617f123f06 Get rid of retail definitions of HAVE_STRDUP and HAVE_VSNPRINTF in
some of the Windows-only makefiles; the correct place to assert these
things is pg_config.h.win32.  Per bug #2677.

d735804f88 Translate Windows' GMT Standard Time/GMT Daylight Time zones to
zic's Europe/London, rather than Europe/Dublin as before.  This seems
a less surprising choice, particularly with respect to dates before
1948.  Original suggestion was to translate to straight GMT, but this
seems wrong given that these zones *are* DST-aware.  Per offlist
discussion with Magnus.

7ec1c5a867 Prevent intratransaction memory leak when a subtransaction is aborted
in the middle of executing a SPI query.  This doesn't entirely fix the
problem of memory leakage in plpgsql exception handling, but it should
get rid of the lion's share of leakage.

5fc2d7e451 Suppress timezone (%Z) part of timestamp display when running on Windows,
because on that platform strftime produces localized zone names in varying
encodings.  Even though it's only in a comment, this can cause encoding
errors when reloading the dump script.  Per suggestion from Andreas
Seltenreich.  Also, suppress %Z on Windows in the %s escape of
log_line_prefix ... not sure why this one is different from the other two,
but it shouldn't be.

c714e5cba7 Fix plpython to work (or at least pass its regression tests) with
python 2.5.  This involves fixing several violations of the published
spec for creating PyTypeObjects, and adding another regression test
expected output for yet another variation of error message spelling.

3ad0728c81 On systems that have setsid(2) (which should be just about everything except
Windows), arrange for each postmaster child process to be its own process
group leader, and deliver signals SIGINT, SIGTERM, SIGQUIT to the whole
process group not only the direct child process.  This provides saner behavior
for archive and recovery scripts; in particular, it's possible to shut down a
warm-standby recovery server using "pg_ctl stop -m immediate", since delivery
of SIGQUIT to the startup subprocess will result in killing the waiting
recovery_command.  Also, this makes Query Cancel and statement_timeout apply
to scripts being run from backends via system().  (There is no support in the
core backend for that, but it's widely done using untrusted PLs.)  Per gripe
from Stephen Harris and subsequent discussion.

66eda1c7b3 VC build patch from Magnus:
Typo in the changes to plperl - uses wrong dir, and had a missing slash.

Also fixes error checking for xsubpp - it was broken in a way that hid
the problem above when run more than once (which is the normal case when
developing).

bcd713a618 If SSL negotiation fails and SSLMODE is 'prefer', then retry without SSL.
Negotiation failure is only likely to happen if one side or the other is
misconfigured, eg. bad client certificate.  I'm not 100% convinced that
a retry is really the best thing, hence not back-patching this fix for now.
Per gripe from Sergio Cinos.

150328cd61 I noticed that the Partitioning section of the docs has *two* sections
of caveats in different places, but close together. One called caveats,
one not. That looks like it just led to somebody not reading some
appropriate caveats in the second group of caveats (on -admin).

414c7a537e Change the default setting for log_min_error_statement to ERROR. Per
recent discussion in which majority opinion was that this is a more
widely useful setting than the previous default of PANIC.

e82d9e6283 Adjust elog.c so that elog(FATAL) exits (including cases where ERROR is
promoted to FATAL) end in exit(1) not exit(0).  Then change the postmaster to
allow exit(1) without a system-wide panic, but not for the startup subprocess
or the bgwriter.  There were a couple of places that were using exit(1) to
deliberately force a system-wide panic; adjust these to be exit(2) instead.
This fixes the problem noted back in July that if the startup process exits
with elog(ERROR), the postmaster would think everything is hunky-dory and
proceed to start up.  Alternative solutions such as trying to run the entire
startup process as a critical section seem less clean, primarily because of
the fact that a fair amount of startup code is shared by all postmaster
children in the EXEC_BACKEND case.  We'd need an ugly special case somewhere
near the head of main.c to make it work if it's the child process's
responsibility to determine what happens; and what's the point when the
postmaster already treats different children differently?

aaef29b377 More MSVC build fixes:
* New versions of OpenSSL come with proper debug versions, and use
suffixed names on the LIBs for that. Adapts library handling to deal
with that.

* Fixes error where it incorrectly enabled Kerberos based on NLS
configuration instead of Kerberos configuration

* Specifies path of perl in config, instead of using current one.
Required when using a 64-bit perl normally, but want to build pl/perl
against 32-bit one (required)

* Fix so pgevent generates win32ver.rc automatically

Fix string's length calculation for recoding, fix strlower() to avoid wrong
assumption about length of recoded string (was: recoded string is no greater
that source, it may not true for multibyte encodings)

1a5c450f30 When truncating a relation in-place (eg during VACUUM), do not try to unlink
any no-longer-needed segments; just truncate them to zero bytes and leave
the files in place for possible future re-use.  This avoids problems when
the segments are re-used due to relation growth shortly after truncation.
Before, the bgwriter, and possibly other backends, could still be holding
open file references to the old segment files, and would write dirty blocks
into those files where they'd disappear from the view of other processes.

Back-patch as far as 8.0.  I believe the 7.x branches are not vulnerable,
because they had no bgwriter, and "blind" writes by other backends would
always be done via freshly-opened file references.

d68efb3f8d Repair problems with hash indexes that span multiple segments: the hash code's
preference for filling pages out-of-order tends to confuse the sanity checks
in md.c, as per report from Balazs Nagy in bug #2737.  The fix is to ensure
that the smgr-level code always has the same idea of the logical EOF as the
hash index code does, by using ReadBuffer(P_NEW) where we are adding a single
page to the end of the index, and using smgrextend() to reserve a large batch
of pages when creating a new splitpoint.  The patch is a bit ugly because it
avoids making any changes in md.c, which seems the most prudent approach for a
backpatchable beta-period fix.  After 8.3 development opens, I'll take a look
at a cleaner but more invasive patch, in particular getting rid of the now
unnecessary hack to allow reading beyond EOF in mdread().

Backpatch as far as 7.4.  The bug likely exists in 7.3 as well, but because
of the magnitude of the 7.3-to-7.4 changes in hash, the later-version patch
doesn't even begin to apply.  Given the other known bugs in the 7.3-era hash
code, it does not seem worth trying to develop a separate patch for 7.3.

4f335a3d7f Repair two related errors in heap_lock_tuple: it was failing to recognize
cases where we already hold the desired lock "indirectly", either via
membership in a MultiXact or because the lock was originally taken by a
different subtransaction of the current transaction.  These cases must be
accounted for to avoid needless deadlocks and/or inappropriate replacement of
an exclusive lock with a shared lock.  Per report from Clarence Gardner and
subsequent investigation.

that discusses CVS. Remove the recommendation to use cvs 1.10. Remove

build cvsup from source because the existing text is outdated, and
more accurate information is available from the CVSup homepage.
