I've added these three functions to all switches except NetBSD, because I don't know what the function is named there. I've even added it on the .windows switch since all the posix functions seem to be there anyways.
It turns out the code was not ported correctly from C and produced wrong
results for negative input values. As a bonus fix the NaN codepath by
adding yet another missing piece of code.
Spotted in #9047
The documentation (e.g. `man 7 rtnetlink`) states that ifi_change "is reserved for future use and should be always set to 0xFFFFFFFF". This is no longer true, even though the text hasn't been updated.
Since v0.23 release of Wasmtime, if we want to iterate a directory
Y then directory Y needed to have been granted `fd_readdir` right.
However, it is now also required for directory X to carry `fd_readdir`
right, and so on, up-chain all the way until we reach the preopen
(which possesses all rights by default).
This caused problems for us since our libstd implementation is more
fine-grained and allowed for parent dirs not to carry the right while
allow for iterating on its children. My proposal here is to always
grant `fd_readdir` right as part of
`std.fs.Dir.OpenDirOptions.access_sub_paths`. This seems to be the
approach taken by Rust also, plus we should be justified to take this
approach since WASI is experimental and snapshot1 will be discontinued
eventually and replaced with a new approach to access management
that will require a complete rewrite of our libstd anyhow.
Add two helpers to ensure people won't ignore some edge cases such as
pointers overflowing the address space.
Also fix#8924 to some degree, the amount of unchecked alignForward is
still scary.
* std: Better handing of POLLHUP in ChildProcess
Upon hitting the EOF condition there are two main differences between
how Linux and the *BSD-derived systems behave: the former sets POLLHUP
and POLLIN and, after reading any residual data, only POLLHUP remains
set. The latter signal the EOF condition by setting both flags thus
requiring some extra checks to determine if the stream is "done".
DragonFly workaround/hack for POLLHUP is no longer required.
Closes#8969
- hash/eql functions moved into a Context object
- *Context functions pass an explicit context
- *Adapted functions pass specialized keys and contexts
- new getPtr() function returns a pointer to value
- remove functions renamed to fetchRemove
- new remove functions return bool
- removeAssertDiscard deleted, use assert(remove(...)) instead
- Keys and values are stored in separate arrays
- Entry is now {*K, *V}, the new KV is {K, V}
- BufSet/BufMap functions renamed to match other set/map types
- fixed iterating-while-modifying bug in src/link/C.zig
