2022-04-16stdlib std.os: Improve wasi-libc parity for WASI CWD emulationCody Tapscott
Two major changes here: 1. We store the CWD as a simple `[]const u8` and lookup Preopens for every absolute or CWD-referenced file operation, based on the Preopen with the longest match (i.e. most specific path) 2. Preorders are normalized to POSIX absolute paths at init time. Behavior depends on the "cwd_root" parameter of `initPreopensWasi`: `cwd_root` is used for any Preopens that start with "." For example: "./foo/bar" - inits to -> "{cwd_root}/foo/bar" "foo/bar" - inits to -> "/foo/bar" "/foo/bar" - inits to -> "/foo/bar" `cwd_root` must be an absolute path. Using "/" as `cwd_root` gives behavior similar to wasi-libc.
2022-03-03stdlib WASI: Add realpath() support for non-absolute PreopensCody Tapscott
2022-03-03stdlib: Add emulated CWD to std.os for WASI targetsCody Tapscott
This adds a special CWD file descriptor, AT.FDCWD (-2), to refer to the current working directory. The `*at(...)` functions look for this and resolve relative paths against the stored CWD. Absolute paths are dynamically matched against the stored Preopens. "os.initPreopensWasi()" must be called before std.os functions will resolve relative or absolute paths correctly. This is asserted at runtime. Support has been added for: `open`, `rename`, `mkdir`, `rmdir`, `chdir`, `fchdir`, `link`, `symlink`, `unlink`, `readlink`, `fstatat`, `access`, and `faccessat`. This also includes limited support for `getcwd()` and `realpath()`. These return an error if the CWD does not correspond to a Preopen with an absolute path. They also do not currently expand symlinks.

2022-01-11std: fix path joining on UEFIfifty-six
UEFI uses `\` for paths exclusively. This changes std.fs.path to use `\` for UEFI path joining. Also adds a few tests regarding it, specifically in making sure double-separators do not result from path joining, as the UEFI spec says to convert any that result from joining into single separators (UEFI Spec Version 2.7, pg. 448).

GetCurrentDirectory returns a path with a trailing slash iff the cwd is a root directory, making the code in `resolveWindows` return an invalid path with two consecutive slashes. Closes #10093
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.

2020-12-11std.fs.path.extension: different behavior for ending dotAndrew Kelley
extension("a.") now returns "." instead of "". This matches both Python and Node.js standard library behavior as well as my personal opinion on how this function should be defined. Apologies for missing this in the code review.

2020-11-13std.fs.path.dirname: return null when input path is rootAndrew Kelley
This intentionally diverges from the unix dirname command, as well as Python and Node.js standard libraries, which all have this edge case return the input path, unmodified. This is a footgun, and nobody should have ever done it this way. Even the man page contradicts the behavior. It says: "strip last component from file name". Now consider, if you remove the last item from an array of length 1, then you have now an array of length 0. After you strip the last component, there should be no components remaining. Clearly, returning the input parameter unmodified in this case does not match the documented behavior. This is my justification for taking a stand on this API design. closes #6746 closes #6727 closes #6584 closes #6592 closes #6602

2020-05-18Add/fix missing WASI functionality to pass libstd testsJakub Konka
This rather large commit adds/fixes missing WASI functionality in `libstd` needed to pass the `libstd` tests. As such, now by default tests targeting `wasm32-wasi` target are enabled in `test/tests.zig` module. However, they can be disabled by passing the `-Dskip-wasi=true` flag when invoking the `zig build test` command. When the flag is set to `false`, i.e., when WASI tests are included, `wasmtime` with `--dir=.` is used as the default testing command. Since the majority of `libstd` tests were relying on `fs.cwd()` call to get current working directory handle wrapped in `Dir` struct, in order to make the tests WASI-friendly, `fs.cwd()` call was replaced with `testing.getTestDir()` function which resolved to either `fs.cwd()` for non-WASI targets, or tries to fetch the preopen list from the WASI runtime and extract a preopen for '.' path. The summary of changes introduced by this commit: * implement `Dir.makeDir` and `Dir.openDir` targeting WASI * implement `Dir.deleteFile` and `Dir.deleteDir` targeting WASI * fix `os.close` and map errors in `unlinkat` * move WASI-specific `mkdirat` and `unlinkat` from `std.fs.wasi` to `std.os` module * implement `lseek_{SET, CUR, END}` targeting WASI * implement `futimens` targeting WASI * implement `ftruncate` targeting WASI * implement `readv`, `writev`, `pread{v}`, `pwrite{v}` targeting WASI * make sure ANSI escape codes are _not_ used in stderr or stdout in WASI, as WASI always sanitizes stderr, and sanitizes stdout if fd is a TTY * fix specifying WASI rights when opening/creating files/dirs * tweak `AtomicFile` to be WASI-compatible * implement `os.renameatWasi` for WASI-compliant `os.renameat` function * implement sleep() targeting WASI * fix `process.getEnvMap` targeting WASI

2020-02-28introduce operating system version ranges as part of the targetAndrew Kelley
* 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

2019-11-27remove type coercion from array values to referencesAndrew Kelley
* 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.
