Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2015-01-23 21:12:36 UTC
With high enough number of jobs (think of distcc) and large enough objects (LLVM), the post-install stripping can be real OOM-killer. I think the dangers of that much outweigh the benefits of doing strip in parallel.

I guess we need a new configuration variable to control things like this, considering that distcc basically renders MAKEOPTS useless for this purpose.

removing parallel support from prepstrip is a non-starter.  it was implemented precisely because it was a significant bottleneck.  conversely, this is the first time i've heard of running into resource limits (with the code being 3 years old at this point).  i don't see why it's specific to stripping though ... surely any process that uses a lot of memory and in parallel (like linking a lot of large objects) would cause the same failure on a resource constrained system.
