This fixes a regression introduced in #12298 where colors would never reset in a Windows console because the attributes would be queried on every `setColor` call, and then try to 'reset' the attributes to what it just queried (i.e. it was essentially doing a complicated no-op on .Reset).
This fixes the problem while (I think) keeping with the spirit of the changes in #12298--that is, `TTY.Config` is not specifically tied to stderr like it was before #12298. To that end, detectTTYConfig now takes a `File` and that's what gets used to query the initial attributes to reset to.
(for context, before #12298, the first `setColor` call is where the reset attributes would get queried and it would always use stderr to do it)

Closes #9484

- In #13720, expectEqualBytes was added as a standalone function
- In #13723, expectEqualSlices was made to use expectEqualBytes when the type was u8
- In this commit, expectEqualSlices has fully absorbed expectEqualBytes, and expectEqualBytes itself has been removed
For non-`u8` types, expectEqualSlices will now work similarly to expectEqualBytes (highlighting diffs in red), but will use a full line for each index and therefore will only print a maximum of 16 indexes.
|
|
This matches the language reference.
|
|
expectEqualSlices use it
`expectEqualBytes` will now truncate the hexdump of each input to a maximum window of 256 bytes, which makes it safe to use for arbitrarily large inputs. Therefore, it can be used in `expectEqualSlices` when the type is u8.

|
highlighted in red
The coloring is controlled by `std.debug.detectTTYConfig` so it will be disabled when appropriate.

Test coverage was lacking for chdir() on WASI, allowing this to
regress.
This change makes os.chdir() compile again, and improves the test
logic to use our standard CWD support for WASI.

strings (#13526)
* Export invalidFmtErr
To allow consistent use of "invalid format string" compile error
response for badly formatted format strings.
See https://github.com/ziglang/zig/pull/13489#issuecomment-1311759340.
* Replace format compile errors with invalidFmtErr
- Provides more consistent compile errors.
- Gives user info about the type of the badly formated value.
* Rename invalidFmtErr as invalidFmtError
For consistency. Zig seems to use “Error” more often than “Err”.
* std: add invalid format string checks to remaining custom formatters
* pass reference-trace to comp when building build file; fix checkobjectstep

Before this would fail to compile:
```
fn testFn(alloc: std.mem.Allocator, arr: []const u8) !void {
_ = alloc;
_ = arr;
}
test "checkAll" {
var arr = [_]u8{ 1, 2, 3 };
try std.testing.checkAllAllocationFailures(std.testing.allocator, testFn, .{arr[0..]});
}
```
with the error `error: Unexpected type for extra argument at index 0: expected []const u8, found *[3]u8`
By removing this strict equality check, we allow the type checking to be done during the `@field(args, arg_i_str) = @field(extra_args, field.name);` instead, which then allows for things like type coercion to work, but still will give a compile error if the types are incorrect. So, after this change, the above succeeds (because `*[3]u8` can be coerced to `[]const u8`).
The new compile error when providing an incorrect type that can't be coerced looks like this:
```
zig/lib/std/testing.zig:639:35: error: expected type '[]const u8', found '*[3]u32'
@field(args, arg_i_str) = @field(extra_args, field.name);
^
```

(split from NondeterministicMemoryUsage)
Inducing failure but not getting OutOfMemory back is not as much of a problem as never inducing failure when it was expected to be induced, so treating them differently and allowing them to be handled differently by the caller is useful.
For example, the current implementation of `std.HashMapUnmanaged.getOrPutContextAdapted` always tries to grow and then recovers from OutOfMemory by attempting a lookup of an existing key. If this function is used (i.e. from `std.BufMap.putMove`) with `checkAllAllocationFailures`, then we'd have previously triggered `error.NondeterministicMemoryUsage`, but the real cause is that `OutOfMemory` is being recovered from and so the error is being swallowed. The new error allows us to both understand what's happening easier and to catch it and ignore it if we're okay with the code we're testing handling `error.OutOfMemory` without always bubbling it up.

This tight coupling causes problems for various targets, requires
hacky "get args" functionality, and bungles relative file system paths,
making invalid assumptions about the zig-cache directory.
In short, these are not unit tests; these should be standalone tests
instead.

Instead, just return ChildProcess directly. This structure does not
require a stable address, so we can put it on the stack just fine. If
someone wants it on the heap they should do.
const proc = try allocator.create(ChildProcess);
proc.* = ChildProcess.init(args, allocator);

This reverts commit 75c9936737a6ba991d4ef187ddc9d51bc0ad0998, reversing
changes made to 7f13f5cd5f5a518638b15d7225eae2d88ec1efb5.
I don't think `runZigBuild` belongs in std.testing. We already have
`test/standalone/*` for this.
Additionally test names should explain what they are testing rather than
referencing GitHub issue numbers.

This reverts commit 7f13f5cd5f5a518638b15d7225eae2d88ec1efb5.
I'd like to review this one before it goes in. This is an awfully
specific API that I don't think belongs in std.testing. Also I don't
want any code snippets in doc strings. We have doctests for that.

std: explicitly handle error.UnexpectedExitCode in build_runner
|
|
* remove need for manual string concatenation for building binaries in test blocks
* include small program snippet to show how to get binary path with subslicing
|
|
* unify the logic for exporting math functions from compiler-rt,
with the appropriate suffixes and prefixes.
- add all missing f128 and f80 exports. Functions with missing
implementations call other functions and have TODO comments.
- also add f16 functions
* move math functions from freestanding libc to compiler-rt (#7265)
* enable all the f128 and f80 code in the stage2 compiler and behavior
tests (#11161).
* update std lib to use builtins rather than `std.math`.

Two major changes here:
1. We store the CWD as a simple `[]const u8` and lookup Preopens for
every absolute or CWD-referenced file operation, based on the
Preopen with the longest match (i.e. most specific path)
2. Preorders are normalized to POSIX absolute paths at init time.
Behavior depends on the "cwd_root" parameter of `initPreopensWasi`:
`cwd_root` is used for any Preopens that start with "."
For example:
"./foo/bar" - inits to -> "{cwd_root}/foo/bar"
"foo/bar" - inits to -> "/foo/bar"
"/foo/bar" - inits to -> "/foo/bar"
`cwd_root` must be an absolute path.
Using "/" as `cwd_root` gives behavior similar to wasi-libc.

Adds a function that allows checking for memory leaks (and other problems) by taking advantage of the FailingAllocator and inducing failure at every allocation point within the provided `test_fn` (based on the strategy employed in the Zig parser tests, which can now use this function).

continuation of #11093 to simplify testing IPC
* use cases
- get path to temporary directory
- get the test arguments inside test block for reusage
- build executables from text within test blocks, ie to test IPC
* missing conventions
- how to name and debug test cases
- where do simple+repititve build commands for testing belong
|
|
* make it always return a fully qualified name. stage1 is inconsistent
about this.
* AstGen: fix anon_name_strategy to correctly be `func` when anon type
creation happens in the operand of the return expression.
* Sema: implement type names for the "function" naming strategy.
* Put "enum", "union", "opaque", or "struct" in place of "anon" when
creating respective anonymous Decl names.
* std.testing: add `expectStringStartsWith`. Didn't end up using it
after all.
Also this enables the real test runner for stage2 LLVM backend (sans
wasm32) since it works now.

At some point we changed these functions to return errors instead of
aborting.

AIR:
* `array_elem_val` is now allowed to be used with a vector as the array
type.
* New instructions: splat, vector_init
AstGen:
* The splat ZIR instruction uses coerced_ty for the ResultLoc, avoiding
an unnecessary `as` instruction, since the coercion will be performed
in Sema.
* Builtins that accept vectors now ignore the type parameter. Comment
from this commit reproduced here:
The accepted proposal #6835 tells us to remove the type parameter from
these builtins. To stay source-compatible with stage1, we still observe
the parameter here, but we do not encode it into the ZIR. To implement
this proposal in stage2, only AstGen code will need to be changed.
Sema:
* `clz` and `ctz` ZIR instructions are now handled by the same function
which accept AIR tag and comptime eval function pointer to
differentiate.
* `@typeInfo` for vectors is implemented.
* `@splat` is implemented. It takes advantage of `Value.Tag.repeated` 😎
* `elemValue` is implemented for vectors, when the index is a scalar.
Handling a vector index is still TODO.
* Element-wise coercion is implemented for vectors. It could probably
be optimized a bit, but it is at least complete & correct.
* `Type.intInfo` supports vectors, returning int info for the element.
* `Value.ctz` initial implementation. Needs work.
* `Value.eql` is implemented for arrays and vectors.
LLVM backend:
* Implement vector support when lowering `array_elem_val`.
* Implement vector support when lowering `ctz` and `clz`.
* Implement `splat` and `vector_init`.
