this also deletes C string literals from the language, and then makes
the std lib changes and compiler changes necessary to get the behavior
tests and std lib tests passing again.
Show differing pointer values when comparing pointers instead of the
content they point to.
It's confusing for a test to say "expected S{.x = 1}, found S{.x = 1}"
as illustrated below when it was the pointers that differed.
There seems to be different rules for when a pointer is dereferenced by
the printing routine depending on its type. I don't fully grok this but
it's also illustrated below.
const std = @import("std");
const S = struct { x: u32 };
// before: ...expected S{ .x = 1 }, found S{ .x = 1 }
// after: ...expected S@7ffcd20b7798, found S@7ffcd20b7790
test "compare_ptr_to_struct" {
var a = S{.x = 1};
var b = S{.x = 1};
std.testing.expectEqual(&a, &b);
}
// before: ...expected u32@7fff316ba31c, found u32@7fff316ba318
// after: ...expected u32@7ffecec622dc, found u32@7ffecec622d8
test "compare_ptr_to_scalar" {
var a: u32 = 1;
var b: u32 = 1;
std.testing.expectEqual(&a, &b);
}
Thanks to the Windows Process Environment Block, it is possible to
obtain handles to the standard input, output, and error streams without
possibility of failure.
This implements stage1 parser support for anonymous struct literal
syntax (see #685), as well as semantic analysis support for anonymous
struct literals and anonymous list literals (see #208). The semantic
analysis works when there is a type coercion in the result location;
inferring the struct type based on the values in the literal is not
implemented yet. Also remaining to do is zig fmt support for this new
syntax and documentation updates.
parseString() created a copy of the string using the wrong allocator.
Instead of using the ArenaAllocator, it was using the allocator passed
into Parser.init(). This lead to a leak as the copied string was not
freed when the ArenaAllocator was deinited.
* Delete `std.net.TmpWinAddr`. I don't think that was ever meant to
be a real thing.
* Delete `std.net.OsAddress`. This abstraction was not helpful.
* Rename `std.net.Address` to `std.net.IpAddress`. It is now an extern
union of IPv4 and IPv6 addresses.
* Move `std.net.parseIp4` and `std.net.parseIp6` to the
`std.net.IpAddress` namespace. They now return `IpAddress` instead of
`u32` and `std.net.Ip6Addr`, which is deleted.
* Add `std.net.IpAddress.parse` which accepts a port and parses either
an IPv4 or IPv6 address.
* Add `std.net.IpAddress.parseExpectingFamily` which additionally
accepts a `family` parameter.
* `std.net.IpAddress.initIp4` and `std.net.IpAddress.initIp6` are
improved to directly take the address fields instead of a weird
in-between type.
* `std.net.IpAddress.port` is renamed to `std.net.IpAddress.getPort`.
* Added `std.net.IpAddress.setPort`.
* `os.sockaddr` struct on all targets is improved to match the
corresponding system struct. Previously I had made it a union of
sockaddr_in, sockaddr_in6, and sockaddr_un. The new abstraction for
this is now `std.net.IpAddress`.
* `os.sockaddr` and related bits are added for Windows.
* `os.sockaddr` and related bits now have the `zero` fields default
to zero initialization, and `len` fields default to the correct size.
This is enough to abstract the differences across targets, and so
no more switch on the target OS is needed in `std.net.IpAddress`.
* Add the missing `os.sockaddr_un` on FreeBSD and NetBSD.
* `std.net.IpAddress.initPosix` now takes a pointer to `os.sockaddr`.
* delete the std/event/net directory
* `std.event.Loop.waitUntilFdReadable` and related functions
no longer have possibility of failure. On Linux, they fall
back to poll() and then fall back to sleep().
* add some missing `noasync` decorations in `std.event.Loop`
* redo the `std.net.Server` API. it's quite nice now, but
shutdown does not work cleanly. There is a race condition with
close() that I am actively working on.
* move `std.io.OutStream` to its own file to match `std.io.InStream`.
I started working on making `write` integrated with evented I/O,
but it got tricky so I backed off and filed #3557. However
I did integrate `std.os.writev` and `std.os.pwritev` with evented I/O.
* add `std.Target.stack_align`
* move networking tests to `lib/std/net/test.zig`
* add `std.net.tcpConnectToHost` and `std.net.tcpConnectToAddress`.
* rename `error.UnknownName` to `error.UnknownHostName` within the
context of DNS resolution.
* add `std.os.readv`, which is integrated with evented I/O.
* `std.os.preadv`, is now integrated with evented I/O.
* `std.os.accept4` now asserts that ENOTSOCK and EOPNOTSUPP never
occur (misuse of API), instead of returning errors.
* `std.os.connect` is now integrated with evented I/O.
`std.os.connect_async` is gone. Just use `std.os.connect`.
* fix false positive dependency loop regarding async function frames
* add more compile notes to help when dependency loops occur
in determining whether a function is async.
* ir: change an assert to ir_assert to make it easier to find
workarounds for when such an assert is triggered. In this case
it was trying to parse an IPv4 address at comptime.
* Add some documentation for standard library things.
Added a bunch of descriptions for array_list.
Added some usage notes for failing_allocator.
Documented some of mem.Allocator.
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.
* All the data types from `@import("builtin")` are moved to
`@import("std").builtin`. The target-related types are moved
to `std.Target`. This allows the data types to have methods, such as
`std.Target.current.isDarwin()`.
* `std.os.windows.subsystem` is moved to
`std.Target.current.subsystem`.
* Remove the concept of the panic package from the compiler
implementation. Instead, `std.builtin.panic` is always the panic
function. It checks for `@hasDecl(@import("root"), "panic")`,
or else provides a default implementation.
This is an important step for multibuilds (#3028). Without this change,
the types inside the builtin namespace look like different types, when
trying to merge builds with different target settings. With this change,
Zig can figure out that, e.g., `std.builtin.Os` (the enum type) from one
compilation and `std.builtin.Os` from another compilation are the same
type, even if the target OS value differs.
The sockaddr pointer and size of the accept function points to a data structure that can only be determined at runtime. The only requirement is that it must be large enough to hold 2 bytes for the address family value. Typeical usage of the socket API is for UDP/TCP IPv4 and IPv6 sockets, which use sockaddr_in and sockaddr_in6. And some sockets can actually support both simultaneously in which case the app may want to have access to the size of the returned sockaddr. Operating systems can even support custom protocols where they use custom sockaddr data structures. In this case the standard library would have no knowledge of the actual size of the sockaddr being passed into the accept function. In this case the standard library should defer to the app to pass in the size of their structure.
* 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.
* use erase rest of line escape code.
* use `stderr.supportsAnsiEscapeCodes` rather than `isTty`.
* respect `--color off`
* avoid unnecessary recursion
* add `Progress.log`
* disable the progress std lib test since it's noisy and uses
`time.sleep()`.
* enable/integrate progress printing with the default test runner
* `std.os.execve` had the wrong name; it should have been
`std.os.execvpe`. This is now corrected.
* introduce `std.os.execveC` which does not look at PATH, and uses
null terminated parameters, matching POSIX ABIs. It does not
require an allocator.
* fix typo nonsense doc comment in `std.fs.MAX_PATH_BYTES`.
* introduce `std.os.execvpeC`, which is like `execvpe` except it
uses null terminated parameters, matching POSIX ABIs, and thus
does not require an allocator.
* `std.os.execvpe` implementation is reworked to only convert
parameters and then delegate to `std.os.execvpeC`.
* `std.os.execvpeC` improved to handle `ENOTDIR`. See #3415
Some keyboard layouts produces a different ev.which value in firefox
for ? than 191, eg. the Swedish QWERTY one produces 171. Chrome/chromium
doesn't have this issue.
* introduce std.json.WriteStream API for writing json
data to a stream
* add WIP tools/merge_anal_dumps.zig for merging multiple semantic
analysis dumps into one. See #3028
* add std.json.Array, improves generated docs
* add test for `std.process.argsAlloc`, improves test coverage and
generated docs
