undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (710f44fe7f9ff77d0896a250b2de52f2b4cc0a3a) \ N -- N -- N (a53f3b66d7f514295bd071871211ec82ad4d1147) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- ----------------------------------------------------------------------- Summary of changes: debian/changelog | 2 + debian/control | 3 +- etc/broker/x2gobroker-sessionprofiles.conf | 4 +- etc/x2gobroker-wsgi.apache.conf | 1 + etc/x2gobroker.conf | 5 + sbin/x2gobroker | 2 + x2gobroker/brokers/base_broker.py | 3 + x2gobroker/brokers/zeroconf_broker.py | 7 +- x2gobroker/defaults.py | 6 +- x2gobroker/tests/test_broker_base.py | 4 +- x2gobroker/tests/test_broker_inifile.py | 142 +++++++++++++--- x2gobroker/tests/test_broker_zeroconf.py | 2 + x2gobroker/tests/test_web_plain_zeroconf.py | 9 +- x2gobroker/tests/test_web_uccs_zeroconf.py | 80 +++++++++ x2gobroker/uccsjson.py | 245 +++++++++++++++++++++++++++ x2gobroker/web/uccs.py | 165 ++++++++++++++++++ 16 files changed, 644 insertions(+), 36 deletions(-) create mode 100644 x2gobroker/tests/test_web_uccs_zeroconf.py create mode 100644 x2gobroker/uccsjson.py create mode 100644 x2gobroker/web/uccs.py The diff of changes is: diff --git a/debian/changelog b/debian/changelog index b497da4..b2f1fdf 100644 --- a/debian/changelog +++ b/debian/changelog @@ -5,6 +5,8 @@ x2gobroker (0.0.1.1-0~x2go1) UNRELEASED; urgency=low Apache2 by using the mod_wsgi module. - Add Apache2 configuration for WSGI support that shows how to setup a VirtualHost for X2Go Session Broker. + - Add cmd and directrdp session profile parameters to defaults. + - Fix wrong usage of session option »cmd«, has to be »command«. - For sessions profiles with autologin enable, add a dummy key session profile parameter that triggers key based auth in X2Go Client.
