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
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.
Reapplies 1585ed637d101ed16adb6b9ebdfa465299bfdb13 which was reverted in
f3adbe249b0dfad91318916142a33619232a968f.
I removed use of `usingnamespace` in this commit.
@semarie audited this struct definition.
