1. Modify dates-list definition
instead of either (list date0 date1 date) or
(list (list start0 end0 '())
(list start1 end1 '()) ...)
it now is a list-of-dates (list date0 date1 date2)
2. Pre-generate account-balances using dates-list.
account-balances-alist is an alist-of-balances
3. Use the pre-generated account-balance-alist instead of
calling (get-balance) to obtain balances. This
bypasses (get-balance) which calls a very expensive query-based
functions for every *account* and *date-interval*
This is neater. Split into 2 functions, both of which are useful
(monetaries-add . monetaries)
add different gnc-monetary objects into a gnc-commodity-collector
(monetaries+ . monetaries)
special case for above whereby all monetaries are expected to be in
one currency only -- convert gnc-commodity-collector to monetary
(gnc:account-get-balances-at-dates) is upgraded to
report-utilities. this function is slightly different to its
single-account counterpart because it does not retrieve subaccount
amounts.
I think this (gnc:account-get-balance-at-date) is flawed in sub-acct handling.
Consider account structure:
Assets [USD] - bal=$0
Bank [USD] - bal=$100
Broker [USD] - bal=$200
Cash [USD] - bal=$800
Funds [FUND] - bal=3 FUND @ $1000 each = $3000
- Calling (gnc:account-get-balance-at-date BANK TODAY #f) returns 100
- Calling (gnc:account-get-balance-at-date BROKER TODAY #f) returns 200
- Calling (gnc:account-get-balance-at-date BROKER TODAY #t) returns 1000
this is because although it counts all subaccounts bal $200 + $800 + 3FUND,
it retrieves the parent account commodity USD $1000 only.
It needs to be deprecated.
I think (gnc:account-get-balance-at-date) is flawed. It is actually
unused, so, it should be safe to remove. It needs to be deprecated.
Reports use xaccAccountGetBalanceAsOfDate instead, which does not
retrieve sub-acct balances.
