Neil Conway bca0383f9a Update installation docs for PL/Python to note that distutils is now
required. Original patch from James William Pye, editorializing by
Neil Conway.

Tom Lane 9fcbe2af11 Arrange for hash join to skip scanning the outer relation if it detects
that the inner one is completely empty.  Per recent discussion.  Also some
cosmetic cleanups in nearby code.

Tom Lane 5d9f5c20dd Issue a CHECKPOINT just after creating the regression database. Without
this, it's hard to debug core-dump test failures, because WAL replay will
enthusiastically remove the core file (along with the rest of the
regression database directory).  Per recent discussion, not to mention
bitter experience.

Tom Lane bebaf70613 Adjust ExecMakeTableFunctionResult to produce a single all-nulls row
when a function that returns a single tuple (not a setof tuple) returns
NULL.  This seems to be the most consistent behavior.  It would have
taken a bit less code to make it return an empty table (zero rows) but
ISTM a non-SETOF function ought always return exactly one row.  Per
bug report from Ivan-Sun1.

or two.

Neil Conway a3c53c834f This patch from Alvaro Herrera adds transaction ID to the list of
log_line_prefix escapes. The escape sequence used for this is %x.
%x previously meant "postmaster et al. stop here" -- this has been
renamed to %q.

Neil Conway 665d3736fb Clarify TODO item: we ought to implement updatable views per SQL99, not
SQL92 (the former defines a much more ambitious subset of views that
need to be updatable).

Tom Lane 95f20b96d4 Rotate on time boundaries that are sensible per local time rather than GMT.
Also, avoid truncating the file we just wrote into, which might otherwise
easily happen at DST boundaries.  Ed L. and Tom Lane.

Tom Lane 6da0c439ee Change some of the existing plpgsql regression test cases so that they
exercise dollar quoting and named function parameters.  AFAICS we had
no tests of either feature before.
2004-09-20 23:00:12 +00:00
Tom Lane 2f48836b1f Some editorializing on the docs for the dollar-quoting feature: fix
grammar, don't drop discussions into the middle of unrelated discussions,
etc.

Tom Lane 5b564e5307 Fix some shortcomings in psql's autocommit-off mode concerning detection
of commands for which a transaction block should not be forced.  Recognize
VACUUM and other PreventTransactionChain commands; handle nested /* .. */
comments correctly; handle multibyte encodings correctly.
Michael Paesold with some kibitzing from Tom Lane.

Tom Lane 768b647ead Now that I look, table 8-1 has some other marginal misstatements in it.
If we're going to put brackets around optional precision specs in some
entries, we'd better do it in all.

Neil Conway f6279e9ed7 Minor documentation cleanup and improvement. 2004-09-20 00:04:19 +00:00
Tom Lane fa8eb8a726 Add defenses against plpython functions being declared to take or return
pseudotypes.  Not sure why I neglected to add these checks at the same
time I added them to the other PLs, but it seems I did.

Tom Lane 84c7cef5eb Fix estimate_num_groups to be able to use expression-index statistics
when there is an expressional index matching a GROUP BY item.

Peter Eisentraut 915351e9c7 Add support for GNU/Hurd and GNU/*BSD. For our purposes, they behave just

Tom Lane a5713ec427 Hashed LEFT JOIN would miss outer tuples with no inner match if the join
was large enough to be batched and the tuples fell into a batch where
there were no inner tuples at all.  Thanks to Xiaoyu Wang for finding a
test case that exposed this long-standing bug.
2004-09-17 18:28:53 +00:00
Tom Lane 054b78ba38 Now that xmax and cmin are distinct fields again, we should zero xmax when
creating a new tuple.  This is just for debugging sanity, though, since
nothing should be paying any attention to xmax when the HEAP_XMAX_INVALID
bit is set.

Tom Lane 9f6df6c4a6 Fix oversight: there's no reason for PG_TRY to use sigsetjmp(buf,1)
since we don't change the signal mask during normal backend operations.
Use sigsetjmp(buf,0) to avoid many unnecessary kernel calls.

Tom Lane 257cccbe5e Add some marginal tweaks to eliminate memory leakages associated with
subtransactions.  Trivial subxacts (such as a plpgsql exception block
containing no database access) now demonstrably leak zero bytes.
2004-09-16 20:17:49 +00:00
Tom Lane 86fff990b2 RecentXmin is too recent to use as the cutoff point for accessing
pg_subtrans --- what we need is the oldest xmin of any snapshot in use
in the current top transaction.  Introduce a new variable TransactionXmin
to play this role.  Fixes intermittent regression failure reported by
Neil Conway.
2004-09-16 18:35:23 +00:00
Tom Lane 8f9f198603 Restructure subtransaction handling to reduce resource consumption,
as per recent discussions.  Invent SubTransactionIds that are managed like
CommandIds (ie, counter is reset at start of each top transaction), and
use these instead of TransactionIds to keep track of subtransaction status
in those modules that need it.  This means that a subtransaction does not
need an XID unless it actually inserts/modifies rows in the database.
Accordingly, don't assign it an XID nor take a lock on the XID until it
tries to do that.  This saves a lot of overhead for subtransactions that
are only used for error recovery (eg plpgsql exceptions).  Also, arrange
to release a subtransaction's XID lock as soon as the subtransaction
exits, in both the commit and abort cases.  This avoids holding many
unique locks after a long series of subtransactions.  The price is some
additional overhead in XactLockTableWait, but that seems acceptable.
Finally, restructure the state machine in xact.c to have a more orthogonal
set of states for subtransactions.
