- added pgpool-II-3.6.1_implicit.patch

Fri Feb 10 13:00:00 2017 mrueckertAATTsuse.de
- update to 3.6.1
- Improve the behavior of fail-over. In the steaming replication
mode, client sessions will not be disconnected when a fail-over
occurs any more if the session does not use the failed standby
server. If the primary server goes down, still all sessions
will be disconnected. Also it is possible to connect to
Pgpool-II even if it is doing health checking retries. Before
all attempt of connecting to Pgpool-II failed while doing
health checking retries.
- New PGPOOL SET command has been introduced. Certain
configuration parameters now can be changed on the fly in a
session.
- Watchdog is significantly enhanced. It becomes more reliable
than previous releases.
- Handling of extended query protocol (e.g. used by Java
applications) in streaming replication mode speeds up if many
rows are returned in a result set.
- Import parser of PostgreSQL 9.6.
- In some cases pg_terminate_backend() now does not trigger a
fail-over.
- Change documentation format from raw HTML to SGML.
For all the details see /usr/share/doc/packages/pgpool-II/NEWS

Mon Oct 3 14:00:00 2016 mrueckertAATTsuse.de
- update to 3.5.4
- Fix buffer over run problem in \"show pool_nodes\". (Tatsuo
Ishii) While processing \"show pool_nodes\", the buffer for
hostname was too short. It should be same size as the buffer
used for pgpool.conf. Problem reported by a twitter user who
is using pgpool on AWS (which could have very long hostname).
- Fix usage of wait(2) in pgpool main process. (Tatsuo Ishii) The
usage of wait(2) in pgpool main could cause infinite wait in
the system call. Solution is, to use waitpid(2) instead of
wait(2).
- Save and restore errno in each signal handler. (Tatsuo Ishii)
- Fix handling of pcp_listen_addresses config parameter.
(Muhammad Usama)
- Fix \"kind mismatch\" error message in pgpool. (Muhammad Usama)
Many of \"kind mismatch...\" errors are caused by notice/warning
messages produced by one or more of the DB nodes. In this case
now Pgpool-II forwards the messages to frontend, rather than
throwing the \"kind mismatch...\" error. This would reduce the
chance of \"kind mismatch...\" errors. See [pgpool-hackers:
1501] for more details.
- Replace \"MAJOR\" macro to prevent occasional failure. (Tatsuo
Ishii) The macro calls pool_virtual_master_db_node_id() and
then access backend->slots[id]->con using the node id returned.
In rare cases, it could point to 0 (in case when the DB node is
not connected), which gives access to con->major, then it
causes a segfault. See bug 225 for related info.
- Fixing a coding mistake in watchdog code. (Muhammad Usama)
wd_issue_failover_lock_command() function is supposed to
forward command type passed in as an argument to the
wd_send_failover_sync_command() function instead it was passing
the NODE_FAILBACK_CMD command type. The commit also contains
some log message enhancements.
- doc : Fixing a typo in english doc (Muhammad Usama)
- Fix for bun 215 that pgpool doesn\'t escalate ip in case of
another node inavailability. (Muhammad Usama) The heartbeat
receiver fails to identify the heartbeat sender watchdog node
when the heartbeat destination is specified in terms of an IP
address while wd_hostname is configured as a hostname string or
vice versa. See bug 215 for related info.
- Fix for bug of inconsistent status of Postgresql nodes in
Pgpool instances after restart.(Muhammad Usama) Watchdog does
not synchronize status. See bug 218 for related info.
- SIGUSR1 signal handler should be installed before watchdog
initialization. (Muhammad Usama) Since there can be a case
where a failover request from other watchdog nodes arrive at
the same time when the watchdog has just been initialized, and
if we wait any longer to install a SIGUSR1 signal handler, it
can result in a potential crash.
- Fix for bug 228 that pgpool doesn\'t de-escalate IP in case
network restored. (Muhammad Usama) See bug 228 for related
info.
- Fix hang when portal suspend received. (Tatsuo Ishii) See bug
230 for related info.
- test : Add regression test for bug 230. (Tatsuo Ishii)
- Fixing a typo in the log message. (Muhammad Usama)
- Fixing the error messages when the socket operation fails.
(Muhammad Usama)
- Tighten up health check timer expired condition in
pool_check_fd(). (Muhammad Usama)
- doc : Add comment to the document about connection_cache.
(Tatsuo Ishii)
- Fix Handling of pcp_socket_dir was missing from
pool_get_config(). (Muhammad Usama)
- doc : Fix Japanese document typo. (Bo Peng)
- Fix \"out of memory\" by using \"pg_md5 -m\".(Muhammad Usama) See
bug 236 for related info.
- Fix for 237 that Pgpool-II fails to start if listen_addresses
is empty string. (Muhammad Usama) The socket descriptor array
(fds[]) was not getting the array end marker when TCP listen
addresses are not used. See bug 237 for related info.

Thu Jul 7 14:00:00 2016 mrueckertAATTsuse.de
- update to 3.5.3
- New features
- Allow to access to pgpool while doing health checking (Tatsuo
Ishii)
Currently any attempt to connect to pgpool fails if pgpool is
doing health check against failed node even if
fail_over_on_backend_error is off because pgpool child first
tries to connect to all backend including the failed one and
exits if it fails to connect to a backend (of course it
fails). This is a temporary situation and will be resolved
before pgpool executes failover. However if the health check
is retrying, the temporary situation keeps longer depending
on the setting of health_check_max_retries and
health_check_retry_delay. This is not good. Attached patch
tries to mitigate the problem:
- When an attempt to connect to backend fails, give up
connecting to the failed node and skip to other node,
rather than exiting the process if operating in streaming
replication mode and the node is not primary node.
- Mark the local status of the failed node to \"down\".
- This will let the primary node be selected as a load
balance node and every queries will be sent to the primary
node. If there\'s other healthy standby nodes, one of them
will be chosen as the load balance node.
- After the session is over, the child process will suicide
to not retain the local status.
Per [pgpool-hackers: 1531].
- Bug fixes
- Fix is_set_transaction_serializable() when SET
default_transaction_isolation TO \'serializable\'. (Bo Peng)
SET default_transaction_isolation TO \'serializable\' is sent
to not only primary but also to standby server in streaming
replication mode, and this causes an error. Fix is, in
streaming replication mode, SET default_transaction_isolation
TO \'serializable\' is sent only to the primary server.
See bug 191 for related info.
- Fix Chinese documetation bug about raw mode (Yugo Nagata, Bo
Peng) Connection pool is avalilable in raw mode.
- Fix confusing comments in pgpool.conf (Tatsuo Ishii)
- Fix extended protocol handling in raw mode (Tatsuo Ishii)
Bug152 reveals that extended protocol handling in raw mode
(actually other than in stream mode) was wrong in Describe()
and Close(). Unlike stream mode, they should wait for
backend response.
See bug 152 for related info.
- Permit pgpool to support multiple SSL cipher protocols
(Muhammad Usama)
Currently TLSv1_method() is used to initialize the SSL
context, that puts an unnecessary limitation to allow only
TLSv1 protocol for SSL communication. While postgreSQL
supports other ciphers protocols as well. The commit changes
the above and initializes the SSLSession using the
SSLv23_method() (same is also used by PostgreSQL). Because it
can negotiate the use of the highest mutually supported
protocol version and remove the limitation of one specific
protocol version.
- If statement timeout is enabled on backend and do_query()
sends a (Tatsuo Ishii) query to primary node, and all of
following user queries are sent to standby, it is possible
that the next command, for example END, could cause a
statement timeout error on the primary, and a kind mismatch
error on pgpool-II is raised.
This fix tries to mitigate the problem by sending sync
message instead of flush message in do_query(), expecting
that the sync message reset the statement timeout timer if we
are in an explicit transaction. We cannot use this technique
for implicit transaction case, because the sync message
removes the unnamed portal if there\'s any.
Plus, pg_stat_statement will no longer show the query issued
by do_query() as \"running\".
See bug 194 for related info.
- Deal with the case when the primary is not node 0 in
streaming replication mode. (Tatsuo Ishii)
http://www.pgpool.net/mantisbt/view.php?id=194#c837 reported
that if primary is not node 0, then statement timeout could
occur even after bug194-3.3.diff was applied. After some
investigation, it appeared that MASTER macro could return
other than primary or load balance node, which was not
supposed to happen, thus do_query() sends queries to wrong
node (this is not clear from the report but I confirmed it in
my investigation).
pool_virtual_master_db_node_id(), which is called in MASTER
macro returns query_context->virtual_master_node_id if query
context exists. This could return wrong node if the variable
has not been set yet. To fix this, the function is modified:
if the variable is not either load balance node or primary
node, the primary node id is returned.
- Fix a posible hang during health checking (Yugo Nagata)
Helath checking was hang when any data wasn\'t sent from
backend after connect(2) succeeded. To fix this,
pool_check_fd() returns 1 when select(2) exits with EINTR due
to SIGALRM while health checkking is performed.
Reported and patch provided by harukat and some modification
by Yugo.
See bug 204 for related info.
- change the Makefile under this directory src/sql/,that is
proposed by (Bo Peng) [pgpool-hackers: 1611]
- fix for 0000197: pgpool hangs connections to database..
(Muhammad Usama)
The client connection was getting stuck when backend node and
remote pgpool-II node becomes unavailable at the same time.
The reason was a missing command timeout handling in the
function that sends the IPC commands to watchdog.
- Fix bug with load balance node id info on shmem
(Tatsuo Ishii)
There are few places where the load balance node was
mistakenly put on wrong place. It should be placed on:
ConnectionInfo
*con_info[child id, connection pool_id,
backend id].load_balancing_node]. In fact it was placed on:

* con_info[child id, connection pool_id, 0].load_balancing_node].
As long as the backend id in question is 0, it is ok. However
while testing pgpool-II 3.6\'s enhancement regarding failover,
if primary node is 1 (which is the load balance node) and
standby is 0, a client connecting to node 1 is disconnected
when failover happens on node 0. This is unexpected and the
bug was revealed.
It seems the bug was there since long time ago but it had not
found until today by the reason above.
- Fixing coverity scan reported issues. (Muhammad Usama)

Mon May 9 14:00:00 2016 mrueckertAATTsuse.de
- update to 3.5.2
- Bug fixes
- Fix for segfault during trusted_servers check (Muhammad
Usama) PostgreSQL\'s memory and exception manager APIs adopted
by the pgpool 3.4 are not thread safe and are causing the
segmentation fault in the watchdog lifecheck process, as it
uses the threads to ping configured trusted hosts for
checking the upstream connections. Fix is to remove threads
and use the child process approach instead. See
[pgpool-general: 4569] for more details.
- Removing the limit on the maximum number of items in the
black_function_list and white_function_list lists (Muhammad
Usama) extract_string_tokens in pool_config uses the fixed
size malloc on the array to hold the
black_function_list/white_function_list items. This imposes
a limit of maximum items in these lists. The fix is to use
realloc to increase the array size when it gets full.
- Fix check \"PCP Directory\" in \"Parameter Setting\" in install
(Nozomi Anzai) The command \"pcp_system_info\" was discarded in
3.5, but pgpoolAdmin still confirmed if it existed.
Per bug #187.
- Fix extended protocol hang with empty query (Tatsuo Ishii)
The fixes related to extended protocol cases in 3.5.1 broke
the case of empty query. In this case backend replies with
\"empty query response\" which is same meaning as a command
complete message. Problem is, when empty query response is
received, pgpool does not reset the query in progress flag
thus keeps on waiting for backend. However, backend will not
send the ready for query message until it receives a sync
message. Fix is, resetting the in progress flag after
receiving the empty query response and reads from frontend
expecting it sends a sync message. Per bug #190.
- Redirect all user queries to primary server (Tatsuo Ishii) Up
to now some user queries are sent to other than the primary
server even if load_balance_mode = off. This commit changes
the behavior: if load_balance_mode = off in streaming
replication mode, now all the user queries are sent to the
primary server only. Per bug #189.
- Change the PID length of pcp_proc_count command result to 6
characters long (Bo Peng) If the pgpool process ID are over 5
characters, the 6th character of each process ID will be
removed. This commit changes the process ID length of
pcp_proc_count command result to 6 characters long.
Per bug #188.

Mon Apr 25 14:00:00 2016 mrueckertAATTsuse.de
- update to 3.5.1
- Bug fixes
- Add some warning messages for wd_authkey hash calculation
failure (Yugo Nagata) Sometimes wd_authkey calculation fails
for some reason other than authkey mismatch. The additional
messages make these distingushable for each other.
- test: Fix regression test to check timeout of each test (Yugo
Nagata)
- test: Allow timeout value to be specified by the command
option (Yugo Nagata)
- Fix compile issue on FreeBSD (Muhammad Usama) Added missing
include files. Per bug #166. The patch is contributed by the
bug reporter and enhanced a little by Usama.
- test: Fix test/regression/clean.sh to remove binary files of
010.rewrite_timestamp test (Yugo Nagata)
- Fix memorry leak reported by Coverity (CID 1350095) (Yugo
Nagata)
- Fixing pgpool-recovery module compilation issue with
PostgreSQL 9.6 (Muhammad Usama) Incorporating the change of
function signature for GetConfigOption..() functions in
PostgreSQL 9.6.
- Fix to properly process an empty query that has only comments
(Tatsuo Ishii) Pgpool-II recognized an empty query, for
example \"/
* DBD::Pg ping test v3.5.3
*/\" (note that it has no
\';\') as an error and emits message \"Unable to parse the
query\". This is because raw_parser() cannot distinguish an
empty query from an error query due to the poor API design.
To fix this new out parameter \"
*error\" added to the function.
If an error occurred, the variable is set to true and caller
can know the reason why raw_parser() returns NIL is because
of an error query or an empty query. Per bug #154. See
[pgpool-hackers: 1359] for additional information.
- Fix a reset query stuck problem (Muhammad Usama) The solution
is to report FRONTEND_ERROR instead of simple ERROR when
pool_flush on front-end socket fails. The original report is
[pgpool-general: 4265] Pgpool - connection hangs in DISCARD
ALL The patch was generated by Usama and Pawel
Ufnalewski, and Gerhard Wiesinger
helped to verify and test the fix.
- Fix a reset query stuck problem (Tatsuo Ishii) After
receiving X message from frontend, if pgpool-II detects EOF
on the connection before sending reset query, pgpool-II could
wait for a response from backend which had not received the
reset query. To fix this, if EOF received, treat this as
FRONTEND_ERROR, rather than ERROR. See \"[pgpool-hackers:
1440] Yet another reset query stuck problem\" for more
details.
- Fix query stuck problems in streaming replication mode with
extended protocol queries (Tatsuo Ishii) This fix is for both
bug #167 and #168.
- Fix pgpool hung after receiving error state from backend
(Tatsuo Ishii) This could happend if we execute an extended
protocol query and it fails. Per bug #169.
- Fix bug that child processes exit and are not re-spawned
(Muhammad Usama) The problem was due to a logical mistake in
the code for checking the exiting child process type when the
watchdog is enabled. Also the severity of the message emitted
for child exits due to max connection reached from FATAL to
LOG. Per [pgpool-general: 4519] Worker Processes Exit and
Are Not Re-spawned
- Fix typo in configure (Tatsuo Ishii) Patch provided by Thomas
Munro.
- doc: Change description of backend_flag (Tatsuo Ishii) It is
pointed out that restarting pgpool-II is not necessary. Per
[pgpool-general-jp: 1394].
- doc: Fix installation procedure. (Tatsuo Ishii) With
PostgreSQL 9.4 or later, installing pgpool_regclass is not
needed.
- test: Fix pgpool_setup to not confuse log output (Tatsuo
Ishii) Before it simply redirects stdout and stderr of pgpool
processes to a log file. This could cause the log contents
being garbled or even missed because of race condition caused
by multiple process being writing concurrently. To fix this,
pgpool_setup now generates startall script in which pgpool
sends stdout/stderr to cat command by pipe, and cat writes to
the log file.
- Fix to validate the PCP packet length (Muhammad Usama)
Without the validation check, a malformed PCP packet can
crash the PCP child and/or can run the server out of memory
by sending the packet with a very large data size.
- update admin to 3.5.1
- Show the path to .pcppass (Nozomi Anzai)
- Fix not to confirm the status of \"pcp_systemdb_info\" command
if the version is 3.5 [pgpool-general: 4427] (Nozomi Anzai)
- Add chinese templates help (pengbo)
- Change the chinese message catalog (pengbo)
- Fix the argument\'s name (Nozomi Anzai)

http://www.pgpool.net/mantisbt/view.php?id=149

Thu Aug 13 14:00:00 2015 mrueckertAATTsuse.de
- use the pgpool version for the subpackage

Thu Aug 13 14:00:00 2015 mrueckertAATTsuse.de
- split out the extension building in another spec file, so we can
build for multiple postgresql versions.

Thu Aug 13 14:00:00 2015 mrueckertAATTsuse.de
- update to version 3.4.3
- Fix \"cannot find xlog functions\" error in pgpool-recovery
(Muhammad Usama) The argument data type of PostgreSQL\'s
pg_xlogfile_name() function has been changed from text to
pg_lsn since PostgreSQL 9.4. And pgpool-recovery was still
trying to locate the function by old signature.
- Fix problem with memory cache invalidation (Muhammad Usama) The
internal buffer for storing the table oids needs to be homed in
long living memory context as it has to survive throughout the
child life. See [pgpool-general: 3643] for details.
- Pass empty string parameters in failover command when pgpool-II
does not have a value for any particular parameter (Muhammad
Usama) Instead of omitting the values for the parameters when
pgpool-II does not have any value for a particular parameter,
it now passes an empty string to the failover command. This
makes sure that failover script will always receive the exact
number of expected parameters.
- pgpool-II should use the local definition of snprintf functions
only if they are not provided by OS (Muhammad Usama)
- Add debug info to show how much shared memory is allocated
(Tatsuo Ishii)
- Downgrading the error level for EOF on backend connection for
main process (Muhammad Usama) Throwing the FATAL error when EOF
is encountered with backend is very harsh in pgpool main
process and can cause undesirable behavior. Downgrading it to
simple ERROR.
- doc: Clarify load balancing condition (Tatsuo Ishii)
- doc: Clarify description of pcp_promote_node (Tatsuo Ishii) It
does not actually promote PostgreSQL standby.
- doc: Fix outdated limitation description about load balancing
using JDBC driver (Tatsuo Ishii) Even if autocommit is false,
load balancing is possible in certain conditions.
- Fix a misplaced code which makes a log code unreachable and
rephrase the log message (Muhammad Usama)
- Fix a problem in elog.c when forwarding a message to frontend
clients (Muhammad Usama) Error while forwarding the message to
the frontend client can potentially cause the infinite
recursion and terminate the child with ERRORDATA_STACK_SIZE
exceeded error. Fix is to check the recursion depth of
send_message_to_frontend() function and pulling the plug if it
is more than two levels deep.
- Fix \"select() system call interrupted\" error (Tatsuo Ishii) The
health check process complains above and then: ERROR: failed
to make persistent db connection DETAIL: connection to
host:\"x.x.x.x:5432 failed However, the healthchek triggers
neither fail over nor retrying. So, except the annoying
messages above, everything goes well. This could occur more
easily if 1) num_init_children is big and 2) pgpool children go
into idle state (no query arrived from client for
child_life_time seconds). Original bug report is
[pgpool-general: 3756] Connection Interrupted. Patch created
by Tatsuo Ishii. Enhancement from Usama.
- Fix the case when user table includes spaces (Tatsuo Ishii) For
example if table names including spaces are used, pgpool-II
cannot be handled correctly by the internal functions which
access system catalogs and it results in SQL errors. Solution
is, to always use delimited identifier. Per bug #136.
http://www.pgpool.net/mantisbt/view.php?id=136 Also see
[pgpool-general: 3818].
- Allow to use in-memory query cache size more than 4GB (Tatsuo
Ishii) This should have been allowed since in memory query
cache was born.
- Do not send a query for checking insert lock in non replication
mode with extended query (Tatsuo Ishii)
- Save pgpool_status to disk each time when it is changed (Tatsuo
Ishii) Previously, pgpool-II saves pgpool_status file when
pgpool-II explicitly is going shutdown. This is fine in most
cases and it saves slight CPU cycles. But if pgpool-II killed
abnormally or the system forces pgpool-II to go down by OOM
killer, next pgpool-II restarting could load obsolete status
file.

Mon May 11 14:00:00 2015 mrueckertAATTsuse.de
- update to 3.4.2
- rpm: Fix %tmpfiles_create to not be executed in RHEL/CentOS 6
(Nozomi Anzai)
- Fix to reset on_exit call back functions in exec_if_cmd and
exec_ping worker processes (Muhammad Usama) exec_if and
exec_ping child processes were inheriting the parent exit
callback functions which could result in undesired behavior if
one of these commands fails. Fixed by adding on_exit_reset() at
child start-up in both processes.
- Fix to use void
* type for receiving return value of thread
function (Yugo Nagata) Previously int type was used and this
could occur stack buffer overflow. This caused an infinity loop
of ping error at bringing up or down VIP.
- Fix to set SIGCHLD to SIG_DFL instead of SIG_IGN in watchdog
processes (Yugo Nagata) When using waitpid, it isn\'t necessary
to set SIGCHLD to SIG_IGN. Rather, it is harmful, and due to
this it was regarded that ping command exited abnormally in
error even when this succeeded.
- Fix to use waitpid instead of wait in exec_ifconifg (Yugo
Nagata)
- Remove an unnecessary include directive (Yugo Nagata)
- Enlarge POOLCONFIG_MAXDESCLEN to 80 (Tatsuo Ishii) This is used
in show pool_status command and limits the length of parameter
description. Unfortunately recovery_timeout description is 64
chars, which is 1 byte longer than former definition of the
macro.
- doc: Update document of condition for load balancig (Yugo
Nagata) Load balancing is possible in an explicit transaction
block even in replication mode since 3.3.0.
- Support SSL certificate chains in the certificate file for
incoming frontend connections (Muhammad Usama)
- Use to_regclass if available in time stamp rewriting in
replication mode (Tatsuo Ishii)
- Fix to not emits a fatal error message when clear text password
auth is used (Muhammad Usama) The problem was introduced in
pgpool-II after inclusion of exception manager. EOF on the
frontend connection during client authentication should not be
treated as an error when the password authentication method is
used. psql disconnects from the server in such case to get the
password from the terminal, reconnects and sends the read
password to server.
- previous session for the same child had exited because of some
ERROR. (Muhammad Usama)
- Fix a hang when an error occurs in a transaction block with
replication mode (Yugo Nagata) When an error occurs at a
backend node in a transaction block with replication mode,
pgpool-II sends an invalid query to other backends to sync
transaction states. However, previously, this was not sent to
master node, and pgpool-II was waiting for master\'s response
forever.
- Fix a problem with pcp_detach_node about graceful node detach
(Muhammad Usama) When graceful node detach is requested
gracefully, pcp_detach_node should check if it is allowed to
process detach_node command on the particular node before
blocking the incoming connections and closing the existing
connections.
- doc: Update table and flowchart of where a query should be sent
to (Yugo Nagata)
- rpm: pgpool.spec is required only in RHEL/CentOS 7 (Nozomi
Anzai)
- Fix a compilation issue about sighandler_t type on BSD variants
(Muhammad Usama)
- changes from 3.4.1
- RPM: Add to support for memcached. (Tatsuo Ishii)
- Fix number of parameters of pgpool_recovery from 3 to 4.
(Tatsuo Ishii) This really should be done before releasing
3.4.0.
- test: Allow pgpool_setup to set configuration file directory by
setting environment variable PGPOOLDIR (Tatsuo Ishii)
- RPM: Rename RPM file (Yugo Nagata) Rename filename to include
the RHEL version number like PostgreSQL\'s official RPM file.
(e.g. pgpool-II-pg93-3.4.0-2pgdg.rhel6.x86_64.rpm)
- Fix node id range check bug in trigger_failover_command().
(Tatsuo Ishii) The node id should be lower than NUM_BACKENDS.
Probably harmless since callers never pass node ids greater or
equal to NUM_BACKENDS.
- Fix occasional stuck that occures when a NOTIFY message is sent
from a backend. (Muhammad Usama) The issue happens in master
slave mode with load balancing when the client is doing
extended query messaging. per bug #116
http://www.pgpool.net/mantisbt/view.php?id=116
- test: Fix failover script of pgpool_setup to use absolute path
to the database cluster (Tatsuo Ishii)
- test: Reorganize port numbers assigned in pgpool_setup (Tatsuo
Ishii) Assign base port (11000 by default) to pgpool, base port
+ 1 to pcp, port + 2 to PostgreSQL node0, port + 3 to
PostgreSQL node1 and so on.
- Fix a bug that pgpool-II 3.4 can\'t cancel query (Muhammad
Usama)
- test: Add regression test for cancelling query (Muhammad Usama)
- Fix to not use non-thread-safe APIs in thread functions
(Muhammad Usama) pgpool-II has borrowed the Memory and
Exception managers from PostgreSQL which never utilizes the
threads so its APIs are not thread safe. Previously, those API
functions which manipulate the global variables in thread
functions, and it caused to undefined behavior or a
segmentation fault. Especially, the main process could die
silently.
- test: Add memory leak regression test (Tatsuo Ishii)
- Fix a memory leak with long-lived connections (Muhammad Usama)
Problem reporeted in [pgpool-general: 3325].
- Change the log level of \"Frontend Terminated\" message to DEBUG1
from LOG (Muhammad Usama)
- Fix ill signal befavior of SIGCHLD in exec_ifconfig() (Tatsuo
Ishii) For some reason SIGCHLD was set to SIG_IGN
*and
* tries
to wait child process which always fails because SIGCHLD is
never delivered. Due to this \"ifconfig up\" fails when
switching to watchdog master. See \"[pgpool-general: 3310] for
more details.
- Allow $_IP_$ having address prefix in if_up_cmd and if_down_cmd
(Muhammad Usama) Previously, it is assumed that \"$_IP_$\"
keyword will always have a white space at the end, and when
\"$_IP_$\" has address prefix (e.g. $_IP_$/24), this prefix was
ignored. Per bug #122.
http://www.pgpool.net/mantisbt/view.php?id=122
- Fix to not send signal to init process (Muhammad Usama) This is
more of a guard against a situation where a crash of the pgpool
main process can make the child processes to send the signal to
system\'s init process. Per bug #119.
http://www.pgpool.net/mantisbt/view.php?id=119
- RPM: Fix \"error: Installed (but unpackaged) file(s) found\"
while creating RPMs for PostgreSQL 9.4 (Tatsuo Ishii)
- Allow \"show pool_nodes\" to print node ids having more than one
digits (Muhammad Usama) Problem reported in [pgpool-general:
3374].
- Prevent \"WARNING: failed to execute regex matching, pattern is
NULL\" message that could happen when application name is not
set in the old clients (Tatsuo Ishii)
- Fix pgpool main process to shutdown in case of child process
start-up failures (Muhammad Usama) Problem rported in
[pgpool-general: 3358].
- Fix a segmentation fault that could happen in child process
error (Muhammad Usama) Problem reported in [pgpool-general:
3377].
- Fix occasional failure in regression test \'004.watchdog\' (Yugo
Nagata) The patch provided by uehara in bug #127.
http://www.pgpool.net/mantisbt/view.php?id=127
- Fix client connection leak (Tatsuo Ishii) Since 3.4.0 pgpool-II
child does not close the connection to client when it ends the
session. This leads to serious \"CLOSE_WAIT\" flood, which makes
pgpool-II unusable since no new connection from clients
accepted. Problem reported by Pablo Sanchez in
[pgpool-general: 3394].
- Restore SIGCHLD handler to its original after executing
if_up/down_cmd (Yugo Nagata) Previously SIGCHLD was set to
SIGIGN always after if_up/down_cmd. This led to a incorrect
error handling of ping or other commands execution, and warning
messages were output to log even when the command exited
successfully.
- RPM: Add pgpool.service for systemd in RHEL/CentOS 7 (Nozomi
Anzai)
- Fix process termination after several reload with
enabled_pool_hba (Muhammad Usama)
- Tighten up checking for app_name_redirect_preference_list and
database_redirect_preference_list (Tatsuo Ishii) Before empty
application name or database name or invalid DB node number
were silently accepted. Now they are strictly checked and let
raise fatal error when starting up. Problem reported in
[pgpool-general-jp: 1337].
- RPM: Change to use systemd if it is available (Nozomi Anzai)
- Fix the behavior of \"client_min_messages\" configuration
parameter (Muhammad Usama) This parameter controls the minimum
message levels to be sent to the frontend. Previously,
regardless of the value of the parameter all the messages with
severity less than NOTICE level were not being forwarded to the
client.
- update pgpooladmin to 3.4.1
- Fix installer to allow to choose 3.4 version (Tatsuo Ishii)
- dropped pgpool-II-3.4.0_build_failed_with_memcached.patch
- replaced pgpool-II-3.4.0_64bit.patch with

- update to 3.1

* Incompatible changes
- Change the lock method of insert_lock. The previous insert_lock uses row
locking against the sequence relation, but the current one uses row locking
against pgpool_catalog.insert_lock table. The reason is that PostgreSQL
core developers decided to disallow row locking against the sequence
relation to avoid an internal error which it leads. So creating insert_lock
table in all databases which are accessed via pgpool-II beforehand is
required. If does not exist insert_lock table, pgpool-II locks the insert
target table. This behavior is same as pgpool-II 2.2 and 2.3 series. If you
want to use insert_lock which is compatible with older releases, you can
specify lock method by configure options: --enable-sequence-lock,
- -enable-table-lock(Kitagawa)
- Deprecate backend_socket_dir. Instead, if backend_hostname starts with \'/\'
it is regarded the as path to Unix domain. If backend_hostname is left
empty, then default Unix domain path(/tmp) is used. This follows the
convention of libpq interface. Patch contributed by Jehan-Guillaume
(ioguix) de Rorthais.
- Now \"pgpool_walrecrunning()\" was not used. pgpool-II used to consider the
node that is promoted a primary node using the function. Now, pgpool-II
waits for completing of the promotion to primary node because it did not
work as we intended. But we still have a problem that pgpool-II waits while
recovery_timeout, when there is no primary node(Kitagawa)
- Add node_id to each PostgreSQL DB node info in the output of show
pool_nodes(Jean-Paul Argudo)
- Change the handling of sequence functions(nextval, setval) so that they
completely obey setting of black/white_function_list. They were always
handled as write functions before(Kitagawa)

* New features
- Add syslog support. Patch contributed by Gilles Darold. Review and editing
by Guillaume Lelarge.
- Adapt application_name introduced in PostgreSQL 9.0. When reusing
connection, send application_name in the startup packet to backend and send
parameter status to frontend(Tatsuo)
- Add relcache_expire directive to control the expiration of the internal
system catalog cache. ALTER TABLE might make these cache values obsoleted
and the new directive will make the risk lower(Tatsuo).
- Add follow_master_command directive. This directive specifies a command to
run in master/slave streaming replication only after a master failover.
Patch contributed by Gilles Darold.
- Add pcp_promote_node command. This command promotes a new master node to
pgpool-II. This can use in master/slave streaming replication only. Patch
contributed by Gilles Darold.
- Add pcp_pool_status command which produces similar output of show
pool_status. Also C API for this command is added. Patch contributed by
Jehan-Guillaume (ioguix) de Rorthais.
- Add new per backend directive \"backend_flag\". This controls per backend
behavior. Currently \"ALLOW_TO_FAILOVER\" or \"DISALLOW_TO_FAILOVER\" are
allowed(Tatsuo)
- Add health_check_password directive(Nicolas Thauvin)
- Add sr_check_period, sr_check_user and sr_check_password directives. These
are used for streaming replication delay checking and determining primary
node(Tatsuo)
- Add --username(or -u) option to pg_md5 command. This allows to manage users
which do not have UNIX accounts. Japanese document change by Tatsuo
Ishii(Nicolas Thauvin)
- Add pgpool_adm functions to pgpool_adm/. These are user-defined functions
written in C language which work like pcp commands (Jehan-Guillaume
(ioguix) de Rorthais)
- Add Simplified Chinese version of documents(Huang Jian, Sun Peng)
- Add SQL files to uninstall functions to sql/(Nicolas Thauvin)
- In master/slave mode, SELECTs to unlogged table execute only on
master/primary(Kitagawa)

* Bug fixes
- Fix bug which cannot use the cursors of JDBC driver on standby node. The
transaction commands come to be sent to all nodes by this fix in
master/slave mode(Kitagawa)
- Fix bug with the handling of empty queries. The empty queries come to be
handled the same as SELECT queries. This fix allows load-balance after the
empty query(Kitagawa)
- Fix insert_lock so that it works correctly even if the column definition
such as \"DEFAULT nextval((\'\"x_seq\"\'::text)::regclass)\" (Kitagawa)
- Fix pcp_attach_node command so that it emits error message while doing
failover(Kitagawa)
- Fix log message which is emitted when pgpool-II cannot parse the query in
the extended query protocol so that it shows the query (Kitagawa)
- Fix description about backend_weight inpgpool-II manual. It can be changed
by reloading pgpool.conf(Tatsuo)
- Fix and enhance wording in English tutorial document. Fix suggested by
Huang Jian(Tatsuo)
- Fix bug which does not update the node status when reattaching the node in
raw mode(Guillaume Lelarge)
- Fix incorrect calculation of the replication delay in streaming replication
mode(Tatsuo)
- Replace wrong function name \"notice_backend_error\" with correct one
\"degenerate_backend_set\" in the failover log message(Tatsuo)
- Remove unnecessary logging at the end of pgpool.conf parsing(Tatsuo)
- Fix possible crash of pgpool/worker child after attaching new backend. Fix
suggested by Gurjeet Singh(Tatsuo)
- Fix bug that SELECTs which have subquery with FOR SHARE/UPDATE clause are
sent to slave/standby(Tatsuo)
- Fix bug which rewriting timestamp of default value fails in PREPARE
statements. This used to work but was broken in 3.0(Kitagawa)
- Fix fail to compile pcp commands on the environment without
getopt_long()(Tatsuo)
- Fix crash of pgpool child when frontend connects if in raw mode, enable_hba
is off and more than 2 backends(Kitagawa)
- Fix some memory leaks(Kitagawa)

* Enhancements
- Enhance online recovery in streaming replication mode. Now restarting
pgpool-II children is avoided when recovery finished. So existing sessions
can be continued while doing online recovery(Tatsuo)
- pcp_attach_node does not diconnect existing sessions in streaming
replication mode. In other mode, pcp_attache_node still disconnects
existing sessions(Tatsuo).
- Import PostgreSQL 9.0 parser. This allows to use CREATE INDEX with implicit
index name, which is new in 9.0. Patch contributed by Akio Ishida.
- Allow to use regular expressions in black and white function list. Patch
contributed by Gilles Darold. Patch reviewed by Guillaume Lelarge.
- Reorganize pgpool.conf sample files so that they are easier to read
(Guillaume Lelarge)
- Add tags into all parameters in the pgpool-II user
manual(Haruka Takatsuka)
- Enhance online recovery documents in streaming replication(Tatsuo)
- Change the function to check the replication delay in streaming replication
mode. Currently, pgpool uses pg_last_xlog_replay_location() instead of
pg_last_xlog_receive_location(). Fix suggested by Anton Yuzhaninov (Tatsuo)
- Allow time stamp rewriting to work with arbitrary expression in default
value of a column. Before we detected anything including now() then simply
replaced it to now(). This will lead to wrong rewriting of default value.
for example, timezone(\'utc\'::text, now()). Note that, however, this only
adopts to simple queries. Extended protocols(for example Java, PHP PDO)
or SQL \"PREPARE\" still remain same(Tatsuo)
- Enhance the error message which is emitted when failed to check replication
delay(Nicolas Thauvin)
- Change error message \"do_md5: read_password_packet failed\" into debug
level(Kitagawa)
- Allow to compile pgpool-regclass() against PostgreSQL 9.1(Tatsuo)
- Update and sync pgpool-II manuals of English version and Japanese
version(Tatsuo)
- rewritten patches for 3.1:
old name: pgpool2-debian-config.patch
new name: pgpool-II_conf.patch

Fri Mar 18 13:00:00 2011 mrueckertAATTsuse.de
- simplify building of the pgsql extensions.

- move binaries to _sbindir
- added init script and sysconfig file
- create empty pool_password file

Thu Mar 17 13:00:00 2011 mrueckertAATTsuse.de
- create an user + group and tighten up the permissions on the
config to root:pgpool
- build extensions with debug symbols
- dont move the sample config files. just copy them.

Thu Mar 17 13:00:00 2011 mrueckertAATTsuse.de
- build and package the pgsql extensions shipped in pgpool
- split out the shared library
- install config in /etc/pgpool-II

Thu Mar 17 13:00:00 2011 mrueckertAATTsuse.de
- update to version 3.0.3
- Now installing C function \"pgpool-walrecrunning()\" is
recommended if you plan to use streaming replication mode.
This is necessary for better use of online recovery in the
mode. Also new variable \"%P\" can be used in the online
recovery script. If you do not install the function, these
functionalities cannot be used(Tatsuo).
- In raw mode if there\'s only one DB node and if a problem arises
with the DB node, it will be brought to down status. However if
the DB node goes into good condition again, you can use the DB
node without restarting pgpool. This change has been included
in 3.0, but did not work(Tatsuo, Kitagawa)
- Fix non portable code in password authentication. Bug report
from a FreeBSD user(Tatsuo)
- Fix bug that insert_lock locks all rows in user table (Tatsuo,
Kitagawa)
- Fix bug with password authentication. If user name is 32 bytes
long, pgpool child segfaults.(Tatsuo)
- Fix bug with md5 authentication. If raw mode or number of
backend is 1, pgpool child segfaults. Patch contributed by Rob
Shepherd(Tatsuo)
- Fix long standing bug with timestamp rewriting against array
and complex types. Patch contributed by Akio Ishida(Tatsuo)
- Fix bug that debug_level directive doesn\'t work. Patch
contributed by Gilles Darold(Tatsuo)
- Fix possible crash of pgpool child while doing
failover(Kitagawa)
- Fix white/black_function_list so that it works correctly when
user calls function with schema name(Tatsuo)
- Fix bug that DROP DATABASE fails by connection cache(Kitagawa)
- Fix bug that failover fails in raw mode(Kitagawa)
- Fix possible termination of pgpool child when both simple query
protocol and extended query protocol are used in one session
(Kitagawa)
- Fix possible hang up when an error occurs while using extended
query protocol(Kitagawa)
- Fix pgpool-regclass() so that it doesn\'t use PG_TRY/CATCH. It
appeared that using PG_TRY/CATCH is not safe, sometimes backend
dies with PANIC: ERRORDATA_STACK_SIZE exceeded.(Tatsuo)
- Fix bug that select query isn\'t sent to master node when it
meets the following conditions(Kitagawa)
- in MASTER/SLAVE mode
- use extended query protocol
- started transaction explicitly
- after write queries
- Fix bug with load_balance that JDBC driver sends BEGIN to
master node many times(Kitagawa)
- Fix pool_status so that failback_command and
fail_over_on_backend_error show correct values(Kitagawa)
- Remove parameters from pool_status: recovery_password,
system_db_password(Kitagawa)
- Fix online recovery problem in the streaming replication
mode(Tatsuo). Consider following scenario. Suppose node 0 is
the initial primary server and 1 is the initial standby server.
1) Node 0 going down and node 1 promotes to new primary.
2) Recover node 0 as new standby.
3) pgpool-II assumes that node 0 is the new primary.
This problem happens because pgpool-II regarded unconditionally
the youngest node to be the primary. pgpool-II 3.0.3 now checks
each node by using pgpool-walrecrunning() to see if it is a
actually primary or not and is able to avoid the problem and
regards node as standby correctly. Also you can use new variable
\"%P\" to be used in the recovery script. If you do not install
the function, the above problem is not resolved.
- Fix backend complaining \"unexpected EOF on client connection\"
while doing failover in streaming replication mode(Tatsuo)
- Rewrite and review english document(Marc Cousin, Gleu)
- Emit log if particular backend is down status while reading the
status file(Tatsuo)

Thu Nov 18 13:00:00 2010 bitshufflerAATTopensuse.org
- Initial package.
