The majority of these are in comments, some in doc comments which might
affect the generated documentation, and a few in parameter names -
nothing that should be breaking, however.
This is a small change to help when reading failure logs which makes the
"exited with code 1" and similar message include the test name.
Further enhancements could do the following:
* even if one unit test crashes the process, the parent process
continues running the other unit tests
* ability to test for expected panics (#1356)
* timeouts on individual tests
* docs(std.math): elaborate on difference between absCast and absInt
* docs(std.rand.Random.weightedIndex): elaborate on likelihood
I think this makes it easier to understand.
* langref: add small reminder
* docs(std.fs.path.extension): brevity
* docs(std.bit_set.StaticBitSet): mention the specific types
* std.debug.TTY: explain what purpose this struct serves
This should also make it clearer that this struct is not supposed to provide unrelated terminal manipulation functionality such as setting the cursor position or something because terminals are complicated and we should keep this struct simple and focused on debugging.
* langref(package listing): brevity
* langref: explain what exactly `threadlocal` causes to happen
* std.array_list: link between swapRemove and orderedRemove
Maybe this can serve as a TLDR and make it easier to decide.
* PrefetchOptions.locality: clarify docs that this is a range
This confused me previously and I thought I can only use either 0 or 3.
* fix typos and more
* std.builtin.CallingConvention: document some CCs
* langref: explain possibly cryptic names
I think it helps knowing what exactly these acronyms (@clz and @ctz) and
abbreviations (@popCount) mean.
* variadic function error: add missing preposition
* std.fmt.format docs: nicely hyphenate
* help menu: say what to optimize for
I think this is slightly more specific than just calling it
"optimizations". These are speed optimizations. I used the word
"performance" here.
* CompileStep: Avoid calling producesPdbFile() to determine whether the
option should be respected. If the user asks for it, put it on the
command line and let the Zig CLI deal with it appropriately.
* Make the namespace of `std.dwarf.Format.dwarf32` no longer have a
redundant "dwarf" in it.
* Add `zig cc` integration for `-gdwarf32` and `-gdwarf64`.
* Toss in a bonus bug fix for `-gdwarf-2`, `-gdwarf-3`, etc.
* Avoid using default init values for struct fields unnecessarily.
* Add missing cache hash addition for the new option.
This commit enables producing 64-bit DWARF format for Zig executables
that are produced through the LLVM backend. This is achieved by exposing
both command-line flags and CompileStep flags. The production of the
64-bit format only affects binaries that use the DWARF format and it is
disabled on MacOS due to it being problematic. This commit, despite
generating the interface for the Zig user to be able to tell the compile
which format is wanted, is just implemented for the LLVM backend, so
clang and the self-hosted backends will need this to be implemented in a
future commit.
This is an effort to work around #7962, since the emission of the 64-bit
format automatically produces 64-bit relocations. Further investigation
will be needed to make DWARF 32-bit format to emit bigger relocations
when needed and not make the linker angry.
This fixes `.INVAL => unreachable` being triggered by the cache system
on macOS when multiple processes race to create the same compilation.
The problem is that when two processes race to create a file, it
sometimes returns ENOENT even though that error code is nonsensical for
this situation.
Commit 2b0929929d purportedly solved this,
but it did not open the file with write permissions, leading to the
EINVAL panic later on. This commit remedies the situation by introducing
a loop and simply retrying when the ENOENT occurs.
The CI now runs C backend tests in addition to compiling them. It uses
-std=c99 -pedantic -Werror in order to catch non-conformant C code.
This necessitated disabling a test case that caused a C compile error,
in addition to disabling a handful of warnings that are already being
triggered by Zig's C backend output for the behavior tests.
The upshot is that I was able to, very cleanly, integrate the C backend
tests into the build system, so that it communicates via the test runner
protocol along with all the other behavior tests.
reverts regression introduced in

The commit correctly removed dest_builder from InstallArtifactStep, but
the change to installLibraryHeaders was incorrect since it affected
different steps than that one.
* remove setName, setFilter, and setTestRunner. Please set these
options directly when creating the CompileStep.
* removed unused field
* remove computeOutFileNames and inline the logic, making clear the
goal of avoiding state mutations after the build step is created.
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
This was used to ensure that an artifact would only be installed once,
but this is not only unnecessary, but actively harmful, in the face of
dependencies.
see #15079
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.
* use the same hash function as the rest of the steps
* fix race condition due to a macOS oddity.
* fix race condition due to file truncation (rename into place instead)
* integrate with marking Step.result_cached. check if the file already
exists with fs.access before doing anything else.
* use a directory so that the file basename can be "options.zig"
instead of a hash digest.
* better error reporting in case of file system failures.
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.
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.
* Remove some functions that are no longer needed since
EmulateableRunStep is gone.
* Add removeEnvironmentVariable function.
* Support printing environment variables in --verbose mode.
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.
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.
* 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.
