Let's do one of those checklist things

• [x] decent (:tm:) parser
• [x] decent (:tm:) AST for the parser
• [x] Some way to express $(foo | bar)
• [x] highlighting the AST
• [x] would you like some completely event-based shells in your OS?
  • [x] I totally would!
• [x] evaluating the AST
  • [x] evaluating commands until getting an argv and a list of redirections
  • [x] get/set variables
  • [x] actually running commands
  • [x] redirections
  • [x] in-shell persistent redirections with empty commands
    • [x] giving some means to clean that mess up (fd>&-?)
  • [x] pipes
  • [x] comprehensive test of all the weird stuff/features
• [x] completions
• [x] builtin_alias because you people can't decide whether cat should be a fun cat or an officer cat.
• [x] ...also ~/shell-init.sh
• [x] ...and also a few setopt things (completely unrelated to sh's setopt)

This is still work in progress:

• [x] Add SpinLock class
• [x] Serialize debug output with new SpinLock class
• [x] Add Processor structure and assign it to each CPU using the fs segment register
• [x] Get Scheduler to work on the BSP using software context switching
• [x] Add some locks to MM, Process, and other places
• [x] Boot each AP all the way into the Scheduler::idle_loop
• [x] Expose all processors in /proc/cpuinfo
• [x] Add CPU graphs and current processor information to SystemMonitor

These are pretty common on older LGA1366 & LGA1150 motherboards. I havent had the chance to test the driver with the real NIC, waiting for the PSU for this motherboard to arrive in the mail :) If anyone has a motherboard with a RTL8168/RTL8111 variant and wants to test it while im waiting, it would be greatly appreciated!

@bugaevc

This adds an incomplete implementation of the test util, missing some user/group checks, and -l STRING. created because me want shell tests, and we had no way to compare things.

"minor" issue, if I name it "test", cmake complains that there's already a test target. if I try to manually rename the target (I tried set_target_properties(Test PROPERTIES RUNTIME_OUTPUT_NAME test)), ninja complains that there are multiple rules that generate Userland/test, which I assume is the test target binary. not sure how to fix that.

This is a follow-up to https://github.com/SerenityOS/serenity/pull/8455

• Fix a few things
• Let's try not setting owner for non-recursive mutexes, perhaps it's faster. (Although gettid() should be fast anyway.)
• Port LWSP semaphore tests

Now, about those tests. LWSP uses 100 threads (NPTL is very scalable — 100 threads is nothing). I turned that down to 10 threads for us (dunno how scalable our threading is, but 10 sounds reasonable); the downside is there's obviously less contention, so less chances to reproduce the potentially problematic patterns.

But even with that, the test sometimes passes, and sometimes hangs (on test_semaphore_as_lock(), even). Which is, uh, unexpected, but also good, it means we caught a bug that we can fix and make things better. That being said, I don't know where the bug is; given that LWSP test works on Linux each time, could this bug a race in Kernel-side futex implementation?

Fix #743 .

This is currently incomplete. It does not support CFF fonts (that's probably best added in a later PR), and also does not support composite TTF outlines (will be adding that soon).

I posted a screenshot on the linked issue of the demo application and TrueType Label widget I added, but I haven't included them here yet, since they require a TTF font to be present on the system. Repeating my question from the issue - would there be any licensing issues with including a font file within the project?

Note to reviewers: I don't know if my use of ByteBuffer and different smart pointers (RefPtr, OwnPtr) is correct and/or idiomatic, so it'd be great if you could comment on that.

Notes on the implementation I've tried to make this nearly zero-allocation and zero-copy beyond the buffer created to read the file, and the buffer allocated by Rasterizer. Structures from the font file aren't parsed on load. The Font object stores slices of the underlying buffer that correspond to the tables we are interested in. This means that startup should be fast, but rastering glyphs to bitmaps would be slightly slower. Which should be okay, since glyph bitmaps should be cached anyway.

A Font cannot be used directly, it must be scaled to get a ScaledFont wrapper. The API requires users to first get a glyph_id for a codepoint, and then get a bitmap for the glyph_id. This is one step more than the current Font API, but I designed this keeping in mind a future HarfBuzz-like shaper, which returns a sequence of glyph IDs after shaping a run of text.

This PR will allow us to use the newly implemented features in TTY to communicate with serial devices (like proper newline handling, control sequences, etc.).

Currently, a very rudimentary IRQ handler is used for handling incoming data, and that should definitely be changed.

Paging the hardware experts @IdanHo @supercomputer7

Known problems: input is not available from non-emulated PCI serial devices, as we do not get interrupts from them.

Since RefPtr decrements the ref counter to 0 and after that starts destructing the object, there is a window where the ref count is 0 and the weak references have not been revoked.

Also change WeakLink to be able to obtain a strong reference concurrently and block revoking instead, which should happen a lot less often.

Fixes #4621

@bcoles Does this solve this issue for you? I haven't tested it a whole lot, but I also haven't run into the crash you're seeing. @bugaevc Memory order review, please? ;-)

This is my work on converting Serenity to be built with CMake, loosely based on @awesomekling's prior work.

This is somewhat WIP, as I've broken some things that work with the old buildsystem.

Everybody, please try to fix building on systems you're interested in :smile: (tagging a few people: @jarhill0 @Pagghiu @jcs @brynet @zaklaus @BobbyRaduloff)

Oh, and the ports are most likely broken too. We're going to want to figure out how we would want them to work in the brave new out-of-tree builds world.

It is time. We must march forward towards TLS 1.2

Differentiate terminal and GUI applications with icons next to the name of the application within the man pages of the Help application. I removed the short descriptions after the name of the application as they all seemed to be contained within the description and I feel it helps differentiate them better.

As suggested when @jntrnr revisited Serenity: https://youtu.be/_QAsHkEKvN0?t=480

Example of a GUI application:

Verses a terminal application:

This patch enables the user to click anywhere on the slide. A pop-up will ask for some text and that text will be inserted, where the user clicked. It also adds the ability for the presentation to be serialized to JSON, allowing saving of files. It always adds text in font size 16 and in Liberation Serif. The next step would probably be to add a tool system similar to PixelPaint.

These are things that tripped me up more times than I can to admit while working on #16637 and #16770, but I didn't want to change behavior too much in those PRs beyond the fallible changes.

My attempt to port (the SDL2 version of) this little cute game to SerenityOS. :^)

Depends on #16815.
