Hi all,

We have found a strange problem with plv8 functions in PG94RC1

PG 9.3 works fine.

in PG94RC1 in plv8 functions regardless what function does i.e.nothing

CREATE OR REPLACE FUNCTION test.test_text_length_plv8(in_param1 text) RETURNS text
AS
$BODY$
return 'OK'
$BODY$ LANGUAGE plv8;

if length of in_param1 is higher then (or equal to) 200 characters connection just brake... current connection and it brakes - other connections as well... Not sure what it does - but all sessions just says server disconnected and we need and can reconect again....

ie.
SELECT test.test_text_length_plv8('aaaa') works fine

SELECT test.test_text_length_plv8('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa')

exactly 200 chars - just brake conncetion witout any message...but in separate session when we run next command it says:

WARNING:  terminating connection because of crash of another server process
DETAIL:  The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
HINT:  In a moment you should be able to reconnect to the database and repeat your command.

We have tested using pgadmin and psql...

Versions:
PostgreSQL 9.4rc1 on x86_64-unknown-linux-gnu, compiled by gcc (Ubuntu 4.9.1-16ubuntu6) 4.9.1, 64-bit
plv8: 1.5.0-dev1

The same version of plv8 on PG9.3 - works fine without problems...

Any suggestions?

Thanks,

Misa






Update:

all works fine and with: PostgreSQL 9.4beta1 on x86_64-unknown-linux-gnu, compiled by gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2, 64-bit
