This will ensure that we don't leak any memory while playing back
audio.
There is an expectation value in the test that is only set to true when
PulseAudio is present for the moment. When any new implementation is
added for other libraries/platforms, we should hopefully get a CI
failure due to unexpected success in creating the `PlaybackStream`.
To ensure that we clean up our PulseAudio connection whenever audio
output is not needed, add `PulseAudioContext::weak_instance()` to allow
us to check whether an instance exists without creating one.
This adds an abstract `Audio::PlaybackStream` class to allow cross-
platform audio playback to be done in an opaque manner by applications
in both Serenity and Lagom.
Currently, the only supported audio API is PulseAudio, but a Serenity
implementation should be added shortly as well.
Since the existing Promise class is designed with deferred tasks on the
main thread only, we need a new class that will ensure we can handle
promises that are resolved/rejected off the main thread.
This new class ensures that the callbacks are only called on the same
thread that the promise is fulfilled from. If the callbacks are not set
before the thread tries to fulfill the promise, it will spin until they
are so that they will run on that thread.
LibTLS still can't access many parts of the web, so let's hide this
behind a flag (with all the plumbing that entails).
Hopefully this can encourage folks to improve LibTLS's algorithm support
:^).
Currently, the `isobmff` utility will only print the media file type
info from the FileTypeBox (major brand and compatible brands), as well
as the names and sizes of top-level boxes.
The AST interpreter is still available behind a new `--ast` flag.
We switch to testing with bytecode in the big run-tests battery on
SerenityOS. Lagom CI continues running both AST and BC.
Using the cross-page links, we can generate a directed graph showing the
topology of which pages refer to other pages. This is not just for fun:
the links show how often a page is linked (since links are not
deduplicated on purpose), which pairs of pages only have links in one
direction (where a link in the other direction may be useful), which
groups of closely-interlinked pages exist, and which pages have few or
no links to other pages.
The EXTRA_MARKDOWN_CHECK_ARGS argument to the check-markdown script can
be used to inject the -g flag for generating the graph on all manpages.
This utility will learn tricks such as extracting images from PDFs and
dumping tables from PDFs so that we can create code from specs.
It also allows testing LibPDF things in lagom, and allows testing
reading large amounts of PDFs using a shell script.
This was meant to be a temporary unit testuntil we could run test-js
in bytecode mode. This has been possible for a long time now, so let's
remove the unnecessary extra program.
On macOS, CMake incorrectly tries to add and/or remove rpaths from files
that it has already processed when it performs installation. Setting the
rpaths during the build process ensures that they are only set once, and
as a bonus, makes installation slightly more performant.
Fixes#10055.
This will make it a lot easier to understand what went wrong, especially
when the failure occurs on CI but not at home.
And of course, use LibDiff to generate the diff! :^)
It does not make sense to test known-working code that is deprecated and
in the process of being removed. Also, this test becomes too cumbersome
to write without using read_all or line iteration in some form, and
migrating the test is just silly.
For the most part no behavior change, except that we now pass
-Wno-implicit-const-int-float-conversion and -Wno-literal-suffix
only to clang and gcc each in both lagom and serenity builds,
while we previously passed them to both in lagom builds (and
passed them to one each in serenity builds). The former is
a clang flag, the latter a gcc flag, but since we also use
-Wno-unknown-warning-option it doesn't really matter.
This makes it easy to compare the performance of Serenity's
deflate implementation to the host system implementation.
On my M1 Max MBP:
% time gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
takes between 0.064s and 0.082s.
% time Build/lagom/gunzip -c \
/Users/thakis/Downloads/trace_bug.json.gz > /dev/null
on the other hand takes 4 seconds.
(That .gz file is a 5.8M file -- the largest .gz file that happend to be
in my Downloads folder.)
We can always read the basic format information (sample rate, bit depth,
etc.), but we will also print artist, album, and title if available in
the metadata.
headless-browser currently uses its own PageClient to load web pages
in-process. Due to this, it also needs to set up a whole bunch of other
objects needed to run LibWeb, e.g. image decoders, request servers, etc.
This changes headless-browser to instead implement a WebView to launch
WebContent out-of-process. This implementation is almost entirely empty,
but can be filled in as-needed. For example, we may want to print
JavaScript console messages.
At the moment, all it can do is read all image formats that LibGfx can
read and save to any image format that LibGfx can write (currently bmp,
png, qoi).
Currently, it drops all image metadata (including color profiles).
Over time, this could learn tricks like keeping color profiles,
converting an image to a different color profile, cropping out a part of
an image, and so on.
Imported functions in Wasm may throw JS exceptions, and we need to
preserve these exceptions so we can pass them to the calling JS code.
This also adds a `assert_wasm_result()` API to Result for cases where
only Wasm traps or values are expected (e.g. internal uses) to avoid
making LibWasm (pointlessly) handle JS exceptions that will never show
up in reality.
Make sure that we set SERENITY_SOURCE_DIR in ctest, and make sure to
pass the test root to the CI job.
More overhaul of test-js 'test root' finding is needed however.
Some tests, such as those under LibGL, try to load shared libraries at
runtime which are stored in Build/lagom. Because all tests' working
directory is that of their CMakeLists.txt file, they fail to find those
shared libraries at runtime.
Set LD_LIBRARY_PATH to Build/lagom so the tests may find the shared
libraries. This fixes, for example, both of these commands:
./Meta/serenity.sh test lagom TestAPI
./Meta/serenity.sh run lagom TestAPI
When we call add_test() from each test's CMakeLists.txt, we specify the
working directory to be that of the CMakeList.txt file itself. Create a
property to store that directory and reference it when run-lagom-target
is invoked by serenity.sh.
Note that for non-test Lagom targets which do not set this property, the
working directory will be Build/lagom (because the property will be the
empty string, which CMake resolves relative to the current build path).
They can be run using
Meta/serenity.sh test lagom TestFontHandling
which will build _all_ test binaries and then run TestFontHandling.
There's also
Meta/serenity.sh run lagom TestFontHandling
which will build just TestFontHandling and run it, but currently
in a way that it doesn't pass.
Finally, manually doing
Meta/serenity.sh build lagom TestFontHandling
followed by
(cd Tests/LibGfx; ../../Build/lagom/Tests/LibGfx/TestFontHandling)
will build and then run just that one test in a way that makes the test
pass.
After 5ac57f9, we could no longer run "serenity.sh run lagom TestString"
because the TestString binary now lives in a subdirectory under
Build/lagom. Thus the existing method of running "$BUILD_DIR/TestString"
could not work.
This adds a "run-lagom-target" custom target to Lagom, to run a command
and pass arguments to that invocation. It turns out there really isn't a
"pretty" way of doing this with CMake or Ninja. But we can pass these as
environment variables for CMake to interpret. We just must be careful to
massage arguments into a CMake list.
...mostly.
This creates and uses an override for the `serenity_test()` function, so
that Lagom can make use of the existing `Tests/LibFoo/CMakeLists.txt`
files instead of having to GLOB for test source files and manually copy
any data files.
Some GLOBs remain but this is most of them.

The macOS FileWatcher depends on macOS dispatch queues, which run on a
different thread than the Core::EventLoop. This implementation handles
filesystem events on its dispatch queue, then forwards the event back to
the main Core::EventLoop for notifying the FileWatcher owner.
This implements FileWatcher using inotify filesystem events. Serenity's
InodeWatcher is remarkably similar to inotify, so this is almost an
identical implementation.
The existing TestLibCoreFileWatcher test is added to Lagom (currently
just for Linux).
This does not implement BlockingFileWatcher as that is currently not
used anywhere but on Serenity.
