There were some other changes, which I'm putting into the changelog:
* New upstream release supporting custom graphs (LP: #306360)
- PATH is now set for scripts in script execution (LP: #257018)
* debian/landscape-client.postinst: Work around chfn/system user problem
by not specifying a --gecos (LP: #238755)
* debian/landscape-client.logrotate: logrotate no longer reports spurious
errors when the client isn't running (LP: #271767)
I'm not sure what type of detail you want to know for the various code
changes, so I'll try to be thorough. I'm looking through the entire diff
from the current intrepid version to this new version to write this list
of changes:
In addition to the changes above, the feature of custom graphs required some
changes:
- The client now sends a list of the types of messages that it can
accept to the server. This is to allow the server to determine whether
any given client will support a particular feature. For example, it's
used now to determine if the client supports custom graphs before
sending a message to the client.
- In order to thoroughly support the previous point, we had to change
the code that handles messages (in the manager and monitor) to tell the
broker which messages that it handles. This involves a new dbus call to
the broker. The broker itself now maintains a registry of handlers for
messages instead of doing ad-hoc message introspection when handling a
message so that we can know which types it handles.
- This accepted types stuff has a minor optimization so that the client
doesn't have to send the full list of accepted types on every exchange
with the server; the server keeps the list of accepted types and sends a
hash of all of them to the client on every exchange; the client only
sends the full list again if the hash doesn't match its current list.
- Since the custom graph code uses a lot of same functionality as the
script execution code, the script execution code was refactored to allow
reuse of the same code. Methods were refactored into smaller bits for
easier reuse and some class hierarchies were restructured.
- The custom graph feature is actually being made available as a part
of the script execution plugin: so if the user already has
include_manager_plugins = ScriptExecution in his configuration file,
custom graphs will Just Work. This also drove some of the refactoring in
the script execution code (scriptexecution.py).
- A new "manager.database" sqlite database was added to
/var/lib/landscape/client/ to store custom graph-related data. It's
called "manager.database" because it's not actually restricted to custom
graphs, but will be used for any other data storage needs of the
manager. custom graphs is just the first user.
- Of course, new unit tests were added and existing unit tests were
updated for all these changes.
As for non-custom-graph related changes:
- An accidentally duplicated method in the load average plugin was
removed
If you'd like something more thorough than this, or just some
clarification of specific issues, please ask.
I'll attach a branch shortly for jaunty.
