This adds the atomic opcodes for the Threads proposal to the
WebAssembly specification: https://github.com/WebAssembly/threads
PrefixedOpcode has been renamed to MiscOpcode as there's multiple
types of prefixed opcodes. This naming is similar to other tools
such as LLVM. As we now use the 0xFE prefix, we moved the
function_index MIR instruction as it was occupying the same value.
This commit includes renaming all related opcodes.
Rather than adding the flags "on-demand" during limits writing,
we now properly parse them and store the flags within the limits
itself. This also allows us to store whether we're using shared-
memory or not. Only when the correct flag is set will we set the
max within `Limits` or else we will leave it `undefined`.
It seems like the original code of setsockopt is not effective because
i catch the EINVAL branch when uncomment this code, it should call
setsockopt before the bind call.
This should fix issue #14900.

This is useful for tests that want to `execve` zig directly. The string
is already null-terminated, so this will just expose it as such,
removing an extra allocation from the test.
Will be used in #14462
This is useful for creating byte buffers of actually-different-things.
Copied the argument order from `Allocator.alignedAlloc`
I noted that `ArrayListAligned` is going out of it's way to not set the
alignment at comptime when it is not specified. However, I was not able
to do that the same way here, and good people on IRC, @ifreund in
particular (thanks!) assured me that
[N]T align(@alignOf(T))
is equivalent to
[N]T
Move to c/darwin.zig as they really are libSystem/libc imports/wrappers.
As an added bonus, get rid of the nasty `usingnamespace`s which are now
unneeded.
Finally, add `os.ptrace` but currently only implemented on darwin.
Previously this code asserted that a fifo's readable length was greater
than or equal to the length of its readable slice, which was an invalid
assertion.
This code avoids making that assumption.
This error means that there *was* a file in this location on the file
system, but it was deleted. However, the OS is not finished with the
deletion operation, and so this CreateFile call has failed. There is not
really a sane way to handle this other than retrying the creation after
the OS finishes the deletion.
The error was caught and created a Step failure rather than bubbling up
so that the interpreter logic could handle it. Fixes hundreds of test
failures on Windows.
There are no dir components, so you would think that this was
unreachable, however we have observed on macOS two processes racing
to do openat() with O_CREAT manifest in ENOENT.
The OS layer expects pointer addresses to be inside the application's
address space even if the length is zero. Meanwhile, in Zig, slices may
have undefined pointer addresses when the length is zero. So this
function now modifies the iov_base fields when the length is zero.
This is a companion commit to b4893eb05565b2cb033c6ed88617d73faf878455.
* Remove some functions that are no longer needed since
EmulateableRunStep is gone.
* Add removeEnvironmentVariable function.
* Support printing environment variables in --verbose mode.
This unit test tested the command line arguments which were passed to
the test runner, which is not really something that unit tests are
supposed to observe.
The proper way to test command line argument parsing is with a
standalone test, where the set of command line arguments being tested
for are also being controlled by the test itself.
std.Build.addTest creates a CompileStep as before, however, this kind of
step no longer actually runs the unit tests. Instead it only compiles
it, and one must additionally create a RunStep from the CompileStep in
order to actually run the tests.
RunStep gains integration with the default test runner, which now
supports the standard --listen=- argument in order to communicate over
stdin and stdout. It also reports test statistics; how many passed,
failed, and leaked, as well as directly associating the relevant stderr
with the particular test name that failed.
This separation of CompileStep and RunStep means that
`CompileStep.Kind.test_exe` is no longer needed, and therefore has been
removed in this commit.
* build runner: show unit test statistics in build summary
* added Step.writeManifest since many steps want to treat it as a
warning and emit the same message if it fails.
* RunStep: fixed error message that prints the failed command printing
the original argv and not the adjusted argv in case an interpreter
was used.
* RunStep: fixed not passing the command line arguments to the
interpreter.
* move src/Server.zig to std.zig.Server so that the default test runner
can use it.
* the simpler test runner function which is used by work-in-progress
backends now no longer prints to stderr, which is necessary in order
for the build runner to not print the stderr as a warning message.
std.zig.system.NativeTargetInfo.getExternalExecutor previously would
incorrectly communicate that wine could be used to run aarch64-windows
binaries on x86_64-linux, and x86_64-windows binaries on aarch64-linux.
Neither of these things are true.
This commit extracts out server code into src/Server.zig and uses it
both in the main CLI as well as `zig objcopy`.
std.Build.ObjCopyStep now adds `--listen=-` to the CLI for `zig objcopy`
and observes the protocol for progress and other kinds of integrations.
This fixes the last two test failures of this branch when I run
`zig build test` locally.
Previously this code used SipHash(1, 3) directly; now that we have the
cache system available in the build system, borrow the same
implementation as is being used everywhere else.
* std.zig.ErrorBundle: support rendering options for whether to include
the reference trace, whether to include the source line, and TTY
configuration.
* build runner: don't print progress in dumb terminals
* std.Build.CompileStep:
- add a way to expect compilation errors via the new `expect_errors`
field. This is an advanced setting that can change the intent of
the CompileStep. If this slice has nonzero length, it means that
the CompileStep exists to check for compile errors and return
*success* if they match, and failure otherwise.
- remove the object format parameter from `checkObject`. The object
format is known based on the CompileStep's target.
- Avoid passing -L and -I flags for nonexistent directories within
search_prefixes. This prevents a warning, that should probably be
upgraded to an error in Zig's CLI parsing code, when the linker
sees an -L directory that does not exist.
* std.Build.Step:
- When spawning the zig compiler process, takes advantage of the new
`std.Progress.Node.setName` API to avoid ticking up a meaningless
number at every progress update.
The OS layer expects pointer addresses to be inside the application's
address space even if the length is zero. Meanwhile, in Zig, slices may
have undefined pointer addresses when the length is zero. So this
function now modifies the iov_base fields when the length is zero.
This is for bypassing the package manager and directly depending on
another package via the build system. For this to work the anonymous
package must be found on the file system relative to the current
package's build.zig.
