Description (last modified by jdemeyer)

Reported by Justin C. Walker on sage-release (scroll down the thread for replies):

Upgraded from 4.5.3.a1, w/o problems.  Ran 'ptestlong', and one test failed.  Failure noted below.  I reran the test by hand and it passed.  Mac OS X, 10.5.8, Dual Quad Xeon.

Near the top of sage/interfaces/ is a possibly relevant note:

BUG -- currently non-idle PSage subprocesses do not stop when
\sage exits.  I would very much like to fix this but don't know how.

Is this still relevant after #12415?

comment:3 Changed 9 years ago by roed

  • Component changed from doctest to interfaces
  • Owner changed from mvngu to was

I don't think this has to do with doctesting...
