templater: raise error for unknown func Previously, if a template '{foo()}' was given, the buildfunc would not be able to match it and hit a code path that would not return so it would error out later in the templater stating that NoneType was not iterable. This patch makes sure that a proper error is raised so that the user can be informed. Tests have been updated.

bundle2: support bundling of empty part (with a type) Here start the work on bundle2 parts. Our first step is to be able to bundle a simplistic part that just have a type, no parameters, empty payload.

revsetbenchmark: add a summary at the end of execution The summary list timing per revset making it much more easier to compare revision to each other.

revsetbenchmark: retrieve the benchmark value in python We retrieve the output of the perf extension and print it ourself. This open the door to processing of this data in the script.

revsetbenchmark: get revision to benchmark in a function And move it to proper subprocess call.

revsetbenchmark: convert revision display to proper subprocesscall

revsetbenchmark: convert performance call to proper subprocess call

revsetbenchmark: convert update to proper subprocess call
