remove std.fs.Dir.readFileAllocOptions, replace with more flexible API
readFileIntoArrayList
remove std.fs.File.readToEndAllocOptions, replace with more flexible API
readIntoArrayList
update std.fs.File to new reader/writer API
add helper functions to std.io.Reader.Limit
replace std.io.Writer.FileLen with std.io.Reader.Limit
make offset a type rather than u64 so that it can distinguish between
streaming read and positional read
avoid an unnecessary allocation in std.zig.readSourceFileToEndAlloc when
there is a UTF-16 little endian BOM.
fix splat implementation in std.fs.File
update http.Client, with caveats:
* TODO: only 1 underlying write call
* TODO: don't rely on max_buffers_len exceeding the caller
* TODO: handle splat
update net.Stream API. also make it use WSASend on windows
After sending the file, better to return total bytes written. The caller
will decide if they want to do another syscall with the trailers. Maybe
the caller would rather buffer them.
Macos uses the BSD definition of msghdr
All linux architectures share a single msghdr definition. Many
architectures had manually inserted padding fields that were endian
specific and some had fields with different integers. This unifies all
architectures to use a single correct msghdr definition.
The overflow check for safe signed subtraction was using the formula (rhs < 0) == (lhs > result). This logic is flawed and incorrectly reports an overflow when the right-hand side is zero.
For the expression 42 - 0, this check evaluated to (0 < 0) == (42 > 42), which is false == false, resulting in true. This caused the generated SPIR-V to incorrectly branch to an OpUnreachable instruction, preventing the result from being stored.
Fixes#24281.
