Public bug reported:
Hi,
We have nginx vhosts configured that worked for 5 years in a row, and then this
morning they crashed.
unattended upgrade to nginx 1.24.0-2ubuntu7.16
In a vhost:
if ($host ~* ([0-9]+)\.(.*?)\.(.*)) {
set $pullrequest $1;
set $repo $2;
Example URL https://1189.lib.prtest.example.org/gcovr/index.html
It should evaluate to:
pullrequest=1189
repo=lib
Today the result was:
pullrequest=1189
repo=1189
I fixed it locally with this patch. but the cause is unknown. it seems like a
bug was introduced.
- if ($host ~* ([0-9]+)\.(.*?)\.(.*)) {
- set $pullrequest $1;
- set $repo $2;
+ if ($host ~* "^(?<pullrequest>[0-9]+)\.(?<repo>[^.]+)\.(?<domain>.+)$") {
+ set $pullrequest $pullrequest;
+ set $repo $repo;
or, perhaps, tell me why the original code was faulty and needed to be modify
this way.
