self-hosted libc detection * libc_installation.cpp is deleted. src-self-hosted/libc_installation.zig is now used for both stage1 and stage2 compilers. * (breaking) move `std.fs.File.access` to `std.fs.Dir.access`. The API now encourages use with an open directory handle. * Add `std.os.faccessat` and related functions. * Deprecate the "C" suffix naming convention for null-terminated parameters. "C" should be used when it is related to libc. However null-terminated parameters often have to do with the native system ABI rather than libc. "Z" suffix is the new convention. For example, `std.os.openC` is deprecated in favor of `std.os.openZ`. * Add `std.mem.dupeZ` for using an allocator to copy memory and add a null terminator. * Remove dead struct field `std.ChildProcess.llnode`. * Introduce `std.event.Batch`. This API allows expressing concurrency without forcing code to be async. It requires no Allocator and does not introduce any failure conditions. However it is not thread-safe. * There is now an ongoing experiment to transition away from `std.event.Group` in favor of `std.event.Batch`. * `std.os.execvpeC` calls `getenvZ` rather than `getenv`. This is slightly more efficient on most systems, and works around a limitation of `getenv` lack of integration with libc. * (breaking) `std.os.AccessError` gains `FileBusy`, `SymLinkLoop`, and `ReadOnlyFileSystem`. Previously these error codes were all reported as `PermissionDenied`. * Add `std.Target.isDragonFlyBSD`. * stage2: access to the windows_sdk functions is done with a manually maintained .zig binding file instead of `@cImport`. * Update src-self-hosted/libc_installation.zig with all the improvements that stage1 has seen to src/libc_installation.cpp until now. In addition, it now takes advantage of Batch so that evented I/O mode takes advantage of concurrency, but it still works in blocking I/O mode, which is how it is used in stage1. 2020-02-16 10:25:30 -08:00			`pub const Batch = @import("event/batch.zig").Batch;`

Instead the event loop run() function returns once there are no pending coroutines. * fix crash in ir.cpp for calling methods under some conditions * small progress self-hosted compiler, analyzing top level declarations * Introduce std.event.Lock for synchronizing coroutines * introduce std.event.Locked(T) for data that only 1 coroutine should modify at once. * make the self hosted compiler use multi threaded event loop * make std.heap.DirectAllocator thread-safe See #174 TODO: * call sched_getaffinity instead of hard coding thread pool size 4 * support for Windows and MacOS * #1194 * #1197 2018-07-05 12:09:02 -07:00			`}`
