c10dba2fe3 Remove an antiquated comment. 2005-10-13 06:24:05 +00:00
689c815b09 Add a comment describing the requirement that pointers into shared memory
that is protected by a spinlock must be volatile, per recent discussion.

1e9a6ba5e6 Don't try to remove duplicate OR-subclauses in create_bitmap_subplan and
make_restrictinfo_from_bitmapqual.  The likelihood of finding duplicates
seems much less than in the AND-subclause case, and the cost much higher,
because OR lists with hundreds or even thousands of subclauses are not
uncommon.  Per discussion with Ilia Kantor and andrew@supernews.

e952ae1268 Fix longstanding bug found by Atsushi Ogawa: _bt_check_unique would mark
the wrong buffer dirty when trying to kill a dead index entry that's on
a page after the one it started on.  No risk of data corruption, just
inefficiency, but still a bug.

fa72121594 Fix another recently-changed place that was messing with spinlock-
protected data structures and not using a volatile pointer for same.
2005-10-12 16:55:59 +00:00
07eeb9d109 Do all accesses to shared buffer headers through volatile-qualified
pointers, to ensure that compilers won't rearrange accesses to occur
while we're not holding the buffer header spinlock.  It's probably
not necessary to mark volatile in every single place in bufmgr.c,
but better safe than sorry.  Per trouble report from Kevin Grittner.

96a83d8807 Release notes up to date as of today. 2005-10-11 21:17:11 +00:00
a72ee09090 Add infrastructure for making spins_per_delay variable depending on
whether we seem to be running in a uniprocessor or multiprocessor.
The adjustment rules could probably still use further tweaking, but
I'm convinced this should be a win overall.

9907b9775b Don't use a non-locked pre-test of the spinlock on x86_64 machines.
The pre-test has been shown to be a big loss on Opterons and at best a
wash on EM64T.

0cc0d0822d Document that get_attstatsslot/free_attstatsslot only need to be passed
valid type information if they are asked to fetch the values part of a
pg_statistic slot; these arguments are unneeded if fetching only the
numbers part.  Use this to save a catcache lookup in btcostestimate,
which is looking like a bit of a hotspot in recent profiling.  Not a
big savings, but since it's essentially free, might as well do it.

07e6f93d6b Fix oversight in 8.0 modification of RestrictInfo data structures.
A RestrictInfo representing an OR clause now contains two versions of
the contained expression, one with sub-RestrictInfos and one without.
clause_selectivity() should descend to the version with sub-RestrictInfos
so that it has a chance of caching its results for the OR's sub-clauses.
Failing to do so resulted in redundant planner effort.

c6b9924bec Remove the DELETEs from pg_shadow and pg_group that pg_dumpall used to
emit when given the --clean option, in favor of individual DROP ROLE
commands.  The old technique could not possibly work in 8.1, and was
never a very good idea anyway IMHO.  The DROP ROLE approach has the
defect that the DROPs will fail for roles that own objects or have
privileges, but perhaps we can improve that later.
2005-10-10 22:29:48 +00:00
375e7d5579 Use a safer order of operations in dropdb(): rollbackable operations,
ie removing shared-dependency entries, should happen before non-rollbackable
ones.  That way a failure during the rollbackable part doesn't leave us
with inconsistent state.

9178306151 Fix the problem of GRANTs creating "dangling" privileges not directly
traceable to grant options.  As per my earlier proposal, a GRANT made by
a role member has to be recorded as being granted by the role that actually
holds the grant option, and not the member.

d7527540f2 <limits.h> is now needed here, for INT_MAX. Per Michael Fuhr. 2005-10-10 01:34:00 +00:00
313ed1ed94 Fix (hopefully for the last time) problems with datetime values displaying
like '23:59:60' because of fractional-second roundoff problems.  Trying
to control this upstream of the actual display code was hopeless; the right
way is to explicitly round fractional seconds in the display code and then
refigure the results if the fraction rounds up to 1.  Per bug #1927.

18d0ca2d1b Fix Kerberos authentication in wake of virtual-hosts changes --- need
to call krb5_sname_to_principal() always.  Also, use krb_srvname rather
than the hardwired string 'postgres' as the appl_version string in the
krb5_sendauth/recvauth calls, to avoid breaking compatibility with PG
8.0.  Magnus Hagander

426d0158ca Marginal performance improvement in aclmask(): don't bother with
testing ownership if the caller isn't interested in any GOPTION bits
(which is the common case).  It did not matter in 8.0 where the ownership
test was just a trivial equality test, but it matters now.

b888ab82da Recognize ERROR_SHARING_VIOLATION (translate to EACCES), increase log
level for unrecognized win32 error codes to LOG, and make messages
conform to style guide.  Per old suggestion from Qingqing Zhou, which
seems to have gotten lost in the shuffle.

d156e1f850 (Apologies for fat-fingering cvs commit command...) Should have read:
Remove unportable use of tfind/tsearch in favor of bsearch.  Fix up
random number generator to use random() not rand() and to actually honor
its min/max arguments properly.  That wasn't so important before, but
with exposure of capability to ask for general ranges, it will be.
