-====

-This file contains a list of improvements which are desireable and/or have
-been requested, and which we aim to address/implement when time and resources
-permit.
-
-It is *not* a roadmap and there's no guarantee of any item being implemented
-within any given timeframe.

-Enable suspension of repmgrd failover
-------------------------------------
-
-When performing maintenance, e.g. a switchover, it's necessary to stop all
-repmgrd nodes to prevent unintended failover; this is obviously inconvenient.
-We'll need to implement some way of notifying each repmgrd to suspend automatic
-failover until further notice.
-
-Requested in GitHub #410 ( https://github.com/2ndQuadrant/repmgr/issues/410 )

-      For testing new features and bug fixes, from time to time 2ndQuadrant provides
-      so-called &quot;snapshot packages&quot; via its public repository. These packages
-      are built from the &repmgr; source at a particular point in time, and are not formal
-      releases.
-    </para>
-    <note>
-      <para>
-        We do not recommend installing these packages in a production environment
-        unless specifically advised.
-      </para>
-    </note>
-    <para>
-      To install a snapshot package, it's necessary to install the 2ndQuadrant public snapshot repository,
-      following the instructions here: <ulink url="https://dl.2ndquadrant.com/default/release/site/">https://dl.2ndquadrant.com/default/release/site/</ulink> but replace <literal>release</literal> with <literal>snapshot</literal>
-      in the appropriate URL.
-    </para>
-    <para>
-      For example, to install the snapshot RPM repository for PostgreSQL 9.6, execute (as <literal>root</literal>):
-      <programlisting>
-curl https://dl.2ndquadrant.com/default/snapshot/get/9.6/rpm | bash</programlisting>
-
-      or as a normal user with root sudo access:
-      <programlisting>
-curl https://dl.2ndquadrant.com/default/snapshot/get/9.6/rpm | sudo bash</programlisting>
-    </para>
-    <para>
-      Alternatively you can browse the repository here:

-    </para>
-    <para>
-      Once the repository is installed, installing or updating &repmgr; will result in the latest snapshot
-      package being installed.
-    </para>
-    <para>
-      The package name will be formatted like this:
-      <programlisting>
-repmgr96-4.1.1-0.0git320.g5113ab0.1.el7.x86_64.rpm</programlisting>

-      of the <application>git</application> commit it was built from (here: <literal>g5113ab0</literal>).
-    </para>
-
-    <para>
-      Note that the next formal release (in the above example <literal>4.1.1</literal>), once available,
-      will install in place of any snapshot builds.

-    To do this, specify the appropriate command for each action
-    in <filename>repmgr.conf</filename> using the following configuration
-    parameters:
-    <programlisting>
-    service_start_command
-    service_stop_command

-      It's also possible to specify a <varname>service_promote_command</varname>.
-      This is intended for systems which provide a package-level promote command,
-      such as Debian's <application>pg_ctlcluster</application>, to promote the
-      PostgreSQL from standby to primary.
-    </para>
-    <para>
-      If your packaging system does not provide such a command, it can be left empty,
-      and &repmgr; will generate the appropriate `pg_ctl ... promote` command.
-    </para>
-    <para>
-      Do not confuse this with <varname>promote_command</varname>, which is used

-    To confirm which command &repmgr; will execute for each action, use
-    <command>repmgr node service --list --action=...</command>, e.g.:
-    <programlisting>
-      repmgr -f /etc/repmgr.conf node service --list --action=stop
-      repmgr -f /etc/repmgr.conf node service --list --action=start
-      repmgr -f /etc/repmgr.conf node service --list --action=restart
-      repmgr -f /etc/repmgr.conf node service --list --action=reload</programlisting>
-  </para>
-
-  <para>
-     These commands will be executed by the system user which &repmgr; runs as (usually <literal>postgres</literal>)
-     and will probably require passwordless sudo access to be able to execute the command.
-  </para>
-  <para>
-    For example, using <application>systemd</application> on CentOS 7, the service commands can be

-      service_restart_command = 'sudo systemctl restart postgresql-9.6'
-      service_reload_command  = 'sudo systemctl reload postgresql-9.6'</programlisting>
-    and <filename>/etc/sudoers</filename> should be set as follows:
-    <programlisting>
-      Defaults:postgres !requiretty
-      postgres ALL = NOPASSWD: /usr/bin/systemctl stop postgresql-9.6, \
-        /usr/bin/systemctl start postgresql-9.6, \

Ian Barwick	f6a6df3600	repmgrd: renable monitoring data recording when in archive recovery. The warning emitted gives the impression that monitoring data shouldn't be written if there's no streaming replication, but we can and should do this as long as we have a primary connection. Explictly document this in the code. Also remove an unused variable warning.	2017-11-20 15:29:21 +09:00

Ian Barwick	e331069f53	Escape double-quotes in strings passed to an event notification script The string in question will be generated internally by repmgr as a simple one-line string with no control characters etc., so all that needs to be escaped at the moment are any double quotes.	2017-11-16 10:38:55 +09:00

Ian Barwick	a3428e4d8a	repmgrd: simplify the candidate selection logic All disconnected nodes will be in a static, known state, so as long as each node has the same meta-information (repmgr.nodes) and is able to retrieve the last receive LSN of the other nodes, it is possible for each node to independently determine the best promotion candidate, thereby reaching consensus without an explicit "voting" process.	2017-11-09 19:51:13 +09:00
Ian Barwick	03b9475755	repmgrd: fixes to failover handling get_new_primary() returns NULL if no notification for the new primary has been received, but the code was expecting it to return UNKNOWN_NODE_ID, which was causing repmgrd to prematurely drop out of the new primary detection loop if no notification had been received by the time the loop started. Also store the electoral term as a single row, single column table, to ensure that all repmgrds see the same turn. It is then bumped by the winning node after it gets promoted. Various logging improvements.	2017-11-09 19:51:09 +09:00
