Use i32 instead of isize for os.timeval's for socket read/write
timeouts.
Add a comptime check to resolveScopeID to see if `IFNAMESIZE` is
available on the host. If it is not available, return an error
indicating that resolving the scope ID of a IPv6 address is not yet
supported on the host platform.
Address comments from @ifreund and @MasterQ32 to address unsafeness and
ergonomics of the `Address` API.
Rename the `TCP` namespace to `tcp` as it does not contain any
top-level fields.
Fix missing reference to `sockaddr` which was identified by @kprotty in
os/bits/linux/arm64.zig.
The `Socket` abstraction was refactored to only comprise of methods that
can be generically used/applied to all socket domains and protocols.
A more comprehensive IPv4/IPv6 module derived from @LemonBoy's earlier
work was implemented under `std.x.os.IPv4` and `std.x.os.IPv6`. Using
this module, one can then combine them together into a union for example
in order to optimize memory usage when dealing with socket addresses.
A `TCP.Client` and `TCP.Listener` abstraction is introduced that is one
layer over the `Socket` abstraction, which isolates methods that can
only be applied to a "client socket" and a "listening socket". All prior
tests from the `Socket` abstraction, which all previously operated
assuming the socket is operating via. TCP/IP, were moved. All TCP socket
options were also moved into the `TCP.Client` and `TCP.Listener`
abstractions respectively away from the `Socket` abstraction.
Some additional socket options from @LemonBoy's prior PR for Darwin were
also moved in (i.e. SIGNOPIPE).
Leave the minimum amount of stack space required by the ABI (16 * 8
bytes for the window contents plus 6 * 8 bytes for the input arguments)
on the new thread stack.
Uses verified code generated by fiat-crypto for field arithmetic, and complete formulas to avoid side channels.
There's still plenty of room for optimizations, especially with a fixed base. But this gives us a framework to easily add other similar curves.
* Add a yield pattern for PowerPC64
* Fix compile error on pre-v6 ARM targets
* Use isb instead of yield on AArch64 to give the CPU a chance to enter
low-power states.
* Make the hint an inline function, the call overhead can be avoided.
Currently the default install prefix is $BUILD_ROOT/zig-cache,
but mixing cache and artifacts makes little sense. Instead make
$BUILD_ROOT/zig-out the default.
Should be good enough to unblock progress on the stage2 compiler.
Unifying this parser and the regular one (and perhaps rewrite it, #2207)
is left as an exercise for the reader.
* 25519: remove unused const, safeguard against unreduced scalars
No behavior change, but it makes the existing code better match
the forthcoming code for other curves.
Rename nonAdjacentForm() to slide(), remove an unneeded and
confusing constant, and do a reduction in slide() if 257 bits would
be required.
Note that in all the high-level functions, the top bit is always
cleared, so the reduction is never necessary. But since the low-level
functions are public, the check is a safe thing to have.
* 25519: make identityElement public, deprecate neutralElement
Also fix a few comments by the way.
This reverts commit 77cb45f59f7b37c316af1762298d6032e2b130b5.
Zig's error return traces will point to the return token if they
happen to occur, so having multiple return statements makes those
stack traces really helpful. This destroys debuggability.
* #8454 Fix for std.mem.replacementSize adjacent matches bug.
When two 'needle' values are adjacent in the 'input' slice, the size is not
counted correctly. The 2nd 'needle' value is not matched because the index is
incremented by one after changing the index to account for the first value.
The impact is the the size returned is incorrect, and could cause UB when this
amount is used to size of the buffer passed to std.mem.replace.
* Apply changes from PR review:
- Add assert checking that the needle is non-empty and doc for this.
- Add minimal test that an empty input works.
- Use testing.expectEqualStrings.
