This commit adds test based on real-world crates (brotli).
There were a few more edge cases that were missing beforehand. Also it
turned out that we can get rid of the `finalBins` list since that will
now be handled during runtime.
The build expression got quiet large over time and to make it a bit
easier to grasp the different scripts involved in the build are now
separated from the nix file.
Cargo has a few odd (old) ways of picking source files if the `bin.path`
attribute isn't given in the Cargo.toml. This commit adds support for
some of those. The previous behaviour always defaulted to `src/main.rs`
which was not always the right choice.
Since there is look-ahead into the unpacked sources before running the
actual builder the path selection logic has to be embedded within the
build script.
`buildRustCrate` currently supports two ways of running building
binaries when processing a crate:
- Explicit definition of all the binaries (& optionally the paths to
their respective `main.rs`) and,
- if not binary was explictly configured all files matching the patterns
`src/main.rs`, `src/bin/*.rs`.
When the explicit list is given without path information paths are now
being picked from a list of candidates. The first match wins. The order
is the same as within the cargo compatibility code.
If the crate does not provide any libraries the path `src/{bin_name}.rs`
is also considered.
All underscores within the binary names are translated into dashes (`-`)
before the lookups are made. This seems to be a common convention.
Previously the Release.xz URL would show up with a new hash whenever
debian releases an update. By using archive.org we should have a stable
source for those. I wasn't able to find the equivalent in the debian
world. Maybe they don't keep all the different Release files around..
By setting useRealVendorConfig explicitly to true, the actual (slightly
modified) config generated by cargo-vendor is used.
This solves a problem, where the static vendor config in
pkgs/build-support/rust/default.nix would not sufficiently replace all
crates Cargo is looking for.
As useRealVendorConfig (and writeVendorConfig in fetchcargo) default to
false, there should be no breakage in existing cargoSha256 hashes.
Nethertheless, imho using this new feature should become standard. A
possible deprecation path could be:
- introduce this patch
- set useRealVendorConfig explicitly to false whereever cargoSha256 is
set but migration is not wanted yet.
- after some time, let writeVendorConfig default to true
- when useRealVendorConfig is true everywhere cargoSha256 is set and
enough time is passed, `assert cargoVendorDir == null ->
useRealVendorConfig;`, remove old behaviour
- after some time, remove all appearences of useRealVendorConfig and the
parameter itself
Introduce a `skawarePackages.buildPackage` function that contains the
common setup, removing a lot of duplication.
In particular, we require that the build directory has to be empty
after the `fixupPhase`, to make sure every relevant file is moved to
the outputs.
A next step would be to deduplicate the `configureFlags` attributes
and only require a `skawareInputs` field.
There's no reason `linkFarm` can't be used for symlinks in
subdirectories, except that currently it doesn't ensure the directory
of the link exists. This backwards-compatible change expands the utility
of the function.
This hopefully makes patchShebangs respect cross compilation. It
introduces the concept of the HOST_PATH. Nothing is ever executed on
it but instead used as a way to get the proper path using ‘command
-v’. Needs more testing.

even corrupt binaries :(.
When we run patchelf it masks the problem
by removing obviously busted paths.
Which is probably why this wasn't noticed immediately.
Unfortunately the binary already
has a long series of paths scribbled
in a space intended for a much smaller string;
in my testing it was something like
lengths were 67 with 300+ written to it.
I think we've reported the relevant issues upstream,
but unfortunately it appears our patches
are what introduces the overwrite/corruption
(by no longer being correct in what they assume)
This doesn't look so bad to fix but it's
not something I can spend more time on
at the moment.
--
Interestingly the overwritten string data
(because it is scribbled past the bounds)
remains in the binary and is why we're suddenly
seeing unexpected references in various builds
-- notably this is is the reason we're
seeing the "extra-utils" breakage
that entirely crippled NixOS on master
(and probably on staging before?).

With the recent update of BusyBox to version 1.29.0 in
d6aa506e3b there is now a new dependency
on libresolv.
This now throws a runtime error when executing ash, eg. whenever we do
something like this:
nix-build -E 'with import ./. {}; vmTools.runInLinuxVM hello'
The resulting error will be:
.../ash: error while loading shared libraries: libresolv.so.2: cannot
open shared object file: No such file or directory
I tried to override BusyBox with enableStatic, but that still requires
parts of glibc:
Static linking against glibc, can't use --gc-sections
Trying libraries: crypt m resolv
Library crypt is not needed, excluding it
Library m is needed, can't exclude it (yet)
Library resolv is needed, can't exclude it (yet)
Library m is needed, can't exclude it (yet)
Library resolv is needed, can't exclude it (yet)
Final link with: m resolv
In the long term maybe switching to a more minimal C library such as
musl would make more sense, but for now I just added libresolv.so to the
initrd which fixes the runtime error.

All package sets are simultaneously updated to accommodate changes to
package-build. Due to new restrictions in package-build, all packages using
`melpaBuild` must now provide a recipe file, even those packages which are not
included in upstream MELPA.
So far the runtimeDependencies variable has been rather useless unless
you also set dontPatchelf, because the patchelf setup hook ran *after*
the autoPatchelfHook and thus stripped off the additional RPATHs added
using runtimeDependencies.
I did this by moving the autoPatchelfHook to be run in postFixup instead
of fixupOutput, however I needed to replicate the for loop that runs the
hook on all outputs.
Until we have a way to influence order of execution for hooks I've
marked this with an XXX so that we can use fixupOutput again.
Tested this against all packages that use autoPatchelfHook using the
following and checking whether the output contains any errors concerning
shared libraries:
nix-build -E 'with import ./. { config.allowUnfree = true; };

This might also happen when pulling a patch from GitHub or a similar web
interface without explicitly selecting the "raw" format.
Excludes and includes are implemented by passing the parameters to the
respective flags of `filterdiff`. Those were passed unescaped until now.
Since those flags expect patterns (similar to shell globs), something
like `/some/path/*` might be used to exclude or include all files in
some path. Without escaping the shell would expand the `*`, leading to
unexpected behaviour.
This commit was originally introduced as part of #41420 and then

docker-tools tests load images without specifying any tag
value. Docker then uses the image with tag "latest" which doesn't
exist anymore since commit 39e678e24e.
In particular, this contains Firefox-related and libgcrypt updates.
Other larger rebuilds would apparently need lots of time to catch up
on Hydra, due to nontrivial rebuilds in other branches than staging.
A .la file specifies linker flags to link with the library it describes. Its
"dependency_libs" field lists the libraries that this library depends upon.
This list often contains "-l" flags without corresponding "-L" flags. Many
packages in Nixpkgs deal with this in one of these ways:
- delete .la file [1]
- clear dependency_libs [2]
- add -L flags to dependency_libs [3]
- propagate dependencies [4]
Sometimes "dependency_libs" contain wrong "-L" flags pointing to the "dev"
output with headers rather than to the main output with libraries. They have to
be edited or deleted to reduce closure size [5].
Deleting .la files is often but not always safe [6]. Atomatically deleting as
many of them as possible is complex [7]. Deleting .la files that describe
shared rather than static libraries is probably safe; but clearing their
"dependency_libs" field achieves the same effect with less potential for
unintended consequences. This is the approach that may be enabled for all
Nixpkgs.

If there is a shared object or executable that's using

"application/x-pie-executable", so until this change its dependencies

Attributes `imageName` and `imageTag` are exposed if the image is
built by our Nix tools but not if the image is pulled. So, we expose
these attributes for convenience and homogeneity.
Skopeo used by our docker tools was patched to work in the build
sandbox (it used /var/tmp which is not available in the sandbox).
Since this temporary directory can now be set at build time, we remove
the patch from our docker tools.
The extraCommands was, previously, simply put in the body of the script
using nix expansion `${extraCommands}` (which looks exactly like bash
expansion!).
This causes issues like in #34779 where scripts will eventually create
invalid bash.
The solution is to use a script like `run-as-root`.

toPath has confusing semantics and is never necessary; it can always
either just be omitted or replaced by pre-concatenating `/.`. It has
been marked as "!!! obsolete?" for more than 10 years in a C++
comment, hopefully removing it will let us properly deprecate and,
eventually, remove it.
The hack of using `crossConfig` to enforce stricter handling of
dependencies is replaced with a dedicated `strictDeps` for that purpose.
(Experience has shown that my punning was a terrible idea that made more
difficult and embarrising to teach teach.)
Now that is is clear, a few packages now use `strictDeps`, to fix
various bugs:
- bintools-wrapper and cc-wrapper
Regression introduced in 736848723e.
This commit most certainly hasn't been tested with sandboxing enabled
and breaks not only pullImage but also the docker-tools NixOS VM test
because it doesn't find it's certificate path and also relies on
/var/tmp being there.
Fixing the certificate path is the easiest one because it can be done
via environment variable.
I've used overrideAttrs for changing the hardcoded path to /tmp (which
is available in sandboxed builds and even hardcoded in Nix), so that
whenever someone uses Skopeo from all-packages.nix the path is still
/var/tmp.
The reason why this is hardcoded to /var/tmp can be seen in a comment in
vendor/github.com/containers/image/storage/storage_image.go:
Do not use the system default of os.TempDir(), usually /tmp, because
with systemd it could be a tmpfs.
With sandboxed builds this isn't the case, however for using Nix without
NixOS this could turn into a problem if this indeed is the case.
So in the long term this needs to have a proper solution.
In addition to that, I cleaned up the expression a bit.
Tested by building dockerTools.examples.nixFromDockerHub and the
docker-tools NixOS VM test.

Skopeo is used to pull images from a Docker registry (instead of a
Docker deamon in a VM).
An image reference is specified with its name and its digest which is
an immutable image identifier (unlike image name and tag).
Skopeo can be used to get the digest of an image, for instance:
$ skopeo inspect docker://docker.io/nixos/nix:1.11 | jq -r '.Digest'
... binutils and gcc add it already anyway.
Without this it's easy to get cross-toolchain paths longer than 256
chars and nix-daemon will then fail to commit them to /nix/store on XFS.
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

Since the script running is a failure condition, we should fail the
build properly, not leaving it up to the missing output to determine
that the build went wrong. This should partly address #38952 — nix
build will print out the build log on non-zero exits.
Also fix numberous bugs, such as:
- Not getting confused on more flags taking file arguments.
- Ensuring children reexport their children, but the original
binary/library doesn't.
- Not spawning children when it turns out we just dynamically link
under the threshold but our total number of inputs exceeeds it.
- Children were always named `libunnamed-*`, when that name was
supposed to be the last resort only.
ld-wrapper's own RPATH check hardcodes `.so`, but darwin uses `.dylib`

however because we never inject `--rpath` like that in practice on

Pull request #38470 added support for running/building kernels without

unfortunately while this works perfectly on kernels without modules it
also makes sure that *every* kernel gets no modules.

Setting the hash to null is a convenient way to bypass the hash check
while developing. It looks like the ability to do this was inadvertently
removed while adding vendor directory support.
This still checks that the user is explicitly setting the value but
allows null as a valid option.
This is to go to a reproducible image build.
Note without this options image are identical from the Docker point of
view but generated docker archives could have different hashes.
This is to improve image creation reproducibility. Since the nar
format doesn't support hard link, the tar stream of a layer can be
different if a dependency of a layer has been built locally or if it
has been fetched from a binary cache.
If the dependency has been build locally, it can contain hard links
which are encoded in the tar stream. If the dependency has been
fetched from a binary cache, the tar stream doesn't contain any hard
link. So even if the content is the same, tar streams are different.

Existing "mips64el" should be "mipsel".
This is just the barest minimum so that nixpkgs can recognize them as

MIPS boards, it is not sufficient if you want to actually build nixos on
those targets
Previously, cargoUpdateHook was meaningful as it was used
in
[`cargo-fetch-deps`](19d3cf81d3/pkgs/build-support/rust/fetch-cargo-deps (L71)).
However, this entire file was removed in
5f8cf0048e. As far as I can
tell, nothing in the code is using it, but it is still
being passed around:
https://github.com/NixOS/nixpkgs/search?q=cargoUpdateHook&type=Code&utf8=%E2%9C%93
There are, however, legitimate use cases for it. For example,
in some software, some dependencies are not locked in Cargo.toml
and this causes Cargo to try fetching another version of them.
This doesn't work well with vendoring crates.
This hook allows to inject patching or whatever necessary workarounds
in the crate vendoring process. I suppose that's what it was for
in there in the first place.
This patch restores this hook and makes it usable again.
Before the code would fail silently for zero values and with some output for
empties. We now currently handle both via defaulting value to zero and making
`let` return success error code when there's no syntax error.
A separate function for building Bazel-bazed packages. Internally it splits the
build into two phases, fetching and building.
Users are expected to provide `fetchArgs.sha256` -- checksum of fetched
dependencies. Local dependencies should be removed in `fetchArgs.preInstall`.
Overall `fetchArgs` and `buildArgs` can be used to add specific steps to fetch
and build.
`find -executable` finds everything with the executable bit set,
including directories. Thats not harmful in this scenario as `cp` won't
copy those directories, but it does result in a few warning messages.
I originally wrote this for packaging proprietary games in Vuizvui[1]
but I thought it would be generally useful as we have a fair amount of
proprietary software lurking around in nixpkgs, which are a bit tedious
to maintain, especially when the library dependencies change after an
update.
So this setup hook searches for all ELF executables and libraries in the
resulting output paths after install phase and uses patchelf to set the
RPATH and interpreter according to what dependencies are available
inside the builder.
For example consider something like this:
stdenv.mkDerivation {
...
nativeBuildInputs = [ autoPatchelfHook ];
buildInputs = [ mesa zlib ];
...
}
Whenever for example an executable requires mesa or zlib, the RPATH will
automatically be set to the lib dir of the corresponding dependency.
If the library dependency is required at runtime, an attribute called
runtimeDependencies can be used to list dependencies that are added to
all executables that are discovered unconditionally.
Beside this, it also makes initial packaging of proprietary software
easier, because one no longer has to manually figure out the
dependencies in the first place.

Among other things, this will allow *2nix tools to output plain data
while still being composable with the traditional
callPackage/.override interfaces.
Summary:
According to git-submodule manpage,
"git submodule status" prefixes the hash with a '-' if it is not
initialized, and other chars in other circumstances.
(this is consistent on the various git versions tested)
nix-prefetch-git runs "git submodule init" which does you'd think,
but apparently despite this earlier versions of git before 2.16
would still give the hash the '-' suffix.
In particular this is the behavior when using 2.15 and 2.14.1
from the nixos-17.09 and nixos-17.03 channels respectively.
The script then used awk to drop the first char of the first field
which does the wrong thing when there is no prefix emitted:
while there is a space character before the hash, this is not
part of the field and so we ended up eating the first character
of the hash.
To fix this in a way that also works with the previous behavior,
this commit instead uses awk to grab the hash field
and uses tr to delete any '-' chars should they be present.
This seems to work in my testing, and for example can now
successfully fetch the source for "nginxModules.brotli"
where previously it would generate an error:
fatal: '22564a95d9ab58865a096b8d9f7324ea5f2e03e' is not a commit and a branch 'fetchgit' cannot be created from it
(we dropped a '2' from the beginning of the hash)
