* std.unicode: Add more UTF-16 decoding functions
This mostly makes parts of Utf16LeIterator reusable
* std.json: Fix decoding of UTF-16 surrogate pairs
Before this commit, there were 524,288 codepoints that would get decoded improperly. After this commit, there are 0.
Fixes#16828
* Consistent decryption tail for all AEADs
* Remove outdated note
This was previously copied here from another function. There used
to be another comment on the tag verification linking to issue #1776,
but that one was not copied over. As it stands, this note seems fairly
misleading/irrelevant.
* Prettier docs
* Add note about plaintext contents to docs
* Capitalization
* Fixup missing XChaChaPoly docs
Previously, a relative path like `..` would:
- Attempt to be normalized (i.e. remove . and .. without any path resolution), but would error with TooManyParentDirs
- This would make wToPrefixedFileW run it through `RtlGetFullPathName_U` to do the necessary path resolution, but `RtlGetFullPathName_U` always resolves relative paths relative to the CWD
Instead, when TooManyParentDirs occurs, we now look up the path of the passed in `dir` (if it's non-null) and append the relative path to it before giving it to `RtlGetFullPathName_U`. If `dir` is null, then we just give it RtlGetFullPathName_U directly and let it resolve it relative to the CWD.
Closes#16779
* autodoc: init guide TOC work
* autodoc: working guides toc navigation
* autodoc: more improvements
* autodoc: ui refinements
* autodoc: new layout and init descriptions for namespaces in std.zig
* renamed enum_big_numbers_quoted option to enum_nonportable_numbers_as_strings
* updated stringify doc to mention the option
I also reversed the logic to determine whether an integer is nonportable,
it seemed easier to reason about.
I also took a stab at applying the new option to floats, but, I got stuck
at trying to print large floats, not sure if Zig supports that yet.
The previous magic numbers used `1 << 52`, which did not account for the
implicit leading one in the floating point format. The RFC is correct
when it uses an exponent of 53. Technically these exclusive endpoints
are also representable, but everyone including the RFC seems to use them
exclusively.
Also, delete special case optimizations related to the type which have
already been implemented in the zig compiler to produce comptime values
for tautological runtime comparisons.
std.json follows interoperability recommendations from RFC8259 to limit
JSON number values to those that fit inside an f64. However, since Zig
supports arbitrarily large JSON numbers, this breaks roundtrip data
congruence.
To appease both use cases, I've added an option `emit_big_numbers_quoted`
to StringifyOptions. It's disabled by default which preserves roundtrip
but can be enabled to favor interoperability.
Before this commit, you could use readElfDebugInfo independently with
one catch: the data is not freed since the deinitialization functions
for ModuleDebugInfo are private. This change makes them public so the
users of such function and similar can free the memory after the
debug symbols have been used.
* don't assert that the child process doesn't crash
* don't give a false negative on warnings printed to stderr
Also fix getSdk from the same file in the same way
This was discussed in #16597. It makes sense for most of the functions
in this file to be marked inline: many are simple helper functions so
inlining is likely a strict win, and having the return values be
comptime-known may improve userspace code in some cases by preventing it
from unintentionally checking properties of the target at runtime.
This changeset is somewhat conservative: the functions marked inline are
generally returning booleans or simple integers, and many are simple
one-line checks.
Without duping, users could get some unexpected behavior if they used a
string with a lifetime that didn't persist throughout the full build,
i.e. if it wasn't heap allocated, or if it was explicitly freed.
* Replaces the exit assembly with the function from std.
* Reads the top-of-stack struct at program startup that can get information
like the pid.
* Changes the read and write functions to use the Pread and Pwrite syscalls
instead of the depreciated _READ and _WRITE
* Changes the openat function to use flags instead of perms.
Plan9 does not support perms when opening, just when creating.
* Adds an errstr function to read the errstr buf created by the kernel
Implements issue #6451.
This was needed to support allocation on Plan 9 and now other operating
systems like DOS can also use it.
It is a modified version of the WasmAllocator since wasm also uses a
sbrk-esque allocation system.
This commit also adds the necessary system bits for sbrk to work on plan 9.
