While the Louie system operated on weakrefs for the callback
functions, the priority list wrapper did not. This difference led to
weakrefs to callback functions being compared to strong references in
list element operations within Louie's disconnect method, so that
handler methods were not disconnected from signals.
Converting the receiver to a weakref then allowed Louie to operate as
normal, which may include deleting and re-appending the handler method
to the receivers list. As ``append`` is a dummy method that allows the
priority list implementation, the handler method is then never added
back to the list of connected functions, so we must ``add`` it after
``connect`` is called.
Also included is a testcase to confirm the proper disconnection of
signals.
- Add copyright headers to files that did not already have them
- Update the year to the last year the file was modified in files with
existing headers.
- Keep track of logged exceptions inside log_error itself.
- signal: log the exception, if there is one in the finally clause of
the signal wrapper; this will ensure that the error will be logged
closer to the command that originated.
- entrypoint: use log.log_error for top-level error logging, rather than
the entrypoint logger directly; this will ensure that errors are not
repeated unnecessarily.
- Log CTRL-C message at zeroth indent level to make it easier to see in
the non-verbose output where it occurred.
- Workload's update_result stage has now been broken up into two parts:
extract_results and update_output. This is to allow the assistant to
pull output from the target in between the two stages.
- Updated assistant implementations for Linux and Android targets from
the exisiting code.
- Extended target descriptor code to handle assistants and their
parameters as well.
- Updated the target manager to actually make use of the assistants.
- Fixed up some of the signal map for instrumentation
- Changed how priorites are specified -- no longer method name prefixes
but dedicated decorators, including an easy way of specifying a custom
priority level (no longer need to manually connect signals)
- Updated ExecutionTimeInstrument to work with the new system
- Also removed some dead code
Changing the way target descriptions work from a static mapping to
something that is dynamically generated and is extensible via plugins.
Also moving core target implementation stuff under "framework".
