breaking: std.os read/write functions + sendfile
* rework os.sendfile and add macosx support, and a fallback
   implementation for any OS.
 * fix sendto compile error
 * std.os write functions support partial writes. closes #3443.
 * std.os pread / pwrite functions can now return `error.Unseekable`.
 * std.fs.File read/write functions now have readAll/writeAll variants
   which loop to complete operations even when partial reads/writes
   happen.
 * Audit std.os read/write functions with respect to Linux returning
   EINVAL for lengths greater than 0x7fff0000.
 * std.os read/write shim functions do not unnecessarily loop. Since
   partial reads/writes are part of the API, the caller will be forced
   to loop anyway, and so that would just be code bloat.
 * Improve doc comments
 * Add a non-trivial test for std.os.sendfile
 * Fix std.os.pread on 32 bit Linux
 * Add missing SYS_sendfile bit on aarch64

introduce operating system version ranges as part of the target
* re-introduce `std.build.Target` which is distinct from `std.Target`.
   `std.build.Target` wraps `std.Target` so that it can be annotated as
   "the native target" or an explicitly specified target.
 * `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a
   struct which has the tag as well as version range information.
 * `std.elf` gains some more ELF header constants.
 * `std.Target.parse` gains the ability to parse operating system
   version ranges as well as glibc version.
 * Added `std.Target.isGnuLibC()`.
 * self-hosted dynamic linker detection and glibc version detection.
   This also adds the improved logic using `/usr/bin/env` rather than
   invoking the system C compiler to find the dynamic linker when zig
   is statically linked. Related: #2084
   Note: this `/usr/bin/env` code is work-in-progress.
 * `-target-glibc` CLI option is removed in favor of the new `-target`
   syntax. Example: `-target x86_64-linux-gnu.2.27`

update std lib to integrate with libc for environ
closes #3511
2020-02-22 15:59:13 -05:00

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.

std.os.getrusage: add C extern fn and reserved field
* add reserved field to match musl struct definition so that
   it will work with musl libc.
 * add libc getrusage so that it will work with libc

what's not done in this branch is:
 * test coverage. See #1629, which should also aim to provide
   general test coverage for the std lib.
 * rusage struct bits for non-linux operating systems

breaking: improve std.fs directory handling API
* Added `std.c.unlinkat` and `std.os.unlinkat`.
 * Removed `std.fs.MAX_BUF_BYTES` (this declaration never made it to
   master branch)
 * Added `std.fs.Dir.deleteTree` to be used on an open directory handle.
 * `std.fs.deleteTree` has better behavior for both relative and
   absolute paths. For absolute paths, it opens the base directory
   and uses that handle for subsequent operations. For relative paths,
   it does a similar strategy, using the cwd handle.
 * The error set of `std.fs.deleteTree` is improved to no longer have
   these possible errors:
   - OutOfMemory
   - FileTooBig
   - IsDir
   - DirNotEmpty
   - PathAlreadyExists
   - NoSpaceLeft
 * Added `std.fs.Dir.posix_cwd` which is a statically initialized
   directory representing the current working directory.
 * The error set of `std.Dir.open` is improved to no longer have these
   possible errors:
   - FileTooBig
   - IsDir
   - NoSpaceLeft
   - PathAlreadyExists
   - OutOfMemory
 * Added more alternative functions to `std.fs` for when the path
   parameter is a null terminated string. This can sometimes be more
   effecient on systems which have an ABI based on  null terminated
   strings.
 * Added `std.fs.Dir.openDir`, `std.fs.Dir.deleteFile`, and
   `std.fs.Dir.deleteDir` which all operate on an open directory handle.
 * `std.fs.Walker.Entry` now has a `dir` field, which can be used to do
   operations directly on `std.fs.Walker.Entry.basename`, avoiding
   `error.NameTooLong` for deeply nested paths.
 * Added more docs to `std.os.OpenError`

This commit does the POSIX components for these changes. I plan to
follow up shortly with a commit for Windows.
