buildRustCrate has a handy `include` helper, that only imports those whitelisted
files and folders to the store.
However, the function's matching logic is broken and includes all files,
regardless of whether or not they're whitelisted, as long as the whitelist
contains at least one name (regardless of whether that name exists). This is
because it doesn't take into account that
`lib.strings.removePrefix "foo" "bar" == "bar"` (that is, paths that don't match
the prefix are passed straight through).
This rare sitation was caught when building zoom-us package:
```

```
The worst is that derivation continued and resulted into broken package:
https://github.com/NixOS/nixpkgs/pull/55566#issuecomment-470065690
I hope, replacing `grep -q` with `grep` will remove this race condition.
When a package provides both executables and gio modules, it is quite
probable the executables will need those modules. wrapGAppsHook wraps
executables with GIO_EXTRA_MODULES picked up from dependencies
but forgets about the package being built. Let’s add to consideration.
Closes: https://github.com/NixOS/nixpkgs/issues/50254
On very large graphs (14k+ paths), we'd end up with a massive in
memory tree of mostly duplication.
We can safely cache trees and point back to them later, saving
memory.
While it is not obvious from the source, cargo sets CARGO_MANIFEST_DIR to an absolute directory. This let to a build problem with the popular "tera" crate using the "pest" crate.
## Cargo details
The variable is set here:
f7c91ba622/src/cargo/core/compiler/compilation.rs (L229)
and computed from the `manifest_path`:
f7c91ba622/src/cargo/core/package.rs (L163)
The manifest path is also exported via `cargo metadata` where you can see that it is absolute.
Whenever we create scripts that are installed to $out, we must use runtimeShell
in order to get the shell that can be executed on the machine we create the
package for. This is relevant for cross-compiling. The only use case for
stdenv.shell are scripts that are executed as part of the build system.
Usages in checkPhase are borderline however to decrease the likelyhood
of people copying the wrong examples, I decided to use runtimeShell as well.
The execlineb program is the launcher (and lexer) of execline scripts.
So it makes a lot of sense to have all the small tools in scope by
default.
We append to the end of PATH so that they can be easily overwritten by
the user.

The appimageTools attrset contains utilities to prevent
the usage of appimage-run to package AppImages, like done/attempted
in #49370 and #53156.
This has the advantage of allowing for per-package environment changes,
and extracts into the store instead of the users home directory.
The package list was extracted into appimageTools to prevent
duplication.
bcf54ce5bb introduced a treewide change to
use ${stdenv.shell} where-ever possible. However, this broke a script
used by dockerTools, store-path-to-layer.sh, as it did not preserve the
+x mode bit. This meant the file got put into the store as mode 0444,
resulting in a build-time error later on that looked like:
xargs: /nix/store/jixivxhh3c8sncp9xlkc4ls3y5f2mmxh-store-path-to-layer.sh: Permission denied
However, in a twist of fate, bcf54ce5bb
not only introduced this regression but, in this particular instance,
didn't even fix the original bug: the store-path-to-layer.sh script
*still* uses /bin/sh as its shebang line, rather than an absolute path
to stdenv. (Fixing this can be done in a separate commit.)

The original change in #55372 was supposed to fix the case where a store
path which is a file should be placed into `buildEnv` which broke with a
fairly misleading Perl error.
Unfortunately this introduced a regression, `findFiles` can have targets
that are files if the file isn't a store path. Rather than adding more
obscure checks with probably further regressions, I figured that it's
better to replicate the behavior of `lib.isStorePath` and explicitly
check if the store path is a file and break in this case only.
This should also fix recent staging issues.
I noticed by creating `buildEnv` where I accidentally put a derivation
from `pkgs.writeText` into `paths` and got a broken build with the
following misleading error message:
```
Use of uninitialized value $stat1 in numeric ne (!=) at /nix/store/9g4wc31j7a2xp22xpgwr0qssfxahxdzl-builder.pl line 74.
Use of uninitialized value $stat1 in bitwise and (&) at /nix/store/9g4wc31j7a2xp22xpgwr0qssfxahxdzl-builder.pl line 75.

```
It can be reproduced with an expression like this:
``` nix
{ pkgs ? import <nixpkgs> { } }:
let
file = pkgs.writeText "test" ''
content
'';
in
pkgs.buildEnv {
name = "test-env";
paths = [ /* ... */ file ];
}
```
In combination with carnix we can now build crates that require a
specific edition of rust features. A few crates started requiring that
already and having this in nixpkgs is just logical.
This patch preserves the ordering of layers of a parent image when the
new image is packed.
It is currently not the case: layers are stacked in the reverse order.

This round is without the systemd CVE,
as we don't have binaries for that yet.
BTW, I just ignore darwin binaries these days,
as I'd have to wait for weeks for them.
Emacs loads all the elisp files in the top-level of the site-lisp
directory. However some packages (e.g. mu4e) put their elisp files in a
subdirectory of site-lisp. Emacs will not load these packages unless
subdirs.el is present.
This commit links the subdirs.el file from the emacs package into the
emacs-package-deps package so that packages that put their elisp files
in a subdirectory of site-lisp are loaded.
Comments on conflicts:
- llvm: d6f401e1 vs. 469ecc70 - docs for 6 and 7 say the default is
to build all targets, so we should be fine
- some pypi hashes: they were equivalent, just base16 vs. base32
Unless dontWrapGapps is set, the wrap-gapps-hook.sh will currently
wrap all executables (and symbolic links to executables) found under
the target directories: bin and libexec.
As a result, if a symbolic link in a target directory points to an
executable in a target directory, both will get wrapped. This
causes an extra shell/exec when following the symbolic link,
as well as increasing the size of the final executable's environment.
To avoid wrapping a link to an already wrapped executable, this
commit splits the determination of what gets wrapped into two phases:
1. All binaries under the target directories are wrapped and logged
with "Wrapping program ..."
2. All links to executables under the target directories are
identified and checked to see if they reference an executable
under one of the target directories.
If yes, the required wrapping has already been performed on
the associated binary (in phase 1), so no wrapping is done
and "Not wrapping link: ... (already wrapped)" is logged.
If no, the link points at an executable that hasn't been
wrapped, so the link is wrapped and "Wrapping link: ..." is logged.
As an example, the yelp package has a bin directory that contains
an executable "yelp" and a symbolic link "gnome-help" -> "yelp".
Prior to this commit, the bin directory would contain these files
after wrapping:
gnome-help -- wrapper to exec .gnome-help-wrapped
.gnome-help-wrapped -- a symbolic link to yelp
yelp -- wrapper to exec .yelp-wrapped
.yelp-wrapped -- the original yelp binary
After this commit, the bin directory will instead contain:
gnome-help -- a symbolic link to yelp
yelp -- wrapper to exec .yelp-wrapped
.yelp-wrapped -- the original yelp binary
NOTE: The primary motivation for this commit is to avoid obscuring
the fact that two or more paths are simple aliases and expected to
behave identically. It also reduces the likelihood of hitting
limits related to environment variable size.
LIMITATION: The method used above is intended to be conservative
and will still wrap symbolic links to other symbolic links when
the ultimate target is outside of bin or libexec.
There is a function params `kernel' intended to specify which kernel to use.
It defaults to `pkgs.linux`.
But when we override `kernel', compiling and using two kernels seems not to be the intendend bevavior.
clang needs to find headers + libraries for compiling with libc++. We
need to add a libcxx argument to cc-wrapper. This means you do not
have to pass in c++ headers directly.
This resolves the last case remaining of #30670. Darwin clang++ now
works properly.
Fixes#30670
This is useful when running tools like NixOps or nix-review
on workstations where the upload to the builder is significantly
slower then downloading the source on the builder itself.
* add generic x86_32 support
- Add support for i386-i586.
- Add `isx86_32` predicate that can replace most uses of `isi686`.
- `isi686` is reinterpreted to mean "exactly i686 arch, and not say i585 or i386".
- This branch was used to build working i586 kernel running on i586 hardware.
* revert `isi[345]86`, remove dead code
- Remove changes to dead code in `doubles.nix` and `for-meta.nix`.
- Remove `isi[345]86` predicates since other cpu families don't have specific model predicates.
* remove i386-linux since linux not supported on that cpu
* fetchurl: fix and add extra KDE mirrors (#51480)
- The gwdg.de mirror has moved the relative path of its KDE tarballs
- Add new mirrors from Berkeley and MIT, which are on the list of officially supported mirrors
https://download.kde.org/extra/download-mirrors.html
* More KDE mirror touchups
- The official one is a redirect to HTTPS anyways, so go directly to HTTPS
- Add China USTC for Asian users
- Swap Finland university from FTP to HTTP
* fetchurl: keep one ftp KDE mirror
Docker images used to be, essentially, a linked list of layers. Each
layer would have a tarball and a json document pointing to its parent,
and the image pointed to the top layer:
imageA ----> layerA
|
v
layerB
|
v
layerC
The current image spec changed this format to where the Image defined
the order and set of layers:
imageA ---> layerA
|--> layerB
`--> layerC
For backwards compatibility, docker produces images which follow both
specs: layers point to parents, and images also point to the entire
list:
imageA ---> layerA
| |
| v
|--> layerB
| |
| v
`--> layerC
This is nice for tooling which supported the older version and never
updated to support the newer format.
Our `buildImage` code only supported the old version, so in order for
`buildImage` to properly generate an image based on another image
with `fromImage`, the parent image's layers must fully support the old
mechanism.
This is not a problem in general, but is a problem with
`buildLayeredImage`.
`buildLayeredImage` creates images with newer image spec, because
individual store paths don't have a guaranteed parent layer. Including
a specific parent ID in the layer's json makes the output less likely
to cache hit when published or pulled.
This means until now, `buildLayeredImage` could not be the input to
`buildImage`.
The changes in this PR change `buildImage` to only use the layer's
manifest when locating parent IDs. This does break buildImage on
extremely old Docker images, though I do wonder how many of these
exist.
This work has been sponsored by Target.
This ensures that RPATH entries like "/foo/build/bar" doesn't trigger a
match when TMPDIR is "/build/bar". (I've had this problem with a
prebuilt package.)
If there was no older file than $NIX_BUILD_TOP this would result in a
warning, e.g. with nix-info.

This commit causes melpaBuild to use package-build from melpa/package-build
instead of melpa/melpa. Development of package-build happens in the former
repository whereas the latter is much larger, containing also the MELPA
recipes. We do not need to fetch the MELPA recipes from melpa/melpa, as we fetch
them one-by-one for Nixpkgs.
No real function change here, but this updates the trivial and melpa builders to
be formatted more consistently with the rest of the builders, and swaps
`eval "$preBuild"` for the more standard `runHook preBuild`.
If the file in question is not a shared object file but an ELF, we
really want to skip the file, because we won't have anything to patch
there.
For example if the file is created via "gcc -c -o foo.o foo.c", we don't
get a segment header and so far autoPatchelf was trying to patch such a
file.
By checking for missing segment headers, we're now no longer going to
attempt patching such a file.

This function is useful if autoPatchelf is invoked during some of the
phases of a build and allows to add arbitrary shared objects to the
search path.
So far the same functionality was in autoPatchelf itself, but not
available as a separate function, so when adding shared objects to the
dependency cache one would have to do so manually.
The function also has the --no-recurse flag, which prevents recursing
into subdirectories.
