the makeInstalledTests function in `nixos/tests/installed-tests/default.nix` isn't available outside of nixpkgs so
it's not a breaking change
The sole consumer in Nixpkgs of `releaseTools.antBuild` is
`pkgs/development/libraries/junit`, which has been broken since
2015-09-08. The sole consumer in Nixpkgs of `junit` is
`pkgs/development/libraries/junixsocket`, which hasn't built due to
`junit` since 2015-09-08. All three are removed due to their obvious
lack of use.
All other packages in Nixpkgs depending on junit consume
`pkgs/development/java-modules/junit`, which is not broken.
Any downstreams that have kept using these `junit` or `junixsocket`
packages since 2015-09-08 have basically already vendored the packages
via patching them, so no aliases are provided.
Somewhere after #110628, which replaced stdenv.lib with lib, up to
bug #134572, lib got removed from the argument list, breaking any
invocations of debBuild. This adds it back.
Without this fix, I can no longer build anything with releaseTools.nixBuild {}. A job typically fails with:
$ nix-build release.nix -A build.basic.x86_64-linux --show-trace
error: while evaluating the attribute 'lib' of the derivation 'libnixxml-0.1pre1234' at /home/sander/teststuff/nixpkgs/pkgs/build-support/release/nix-build.nix:89:5:
cannot coerce a set to a string, at /home/sander/teststuff/nixpkgs/pkgs/build-support/release/nix-build.nix:89:5
This is caused by the fact that `lib' is propagated as a parameter, which is a function. Functions cannot be converted to strings.
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.
Checkinstall had two problems:
1. when it was called without a version (e.g. with a derivation created
by fetchFromGitHub) it would use `src` as debian version, which caused
dpkg to fail
2. when dpkg failed, it would invoke the pager with the log, which hangs
the build
So now
1. the default version is the dummy `0.0.0`
2. the used pager is `cat`
These two expressions greatly simplify using the clang-analyzer or
Coverity static analyzer on your C/C++ projects. In fact, they are
identical to nixBuild in every way out of the box, and should 'Just
Work' providing your code can be compiled with Clang already.
The trick is that when running 'make', we actually just alias it to the
appropriate scan build tool, and add a post-build hook that will bundle
up the results appropriately and unalias it.
For Clang, we put the results in $out/analysis and add an 'analysis'
report to $out/nix-support/hydra-build-products pointing to the result
HTML - this means that if the analyzer finds any bugs, the HTML results
will automatically show up Hydra for easy viewing.
For Coverity, it's slightly different. Instead we run the build tool and
after we're done, we tar up the results in a format that Coverity Scan's
service understands. We put the tarball in $out/tarballs under the name
'foo-cov-int.xz' and add an entry for the file to hydra-build-products
as well for easy viewing.
Of course for Coverity you must then upload the build. A Hydra plugin to
do this is on the way, and it will automatically pick up the
cov-int.tar.xz for uploading.
Note that coverityAnalysis requires allowUnfree = true;, as well as the
cov-build tools, which you can download from https://scan.coverity.com -
they're not linked to your account or anything, it's just an annoying
registration wall.
Note this is a first draft. In particular, scan-build fixes the C/C++
compiler to be Clang, and it's perfectly reasonable to want to use Clang
for the analyzer but have scan-build invoke GCC instead.

Stdenv adapters are kinda weird and un-idiomatic (especially when they
don't actually change stdenv). It's more idiomatic to say
buildInputs = [ makeCoverageAnalysisReport ];
