16 years agoFix some bugs introduced by the 8.2-era conversion of cube functions to V1
Tom Lane [Thu, 29 May 2008 18:46:40 +0000 (18:46 +0000)]
Fix some bugs introduced by the 8.2-era conversion of cube functions to V1
calling convention.  cube_inter and cube_distance could attempt to pfree
their input arguments, and cube_dim returned a value from a struct it
might have just pfree'd (which would only really cause a problem in a
debug build, but it's still wrong).  Per bug #4208 and additional code
reading.

In HEAD and 8.3, I also made a batch of cosmetic changes to bring these
functions into line with the preferred coding style for V1 functions,
ie declare and fetch all the arguments at the top so readers can easily
see what they are.

16 years agoAlter the xxx_pattern_ops opclasses to use the regular equality operator of
Tom Lane [Tue, 27 May 2008 00:13:09 +0000 (00:13 +0000)]
Alter the xxx_pattern_ops opclasses to use the regular equality operator of
the associated datatype as their equality member.  This means that these
opclasses can now support plain equality comparisons along with LIKE tests,
thus avoiding the need for an extra index in some applications.  This
optimization was not possible when the pattern opclasses were first introduced,
because we didn't insist that text equality meant bitwise equality; but we
do now, so there is no semantic difference between regular and pattern
equality operators.

I removed the name_pattern_ops opclass altogether, since it's really useless:
name's regular comparisons are just strcmp() and are unlikely to become
something different.  Instead teach indxpath.c that btree name_ops can be
used for LIKE whether or not the locale is C.  This might lead to a useful
speedup in LIKE queries on the system catalogs in non-C locales.

The ~=~ and ~<>~ operators are gone altogether.  (It would have been nice to
keep them for backward compatibility's sake, but since the pg_amop structure
doesn't allow multiple equality operators per opclass, there's no way.)

A not-immediately-obvious incompatibility is that the sort order within
bpchar_pattern_ops indexes changes --- it had been identical to plain
strcmp, but is now trailing-blank-insensitive.  This will impact
in-place upgrades, if those ever happen.

Tom Lane [Mon, 26 May 2008 18:54:29 +0000 (18:54 +0000)]
Fix an old corner-case bug in set_config_option: push_old_value has to be
called before, not after, calling the assign_hook if any.  This is because
push_old_value might fail (due to palloc out-of-memory), and in that case
there would be no stack entry to tell transaction abort to undo the GUC
assignment.  Of course the actual assignment to the GUC variable hasn't
happened yet --- but the assign_hook might have altered subsidiary state.
Without a stack entry we won't call it again to make it undo such actions.
So this is necessary to make the world safe for assign_hooks with side
effects.  Per a discussion a couple weeks ago with Magnus.

16 years agoAdjust timestamp regression tests to prevent two low-probability failure
Tom Lane [Sun, 25 May 2008 21:51:00 +0000 (21:51 +0000)]
Adjust timestamp regression tests to prevent two low-probability failure
cases.  Recent buildfarm experience shows that it is sometimes possible
to execute several SQL commands in less time than the granularity of
Windows' not-very-high-resolution gettimeofday(), leading to a failure
because the tests expect the value of now() to change and it doesn't.
Also, it was recognized some time ago that the same area of the tests
could fail if local midnight passes between the insertion and the checking
of the values for 'yesterday', 'tomorrow', etc.  Clean all this up per
ideas from myself and Greg Stark.

There remains a window for failure if the transaction block is entered
exactly at local midnight (so that 'now' and 'today' have the same value),
but that seems low-probability enough to live with.

Since the point of this change is mostly to eliminate buildfarm noise,
back-patch to all versions we are still actively testing.

Remove arbitrary 10MB limit on two-phase state file size. It's not that hard

schema with ~25000 objects. The really bogus thing about the limit was that
it was enforced when a state file file was read in, not when it was written,
