789a5b340c Move attached to shared memory out into a separate function for clarity. 2003-05-08 19:17:07 +00:00

075a0078df I think we're done with protocol instability, so mark server and libpq
as speaking the one true 3.0 protocol.

c0a8c3ac13 Update 3.0 protocol support to match recent agreements about how to
handle multiple 'formats' for data I/O.  Restructure CommandDest and
DestReceiver stuff one more time (it's finally starting to look a bit
clean though).  Code now matches latest 3.0 protocol document as far
as message formats go --- but there is no support for binary I/O yet.

137b123fc7 Fixed bug with Warnings. Warnings are not added to the Statement instead of
the connection when appropriate.
This checkin also adds the type map for jdbc3, however currently it is
identical to the jdbc2 mapping.

755d191700 Add display of eventual result RowDescription (if any) to the output
of Describe on a prepared statement.  This was in the original 3.0
protocol proposal, but I took it out for reasons that seemed good at
the time.  Put it back per yesterday's pghackers discussion.

8f6a6b7e9a Ensure that an Execute operation can't send tuples in cases where
Describe would claim that no tuples will be returned.  Only affects
SELECTs added to non-SELECT base queries by rewrite rules.  If you
want to see the output of such a select, you gotta use 'simple Query'
protocol.

79913910d4 Restructure command destination handling so that we pass around
DestReceiver pointers instead of just CommandDest values.  The DestReceiver
is made at the point where the destination is selected, rather than
deep inside the executor.  This cleans up the original kluge implementation
of tstoreReceiver.c, and makes it easy to support retrieving results
from utility statements inside portals.  Thus, you can now do fun things
like Bind and Execute a FETCH or EXPLAIN command, and it'll all work
as expected (e.g., you can Describe the portal, or use Execute's count
parameter to suspend the output partway through).  Implementation involves
stuffing the utility command's output into a Tuplestore, which would be
kind of annoying for huge output sets, but should be quite acceptable
for typical uses of utility commands.

2cf57c8f8d Implement feature of new FE/BE protocol whereby RowDescription identifies
the column by table OID and column number, if it's a simple column
reference.  Along the way, get rid of reskey/reskeyop fields in Resdoms.
Turns out that representation was not convenient for either the planner
or the executor; we can make the planner deliver exactly what the
executor wants with no more effort.
initdb forced due to change in stored rule representation.

94a3c60324 Ditch ExecGetTupType() in favor of the much simpler ExecGetResultType(),
which does the same thing.  Perhaps at one time there was a reason to
allow plan nodes to store their result types in different places, but
AFAICT that's been unnecessary for a good while.

20aea2ec7b Alter plpgsql's lexer so that yylineno and yymore are not used. This
avoids 'input buffer overflow' failure on long literals, improves
performance, gives the right answer for line position in functions
containing multiline literals, suppresses annoying compiler warnings,
and generally is so much better I wonder why we didn't do it before.

16503e6fa4 Extended query protocol: parse, bind, execute, describe FE/BE messages.

50ed78b805 Allow 60 in seconds fields of timestamp, time, interval input values.
Per recent discussion on pgsql-general, this is appropriate for spec
compliance, and has the nice side-effect of easing porting from old
pg_dump files that exhibit the 59.999=>60.000 roundoff problem.

ac5fdea687 When a TIMESTAMP, TIME, or INTERVAL precision is specified larger than our
implementation limits, do not issue an ERROR; instead issue a NOTICE and use
the max supported value.  Per pgsql-general discussion of 28-Apr, this is
needed to allow easy porting from pre-7.3 releases where the limits were
higher.

Unrelated change in same area: accept GLOBAL TEMP/TEMPORARY as a synonym
for TEMPORARY, as per pgsql-hackers discussion of 15-Apr.  We previously
rejected it, but that was based on a misreading of the spec --- SQL92's
GLOBAL temp tables are really closer to what we have than their LOCAL ones.

228697179a Fix erroneous space calculation leading to core dump in dumpProcLangs,
per report from Olivier Prenant.  Also fix off-by-one space calculation
in ReadToc; this woould not have hurt us until we had more than 100
dependencies for a single object, but wrong is wrong.

5295fffc26 Patch to fix up LONGVARBINARY support submitted by Amit Gollapudi
(agollapudi@demandsolutions.com).
Also applied the RefCursor support patch by Nic Ferrier.  This patch allows
you too return a get a result set from a function that returns a refcursor.
For example:
call.registerOutParameter(1, Types.OTHER);
call.execute();
ResultSet rs = (ResultSet) call.getObject(1);

de28dc9a04 Portal and memory management infrastructure for extended query protocol.
Both plannable queries and utility commands are now always executed
within Portals, which have been revamped so that they can handle the
load (they used to be good only for single SELECT queries).  Restructure
code to push command-completion-tag selection logic out of postgres.c,
so that it won't have to be duplicated between simple and extended queries.
initdb forced due to addition of a field to Query nodes.

1940434f1e Repair sloppiness about where cached mergeclause pathkeys are allocated.
Without this fix, CVS tip dumps core when running the regression tests
with geqo_threshold = 2.  I would think that a similar patch might be
needed in 7.3, but cannot duplicate the failure in that branch --- so
for now, leave well enough alone.

0c57d69dd7 Update to describe new set of globally-known contexts planned for support
of extended query features in new FE/BE protocol.  TransactionCommandContext
is gone (PortalContext replaces it for some purposes), and QueryContext
has taken on a new meaning (MessageContext plays its old role).

aa282d4446 Infrastructure for deducing Param types from context, in the same way
that the types of untyped string-literal constants are deduced (ie,
when coerce_type is applied to 'em, that's what the type must be).
Remove the ancient hack of storing the input Param-types array as a
global variable, and put the info into ParseState instead.  This touches
a lot of files because of adjustment of routine parameter lists, but
it's really not a large patch.  Note: PREPARE statement still insists on
exact specification of parameter types, but that could easily be relaxed
now, if we wanted to do so.
