[Scons-dev] Upcoming switch of the Node class to slots...

[Dirk Bächle]

Hi there,

here's the next little step towards the version 2.4 of SCons, which is planned to contain the switch to using __slots__ for reducing 
the overall memory consumption. I've rebased my changes against the current trunk (default) of the main repo, and pushed the 
resulting changes to my "experimental" SCons repo. Note, that this branch is not planned to get directly merged into the main 
repo...it's just a preview/rebase for developers (I'm thinking mainly at Jason for Parts, and Ivan for PlatformIO) that might want 
to check for collisions with their tools/extensions.
So, if you fall in this category too, or simply want to test the changes against your current project, you can download the branch 
like this:

   hg clone http://bitbucket.org/dirkbaechle/scons_experimental -r switch_node_to_slots

. Make sure that you execute this in a clean directory, such that your basic SCons repo doesn't get mixed up!

If you are interested in the exact diff for this patch, the single commit above might be too big to chew on for you. Then, looking 
at my original development branch

   hg clone http://bitbucket.org/dirkbaechle/scons_experimental -r reduce_memory_footprint

, containing all single debugging/fixing/amending steps I did along the way, might give you further insight. If everything else 
fails, just ask. ;)

Please also take into account the mail

   https://pairlist4.pair.net/pipermail/scons-users/2014-July/002734.html

, where I described the planned changes on the Node API level.

That's it for now, I guess. Happy testing!

Best regards,

Dirk
