Runtime Directories & UNIX Sockets
|
|
----------------------------------
|
|
|
|
The zrepl daemon needs to open various UNIX sockets in a runtime directory:
|
|
|
|
* a ``control`` socket that the CLI commands use to interact with the daemon
|
|
* the :ref:`transport-ssh+stdinserver` listener opens one socket per configured client, named after ``client_identity`` parameter
|
|
|
|
There is no authentication on these sockets except the UNIX permissions.
|
|
The zrepl daemon will refuse to bind any of the above sockets in a directory that is world-accessible.
|
|
|
|
The following sections of the ``global`` config shows the default paths.
|
|
The shell script below shows how the default runtime directory can be created.
|
|
|
|
::
|
|
|
|
global:
|
|
control:
|
|
sockpath: /var/run/zrepl/control
|
|
serve:
|
|
stdinserver:
|
|
sockdir: /var/run/zrepl/stdinserver
|
|
|
|
|
|
::
|
|
|
|
mkdir -p /var/run/zrepl/stdinserver
|
|
chmod -R 0700 /var/run/zrepl
|
|
|
|
|
|
Durations & Intervals
|
|
---------------------
|
|
|
|
Interval & duration fields in job definitions, pruning configurations, etc. must match the following regex:
|
|
|
|
::
|
|
|
|
var durationStringRegex *regexp.Regexp = regexp.MustCompile(`^\s*(\d+)\s*(s|m|h|d|w)\s*$`)
|
|
// s = second, m = minute, h = hour, d = day, w = week (7 days)
|
|
|
|
Super-Verbose Job Debugging
|
|
---------------------------
|
|
|
|
You have probably landed here because you opened an issue on GitHub and some developer told you to do this...
|
|
So just read the annotated comments ;)
|
|
|
|
::
|
|
|
|
job:
|
|
- name: ...
|
|
...
|
|
# JOB DEBUGGING OPTIONS
|
|
# should be equal for all job types, but each job implements the debugging itself
|
|
debug:
|
|
conn: # debug the io.ReadWriteCloser connection
|
|
read_dump: /tmp/connlog_read # dump results of Read() invocations to this file
|
|
write_dump: /tmp/connlog_write # dump results of Write() invocations to this file
|
|
rpc: # debug the RPC protocol implementation
|
|
log: true # log output from rpc layer to the job log
|
|
|
|
.. ATTENTION::
|
|
|
|
Connection dumps will almost certainly contain your or other's private data. Do not share it in a bug report.
