Also added tests for it.
Added comment to the *HierarchyPath.AsString() function,
addressing the issue of not being able to retrieve the
element when the root path is equal to the path that
is being processed.
HierarchyPath parser now returns nil when
the path is empty (instead of a string slice with one
EmptyString element).
If the prefix is set to true, when calling the AsString
method on a nil HierarchyPath, only the separator will
be returned. This avoids a nil expr error coming from
the xmlquery library.
Use the Query and QueryAll functions from the xmlquery
package to be able to handle the errors ourselves and
avoid panics.
Added an integration tes for the special case where the
xml_root_path field is left empty. Before the change it
used to trim the root element from the path slice when
attempting to retrieve a the relative path slice.
The purpose of this is to check whether RoundingDecimals was set from the fields configuration.
If it wasn't, we are going to be using the RoundingDecimals dictated by the general subsection.
The FormatCost function in cdr.go now accepts an additional parameter of type *config.RSRParser. This is
then used to extract the value from its path as opposed to always using the value of the Cost field directly.
Improved the unit test for the FormatCost function. Now it has become a table-driven test and it handles
cases when the cost is retrieved from different fields other than from the CDR.
Replace all instances of rpcclient.ClientConnector with birpc.ClientConnector.
Pass context, maxReconnectInterval, delayFunc and birpcClient to rpcclient
constructors.
Remove redundant time.Duration conversions (e.g. time.Duration(1*time.Second)
now becomes time.Second.
Add context where needed (context.Background() for tests, context.TODO()
for places where it should be passed from somewhere else).
Implement that functionality of the SessionSv1.Sleep call, in sessions/sessions
instead of apier/v1.
Make changes in utils/server.go (replacing the old rpc2 library with github.com/cgrates/birpc).
Change the way we register birpc methods for sessions in services, using a helper function
defined in engine/libengine.go.
