These functions are problematic in light of dependencies because they
run and install, respectively, for the *owner* package rather than for
the *user* package. By removing these functions, the build script is
forced to provide the *Build object to associate the new step with,
making everything less surprising.
Unfortunately, this is a widely breaking change.
see #15079
Latest macOS 13.3 rolled out LLVM 15 and thus the way `nullptr_t` is
defined within the `libc++`:

This seems to require including `/usr/include` with `-isystem` directive
rather than `-I`. Otherwise we get clang miscompilation issues due to
missing `nullptr_t` declaration.
Also clean up parsing of linker args - reuse `ArgsIterator`.
In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.
MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.
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.
Instead of using `zig test` to build a special version of the compiler
that runs all the test-cases, the zig build system is now used as much
as possible - all with the basic steps found in the standard library.
For incremental compilation tests (the ones that look like foo.0.zig,
foo.1.zig, foo.2.zig, etc.), a special version of the compiler is
compiled into a utility executable called "check-case" which checks
exactly one sequence of incremental updates in an independent
subprocess. Previously, all incremental and non-incremental test cases
were done in the same test runner process.
The compile error checking code is now simpler, but also a bit
rudimentary, and so it additionally makes sure that the actual compile
errors do not include *extra* messages, and it makes sure that the
actual compile errors output in the same order as expected. It is also
based on the "ends-with" property of each line rather than the previous
logic, which frankly I didn't want to touch with a ten-meter pole. The
compile error test cases have been updated to pass in light of these
differences.
Previously, 'error' mode with 0 compile errors was used to shoehorn in a
different kind of test-case - one that only checks if a piece of code
compiles without errors. Now there is a 'compile' mode of test-cases,
and 'error' must be only used when there are greater than 0 errors.
link test cases are updated to omit the target object format argument
when calling checkObject since that is no longer needed.
The test/stage2 directory is removed; the 2 files within are moved to be
directly in the test/ directory.
I disagree with this behavior and will be reverting the changes
corresponding to this test case.
Also this test case unnecessarily uses a .c file when a .zig file would
be preferred, and has a problematic dependency on the install step,
preventing this test case from playing nicely with the cache.
It's simpler and it takes advantage of
`std.Build.addAnonymousDependency`, which has a number of benefits,
including concurrenc and preventing extra zig-cache and zig-out
directories being created.
4 tests are ported over as an example.
* Eliminate all uses of `std.debug.print` in make() functions, instead
properly using the step failure reporting mechanism.
* Introduce the concept of skipped build steps. These do not cause the
build to fail, and they do allow their dependants to run.
* RunStep gains a new flag, `skip_foreign_checks` which causes the
RunStep to be skipped if stdio mode is `check` and the binary cannot
be executed due to it being a foreign executable.
- RunStep is improved to automatically use known interpreters to
execute binaries if possible (integrating with flags such as
-fqemu and -fwasmtime). It only does this after attempting a native
execution and receiving a "exec file format" error.
- Update RunStep to use an ArrayList for the checks rather than this
ad-hoc reallocation/copying mechanism.
- `expectStdOutEqual` now also implicitly adds an exit_code==0 check
if there is not already an expected termination. This matches
previously expected behavior from older API and can be overridden by
directly setting the checks array.
* Add `dest_sub_path` to `InstallArtifactStep` which allows choosing an
arbitrary subdirectory relative to the prefix, as well as overriding
the basename.
- Delete the custom InstallWithRename step that I found deep in the
test/ directory.
* WriteFileStep will now update its step display name after the first
file is added.
* Add missing stdout checks to various standalone test case build
scripts.
* Step.init() now takes an options struct
* Step.init() now captures a small stack trace and stores it in the
Step so that it can be accessed when printing user-friendly debugging
information, including the lines of code that created the step in
question.
Changes only pertain arm64 as for x86_64 turns out we are
missing one additional feature which is synthesising unwind info
from only eh frame records, or at least this is what it looks like
when I analysed the output of Apple's ld.
When outputting the names section, we should output the actual symbol
name rather than the import name. This makes sure that symbols with
an explicit name set have the correct name but retain the import name
too.
We also now correctly mangle the name of an extern function with an
explicit library name. This ensures that functions that have a
different library name, but the same import/function name, can be
resolved correctly with other modules and don't resolve to the
same symbol.
Adds a linker test case for each possible export case. This means
one where no exports are done (i.e. no flags set), when the -dynamic
flag is set, and finally when --export=<value> flag(s) are set.
