Avoid needless work and throwing away invariants.
These conversions date back to when `StorePath` was in Rust and there
were issues with it missing utility methods.
Previously, getDefaultNixPath was called too early: at initialisation
time, before CLI and config have been processed, when `restrictEval` and
`pureEval` both have their default value `false`. Call it when
initialising the EvalState instead, and use `setDefault`.
clangStdenv compiles with a single warning:
```
warning: destructor called on non-final 'nix::PosAdapter' that has virtual functions but non-virtual destructor [-Wdelete-non-abstract-non-virtual-dtor]
```
This fixes the warning by making the destructor of PosAdapter virtual,
deffering to the correct destructor from the concrete child classes.
This has no impact in the end, as none of these classes have specific
destructors.
Technicaly, it may be faster not to have this indirection, but as per
the warning, there is only one place where we have to delete abstract
PosAdapter values.
Not worth bikesheding I guess.
It is still necessary.
Please do your research, or f ask the author, which happens to be me.
An evaluator like this is not an environment where "it compiles, so
it works" will ever hold.
This reverts commit 1c40182b12.
Add an `$` at the end of the `grep` regex. Without it, `checkRef foo`
would always imply `checkRef foo.drv`. We want to tell these situations
apart to more precisely test what is going on.
The issue *seems* to be the cross jobs, which are missing the `CXXFLAGS`
needed to get rapidcheck.
PR #6538 would be really nice to resurrect which will prevent the
`configureFlags` from going out of sync between the regular build and
the cross build again.
Allows checking directory entry type of a single file/directory.
This was added to optimize the use of `builtins.readDir` on some
filesystems and operating systems which cannot detect this information
using POSIX's `readdir`.
Previously `builtins.readDir` would eagerly use system calls to lookup
these filetypes using other interfaces; this change makes these
operations lazy in the attribute values for each file with application
of `builtins.readFileType`.
We had some local variables left over from the older (more
complicated) implementation of this function. They should all be unused,
but one wasn't by mistake.
Delete them all, and replace the one that was still in use as intended.
