std.crypto has quite a few instances of breaking naming conventions.
This is the beginning of an effort to address that.
Deprecates `std.crypto.utils`.
* Upgrade from u8 to usize element types.
- WebAssembly assumes u64. It should probably try to be target-aware
instead.
* Move the covered PC bits to after the header so it goes on the same
page with the other rapidly changing memory (the header stats).
depends on the semantics of accepted proposal #19755closes#20994
The previous mecanism for linux distributions to delivers debug info into `/usr/lib/debug` no longer seems in use.
the current mecanism often is using `debuginfod` (https://sourceware.org/elfutils/Debuginfod.html)
This commit only tries to load already available debuginfo but does not try to make any download requests.
the user can manually run `debuginfod-find debuginfo PATH` to populate the cache.
- look up the debuglink file in the directory of the executable file (instead of the cwd)
- fix parsing of debuglink section (the 4-byte alignement is within the file, unrelated to the in-memory address)
The signature is documented as:
int link(const char *, const char *);
(see https://man7.org/linux/man-pages/man2/link.2.html or https://man.netbsd.org/link.2)
And its not some Linux extension, the [syscall
implementation](21b136cc63/fs/namei.c (L4794-L4797))
only expects two arguments too.
It probably *should* have a flags parameter, but its too late now.
I am a bit surprised that linking glibc or musl against code that invokes
a 'link' with three parameters doesn't fail (at least, I couldn't get any
local test cases to trigger a compile or link error).
The test case in std/posix/test.zig is currently disabled, but if I
manually enable it, it works with this change.
Due to the `std.crypto.ecdsa.KeyPair.create` taking and optional of seed, even if the seed is generated, cross-compiling to the environments without standard random source (eg. wasm) (`std.crypto.random.bytes`) will fail to compile.
This commit changes the API of the problematic function and moves the random seed generation to a new utility function.
* libfuzzer: track unique runs instead of deduplicated runs
- easier for consumers to notice when to recheck the covered bits.
* move common definitions to `std.Build.Fuzz.abi`.
build runner sends all the information needed to fuzzer web interface
client needed in order to display inline coverage information along with
source code.
* libfuzzer: close file after mmap
* fuzzer/main.js: connect with EventSource and debug dump the messages.
currently this prints how many fuzzer runs have been attempted to
console.log.
* extract some `std.debug.Info` logic into `std.debug.Coverage`.
Prepares for consolidation across multiple different executables which
share source files, and makes it possible to send all the
PC/SourceLocation mapping data with 4 memcpy'd arrays.
* std.Build.Fuzz:
- spawn a thread to watch the message queue and signal event
subscribers.
- track coverage map data
- respond to /events URL with EventSource messages on a timer
