updated: LTS: 19

[ncaq]

The work was done mainly to support the new version of persistent. We have achieved some success, but there are a few things left to be done.

@snoyberg By the way, who is the maintainer of this project now?

Things left undone

We were not able to maintain the Example'. For some reason, the newmkServerSessionDefs` works in the test project. I get a Kind type mismatch error when I rewrite the Example project in the same way.

I could not remove connEscapeName from TestImport in Example. I couldn't find any trace of a commit where connEscapeName was removed from persistent. I have no clue how to rewrite it.

Policy concerns

I have set up a policy to create a new type alias and specify a new HaskellName, but I have no idea how to change the policy. It might be better to expand Template Haskell to some extent and rewrite the arguments.

[snoyberg]

No one is really maintaining this right now. Would you be interested in taking it over?

[ncaq]

@snoyberg We need this project for our product. So if there is no maintainer, I will have to maintain it. I have no experience in maintaining FLOSS for other authors, so I don't know if I can do it well. But I have no choice but to do it, so I will take on the task. I would like to be a maintainer.

On a different note, do you know who to ask about TestImport not working because connEscapeName has been removed from persistent? Should I ask the persintent maintainer? I'm still not sure what would be appropriate to rewrite Yesod's newly created sample project, even if I were to fix the fact that it is still lts-16.

I would like to be a maintainer.

Awesome! I've invited you to this repo. I can add you on Hackage as well if you tell me your Hackage username and the packages you need to be able to maintain.

Should I ask the persintent maintainer?

Yes, that probably makes the most sense, I'm not familiar with the changes.

My Hackage username is ncaq and email ncaq@ncaq.net .

I didn't quite understand what you meant by " needed packages," but it looks like the only thing I'll be tinkering with directly, rather than in PR form, will be around serversession for a while.

[snoyberg]

Cool, I've added you as a Hackage maintiner for serversession: https://hackage.haskell.org/package/serversession/maintainers/.

It seems to have stopped working because CompositeRef stopped doing its job. Constructor CompositeRef for ReferenceDef is no longer used · Issue #1285 · yesodweb/persistent

[ncaq]

It seems that data without PRIMARY is difficult to handle with the new Persistent. I guess the best I can do is to specify key as Primary and allow automatic migration.

[ncaq]

I think we have done most of it. On my next working day, I will check the development version of our product to make sure there are no problems with functionality, and if there are no problems, I will merge it and release it.

[ncaq]

After a little research, it seems to be working properly, so I will merge and release it.
