These are great permutations, and there's nothing wrong with them
from a practical security perspective.
However, both were competing in the NIST lightweight crypto
competition.
Gimli didn't pass the 3rd selection round, and is not much used
in the wild besides Zig and libhydrogen. It will never be
standardized and is unlikely to get more traction in the future.
Xoodyak, that Xoodoo is the permutation of, was a finalist.
It has a lot of advantages and *might* be standardized without NIST.
But this is too early to tell, and too risky to commit to it
in a standard library.
For lightweight crypto, Ascon is the one that we know NIST will
standardize and that we can safely rely on from a usage perspective.
Switch to a traditional ChaCha-based CSPRNG, with an Ascon-based one
as an option for constrained systems.
Add a RNG benchmark by the way.
Gimli and Xoodoo served us well. Their code will be maintained,
but outside the standard library.
It is reasonable to pass -Dskip-non-native when unable to run foreign
binaries, however there is no option for being able to run foreign
static binaries but unable to run foreign dynamic binaries. This can
occur when qemu is installed but not cross glibc.
There are now very few stage1 cases remaining:
* `cases/compile_errors/stage1/obj/*` currently don't work correctly on
stage2. There are 6 of these, and most of them are probably fairly
simple to fix.
* `cases/compile_errors/async/*` and all remaining `safety/*` depend on
async; see #6025.
Resolves: #14849
In case the compiler outputted an object file that is not slicable
into subsections, entry point may overlap with a section atom which
is perfectly fine, so don't panic in that case.
as documented at
https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html
It is now equivalent to do
```
zig objcopy --only-keep-debug bar foo.debug
zig objcopy -g bar foo.tmp
zig objcopy --add-gnu-debuglink=foo.debug foo.tmp foo
rm foo.tmp
```
or
```
zig objcopy --only-keep-debug bar foo foo.debug
zig objcopy -g --add-gnu-debuglink=foo.debug bar foo
```
or
```
zig objcopy -g --extract-to=foo.debug bar foo
```
Support for the use case:
`zig objcopy --strip-all program stripped --extract-to stripped.dbg`
to separate the debug & symbols sections out to a companion file, with a corresponding a .gnu_debuglink.
note: this is "a minimal effort implementation"
It doesn't support all possibile elf files: there may be some sections type that need fixups, the program header may need fix up, ...
It was written for a specific use case (strip debug info to a sperate file, for linux 64-bits executables built with `zig` or `zig c++` )
It doesn't support 32-bit files, or file with non-native endianess.
* Fix GetFileInformationByHandle compile error
The wrapper function was mistakenly referencing ntdll.zig when the actual function is declared in kernel32.zig.
* delete GetFileInformationByHandle since it's not used by the stdlib
If the shared library is a relative path, dirname will return null causing a segfault. In the case I debugged, the current directory was already in RPATH so just ignoring this case seems a reasonable fix. After this fix "make" and "make test" pass for mimalloc.
Closes#13766
This function is unused, and the current implementation contains a few footguns:
- The current wrapper treats all possible errors as unexpected, even likely ones like BUFFER_OVERFLOW (which is returned if the size of the out_buffer is too small to contain all the variable-length members of the requested info, which the user may not actually care about)
- Each caller may need to handle errors differently, different errors might be possible depending on the FILE_INFORMATION_CLASS, etc, and making a wrapper that handles all of those different use-cases nicely seems like it'd be more trouble than it's worth (FILE_INFORMATION_CLASS has 76 different possible values)
If a wrapper for NtQueryInformationFile is wanted, then it should probably have wrapper functions per-use-case, like how QueryObjectName wraps NtQueryObject for the `ObjectNameInformation` class
* use the same hash function as the rest of the steps
* fix race condition due to a macOS oddity.
* fix race condition due to file truncation (rename into place instead)
* integrate with marking Step.result_cached. check if the file already
exists with fs.access before doing anything else.
* use a directory so that the file basename can be "options.zig"
instead of a hash digest.
* better error reporting in case of file system failures.
