This test works by assuming that std.ArrayList will grow with a specific
capacity increasing pattern, which is an invalid assumption. Delete the
offending test.
I measured this against master branch and found no statistical
difference. Since this code is simpler and logically superior due to
always leaving sufficient unused capacity when growing, it is preferred
over status quo.
Adds `addFileContentArg` and `addPrefixedFileContentArg` to pass the content
of a file with a lazy path as an argument to a `std.Build.Step.Run`.
This enables replicating shell `$()` / cmake `execute_process` with `OUTPUT_VARIABLE`
as an input to another `execute_process` in conjuction with `captureStdOut`/`captureStdErr`.
To also be able to replicate `$()` automatically trimming trailing newlines and cmake
`OUTPUT_STRIP_TRAILING_WHITESPACE`, this patch adds an `options` arg to those functions
which allows specifying the desired handling of surrounding whitespace.
The `options` arg also allows to specify a custom `basename` for the output. e.g.
to add a file extension (concrete use case: Zig `@import()` requires files to have a
`.zig`/`.zon` extension to recognize them as valid source files).
The data structure was originally added in
41e1cd185b82a518c58c92544c45f0348c03ef74 and then removed in
50a336fff899ebd8a687c453ec6beb18a5a9baf9, but brought back in
711bf55eaa643c3d05640bebbf3e4315477b8ed8 for Decl in the compiler
frontend, and then the last reference to it was eliminated in
548a087fafeda5b07d2237d5137906b8d07da699 which removed Decl in favor of
Nav and Cau.
When building on macOS Tahoe, binaries were getting duplicate LC_RPATH
load commands which caused dyld to refuse to run them with a
"duplicate LC_RPATH" error that has become a hard error.
The duplicates occurred when library directories were being added
to rpath_list twice:
- from lib_directories
- from native system paths detection which includes the same dirs
This can be re-evaluated at a later time, but at the moment the
performance and stability concerns hold it back. Additionally, it
promotes a non-smithing approach to fuzz tests.
This PR significantly improves the capabilities of the fuzzer.
The changes made to the fuzzer to accomplish this feat mostly include
tracking memory reads from .rodata to determine fresh inputs, new
mutations (especially the ones that insert const values from .rodata
reads and __sanitizer_conv_const_cmp), and minimizing found inputs.
Additionally, the runs per second has greatly been increased due to
generating smaller inputs and avoiding clearing the 8-bit pc counters.
An additional feature added is that the length of the input file is now
stored and the old input file is rerun upon start.
Other changes made to the fuzzer include more logical initialization,
using one shared file `in` for inputs, creating corpus files with
proper sizes, and using hexadecimal-numbered corpus files for
simplicity.
Furthermore, I added several new fuzz tests to gauge the fuzzer's
efficiency. I also tried to add a test for zstandard decompression,
which it crashed within 60,000 runs (less than a second.)
Bug fixes include:
* Fixed a race conditions when multiple fuzzer processes needed to use
the same coverage file.
* Web interface stats now update even when unique runs is not changing.
* Fixed tokenizer.testPropertiesUpheld to allow stray carriage returns
since they are valid whitespace.
I’ve been typing `zig fmt **/.zig` for a long time, until I discovered
that the argument can actually be a directory.
Mention this feature explicitly in the help message.
* Remove the generic model; we already have generic_la32 and generic_la64 and
pick appropriately based on bitness.
* Remove the loongarch64 model. We used this as our baseline for 64-bit, but it's
actually pretty misleading and useless; it doesn't represent any real CPU and
has less features than generic_la64.
* Add la64v1_0 and la64v1_1 models.
* Change our baseline CPU model for 64-bit to be la64v1_0, thus adding LSX to
the baseline feature set.
Ascon is the family of cryptographic constructions standardized by NIST
for lightweight cryptography.
The Zig standard library already included the Ascon permutation itself,
but higher-level constructions built on top of it were intentionally
postponed until NIST released the final specification.
That specification has now been published as NIST SP 800-232:
https://csrc.nist.gov/pubs/sp/800/232/final
With this publication, we can now confidently include these constructions
in the standard library.
* std.sort.pdq: fix out-of-bounds access in partialInsertionSort
When sorting a sub-range that doesn't start at index 0, the
partialInsertionSort function could access indices below the range
start. The loop condition `while (j >= 1)` didn't respect the
arbitrary range boundaries [a, b).
This changes the condition to `while (j > a)` to ensure indices
never go below the range start, fixing the issue where pdqContext
would access out-of-bounds indices.
Fixes#25250
In ed25519.zig, we checked if a test succeeds, in which case we
returned an error. This was confusing, and Andrew pointed out that
Zig weights branches against errors by default.
* test: remove test-compare-output and test-asm-link tests
These were low value and unfocused tests. We already have coverage of the
important aspects of these tests elsewhere. Additionally, there was really no
need for these to have their own test harness.
* test: rename issue_8550 standalone test to compile_asm
* test: rename backend=stage2 to backend=selfhosted, and add backend=auto
backend=auto (now the default if backend is omitted) means to let the compiler
pick whatever backend it wants as the default. This is important for platforms
where we don't yet have a self-hosted backend, such as loongarch64.
Also purge a bunch of redundant target=native.
* test: delete old stage1 compile_errors tests
generic_function_returning_opaque_type.zig was salvaged as it's still worth
having.
* test: pull tests in test/cases/llvm/ up to test/cases/
There is nothing inherently LLVM-specific about any of these.
* test: remove @cImport usage in interdependent_static_c_libs
* test: move glibc_compat from link to standalone tests
This is not really testing the linker.
* build: -Dskip-translate-c now implies -Dskip-run-translated-c
* build: skip test-cimport when -Dskip-translate-c is given
