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.

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.
While it might be useful in some cases, there are too many caveats to be worth it.
When libredirect intercepts dlopen call and calls the original function, the dynamic
loader will use libredirect.so's DT_RUNPATH entry instead of the one from the ELF file
the dlopen call originated from. That means that when program tries to dlopen a library
that it expects to find on its RPATH, the call will fail.
This broke Sublime Text for just that reason.
Especially as a new user it is a much better experience to receive a
proper help response to `-h`. Currently passing `-h` will cause some
runtime error with the `git remote` error help being shown. Not very
helpful.
It doesn't hurt to be a bit more user friendly in this case.
This introduces extra escaping for $NIX_STORE that gets interpolated
into a PCRE. The escaping is performed using a standard Perl function
"quotemeta" (see "perldoc -f quotemeta" for reference). The same value
is also used in sed regex which uses POSIX basic regular expressions
instead of PCRE, so it needs fewer characters to be escaped. It should
not cause much problem to not change sed invocation, but I replace it
with equivalent Perl expression (actually the behavior is changed to not
output a newline character after the matched output).
We want to make sure this value is explicitly set. Infering it for
every arch leads to annoying failures like:
https://hydra.nixos.org/build/92583832/
Perhaps we can enable it in the future with some smarter handling of
cc-wrapper.sh.
Creating the timestamp in the patched script's directory has a few
drawbacks:
* if "foo.timestamp" already exists, it will be overwritten
* it requires the directory to be writable
Adds pkgsCross.wasm32 and pkgsCross.wasm64. Use it to build Nixpkgs
with a WebAssembly toolchain.
stdenv/cross: use static overlay on isWasm
isWasm doesn’t make sense dynamically linked.
