attach source to an existing module

[gavinking]

So I made the mistake of uploading this module without a source jar. There's nothing at all wrong with what I uploaded except for the fact that now I can't see the source or docs in my IDE unless I manually copy the source jar into my local repo.

So I think we need a way to add source to an existing module when it's missing.

@FroMage Help! 😳

I think it would be okay to allow this. The same with documentation. They are both elements that won't change the workings of the code so the fact that some people might not have a source jar or no documentation while others do is not a problem.

We might even consider doing this for missing code artifacts (you uploaded the CAR but you forgot the JS files), but in that case we do have the problem that it could cause unexpected behaviour ("hey, it says it can't find "foo.js" -- "Dunno, works fine here")

I'd like to agree with @quintesse, but isn't there an "expires never" cache strategy? It's a nice property of ~/.ceylon/cache that I can always trust artifacts and never have to manually delete stuff or start over.

The same, but perhaps even more importantly, for mirrors of Herd.

As Herd grows, there's also the opportunity for vandalism, if someone rage quits their job or something and decides to mess with doc artifacts on their way out.

Immutability is good.

I think you'd always want a new version for that.

Yes, that's what I said when some people might see sources or docs in their cache while others wouldn't.
But for those elements I don't see how that would cause any problems. Some people wouldn't see sources or docs in their IDE for example while others would. That must be better than 100% of them not seeing any sources or docs.

And about vandalism, we can't prevent that anyway. A rage quitter can still upload a messed up new version. In this case they could mess a bit with docs and sources and only if they weren't there in the first place! Which is an uncommon situation. Again not something I'd worry too much about

I'm still not 100% convinced, but I can at least see much more possibilities for real problems so I think I'd agree here. Still it's something worth thinking about. Forcing people to adjust their workflow, publish a new version, just because they forgot to upload something is a bit crappy (I'm not talking about overwriting something that was already uploaded, in that case you must indeed always make a new version).

People wouldn't use the version w/o docs; they'd use the replacement version, and everyone would have the same experience (easy to troubleshoot).

That misses my point. They wouldn't be breaking something that people already depend on.

only if they weren't there in the first place!

Ok, that would definitely help. But still not worth it IMO. If you let people fix their mistakes, they'll make more mistakes, and early downloaders and mirror-ers will continually have bad experiences.
