Re: [OpenWrt-Devel] alternative for pyserial+python-mini
It's still turned off. But it was turned off again, once it was moved to Github. There was a more recent discussion here: https://github.com/openwrt/packages/issues/474 [ Quick answer here: yes we can precompile bytecodes at build-time and ship those instead ] So, .py vs .pyc vs .pyo is a recurring question. .py - python source file .pyc - compiled bytecodes (from .py file) .pyo - compiled optimized bytecodes (not sure yet what optimized means) Which of these 3 formats should the Python libraries use to be packaged ? Opinions differ here. At the time I packaged python, it seemed logical that .py files should be it; that's how most how distros get Python packaged. But then, .py files automatically generate .pyc files that fill up RAM or Flash, so that was disabled [ for the OpenWRT case ]. But now that I re-think about it [for the OpenWRT case] maybe changing to .pyo would be better, since it would optimize performance (size speed). And then the source files could be re-packaged to python-sources [ or something ] . One proposal was a bit backwards in logic: i.e. package Python libs as are now, and package Python bytecodes in additional+installable packages. My main preference here, is that I wouldn't want to give up the convenience of having Python source files, which is why I prefer[ed] to sacrifice performance in the first place. [ And then, nobody complained yet loud enough to change this ]. So, this python packages to bytecode conversion + python sources packages would be an interesting idea to do.

Hi, I have just created a pull request for an updated version of pyserial. https://github.com/openwrt/packages/pull/1485 Regards Micke Prag 2015-06-26 15:26 skrev Alexandru Ardelean: Ah, since that email, python became: - python-base - just the minimal to have a python interpreter running - python-light - is a dynamic package; it's python (full) minus all other python-codecs, python-compiler, etc - python - full python install, minus a few stuff I considered that could be stripped [to reduce size], like tests [per module], some python-tk/tcl [GUI] libs The idea of python-light is that, whenever you move a Python built-in module from python-light into a separate package (like python-codecs), python-light gets lighter. The mechanism is fairly dynamic; you just need to add a new 'python-package-xxx.mk [3]' file with some basic Makefile rules, and that's it. People can choose to install python-base if they need like really-really-really-really basic python (a = b + c and maybe some other syntax). Then they can choose to install other optional packages. But for most cases, maybe python-light would be sufficient. The above is also true for python3.
