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.)

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.

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`

Mel Zuser 1996105e91 added test for empty substring special case 2024-01-12 09:40:21 -08:00
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.

Restore ambiguous value printer for nix-instantiate
The Nix team has requested that this output format remain unchanged.
I've added a warning to the man page explaining that `nix-instantiate
--eval` output will not parse correctly in many situations.

Unify and refactor value printing
Previously, there were two mostly-identical value printers -- one in
`libexpr/eval.cc` (which didn't force values) and one in
`libcmd/repl.cc` (which did force values and also printed ANSI color
codes).

This PR unifies both of these printers into `print.cc` and provides a
`PrintOptions` struct for controlling the output, which allows for
toggling whether values are forced, whether repeated values are tracked,
and whether ANSI color codes are displayed.

Additionally, `PrintOptions` allows tuning the maximum number of
attributes, list items, and bytes in a string that will be displayed;
this makes it ideal for contexts where printing too much output (e.g.
all of Nixpkgs) is distracting. (As requested by @roberth in
https://github.com/NixOS/nix/pull/9554#issuecomment-1845095735)

Please read the tests for example output.

Future work:
- It would be nice to provide this function as a builtin, perhaps
  `builtins.toStringDebug` -- a printing function that never fails would
  be useful when debugging Nix code.
- It would be nice to support customizing `PrintOptions` members on the
  command line, e.g. `--option to-string-max-attrs 1000`.

John Ericson 0c3ce23754 Improve the build without GC
We don't just want to pass `--enable-gc=no`; we also want to make sure
boehmgc is not a dependency. Creating a nix-level configuration option
to do both, and then using that for the CI job, is more robust.

Merge pull request #9728 from obsidiansystems/readline-support
Improve build sytem support for readline instead of editline
2024-01-09 17:23:02 -05:00
John Ericson 2cea88dbc8 Improve build sytem support for readline instead of editline
Changes:

- CPP variable is now `USE_READLINE` not `READLINE`

- `configure.ac` supports with new CLI flag

- `package.nix` supports with new configuration option

- `flake.nix` CIs this (along with no markdown)

Remove old Ubuntu 16.04 stop-gap too, as that is now quite old.

Motivation:

- editline does not build for Windows, but readline *should*. (I am
  still working on this in Nixpkgs at this time, however. So there will
  be a follow-up Nix PR removing the windows-only skipping of the
  readline library once I am done.)

- Per
  https://salsa.debian.org/debian/nix/-/blob/master/debian/rules?ref_type=heads#L27
  and #2551, Debian builds Nix with readline. Now we better support and
  CI that build configuration.

This is picking up where #2551 left off, ensuring we test a few more
things not merely have CPP for them.
