Jimmi Holst Christensen a0a2ce92ca std: Do not allocate the result for ChildProcess.init
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);

Andrew Kelley c5e847744c Revert "Merge pull request #11214 from iddev5/ay-build-runner"
This reverts commit 75c9936737, reversing
changes made to 7f13f5cd5f.

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.

Andrew Kelley 3052597a73 Revert "std.testing: add writeZigFile for TmpDir"
This reverts commit 7f13f5cd5f.

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.

Andrew Kelley 41dd2beaac compiler-rt: math functions reorg
* 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`.

Cody Tapscott 7b090df668 stdlib std.os: Improve wasi-libc parity for WASI CWD emulation
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.

iddev5 8d3e7aa5e0 std.testing: add function zigBuild for running zig build runner commands 2022-04-04 18:33:47 +05:30
Ryan Liptak 6d04ab6d5b Add std.testing.checkAllAllocationFailures
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).

Andrew Kelley f3f5a5d05b stage2: improve @typeName
* 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.

Andrew Kelley 93b854eb74 stage2: implement @ctz and @clz including SIMD
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`.

Andrew Kelley d29871977f remove redundant license headers from zig standard library
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.

Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.

Frank Denis b8c019ef49 std/base64: cleanups & support url-safe and other non-padded variants
This makes a few changes to the base64 codecs.

* The padding character is optional. The common "URL-safe" variant, in
particular, is generally not used with padding. This is also the case for
password hashes, so having this will avoid code duplication with bcrypt,
scrypt and other functions.
* The URL-safe variant is added. Instead of having individual constants
for each parameter of each variant, we are now grouping these in a
struct. So, `standard_pad_char` just becomes `standard.pad_char`.
* Types are not `snake_case`'d any more. So, `standard_encoder` becomes
`standard.Encoder`, as it is a type.
* Creating a decoder with ignored characters required the alphabet and
padding. Now, `standard.decoderWithIgnore(<ignored chars>)` returns a
decoder with the standard parameters and the set of ignored chars.
* Whatever applies to `standard.*` obviously also works with `url_safe.*`
* the `calcSize()` interface was inconsistent, taking a length in the
encoder, and a slice in the encoder. Rename the variant that takes a
slice to `calcSizeForSlice()`.
* In the decoder with ignored characters, add `calcSizeUpperBound()`,
which is more useful than the one that takes a slice in order to size
a fixed buffer before we have the data.
* Return `error.InvalidCharacter` when the input actually contains
characters that are neither padding nor part of the alphabet. If we
hit a padding issue (which includes extra bits at the end),
consistently return `error.InvalidPadding`.
* Don't keep the `char_in_alphabet` array permanently in a decoder;
it is only required for sanity checks during initialization.
* Tests are unchanged, but now cover both the standard (padded) and
the url-safe (non-padded) variants.
* Add an error set, rename `OutputTooSmallError` to `NoSpaceLeft`
to match the `hex2bin` equivalent.

Andrew Kelley 013efaf139 std: introduce a thread-local CSPRNG for general use
std.crypto.random

* cross platform, even freestanding
* can't fail. on initialization for some systems requires calling
  os.getrandom(), in which case there are rare but theoretically
  possible errors. The code panics in these cases, however the
  application may choose to override the default seed function and then
  handle the failure another way.
* thread-safe
* supports the full Random interface
* cryptographically secure
* no syscall required to initialize on Linux (AT_RANDOM)
* calls arc4random on systems that support it

`std.crypto.randomBytes` is removed in favor of `std.crypto.random.bytes`.

I moved some of the Random implementations into their own files in the
interest of organization.

stage2 no longer requires passing a RNG; instead it uses this API.
