These changes are compatible with clang-format 16 and will be mandatory
when we eventually bump clang-format version. So, since there are no
real downsides, let's commit them now.
Previously, the cookie date validation did not validate days in the
context of the month and year, resulting in dates that do not exist to
be successfully parsed (e.g. February 31st). We now validate that the
day does not exceed the number of days for the given month and year,
taking leap years into account.
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:
```
Optional<I> opt;
if constexpr (IsSigned<I>)
opt = view.to_int<I>();
else
opt = view.to_uint<I>();
```
For us.
The main goal here however is to have a single generic number conversion
API between all of the String classes.
This is a clear sign that they want to use a UnixDateTime instead.
This also adds support for placing durations and date times into SQL
databases via their millisecond offset to UTC.
That's what this class really is; in fact that's what the first line of
the comment says it is.
This commit does not rename the main files, since those will contain
other time-related classes in a little bit.
We are currently converting parsed expiry times to local time, whereas
the RFC dictates we parse them as UTC. When expiring cookies, we must
also use the current UTC time to compare against the cookies' expiry
times.
In doing so, this removes all uses of the Encoder's stream operator,
except for where it is currently still used in the generated IPC code.
So the stream operator currently discards any errors, which is the
existing behavior. A subsequent commit will propagate the errors.
Currently, the generated IPC decoders will default-construct the type to
be decoded, then pass that value by reference to the concrete decoder.
This, of course, requires that the type is default-constructible. This
was an issue for decoding Variants, which had to require the first type
in the Variant list is Empty, to ensure it is default constructible.
Further, this made it possible for values to become uninitialized in
user-defined decoders.
This patch makes the decoder interface such that the concrete decoders
themselves contruct the decoded type upon return from the decoder. To do
so, the default decoders in IPC::Decoder had to be moved to the IPC
namespace scope, as these decoders are now specializations instead of
overloaded methods (C++ requires specializations to be in a namespace
scope).
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
In order to avoid the base encode/decode methods from being used (and
failing a static assertion), we must be sure to declare/define the
custom type implementations as template specializations.
After this, LibIPC is no longer sensitive to include order.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Problem:
- New `all_of` implementation takes the entire container so the user
does not need to pass explicit begin/end iterators. This is unused
except is in tests.
Solution:
- Make use of the new and more user-friendly version where possible.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.

To protect the main Browser process against nefarious cookies, parse the
cookies out-of-process and then send the parsed result over IPC to the
main process. This way, if the cookie parser blows up, only that tab
will be affected.
To implement the HttpOnly attribute, the CookieJar needs to know where a
request originated from. Namely, it needs to distinguish between HTTP /
non-HTTP (i.e. JavaScript) requests. When the HttpOnly attribute is set,
requests from JavaScript are to be blocked.
This moves the cookie parsing steps out of CookieJar into their own file
inside LibWeb. It makes sense for the cookie structures to be in LibWeb
for a couple reasons:
1. There are some steps in the spec that will need to partially happen
from LibWeb, such as the HttpOnly attribute.
2. Parsing the cookie string will be safer if it happens in the OOP tab
rather than the main Browser process. Then if the parser blows up due
to a malformed cookie, only that tab will be affected.
3. Cookies in general are a Web concept not specific to a browser.
