Have you considered using the unzipped war file as a masterfiles source and
skipping the intermediate copy and unzip?
That may be my next step but I feel like the approach above should be doable.
There is also the issue of atomicity -- if a new zip file is available then the
existing directory should be removed before any unzipping takes place. I'm not
sure how to do this with cf3 using just a recursive copy. 'rsync' offers
capabilities to delete files on the client that don't exist on the remote host
but I haven't seen such in cf3.
Is this line in error?
Yes, sorry, that was a mistake I made in obfuscating the code. The existing
promise is correct:
"/somewhere/$(zipfiles).war"
create => "true",
copy_from =>
remote_dcp("$(def.source_dir)/somewhere/$(zipfiles).war.$(sys.uqhost)","$(sys.policy_hub)"),
file_select => exclude("restart.tomcat.$(sys.uqhost)"),
classes => if_repaired("$(allwars)");
I'm using a method because the same thing needs to happen to all war files that
come in -- delete the existing directory. I have two files that need special
handling in that they need to be unzip'd and into different locations.
Even if my approach is flawed I don't see why cfengine is only calling the
method twice when all members of the slist are reported as being activated as
classes upon copy. Equally bad is the seemingly erroneous invocation of the
commands: promises as shown in my first post.
I should have noted - I'm using cfengine 3.2.1 community on CentOS 6.0 x64.
Thanks,
F
