Now `main` takes an `init: std.Init` parameter, and this is the only way
to access command line arguments and environment variables.
After a deprecation period, this will close#4524
breaking change to the fuzz testing API; it now passes a type-safe
context parameter to the fuzz function.
libfuzzer is reworked to select inputs from the entire corpus.
I tested that it's roughly as good as it was before in that it can find
the panics in the simple examples, as well as achieve decent coverage on
the tokenizer fuzz test.
however I think the next step here will be figuring out why so many
points of interest are missing from the tokenizer in both Debug and
ReleaseSafe modes.
does not quite close#20803 yet since there are some more important
things to be done, such as opening the previous corpus, continuing
fuzzing after finding bugs, storing the length of the inputs, etc.
std.c.NI was never used in the source, so let's finally use it and make
the function more clear!
This is a breaking change, although a minor one: If you previously passed 0 here
(meaning no flags), then now you have to pass an empty struct (.{}) instead.
Otherwise, you probably used @bitCast() shenanigans here (like
@bitCast(c.NI { .NUMERICHOST = true }) and that will still work, but you can
also get rid of the @bitCast() now!
Zig's copy of the `SYMLINK_{NO,}FOLLOW` constants from wasi-musl was
wrong, as were the `IFIFO` and `IFSOCK` file type flags. Fix these up,
and add comments pointing to exactly where they come from (as the
wasi-musl source has lots of unused, different definitions of these
constants).
Add tests for the Zig convention that WASM preopen 3 is the current
working directory. This is true for WASM with or without libc.
Enable several fs and posix tests that are now passing (not necessarily
because of this change) on wasm targets.
Fixes#20890.
Freelist length accounting in alloc had a negative impact, especially
with the integer type bumped up to u16, so I changed the system to be
based on counting slabs rather than total allocations.
* slab length reduced to 64K
* track freelist length with u8s
* on free(), rotate if freelist length exceeds max_freelist_len
Prevents memory leakage in the scenario where one thread only allocates
and another thread only frees.
