Teodor Sigaev 08ee64ebf5 Remove usage of ArrayType->flags field, use pgsql's macros BITS_PER_BYTE instead
of self-defined macros, add limit of Array  to gist__int_ops. BTW, intarray now
doesn't support NULLs in arrays.

Teodor Sigaev 0645663e6c New features for tsearch2:
1 Comparison operation for tsquery
2 Btree index on tsquery
3 numnode(tsquery) - returns 'length' of tsquery
4 tsquery @ tsquery, tsquery ~ tsquery - contains, contained for tsquery.
  Note: They don't gurantee exact result, only MAY BE, so it
  useful only for speed up rewrite functions
5 GiST index support for @,~
6 rewrite():
        select rewrite(orig, what, to);
        select rewrite(ARRAY[orig, what, to]) from tsquery_table;
        select rewrite(orig, 'select what, to from tsquery_table;');

Joe Conway 056eb1412c When a cursor is opened using dblink_open, only start a transaction
if there isn't one already open. Upon dblink_close, only commit
the open transaction if it was started by dblink_open, and only
then when all cursors opened by dblink_open are closed. The transaction
accounting is done individually for all named connections, plus
the persistent unnamed connection.

Tom Lane 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.

Tom Lane aa731ed843 Change nextval and other sequence functions to specify their sequence
argument as a 'regclass' value instead of a text string.  The frontend
conversion of text string to pg_class OID is now encapsulated as an
implicitly-invocable coercion from text to regclass.  This provides
backwards compatibility to the old behavior when the sequence argument
is explicitly typed as 'text'.  When the argument is just an unadorned
literal string, it will be taken as 'regclass', which means that the
stored representation will be an OID.  This solves longstanding problems
with renaming sequences that are referenced in default expressions, as
well as new-in-8.1 problems with renaming such sequences' schemas or
moving them to another schema.  All per recent discussion.
Along the way, fix some rather serious problems in dbmirror's support
for mirroring sequence operations (int4 vs int8 confusion for instance).

Bruce Momjian 87688ddf87 The large one adds support for RSA keys and reorganizes
the pubkey functions a bit.  The actual RSA-specific code
there is tiny, most of the patch consists of reorg of the
pubkey code, as lots of it was written as elgamal-only.

---------------------------------------------------------------------------

The SHLIB section was copy-pasted from somewhere and contains
several unnecessary libs.  This cleans it up a bit.

 -lcrypt
   we don't use system crypt()

 -lssl, -lssleay32
   no SSL here

 -lz in win32 section
   already added on previous line

 -ldes
   The chance anybody has it is pretty low.
   And the chance pgcrypto works with it is even lower.

Also trim the win32 section.

---------------------------------------------------------------------------

It is already disabled in Makefile, remove code too.

---------------------------------------------------------------------------

I was bit hasty making the random exponent 'k' a prime.  Further researh
shows that Elgamal encryption has no specific needs in respect to k,
any random number is fine.

It is bit different for signing, there it needs to be 'relatively prime'
to p - 1,  that means GCD(k, p-1) == 1, which is also a lot lighter than
full primality.  As we don't do signing, this can be ignored.

This brings major speedup to Elgamal encryption.

---------------------------------------------------------------------------

o  pgp_mpi_free: Accept NULLs
o  pgp_mpi_cksum: result should be 16bit
o  Remove function name from error messages - to be similar to other
   SQL functions, and it does not match anyway the called function
o  remove couple junk lines

---------------------------------------------------------------------------

o  Support for RSA encryption
o  Big reorg to better separate generic and algorithm-specific code.
o  Regression tests for RSA.

---------------------------------------------------------------------------

o  Tom stuck a CVS id into file.  I doubt the usefulness of it,
   but if it needs to be in the file then rather at the end.
   Also tag it as comment for asciidoc.
o  Mention bytea vs. text difference
o  Couple clarifications

---------------------------------------------------------------------------

There is a choice whether to update it with pgp functions or
remove it.  I decided to remove it, updating is pointless.

I've tried to keep the core of pgcrypto relatively independent
from main PostgreSQL, to make it easy to use externally if needed,
and that is good.  Eg. that made development of PGP functions much
nicer.

But I have no plans to release it as generic library, so keeping such
doc
up-to-date is waste of time.  If anyone is interested in using it in
other products, he can probably bother to read the source too.

Commented source is another thing - I'll try to make another pass
over code to see if there is anything non-obvious that would need
more comments.

Bruce Momjian d51df91897 As Kris Jurka found out, pgcrypto does not work with
OpenSSL 0.9.6x.  The DES functions use the older 'des_'
API, but the newer 3DES functions use the 0.9.7x-only
'DES_' API.

I think I just used /usr/include/openssl/des.h for reference
when implementing them, and had upgraded OpenSSL in the
meantime.

Following patch converts DES also to newer API and provides
compatibility functions for OpenSSL < 0.9.7.

I chose this route because:

- openssl.c uses few DES functions.
- compatibility for old 'des_' API is going away at some point
  of time from OpenSSL.
- as seen from macros, new API is saner
- Thus pgcrypto supports any OpenSSL version from 0.9.5 to 1.0

Tested with OpenSSL 0.9.6c and 0.9.7e.

Bruce Momjian e94dd6ab91 Add missing pgcrypto files from previous commit. 2005-07-10 13:46:29 +00:00
Bruce Momjian 73e2431817 Major pgcrypto changes:
of password-based encryption from RFC2440 (OpenPGP).

The goal of this code is to be more featureful encryption solution
than current encrypt(), which only functionality is running cipher
over data.

Compared to encrypt(), pgp_encrypt() does following:

* It uses the equvialent of random Inital Vector to get cipher
  into random state before it processes user data
* Stores SHA-1 of the data into result so any modification
  will be detected.
* Remembers if data was text or binary - thus it can decrypt
  to/from text data.  This was a major nuisance for encrypt().
* Stores info about used algorithms with result, so user needs
  not remember them - more user friendly!
* Uses String2Key algorithms (similar to crypt()) with random salt
  to generate full-length binary key to be used for encrypting.
* Uses standard format for data - you can feed it to GnuPG, if needed.

Optional features (off by default):

* Can use separate session key - user data will be encrypted
  with totally random key, which will be encrypted with S2K
  generated key and attached to result.
* Data compression with zlib.
* Can convert between CRLF<->LF line-endings - to get fully
  RFC2440-compliant behaviour.  This is off by default as
  pgcrypto does not know the line-endings of user data.

Interface is simple:


    pgp_encrypt(data text, key text) returns bytea
    pgp_decrypt(data text, key text) returns text
    pgp_encrypt_bytea(data bytea, key text) returns bytea
    pgp_decrypt_bytea(data bytea, key text) returns bytea

To change parameters (cipher, compression, mdc):

    pgp_encrypt(data text, key text, parms text) returns bytea
    pgp_decrypt(data text, key text, parms text) returns text
    pgp_encrypt_bytea(data bytea, key text, parms text) returns bytea
    pgp_decrypt_bytea(data bytea, key text, parms text) returns bytea

Parameter names I lifted from gpg:

   pgp_encrypt('message', 'key', 'compress-algo=1,cipher-algo=aes256')

For text data, pgp_encrypt simply encrypts the PostgreSQL internal data.

This maps to RFC2440 data type 't' - 'extenally specified encoding'.
But this may cause problems if data is dumped and reloaded into database
which as different internal encoding.  My next goal is to implement data
type 'u' - which means data is in UTF-8 encoding by converting internal
encoding to UTF-8 and back.  And there wont be any compatibility
problems with current code, I think its ok to submit this without UTF-8
encoding by converting internal encoding to UTF-8 and back.  And there
wont be any compatibility problems with current code, I think its ok to
submit this without UTF-8 support.


Here is v4 of PGP encrypt.  This depends on previously sent
Fortuna-patch, as it uses the px_add_entropy function.

- New function: pgp_key_id() for finding key id's.
- Add SHA1 of user data and key into RNG pools.  We need to get
  randomness from somewhere, and it is in user best interests
  to contribute.
- Regenerate pgp-armor test for SQL_ASCII database.
- Cleanup the key handling so that the pubkey support is less
  hackish.

Marko Kreen
2005-07-10 03:57:55 +00:00
Bruce Momjian 4fcf8b11ff - Add Fortuna PRNG to pgcrypto.
- Move openssl random provider to openssl.c and builtin provider
  to internal.c
- Make px_random_bytes use Fortuna, instead of giving error.
- Retarget random.c to aquiring system randomness, for initial seeding
  of Fortuna.  There is ATM 2 functions for Windows,
  reader from /dev/urandom and the regular time()/getpid() silliness.

Neil Conway 86897f54a8 This patch updates the DDL for contrib/pgcrypto to create all
functions as STRICT, and all functions except gen_salt() as IMMUTABLE.
gen_salt() is VOLATILE.

Although the functions are now STRICT, I left their PG_ARGISNULL()
checks in place as a protective measure for users who install the
new code but use old (non-STRICT) catalog entries (e.g., restored
from a dump).  Per recent discussion in pgsql-hackers.

Tom Lane eb5949d190 Arrange for the postmaster (and standalone backends, initdb, etc) to
chdir into PGDATA and subsequently use relative paths instead of absolute

Bruce Momjian 76eca0ec98 This patch allows contrib/pgcrypto to build with OpenSSL 0.9.8
(currently in beta) when cryptolib = openssl.  According to the
following checkin message from several years ago, OpenSSL application
developers should no longer rely on <openssl/evp.h> to include
everything they need:

http://cvs.openssl.org/chngview?cn=9888

This patch adds the necessary header files.  It doesn't appear to
break anything when building against OpenSSL 0.9.7.

BTW, core appears to build and work fine with OpenSSL 0.9.8.  I've
built 7.3 through HEAD against 0.9.8-beta6 without noticing any
problems.

Teodor Sigaev ef770cbb69 Fixes from Janko Richter <jankorichter@yahoo.de>
- Fix wrong index results on text, char, varchar for multibyte strings
- Fix some SIGFPE signals
- Add support for infinite timestamps
- Because of locale settings, btree_gist can not be a prefix index anymore (for text).
  Each node holds now just the lower and upper boundary.

Tom Lane b5f7cff84f Clean up the rather historically encumbered interface to now() and
current time: provide a GetCurrentTimestamp() function that returns
current time in the form of a TimestampTz, instead of separate time_t
and microseconds fields.  This is what all the callers really want
anyway, and it eliminates low-level dependencies on AbsoluteTime,
which is a deprecated datatype that will have to disappear eventually.

Tom Lane dcf2e1c8c7 Remove the << >> &< and &> operators for contrib/cube, which were

2005-06-27 01:19:43 +00:00
Tom Lane 54c80a3434 Adjust contrib/seg &< and &> operators so that r-tree indexing logic

bogus commutator specifications.

Bruce Momjian bb3cce4ec9 Add E'' syntax so eventually normal strings can treat backslashes
literally.

Add GUC variables:

        "escape_string_warning" - warn about backslashes in non-E strings
        "escape_string_syntax" - supports E'' syntax?
        "standard_compliant_strings" - treats backslashes literally in ''

Update code to use E'' when escapes are used.
2005-06-26 03:04:37 +00:00
Tom Lane b90f8f20f0 Extend r-tree operator classes to handle Y-direction tests equivalent
to the existing X-direction tests.  An rtree class now includes 4 actual
2-D tests, 4 1-D X-direction tests, and 4 1-D Y-direction tests.
This involved adding four new Y-direction test operators for each of
box and polygon; I followed the PostGIS project's lead as to the names
of these operators.
NON BACKWARDS COMPATIBLE CHANGE: the poly_overleft (&<) and poly_overright
(&>) operators now have semantics comparable to box_overleft and box_overright.
This is necessary to make r-tree indexes work correctly on polygons.
Also, I changed circle_left and circle_right to agree with box_left and
box_right --- formerly they allowed the boundaries to touch.  This isn't
actually essential given the lack of any r-tree opclass for circles, but
it seems best to sync all the definitions while we are at it.
2005-06-24 20:53:34 +00:00
Tom Lane 9a09248edd Fix rtree and contrib/rtree_gist search behavior for the 1-D box and
polygon operators (<<, &<, >>, &>).  Per ideas originally put forward
by andrew@supernews and later rediscovered by moi.  This patch just
fixes the existing opclasses, and does not add any new behavior as I
proposed earlier; that can be sorted out later.  In principle this
could be back-patched, since it changes only search behavior and not
system catalog entries nor rtree index contents.  I'm not currently
planning to do that, though, since I think it could use more testing.
2005-06-24 00:18:52 +00:00
Tom Lane 2f5c47e882 Move findoidjoins out of contrib and into src/tools, which is a more
logical place for it since it is of no use to users.  Per recent
discussions on cleaning up contrib.
2005-06-23 02:33:28 +00:00
Tom Lane 5b0c9d3603 Cleanup the contrib/lo module: there is no need anymore to implement
a physically separate type.  Defining 'lo' as a domain over OID works
just fine and is more efficient.  Improve documentation and fix up the
test script.  (Would like to turn test script into a proper regression
test, but right now its output is not constant because of numeric OIDs;
plus it makes Unix-specific assumptions about files it can import.)
2005-06-23 00:06:37 +00:00
Tom Lane d20763dbee Remove contrib modules that have been agreed to be obsolete.
(There are more that will be removed once they've been copied to

2005-06-22 22:56:29 +00:00
Tom Lane 6f7fc0bade Cause initdb to create a third standard database "postgres", which
unlike template0 and template1 does not have any special status in
terms of backend functionality.  However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area.  This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE
DATABASE is unhappy if anyone else is connected to template1.
Patch by Dave Page, minor editing by Tom Lane.  All per recent
pghackers discussions.

Tom Lane 3f749924f8 Simplify uses of readdir() by creating a function ReadDir() that
includes error checking and an appropriate ereport(ERROR) message.
This gets rid of rather tedious and error-prone manipulation of errno,
as well as a Windows-specific bug workaround, at more than a dozen
call sites.  After an idea in a recent patch by Heikki Linnakangas.

Tom Lane 8563ccae2c Simplify shared-memory lock data structures as per recent discussion:
it is sufficient to track whether a backend holds a lock or not, and
store information about transaction vs. session locks only in the
inside-the-backend LocalLockTable.  Since there can now be but one
PROCLOCK per lock per backend, LockCountMyLocks() is no longer needed,
thus eliminating some O(N^2) behavior when a backend holds many locks.
Also simplify the LockAcquire/LockRelease API by passing just a
'sessionLock' boolean instead of a transaction ID.  The previous API
was designed with the idea that per-transaction lock holding would be
important for subtransactions, but now that we have subtransactions we
know that this is unwanted.  While at it, add an 'isTempObject' parameter
to LockAcquire to indicate whether the lock is being taken on a temp
table.  This is not used just yet, but will be needed shortly for
two-phase commit.

Tom Lane 978129f28e Document get_call_result_type() and friends; mark TypeGetTupleDesc()
and RelationNameGetTupleDesc() as deprecated; remove uses of the
latter in the contrib library.  Along the way, clean up crosstab()
code and documentation a little.
2005-05-30 23:09:07 +00:00
Tom Lane 140b078d2a Improve LockAcquire API per my recent proposal. All error conditions
are now reported via elog, eliminating the need to test the result code
at most call sites.  Make it possible for the caller to distinguish a
freshly acquired lock from one already held in the current transaction.
Use that capability to avoid redundant AcceptInvalidationMessages() calls
in LockRelation().
2005-05-29 22:45:02 +00:00
Tom Lane e92a88272e Modify hash_search() API to prevent future occurrences of the error
spotted by Qingqing Zhou.  The HASH_ENTER action now automatically
fails with elog(ERROR) on out-of-memory --- which incidentally lets
us eliminate duplicate error checks in quite a bunch of places.  If
you really need the old return-NULL-on-out-of-memory behavior, you
can ask for HASH_ENTER_NULL.  But there is now an Assert in that path
checking that you aren't hoping to get that behavior in a palloc-based
hash table.
Along the way, remove the old HASH_FIND_SAVE/HASH_REMOVE_SAVED actions,
which were not being used anywhere anymore, and were surely too ugly
and unsafe to want to see revived again.

Tom Lane 191b13aaca Factor out lock cleanup code that is needed in several places in lock.c.
Also, remove the rather useless return value of LockReleaseAll.  Change

Neil Conway c891e05f26 Cleanup GiST header files. Since GiST extensions are often written as
external projects, we should be careful about what parts of the GiST
API are considered implementation details, and which are part of the
public API. Therefore, I've moved internal-only declarations into
gist_private.h -- future backward-incompatible changes to gist.h should
be made with care, to avoid needlessly breaking external GiST extensions.

Also did some related header cleanup: remove some unnecessary #includes
from gist.h, and remove some unused definitions: isAttByVal(), _gistdump(),
and GISTNStrategies.

2005-05-06 17:24:55 +00:00
Tom Lane 177af51c04 Change tsearch2 to not use the unsafe practice of creating functions
that return INTERNAL without also having INTERNAL arguments.  Since the
functions in question aren't meant to be called by hand anyway, I just
redeclared them to take 'internal' instead of 'text'.  Also add code
to ProcedureCreate() to enforce the restriction, as I should have done
to start with :-(

Tom Lane 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.

Teodor Sigaev 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.

Tom Lane 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.

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 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.
