crm configure show to a pipe

Post #1 of 6 (2291 views)

Hi Kristoffer, all,

running 'crm configure show > file' appends non-printable chars at the
end (at least if op_defaults is used):

...
property cib-bootstrap-options: \
dc-version=1.1.12-c191bf3 \
cluster-infrastructure=corosync \
cluster-recheck-interval=10m \
stonith-enabled=false \
no-quorum-policy=freeze \
last-lrm-refresh=1415955398 \
maintenance-mode=false \
stop-all-resources=false \
stop-orphan-resources=true \
have-watchdog=false
rsc_defaults rsc_options: \
allow-migrate=false \
failure-timeout=10m \
migration-threshold=INFINITY \
multiple-active=stop_start \
priority=0
op_defaults op-options: \
record-pending=true.[?1034h

Best,
Vladislav

Hi,

Best to use crm configure save for filtering (I guess that you
don't want colors in that case). As for strange codes output,
they're most likely due to some libreadline bug and TERM set to
xterm. I found some information at the time here:

https://bugs.gentoo.org/show_bug.cgi?id=246091

We dealt with that then by not importing readline unless
absolutely necessary. The changeset is 4d11007. My bad for not
commenting that in the code.

readline probably gets imported in non-interactive mode again.

Thanks,

Dejan

Great! How I missed that? :)
The only noticeable difference that it is impossible to save partial
CIB, filtering by object ids (like 'show' allows).

I can confirm that yes, it does. My apologies for reintroducing this
issue! I will change this.

I will also look at adding optional filtering to the save command just
like for show and edit. This seems like a useful feature to me.

Thank you for you extremely productive work!

No need to apologize, it's really convoluted and I failed to
add a comment about it.

I guess that the idea of save was to be able to backup/restore.
But the set of filters is readily available anyway, so it may
just as well be extended.

Cheers,
