I've got problems with other Python implementations too. E.g. try to run https://www.wikifunctions.org/view/en/Z19943 with the input 0.1234

I nudged a similar one with issues, and now all tests fail: https://www.wikifunctions.org/view/en/Z19933

I've raised a different ticket, T406848, for the wider Python issues in case they're different.

Similar issue with simplified Type object from Type (Z28945). I made a material change to its (then) single implementation (Z28947) to return a Quote object, timed at 19:58. When trying to add a test case the following morning, the actual result is not a Quote object:

An equivalent call from “Try this…” does return a Quote object:

This is not a cached function call. What is happening is that a previous version of the code is being picked up and used for a new function call, but only when executed in a test case in edit mode. I believe this accounts for the previous erratic behaviour: Z28720 was being evaluated using a previous version of the code, until it was published, when it used the current version. The subsequent failures were probably just the Python outage.

Quite apart from the frustrating inability to create new test cases reliably, it may well be that Z28947 didn’t need to change in the first place. It was performing as expected when using “Try this…” in edit mode and I assumed it was a de-referencing issue when I started getting a full type rather than a reference for new test cases. This seems to be confirmed by new implementation Z28967 which (so far) is behaving as expected.

Similar issue with (Integer, Rational number), quoted (Z29165): correct version of the code is used everywhere except when editing the test case.

At 13:50 (code was changed to expect
Z29128K1 at 12:46)…

Error type: Error in evaluation
Error data:
function call: "Z29128() got an unexpected keyword argument 'Z29128K1'"
Validation error type: Argument value error
Expected result: ["Z99",{"Z1K1":"Z99","Z99K1":"Z16683"},{"Z1K1":"Z99","Z99K1":"Z19677"}]
Actual result: Z24

Error persists at 18:23

I had a slightly different manifestation recently. this was failing in edit mode. It passed as soon as it was published but went back to failing again after visiting the function page, where it showed as passing… it may be that the 22:44 edit on the test case caused the reversion.

Any chance of an update on this one, please? Is the time taken for the system to fix itself predictable?

It looks like this is no longer limited to test-case editing. I changed Z32879 at 15:15 yesterday and the previous version of the implementation is still being used for new function calls and only works correctly when editing. This is the reverse of the original problem and much more disruptive.

Good luck with this one @gengh please don't hesitate to ask the community if we can help in any way 🙌
