41d70a2fc8 return string_views from forceString* 
once a string has been forced we already have dynamic storage allocated for it,
so we can easily reuse that storage instead of copying.

derivations.cc: Use larger buffer in printString 
If we want to be careful about hitting the stack protector page, we should use `-fstack-check` instead.

Merge pull request #5949 from obsidiansystems/old-copyClosure 
Add back `copyClosure` for plain `StorePath`s
 2022-01-21 11:33:32 +01:00
John Ericson
5ee937523d Add back copyClosure for plain StorePaths 
This was removed in 2e199673a5 when
`copyPath` transitioned to use `RealisedPath`. But then in
e9848beca7 we added it back just for
`realisedPath`.

I think it is a good utility function --- one can easily imagine it
becoming optimized in the future, and copying paths *violating* the
closure is a very niche feature.

So if we have `copyPaths` for both sorts of paths, I think we should
have `copyClosure` for both sorts too.

dec7748119 Replace withBuffer by boost small_vector 
Although this will leave gaps in the stack, the performance impact
of those should be insignificant and we get a simpler solution
this way.

d038a67bd3 Fix segfault or stack overflow caused by large derivation fields 
This removes a dynamic stack allocation, making the derivation
unparsing logic robust against overflows when large strings are
added to a derivation.
Overflow behavior depends on the platform and stack configuration.

For instance, x86_64-linux/glibc behaves as (somewhat) expected:

$ (ulimit -s 20000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix)
error: stack overflow (possible infinite recursion)

$ (ulimit -s 40000; nix-instantiate tests/lang/eval-okay-big-derivation-attr.nix)
error: expression does not evaluate to a derivation (or a set or list of those)

However, on aarch64-darwin:

$ nix-instantiate big-attr.nix                                                                                                                                                                                                                                                       ~
zsh: segmentation fault  nix-instantiate big-attr.nix

This indicates a slight flaw in the single stack protection page
approach that is not encountered with normal stack frames.

e9a4abdb5d Make --repair-path also repair corrupt optimised links 
There already existed a smoke test for the link content length,
but it appears that there exists some corruptions pernicious enough
to replace the file content with zeros, and keeping the same length.

--repair-path now goes as far as checking the content of the link,
making it true to its name and actually repairing the path for such
coruption cases.

This was already accidentally disabled in ba87b08. It also no longer
appears to be beneficial, and in fact slow things down, e.g. when
evaluating a NixOS system configuration:

  elapsed time:       median =      3.8170  mean =      3.8202  stddev =      0.0195  min =      3.7894  max =      3.8600  [rejected, p=0.00000, Δ=0.36929±0.02513]

let's ignore it and hope nothing bad happens.
