6367a2352e Added sforkr(2) that controls the child registers as well. 
sfork(2) now calls sforkr(2) with the current registers.

This will prove useful in creating threads, where user-space now can fully
control what state the child will start in. This is unlike the Linux clone
system call that accepts a pointer to the child stack; this is more powerful
and somehow simpler. Note that this will create a rather raw thread; no
thread initization has been done by the standard thread API (when it is
implemented), so this feature shouldn't be used by programmers unless they
know what they are doing.

fork(2) now calls sfork(2) directly. Also removed fork(2) and sfork(2) from
the kernel as they are done using sforkr(2) now. So technically they aren't
system calls right now, but that could always change.

6f36ecf0b3 execve(2) now pushes envp to the new stack and sets up registers. 
This fully implements environmental variables over exec.

60b9a84a51 execv(3) now passes environ(7) to execve(2). 2012-04-04 01:38:45 +02:00
Jonas 'Sortie' Termansen
33645eb347 <unistd.h> now declares environ(7) if _WANT_ENVIRON. 
Note that it is very bad style of programs to access it directly.

05b29ce25a Renamed rfork(2) to sfork(2) to avoid compatibility issues. 
sfork is much like rfork except sharing is default for everything.

Eventually, I'll make a rfork(3) wrapper function around sfork(2) to
provide compatibility to BSD programs.

I don't like Linux clone(2): that's some messy function.

2331a1a234 Added hacky support for environmental variables to the shell. 2012-04-03 22:03:58 +02:00
Jonas 'Sortie' Termansen
dd5157da6a Implemented setenv(3), putenv(3), getenv(3), clearenv(3), sortix_getenv(3), 
unsetenv(3), envlength(3), getenvindexed(3), and environ(7).

This provides the user-space foundation for environmental variables.

Note that this works over fork(2), but not execve(2) yet.

5d59f0ed03 Added EBOUND. 2012-04-02 20:24:56 +02:00
Jonas 'Sortie' Termansen
95a088fec5 Added a dummy implementation rfork(2) equal to fork(2). 
Note that in my implementation, you share per default, unless you ask.

Jonas 'Sortie' Termansen
c62eb09cdc Added stubs for pread(2) and pwrite(2). 
These are not implemented yet because the current kernel design is bad.

However, I need the stubs for other code.

db79994e64 Refactored all the sortix headers into a include directory. 
Also got rid of trailing white space. That corrupted .git/.

Big ass-commit because of recovered .git directory.

0f099c65ca The virtual memory fork code can now handle ENOMEM conditions. 
(forkbombs now don't panic the system!)

c9ab4fa6b4 The sortix vga terminal now can delete tabs and newlines properly. 
A nice little vga attribute array takes care of remembering what indexes
actually contains a character.

14a9149f17 Added detection for an obscure bug to let users know I know about it. 2012-03-18 17:36:31 +01:00

d564603460 Fixed kernel stack overflow and premature EOF in the unix pipe code. 
This usually caused the system to lock up when much data was transferred
over pipes, for instance: $ cd /bin ; cat cat | cat

c7c0fc603a Fixed initial kernel stack being wrong size. 2012-03-17 20:17:12 +01:00

969c0e8048 Cleaned up sortix/kernel.cpp and it now uses the new coding style. 
All kernel.cpp code related to jssortix was removed as it is not supported
any longer.

4f3e22140c Fixed x64 memory leaks upon process termination. 2012-03-17 18:14:57 +01:00

0364ce6f55 Added a new COM Port driver. 
Any detected COM ports available as /dev/comN.

It currently utilizes AGAIN to do polling in user-space. This prevents it
from locking up the whole system and makes it respond to the SIGINT hack.

There is also a more reliable and faster polling-blocking mode, but it locks
up the entire system.

The main interrupt mode is broken, perhaps by a bug in VirtualBox.

Jonas 'Sortie' Termansen
1ff0321400 Added a stub for Syscall::Yield() which is used by broken code. 
The whole system call interface is currently stupid.

fa6d445b0d Added type(1), a replacement for the "traditional" Sortix cat(1). 
cat(1) now work as you would expect.
