This PR reverts the timestamp work.
The timestamp work requires changes to FB and IDK; and there are
circular dependencies between tests in either repo preventing merging
of either. The work here is pretty stable, but required bypassing
the smoketest. Meanwhile, I found some additional things in IDK that
need addressing which means I merged this work in pre-maturely. Once
I get that worked out, I'll re-commit these commits.
This reverts following commits related to timestamp work:
bypass of smoke test b/c of circular dep with IDK: 0676790
update codec to reflect changes to timstamp range: bd5dc76
fix few bugs regarding timestamp: 33fce8a
increase time range for timestamp by using specified granularity: 5939923.
previously we allowed users to specify a granularity for timestamp
e.g. seconds, milli, micro, nano
however we converted everything to nano before we stored it.
This reduced the allowed range for all time units to what
was allowed by timestamp. For example, with second granularity
you can represent billions of years within the capacity of
int64 but with nano its somewhere b/w 100-200 years.
So now, for timeunits of seconds, milli, and micro the range
is year 0001 - 9999. These limits come from what Go
supports.
So this uses unit specific function to translate
timestamps to values and vice versa to increase
the time range.
* Revert "make pql.Decimal.Value a private big.Int field"
This reverts commit eab6174388.
* Revert "pql.Decimal for DecimalVal in ValCount&GroupCount"
This reverts commit a0c9eec410.
* Revert "Add AddDecimal support to pql"
This reverts commit 50787fd37a.
This ensures that we can't overflow when adding `pql.Decimal`s together. The
only place we can possibly overflow is when converting pql.Decimal to an Int64,
but that is a risk we have to take. Also, the only place we do this is in our
ToRowser. We could maybe change that to strings, so the presentation of data
doesn't indicate an overflow, but that is a later decision to make. It will
also involve fixing the generate-proto-grpc make command, because that's broken
rn.
i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
We want to distinguish different *kinds* of GroupCounts, so we're
making the GroupCounts parent object track its type so we can keep that
correct.
Adding this to protobuf, etc, then creates some weird behaviors
because sometimes we expect []GroupCount, and sometimes we expect
*GroupCounts. This implies changes to test cases. Also, the
changes to test cases imply that some test cases are probably now
wrong; for instance, they're expecting a "sum" column, equal to zero,
when no sum was requested.
We try to make the encoder handle a []*GroupCount gotten from another
node without panicing, and avoid breaking the semantics of the existing
messages, renumbering messages or components, etc.
Since a previous version, the `.Groups` member has been privatized,
and the `.Get()` convenience accessor has been renamed `.Groups()`
and is now used consistently in a way that should reduce the risk
of nil pointers causing crashes. Also, NewGroupCounts is used in
a couple more places.
