2025-10-29std.Thread.ResetEvent: make it more reusableAndrew Kelley
2025-07-11Remove numerous things deprecated during the 0.14 release cycleLinus Groh
Basically everything that has a direct replacement or no uses left. Notable omissions: - std.ArrayHashMap: Too much fallout, needs a separate cleanup. - std.debug.runtime_safety: Too much fallout. - std.heap.GeneralPurposeAllocator: Lots of references to it remain, not a simple find and replace as "debug allocator" is not equivalent to "general purpose allocator". - std.io.Reader: Is being reworked at the moment. - std.unicode.utf8Decode(): No replacement, needs a new API first. - Manifest backwards compat options: Removal would break test data used by TestFetchBuilder. - panic handler needs to be a namespace: Many tests still rely on it being a function, needs a separate cleanup.

2024-02-26Remove redundant test name prefixes now that test names are fully qualifiedRyan Liptak
Follow up to #19079, which made test names fully qualified. This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit: "priority_queue.test.std.PriorityQueue: shrinkAndFree" and the same test's name after the changes in this commit: "priority_queue.test.shrinkAndFree"
2023-11-22rework std.atomicAndrew Kelley
* move std.atomic.Atomic to std.atomic.Value * fix incorrect argument order passed to testing.expectEqual * make the functions be a thin wrapper over the atomic builtins and stick to the naming conventions. * remove pointless functions loadUnchecked and storeUnchecked. Instead, name the field `raw` instead of `value` (which is redundant with the type name). * simplify the tests by not passing every possible combination. Many cases were iterating over every possible combinations but then not even using the for loop element value! * remove the redundant compile errors which are already implemented by the language itself. * remove dead x86 inline assembly. this should be implemented in the language if at all.

2021-09-01std.os: more reorganization effortsAndrew Kelley
* std lib tests are passing on x86_64-linux with and without -lc * stage2 is building from source on x86_64-linux * down to 38 remaining uses of `usingnamespace`
2021-08-24remove redundant license headers from zig standard libraryAndrew Kelley
We already have a LICENSE file that covers the Zig Standard Library. We no longer need to remind everyone that the license is MIT in every single file. Previously this was introduced to clarify the situation for a fork of Zig that made Zig's LICENSE file harder to find, and replaced it with their own license that required annual payments to their company. However that fork now appears to be dead. So there is no need to reinforce the copyright notice in every single file.
2021-08-24std: [breaking] move errno to become an nonexhaustive enumAndrew Kelley
The primary purpose of this change is to eliminate one usage of `usingnamespace` in the standard library - specifically the usage for errno values in `std.os.linux`. This is accomplished by truncating the `E` prefix from error values, and making errno a proper enum. A similar strategy can be used to eliminate some other `usingnamespace` sites in the std lib.

2021-02-28std: Swap arguments in Thread.spawnLemonBoy
Beside the new order being consistent with the ThreadPool API and making more sense, this shuffling allows to write the context argument type in terms of the startFn arguments, reducing the use of anytype (eg. less explicit casts when using comptime_int parameters, yay). Sorry for the breakage. Closes #8082
2021-01-14organize std lib concurrency primitives and add RwLockAndrew Kelley
* move concurrency primitives that always operate on kernel threads to the std.Thread namespace * remove std.SpinLock. Nobody should use this in a non-freestanding environment; the other primitives are always preferable. In freestanding, it will be necessary to put custom spin logic in there, so there are no use cases for a std lib version. * move some std lib files to the top level fields convention * add std.Thread.spinLoopHint * add std.Thread.Condition * add std.Thread.Semaphore * new implementation of std.Thread.Mutex for Windows and non-pthreads Linux * add std.Thread.RwLock Implementations provided by @kprotty
