John Ericson 03a6ca9b25 tests/functional/nix-profile.sh: Add missing --no-link
Otherwise we get a stray `tests/functional/result`, which can cause
spurious failures later.

(I got a failure because the test temp dir effecting the store dir
changed. This caused a test later because Nix didn't want to remove the
old `result` because it wasn't pointing inside the new Nix store.)

Las Safin f61d951909
Avoid unnecessary copy of goal log
The data was (accidentally?) copied into a std::string,
even though the string is immediately converted into a std::string_view.
The code has been changed to construct a std::string_view directly,
such that one copy less happens.

Robert Hensing 7e5fa5c25c doc/glossary: Define package and package attribute set
A small step towards https://github.com/NixOS/nix/issues/6507

I believe this incomplete definition is one that can be agreed on.
It would be nice to define more, but considering that the issue
also proposes changes to the design, I believe we should hold off
on those.

As for the wording, we're dealing with some very general and vague
terms, that have to be treated with exactly the right amount of
vagueness to be effective.

I start out with a fairly abstract definition of package.
1. to establish a baseline so we know what we're talking about
2. so that we can go in and clarify that we have an extra, Nix-specific
   definition.

"Software" is notoriously ill-defined, so it makes a great qualifier
for package, which we don't really want to pin down either, because
that would just get us lost in discussion.
We can come back to this after we've done 6057 and a few years in a
desert cave.

Then comes the "package attribute set" definition.
I can already hear Valentin say "That's not even Nix's responsibility!"
and on some days I might even agree.
However, in our current reality, we have `nix-env`, `nix-build` and
`nix profile`, which query the `outputName` attribute - among others -
which just don't exist in the derivation.

For those who can't believe what they're reading:

    $ nix-build --expr 'with import ./. {}; bind // {outputName = "lib";}' --no-out-link
    this path will be fetched (1.16 MiB download, 3.72 MiB unpacked):
      /nix/store/rfk6klfx3z972gavxlw6iypnj6j806ma-bind-9.18.21-lib
    copying path '/nix/store/rfk6klfx3z972gavxlw6iypnj6j806ma-bind-9.18.21-lib' from 'https://cache.nixos.org'...
    /nix/store/rfk6klfx3z972gavxlw6iypnj6j806ma-bind-9.18.21-lib

and let me tell you that bind is not a library.

So anyway, that's also proof of why calling this a "derivation attrset" would be wrong, despite the type attribute.

doc: provide context in glossary definitions (#9378) 2024-01-13 12:20:08 +01:00
John Ericson e739a5002d Avoid Windows macros in the parser and lexer
`FLOAT`, `INT`, and `IN` are identifers taken by macros.

The name `IN_KW` is chosen to match `OR_KW`, which is presumably named
that way for the same reason of dodging macros.

Separate `SystemError` from `SysError`

John Ericson 6208ca7209 Separate SystemError from SysError
Most of this is a `catch SysError` -> `catch SystemError` sed. This
is a rather pure-churn change I would like to get out of the way. **The
intersting part is `src/libutil/error.hh`.**

On Unix, we will only throw the `SysError` concrete class, which has
the same constructors that `SystemError` used to have.

On Windows, we will throw `WinError` *and* `SysError`. `WinError`
(which will be created in a later PR), will use a `DWORD` instead of
`int` error value, and `GetLastError()`, which is the Windows equivalent
of the `errno` machinery. Windows will *also* use `SysError` because
Window's "libc" (MSVCRT) implements the POSIX interface, and we use it
too.

As the docs describe, while we *throw* one of the 3 choices above (2
concrete classes or the alias), we should always *catch* `SystemError`.
This ensures no matter how the implementation changes for Windows (e.g.
between `SysError` and `WinError`) the catching logic stays the same
and stays correct.

Mel Zuser 25c889baac Fix performance of builtins.substring for empty substrings
When returning a 0-length substring, avoid calling coerceToString,
since it returns a string_view with the string's length, which is
expensive to compute for large strings.
