gkossakowski · 2014-10-09T12:29:57Z

@Duhemm, would you like to have a look?

Duhemm · 2014-10-09T12:41:45Z

I've discussed this issue with @xeno-by a few days ago and I think this is a bug in scalamacros/paradise.

I have a fix that simply ignores TypeTrees where tpe == null.

Shall I open a PR with it while the bug is not fixed in paradise ?

gkossakowski · 2014-10-09T12:44:01Z

Hmmm, I'd prefer not clutter our code too much if not absolutely necessary. If this is a bug in the paradise, I'd prefer it being fixed there. @xeno-by, what's your take on this?

gkossakowski · 2014-10-09T12:44:34Z

@Duhemm, also is there any work-around for people using paradise. E.g., manually setting tpe for TypeTrees?

Duhemm · 2014-10-09T12:52:27Z

That's why I didn't share this patch...

Not that I know of. I quickly showed Duhemm/macro-annotation (not sure about the name, I'm on my phone) to Eugene when I first encountered this bug and he couldn't tell me how to fix it either (my first guess was that the problem came from my macro).

xeno-by · 2014-10-10T12:09:14Z

This ExtractDependenciesByMemberRefTraverser, what does it traverse? Where does it get the trees to look into?

I don't remember this off the top of my head, but it might very well be that after expanding macro annotations, macro paradise saves the expansion into MacroExpansionAttachment. Naturally, the attachment will be unattributed, so if someone looks into it, they might find empty TypeTrees there (signifying types that haven't been specified by the user that will need to be inferred).

xeno-by · 2014-10-10T12:09:41Z

@MasseGuillaume Disable name hashing, and you should be fine - crashes only happen when name hashing is turned on.

dragos · 2014-10-15T10:24:01Z

Here's a debugging session of what's happening. Notice that all trees have null types at the time when dependency extraction gets to run. @xeno-by, is there some cleanup phase in macro paradise that should run before dependency extraction?

xeno-by · 2014-10-15T14:56:08Z

How does SBT get hold of new hello().macroTransform(...)?

dragos · 2014-10-15T15:15:27Z

Probably by handling MacroExpansion. @gkossakowski can explain better what he's after.

Duhemm · 2014-10-15T15:24:32Z

Macro paradise does not attach any MacroExpansionAttachment, so it won't get in this block.

@xeno-by we discussed the origin of this problem last week, do you think that my previous "analysis" of the problem was wrong ?

xeno-by · 2014-10-15T20:00:43Z

It looks like I actually misled you. Paradise does attach this attachment, because expansion of macro annotations is retrofitted onto the infrastructure that expands def macros (hence the new annot().macroTransform(...) thingie in the code).

What I can do is not attaching anything when expanding annotations. That shouldn't be very hard to implement in paradise. Alternatively, we can keep the attachment, so that it's available for anyone who might want to analyze it and then in SBT you could insert a check: if a tpe of the attached tree is null, you disregard it and don't recur into its children. What would make more sense?

dragos · 2014-10-15T20:56:59Z

@Duhemm, the stack trace is pretty clear on that.

@xeno-by, my preference is to harden Sbt in the event that macros can break this assumption, and it would also fix #1593, which so far isn't directly linked to a macro. But @gkossakowski has the final say.

vigoo · 2014-10-24T10:31:01Z

Possible related issue: vigoo/scalafxml#13

xeno-by · 2014-10-24T10:32:13Z

Allright guys, is there any news? What do we do about this?

gkossakowski · 2014-10-24T16:55:23Z

@xeno-by, regarding your comment above. Do you attach untyped trees as an MacroExpansion attachment?

xeno-by · 2014-10-25T07:28:55Z

@gkossakowski Yes. Arguments to macro annotations are untyped, so that's what's attached.

Duhemm · 2014-11-27T10:30:06Z

Hey guys,
Since this is not a bug in macro paradise, should we add this check in sbt ?

dragos · 2014-11-27T10:57:33Z

I think we agreed we should add a null check, but nobody did it so far (maybe the discussion was on #1593). I promise to review the PR if you open one :)

In some cases the dependency extraction may encounter a null `TypeTree` (eg. arguments of macro annotations that are untyped). In such cases, we simply ignore the node. Fixes sbt#1593, sbt#1655.

ASchmidt84 · 2014-12-22T17:33:38Z

I have still the same issue on using 0.13.5 and @sfxml 😢

dragos · 2014-12-22T18:22:27Z

I don't think there's a release containing a fix for this one yet (this bug was reported on 0.13.6 anyway). @jsuereth or @gkossakowski do you know when will this fix be released?

ASchmidt84 · 2014-12-22T18:32:58Z

Also the workaround:
https://github.com/milessabin/shapeless#building-shapeless isnt working. It is not important to solve the complete problem if their exist a working workaround 😱

Do someone use now sfxml and why this work at his code?

gkossakowski · 2015-01-12T18:12:40Z

@IntelligyScience, if the workaround doesn't work then I think you are hitting some different problem.

gkossakowski · 2015-01-12T18:23:22Z

According to milestones, 0.13.8 should be around the corner: https://github.com/sbt/sbt/milestones
I'll let @jsuereth have a final say on this.

In some cases the dependency extraction may encounter a null `TypeTree` (eg. arguments of macro annotations that are untyped). In such cases, we simply ignore the node. Fixes sbt#1593, sbt#1655.

MasseGuillaume · 2015-01-28T22:57:45Z

@gkossakowski same error with 0.13.8-M2

eed3si9n · 2015-02-02T18:35:45Z

This is now fixed via #1754

MasseGuillaume · 2015-02-02T20:05:03Z

@eed3si9n cool can you release this under v0.13.8-M3 ?

xeno-by · 2015-02-02T21:48:28Z

\o/

eed3si9n · 2015-02-02T21:49:19Z

0.13.8-M3 should be out today.
