I see a lot of these in the logs for the beta cluster:
Feb 9 07:19:58 deployment-mediawiki01: #012Catchable fatal error: Argument 3 to hash_hmac() must be of type ?string, bool given in /srv/mediawiki/php-master/includes/utils/MWCryptHash.php on line 108
Feb 9 07:20:09 deployment-mediawiki02: message repeated 6 times: [ #012Catchable fatal error: Argument 3 to hash_hmac() must be of type ?string, bool given in /srv/mediawiki/php-master/includes/utils/MWCryptHash.php on line 108]
| Subject | Repo | Branch | Lines +/- | |
|---|---|---|---|---|
| Throw an exception when the $key argument to hash_hmac is not a string | mediawiki/core | master | +4 -0 |
if this helps finding the cause, on commons.wikimedia.beta.wmflabs.org I'm seeing this, or a similiar error in the response body when calling the API via OAuth "Argument 3 to hash_hmac() must be of type ?string, bool given"
Does not seem to affect production (at least with the reproduction steps given in T130611), even though the same code should be live on group0 now.
