I pushed a commit with some documentation improvements. |
@sverker makes sense to me 👍 |
After discussion in erlang#6730 Changed `db_term_list_prepend*` to `db_term_list_append*` so values to be stored against a key have their order preserved. Previously due to building the linked list via prepending, the values insert order was reversed from OTP 23 onward.
Describe and warn about lots of objects with same keys in bag and duplicate_bag.

Expanded the test case to include provoking bug for @madlep Thanks for good report and fix. |
Since OTP 23, when inserting a list of values into an ets
bagtable, values for the same key are inserted in reversed order (prior to OTP 22, they were inserted in the order in the list).Implementing fix suggested by @sverker to build linked list of
DbTermvalues stored against a key by appending (rather than prepending as it had been doing).Fix for #6730 (see description there for code to reproduce + original correct behaviour on OTP 22, and regression behaviour on OTP >= 23)
