Thread: Three Regression Test Problems involving dates

Three Regression Test Problems involving dates

From
"Duncan Kinder"
Date:
Set forth below are three regression test failures encountered on RedHat
6.0.  All involved differences between expected and actual dates.  The
actual date is the date the test was run:

If PostgreSQL failed to compile on your computer or you found a bug that
is likely to be specific to one platform then please fill out this form
and e-mail it to pgsql-ports@postgresql.org.

To report any other bug, fill out the form below and e-mail it to
pgsql-bugs@postgresql.org.

If you not only found the problem but solved it and generated a patch
then e-mail it to pgsql-patches@postgresql.org instead.  Please use the
command "diff -c" to generate the patch.

You may also enter a bug report at http://www.postgresql.org/ instead of
e-mail-ing this form.

I see no date problems there.  Are you mistaking the diff headers for
data differences?

Anyway, the exp/pow problems are probably the result of a known
configuration glitch: if finite() is a function rather than a macro
on your machine, then 6.5.* doesn't do overflow testing correctly for
these two functions.  The polygon diffs look like just the usual
cross-machine differences in floating-point roundoff error, and the
random diff is, well, random.  (Run it again and it probably won't
fail.)

In short, nothing to worry about here.
