feature: git-ubuntu find

[Dmitrii Shcherbakov]

At times it is useful to find if a repository is present in usd-import-team project by a substring or regex.

git-ubuntu find udev

git-ubuntu find '.*udev.*'

Not critical, but would definitely make life easier sometimes.

Interesting idea. It's really a Launchpad query, not related directly to the git-ubuntu tooling. I mean, worst case, try to clone it and if it fails, then ... it's not there :)

At the same time, our plan is to ramp up to all source packages during this cycle and keep them all up to date, at least for main. At which point, I'm not sure we'd want this subcommand.

I'll mark it as wishlist and future for now. (right now, we're focused on the importer algorithm and being able to import all of main).

Sometimes a package name is different from source package name, hence when you do

dpkg -S <somefile>

it is not always clear which repo to look for.

Over time you learn them all but it's nice to grep instead of clicking through :^)

Thanks for that work - I use it quite often and really appreciate the effort. It became much easier to find relevant code to me.

[Nish Aravamudan (nacc)]

Ah! I misunderstood your request -- I thought you were asking for a CLI subcommand to check if something had been imported or not.

Instead, you are looking for (possibly) a binary -> source mapping, which is described in LP: #1707325.

[Dmitrii Shcherbakov (dmitriis)]

Thinking about it now, it may be even more useful this way.

If a binary -> source search fails, there's no such repo in usd-import-team so you have to go and find an upstream repo manually or pull a source archive.

The original request may still be valid as sometimes you don't do dpkg -S <filename> to determine a package name.

Good idea!

What if, upon failure to find a particular source package on "git ubuntu clone", we did some heuristic guessing and if we get a hit, suggest in a "X is provided by source package Y\nDid you mean: git ubuntu clone Y?" type error message? The heuristics could include some combination of binary package namespace search, substring match, and "dpkg -S $(which ...)".

[Dmitrii Shcherbakov (dmitriis)]

Could be useful too.

Sometimes you're just searching through so you may want to be explicit
right away.

For anyone else reading this... I realize this is a feature request in the future milestone on git-ubuntu to be able to grok either and perhaps search with a list option for more discovery...

but, bin2src from chdist is meant to solve this problem in general. You might be able to integrate that into your workflow right now to accomplish what you would like.

Just a suggestion.
