Make thread disabling explicit. This changes the semantics of the perl
derivation, so on other platforms it may require setting
enableThreading = false
This commit doesn't change the derivation or out hash of stdenvLinux.
The stage3.extraAttrs.glibc argument was required for this whole build
procedure to correctly work and it was very-very hard to see why (the
comment said something about gcc47, but we're using gcc48 now).
This stage3.extraAttrs.glibc goes into stage3.stdenv.glibc after some
arg passing, and in pkgs/development/compiler/gcc an (stdenv ? glibc)
boolean expression decides to override /usr/include during the GCC
build.
All of our stages are built with glibc, so this refactoring moves this
repeating specification of glibc (once for gcc wrapper and once here for
extraAttrs) to stageFun, by getting rid of wrapGCC, as we were using
that in all of the stages anyways.
Incidentally it turned out, that this stdenv.glibc inconsistency caused
some random other stuff to behave differently:
- stage1.pkgs.perl has threading disabled,
- stage4.pkgs.coreutils (the production coreutils) has testing disabled.
Leave this historical accidents as they are in this commit, so the scope
of this commit can stay as a refactoring only, these issues will be
fixed in separate commits.
This commit doesn't change the derivation or the output hash of
stdenvLinux.
Use the new allowedRequisites feature in stdenvLinux.
This way we properly check that the end-result stdenv of the quite
complicated multi-stage stdenvLinux building procedure is sane, and only
depends on the stuff that we know about.
Alternative would be to just disallowRequisites bootstrapTools, which is
the most common offender, but we have had other offenders in the past.
For these checks to actually fire, you currently have to use nixUnstable,
as the necessary feature will be released in Nix 1.8.
Previously stdenv depended on two different zlibs and there was a third
one in the top-level package set for other purposes. This commit merges
all this zlibs to one.
Actually this have been committed once as 1f2b636, but then got lost
while resolving merge conflicts. Hopefully it survives this time.
1) Make the core python libraries deterministic.
2) Make the python libraries created by glib deterministic.
@vcunat put back the removal of share/gtk-doc in glib.
I don't know why they feel they need to check the compatibility by build date,
so I would keep check against $out, which is a better nix equivalent.
Also, expression refactoring (put comments out of hash-changing bash).
The old expression was broken. This began as an attempt to fix it, but
the new expression is substantially different. It takes advantage of new
features that obviate the need to patch Hoogle. It comes with several
limitations. The new expression does not build the database in parallel,
although it does not take long. The new expression also does not support
downloading databases from the Hoogle instance at haskell.org; those
databases link to Hackage for documentation, defying the meaning of local.
The zip file contains files named CHANGELOG and ChangeLog, so the
build fails on case-insensitive systems with:
error: creating file `/nix/store/nix-4888-0/unpacked/ChangeLog': File exists
The official tar distribution does not have this problem.
