[PATCH] [WoK] Bug fix #217: Fixing select() waking up
by dhbarboza82＠gmail.com 17 May '17

17 May '17

From: Daniel Henrique Barboza <danielhb(a)linux.vnet.ibm.com> There was a condition in the close of the Websocket that wasn't being covered properly by the pushserver prior to this patch. The fix was to put an additional condition to close our remote socket reference when we receive no data from it, instead of relying just in the Except call to do it. While we're at it, a cleanup was made in the code to remove a condition of a 'CLOSE' message that was being sent in the first versions of the Pushserver but didn't make upstream.

[PATCH] [Wok] Add federation feature to Wok
by Aline Manera 17 May '17

17 May '17

It was primarily implemented on Kimchi project. But it makes more sense to be on Wok since the idea is to allow user add/select on which server Wok should manage. For example, the user could have a Wok installation on server A to manage server B.

[PATCH] [Kimchi] Move Kimchi specific functions from gingerbase.netinfo to Kimchi
by Aline Manera 08 May '17

08 May '17

The idea behind this patch is to eliminate the Ginger Base dependency. Almost all the functions in gingerbase.netinfo are for only Kimchi matters. So move them to Kimchi and when posible use ethtool module to provide the necessary info Signed-off-by: Aline Manera <alinefm(a)linux.vnet.ibm.com> --- control/interfaces.py | 7 +- model/interfaces.py | 37 ++++- model/networks.py | 22 ++- model/ovsbridges.py | 4 +- network.py | 434 +++++++++++++++++++++++++++++++++++++++++++++++++- tests/test_model.py | 2 +- 6 files changed, 478 insertions(+), 28 deletions(-) diff --git a/control/interfaces.py b/control/interfaces.py index 7b6127a..7aba664 100644 --- a/control/interfaces.py +++ b/control/interfaces.py @@ -37,9 +37,4 @@ class Interface(Resource): @property def data(self): - return {'name': self.ident, - 'type': self.info['type'], - 'ipaddr': self.info['ipaddr'], - 'netmask': self.info['netmask'], - 'status': self.info['status'], - 'module': self.info['module']} + return self.info diff --git a/model/interfaces.py b/model/interfaces.py index 6be4356..0532072 100644 --- a/model/interfaces.py +++ b/model/interfaces.py @@ -1,7 +1,7 @@ #

[PATCH] [Kimchi] Move Kimchi specific functions from gingerbase.disks to Kimchi
by Aline Manera 08 May '17

08 May '17

The idea behind this patch is to eliminate the Ginger Base dependency. Some functions in gingerbase.disks are for only Kimchi matters. Others are shared with Ginger and can not be rewritten using PyParted, each means they will be place on Kimchi and Ginger Base. As this code is mature enough, further changes will have few impact and the gain to incorporate Ginger Base into Ginger and eliminate a Kimchi dependency is bigger.
