Re: Reviews

Hello,

Thanks for opening the discussion.

The board worked on a procedure introducing module maturity levels, and it involved lowering the barriers to merging.
Maintainer roles and ocabot ale tried to improve this.

Having active maintainers is really important for things to work, so I personally appreciate your suggestions.

Food for though, I recently found this an interesting read, and I wonder how close we could get of it.

Hi all,

For years, OCA has a big problem with unmerged PR's.

Also, even if there are 2 reviews then PSC's generally don't respond to 
merge requests.

The answer has always been "let's review more" or "Let's use 
gitaggregator and so we can use unmerged PR's".

But why don't we try something more radical:

- Let's write a script to assign "maintainer" role for all modules to 
the person who committed the oldest/original version of it

- If maintainer does not respond to a ping longer than 1 month he loses 
the maintainer role, which then changes to the default maintainer that 
is set for the full repo.

- Let's require only 1 positive review from now on. After that the 
maintainer can merge.

--> I don't think that having 2 reviewers is always necessary and it 
also does not prevent bugs from being merged - this happens anyway. I 
used to have high trust of merged OCA modules but after seeing some 
quite ugly bugs and incomplete work being merged I am starting to think 
that maybe the quality of the unmerged stuff is not that bad as compared 
to what is actually merged. The maintainer can prevent really bad 
changes from entering, by just closing the PR.

Tom

      Such fw-port tool exists somehow, but in local, thanks to Sébastien Alix:


      But theory is one thing, and the other is the reality: most of the fw-ports will fail due to pre-commit and black, different code due to version changes, refactorings... Automating the creation of the PR simply won't work, as if it's not satisfactory, or requires extra work, you won't be able to push to the fw-port created branch.

      Instead of having a lot of tools, which is not bad, IMO you should instead involve more and more of your people in PSCs and as maintainers inside your organization, or spread the adopt a module campaign for more casual contributors, trying to involve them in this.

      Let's take for example Firefox.

      Firefox has the desktop product, and it builds in different platforms: Linux, Windows, Mac... How to handle that? They have a build system that applies conditionals ("if", "case" and similar) to produce the platform-compatible artifact. Usually this is a Makefile, but there are other systems for the same. Result: single code base, multiple platforms.

      However it also has Android and iOS versions, which are almost completely different. They share some essential concepts, but code bases are split. This is more complex to handle, but they end up supporting these extra platforms too. Result: split code base, single platform.

      As you can imagine, the desktop product is more maintainable.

      Now, OCA. Our products are, mainly:
      1. Addons.
      2. OpenUpgrade.
      3. OCA tooling.
      We only follow the "single code base, multiple platforms" approach in OCA tooling.

      For OpenUpgrade, we use "split code base, single platform", and it would be impossible to change that.

      And for addons? The platforms they run on are different versions of Odoo. I always believed it's possible to have a single code base, but that's a dead discussion and simply won't happen, so the best we can do is improve what we have. And what we have is "split code bases, single platform". And IMHO the way to improve it is a fwbot, just like Odoo does.

      Maybe a good theme for a team at this year's online code sprint?

      Indeed.

      As a reminder, OCA Days are coming up, and there will be the usual code sprint.
      It would be nice to have a group working on OCABot improvements.
      This can be to work both on code or process change proposals.


      A question that popped to my mind yesterday is one for the board - has it ever been considered for OCA to pay people to fulfill maintainer roles within the organisation? Money seems to be something thats available, and the spending of money on OpenUpgrade has been a great things throughout the last years also.

      It has been discussed.
      The feeling was that doing so it would work against the volunteer spirit of the community, and could break volunteers motivation.
      Investing on better tooling would be better.
      For the record, there has been an initiative for bounties, where people could publish a bounty, awarding a payment for a task, but it didn't get traction.


      Thanks
      Daniel

      Wow, i must say that everyone comes up with much better ideas than I had originally.

      I hope more people keep contributing to this thread since I do think it's a big issue. I'm also interested to know how other open source projects are handling this. And perhaps we can look at the "IT projects LLC" repos for inspiration - even though i dont understand their system, it looks pretty happy with all the icons. A "important bugfix" being represented by an ambulance.

      +1 for the bw/fwport bot

      - It would be nice to have a new convention to tag a PR with a label like "Review it in 30 seconds" [R30] when it is a basic/simple/quick fix add/fwd that does not require you to soak up the functioning.
      - It would be nice too that a bot automatically tag an issue/PR with a github label based on the issue/PR name or simply the target branch name : eg: [12.0] -> image.png

      Yep. They do it because they can handle it. The question is: why we can't?

      There are many reasons, but the one that I find most important and easiest to fix is that we need a bw/fwport bot.

      That will make maintenance pleasing, so we'll have more maintainers.
