Increase schedulingPriority of the bootstrap tools to unblock the
nixpkgs-unstable channel.
The channel is repeatedly blocked by the makeBootstrapTools job for
aarch64. The cause is lack of resources.
By increasing the priority, it should become the first job Hydra would
build, allowing the channel to advance quicker. Of course, it does mean
that while the channel advances, nothing else has been built.
This should be a temporary solution until we have more capacity for
aarch64.
The dynamic loader on powerpc64 is called ld64.so.2 rather than
ld-linux.so.*, and was not matched by the existing pattern.
We reuse the dynamicLinker name from binutils to match a wider set
of platforms and to avoid specifying this information in two places.
These files never existed, so best to not leave the reference. If
someone want to step up to maintain this, that would be fine. I don’t
have the hardware to test these out. In addition, someone tried to use
the bootstrap-tools currently built by Hydra and found that they were
broken in some unclear way.
The linker scripts no longer contain store paths, so this does nothing. More
importantly, libpthread.so is not longer a linker script on ARM, so the patching
would corrupt it.
There's a generated header that got comment about the source header
from glibc.dev, which added unwanted runtime dependency. Tested:
nix build -f pkgs/top-level/release.nix stdenvBootstrapTools.{aarch64,i686,x86_64}-linux.test
Apparently this option trades compression time for size,
and explicitly does so without increasing resources needed in decomp.
Doesn't make tarball creation unbearable, so add it to options!
crossOverlays only apply to the packages being built, not the build
packages. It is useful when you don’t care what is used to build your
packages, just what is being built. The idea relies heavily on the
cross compiling infrastructure. Using this implies that we need to
create a cross stdenv.
This allows cross builds to work. Evidentallyy this has been done wrong
since I combined the bootstrap tool creation files in
ab651d2c9bab620ebe5e515476fbd70d2c5b0c61. Oops!
Since gcc.lib/lib64 is a symlink to 'lib', the use of
"lib*/libgcc_s.so*" triggered a warning (error) with
the latest coreutils. Essentially we were doing:
$ cp a/x b/x y/
And latest coreutils rejects such invocations.
Just copy from 'lib', lib64 is a link to it anyway.
* Nothing else in this file bothers looking at lib*
* AFAICT lib* only ever possibly matched lib64 anyway
02c09e01712ce0b61e5c8f7159047699a434f7fc (NixOS/nixpkgs#44558) was reverted in
c981787db951afb11c1328461df82d4277ebec07 but, as it turns out, it fixed an issue
I didn't know about at the time: the values of `propagateDoc` options were
(and now again are) inconsistent with the underlying things those wrappers wrap
(see NixOS/nixpkgs#46119), which was (and now is) likely to produce more instances
of NixOS/nixpkgs#43547, if not now, then eventually as stdenv changes.
This patch (which is a simplified version of the original reverted patch) is the
simplest solution to this whole thing: it forces wrappers to directly inspect the
outputs of the things they are wrapping instead of making stdenv guess the correct
values.
This reverts commit a809fdc8e1b0c1d49d40815d9bac0de27ddab5f1 and then
achieves the same result (not rebuilding texinfo three times)
but without dragging bootstrap tools into the closure.
