added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string
This was done by regex substitution with `sed`. I then manually went
over the entire diff and fixed any incorrect changes.
This diff also changes a lot of `callconv(.C)` to `callconv(.c)`, since
my regex happened to also trigger here. I opted to leave these changes
in, since they *are* a correct migration, even if they're not the one I
was trying to do!
Fixes#21446
Both UefiPoolAllocator and UefiRawPoolAllocator were
passing the value of `log2_ptr_align` directly to
`mem.alignAllocLen` which expects a alignment value.
Both of these calls to `mem.alignAllocLen` are pointless
and the result of the alignment both always true, and
was thrown away anyway.
I have removed these calls entirely.
Most of these changes seem like improvements. The PDB thing had a TODO
saying it used to crash; I anticipate it works now, we'll see what CI
does.
The `std.os.uefi` field renames are a notable breaking change.
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938.
This eliminates some simple usages of `usingnamespace` in the standard
library. This construct may in future be removed from the language, and
is generally an inappropriate way to formulate code. It is also
problematic for incremental compilation, which may not initially support
projects using it.
I wasn't entirely sure what the appropriate namespacing for the types in
`std.os.uefi.tables` would be, so I ofted to preserve the current
namespacing, meaning this is not a breaking change. It's possible some
of the moved types should instead be namespaced under `BootServices`
etc, but this can be a future enhancement.
This is a breaking change.
This commit applies the following rules to std.os.uefi:
* avoid redundant names in the namespace such as "protocol.FooProtocol"
* don't initialize struct field to undefined. do that at the
initialization site if you want that, or create a named constant that
sets all the fields to undefined.
* avoid the word "data", "info", "context", "state", "details", or
"config" in the type name, especially if a word from that category is
already in the type name.
* embrace tree structure
After following these rules, `usingnamespace` disappeared naturally.
This commit eliminates 26/53 (49%) instances of `usingnamespace` in the
standard library. All these uses were due to not understanding how
to properly use namespaces.
I did not test this commit. The standard library UEFI code is
experimental and pull requests have been accepted with minimal vetting.
Users of std.os.uefi will need to submit follow-up pull requests to fix
up whatever regressions this commit introduces, this time without
abusing namespaces (pun intended).
I tested this and this definitely compiles and these
changes were done programmatically but if there's still anything wrong
it shouldn't be hard to fix.
With this change it's going to be very easy to make further adjustments
to the calling conventions of all these external UEFI functions.
Closes#16309
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
Anecdote 1: The generic version is way more popular than the non-generic
one in Zig codebase:
git grep -w alignForward | wc -l
56
git grep -w alignForwardGeneric | wc -l
149
git grep -w alignBackward | wc -l
6
git grep -w alignBackwardGeneric | wc -l
15
Anecdote 2: In my project (turbonss) that does much arithmetic and
alignment I exclusively use the Generic functions.
Anecdote 3: we used only the Generic versions in the Macho Man's linker
workshop.
* Changed the interface to align with the new allocator interface.
* Fixed bug where not enough memory was allocated for the header or to
align the pointer.
There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.
* std.os.uefi: integer backed structs, add tests to catch regressions
device_path_protocol now uses extern structs with align(1) fields because
the transition to integer backed packed struct broke alignment
added comptime asserts that device_path_protocol structs do not violate
alignment and size specifications
This makes possible to query the memory map size from EFI firmware
without making any allocation beforehand. This makes possible to be
precise about the size of the allocation which will own a copy of
the memory map from the UEFI application.
