2023-02-25AK: Add operator""_{short_,}string to create a String from a literalLinus Groh
We briefly discussed this when adding the new String type but couldn't settle on a name. However, having to use String::from_utf8() on every literal string is a bit unwieldy, so let's have these options available! Naming-wise '_string' is not as short as 'sv' but should be relatively clear; it also matches '_bigint' and '_ubigint' in length. '_short_string' may be longer than the actual string itself, but it's still an improvement over the static function :^) Since our C++ source files are UTF-8 encoded anyway, it should be impossible to create a string literal with invalid UTF-8, so including that in the name is not as important as in the function that can receive arbitrary data.

2023-02-25Meta: Allow disabling LibWeb fuzzerskleines Filmröllchen
The LibWeb fuzzer build is really slow, so for local builds it is useful to disable it when you're not interested in running that fuzzer. Co-authored-by: Andrew Kaster <akaster@serenityos.org>
2023-02-25LibGfx: Parse WebP VP8L chunk headerNico Weber
For now, just dbgln_if() all data. Eventually we'll want to use at least width and height.

2023-02-25LibGfx: Add link to webp overviewNico Weber
2023-02-25LibGfx: Parse some of WebP 'VP8 ' chunkNico Weber
This is for lossy compression, in which case a WebP file is a single VP8 key frame. This only parses the 10-byte frame header, which contains image dimensions (and some other things). For now, just dbgln_if() all data. Eventually we'll want to use at least width and height.

2023-02-25LibGfx: Add a FIXME to WebPImageDecoderPlugin::icc_data()Nico Weber
2023-02-25LibGfx: Add a WebPLoadingContext::error() helperNico Weber
No behavior change. (Well, technically, this now correctly sets the state to Error if the first chunk is neither of 'VP8 ', 'VP8L', 'VP8X'. But no *interesting* behavior change.)
2023-02-25LibDSP: Get rid of DeprecatedStringkleines Filmröllchen
This was a rather easy change, since only parameter names make use of strings in the first place. This also improves OOM resistance: If we can't create a parameter name, we will just set it to the empty string.
2023-02-25Kernel: Mark sys$prctl() as not needing the big lockLiav A
This syscall has sufficient locking and therefore it doesn't need the big lock being taken.

2023-02-25Lagom: Build LibELF on arm64Nico Weber
This seems to build fine now on Arm Macs.
2023-02-24LibDeviceTree: Use unchecked_append() in path parsingMacDue
try_append() checks if the vector should increase capacity and if so grows the vector. unchecked_append() verifies the vector already has enough capacity, and will never grow the vector.
2023-02-24Revert "LibDeviceTree: Propagate try_append() errors while parsing paths"Linus Groh
This reverts commit f064f5f36e6c4ec9d96122815ed359d6290f8de2. As Andrew points out, this append is not actually fallible in practice, since the loop is terminated once the vector size reaches its inline capacity. https://github.com/SerenityOS/serenity/pull/17606#discussion_r1117662246
2023-02-24Kernel+Userland: Refine preventing syscall annotations of Regions optionLiav A
Instead of using a special case of the annotate_mapping syscall, let's introduce a new prctl option to disallow further annotations of Regions as new syscall Region(s).

2023-02-24Kernel/FileSystem: Simplify the ProcFS significantlyLiav A
Since the ProcFS doesn't hold many global objects within it, the need for a fully-structured design of backing components and a registry like with the SysFS is no longer true. To acommodate this, let's remove all backing store and components of the ProcFS, so now it resembles what we had in the early days of ProcFS in the project - a mostly-static filesystem, with very small amount of kmalloc allocations needed. We still use the inode index mechanism to understand the role of each inode, but this is done in a much "static"ier way than before.
2023-02-24Kernel: Fix typo proccess => process in a name of Process methodLiav A
2023-02-24AK+Kernel: Add includes before removing Kernel/ProcessExposed.hLiav A
Apparently without this file, we won't be able to compile due to missing includes to TimeManagement and KBufferBuilder.
2023-02-24Browser+LibWeb+WebContent: Store cookie expiry times in UTCTimothy Flynn
We are currently converting parsed expiry times to local time, whereas the RFC dictates we parse them as UTC. When expiring cookies, we must also use the current UTC time to compare against the cookies' expiry times.

2023-02-24LibWeb: Stop overflow clip box aggregation on reached stacking contextAliaksandr Kalenik
2023-02-24Revert "LibWeb: Fix clip of hidden overflow..."Aliaksandr Kalenik
This reverts commit eb1ef59603c13c43b87c099c43c4d118dc8441f6. The idea of saving clip box to apply it to handle `overflow: hidden` turned out to break painting if box is painted before it's containing block (it is possible if box has negative z-index).

2023-02-24PixelPaint: Make "Add Mask" action undoableTim Ledbetter
2023-02-24PixelPaint: Save layer mask when adding to the UndoStackTim Ledbetter
This makes undoing actions performed on layer masks work as expected. did_modify_bitmap() is now also called on redo, to ensure the layer mask is displayed correctly.
2023-02-24LibGfx: Remove single-code point Font::glyph_or_emoji_width APITimothy Flynn
All callers are now aware of multi-code point emoji (and must remain so going forward).

2023-02-24LibPDF: Refactor *Font classesRodrigo Tobar
The PDFFont class hierarchy was very simple (a top-level PDFFont class, followed by all the children classes that derived directly from it). While this design was good enough for some things, it didn't correctly model the actual organization of font types: * PDF fonts are first divided between "simple" and "composite" fonts. The latter is the Type0 font, while the rest are all simple. * PDF fonts yield a glyph per "character code". Simple fonts char codes are always 1 byte long, while Type0 char codes are of variable size. To this effect, this commit changes the hierarchy of Font classes, introducing a new SimpleFont class, deriving from PDFFont, and acting as the parent of Type1Font and TrueTypeFont, while Type0 still derives from PDFFont directly. This distinction allows us now to: * Model string rendering differently from simple and composite fonts: PDFFont now offers a generic draw_string method that takes a whole string to be rendered instead of a single char code. SimpleFont implements this as a loop over individual bytes of the string, with T1 and TT implementing draw_glyph for drawing a single char code. * Some common fields between T1 and TT fonts now live under SimpleFont instead of under PDFfont, where they previously resided. * Some other interfaces specific to SimpleFont have been cleaned up, with u16/u32 not appearing on these classes (or in PDFFont) anymore. * Type0Font's rendering still remains unimplemented. As part of this exercise I also took the chance to perform the following cleanups and restructurings: * Refactored the creation and initialisation of fonts. They are all centrally created at PDFFont::create, with a virtual "initialize" method that allows them to initialise their inner members in the correct order (parent first, child later) after creation. * Removed duplicated code. * Cleaned up some public interfaces: receive const refs, removed unnecessary ctro/dtors, etc. * Slightly changed how Type1 and TrueType fonts are implemented: if there's an embedded font that takes priority, otherwise we always look for a replacement. * This means we don't do anything special for the standard fonts. The only behavior previously associated to standard fonts was choosing an encoding, and even that was under questioning.
2023-02-24LibPDF: Add new error construction functionsRodrigo Tobar
These should make it easier to create specific errors, specially when wanting to create a formatted message.
2023-02-24LibPDF: Allow show_text to return errorsRodrigo Tobar
Errors can (and do) occur when trying to render text, and so far we've silently ignored them, making us think that all is well when it isn't. Letting show_text return errors will allow us to inform the user about these errors instead of having to hiding them.
2023-02-24LibGfx+Tests: Add test for webp ICC loading and fix bugNico Weber
I drew the two webp files in Photoshop and saved them using the "Save a Copy..." dialog, with ICC profile and all other boxes checked. (I also tried saving with all the boxes unchecked, but it still wrote an extended webp instead of a basic file.) The lossless file exposed a bug: I didn't handle chunk padding correctly before this patch.

2023-02-24LibGfx: Use LibUnicode to filter code points that cannot start an emojiTimothy Flynn
2023-02-24LibGfx: Use the paths to emoji images generated alongside emoji dataTimothy Flynn
Rather than formatting the paths at runtime, as vformat is quite heavy in a profile.
2023-02-24LibUnicode: Add a method to check if a code point could start an emojiTimothy Flynn
2023-02-24LibUnicode: Generate the path to emoji images alongside emoji dataTimothy Flynn
This will provide for quicker emoji lookups, rather than having to discover and allocate these paths at runtime before we find out if they even exist.
2023-02-24Base: Add a trailing newline to emoji-serenity.txtTimothy Flynn
We currently aren't parsing the last line of emoji-serenity.txt because Core::Stream does not think the last line is readable. We should, of course, fix Core::Stream. But keeping a trailing newline here is nice anyways.
