Hi Tatsuo,


As I promised you I returned back to the project.


As you remember I promised to retest the bug #271 in relation to the hanged requests with streaming replication activated. The good news that the case is not reproduced anymore! Also I reviewed the pgpool bug tracker and I see there are several bug fixes related to the hanged requests. I believe the primary issue was fixed! ))


Best Regards,
Sergey.

At this moment one can observe that memory consumption by a single pgpool process growths unlimited after some period - several minutes (see the attached screenshot). If test is interrupted then the connection is closed and valgrind provided the report listed below. It seems that memory leak is not a memory but just some resources not deallocated until pgpool process exists.

>>>>>>>>>>>>>> Tatsuo,
>>>>>>>>>>>>>>
>>>>>>>>>>>>>>
>>>>>>>>>>>>>> the tests that we started last friday to run for holidays need to be continued because they are huge. I can't share you the preliminary results because I have to be consistent.
>>>>>>>>>>>>>>
>>>>>>>>>>>>>>
>>>>>>>>>>>>>>
>>>>>>>>>>>>>> Meanwhile we observe a lot of the following log messages (see the logs listed below). Our applications not issue requests that should result is such a behavior. Does the pgpool do it? We see that after a connection is committed and closed pgpool initiates one explicit transaction which results in unnatural errors from DB backends.
>>>>>>>>>>>>>
>>>>>>>>>>>>> My guess is Pgpool-II does it when resetting the connection (notice
>>>>>>>>>>>>> "DISCARD ALL" which is issued at the end of a session if it is in the
>>>>>>>>>>>>> "reset_query_list"). By looking at the code, it seems someone added it
>>>>>>>>>>>>> long time ago. However since "DISCARD ALL" implies "DEALLOCATE ALL",
>>>>>>>>>>>>> the code is completely unnecessary and just a waste of cycle. I'm
>>>>>>>>>>>>> going to remove the code.

>>>>>>>>>>>>>>>>> Tatsuo,
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> the test that reproduces 3 problems is attached.
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> Besides switches 231 & 271 it has three new switches described below:
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> 1) Switch 'CONN_HANGS'
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> The test does the sequence of actions:
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - start transaction
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - send PARSE request and execute it several times
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - commit transaction
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - executes request "" (empty string) - this type of requests is used by JBoss Application server to do the connections validation
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - start transaction
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - attempt to send PARSE request <= here is HANGS
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> 2) Switch 'DEALLOCATE'
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> The test simply performs the following set commands:
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - start transaction
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - send parser requests  'select id from write_table limit ?'
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - bind the value '1' and execute statement
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> - commit
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> Pgpool generates the log listed below and it can be seen there is one additional transaction appears!!!

>>>>>>>>>>>>>>>>>>>> Tatsuo,
>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> I'm not sure my understanding of your current patches is correct, but to me it seems that the concept is the following:
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> Probably you'd better to study the extended query section of the
>>>>>>>>>>>>>>>>>>> PostgreSQL's frontend/backend protocol document to understand what
>>>>>>>>>>>>>>>>>>> Pgpool-II tries to do. Anyway,
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> Pgpool saves all prepared statements (SQL statements) mapped to their codes (e.g. S_1 mapped to SELECT name FROM TABLE where ID = ? ). So after any UPDATE request is completely processed and another statement execution request received, and if explicit transaction exists, then pgpool verifies:
>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> 1) if the request is a previously PARSED message then the mapped SQL statement it taken from some memory store and send for parsing to the Master backend. Where the parsing is complete pgpool performs binding and execution of the primary request
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> I'm not sure what "the request" means here. PostgreSQL sends each
>>>>>>>>>>>>>>>>>>> request separately, namely parse/bind/describe/execute/close. I assume
>>>>>>>>>>>>>>>>>>> "the request" means a bind request for now. A bind message can only be
>>>>>>>>>>>>>>>>>>> distinguished by the statement name like "S_1" which was given to the
>>>>>>>>>>>>>>>>>>> previous parse request. There are two types of statements: named
>>>>>>>>>>>>>>>>>>> statement and unnamed statement. "S_1" is a named statement and will
>>>>>>>>>>>>>>>>>>> last until explicitly closed by a close request. So Pgpool-II needs
>>>>>>>>>>>>>>>>>>> to remember the named statement S_1 until explicitly closed (more
>>>>>>>>>>>>>>>>>>> precisely, there are "unnamed statement" and and "unnamed
>>>>>>>>>>>>>>>>>>> portal". Those behave differently from named statements and named
>>>>>>>>>>>>>>>>>>> portal. But I don't want to confuse you and I will not explain them
>>>>>>>>>>>>>>>>>>> for now).  A bind request accepts at least two parameters: a statement
>>>>>>>>>>>>>>>>>>> name and a portal name. A bind request binds the statement and the
>>>>>>>>>>>>>>>>>>> portal along with query parameters if any.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> Execution is another story. It can be done by "execute"
>>>>>>>>>>>>>>>>>>> request. Execute accepts parameter "portal" which is previous created
>>>>>>>>>>>>>>>>>>> by the bind request.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> 2) if the request is not a parsed SQL statement then it is simply forwarded to the master backend
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> What is "the request" exactly? Parse, bind, describe, execute or close?
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> Correct me if I'm wrong but wouldn't it be better not save the described mapping but simply replicate all PARSE requests?
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> No. Remember that Pgpool-II needs to take care of two or more
>>>>>>>>>>>>>>>>>>> PostgreSQL servers. For example, BEGIN or COMMIT must be sent to both
>>>>>>>>>>>>>>>>>>> PostgreSQL servers. A DML/DDL statement must be sent to primary. A
>>>>>>>>>>>>>>>>>>> pure read only SELECT can be sent to either primary or standby.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> So Pgpool-II always need to remember to which PostgreSQL server the
>>>>>>>>>>>>>>>>>>> request message was sent. Otherwise Pgpool-II cannot decicde which
>>>>>>>>>>>>>>>>>>> socket corresponding to PostgreSQL needs to be read while expecting
>>>>>>>>>>>>>>>>>>> responses from PostgreSQL servers. If a PostgreSQL server does not
>>>>>>>>>>>>>>>>>>> send response, Pgpool-II will wait the socket forever, which is
>>>>>>>>>>>>>>>>>>> often seen as a "hang up".
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> Another thing Pgpool-II needs to be careful is, "sync" message. Until
>>>>>>>>>>>>>>>>>>> sync message is sent to backend, PostgreSQL will not return any reply.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> Also Pgpool-II needs to remember the exact sequence of sent messages
>>>>>>>>>>>>>>>>>>> to backend. For example, if pase(BEGIN), bind(BEGIN), execute(BEGIN),
>>>>>>>>>>>>>>>>>>> parse(SELECT), bind(SELECT), execute(SELECT), syncw were sent to
>>>>>>>>>>>>>>>>>>> backend, The reply will be arrive in the order:
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> parse complete(comes from both backend)
>>>>>>>>>>>>>>>>>>> bind complete(comes from both backend)
>>>>>>>>>>>>>>>>>>> command complete(comes from both backend)
>>>>>>>>>>>>>>>>>>> parse complete(comes from only standby)
>>>>>>>>>>>>>>>>>>> bind complete(comes from only standby)
>>>>>>>>>>>>>>>>>>> command complete(comes from only standby)
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> - There is one CONTRA in this proposal - performance. But from my perspective it is not very critical because usually there are not many parsed (prepared from Java perspective) requests of different types in one transaction. It the transaction is long then the logic simply expects some delays, and any way the parse message is already being sent the selected backend.
>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> - The very big PRO here is that the logic of Pgpool will be very Straightforward and you will not be managing extra IFs in the code, one day possibly you will face the 'spaghetti code' problem. This is what you are fighting to now as it seems to me.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> Right.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> We are ready to perform investigation and provide you the performance test results - compare execution times for PARSED messages against NOT PARSED messages. I believe the proposed by me concept was implemented earlier in 3.4.X versions of Pgpool.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> No. 3.4 version or beofore Pgpool sends a sync (more precisely a
>>>>>>>>>>>>>>>>>>> variand of sync, called "flush") message to backend each time
>>>>>>>>>>>>>>>>>>> parse/bind/describe/execute. This produces lots of packet exchange
>>>>>>>>>>>>>>>>>>> between Pgpool and PostgreSQL, which makes the performance was pretty
>>>>>>>>>>>>>>>>>>> bad.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>> To be honest we have several C++ clients for Postgres and after deep investigation we switched off PARSED messages in favor of 'Simple queries'. This is because we were not satisfied with execution plans created by Postgres.
>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>> To be honest, extended query message was not well designed in
>>>>>>>>>>>>>>>>>>> PostgreSQL in the first place. I recommend to use simple query
>>>>>>>>>>>>>>>>>>> protocol.

>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>> Hi Sergey,
>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>> Attached is a patch against master branch as usual.
>>>>>>>>>>>>>>>>>>>>> I also push the changes to the git repository.
>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>> https://git.postgresql.org/gitweb/?p=pgpool2.git;a=shortlog;h=refs/heads/bug271
>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>> When an INSERT is executed in a transaction, a "writing_transaction"
>>>>>>>>>>>>>>>>>>>>> is set. The flag is checked by a succeeding SELECT to decide if
>>>>>>>>>>>>>>>>>>>>> parse_before_bind (which resend the parse message to primary node if
>>>>>>>>>>>>>>>>>>>>> it is executed on the standby) needs to be executed.  The flag is
>>>>>>>>>>>>>>>>>>>>> reset when a command complete message for BEGIN is arrived.  Problem
>>>>>>>>>>>>>>>>>>>>> is, it is possible that the command complete message could arrive
>>>>>>>>>>>>>>>>>>>>> before the bind for the SELECT is executed, and at this point the flag
>>>>>>>>>>>>>>>>>>>>> is already cleared.
>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>> Solution is, do not reset the flag when the command complete message
>>>>>>>>>>>>>>>>>>>>> arrives if in streaming replication mode.
>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>> I tested using your tool and the test case #231 and #271 have been
>>>>>>>>>>>>>>>>>>>>> passed here.

>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>> There is the 'target' folder in the attached tarball (and source codes). The folder contains jar file that implements tests for #231 & #271  issues.
>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>> please run it as:
>>>>>>>>>>>>>>>>>>>>>> # java -jar target/tests-1.0-SNAPSHOT-jar-with-dependencies.jar PGPOOL_HOST PGPOOL_PORT DB_NAME DB_USER DB_PASSWORD 271
>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>> '271' here means the ID of the test to run, currently there are 2 IDs possible - 231 & 271. Each test launched for 1000 times. This is the code level constant so far.

>>>>>>>>>>>>>>>>>>>>>>     Two problems are fixed:
>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>>     - The writing_transaction flag is not reset at transaction
>>>>>>>>>>>>>>>>>>>>>>       committed/aborted. Before it was done in CommandComplete but now it
>>>>>>>>>>>>>>>>>>>>>>       is possible that we need to check the flag before a command complete
>>>>>>>>>>>>>>>>>>>>>>       message arrives. So at Execute, it is taken care by
>>>>>>>>>>>>>>>>>>>>>>       handle_query_context() which used to be a static function in
>>>>>>>>>>>>>>>>>>>>>>       CommandComplete.c. Also the session context memory is always cleared
>>>>>>>>>>>>>>>>>>>>>>       before start a session context.
>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>>     - Ready for query Re-sync code path in read_kind_from_backend did not
>>>>>>>>>>>>>>>>>>>>>>       work. The pending message corresponding to the ready for query
>>>>>>>>>>>>>>>>>>>>>>       message could be a sync message, which does not have query
>>>>>>>>>>>>>>>>>>>>>>       context. But before we checked if there's a query context
>>>>>>>>>>>>>>>>>>>>>>       exists. The check is bogus and removed.
