* 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.
Running the following expression with nix-shell:
let
pkgs = import <nixpkgs> {};
shell1 = pkgs.mkShell {
shellHook = ''
echo shell1
'';
};
shell2 = pkgs.mkShell {
shellHook = ''
echo shell2
'';
};
shell3 = pkgs.mkShell {
inputsFrom = [ shell1 shell2 ];
shellHook = ''
echo shell3
'';
};
in shell3
Will now results in:
shell2
shell1
shell3
Note that packages in the front of inputsFrom have precedence over
packages in the back. The outermost mkShell has precedence over all.
The previous behaviour would work fine as long as `symlink` is a link to
a file. If is a link to a directory though, the new `ln` wouldn't
overwrite it but would create a new link *in that directory* (with the
name of the link source).
Instead, we can precompute the target location, then first remove the
symlink and write the new one in its place.
After bumping sublime3 in #61636 we realized that saving files as root
doesn’t work anymore and somehow the paths weren’t patched by
`libredirect`.
After some debugging it came out that Sublime switched from `posix_spawn(3)`
to `posix_spawnp(3)` to start new processes internally. Since `libredirect`
only handled the former, `/usr/bin/pkexec` stopped being redirected.
Wrapping `posix_spawnp` fixes the problem.
PR #58431 added /nix/store to each layer.tar. However, the timestamp was
not explicitly set while adding /nix and /nix/store to the archive. This
resulted in different SHA256 hashes of layer.tar between image builds.
This change sets time and owner when tar'ing /nix/store.
To avoid symlink loops to /host in nested chrootenvs we need to remove
one level of indirection. This is also what's generally expected of
/host contents.
* Remove unused argument from pivot_root;
* Factor out tmpdir creation into a separate function;
* Remove unused fstype from bind mount;
* Use unlink instead of a treewalk to remove empty temporary directory.
The problem with stacking chrootenv before was that CLONE_NEWUSER cannot
be used when a child uses chroot. So instead of that we use pivot_root
which replaces root in the whole namespace. This requires our new root
to be an actual fs so we mount tmpfs.
not all valid file names are valid derivation names. This can cause
troubles when, for example, trying to place systemd template unit
files, which contain an '@' in their name, in an initrd.
Fixes#53987
glibc 2.27 (and possibly other versions) can't handle an `nopenfd` value larger than 2^19 in `ntfw`, which is problematic if you've set the maximum number of fds per process to a value higher than that.
Commit "patchShebangs: Allow for multiple arguments" 4a1e51f957
removed the check. We don't want to break existing usages so this
introduces it again with a successful exit code.
It's tempting to think patchShebangs supports multiple arguments.
Without this patch it just silently ignores all but the first. Now it
patches the shebangs in all of its arguments.
Fixes: #57695
This hook allows to add NixOS driver libraries path to given ELF
objects' RUNPATH. We use it instead of settings RUNPATH manually
everywhere. It must be invoked in postFixup so that RUNPATH stripping
does not remove the path.
It puts the path first instead of last so that system-wide drivers
are always preferred.
The layer order was not correct when a parent image was used: parent
image layers were above the new created layer.
This commits simplifies the code related to layer ordering. In
particular, layers in `layer-list` are ordered from bottom-most to
top-most. This is also the order of layers in the `rootfs.diff_ids`
attribute of the image configuration.
