fix swapped logic for Windows
Remove `std.fs.deleteTree`. Callers instead should use
`std.fs.cwd().deleteTree`.

Add `std.fs.deleteTreeAbsolute` for when the caller has an absolute
path.

(breaking) clarify openDir API
* remove deprecated `std.fs.Dir` APIs
 * `std.fs.Dir.openDir` now takes a options struct with bool fields for
   `access_sub_paths` and `iterate`. It's now much more clear how
   opening directories works.
 * fixed the std lib and various zig code calling the wrong openDir
   function.
 * the runtime safety check for dir flags is removed in favor of the
   cheaper option of putting a comment on the same line as handling
   EBADF / ACCESS_DENIED, since that will show up in stack traces.

breaking changes to std.fs, std.os
* improve `std.fs.AtomicFile` to use sendfile()
   - also fix AtomicFile cleanup not destroying tmp files under some
     error conditions
 * improve `std.fs.updateFile` to take advantage of the new `makePath`
   which no longer needs an Allocator.
 * rename std.fs.makeDir to std.fs.makeDirAbsolute
 * rename std.fs.Dir.makeDirC to std.fs.Dir.makeDirZ
 * add std.fs.Dir.makeDirW and provide Windows implementation of
   std.os.mkdirat. std.os.windows.CreateDirectory is now implemented
   by calling ntdll, supports an optional root directory handle,
   and returns an open directory handle. Its error set has a few more
   errors in it.
 * rename std.fs.Dir.changeTo to std.fs.Dir.setAsCwd
 * fix std.fs.File.writevAll and related functions when len 0 iovecs
   supplied.
 * introduce `std.fs.File.writeFileAll`, exposing a convenient
   cross-platform API on top of sendfile().
 * `NoDevice` added to std.os.MakeDirError error set.
 * std.os.fchdir gets a smaller error set.
 * std.os.windows.CloseHandle is implemented with ntdll call rather than
   kernel32.

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`

closes #1907

improve handling of environment variables on Windows
std.os.getenv and std.os.getenvZ have nice compile errors when not linking
libc and using Windows.

std.os.getenvW is provided as a Windows-only API that does not require
an allocator. It uses the Process Environment Block.
std.process.getEnvVarOwned is improved to be a simple wrapper on top of
std.os.getenvW.

std.process.getEnvMap is improved to use the Process Environment Block
rather than calling GetEnvironmentVariableW.

std.zig.system.NativePaths uses process.getEnvVarOwned instead of
std.os.getenvZ, which works on Windows as well as POSIX.

update dl_iterate_phdr test case to new API 2020-02-17 17:22:32 -05:00
Andrew Kelley 4b02a39aa9
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.

Andrew Kelley 8186211404
improvements to memfd_create
* move test from std/io/test.zig to std/os/test.zig
 * do glibc version check, and make direct system call if
   glibc is too old
 * disable test when not linking libc, to avoid not working
   with outdated qemu version on the CI server. see #4019

remove type coercion from array values to references
* Implements #3768. This is a sweeping breaking change that requires
   many (trivial) edits to Zig source code. Array values no longer
   coerced to slices; however one may use `&` to obtain a reference to
   an array value, which may then be coerced to a slice.

 * Adds `IrInstruction::dump`, for debugging purposes. It's useful to
   call to inspect the instruction when debugging Zig IR.

 * Fixes bugs with result location semantics. See the new behavior test
   cases, and compile error test cases.

 * Fixes bugs with `@typeInfo` not properly resolving const values.

 * Behavior tests are passing but std lib tests are not yet. There
   is more work to do before merging this branch.

get rid of std.os.foo.is_the_target
It had the downside of running all the comptime blocks and resolving
all the usingnamespaces of each system, when just trying to discover if
the current system is a particular one.

For Darwin, where it's nice to use `std.Target.current.isDarwin()`, this
demonstrates the utility that #425 would provide.
