Hi,
The changes look very good.
I have a question regarding start/stop in Replica class. Why do not
you use the function self.agreement.schedule(agmdn,
interval='start') and self.agreement.schedule(agmdn, interval='stop') ?
I will change it to use schedule().
about the function 'agreement_dn(basedn, other)' why not putting it
into the Agreement class ?
Note that it uses the functions 'agreements' that is Replica but I
would expect it to be in Agreement class as well (renamed in 'list' ?).
Yes. I think I will change the names also, to pause() and resume().
I think the following methods should be moved to the Agreement class:
check_init start_and_wait wait_init start_async keep_in_sync
agreement_dn (rename to "dn") agreements (rename to "list") (also, is
it a problem that we have a method name "list" that is the same as a
python keyword/built-in?)
Hi Rich,
Yes that is good. When fixing
https://fedorahosted.org/389/ticket/47590 I noticed that with the new
Agreement class these functions also needed to be moved. I opened
https://fedorahosted.org/389/ticket/47600 for that. 'dn' and 'list'
are very good.
When eclipse was complaining with names (function or variable) same as
built-in keyword, I tried to change the name. Now I like 'list' name
and it was not a problem with self.replica.list(), so I would vote to
use 'list'.
New patch attached
regards
thierry

thierry
