Fonts on Windows are stored only in %WINDIR%\Fonts and
%LOCALAPPDATA%\Microsoft\Windows\Fonts, see https://stackoverflow.com/a/67078786
And system_data_directories() is not implemented on Windows yet.
A couple of reasons:
- Origin's Host (when in the tuple state) can't be null
- There's an "empty host" concept in the spec which is NOT the same as a
null Host, and that was confusing me.
size >> 31 >> 1 is used instead of size >> 32 to support 32-bit Windows
(size_t is 32 bit there, and you cannot shift 32-bit value by 32 bits
on x86)
This is equivalent to sizeof(size) == 4 ? 0 : size >> 32
Windows doesn't have a concept of zombie children, hence:
* `disown` not needed
* we need a process handle because otherwise if the process have ended
by the time `wait_for_termination` is called
its pid may be reassigned to other process
Fixes a bug when https://wpt.live/css/CSS2/positioning/abspos-001.xht
saved as file fails because we incorrectly recognized its MIME type
as HTML, leading to incorrect self-closing tag handling and thus
incorrect rendering.
The inline capacity on ThreadEventQueue::Private::queued_events caused
us to reserve (and importantly, not initialize!) 2 KiB of stack memory
when entering ThreadEventQueue::process().
This was causing any leftover pointers to GC-allocated objects within
that memory range to keep those objects alive, even when all other
references were gone.
Problem:
- Many constructors are defined as `{}` rather than using the ` =
default` compiler-provided constructor.
- Some types provide an implicit conversion operator from `nullptr_t`
instead of requiring the caller to default construct. This violates
the C++ Core Guidelines suggestion to declare single-argument
constructors explicit
(https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c46-by-default-declare-single-argument-constructors-explicit).
Solution:
- Change default constructors to use the compiler-provided default
constructor.
- Remove implicit conversion operators from `nullptr_t` and change
usage to enforce type consistency without conversion.
Problem:
- The implementation of `find` is coupled to the implementation of `Vector`.
- `Vector::find` takes the predicate by value which might be expensive.
Solution:
- Decouple the implementation of `find` from `Vector` by using a
generic `find` algorithm.
- Change the name of `find` with a predicate to `find_if` so that a
binding reference can be used and the predicate can be forwarded to
avoid copies.
- Change all the `find(pred)` call sites to use `find_if`.
This avoids unintentionally adding a newline character at the end of
user passwords when they are set using passwd(1).
I also fixed these two issues:
- The return value of getline() was being saved in an `int` variable
instead of in a `ssize_t` variable; I replaced the `int` keyword with
`auto` to fix this issue.
- Prior to this patch, get_password() could potentially return
tcsetattr()'s errno instead of getline()'s errno in case of an error.
We now make sure it always returns the right errno in case of an error.
This was very obviously racy and would only succeed if we already own
the socket anyway. (And if we do, we can bind to it without unlinking!)
Work towards #4876.
This doesn't solve half of the problems with /tmp/rpc, but this way we
can at least make it sticky instead of having it fully world-writable
and owned by whoever was the first to bind an RPC socket.
