Previously, `AnonymousBuffer::create_with_size(0)` returned an error
because POSIX `mmap` rejects a zero length with `EINVAL`, and Windows
`CreateFileMapping` rejects a zero maximum size for an anonymous
mapping. This caused a crash when using `--headless=text` with zero
size pages like `about:blank`.
If an error occurred during a previous test run, the file might be
lying around still. This should clear up CI failures happening on macOS
at the moment.
ENABLE_WINDOWS_CI and the *_CI presets were initially added back when
the AK library and all the AK Test* executables were the only targets
that supported building and running in CI. Since then, almost all the
targets in the codebase are built on Windows besides the following:
- LibLine
- test-262-runner
Since these targets above are not required to actually run or test the
browser on Windows in its current experimental state, fully disabling
them should be fine for now.
ENABLE_WINDOWS_CI was also used to exclude test-web from ctest. This
can be fully disabled on Windows for now until proper runtime support
is added.
The remaining locations were all using ENABLE_WINDOWS_CI as a proxy for
ENABLE_ADDRESS_SANITIZER, so we can just be explicit instead.
The new presets map much more directly to the unix Release, Debug, and
Sanitizer presets which should make setting up ladybird on Windows less
confusing.
We also make the new Windows_Experimental_Release preset the default in
ladybird.py to match Unix.
SocketAddressWindows.h contains a bunch of copy-pasted Windows
definitions. This started causing ad-nauseam redefinition errors when
implementing the HTTP disk cache for Windows.
Instead, let's forward-declare the types we can in SocketAddress.h and
only define the couple of constants that we need. We can then assert at
compile-time that we defined them correctly.
These tests previously only ran on SerenityOS. They needed test input
location changes. The Stream tests also needed to explicitly set
SO_REUSEADDR for the tcp servers.
Increase the step timeouts on Linux from 50 to 75 milliseconds, since
we're seeing the occasional timeout on CI. For macOS, we should probably
be able to execute the tests a bit quicker than 500ms per step.
This test could fail when `/tmp/testfile` already exists.
There also shouldn't be a need to wait so long for this test,
except for on MacOS, where the `FileWatcher` implementation is
apparently less reliable.
It's expensive to determine the system time zone from disk each time it
is requested. This makes LibUnicode cache the result, and provides an
API to clear that cache. This will let us set up a monitor to watch for
system time zone changes in platform-dependent ways.
When asked to monitor a file (not a directory), we often need to instead
monitor the parent directory to receive FS events. For example, when a
symbolic link is deleted/created, we don't receive any events unless we
are watching the parent.
The changes to tests are due to LibTimeZone incorrectly interpreting
time stamps in the TZDB. The TZDB will list zone transitions in either
UTC or the zone's local time (which is then subject to DST offsets).
LibTimeZone did not handle the latter at all.
For example:
The following rule is in effect until November 18, 6PM UTC.
America/Chicago -5:50:36 - LMT 1883 Nov 18 18:00u
The following rule is in effect until March 1, 2AM in Chicago time. But
at that time, a DST transition occurs, so the local time is actually
3AM.
America/Chicago -6:00 Chicago C%sT 1936 Mar 1 2:00
On argument swapping to put positional ones toward the end,
m_arg_index was pointing at "last arg index" + "skipped args" +
"consumed args" and thus was pointing ahead of the skipped ones.
m_arg_index now points after the current parsed option arguments.
This method (unlike can_read_line) ensures that the delimiter is present
in the buffer, and doesn't return true after eof when the delimiter is
absent.
This overload is currently unused. When used, it doesn't compile due to
mismatched return types in the handler provided to the function and the
type of `on_resolution`.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
Let's replace this bool with an `enum class` in order to enhance
readability. This is done by repurposing `MappedFile`'s `OpenMode` into
a shared `enum` simply called `Mode`.
For example, LibJS will need to parse date strings of the form:
Wed Dec 31 1969 19:00:00 GMT-0500 (Eastern Standard Time)
This string contains both the time zone offset (-05:00) and a display
name for the time zone (Eastern Standard Time). Because we will already
handle time zone adjustments when we handle the offsets, we will want to
just skip the time zone name. This patch will let us use a format string
of the form "GMT%z (%+)" to do so.
LibCore currently cannot depend on LibTimeZone directly. All build-time
code generators depend on LibCore, so there'd be a circular dependency:
LibCore -> LibTimeZone -> GenerateTZData -> LibCore.
So to support parsing time zone names and applying their offsets, add a
couple of weakly-defined helper functions. These work similar to the way
AK::String declares some methods that LibUnicode defines. Any user who
wants to parse time zone names (from outside of LibCore itself) can link
against LibTimeZone to receive full support.
The internal reuse of FixedMemoryStream makes this straightforward.
There alread is one user of the new API, demonstrating the need for this
change beyond what I said out to use it for :^)
Just like with input buffered streams, we don't currently have a use
case for output buffered streams which aren't seekable, since the main
application are files.
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.
Returning a reference resulted in Mail's use of Promise causing a crash.
Also, awaiting an already-awaited promise is an odd thing to do anyway,
so let's just make it release the resolved/rejected value instead of
returning a reference to it.

The previous iteration of this API was somewhat odd and rough in random
places, which degraded usability and made less than perfect sense.
This commit reworks the API to be a little closer to more
conventional promise APIs (a la javascript promises).
Also adds a test to ensure the class even works.
