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.
This is a very new tag used for HDR content. The only files I know that
use it are the jpegs on https://ccameron-chromium.github.io/hdr-jpeg/
But they have an invalid ICC creation date, so `icc` can't process them.
(Commenting out the check for that does allow to print them.)
If the CIPC tag is present, it takes precedence about the actual data
in the profile and from what I understand, the ICC profile is
basically ignored. See https://www.color.org/events/HDR_experts.xalter
for background, in particular
https://www.color.org/hdr/02-Luke_Wallis.pdf (but the other talks
are very interesting too).
(PNG also has a cICP chunk that's supposed to take precedence over
iCCP.)
Before 6490529ef7, all programs in the
SPECIAL_TARGETS list were built because they didn't have an
EXCLUDE_FROM_ALL property set.
That commit set the property for all targets, but because of this, the
minimal "Required" build configuration no longer built, as CMake failed
to rename every special target. Even the not built ones.
This commit makes the rename action run only if the executable exists,
which makes us build Serenity without the `install` utility, and also
by using the minimal configuration set. :^) :^)
I used this utility to check if the possible TGA images' cases for
different origins (explictly the Y origin) are generating the same
bitmap, as I felt that my eyes are not a good-enough measurement tool
for this kind of task.
This might be useful in the future for testing other implementations so
I rather have this nice utility in our codebase.
This utility when given a .tff font provides options for disassembling:
- The 'fpgm' table, this a program that's run once when the font is
loaded. It's used to define instructions and functions used by used
by other programs.
- The 'prep' table, this is a general program that's run when ever
the font size (or other properties) changes.
- And the programs associated with any individual glyph.
The disassembly is printed in a format that matches the examples from:
https://learn.microsoft.com/en-us/typography/opentype/spec/tt_instructions
I'm mainly adding this because I think it's neat to be able to look
at these things, and think it'll be helpful for debugging an
interpreter.
With this you can see that all of the LiberationSerif-XXX.tff fonts in
Serenity have these programs ready to go.
In order to debug WebServer and responses we can't handle yet, it's
beneficial to being able to see what we request and what we get back.
As a first measure, we just log URL, response code, reason phrase and
headers.
This utility essentially creates a filesystem sandbox for a specified
command, so it can be tested with only the unveiled paths the user
specifies beforehand.
This adds command line flags for WebDriver to pass its IPC socket path
(if running on Serenity) or its FD passing socket (if running elsewhere)
for the headless-browser to connect to.
This happens in two ways:
1. LibCore now has two new methods for creating Jails and attaching
processes to a Jail.
2. We introduce 3 new utilities - lsjails, jail-create and jails-attach,
which list jails, create jails and attach processes to a Jail,
respectively.
We previously had a lot of duplication (and mismatched settings) around
whether a target was "special" or not, although the only special thing
about it was that its name was a reserved keyword and therefore had to
be renamed later.
Fix that by mostly consolidating the different configuration paths and
then purging all duplicated linking libraries from the bottom of the
file.
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
Even though the toolchain implicitly links against -lc, it does not know
where it should get LibC from except for the sysroot. In the case of
Clang this causes it to pick up the LibC stub instead, which might be
slightly outdated and feature missing symbols.
This is currently not an issue that manifests because we pass through
the dependency on LibC and other libraries by accident, which causes
CMake to link against the LibC target (instead of just the library),
and thus points the linker at the build output directory.
Since we are looking to fix that in the upcoming commits, let's make
sure that everything will still be able to find the proper LibC first.
This adds the `nologin` application to the system. This application
will look for `/etc/nologin`. If it is present, it will display the
message in the file. Otherwise, it will display an error about the
current account being unavailable.
Remove the Corrosion dependency, and use the now-builtin
add_jakt_executable function from the Jakt install rules to build our
example application.
By using find_package(Jakt), we now have to set ENABLE_JAKT manually on
both serenity and Lagom at the same time, so the preferred method to do
this for now is:
cmake -B Build/superbuild<arch><toolchain> \
-S Meta/CMake/Superbuild \
-DENABLE_JAKT=ON \
-DJAKT_SOURCE_DIR=/path/to/jakt
Where omitting JAKT_SOURCE_DIR will still pull from the main branch of
SerenityOS/jakt. This can be done after runing Meta/serenity.sh run.
Currently, LibUnicodeData contains the generated UCD and CLDR data. Move
the UCD data to the main LibUnicode library, and rename LibUnicodeData
to LibLocaleData. This is another prepatory change to migrate to
LibLocale.
This short-lived utility was essential when we had to use the ioctl
interface to fetch the EDID from a DisplayConnector, but now that we can
simply read it from SysFS, this utility is no longer needed and can be
removed.
This new command allows you to run any command with an initial set
of pledge promises.
Note that dynamically linked executables won't be able to bootstrap
without at least "stdio rpath prot_exec".
Inspired by http://justine.lol/pledge/ :^)
With this, the headless browser can now connect to the web.
Thanks a lot to Ali and Sin-ack for their help with this!
