Only recompile, when LESS files has changed about ember-cli-less

[gpoitch]

@martinthogersen I can't reproduce this. Only changing a less file triggers a less rebuild. Could be a problem with a specific ember-cli version? Working well on 0.1.15 and all previous versions.

I upgraded to version 0.2.0-beta.1 after writing the previous comment, and the LessCompiler still runs for every change:

file changed routes\admin\index.js

Build successful - 7793ms.

This is a known issue we have seen in the past, not an issue within ember-cli-less specifically though. Stefan is working on some logging so you can easily track down what is touching the tree, causing the cache writer to invalidate the style tree.

It may be better to open to issue in broccoli-less-single repo for tracking purposes.

@jasonmit ya, I tracked it down to sourceMapConcat invalidating the tree. I have been busy because of emberconf but @rwjblue may have time to look into it today, if not I will look into it early this next week.

@stefanpenner Can I track the progress somewhere?

[stefanpenner]

not currently, it is quite literally in every related project.

[martinthogersen]

Alright thanks. Keep up the good work 👍

[stefanpenner]

basically, I got blocked by that stupid glob/rimraf + npm issue. Now that that is resolved I can resume work. It was just wide-spread-effort because it involves updating literally everything :P

[martinthogersen]

Awesome! Does that mean that this issue is resolved?

@martinthogersen no, it still actual for me, at least, even after update to new version (

I have experienced this issue for a couple months. I think I have used the following versions of ember-cli in that time: 0.12.x, 0.15.x, 0.2.1. This was not an issue prior to upgrading to 0.12.x but unfortunately I can't recall what cli version I had prior to that.
