zig test / zig build test ignore log_level

[acarrico]

Zig Version

0.10.0-dev.4280+c3d67c5c4

Steps to Reproduce and Observed Behavior

const std = @import("std");
pub const log_level: std.log.Level = .debug;

test "log" {
    std.log.err("log level err\n", .{});
    std.log.warn("log level warn\n", .{});
    std.log.info("log level info\n", .{});
    std.log.debug("log level debug\n", .{});
}

pub fn main() anyerror!void {
    std.log.err("log level err\n", .{});
    std.log.warn("log level warn\n", .{});
    std.log.info("log level info\n", .{});
    std.log.debug("log level debug\n", .{});
}

test:

zig build test -Drelease-safe
zig build test -Drelease-fast
zig test log.zig
zig run log.zig

Expected Behavior

In all cases I expect all four log messages. In reality I see one, two, or four as follows:

zig build test: err, warn
zig build test -Drelease-safe: err, warn
zig build test -Drelease-fast: err
zig test log.zig: err, warn
zig run log.zig: err, warn, info, debug

You now need to place log_level inside a struct named std_options, see #14181

Doesn't seem to work for zig test yet, but works with and without the struct for zig run. I assume it will work for test when I catch up to a newer compiler. Thanks @Vexu. Here is the new code for anyone reading this issue in the future:

const std = @import("std");

pub const std_options = struct {
    pub const log_level: std.log.Level = .debug;
};

test "log" {
    std.log.err("log level err\n", .{});
    std.log.warn("log level warn\n", .{});
    std.log.info("log level info\n", .{});
    std.log.debug("log level debug\n", .{});
}

pub fn main() anyerror!void {
    std.log.err("log level err\n", .{});
    std.log.warn("log level warn\n", .{});
    std.log.info("log level info\n", .{});
    std.log.debug("log level debug\n", .{});
}

Doesn't seem to work for zig test yet

That is a separate issue #12201
