e0e7daef6d Lots of patches coming in from me today :-)
When drawing up a very simple "text-drawing" of how the negotiation is done,
I realised I had done this last part (fallback) in a very stupid way. Patch
#4 fixes this, and does it in a much better way.

Included is also the simple text-drawing of how the negotiation is done.

3114f92122 Add bsdi sparc port. 1999-09-27 00:48:42 +00:00
be09bc9ff2 Modify nodeAgg.c so that no rows are returned for a GROUP BY
with no input rows, per pghackers discussions around 7/22/99.  Clean up
a bunch of ugly coding while at it; remove redundant re-lookup of
aggregate info at start of each new GROUP.  Arrange to pfree intermediate
values when they are pass-by-ref types, so that aggregates on pass-by-ref
types no longer eat memory.  This takes care of a couple of TODO items...

40f6524161 Implement constant-expression simplification per Bernard
Frankpitt, plus some improvements from yours truly.  The simplifier depends
on the proiscachable field of pg_proc to tell it whether a function is
safe to pre-evaluate --- things like nextval() are not, for example.
Update pg_proc.h to contain reasonable cacheability information; as of
6.5.* hardly any functions were marked cacheable.  I may have erred too
far in the other direction; see recent mail to pghackers for more info.
This update does not force an initdb, exactly, but you won't see much
benefit from the simplifier until you do one.

95d3d468ce This is a patch for cygipc library provided by Yutaka Tanida.
This is necessary to prevent freezing in cygwin port.

e812458b27 Several changes here, not very related but touching some of the same files.
* Buffer refcount cleanup (per my "progress report" to pghackers, 9/22).
* Add links to backend PROC structs to sinval's array of per-backend info,
and use these links for routines that need to check the state of all
backends (rather than the slow, complicated search of the ShmemIndex
hashtable that was used before).  Add databaseOID to PROC structs.
* Use this to implement an interlock that prevents DESTROY DATABASE of
a database containing running backends.  (It's a little tricky to prevent
a concurrently-starting backend from getting in there, since the new
backend is not able to lock anything at the time it tries to look up
its database in pg_database.  My solution is to recheck that the DB is
OK at the end of InitPostgres.  It may not be a 100% solution, but it's
a lot better than no interlock at all...)
* In ALTER TABLE RENAME, flush buffers for the relation before doing the
rename of the physical files, to ensure we don't get failures later from
mdblindwrt().
* Update TRUNCATE patch so that it actually compiles against current
sources :-(.
You should do "make clean all" after pulling these changes.

f66393514f One last missing quoting bug in pg_dump:
now that sequence names are properly quoted for field defaults, mixed
case sequence names are generated. These are properly quoted in the
CREATE SEQUENCE lines, but not in the SELECT nextval lines, as per
below:

CREATE SEQUENCE "Teams_TeamID_seq" start 10 increment 1 maxvalue
2147483647 minvalue 1  cache 1 ;
SELECT nextval ('Teams_TeamID_seq');

This needs to be:
SELECT nextval ('"Teams_TeamID_seq"');

Patch included below.

dabc3f31b5 Fix for netmask('x.x.x.x/0') is 255.255.255.255 instead of 0.0.0.0
This is because (-1) << 32 is -1 (Only intel arc. has been checked)

fe2ab18ed9 Remove incorrect 'Assert(targetList != NULL)'. An
INSERT ... DEFAULT VALUES statement does indeed have a null targetlist,
at least during parse and rewrite stages.

e1a8b0f2ce Fix CASE bug identified by Keith Parks: CASE didn't reliably
treat a NULL condition result as FALSE.  Clean up some bogus comments
here and there, too.

f9f5dfbf10 Update regress test expected outputs for small changes in
error message wording, due to most cases of no-such-relation now being
detected in central heap_open code rather than on an ad-hoc basis.
1999-09-18 19:10:19 +00:00
bd272cace6 Mega-commit to make heap_open/heap_openr/heap_close take an
additional argument specifying the kind of lock to acquire/release (or
'NoLock' to do no lock processing).  Ensure that all relations are locked
with some appropriate lock level before being examined --- this ensures
that relevant shared-inval messages have been processed and should prevent
problems caused by concurrent VACUUM.  Fix several bugs having to do with
mismatched increment/decrement of relation ref count and mismatched
heap_open/close (which amounts to the same thing).  A bogus ref count on
a relation doesn't matter much *unless* a SI Inval message happens to
arrive at the wrong time, which is probably why we got away with this
sloppiness for so long.  Repair missing grab of AccessExclusiveLock in
DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi.
Recommend 'make clean all' after pulling this update; I modified the
Relation struct layout slightly.
Will post further discussion to pghackers list shortly.

You're right!

2ee735ca21 Allow ISOLATION and LEVEL as column names. These are SQL92 reserved words
which do not need to be so for our parser. Apparently omitted earlier.

f0f73b316d Allow CASE statement to contain *only* untyped result clauses or nulls.
Almost worked before, but forgot one place to check.
 Reported by Tatsuo Ishii.
Still does not do the right thing if inserting into a non-string target
 column. Should look for a type coersion later, but doesn't.

3ec5232363 Patch to cure O(N^2) behavior in libpq when reading a long
message under a kernel that only returns one packet per recv() call.  This
didn't use to matter much, but it starts to get annoying with multi-megabyte
EXPLAIN VERBOSE responses...
1999-09-13 03:00:19 +00:00
43d32d3683 First cut at doing something reasonable with OR-of-ANDs WHERE
conditions.  There are some pretty bogus heuristics in prepqual.c that
try to decide whether to output CNF or DNF format; they need to be replaced,
likely.  Right now the code is probably too willing to choose DNF form,
which might hurt performance in some cases that used to work OK.
But at least we have a foundation to build on.

b705fa3909 Make sure both SRCH_INC and SRCH_LIB are checked for existances and added to

2119cc0670 Further improvements in cnfify: reduce amount of self-recursion
in or_normalize, remove detection of duplicate subexpressions (since it's
highly unlikely to be worth the amount of time it takes), and introduce
a dnfify() entry point so that unintelligible backwards logic in UNION
processing can be eliminated.  This is just an intermediate step ---
next thing is to look at not forcing the qual into CNF form when it would
be better off in DNF form.
1999-09-12 18:08:17 +00:00
4644fc8071 Eliminate query length limitation imposed by pg_client_to_server
and pg_server_to_client.  Eliminate copy.c's restriction on the length
of a single attribute.
1999-09-11 22:28:11 +00:00
b65ab31910 Eliminate token length assumption in scanstr(). 1999-09-11 22:26:47 +00:00
b399805e22 Eliminate elog()'s hardwired limit on length of an error message.
This change seems necessary in conjunction with long queries, and it
cleans up some bogosity in connection with long EXPLAIN texts anyway.
Note that current libpq will accept any length error message (at least
until it runs out of memory); prior versions have a limit of 8K, but
will cleanly discard excess error text, so there shouldn't be any
big compatibility problems with old clients.

51db6455ea Repair error noticed by Roberto Cornacchia: selectivity code
was rejecting negative attnums as bogus, which of course they are not.
Add code to get_attdisbursion to produce a useful value for OID attribute,
since VACUUM does not store stats for system attributes.
Also, repair bug that's been in eqjoinsel for a long time: it was taking
the max of the two columns' disbursions, whereas it should use the min.
