and delete deprecated alias std.io

These names aren't matching any formal specification; they're mostly
just ripped from LLVM code. Therefore, we should definitely follow Zig
naming conventions here.
|
|
Most of these changes seem like improvements. The PDB thing had a TODO
saying it used to crash; I anticipate it works now, we'll see what CI
does.
The `std.os.uefi` field renames are a notable breaking change.

This code has the hard-coded goal of supporting the executable's own
debug information and makes design choices along that goal, such as
memory-mapping the inputs, using dl_iterate_phdr, and doing conditional
compilation on the host target.
A more general-purpose implementation of debug information may be able
to share code with this, but there are some fundamental
incompatibilities. For example, the "SelfInfo" implementation wants to
avoid bloating the binary with PDB on POSIX systems, and likewise DWARF
on Windows systems, while a general-purpose implementation needs to
support both PDB and DWARF from the same binary. It might, for example,
inspect the debug information from a cross-compiled binary.
`SourceLocation` now lives at `std.debug.SourceLocation` and is
documented.
Deprecate `std.debug.runtime_safety` because it returns the optimization
mode of the standard library, when the caller probably wants to use the
optimization mode of their own module.
`std.pdb.Pdb` is moved to `std.debug.Pdb`, mirroring the recent
extraction of `std.debug.Dwarf` from `std.dwarf`.
I have no idea why we have both Module (with a Windows-specific
definition) and WindowsModule. I left some passive aggressive doc
comments to express my frustration.

Let's take this breaking change opportunity to fix the style of this
enum.
|
|
Use inline to vastly simplify the exposed API. This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.

Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change

The majority of these are in comments, some in doc comments which might
affect the generated documentation, and a few in parameter names -
nothing that should be breaking, however.

This fixes a bug in std.net caused during the introduction of
meta.assumeSentinel due to the unfortunate semantics of mem.span()
This leaves only 3 remaining uses of meta.assumeSentinel() in the
standard library, each of which could be a simple @ptrCast([*:0]T, foo)
instead. I think this function should likely be removed.

Make sure `ProcSym` includes a single element byte-array which delimits
the start of the symbol's name as part of its definition. This makes
the code more elegant in that accessing the name is equivalent to taking
the address of this one element array.

With this change, it is now possible to safely call
`var di = std.debug.openSelfDebugInfo(gpa)`. Calling then
`di.deinit()` on the object will correctly free all allocated
resources.
Ensure we store the result of `mmap` with correct alignment.

We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.

No functional changes are expected, this patch is only moving some code
in order to slim the huge bowl of spaghetti that is debug.zig.
The amount of memory leaked on error is much less than before but not
zero, some further work is required to smooth the edges of this old part
of the stdlib.

* `comptime const` is redundant
* don't use `extern enum`; specify a tag type.
`extern enum` is only when you need tags to alias. But aliasing tags
is a smell. I will be making a proposal shortly to remove `extern enum`
from the language.
* there is no such thing as `packed enum`.
* instead of `catch |_|`, omit the capture entirely.
* unused function definition with missing parameter name
* using `try` outside of a function or test

also make simple file operations work asynchronously on windows
|
|
|
|
The main goal here is to make the function pointers comptime, so that we
don't have to do the crazy stuff with async function frames.
Since InStream, OutStream, and SeekableStream are already generic
across error sets, it's not really worse to make them generic across the
vtable as well.
See #764 for the open issue acknowledging that using generics for these
abstractions is a design flaw.
See #130 for the efforts to make these abstractions non-generic.
This commit also changes the OutStream API so that `write` returns
number of bytes written, and `writeAll` is the one that loops until the
whole buffer is written.
