= 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 goals == There 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. == Tickets == Work will be managed using the trac ticket system. Every re-development activity will have an associated ticket so we can track progress. == Source Code == We'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? == Managing Discussions == 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.
