* extract http protocol into protocol.zig, as it is shared between client and server
* coalesce Request and Response back into Client.zig, they don't contain
any large chunks of code anymore
* http.Server is implemented as basic as possible, a simple example below:
```zig
fn handler(res: *Server.Response) !void {
while (true) {
defer res.reset();
try res.waitForCompleteHead();
res.headers.transfer_encoding = .{ .content_length = 14 };
res.headers.connection = res.request.headers.connection;
try res.sendResponseHead();
_ = try res.write("Hello, World!\n");
if (res.connection.closing) break;
}
}
pub fn main() !void {
var server = Server.init(std.heap.page_allocator, .{ .reuse_address = true });
defer server.deinit();
try server.listen(try net.Address.parseIp("127.0.0.1", 8080));
while (true) {
const res = try server.accept(.{ .dynamic = 8192 });
const thread = try std.Thread.spawn(.{}, handler, .{res});
thread.detach();
}
}
```
* GPA: Catch invalid frees
Fix#14791: Catch cases where an invalid slice is passed to free().
This was silently ignored before but now logs an error. This change
uses a AutoHashMap to keep track of the sizes which seems to be an
overkill but seems like the easiest way to catch these errors.
* GPA: Add wrong alignment checks to free/resize
Implement @Inkryption's suggestion to catch free/resize with the wrong
alignment. I also changed the naming to match large allocations.
Also clean up parsing of linker args - reuse `ArgsIterator`.
In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.
MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.
- `fcntl` was renamed to `fcntl64` in glibc 2.28 (see #9485)
- `res_{,n}{search,query,querydomain}` became "their own" symbols since
glibc 2.34: they were prefixed with `__` before.
This PR makes it possible to use `fcntl` with glibc 2.27 or older and
the `res_*` functions with glibc 2.33 or older.
These patches will become redundant with universal-headers and can be
dropped. But we have to do with what we have now.
Closes#9485
