Before this fix, passing an undefined union value to `Sema.switchCond`
returned an undefined value of the union type, not the tag type, since
`Value.unionTag` forwards undefined values unchanged.
This leads us into the `.Union` branch in `Sema.zirSwitchBlock` which is
unreachable, now we take the `.Enum` branch instead.
The generic call `S.foo()` was evaluated with the
capture scope of the owner decl (i.e the `test` block), when it should
use the capture scope of the function declaration.
This commit eliminates the `dbg_block_{begin,end}` instructions from
both ZIR and AIR. Instead, lexical scoping of `dbg_var_{ptr,val}`
instructions is decided based on the AIR block they exist within. This
is a much more robust system, and also results in a huge drop in ZIR
bytes - around 7% for Sema.zig.
This required some enhancements to Sema to prevent elision of blocks
when they are required for debug variable scoping. This can be observed
by looking at the AIR for the following simple test program with and
without `-fstrip`:
```zig
export fn f() void {
{
var a: u32 = 0;
_ = &a;
}
{
var a: u32 = 0;
_ = &a;
}
}
```
When `-fstrip` is passed, no AIR blocks are generated. When `-fno-strip`
is passed, the ZIR blocks are lowered to true AIR blocks to give correct
lexical scoping to the debug vars.
The changes here incidentally reolve #19060. A corresponding behavior
test has been added.
Resolves: #19060
* 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
Windows paths now use WTF-16 <-> WTF-8 conversion everywhere, which is lossless. Previously, conversion of ill-formed UTF-16 paths would either fail or invoke illegal behavior.
WASI paths must be valid UTF-8, and the relevant function calls have been updated to handle the possibility of failure due to paths not being encoded/encodable as valid UTF-8.

I originally removed these in 402f967ed5339fa3d828b7fe1d57cdb5bf38dbf2.
I allowed them to be added back in #15299 because they were smuggled in
alongside a bug fix, however, I wasn't kidding when I said that I wanted
to take the design of std.http in a different direction than using this
data structure.
Instead, some headers are provided via explicit field names populated
while parsing the HTTP request/response, and some are provided via
new fields that support passing extra, arbitrary headers.
This resulted in simplification of logic in many places, as well as
elimination of the possibility of failure in many places. There is
less deinitialization code happening now.
Furthermore, it made it no longer necessary to clone the headers data
structure in order to handle redirects.
http_proxy and https_proxy fields are now pointers since it is common
for them to be unpopulated.
loadDefaultProxies is changed into initDefaultProxies to communicate
that it does not actually load anything from disk or from the network.
The function now is leaky; the API user must pass an already
instantiated arena allocator. Removes the need to deinitialize proxies.
Before, proxies stored arbitrary sets of headers. Now they only store
the authorization value.
Removed the duplicated code between https_proxy and http_proxy. Finally,
parsing failures of the environment variables result in errors being
emitted rather than silently ignoring the proxy.
error.CompressionNotSupported is renamed to
error.CompressionUnsupported, matching the naming convention from all
the other errors in the same set.
Removed documentation comments that were redundant with field and type
names.
Disabling zstd decompression in the server for now; see #18937.
I found some apparently dead code in src/Package/Fetch/git.zig. I want
to check with Ian about this.
I discovered that test/standalone/http.zig is dead code, it is only
being compiled but not being run. Furthermore it hangs at the end if you
run it manually. The previous commits in this branch were written under
the assumption that this test was being run with
`zig build test-standalone`.
