[Scons-users] error in builder_node_error

[Jason Kenny]

I see a little more details now.

I am trying to call some builders in a scanner to do more dynamic logic. ( This might be part of the problem)

I think the issue I was having was as I was retrofitting the builder, I was returning from the scanner object that had there actions finished. Scons added logic at some point to “remove” extra node data to help reduce memory foot print. It seems that as I add these node via the scanner dynamically some logic “expects” these objects to have information about the executioner ( which is now None). As it turns out the node causing this problem is the “wrong” node to return from the scanner. So removing it from the list seems to solve the issue I was reporting here.

We might want to add a fix to check if the node has a null executor, and if so report something … I am not sure what that should be however …

What's t, and what does t.get_executor() return?
Looks like it's None...

Same error… just wanting to clear up this was not Parts monkey patching stuff 😊

Hi Bill,

Working on a new builder ( hopefully will get it working soon)  I am getting an error out of SCons with this trace

scons: *** [_build/build_debug_posix-x86_64/openssl/_rpm/openssl-1.1.0-25.x86_64.rpm] AttributeError : 'NoneType' object has no attribute 'get_all_targets'
… <skipping for brevity>
  File "/home/jkenny/code/build-env/lib/python2.7/site-packages/scons-3.0.1/SCons/Builder.py", line 645, in __call__
    return self._execute(env, target, source, OverrideWarner(kw), ekw)

  File "/home/jkenny/code/parts/parts/overrides/dup_node_builder_env.py", line 71, in parts_node_errors
    if t.get_executor().get_all_targets() != tlist:


I am not sure at the moment what I did to upset SCons ( I am 100% sure I did something wrong) . However it look like there is a more serious error in reporting to the user. Have you seen anything like this before?

Jason
