Bugfixes
This is a complete list of the merged pull requests.
Fix Policy announcements not working when connection is using namespace filtering
Ditto 3.5.3 contained an optimization for Ditto internal pub/sub using namespace filtering.
This however did not take into account Policy announcements which was reported in
issue #1920 for which PR #1921 provides a fix.
Fix weak eTag handling of If-Match and If-None-Match headers
The conditional request headers If-Match and If-None-Match did not handle
“weak” eTags correctly - they always assumed strong eTags for If-Match and weak etags for If-None-Match.
This was fixed in PR #1924.
Fix nested lookup of tm:refs in WoT model extension resolving
PR #1923 fixes a bug when in the WoT integration a
ThingModel referenced another ThingModel which again referenced another one using tm:ref.
This kind of “nested” lookup lead to a parsing error - which was fixed.
Helm Chart
The Ditto Helm Chart contained some configuration bugs and enhancements which are also addressed with this bugfix release.
Adding Helm gateway option for token-integration-subject
In PR #1912 a new Helm configuration was added in order to configure
the environment variable OAUTH_TOKEN_INTEGRATION_SUBJECT for Ditto’s gateway service.
Add support to use kubernetes secrets for basicAuthUsers passwords
In PR #1913 the Helm chart was enhanced to use existing k8s secrets for obtaining usernames and passwords for authenticating users via nginx using basic auth.
# existingSecret contains the name of existing secret containing user and password
# format: ${user}:${password}, where secret key is ${user} and value is ${password}
# example creating secret for users ditto and jane:
# kubectl create secret generic ditto-basic-auth --from-literal ditto=ditto --from-literal jane=janesPw
Fix issues with trailing slash on ui and apidoc
PR #1916 fixes accessing the Ditto UI and apidocs when not adding a trailing slash.
