4.2.0 regression : basic query using 'in' keyword working 4.1.11 and returning no result in 4.2.0

[jbrazeau]

I've upgraded alasql (4.1.10 -> 4.2.0) this morning and faced a regression.

I've isolated the problem in a trivial test available in the following git repository : https://gitlab.com/jean-francois.brazeau/alasql-bug-4.2.0

The repository contains a very basic test that :

• creates a simple table (2 columns)
• insert two rows
• selects the rows using in keyword

Simply run :

• go-4.1.11.sh to install alasql@4.1.11 and successfully run the test.
• go-4.2.0.sh to install alasql@4.2.0 and notice that the query returns no result at the end of the script.

Performance improvements yesterday were indeed affecting IN and NOT IN, so it seems something was missed in the unit test coverage.
I did add a similar test though, so not sure what causes it yet. I might investigate next week.

Probably related to using ? as using direct data assignments worked in the unit test.

@jbrazeau i have been able to reproduce and confirmed that my PR is indeed causing the regression.
I will let you know once i have a fix.

@jbrazeau see related PR which should fix it.

Thank you very much for paying attention to that issue.

I've checked out the PR, built alasql and manually "patched" dist/alasql.fs.js in my node_modules folder (after having installed alasql@4.2.0). I confirm that the regression seems to disappears ! 👍

I would propose merging this and release as 4.2.1.
We can check to re-add the cache layer for the Set later, now we have added more unit test coverage.

Released as part of 4.2.1
