Treating fixupPhase specially is really ugly. Also, it collides with
the work in the multiple-outputs branch (which already has support for
fixing up all outputs).
Partial revert of 0a44a09121.
Some programs, e.g. guile-config, has a shebang that ends in '\':
#!/usr/bin/guile-1.8 \
-e main -s
!#

This currently breaks patchShebangs:
$ read oldPath arg0 args <<< 'shebang \'; echo $?
1
$ echo $oldPath
shebang
$ echo $arg0
$ echo $args
(And setup.sh/patchShebangs is run with 'set -e' so any command that
return non-zero aborts the build.)
Fix by telling 'read' to not interpret backslashes (with the -r flag):
$ read -r oldPath arg0 args <<< 'shebang \'; echo $?
0
$ echo $oldPath
shebang
$ echo $arg0
\
$ echo $args
Also needed: escape the escape characters so that sed doesn't interpret
them.
patchShebangs has a bug that shows itself on files that have the
executable bit set but have no shebang (i.e. a blank/empty first line).
The shell would then evaluate this:
if [ != '#!' ]; then
# not evaluated
fi
With proper quoting we get the correct behaviour:
if [ "" != '#!' ]; then
# this will be evaluated
fi
When building e.g. perl for the first time there is no perl in PATH yet,
so command -v perl will fail.
This brings back the previous behaviour of silently not patching
shebangs for which there is no available command in PATH.
Currently "/usr/bin/env python" is rewritten to "/nix/store/.../env
python". That doesn't really improve anything because the interpreter
still have to be located in $PATH at runtime. The result is that many
nix package expressions do .../bin/env fixup themselves.
Instead of everyone having to do this patching locally, add the
functionality to the standard environment patchShebangs function so that
everyone can benefit.
set CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH based on NIX_CFLAGS_COMPILE and
NIX_LDFLAGS so that cmake's find_library like functions find all the libraries
gcc knows about thanks to the gcc wrapper
This is particular useful with myEnvFun which then also sets those CMAKE_* env
variables.`
Because setup.sh has to change this causes many rebuilds - thus it should be
included in a stdenv-update like branch
Also cmake builds in parallel perfectly fine
update cmake to latest minor number, I didn't change the patches,
just reapplied them manually recordin a new patch
I'm not sure whether this was by intention, but so far postPatch hooks were
silently skipped whenever the patches list was empty. This change could possibly
change the build results of the following packages:
* gcc
* cmake (264)
* systemtap
* quemu-kvm
These packages all have in common that they have a postPatch hook and the
patches list can be empty when certain conditions are met.

This is for consistency with terminology in stdenv (and the terms
"hostDrv" and "buildDrv" are not very intuitive, even if they're
consistent with GNU terminology).
This allows various applications. It allows users to set global
optimisation flags, e.g.
stdenv.userHook = ''NIX_CFLAGS_COMPILE+=" -funroll-loops"'';
But the impetus is as an alternative to issue #229, allowing impure
stdenv setup for people who want to use distcc:
stdenv.userHook = "source /my/impure/setup-script.sh";
This is probably a bad idea, but at least now it's a bad idea in
people's configuration and not in Nixpkgs. :-)
bash's pattern replacement feature. "replace-literal" is an
uncommon command so it was a headache during the bootstrap.

These markers follow the format of those of `nix-store --print-build-trace',
which allows extraction of, say, phase durations in a similar way.
