  1. Test of PG7.3.2b2 on SGI Irix

    Robert E. Bruccoleri <bruc@stone.congenomics.com> — 2002-10-31T15:35:11Z

    I've built and run the regression tests on PostgreSQL7.3 beta 2 on
SGI Irix and found the following suspicious compiler error message:

gmake[4]: Entering directory `/pg/postgresql-7.3b2/src/backend/utils/hash'
cc -64 -g -woff 1164,1171,1185,1195,1552 -I../../../../src/include -I/stf/sys64/include -I/stf/sys64/include/readline -U_NO_XOPEN4  -c dynahash.c -o dynahash.o
cc-1184 cc: WARNING File = dynahash.c, Line = 543
  "=" is used where where "==" may have been intended.

  		Assert(currBucket && !(saveState.currBucket = NULL));
  		^

Looks like a bug to me.

All the regression tests pass except for tests involving Savings Time
which are off by one hour. --Bob

No, the code is correct, although no doubt too clever by half :-(

Details?  If you ran it today then the DST-boundary problems shouldn't
be there anymore.

How can it be correct? If the assertion checking is turned off, then
saveState.currBucket will not be changed, but if assertion checking is
on, it will be set to NULL. The only way that it would make no
difference would be if the saveState.currBucket were NULL to begin
with, but then, why make the assignment?

If assertion checking is off (and the code is otherwise correct) then
there's no need to reset saveState.currBucket to NULL, or so at least
I interpret the author's intent.  Notice that an == test would be
completely redundant with the first part of the Assert, since the
local currBucket was just assigned from saveState.currBucket.  What
is really being accomplished here is equivalent to
		Assert(currBucket);
#ifdef USE_ASSERT_CHECKING
		saveState.currBucket = NULL;
#endif

However, it's a tad silly to confuse readers this much in order to save
one lousy store instruction, so I'm inclined to change it to
		Assert(currBucket);
		saveState.currBucket = NULL;
IIRC, you're not the first to look at that code and think it's wrong.

It looks like your files match the solaris-1947 variants; would you
confirm that?  If so, please send a patch with a resultmap addition
that matches your platform.  There is already an entry

horology/.*-irix6=horology-no-DST-before-1970

but it looks like that's not triggering on your system.

It's not the same as the solaris-1947 variants. I compared all three
horology files in the expected directory -- none match.  There is no
such irix6 file in the distribution.

Please let me know what else you'd like me to do WRT to this
diff. --Bob
