This function is needed when a library exposes one of its own library
dependency's headers as part of its own public API.
Also, improve error message when a file system error occurs during
install file step.
This includes a breaking change:
std.compress.gzip.GzipStream renamed to
std.compress.gzip.Decompress
This follows the same naming convention as std.compress.xz so that the
stream type can be passed as a comptime parameter.
* add xz to std.compress
* prefer importing std.zig by file name, to reduce reliance on the
standard library being a special case.
* extract some types from inside generic functions. These types are the
same regardless of the generic parameters.
* expose some more types in the std.compress.xz namespace.
* rename xz.stream to xz.decompress
* rename check.Kind to Check
* use std.leb for LEB instead of a redundant implementation
All but 3 callsites of this function in the standard library and
compiler were unnecessary and were removed in faf2fd18.
In this commit, the remaining 3 callsites are removed. One of them
turned out to also be unnecessary and has been replaced by slicing
directly with the length..
The 2 remaining callsites were in the very pointer-math heavy
std/os/linux/vdso.zig code which should perhaps be refactored to better
utilize slices. These 2 callsites are replaced with a plain
@ptrCast([*:0]u8, ptr) though could likely use std.mem.sliceTo() if the
surrounding code was refactored.
In commit 3542dbf0ea5 (langref: add section numbers) I accidentally
added an extra closing curly bracket at the end of the style element.
Sorry for not validating the HTML file before creating the PR.
Update the genToc funtion to make the name required in the Code node,
and add an additional optional field for the expected error, to use with
test_err, test_safety and obj_err.
Update langref.html.in to ensure all code blocks have a name that
- is unique, so that a doctest can be identified by it
- is descriptive
For test, test_err and test_safefy, ensure that the doctest name starts
with "test_", excluding doctests in the "Zig Test" section and doctests
that are imported by other doctests.
Ensure that the indentation of code_begin and code_end blocks are
consistent.
Fix a typo in pointer_arthemtic.
This fixes a bug in std.net caused during the introduction of
meta.assumeSentinel due to the unfortunate semantics of mem.span()
This leaves only 3 remaining uses of meta.assumeSentinel() in the
standard library, each of which could be a simple @ptrCast([*:0]T, foo)
instead. I think this function should likely be removed.
This avoids a warning that sometimes occurs when providing both a
-target argument that contains a version as well as the
-mmacosx-version-min argument. Zig provides the correct value in both
places, so it doesn't matter which one gets overridden.
Previously, if a source file was referenced from multiple packages, it
just became owned by the first one AstGen happened to reach; this was a
problem, because it could lead to inconsistent behaviour in the compiler
based on a race condition. This could be fixed by just analyzing such
files multiple times - however, it was pointed out by Andrew that it
might make more sense to enforce files being part of at most a single
package. Having a file in multiple packages would not only impact
compile times (due to Sema having to run multiple times on potentially a
lot of code) but is also a confusing anti-pattern which more often than
not is a mistake on the part of the user.
Resolves: #13662
By @Vexu's suggestion, since fetching the name from the parent package
is error-prone and complex, and optimising Package for size isn't really
a priority.
