I moved part of the compiler that checks environment variables to the
standard library, so it doesn't have access to `build_options.only_c`
anymore, which means some environment variable checks are leaking into
the zig1.wasm build of zig. This logic still makes it return "no
environment variables found" though.
InvalidHandle in OpenError is no longer a possible error on any platform. In the past it was able to be returned in `openOptionsFromFlagsWasi`, but the implementation was changed in 7680c5330c to make it no longer possible.
InvalidHandle in RealPathError was a holdover from before d5312d53a0, which made realpath a compile error on WASI. However, InvalidHandle was also a possible error in the FreeBSD fallback implementation added in 537624734c. This commit changes the FreeBSD fallback implementation to return FileNotFound instead of InvalidHandle which matches how EBADF is handled in all the other `realpath` implementations (including the FreeBSD non-fallback implementation).
Closes#19084
* Support different keep alive defaults with different http versions.
* Fix incorrect usage of `copyBackwards`, which copies in a backwards
direction allowing data to be moved forward in a buffer, not
backwards in a buffer.
- Add default values to the list of comptime-known elements in
`zirValidatePtrArrayInit`
- In `structFieldValueComptime`, only assert `haveFieldInits` if we
enter the`fieldIsComptime` branch (otherwise they are not needed).
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.
Follow up to #19079, which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"
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
