| 379 | Thanks for this patch. Probably we should use !isset() instead of empty() since:
In short, empty() also discards the string "0" and maybe is important here. | |||||||||||||||||||||||||||||||||||||

| 379 | thanks yep that makes sense. Im still pretty unaware of the quirks of php | |
looking at those failing test cases puppet-lint for my version puppet-lint 2.4.2 uses

xml linter seems to now specify a different column for one test

| 379 | At the moment the above line ↑ means this ↓ $severity_name = strtolower($match['severity'] ?? null); So, if somebody used idx() it means that this value can be undefined/NULL. So, before PHP 8.1 NULL was not a problem, since $severity_name was just casted to an empty string by strtolower(). In short this function probably must work even if $severity_name is an empty string "". | |
| 382 | Sorry if I propose another approach 🙈 Can we rollback violently and try the above one-line change instead? Does this make your day too? I propose this, since I'm not a Phorge maintainer and I don't 100% understand all the facets in this method. But, I can reasonably assume that the author used idx() for a reason: the author assumed that $match['severity'] can be undefined. So, that value can become NULL. So, NULL was passed to strtolower() and - before PHP 8.1 - that was good, and the problem is: now it's not. So we can just explicit a default valid value (an empty string, instead of a deprecated NULL), without changing any other logic and without implementing any new short-circuit, and just relying on the previous don't care strtolower('') logic. (Ideally, we would not call strtolower() with an empty string, but, again, it's probably a reasonable don't care there). I'm not bold enough to approve the previous change, but I will surely approve this patch using the idx($match, 'severity', '') since to me that is the exact minimal change to make PHP 8.1 happy, and gives to me a 100.0000% certainty that we will not introduce any regression (instead of 90%) - assuming that the code that was already there, already made sense. Thank you for your thoughts in this and for your precious help | |

| 382 | Sure thing that makes a lot of sense. | |
