RefPtr<Notifier> doesn't work quite like it appears to, since the notifier
is also a "child" of the socket, in Core::Object sense. Thus we have to both
remove it from the parent (socket) and drop the additional RefPtr<Notifier> for
it to actually go away.
A proper fix for this would be to untangle parent-child relashionship from
refcounting and inspectability.
This fixes use-after-close of client file descriptors in IPC servers.
.. and make travis run it.
I renamed check-license-headers.sh to check-style.sh and expanded it so
that it now also checks for the presence of "#pragma once" in .h files.
It also checks the presence of a (single) blank line above and below the
"#pragma once" line.
I also added "#pragma once" to all the files that need it: even the ones
we are not check.
I also added/removed blank lines in order to make the script not fail.
I also ran clang-format on the files I modified.
And move canonicalized_path() to a static method on LexicalPath.
This is to make it clear that FileSystemPath/canonicalized_path() only
perform *lexical* canonicalization.
Lagom now builds under macOS. Only two minor adjustments were required:
* LibCore TCP/UDP code can't use `SOCK_{NONBLOCK,CLOEXEC}` on macOS,
use ioctl() and fcntl() instead
* LibJS `Heap` code pthread usage ported to MacOS
The "ready to write" notifier we set up in generic socket connection is
really only meant to detect a successful connection. Once we have a TCP
connection, for example, it will fire on every event loop iteration.
This was causing IRC Client to max out the CPU by getting this no-op
notifier callback over and over.
Since this was only used by TLSv12, I changed that code to create its
own notifier instead. It might be possible to improve TLS performance
by only processing writes when actually needed, but I didn't look very
closely at that for this patch. :^)
This fixes an issue where continuously posting new events to the queue
would keep the event loop saturated, causing it to ignore notifiers.
Since notifiers are part of the big select(), we always have to call
wait_for_events() even if there are pending events. We're already smart
enough to select() without a timeout if we already have pending events.
Moves DirectoryServices out of LibCore (because we need to link with
LibIPC), renames it Desktop::Launcher (because Desktop::DesktopServices
doesn't scan right) and ports it to use the LaunchServer which is now
responsible for starting programs for a file.
Prior to this commit, we would (re-)allocate the output buffer aligned
to 1024 bytes, but never trim it down to size, which caused
Gzip::decompress to return uninitialised data.
`read_bool_entry()` can now interpret both integers (1 or 0) and
Boolean strings ("true" or "false") in configuration files.
All values other than "1" or "true" are considered false.
It was impractical to return a RefPtr<File> since that left us no way
to extract the error string. This is usually needed for the UI, so the
old static open() got basically no use.
The event that triggered the exit from an inner event loop would always
get re-delivered in the outer event loop due to a silly off-by-one
mistake when transferring pending events between loops.
This helper opens a file with a given name, mode and permissions and
returns it in a RefPtr<File>. I think this will be a bit nicer to use
than having to go through Core::File::construct() every time.
The kernel was already using the UDP prefix, and the TCP LibCore classes
are also uppercased. Let's rename for consistency.
Also order the LibCore Makefile alphabetically, because everywhere else
seems to be doing that :)
