Local best cli runs on master but no other branches for lwc-example about best

[manuel-jasso]

Update: it looks like the name of the local branch doesn't matter, I changed my foo branch to track github/master and then yarn start worked fine! 🤷🏻‍♂️

This is my setup:

manuel.jasso@manueljasso-ltm ~/dev/github/best/packages/lwc-example (foo)
$ git branch -vv
* foo    0c1ef01 [github/master] feat: rewrite of Agents, Hubs, Remotes and Algo (#217)
  master 0c1ef01 [github/master] feat: rewrite of Agents, Hubs, Remotes and Algo (#217)

So best cli fails unless the current branch is tracking master on the remote.

I can't seem to reproduce this, when I try to run the lwc-example benchmarks it works fine.

I tried both in master and in a brand new branch that i just created, both worked fine.

Could there be something weird in your git config or setup? It seems that Best cannot read your git configurations properly.

[manuel-jasso]

I tried a fresh checkout of best repo and the condition is that the current branch has to be tracking something that is not [origin/master], this is my fresh setup (do this while on master):

git branch --track bad
git branch good
git branch -vv
  bad    0c1ef01 [master] feat: rewrite of Agents, Hubs, Remotes and Algo (#217)
* good   0c1ef01 feat: rewrite of Agents, Hubs, Remotes and Algo (#217)
  master 0c1ef01 [origin/master] feat: rewrite of Agents, Hubs, Remotes and Algo (#217)

best runs fine on branch good (which tracks nothing) and branch master (which tracks [origin/master]) but fails on branch bad (which tracks [master])

But given the conditions, this is a low priority issue because there is a workaround.

[jasonsilberman]

Are you saying that the issue only happens when you have multiple local branches pointing to the same remote master?

[manuel-jasso]

Mh, no, even one branch causes the error, I just pulled new master from best and these are the simplest repro steps I was able to come up with:

Do this while on master (after a fresh build):

git branch --track bad
git checkout bad
cd packages/lwc-example/
yarn start

This yields

I was able to reproduce as well. I think I am understanding this better now.

So this is happening when you create a local branch that tracks another local branch.

I am un-aware if this is very common behavior or not, as I have never needed to do this. I will see what I can do to figure out a fix though.

[manuel-jasso]

Thanks, I know tracking a local branch makes no sense, this was just my simplest repro steps, I saw this error without tracking a local branch but I don't remember what I did, my hope is that the scenario will help you identify a problem which is not specific or related to tracking local branches. And like I said before, there is a workaround so this is not a high priority.
