Neil Conway 3cc8661232 Remove support for libmhash/libmcrypt.
libmcrypt seems to dead, maintainer address bounces,
and cast-128 fails on 2 of the 3 test vectors from RFC2144.

So I see no reason to keep around stuff I don't trust
anymore.

Support for several crypto libraries is probably only
confusing to users, although it was good for initial
developing - it helped to find hidden assumptions and
forced me to create regression tests for all functionality.

Tom Lane ee4ddac137 Convert index-related tuple handling routines from char 'n'/' ' to bool
convention for isnull flags.  Also, remove the useless InsertIndexResult
return struct from index AM aminsert calls --- there is no reason for
the caller to know where in the index the tuple was inserted, and we
were wasting a palloc cycle per insert to deliver this uninteresting
value (plus nontrivial complexity in some AMs).
I forced initdb because of the change in the signature of the aminsert
routines, even though nothing really looks at those pg_proc entries...

Neil Conway fe7015f5e8 Change the return value of HeapTupleSatisfiesUpdate() to be an enum,
rather than an integer, and fix the associated fallout. From Alvaro

Tom Lane 354049c709 Remove unnecessary calls of FlushRelationBuffers: there is no need
to write out data that we are about to tell the filesystem to drop.
smgr_internal_unlink already had a DropRelFileNodeBuffers call to
get rid of dead buffers without a write after it's no longer possible
to roll back the deleting transaction.  Adding a similar call in
smgrtruncate simplifies callers and makes the overall division of
labor clearer.  This patch removes the former behavior that VACUUM
would write all dirty buffers of a relation unconditionally.

Bruce Momjian 683f60da3d Add mention of why malloc() has to be used in snprintf.c. 2005-03-20 13:54:53 +00:00
Bruce Momjian 8c72526fe9 Department of second thoughts. Remove FRONTEND from snprintf.c because
snprintf is called before the memory system is started.  We have to just
malloc/free.  There are no elogs in the code so we should be fine.

Bruce Momjian 83ebbfac75 Another change for FRONTEND snprintf.c. 2005-03-20 02:40:28 +00:00
Bruce Momjian 614fcbeba7 Mark snprintf.c as a file that uses FRONTEND and needs to a version in
the server-side port library.  Somehow I missed that change when I added
memory allocation to snprintf.c.

Tom Lane 91728fa26c Add temp_buffers GUC variable to allow users to determine the size

Tom Lane d65522aeb6 Upgrade localbuf.c to use a hash table instead of linear search to
find already-allocated local buffers.  This is the last obstacle
in the way of setting NLocBuffer to something reasonably large.

Tom Lane 88164799ce Need to reset local buffer pin counts, not only shared buffer pins,

Tom Lane 7a969cad2e Treat EPERM as a non-error case when checking to see if old postmaster
is still alive.  This improves our odds of not getting fooled by an
unrelated process when checking a stale lock file.  Other checks already
in place, plus one newly added in checkDataDir(), ensure that we cannot
attempt to usurp the place of a postmaster belonging to a different userid,
so there is no need to error out.  Add comments indicating the importance
of these other checks.

Neil Conway d344505d1b This patch moves some code for preprocessing FOR UPDATE from
grouping_planner() to preprocess_targetlist(), according to a comment
in grouping_planner(). I think the refactoring makes sense, and moves
some extraneous details out of grouping_planner().

Neil Conway d663d3ba3a This patch makes \d on tables and views sort fk constraints, triggers
and rules alphabetically in the output.  This makes it the same as
for indexes and stops the irritating random or reverse ordering it
currently has.

Bruce Momjian f402125926 Force initdb cause of encoding additions. 2005-03-16 22:59:42 +00:00
Tom Lane f97aebd162 Revise TupleTableSlot code to avoid unnecessary construction and disassembly
of tuples when passing data up through multiple plan nodes.  A slot can now
hold either a normal "physical" HeapTuple, or a "virtual" tuple consisting
of Datum/isnull arrays.  Upper plan levels can usually just copy the Datum
arrays, avoiding heap_formtuple() and possible subsequent nocachegetattr()
calls to extract the data again.  This work extends Atsushi Ogawa's earlier
patch, which provided the key idea of adding Datum arrays to TupleTableSlots.
(I believe however that something like this was foreseen way back in Berkeley
days --- see the old comment on ExecProject.)  A test case involving many
levels of join of fairly wide tables (about 80 columns altogether) showed
about 3x overall speedup, though simple queries will probably not be
helped very much.

I have also duplicated some code in heaptuple.c in order to provide versions
of heap_formtuple and friends that use "bool" arrays to indicate null
attributes, instead of the old convention of "char" arrays containing either
'n' or ' '.  This provides a better match to the convention used by
ExecEvalExpr.  While I have not made a concerted effort to get rid of uses
of the old routines, I think they should be deprecated and eventually removed.

Bruce Momjian 494f30c953 Prevent locale-aware handling of upper, lower, and initcap when the

Backpatch to 8.0.X because some operating systems were throwing errors
for such operations, rather than ignoring the locale when it was C.
