9.5 introduces the tablespace_map file, which is created on the upstream
node while a backup is running. We need to overwrite this with the
provided values.
Note that we only write explicitly-provided values to the tablespace_map
file, however the existing symlinks for non-specified tablespaces
will have been copied anyway.
Fixes Github #119.
Registering a master creates the schema, but it may be desirable
to forcibly reregister a master without deleting the schema, so
uncouple the dependency.
Also ensure schema creation is atomic by wrapping it in a transaction.
Per GitHub issue #49.
In some cases it is desirable to remove repmgr's handling of a standby, perhaps
because that standby is to be removed altogether. With no UNREGISTER command,
one had to manually delete the corresponding row from repl_nodes.
repmgrd correctly updates ID of the upstream node after automatic
failover, but repmgr was not doing that for manual failvers.
This moves the existing function to dbutils and modifies it so that
it does not rely on global variables with configuration (available
just in repmgrd).
This should fix issue #67 (hopefully, haven't done much testing).
If no configuration file provided, also check default Postgres
sysconfig dir.
It would also be useful to check the configuration directory
provided by the RPM/DEB packages, not sure if that's programmatically
feasible.
Currently repmgr/repmgrd will only accept these as valid when
provided as the first command line option, however it's possible
a user will want to get the output of those options by adding
them to the end of a previously inputted command.
Note that after the first of these options is encountered, the
program will terminate and not process any other options. This
is consistent with psql's behaviour
Per GitHub issue #107 from Sébastien Gross.
If freopen() fails, stderr is diverted to an undisclosed location
and it's not clear what is going on.
Also add an explicit notice announcing our intention to divert
logging output to a file.
Per #105.
Note that it might make sense to disable logfile output when
running the repmgr command line client as normally you'd expect
immediate feedback.
repmgr does not require explicit provision of the target data
directory when cloning a standby (it defaults to the same directory
as on the master). However this is a required option for pg_basebackup
which was only being provided if repmgr's -D/--data-dir option was
set, so ensure we always provide whatever repmgr is using.
Per report from Martín.
The main change is that now check_connection requires a conninfo
parameter, and the connection object has type (PGconn **) so it can be
replaced by check_connection if needed.
The bug was caused by the fact that the first failure resulted in
*conn == NULL, so that subsequent checks of the upstream connection
were failing irrespectively of the actual state of the upstream node.
Now, when *conn == NULL, check_connection will use conninfo to
establish a new connection and place it into *conn. We introduce a new
INTERNAL_ERROR code for the case when they are both NULL.
In passing, we also reworded a confusing error message, distinguishing
a timeout from the actual elapsed time.
Ignore blank lines which consist of whitespace. Per issue #71 in
GitHub.
This fix also improves comment handling and will treat lines with
whitespace before the '#' character as whitespace.
