rebuilding daily summary on weewx database is not working, hopefully someone
can help
in the leadup to this,
* i copied producton weewx.sdb to dev/test (different host) weewx-gw1000.sdb,
* in which i dropped lots of columns and renamed others (using wee_database
—drop-columns and —rename-column respectively)
* then i dropped daily summaries (using wee_database —drop-daily).
* when i try to rebuild daily summaries (using wee_database —rebuild-daily), it
reports a failure that a daily table already (still) exists - this table
corresponds to a column that i did *not* alter
before doing —drop-daily i also deleted the content of a number of columns
(obviously not the dropped ones) using sql clause of form ‘update table set
altimeter = NULL, heatindex = NULL;’, preparatory to doing a —calc-missing
after some new values were to be loaded into core columns such as outTemp and
outHumidity
(presumably i can do an sql dump of archive table and reload to new db instance
and go forward with that, but i should work through this in case there is an
underlying weewx problem)
weewx-gw1000.conf points to weewx-gw1000.sdb
i am running another instance of weewx on the test system, from weewx-iwx.conf,
which points to weewx-iwx.sdb, obviously doing other things
details of commands and log follow
