timing, I know :)) At the moment the digest() function returns
hexadecimal coded hash, but I want it to return pure binary. I
have also included functions encode() and decode() which support
'base64' and 'hex' encodings, so if anyone needs digest() in hex
he can do encode(digest(...), 'hex').
Main reason for it is "to do one thing and do it well" :)
Another reason is if someone needs really lot of digesting, in
the end he wants to store the binary not the hexadecimal result.
It is really silly to convert it to hex then back to binary
again. As I said if someone needs hex he can get it.
Well, and the real reason that I am doing encrypt()/decrypt()
functions and _they_ return binary. For testing I like to see
it in hex occasionally, but it is really wrong to let them
return hex. Only now it caught my eye that hex-coding in
digest() is wrong. When doing digest() I thought about 'common
case' but hacking with psql is probably _not_ the common case :)

- These methods in org.postgresql.jdbc2.ResultSet are now implemented:
getBigDecimal(int) ie: without a scale (why did this get missed?)
getBlob(int)
getCharacterStream(int)
getConcurrency()
getDate(int,Calendar)
getFetchDirection()
getFetchSize()
getTime(int,Calendar)
getTimestamp(int,Calendar)
getType()
NB: Where int represents the column name, the associated version
taking a String were already implemented by calling the int
version.
- These methods no longer throw the not implemented but the new noupdate
error. This is in preparation for the Updateable ResultSet support
which will overide these methods by extending the existing class to
implement that functionality, but needed to show something other than
notimplemented:
cancelRowUpdates()
deleteRow()
- Added new error message into errors.properties "postgresql.noupdate"
This is used by jdbc2.ResultSet when an update method is called and
the ResultSet is not updateable. A new method notUpdateable() has been
added to that class to throw this exception, keeping the binary size
down.
- Added new error message into errors.properties "postgresql.psqlnotimp"
This is used instead of unimplemented when it's a feature in the
backend that is preventing this method from being implemented.
- Removed getKeysetSize() as its not part of the ResultSet API

- Applied modified patch from Richard Bullington-McGuire
<rbulling@microstate.com>. I had to modify it as some of the code
patched now exists in different classes, and some of it actually
patched obsolete code.
Wed Jan 17 10:19:00 GMT 2001 peter@retep.org.uk
- Updated Implementation to include both ANT & JBuilder
- Updated README to reflect the changes since 7.0
- Created jdbc.jpr file which allows JBuilder to be used to edit the
source. JBuilder _CAN_NOT_ be used to compile. You must use ANT for
that. It's only to allow JBuilders syntax checking to improve the
drivers source. Refer to Implementation for more details

Eliminate some of the more blatant platform-dependencies ... it
builds here now, anyway ...
----------------------------
Which basically changes u_int*_t -> uint*_t, so now it does not
compile neither under Debian 2.2 nor under NetBSD 1.5 which
is platform independent<B8> all right. Also it replaces $KAME$
with $Id$ which is Bad Thing. PostgreSQL Id should be added as a
separate line so the file history could be seen.
So here is patch:
* changes uint*_t -> uint*. I guess that was the original
intention
* adds uint64 type to include/c.h because its needed
[somebody should check if I did it right]
* adds back KAME Id, because KAME is the master repository
* removes stupid c++ comments in pgcrypto.c
* removes <sys/types.h> from the code, its not needed

1. Distinguish cases where a Datum representing a tuple datatype is an OID
from cases where it is a pointer to TupleTableSlot, and make sure we use
the right typlen in each case.
2. Make fetchatt() and related code support 8-byte by-value datatypes on
machines where Datum is 8 bytes. Centralize knowledge of the available
by-value datatype sizes in two macros in tupmacs.h, so that this will be
easier if we ever have to do it again.
level" locks. A session lock is not released at transaction commit (but it
is released on transaction abort, to ensure recovery after an elog(ERROR)).
In VACUUM, use a session lock to protect the master table while vacuuming a
TOAST table, so that the TOAST table can be done in an independent
transaction.
I also took this opportunity to do some cleanup and renaming in the lock
code. The previously noted bug in ProcLockWakeup, that it couldn't wake up
any waiters beyond the first non-wakeable waiter, is now fixed. Also found
a previously unknown bug of the same kind (failure to scan all members of
a lock queue in some cases) in DeadLockCheck. This might have led to failure
to detect a deadlock condition, resulting in indefinite waits, but it's
difficult to characterize the conditions required to trigger a failure.
$(CC) $(CFLAGS) $(LDFLAGS) <object files> <extra-libraries> $(LIBS) -o $@
This form seemed to be the most portable, readable, and logical, but in any
case it's better than having a dozen different ones in the tree.
in pghackers list. Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention. pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'. A newstyle function must be identified
by an associated info routine. See src/backend/utils/fmgr/README.
maintained for each cache entry. A cache entry will not be freed until
the matching ReleaseSysCache call has been executed. This eliminates
worries about cache entries getting dropped while still in use. See
my posting to pg-hackers of even date for more info.
kibitzing from Tom Lane. Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'. This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines. LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.
INITDB forced!
source directory. This involves mostly makefiles using $(srcdir) when they
might have used ".". (Regression tests don't work with this, yet.)
Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS). Add "override" keyword
in most places, to preserve necessary flags even when the user overrode the
flags.
Remove a bunch of crufty code for large-object-based arrays, which is
superseded by TOAST and likely hasn't worked in a long time anyway.
Clean up array code a little, and in particular eliminate its habit
of scribbling on the input array (ie, modifying the input tuple :-().
* the result is not recorded anywhere
* the result is not used anywhere
* the result is only used in some places, whereas others have been getting away with it
* the result is used improperly
Also make command line options handling a little better (e.g., --disable-locale,
while redundant, should really still *dis*able).
* Add option to build with OpenSSL out of the box. Fix thusly exposed
bit rot. Although it compiles now, getting this to do something
useful is left as an exercise.
* Fix Kerberos options to defer checking for required libraries until
all the other libraries are checked for.
* Change default odbcinst.ini and krb5.srvtab path to PREFIX/etc.
* Install work around for Autoconf's install-sh relative path anomaly.
Get rid of old INSTL_*_OPTS variables, now that we don't need them
anymore.
* Use `gunzip -c' instead of g?zcat. Reportedly broke on AIX.
* Look for only one of readline.h or readline/readline.h, not both.
* Make check for PS_STRINGS cacheable. Don't test for the header files
separately.
* Disable fcntl(F_SETLK) test on Linux.
* Substitute the standard GCC warnings set into CFLAGS in configure,
don't add it on in Makefile.global.
* Sweep through contrib tree to teach makefiles standard semantics.
... and in completely unrelated news:
* Make postmaster.opts arbitrary options-aware. I still think we need to
save the environment as well.
Does not work since it fetches one byte beyond the source data, and when
the phase of the moon is wrong, the source data is smack up against the
end of backend memory and you get SIGSEGV. Don't laugh, this is a fix
for an actual user bug report.

Note, Bruce I found in the contrib tree any files that we forget
remove during contrib cleaning. Please remove these files:

prepared for dirtribution (it needs a little changes). I can change and work
on this, but I need motivation :-)
And Peter, I know and I agree that standard PG tree is not good space for
all interfaces and for all tools based on PG, but LO is PG feature and we
haven't backup tool for LO.

quote-stripping, and acl-checking tasks for these functions from the
parser, and do them at function execution time instead. This fixes
the failure of pg_dump to produce correct output for nextval(Foo)
used in a rule, and also eliminates the restriction that the argument
of these functions must be a parse-time constant.
here is an updated version of the bit type with a bugfix and all the necessa
ry
SQL functions defined. This should replace what is currently in contrib. I'd
appreciate any comments on what is there.
Kind regards,

Makefiles now), there's no reason for os2client to maintain its own
copy of c.h just to change #define PORTNAME. Simplify Makefile
accordingly. Get rid of horribly-out-of-date modified copy of c.h,
which should never have been in the distribution to start with,
since it's actually a derived file. Now it's not needed anyway.
this is an old patch which I have already submitted and never seen
in the sources. It corrects the datatype oids used in some iterator
functions. This bug has been reported to me by many other people.
contrib-datetime.patch
some code contributed by Reiner Dassing <dassing@wettzell.ifag.de>
contrib-makefiles.patch
fixes all my contrib makefiles which don't work with some compilers,
as reported to me by another user.
contrib-miscutil.patch
an old patch for one of my old contribs.
contrib-string.patch
a small change to the c-like text output functions. Now the '{'
is escaped only at the beginning of the string to distinguish it
from arrays, and the '}' is no more escaped.
elog-lineno.patch
adds the current lineno of CopyFrom to elog messages. This is very
useful when you load a 1 million tuples table from an external file
and there is a bad value somehere. Currently you get an error message
but you can't know where is the bad data. The patch uses a variable
which was declared static in copy.c. The variable is now exported
and initialized to 0. It is always cleared at the end of the copy
or at the first elog message or when the copy is canceled.
I know this is very ugly but I can't find any better way of knowing
where the copy fails and I have this problem quite often.
plperl-makefile.patch
fixes a typo in a makefile, but the error must be elsewhere because
it is a file generated automatically. Please have a look.
tprintf-timestamp.patch
restores the original 2-digit year format, assuming that the two
century digits don't carry much information and that '000202' is
easier to read than 20000202. Being only a log file it shouldn't
break anything.
Please apply the patches before the next scheduled code freeze.
I also noticed that some of the contribs don't compile correcly. Should we
ask people to fix their code or rename their makefiles so that they are
ignored by the top makefile?

family functions. Contain:
conversion from a datetype to formatted text:
to_char( datetime, text)
to_char( timestamp, text)
to_char( int4, text)
to_char( int8, text)
to_char( float4, text)
to_char( float8, text)
to_char( numeric, text)
vice versa:
to_date ( text, text)
to_datetime ( text, text)
to_timestamp ( text, text)
to_number ( text, text) (convert to numeric)
PostgreSQL to_char is very compatible with Oracle's to_char(), but not
total exactly (now). Small differentions are in number formating. It will
fix in next to_char() version.
! If will this patch aplly to the main tree, must be delete the current
to_char version in contrib (directory "dateformat" and note in contrib's
README), this patch not erase it (sorry Bruce).

additional argument specifying the kind of lock to acquire/release (or
'NoLock' to do no lock processing). Ensure that all relations are locked
with some appropriate lock level before being examined --- this ensures
that relevant shared-inval messages have been processed and should prevent
problems caused by concurrent VACUUM. Fix several bugs having to do with
mismatched increment/decrement of relation ref count and mismatched
heap_open/close (which amounts to the same thing). A bogus ref count on
a relation doesn't matter much *unless* a SI Inval message happens to
arrive at the wrong time, which is probably why we got away with this
sloppiness for so long. Repair missing grab of AccessExclusiveLock in
DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi.
Recommend 'make clean all' after pulling this update; I modified the
Relation struct layout slightly.
Will post further discussion to pghackers list shortly.
I have updated my contrib code for version 6.5. In the attachment you will
find the directories array, datetime, miscutil, string, tools and userlocks
which replace the corresponding directories under contrib.
In contrib/tools you will find some developement scripts which I use while
hacking the sources. I hope they will be useful for some other people.
I have also added a contrib/Makefile which tries to compile and install all
the contribs. Unfortunately many of them don't have a Makefile or don't
compile cleanly.

Clark
I've changed the check_primary_key() function code to allow for either
the "automatic insert key rule" or "dependent insert key rule".
Previously it restricted the addtion of a child entry if the
corresponding parent entry was not there. Now if the option is
"automatic" it will add an entry in the parent too ( it will be
successful if there are no no-null fields in the parent apart from the
primary key).
The way to use it now is:
:/*
* check_primary_key () -- check that key in tuple being
inserted/updated
* references existing tuple in "primary" table.
* Though it's called without args You have to specify referenced
* table/keys while creating trigger: key field names in triggered
table,
* referenced table name, referenced key field names,type of action
[automatic|dependent]:
* EXECUTE PROCEDURE
* check_primary_key ('Fkey1', 'Fkey2', 'Ptable', 'Pkey1', 'Pkey2',
'[automatic|dependent]').

Here is a tar file the new directories, which substitute the old ones
in contrib. Please remove the old directories array, datetime, miscutil,
string and userlock before unpacking the tar file in contrib.
Note that as the modules are now installed in lib/modules I install all
my sql code in lib/sql. In my opinion also the other contributors should
follow these rules.
test isn't that complete up to now, but I think it shows
enough of the capabilities of the module.
The Makefile assumes it is located in a directory under
pgsql/src/pl. Since it includes Makefile.global and
Makefile.port and doesn't use any own compiler/linker calls,
it should build on most of our supported platforms (I only
tested under Linux up to now). It requires flex and bison I
think. Maybe we should ship prepared gram.c etc. like for the
main parser too?

Here is some more contrib-fodder, based on TIH's IP address type,

track of the things in my library).
inclusion in pgsql. I have included a README which should be enough
to start using it, plus a BENCH file that describes some timings
I have done.
Please have a look at it, and if you think everything is OK, I
would like it seen included in the contrib-section of pgsql.
I don't think I will do any more work in this, but maybe it inspires
somebody else to improve on it.

our internal IP routing data base, and because I have participated
in Ingres development here in Russia in RUBIN/DEMOS project -
through it was not freeware work - and it was very interesting for
me too see such good freeware data base as PostgreSQL), and I
modified 'ipaddr' data type library in accordance to our requests
and to allow SQL do indexing over ipaddr objects.
You can read description at 'http://relcom.EU.net/ipaddr.html' and
get sources at 'http://relcom.EU.net/ip_class.tar.gz'. It contains
sources, sql scripts for incorporating new data type into postgres
(including ipaddr_ops operator class incorporation) and 20,000
records based data test for the indexing.
I am not sure if it's proper mail list for this information, and
if it's interesting for anyone except me to get full-functional
ipaddress class. I am ready to make all modifications, bug fixing
and documentation for this data class if it's nessesary for it's
contribution to the Postgres data base.
Anyway, all my work was based at original 'ip&mac data type'
contribution, written by Tom Ivar Helbekkmo.
Be free to write me any questions or requests about this work.

I do not know about these contributions well as I only made the binaries
to contribute to a Japanese Linux package.(I did not test them.) But I
try to make some brief introduction about the contrib directory with my
poor English. Here is a draft of README about contrib directory:
This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).
implementation that's in contrib/ip_and_mac/. This one works right
with 6.3, avoids the problems I ran into earlier with LIKE, and
includes a bit of extra functionality.
From: Tom I Helbekkmo <tih@Hamartun.Priv.NO>
PostgreSQL type extensions for IP and MAC addresses.
I needed to record IP and MAC level ethernet addresses in a data
base, and I really didn't want to store them as plain strings, with
no enforced error checking, so I put together the accompanying code
as my first experiment with adding a data type to PostgreSQL. I
then thought that this might be useful to others, both directly and
as a very simple example of how to do this sort of thing, so here
it is, in the hope that it will be useful.
