pre-7.3 pg_dump archive files: namespace isn't there, and in some cases
te->tag may already be quotified. Per report from Alan Pevec and
followup testing.
pass if "default_with_oids" is set to false. I took the approach of
explicitly adding WITH OIDS to the CREATE TABLEs where necessary, rather
than tweaking the default_with_oids GUC var.
to a refcursor declaration are specified. This is a minimally-invasive fix
for the buffer overrun -- a more thorough cleanup will be checked into
HEAD.
per Andrew Dunstan. Also, don't override the user's value of PGHOST
in the 'make installcheck' case. I think the latter was an ill-considered
workaround for the Windows code back when libpq didn't properly default
to localhost on Unix-socket-less platforms.
MemoryContextAllocZero back to MemoryContextAlloc, same as it was in 7.4.
The zeroing is unnecessary since all the meaningful fields are filled in
just below. I had made it do that out of neatnik-ism, but some testing
with an example provided by Pavel Stehule showed that the zeroing was
accounting for about 5% of the runtime in a compute-intensive plpgsql
function. That seems a bit high of a price for neatnik-ism...
got it wrong when the JOIN was in an outer query level. Per example from
Laurie Burrow. Also fix same issue in markTargetListOrigin. I think the
latter is only a latent bug since we currently don't apply markTargetListOrigin
except at the outer level ... but should do it right anyway.
CASE 'a' WHEN 'a' THEN 1 ELSE 2 END. This worked in 7.4 and before
but had been broken due to premature freezing of the type of the test
expression. Per gripe from GÄbor SzÃcs.
few 'listen_addresses' as possible --- on most systems, none at all,
just the Unix socket. This avoids spurious check failures due to bogus
DNS setups, and is probably a good idea from a security standpoint anyway.
Per trouble report from Jean-GÅrard Pailloncy.
so that we can get the size of a shared inval message back down to what it
was in 7.4 (and simplify the logic too). Phase 2 of fixing the
'SMgrRelation hashtable corrupted' problem.
is the minimum required fix. I want to look next at taking advantage of
it by simplifying the message semantics in the shared inval message queue,
but that part can be held over for 8.1 if it turns out too ugly.
releases, a nonzero 'c' argument meant that the input string could be
terminated by either that character or \0. Recent refactoring broke
that, causing the thing to scan for 'c' only. This went undetected
because no part of the main code actually passes nonzero 'c'. However
it broke tsearch2 and possibly other user-written code that assumed
the old definition. Per report from Tom Hebbron.
request packet, use pqReadData(). This has the same effect since
conn->ssl isn't set yet and we aren't expecting more than one byte.
The advantage is that we will correctly detect loss-of-connection
instead of going into an infinite loop. Per report from Hannu Krosing.
discussion on pgsql-hackers-win32 list. Documentation still needs to
be tweaked --- I'm not sure how to refer to the APPDATA folder in
user documentation.
consistent. On Unix we now always consult getpwuid(); $HOME isn't used
at all. On Windows the code currently consults $USERPROFILE, or $HOME
if that's not defined, but I expect this will change as soon as the win32
hackers come to a consensus. Nothing done yet about changing the file
names used underneath $USERPROFILE.
subroutine that can hide platform dependencies. The WIN32 path is still
a stub, but I await a fix from one of the win32 hackers.
Also clean up unnecessary #ifdef WIN32 ugliness in a couple of places.
share lock on a buffer being written out before releasing BufMgrLock in
the BufferAlloc code path; if we do it later we might block on someone
who's re-pinned the buffer. I believe this is only an issue for BufferAlloc
and not the other places that call FlushBuffer. BufferSync must continue
to do it the old way since it may well be trying to write buffers that
other backends have pinned; but it should not be holding any conflicting
locks. FlushRelationBuffers is okay since it's got exclusive lock at the
relation level.
Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...
to shared memory as soon as possible, ie, right after read_backend_variables.
The effective difference from the original code is that this happens
before instead of after read_nondefault_variables(), which loads GUC
information and is apparently capable of expanding the backend's memory
allocation more than you'd think it should. This should fix the
failure-to-attach-to-shared-memory reports we've been seeing on Windows.
Also clean up a few bits of unnecessarily grotty EXEC_BACKEND code.
that is, files are sought in the same directory as the referencing file.
Also allow absolute paths in @file constructs. Improve documentation
to actually say what is allowed in an included file.
executable file isn't itself a symlink. We still need to run the
algorithm so that any directory symlinks in the path to the
executable are replaced by a true path. Noticed this on seeing
pg_config give me a completely wrong answer for --pkglibdir when
I called it through a symlink to the installation bindir.
the remainder of the current clog page during system startup. While
this was a good idea, it turns out the code fails if nextXid is
exactly at a page boundary, because we won't have created the "current"
clog page yet in that case. Since the page will be correctly zeroed
when we execute the first transaction on it, the solution is just to
do nothing when exactly at a page boundary. Per trouble report from
Dave Hartwig.
its presence. This amounts to desupporting Kerberos 5 releases 1.0.*,
which is small loss, and simplifies use of our Kerberos code on platforms
with Red-Hat-style include file layouts. Per gripe from John Gray and
followup discussion.
advancing ActiveSnapshot when we are inside a volatile function.
Per example from Gaetano Mendola. Add a regression test to catch
similar problems in future.
after an unknown or failed psql backslash command, and also while
discarding "extra" arguments of a putatively valid backslash command.
In the case of an unknown/failed command, make sure we discard the
whole rest of the line, rather than trying to resume at the next
backslash. Per discussion with Thomer Gil.
several reports of users being confused when they attempt to use ELSEIF
and run into trouble due to PL/PgSQL's lax parser. The parser will be
improved for 8.1, but we can fix most of the problem by allowing ELSEIF
for now.
silently ignored, allowing one to write bizarre things like
DECLARE x setof int;
in plpgsql. This has misled at least one novice into thinking that
plpgsql variables could be sets ...
thought there couldn't be any, but the folly of this was exposed by an
example from andrew@supernews.com 5-Dec-2004. The patch applies the
identical logic already used for table constraints and defaults to ON
SELECT rules, so I have reasonable confidence in it even though it might
look like complicated logic.
be emitted too soon. The previous code got this right in the case where
the CHECK was emitted as a separate ALTER TABLE command, but not in the
case where the CHECK is emitted right in CREATE TABLE. Per report from
Slawomir Sudnik.
Note: this code is pretty ugly; it'd perhaps be better to treat comments
as independently sortable dump objects. That'd be much too invasive a
change for RC time though.
