cc5ee3bff4 Vector: Add insert() overload that takes a const T&. 2019-05-17 04:59:56 +02:00
Andreas Kling
cde47089d2 Kernel: Remove some unnecessary massaging of region base/size pairs. 
These will be appropriately rounded by the allocate_range(), so call sites
can stop worrying about it.

6957825444 Kernel: Factor out range allocation from Process::allocate_region*(). 
These functions were doing exactly the same thing for range allocation, so
share that code in an allocate_range() helper.

Region allocation will now also fail if range allocation fails, which means
that mmap() can actually fail without falling apart. Exciting times!

87b54a82c7 Kernel: Let Region keep a Range internally. 2019-05-17 04:32:08 +02:00

4a6fcfbacf Kernel: Use a RangeAllocator for kernel-only virtual space allocation too. 2019-05-17 04:02:29 +02:00

b1bb737704 Kernel: Remove Process::m_next_address. 
This isn't needed now that we have RangeAllocator. :^)

45ff3a7e6a Kernel: Make Thread::kernel_stack_base() work for kernel processes. 2019-05-17 03:43:51 +02:00
Andreas Kling
c414e65498 Kernel: Implement a simple virtual address range allocator. 
This replaces the previous virtual address allocator which was basically
just "m_next_address += size;"

With this in place, virtual addresses can get reused, which cuts down on
the number of page tables created. When we implement ASLR some day, we'll
probably have to do page table deallocation, but for now page tables are
only deallocated once the process dies.

c56e3ebee1 Always dump QEMU CPU state on CPU reset. 2019-05-17 00:06:23 +02:00

bcb7893156 WindowServer: Don't treat bottom titlebar edge as part of the border. 
We were allowing initiation of resize from the bottom titlebar edge
since everything inside the window frame that's not either inside the
title bar, or inside the window content, is considered the border.

f196e2fcda Terminal: Set original window title to "Terminal" 
Don't rely on the shell setting the window title using escape sequences.

4e7e2950bc WindowServer: Fill unbacked windows with their background color. 
This avoids flashing a content-less window frame during client startup.

0ba4ceb2cd Added CProcessStatisticsReader to avoid having to parse /proc/all (#35) 
* Added CProcessStatisticsReader to avoid having to parse /proc/all

* Took @awesomekling's feedbacks into account

* Fixed indentation and replaced tabs by spaces

174639b7f0 Kernel: Symbolicate userspace backtraces using ELFLoader. 
Stash away the ELFLoader used to load an executable in Process so we can use
it for symbolicating userspace addresses later on. This will make debugging
userspace programs a lot nicer. :^)

e20aecefba LibC: Don't clobber errno in dbgprintf(). 2019-05-16 16:24:22 +02:00

f1f3cd58b0 FileSystem: fix errno on lseek() beyond the bounds of a file 
These are all EINVAL. Also remove bogus assert on metadata.size.

abb7455163 LibC/Shell: Add unsetenv(), and unset builtin calling it in Shell. 2019-05-16 14:32:09 +02:00
Robin Burchell
b2dd12daac LibC: Change putenv (and getenv) to not copy, but directly return the environ values. 
This is in keeping with how putenv should function. It does mean that
the shell's export command now leaks, but that's not a difficult fix.

Contributes to #29.

4dad585609 LibC: Allow {AF,PF}_UNIX as well as {AF,PF}_LOCAL 
Seems that these are equivilent. POSIX specifies _LOCAL, but a lot of
software uses _UNIX.

619489da62 LibC: Define a SOMAXCONN value in socket.h 
No idea if this is sensible; but some software will look for it.

2f4e7edee5 Kernel: Simplify dump_backtrace() API for clients. 
It makes no sense that clients had to worry about whether or not KSyms
were loaded.

c4610b825d WSWindowManager: Fix a small whoopsie with double click delivery 
We must reset the click clock to invalid after delivering the double
click event. Otherwise, a subsequent click will make us (incorrectly)
deliver another double click.

f55965b5e8 WindowServer/GMenu: Adjust the popup position to fit the window inside the screen

3cba2a8a78 Kernel: Add a beep() syscall that beeps the PC speaker. 
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.

ac2a3b65bb makeall: Use set -e to exit on failure 
And pretty the building/installing up a little, rather than a huge chain of &&

219f2f988e BuildIt: use set -e to fail immediately on error
