URL}
set-header X-Url-Scheme %{CLIENT-URL:SCHEME}
set-header X-Url-Host %{CLIENT-URL:HOST}
set-header X-Url-Port %{CLIENT-URL:PORT}
set-header X-Url-Path %{CLIENT-URL:PATH}
set-header X-Url-Query %{CLIENT-URL:QUERY}
set-header X-Url-Matrix %{CLIENT-URL:MATRIX}
