Tom Lane 87ba04eeaf Add note about risks involved in replaying CREATE TABLESPACE commands
from WAL.  A couple other grammatical improvements too.

Neil Conway f30c76ce8d Adjust CREATE TRIGGER and ALTER TABLE ... ADD FOREIGN KEY to acquire
ExclusiveLock rather than AccessExclusiveLock. This will allow concurrent
SELECT queries to proceed on the table. Per discussion with Andrew at
SuperNews.

Tom Lane cad86e253b WAL must log CREATE and DROP DATABASE operations *without* using any
explicit paths, so that the log can be replayed in a data directory
with a different absolute path than the original had.  To avoid forcing
initdb in the 8.0 branch, continue to accept the old WAL log record
types; they will never again be generated however, and the code can be
dropped after the next forced initdb.  Per report from Oleg Bartunov.
We still need to think about what it really means to WAL-log CREATE
TABLESPACE commands: we more or less have to put the absolute path
into those, but how to replay in a different context??

Tom Lane bd9b4a9d46 Use InitFunctionCallInfoData() macro instead of MemSet in performance
critical places in execQual.  By Atsushi Ogawa; some minor cleanup by moi.

Tom Lane 94e03330cb Create a routine PageIndexMultiDelete() that replaces a loop around
PageIndexTupleDelete() with a single pass of compactification ---
logic mostly lifted from PageRepairFragmentation.  I noticed while
profiling that a VACUUM that's cleaning up a whole lot of deleted
tuples would spend as much as a third of its CPU time in
PageIndexTupleDelete; not too surprising considering the loop method
was roughly O(N^2) in the number of tuples involved.

Tom Lane 775d28302c Fix quote_ident to use quote_identifier rather than its own, not quite
up-to-speed logic; in particular this will cause it to quote names that
match keywords.  Remove unnecessary multibyte cruft from quote_literal
(all backend-internal encodings are 8-bit-safe).

Neil Conway 6a8eb1a7b6 pgcrypto update:
* test error handling
* add tests for des, 3des, cast5
* add some tests to blowfish, rijndael
* Makefile: ability to specify different tests for different crypto
  libraries, so we can skip des, 3des and cast5 for builtin.

Neil Conway 19b676869a pgcrypto update:
Reserve px_get_random_bytes() for strong randomness,
add new function px_get_pseudo_random_bytes() for
weak randomness and use it in gen_salt().

On openssl case, use RAND_pseudo_bytes() for
px_get_pseudo_random_bytes().

Final result is that is user has not configured random
souce but kept the 'silly' one, gen_salt() keeps
working, but pgp_encrypt() will throw error.

Neil Conway 1ea9169b42 pgcrypto update:
* openssl.c: Add 3des and AES support
* README.pgcrypto: list only supported ciphers for openssl

OpenSSL has pre-processor symbol OPENSSL_NO_AES, which
isn't that helpful for detecting if it _does_ exist.
Thus the hack with AES_ENCRYPT.

Neil Conway b160d6b9dc pgcrypto update:
* Use error codes instead of -1
* px_strerror for new error codes
* calling convention change for px_gen_salt - return error code
* use px_strerror in pgcrypto.c

Neil Conway fa332a06ec * construct "struct {} list [] = {}" confuses pgindent - split those.
It was a bad style to begin with, and now several loops can be clearer.
* pgcrypto.c: Fix function comments
* crypt-gensalt.c, crypt-blowfish.c: stop messing with errno
* openssl.c: use px_free instead pfree
* px.h: make redefining px_alloc/px_realloc/px_free easier

Neil Conway 3cc8661232 Remove support for libmhash/libmcrypt.
libmcrypt seems to dead, maintainer address bounces,
and cast-128 fails on 2 of the 3 test vectors from RFC2144.

So I see no reason to keep around stuff I don't trust
anymore.

Support for several crypto libraries is probably only
confusing to users, although it was good for initial
developing - it helped to find hidden assumptions and
forced me to create regression tests for all functionality.

Tom Lane ee4ddac137 Convert index-related tuple handling routines from char 'n'/' ' to bool
convention for isnull flags.  Also, remove the useless InsertIndexResult
return struct from index AM aminsert calls --- there is no reason for
the caller to know where in the index the tuple was inserted, and we
were wasting a palloc cycle per insert to deliver this uninteresting
value (plus nontrivial complexity in some AMs).
I forced initdb because of the change in the signature of the aminsert
routines, even though nothing really looks at those pg_proc entries...

Neil Conway fe7015f5e8 Change the return value of HeapTupleSatisfiesUpdate() to be an enum,

Tom Lane 9e0dd84596 On Windows, use QueryPerformanceCounter instead of gettimeofday for
EXPLAIN ANALYZE instrumentation.  Magnus Hagander
2005-03-20 22:27:52 +00:00
Tom Lane 354049c709 Remove unnecessary calls of FlushRelationBuffers: there is no need
to write out data that we are about to tell the filesystem to drop.
smgr_internal_unlink already had a DropRelFileNodeBuffers call to
get rid of dead buffers without a write after it's no longer possible
to roll back the deleting transaction.  Adding a similar call in
smgrtruncate simplifies callers and makes the overall division of
labor clearer.  This patch removes the former behavior that VACUUM
would write all dirty buffers of a relation unconditionally.

Bruce Momjian 683f60da3d Add mention of why malloc() has to be used in snprintf.c. 2005-03-20 13:54:53 +00:00
Bruce Momjian 8c72526fe9 Department of second thoughts. Remove FRONTEND from snprintf.c because
snprintf is called before the memory system is started.  We have to just
malloc/free.  There are no elogs in the code so we should be fine.
2005-03-20 03:53:39 +00:00
Bruce Momjian 169adfcf74 Fix typo in Makefile. 2005-03-20 02:44:45 +00:00
Bruce Momjian 83ebbfac75 Another change for FRONTEND snprintf.c. 2005-03-20 02:40:28 +00:00
Bruce Momjian 614fcbeba7 Mark snprintf.c as a file that uses FRONTEND and needs to a version in
the server-side port library.  Somehow I missed that change when I added
memory allocation to snprintf.c.

Tom Lane 91728fa26c Add temp_buffers GUC variable to allow users to determine the size
of the local buffer arena for temporary table access.
2005-03-19 23:27:11 +00:00
Tom Lane d65522aeb6 Upgrade localbuf.c to use a hash table instead of linear search to
find already-allocated local buffers.  This is the last obstacle
in the way of setting NLocBuffer to something reasonably large.
2005-03-19 17:39:43 +00:00
Tom Lane 2e629080f7 Put 'dump complete' message in the right place, so it comes out where
it's supposed to when --file option is used.

Tom Lane 88164799ce Need to reset local buffer pin counts, not only shared buffer pins,
before we attempt any file deletions in ShutdownPostgres.  Per Tatsuo.

Michael Meskes 1f418555cf Added patch by Christof Petig <christof@petig-baender.de> to work around gcc bug on powerpc and amd64. 2005-03-18 10:00:43 +00:00
Tom Lane cef01c3355 Avoid infinite loop in InvalidateBuffer if we ourselves are holding
a pin on the victim buffer.
2005-03-18 05:25:23 +00:00
Tom Lane afb66ad8dd Need to release buffer pins before attempting to drop files during
backend exit.  Per report from Bruce.
2005-03-18 05:24:13 +00:00
Tom Lane 7a969cad2e Treat EPERM as a non-error case when checking to see if old postmaster
is still alive.  This improves our odds of not getting fooled by an
unrelated process when checking a stale lock file.  Other checks already
in place, plus one newly added in checkDataDir(), ensure that we cannot
attempt to usurp the place of a postmaster belonging to a different userid,
so there is no need to error out.  Add comments indicating the importance
of these other checks.

Neil Conway d344505d1b This patch moves some code for preprocessing FOR UPDATE from
grouping_planner() to preprocess_targetlist(), according to a comment
in grouping_planner(). I think the refactoring makes sense, and moves
some extraneous details out of grouping_planner().
