@vcunat and others rightly point out that it's easier to quote always,
than learn Bash's idiosyncrasies enough to know when it doesn't make a
difference.
This reverts commit 2743078f66, which
removes quotes that don't do anything, and then goes further adding
even more quotes.
The logic was made pure for the normal libSystem, but this change never
made it to the bootstrap tools. Deduplication the logic as the comment
suggests would have prevented this, but here's a stop-gap until we do
so.
`nix-build pkgs/top-level/release.nix -A tarball` now succeeds.
`configureFlags = null` lead to a type error, and one overrideDrv
needed to be converted to to append a configureFlags list instead of
string due to the normalization.
Thanks @vcunat for alerting me to the issues---sorry I did not catch
them before merging my own PR.
Eventually the adapter will be removed. Moved is
- Name suffix from hostPlatform
- configurePlatforms
To not cause more breakage, the default is currently [], but
eventually it will be [ "build" "host" ], as the cross adapter makes
it today.
I took some liberties with the flags-echoing code to make it more
concise and correct. Also, a few warnings in findInputs and friends I
skipped because I am going to rewrite those anyways.
Thanks @grahamc for telling me about this great linter!
The main changes are in libSystem, which lost the coretls component in 10.13
and some hardening changes that quietly crash any program that uses %n in
a non-constant format string, so we've needed to patch a lot of programs that
use gnulib.
This makes those files a bit easier to read. Also, for what it's worth,
it brings us one baby step closer to handling spaces in store paths.
Also, I optimized handling of many transitive deps with read. Probably,
not very beneficial, but nice to enforce the pkg-per-line structure.
Doing so let me find much dubious code and fix it.
Two misc notes:
- `propagated-user-env-packages` also needed to be adjusted as
sometimes it is copied to/from the propagated input files.
- `local fd` should ensure that file descriptors aren't clobbered
during recursion.
Only cosmetic changes are done otherwise.
Real refactoring is left for later.
There's a small slow-down on my machine:
$ time nix-env -qa -P >/dev/null
gets from ~2.8 to ~3.5 seconds (negligible change in RAM).
That's most likely caused by sharing less computation between different
mkDerivation calls, and I plan to improve that soon.
This is a bit simpler now, but more importantly it scales better when I
double the number of sorts of dependencies as part of my cross
compilation work.
Packages get --host and --target by default, but can explicitly request
any subset to be passed as needed. See docs for more info.
