By pulling out the parallel hashing setup from `CodeSignature.zig`,
we can now reuse it different places across MachO linker (for now;
I can totally see its usefulness beyond MachO, eg. in COFF or ELF too).
The parallel hasher is generic over actual hasher such as Sha256 or MD5.
The implementation is kept as it was.
For UUID calculation, depending on the linking mode:
* incremental - since it only supports debug mode, we don't bother with MD5
hashing of the contents, and populate it with random data but only once
per a sequence of in-place binary patches
* traditional - in debug, we use random string (for speed); in release,
we calculate the hash, however we use LLVM/LLD's trick in that we
calculate a series of MD5 hashes in parallel and then one an MD5 of MD5
final hash to generate digest.
- Previously, some of the compress tests used `@src()` in combination with `dirname` and `openDirAbsolute` to read test files at runtime, which both excludes platforms that `openDirAbsolute` is not implemented for (WASI) and platforms that `SourceLocation.file` is not absolute (this was true for me locally on Windows). Instead of converting the tests to use `fs.cwd().openDir`, they have been converted to use `@embedFile` to avoid any potential problems with the runtime cwd.
- In order to use `@embedFile`, some of the `[]u8` parameters needed to be changed to `[]const u8`; none of them needed to be non-const anyway
- The tests now use `expectEqual` and `expectEqualSlices` where appropriate for better diagnostics
This fixes a regression introduced in #12298 where colors would never reset in a Windows console because the attributes would be queried on every `setColor` call, and then try to 'reset' the attributes to what it just queried (i.e. it was essentially doing a complicated no-op on .Reset).
This fixes the problem while (I think) keeping with the spirit of the changes in #12298--that is, `TTY.Config` is not specifically tied to stderr like it was before #12298. To that end, detectTTYConfig now takes a `File` and that's what gets used to query the initial attributes to reset to.
(for context, before #12298, the first `setColor` call is where the reset attributes would get queried and it would always use stderr to do it)
#13666 introduced a footgun when using `toOwnedSlice` with `errdefer array_list.deinit()`, since `toOwnedSlice` could retain capacity if `resize` failed, meaning it would leak without `deinit` being called. This meant that the only correct way to use `toOwnedSlice` was with `defer` instead of `errdefer` to ensure that the ArrayList would get cleaned up.
Now, toOwnedSlice will now behave similarly to how it did before #13666, in that it will always clear the ArrayList's capacity if the resize/realloc succeeds.
This also reverts commit 05890a12f532ba9d58904a14381ec174b9efe473, which was contingent on the modified toOwnedSlice behavior.
Closes#13946
In glibc.zig, there were a few instances where the zig lib dir path name
incorrectly made its way into the cache namespace for various build
artifacts, resulting in unnecessary rebuilds of glibc.
Closes#13619
* revert changes to Module because the error set is consistent across
operating systems.
* remove duplicated Stat.fromSystem code and use a less redundant name.
* make fs.Dir.statFile follow symlinks, and avoid pointless control
flow through the posix layer.
This commit moves the logic from `std.build.InstallRawStep` into `zig
objcopy`. The options here are limited, but we can add features as
needed.
closes#9261
New issues can be opened for specific objcopy flag support.
