Jonas 'Sortie' Termansen
2a4a51fafc Added getline(3), getdelim(3), sortix_gets(3) and gets(3). 
gets(3) exists and is an alias for sortix_gets(3) if _SORTIX_SOURCE.

sortix_gets(3) returns a pointer to a safe newly read and allocated line.

4804e60a8b Fixed race condition when building libmaxsi with -j.

 2012-02-12 13:54:07 +01:00
Jonas 'Sortie' Termansen
c8dfe630af Removed annoying warnings when declaring x64 systemcalls. 
Actually, the warnings are true, but that's a task for later.

Jonas 'Sortie' Termansen
fec176fa15 Refactored the libmaxsi/ directory. 
C and C++ files are now kept together and so are the mxmpp declarations.

Header files are now stored in include/ and mxmpp'd into preproc/.

All other code now -I ../libmaxsi/preproc.

And other stuff to make this happen, including refactoring Makefile.
 2012-02-12 13:20:53 +01:00

b4131def9f The offsetof macro now expands to __builtin_offsetof.

Accidentally commited them. Oops.
 2012-02-11 19:03:17 +01:00
Jonas 'Sortie' Termansen
ed68db03fb Replaced SORTIX_EXTENSIONS macro with _SORTIX_SOURCE macro. 
<features.h> declares _SORTIX_SOURCE if no conflicting macros are
declared, such as _GNU_SOURCE.

Fixed g++ automatically declaring _GNU_SOURCE, but Sortix isn't GNU.

Replaced SORTIX_UNIMPLEMENTED macro with __SORTIX_SHOW_UNIMPLEMENTED.
 2012-02-11 18:51:55 +01:00

Jonas 'Sortie' Termansen
028867ab9d Removed the unused and deprecated old <libmaxsi/sortix-keyboard.h> API. 
This has been entirely replaced by stdin and <sys/termmode.h>.
 2012-02-10 13:46:26 +01:00
Jonas 'Sortie' Termansen
5fde8e13ed Blocking systemcalls now return EBLOCKING instead of EWOULDBLOCK. 
EWOULDBLOCK is now used when it wanted to block, but didn't.

ecc3114f2a Refactored the system to use the new Terminal interface. 
This will allow development of a better terminal providing stdin.

Added new system calls settermmode(2) and gettermmode(2) declared in
<sys/termmode.h>. They allow querying and changing the current mode of
terminals (enabling raw keyboard data, signal handling, line buffering,
UTF-8 encoding stdin, and more). However, all that is unsupported by the
current terminal device driver.

Added KBKEY_ENCODE and KBKEY_DECODE macros to <sys/keycodes.h> which allows
encoding the kbkey format in UTF-32 characters.

ead0e1523f Refactored the kernel keyboard API, but kept system calls compatible. 
Caps lock now works as caps lock, not as shift lock.

This new design will allow implementing a working tty, such that stdin is
the only way to access the keyboard, instead of the current hacky way of
using a special system call to read from the keyboard.

Added a new system header file <sys/keycodes.h> defining the constants for
every key on the keyboard. This will be used in future APIs.

The main change is to split the keyboard driver into a class that reads
from the keyboard, while another class handles the translation into
printable characters (if possible). This allows a terminal driver based
on logical key presses and printable characters, instead of a terminal
driver based only on unicode-ish codes.

f29f6dd053 ValidateHeap is now only called when PARANOIA is at least 2.

46e717e30f Revert ".so's are no longer installed into sysroot as there are no kernel support." 
This reverts commit e6db1874e7ed16a6987d5a86d7f6c10cd8b0ffff.

These dummy .so's are actually OK.

ad200ffa91 Added getpagesize(2) with the new return type size_t. 
This function is non-standard  and size_t is better than int here.

8eebe18922 Added an implementation of puts(3) because gcc needs it. 
I still didn't add it to stdio.h since it's still stupid.
 2012-01-08 14:30:50 +01:00
Jonas 'Sortie' Termansen
25d8551b26 Moved _start into crtbegin.o as that's where the cross compiler wants it. 2012-01-08 14:30:50 +01:00

Jonas 'Sortie' Termansen
fdbd4ca90d Implemented large parts of the stdio(3), including fprintf. 
Made FILE an interface to various backends. This allows application writers
to override the standard FILE API functions with their own backends. This
is highly unportable - it'd be nice if a real standard existed for this.
glibc already does something like this internally, but AFAIK you can't hook
into it.

Added fdopen(3), fopen(3), fregister(3), funregister(3), fread(3),
fwrite(3), fseek(3), clearerr(3), ferror(3), feof(3), rewind(3), ftell(3),
fflush(3), fclose(3), fileno(3), fnewline(3), fcloseall(3), memset(3),
stdio(3), vfprintf(3), fprintf(3), and vprintf(3).

Added a file-descriptor backend to the FILE API.

fd's {0, 1, 2} are now initialized as stdin, stdout, and stderr when the
standard library initializes.

fcloseall(3) is now called on exit(3).

decl/intn_t_.h now @include(size_t.h) instead of declaring it itself.

Added <stdint.h>.

The following programs now flush stdout: cat(1), clear(1), editor(1),
init(1), mxsh(1).

printf(3) is now hooked up against vprintf(3), while Maxsi::PrintF
remains using the system call, for now.

Jonas 'Sortie' Termansen
4841d83ff8 Added calloc(3). 2011-12-24 04:05:38 +01:00
Jonas 'Sortie' Termansen
0515111314 The initial ramdisk is now mapped onto a special location. 
This fixes issues where it did not fit into the first few MiB,
or that GRUB loaded it someplace weird.

The kernel heap is now also protected against growing into the
ramdisk and the kernel stack.

c0c20860ed Lots of improvements to 64-bit Sortix. 
Fixed 64-bit-ness bug in BSR() and BSF().
Added 64-bit system call stubs in libmaxsi.
Added a Elf64 program loader.
Fixed uninitialized memory bug in the scheduler.
x64/boot.s now takes care of user-space memory permissions.
Fixed bug in x64/syscall.s

That's right. The system now boots in 64-bit mode.

It is horribly unstable, though.

0b1c2a77c9 x64 now compiles again and runs on real hardware.

2afe9d1fd6 Implemented the fork() system call and what it needed to work properly. 
This commit got completely out of control.

Added the fork(), getpid(), getppid(), sleep(), usleep() system calls, and
aliases in the Maxsi:: namespace.

Fixed a bug where zero-byte allocation would fail.

Worked on the DescriptorTable class which now works and can fork.

Got rid of some massive print-registers statements and replaced them with
the portable InterruptRegisters::LogRegisters() function.

Removed the SysExecuteOld function and replaced it with Process::Execute().

Rewrote the boot sequence in kernel.cpp such that it now loads the system
idle process 'idle' as PID 0, and the initization process 'init' as PID 1.

Rewrote the SIGINT hack.

Processes now maintain a family-tree structure and keep track of their
threads. PIDs are now allocated using a simple hack. Virtual memory
per-process can now be allocated using a simple hack. Processes can now be
forked. Fixed the Process::Execute function such that it now resets the
stack pointer to where the stack actually is - not just a magic value.
Removed the old and ugly Process::_endcodesection hack.

Rewrote the scheduler into a much cleaner and faster version. Debug code is
now moved to designated functions. The noop kernel-thread has been replaced
by a simple user-space infinite-loop program 'idle'.

The Thread class has been seperated from the Scheduler except in Scheduler-
related code. Thread::{Save,Load}Registers has been improved and has been
moved to $(CPU)/thread.cpp. Threads can now be forked. A new CreateThread
function creates threads properly and portably.

Added a MicrosecondsSinceBoot() function.

Fixed a crucial bug in MemoryManagement::Fork().

Added an 'idle' user-space program that is a noop infinite loop, which is
used by the scheduler when there is nothing to do.

Rewrote the 'init' program such that it now forks off a shell, instead of
becoming the shell.

Added the $$ (current PID) and $PPID (parent PPID) variables to the shell.

66c058fba1 Refactored virtual memory management, making it less buggy. 
uintptr_t is now replaced with addr_t when referring to physical memory
addresses in Sortix. Many bugs in the previous memory management code have been
fixed. The new interface is less flexible - but should prove more solid as the
nasty internals have been hidden away. The current interface design should also
make the code more 64-bit ready/friendly. And so on.
