Initial draft of Re-engineering Page
= Re-engineering OP25 =
Since we first started on OP25 there has been a long hiatus during which GNURadio has evolved and this has caused a lot of problems. This page is the top-level for the re-engineering effort.
Re-engineering and Refactoring goalsThere are a number of top-level goals for this exercise. Most obviously we want the code to work on GNURadio 3.6 but there are many subtasks:
- Move to cmake for the build.
- Rename components consistently using the new namespace rules.
We can use the new - [RefactoringPage Refactoring so we have top-level encoder/decoder blocks but expose lower-level blocks (e.g. P25 correlator, P25 error corrector, IMBE vocoder, etc.) and make use of new features as appropriate.]
- Remove dependency on obsolete interfaces.
- Remove dependency on problematic external code for build: * Remove dependency on IT++ (write our own error-correction code instead). * Remove dependency on Frank's demod (pretty much done).
- Revise the p25cai encapsulation protocol (the radiotap-like structure sucks) and ensure that OP25 and wireshark use it properly.
To keep the work to a reasonable minimum we can focus stage one on just the core blocks and use GRC to implement a transceiver and receiver.
TicketsWork will be managed using the trac ticket system. Every re-development activity will have an associated ticket so we can track progress.
Source CodeWe'll make the work-in-progress available on the trunk of the normal OP25 repository. For now we'll just use a new "refactoring" subdirectory to act as the top-level of the re-engineered codebase.
=== Unit Tests ===
Open questions:- Use Boost::Test to write unit tests?
- Require all blocks to implement make check.
Have them call the "real" Boost::Test unit tests or do something else?
This wiki page is intended to be the top-level page for the re-engineering exercise. If we need to work on a proposal we can open a shared wiki page to capture the idea and discuss it via the e-list.
