synopsis: Define integer overflow in the Nix language as an error
|
||||
issues: [fj#423]

|

|
||||
Previously, integer overflow in the Nix language invoked C++ level signed overflow, which was undefined behaviour, but *probably* manifested as wrapping around on overflow.
|
||||
|
||||
Since prior to the public release of Lix, Lix had C++ signed overflow defined to crash the process and nobody noticed this having accidentally removed overflow from the Nix language for three months until it was caught by fiddling around.
|
||||
Given the significant body of actual Nix code that has been evaluated by Lix in that time, it does not appear that nixpkgs or much of importance depends on integer overflow, so it is safe to turn into an error.
|
||||
|
||||
Some other overflows were fixed:
|
||||
- `builtins.fromJSON` of values greater than the maximum representable value in a signed 64-bit integer will generate an error.
|
||||
- `nixConfig` in flakes will no longer accept negative values for configuration options.
|
||||
|
||||
Integer overflow now looks like the following:
|
||||
|
||||
```
|
||||
» nix eval --expr '9223372036854775807 + 1'
|
||||
error: integer overflow in adding 9223372036854775807 + 1

||||

Previously, if an attribute path selection expression like `linux_4_9.meta.description` it wouldn't show you which one of those parts in the attribute path, or even that that line of code is what caused evaluation of the failing expression.

The previous error looks like this:

The io\_uring API has the unfortunate property that it is not possible to selectively decide which operations should be allowed.
|
||||
This, together with the fact that new operations are routinely added, makes it a hazard to the proper function of the sandbox.
|
||||
|
||||
Therefore, any access to io\_uring has been made unavailable inside the sandbox.
|
||||
As such, attempts to execute any system calls forming part of this API will fail with the error `ENOSYS`, as if io\_uring support had not been configured into the kernel.

`build-dir` can now be set in the Nix configuration to choose the backing directory for the build sandbox.
|
||||
This can be useful on systems with `/tmp` on tmpfs, or simply to relocate large builds to another disk.
|
||||
|
||||
Also, `XDG_RUNTIME_DIR` is no longer considered when selecting the default temporary directory,
|
||||
as it's not intended to be used for large amounts of data.

synopsis: Deprecated language features

|

|

A system for deprecation (and then the planned removal) of undesired language features has been put into place.
|
||||
It is controlled via feature flags much like experimental features, except that the deprecations are enabled default,
|
||||
and can be disabled via the flags for backwards compatibility (opt-out with `--extra-deprecated-features` or the Nix configuration file).
|
||||
|
||||
- `url-literals`: **URL literals** have long been obsolete and discouraged of use, and now they are officially deprecated.
|
||||
This means that all URLs must be properly put within quotes like all other strings.
|
||||
- `rec-set-overrides`: **__overrides** is an old arcane syntax which has not been in use for more than a decade.
|
||||
It is soft-deprecated with a warning only, with the plan to turn that into an error in a future release.
|
||||
- `ancient-let`: **The old `let` syntax** (`let { body = …; … }`) is soft-deprecated with a warning as well. Use the regular `let … in` instead.

synopsis: "Distinguish between explicit throws and errors that happened while evaluating a throw"
|

|
||||
|
||||
Previously, errors caused by an expression like `throw "invalid argument"` were treated like an error that happened simply while some builtin function was being called:
|
||||
|
||||
```
|
||||
let
|
||||
throwMsg = p: throw "${p} isn't the right package";
|
||||
in throwMsg "linuz"
|
||||
|
||||
error:
|
||||
… while calling the 'throw' builtin
|
||||
at «string»:2:17:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg "linuz"
|
||||
|
||||
error: linuz isn't the right package
|
||||
```
|
||||
|
||||
But the error didn't just happen "while" calling the `throw` builtin — it's a throw error!
|
||||
Now it looks like this:
|
||||
|
||||
```
|
||||
let
|
||||
throwMsg = p: throw "${p} isn't the right package";
|
||||
in throwMsg "linuz"
|
||||
|
||||
error:
|
||||
… caused by explicit throw
|
||||
at «string»:2:17:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg "linuz"
|
||||
|
||||
error: linuz isn't the right package
|
||||
```
|
||||
|
||||
This also means that incorrect usage of `throw` or errors evaluating its arguments are easily distinguishable from explicit throws:
|
||||
|
||||
```
|
||||
let
|
||||
throwMsg = p: throw "${p} isn't the right package";
|
||||
in throwMsg { attrs = "error when coerced in string interpolation"; }
|
||||
|
||||
error:
|
||||
… while calling the 'throw' builtin
|
||||
at «string»:2:17:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg { attrs = "error when coerced in string interpolation"; }
|
||||
|
||||
… while evaluating a path segment
|
||||
at «string»:2:24:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg { attrs = "error when coerced in string interpolation"; }
|
||||
|
||||
error: cannot coerce a set to a string: { attrs = "error when coerced in string interpolation"; }
|
||||
```
|
||||
|
||||
Here, instead of an actual thrown error, a type error happens first (trying to coerce an attribute set to a string), but that type error happened *while* calling `throw`.

`nix-collect-garbage --dry-run` did not previously give any output - it simply

Now, when building fixed-output derivations, Lix will guess the URL that was used in the derivation using the `url` or `urls` properties in the derivation environment.
|

This is a layering violation but making these diagnostics tractable when there are multiple instances of the `AAAA` hash is too significant of an improvement to pass it up.

current activities below each other for better visibility.
|

|

These formats attempt to use the maximum available lines
|

The status bar is displayed as the first line, with each subsequent

CppNix 2.3 was released in 2019, and is the new oldest supported version. We
|
||||
will increase our support baseline in the future up to a final version of CppNix
|
||||
2.18 (which may happen soon given that it is the only still-packaged and thus
|
||||
still-tested >2.3 version), but this step already removes a significant amount
|
||||
of dead, untested, code paths.
|
||||
|
||||
Lix speaks the same version of the protocol as CppNix 2.18 and that fact will
|
||||
never change in the future; the Lix plans to replace the protocol for evolution
|
||||
will entail a complete incompatible replacement that will be supported in
|
||||
parallel with the old protocol. Lix will thus retain remote build compatibility
|
||||
with CppNix as long as CppNix maintains protocol compatibility with 2.18, and
|
||||
as long as Lix retains legacy protocol support (which will likely be a long
|
||||
time given that we plan to convert it to a frozen-in-time shim).

|

Some inconsistent and surprising behaviours have been eliminated from the pretty-printing used by the REPL and `nix eval`:
|
||||
* Lists and attribute sets that contain only a single item without nested structures are no longer sometimes inappropriately indented in the REPL, depending on internal state of the evaluator.
|
||||
* Empty attribute sets and derivations are no longer shown as `«repeated»`, since they are always cheap to print.
|
||||
This matches the existing behaviour of `nix-instantiate` on empty attribute sets.
|
||||
Empty lists were never printed as `«repeated»` already.
|
||||
* The REPL by default does not print nested attribute sets and lists, and indicates elided items with an ellipsis.
|
||||
Previously, the ellipsis was printed even when the structure was empty, so that such items do not in fact exist.
|
||||
Since this behaviour was confusing, it does not happen any more.
|
||||

||||

Calling `:edit` from the repl now only reloads if the file being edited was outside of Nix store.

That means that all the local variables are now preserved across `:edit`s of store paths.

This is always safe because the store is read-only.

This section describes the notion of *deprecated features*, and how it fits into the big picture of the development of Lix.
|
||||
|
||||
# What are deprecated features?
|
||||
|
||||
Deprecated features are disabled by default, with the intent to eventually remove them.
|
||||
Users must explicitly enable them to keep using them, by toggling the associated [deprecated feature flags](@docroot@/command-ref/conf-file.md#conf-deprecated-features).
|
||||
This allows backwards compatibility and a graceful transition away from undesired features.
|
||||
|
||||
# Which features can be deprecated?
|
||||
|
||||
Undesired features should be soft-deprecated by yielding a warning when used for a significant amount of time before the can be deprecated.
|
||||
Legacy obsolete feature with little to no usage may go through this process faster.
|
||||
Deprecated features should have a migration path to a preferred alternative.
|
||||
|
||||
# Lifecycle of a deprecated feature
|
||||
|
||||
This description is not normative, but a feature removal may roughly happen like this:
|
||||
|
||||
1. Add a warning when the feature is being used.
|
||||
2. Disable the feature by default, putting it behind a deprecated feature flag.
|
||||
- If disabling the feature started out as an opt-in experimental feature, turn that experimental flag into a no-op or remove it entirely.
|
||||
For example, `--extra-experimental-features=no-url-literals` becomes `--extra-deprecated-features=url-literals`.
|
||||
3. Decide on a time frame for how long that feature will still be supported for backwards compatibility, and clearly communicate that in the error messages.
|
||||
- Sometimes, automatic migration to alternatives is possible, and such should be provided if possible
|
||||
- At least one NixOS release cycle should be the minimum
|
||||
4. Finally remove the feature entirely, only keeping the error message for those still using it.
|
||||
|
||||
# Relation to language versioning
|
||||
|
||||
Obviously, removing anything breaks backwards compatibility.
|
||||
In an ideal world, we'd have SemVer controls over the language and its features, cleanly allowing us to make breaking changes.
|
||||
See https://wiki.lix.systems/books/lix-contributors/page/language-versioning and [RFC 137](https://github.com/nixos/rfcs/pull/137) for efforts on that.
|
||||
However, we do not live in such an ideal world, and currently this goal is so far away, that "just disable it with some back-compat for a couple of years" is the most realistic solution, especially for comparatively minor changes.

|

|
||||
*This language feature is still experimental and may change at any time. Enable `--extra-experimental-features pipe-operator` to use it.*
|
||||
|
||||
Pipes are a dedicated operator for function application, but with reverse order and a lower binding strength.
|
||||
This allows you to chain function calls together in way that is more natural to read and requires less parentheses.
|
||||
|
||||
`a |> f b |> g` is equivalent to `g (f b a)`.
|
||||
`g <| f b <| a` is equivalent to `g (f b a)`.
|
||||
|
||||
Example code snippet:
|
||||
|
||||
```nix
|
||||
defaultPrefsFile = defaultPrefs
|
||||
|> lib.mapAttrsToList (
|
||||
key: value: ''
|
||||
// ${value.reason}
|
||||
pref("${key}", ${builtins.toJSON value.value});
|
||||
''
|
||||
)
|
||||
|> lib.concatStringsSep "\n"
|
||||
|> pkgs.writeText "nixos-default-prefs.js";
|
||||
```
|
||||
|
||||
Note how `mapAttrsToList` is called with two arguments (the lambda and `defaultPrefs`),
|
||||
but moving the last argument in front of the rest improves the reading flow.
|
||||
This is common for functions with long first argument, including all `map`-like functions.

## Breaking Changes
|
||||
- Block io_uring in the Linux sandbox [cl/1611](https://gerrit.lix.systems/c/lix/+/1611)
|
||||
|
||||
The io\_uring API has the unfortunate property that it is not possible to selectively decide which operations should be allowed.
|
||||
This, together with the fact that new operations are routinely added, makes it a hazard to the proper function of the sandbox.
|
||||
|
||||
Therefore, any access to io\_uring has been made unavailable inside the sandbox.
|
||||
As such, attempts to execute any system calls forming part of this API will fail with the error `ENOSYS`, as if io\_uring support had not been configured into the kernel.
|
||||

||||

|
||||
- The `build-hook` setting is now deprecated
|
||||
|
||||
Build hooks communicate with the daemon using a custom, internal, undocumented protocol that is entirely unversioned and cannot be changed.
|
||||
Since we intend to change it anyway we must unfortunately deprecate the current build hook infrastructure.
|
||||
We do not expect this to impact most users—we have not found any uses of `build-hook` in the wild—but if this does affect you, we'd like to hear from you!
|
||||
- Lix no longer speaks the Nix remote-build worker protocol to clients or servers older than CppNix 2.3 [fj#325](https://git.lix.systems/lix-project/lix/issues/325) [cl/1207](https://gerrit.lix.systems/c/lix/+/1207) [cl/1208](https://gerrit.lix.systems/c/lix/+/1208) [cl/1206](https://gerrit.lix.systems/c/lix/+/1206) [cl/1205](https://gerrit.lix.systems/c/lix/+/1205) [cl/1204](https://gerrit.lix.systems/c/lix/+/1204) [cl/1203](https://gerrit.lix.systems/c/lix/+/1203) [cl/1479](https://gerrit.lix.systems/c/lix/+/1479)
|
||||
|
||||
CppNix 2.3 was released in 2019, and is the new oldest supported version. We
|
||||
will increase our support baseline in the future up to a final version of CppNix
|
||||
2.18 (which may happen soon given that it is the only still-packaged and thus
|
||||
still-tested >2.3 version), but this step already removes a significant amount
|
||||
of dead, untested, code paths.
|
||||
|
||||
Lix speaks the same version of the protocol as CppNix 2.18 and that fact will
|
||||
never change in the future; the Lix plans to replace the protocol for evolution
|
||||
will entail a complete incompatible replacement that will be supported in
|
||||
parallel with the old protocol. Lix will thus retain remote build compatibility
|
||||
with CppNix as long as CppNix maintains protocol compatibility with 2.18, and
|
||||
as long as Lix retains legacy protocol support (which will likely be a long
|
||||
time given that we plan to convert it to a frozen-in-time shim).

## Features

- Pipe operator `|>` (experimental) [fj#438](https://git.lix.systems/lix-project/lix/issues/438) [cl/1654](https://gerrit.lix.systems/c/lix/+/1654)
|
||||
|
||||
Implementation of the pipe operator (`|>`) in the language as described in [RFC 148](https://github.com/NixOS/rfcs/pull/148).
|
||||
The feature is still marked experimental, enable `--extra-experimental-features pipe-operator` to use it.

||||

||||
Previously, if an attribute path selection expression like `linux_4_9.meta.description` it wouldn't show you which one of those parts in the attribute path, or even that that line of code is what caused evaluation of the failing expression.

||||

||||
|
||||
```

||||

- Confusing 'invalid path' errors are now 'path does not exist' [cl/1161](https://gerrit.lix.systems/c/lix/+/1161) [cl/1160](https://gerrit.lix.systems/c/lix/+/1160) [cl/1159](https://gerrit.lix.systems/c/lix/+/1159)
|
||||
|
||||
Previously, if a path did not exist in a Nix store, it was referred to as the internal name "path is invalid".
|
||||
This is, however, very confusing, and there were numerous such errors that were exactly the same, making it hard to debug.
|
||||
These errors are now more specific and refer to the path not existing in the store.
|
||||

||||

- Add a `build-dir` setting to set the backing directory for builds [gh#10303](https://github.com/NixOS/nix/pull/10303) [gh#10312](https://github.com/NixOS/nix/pull/10312) [gh#10883](https://github.com/NixOS/nix/pull/10883) [cl/1514](https://gerrit.lix.systems/c/lix/+/1514)
|
||||
|
||||
`build-dir` can now be set in the Nix configuration to choose the backing directory for the build sandbox.
|
||||
This can be useful on systems with `/tmp` on tmpfs, or simply to relocate large builds to another disk.
|
||||
|
||||
Also, `XDG_RUNTIME_DIR` is no longer considered when selecting the default temporary directory,
|
||||
as it's not intended to be used for large amounts of data.

- Better usage of colour control environment variables [cl/1699](https://gerrit.lix.systems/c/lix/+/1699) [cl/1702](https://gerrit.lix.systems/c/lix/+/1702)
|
||||
|
||||
Lix now heeds `NO_COLOR`/`NOCOLOR` for more output types, such as that used in `nix search`, `nix flake metadata` and similar.
|
||||
|
||||
It also now supports `CLICOLOR_FORCE`/`FORCE_COLOR` to force colours regardless of whether there is a terminal on the other side.
|
||||
|
||||
It now follows rules compatible with those described on <https://bixense.com/clicolors/> with `CLICOLOR` defaulted to enabled.
|
||||
|
||||
That is to say, the following procedure is followed in order:
|
||||
- NO_COLOR or NOCOLOR set
|
||||
|
||||
Always disable colour
|
||||
- CLICOLOR_FORCE or FORCE_COLOR set
|
||||
|
||||
Enable colour
|
||||
- The output is a tty; TERM != "dumb"
|
||||
|
||||
Enable colour
|
||||
- Otherwise
|
||||
|
||||
Disable colour
|
||||
|
||||
Many thanks to [jade](https://git.lix.systems/jade) for this.
|
||||
- Distinguish between explicit throws and errors that happened while evaluating a throw [cl/1511](https://gerrit.lix.systems/c/lix/+/1511)
|
||||
|
||||
Previously, errors caused by an expression like `throw "invalid argument"` were treated like an error that happened simply while some builtin function was being called:
|
||||
|
||||
```
|
||||
let
|
||||
throwMsg = p: throw "${p} isn't the right package";
|
||||
in throwMsg "linuz"
|
||||
|
||||
error:
|
||||
… while calling the 'throw' builtin
|
||||
at «string»:2:17:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg "linuz"
|
||||
|
||||
error: linuz isn't the right package
|
||||
```
|
||||
|
||||
But the error didn't just happen "while" calling the `throw` builtin — it's a throw error!
|
||||
Now it looks like this:
|
||||
|
||||
```
|
||||
let
|
||||
throwMsg = p: throw "${p} isn't the right package";
|
||||
in throwMsg "linuz"
|
||||
|
||||
error:
|
||||
… caused by explicit throw
|
||||
at «string»:2:17:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg "linuz"
|
||||
|
||||
error: linuz isn't the right package
|
||||
```
|
||||
|
||||
This also means that incorrect usage of `throw` or errors evaluating its arguments are easily distinguishable from explicit throws:
|
||||
|
||||
```
|
||||
let
|
||||
throwMsg = p: throw "${p} isn't the right package";
|
||||
in throwMsg { attrs = "error when coerced in string interpolation"; }
|
||||
|
||||
error:
|
||||
… while calling the 'throw' builtin
|
||||
at «string»:2:17:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg { attrs = "error when coerced in string interpolation"; }
|
||||
|
||||
… while evaluating a path segment
|
||||
at «string»:2:24:
|
||||
1| let
|
||||
2| throwMsg = p: throw "${p} isn't the right package";
|
||||
| ^
|
||||
3| in throwMsg { attrs = "error when coerced in string interpolation"; }
|
||||
|
||||
error: cannot coerce a set to a string: { attrs = "error when coerced in string interpolation"; }
|
||||
```
|
||||
|
||||
Here, instead of an actual thrown error, a type error happens first (trying to coerce an attribute set to a string), but that type error happened *while* calling `throw`.

- Hash mismatch diagnostics for fixed-output derivations include the URL [cl/1536](https://gerrit.lix.systems/c/lix/+/1536)
|
||||
|
||||
Now, when building fixed-output derivations, Lix will guess the URL that was used in the derivation using the `url` or `urls` properties in the derivation environment.
|
||||
This is a layering violation but making these diagnostics tractable when there are multiple instances of the `AAAA` hash is too significant of an improvement to pass it up.
|
||||
|
||||
```
|
||||
error: hash mismatch in fixed-output derivation '/nix/store/sjfw324j4533lwnpmr5z4icpb85r63ai-x1.drv':

- Add log formats `multiline` and `multiline-with-logs` [cl/1369](https://gerrit.lix.systems/c/lix/+/1369)
|
||||
|
||||
Added two new log formats (`multiline` and `multiline-with-logs`) that display
|
||||
current activities below each other for better visibility.
|
||||
|
||||
These formats attempt to use the maximum available lines
|
||||
(defaulting to 25 if unable to determine) and print up to that many lines.
|
||||
The status bar is displayed as the first line, with each subsequent
|
||||
activity on its own line.

- Eliminate some pretty-printing surprises [#11100](https://github.com/NixOS/nix/pull/11100) [cl/1616](https://gerrit.lix.systems/c/lix/+/1616) [cl/1617](https://gerrit.lix.systems/c/lix/+/1617) [cl/1618](https://gerrit.lix.systems/c/lix/+/1618)
|
||||
|
||||
Some inconsistent and surprising behaviours have been eliminated from the pretty-printing used by the REPL and `nix eval`:
|
||||
* Lists and attribute sets that contain only a single item without nested structures are no longer sometimes inappropriately indented in the REPL, depending on internal state of the evaluator.
|
||||
* Empty attribute sets and derivations are no longer shown as `«repeated»`, since they are always cheap to print.
|
||||
This matches the existing behaviour of `nix-instantiate` on empty attribute sets.
|
||||
Empty lists were never printed as `«repeated»` already.
|
||||
* The REPL by default does not print nested attribute sets and lists, and indicates elided items with an ellipsis.
|
||||
Previously, the ellipsis was printed even when the structure was empty, so that such items do not in fact exist.
|
||||
Since this behaviour was confusing, it does not happen any more.
|
||||
|
||||
Before:
|
||||
```
|
||||
nix-repl> :p let x = 1 + 2; in [ [ x ] [ x ] ]
|
||||
[
|
||||
[
|
||||
3
|
||||
]
|
||||

|
||||
]
|
||||
|
||||

||||

||||

||||

|
||||

|
||||

|
||||

|
||||

|

Many thanks to [alois31](https://git.lix.systems/alois31) and [Robert Hensing](https://github.com/roberth) for this.
|
||||
- `nix registry add` now requires a shorthand flakeref on the 'from' side [cl/1494](https://gerrit.lix.systems/c/lix/+/1494)
|
||||
|
||||
The 'from' argument must now be a shorthand flakeref like `nixpkgs` or `nixpkgs/nixos-20.03`, making it harder to accidentally swap the 'from' and 'to' arguments.
|
||||
|
||||
Registry entries that map from other flake URLs can still be specified in registry.json, the `nix.registry` option in NixOS, or the `--override-flake` option in the CLI, but they are not guaranteed to work correctly.
|
||||
|
||||
Many thanks to [delan](https://git.lix.systems/delan) for this.
|
||||
- Allow automatic rejection of configuration options from flakes [cl/1541](https://gerrit.lix.systems/c/lix/+/1541)
|
||||
|
||||
Setting `accept-flake-config` to `false` now respects user choice by automatically rejecting configuration options set by flakes.
|
||||
The old behaviour of asking each time is still available (and default) by setting it to the special value `ask`.
|
||||
|
||||
Many thanks to [alois31](https://git.lix.systems/alois31) for this.
|
||||
- `nix repl` now allows tab-completing the special repl :colon commands [cl/1367](https://gerrit.lix.systems/c/lix/+/1367)
|
||||
|
||||
The REPL (`nix repl`) supports pressing `<TAB>` to complete a partial expression, but now also supports completing the special :colon commands as well (`:b`, `:edit`, `:doc`, etc), if the line starts with a colon.
|
||||
|
||||
Many thanks to [Qyriad](https://git.lix.systems/Qyriad) for this.
|
||||
- `:edit`ing a file in Nix store no longer reloads the repl [fj#341](https://git.lix.systems/lix-project/lix/issues/341) [cl/1620](https://gerrit.lix.systems/c/lix/+/1620)
|
||||
|
||||
Calling `:edit` from the repl now only reloads if the file being edited was outside of Nix store.
|
||||
That means that all the local variables are now preserved across `:edit`s of store paths.
|
||||
This is always safe because the store is read-only.
|
||||
|
||||
Many thanks to [goldstein](https://git.lix.systems/goldstein) for this.
|
||||
- `:log` in repl now works on derivation paths [fj#51](https://git.lix.systems/lix-project/lix/issues/51) [cl/1716](https://gerrit.lix.systems/c/lix/+/1716)
|
||||
|
||||
`:log` can now accept store derivation paths in addition to derivation expressions.
|
||||
|
||||
Many thanks to [goldstein](https://git.lix.systems/goldstein) for this.
|
||||
|
||||
## Fixes
|
||||
- Define integer overflow in the Nix language as an error [fj#423](https://git.lix.systems/lix-project/lix/issues/423) [cl/1594](https://gerrit.lix.systems/c/lix/+/1594) [cl/1595](https://gerrit.lix.systems/c/lix/+/1595) [cl/1597](https://gerrit.lix.systems/c/lix/+/1597) [cl/1609](https://gerrit.lix.systems/c/lix/+/1609)
|
||||
|
||||
Previously, integer overflow in the Nix language invoked C++ level signed overflow, which was undefined behaviour, but *probably* manifested as wrapping around on overflow.
|
||||
|
||||
Since prior to the public release of Lix, Lix had C++ signed overflow defined to crash the process and nobody noticed this having accidentally removed overflow from the Nix language for three months until it was caught by fiddling around.
|
||||
Given the significant body of actual Nix code that has been evaluated by Lix in that time, it does not appear that nixpkgs or much of importance depends on integer overflow, so it is safe to turn into an error.
|
||||
|
||||
Some other overflows were fixed:
|
||||
- `builtins.fromJSON` of values greater than the maximum representable value in a signed 64-bit integer will generate an error.
|
||||
- `nixConfig` in flakes will no longer accept negative values for configuration options.
|
||||
|
||||
Integer overflow now looks like the following:
|
||||
|
||||
```
|
||||
» nix eval --expr '9223372036854775807 + 1'
|
||||
error: integer overflow in adding 9223372036854775807 + 1
|
||||
```
|
||||
|
||||
Many thanks to [jade](https://git.lix.systems/jade) for this.
|
||||
- Fix nix-collect-garbage --dry-run [fj#432](https://git.lix.systems/lix-project/lix/issues/432) [cl/1566](https://gerrit.lix.systems/c/lix/+/1566)
|
||||
|
||||
`nix-collect-garbage --dry-run` did not previously give any output - it simply
|
||||
exited without even checking to see what paths would be deleted.
|
||||
|
||||
```
|
||||
$ nix-collect-garbage --dry-run
|
||||
$
|
||||
```
|
||||
|
||||
We updated the behaviour of the flag such that instead it prints out how many
|
||||
paths it *would* delete, but doesn't actually delete them.
|
||||
|
||||
```
|
||||
$ nix-collect-garbage --dry-run
|
||||
finding garbage collector roots...
|
||||
determining live/dead paths...
|
||||
...
|
||||
<nix store paths>
|
||||
...
|
||||
2670 store paths deleted, 0.00MiB freed
|
||||

|
||||

- Fix unexpectedly-successful GC failures on macOS [fj#446](https://git.lix.systems/lix-project/lix/issues/446) [cl/1723](https://gerrit.lix.systems/c/lix/+/1723)
|
||||
|
||||
Has the following happened to you on macOS? This failure has been successfully eliminated, thanks to our successful deployment of advanced successful-failure detection technology (it's just `if (failed && errno == 0)`. Patent pending<sup>not really</sup>):
|
||||
|
||||
```
|
||||
$ nix-store --gc --print-dead
|
||||
finding garbage collector roots...
|
||||
error: Listing pid 87261 file descriptors: Undefined error: 0
|
||||
```
|
||||
|
||||

|
||||
- `nix copy` is now several times faster at `querying info about /nix/store/...` [fj#366](https://git.lix.systems/lix-project/lix/issues/366) [cl/1462](https://gerrit.lix.systems/c/lix/+/1462)
|
||||
|
||||
We fixed a locking bug that serialized `querying info about /nix/store/...`
|
||||
onto just one thread such that it was eating `O(paths to copy * latency)` time
|
||||
while setting up to copy paths to s3 and other stores. It is now `nproc` times
|
||||
faster.
|
||||
|
||||
Many thanks to [jade](https://git.lix.systems/jade) for this.
|
||||
|
||||
## Development
|
||||
- clang-tidy support [fj#147](https://git.lix.systems/lix-project/lix/issues/147) [cl/1697](https://gerrit.lix.systems/c/lix/+/1697)
|
||||
|
||||
`clang-tidy` can be used to lint Lix with a limited set of lints using `ninja -C build clang-tidy` and `ninja -C build clang-tidy-fix`.
|
||||
In practice, this fixes the built-in meson rule that was used the same as above being broken ever since precompiled headers were introduced.
|
||||
|
||||
Many thanks to [jade](https://git.lix.systems/jade) for this.
|
||||
- Lix now supports building with UndefinedBehaviorSanitizer [cl/1483](https://gerrit.lix.systems/c/lix/+/1483) [cl/1481](https://gerrit.lix.systems/c/lix/+/1481) [cl/1669](https://gerrit.lix.systems/c/lix/+/1669)
|
||||
|
||||
You can now build Lix with the configuration option `-Db_sanitize=undefined,address` and it will both work and pass tests with both AddressSanitizer and UndefinedBehaviorSanitizer enabled.
|
||||
To use ASan specifically, you have to set `-Dgc=disabled`, which an error message will tell you to do if necessary anyhow.
|
||||
|
||||
Furthermore, tests passing with Clang ASan+UBSan is checked on every change in CI.
|
||||
|
||||
For a list of undefined behaviour found by tooling usage, see [the gerrit topic "undefined-behaviour"](https://gerrit.lix.systems/q/topic:%22undefined-behaviour%22).

# Meson will *detect* what dependencies are needed from Cargo files; it just won't

# fetch them. The Meson 1.5 feature essentially internally translates Cargo.lock entries

# to .wrap files, and that translation is incredibly straightforward, so let's just
|

# use a simple Python script to generate the .wrap files ourselves while we wait for
|
||||
# Meson 1.5. Weirdly, it seems Meson will only detect dependencies from other
|
||||
# dependency() calls, so we have to specify lix-doc's two top-level dependencies,

# rnix and rowan, manually, and then their dependencies will be recursively translated

# into more dependency() calls.

# a fixed format, which is important as the .wrap files' basenames must match the string

# passed to `dependency()` exactly.

|

|
||||
### Web site
|
||||
|
||||
The website has various release-version dependent pieces.
|
||||
You can update them with `python3 update_version.py NEW_VERSION`, which will regenerate the affected page sources.
|
||||
|
||||
These need the release to have been done first as they need hashes for tarballs and such.
|
||||
|
||||
### NixOS module
|
||||
|
||||
The NixOS module has underdeveloped releng in it.
|
||||
Currently you have to do the whole branch-off dance manually to a `release-VERSION` branch and update the tarball URLs to point to the release versions manually.
|
||||
|
||||
FIXME: this should be unified with the `set_version.py` work in `lix-installer` and probably all the releng kept in here, or kept elsewhere.
