* 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.
* build.zig: introduce `-Dflat` option which makes the installation
match what we want to ship for our download tarballs. This allows
deleting a bunch of shell script logic from the CI.
- for example it puts the executable directly in prefix/zig rather
than prefix/bin/zig and it additionally includes prefix/LICENSE.
* build.zig: by default also install std lib documentation to doc/std/
- this can be disabled by `-Dno-autodocs` similar to how there is
already `-Dno-langref`.
* build.zig: add `std-docs` and `langref` steps which build and install
the std lib autodocs and langref to prefix/doc/std and
prefix/doc/langref.html, respectively.
* std.Build: implement proper handling of `-femit-docs` using the
LazyPath system. This is a breaking change.
- this is a partial implementation of #16351
* frontend: fixed the handling of Autodocs with regards to caching and
putting the artifacts in the proper location to integrate with the
build system.
- closes#15864
* CI: delete the logic for autodocs since it is now handled by build.zig
and is enabled by default.
- in the future we should strive to have nearly all the CI shell
script logic deleted in favor of `zig build` commands.
* CI: pass `-DZIG_NO_LIB=ON`/`-Dno-lib` except for the one command where
we want to actually generate the langref and autodocs. Generating the
langref takes 14 minutes right now (why?!) so we don't want to do that
more times than necessary.
* Autodoc: fixed use of a global variable. It works fine as a local
variable instead.
- note that in the future we will want to make Autodoc run
simultaneously using the job system, but for now the principle of
YAGNI dictates that we don't have an init()/deinit() API and instead
simply call the function that does the things.
* Autodoc: only do it when there are no compile errors
* build.zig: the result of b.option() can be assigned directly in many
cases thanks to the return type being an optional
* std.Build: make the build system aware of the
std.Build.Step.Compile.BuildId type when used as an option.
- remove extraneous newlines in error logs
* simplify caching logic
* simplify hexstring parsing tests and use a doc test
* simplify hashing logic. don't use an optional when the `none` tag
already provides this meaning.
* CLI: fix incorrect linker arg parsing
This commit installs Zig to "build_dir/stage3" during building
so that distros' can easily find binary and use it for testing/etc.
This commit also splits "add_custom_target(stage3 ALL" and command that it invokes,
so that it won't retry it during installation,
as target will be considered not out-of-date.

Following @Luukdegram's comment[1]:

I find myself quite often creating ReleaseSafe builds and putting them
to production for certain experiments:
- Debug info are for stack traces. An ongoing example where those would
help is #14815.
- Safety checks would have saved a couple of mine and @kubkon's hours in
#15098.
This is a breaking change for scripts that make Zig releases -- I will
submit another PR to zig-bootstrap and release-cutter after this is
merged.
Make the test targets use options that match the actual options of
CompileStep. This makes the code more straightforward, and ends up
making fewer tests incorrectly skipped. For example, now the CI runner
on Windows will no longer skip self-hosted x86_64 backend tests.
* Add `omit_pkg_fetching_code` option to test_cases
* Change `omit_pkg_fetching_code` to always `true` for test_cases

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
It is reasonable to pass -Dskip-non-native when unable to run foreign
binaries, however there is no option for being able to run foreign
static binaries but unable to run foreign dynamic binaries. This can
occur when qemu is installed but not cross glibc.
it still writes the output to zig-cache/langref.html but now it does
that explicitly as a legacy step with the intention of having that
removed in the future. It also outputs the langref to the install
prefix.
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.
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.
These were mostly already using the correct build API. I cleaned up the
code a bit and unconditionally disabled LTO for these tests since that
actually tests the intended behavior better.
CLI tests are now ported over to the new std.Build API and thus work
properly with concurrency.
* add `std.Build.addCheckFile` for creating a
`std.Build.CheckFileStep`.
* add `std.Build.makeTempPath`. This function is intended to be called
in the `configure` phase only. It returns an absolute directory path,
which is potentially going to be a source of API breakage in the
future, so keep that in mind when using this function.
* add `std.Build.CheckFileStep.setName`.
* `std.Build.CheckFileStep`: better error message when reading the
input file fails.
* `std.Build.RunStep`: add a `has_side_effects` flag for when you need
to override the autodetection.
* `std.Build.RunStep`: add the ability to obtain a FileSource for the
directory that contains the written files.
* `std.Build.WriteFileStep`: add a way to write bytes to an arbitrary
path - absolute or relative to the package root. Be careful with this
because it updates source files. This should not be used as part of
the normal build process, but as a utility occasionally run by a
developer with intent to modify source files and then commit those
changes to version control. A file added this way is not available
with `getFileSource`.
