29863d3815 LibC: unsetenv() should take a const char*, not a char*. 2019-05-19 15:19:48 +02:00

5f597d0cb2 WindowServer: Improve client write handling a little 
* EPIPE now correctly deletes the client connection
* EAGAIN (which is now returned by the kernel if the write buffer fills)
  terminates the connection also

d8b74c8c86 Kernel: Check can_write for blocking write 
This way the socket write buffer sizes are respected, and things that
exceed them get sent EAGAIN.

635eb20289 Kernel: Add the ability to debug poll/select independently of read/write 2019-05-19 14:13:49 +02:00

c7d8aa6969 IDEDiskDevice: Support reading multiple sectors at a time with DMA. 
This is another sizable improvement to GCC compile times.

ed79116e94 IDEDiskDevice: Use wait_for_irq() when waiting for DMA transfers. 
Also make sure we return any device errors to caller.

c818773983 IDEDiskDevice: Add support for DMA reads. 
I've only tested this with the PIIX3 chipset QEMU emulates, but it works
pretty well here. GCC compile times are cut roughly in half :^)

6e305bf838 AK: Simplify quick_sort() and improve Vector iterators a bit. 2019-05-19 01:53:51 +02:00

853597200e Kernel: Remove relocation-related code since it's not used by the kernel. 
If/when we need this in the future, we can bring it back. Right now it's
just sitting there making the ELF code look huge when it's not.

75866438b5 Kernel: Don't page in entire file immediately on mmap(). 
If we just don't do anything, the page fault handler will load the file
incrementally as-needed instead. :^)

7900da9667 Kernel: Make sure we never put the colonel thread in the runnable list. 
This would cause it to get scheduled unnecessarily.

64a4f3df69 Kernel: Add a Thread::set_thread_list() helper to keep logic in one place. 2019-05-18 20:28:04 +02:00
Andreas Kling
8c7d5abdc4 Kernel: Refactor thread scheduling a bit, breaking it into multiple lists. 
There are now two thread lists, one for runnable threads and one for non-
runnable threads. Thread::set_state() is responsible for moving threads
between the lists.

Each thread also has a back-pointer to the list it's currently in.

99dd60611f Kernel: Fix select with a 0 timeout 
select essentially has 3 modes (which is presumably why we're finding it
so hard to get this right in a reliable way :)).

1. NULL timeout -- no timeout on blocking
2. non-NULL timeout that is not zero'd -- timeout on blocking
3. non-NULL but zero timeout -- no blocking at all (immediate poll)

For cases 1 and 2, we want to block the thread. We have a timeout set
only for case 2, though.

Case 3 should not block the thread, and does not have a timeout set.

d2c3749cf3 Kernel: Don't allow dump_backtrace() to call dump_backtrace(). 
That was not a very graceful looking loop to be stuck in.

cdaf8cd656 Kernel: select() was transferring the readfds into the exceptfds vector. 
Just a mistake I spotted while reading the code. We don't actually detect
exceptional descriptor events yet.

ba92c07a75 Kernel: Make sure to clear FD sets when preparing for a select 
NULL sets can happen, and we don't want to incorrectly return FDs which
aren't in the set too.

df74a9222f Kernel: Fix timeout support in select 
The scheduler expects m_select_timeout to act as a deadline. That is, it
should contain the time that a task should wake at -- but we were
directly copying the time from userspace, which meant that it always
returned virtually immediately.

At the same time, fix CEventLoop to not rely on the broken select behavior
by subtracting the current time from the time of the nearest timer.

33d0916d29 WindowServer: Add support for fullscreen windows. 
Fullscreen windows are rendered alone and above everything else when they
are active, and as part of the regular window stack order when something
else is active.

Currently windows cannot be made fullscreen after-the-fact, but must have
the fullscreen flag included in their CreateWindow message.

It should not possible to interact with the menu, taskbar or window frame
while the active window is fullscreened. :^)

5babcac289 Build: Install most headers to Root (and libcore.a/libgui.a) 
This makes out-of-tree linking possible. And at the same time, add a
CMakeToolchain.txt file that can be used to build arbitrary cmake-using
applications on Serenity by pointing to the CMAKE_TOOLCHAIN_FILE when
running cmake:

    -DCMAKE_TOOLCHAIN_FILE=~/code/serenity/Toolchain/CMakeToolchain.txt

2d98f4e28f Kernel: Make the times() syscall return something other than 0. 
Based on the description I read, this syscall doesn't seem completely
reasonable, but let's at least return a number that is likely to change
between invocations in case somebody depends on that happening.

a182ea8c60 Kernel: After creating our GDT, make sure CS refers to the right descriptor. 
This will allow us to boot from e.g GRUB which will have a different looking
GDT in effect before we start moving things around.

e8ae2c952e Kernel: Put GDT and IDT in BSS rather than runtime-allocating them. 2019-05-17 18:25:50 +02:00
Andreas Kling
e0ff07bb57 Kernel: Make sure we load DS/ES/FS/GS/SS immediately after making the GDT. 2019-05-17 18:23:08 +02:00
Andreas Kling
a15857ea28 Kernel: Clear the X86 direction flag (DF) in the boot loader. 
I'm not sure who is responsible for clearing this, but IIUC the C++ ABI
expects it to be clear on function entry, so just to be on the safe side..

20e55c0120 GInputBox: Use whichever is greater: the approximate size of the title, or the label's text 
Might be an idea to add a minimum size constrain in window server
instead, since it knows the exact dimensions? But this is a simple fix
that seems to do the job.

77dfd419e9 LibCore: Move AK/ArgsParser to LibCore/CArgsParser 
Also rename the classes to match LibCore naming style.
This means that it's no longer incorrectly linked into LibC and Kernel.
