In particular, copy_remote_files() would report any kind of non-zero
exit status from rsync as an error, even though when cloning data
directories and tablespaces we explicitly ignore the "vanished
files" status (code 24) as it's expected behaviour for files in these
locations to disappear during the rsync copy process.
Previously providing a parameter which requires a value (e.g. -f/--config-file)
would result in a misleading error like "Unknown option -f".
Rather than suppress getopt's error messages, we'll rely on these to inform
about missing required values or unknown options (as other PostgreSQL tools
do), though we will still provide our own list of command line errors and
warnings countered above and beyond getopt's sanity checks.
These are now prefixed with "service_" to emphasize that they're
OS-level commands, not repmgr ones; also added reload and promote
commands:
service_start_command
service_stop_command
service_restart_command
service_reload_command
service_promote_command
GitHub #169
Causes repmgr to wait for the updated node record to propagate
to the standby before exiting. This can be used to ensure that
actions which depend on the standby's node record being synchronised
(such as starting repmgrd) are not carried out prematurely.
Addresses GitHub #103
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.
- 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
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
Optionally prompt for superuser and repmgr user when creating a witness.
This ensures a password can be provided if the primary's pg_hba.conf
mandates it.
This deprecates '--initdb-no-pwprompt'; and changes the default behaviour of
"repmgr create witness", which previously required a superuser password
unless '--initdb-no-pwprompt' was supplied.
This behaviour is more consistent with other PostgreSQL utilities such
as createuser.
Partial fix for GitHub issue #145.
