reads on eg. connected TCP sockets can fail with ETIMEDOUT, and ENOTCONN
happens eg. if you try to read a TCP socket that has not been connected
yet.
interestingly read() was already handling CONNRESET & TIMEDOUT, but
readv(), pread(), and preadv() were somewhat inconsistent.
This duplicates the source file string (as is done in other places such
as `addAssemblyFile()`) in order to prevent a segfault when the supplied
string is freed by the caller. This is still seen when the caller makes
use of a defer statement.
This reverts commit 8b10970836480a43a3bbb1276cb258c2a8b613f2.
This implementation has the following problems:
* It does not provide context to the less than function. This will be an
API break in order to fix.
* It uses recursion, causing unbounded stack memory usage - likely
depending on user input, which is extra problematic.
* Sorting linked lists is generally an inefficient operation;
encouraging it by having a standard library function for it may
lead to suboptimal software being written in Zig.
Furthermore, there is almost no benefit to providing a sort function as
a method, when a third party implementation can easily be passed a
linked list to then be sorted.
A parameter like this is not always optional, even if that is
usually implied. SPIR-V tools fail to parse a module with an
OpLoopMerge instruction where the loop control parameter is
left out.
Also remove the TODO--it was added in fd067fbe8b14c445ed764da15fff5163156126df, but the current code no longer used that workaround, so this TODO didn't seem relevant anymore.
* move std.atomic.Atomic to std.atomic.Value
* fix incorrect argument order passed to testing.expectEqual
* make the functions be a thin wrapper over the atomic builtins and
stick to the naming conventions.
* remove pointless functions loadUnchecked and storeUnchecked. Instead,
name the field `raw` instead of `value` (which is redundant with the
type name).
* simplify the tests by not passing every possible combination. Many
cases were iterating over every possible combinations but then not
even using the for loop element value!
* remove the redundant compile errors which are already implemented by
the language itself.
* remove dead x86 inline assembly. this should be implemented in the
language if at all.
This was originally supposed to be a lock-free queue, but I gave up on
that and made it be a thread-safe queue instead.
Putting the mutex directly inside the queue data structure makes it
non-composeable. Instead, the recommendation is to use a normal queue
protected by an external mutex.
