This is an automated email from the git hooks/post-receive script.
oec pushed a commit to branch master
in repository exchange.
The following commit(s) were added to refs/heads/master by this push:
new 571d43ce [WiP] added TALER_AMOUNT type to Postgres - first in
age_withdraw
571d43ce is described below
commit 571d43cef3732ed6f491d91a9e767a80008edeb1
Author: Özgür Kesim <oec-taler@kesim.org>
AuthorDate: Thu Jul 27 23:57:07 2023 +0200
[WiP] added TALER_AMOUNT type to Postgres - first in age_withdraw
- Added a type TALER_AMOUNT (val INT8, frac INT4) to Postgres.
- Added PLSQL functions/procedures
- amount_normalize(a)
- amount_add(a, b)
- amount_left_minus_right(l, r, diff, ok bool)
- Added PQ-helper functions
- TALER_PQ_query_param_amount_tuple()
- TALER_PQ_result_spec_amount_tuple()
- In table 'age_withdraw', changed fields 'amount_with_fee_val' and
'..._frac'
into single field 'amount_with_fee' be of type TALER_AMOUNT
- Changed functions/stored procedures 'do_age_withdraw' and
'get_age_withdraw' to use new APIs.
=> make check runs through without errors,
age-withdraw and -reveal test passes.
