Instead of downloading nearly 20 files individually, we can download a
single .zip file similar to how we download a single CLDR .zip. This is
to reduce the number of connections/downloads to/from unicode.org.
This adds the is_primitive() method as described in the Web IDL
specification. is_primitive() returns true if the type is a bigint,
boolean or numeric type.
This is in Tests/LibTTF instead of Tests/LibGfx because Tests/LibGfx
depends on serenity's file system layout and can't run in lagom,
but this new test runs just fine in lagom.
Now that clang-format-14 ubuntu packages are available, it's time to
finally upgrade our clang-format version. This version brings with it
a bunch of useful features with const-placement being the most notable.
These will be enabled in the following commits.
4k logical blocks are better for block devices in QEMU as they align
with the underlying filesystem which typically has 4k logical blocks
such as our EXT2 filesystem.
This is an editorial change in the Intl spec. See:
https://github.com/tc39/ecma402/commit/087995chttps://github.com/tc39/ecma402/commit/233d29c
This also adds a missing spec link for the sanctioned units and fixes a
broken spec link for IsSanctionedSingleUnitIdentifier. In LibUnicode,
the NumberFormat generator is updated to use the constexpr helper to
retrieve sanctioned units.
WASM_SPEC_TEST_TAR_PATH actually refers to a tarball that has already
been decompressed with gzip, so running `tar -xzf` on it fails.
I introduced this mistake in 66582a875f.
There is no need to keep an intermediary plain .tar file around, we can
pass the WASM_SPEC_TEST_GZ_PATH .tar.gz directly to `tar -xzf`.
Currently this can parse XML and resolve external resources/references,
and read a DTD (but not apply or verify its rules).
That's good enough for _most_ XHTML documents as the HTML 5 spec
enforces its own rules about document well-formedness, and does not make
use of XML DTDs (aside from a list of predefined entities).
An accompanying `xml` utility is provided that can read and dump XML
documents, and can also run the XML conformance test suite.
This does a few things in total:
* Ports the IPC-compiler to LibMain
* Extract some compiler steps into separate functions
* Minify some appends to use appendln (or appendff in the case of
StringBuilder)
This reduces the clang-tidies maximum cognitive-complexity score for
this file from 325 to under 100.
While GNU tar automatically detects the used compression algorithm,
POSIX requires that we specify -z if the tarball is compressed with
gzip.
Fixes a build error on OpenBSD.
We're now able to detect all the regular CPUID feature flags from
ECX/EDX for EAX=1 :^)
None of the new ones are being used for anything yet, but they will show
up in /proc/cpuinfo and subsequently lscpu and SystemMonitor.
Note that I replaced the periods from the SSE 4.1 and 4.2 instructions
with underscores, which matches the internal enum names, Linux's
/proc/cpuinfo and the general pattern of replacing special characters
with underscores to limit feature names to [a-z0-9_].
The enum member stringification has been moved to a new function for
better re-usability and to avoid cluttering up Processor.cpp.
We did already have range checking for the `<integer>` and `<number>`
types, but this patch adds this functionality to all numeric types
(dimensions and percentages).
The syntax in Properties.json is taken from the spec:
https://www.w3.org/TR/css-values-3/#numeric-ranges
eg, `length [0,∞]` defines that a Length is allowed as long as it has a
positive value.
The implementation here allows for any number to be the positive or
negative limit, even though only 0 and positive/negative infinity are
meaningful values without a unit.
This appears to be a remnant from the earlier HeaderCheck revisions,
where CMakeLists.txt was automatically generated.
Now that a (static) copy of CMakeLists.txt is checked in, this file
doesn't have any effect anymore.
This is a bit strange in the IDL syntax, but e.g., in HTMLSelectElement,
we have (simplified):
undefined add(optional (HTMLElement or long)? before = null)
This could instead become:
undefined add(optional (HTMLElement or long) before)
This change generates code for the former as if it were the latter.
I came across some websites that change an elements CSS "opacity" in
their :hover selectors. That caused us to relayout on hover, which we'd
like to avoid.
With this patch, we now check if a property only affects the stacking
context tree, and if nothing layout-affecting has changed, we only
invalidate the stacking context tree, causing it to be rebuilt on next
paint or hit test.
This makes :hover { opacity: ... } rules much faster. :^)
run.sh builds i686 by default, and the aarch64 port of serenity
isn't very far along yet.
Without this change, `run.sh` without arguments unceremoniously
fails with:
[0/1] cd .../serenity/Build/i686 && /usr...
ENITY_ARCH=i686 /home/thakis/src/serenity/Meta/run.sh
qemu-system-i386: invalid accelerator kvm
That's because /dev/kvm exists, but that's no good on a non-intel host.
When building on an arm host system, char defaults to unsigned,
leading to errors such as:
serenity/AK/StringBuilder.cpp:198:20:
error: comparison is always true due to limited range of data type
[-Werror=type-limits]
198 | if (ch >= 0 && ch <= 0x1f)
|
Building with -fsigned-char makes things work like on Intel, and
it's what we already do in Kernel/CMakeLists.txt for the same reasons.
We have seen some cases where the build fails for folks, and they are
missing unzip/tar/gzip etc. We can catch some of these in CMake itself,
so lets make sure to handle that uniformly across the build system.
The REQUIRED flag to `find_program` was only added on in CMake 3.18 and
above, so we can't rely on that to actually halt the program execution.
With regular builds, the generated IPC headers exist inside the Build
directory. The path Userland/Services under the build directory is
added to the include path.
For in-system builds the IPC headers are installed at /usr/include/.
To support this, we add /usr/include/Userland/Services to the build path
when building from Hack Studio.

Day and month name constants are defined in numerous places. This
pulls them together into a single place and eliminates the
duplication. It also ensures they are `constexpr`.
This patch adds CSS::property_affects_layout(PropertyID) which tells us
whether a CSS property would affect layout if it were changed.
This will be used to avoid unnecessary relayout work when something
changes that really only requires us to repaint the page.
To mark a property as not affecting layout, set "affects-layout" to
false in the corresponding Properties.json entry. Note that all
properties affect layout by default.
...and let LibWasm do the validation instead of removing the test when a
module is invalid.
Also, one of the tests has an integer literal starting with zero, so
account for this to make it not fail :^)
Since we want to store an initial value for every CSS::PropertyID,
it's pretty silly to use a HashMap when we can use an Array.
This takes the function from ~2.8% when mousing around on GitHub all the
way down to ~0.6%. :^)
As there is no need for a Prekernel on aarch64, the Prekernel code was
moved into Kernel itself. The functionality remains the same.
SERENITY_KERNEL_AND_INITRD in run.sh specifies a kernel and an inital
ramdisk to be used by the emulator. This is needed because aarch64
does not need a Prekernel and the other ones do.
These work differently from how we validate StyleValues. There, we parse
a StyleValue from the CSS, and then see if it is allowed in the
property. That causes problems when the syntax is ambiguous - for
example, `0` can be a number or a Length.
Here instead, we ask what kinds of value are allowed for a
media-feature, and then only attempt to parse those kinds of value.
This makes the ambiguity problem go away. :^)
Each media-feature in the spec only accepts one type of value, and/or
some identifiers. This makes the switch statements for the type a bit
excessive, but the spec does not *require* that only one type is
allowed, so this is more future-proof.
This works largely the same as the PropertyID and ValueID generators,
but using LibMain, Core::Stream, and TRY().
Rather than have a MediaFeatureID::Invalid, I decided to return an
Optional. We'll see if that turns out better or not. :^)
This patch adds NodeIterator (created via Document.createNodeIterator())
which allows you to iterate through all the nodes in a subtree while
filtering with a provided NodeFilter callback along the way.
This first cut implements the full API, but does not yet handle nodes
being removed from the document while referenced by the iterator. That
will be done in a subsequent patch.
This directory has to be writable if we want to install ports that have
been built inside Serenity. It's owned by root anyway, so having it be
read-only does not provide many security benefits.
Because of ninja's default behavior of using all processors this gave
the correct behaviour because MAKEJOBS was empty. However this meant
that the processor count was printed to stderr when building.
This initial version lays down the basic foundation of IDL overload
resolution, but much of it will have to be replaced with the actual IDL
overload resolution algorithms once we start implementing more complex
IDL overloading scenarios.
The microvm machine type is a modern tool for kernel and firmware
developers to test their software against features like FDTs, second
IOAPIC, lack of legacy devices by default, the ability of using PCIe
without using PCI x86 IO ports, etc.
We can boot into such machine but we are limited in the functionality we
support currently for this type of virtual machine.
The ISA-PC machine type provides no PCI bus support, no IOAPIC support
and other modern PC features of our generation.
This is mainly a good environment for testing abstractions in the kernel
space, and can help with improving on them for the sake of porting the
OS to other chipsets and CPU architectures.
We use the environment variable SERENITY_SOURCE_DIR to resolve and check
icon links. This is a bit inconvenient as SERENITY_SOURCE_DIR needs to
be set correctly before invoking the markdown checker, but as we use it
through the check-markdown script anyways, I think it's not a problem.
Previously we added it only if spice was available, but it's possible to
build qemu with --disable-spice --enable-spice-protocol, which provides
qemu-vdagent but no spicevmc. In such case we still configured
qemu-vdagent to use "vdagent" device, but never actually defined it, so
the qemu-vdagent was never working.
This allows us to fuzz the generated unicode and timezone database
helpers, and to fuzz things like LibJS using Fuzzilli to get proper
coverage of our unicode handling code.
Update the Azure CI to use the new two-stage build as well, and cleanup
some unused CMake options there.
According to its manpage genext2fs tries to create the file system with
as few inodes as possible. This causes SerenityOS to fail at boot time
when creating temporary files.
We now pass along the toolchain type to all subcommands. This ensures
that gdb will load the correct debug information for kernels compiled
with Clang, and the following warning won't appear with the GNU
toolchain:
> WARNING: unknown toolchain 'gdb'. Defaulting to GNU.
> Valid values are 'Clang', 'GNU' (default)
WebSockets got moved from the HTML standard to their own, the new
WebSockets Standard (https://websockets.spec.whatwg.org).
Move the IDL file and implementation into a new WebSockets directory and
C++ namespace accordingly.
The single 4000-line WrapperGenerator.cpp file was proving to be a pain
to hack, and was filled with spaghetti, split it into a bunch of files
to lessen the impact of the spaghetti.
Also refactor the whole parser to use a class instead of a giant
function with a million lambdas.
I've attempted to handle the errors gracefully where it was clear how to
do so, and simple, but a lot of this was just adding
`release_value_but_fixme_should_propagate_errors()` in places.
I can't imagine how this happened, but it seems we've managed to
conflate the "event listener" and "EventListener" concepts from the DOM
specification in some parts of the code.
We previously had two things:
- DOM::EventListener
- DOM::EventTarget::EventListenerRegistration
DOM::EventListener was roughly the "EventListener" IDL type,
and DOM::EventTarget::EventListenerRegistration was roughly the "event
listener" concept. However, they were used interchangeably (and
incorrectly!) in many places.
After this patch, we now have:
- DOM::IDLEventListener
- DOM::DOMEventListener
DOM::IDLEventListener is the "EventListener" IDL type,
and DOM::DOMEventListener is the "event listener" concept.
This patch also updates the addEventListener() and removeEventListener()
functions to follow the spec more closely, along with the "inner invoke"
function in our EventDispatcher.
We no longer include all the things, so each generated IDL file only
depends on the things it actually needs now.
A possible downside is that all IDL files have to explicitly import
their dependencies.
Note that non-IDL dependencies still remain and are injected into all
generated files, this can be resolved later if desired by allowing IDL
files to import headers.
BCP 47 will be the single source of truth for known calendar and number
system keywords, and their aliases (e.g. "gregory" is an alias for
"gregorian"). Move the generation of available keywords to where we
parse the BCP 47 data, so that hard-coded aliases may be removed from
other generators.
We have a fair amount of hard-coded keywords / aliases that can now be
replaced with real data from BCP 47. As a result, the also changes the
awkward way we were previously generating keys. Before, we were more or
less generating keywords as a CSV list of keys, e.g. for the "nu" key,
we'd generate "latn,arab,grek" (ordered by locale preference). Then at
runtime, we'd split on the comma. We now just generate spans of keywords
directly.
This package was originally meant to be included in CLDR version 40, but
was missed in their release scripts. This has been resolved:
https://unicode-org.atlassian.net/browse/CLDR-15158
Unfortunately, the CLDR was re-released with the same version number. So
to bust the build's CLDR cache, change the "version" used to detect that
we need to redownload the CLDR.
This is no longer needed as BrowsingContextContainer::content_document()
now does the right thing, and HTMLIFrameElement.contentDocument is the
only user of this attribute. Let's not invent our own mechanisms for
things that are important to get right, like same origin comparisons.
The spec version of canonical_numeric_index_string is absurdly complex,
and ends up converting from a string to a number, and then back again
which is both slow and also requires a few allocations and a string
compare.
Instead this patch moves away from using Values to represent canonical
a canonical index. In most cases all we need to know is whether a
PropertyKey is an integer between 0 and 2^^32-2, which we already
compute when we construct a PropertyKey so the existing is_number()
check is sufficient.
The more expensive case is handling strings containing numbers that
don't roundtrip through string conversion. In most cases these turn
into regular string properties, but for TypedArray access these
property names are not treated as normal named properties.
TypedArrays treat these numeric properties as magic indexes that are
ignored on read and are not stored (but are evaluated) on assignment.
For that reason there's now a mode flag on canonical_numeric_index_string
so that only TypedArrays take the cost of the ToString round trip test.
In order to improve the performance of this path this patch includes
some early returns to avoid conversion in cases where we can quickly
know whether a property can round trip.
This adds a generator utility to read an entire file and parse it as a
JSON value. This is heavily used by the CLDR generators. The idea here
is to put the file reading details in the utility so that when we have a
good story for generically reading an entire stream in LibCore, we can
update the generators to use that by only touching this helper.
This also moves the open_file helper to the utility file. It's currently
a lambda redefined in each TZDB/Unicode generator. It used to display
the missing command line flag and other info local to each generator.
After switching to LibMain, it just returns a generic error message, and
is duplicated several times.
This reverts commit 3a184f7841.
This broke a number of test262 tests under "TypedArrayConstructors".
The issue is that the CanonicalNumericIndexString AO should not fail
for inputs like "1.1", despite them not being integral indices.
The spec version of canonical_numeric_index_string is absurdly complex,
and ends up converting from a string to a number, and then back again
which is both slow and also requires a few allocations and a string
compare.
Instead lets use the logic we already have as that is much more
efficient.
This improves performance of all non-numeric property names.
This initial implementation stubs out the WorkerGlobalScope,
WorkerLocation and WorkerNavigator classes. It doesn't take into account
all the things that actually need passed into the constructors for these
objects, nor the extra abstract operations that need to be performed on
them by the rest of the Browser infrastructure. However, it does create
bindings that compile and link :^)
This adds a CPack configuration to generate a release package for js(1).
Our current CMake requirement is 3.16, which doesn't have a great story
for automatically installing a binary target's library dependencies. If
we eventually require CMake 3.21 or above, we can remove the helper
.cmake file added here in lieu of RUNTIME_DEPENDENCIES.
This isn't perfect (especially the global object situation in
activate_event_handler), but I believe it's in a much more complete
state now :^)
This fixes the issue of crashing in prepare_for_ordinary_call with the
`i < m_size` crash, as it now uses the IDL callback functions which
requires the Environment Settings Object. The environment settings
object for the callback is fetched at the time the callback is created,
for example, WrapperGenerator gets the incumbent settings object for
the callback at the time of wrapping. This allows us to remove passing
in ScriptExecutionContext into EventTarget's constructor.
With this, we can now drop ScriptExecutionContext.
Since VM::exception() no longer exists this is now useless. All of these
calls to clear_exception were just to clear the VM state after some
(potentially) failed evaluation and did not use the exception itself.
Now that the GML formatter is both perserving comments and also mostly
agrees to the existing GML style, it can be used to auto-format all the
GML files in the system. This commit does not only contain the scripts
for running the formatting on CI and the pre-commit hook, but also
initially formats all the existing GML files so that the hook is
successfull.
Prefixes are very much a C thing which we don't need in C++. This commit
moves all GML-related classes in LibGUI into the GUI::GML namespace, a
change somewhat overdue.
QEMU crashes on M1 Macs when using `--accel hvf` option.
To solve this, detect the host's architecture and only add the
`--accel hvf` parameter if we are running on a "x86_64" machine.
This will allow "arm64" machines like M1 Macs to work correctly.
The CMakeLists.txt for Lagom contains a few libraries and executables
with X86-specific code. By excluding those libraries, Lagom builds
for macOS on Arm as well. The places are marked FIXME to be removed
when the libraries will build for Arm.
Under Debian `e2fsck` is found in `/sbin/` which does not match the
existing "version" the script currently uses (`/usr/sbin/e2fsck`
versus `/sbin/e2fsck`); therefore I added a simple `if` condition to
remedy the situation by verifying whether the original path exists or
not, so I can use the one Debian expects.
Special thanks goes to Tim Flynn a.k.a. `trflynn89` for his valuable
feedback.
While playing around with getting serenity to run on my main desktop
machine I wanted a way of easily updating my physical serenity
partition.
To use it you just need to:
- Create and format your local partition to ext4
- Set `SERENITY_TARGET_INSTALL_PARTITION` to the partition /dev path.
- Run the `install-native-partition` build target.
Example:
$ export SERENITY_TARGET_INSTALL_PARTITION=/dev/nvme1n1p3
$ cd serenity/Build/x86_64
$ ninja install-native-partition
Added the call to generate_available_values(), then realized it is the
exact same as the existing, manually written implementation. So let's
use the new utility.
Unlike other BCP47 keywords that we are parsing, these only appear in
the BCP47 XML file itself within the CLDR. The values are very simple
though, so just hard code them until the Unicode org re-releases the
CLDR with BCP47: https://unicode-org.atlassian.net/browse/CLDR-15158
This commit removes the usage of HashMap in Mutex, thereby making Mutex
be allocation-free.
In order to achieve this several simplifications were made to Mutex,
removing unused code-paths and extra VERIFYs:
* We no longer support 'upgrading' a shared lock holder to an
exclusive holder when it is the only shared holder and it did not
unlock the lock before relocking it as exclusive. NOTE: Unlike the
rest of these changes, this scenario is not VERIFY-able in an
allocation-free way, as a result the new LOCK_SHARED_UPGRADE_DEBUG
debug flag was added, this flag lets Mutex allocate in order to
detect such cases when debugging a deadlock.
* We no longer support checking if a Mutex is locked by the current
thread when the Mutex was not locked exclusively, the shared version
of this check was not used anywhere.
* We no longer support force unlocking/relocking a Mutex if the Mutex
was not locked exclusively, the shared version of these functions
was not used anywhere.
Previously, given a malformed IPC call declaration, where a parameter
does not have a name, the IPCCompiler would spin endlessly while
consuming more and more memory.
This is because it parses the parameter type incorrectly
(it consumes superfluous characters into the parameter type).
An example for such malformed declaration is:
tokens_info_result(Vector<GUI::AutocompleteProvider::TokenInfo>) =|
As a temporary fix, this adds VERIFY calls that would fail if we're at
EOF when parsing parameter names.
A real solution would be to parse C++ parameter types correctly.
LibCpp's Parser could be used for this task.
Relative-time format patterns are of one of two forms:
* Tensed - refer to the past or the future, e.g. "N years ago" or
"in N years".
* Numbered - refer to a specific numeric value, e.g. "in 1 year"
becomes "next year" and "in 0 years" becomes "this year".
In ECMA-402, tensed and numbered refer to the numeric formatting options
of "always" and "auto", respectively.
This sets up the generator plumbing to create the relative-time data
files. This data could probably be included in the date-time generator,
but that generator is large enough that I'd rather put this tangentially
related data in its own file.
Previously, we were breaking up digits into groups without regard for
the locale's minimumGroupingDigits value in the CLDR. This value is 1 in
most locales, but is 2 in locales such as pl-PL. What this means is that
in those locales, the group separator should only be inserted if the
thousands group has at least 2 digits. So 1000 is formatted as "1,000"
in en-US, but "1000" in pl-PL. And 10000 is "10,000" in en-US and
"10 000" in pl-PL.
This check isn't needed because download_file() will check if it exists
already before doing the download. Worse, it would prevent the generator
target from being defined if the file existed, which then made CMake not
realize the generated files were important and delete them.
After fixing the CMake file to use the correct paths, users may have had
to manually remove the existing downloaded pnp.ids.html for CMake to re-
run the generator. So this change renames the downloaded file to
pnp_ids.html to ensure everyone picks up that change without manual
intervention.
Code generators that generate their files for both Lagom and Serenity
have a blob in their CMake file like this:
set(TIME_ZONE_DATA_HEADER LibTimeZone/TimeZoneData.h)
set(TIME_ZONE_DATA_IMPLEMENTATION LibTimeZone/TimeZoneData.cpp)
set(TIME_ZONE_META_TARGET_PREFIX LibTimeZone_)
if (CMAKE_CURRENT_BINARY_DIR MATCHES ".*/LibTimeZone")
# Serenity build.
set(TIME_ZONE_DATA_HEADER TimeZoneData.h)
set(TIME_ZONE_DATA_IMPLEMENTATION TimeZoneData.cpp)
set(TIME_ZONE_META_TARGET_PREFIX "")
endif()
LibEDID generates files only for Serenity, but was using the Lagom build
version of the _HEADER, _IMPLEMENTATION, and _PREFIX variables. Thus if
pnp_ids.cmake was ever touched, the following error would be raised:
Userland/Libraries/LibEDID/EDID.cpp:18:18: fatal error:
LibEDID/PnpIDs.h: No such file or directory
18 | # include <LibEDID/LibEDID/PnpIDs.h>
Use the Serenity paths in pnp_ids.cmake and in the #include within
LibEDID itself.
This function will handle download failures. It doesn't support hashing
for integrity yet, but if the download times out or otherwise fails, the
build itself will fail. But default, file(DOWNLOAD) in CMake doesn't
fail the build; we must pass in and check a STATUS variable.
These tests are not meant as a replacement to test-js with the -b option
but are meant to test simple cases until that works.
Before this it was very easy to accidentally break bytecode since no
tests were run in bytecode mode. This hopefully makes it easier to spot
such regressions :^).
This just splits up the method to find the active DST rule for specified
time and time zone. This is to allow re-using the now split-off function
in upcoming commits.
For example, today, America/New_York has the format string "E%sT" and
uses US DST rules. Those rules indicate the %s should be replaced by a
"D" in daylight time and "S" in standard time.
Before this commit all consume_until overloads aside from the Predicate
one would consume (and ignore) the stop char/string, while the
Predicate overload would not, in order to keep behaviour consistent,
the other overloads no longer consume the stop char/string as well.
This commit adds support for building the SerenityOS userland with the
new [mold linker].
This is not enabled by default yet; to link using mold, run the
`Toolchain/BuildMold.sh` script to build the latest release of mold, and
set the `ENABLE_MOLD_LINKER` CMake variable to ON. This option relies on
toolchain support that has been added just recently, so you might need
to rebuild your toolchain for mold to work.
[mold linker]: https://github.com/rui314/mold
This downloads the UEFI's published PNP ID database and generates a
lookup table for use in LibEDID. The lookup table isn't optimized at
all, but this can be easily done at a later point if needed.
vdbgln() was responsible for ~10% of samples on pv's flamegraph for
RequestServer (under request_did_finish) when loading github.com in
Browser and recording a whole-system profile. This makes that almost
completely disappear.
This allows us to load modules from scripts.
This can be dangerous as it can load arbitrary files. Because of that it
fails and throws by default. Currently, only js and JavaScriptTestRunner
enable the default hook.
This also adds tests to test-js which test module code. Because we
form a spec perspective can't "enter" a module this is the easiest way
to run tests without having to modify test-js to have special cases for
modules.
To specify modules in test-js we use the extension '.mjs' this is to
ensure the files are not executed. We do still want to lint these files
so the prettier scripts have changed to look for '.mjs' files as well.
This also refactors interpreter creation to follow
InitializeHostDefinedRealm, but I couldn't fit it in the title :^)
This allows us to follow the spec much more closely rather than being
completely ad-hoc with just the parse node instead of having all the
surrounding data such as the realm of the parse node.
The interpreter creation refactor creates the global execution context
once and doesn't take it off the stack. This allows LibWeb to take the
global execution context and manually handle it, following the HTML
spec. The HTML spec calls this the "realm execution context" of the
environment settings object.
It also allows us to specify the globalThis type, as it can be
different from the global object type. For example, on the web, Window
global objects use a WindowProxy global this value to enforce the same
origin policy on operations like [[GetOwnProperty]].
Finally, it allows us to directly call Program::execute in perform_eval
and perform_shadow_realm_eval as this moves
global_declaration_instantiation into Interpreter::run
(ScriptEvaluation) as per the spec.
Note that this doesn't evalulate Source Text Modules yet or refactor
the bytecode interpreter, that's work for future us :^)
This patch was originally build by Luke for the environment settings
object change but was also needed for modules. So I (davidot) have
modified it with the new completion changes and setup for that.
Co-authored-by: davidot <davidot@serenityos.org>
Length and Percentage are different types, and sometimes only one or the
other is allowed in a given CSS property. This is a first step towards
separating them.
Each ZONE entry contains a RULES segment with one of the following:
* A DST rule name, which links the ZONE to a RULE entry holding the
DST rules to apply.
* A static offset to be applied to the STDOFF offset. This implicitly
means that the time zone is in DST during that time frame.
* A "-" string, meaning no offset is applied to the STDOFF offset, and
the time zone is in standard time during that time frame.
Previously all the added icons weren't available in the online version
of the man pages. This patch adds functionality to copy all the used
icons over when assembling the HTML version.
The way that lint-ports.py obtains the ports properties is unfortunately
very process intensive. You have to execute `./package.sh showproperty`
once for each property, for each port. Resulting in hundreds of
executions.
We were doing this work twice in both `check_package_files()` and in
`read_port_dirs()`. This resulted in a runtime of around ~10 seconds on
my machine. Removing the duplicate work and allowing the other code path
to utilize the to use the cached properties brought the runtime down to
~5 seconds on my machine.
Shellcheck barfs on many of the patterns we use in port scripts, the
check is already disabled when we run the script in CI, so we might as
well disable the check for pre-commit as well.
This adds a list of ports without descriptions to filter out the
existing ports with unexplained ports, this list should *not* be
appended to!
It also adds a (for now) disabled check that ensures all ports have
patches made with (or compatible with) git.
Since the build now happens in Build/$SERENITY_ARCH/ and not in Build/,
this updates check-symbols.sh to use the correct directory to check the
LibC symbols in. For some reason, the constant failures did not show
up as errors in CI.
This change unfortunately cannot be atomically made without a single
commit changing everything.
Most of the important changes are in LibIPC/Connection.cpp,
LibIPC/ServerConnection.cpp and LibCore/LocalServer.cpp.
The notable changes are:
- IPCCompiler now generates the decode and decode_message functions such
that they take a Core::Stream::LocalSocket instead of the socket fd.
- IPC::Decoder now uses the receive_fd method of LocalSocket instead of
doing system calls directly on the fd.
- IPC::ConnectionBase and related classes now use the Stream API
functions.
- IPC::ServerConnection no longer constructs the socket itself; instead,
a convenience macro, IPC_CLIENT_CONNECTION, is used in place of
C_OBJECT and will generate a static try_create factory function for
the ServerConnection subclass. The subclass is now responsible for
passing the socket constructed in this function to its
ServerConnection base; the socket is passed as the first argument to
the constructor (as a NonnullOwnPtr<Core::Stream::LocalServer>) before
any other arguments.
- The functionality regarding taking over sockets from SystemServer has
been moved to LibIPC/SystemServerTakeover.cpp. The Core::LocalSocket
implementation of this functionality hasn't been deleted due to my
intention of removing this class in the near future and to reduce
noise on this (already quite noisy) PR.
