The first three patches have been committed.
b4a132022 has had some not-so-desirable effects in the buildfarm:
drongo and hoatzin are each spewing a couple dozen repetitive
warnings about every bison-generated header file, eg
src/backend/bootstrap/bootparse.h(111): warning C4255:
'boot_yyparse': no function prototype given: converting '()' to '(void)'
Both of those machines are using bison 2.7, which is pretty old
and evidently isn't careful about generating complete prototypes.
I'm not sure if there's anything to be done about this, except
perhaps nag the animals' owners to find a newer bison somewhere.
We could revert b4a132022, but then we might miss valid warnings
about such issues in Windows-only code.
Let's try the nagging route.
I found it especially curious that hoatzin is a relatively new member,
so why is it running this ancient Bison version? Looking at the
Chocolatey packages:
https://community.chocolatey.org/packages?q=bison
it appears that
choco install winflexbison
gives you the old version, and you need
choco install winflexbison3
to get a newer version. So it seems easy to fall into that "trap" if
you don't pay attention.
So perhaps these buildfarm members could update their Bison version
sometime.
I found one mention of this command in our wiki
(https://wiki.postgresql.org/wiki/Meson#Windows), which I updated. If
we find any other documents or guides with these commands, we should
try to get them updated, too.
drongo is updated
cheers
