A compilation build step for which the binary is not required could not
be compiled previously. There were 2 issues that caused this:
- The compiler communicated only the results of the emitted binary and
did not properly communicate the result if the binary was not emitted.
This is fixed by communicating the final hash of the artifact path (the
hash of the corresponding /o/<hash> directory) and communicating this
instead of the entire path. This changes the zig build --listen protocol
to communicate hashes instead of paths, and emit_bin_path is accordingly
renamed to emit_digest.
- There was an error related to the default llvm object path when
CacheUse.Whole was selected. I'm not really sure why this didn't manifest
when the binary is also emitted.
This was fixed by improving the path handling related to flush() and
emitLlvmObject().
In general, this commit also improves some of the path handling throughout
the compiler and standard library.

Deprecates std.fs.atomicSymLink and removes the allocator requirement
from the new std.fs.Dir.atomicSymLink. Replaces the two usages of this
within std.
I did not include the TODOs from the original code that were based
off of `switch (err) { ..., else => return err }` not having correct
inference that cases handled in `...` are impossible in the error
union return type because these are not specified in many places but
I can add them back if wanted.
Thank you @squeek502 for help with fixing buffer overflows!

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.

* Add -f(no-)sanitize-coverage-trace-pc-guard CLI flag which defaults to
off. This value lowers to TracePCGuard = true (LLVM backend) and -Xclang
-fsanitize-coverage-trace-pc-guard. These settings are not
automatically included with -ffuzz.
* Add `Build.Step.Compile` flag for sanitize_coverage_trace_pc_guard
with appropriate documentation.
* Add `zig cc` integration for the respective flags.
* Avoid crashing in ELF linker code when -ffuzz -femit-llvm-ir used
together.

`PKG_CONFIG` environment variable is used to override path to
pkg-config executable, for example when it's name is prepended by
target triple for cross-compilation purposes:
```
PKG_CONFIG=/usr/bin/aarch64-unknown-linux-gnu-pkgconf zig build
```

Remove --debug-incremental
This flag is also added to the build system. Importantly, this tells
Compile step whether or not to keep the compiler running between
rebuilds. It defaults off because it is currently crashing
zirUpdateRefs.
|
|
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

main: print the self_exe_path when `findZigLibDirFromSelfExe` fails in all cases

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

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

Adds an `include_paths` field to RcSourceFile that takes a slice of LazyPaths. The paths are resolved and subsequently appended to the -rcflags as `/I <resolved path>`.
This fixes an accidental regression from https://github.com/ziglang/zig/pull/19174. Before that PR, all Win32 resource compilation would inherit the CC flags (via `addCCArgs`), which included things like include directories. After that PR, though, that is no longer the case.
However, this commit intentionally does not restore the previous behavior (inheriting the C include paths). Instead, each .rc file will need to have its include paths specified directly and the include paths only apply to one particular resource script. This allows more fine-grained control and has less potentially surprising behavior (at the cost of some convenience).
Closes #19605

Windows does not support RPATH and only searches for DLLs in a small
number of predetermined paths by default, with one of them being the
directory from which the application loaded.
Installing both executables and DLLs to `bin/` by default helps ensure
that the executable can find any DLL artifacts it has linked to.
DLL import libraries are still installed to `lib/`.
These defaults match CMake's behavior.

This is a partial revert of 105db13536b4dc2affe130cb8d2eee6c97c89bcd.
As we learned from Void Linux packaging, these options are not actually
helpful since the distribution package manager may very well want to
cross-compile the packages that it is building.
So, let's not overcomplicate things. There are already the standard
options: -Dtarget, -Dcpu, and -Ddynamic-linker.
These options are generally provided when the project generates machine
code artifacts, however, there may be a project that does no such thing,
in which case it makes sense for these options to be missing. The Zig
Build System is a general-purpose build system, after all.

This adds the *std.Build owner to LazyPath so that lazy paths returned
from a dependency can be used in the application without friction or
footguns.
closes #19313
|
|
This is a temporary workaround that can be revered if/when 'path'
lazy paths are updated to encode which build root they are relative to.
|
|
Also renames `addHeaders` to `addHeadersDirectory` for clarity.
|
|
Added test coverage for `installLibraryHeaders`
|
|
|
|
|
|
Previously, `Step.Compile.installHeader` and friends would incorrectly
modify the default `install` top-level step, when the intent was for
headers to get bundled with and installed alongside an artifact. This
change set implements the intended behavior.
This carries with it some breaking changes; `installHeader` and
`installConfigHeader` both have new signatures, and
`installHeadersDirectory` and `installHeadersDirectoryOptions` have been
merged into `installHeaders`.

Corresponds to the `-municode` CLI flag

|
|
* make test names contain the fully qualified name
* make test filters match the fully qualified name
* allow multiple test filters, where a test is skipped if it does not
match any of the specified filters

std: make options a struct instance instead of a namespace
|
|
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.

Closes #18628
This commit splits the arguments obtained from pkg-config into two
groups, cflags and libs, and consistently applies the cflags to each
individual module linking the library while applying the libs only once
for each compilation.
|
|
Uses the new `-M[name][=src]` CLI syntax to omit the source when the
module does not have a zig root source file.
Only some kinds of link objects imply that this should happen.

std.Build.Step.Compile: fix link object paths
|

They were being resolved relative to the wrong owner.
closes #18460

This resulted in an error building a transitive module dependency.
