John Ericson	523359d133	WIP: Document the design of Nix ... The current docs are all "how to do things" and no "what is Nix" or "why are things the way they are". I see lots of misconception on the wider internet, and I also think we would benefit from a "living document" to answer some questions people currently turn to the thesis for. I think a new section of the manual can address all these issues.	2022-08-04 12:37:46 +02:00

Alex Wied	722de8ddcc	libstore/globals.cc: Move cgroup detection to libutil	2022-07-19 16:25:53 -04:00
Alex Wied	1af5d798a4	libstore/globals.cc: Automatically set cores based on cgroup CPU limit ... By default, Nix sets the "cores" setting to the number of CPUs which are physically present on the machine. If cgroups are used to limit the CPU and memory consumption of a large Nix build, the OOM killer may be invoked. For example, consider a GitLab CI pipeline which builds a large software package. The GitLab runner spawns a container whose CPU is limited to 4 cores and whose memory is limited to 16 GiB. If the underlying machine has 64 cores, Nix will invoke the build with -j64. In many cases, that level of parallelism will invoke the OOM killer and the build will completely fail. This change sets the default value of "cores" to be ceil(cpu_quota / cpu_period), with a fallback to std:🧵:hardware_concurrency() if cgroups v2 is not detected.	2022-07-19 16:03:58 -04:00

Adam Joseph	c8c6203c2c	local-derivation-goal.cc: detect unprivileged_userns_clone failure mode ... The workaround for "Some distros patch Linux" mentioned in local-derivation-goal.cc will not help in the `--option sandbox-fallback false` case. To provide the user more helpful guidance on how to get the sandbox working, let's check to see if the `/proc` node created by the aforementioned patch is present and configured in a way that will cause us problems. If so, give the user a suggestion for how to troubleshoot the problem.	2022-07-17 01:27:22 -07:00
Adam Joseph	6fc56318bf	local-derivation-goal.cc: add comment re: CLONE_NEWUSER ... local-derivation-goal.cc contains a comment stating that "Some distros patch Linux to not allow unprivileged user namespaces."
