This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Rename sql_statement to prepare_statement and statement_execute to
execute_statement. The former aligns more with other database libraries
(e.g. Java's JDBC prepareStatement). The latter reads less awkwardly.
This changes this:
```sh
profile -c "python3 -m test test_dict"
```
to this:
```sh
profile -- python3 -m test test_dict
```
This should be less confusing, hopefully!
This patch adds the "-n"/"--head-count" optional argument to specifiy
the maximum number of shuffled lines to output.
Idea from Andreas' FIXME roulette :^)
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.
Instead of assuming the virtual offset will be 8 hex digits (which is OK
for 32 bit values), just use the ":p" modifier to ensure it prints the
virtual offset as a pointer, so if the code is compiled for 64 bit CPUs,
it will use 16 hex digits accordingly.
Previously, hexdump used Core::File to read input into a fixed buffer.
This PR rewrites the file handling to use the more modern
Core::Stream::File, which reads data into spans. By using spans, we
can also simplify the rest of the code, which previously used memcpy
for array manipulation and relied on manual bookkeeping to keep track of
offsets.
Previously we labeled redirects as normal FrameLoader::Type::Navigation,
now we introduce a new FrameLoader::Type::Redirect and label redirects
with it. This will allow us to handle redirects in the browser
differently (such as for overwritting the latest history entry when a
redirect happens) :^)
The Core::System::create_jail function already provided the new jail
index as a result, so it was just a matter of using it when calling the
LibCore join_jail function to use the new jail.
And make it capable of printing to any Core::Stream.
This is useful on its own and can be used in a number of places, so move
it out and make it available as JS::print().
This implements the fastest seeking mode available for tracks with cues
using an array of cue points for each track. It approximates the index
based on the seeking timestamp and then finds the earliest cue point
before the timestamp. The approximation assumes that cues will be on
a regular interval, which I don't believe is always the case, but it
should at least be faster than iterating the whole set of cue points
each time.
Cues are stored per track, but most videos will only have cue points
for the video track(s) that are present. For now, this assumes that it
should only seek based on the cue points for the selected track. To
seek audio in a video file, we should copy the seeked iterator over to
the audio track's iterator after seeking is complete. The iterator will
then skip to the next audio block.
This adds two options:
- An option to print a specific track number only, and omit all others.
- An option to print each block for each track that is printed.
Tracks have a timestamp scale value that should be present which scales
each block's timestamp offset to allow video to be synced with audio.
They should also contain a CodecDelay element and may also contain a
TrackOffset that offsets the block timestamps.
The Demuxer class was changed to return errors for more functions so
that all of the underlying reading can be done lazily. Other than that,
the demuxer interface is unchanged, and only the underlying reader was
modified.
The MatroskaDocument class is no more, and MatroskaReader's getter
functions replace it. Every MatroskaReader getter beyond the Segment
element's position is parsed lazily from the file as needed. This means
that all getter functions can return DecoderErrors which must be
handled by callers.
Matroska::Reader functions now return DecoderErrorOr instead of values
being declared Optional. Useful errors can be handled by the users of
the parser, similarly to the VP9 decoder. A lot of the error checking
in the reader is a lot cleaner thanks to this change, since all reads
can be range checked in Streamer::read_octet() now.
Most functions for the Streamer class are now also out-of-line in
Reader.cpp now instead of residing in the header.
As new demuxers are added, this will get quite full of files, so it'll
be good to have a separate folder for these.
To avoid too many chained namespaces, the Containers subdirectory is
not also a namespace, but the Matroska folder is for the sake of
separating the multiple classes for parsed information entering the
Video namespace.
Previously, shuf exclusively read input from stdin. This PR adds an
option to read from a file using Core::Stream::File. Since a file might
contain arbitrary bytes, including null bytes, this PR represents lines
as Spans of Bytes instead of Strings.
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.
Currently, all handling of pending dialogs occurs in PageHost. In order
to re-use this functionality to run WebDriver in a headless move, move
it to Page.
