csun5285 opened a new pull request, #67431:
URL: https://github.com/apache/doris/pull/67431
NaN and infinity are recorded in the has_nan/has_positive_inf/
has_negative_inf flags and never move min/max, so a page holding nothing else
leaves both at the values add_values() starts from: min = DBL_MAX and max =
-DBL_MAX. Those are written out as if they were data, and the flags stand in
for at most one side, so reading them back reports a DBL_MAX that is nowhere in
the page -- SELECT MIN(v) answers with it while SELECT COUNT(*) WHERE v = that
value answers 0. On data written before 4.0 there is no flag at all and both
bounds are used, which prunes the page away: 25 rows of NaN return 0 for WHERE
v > 5.
The bounds round-trip exactly, so neither the flags nor the parse failure
#67341 keys on can tell such a zone map from a sound one. Mark it pass_all when
the bounds come back reversed, which only FLOAT and DOUBLE can do -- any value
of any other type moves both. Do the same in flush() and finish() so newly
written pages and segments record that they have no bounds instead of leaving
it to the reader.
