* File.Writer.sendFile incorrectly used non-logical position.

This enables depth-related use cases without any dependency on the Walker's internal stack which doesn't always pertain to the actual depth of the current entry (i.e. recursing into a directory immediately affects the stack).
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
Btrfs at least supports 16 EiB files (limited in practice to 8EiB by the
Linux VFS code which uses signed 64-bit offsets). So fix the fs.zig test
case to expect either a FileTooBig or success from truncating a file to
8EiB. And test that beyond that size the offset is interpreted as a
negative number.
Fixes#24242
Add a test for std.fs.File's `setEndPos` (which is a simple wrapper around
`std.posix.ftruncate`) to exercise some success and failure paths.
Explicitly check that the `ftruncate` length isn't negative when
interpreted as a signed value. This avoids having to decode overloaded
`EINVAL` errors.
Add errno handling to Windows path to map INVALID_PARAMETER to FileTooBig.
Fixes#22960
Use error.AccessDenied for permissions (rights) failures on Wasi
(`EACCES`) and error.PermissionDenied (`EPERM`) for systemic failures.
And pass-through underlying Wasi errors (PermissionDenied or AccessDenied)
without mapping.
* use `tmp.dir.realpathAlloc()` to get full path into tmpDir instances
* use `testing.allocator` where that simplifies things (vs. manual ArenaAllocator for 1 or 2 allocs)
* Trust `TmpDir.cleanup()` to clean up contained files and sub-trees
* Remove some unnecessary absolute paths (enabling WASI to run the tests)
* Drop some no-longer necessary `[_][]const u8` casts
* Add scopes to reduce `var` usage in favor of `const`
Zig's copy of the `SYMLINK_{NO,}FOLLOW` constants from wasi-musl was
wrong, as were the `IFIFO` and `IFSOCK` file type flags. Fix these up,
and add comments pointing to exactly where they come from (as the
wasi-musl source has lots of unused, different definitions of these
constants).
Add tests for the Zig convention that WASM preopen 3 is the current
working directory. This is true for WASM with or without libc.
Enable several fs and posix tests that are now passing (not necessarily
because of this change) on wasm targets.
Fixes#20890.
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/`
this patch renames ComptimeStringMap to StaticStringMap, makes it
accept only a single type parameter, and return a known struct type
instead of an anonymous struct. initial motivation for these changes
was to reduce the 'very long type names' issue described here
https://github.com/ziglang/zig/pull/19682.
this breaks the previous API. users will now need to write:
`const map = std.StaticStringMap(T).initComptime(kvs_list);`
* move `kvs_list` param from type param to an `initComptime()` param
* new public methods
* `keys()`, `values()` helpers
* `init(allocator)`, `deinit(allocator)` for runtime data
* `getLongestPrefix(str)`, `getLongestPrefixIndex(str)` - i'm not sure
these belong but have left in for now incase they are deemed useful
* performance notes:
* i posted some benchmarking results here:
https://github.com/travisstaloch/comptime-string-map-revised/issues/1
* i noticed a speedup reducing the size of the struct from 48 to 32
bytes and thus use u32s instead of usize for all length fields
* i noticed speedup storing KVs as a struct of arrays
* latest benchmark shows these wall_time improvements for
debug/safe/small/fast builds: -6.6% / -10.2% / -19.1% / -8.9%. full
output in link above.
Now, all the tests that use `testWithAllSupportedPathTypes` will also run each test with both `/` and `\` as the path separator on Windows.
Also, removes the now-redundant "Dir.symLink with relative target that has a / path separator" since the same thing is now tested in the "Dir.readLink" test
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.

* 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.
