* new .zig-cache subdirectory: 'v'
- stores coverage information with filename of hash of PCs that want
coverage. This hash is a hex encoding of the 64-bit coverage ID.
* build runner
* fixed bug in file system inputs when a compile step has an
overridden zig_lib_dir field set.
* set some std lib options optimized for the build runner
- no side channel mitigations
- no Transport Layer Security
- no crypto fork safety
* add a --port CLI arg for choosing the port the fuzzing web interface
listens on. it defaults to choosing a random open port.
* introduce a web server, and serve a basic single page application
- shares wasm code with autodocs
- assets are created live on request, for convenient development
experience. main.wasm is properly cached if nothing changes.
- sources.tar comes from file system inputs (introduced with the
`--watch` feature)
* receives coverage ID from test runner and sends it on a thread-safe
queue to the WebServer.
* test runner
- takes a zig cache directory argument now, for where to put coverage
information.
- sends coverage ID to parent process
* fuzzer
- puts its logs (in debug mode) in .zig-cache/tmp/libfuzzer.log
- computes coverage_id and makes it available with
`fuzzer_coverage_id` exported function.
- the memory-mapped coverage file is now namespaced by the coverage id
in hex encoding, in `.zig-cache/v`
* tokenizer
- add a fuzz test to check that several properties are upheld

The flag makes compiler_rt and libfuzzer be in debug mode.
Also:
* fuzzer: override debug logs and disable debug logs for frequently
called functions
* std.Build.Fuzz: fix bug of rerunning the old unit test binary
* report errors from rebuilding the unit tests better
* link.Elf: additionally add tsan lib and fuzzer lib to the hash

This flag makes the build runner rebuild unit tests after the pipeline
finishes, if it finds any unit tests.
I did not make this integrate with file system watching yet.
The test runner is updated to detect which tests are fuzz tests.
Run step is updated to track which test indexes are fuzz tests.

closes #17609
|
|
converts an unsigned integer into an array
|
|
Changes the `make` function signature to take an options struct, which
additionally includes `watch: bool`. I intentionally am not exposing
this information to configure phase logic.
Also adds global zig cache to the compiler cache prefixes.
Closes #20600

The docs for setting stdio to "inherit" say:
It also means that this step will obtain a global lock to prevent other
steps from running in the meantime.
The implementation of this lock was missing but is now provided by this
commit.
closes #20119

Introduces `disable_zig_progress` which prevents the build runner from
assigning the child process a progress node.
This is needed for the empty_env test which requires the environment to
be completely empty.

fixes #19938

This allows running commands that take an output directory argument. The
main thing that was needed for this feature was generated file subpaths,
to allow access to the files in a generated directory. Additionally, a
minor change was required to so that the correct directory is created
for output directory args.
|

* `doc/langref` formatting
* upgrade `.{ .path = "..." }` to `b.path("...")`
* avoid using arguments named `self`
* make `Build.Step.Id` usage more consistent
* add `Build.pathResolve`
* use `pathJoin` and `pathResolve` everywhere
* make sure `Build.LazyPath.getPath2` returns an absolute path
|
|
This replaces `extra_file_dependencies` with support for lazy paths.
Also assert output file basenames are not empty, avoid improper use of
field default values, ensure stored strings are duplicated, and
prefer `ArrayListUnmanaged` to discourage misuse of direct field access
which wouldn't add step dependencies.

writeFile was deprecated in favor of writeFile2 in f645022d16361865e24582d28f1e62312fbc73bb. This commit renames writeFile2 to writeFile and makes writeFile2 a compile error.

Someone on IRC got these functions mixed up, and it sure would have been
helpful to have these docs in the first place, eh?
|

Before this fix, the stderr FIFO was advanced by the length
of the trimmed message, thus the next error log contained
the tail of that message.

std: make options a struct instance instead of a namespace
|
|
On second thought, let's keep a bunch of these flags how they already
were.
Partial revert of the previous commit.
|
|
This also makes a long-overdue change of extracting common state from
Build into a shared Graph object.
Getting the semantics right for these flags turned out to be quite
tricky. In the end it works like this:
* The override only happens when the target is fully native, with no
additional query parameters, such as versions or CPU features added.
* The override affects the resolved Target but leaves the original Query
unmodified.
* The "is native?" detection logic operates on the original, unmodified
query. This makes it possible to provide invalid host target
information, causing confusing errors to occur. Don't do that.
There are some minor breaking changes to std.Build API such as the fact
that `b.zig_exe` is now moved to `b.graph.zig_exe`, as well as a handful
of other similar flags.

|
* Specifically recognize stderr as a different concept than an error
message in Step results.
* Display it differently when only stderr occurs but the build proceeds
successfully.

std.Build.Step.Run: fix depfile support
|
|
|
|
This change is seemingly insignificant but I actually agonized over this
for three days. Some other things I considered:
* (status quo in master branch) make Compile step creation functions
accept a Target.Query and delete the ResolvedTarget struct.
- downside: redundantly resolve target queries many times
* same as before but additionally add a hash map to cache target query
resolutions.
- downside: now there is a hash map that doesn't actually need to
exist, just to make the API more ergonomic.
* add is_native_os and is_native_abi fields to std.Target and use it
directly as the result of resolving a target query.
- downside: they really don't belong there. They would be available
as comptime booleans via `@import("builtin")` but they should not
be exposed that way.
With this change the downsides are:
* the option name of addExecutable and friends is `target` instead of
`resolved_target` matching the type name.
- upside: this does not break compatibility with existing build
scripts
* you likely end up seeing `target.result.cpu.arch` rather than
`target.cpu.arch`.
- upside: this is an improvement over `target.target.cpu.arch` which
it was before this commit.
- downside: `b.host.target` is now `b.host.result`.

Previously this relied on recursion; now it relies on the recursive
iteration which is better, but means the recursive call needs to be
deleted.

Caused by problems with transitive dependencies
|
|
Introduce the concept of "target query" and "resolved target". A target
query is what the user specifies, with some things left to default. A
resolved target has the default things discovered and populated.
In the future, std.zig.CrossTarget will be rename to std.Target.Query.
Introduces `std.Build.resolveTargetQuery` to get from one to the other.
The concept of `main_mod_path` is gone, no longer supported. You have to
put the root source file at the module root now.
* remove deprecated API
* update build.zig for the breaking API changes in this branch
* move std.Build.Step.Compile.BuildId to std.zig.BuildId
* add more options to std.Build.ExecutableOptions, std.Build.ObjectOptions,
std.Build.SharedLibraryOptions, std.Build.StaticLibraryOptions, and
std.Build.TestOptions.
* remove `std.Build.constructCMacro`. There is no use for this API.
* deprecate `std.Build.Step.Compile.defineCMacro`. Instead,
`std.Build.Module.addCMacro` is provided.
- remove `std.Build.Step.Compile.defineCMacroRaw`.
* deprecate `std.Build.Step.Compile.linkFrameworkNeeded`
- use `std.Build.Module.linkFramework`
* deprecate `std.Build.Step.Compile.linkFrameworkWeak`
- use `std.Build.Module.linkFramework`
* move more logic into `std.Build.Module`
* allow `target` and `optimize` to be `null` when creating a Module.
Along with other fields, those unspecified options will be inherited
from parent `Module` when inserted into an import table.
* the `target` field of `addExecutable` is now required. pass `b.host`
to get the host target.

This moves many settings from `std.Build.Step.Compile` and into
`std.Build.Module`, and then makes them transitive.
In other words, it adds support for exposing Zig modules in packages,
which are configured in various ways, such as depending on other link
objects, include paths, or even a different optimization mode.
Now, transitive dependencies will be included in the compilation, so you
can, for example, make a Zig module depend on some C source code, and
expose that Zig module in a package.
Currently, the compiler frontend autogenerates only one
`@import("builtin")` module for the entire compilation, however, a
future enhancement will be to make it honor the differences in modules,
so that modules can be compiled with different optimization modes, code
model, valgrind integration, or even target CPU feature set.

Justification: exec, execv etc are unix concepts and portable version
should be called differently.
Do no touch non-Zig code. Adjust error names as well, if associated.
Closes #5853.

Until now, we would pass `candidate: NativeTargetInfo` which creates
a copy of the `NativeTargetInfo.DynamicLinker` buffer. We would then
return this buffer in `bad_dl: []const u8` which would goes out-of-scope
the moment we leave this function frame yielding garbage. To fix this,
we just need to remember to pass by const-pointer
`candidate: *const NativeTargetInfo`.

The callsites of getPath rely on the result being absolute so that they
can pass the path to a child process with the cwd set to the build root.

* introduce LazyPath.cwd_relative variant and use it for --zig-lib-dir. closes #12685
* move overrideZigLibDir and setMainPkgPath to options fields set once
and then never mutated.
* avoid introducing Build/util.zig
* use doc comments for deprecation notices so that they show up in
generated documentation.
* introduce InstallArtifact.Options, accept it as a parameter to
addInstallArtifact, and move override_dest_dir into it. Instead of
configuring the installation via Compile step, configure the
installation via the InstallArtifact step. In retrospect this is
obvious.
* remove calls to pushInstalledFile in InstallArtifact. See #14943
* rewrite InstallArtifact to not incorrectly observe whether a Compile
step has any generated outputs. InstallArtifact is meant to trigger
output generation.
* fix child process evaluation code handling of `-fno-emit-bin`.
* don't store out_h_filename, out_ll_filename, etc., pointlessly. these
are all just simple extensions appended to the root name.
* make emit_directory optional. It's possible to have nothing outputted,
for example, if you're just type-checking.
* avoid passing -femit-foo/-fno-emit-foo when it is the default
* rename ConfigHeader.getTemplate to getOutput
* deprecate addOptionArtifact
* update the random number seed of Options step caching.
* avoid using `inline for` pointlessly
* avoid using `override_Dest_dir` pointlessly
* avoid emitting an executable pointlessly in test cases
Removes forceBuild and forceEmit. Let's consider these additions separately.
Nearly all of the usage sites were suspicious.
