| 2018-10-31 | Fix wrong allocation size used in opendir(). | Andreas Kling | |
| 2018-10-31 | Use ALWAYS_INLINE for ctype inlines. | Andreas Kling | |
| 2018-10-31 | Fix ls build. | Andreas Kling | |
| 2018-10-31 | More LibC portability work while trying to get figlet building. | Andreas Kling | |
| 2018-10-31 | A bunch of LibC boilerplate stuff added while trying to get figlet to build. | Andreas Kling | |
| 2018-10-31 | Snazz up the sh prompt a bit. Add the current tty to it. | Andreas Kling | |
| 2018-10-31 | Implement basic sys$kill() and add a /bin/kill | Andreas Kling | |
| All it can do right now is send SIGKILL which just murders the target task. | |||
| 2018-10-31 | Fuck it, add a 4th virtual console. :^) | Andreas Kling | |
| 2018-10-31 | Add assertion that RTC year is >= 2018. | Andreas Kling | |
| 2018-10-31 | Minor cleanup. | Andreas Kling | |
| 2018-10-31 | Pass the register dump to syscall_entry() via an argument. | Andreas Kling | |
| I'm not sure why this was using a global, but it was very racy and made processes walk over each other when multiple processes were doing syscalls simultaneously. | |||
| 2018-10-30 | Minor VGA cleanup. | Andreas Kling | |
| 2018-10-30 | Fix bug where Console::the() was initialized too late. | Andreas Kling | |
| Yet another problem due to lack of BSS zeroing in the kernel loader... | |||
| 2018-10-30 | Add sys$ttyname_r and ttyname_r() + ttyname(). | Andreas Kling | |
| And print a greeting when sh starts up so we know which TTY we're on. | |||
| 2018-10-30 | sh should read from fd 0 (stdin) instead of /dev/keyboard. | Andreas Kling | |
| 2018-10-30 | Fix crashy bug where we'd try to deactivate VC -1 on boot. | Andreas Kling | |
| 2018-10-30 | Virtual consoles kinda work! | Andreas Kling | |
| We now make three VirtualConsoles at boot: tty0, tty1, and tty2. We launch an instance of /bin/sh in each one. You switch between them with Alt+1/2/3 How very very cool :^) | |||
| 2018-10-30 | Start working on virtual consoles/TTYs. | Andreas Kling | |
| This is a mess right now, but I'd rather commit as I go. | |||
| 2018-10-30 | Basic support the backspace key. | Andreas Kling | |
| This doesn't mean we get any line editing just yet. But the keyboard device now recognizes the backspace key, and the console device knows what to do with the backspace characters. | |||
| 2018-10-30 | Hang if a task crashes while it's already crashing.. | Andreas Kling | |
| 2018-10-30 | Implement sys$getcwd properly. | Andreas Kling | |
| Also fixed broken strcpy that didn't copy the null terminator. | |||
| 2018-10-29 | Add an inode metadata cache to the ext2fs implementation. | Andreas Kling | |
| 2018-10-29 | Improve ps output. | Andreas Kling | |
| 2018-10-29 | Okay let's just not have this broken locking at all right now. | Andreas Kling | |
| I think I should just protect access to shared data structures and eventually do read/write atomicity locks at the inode level. | |||
| 2018-10-29 | Fix broken SpinLock. | Andreas Kling | |
| The SpinLock was all backwards and didn't actually work. Fixing it exposed how wrong most of the locking here is. I need to come up with a better granularity here. | |||
| 2018-10-28 | Fix up VFS::resolveSymbolicLink() to use a base inode instead of a base path. | Andreas Kling | |
| Also more VFS error plumbing. | |||
| 2018-10-28 | Add basic symlink support. | Andreas Kling | |
| - sys$readlink + readlink() - Add a /proc/PID/exe symlink to the process's executable. - Print symlink contents in ls output. - Some work on plumbing options into VFS::open(). | |||
| 2018-10-28 | Add a VFS::absolutePath(InodeIdentifier). | Andreas Kling | |
| This is pretty inefficient for ext2fs. We walk the entire block group containing the inode, searching through every directory for an entry referencing this inode. It might be a good idea to cache this information somehow. I'm not sure how often we'll be searching for it. Obviously there are multiple caching layers missing in the file system. | |||
| 2018-10-28 | Add zone dump to /proc/mm. | Andreas Kling | |
| Sweet, now we can look at all the zones (physical memory) currently in play. Building the procfs files with ksprintf and rickety buffer presizing feels pretty shoddy but I'll fix it up eventually. | |||
| 2018-10-28 | Add /proc/mm and a /bin/mm utility that just dumps it. | Andreas Kling | |
| This shows some info about the MM. Right now it's just the zone count and the number of free physical pages. Lots more can be added. Also added "exit" to sh so we can nest shells and exit from them. I also noticed that we were leaking all the physical pages, so fixed that. | |||
| 2018-10-28 | Add subregions to /proc/PID/vm | Andreas Kling | |
| 2018-10-28 | Add sys$set_mmap_name and use it from LibC's malloc. | Andreas Kling | |
| It's nice to be able to identify mmap's in /proc/PID/vm. | |||
| 2018-10-28 | Canonicalize the path used by sh. | Andreas Kling | |
| With a bunch of LibC work to support the feature. LibC now initializes AK::StringImpl by default. It's now fine to use AK in LibC/Userland! :^) | |||
| 2018-10-28 | Add a simple FileSystemPath class that can canonicalize paths. | Andreas Kling | |
| Also a simple StringBuilder to help him out. | |||
| 2018-10-28 | Add save/unsave cursor escape sequences. | Andreas Kling | |
| Also added a little terminal test program called /bin/tst. | |||
| 2018-10-28 | Stop committing changes to _fs_contents and generate it in the sync script. | Andreas Kling | |
| 2018-10-28 | Colorize ls output. | Andreas Kling | |
| 2018-10-28 | Give the shell a nice, colorful prompt. | Andreas Kling | |
| The cwd looks like crap, I need to write some code to strip out ".." and extra slashes from the path string. | |||
| 2018-10-28 | Add basic support for ANSI color escape sequences. | Andreas Kling | |
| 2018-10-27 | Implement 'H' and 'J' escape sequences. | Andreas Kling | |
| 2018-10-27 | Add a /bin/clear that prints the clear terminal escape sequence. | Andreas Kling | |
| It doesn't work yet, but it will! | |||
| 2018-10-27 | Add some basic field width support to printf(). | Andreas Kling | |
| Use it to make "ls" output a bit better. Also sys$spawn now fails with EACCES if the path is not a file that's executable by the current uid/gid. | |||
| 2018-10-27 | Rename "kernel map" concept to just "ksyms" | Andreas Kling | |
| 2018-10-27 | Implement loading of linked ELF executables. | Andreas Kling | |
| This took me a couple hours. :^) The ELF loading code now allocates a single region for the entire file and creates virtual memory mappings for the sections as needed. Very nice! | |||
| 2018-10-27 | Enable A20 line at boot. | Andreas Kling | |
| 2018-10-27 | Better int hashing. This was going to bite me sooner or later. | Andreas Kling | |
| 2018-10-27 | Implement waitpid() support for getting the waitee's exit code. | Andreas Kling | |
| 2018-10-27 | Remove the obsolete "Userspace" stuff. | Andreas Kling | |
| 2018-10-27 | Turn off the floppy drive after the boot loader is finished. | Andreas Kling | |
| 2018-10-27 | Use Unix::stat for sys$lstat(). | Andreas Kling | |
