XP Home or Pro? What version of Cygwin?
XP-HE. I ran a cygwin upgrade last night (to pick up the latest bison and get cygutils - it picked up gcc along the way). Then I installed the ipc-daemon2 as a service and started it, and ran make check.
gives these
tablecmds.c:3528: warning: dereferencing type-punned pointer will break
strict-aliasing rules
[snip]
FWIW, I saw warnings I never saw before when compiling Python under
Cygwin gcc 3.3.1 yesterday. I presume gcc 3.3.1 is pickier or more
"chatty" than it was before. Anyway, Python still passed its full
regression test.
Right. It's been sen on other platforms with the latest gcc too, I believe. As I understand the latest versions of gcc turn this on with -O2, so perhaps we need to add -fno-strict-aliasing as a short term measure if we are using gcc. But it should be fixed - IIRC the Linux kernel folks went through some agony over this and eventually made almost the whole kernel type-pun safe. After all, this enables better optimisation.
make check fails (hangs) consistently on parallel tests
Are you getting hangs or connection refused errors. The Cygwin
PostgreSQL README documents the following issue:
hangs - I have to kill the psql process to continue.
1. make check can generate spurious regression test failures due to overflowing the the listen() backlog queue which generates connection refused errors. Note that make installcheck does not have this problem since it runs all tests sequentially instead of in large concurrent groups.
max_connections set to 100, shared_buffers set to 1000 by initdb (CVS
version, not mine).
The above will not have any affects under Cygwin. IIRC, the listen() backlog is 200 under server versions of Windows (e.g., 2000 Advanced Server) and 5 on all other versions (e.g., XP Pro).
Can you try make installcheck instead?
will do tonight after work.
cheers
