- more support for linux, android, freebsd, netbsd, openbsd, dragonfly
- centralize musl utils; musl logic is no longer intertwined with csu
- fix musl compilation to build crti/crtn for full archs list
- fix openbsd to support `zig build-lib -dynamic`
- initial dragonfly linking success (with a warning)
ancillary:
- fix emutls (openbsd) tests to use `try`
When WSASocketW gets WSANOTINITIALISED, now it will lock a mutex to
safely call WSAStartup and then try again one time.
This implementation:
* Does not use recursion
* Contains a detailed doc comment explaining why things are how they are
* Is careful about which errors are surfaced in the respective error
sets. `std.os.socket` intentionally does not have "not initialised"
as one of the possible errors.
This matches the behaviour of other languages and leaves us
the ability to create actual static Wasm archives with
```
zig build-lib -static some.zig
```
which can then be combined with other Wasm object files and linked
into either a Wasm lib or executable using `wasm-ld`.
Update langref to reflect the fact we now ship WASI libc.
The atfork handler is executed even when fork()-ing threads that have
never initialized their local csprng. Handle this case gracefully
instead of raising a runtime error.
Fixes#8841
Some libc implementations (glib) deduplicate identical hooks, others
(musl, macos) do not and blindly append them to an internal list.
Ensure there's only a single call to pthread_atfork to prevent unbounded
memory use when lots of threads/forks are used.
Now that `@import` of a non-existent file name is a compile error, the
Zig installation needs to include files that end with test.zig. However
we still want to avoid bloat in the installation size, so we blank them
out instead of omitting them entirely.
Now AstGen of the full standard library can complete successfully on a
Zig installation rather than erroring out with file not found.
A previous commit from this branch incorrectly changed the usage of
`comptime` keyword, and broke the std lib tests. This commit adds
`comptime` to a few function calls, correcting the behavior.
Conflicts:
* src/codegen/spirv.zig
* src/link/SpirV.zig
We're going to want to improve the stage2 test harness to print
the source file name when a compile error occurs otherwise std lib
contributors are going to see some confusing CI failures when they cause
stage2 AstGen compile errors.
Let mmap allocate a block of memory that's wide enough to use with
MADV_WIPEONFORK, madvise granularity is the current system page size
(using a static buffer of mem.page_size bytes would be wrong, that's the
minimum page size).
As a result, we don't zero some random chunk of memory every time we
fork the process.
Fixes#7609
