Subject: pgsql: Add a test module for Bitmapset

Message-ID: <E1v0bON-001uYi-27@gemulon.postgresql.org> (raw)
Add a test module for Bitmapset
Bitmapset has a complex set of APIs, defined in bitmapset.h, and it can
be hard to test edge cases with the backend core code only.
This test module is aimed at closing the gap, and implements a set of
SQL functions that act as wrappers of the low-level C functions of the
same names. These functions rely on text as data type for the input and
the output as Bitmapset as a node has support for these. An extra
function, named test_random_operations(), can be used to stress bitmaps
with random member values and a defined number of operations potentially
useful for other purposes than only tests.
The coverage increases from 85.2% to 93.4%. It should be possible to
cover more code paths, but at least it's a beginning.
