This commit introduces three new options:
- start_command
- stop_command
- restart_command
If these are set, repmgr will issue the specified command instead
of the default pg_ctl commands
- properly distinguish between the command line option -? and getopt's
unknown option marker '?'
- remove deprecated command line options --initdb-no-pwprompt and
-l/--local-port
- add witness command summary in help output
* Version set to 3.2dev
* Binaries are placed in PGBINDIR and then linked from /usr/bin,
instead of being placed into /usr/bin directly. This is necessary
for the switchover command, because it requires pg_rewind, which is
placed in PGBINDIR too.
The LSN reported by the shared memory function defaults to "0/0"
(InvalidXLogRecPtr) - this indicates that the repmgrd on that node
hasn't been able to update it yet. However during failover several
places in the code assumed this is an error, which would cause
an endless loop waiting for updates which would never come.
To get around this without changing function definitions, we can
store an explicit message in the shared memory location field so the
caller can tell whether the other node hasn't yet updated the field,
or encountered situation which means it should not be considered
as a promotion candidate (which in most cases will be because
`failover` is set to `manual`.
Resolves GitHub #222.
This prevents connection error messages being mixed in
with `repmgr cluster show` output. Error message output can
still be enabled with the --verbose flag.
Fixes GitHub #215
This is for consistency with the PostgreSQL source code (see:
src/backend/access/transam/xlog.c ), but as it's not exported
we need to define it ourselves anyway.
From 3.1.4 `repmgr` will behave like other PostgreSQL utilities
when handling database connection parameters, in particular
accepting a conninfo string and honouring libpq connection defaults.
Removed the existing keyword array which has a fixed, limited number
of parameters and replace it with a dynamic array which can be
used to store as many parameters as reported by libpq.
repmgr disallows socket connections anyway (the whole point of providing
the host is to connect to a remote machine) so don't show that as
a fallback default in the -?/--help output.
This matches the behaviour of other PostgreSQL utilities such as pg_basebackup,
psql et al.
Note that unlike psql, but like pg_basebackup, repmgr does not accept a
"left-over" parameter as a conninfo string; this could be added later.
Parameters specified in the conninfo string will override any parameters
supplied correcly (e.g. `-d "host=foo"` will override `-h bar`).
Having successfully connected to the primary, we can use the actual parameters
reported by libpq to create "primary_conninfo", rather than the limited
subset previously defined by repmgr. Assuming that the user can
pass a conninfo string to repmgr (see following commit), this makes it
possible to provide other connection parameters, e.g. related to
SSL usage.
