3a694bb0a1 Restructure LOCKTAG as per discussions of a couple months ago.
Essentially, we shoehorn in a lockable-object-type field by taking
a byte away from the lockmethodid, which can surely fit in one byte
instead of two.  This allows less artificial definitions of all the
other fields of LOCKTAG; we can get rid of the special pg_xactlock
pseudo-relation, and also support locks on individual tuples and
general database objects (including shared objects).  None of those
possibilities are actually exploited just yet, however.

I removed pg_xactlock from pg_class, but did not force initdb for
that change.  At this point, relkind 's' (SPECIAL) is unused and
could be removed entirely.

0548497cc5 int_aggregate's int_enum() doesn't work correctly with arrays that
aren't 1-D, so give an error message instead of failing.  Per report
from Ron Mayer.

04ce41ca62 Add comment about permissions on pg_ts* tables 2005-04-19 13:58:48 +00:00
Bruce Momjian
7cce39c7ce The following patch should allow UPDATE_INTERVAL to be specified on the
command line. We find this useful because we frequently deal with
thousands of tables in an environment where neither the databases nor
the tables are updated frequently. This helps allow us to cut down on
the overhead of updating the list for every other primary loop of
pg_autovacuum.

I chose -i as the command-line argument and documented it briefly in
the README.

The patch was applied to the 7.4.7 version of pg_autovacuum in contrib.

162bd08b3f Completion of project to use fixed OIDs for all system catalogs and
indexes.  Replace all heap_openr and index_openr calls by heap_open
and index_open.  Remove runtime lookups of catalog OID numbers in
various places.  Remove relcache's support for looking up system
catalogs by name.  Bulky but mostly very boring patch ...

70c9763d48 Convert oidvector and int2vector into variable-length arrays. This
change saves a great deal of space in pg_proc and its primary index,
and it eliminates the former requirement that INDEX_MAX_KEYS and
FUNC_MAX_ARGS have the same value.  INDEX_MAX_KEYS is still embedded
in the on-disk representation (because it affects index tuple header
size), but FUNC_MAX_ARGS is not.  I believe it would now be possible
to increase FUNC_MAX_ARGS at little cost, but haven't experimented yet.
There are still a lot of vestigial references to FUNC_MAX_ARGS, which
I will clean up in a separate pass.  However, getting rid of it
altogether would require changing the FunctionCallInfoData struct,
and I'm not sure I want to buy into that.

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.

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.

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.

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

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.

fa5e44017a Adjust the API for aggregate function calls so that a C-coded function
can tell whether it is being used as an aggregate or not.  This allows
such a function to avoid re-pallocing a pass-by-reference transition
value; normally it would be unsafe for a function to scribble on an input,
but in the aggregate case it's safe to reuse the old transition value.
Make int8inc() do this.  This gets a useful improvement in the speed of
COUNT(*), at least on narrow tables (it seems to be swamped by I/O when
the table rows are wide).  Per a discussion in early December with
Neil Conway.  I also fixed int_aggregate.c to check this, thereby
turning it into something approaching a supportable technique instead
of being a crude hack.

919594f3e2 Some builds (depends on crypto engine support?) of OpenSSL
0.9.7x have EVP_DigestFinal function which which clears all of
EVP_MD_CTX.  This makes pgcrypto crash in functions which
re-use one digest context several times: hmac() and crypt()
with md5 algorithm.

Following patch fixes it by carring the digest info around
EVP_DigestFinal and re-initializing cipher.

So, changed interface to dictionaries, lexize method of dictionary shoud return

have TSLexeme->lexeme == NULL.

typedef struct {

                ( fotball, klubb ) and ( fot, ball, klubb ). So, dictionary
                should return:
