PyBombs install maint branch from fresh

GNU Radio
1

Dear Sirs,

I am performing fresh gnuradio installation using pybombs.
Pybombs install master branch by default.
How to make pybombs install ‘maint’ instead?

Act@rsLAPTOP: ~/download/pybombs $ git checkout maint
error: pathspec ‘maint’ did not match any file(s) known to git.

This is not how you use git; you need to give it a remote branch to
track first. Also, if you checked out ‘maint’ on pybombs, it wouldn’t
necessarily check out ‘maint’ on any SW package it’s trying to install.

I assume you’re trying to install GNU Radio maint, right? I guess one
way would be to modify the gnuradio.lwr recipe, change the default
branch to maint.

Thanks.
yes, I am trying to install GNU Radio maintenance branch.
I will change the gitbranch of gnuradio.lwr recipe to ‘maint’.
Does this means the uhd.lwr also need to be ‘maint’, or can just be
‘master’ as default?

Martin,
You are probably right we should track maint by default at this point.
I
think it’s worth adding a Pybombs environment question about which
branch
to track during initial setup for those that prefer to track master
however.

Tim,

idea:
pybombs install package
gets the default branch as in the recipe,
pybombs install package%awesomefeatures
gets the awesomefeatures branch.

That would allow people to specify they want UHD maint, GNU Radio
v3.7.4, and gqrx master, if they really want to.

Greetings,
Marcus

I agree with you.
It is quite strange that the “build-gnuradio” script installs ‘maint’
branch by default, whereas pybombs installs ‘master’ branch by default.
This is lack of consistency.

One of the problems with allowing this kind of customization is that a
single set of pybombs recipes is generally intended to represent a fixed
set of versions / branches as far as configuration management.
Supporting additional branch combinations is kind of explosive in terms
of new combinations of supported packages/versions. That said, master
is kind of a moving target. The hope was to have a set of recipes that
tracks master everywhere for the most part (for developers that want
this), and then have numbered known good sets of recipes that track for
instance 3.7.3 or 3.7.4 with known good OOT modules at the time (for
more stable OOT development or pure users). However this is a lot of
time/work to set up and constantly test / release so thus far we haven’t
really been doing that half - The versioned releases are to some extent
already covered by binary packages -
That said, we can always throw this feature in with a danger untested
version combination caveat …

Thanks.
Just curious, does below statement still apply …?

We provide UHD and GNU Radio binary installers for Ubuntu and Fedora
users.
There are two choices:

  • Unstable: Built off of GNU Radio’s master branch and an
    unstable
    UHD install, which includes bugfixes and new features.
  • Stable: Built off of GNU Radio’s maint branch and a stable
    UHD
    install, which only includes bugfixes since the last major release.

These GNU Radio installers will only work with their corresponding UHD
binary. If you use an unstable UHD binary with a stable GNU Radio
binary
(or vice versa), you will not be able to use any gr-uhd features.

Ah well, consistency with the slowly aging build-gnuradio was not the
intended purpose of having pyBOMBS. build-gnuradio is the result of an
ongoing effort to bring a stable GNU Radio to a lot of platforms
without having people worry too much about getting all the
dependencies and the build process right.

PyBOMBS had this in mind too, but also was meant to provide a
comfortable framework to get OOTs and dependencies installed in a
flexible manner; thus, using master made a lot of sense, so the latest
and greatest OOTs could run. However, since maint is so close to
master, and PyBOMBS has hit the mass market, switching to maint does
sound very clever.

Agreed, that’s why I like the idea of GR being maint by default (so
that dependencies might not change that easily [hoping that maint is
always tested with the minimum required versions]) and letting users
who might want to risk the breakage just choose their version to their
liking – obviously, if you take a different version than the recipe
maintainer thought would be right for you, you’re leaving the safe
path, and no one can really help you there if you have funky version
problems.

Marcus

Thanks for clarification.
This makes a very good sense.
