Add pname and version to nix-env -q --json
|
|
Disable findRuntimeRoots on darwin when running tests because lsof is slow

|
Allow builtins.pathExists to check the existence of /nix/store paths
|

This makes it consitent with builtins.readDir.

Use $HOME instead of $USER
|
|
Add default for USER when unset
|
|
$USER/.nix-profile will not be a path. I think $HOME/.nix-profile was
the origininal intent.

uses $(id -u -n) when USER is unset, this is needed on some weird
setups in Docker. Fixes #971

Remove .github/FUNDING.yml

This is a much simpler fix to the 'error 9 while decompressing xz
file' problem than 78fa47a7f08a4cb6ee7061bf0bd86a40e1d6dc91. We just
do a ranged HTTP request starting after the data that we previously
wrote into the sink.
Fixes #2952, #379.

This reverts commit 78fa47a7f08a4cb6ee7061bf0bd86a40e1d6dc91.

'--substitute' was being shadowed by the regular '--substitute' (the
short-hand for '--option substitute true').
Fixes #2983.

This breaks the tarball job: https://hydra.nixos.org/build/95714570

This should finally allow us to address all cases of build errors due to
differences between release tarballs and building from git.

This is to avoid confusion as in commit
a0d29040f79b365598fe75d01f72d29ab538206b.

Also give a helpful error message on what package the user likely
has to install to make it work.

Our use of boost::coroutine2 depends on -lboost_context,
which in turn depends on `-lboost_thread`, which in turn depends
on `-lboost_system`.
I suspect that this builds on nix only because of low-level hacks
like NIX_LDFLAGS.
This commit passes the proper linker flags, thus fixing bootstrap
builds on non-nix distributions like Ubuntu 16.04.
With these changes, I can build Nix on Ubuntu 16.04 using:
./bootstrap.sh
./configure --prefix=$HOME/editline-prefix \
--disable-doc-gen \
CXX=g++-7 \
--with-boost=$HOME/boost-prefix \
EDITLINE_CFLAGS=-I$HOME/editline-prefix/include \
EDITLINE_LIBS=-leditline \
LDFLAGS=-L$HOME/editline-prefix/lib
make
where
* g++-7 comes from gcc-7 from
https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test,
* editline 1.14 from https://github.com/troglobit/editline/releases/tag/1.14.0
was installed into `$HOME/editline-prefix`
(because Ubuntu 16.04's `editline` is too old to have the function nix uses),
* boost 1.66 from
https://www.boost.org/doc/libs/1_66_0/more/getting_started/unix-variants.html
was installed into $HOME/boost-prefix (because Ubuntu 16.04 only has 1.58)
|
|
For example, Ubuntu 16.04 and many similar long-term-support distros
have older versions.

It was forgotten to be removed with
commit c5f23f10a84f568874321c04984b1a14d2dce978
and so it until now stayed unsubstituted as `HAVE_READLINE = @HAVE_READLINE@`
in Makefile.config.

As is normal for autoconf-based projects.
For example, it is a common use case to do
./configure CXXFLAGS=-O0
This did not work for nix until now, because the `CXXFLAGS=` declaration
would unconditionally erase what the user had specified.
The custom `OPTIMIZE` flag is removed, but the default `-O3` is retained;
autoconf would default to `-g -O2` by default otherwise as documented on:
https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/C-Compiler.html
https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/C_002b_002b-Compiler.html

That was incorrect, because checking the dirent type already requires
a working compiler.
It had the effect that setting e.g. `: ${CFLAGS=""}` before `AC_PROG_CC`
as per `AC_PROG_CC`'s documentation would have no effect, because
`AC_STRUCT_DIRENT_D_TYPE` would automatically set CFLASGS.
(In a followup commit `: ${CFLAGS=""}` will be used, so it's important
to get this working first.)

autotools-based systems usually allow user to
append own LDFLAGS like
LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu"
at ./configure stage
This change plumbs LDFLAGS through similar to existing CXXFLAGS variable.

And probably many other distributions.
Until now, ./configure would fail silently printing a warning
./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found
and then continuing, later failing with a C++ #error saying that some C++11
feature isn't supported (it didn't even get to the C++17 features).
This is because older distributions don't come with the
`AX_CXX_COMPILE_STDCXX_17` m4 macro.
This commit vendors that macro accordingly.
Now ./configure complains correctly:
configure: error: *** A compiler with support for C++17 language features is required.
On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with
gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
using:
./bootstrap.sh
./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)
|
|
And probably other Linux distributions with long-term support releases.
Also update manual stating what version is needed;
I checked that 1.14 is the oldest version with which current nix compiles,
and added autoconf feature checks for some functions added in that release
that nix uses.
|
|
This turns previous compiler errors complaining about missing files
into proper ./configure time errors telling the user which version
of boost is required.

The unbalanced single-quotes cause many editor syntax highlighters
to interpret the rest of the file as a string literal, making it easier
to make syntax mistakes in absence of proper highlighting.
