* A flag `--keep-going / -k' to keep building goals if one fails, as
much as possible. (This is similar to GNU Make's `-k' flag.) * Refactoring to implement this: previously we just bombed out when a build failed, but now we have to clean up. In particular this means that goals must be freed quickly --- they shouldn't hang around until the worker exits. So the worker now maintains weak pointers in order not to prevent garbage collection. * Documented the `-k' and `-j' flags.

Sets the maximum number of build jobs that Nix will perform in

parallel to the specified number. The default is 1. A higher

value is useful on SMP systems or to exploit I/O latency.

|

Keep going in case of failed builds, to the greatest extent
|
||||
possible. That is, if building an input of some derivation
|
||||
fails, Nix will still build the other inputs, but not the
|
||||
derivation itself. Without this option, Nix stops if any build
|
||||
fails (except for builds of substitutes), possibly killing
|
||||
builds in progress (in case of parallel or distributed builds).
