Add SMF support. Fix default dirs.
2012-11-28 - PgBouncer 1.5.4 - "No Leaks, Potty-Training Successful"
= Fixes =
* DNS: Fix memory leak in getaddrinfo_a() backend.
* DNS: Fix memory leak in udns backend.
* DNS: Fix stats calculation.
* DNS: Improve error message handling for getaddrinfo_a().
* Fix win32 compile.
* Fix compiler dependency support check in configure.
* Few documentation fixes.
2012-09-12 - PgBouncer 1.5.3 - "Quantum Toaster"
= Critical fix =
* Too long database names can lead to crash, which
is remotely triggerable if autodbs are enabled.
The original checks assumed all names come from config files,
thus using fatal() was fine, but when autodbs are enabled
- by '*' in [databases] section - the database name can come
from network thus making remote shutdown possible.
= Minor Features =
* max_packet_size - config parameter to tune maximum packet size
that is allowed through. Default is kept same: (2G-1), but now
it can be made smaller.
* In case of unparseable packet header, show it in hex in log and
error message.
= Fixes =
* AntiMake: it used $(relpath) and $(abspath) to manupulate pathnames,
but the result was build failure when source tree path contained
symlinks. The code is now changed to work on plain strings only.
* console: now SET can be used to set empty string values.
* config.txt: show that all timeouts can be set in floats.
This is well-hidden feature introduced in 1.4.
2012-05-29 - PgBouncer 1.5.2 - "Don't Chew, Just Swallow"
= Fixes =
* Due to mistake, reserve_pool_timeout was taken in microseconds,
not seconds, effectively activating reserve pool immediately
when pool got full. Now use it as seconds, as was intended.
(Noticed by Keyur Govande)
2012-04-17 - PgBouncer 1.5.1 - "Abort, Retry, Ignore?"
= Features =
* Parameters to tune permissions on unix socket:
unix_socket_mode=0777, unix_socket_group=''.
= Fixes =
* Allow empty string for server-side variable - this is
needed to get "application_name" properly working, as it's
the only parameter that does not have server-side default.
* If connect string changes, require refresh of server parameters.
Previously PgBouncer continued with old parameters,
which breaks in case of Postgres upgrade.
* If autodb connect string changes, drop old connections.
* cf_setint: Use strtol() instead atoi() to parse integer config
parameters. It allows hex, octal and better error detection.
* Use sigqueue() to detect union sigval existence - fixes
compilation on HPUX.
* Remove 'git' command from Makefile, it throws random errors
in case of plain-tarball build.
* Document stats_period parameter. This tunes the period for
stats output.
* Require Asciidoc >= 8.4, seems docs are not compatible with
earlier versions anymore.
* Stop trying to retry on EINTR from close().
2012-01-05 - PgBouncer 1.5 - "Bouncing Satisified Clients Since 2007"
If you use more than 8 IPs behind one DNS name, you now need to
use EDNS0 protocol to query. Only getaddrinfo_a()/getaddrinfo()
and UDNS backends support it, libevent 1.x/2.x does not.
To enable it for libc, add 'options edns0' to /etc/resolv.conf.
GNU Make 3.81+ is required for building.
= Features =
* Detect DNS reply changes and invalidate connections to IPs no longer
present in latest reply.
(Petr Jelinek)
* DNS zone serial based hostname invalidation. When option
dns_zone_check_period is set, all DNS zones will be queried
for SOA, and when serial has changed, all hostnames
will be queried. This is needed to get deterministic
connection invalidation, because invalidation on lookup
is useless when no lookups are performed.
Works only with new UDNS backend.
* New SHOW DNS_HOSTS, SHOW DNS_ZONES commands to examine DNS cache.
* New param: min_pool_size - avoids dropping all connections
when there is no load.
(Filip Rembialkowski)
* idle_in_transaction_timeout - kill transaction if idle too long.
Not set by default.
* New libudns backend for DNS lookups. More featureful than evdns.
Use --with-udns to activate. Does not work with IPv6 yet.
* KILL command, to immediately kill all connections for one database.
(Michael Tharp)
* Move to Antimake build system to have better looking Makefiles.
Now GNU Make 3.81+ is required for building.
= Fixes =
* DNS now works with IPv6 hostnames.
* Don't change connection state when NOTIFY arrives from server.
* Various documentation fixes.
(Dan McGee)
* Console: Support ident quoting with "". Originally we did not
have any commands that took database names, so no quoting was needed.
* Console: allow numbers at the stard of word regex. Trying
to use strict parser makes things too complex here.
* Don't expire auto DBs that are paused.
(Michael Tharp)
* Create auto databases as needed when doing PAUSE.
(Michael Tharp)
* Fix wrong log message issued by RESUME command.
(Peter Eisentraut)
* When user= without password= is in database connect string,
password will be taken from userlist.
* Parse '*' properly in takeover code.
* autogen.sh: work with older autoconf/automake.
* Fix run-as-service crash on win32 due to bad basename() from
mingw/msvc runtime. Now compat basename() is always used.
