When I stop a download with Ctrl-C in a `nix repl` of a flake, the REPL
refuses to do any other downloads:
nix-repl> builtins.getFlake "nix-serve"
[0.0 MiB DL] downloading 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca41 error: download of 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca416e5a9415d4972b0f0' was interrupted

nix-repl> builtins.getFlake "nix-serve"
error: interrupted by the user

To fix this issue, two changes were necessary:
* Reset the global `_isInterrupted` variable: only because a single
operation was aborted, it should still be possible to continue the
session.
* Recreate a `fileTransfer`-instance if the current one was shut down by
an abort.

The min bound written corresponds to the date of the commit that
introduced the change, but it only got merged on master some weeks
later. Since the version is essentially the commit date, that means that
there’s a whole range of commits on master (including the current
`nixUnstable`) that have a higher version but don’t contain the required
change.
(cherry picked from commit b598e5c47c)
Noticed this minor logging deficiency when debugged --disable-shared
build:
LD
AR
LD
CXX src/libstore/local-store.o
After the change build is logged as expected:
LD src/libmain/libnixmain.a
LD src/libfetchers/libnixfetchers.a
AR src/libmain/libnixmain.a
CXX src/libstore/local-store.o
(cherry picked from commit f147f42f46)
This reverts some parts of commit
8430a8f086 which was trying to rethrow
some exceptions while we weren’t in the context of a `catch` block,
causing some weird “terminate called without an active exception”
errors.
Fix#5368
(cherry picked from commit 7466048d39)
In https://github.com/NixOS/nix/pull/5350 we noticed link failures
pkgsStatic.nixUnstable. Adding explicit dependency on libutil fixes
libstore-tests linking.
(cherry picked from commit d7d6fe44d6)
We now build the context (so this has the side-effect of making
builtins.{path,filterSource} work on derivations outputs, if IFD is
enabled) and then check that the path has no references (which is what
we really care about).
The boolean is only used to determine if the formals are set to a
non-null pointer in all our cases. We can get rid of that allocation and
instead just compare the pointer value with NULL. Saving up to
sizeof(bool) + platform specific alignment per ExprLambda instace.
Probably not a lot of memory but perhaps a few kilobyte with nixpkgs?
This also gets rid of a potential issue with dereferencing formals based on
the value of the boolean that didn't have to be aligned with the formals
pointer but was in all our cases.
9c766a40cb broke logging from the
daemon, because commonChildInit is called when starting the build hook
in a vfork, so it ends up resetting the parent's logger. So don't
vfork.
It might be best to get rid of vfork altogether, but that may cause
problems, e.g. when we call an external program like git from the
evaluator.
