Thread: plperl features
Patch provide support for array type and pseudo type
(anyelement, anyarray) for function parameters and result.
for example:
CREATE FUNCTION add_three_values(anyelement, anyelement, anyelement)
RETURNS anyelement AS '
return $_[0]+$_[1]+$_[2];
' LANGUAGE plperl;
CREATE FUNCTION make_array(anyelement, anyelement, anyelement) RETURNS
anyarray AS '
return [$_[0], $_[1], $_[2]];
' LANGUAGE plperl;

Indeed. This patch breaks those defenses...

No, because you diked out the check at lines 1452ff, rather than
upgrading it to something correct.
I find the "fn_retispseudo" and "arg_is_p" flags pretty bogus anyway
since they fail to indicate *which* pseudotype it is. You might as
well just test for the specific type OID.

New patch. I have added the check pseudo-type argumetns.
Specific type is substituted in runtime, during function call.

I assume this is an 8.0 fix.
Your patch has been added to the PostgreSQL unapplied patches list at:
http://momjian.postgresql.org/cgi-bin/pgpatches
It will be applied as soon as one of the PostgreSQL committers reviews
and approves it.

On the other hand, it wouldn't be that nice for the community that respects a good freeze. As you know, there will always be one more feature.

I can't apply this patch because the code has changed too much. Would
you regenerate a patch against current CVS?
Also, this indenting seems wrong:

Putting an 'if' after an 'if' is just too strange. Please make a more
complete fix that has proper block indenting.
Also, I don't think the arg_is_p variable is really the proper fix for
this, but I am unsure what to recomment. Others?

The thing I didn't like about that was that it assumes there is only
one pseudotype behavior that is or ever will be interesting for plperl.
I think it'd probably make more sense to store an array of the parameter
type OIDs and then check for ANYELEMENT or ANYARRAY as such in the
places where the patch uses arg_is_p.

This was the patch that I took the array processing piece from and attempted to fix, since it was badly broken. However, I'm not happy about any of the ways of doing it, and suspect I won't get it done for 8.1. I think we need that piece done before we look at ANYELEMENT/ANYARRAY. cheers andrew Bruce Momjian wrote: >Sergej, are you going to repost this patch? > >--------------------------------------------------------------------------- > >Tom Lane wrote: > > >>Bruce Momjian <pgman@candle.pha.pa.us> writes: >> >> >>>Also, I don't think the arg_is_p variable is really the proper fix for >>>this, but I am unsure what to recomment.

Added to TODO:

o Add support for polymorphic arguments and return types to plperl

I am not working on this right now (or anything else for 8.1) - the original plperl array to pg array implementation was broken and I was not happy about the fix I first came up with, and ran out of time to work on an acceptable solution. Neither is Abhijit, to the best of my knowledge - he has today submitted a patch for SPI fetching via cursor, which should not affect this stuff. We recently put the two items on the TODO list, as I understood from Joshua that you guys weren't working on plperl at all in the 8.1 feature freeze time frame. cheers andrew
