This removes the unnecessary compiler build dependency. We also set
preferLocalBuild = true;
allowSubstitutes = false;
to not farm out the build on a remote builder or bother with trying to
find a binary substitution.
The architecture of an image should default to the architecture for
which that image is being composed or pulled. buildPackages.go.GOARCH is
an easy way to compute that architecture with the correct terminology.
These should not cause issues in practice but it is good idea to handle them.
* prefix and targetOffset are mandatory, as they are always set by the generic builder.
* wrapPrefixVariables and dontWrapGApps are now defaulting to empty value, as they are not mandatory.
Before this change, buildRustCrate always called rustc with
--extern libName=[...]libName[...]
However, Cargo permits using a different name under which a dependency
is known to a crate. For example, rand 0.7.0 uses:
[dependencies]
getrandom_package = { version = "0.1.1", package = "getrandom", optional = true }
Which introduces the getrandom dependency such that it is known as
getrandom_package to the rand crate. In this case, the correct extern
flag is of the form
--extern getrandom_package=[...]getrandom[...]
which is currently not supported. In order to support such cases, this
change introduces a crateRenames argument to buildRustCrate. This
argument is an attribute set of dependencies that should be renamed. In
this case, crateRenames would be:
{
"getrandom" = "getrandom_package";
}
The extern options are then built such that if the libName occurs as
an attribute in this set, it value will be used as the local
name. Otherwise libName will be used as before.
luarocks defines by default the following mirrors:
83093e7da7/src/luarocks/core/cfg.lua (L205)
Let's add them to nixpkgs. I have modified luarocks-nix to generate the
proper nixpkgs urls.
I bump luarocks-nix in the following commits.
This is a new package that provides a shell hook to make it easy to
declare manpages and shell completions in a manner that doesn't require
remembering where to actually install them. Basic usage looks like
{ stdenv, installShellFiles, ... }:
stdenv.mkDerivation {
# ...
nativeBuildInputs = [ installShellFiles ];
postInstall = ''
installManPage doc/foobar.1
installShellCompletion --bash share/completions/foobar.bash
installShellCompletion --fish share/completions/foobar.fish
installShellCompletion --zsh share/completions/_foobar
'';
# ...
}
See source comments for more details on the functions.
applyPatches applies a list of patches to a source directory.
For example to patch nixpkgs you can use:
applyPatches {
src = pkgs.path;
patches = [
(pkgs.fetchpatch {
url = "1f770d2055.patch";
sha256 = "1nlzx171y3r3jbk0qhvnl711kmdk57jlq4na8f8bs8wz2pbffymr";
})
];
}
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.
Hydra nixpkgs: ?compare=1538299
They always can be regenerated during the actual build, and they are sometimes
random, e.g in Tensorflow;
platforms -> NIX_BUILD_TOP/tmp/install/35282f5123611afa742331368e9ae529/_embedded_binaries/platforms
This setup hook modifies a Perl script so that any "-I" flags in its shebang
line are rewritten into a "use lib ..." statement on the next line. This gets
around a limitation in Darwin, which will not properly handle a script whose
shebang line exceeds 511 characters.
Turns out markers are non-deterministic after all and even our patching still
doesn't solve this problem completely. For example (tensorflow deps, this is a
complete diff so actual dependencies don't differ):

Instead of trying to patch these markers further we now completely clear them.
Nix hacks for ignoring markers are restored and expanded so that we don't even
attempt to parse the marker.
* buildBazelPackage: autodetect nix toolchain instead of Xcode on Darwin
* do not export the variables outside of Darwin
* remove unecessary parens
* move comment within the darwin check
Timestamp verification skip is no longer needed (not sure why). Generally we
better off always using the environment hack for all packages because that
ensures all NIX_* flags are correctly applied.
One possible improvement in future is to filter only NIX_* variables to
passthru in Bazel.
Before one would get the following error
nix-repl> pkgs.writeTextDir "share/my-file" "foo"
error: invalid character '/' in name 'share/my-file'
Fixes #50347
Previously the installPhase of the fixed ouput derivation would fail for
a package that has no markers, since `sed` would complain about having
no input files. If we use `find` instead of bash globs, that problem
goes away.
This avoids dumping -Wall warnings when they appear in framework
headers. As a result, we are closer to how regular headers are
included (via -isystem).
Also remove ccIncludeFlag lookup, this was unused & not very useful.
mergeInputs is now simply defined in terms of `concatLists` and
`catAttrs` instead of a more complicated `foldr`.
Note that the order of PATH has also changed. For example running the
following with nix-shell:
let
pkgs = import <nixpkgs> {};
shell1 = pkgs.mkShell {
buildInputs = [ pkgs.htop ];
};
shell2 = pkgs.mkShell {
buildInputs = [ pkgs.hello ];
};
shell3 = pkgs.mkShell {
inputsFrom = [ shell1 shell2 ];
buildInputs = [ pkgs.tree ];
};
in shell3
Results in the following PATH:
$ echo $PATH
...
/nix/store/yifq4bikf7m07160bpia7z48ciqddbfi-tree-1.8.0/bin:
/nix/store/vhxqk81234ivqw1a7j200a1c69k8mywi-htop-2.2.0/bin:
/nix/store/n9vm3m58y1n3rg3mlll17wanc9hln58k-hello-2.10/bin
...
Previously the order was:
/nix/store/n9vm3m58y1n3rg3mlll17wanc9hln58k-hello-2.10/bin
/nix/store/vhxqk81234ivqw1a7j200a1c69k8mywi-htop-2.2.0/bin:
/nix/store/yifq4bikf7m07160bpia7z48ciqddbfi-tree-1.8.0/bin:
I think the new order makes more sense because it allows to override
the PATH in the outermost mkShell.
