I changed my mind on how the CLI for Zig modules should work. I don't
like that `--mod` takes 2 parameters. Instead let's swing all the way in
the other direction: `-M[name][=src]`
This is shorter (Zig CLI invocations are long enough already), avoids
the double parameter edge case, and supports the concept of omitting the
source file part of the argument, which was already wanted for `-Mstd`.
The legacy way to encode that was `--mod std ''` - awkward!
Undocumented support for `--mod` remains so that this branch does not
need a zig1.wasm update. The next time that file is updated, support for
`--mod` can be dropped.
Importantly, this commit also adds support for modules that do not have
a root zig source file. In such case, it sets root to cwd and
root_src_path to empty string, and only sets have_zcu to true if a
module is provided with a root zig source file.
The deleted lines here are redundant because they happen first thing
inside the function call below.
Additionally, skip hashing the root source file if it is an empty
string. I explored making this field along with `root` optional but
found this to be less messy actually.
This section documented how a buggy feature worked at one point in time
but it's not a description of what is supposed to happen. What is
supposed to happen is simple enough to not warrant any documentation
about it. When a file is imported, all the test decls are supposed to be
queued for analysis.
Also, refAllDecls() is a hack which should not be celebrated or even
mentioned in the language reference.

The code asserted that the range to be replaced is within bounds of
`self.items`.
This is now reflected in the doc comment.
The old, wrong doc comment was copied from the `insert*` fns.
With this assertion holding true, `start + len` is always within the
address space and `start + new_items.len` is, at this point, always
strictly within bounds of `self.items`.
Previously `@as(i64, undefined) +% 1` would produce `@as(@TypeOf(undefined), undefined)` which now gives `@as(i64, undefined)`.
Previously `@as(i64, undefined) +| 1` would hit an assertion which now gives `@as(i64, undefined)`.
These changes enable me to use `GeneralPurposeAllocator` with my "Bring
Your Own OS" package. The previous checks for a freestanding target have
been expanded to `@hasDecl` checks.
- `root.os.heap.page_allocator` is used if it exists.
- `debug.isValidMemory` only calls `os.msync` if it's supported.
Per last paragraph of RFC 8446, Section 5.2, the length of the inner content of an encrypted record must not exceed 2^14 + 1, while that of the whole encrypted record must not exceed 2^14 + 256.
Because creation of a symlink can fail on Windows with an Access Denied
error (https://learn.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/create-symbolic-links)
any tests that need a symbolic link "skip" if they run into this problem.
This change factors out a "setupSymbolicLink()" routine to make this
clearer, a bit tighter, and easier to use in future tests.
I also collapsed the "symlink in parent directory" test into the existing
"Dir.readlink" test, because the latter uses the more comprehensive
testWithAllSupportedPathTypes wrapper.
The test runner uses "." in its output between the test module and the
test name, so quote the leading '.' in these test names to make them
easier to read.
Client for tls was using a function that wasn't declared on the
interface for it. The issue wasn't apparent because net stream
implemented that function.
I changed it to keep the interface promise of what's required to be
compatible with the tls client functionality.
As suggested by @matu3ba, it can be better to use Security Attributes
directly while creating the handle instead of creating the handle then
setting the handle to inherit. Doing so can prevent potentially leaking
to other parallel spawned processes which would inherit the opened `\Device\Null`
handle.
This change also allows windows.OpenFile to handle when bInheritHandle
is set.
Note that we are using the same `saAttr`, but since it's taken as a
pointer to a const in all calls, it's never mutated, and OpenFile never alters it.
This also saves 1 kernel call for setting the handle to inherit.
This commit allows write access to the `\\Device\\Null` Handle.
Without a write access, it's not possible for the child process to write
SdOut to Null. As a requirement `SetHandleInformation` was also changed
to mark the handle as iheritable (by adding it to Flags) by the spawned process.
This allows the child to access the NUL device that was opened.
This also makes the Windows part to behave similarly to `spawnPosix`.
