- ILSEQ -> error.BadPathName
- implement dirStatPath for WASI

before, the max length of the host name depended on the target.

There is no straightforward way for the Zig team to access the Solaris system
headers; to do this, one has to create an Oracle account, accept their EULA to
download the installer ISO, and finally install it on a machine or VM. We do not
have to jump through hoops like this for any other OS that we support, and no
one on the team has expressed willingness to do it.
As a result, we cannot audit any Solaris contributions to std.c or other
similarly sensitive parts of the standard library. The best we would be able to
do is assume that Solaris and illumos are 100% compatible with no way to verify
that assumption. But at that point, the solaris and illumos OS tags would be
functionally identical anyway.
For Solaris especially, any contributions that involve APIs introduced after the
OS was made closed-source would also be inherently more risky than equivalent
contributions for other proprietary OSs due to the case of Google LLC v. Oracle
America, Inc., wherein Oracle clearly demonstrated its willingness to pursue
legal action against entities that merely copy API declarations.
Finally, Oracle laid off most of the Solaris team in 2017; the OS has been in
maintenance mode since, presumably to be retired completely sometime in the 2030s.
For these reasons, this commit removes all Oracle Solaris support.
Anyone who still wishes to use Zig on Solaris can try their luck by simply using
illumos instead of solaris in target triples - chances are it'll work. But there
will be no effort from the Zig team to support this use case; we recommend that
people move to illumos instead.

added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string

We now require FreeBSD 13.4+.

This PR consistently maps .ACCES into AccessDenied and .PERM into
PermissionDenied. AccessDenied is returned if the file mode bit
(user/group/other rwx bits) disallow access (errno was `EACCES`).
PermissionDenied is returned if something else denies access (errno was
`EPERM`) (immutable bit, SELinux, capabilities, etc). This somewhat
subtle distinction is a POSIX thing.
Most of the change is updating std.posix Error Sets to contain both
errors, and then propagating the pair up through caller Error Sets.
Fixes #16782

Not nearly the entire downstream patchset but these are completely
uncontroversial and known to work.

It is now composed of these main sections:
* Declarations that are shared among all operating systems.
* Declarations that have the same name, but different type signatures
depending on the operating system. Often multiple operating systems
share the same type signatures however.
* Declarations that are specific to a single operating system.
- These are imported one per line so you can see where they come from,
protected by a comptime block to prevent accessing the wrong one.
Closes #19352 by changing the convention to making types `void` and
functions `{}`, so that it becomes possible to update `@hasDecl` sites
to use `@TypeOf(f) != void` or `T != void`. Happily, this ended up
removing some duplicate logic and update some bitrotted feature
detection checks.
A handful of types have been modified to gain namespacing and type
safety. This is a breaking change.
Oh, and the last usage of `usingnamespace` site is eliminated.

Instead of calling the dynamically loaded kernel32.GetLastError, we can extract it from the TEB.
As shown by [Wine](https://github.com/wine-mirror/wine/blob/34b1606019982b71818780bc84b76460f650af31/include/winternl.h#L439), the last error lives at offset 0x34 of the TEB in 32-bit Windows and at offset 0x68 in 64-bit Windows.

Deprecated aliases that are now compile errors:
- `std.fs.MAX_PATH_BYTES` (renamed to `std.fs.max_path_bytes`)
- `std.mem.tokenize` (split into `tokenizeAny`, `tokenizeSequence`, `tokenizeScalar`)
- `std.mem.split` (split into `splitSequence`, `splitAny`, `splitScalar`)
- `std.mem.splitBackwards` (split into `splitBackwardsSequence`, `splitBackwardsAny`, `splitBackwardsScalar`)
- `std.unicode`
+ `utf16leToUtf8Alloc`, `utf16leToUtf8AllocZ`, `utf16leToUtf8`, `fmtUtf16le` (all renamed to have capitalized `Le`)
+ `utf8ToUtf16LeWithNull` (renamed to `utf8ToUtf16LeAllocZ`)
- `std.zig.CrossTarget` (moved to `std.Target.Query`)
Deprecated `lib/std/std.zig` decls were deleted instead of made a `@compileError` because the `refAllDecls` in the test block would trigger the `@compileError`. The deleted top-level `std` namespaces are:
- `std.rand` (renamed to `std.Random`)
- `std.TailQueue` (renamed to `std.DoublyLinkedList`)
- `std.ChildProcess` (renamed/moved to `std.process.Child`)
This is not exhaustive. Deprecated aliases that I didn't touch:
+ `std.io.*`
+ `std.Build.*`
+ `std.builtin.Mode`
+ `std.zig.c_translation.CIntLiteralRadix`
+ anything in `src/`

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 7680c5330cbc9141b9a5444e30c512b6068ab50d to make it no longer possible.
InvalidHandle in RealPathError was a holdover from before d5312d53a066092ba9efd687e25b29a87eb6290c, which made realpath a compile error on WASI. However, InvalidHandle was also a possible error in the FreeBSD fallback implementation added in 537624734c4db9e0cdbdc0ebce57375d17172a70. 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

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.
Closes #18694
Closes #1774
Closes #2565

std: map NETNAME_DELETED to error.ConnectionResetByPeer

This was observed in writing to a network stream that was closed on the
read end.

overriding of os.heap.page_allocator
|
|
Thanks to @matklad for finding this additional NTSTATUS possibility when
calling GetFinalPathNameByHandle.

Export the T struct and winsize struct for targets which have it defined
in std.c. This struct defines libc constants for ioctl syscalls.

Encountered in a recent CI run on an aarch64-windows dev kit.
Pretty sure I disabled the virus scanner but it looks like it turned
itself back on with a Windows Update.
Rather than marking the new error code as unreachable in the places
where it is unexpected, this commit makes it return `error.Unexpected`.

In d7563a7753393d7f0d1af445276a64b8a55cb857, I misunderstood what `cc_t`
was supposed to do. Those V enum values are indices into the array.

This creates `tc_cflag_t` even though such a type is not defined by
libc.
I also collected the missing flag bits from all the operating systems.

* std.c: consolidate some definitions, making them share code. For
example, freebsd, dragonfly, and openbsd can all share the same
`pthread_mutex_t` definition.
* add type safety to std.c.O
- this caught a bug where mode flags were incorrectly passed as the
open flags.
* 3 fewer uses of usingnamespace keyword
* as per convention, remove purposeless field prefixes from struct field
names even if they have those prefixes in the corresponding C code.
* fix incorrect wasi libc Stat definition
* remove C definitions from incorrectly being in std.os.wasi
* make std.os.wasi definitions type safe
* go through wasi native APIs even when linking libc because the libc
APIs are problematic and wasteful
* don't expose WASI definitions in std.posix
* remove std.os.wasi.rights_t.ALL: this is a footgun. should it be all
future rights too? or only all current rights known? both are
the wrong answer.

std: make options a struct instance instead of a namespace
|
|
Same as previous commit, but for the libc interface.
|
|
Introduces type safety to this constant. Eliminates one use of
`usingnamespace`.
|
|
|
|
|
|
Uses `inline` only to forward the comptime-ness of the flags parameter
to function selection.
Also fixes doc comments in std.c.versionCheck.
|
|
The check for determining whether to use the fallback code has been
moved into an inline function as per Andrew's comments in #17954.
