[Rock-dev] autoproj snapshot not working on detached HEAD?

Discussion:

Hi,

it looks like autoproj snapshot is not working on detached head state.

Let's say I need to search in the git history of a couple of packages to
get back to a working state for a demo. I am searching by checking out
commits manually until I found the commits of all effected packages that
work together.

By checking out commits manually, I will get into the detached HEAD state:

$ git checkout 995e018
-> You are in 'detached HEAD' state. [...]

To save the current state of all packages, a snapshot is created:

$ autoproj snapshot demo_working

Now the demo_working/overrides.yml will pin the commit where the HEAD is
pointing to (e.g. 5e2e3a259) instead of the commit that I chose manually
for the package (995e018).

Is this the desired beahviour? In my opinion a snapshot should store the
current state of all my git repositories meaning that I can also select
commits manually.

Regards,
Christian

I doubt that this topic belongs to stackexchange. People already
complained about asking questions about the push url in autoproj on
robotics.stackexchange.com.

This is maybe a bug and worth a discussion about the behaviour of
autoproj snapshot. The target audience of this are developers, not
users. Therefore I think that rock-dev is the right place.

Christian

Hi,
Why pople complaining regarding your question, exactly this push_to
question is a good example for the use of stackexchange.

And This question is similar, maybe we can discuss this as a feature
request, but so far this is a straight forward question...

Best,
Matthias

question is a good example for the use of stackexchange.

Just look at the comments of
http://robotics.stackexchange.com/questions/3091/how-to-overwrite-default-git-source-in-autoproj

"This is not a robotics-related question. [...]"

Post by Matthias Goldhoorn

Yes, this is the question if the behaviour is desired and the answer to
it determines if it is a bug (not desired behaviour) or if there should
be a feature request if this is the currently desired behaviour.

I think it is a development related question and that we should not spam
stackexchange with this kind of questions.

Is there a guide on where to ask what kind of questions?

Nevertheless, I asked the same question about the behaviour of autoproj
snapshot on stackexchange.

Regards,
Christian

I've replied to them about autoproj being part of a robotics framework.
We'll see what happens.

IMO this is a user question (you use autoproj snapshot and have a question
about its behaviour). If there is really a need about further discussions,
then it can be moved to the relevant package's bug tracker.
